Abstract
BACKGROUND Atopic dermatitis (AD) is a chronic, inflammatory, often severely itching skin disorder. It may worsen due to stress, depression, or anxiety. Calcitonin gene-related peptide (CGRP) may be involved in inflammation signaling. CGRP has also been suggested in relation to stress, depression, and anxiety. This study aimed to investigate the expression of CGRP in the skin of patients with AD. METHODS Twenty-seven adult patients with AD, characterized with clinical and psychodemographic parameters, were investigated regarding CGRP expression in skin biopsies, using an immunohistochemical technique. RESULTS The total number of CGRP-positive nerve-like fibers was found to be higher in lesional skin than in non-lesional skin. Moreover, more inflammatory cells of dendritic shape intruded into the epidermis in lesional skin compared to non-lesional skin. Keratinocytes showing expression of CGRP were also found in lesional skin. Interestingly, the number of CGRP-positive nerve-like fibers in lesional skin correlated with depressive and anxiety scores. Correlation with depressive score was also found for round CGRP-positive inflammatory cells in the epidermis. CONCLUSIONS CGRP may have a role in both the inflammatory process and distress, in AD.

Abstract
Fatty acids are produced by eukaryotes like baker's yeast Saccharomyces cerevisiae mainly using a large multifunctional type I fatty acid synthase (FASI) where seven catalytic steps and a carrier domain are shared between one or two protein subunits. While this system may offer efficiency in catalysis, only a narrow range of fatty acids are produced. Prokaryotes, chloroplasts and mitochondria rely instead on a FAS type II (FASII) where each catalytic step is carried out by a monofunctional enzyme encoded by a separate gene. FASII is more flexible and capable of producing a wider range of fatty acid structures, such as the direct production of unsaturated fatty acids. An efficient FASII in the preferred industrial organism S. cerevisiae could provide a platform for developing sustainable production of specialized fatty acids. We functionally replaced either yeast FASI genes (FAS1 or FAS2) with a FASII consisting of nine genes from Escherichia coli (acpP, acpS and fab -A, -B, -D, -F, -G, -H, -Z) as well as three from Arabidopsis thaliana (MOD1, FATA1 and FATB). The genes were expressed from an autonomously replicating multicopy vector assembled using the Yeast Pathway Kit for in-vivo assembly in yeast. Two rounds of adaptation led to a strain with a maximum growth rate (μmax) of 0.19 h-1 without exogenous fatty acids, twice the growth rate previously reported for a comparable strain. Additional copies of the MOD1 or fabH genes resulted in cultures with higher final cell densities and three times higher lipid content compared to the control.

Abstract
BACKGROUND Atopic dermatitis (AD) is a chronic inflammatory skin disorder. It is often reported to be worsened by psychological stress. OBJECTIVE To explore the role of psychological stress and related triggers in AD, and its connection to worsening of this disease, focusing on patients' perspectives. METHODS In total, 28 patients with AD were included in focus groups. Topics regarding psychological stress and psychological triggers were discussed. RESULTS The hypothesis that psychological stress may have impact on eczema and its pruritus was supported by all of the patients. Distinguishing the worsening effect of psychological stress from effects of physiological triggers, such as infection, climate and allergic factors, was claimed to be difficult by many patients. Most of the patients thought that chronic stress affected the AD more when compared to acute stress. Family problems, financial problems, work overload, school exam periods, lack of structure at work, and unforeseen events were identified as important psychological triggers. Conventional treatment/therapy with topical corticosteroids and emollients, UV light treatment, were suggested as possible treatments, as well as psychological intervention and physical exercise. CONCLUSION Psychological stress is an important factor to consider in the management of patients with AD. In particular, chronic stress tends to worsen AD. The type of stress can possibly also affect the quality of the pruritus experienced by the patients. Unforeseen events and decision making were frequently mentioned as important triggers. Furthermore, physical exercise was reported to provide beneficial effects.

Abstract
BACKGROUND Standard neuropathologic analysis of Alzheimer's brain relies on traditional fluorescence microscopy, which suffers from limited spatial resolution due to light diffraction. As a result, it fails to reveal intricate details of amyloid plaques. While electron microscopy (EM) offers higher resolution, its extensive sample preparation, involving fixation, dehydration, embedding, and sectioning, can introduce artifacts and distortions in the complex brain tissue. Moreover, EM lacks molecular specificity and has limited field of view and imaging depth. RESULTS In our study, we employed super-resolution Stimulated Emission Depletion (STED) microscopy in conjunction with the anti-human APP recombinant antibody 1C3 fluorescently labelled with DyLightTM633 (1C3-DyLight633). This combination allowed us to visualize amyloidogenic aggregates in vitro and in brain sections from a 17-month-old 3×Tg-AD mouse with sub-diffraction limited spatial resolution. Remarkably, we achieved a spatial resolution of 29 nm in vitro and 62 nm in brain tissue sections, surpassing the capabilities of conventional confocal microscopy by 5-10 times. Consequently, we could discern individual fibrils within plaques, an achievement previously only possible with EM. CONCLUSIONS The utilization of STED microscopy represents a groundbreaking advancement in the field, enabling researchers to delve into the characterization of local mechanisms that underlie Amyloid (Aβ) deposition into plaques and their subsequent clearance. This unprecedented level of detail is especially crucial for comprehending the etiology of Alzheimer's disease and developing the next generation of anti-amyloid treatments. By facilitating the evaluation of drug candidates and non-pharmacological interventions aiming to reduce amyloid burden, STED microscopy emerges as an indispensable tool for driving scientific progress in Alzheimer's research.

Abstract
PURPOSE To present a suturing technique for safe refixation of posteriorly dislocated one-piece hydrophobic acrylic intraocular lenses (IOLs). METHOD Retrospective data analysis of a series of 12 cases operated with vitrectomy, followed by IOL relocation to the retropupillary area, after which polypropylene sutures are passed through the optic-haptic junctions of the dislocated IOL and subsequently secured to the sclera. RESULTS In all cases, the IOL remained centered throughout the follow-up period (mean 10.5 months, range 3 weeks-36 months). One case was complicated by vitreous hemorrhage the first postoperative day and later cystoid macular edema. Visual acuity was not compromised at the end of follow-up. CONCLUSION The presented technique is safe and provides long-term stable refixation in cases of late posterior dislocation of a one-piece hydrophobic acrylic IOL. The risk that sutures looped around haptics will slip off the haptic is thereby avoided.

Abstract
PURPOSE To compare incidences and reasons for unplanned extra visits after phacoemulsification surgery in two unselected clinical populations with different postoperative treatment protocols. DESIGN Retrospective cohort study. METHODS We reviewed medical records of 1000 patients that underwent cataract surgery at two adjacent clinics in Sweden. At each clinic, 500 consecutive surgeries were included. Preoperatively recorded comorbidities were registered. One clinic used a non-steroidal anti-inflammatory drug (NSAID) in combination with steroids as postoperative treatment, the other used steroids in monotherapy. Main outcome was the number of patients that returned within 6 months after surgery for at least one unplanned visit. Reasons for unplanned visits were secondary outcomes. RESULTS Among patients receiving combined treatment 84 cases (16.8%) returned for at least 1 extra visit, compared with 63 cases (12.6%) in the group treated with steroids only (RR = 1.33 [95% CI 0.99-1.80, p = 0.061]). No significant differences were found regarding any underlying reasons for the visits, including cystoid macular oedema (CME). We found increased risks for CME in patients with diabetes mellitus (RR = 3.83 [95% CI 1.18-12.41, p = 0.016]) and patients with epiretinal membrane (ERM) (RR = 10.76 [95% CI 3.14-36.89, p < 0.0001]). CONCLUSIONS Postoperative anti-inflammatory treatment with NSAID in combination with steroids did not reduce need for unplanned postoperative visits or incidence of visually disturbing CME after cataract surgery compared with steroids alone. Patient groups with elevated risks for CME are of interest in future research regarding benefits and optimal use of NSAID treatment after cataract surgery.

Abstract
OBJECTIVE To assess the efficacy of inhaled ciclesonide in reducing the duration of oxygen therapy (an indicator of time to clinical improvement) among adults hospitalised with COVID-19. DESIGN Multicentre, randomised, controlled, open-label trial. SETTING 9 hospitals (3 academic hospitals and 6 non-academic hospitals) in Sweden between 1 June 2020 and 17 May 2021. PARTICIPANTS Adults hospitalised with COVID-19 and receiving oxygen therapy. INTERVENTION Inhaled ciclesonide 320 µg two times a day for 14 days versus standard care. MAIN OUTCOME MEASURES Primary outcome was duration of oxygen therapy, an indicator of time to clinical improvement. Key secondary outcome was a composite of invasive mechanical ventilation/death. RESULTS Data from 98 participants were analysed (48 receiving ciclesonide and 50 receiving standard care; median (IQR) age, 59.5 (49-67) years; 67 (68%) men). Median (IQR) duration of oxygen therapy was 5.5 (3-9) days in the ciclesonide group and 4 (2-7) days in the standard care group (HR for termination of oxygen therapy 0.73 (95% CI 0.47 to 1.11), with the upper 95% CI being compatible with a 10% relative reduction in oxygen therapy duration, corresponding to a <1 day absolute reduction in a post-hoc calculation). Three participants in each group died/received invasive mechanical ventilation (HR 0.90 (95% CI 0.15 to 5.32)). The trial was discontinued early due to slow enrolment. CONCLUSIONS In patients hospitalised with COVID-19 receiving oxygen therapy, this trial ruled out, with 0.95 confidence, a treatment effect of ciclesonide corresponding to more than a 1 day reduction in duration of oxygen therapy. Ciclesonide is unlikely to improve this outcome meaningfully. TRIAL REGISTRATION NUMBER NCT04381364.

Abstract
BACKGROUND The ProtonCare Study Group (PCSG) was formed with the purpose to develop and implement a framework for evaluation of proton beam therapy (PBT) and the related care at a novel clinic (Skandionkliniken), based on patient reported data. METHOD A logic model framework was used to describe the process of development and implementation of a structured plan for evaluation of PBT for all diagnoses based on patient reported data. After the mission for the project was determined, meetings with networks and stakeholders were facilitated by PCSG to identify assumptions, resources, challenges, activities, outputs, outcomes, and outcome indicators. RESULT This paper presents the challenges and accomplishments PCSG made so far. We describe required resources, activities, and accomplished results. The long-term outcomes that were outlined as a result of the process are two; 1) Improved knowledge about health outcomes of patients that are considered for PBT and 2) The findings will serve as a base for clinical decisions when patients are referred for PBT. CONCLUSION Using the logical model framework proved useful in planning and managing the ProtonCare project. As a result, the work of PCSG has so far resulted in long-lasting outcomes that creates a base for future evaluation of patients' perspective in radiotherapy treatment in general and in PBT especially. Our experiences can be useful for other research groups facing similar challenges. Continuing research on patients´ perspective is a central part in ongoing and future research. Collaboration, cooperation, and coordination between research groups/networks from different disciplines are a significant part of the work aiming to determine the more precise role of PBT in future treatment options.

Abstract
The bacteria Escherichia coli and the yeast Saccharomyces cerevisiae are currently the two most important organisms in synthetic biology. E. coli is almost always used for fundamental DNA manipulation, while yeast is the simplest host system for studying eukaryotic gene expression and performing large-scale DNA assembly. Yeast expression studies may also require altering the chromosomal DNA by homologous recombination. All these studies require the verification of the expected DNA sequence, and the fastest method of screening is colony PCR, which is direct PCR of DNA in cells without prior DNA purification. Colony PCR is hampered by the difficulty of releasing DNA into the PCR mix and by the presence of PCR inhibitors. We hereby present one protocol for E. coli and two protocols for S. cerevisiae differing in efficiency and complexity as well as an overview of past and possible future developments of efficient S. cerevisiae colony PCR protocols.

All patients from the Swedish National Patient Register, with a first-time diagnosis of AF between 1987 and 2018 were identified and compared with two matched controls without AF from the Total Population Register. Patients <18 years, or any previous cardiovascular disease, diabetes mellitus and renal failure at the baseline were excluded.
Results
In total 227,811 patients and 452,712 controls were included; 44.5% were women. The mean age (SD) for men was 65.5 (15) vs. 72.7 (13) in women (p<0.0001). The incidence rate for HF onset per 1000 person-years within one and five years after AF diagnosis was 77.3 (75.5–79.1) and 45.0 (44.3–45.7) in women vs. 66.5 (65.0–68.0) and 35.3 (34.8–35.9) in men, respectively. The incidence rate for HF onset increased with age in both patients with AF and controls, but was generally more pronounced in women. Women had 26% and 34% higher risk for HF onset, within five and thirty years, respectively. The highest risk for HF onset was found in women 18–34 years and 35–49 years of age, HR 24.64 (95%, confidence interval (CI) 7.59–80.0) and 8.09 (95%, CI 6.34–10.33) vs. 9.86 (95%, CI 6.81–14.27) and 6.52 (95%, CI 5.87–7.25) in equally old men. The mortality rate after HF was 42.3% and 33.1% in women and men with AF (p<0.0001).
Conclusion
In this nationwide, register-based cohort study, when compared to matched controls we found that the risk for HF onset was higher in women with AF, particularly in reproductive age, highlighting great importance of further research for prevention of HF in young women with AF but without any other cardiovascular risk factors.

Abstract
Abstract
Background
Impaired exercise capacity is a common finding among adults with congenital heart disease (CHD) and it has previously been reported that impaired exercise capacity is associated with higher risk of mortality, hospitalisation and/or transplantation. However, previous reports have been single centre with small sample sizes and composite endpoints.
Purpose
The aim of present report was to analyse the association between mortality, as primary endpoint, and aerobic exercise capacity in adults with CHD.
Methods
Data on exercise capacity from all registered test assessed with bicycle ergometer were retrieved from the Swedish Registry of Congenital Heart Disease. Percent of predicted peak workload (%Wpred) was calculated according to sex, age and height and compared to a national reference material (n=1790, 58% men).
Results
2748 adults with CHD were included (41% women). Median age was 31.7 years (range 18–80.6 years) and mean %Wpred was 77±21.0%. At a median follow-up time of 5.3 years (range 0.02–36.5 years) 135 patients were deceased (4.9%). Moderately impaired exercise capacity (50–70% Wpred) (HR 3.0, p<0.001), severely impaired exercise capacity (<50% Wpred) (HR 9.7, p<0.001), NYHA class II (HR 4.4, p<0.001) and NYHA class III–IV (HR 12.6, p<0.001) was associated with increased risk of mortality in univariable cox regression. In multi-variable Cox regression exercise capacity <50% Wpred (HR 3.0, 95% CI [1.5–5.8], p<0.001), NYHA class II (HR 2.8, 95% CI [1.6–5-1], <0.001) and NYHA class III–IV (HR 8.0, 95% CI [4.2–15.1] p<0.001) was associated with higher mortality risk adjusted for sex and diagnosis.
Conclusions
Our findings show that exercise capacity <50% and NYHA class ≥II are both associated with increased risk of mortality, regardless of diagnosis.

Abstract
Capsaicinoids are bioactive alkaloids produced by the chili pepper fruit and are known to be the most potent agonists of the human pain receptor TRPV1 (Transient Receptor Potential Cation Channel Subfamily V Member 1). They are currently produced by extraction from chili pepper fruit or by chemical synthesis. Transfer of the biosynthetic route to a microbial host could enable more efficient capsaicinoid production by fermentation and may also enable the use of synthetic biology to create a diversity of new compounds with potentially improved properties. This review summarises the current state of the art on the biosynthesis of capsaicinoid precursors in baker's yeast, Saccharomyces cerevisiae, and discusses bioengineering strategies for achieving total synthesis from sugar.

Abstract
Novel S. cerevisiae strain with tetracycline repressible ACC1 promoter. Functional expression of Y. lipolytica ACC1 in S. cerevisiae. Higher malonyl-CoA concentration achieved with Y. lipolytica ACC1 gene. S. cerevisiae Acc1p seems to interact with the heterologous Y. lipolytica Acc1p.
Malonyl-CoA is an energy-rich molecule formed by the ATP-dependent carboxylation of acetyl coenzyme A catalyzed by acetyl-CoA carboxylase. This molecule is an important precursor for many biotechnologically interesting compounds such as flavonoids, polyketides, and fatty acids. The yeast Saccharomyces cerevisiae remains one of the preferred cell factories, but has a limited capacity to produce malonyl-CoA compared to oleaginous organisms. We developed a new S. cerevisiae strain with a conditional allele of ACC1, the essential acetyl-CoA carboxylase (ACC) gene, as a tool to test heterologous genes for complementation. Yarrowia lipolytica is an oleaginous yeast with a higher capacity for lipid production than S. cerevisiae, possibly due to a higher capacity to produce malonyl-CoA. Measuring relative intracellular malonyl-CoA levels with an in-vivo biosensor confirmed that expression of Y. lipolytica ACC in S. cerevisiae leads to a higher accumulation of malonyl-CoA compared with overexpression of the native gene from an otherwise identical vector. The higher accumulation was generally accompanied by a decreased growth rate. Concomitant expression of both the homologous and heterologous ACC1 genes eliminated the growth defect, with a marginal reduction of malonyl-CoA accumulation.

Abstract
Abstract
Background
Heart failure (HF) is common in patients with atrial fibrillation (AF), and also associated with worse outcome. Consequently, it is commonly included in risk prediction models for AF, used in daily clinical praxis. However, knowledge about the association between solely AF and incidental HF is limited.
Aim
This study aims to evaluate the short and long-term risks for onset of HF in patients with AF and low cardiovascular risk profile.
Methods
All patients with first recorded hospitalization for AF in the Swedish National Patient Register, were included from the 1St January 1987 to 31st December 2018. Each patient with AF was matched by age, sex and county with two controls from the Swedish Total Population Register. Patients <18 years, or with concomitant hypertension, diabetes mellitus, coronary and periphery artery disease, previous stroke or transitory ischemic attack, cardiomyopathy, pulmonary arterial hypertension, congenital heart disease, valvular heart disease and renal failure prior or at baseline were excluded.
Results
In total 227 811 patients and 452 712 controls met the inclusion and exclusion criteria and were included in the study. The incidence rate for incidental HF per 1000 person-year within one year after AF diagnosis was 6.2 (95% CI: 4.5–8.6) among patient 18–34, increased with increasing age and was 142.8 (95% CI: 139.4–146.3) among those >80 years. Within five years the incidence rate decreased in all age categories and was 2.4 (95% CI: 1.8–3.0) among the youngest and 94.0 (95% CI: 92.4–95.6) in the oldest age group. When compared to matched controls from the general population patients with AF had a hazard ratio (HR) and CI 95% to develop HF within one year at 103.9 (46.3–233.1), 34.9 (26.5–45.9), 17.5 (15.5–19.8), 10.3 (9.6–11.1) and 6.1 (5.8–6.4) among patients aged 18–34, 35–49, 50–59, 60–69, 70–79 and >80 years, respectively.
Conclusion
Despite low cardiovascular risk profile AF still carries high risk for developing incidental HF in particular during the first observation year with increasing tendency along with increasing age. Younger patients with AF and without other cardiovascular comorbidities had more than 100 times higher relative risk to develop HF within one year when compared to matched controls.

Abstract
Abstract
Purpose
The congenital heart block is a rare but potentially serious heart conduction disease and associated with high mortality during the fetal or neonatal periods. Earlier reports are based on relatively small number of patients and there are limited data about long-term outcomes.
Methods
Data were collected from the Swedish Patient and Cause of Death register to identify all patients who were born and diagnosed with isolated congenital complete atrioventricular block (CCAVB) between 1970 and 2017. Each patient with isolated CCAVB was matched with 10 control individuals, by birth year and sex from the Total Population Register.
Results
Totally 506 patients with CCAVB and 5,050 controls included in the study (55.3% males). The incidence rate of mortality in patients with isolated CCAVB was 166 per 10.000 person-years. The overall risk of mortality in patients with isolated CCAVB was 45.4 times (95% confidence interval (CI) 32.7–62.9) higher compared to matched controls. In a subgroup investigation, the highest risk of mortality was found in patients with isolated CCAVB from birth until the age of 17 (hazard ratio 80.8, 95% CI 51.6–126.4), compared to matched controls without CCAVB.
Conclusion
In this nationwide cohort study, patients with isolated CCAVB was associated with more than 40-fold risk for overall mortality compared to age and sex matched controls. The greatest risk was found during childhood. Regularly follow-up in tertiary centers and the aware of high risk of complications may be the key to prevention.

Abstract
Background: In Sweden, 2,296,000 firearms were legally owned by private persons in 2017 and there were 150,000 persons living with a dementia diagnosis. A proportion of these persons owning a firearm may pose safety concerns. Objective: The aim was to describe firearm ownership in persons with dementia in Sweden and examine which characteristics are explaining physicians’ decision to report a person to the police as unsuitable to possess a firearm. Methods: This was a registry-based observational study. 65,717 persons with dementia registered in the Swedish Dementia Registry were included in the study. Logistic regression was used to evaluate which of the persons’ characteristics were most important in predicting the likelihood of being reported as unsuitable to possess a firearm. Relative importance of predictors was quantified using standardized coefficients (SC) and dominance analysis (DA). Results: Out of 53,384 persons with dementia, 1,823 owned a firearm and 419 were reported to the police as unsuitable owners. Firearm owners were predominantly younger, males, living alone, and without assistance of homecare. The most important predictors of being reported to the police were: living with another person (SC = 0.23), frontotemporal dementia (SC = 0.18), antipsychotics prescription (SC = 0.18), being diagnosed in a memory/cognitive clinic (SC = –0.27), female gender (SC = 0.18), mild (SC = –0.25) and moderate (SC = –0.21) dementia, and hypnotics prescription (SC = 0.17). Conclusion: Firearm owners with dementia were mostly younger males who were still living more independent lives. The decision to remove a weapon was not solely based on a diagnosis of dementia but a combination of factors was considered.

Abstract
SARS-CoV-2, the virus that causes COVID-19, spreads i. a., by respiratory droplets. The use of masks in preventing spread is controversial; masks are considered useless by many, while being mandated in some locations. Here, the effect of masking the general population on a COVID-19-like epidemic is estimated by computer simulation using three separate types of software. The main questions are whether mask use by the general population can limit the spread of SARS-CoV-2 in a country and how to identify opportunities when mask use is cost-effective and safe. To address these questions, the protective effects of different types of masks, the side-effects of masks, and avenues for improvements of masks and masking are addressed. Main results: (i) Any type of mask, even simple home-made ones, may be of value, even if the protective effect of each mask (here dubbed "one mask-protection") is low. Strict adherence to mask use does not appear to be critical but increasing one mask-protection to >50% was found to be advantageous. (ii) Masks do seem to reduce the number of new cases even if introduced at a late stage in an epidemic, but early implementation helps reduce the cumulative and total number of cases. (iii) The simulations suggest that it might be possible to eliminate a COVID-19 outbreak by widespread mask use during a limited period. There is a brief discussion of why the reported effect size of masking varies widely, and is expected to do so, because of different filtration abilities of different masks, differences in compliance and fitting, other routes of transmission, pre-existing immunity, and because a system of interconnected, disease-prone individuals has non-linear properties. A software solution to visualize infection spread is presented. The results from these simulations are encouraging, but do not necessarily represent the real-life situation, so it is suggested that clinical trials of masks are now carried out while continuously monitoring effects and side-effects. As mask use is not without risks and costs, it is suggested that governments and scientists have an important role in advising the public about the sensible use of masks.

Abstract
Abstract
Introduction
Ventricular septal defect (VSD) is one of the most common congenital heart lesions. Shunts with hemodynamic significance are usually closed early in life whereas small shunts are left without intervention. The need for late cardiac interventions in these populations is essentially unknown. The aim was to study the late cardiac interventions in adults with VSD.
Methods
The national register on congenital heart disease was searched for patients with VSD with or without associated simple cardiac defects but without complex lesions. For these patients, the last 10 years (over the age of 18) in the national patient register was searched for cardiac interventions.
Results
774 patients (mean age 39.0±14.7 years, women =50.6%), 224 (28.9%) with previous closure of VSD, were identified. The total observed time was 6920 patient years. There were 43 interventions in 41 patients (5.3%) of whom 12 had a previous closure of VSD. Twelve patients had isolated closure of VSD, 18 closure of VSD together with other cardiac surgery (one of these had repeated cardiac surgery) and 8 had only other cardiac surgery. In 4 cases, a pacemaker was implanted, of whom one together with cardiac surgery.
Conclusion
The need for cardiac interventions is relatively common in adults with a VSD, also in those without previous closure of their shunt. Our data suggests that most patients with a VSD, closed or not, should be offered periodic follow-up as approximately one out of 20 patients may encounter a complication within 10 years.

Abstract
Objective
High-sensitivity troponin T (hs-TnT) and high-sensitivity C-reactive protein (hs-CRP) may convey prognostic information in patients with aortic stenosis (AS). However, many association studies were cross-sectional, and the presence of myocardial hypertrophy and concomitant coronary artery disease (CAD) were usually not described. This study evaluated if hs-TnT and hs-CRP relate to myocardial mass, and associate with risk of and time to future surgery for AS in patients with and without concomitant CAD.
Design
In total, 336 patients who underwent surgery due to AS after participation in large population surveys were identified. Median age [interquartile range] was 59.8 [10.3] years at survey and 68.3 [12.7] years at surgery, and 48% were women. The median time between survey and surgery was 10.9 [9.3] years. Preoperatively, myocardial mass and the presence of CAD were assessed. Two matched referents were allocated for each case, and hs-TnT and hs-CRP were determined in stored plasma samples from the baseline survey. Uni- and multivariable conditional logistic regression analyses were used to estimate the risk (odds ratio [95% confidence interval]) related to one (ln) standard deviation increase in hs-TnT and hs-CRP. Time to surgery was evaluated by Kaplan-Mayer analysis and Cox regression.
Results
Hs-TnT was independently associated with surgery for AS in patients with concomitant CAD (odds ratio [95% confidence interval]) (1.22 [1.02–1.46]) and without concomitant CAD (1.39 [1.05–1.84]). Hs-CRP was not associated with surgery for AS after adjustment for traditional cardiovascular risk factors (1.06 [0.92–1.23]).
Patients with high hs-TnT levels had shorter time to surgery compared those with low levels (Figure, p<0.001) whereas hs-CRP did not associate with time to surgery. Hs-TnT levels at survey associated independently with myocardial mass at surgery (p=0.002) but not with CAD and severity of stenosis.
Conclusions
Hs-TnT – but not hs-CRP – was associated with increased risk for, and shorter time to future surgery for AS. Hs-TnT associated with myocardial mass at surgery which indicates that Hs-TnT may be used as a clinical tool and allow for identification of patients with AS who could benefit from earlier intervention.

Abstract
BACKGROUND Consolidated bioprocessing, which combines saccharolytic and fermentative abilities in a single microorganism, is receiving increased attention to decrease environmental and economic costs in lignocellulosic biorefineries. Nevertheless, the economic viability of lignocellulosic ethanol is also dependent of an efficient utilization of the hemicellulosic fraction, which contains xylose as a major component in concentrations that can reach up to 40% of the total biomass in hardwoods and agricultural residues. This major bottleneck is mainly due to the necessity of chemical/enzymatic treatments to hydrolyze hemicellulose into fermentable sugars and to the fact that xylose is not readily consumed by Saccharomyces cerevisiae-the most used organism for large-scale ethanol production. In this work, industrial S. cerevisiae strains, presenting robust traits such as thermotolerance and improved resistance to inhibitors, were evaluated as hosts for the cell-surface display of hemicellulolytic enzymes and optimized xylose assimilation, aiming at the development of whole-cell biocatalysts for consolidated bioprocessing of corn cob-derived hemicellulose. RESULTS These modifications allowed the direct production of ethanol from non-detoxified hemicellulosic liquor obtained by hydrothermal pretreatment of corn cob, reaching an ethanol titer of 11.1 g/L corresponding to a yield of 0.328 g/g of potential xylose and glucose, without the need for external hydrolytic catalysts. Also, consolidated bioprocessing of pretreated corn cob was found to be more efficient for hemicellulosic ethanol production than simultaneous saccharification and fermentation with addition of commercial hemicellulases. CONCLUSIONS These results show the potential of industrial S. cerevisiae strains for the design of whole-cell biocatalysts and paves the way for the development of more efficient consolidated bioprocesses for lignocellulosic biomass valorization, further decreasing environmental and economic costs.

Abstract
PURPOSE This study evaluated the effects of coping skills training (CST) on symptoms of depression and anxiety in cancer patients, and investigated moderators of the effects. METHODS Overall effects and intervention-related moderators were studied in meta-analyses of pooled aggregate data from 38 randomized controlled trials (RCTs). Patient-related moderators were examined using linear mixed-effect models with interaction tests on pooled individual patient data (n = 1953) from 15 of the RCTs. RESULTS CST had a statistically significant but small effect on depression (g = -0.31,95% confidence interval (CI) = -0.40;-0.22) and anxiety (g = -0.32,95%CI = -0.41;-0.24) symptoms. Effects on depression symptoms were significantly larger for interventions delivered face-to-face (p = .003), led by a psychologist (p = .02) and targeted to patients with psychological distress (p = .002). Significantly larger reductions in anxiety symptoms were found in younger patients (pinteraction < 0.025), with the largest reductions in patients <50 years (β = -0.31,95%CI = -0.44;-0.18) and no significant effects in patients ≥70 years. Effects of CST on depression (β = -0.16,95%CI = -0.25;-0.07) and anxiety (β = -0.24,95%CI = -0.33;-0.14) symptoms were significant in patients who received chemotherapy but not in patients who did not (pinteraction < 0.05). CONCLUSIONS CST significantly reduced symptoms of depression and anxiety in cancer patients, and particularly when delivered face-to-face, provided by a psychologist, targeted to patients with psychological distress, and given to patients who were younger and received chemotherapy.

Abstract
Background This multicentre, retro-prospective real-world study evaluated the visual, refractive and safety outcomes of a monofocal lens 1 year after implantation in cataract patients with or without pre-existing ocular pathologies. Methods Records from 4 centres in Germany and Sweden were reviewed to select eyes with aged-related cataracts, having undergone crystalline lens extraction by phacoemulsification and implantation of a CT ASPHINA 409 IOL. Preoperative, 1-month and 3-month postoperative data was collected retrospectively. In addition, included patients attended a prospective visit 12 months or later after surgery. The examination included: monocular uncorrected (UDVA) and corrected distance visual acuity (CDVA), subjective refraction, slit-lamp examination, optical biometry, intraocular pressure (IOP), endothelial cell count and postoperative complications. Results 282 eyes, including 94 with pre-existing ocular pathologies, were analysed. Twelve months after the surgery, 95% of eyes achieved monocular CDVA equal or better than 0.3 logMAR, mean postoperative CDVA was 0.06 ± 0.17 logMAR, and mean UDVA 0.31 ± 0.29 logMAR. Visual acuity outcomes were better in eyes with no pre-existing ocular pathologies, but both groups showed a statistically significant improvement after surgery compared with preoperative values (p ≤ 0.002). The mean sphere and spherical equivalent values also improved significantly postoperatively (p = 0.003). Overall, 62.1% of eyes had spherical equivalent within ±0.5 D and 80.9% within ±1.0 D. The IOL was stable in the capsular bag as demonstrated by tilt and decentration measurements. IOP, corneal status, and endothelial cell count values were in the normal range. Nd:YAG treatment was performed on 9.9% of the eyes. Conclusion The implantation of the monofocal CT ASPHINA 409 IOL was beneficial to restore vision in eyes with or without concomitant ocular pathology such as macular degeneration, glaucoma, Sicca syndrome, epiretinal membrane, cornea guttata, or amblyopia. Good to excellent long-term visual and refractive outcomes, and a low rate of complications in both healthy and pathological eyes were found 12 months after the surgery. Trial registration Trial registered on under the identification NCT03145103 (date of registration 9 May 2017).

Abstract
We present a literature review of surgical techniques of intraocular lens placement in eyes with insufficient capsular support, focusing on the most recent publications, together with a retrospective multicentre consecutive case series analysis of 103 eyes undergoing pars plana vitrectomy and sutureless intrascleral (SIS) fixation of a standard three-piece PCIOL. Many different approaches appear in the literature without any specific procedure achieving superior outcomes. Advantages and disadvantages vary between techniques. Common complications related to IOL fixation techniques were as follow: anterior chamber IOL: transient/permanent corneal oedema (9-66.6%), uveitis (1.1-39.3%); iris-fixated IOL: pupil ovalization (16-47.7%); and sutured scleral-fixated IOL: suture breakage/exposure (6.1-11%), vitreous haemorrhage: (5.5-16.6%). In our retrospective case series, indications for surgery were postoperative aphakia in 50 eyes (49%), IOL dislocation in 38 eyes (37%) and natural lens dislocation in 15 eyes (14%). Scleral tunnels for haptic fixation were created with (28 eyes, 27.2%) or without (75 eyes, 72.8%) 25 gauge trocar cannulas. Complications included transient hypotony (n = 20; 19.4%), corneal decompensation (n = 7; 6.7%), IOL dislocation (n = 6; 5.8%), cystoid macular oedema (n = 5; 4.8%), vitreous haemorrhage (n = 4; 3.8%) and retinal detachment (n = 4; 3.8%). Mean best corrected visual acuity improved from logMAR 0.65 to 0.36 at the final visit (p = 0.001). In conclusion, SIS fixation provides good anatomical and functional outcomes; however, complications can occur. The number of surgical approaches for IOL dislocation described in the literature indicates that optimal treatment remains to be found.

Abstract
PURPOSE To evaluate feasibility, quality of life, toxicity, and cosmetic outcome for intraoperative breast cancer brachytherapy after breast-conserving surgery using high dose rate brachytherapy. METHODS AND MATERIALS Fifty-two consecutive women, ⩾50 years old, diagnosed with a unifocal non-lobular breast cancer ⩽3 cm, N0, underwent breast-conserving surgery and sentinel node biopsy. Twenty-five women received intraoperative brachytherapy pre-pathology at primary surgery and the others post-pathology, during a second procedure. An applicator, connected to a high dose rate afterloader, was used. Two of the women were excluded due to metastases found per-operatively at a frozen section from the sentinel node. Quality of life was evaluated using two validated health questionnaires. Treatment toxicity was documented according to the LENT-SOMA scale by two oncologists. The cosmetic result was evaluated using the validated freely available software BCCT.core 2.0. RESULTS The clinical procedure worked out well logistically. Seven women received supplementary external radiotherapy due to insufficient margins and, in one case, poor adaptation of the breast parenchyma to the applicator. No serious adverse effects from irradiation were registered. The results from the health questionnaires showed no major differences compared with reference groups from the Swedish population. Only two women were registered as having a "poor" cosmetic result while a majority of the women had a "good" outcome. CONCLUSION This pilot study shows that intraoperative brachytherapy is a feasible procedure and encourages further trials evaluating its role in treatment of early breast cancer.

Abstract
UNLABELLED Death of a spouse is associated with poorer physical and mental health. We followed all married individuals, born from 1902 to 1942, during the period from 1987 to 2002, and found that widows and widowers had higher risk for hip fracture, compared with still married women and men. INTRODUCTION Spousal bereavement can lead to poorer physical and mental health. We aimed to determine whether married women and men had an elevated risk of hip fracture after death of a spouse. METHODS In a retrospective cohort study, we followed all Swedish married individuals aged 60 to 100 years (n = 1,783,035), from 1987 to 2002. Data are presented as mean with 95% confidence interval (CI). RESULTS During the follow-up period, 21,305 hip fractures among widows and 6538 hip fractures among widowers were noted. The hazard ratio (HR) for hip fracture in widows compared with married women was 1.34 (95% CI 1.31 to 1.37) and for widowers compared with married men 1.32 (95% CI 1.29 to 1.35). The HR for hip fracture in the first 6 months after death of a spouse was in widows compared with married women 1.62 (95% CI 1.53 to 1.71) and in widowers compared with married men 1.84 (95% CI 1.68 to 2.03). The elevated risk was especially prominent in young widowers in the age range 60-69 years. During the first 6 months they showed a HR of 2.76 (95% CI 1.66 to 4.58) for a hip fractvure compared with age matched married men. Widows aged 60-69 years showed a HR of 1.59 (95% CI 1.26 to 1.99) compared with age matched married women. CONCLUSION Our observation of a higher hip fracture risk in both genders in connection with the death of a spouse indicates a possible effect of bereavement on frailty.

Abstract
Nature-based interventions have been proposed to promote physical and mental health and give stress reduction. Little attention has been given to the potential of zoos for human health and wellbeing. A disadvantaged group in Sweden regarding access to nature are individuals with disabilities who consequently do not have the same access to these health benefits as other groups. To increase awareness and knowledge regarding spending time in nature and with animals, courses directed at caretakers for persons with disabilities and their users were held at Nordens Ark, a zoo in Sweden. To explore if the courses had led to increased nature activities, and if participating in the courses had affected caretakers' and their users' health and wellbeing, questionnaires and interviews for evaluating the courses were used. The results showed improved quality in nature visits because of course participation as well as positive effects for the wellbeing, sustainability for the caregivers and users in their working lives, and relationships were positively affected. The conclusion from this study is that nature and animal-based education should be more frequent to provide opportunities for a disadvantaged group to have the positive effects of nature of which most other groups have obvious access to.

Abstract
Abstract
Background
Peripheral muscle factors are presumed to be important contributors to the reduced exercise capacity in congenital heart disease (CHD), but the mechanisms are poorly understood.
Purpose
To investigate if muscle oxygenation in the calf muscle is impaired in adults with complex CHD in comparison to controls.
Method
Seventy-four adults with complex CHD (35.6±14.3 years, females n=22) were recruited from centers specialized in adult CHD. Seventy-four age and gender matched subjects were recruited as controls. Muscle oxygenation was successfully determined using near-infrared spectroscopy on the medial portion of m. gastrocnemiusin 63 patients and 67 controls. Measurements were made at rest, during venous occlusion to estimate blood flow (BF – indicated by the slope increase of total haemoglobin, HbT), at the start of isotonic unilateral heel-lifts to exhaustion, and immediately after exercise.
Results
In comparison to controls, patients had a lower muscle saturation (StO2) at rest, albeit not statistically significant, (66±17% vs. 60±19%, p=0.07), and a lower BF (0.38±0.21 vs. 0.31±0.21 HbTx3.5sec–1, p=0.07). For exercise, compared to the controls, patients had a slower desaturation rate at exercise onset (−11.7±5.8% vs. −7.7±4.3%. StO2x3.5sec–1, p<0.001), and both a slower resaturation rate (6.1±3.8% vs. 3.9±3.7% StO2x3.5sec–1, p=0.002) and a slower half recovery time (16.8±11.1 vs. 28.6±21.2 sec, p<0.001) post exercise.
Conclusion
The lower muscle oxygenation and blood flow at rest, and the slower oxygenation kinetics during exercise may give insight to the mechanism for the reduced exercise capacity commonly found in adults with complex CHD. This finding may also provide implications for design of rehabilitation programs for these patients.

Abstract
Context: Atopic dermatitis (AD) is a chronic, inflammatory, itching skin disorder, which may worsen due to stress, depression and anxiety. Tachykinins may be involved in inflammation signaling as well as they may have a role in stress, depression and anxiety. Objective: This study aimed to measure the expression of tachykinin markers, in the skin of patients with AD, and the correlation of these tachykinins with clinical and psychodemographic parameters. Materials and methods: Twenty-eight adult patients with AD were investigated regarding tachykinin expression in skin biopsies, using an immunohistochemical technique. The patients were characterized with clinical and psychodemographic parameters. Results: The number of substance P and neurokinin (NK)A positive nerve fibers, as well as NKA positive mononuclear dermal cells, was increased in lesional compared to non-lesional skin. Interestingly, the depression score and the number of dermal NK-1 receptor (R) positive cells in lesional as well as in non-lesional skin showed a correlation. Conclusion: These findings indicate an upregulation of the tachykinergic system in the inflamed skin of AD.

Abstract
Lignocellulosic hydrolysates remain one of the most abundantly used substrates for the sustainable production of second generation fuels and chemicals with Saccharomyces cerevisiae. Nevertheless, fermentation inhibitors such as acetic acid, furfural and hydroxymethylfurfural are formed during the process and can lead to slow or stuck fermentations and/or act as genotoxic agents leading to production strain genetic instability. We have developed a novel dominant deletion (DEL) cassette assay for quantification of DNA damage in both wild-type and industrial yeast strains. Using this assay, the ethanol production strain S. cerevisiae PE-2 was shown to be more resistant to hydrogen peroxide and furfural than the laboratory DEL strain RS112. Indeed, the PE-2 strain also showed a lower tendency for recombination, consistent with a more efficient DNA protection. The dominant DEL assay presented herein should prove to be a useful tool in the selection of robust yeast strains and process conditions for second generation feedstock fermentations.

Abstract
Background A systematic attempt to summarize the literature that examines working conditions and occupational health among immigrant in Europe and Canada. Methods We established inclusion criteria, searched systematically for articles included in the Medline, Embase and Social Sciences Citation Index databases in the period 2000–2016 and checked the reference lists of all included papers. Results Eighty-two studies were included in this review; 90% were cross-sectional and 80% were based on self-report. Work injuries were consistently found to be more prevalent among immigrants in studies from different countries and in studies with different designs. The prevalence of perceived discrimination or bullying was found to be consistently higher among immigrant workers than among natives. In general, however, we found that the evidence that immigrant workers are more likely to be exposed to physical or chemical hazards and poor psychosocial working conditions is very limited. A few Scandinavian studies support the idea that occupational factors may partly contribute to the higher risk of sick leave or disability pension observed among immigrants. However, the evidence for working conditions as a potential mediator of the associations between immigrant status and poor general health and mental distress was very limited. Conclusion Some indicators suggest that immigrant workers in Europe and Canada experience poorer working conditions and occupational health than do native workers. However, the ability to draw conclusions is limited by the large gaps in the available data, heterogeneity of immigrant working populations, and the lack of prospectively designed cohort studies.

Abstract
Luminance contrast sinusoidal gratings (spatial frequencies 1, 2 and 4 cycles/degree) were compared with the corresponding color contrasting patterns (along the protan, deutan and tritan axes) to see whether they demonstrated normal binocular function in humans, and distinguished between normals and persons with defective binocularity. Contrast sensitivity and transient pattern VEP latency (on-responses) were measured in normals (n = 11, median age 36, range 12-46 years) and subjects with no stereopsis (n = 6, median age 13, range 8-38 years). The normal group had significantly higher contrast sensitivity with binocular stimulation for all patterns except tritan contrast gratings of 2 and 4 c/deg. The stereo-deficient group showed no higher binocular contrast sensitivity for any pattern. Differences between groups were significant with all gratings of 4 c/deg, and also with protan and deutan contrast gratings of 2 c/deg. In the normal group, binocular VEP latency was significantly shorter than the monocular with protan contrast gratings of 2 c/deg and tritan contrast gratings of 1 and 2 c/deg. Differences between the normal and the stereo-deficient groups were significant for all color contrast patterns of 2 c/deg; and tritan contrast gratings of 1 c/deg. We conclude that color contrast sensitivity and VEP measurements are potentially useful for demonstrating binocular function, and for separating normals from stereo-blind subjects. Color contrast patterns however are less effective than the corresponding luminance contrast patterns in evoking cortical potentials.

Abstract
PURPOSE To evaluate clinical outcomes following sub-2-mm microincision cataract surgery (MICS) and intraocular lens (IOL) implantation. SETTING Five EU clinical sites. DESIGN Prospective, multicenter, open-label, single-arm, non-randomized. METHODS Preoperative assessment involved visual acuity (VA), intraocular pressure and biometry measurements. 1.4-mm wound-assisted or 1.8-mm MICS was performed. Follow-up visits were made 1 day, 1-2 weeks, 1-2 and 4-6 months after surgery. The incision size, corrected distance VA (CDVA), uncorrected distance VA, manifest refraction spherical equivalent (MRSE), refraction predictability/stability and IOL decentration were assessed. At 12-, 18-, and 24-month, long-term centration, posterior capsular opacification (PCO) and Nd:YAG capsulotomy rates were investigated. RESULTS A total of 103 eyes were implanted with the study IOL (INCISE, Bausch & Lomb), 96 of which were included in visual outcome analysis. A mean 6-month CDVA of - 0.02 logMAR (20/20 + 1) was observed and 75 eyes (79.8%) and 93 eyes (98.3%) achieved a visual acuity of at least 20/20 or 20/40. Mean MRSE was - 0.20 ± 0.60 D. Mean absolute predictive error was 0.44 ± 0.36 D, with 90.4% within 1.00 D of target. Mean total decentration was 0.35 ± 0.36 mm at 6 months and 0.32 ± 0.14 mm at 24 months (p > 0.05). 24-month evaluation of posterior capsular opacification score was 0.03 for the central area. A Nd:YAG rate of 3.4% was observed at 24 months. CONCLUSIONS The new MICS IOL provided excellent visual outcomes and was safe and effective for the sub-2-mm procedure. The MICS IOL demonstrated long-term centration, stability and a low rate of PCO development.

Abstract
Acetic acid tolerance and xylose consumption are desirable traits for yeast strains used in industrial biotechnological processes. In this work, overexpression of a weak acid stress transcriptional activator encoded by the gene HAA1 and a phosphoribosyl pyrophosphate synthetase encoded by PRS3 in a recombinant industrial Saccharomyces cerevisiae strain containing a xylose metabolic pathway was evaluated in the presence of acetic acid in xylose- or glucose-containing media. HAA1 or PRS3 overexpression resulted in superior yeast growth and higher sugar consumption capacities in the presence of 4 g/L acetic acid, and a positive synergistic effect resulted from the simultaneous overexpression of both genes. Overexpressing these genes also improved yeast adaptation to a non-detoxified hardwood hydrolysate with a high acetic acid content. Furthermore, the overexpression of HAA1 and/or PRS3 was found to increase the robustness of yeast cell wall when challenged with acetic acid stress, suggesting the involvement of the modulation of the cell wall integrity pathway. This study clearly shows HAA1 and/or, for the first time, PRS3 overexpression to play an important role in the improvement of industrial yeast tolerance towards acetic acid. The results expand the molecular toolbox and add to the current understanding of the mechanisms involved in higher acetic acid tolerance, paving the way for the further development of more efficient industrial processes.

Abstract
Objective This individual patient data (IPD) meta‐analysis aimed to evaluate the effects of psychosocial interventions (PSI) on quality of life (QoL), emotional function (EF), and social function (SF) in patients with cancer, and to study moderator effects of demographic, clinical, personal, and intervention‐related characteristics. Methods Relevant studies were identified via literature searches in 4 databases. We pooled IPD from 22 (n = 4217) of 61 eligible randomized controlled trials. Linear mixed‐effect model analyses were used to study intervention effects on the post‐intervention values of QoL, EF, and SF (z‐scores), adjusting for baseline values, age, and cancer type. We studied moderator effects by testing interactions with the intervention for demographic, clinical, personal, and intervention‐related characteristics, and conducted subsequent stratified analyses for significant moderator variables.Results: PSI significantly improved QoL (β = 0.14,95%CI = 0.06;0.21), EF (β = 0.13,95%CI = 0.05;0.20), and SF (β = 0.10,95%CI = 0.03;0.18). Significant differences in effects of different types of PSI were found, with largest effects of psychotherapy. The effects of coping skills training were moderated by age, treatment type, and targeted interventions. Effects of psychotherapy on EF may be moderated by cancer type, but these analyses were based on 2 randomized controlled trials with small sample sizes of some cancer types. Conclusions PSI significantly improved QoL, EF, and SF, with small overall effects. However, the effects differed by several demographic, clinical, personal, and intervention‐related characteristics. Our study highlights the beneficial effects of coping skills training in patients treated with chemotherapy, the importance of targeted interventions, and the need of developing interventions tailored to the specific needs of elderly patients.
