Abstract
BACKGROUND SARS-CoV-2 vaccination is recommended in patients with inborn errors of immunity (IEIs); however, little is known about immunogenicity and safety in these patients. OBJECTIVE We sought to evaluate the impact of genetic diagnosis, age, and treatment on antibody response to COVID-19 vaccine and related adverse events in a cohort of patients with IEIs. METHODS Plasma was collected from 22 health care worker controls, 81 patients with IEIs, and 2 patients with thymoma; the plasma was collected before immunization, 1 to 6 days before the second dose of mRNA vaccine, and at a median of 30 days after completion of the immunization schedule with either mRNA vaccine or a single dose of Johnson & Johnson's Janssen vaccine. Anti-spike (anti-S) and anti-nucleocapsid antibody titers were measured by using a luciferase immunoprecipitation systems method. Information on T- and B-cell counts and use of immunosuppressive drugs was extracted from medical records, and information on vaccine-associated adverse events was collected after each dose. RESULTS Anti-S antibodies were detected in 27 of 46 patients (58.7%) after 1 dose of mRNA vaccine and in 63 of 74 fully immunized patients (85.1%). A lower rate of seroconversion (7 of 11 [63.6%]) was observed in patients with autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy. Previous use of rituximab and baseline counts of less than 1000 CD3+ T cells/mL and less than 100 CD19+ B cells/mL were associated with lower anti-S IgG levels. No significant adverse events were reported. CONCLUSION Vaccinating patients with IEIs is safe, but immunogenicity is affected by certain therapies and gene defects. These data may guide the counseling of patients with IEIs regarding prevention of SARS-CoV-2 infection and the need for subsequent boosts.

Abstract
Climate change affects human health; however, there have been no large-scale, systematic efforts to quantify the heat-related human health impacts that have already occurred due to climate change. Here, we use empirical data from 732 locations in 43 countries to estimate the mortality burdens associated with the additional heat exposure that has resulted from recent human-induced warming, during the period 1991-2018. Across all study countries, we find that 37.0% (range 20.5-76.3%) of warm-season heat-related deaths can be attributed to anthropogenic climate change and that increased mortality is evident on every continent. Burdens varied geographically but were of the order of dozens to hundreds of deaths per year in many locations. Our findings support the urgent need for more ambitious mitigation and adaptation strategies to minimize the public health impacts of climate change.

Abstract
BACKGROUND Several reports have described Takotsubo syndrome (TTS) secondary to thyrotoxicosis. A complex interaction of central and peripheral catecholamines with thyroid homeostasis has been suggested. In this study, we analysed sequential thyroid hormone profiles during the acute phase of TTS. METHODS Thyrotropin (TSH), free T4 (FT4) and free T3 (FT3) concentrations were analysed at predefined time points in 32 patients presenting with TTS or acute coronary syndrome (ACS, n = 16 in each group) in a 2-year period in two German university hospitals. Data were compared to age- and sex-matched controls (10 samples, each of 16 subjects), and an unsupervised machine learning (ML) algorithm identified patterns in the hormone signature. Subjects with thyroid disease and patients receiving amiodarone were excluded from follow-up. RESULTS Among patients with TTS, FT4 concentrations were significantly higher when compared to controls or ACS. Four subjects (25%) suffered from subclinical or overt thyrotoxicosis. Two additional patients developed subclinical or overt thyrotoxicosis during stay in hospital. In four subjects (25%), FT4 concentrations were increased, despite nonsuppressed TSH concentration, representing an elevated set point of thyroid homeostasis. The thyroid hormone profile was normal in only six patients (38%) presenting with TTS. CONCLUSION Abnormal thyroid function is frequent in patients with TTS. Primary hyperthyroidism and an elevated set point of thyroid homeostasis are common in TTS, suggesting a stress-dependent endocrine response or type 2 thyroid allostasis. Thyroid function may be a worthwhile target in treating or preventing TTS.

Abstract
The Joint European Torus (JET) gamma-ray camera has been recently upgraded with the installation of new gamma-ray detectors, based on LaBr3(Ce) scintillation crystals, which add spectroscopic capability to the existing system allowing measurements with good energy resolution (5% at 0.622 MeV), a dynamic range from hundreds of keV up to about 30 MeV, and high counting rate capabilities of MCps. First gamma-ray measurements during the C38 campaign of the JET have been successfully carried out, in particular, in D-3He plasmas from three-ion ion cyclotron resonance heating experiments, where the detection of 16.4 MeV γ-rays from D + 3He → γ + 5Li reactions with the gamma-ray camera upgrade allowed determining the spatial profile of alpha particles born in D + 3He fusion reactions.

Abstract
BACKGROUND Limitations in everyday functioning are frequently reported by veterans with a history of mild traumatic brain injury (mTBI) and/or posttraumatic stress disorder (PTSD). Multiple factors are associated with functional disability among veterans, including depression, poor social support, cognition, and substance use. However, the degree to which these factors, particularly cognitive capacities, contribute to functional limitations remains unclear. METHODS We evaluated performance on tests of processing speed, executive functioning, attention, and memory as predictors of functioning on the World Health Organization Disability Assessment Scale (WHODAS) 2.0 in 288 veterans. Participants were placed in one of the following groups: PTSD-only, mTBI-only, mTBI + PTSD, and neither PTSD nor mTBI (deployed control group). Cognitive test performances were evaluated as predictors of WHODAS 2.0 functional ratings in regression models that included demographic variables and a range of mood, behavioral health, and postconcussive symptom ratings. RESULTS Multiple cognitive test performances predicted WHODAS 2.0 scores in the deployed control group, but they generally did not predict functioning in the clinical groups when accounting for demographics, mood, behavioral health, and postconcussive symptoms. CONCLUSIONS In veterans with mTBI and/or PTSD, cognitive test performances are less associated with everyday functioning than mood and postconcussive symptoms.

Abstract
Background Candida albicans causes debilitating mucosal infections in patients with inherited susceptibility to chronic mucocutaneous candidiasis (CMC), often requiring long-term azole-based treatment. Due to increasing azole resistance, alternative treatments are desirable. Acquired resistance to amphotericin B (AMB) is rare but AMB use is limited by parenteral administration and nephrotoxicity. Cochleated AMB (CAMB) is a new oral formulation of AMB and thus an attractive option for oropharyngeal candidiasis (OPC), esophageal candidiasis (EC) and vulvovaginal candidiasis (VVC). We assessed the efficacy of CAMB in mouse models of OPC and VVC and in 4 patients with azole resistant CMC manifesting as OPC, EC or VVC. Methods Act1-/- mice were infected with C. albicans in models of OPC and VVC and were treated once daily via oral gavage with CAMB or vehicle or intraperitoneal AMB-deoxycholate (AMBd) from day 1 through 4 post-infection (pi). At day 5 pi, the tongue or vaginal tissue was harvested to quantify fungal burden. Patients with azole resistant CMC enrolled in a phase 2A CAMB dose escalation study. The primary endpoint was clinical improvement at 2 weeks based on an efficacy scale, followed by optional extension for long-term suppression of CMC to assess safety and efficacy. Results CAMB-treated mice had significantly reduced tongue and vaginal tissue fungal burden compared to vehicle-treated mice, while they exhibited comparable fungal control relative to AMBd-treated mice. Among 4 CAMB-treated patients, 3 reached clinical efficacy by 2 weeks at a dose of 400 mg twice daily and one reached clinical efficacy at 200 mg twice daily. Three of 4 patients continued on the extension phase past 48 months with sustained clinical improvement of OPC and EC; patient #3 had relapse of esophageal symptoms at week 24 and was withdrawn from further study. Clinical response was not seen for onychomycosis or VVC. CAMB was safe and well-tolerated without renal toxicity. Conclusion Oral administration of CAMB in IL-17-signaling deficient mice resulted in reduced tongue and vaginal tissue fungal burden during mucosal C. albicans infections. A proof-of-concept clinical trial in humans with inherited CMC showed efficacy in OPC and EC with good tolerability and safety.

Abstract
BACKGROUND Simulation is widely used in graduate medical education. A prior survey showed that 80% of Neonatal-Perinatal Medicine (NPM) fellowship programs in the U.S. use simulation. There are multiple ways to provide simulation-based education. One such method is through intensive simulation-based education sessions held at the beginning of a training program, common called 'boot camps'. The aim of this study was to describe the use of simulation-based boot camps in NPM fellowship programs. METHODS Survey study of Accreditation Council for Graduate Medical Education (ACGME) accredited NPM fellowships in the U.S. RESULTS Fifty-nine of 98 programs (60%) responded. Thirty six (61%) participated in 1st year fellow boot camps, which focused on procedural skills and newborn resuscitation. Nearly half of programs participated in regional boot camps. Most boot camps were one or two days long. Eleven programs (19%) held 2nd or 3rd year fellow boot camps, which focused on advanced resuscitation and communication. Barriers included lack of faculty protected time (57%), funding (39%), and lack of faculty experience (31%). CONCLUSIONS A majority of ACGME accredited NPM fellowships participate in 1st year fellows' boot camps. Many participate in regional boot camps. A few programs have 2nd or 3rd year fellow boot camps. Lack of time, funding, and faculty experience were common barriers.

Abstract
Background Current oral therapeutic options for chronic mucocutaneous candidiasis (CMC) are often associated with resistance and toxicity. Amphotericin B (AMB) has broad fungicidal activity and markedly resists emergence of resistance but requires parenteral administration and monitoring for significant nephrotoxicity, which worsens with chronic treatment. Encochleated amphotericin B (CAMB) is a novel oral formulation of AMB. In animal models, CAMB demonstrates antifungal activity with similar efficacy as intraperitoneal AMB deoxycholate, but without the associated toxicity. This on-going patient volunteer study assesses the efficacy, safety, tolerability and PK of CAMB in patients with CMC who are refractory or intolerant to standard oral azole antifungals. Methods Four patients have completed the clinical protocol treatment period: 3 patients with STAT3 deficient Hyper IgE syndrome and CMC, and one patient with chronic esophageal candidiasis. Eligible patients were dose escalated (Figure 1), with option of enrolling in an extension phase. Serial plasma PK samples were collected over 24 hours over the study period, with data available from two patients (Figure 2). ![]()
![]()
Results CAMB was well tolerated by all four patients, and all are currently on the extension phase (Figure 3). There was significant improvement in clinical severity symptom scores of esophageal and oropharyngeal symptoms; CAMB01 achieved reduction in clinical symptoms by 57% (800 mg/day), CAMB02 by 85% (400 mg/day), CAMB03 50% (800 mg/day) and CAMB04 50% (800 mg/day). CAMB02 maintained higher plasma PK exposure throughout the study compared with CAMB01, a possible explanation for clinical response at a lower 400 mg/day dose. Reported adverse events were grade 1, mostly nausea and dizziness. There were no signs of liver, kidney or hematologic toxicity in any of the patients, with CAMB01 and CAMB02 receiving study drug for ~1 year. Conclusion CAMB was well tolerated in patient volunteers with long-standing symptomatic azole-resistant CMC. All four patients have met the primary endpoint of achieving 3 50% clinical response. CAMB is a promising oral therapy for patients with history of CMC, with potential use in treatment and prophylaxis of invasive fungal infections. Disclosures M.

Abstract
In this study, we investigated the feasibility of copper ore analysis on a running belt conveyor by measuring the delayed positron annihilation quanta based on the beta-decay of 62Cu, which was previously activated by a D-T, 14 MeV neutron generator. We constructed a model of a belt conveyor that measured 10 m in length to test this method. Our measurements demonstrated the feasibility of the method but practical constraints imposed by user demands and the industrial environment would make the design impractical and cost inefficient.

Abstract
The JET gamma-ray cameras have been recently upgraded within the gamma-ray camera upgrade project in support of development of JET high performance deuterium plasma scenarios and in preparation of deuterium-tritium experiments. New, dedicated detectors based on a LaBr3 crystal and silicon photo-multipliers have been developed and replaced pre-existing CsI detectors in all 19 channels. The new instrument gives opportunity of making two-dimensional gamma-ray measurements with a counting rate capability exceeding 1 MCounts/s (MCps) and energy resolution better than 5% at 1.1 MeV. The upgrade is of relevance for fast ion and runaway electron physics studies in high performance deuterium discharges and also in plasmas with tritium at neutron yields in the range up to about 5 × 1017 n/s.

Abstract
Families of Veterans with traumatic brain injury (TBI) are often faced with providing long-term informal care to their loved one. However, little is known about how their perceived health and caregiving burden contribute to their quality of life (QOL). The purpose of this descriptive study was to describe perceived health, somatic symptoms, caregiver burden, and perceived QOL and to identify the extent to which these variables are associated with QOL in female partners/spouses of Veterans with TBI. Participants completed a written questionnaire including the Patient Health Questionnaire-15, Caregiver Reaction Assessment, Quality of Life Index, and the general health subscale of the 12-Item Short Form Survey version 2. Caregivers reported moderate levels of QOL, and over a quarter of the sample reported high levels of somatic symptoms, particularly fatigue and sleep disturbance. Age, perceived general health, somatic symptoms, the five subscales of caregiver burden (self-esteem, disrupted schedule, effect on finances, lack of family support, and effect on health) predicted QOL and explained 64% of its variance (adjusted r2 = 0.64, F(8,31) = 9.59). However, only somatic symptoms and the caregiver burden subscales of self-esteem and effect on finances were significant predictors in the model. These findings have implications for development of family-centered interventions to enhance the QOL of informal caregivers of Veterans with TBI.

Abstract
An assessment study examining the relationship between sleep quality and personality style in individuals presenting to a sleep clinic with symptoms of insomnia was conducted. The protocol entailed standard clinical interviews conducted by a board certified sleep physician and licensed clinical psychologist. Participants were then assessed using a standard interview and the Millon Clinical Multi-axial Inventory III (MCMI-III) A follow-up appointment was conducted to provide interpretation and treatment recommendations from the interview and testing data. The results from a review of 210 cases are presented in terms of their sleep quality and dominant MCMI-III patterns. Preliminary multivariate analyses indicated two common profiles that correspond to the presentation of insomnia symptomology. These clusters were termed “avoidant” and “anxious” profiles, accordingly. Item content analyses were conducted via the Noteworthy Item classification in the MCMI-III manual to determine the viability of a category determined by the authors called Sleep Behavior Preoccupation. Of this sample 17% fit into the category.

Abstract
Selective area growth has been applied to fabricate a homogeneous array of GaN nanocolumns (NC) with high crystal quality. The structural and optical properties of single NCs have been investigated at the nanometer-scale by transmission electron microscopy (TEM) and highly spatially resolved cathodoluminescence (CL) spectroscopy performed in a scanning transmission electron microscope (STEM) at liquid helium temperatures. TEM cross-section analysis reveals excellent structural properties of the GaN NCs. Sporadically, isolated basal plane stacking faults (BSF) can be found resulting in a remarkably low BSF density in the almost entire NC ensemble. Both, defect-free NCs and NCs with few BSFs have been investigated. The low defect density within the NCs allows the characterization of individual BSFs, which is of high interest for studying their optical properties. Direct nanometer-scale correlation of the CL and STEM data clearly exhibits a spatial correlation of the emission at 360.6 nm (3.438 eV) with the location of basal plane stacking faults of type I1.

Abstract
Between 2004 and 2010, 189 adult patients were enrolled on the National Cancer Institute's cross-sectional chronic graft-versus-host disease (cGVHD) natural history study. Patients were evaluated by multiple disease scales and outcome measures, including the 2005 National Institutes of Health (NIH) Consensus Project cGVHD severity scores. The purpose of this study was to assess the validity of the NIH scoring variables as determinants of disease severity in severely affected patients in efforts to standardize clinician evaluation and staging of cGVHD. Out of 189 patients enrolled, 125 met the criteria for severe cGVHD on the NIH global score, 62 of whom had moderate disease, with a median of 4 (range, 1-8) involved organs. Clinician-assigned average NIH organ score and the corresponding organ scores assigned by subspecialists were highly correlated (r = 0.64). NIH global severity scores showed significant associations with nearly all functional and quality of life outcome measures, including the Lee Symptom Scale, Short Form-36 Physical Component Scale, 2-minute walk, grip strength, range of motion, and Human Activity Profile. Joint/fascia, skin, and lung involvement affected function and quality of life most significantly and showed the greatest correlation with outcome measures. The final Cox model with factors jointly predictive for survival included the time from cGVHD diagnosis (>49 versus ≤49 months, hazard ratio [HR] = 0.23; P = .0011), absolute eosinophil count at the time of NIH evaluation (0-0.5 versus >0.5 cells/μL, HR = 3.95; P = .0006), and NIH lung score (3 versus 0-2, HR = 11.02; P < .0001). These results demonstrate that NIH organs and global severity scores are reliable measures of cGVHD disease burden. The strong association with subspecialist evaluation suggests that NIH organ and global severity scores are appropriate for clinical and research assessments, and may serve as a surrogate for more complex subspecialist examinations. In this population of severely affected patients, NIH lung score is the strongest predictor of poor overall survival, both alone and after adjustment for other important factors.

Abstract
OBJECTIVE The German Methotrexate Registry has been collecting data concerning the efficacy and safety of methotrexate (MTX) treatment since 2005. The aim of this retrospective analysis is to compare oral and parenteral MTX treatment regarding efficacy and safety. METHODS Inclusion criteria were diagnosis of juvenile idiopathic arthritis, MTX treatment for at least 6 months, a consistent route of administration of MTX, and no previous or concomitant treatment with biologic agents. Efficacy was measured by the American College of Rheumatology (ACR) pediatric (Pedi) criteria. Primary outcome was efficacy defined as the number of patients reaching ACR Pedi 30 improvement criteria after 6 months of treatment. Secondary outcome criteria were the ACR Pedi 50 and Pedi 70 criteria at 6 and 12 months, respectively. Analyses were performed with the intent-to-treat population. RESULTS Of the 411 eligible patients, 259 (63%) received oral MTX and 152 (37%) received subcutaneous MTX. In both patient groups, a comparable weekly dose of MTX (0.4 mg/kg versus 0.42 mg/kg) was used, and a comparable number of patients received concomitant steroids. The primary outcome in both treatment groups was that a comparably high number of patients showed a clinical response according to the ACR Pedi 30 score after 6 months of treatment (73% versus 72%; P = 0.87). Twenty-two percent of patients with oral therapy and 27% with subcutaneous therapy had at least 1 documented adverse event. Discontinuation of treatment was observed in both groups with equal frequency, while significantly more patients with subcutaneous application discontinued MTX because of adverse events (11% versus 5%; P = 0.02). CONCLUSION In this retrospective analysis, parenteral MTX was not superior to oral administration regarding efficacy and tolerability.

Abstract
Since 2008, in order to create a collaboration directed to improve safety and consequently to reduce work injuries, we have introduced a new work methodological approach between SPRESAL (Service of Workplace Prevention and Safety) ASL 8 of Cagliari and Gruppo Sogaer, responsible for Airport Services in Cagliari. The study shows that the interaction between both parties produced encouraging results: significant decrease in injuries among operating and administrative areas employees. Accidents rate decreased from 5 to 1.8 during the observation period 2008-2010. Measures taken had increased the safety culture, a better worker behavior analisys, adherence to procedures, PPE use, more training.

Abstract
BACKGROUND AND AIMS To characterise changes in generation of cellular reactive oxygen species (ROS) in healthy males during the postprandial state, and to analyse the influence of the postprandial state on endothelial ROS generation and endothelial dysfunction. METHODS AND RESULTS Seventeen healthy subjects were recruited. Blood samples were collected in the fasting state and 2, 4, 6 and 8h after liquid-meal intake (composition: 25% fat, 55% dextromaltose and 14% protein), providing 40 gfat m(-2) body surface. Plasma lipids, apolipoproteins, glucose and insulin were measured during this period. Peripheral blood mononuclear cells (PBMCs) were isolated by density-gradient centrifugation. The influence of postprandial state on intracellular ROS generation was measured by two different methods in PBMCs and in a human immortalised endothelial cell line (ECV 304). Artery flow-mediated vasodilation (FMD) was used to evaluate the endothelial function, and oxygen consumption by PBMCs was measured. Reduced ROS generation was observed in all methods and cells during the postprandial period. FMD was impaired 8h after meal intake (23±6 vs. 13±2, P<0.05 vs. baseline). The consumption of oxygen was reduced in PBMCs (-14% into 2h, P<0.05 vs. baseline and -27% after 4h, P<0.01 vs. baseline). ROS generation was correlated with plasma lipids, insulin, apolipoproteins and oxygen consumption. CONCLUSIONS In contrast to the previously reported elevation of postprandial oxidative stress, this study shows reduced ROS generation in PBMCs and in ECV 304. Data obtained in both cellular models suggest the existence of a protective response against plasma postprandial oxidative stress.

Abstract
(Ga,Mn)N nanowires were grown by plasma-assisted molecular beam epitaxy on p-type Si(111) substrates. Chemical composition and elemental distribution of single nanowires were analyzed by energy dispersive X-ray spectroscopy revealing an inhomogeneous Mn distribution decreasing from the surface of the nanowires toward the inner core region. The average Mn concentration within the nanowires is found to be below 1%. High-resolution transmission electron microscopy shows the presence of planar defects perpendicular to the growth direction in undoped and Mn-doped GaN nanowires. The density of planar defects dramatically increases under Mn supply.
