Introduction Studies from the first pandemic wave found associations between COVID-19 hospital load and mortality. Here, we aimed to study if mortality of hospitalized COVID-19 patients was associated with the COVID-19 admission rate during a full year of the pandemic in Sweden. Method Observational review of all patients admitted to hospital with COVID-19 in Sweden between March 2020 and February 2021 (n = 42,017). Primary outcome was 60-day all-cause mortality related to number of COVID-19 hospital admissions per month/100,000 inhabitants. Poisson regression was used to estimate the relative risk for death by month of admission, adjusting for pre-existing factors. Results The overall mortality was 17.4%. Excluding March 2020, mortality was clearly correlated to the number of COVID-19 admissions per month (coefficient of correlation rho=.96; p<.0001). After adjustment for pre-existing factors, the correlation remained significant (rho=.75, p=.02). Patients admitted in December (high admission rate and high mortality) had more comorbidities and longer hospital stays, and patients treated in intensive care units (ICU) had longer pre-ICU hospital stays and worse respiratory status on ICU admission than those admitted in July to September (low admission rate and low mortality). Conclusion Mortality in hospitalized COVID-19 patients was clearly associated with the COVID-19 admission rate. Admission of healthier patients between pandemic waves and delayed ICU care during wave peaks could contribute to this pattern. The study supports measures to flatten-the-curve to reduce the number of COVID-19 patients admitted to hospital., Funding Agencies|Swedens National Board of Health and Welfare

Background: It is important to know if mortality among hospitalised COVID-19 patients has changed as the pandemic has progressed. The aim of this study was to describe the dynamics over time of mortality among patients hospitalised for COVID-19 in Sweden, using nationwide data compiled by the Swedish National Board of Health and Welfare. Methods: Observational cohort study where all patients hospitalised in Sweden between March 1 and September 30, 2020, with SARS-CoV-2 RNA positivity 14 days before to 5 days after admission and a discharge code for COVID-19 were included. Outcome was 60-day all-cause mortality. Patients were categorised according to month of hospital admission. Poisson regression was used to estimate the relative risk of death by month of admission, adjusting for, age, sex, comorbidities, care dependency, country of birth, healthcare region, and Simplified Acute Physiology, version 3 (patients in intensive care units; ICU). Findings: A total of 17,140 patients were included, of which 2943 died within 60 days of admission. The overall 60-day mortality was thus 17.2% (95% CI, 16.6%-17.7%), and it decreased from 24.7% (95% CI, 23.0%-26.5%) in March to 10.4% (95% CI, 8.9%-12.1%) post-wave (July-September). Adjusted relative risk (RR) of death was 0.46 (95% CI, 0.39-0.54) post-wave, using March as reference. Corresponding RR for patients not admitted to ICU and those admitted to ICU were 0.49 (95% CI, 0.42-0.59) and 0.49 (95% CI, 0.33-0.72), respectively. The proportion of patients admitted to ICU decreased from 19.4% (95% CI, 17.9%-21.1%) in the March cohort to 8.9% (95% CI, 7.5%-10.6%) post-wave. Interpretation: There was a gradual decline in mortality during the spring of 2020 in Swedish hospitalised COVID-19 patients, independent of baseline patient characteristics. Future research is needed to explain the reasons for this decline. The changing COVID-19 mortality should be taken into account when management and results of studies from the first pande, Funding Agencies|Swedens National Board of Health and Welfare

Magnonic crystals are magnetic metamaterials, that provide a promising way to manipulate magnetodynamic properties by controlling the geometry of the patterned structures. Here, we study the magnetodynamic properties of 1D magnonic crystals consisting of parallel NiFe strips with different strip widths and separations. The strips couple via dipole-dipole interactions. As an alternative to experiments and/or micromagnetic simulations, we investigate the accuracy of a simple macrospin model. For the case of simple strips, a model with a single free parameter to account for an overestimation of the out of plane demagnetization of the magnonic lattice is described. By adjusting this parameter, a good fit with experimental as well as micromagnetic results is obtained. Moreover, the Gilbert damping is found independent of lattice constant however the inhomogeneous linewidth broadening found to increase with decreasing stripe separation.

Bakgrund: Prostatacancer är Sveriges vanligaste cancerform där de drabbade är äldre män. Ungefär en av 20 dör i sjukdomen, men trots detta är det många patienter som ser det som en dödsdom. Män med prostatacancer blir påverkade av sin sjukdom i deras vardag, deras fysiska och emotionella hälsa samt i deras sociala liv. Syfte: Syftet med studien var att beskriva mäns upplevelser av att drabbas av prostatacancer. Metod: Fem narrativa berättelser i form av självbiografier har analyserats genom kvalitativ innehållsanalys med induktiv ansats. Resultat: Resultatet belyser mäns upplevelser av att drabbas av prostatacancer. Männen upplevde känslor av rädsla, oro och hopp samtidigt som de upplevde en förändrad livssituation och social tillvaro. De bearbetade det på olika sätt. Diskussion: Männen upplevde sin livskvalitet försämrad som konsekvens av ovisshet och begränsningar samtidigt som den främjades genom information, stöd och acceptans. De upplevde det svårt att välja behandling och behövde därför sjuksköterskans stöd. Konklusion: Stöd från sjuksköterskor och läkare anses vara betydelsefullt för att främja en god hälsa. Att förstå hur män med prostatacancer upplever sin förändrade livssituation kan hjälpa sjuksköterskor att bemöta dem på bästa sätt., Background: Prostate cancer is Sweden´s most common form of cancer where the victims are mostly older men. About one in 20 dies from the disease, but despite this, many patients see it as a death sentence. Men with prostate cancer are getting affected every day in their social life, their physical and emotional health. Purpose: The purpose of the study was to describe men´s experiences of suffering from prostate cancer. Method: Five narrative stories in the form of autobiographies have been analyzed through qualitative content analysis with an inductive approach. Results: The result illustrates men´s experiences of suffering from prostate cancer. Men experience feelings of fear, anxiety and hope at the same time as they experience an alteration in their life situation and social existence. They process it in different ways. Discussion: Men experience a deterioration in their quality of life as a consequence of uncertainty and limitations while being promoted through information, support and acceptance. They find it difficult to choose treatment and therefore need the nurse´s support. Conclusion: Support from nurses and doctors is considered important for promoting good health. A better understanding for men whom experience their changed life situation, can help nurses respond and help them in the best way.

Aim: To describe the Swedish Neonatal Quality Register (SNQ) and to determine its completeness and agreement with other registers. Methods: SNQ collects data for infants admitted to neonatal units during the first four postnatal weeks. Completeness and registers' agreement were determined cross-linking SNQ data with Swedish population registers (the Inpatient, Medical Birth and Cause of Death Registers) for a study period of five years. Results: In total, 84 712 infants were hospitalised. A total of 52 806 infants occurred in both SNQ and the population registers; 28 692 were only found in the population registers, and 3214 infants were only found in SNQ. Between gestational weeks 24-34, completeness of SNQ was 98-99%. Below and above these gestational ages, completeness was lower. Infants missing in SNQ were term or near-term in 99% of the cases, and their diagnoses indicated conditions managed in maternity units, or re-admissions for acute infections, managed in paediatric units. For most diagnoses, the agreement between SNQ and population registers was high, but some (bronchopulmonary dysplasia and grade of hypoxic-ischaemic encephalopathy) were often missing in the population registers. Conclusion: SNQ completeness and agreement against other registers, especially for preterm infants, is excellent. SNQ is a valid tool for benchmarking, quality improvement and research.

The use of periodic magnetic structures to control the magneto-dynamic properties of materials-magnonics-is a rapidly developing field. In the last decade, a number of studies have. shown that metallic films can be patterned or combined in patterns that give rise to well-defined magnetization modes,. which. are formed due to band folding or band gap effects. To explore and utilize these effects in a wide frequency range, it is necessary to pattern samples at the sub-micrometer scale. However, it is still a major challenge to produce low-loss magnonic structures with periodicities at such length scales. Here, we show that for a prototypical perovskite, La-0.7 Sr0.3MnO3, the twinned structural order can be used to induce a magnetic modulation with a period smaller than 100 nm, demonstrating a bottomup approach for magnonic crystal growth.

The collective dynamics in populations of magnetic spin torque oscillators (STO) is an intensely studied topic in modern magnetism. Here, we show that arrays of STO coupled via dipolar fields can be modeled using a variant of the Kuramoto model, a well-known mathematical model in non-linear dynamics. By investigating the collective dynamics in arrays of STO we find that the synchronization in such systems is a finite size effect and show that the critical coupling—for a complete synchronized state—scales with the number of oscillators. Using realistic values of the dipolar coupling strength between STO we show that this imposes an upper limit for the maximum number of oscillators that can be synchronized. Further, we show that the lack of long range order is associated with the formation of topological defects in the phase field similar to the two-dimensional XY model of ferromagnetism. Our results shed new light on the synchronization of STO, where controlling the mutual synchronization of several oscillators is considered crucial for applications.
