Human resource challenges in health systems : evidence from 10 African countries

Sub-Saharan Africa has fewer medical workers per capita than any region of the world, and that shortage has been highlighted consistently as a critical constraint to improving health outcomes in the region. This paper draws on newly available, systematic, comparable data from 10 countries in the region to explore the dimensions of this shortage. We find wide variation in human resources performanc

Different or the same? exploring the physicochemical properties and molecular mobility of celecoxib amorphous forms

The influence of different preparation methods on the physicochemical properties of amorphous solid forms have gained considerable attention, especially with recent publications on pharmaceutical polyamorphism. In the present study, we have investigated the possible occurrence of polyamorphism in the drug celecoxib (CEL) by investigating the thermal behavior, morphology, structure, molecular mobil

Diagnostic reliability of monitoring for premature atrial and ventricular complexes

Aims Short-term ambulatory electrocardiogram (ECG) monitoring is often used to assess premature atrial complex (PAC) and premature ventricular complex (PVC) frequency, but the diagnostic reliability is unknown. The objective of this study was to study the day-to-day variability of PAC and PVC frequency. Methods We used 14-day full-disclosure mobile cardiac telemetry recordings without atrial fibri

Plasticity for the win : Flexible transcriptional response to host plant switches in the comma butterfly (Polygonia c-album)

Generalist plant-feeding insects are characterised by a broad host repertoire that can comprise several families or even different orders of plants. The genetic and physiological mechanisms underlying the use of such a wide host range are still not fully understood. Earlier studies indicate that the consumption of different host plants is associated with host-specific gene expression profiles. It

Differential phase-amplitude coupling in nucleus accumbens and orbitofrontal cortex reflects decision-making during a delay discounting task

Background: The impulsive choice is characterized by the preference for a small immediate reward over a bigger delayed one. The mechanisms underlying impulsive choices are linked to the activity in the Nucleus Accumbens (NAc), the orbitofrontal cortex (OFC), and the dorsolateral striatum (DLS). While the study of functional connectivity between brain areas has been key to understanding a variety o

A comprehensive map of proteoglycan expression and deposition in the pulmonary arterial wall in health and pulmonary hypertension

Changes in the extracellular matrix of pulmonary arteries (PAs) are a key aspect of vascular remodeling in pulmonary hypertension (PH). Yet, our understanding of the alterations affecting the proteoglycan (PG) family remains limited. We sought to investigate the expression and spatial distribution of major vascular PGs in PAs from healthy individuals and various PH groups (chronic obstructive pulm

Carbon and Greenhouse Gas Budgets of Europe : Trends, Interannual and Spatial Variability, and Their Drivers

In the framework of the RECCAP2 initiative, we present the greenhouse gas (GHG) and carbon (C) budget of Europe. For the decade of the 2010s, we present a bottom-up (BU) estimate of GHG net-emissions of 3.9 Pg CO2-eq. yr−1 (using a global warming potential on a 100 years horizon), which are largely dominated by fossil fuel emissions. In this decade, terrestrial ecosystems acted as a net GHG sink o

Views on Nurses' Understanding of a Holistic Approach to Nursing : A Qualitative Review and Thematic Analysis

It is assumed that nursing is performed on a scientific knowledge-based approach toward patients that considers the wellbeing of the whole person. The meaning and understanding are essentialwhen conceptualizing the idea of caring for the whole person and how this is applied by nurses inhealthcare. However, the meaning and understanding of holism varies widely according to research. The aim of this

Random Normal Matrices : Eigenvalue Correlations Near a Hard Wall

We study pair correlation functions for planar Coulomb systems in the pushed phase, near a ring-shaped impenetrable wall. We assume coupling constant Γ=2 and that the number n of particles is large. We find that the correlation functions decay slowly along the edges of the wall, in a narrow interface stretching a distance of order 1/n from the hard edge. At distances much larger than 1/n, the effe

Political economy versus political Economy: bringing back classical political economy into geographic research

Since the launch of radical geography, the questions of capital’s spatial dynamics and the consequent socio-spatial relations, such as the evolving ‘North-South’ relation touched on in the conference call, have been central to the field. However, according to Kevin Cox (2013), already from the 1980s with the rise of critical realism as the dominant theory of science, classical (Marxist) political

Factors associated with COVID-19 vaccine uptake among south African health care workers

Background: Identifying factors associated with vaccine uptake among health care workers (HCWs) remains crucial to generating evidence aimed at guiding national COVID-19 vaccination and future infectious disease outbreak strategies. This study aimed to elucidate these factors, focusing on the interplay between socio-demographic, health, knowledge, beliefs and attitudinal indicators. Methods: This

Endophthalmitis after cataract surgery and effect of different intracameral antibiotic regimes in Sweden 2011-2017 : National registry study

Purpose:To study the incidence, predictive factors, etiology, and visual consequences of postoperative endophthalmitis (PE) in relation to 3 intracameral (IC) antibiotic regimes.Setting:Swedish National Cataract Register entries from 2011 through 2017.Design:Observational retrospective study.Methods:PE incidence, influencing factors, bacteriology, and visual outcome were analyzed regarding the 3 m

Proton Transfer Kinetics in Histidine Side Chains Determined by pH-Dependent Multi-Nuclear NMR Relaxation

Histidine is a key amino-acid residue in proteins with unique properties engendered by its imidazole side chain that can exist in three different states: two different neutral tautomeric forms and a protonated, positively charged one with a pKa value close to physiological pH. Commonly, two or all three states coexist and interchange rapidly, enabling histidine to act as both donor and acceptor of

Deeper Insight of the Conformational Ensemble of Intrinsically Disordered Proteins

It is generally known that, unlike structured proteins, intrinsically disordered proteins, IDPs, exhibit various structures and conformers, the so-called conformational ensemble, CoE. This study aims to better understand the conformers that make up the IDP ensemble by decomposing the CoE into groups separated by their radius of gyration, Rg. A common approach to studying CoE for IDPs is to use low

Unravelling primary δ[18]O signatures of the 1730-36 Timanfaya parental magmas on Lanzarote

Lanzarote is an island that is part of the intraplate ocean island volcanism that makes up the Canary archipelago. The Timanfaya eruption (1730-36) was a crucial event in the geological history of Lanzarote. It is considered an anomaly in the volcanic record of the archipelago due to its long eruptive activity, large volume of lava and composition (alkali basalts evolving into tholeiites). The ori

Systemic Risk and Default Contagion in Financial Networks: Identifying Systemically Important Banks

This thesis uses real data from the Bank of International Settlements to create financial networks for the interbank market using five different methods for network reconstruction. The goal is to analyze how defaults propagate to assess the importance of banks and to examine how the network’s structure affects the system’s vulnerability. By applying network theory, communicability theory, and the

KRATOS : A large suite of N -body simulations to interpret the stellar kinematics of LMC-like discs

Context. The Large and Small Magellanic Clouds (LMC and SMC, respectively) are the brightest satellites of the Milky Way (MW), and for the last thousand million years they have been interacting with one another. As observations only provide a static picture of the entire process, numerical simulations are used to interpret the present-day observational properties of these kinds of systems, and mos

Advanced Chemometric analysis of photoemission Electron microscopy imaging for detecting non-metallic inclusions in steel materials

The accurate identification of non-metallic inclusions (NMIs) within steel matrices is critical for high-quality steel production. This study employs synchrotron radiation-based X-ray absorption photoemission electron microscopy (X-PEEM) to investigate NMIs in ultra-high-strength steels. Ca-L2,3-edge X-ray absorption spectra were acquired for six NMIs at both room temperature and 400 °C, allowing
