Strategies and Protocols for Optimized Genome Editing in Potato.

The potato family includes a highly diverse cultivar repertoire and has a high potential for nutritional yield improvement and refinement but must in line with other crops be adapted to biotic and abiotic stresses, for example, accelerated by climate change and environmental demands. The combination of pluripotency, high ploidy, and relative ease of protoplast isolation, transformation, and regeneration together with clonal propagation through tubers makes potato highly suitable for precise genetic engineering. Most potato varieties are tetraploid having a very high prevalence of length polymorphisms and small nucleotide polymorphisms between alleles, often complicating CRISPR-Cas editing designs and strategies.

Use of non-barrier contraceptives among women with human immunodeficiency virus; a nationwide, matched cohort study.

Design: Nationwide population-based matched cohort study.

Methods: We included WWH aged 16-50, treated at an HIV specialized clinic, and included in The Danish HIV Cohort Study between 1995-2021 and an age-matched comparison cohort of WGP.

Importance of environmental signals for cardiac morphological development in Atlantic salmon.

The hearts of salmonids display remarkable plasticity, adapting to various environmental factors that influence cardiac function and demand. For instance, in response to cold temperature, the salmonid heart undergoes growth and remodeling to counterbalance the reduced contractile function associated with dropping temperatures. Alongside heart size, the distinct pyramidal shape of the wild salmonid heart is essential for optimal cardiac performance, yet the environmental drivers behind this optimal cardiac morphology remain to be fully understood.

ACE2 and TMPRSS2 in human kidney tissue and urine extracellular vesicles with age, sex, and COVID-19.

SARS-CoV-2 virus infects cells by engaging with ACE2 requiring protease TMPRSS2. ACE2 is highly expressed in kidneys. Predictors for severe disease are high age and male sex.

Antibody response to SARS-CoV-2 mRNA vaccination in Danish adults exposed to perfluoroalkyl substances (PFASs): The ENFORCE study.

Introduction: Per- and polyfluoroalkyl substances (PFASs) have immunotoxic effects in children while studies in adults, including recent studies on the SARS-CoV-2 vaccine response have been less consistent. In a cohort of 50-69-year-olds repeatedly vaccinated against COVID-19 in Denmark from early 2021, we aimed to assess the association between serum-PFAS concentrations and SARS-CoV-2 antibody responses.

Methods: We assessed serum-PFAS concentrations among 371 middle-aged adults from the National Cohort Study of Effectiveness and Safety of SARS-CoV-2 vaccines (ENFORCE) who had received their first vaccination against COVID-19.

Importance of immunosuppression in haemophagocytic lymphohistiocytosis caused by miliary tuberculosis.

Haemophagocytic lymphohistiocytosis (HLH) is a syndrome with an abnormal activation of the immune system and is associated with a high mortality even with treatment. We present a case of a woman in her mid-50s who developed HLH triggered by miliary tuberculosis (TB) while receiving a tumour necrosis factor alpha inhibitor.The patient was admitted with a high fever and respiratory pain.

Self-injurious thoughts and behaviours as the reason for contact to Norwegian emergency primary care centres: an observational study.

Objective: To describe and compare contacts regarding self-injurious thoughts and behaviours to other contacts to emergency primary care.

Design: Observational study.

Setting: A sentinel network of seven emergency primary care centres throughout Norway.

Influence of temperature and precipitation on dengue incidence in Campinas, São Paulo State, Brazil (2013-2022).

Background: Global dengue cases are rising, notably in Brazil.

Methods: By using monthly data, we estimated linear regressions with ARIMA errors to measure the influence of temperature and precipitation on dengue incidence in the city of Campinas, São Paulo State, Brazil.

Results: Findings suggest that a 1°C increase in mean temperature can lead to a cumulative increase of up to 40% in dengue incidence within 2 months.

Lower Microscopy Sensitivity with Decreasing Malaria Prevalence in the Urban Amazon Region, Brazil, 2018-2021.

Malaria is increasingly diagnosed in urban centers across the Amazon Basin. In this study, we combined repeated prevalence surveys over a 4-year period of a household-based random sample of 2,774 persons with parasite genotyping to investigate the epidemiology of malaria in Mâncio Lima, the main urban transmission hotspot in Amazonian Brazil. We found that most malarial infections were asymptomatic and undetected by point-of-care microscopy.

Mortality Rate and Cause of Death in Adults with Extrapulmonary Nontuberculous Mycobacteria Infection, Denmark.

Evidence on mortality rates and causes of death associated with extrapulmonary nontuberculous mycobacteria (NTM) infection is limited. This nationwide register-based study in Denmark used diagnostic codes to match adult patients with extrapulmonary NTM infection 1:4 to controls. During 2000–2017, we identified 485 patients, who had significantly more comorbidities than controls.

Risk of tuberculosis after initiation of antiretroviral therapy among persons with HIV in Europe.

Objectives: Tuberculosis (TB) risk after initiation of antiretroviral treatment (ART) is not well described in a European setting, with an average TB incidence of 25/10 in the background population.

Methods: We included all adult persons with HIV starting ART in the RESPOND cohort between 2012 and 2020. TB incidence rates (IR) were assessed for consecutive time intervals post-ART initiation.

Infections in pregnancy are common, and although often not harmful to the woman or her unborn child, some infections may be associated with severe adverse outcomes. Pregnancy causes physiological and immunological adaptations which may make pregnant women more susceptible to infections and at increased risk of more severe illness. Infections in pregnancy represent a challenging area of concern for many specialists and general practitioners.

Pivoting From Influenza to COVID-19 Vaccinations: How a Minnesota Vaccination Program Reduced Barriers for Refugee, Immigrant, and Migrant Communities Accessing Vaccines During the COVID-19 Pandemic.

The Minnesota Immunization Networking Initiative (MINI) led by Fairview Health Services has addressed barriers to accessing immunizations through partnerships with community organizations to provide free influenza vaccinations to historically underserved communities, especially refugee, immigrant, and migrant communities. Once the COVID-19 vaccine was available, MINI quickly pivoted operations to distribute the vaccine and provide technical assistance to community partners amidst rapidly evolving guidance. With infrastructure and a vaccination team in place, MINI responded to new and emerging needs, eg, implementing a more accessible and low-tech scheduling system, increasing staffing to meet growing needs, and expanding partnerships with community organizations and leaders.
