Drawing on qualitative data from the project 'COVID-19 Impact Tracing in Ethiopia Social, Economic, Political, and Security Ramifications', carried out in the Tigray, Amhara and Oromia Regional States (RS) from June to September 2020, we offer new empirical and theoretical perspectives that shed light on the political status of health and health policies in Ethiopia and beyond. In all the three regions, COVID-19 and the government's pandemic response was subject to politicization and securitization. The degree of securitization and politicization differed between the regions and fluctuated over time; in areas with strong opposition to political authorities, the COVID-19 mitigating efforts were-during the first phase of the pandemic-more politicized and securitized than in areas with less opposition. Yet, as the political opposition and instability increased, threatening national security and Prime Minister Abiy Ahmed's political project, the authorities and the public paid increasingly less attention to the pandemic and the mitigating policies. In our analysis of these dynamics, we draw on a classic distinction that scholars of global public health have borrowed from political science that of 'low' and 'high' politics. We argue that a contextually situated use of the high/low distinction allows us to recognize the fleeting and context-dependent nature of health's political status, providing valuable insights that help us understand the ways that health emerges and disappears as high politics. The temporal and inter-regional shifts that appeared in, and as a response to, Ethiopia's pandemic policies illustrate the importance of a continuous analysis of the relationships between health and politics at national as well as at sub-national levels.
Anaemia is common in patients with acute myocardial infarction (MI). We investigated the association of high-sensitivity cardiac troponin (hs-cTn) and haemoglobin (Hb) and the influence of anaemia on the performance of diagnostic protocols for suspected MI.

Patients with suspected MI were consecutively enrolled at a tertiary centre. Final diagnoses were independently adjudicated by two cardiologists. Performance measures of hs-cTn-based algorithms were compared for anaemic and non-anaemic patients (Hb <12 g/dL in women and <13 g/dL in men). The influence of anaemia on survival (median follow-up 1.7 years) was investigated using multivariable cox-regression analysis and the association of Hb and hs-cTn by multivariable linear regression analysis. Overall, 2223 patients were included, of whom 415 (18.7%) had anaemia. In anaemic patients, the incidence of MI was similar; however, chronic myocardial injury was significantly more prevalent (20.1% vs. 48.2%). The negative predictive value to rule-out MI was similar for both algorithms and all assays in patients with anaemia, although the positive predictive value to rule-in MI was partly reduced for the 0/3-h algorithm. Fewer anaemic patients were triaged after 1 h. Anaemia was an independent predictor of death. Adjusted for patient characteristics, Hb was significantly associated with hs-cTn. GSK-3 signaling pathway By providing a point-based tool, the Hb-associated hs-cTn concentration and thus chronic myocardial injury may be predicted.

Anaemia partly affects the rule-in, but not the rule-out of MI in hs-cTn-based diagnostic protocols. Hs-cTn concentrations and thus chronic myocardial injury may be predicted by clinical variables and Hb.

We performed subgroup analyses of the AFTER I-O study to clarify the association of time-to-treatment failure (TTF) and discontinuation reason of prior immune-oncology (I-O) therapy, and molecular targeted therapy (TT) regimen with the outcomes of TT after I-O.

The data of Japanese metastatic renal cell carcinoma patients treated with TT after nivolumab (NIVO) (CheckMate 025) or NIVO + ipilimumab (IPI) (CheckMate 214) were retrospectively analyzed. The objective response rates (ORRs), progression-free survival (PFS) and overall survival (OS) of TT after I-O were analyzed by subgroups TTF (<6 or≥6months) and discontinuation reason of prior I-O (progression or adverse events), and TT regimen (sunitinib or axitinib). We also analyzed PFS2 of prior I-O and OS from first-line therapy.

The ORR and median PFS of TT after NIVO and NIVO+IPI among the subgroups was 17-36% and 20-44%, and 7.1-11.6months and 16.3-not reached (NR), respectively. The median OS of TT after NIVO was longer in patients with longer TTF of NIVO and treated with axitinib. Conversely, median OS of TT after NIVO+IPI was similar among subgroups. The median PFS2 of NIVO and NIVO+IPI was 36.7 and 32.0months, respectively. The median OS from first-line therapy was 70.5months for patients treated with NIVO and NR with NIVO+IPI. The safety profile of each TT after each I-O was similar to previous reports.

The efficacy of TT after NIVO or NIVO+IPI was favorable regardless of the TTF and discontinuation reason of prior I-O, and TT regimen.

Congenital heart disease (CHD) is an important cause of childhood morbidity. The birth prevalence and distribution of CHD among neonates in a tertiary hospital in Nigeria was determined.

This descriptive, cross-sectional study involved consecutive neonates in the neonatal and postnatal wards of the hospital. Bedside echocardiography was conducted on all neonates. Data entry and analysis was done with IBM-SPSS version 20.0.

A total of 2 849 neonates were recruited, consisting of 1 482 (52.0%) males. Forty-one neonates had CHD, giving a birth prevalence of 14.4/1 000 live births. Of the 41 with CHD, 21 (51.2%) were male. Thirty-six (87.8%) neonates had acyanotic CHD, of which the commonest was isolated ventricular septal defect [11 (26.8%)]. Transposition of the great arteries [3 (7.3%)] was the commonest cyanotic CHD.

The birth prevalence of 14.4/1 000 live births in this study is high and buttresses the need for strengthening existing cardiac services in Nigeria.

Its dynamic nature endows selenium-containing polymers with striking sensitivity towards some environmental alterations. In the past decade, several selenium-containing polymers were synthesized and used for the preparation of oxidation-, reduction-, and radiation-responsive nanocarriers. Recently, thioredoxin reductase, sonication, and osmotic pressure triggered the cleavage of Se-Se bonds and swelling or disassembly of nanostructures. Moreover, some selenium-containing nanocarriers form oxidation products such as seleninic acids and acrylates with inherent anticancer activities. Thus, selenium-containing polymers hold promise for the fabrication of ultrasensitive and multifunctional nanocarriers of radiotherapeutic, chemotherapeutic, and immunotherapeutic significance. Herein, we discuss the most recent developments in selenium-containing polymeric micelles in light of their architecture, multiple stimuli-responsive properties, emerging immunomodulatory activities, and future perspectives in the delivery and controlled release of anticancer agents.Nearly fifty years ago Lovinger and Gryte suggested that the directional crystallization of a polymer was analogous to the quiescent isothermal crystallization experiment but at a supercooling where the crystal growth velocity was equal to the velocity of the moving front. Our experiments showed that this equivalence holds in a detailed manner at low directional velocities. To understand the underlying physics of these situations, we modeled the motion of a crystallization front in a liquid where the left side boundary is suddenly lowered below the melting point (Stefan's problem) but with the modification that the crystallization kinetics follow a version of the Avrami model. Our numerical results surprisingly showed that the results of the polymer analog track with the Stefan results which were derived for a simple liquid that crystallizes completely at its melting point; in particular, the position of the crystal growth-front evolved with time exactly as in the Stefan problem. The numerical solution also showed that the temperature in the immediate vicinity of the growth-front decreased with increasing front velocity, which is in line with Lovinger and Gryte's ansatz. To provide a clear theoretical understanding of these numerical results we derive a boundary layer solution to the governing coupled differential equations of the polymer problem. The analytical results are in agreement with our observations from experiments and numerical computations but show that this equivalence between the small molecule and polymer analog only holds in the limit where the crystallization enthalpy is much larger than the rate at which heat is conducted away in the polymer. In particular, in the context of the temperature profile, the enthalpy generated by the crystallisation process which is spread out over a narrow spatial region can be approximated as a point source whose location and temperature correspond to the Lovinger-Gryte ansatz.At low temperature, spontaneous (zero-field-cooled, SEB) and traditional (field-cooled) exchange bias effects may be induced in a series of NiMn-based Heusler alloys, and the exchange bias is commonly sensitive to alloying elements and compositions, while the mechanisms especially for SEB are still elusive. Therefore, the SEB in Mn-rich Heusler alloys with coexistence of ferromagnetic and antiferromagnetic exchange interactions is numerically studied by performing a modified Monte Carlo simulation. The intrinsic magnetocrystalline anisotropies (KAF), exchange interactions (JFM-AF and JAF-AF), and occupation probabilities (xFM) are directly tuned to establish their dependencies of zero-field-cooled/field-cooled thermomagnetic curves and zero-field-cooled magnetization hysteresis loops. The results indicate that the freezing temperature is monotonically enhanced with increasing KAF and varies nonmonotonically with other parameters, and at 5 K, the irreversibility arising from antiferromagnetic components becomes high enough to trigger SEB even though no spin glass state exists. The SEB is nonmonotonic with KAF, JFM-AF, JAF-AF, and xFM, and its maximum value will be obtained at KAF = 4.5 × 106 J m-3, JFM-AF = 5 meV, JAF-AF = -5 meV, or xFM = 0.3. On the contrary, the coercivity is also nonmonotonic with KAF and JFM-AF while monotonic with JAF-AF and xFM. The values of the SEB field are nearly one order of magnitude smaller than those of coercivity, consistent with experimental data. The magnetic relaxation properties are calculated to propose two factors, i.e., ferromagnetic-like domain between ferromagnetic and antiferromagnetic components and decay rate, to determine the final SEB. This work demonstrates the mechanisms to optimize SEB in Mn-rich Heusler alloys, and physically the results obtained are also suitable for other material systems with spontaneous ferromagnet/antiferromagnet phase separations.
