Abstract
Analysis was conducted to compare levodopa/carbidopa pharmacokinetics and drug-related material in plasma of healthy participants after receiving a continuous infusion of Levodopa/Carbidopa Intestinal Gel (LCIG) to a continuous subcutaneous infusion of foslevodopa/foscarbidopa. Study samples were from a randomized, open-label, 2-period crossover study in 20 healthy participants. Participants received either 24-h foslevodopa/foscarbidopa SC infusion to the abdomen or LCIG delivered for 24 h to the jejunum through a nasogastric tube with jejunal extension. Serial blood samples were collected for PK. Comparability of the LD PK parameters between the two treatment regimens was determined. Selected plasma samples were pooled per treatment group and per time point for metabolite profiling. LC-MSn was performed using high-resolution mass spectrometry to identify drug-related material across the dosing regimens and time points. The LD PK parameter central values and 90% confidence intervals following the foslevodopa/foscarbidopa subcutaneous infusion were between 0.8 and 1.25 relative to the LCIG infusion. With LCIG administration, LD, CD, 3-OMD, DHPA, DOPAC, and vanillacetic acid were identified in plasma at early and late time points (0.75 and 24 h); the metabolic profile after administration of foslevodopa/foscarbidopa demonstrated the same drug-related compounds with the exception of the administered foslevodopa. 3-OMD and vanillacetic acid levels increased over time in both treatment regimens. Relative quantification of LC-MS peak areas showed no major differences in the metabolite profiles. These results indicate that neither the addition of monophosphate prodrug moieties nor SC administration affects the circulating metabolite profile of foslevodopa/foscarbidopa compared to LCIG.

Abstract
The optimization of an allosteric fragment, discovered by differential scanning fluorimetry, to an in vivo MAT2a tool inhibitor is discussed. The structure-based drug discovery approach, aided by relative binding free energy calculations, resulted in AZ'9567 (21), a potent inhibitor in vitro with excellent preclinical pharmacokinetic properties. This tool showed a selective antiproliferative effect on methylthioadenosine phosphorylase (MTAP) KO cells, both in vitro and in vivo, providing further evidence to support the utility of MAT2a inhibitors as potential anticancer therapies for MTAP-deficient tumors.

Abstract
Tamoxifen is a selective estrogen receptor modulator used mainly for the treatment of breast cancer. Based on the case reports and studies performed to date on the retinal toxicity of tamoxifen, retinopathy appears to occur in as many as 12% of patients taking 20 mg tamoxifen a day for over 2 years. Of this 12%, as many as half develop symptomatic changes in visual acuity. Retinal changes consist primarily of crystalline deposits, cystoid macular edema, hyperreflective deposits in the inner retinal layers, and telangiectasia. Tamoxifen retinopathy is currently managed by discontinuing tamoxifen therapy as the cancer prognosis permits; however, discontinuing therapy demonstrates little to no improvement in visual acuity once visual changes have taken place. Intravitreal injections of steroids or antivascular endothelial growth factor therapy have been performed, but require further studying before conclusions can be made. Until then, optical coherence tomography screening for retinal changes should be performed every 6 months for patients who have been on tamoxifen therapy for 2 years or more. This way, patients can become aware of retinal changes, and their physicians can consider adjusting tamoxifen therapy before they risk developing changes in visual acuity.

Abstract
Introduction Sarcopenia is defined as a decline in muscle function as well as muscle mass. Sarcopenia itself and sarcopenic obesity, defined as sarcopenia in obese patients, have been used as surrogates for a worse prognosis in colorectal cancer. This review aims to determine if there is evidence for sarcopenia as a prognostic parameter in colorectal liver metastases (CRLM). Methods PubMed, Embase, Cochrane Central, Web of Science, SCOPUS, and CINAHL databases were searched for articles that were selected in accordance with the PRISMA guidelines. The primary outcomes were overall survival (OS) and disease-free survival (DFS). A random effects meta-analysis was conducted. Results After eliminating duplicates and screening abstracts (n = 111), 949 studies were screened, and 33 publications met the inclusion criteria. Of them, 15 were selected after close paper review, and 10 were incorporated into the meta-analysis, which comprised 825 patients. No significant influence of sarcopenia for OS (odds ratio (OR), 2.802 (95% confidence interval (CI), 1.094-1.11); p = 0.4) or DFS (OR, 1.203 (95% CI, 1.162-1.208); p = 0.5) was found, although a trend was defined toward sarcopenia. Sarcopenia significantly influenced postoperative complication rates (OR, 7.905 (95% CI, 1.876-3.32); p = 0.001) in two studies where data were available. Conclusion Existing evidence on the influence of sarcopenia on postoperative OS as well as DFS in patients undergoing resection for CRLM exists. We were not able to confirm that sarcopenic patients have a significantly worse OS and DFS in our analysis, although a trend toward this hypothesis was visible. Sarcopenia seems to influence complication rates but prospective studies are needed.

Abstract
BACKGROUND In locally advanced breast cancer, axillary lymph node dissection remains a pivotal component of surgical therapy. Apart from this, it has been mostly replaced by sentinel node biopsy. Complications after axillary dissection include wound infection, neuropathy, lymphedema and-most frequently-seroma. In this retrospective multi-centre study, we compared the use of LigaSureTM with monopolar electrocautery regarding perioperative outcome. METHODS A retrospective data analysis from female breast cancer patients who underwent axillary dissection at two breast centres in Austria that are using two different surgical techniques was performed for this study. We compared the rate of complications and re-operations, length of hospital stay, time to drain removal, total drain fluid, seroma formation after drain removal, number of seroma aspirations and total seroma fluid. RESULTS Seventy one female patients with a median age of 63 (30-83) were included in this study. In 35 patients LigaSureTM and in 36 monopolar cautery was used for axillary dissection. There was no significant difference regarding intraoperative complications and rate of re-operations between the two groups (2.9 vs. 5.6%; p = 1 and 2.9 vs. 13.9%; p = 0.199). The time to drain removal and the length of hospital stay was similar in both groups. A significant difference in the occurence of postoperative wound infection could also not be shown. However, we found a significantly smaller total drain fluid in the LigaSureTM-group compared to the cautery-group (364.6 ml vs. 643.4 ml; p = 0.004). Seroma formation after drain removal was more frequent in the LigaSureTM-group (68.6 vs. 41.7%; p = 0.032) with a higher number of outpatient seroma aspirations (2.0 vs. 0.9; p = 0.005). CONCLUSION LigaSureTM and monopolar cautery provide equivalent techniques in axillary lymph node dissection with comparable postoperative outcomes.

Abstract
Costimulatory CD40 plays an essential role in autoimmune diseases, including experimental autoimmune encephalomyelitis (EAE), a murine model of human multiple sclerosis (MS). However, how CD40 drives autoimmune disease pathogenesis is not well defined. Here, we used a conditional knockout approach to determine how CD40 orchestrates a CNS autoimmune disease induced by recombinant human myelin oligodendrocyte glycoprotein (rhMOG). We found that deletion of CD40 in either dendritic cells (DCs) or B cells profoundly reduced EAE disease pathogenesis. Mechanistically, CD40 expression on DCs was required for priming pathogenic Th cells in peripheral draining lymph nodes and promoting their appearance in the CNS. By contrast, B cell CD40 was essential for class-switched MOG-specific Ab production, which played a crucial role in disease pathogenesis. In fact, passive transfer of MOG-immune serum or IgG into mice lacking CD40 on B cells but not DCs reconstituted autoimmune disease, which was associated with inundation of the spinal cord parenchyma by Ig and complement. These data demonstrate that CD40 supports distinct effector programs in B cells and DCs that converge to drive a CNS autoimmune disease and identify targets for intervention.

Abstract
Canine Diabetes (CD) is identical to human T1DM. Helper T cells expressing the CD40 receptor (TH40) are prominent in human T1DM. TH40 cell expansions occur regardless of HLA haplotype or auto-antibody status and remain elevated throughout disease. TH40 cells from T1DM respond to human islets, TH40 from healthy controls do not. At a Veterinary Hospital 6 female and 2 male dogs that met clinical criteria for T1DM were recruited. Physical exam, blood panels and CBC were done. Dogs were dosed with a OPT501 a drug targeting CD40 mediated inflammation by IV infusion. Doses were 2 and later 4 mg/kg, given on days 1, 4, 7, then weekly for 8 weeks. Diabetic dogs had significantly elevated TH40 numbers compared to non-diabetic dogs (p < 0. 0001). OPT501 reduced TH40 cell numbers to normal, following which insulin requirements reduced on average by 75% and up to 90%. The canine equivalent of HbA1c reduced 40.2% on average; 3 subjects were normal range. Daily blood glucose reduced significantly, 3 subjects maintained normal glucose levels. Time-in-range (TIR) increased to up to 90%, from a previous 10%. Increased c - peptide levels were universally detected after 8 weeks of treatment.

Abstract
The utility of zebrafish is becoming more frequent due to lower costs and high similarities to humans. Zebrafish larvae are attractive subjects for drug screening and drug metabolism research. However, obtaining good quality zebrafish larvae sections for batch samples at designated planes, angles, and locations for comparison purposes is a challenging task. We report here the optimization of fresh frozen zebrafish larvae sectioning for mass spectrometry imaging. We utilized the gelatin solutions that were created at two different temperatures (50 and 85 °C) as embedding media. Gelatin-50 (gelatin created under 50 °C, solid gel under room temperature) was used to make a larvae-shaped mold and gelatin-85 (gelatin created under 85 °C, liquid under room temperature) was used to embed the larvae. H&E staining of sections shows well-preserved morphology and minimal histological interference. More importantly, the position of the larvae was well controlled resulting in more consistent sectioning of the larvae.

Abstract
BACKGROUND AND AIMS The aim of this study was to evaluate the safety and effectiveness of Hemospray (Cook Medical, Winston-Salem, NC, USA), a hemostatic powder, as monotherapy for active peptic ulcer bleeding. METHODS In this prospective, multicenter, single-arm study, patients with Forrest Ia or Ib peptic ulcers underwent endoscopic application of Hemospray as treatment of first intent. Effectiveness endpoints were successful hemostasis at the end of the index endoscopy, recurrent bleeding within 72 hours and from 72 hours to 30 days, adverse events requiring reintervention or resulting in morbidity or mortality, and 30-day mortality. RESULTS Hemospray was successfully administered in 98.5% of patients (66/67). Hemostasis was achieved at the index endoscopy in 90.9% of patients (60/66) with Hemospray alone and in an additional 4 patients treated with additional modalities, yielding an overall hemostasis rate of 97.0% (64/66). Rebleeding occurred in 13.3% of patients (8/60), 5 within 72 hours and 3 between 72 hours and 30 days. Two cases of perforation and 2 patient deaths occurred during the study, but none of these cases or any other adverse events were attributed to the use of Hemospray. The rate of early rebleeding was significantly higher in patients with Forrest Ia ulcers compared with patients with Forrest Ib ulcers. Higher rates of early bleeding in patients with Forrest Ia ulcers is consistent with results from studies where Hemospray was used as rescue after failure of conventional methods. CONCLUSIONS Hemospray is an effective initial treatment for patients with active peptic ulcer bleeding, but care should be taken to monitor for recurrent bleeding.

Abstract
OBJECTIVE To investigate the role of Ca2+/calmodulin-dependent protein kinase 2 (CaMKK2) in post-traumatic osteoarthritis (PTOA). METHODS Destabilization of the medial meniscus (DMM) or sham surgeries were performed on 10-week-old male wild-type (WT) and Camkk2-/- mice. Half of the DMM-WT mice and all other cohorts (n = 6/group) received tri-weekly intraperitoneal (i.p.) injections of saline whereas the remaining DMM-WT mice (n = 6/group) received i.p. injections of the CaMKK2 inhibitor STO-609 (0.033 mg/kg body weight) thrice a week. Study was terminated at 8- or 12-weeks post-surgery, and knee joints processed for microcomputed tomography imaging followed by histology and immunohistochemistry. Primary articular chondrocytes were isolated from knee joints of 4-6-day-old WT and Camkk2-/- mice, and treated with 10 ng/ml interleukin-1β (IL)-1β for 24 or 48 h to investigate gene and protein expression. RESULTS CaMKK2 levels and activity became elevated in articular chondrocytes following IL-1β treatment or DMM surgery. Inhibition or absence of CaMKK2 protected against DMM-associated destruction of the cartilage, subchondral bone alterations and synovial inflammation. When challenged with IL-1β, chondrocytes lacking CaMKK2 displayed attenuated inflammation, cartilage catabolism, and resistance to suppression of matrix synthesis. IL-1β-treated CaMKK2-null chondrocytes displayed decreased IL-6 production, activation of signal transducer and activator of transcription 3 (Stat3) and matrix metalloproteinase 13 (MMP13), indicating a potential mechanism for the regulation of inflammatory responses in chondrocytes by CaMKK2. CONCLUSIONS Our findings reveal a novel function for CaMKK2 in chondrocytes and highlight the potential for its inhibition as an innovative therapeutic strategy in the prevention of PTOA.

Abstract
BACKGROUND Mortality and delirium in critically ill patients are affected by the provided analgesics and sedatives. The deeper the sedation and the higher the dose of analgesics applied, the more difficult it is to assess pain and the depth of sedation. Therefore, instrumental measurement methods, such as the measurement of the stimulus threshold of the nociceptive flexion reflex (NFRT), are becoming increasingly more important. OBJECTIVE The aim of the present study is to investigate a potential association between the level of the nociceptive flexion reflex, mortality, and the occurrence of delirium. MATERIAL AND METHODS By retrospectively analyzing a pilot data set of 57 ICU patients from the interdisciplinary surgical ICU of Ulm University Hospital surveyed between 11/2018 and 03/2020, a possible association between the NFRT, mortality, and the occurrence of delirium was calculated in an adjusted logistic regression model. Depending on the cut-off value, the stimulus threshold corridors result in the following comparison pairs: < 20 mA vs. 20-40 mA/20-50 mA/20-60 mA, > 40 mA vs. 20-40 mA, > 50 mA vs. 20-50 mA and > 60 mA vs. 20-60 mA. Results are presented as odds ratios (OR) adjusted for age, sex, height, TISS-28, SAPS II, RASS, BPS, and applied analgesics. Pain assessment was performed, in addition to the Behavioral Pain scale, ≥ 3 times daily by measuring NFRT. RESULTS A statistically nonsignificant tendency for an increase in mortality incidence occurred with an NFRT > 50 mA, versus a stimulus threshold corridor of 20-50 mA (OR 3.3, CI: 0.89-12.43, p = 0.07). A trend toward a reduction in delirium incidence occurred at an NFRT < 20 mA, versus a stimulus threshold corridor of 20-40 mA (OR 0.40, CI: 0.18-0.92, p = 0.03). CONCLUSION Based on the level of the NFRT, no recommendation can be made at this point to adjust the analgesic regimen of critically ill patients, who are unable to communicate. The observation of a tendency towards an increase in mortality at high stimulus thresholds or a reduction in the occurrence of delirium at low stimulus thresholds of the NFRT must be verified in standardized studies.

Abstract
OBJECTIVE During the COVID-19 pandemic, the number of patients presenting in hospitals because of emergency conditions decreased. Radiology is thus confronted with the effects of the pandemic. The aim of this study was to use natural language processing (NLP) to automatically analyze the number and distribution of fractures during the pandemic and in the 5 years before the pandemic. MATERIALS AND METHODS We used a pre-trained commercially available NLP engine to automatically categorize 5397 radiological reports of radiographs (hand/wrist, elbow, shoulder, ankle, knee, pelvis/hip) within a 6-week period from March to April in 2015-2020 into "fracture affirmed" or "fracture not affirmed." The NLP engine achieved an F1 score of 0.81 compared to human annotators. RESULTS In 2020, we found a significant decrease of fractures in general (p < 0.001); the average number of fractures in 2015-2019 was 295, whereas it was 233 in 2020. In children and adolescents (p < 0.001), and in adults up to 65 years (p = 0.006), significantly fewer fractures were reported in 2020. The number of fractures in the elderly did not change (p = 0.15). The number of hand/wrist fractures (p < 0.001) and fractures of the elbow (p < 0.001) was significantly lower in 2020 compared with the average in the years 2015-2019. CONCLUSION NLP can be used to identify relevant changes in the number of pathologies as shown here for the use case fracture detection. This may trigger root cause analysis and enable automated real-time monitoring in radiology.

Abstract
BACKGROUND In the last few years, there has been a growing interest in the role of gut microbiota in the development of obesity and its complications. OBJECTIVES In this study, we tested the following hypotheses: 1) lean youth and youth with obesity experience a different capability of their gut microbiota to ferment carbohydrates and produce acetate; and 2) colonic acetate may serve as a substrate for hepatic de novo lipogenesis (DNL). METHODS Nineteen lean youth [mean ± SE BMI (in kg/m2): 21.8 ± 0.521] and 19 youth with obesity (BMI: 35.7 ± 1.66), ages 15-21 y, frequency-matched by age and sex, underwent a fasting 10-h sodium [d3]-acetate intravenous infusion to determine the rate of appearance of acetate (Raacet) into the peripheral circulation before and after an oral dose of 20 g of lactulose. Pre- and post-lactulose Raacet values were determined at a quasi-steady state and changes between groups were compared using a quantile regression model. Acetate-derived hepatic DNL was measured in 11 subjects (6 youth with obesity) and its association with Raacet was assessed using Spearman correlation. RESULTS Mean ± SE Raacet was not different before lactulose ingestion between the 2 groups (7.69 ± 1.02 μmol · kg-1 · min-1 in lean youth and 7.40 ± 1.73 μmol · kg-1 · min-1 in youth with obesity, P = 0.343). The increase in mean ± SE Raacet after lactulose ingestion was greater in lean youth than in youth with obesity (14.7 ± 2.33 μmol · kg-1 · min-1 and 9.29 ± 1.44 μmol · kg-1 · min-1, respectively, P = 0.001). DNL correlated with Raacet, calculated as changes from the pre- to the post-lactulose steady state (ρ = 0.621; P = 0.046). CONCLUSIONS These data suggest that youth with obesity ferment lactulose to a lesser degree than youth without obesity and that colonic acetate serves as a substrate for hepatic DNL.This trial was registered at clinicaltrials.gov as NCT03454828.

Abstract
In this paper, we explore how science textbook authors reconciled their personal hopes with disciplinary and societal demands in their writing. Using a qualitative narrative storytelling research method, we interviewed four Canadian science textbook authors about their hopes and the challenges they encountered in their writing. To understand their hopes, we distinguished between transcendent and immanent hopes, a distinction that was motivated by our initial interpretation of the interviews. All the authors described difficulties in addressing social issues in their science textbook writing in the processes of authorization and resistance from science teachers, which located their hope in the transcendent domain. Yet, their immanent hopes with the agency also emerged in the discussion of teachers' actions to develop and use alternative texts that engage with local socio-environmental issues, rather than on textbook content innovations. This suggests the need to support developing and experienced teachers as professionals in their decision-making about pedagogy and to equip them to critically examine available resources and write and share quality resources.

ZusammenfassungDie neue ATS/ERS/ESCMID/IDSA-Leitlinie beantwortet 22 PICO-Fragen zur Behandlung von Erkrankungen der Lunge durch Mycobacterium avium-Komplex (MAC), M. kansasii, M. xenopi und M. abscessus.
Allgemeines Insbesondere bei Patienten mit mikroskopischem Nachweis säurefester Stäbchen im Sputum oder kavernöser Verlaufsform sollte der Behandlungsbeginn nicht verzögert werden. Die Behandlung sollte auf einer speziesspezifischen Resistenztestung (entsprechend den CLSI-Guidelines) basieren.
MAC-Lungenerkrankung Die Therapie erfolgt hier mit mindestens 3 Medikamenten inklusive einem Makrolid (eher Azithromycin als Clarithromycin) und Ethambutol. Für Patienten mit kavitärer, mit ausgeprägter nodulär-bronchiektatischer Erkrankung oder mit Makrolid-Resistenz wird zur täglichen oralen Therapie eine additive Gabe von parenteralem Amikacin oder Streptomycin empfohlen. Liposomal verkapseltes inhalatives Amikacin wird bei Therapieversagen empfohlen. Patienten mit nodulär-bronchiektatischer Erkrankungsmanifestation sollten eine orale Makrolid-basierte Therapie, die – je nach Ausmaß – 3 ×/Woche gegeben werden kann, erhalten. Als Dauer werden 12 Monate nach Konversion der Sputumkultur empfohlen.
M. kansasii-Lungenerkrankung Empfohlen ist die Dreifachkombination aus Rifampicin, Ethambutol und Makrolid (oder Isoniazid ) für mindestens 12 Monate. Bei Rifampicin-Resistenz oder -unverträglichkeit wird Moxifloxacin als Ersatz empfohlen.
M. xenopi-Lungenerkrankung Empfohlen ist die Dreifachkombination aus Rifampicin, Ethambutol und Makrolid (oder Moxifloxacin) für mindestens 12 Monate nach Konversion der Sputumkultur. Es wird empfohlen, bei Patienten mit kavernöser Verlaufsform zumindest parenterales Amikacin zu addieren und Experten zu konsultieren.
M. abscessus-Lungenerkrankung Mindestens 3 Medikamente werden zur Therapie empfohlen. Die Substanzauswahl sollte auf einer In-vitro-Resistenztestung basieren. Makrolide sind die Grundlage, sollten aber bei Stämmen mit induzierbarer Makrolidresistenz nicht mitgerechnet werden. Zur Therapiedauer werden aufgrund fehlender Daten keine expliziten Empfehlungen ausgesprochen, eine Konsultation von Experten wird empfohlen.

Abstract
PATIENT HISTORY AND CLINICAL FINDINGS A 46-year old construction worker presented at the emergency department with two orthostatic syncopes. The patient complained of prolonged fever and coughs for 7 days which had not improved after oral treatment with sultamicillin for 5 days, prescribed by the patient's general practitioner. Physical examination showed high blood pressure due to previously known hypertension. Other vital signs without pathological findings. Pulmonary auscultation showed basal soft crackling noises of the left lung. FINDINGS AND DIAGNOSIS Laboratory examination showed increased values for LDH, pro-BNP and CRP and normal values for leucocytes and procalcitonin. Conventional X-Ray of the chest showed bipulmonal lateral atypical infiltrates. After the first PCR turned in negative another PCR-analysis for SARS-CoV-2 of a deep oral swab-sample was performed since the clinical, laboratory and radiological findings were typical for COVID-19. Again, SARS-CoV-2-RNA was not detected. A CT-scan of the chest showed bipulmonal lateral ground-glass attenuation, again typical for COVID-19 associated pneumonia. After a third attempt for a PCR-analysis of a deep oral swab-sample was negative, analysis of a sputum was performed which finally confirmed the diagnosis of COVID-19 associated pneumonia. THERAPY AND COURSE OF EVENTS The patient was admitted for evaluation of syncopes and suspect of COVID-19 associated pneumonia. The patient was prophylactically isolated while the result of SARS-CoV-2-PCR from a deep oral swab was pending. Suspecting a possible secondary bacterial infection at the beginning, intravenous antibiotic treatment with ampicillin/sulbactam was initiated. While further examinations showed no indication for bacterial infection, antibiotics were discontinued after 3 days. Due to clinical recovery antiviral therapy was not performed after confirming the diagnosis. The patient was discharged 17 days after onset of first symptoms without any requirements for further isolation. CONCLUSION This casuistic describes a case of COVID-19 associated pneumonia presenting with typical clinical features, laboratory and radiological findings. Detection of viral RNA was not successful from deep oral swab-samples despite repeated attempts. Finally, PCR-analysis of sputum confirmed the diagnosis. Analysis of deeper airway samples (sputum, bronchoalveolar lavage, tracheal secretions) or stool for SARS-CoV-2 should be performed in cases of evident clinical suspicion of COVID-19 and negative PCR results from deep oral swabs.

Abstract
Occupational ergonomics in healthcare is an increasing challenge we have to handle in the near future. Physical assistive systems, so-called exoskeletons, are promising solutions to prevent work-related musculoskeletal disorders (WMSDs). Manual handling like pushing, pulling, holding and lifting during healthcare activities require practical and biomechanical effective assistive devices. In this article, a musculoskeletal-model-based development of an assistive exoskeleton is described for manual patient transfer in the surgery waiting room. For that purpose, kinematic data collected with an experimental set-up reproducing real patient transfer conditions are first used to define the kinetic boundary conditions for the model-based development approach. Model-based analysis reveals significant relief potential in the lower back and shoulder area of the musculoskeletal apparatus. This is corroborated by subjective feedback collected during measurements with real surgery assistants. A shoulder–arm exoskeleton design is then proposed, optimized and evaluated within the same simulation framework. The presented results illustrate the potential for the proposed design to reduce significantly joint compressions and muscle activities in the shoulder complex in the considered patient transfer scenarios.

Abstract
Abstract
A collaborative study was performed in 18 laboratories to validate use of Rappaport-Vassiliadis (RV) medium in the standard culture method for recovery of Salmonella spp. from raw, highly contaminated foods and poultry feed. RV medium made from its individual ingredients and incubated at 42�C was compared with selenite cystine (SC) broth incubated at 35�C and tetrathionate (TT) broth incubated at 35� and 43�C for effectiveness in recovery of Salmonella spp. Four artificially contaminated foods (oysters, frog legs, mushrooms, and shrimp) and poultry feed and one naturally contaminated food (chicken) were analyzed. The artificially contaminated foods were inoculated with single serovars of Salmonella at target levels of 0.04 colony-forming units (CFU)/g for the low level and 0.4 CFU/g for the high level. For analysis of 1125 test portions, RV medium (42�C) recovered Salmonellairom 409 test portions; TT (43�C), from 368 test portions; TT (35�C), from 310 test portions; and SC (35�C), from 334 test portions. Overall, RV medium was comparable with or better than other selective enrichments for recovery of Salmonella from the foods in this study, except mushrooms. From mushrooms, SC broth (35�C) recovered more positive test portions than did RV medium (42�C) and TT broth (43�C). The method for detection of Salmonella in raw, highly contaminated foods and

Abstract
UNLABELLED Fragility fractures of the pelvis (FFP) are an increasing entity among elderly persons. Characteristics are different from high-energy pelvic trauma. Little is known about the natural course of FFP in conservative and after operative treatment. MATERIALS AND METHODS Medical charts and radiologic data of 148 patients with an FFP, who were admitted in a 3-year period, were analysed retrospectively. Incidence and characteristics of fracture progression (FP) were noted. RESULTS Patients presenting early after a traumatic event had more often non-displaced fractures, fractures with lower FFP Type classification and were more frequently treated conservatively. FP was observed in 21 cases (14.2%), twenty times after conservative and once after operative treatment. FP under conservative treatment occurred in female patients only. Patients with FP were younger than patients without. FP occurred in all fracture types, most frequently in FFP Type I. A second CT scan was positive for FP in 39.2% of patients with prolonged pain or restricted mobility. CONCLUSION FP is a real phenomenon, occurring in a minority of FFP patients. Female patients are at highest risk. Repeated CT scan is positive in nearly 40% of patients with continuing pain or restricted mobility. Operative treatment is a good preventive measure of FP as FP does only exceptionally occur after operative fixation of FFP.

Abstract
Landslides are common in high-latitude forest ecosystems that have developed on permafrost. The most vulnerable areas in the permafrost territories of Siberia occur on the south-facing slopes of northern rivers, where they are observed on about 20% of the total area of river slopes. Landslide disturbances will likely increase with climate change especially due to increasing summer-autumn precipitation. These processes are the most destructive natural disturbance agent and lead to the complete removal of pre-slide forest ecosystems (vegetation cover and soil). To evaluate postsliding ecosystem succession, we undertook integrated ecological research at landslides of different age classes along the Nizhnyaya Tunguska River and the Kochechum River (Tura, Krasnoyarsk region, Russia). Just after the event (at the one-year-old site), we registered a drop in soil respiration, a threefold lower microbial respiration rate, and a fourfold smaller mineral soil carbon and nitrogen stock at bare soil (melkozem) plots at the middle location of the site as compared with the non-affected control site. The recovery of disturbed areas began with the re-establishment of plant cover and the following accumulation of an organic soil layer. During the 35-year succession (L1972), the accumulated layer (O-layer) at the oldest site contained similar C- and N stocks to those found at the control sites. However, the mineral soil C- and N stocks and the microbial biomass - even of the oldest landslide area - did not reach the value of these parameters in control plots. Later, the soil respiration level and the eco-physiological status of soil microbiota also recovered due to these changes. This study demonstrates that the recovery after landslides in permafrost forests takes several decades. In addition, the degradation of permafrost due to landslides clearly hinders the accumulation of soil organic matter in the mineral soil.

Abstract
Background Serious pediatric infections are treated safely with outpatient parenteral or prolonged oral antibiotic therapy (OPAT). The OPAT delivery system can be complex with outcomes complicated by social vulnerabilities in the lives of children on OPAT. Our goal was to better understand the psycho-social challenges pediatric families face undergoing OPAT. Methods Caregivers of patients discharged on parenteral or prolonged oral antibiotics and referred to Doernbecher Children’s Hospital OPAT program between July 1, 2017 and December 31, 2017 were eligible for enrollment. We assessed health-related social vulnerabilities using a pre-discharge survey of pediatric caregivers. Child-specific medical information was collected by EMR review. Descriptive statistics were used to characterize social challenges. Results Twenty-six caregivers completed the survey. Mean patient age was 7.7 years. Infections included osteomyelitis (31%), endocarditis or infectious thrombophlebitis (19%), brain abscess or meningitis (15%), complicated pneumonia (12%), device-related infections (12%), or other (12%). Combined, patients spent 1,150 days on OPAT (390 parenteral; 760 prolonged oral antibiotic days). Of the social vulnerabilities endorsed, economic hardship featured prominently with 31% of caregivers having difficulty paying for food, housing or utilities and 12% having problems with appliances working at home. Among the caregivers, 23% reported inadequate social support, 42% reported psychological problems (31% anxiety; 19% depression), 15% reported involvement with child protective services, and 19% reported other legal concerns. 27% had difficulty getting time off work and 31% requested extra help with coordination of healthcare services. 58% of caregivers had a high school degree or less. Conclusion We identified a large number of social vulnerabilities that likely impact pediatric OPAT care after discharge. Identifying social vulnerabilities for pediatric OPAT patients prior to discharge, such as health literacy or barriers to return visits, could better enable treatment customization or prompt care coordination that better supports pediatric OPAT patients.

Abstract
AIMS The purpose of the study was to demonstrate feasibility of the Conserved Domains Database (CDD) for identification of novel biocatalysts with desirable properties from a class of well-characterized biocatalysts. METHODS AND RESULTS The thermostable ADH from Sulfolobus solfataricus with a broad substrate range was applied as a template for the search for novel thermostable ADHs via CDD. From the resulting hits, a putative ADH gene from the thermophilic organism Chloroflexus aurantiacus was cloned and expressed in Escherichia coli. The resulting enzyme was purified and characterized. With a temperature activity optimum of 70°C and a broad substrate spectrum especially for diketones, a versatile new biocatalyst was obtained. CONCLUSIONS Database-based mining in CDD is a suitable approach to obtain novel biocatalysts with desirable properties. Thereby, the available diversity of similar but not equal enzymes within this class can be increased. SIGNIFICANCE AND IMPACT OF THE STUDY For industrial applications, there is a demand for larger diversity of similar well-characterized enzymes in order to test them for a given process (biodiversity screening). For fundamental science, the comparison of enzymes with similar function but different sequence can provide insight into structure function relationships or the evolution of enzymes. This study gives a good example on how this demand can be efficiently met.

Abstract
Sustained inflammation is a crucial pathologic component in atherosclerosis and type 2 diabetes (T2D). A common molecular player driving auto-inflammation in both diseases is the CD40/CD154 inflammatory dyad. By normalizing the aberrant contact dependent interaction of the CD40/CD154 dyad, and resultant auto-inflammation, multiple studies have shown both prevention and therapeutic efficacy in both diseases.
We designed a series of peptides derived from the CD154 protein sequence that are capable of binding directly to the CD40 receptor to interrupt the inflammatory signal pathways. Two peptides, KGYY6 and KGYY15, were highly effective, initially demonstrating efficacy in type one diabetes mouse models. KGYY6 was chosen for additional testing in the T2D model with atherosclerosis.
ApoE-/- mice were utilized due to their ability to develop severe vascular disease and acquire the elements of T2D after 16 weeks of a high fat diet (HFD). KGYY6 was administered by IV tail injection at a dose of 1mg/kg and compared to controls given vehicle only.
Aortic en-Face analysis with Sudan IV stain demonstrated significant reduction in plaque in KGYY6 treated mice. Decreases in plaque area and changes in both smooth muscle and collagen measurement were additionally noted by sequential 5um aortic cross sections from the aortic valve leaflets into the ascending aorta. In-vitro analysis of CD3+CD4+CD40+ splenic cells demonstrated a reduction in inflammatory cytokine expression in response to KGYY6 treatment, specifically IL2, IFNγ, and IL17, which are potent cytokines in atherosclerosis.
Western blot analysis performed on adipose and muscle tissue demonstrated an increased expression of the glucose transport protein GLUT 4, with corresponding glucose tolerance testing demonstrating increased glucose tolerance and improved insulin sensitivity with lowered plasma insulin level.
KGYY6 normalizes the aberrant CD40/CD154 interaction, reducing inflammatory cytokines and regulating glucose, all together resulting in abrogating atherosclerosis.

Abstract
Background This cluster randomised control trial is designed to evaluate whether the Communities That Care intervention (CTC) is effective in reducing the proportion of secondary school age adolescents who use alcohol before the Australian legal purchasing age of 18 years. Secondary outcomes are other substance use and antisocial behaviours. Long term economic benefits of reduced alcohol use by adolescents for the community will also be assessed. Methods Fourteen communities and 14 other non-contiguous communities will be matched on socioeconomic status (SES), location, and size. One of each pair will be randomly allocated to the intervention in three Australian states (Victoria, Queensland and Western Australia). A longitudinal survey will recruit grade 8 and 10 students (M = 15 years old, N = 3500) in 2017 and conduct follow-up surveys in 2019 and 2021 (M = 19 years old). Municipal youth populations will also be monitored for trends in alcohol-harms using hospital and police administrative data. Discussion Community-led interventions that systematically and strategically implement evidence-based programs have been shown to be effective in producing population-level behaviour change, including reduced alcohol and drug use. We expect that the study will be associated with significant effects on alcohol use amongst adolescents because interventions adopted within communities will be based on evidence-based practices and target specific problems identified from surveys conducted within each community. Trial registration The trial was retrospectively registered in September, 2017 (ACTRN12616001276448), as communities were selected prior to trial registration; however, participants were recruited after registration. Findings will be disseminated in peer-review journals and community fora.

Abstract
Zoonotic transmission of Salmonella infections causes an estimated 11% of salmonellosis annually in the United States. This report describes the epidemiologic, traceback and laboratory investigations conducted in the United States as part of four multistate outbreaks of Salmonella infections linked to small turtles. Salmonella isolates indistinguishable from the outbreak strains were isolated from a total of 143 ill people in the United States, pet turtles, and pond water samples collected from turtle farm A, as well as ill people from Chile and Luxembourg. Almost half (45%) of infections occurred in children aged <5 years, underscoring the importance of the Centers for Disease Control and Prevention recommendation to keep pet turtles and other reptiles out of homes and childcare settings with young children. Although only 43% of the ill people who reported turtle exposure provided purchase information, most small turtles were purchased from flea markets or street vendors, which made it difficult to locate the vendor, trace the turtles to a farm of origin, provide education and enforce the United States federal ban on the sale and distribution of small turtles. These outbreaks highlight the importance of improving public awareness and education about the risk of Salmonella from small turtles not only in the United States but also worldwide.
