Continuous measurement in neurocritical care of cerebral blood flow (CBF) calculated from ICP and central venous pressure.

The cerebral blood flow, CBF, is an important clinical parameter in neuro-intensive care. The possibility to continuously monitor CBF, computed from referential ICP, rICP (calculated from measured intracranial pressure, ICP, and central venous pressure, CVP) and venous outflow resistance, Rv, could importantly improve patient care. For the CBF(1) method the pulsative part of CBF (with rICP increase due to vascular volume increase) gives the venous outflow resistance, Rv.

Fast-track recovery after surgery for perforated peptic ulcer safely shortens hospital stay: A systematic review and meta-analysis of six randomized controlled trials and 356 patients.

Background: Postoperative management after surgery for perforated peptic ulcer is still burdened by old traditions. All available data for fast-track recovery in this setting are either very unspecific or underpowered. The aim of this study was to evaluate fast-track recovery in this diagnosis-specific context in a larger sample.

Organisation of paediatric echocardiography laboratories and governance of echocardiography services and training in Europe: current status, disparities, and potential solutions. A survey from the Association for European Paediatric and Congenital Cardiology (AEPC) imaging working group.

Background: There is limited data on the organisation of paediatric echocardiography laboratories in Europe.

Methods: A structured and approved questionnaire was circulated across all 95 Association for European Paediatric and Congenital Cardiology affiliated centres. The aims were to evaluate: (1) facilities in paediatric echocardiography laboratories across Europe, (2) accredited laboratories, (3) medical/paramedical staff employed, (4) time for echocardiographic studies and reporting, and (5) training, teaching, quality improvement, and research programs.

ECP versus ruxolitinib in steroid-refractory chronic GVHD - a retrospective study by the EBMT transplant complications working party.

Ruxolitinib has become the new standard of care for steroid-refractory and steroid-dependent chronic GVHD (SR-cGVHD). Our aim was to collect comparative data between ruxolitinib and extracorporeal photophoresis (ECP). We asked EBMT centers if they were willing to provide detailed information on GVHD grading, -therapy, -dosing, -response and complications for each included patient.

The genome of the pygmy right whale illuminates the evolution of rorquals.

Background: Baleen whales are a clade of gigantic and highly specialized marine mammals. Their genomes have been used to investigate their complex evolutionary history and to decipher the molecular mechanisms that allowed them to reach these dimensions. However, many unanswered questions remain, especially about the early radiation of rorquals and how cancer resistance interplays with their huge number of cells.

Acute burn care and outcomes at the Hospital Nacional Guido Valadares (HNGV), Timor-Leste: A 7-year retrospective study.

The purpose of this study was to describe the epidemiology of patients presenting with acute burns and undergoing admission at Hospital Nacional Guido Valadares (HNGV) in Dili, Timor-Leste in the period 2013 to 2019. HNGV is the only tertiary referral hospital in Timor-Leste. This was a retrospective study involving all acute burn patients admitted to the surgical wards of HNGV from 2013 to 2019.

The effect of a randomised controlled lifestyle intervention on weight loss and plasma proneurotensin.

Aims: Proneurotensin (Pro-NT) is a strong predictor of cardiometabolic disease including type 2 diabetes and obesity, however, the effect of lifestyle change on Pro-NT has not been investigated in this context. Middle Eastern (ME) immigrants represent the largest and fastest growing minority population in Europe and are a high-risk population for obesity and type 2 diabetes. In this randomised controlled lifestyle intervention (RCT) addressing ME immigrants to Sweden where weight-loss was previously studied as the main outcome, as a secondary analysis we aimed to study change in Pro-NT during follow-up and if baseline Pro-NT predicted weight loss.

Registry-based randomised clinical trials: a remedy for evidence-based diabetes care?

This narrative review describes a new approach to navigation in a challenging landscape of clinical drug development in diabetes. Successful outcome studies in recent years have led to new indications and guidelines in type 2 diabetes, yet the number of clinical trials in diabetes is now declining. This is due to many environmental factors acting in concert, including the prioritisation of funding for other diseases, high costs of large randomised clinical trials, increase in regulatory requirements and limited entry of novel candidate drugs.

Genomic Impact of Whaling in North Atlantic Fin Whales.

It is generally recognized that large-scale whaling in the 19th and 20th century led to a substantial reduction of the size of many cetacean populations, particularly those of the baleen whales (Mysticeti). The impact of these operations on genomic diversity of one of the most hunted whales, the fin whale (Balaenoptera physalus), has remained largely unaddressed because of the paucity of adequate samples and the limitation of applicable techniques. Here, we have examined the effect of whaling on the North Atlantic fin whale based on genomes of 51 individuals from Icelandic waters, representing three temporally separated intervals, 1989, 2009 and 2018 and provide a reference genome for the species.

Systematic review of low-income and middle-income country perceptions of visiting surgical teams from high-income countries.

Background: The shortage of surgeons, anaesthesiologists and obstetricians in low-income and middle-income countries (LMICs) is occasionally bridged by foreign surgical teams from high-income countries on short-term visits. To advise on ethical guidelines for such activities, the aim of this study was to present LMIC stakeholders' perceptions of visiting surgical teams from high-income countries.

Method: We performed a systematic review according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines in November 2021, using standardised search terms in PubMed/Medline (National Library of Medicine), EMBASE (Elsevier), Global Health Database (EBSCO) and Global Index Medicus, and complementary hand searches in African Journals Online and Google Scholar.

Long-Term Follow-Up of Pediatric Patients with Severe Postoperative Pulmonary Hypertension After Correction of Congenital Heart Defects.

The surgical repair of congenital heart defects in children with preoperative pulmonary hypertension (PH) is to varying degree associated with the occurrence of postoperative PH. The objective of this study was to follow up children with severe postoperative PH (pulmonary arterial/aortic pressure ratio ≥ 1.0) to evaluate if pulmonary arterial pressure spontaneously normalized or needed PH-targeting therapy and to identify potential high-risk diagnoses for bad outcome.

Microelectrode clusters enable therapeutic deep brain stimulation without noticeable side-effects in a rodent model of Parkinson's disease.

Background: Deep Brain Stimulation (DBS) is an established treatment for motor symptoms in Parkinson's disease (PD). However, side effects often limit the usefulness of the treatment.

New Method: To mitigate this problem, we developed a novel cluster of ultrathin platinum-iridium microelectrodes (n = 16) embedded in a needle shaped gelatin vehicle.

Nationwide paediatric cohort study of a protective association between allergy and complicated appendicitis.

Background: In a nationwide cohort the potentially protective association between allergy and complicated appendicitis was analysed, and the influence of seasonal antigens, antihistamine treatment, and timing of allergy onset assessed.

Methods: Some 1 112 571 children born between 2000 and 2010 were followed from birth until the end of 2014. A cross-sectional analysis of appendicitis cases, with comparison of allergic versus non-allergic children for absolute risk and odds of complicated appendicitis was first undertaken.

The unidirectional phylogeny of Homo sapiens anchors the origin of modern humans in Eurasia.

Background: The Out of Africa hypothesis, OOAH, was challenged recently in an extended mtDNA analysis, PPA (Progressive Phylogenetic Analysis), that identified the African human populations as paraphyletic, a finding that contradicted the common OOAH understanding that Hss had originated in Africa and invaded Eurasia from there. The results were consistent with the molecular Out of Eurasia hypothesis, OOEH, and Eurasian palaeontology, a subject that has been largely disregarded in the discussion of OOAH.

Results: In the present study the mtDNA tree, a phylogeny based on maternal inheritance, was compared to the nuclear DNA tree of the paternally transmitted Y-chromosome haplotypes, Y-DNAs.

Growth pattern of experimental glioblastoma.

Glioblastoma multiforme (GBM) is an aggressive primary brain malignancy with a very poor prognosis. Researchers employ animal models to develop potential therapies. It is important that these models have clinical relevance.

Extracorporeal photopheresis for graft-vs-host disease: A literature review and treatment guidelines proposed by the Nordic ECP Quality Group.

Extracorporeal photopheresis (ECP) is one of the most used and established therapies for steroid-refractory graft-vs-host disease (GvHD), with a good effect to side effect profile. In this review, we present a summary of present literature and provide evidence-based treatment guidelines for ECP in GvHD. The guidelines constitute a consensus statement formed by the Nordic ECP Quality Group representing all ECP centres in the Nordic countries, and aims to facilitate harmonisation and evidence-based practice.

Coagulation tests on admission correlate with mortality and morbidity in general ICU patients: An observational study.

Background: It is well known that low platelet count on admission to intensive care units (ICU) is associated with increased mortality. However, it is unknown whether prothrombin time (PT-INR) and activated partial thromboplastin time (APTT) on admission correlate with mortality and organ failure. Therefore, the aim of this study was to investigate whether PT-INR and APTT at admission can predict outcome in the critically ill patient after adjusting for severity of illness measured with Simplified Acute Physiology Score 3 (SAPS 3).

Interpreters in healthcare: Nursing perspectives.

Purpose: This study explored nursing experiences using interpreters in primary healthcare settings.

Methods: Eight nurses in southern Sweden were subjected to semistructured interviews. The responses were divided into three categories using content analysis: interpreter influence, challenges, and strategies.

Implementation of discharge recommendations in type 1 diabetes depends on specialist nurse follow-up.

Aim: This paper presents an implementation study following previous research including a randomised controlled trial (RCT) of hospital-based home care (HBHC), referring to specialist care in a home-based setting. The aim was to evaluate whether the effects sustained when rolled out into wider practice.

Methods: In 2013-2014, 42 children newly diagnosed type 1 diabetes were included in the study at a university hospital in Sweden and followed for two years.

Linear decline of corrected platelet count increment within 24 hours after platelet transfusion in haematological patients: A prospective observational study.

Objectives: The aim of this study was to prospectively explore the detailed longitudinal development of platelet increments in patients with chemotherapy-induced bone marrow aplasia during the first 24 hours after platelet transfusion.

Methods: Patients admitted to the Haematology department during 7 months, and fulfilled inclusion criteria were divided into 4 groups: Group 1, patients with acute leukaemia; Group 2, patients after autologous stem cell transplantation (SCT); Group 3, patients after allogeneic SCT; and Group 4, patients given platelet transfusion prior to intervention. We used frequent blood sampling within 24 hours after platelet transfusion to investigate the kinetics of platelet counts following transfusion.

Outcomes of biliary atresia in the Nordic countries - a multicenter study of 158 patients during 2005-2016.

Background/purpose: Biliary atresia is the most common reason for newborn cholestasis and pediatric liver transplantation. Even after normalization of serum bilirubin after portoenterostomy, most patients require liver transplantation by adulthood due to expanding fibrosis. We addressed contemporary outcomes of biliary atresia in the Nordic countries.

Tumor Necrosis Factor Receptor 1 and 2 Are Associated With Risk of Intracerebral Hemorrhage.

Background And Purpose: Raised plasma concentrations of tumor necrosis factor receptors (TNFR) have been linked to arterial stiffness, cerebral microbleeds, and vascular events. The aim of this study was to investigate the association of circulating levels of TNFR1 and TNFR2 with risk for future intracerebral hemorrhage (ICH).

Methods: The population-based MDCS cohort (Malmö Diet and Cancer Study; n=28 449) was conducted in 1991 to 1996.

Longitudinal changes in adolescents with TOF: implications for care.

Background: We sought to identify predictors of change in right ventricular function and exercise capacity in adolescents following repair for tetralogy of Fallot.

Methods And Results: We performed a longitudinal study with serial cardiac magnetic resonance imaging and/or exercise stress tests. Patients with interim intervention on the pulmonary valve were excluded.
