Abstract
BACKGROUND Up to a quarter of inpatients in high-income countries (HICs) self-report beta-lactam allergy (BLA), which if incorrect,increases the use of alternative antibiotics, worsening individual health outcomes and driving bacterial resistance. In HICs, up to 95% ofself-reported BLAs are incorrect. The epidemiology of BLA in low- and middle-income African countries is unknown. OBJECTIVES To describe the epidemiology and de-labelling outcomes of self-reported BLA in hospitalised South African (SA) patients. METHODS Point-prevalence surveys were conducted at seven hospitals (adult, paediatric, government and privately funded, district andtertiary level) in Cape Town, SA, between April 2019 and June 2021. Ward prescription records and in-person interviews were conductedto identify and risk-stratify BLA patients using the validated PEN-FAST tool. De-labelling was attempted at the tertiary allergy clinic atGroote Schuur Hospital. RESULTS A total of 1 486 hospital inpatients were surveyed (1 166 adults and 320 children). Only 48 patients (3.2%) self-reported a BLA,with a higher rate in private than in government-funded hospitals (6.3% v. 2.8%; p=0.014). Using the PEN-FAST tool, only 10.4% (n=5/48)of self-reported BLA patients were classified as high risk for true penicillin hypersensitivity. Antibiotics were prescribed to 70.8% (n=34/48)of self-reported BLA patients, with 64.7% (n=22/34) receiving a beta-lactam. Despite three attempts to contact patients for de-labelling atthe allergy clinic, only 3/36 underwent in vivo testing, with no positive results, and 1 patient proceeded to a negative oral challenge. CONCLUSION Unlike HICs, self-reported BLA is low among inpatients in SA. The majority of those who self-reported BLA were low risk fortype 1 hypersensitivity, but outpatient de-labelling efforts were largely unsuccessful.

Abstract
In advanced stages of Kienböck's disease, the lunate is no longer conservable. One of the surgical options is to resect the lunate and replace it with a prosthesis. The procedure consisted in lunate resection and interposition of a free APSI® or Pi2® pyrocarbon implant through a dorsal approach. Follow-up was clinical and radiological on QuickDASH and PRWE scores. At a median follow-up of 3 years, 12 patients were reviewed, with a median age of 56 years. Flexion significantly decreased from 42° to 28° (p < 0.01). Extension and pronation-supination were conserved. Strength was 94% compared to the opposite side, with no significant difference from the preoperative measurement. Median QuickDASH and PRWE scores were 15.9 and 23.5 respectively and had significantly improved. One patient underwent scaphocapitate fusion because she was still in pain; the other patients were pain-free. No patients had to change jobs because of their wrist. Radiographically, there was no carpal collapse and carpal height was conserved. Radioscaphoid angle and ulnar translation were stable. There was 1 case of asymptomatic implant dislocation. Interposition of a pyrocarbon implant after lunate resection in advanced Kienböck's disease is a motion-conserving procedure that provides pain relief and functional recovery in the short and medium term. LEVEL OF EVIDENCE: IV.

Abstract
Abstract
Background
Sphingolipids are a class of bioactive signaling molecules implicated in multiple cellular processes and molecular pathways. Many publications have indicated that among these sphingolipids, sphingosine-1-phosphate (S1P) is a key sphingolipid that promotes cancer cell survival and proliferation, activates multiple oncogenic pathways, and stimulates immuno-suppressor cell populations promoting a pro-tumoral microenvironment. Many of these publications have also implicated S1P with chemotherapy induced peripheral neuropathy, a debilitating and serious side effect that may impact therapeutic treatments and patient’s quality of life.
Material and Methods
BXQ-350 is a nanovesicle of Saposin C, an allosteric activator of sphingolipid metabolism, that has broad anticancer activity, potentially in part by lowering systemic S1P levels. BXQ-350 was investigated in a Phase 1 dose-escalation safety study in an all-comer cancer patients with advanced solid malignancies, including CNS tumors (NCT02859857) to determine its safety profile and its potential clinical activity as a single agent in cancer patients. Samples were collected to determine pharmacokinetics and explore potential biomarkers.
Results
11 patients (~15% of evaluable patients) with advanced disease had a clinical benefit and amongst these, 8 patients (~11% of evaluable patients) had PFS> 6 months with 2 patients still on study five years after enrollment. Analysis of patient’s samples revealed that BXQ-350 decreases systemic S1P levels in the majority of the patients experiencing a clinical benefit. In addition, several patients with established CIPN spontaneously reported improvements of their symptoms shortly after BXQ-350 administration. Analysis of these patients’ samples also revealed that S1P systemic levels had decreased, as well as pro-inflammatory cytokines associated with CIPN.
Conclusion
While these results are exploratory and preliminary in nature, they suggest that BXQ-350’s mechanism of action may represent a novel anti-cancer approach that may also mitigate CIPN.

Abstract
Background COVID‐19 has caused a global shift in healthcare‐seeking behaviour; however, presentation rates with serious conditions, such as stroke in low COVID‐19‐prevalence cities, has received less attention. Aims To determine if there was a significant reduction in stroke admissions, delivery of acute reperfusion therapies, or increased delays to presentation during the first wave of the COVID‐19 pandemic. Methods A multicentre, retrospective, observational cohort study was performed across three tertiary hospitals in Brisbane, Australia. Cases were identified using ICD‐10 codes and then individually reviewed for eligibility using prespecified inclusion and exclusion criteria. All metrics were compared over 3 months from 1 March to 31 May 2020 with two corresponding 3‐month periods in 2018 and 2019. Results There was a mean of 2.15 (95% CI 1.87–2.48) stroke admissions per day in the examined pandemic months compared with 2.13 (95% CI 1.85–2.45) and 2.26 (95% CI 1.97–2.59) in March to May 2018 and 2019 respectively, with no significant difference found (P = 0.81). There was also no difference in rates of intravenous thrombolysis (P = 0.82), endovascular thrombectomy (P = 0.93) and time from last known well to presentation (P = 0.54). Conversely, daily emergency department presentations (including non‐stroke presentations) significantly reduced (P < 0.0001). Conclusions During the early months of the COVID‐19 pandemic there was no significant reduction in stroke presentations, use of acute reperfusion therapies or delays to presentation, despite a reduction in ED presentations for any cause. Our results differ from the global experience, with possible explanations, including differences in public health messaging and healthcare infrastructure.

Abstract
Volatile organic compounds (VOC) detected in human breath, urine, stool, sweat, saliva, and blood result from metabolic processes in the body during health or disease. Using sophisticated measurement systems, small amounts of these compounds can be detected in the above bodily fluids. Multiple studies in adults and children have shown the potential of these compounds to differentiate between healthy individuals and patients by detecting profiles of compounds in non-invasively collected samples. However, the detection of biomarkers in VOCs from neonates is particularly attractive due to the non-invasive nature of its approach, and its ability to track disease progress by longitudinal sampling. In this work we have reviewed the literature on the use of VOCs in neonates and identified areas for future work.

Abstract
The recent advances in 3D-printed silicone (PDMS: polydimethylsiloxane) implants present prospects for personalized implants with highly accurate anatomical conformity. However, a potential adverse effect, such as granuloma formation due to immune reactions, still exists. One potential way to overcome this problem is to control the implant/host interface using immunomodulatory coatings. In this study, a new cytokine cocktail composed of interleukin-10 and prostaglandin-E2 was designed to decrease adverse immune reactions and promote tissue integration by fixing macrophages into M2 pro-healing phenotype for an extended period of time. In vitro, the cytokine cocktail maintained low levels of pro-inflammatory cytokine (TNF-α and IL-6) secretions and induced the secretion of IL-10 and the upregulation of multifunctional scavenging and sorting receptor stabilin-1, expressed by M2 macrophages. This cocktail was then loaded in a gelatine-based hydrogel to develop an immunomodulatory material that could be used as a coating for medical devices. The efficacy of this coating was demonstrated in an in vivo rat model during the reconstruction of a tracheal defect by 3D-printed silicone implants. The coating was stable on the silicone implants for over 2 weeks, and the controlled release of the cocktail components was achieved for at least 14 days. In vivo, only 33% of the animals with bare silicone implants survived, whereas 100% of the animals survived with the implant equipped with the immunomodulatory hydrogel. The presence of the hydrogel and the cytokine cocktail diminished the thickness of the inflammatory tissue, the intensity of both acute and chronic inflammation, the overall fibroblastic reaction, the presence of oedema and the formation of fibrinoid (assessed by histology) and led to a 100% survival rate. At the systemic level, the presence of immunomodulatory hydrogels significantly decreased pro-inflammatory cytokines such as TNF-α, IFN-γ, CXCL1 and MCP-1 levels at day 7 and significantly decreased IL-1α, IL-1β, CXCL1 and MCP-1 levels at day 21. The ability of this new immunomodulatory hydrogel to control the level of inflammation once applied to a 3D-printed silicone implant has been demonstrated. Such thin coatings can be applied to any implants or scaffolds used in tissue engineering to diminish the initial immune response, improve the integration and functionality of these materials and decrease potential complications related to their presence.

Abstract
This study investigates the feedbacks between an interactive sea surface temperature (SST) and the self-aggregation of deep convective clouds, using a cloud-resolving model in nonrotating radiative-convective equilibrium. The ocean is modeled as one layer slab with a temporally fixed mean but spatially varying temperature. We find that the interactive SST decelerates the aggregation and that the deceleration is larger with a shallower slab, consistent with earlier studies. The surface temperature anomaly in dry regions is positive at first, thus opposing the diverging shallow circulation known to favor self-aggregation, consistent with the slower aggregation. But surprisingly, the driest columns then have a negative SST anomaly, thus strengthening the diverging shallow circulation and favoring aggregation. This diverging circulation out of dry regions is found to be well correlated with the aggregation speed. It can be linked to a positive surface pressure anomaly (PSFC), itself the consequence of SST anomalies and boundary layer radiative cooling. The latter cools and dries the boundary layer, thus increasing PSFC anomalies through virtual effects and hydrostasy. Sensitivity experiments confirm the key role played by boundary layer radiative cooling in determining PSFC anomalies in dry regions, and thus the shallow diverging circulation and the aggregation speed.

Abstract
Abstract
Introduction
Acute dyspnoea is a major reason for admission to the emergency department and has been associated with high rates of readmission and mortality. However, the association of readmission with mortality risk has not been widely studied in patients with acute dyspnoea.
Purpose
To determine whether unplanned readmission during first 6 months after discharge is associated with greater risk of death within 1 year in patients with acute dyspnoea.
Methods
Derivation cohort consisted of 1371 patients from the prospective observational study, which enrolled acute dyspnoea patients admitted to emergency departments of two university centres from 2015 to 2017 and discharged alive from the hospital. Cox regression analysis compared 1-year risk of death between readmitted vs. non-readmitted patients in the first 6 months after discharge. In addition, we studied this association in 1986 patients from a multicentre validation cohort, which included acute dyspnoea patients from 2006 to 2014. Sensitivity analysis was done in the subgroups divided by cause of index admission (acute heart failure [AHF] and non-AHF) and cause of the first readmission (cardiovascular [CV] or non-CV). The statistical analyses were performed using R statistical software. P value of <0.05 was considered statistically significant.
Results
In the derivation cohort 666 (49%) of patients were readmitted at 6 months and 282 (21%) died in 1 year. Readmitted patients died more frequently than non-readmitted patients (211 [32%] vs. 71 [10%], respectively, p<0.001). All-cause 6-month readmission was associated with an increased 1-year risk of death in a multivariate analysis in both the derivation cohort (adjusted hazard ratio (aHR) 3 [95% confidence interval (CI) 2.2–4], p<0.001) and the validation cohort (aHR 1.8 [95% CI 1.4–2.2], p<0.001). Moreover, deleterious effect of readmission on 1-year survival was equally observed in AHF and non-AHF patients, independent of whether the reason of first readmission was cardiovascular or non-CV, in both study cohorts. The results are displayed in Figure 1.
Figure 1. Main results of the study
Conclusions
Our data demonstrates that readmission is associated with a markedly increased risk of death within 1 year in patients presenting to the emergency department with acute dyspnoea. Furthermore, the detrimental relationship between outcomes is similar in non-cardiac and cardiac causes.

Abstract
Osteoarthritis (OA) is a debilitating disease in dogs. Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used to treat OA; however, many dogs do not obtain adequate pain relief with an NSAID alone. This pilot study evaluated the systemic anti-inflammatory and mobility enhancing effects of an eggshell membrane-based nutritional supplement in dogs with OA-associated pain and mobility impairment. Twenty-seven dogs with OA-associated pain were enrolled into a randomized, double-masked, placebo-controlled, proof of principle pilot study and received either placebo or an eggshell membrane-based nutritional supplement over a 12-week period. Inflammatory biomarkers (IL-2, IL-6, IL-8, tumor necrosis factor-α, C-reactive protein, S100A12, and N-methylhistamine) were measured at Day 0 and Day 84. Owner questionnaires (CBPI and LOAD) were completed at Day 0, Day 42, and Day 84. Differences between groups over time were calculated. Twenty-two dogs completed the pilot study. Inflammatory biomarker IL-2 decreased in the supplement group, compared to the placebo group. Although small, the difference was statistically significant at an alpha of 0.1 (P=0.069). LOAD scores were numerically lower in the supplement group, but not significantly different from the placebo group at Day 0. Day 84 LOAD scores were significantly lower in the supplement group compared to the placebo group (P=0.034). CBPI results did not show the same pattern. The changes in biomarkers and LOAD scores were small, and do not provide definitive evidence of positive effects. However, these pilot results provide a rationale for performing a larger placebo-controlled study of the potential effects of the eggshell membrane-based nutritional supplement.

Abstract
We studied the impact of ionizing radiation at high dose levels (megagray, MGy) on the photometric budget of a radiation-resistant complementary metal oxide semi-conductor (CMOS)-based camera. This is achieved by measuring the radiation-induced degradation of each subpart, namely its illumination system, its optical system, and its CMOS image sensor. The acquired experimental results allow performing a rather realistic simulation of the radiation effects at the system level. Thanks to appropriate mitigation techniques, limited image darkening and color change are obtained at MGy dose levels. The presented results confirm the feasibility of a CMOS-based camera able to resist to MGy dose level of ionizing radiations with an acceptable degradation of the image quality, opening the way to its implementation in the most challenging harsh environments.

Abstract
In veterinary medicine, evaluation of osteoarthritis (OA) treatment efficacy remains challenging. Measurement of activity, utilizing accelerometers, provides a surrogate measure of pain through measuring effects on activity, and the objective data collected can be used to assess the efficacy of treatments. However, little is known about how dog characteristics impact the accelerometry-measured response to treatment. The objectives of this study were to evaluate the effect of signalment and initial impairment level on accelerometer-measured changes in activity in osteoarthritic dogs after receiving a non-steroidal anti-inflammatory (NSAID). Fifty-seven client-owned dogs with OA-associated pain and mobility impairment were administered meloxicam for 2 weeks, following a 2-week baseline, and spontaneous activity was measured using an Actical accelerometer unit. Signalment factors and disease variables were recorded (age, sex, weight, impairment level, forelimb or hindlimb pain). Initial degree of impairment had a significant effect on changes in weekly (P=0.009), weekday (P=0.044) activity following NSAID treatment. Greater initial impairment was associated with larger positive changes in activity. Degree of impairment should be taken into consideration during the development of a clinical trial. Appropriate selection of candidates based on initial degree of impairment may permit a greater treatment effect, therefore increasing the power of the study.

Abstract
Objective The objective of this study was to examine patient-provider relationships among American Indians and Alaska Native (AI/AN) patients by examining associations between patient activation, perceived provider weight bias and working alliance. Patient activation is generally defined as having the knowledge, skills and confidence to manage one's health. Methods Among a sample of 87 AI/AN adults presenting for general medical care at an urban clinic in the north-west region of the USA, ordinary least squares regression analysis was completed to examine associations. Results Better working alliance scores were associated with increased patient activation, while perceived provider weight bias was associated with reduced patient activation. In addition, those with class II obesity had decreased patient activation. Conclusion These findings point to the importance of a positive patient-provider relationship in AI/ANs. Optimal patient engagement and subsequent health outcomes warrant additional consideration of patients' perceptions of provider weight bias within the context of health promotion and interventions.

Abstract
BACKGROUND High concentration mesalazine formulations are more convenient than conventional low concentration formulations for the treatment of ulcerative colitis (UC). AIM To compare the efficacy and safety of 1600 mg and 400 mg tablet mesalazine formulations. METHODS Patients with mild-to-moderate active UC (Mayo Clinic Score >5; N=817) were randomised to 3.2 g of oral mesalazine, administered as two 1600 mg tablets once, or four 400 mg tablets twice daily. We hypothesised that treatment with the 1600 mg tablet was non-inferior (within a 10% margin) to the 400 mg tablet for induction of clinical and endoscopic remission at week 8. Open-label treatment with the 1600 mg tablet continued for 26-30 weeks based on induction response. Predictors of treatment response were also explored. RESULTS At week 8, remission occurred in 22.4% and 24.6% of patients receiving the 1600 mg and 400 mg tablets, respectively (absolute difference -2.2%, 95% CI: -8.1% to 3.8%, non-inferiority P=.005). Endoscopic and histopathologic disease activity, leucocyte concentration and age were significantly associated with clinical remission (P=.022, .042, .014 and .023, respectively). At week 38, 43.9% (296/675) of patients who continued treatment with the 1600 mg formulation were in remission, including 70.3% (142/202) of patients who received a reduced dose of mesalazine (1.6 g/d). The overall incidence of serious adverse events was low. CONCLUSIONS Induction therapy with 3.2 mg mesalazine using two 1600 mg tablets once-daily was statistically and clinically non-inferior to a twice-daily regimen using four 400 mg tablets (NCT01903252).

Abstract
The overall median lifespan of domestic dogs has been estimated to 9-12 years, but little is known about risk factors for mortality in aged and a priori healthy dogs. The objective of this retrospective cohort study was to determine which characteristics are associated with mortality in aged and a priori healthy guide dogs, in a retrospective cohort study of 116 guide dogs followed from a systematic geriatric examination at the age of 8-10 years old. A geriatric grid collected the clinical data and usual biological parameters were measured at the time of examination. Univariate (Kaplan-Meier estimates) and multivariable (Cox proportional hazard model) survival analyses were used to assess the associations with time to all-cause death. The majority of dogs were Golden Retrievers (n=48) and Labrador Retrievers (n=27). Median age at geriatric examination was 8.9 years. A total of 76 dogs died during follow-up, leading to a median survival time from geriatric examination of 4.4 years. After adjustment for demographic and biological variables, an increased alanine amionotransferase level (adjusted Hazard Ratio (adjusted HR), 6.2; 95% confidence interval [95%CI], 2.0-19.0; P<0.01), presenting skin nodules (adjusted HR, 1.9; 95% CI, 1.0-3.4; P=0.04), and not being a Labrador Retriever (adjusted HR, 3.3; 95%CI, 1.4-10; P<0.01) were independently associated with a shorter time to death. This study documents independent associations of alanine aminotransferase level, skin nodules and breed with mortality in aged guide dogs. These results may be useful for preventive medical care when conducting a geriatric examination in working dogs.

Abstract
Background Cryptosporidium spp. is a ubiquitous parasite affecting humans as well as domestic and wild vertebrates, causing diarrhea in both immunocompetent and immunocompromised hosts worldwide. Its transmission occurs primarily by the fecal-oral route. In humans, C. parvum and C. hominis are the most prevalent species, whereas immunocompetent and immunocompromised individuals can also be infected by other zoonotic species. Renal transplant patients are prone to develop cryptosporidiosis, which can induce severe and life-threatening diarrhea. Case presentation We report here a series of nearly concomitant cases of acute symptomatic cryptosporidiosis in three renal transplant patients attending the Strasbourg University Hospital Nephrology Unit. The clinical presentation was persistent diarrhea and acute renal failure. The diagnosis was confirmed by microscopic stool examination using a modified Ziehl-Neelsen staining method and species identification by molecular tools. All patients were treated with nitazoxanide and recovered from diarrhea after 14 days of therapy. Conclusion Genotypic species identification was not consistent with an epidemic context, thus underlining the need for genotyping to monitor at risk patients.

Abstract
Eruptive activity at Turrialba Volcano (Costa Rica) has escalated significantly since 2014, causing airport and school closures in the capital city of San José. Whether or not new magma is involved in the current unrest seems probable but remains a matter of debate as ash deposits are dominated by hydrothermal material. Here we use high-frequency gas monitoring to track the behavior of the volcano between 2014 and 2015 and to decipher magmatic versus hydrothermal contributions to the eruptions. Pulses of deeply derived CO2-rich gas (CO2/Stotal > 4.5) precede explosive activity, providing a clear precursor to eruptive periods that occurs up to 2 weeks before eruptions, which are accompanied by shallowly derived sulfur-rich magmatic gas emissions. Degassing modeling suggests that the deep magmatic reservoir is ~8-10 km deep, whereas the shallow magmatic gas source is at ~3-5 km. Two cycles of degassing and eruption are observed, each attributed to pulses of magma ascending through the deep reservoir to shallow crustal levels. The magmatic degassing signals were overprinted by a fluid contribution from the shallow hydrothermal system, modifying the gas compositions, contributing volatiles to the emissions, and reflecting complex processes of scrubbing, displacement, and volatilization. H2S/SO2 varies over 2 orders of magnitude through the monitoring period and demonstrates that the first eruptive episode involved hydrothermal gases, whereas the second did not. Massive degassing (>3000 T/d SO2 and H2S/SO2 > 1) followed, suggesting boiling off of the hydrothermal system. The gas emissions show a remarkable shift to purely magmatic composition (H2S/SO2 < 0.05) during the second eruptive period, reflecting the depletion of the hydrothermal system or the establishment of high-temperature conduits bypassing remnant hydrothermal reservoirs, and the transition from phreatic to phreatomagmatic eruptive activity.

Abstract
BACKGROUND Formic acid 85% constitutes the active substance of a new wart removal agent marketed in France under the name of Objectif ZeroVerrue(®), a product sold over-the-counter for adults and children aged over four years, and on a doctor's recommendation for children aged under four years. Its mechanism of action may involve cellular destruction through dehydration. PATIENTS AND METHODS Herein we report two cases of cutaneous necrosis following application of formic acid 85%. One case was severe, affecting the extremity of the middle finger and involving the underlying extensor apparatus in a girl aged 3 and a half years. This necrosis required the creation of a pedicled fasciocutaneous flap and temporary arthroereisis. DISCUSSION The precautions for use set out in the information leaflet for this preparation based on formic acid must be strictly adhered to by patients. In particular, only one application should be made per week, taking care to avoid adjacent skin. It is essential to suspend treatment if the skin is still erythematous after the previous application, and the treated area must not be occluded with bandages. Doctors must be aware of the risk of necrosis, since their recommendation is required for children under the age of four years.

Abstract
OBJECTIVES The aim of the study was to assess the incidence of adverse effects (AE) reported with etonogestrel contraceptive implant in France (Implanon® and Nexplanon®). MATERIALS AND METHODS All cases of AE or unintended pregnancies reported to health authorities or to the firm were analyzed. RESULTS During 10 years, 5433 AE and 789 unintended pregnancies were reported. Only 388 (7 %) were serious. There were 1137 reports of difficulties to remove, failure to locate or migration, 430 of insertion difficulties and 203 of deformation or expulsion of the implant. Among other AE, the most common were 1694 gynecological AE, 524 skin reactions and 437 metabolic AE. Since the marketing of Nexplanon® which causes less deep insertions, the incidence of migrations, removal or insertion difficulties has decreased overall (0.92 vs. 1.31/1000 patients), particularly the incidence of removal difficulties, location failures or migrations (0.12 vs 1.01/1000). The infrequent but serious AE were infectious complications at the implant site and pregnancies. When the circumstances of the pregnancy were known, the contraceptive failure was due to the apparent inefficiency of the implant (n=224), to a technique failure (n=203) or to a drug-drug interaction (n=59). CONCLUSION This study confirms that AE of this implant are frequent but not serious, except for the pregnancies. The incidence of complications related to insertion decreased with Nexplanon®. Among other preventable AE, unintended pregnancies due to a drug-drug interaction would require to be better known by the practitioner.

Abstract
Background In veterinary clinical pain studies, there is a paucity of data on test‐retest variability in Clinical Metrology Instruments (CMIs), and it is unknown whether CMIs should be administered using independent (respondents not permitted to see previous answers) or dependent (respondents shown previous answers) interviewing. Objectives To compare baseline variability in CMIs designed to assess pain in dogs with osteoarthritis, and compare CMI scores using independent (InD) and dependent interviewing (DI) for the Canine Brief Pain Inventory (CBPI) and the Client‐Specific Outcome Measures (CSOM). Animals Fifty‐one client‐owned dogs with radiographic evidence of osteoarthritis and associated pain. Methods Clinical Metrology Instruments data were collected during 2 randomized, double‐masked, placebo‐controlled, proof of principle pilot studies with parallel treatment groups. Enrolled dogs received either placebo or antinerve growth factor antibody (NV‐01). Results Agreement between baseline CMI scores was good (CBPI Pain P = .29, CBPI Interference P = .32, CSOM P = .036, LOAD P = .67, HCPI P = .27), being best for the LOAD (ICC = 0.89). CMI responses collected during independent and dependent interviewing were not statistically different (CBPI Pain P = .33, CBPI Interference P = .28, CSOM P = .42) and showed good agreement. Additionally, dependent interviewing resulted in increased treatment effect sizes. Conclusions and Clinical Importance There is little difference between independent and dependent interviewing, however, dependent interviewing resulted in increased treatment effect sizes. By using dependent interviewing, investigators could increase clinical trial power through minimal change to study design. Further research is warranted to investigate the use of dependent interviewing.

Abstract
This study evaluated the effect of different protocols of low-temperature degradation simulation on the mechanical behavior (structural reliability and flexural strength), the surface topography (roughness), and phase transformation of a Y-TZP ceramic. Disc-shaped specimens (1.2mm×12mm, Lava Frame, 3M ESPE, Seefeld, Germany) were manufactured according to ISO:6872-2008 and divided (n=30) according to the aging protocol executed: "Ctrl" - as-sintered - without any treatment; "Dist Water" - stored at distilled water at 37°C for 365 days; "MC" mechanical cycling into two steps: First - 200N, 2.2Hz for 2.000.000 cycles, Second - 450N, 10Hz for 1.000.000 cycles; "Aut" - steam autoclave at 134°C, 2bar (200kPa) for 20h; "Aut+MC"- Aut and MC methods. Roughness analysis (μm) showed, for Ra parameter, higher statistically significant values for Ctrl 0.68 (0.27), while for Rz parameter, the highest values were observed for Ctrl 4.43(1.53) and Aut 2.24 (0.62). Surface topography analysis showed that none aging method promoted surface alterations when compared to control group. Phase transformation analysis showed that all aging methods promoted an increase in m-phase content (Ctrl: 0.94%, Dist Water: 20.73%, MC: 9.47%, Aut: 53.33% and Aut+MC: 61.91%). Weibull Analysis showed higher statistical characteristic strength values for Aut (1033.36MPa) and Dist Water (1053.76MPa). No aging method promoted deleterious impact either on the biaxial flexural strengths or on the structural reliabilities (Weibull moduli). Also, none of the aging methods promoted reduction of Y-TZP mechanical properties; thus the development of new methodologies and the association between mechanical stimuli and hydrothermal degradation should be considered to better understand the mechanism of low-temperature degradation.

Abstract
BACKGROUND Human papillomavirus (HPV) has emerged as a causative agent and positive prognostic factor for oropharyngeal (OP) head and neck squamous cell cancer (HNSCC). This prompts inquiry into whether therapy improvements or increasing incidence of HPV drives the apparent improvements in HNSCC outcomes observed in non-randomized clinical trials. PATIENTS AND METHODS We reviewed all locoregionally advanced HNSCC patients treated with chemotherapy and radiation in prospective institutional trials at a single institution. Patients were divided into three groups (1, 2, 3) according to treatment time period (1993-1998, 1999-2003, 2004-2010, respectively). We reasoned that if a favorable trend was observed over time in OP but not non-OP patients, HPV status may be confounding treatment effects, whereas this would be unlikely if both subgroups improved over time. RESULTS Four hundred and twenty-two patients were identified with OP (55.7%) and non-OP (44.3%) HNSCC. Five-year OP overall survival (OS) improved from 42.3% (group 1) to 72.5% (group 2), and 78.4% (group 3), adjusted P = 0.0084. Non-OP 5-year OS was 51.0% (group 1), 58.8% (group 2), and 66.3% (group 3), adjusted P = 0.51. Five-year recurrence-free survival (RFS) improved for OP groups from 42.3% to 68.4% to 75.8% (adjusted P = 0.017). Non-OP 5-year RFS was 42.9%, 53.6%, and 61.7% for sequential groups (adjusted P = 0.30). Five-year OP distant failure-free survival (DFFS) improved from 42.3% to 71.1% to 77.8% (adjusted P = 0.011). Five-year non-OP DFFS was 46.9%, 57.1%, and 66.0% for sequential groups (adjusted P = 0.38). CONCLUSIONS Over the past two decades, OP HNSCC outcomes improved significantly, while non-OP outcomes only trended toward improvement. Although our patients are not stratified by HPV status, improving OP outcomes are likely at least partly due to the increasing HPV incidence. These data further justify trial stratification by HPV status, investigations of novel approaches for carcinogen-related HNSCC, and current de-intensification for HPV-related HNSCC.

Abstract
The beginning of September 1859 was the occasion of the first and unique observation of a giant solar white light flare, auroral displays were observed at low latitudes and geomagnetic observatories recorded exceptional storms. This paper reviews the impact of the event on the earth system with a special emphasis on living processes using the historical record and current scientific analysis. The data used includes reports from the telegraph operators, mortality and morbidity records, proxies as agricultural production. Comparisons with later solar flare events will be attempted on the basis of the record and the consequences of an event of comparable magnitude to the 1859 set of flares will be discussed.
