Abstract
Prolonged exposure to benzene, a prevalent volatile organic compound (VOC), at concentrations found in smoke, triggers hyperglycemia, and inflammation in mice. Corroborating this with existing epidemiological data, we show a strong correlation between environmental benzene exposure and metabolic impairments in humans. To uncover the underlying mechanisms, we employed a controlled exposure system and continuous glucose monitoring (CGM), revealing rapid blood glucose surges and disturbances in energy homeostasis in mice. These effects were attributed to alterations in the hypothalamic transcriptome, specifically impacting insulin and immune response genes, leading to hypothalamic insulin resistance and neuroinflammation. Moreover, benzene exposure activated microglial transcription characterized by heightened expression of IKKβ/NF-κB-related genes. Remarkably, selective removal of IKKβ in immune cells or adult microglia in mice alleviated benzene-induced hypothalamic gliosis, and protected against hyperglycemia. In summary, our study uncovers a crucial pathophysiological mechanism, establishing a clear link between airborne toxicant exposure and the onset of metabolic diseases.

Abstract
Background Population-based colorectal cancer (CRC) screening programs aim to minimize disparities in CRC rates through universal access. However, Canadian CRC mortality rates remain inversely associated with socioeconomic status and rural residence. In the United States some racialized groups have higher rates of advanced adenomas and CRC. Little is known about pre-cancerous findings or CRC mortality amongst racialized groups in Canada because race and ethnicity data are not routinely collected. Purpose To determine whether FIT-positive colonoscopy incident adenomas and CRC differ on the basis of sex, race, and regional population density in a provincial CRC screening program. Method In this retrospective cohort study drawn from the Nova Scotia Colon Cancer Prevention Program database, we identified adults who had a positive FIT from 2011 to 2021. This report describes incident adenomas and CRC, stratified by sex, race (white vs. racialized groups), and regional population density (urban vs. rural). Racialized groups included those who self-identified as Black/African Canadian, Asian, Middle Eastern and Indigenous. Urban was defined as population centers with more than 5000 individuals. Colonoscopy findings were categorized as no findings, low-risk adenoma (LRA), high-risk adenoma (HRA), or CRC. Comparison between categorical variables was performed with a chi-square test and a t-test for continuous variables. P-value <0.05 was considered significant. Result(s) 41,209 adults (mean age 63.9) had a positive FIT and 34,636 went on to have a colonoscopy offered by the screening program. The FIT-positive colonoscopy participation rate was 84%. Of the 16% overall with a positive FIT but no screening program colonoscopy, 83% had a program consultation but did not proceed with endoscopy for unspecified reasons, 9% declined, and 8.2% are unknown. The overall rate of CRC was 2.4% (n=825) and the adenoma-detection rate was 60.4% (n=20,932). CRC (mean age 65.4) and HRA (mean age 64.6) were associated with older age (p <0.01). Males were more likely to have HRA (38.4% of males) or LRA (26.6% of males) identified compared to females, and females were more likely to have no colonoscopy findings (47.8% of females). CRC was more likely to be identified in urban (2.8%) than rural sub-populations (2.0%). No difference in adenomas or CRC incident rates were noted between white and racialized sub-groups. Image ![]()
Conclusion(s) This analysis of a provincial CRC screening program suggests that males and urban sub-populations had more high-risk findings during FIT-positive colonoscopies. In the first reported Canadian data, incident rates of adenomas and CRC were similar in white and racialized sub-groups.

Abstract
Wind speeds measured by the Mars 2020 Perseverance rover in Jezero crater were fitted as a Weibull distribution. InSight wind data acquired in Elysium Planitia were also used to contextualize observations. Jezero winds were found to be much calmer on average than in previous landing sites, despite the intense aeolian activity observed. However, a great influence of turbulence and wave activity was observed in the wind speed variations, thus driving the probability of reaching the highest wind speeds at Jezero, instead of sustained winds driven by local, regional, or large-scale circulation. The power spectral density of wind speed fluctuations follows a power-law, whose slope deviates depending on the time of day from that predicted considering homogeneous and isotropic turbulence. Daytime wave activity is related to convection cells and smaller eddies in the boundary layer, advected over the crater. The signature of convection cells was also found during dust storm conditions, when prevailing winds were consistent with a tidal drive. Nighttime fluctuations were also intense, suggesting strong mechanical turbulence. Convective vortices were usually involved in rapid wind fluctuations and extreme winds, with variations peaking at 9.2 times the background winds. Transient high wind events by vortex-passages, turbulence, and wave activity could be driving aeolian activity at Jezero. We report the detection of a strong dust cloud of 0.75-1.5 km in length passing over the rover. The observed aeolian activity had major implications for instrumentation, with the wind sensor suffering damage throughout the mission, probably due to flying debris advected by winds.

Abstract
Martian atmospheric dust is a major driver of weather, with feedback between atmospheric dust distribution, circulation changes from radiative heating and cooling driven by this dust, and winds that mobilize surface dust and distribute it in the atmosphere. Wind-driven mobilization of surface dust is a poorly understood process due to significant uncertainty about minimum wind stress and whether the saltation of sand particles is required. This study utilizes video of six Ingenuity helicopter flights to measure dust lifting during helicopter ascents, traverses, and descents. Dust mobilization persisted on takeoff until the helicopter exceeded 3 m altitude, with dust advecting at 4-6 m/s. During landing, dust mobilization initiated at 2.3-3.6 m altitude. Extensive dust mobilization occurred during traverses at 5.1-5.7 m altitude. Dust mobilization threshold friction velocity of rotor-induced winds during landing is modeled at 0.4-0.6 m/s (factor of two uncertainty in this estimate), with higher winds required when the helicopter was over undisturbed terrain. Modeling dust mobilization from >5 m cruising altitude indicates mobilization by 0.3 m/s winds, suggesting nonsaltation mechanisms such as mobilization and destruction of dust aggregates. No dependence on background winds was seen for the initiation of dust lifting but one case of takeoff in 7 m/s winds created a track of darkened terrain downwind of the helicopter, which may have been a saltation cluster. When the helicopter was cruising at 5-6 m altitude, recirculation was seen in the dust clouds.

Abstract
BACKGROUND The invasion of Ukraine by Russia in February 2022 has resulted in destruction of healthcare infrastructure and triggered the largest wave of internally displaced populations and refugees since World War Two. Conflicts in transitioned countries such as Ukraine create new non-communicable disease (NCD) challenges, especially for cancer care for refugees and humanitarian assistance in host countries. In the early days, rapid attempts were made to model possible impacts. METHODS By evaluating open source intelligence used in the first three months of the conflict through snowball search methods, we aimed to address: (i) burden of cancer in Ukrainian population, specifically considering translating to the refugees population, and its cancer care capacity; ii) baseline capacity/strengths of cancer systems in initial host countries. Moreover, using a baseline scenario based on crude cancer incidence in Ukraine, and considering data from UNHCR, we estimated how cancer cases would be distributed across host countries. Finally, a surveillance assessment instrument was created, intersecting health system's capacity and influx of internally displaced populations and refugees. FINDINGS AND CONCLUSIONS The total new cancer patients per month in pre-conflict Ukraine was estimated as 13,106, of which < 1 % are paediatric cases. The estimated cancer cases in the refugee population (combining prevalent and incident), assuming 7.5 million refugees by July 2022 and a female:male ratio of 9:1, was 33,121 individuals (Poland: 19284; Hungary: 3484; Moldova: 2651; Slovakia: 2421; Romania: 5281). According to our assessments, Poland is the only neighbouring country classified as green/yellow for cancer capacity, i.e. sufficient ablility to absorb additional burden into national health system; Slovakia we graded as yellow, Hungary and Romania as yellow/red and Moldova as red.

Abstract
Abstract
Background
Frailty is highly prevalent in older hip fracture patients, conferring greater risk of poorer outcomes including increased Length of Stay (LOS), Nursing Home (NH) placement and mortality
Methods
This prospective observational study took place in a large university hospital with a daily trauma list and an established orthogeriatric service. We compared 3 different screening tools; Rockwood Clinical Frailty Scale (CFS), Zuckerman’s Functional Recovery Score (FRS) and New Mobility Score (NMS) and their ability to predict outcomes in hip fracture patients. Participants included all hip fracture patients (>/= 60 years old) admitted to the orthopaedic ward from 2016-2018. Scores were assigned by an ortho-geriatrician and were analysed at admission and at 1 year.
Results
Increasing frailty scores were associated with increased mortality, LOS and NH admission rates. Those with a CFS of 4-6 had an increased risk of mortality compared to those with a CFS of 1-3 (OR:3.81, CI 2.15-6.76). Those with a CFS of 7-9 demonstrated increased risk of mortality compared to those without frailty (OR: 8.75, CI 4.58-16.72). Patients with mild-moderate frailty (CFS 4-6) were 5 times more likely to require NH at 1-year (OR 5.09, CI 3.03-8.56) and those with severe frailty (CFS 7-9) were 7 times more likely to be in a NH at 1-year (OR 7.03, CI 3.82-12.94). The moderate frailty group had an inpatient stay 16 days longer than the non-frail group and the severe frailty group, 26 days longer than the non-frail group. Results were similar for FRS and NMS and when adjusted for age. Comparing the discrimination of the different measures for predicting survival, analysis of receiver operating characteristic curves revealed - 0.73 (CFS), 0.72 (NMS) 0.74 (FRS). Interestingly, the mortality rate for men was 32% compared to 21% for females (OR: 1.75 p=0.005).
Conclusion
Assessing frailty with a standardised protocol could reliably estimate the risk of adverse outcomes in hip fracture patients.

Abstract
Abstract
Background
The use of immune checkpoint inhibitors (ICI) has been associated with a 3-fold higher risk for cardiovascular events as compared to cancer patients who did not receive ICI. Therapies targeting vascular endothelial growth factor (VEGF) have also been associated with a wide range of cardiovascular events. The combination use of ICIs and VEGF inhibitors is currently approved as a treatment for patients with renal-cell carcinoma, hepatocellular carcinoma, non-small cell lung cancer, and endometrial cancer. Data are lacking whether the combination of ICIs and VEGF-targeted therapy is associated with an additional increase in cardiovascular events.
Purpose
To evaluate whether the combination use of ICI and VEGF targeted therapies are associated with a higher risk of cardiovascular events as compared to ICI therapy alone, we performed a retrospective matched case-control study.
Methods
Cases received both ICI and VEGF-targeted therapy (n=157), and control patients (n=157) only received ICI therapy. The primary outcome was a composite of cardiovascular events (myocardial infarction, coronary revascularization, ischemic stroke, deep venous thrombosis, and pulmonary embolism). Patients were censored at time of first event or at last date of follow up. Cox proportional hazard regression analysis was performed to calculate hazard ratio (HR) with 95% confidence interval (CI), counting only the first cardiovascular event.
Results
Baseline characteristics for the cases and controls are shown in Table 1. Overall cases (combination ICI and VEGF inhibitor) and controls (ICI alone) were not different with respect to age, type of cancer, and a prior history of any cardiovascular event. Cases received more ICI cycles as compared to controls (median of 7 [4–17] cycles vs. 4 [2–10] cycles, P<0.001). Cases also had a longer follow-up time (334 [127–663] days vs. 201 [60–564] days, P=0.008) as compared to the control group. As compared to ICI alone, a similar risk for a composite cardiovascular event was observed in those who received both ICI and VEGF-targeted therapy (HR, 0.70 [95% CI, 0.39–1.25]; P=0.23, Table 1). In total, 21/157 patients had a composite cardiovascular event among the cases, who received the combination of ICI and VEGF inhibitor (9 DVT, one MI, 9 PE, two ischemic strokes) as compared to 25/157 among the controls, who received ICI alone (14 DVT, 3 MI, 7 PE, one ischemic stroke). The median time to event was not different between the two groups (126 [98–260] days vs. 145 [28–205] days, P=0.47).
Conclusion
We found that among 157 patients who received a combination of ICI and VEGF-targeted therapy and 157 matched control patients who only received ICI therapy, the risk for cardiovascular events was not different between the two groups.

Abstract
Rovers and landers on Mars have experienced local, regional, and planetary-scale dust storms. However, in situ documentation of active lifting within storms has remained elusive. Over 5-11 January 2022 (LS 153°-156°), a dust storm passed over the Perseverance rover site. Peak visible optical depth was ∼2, and visibility across the crater was briefly reduced. Pressure amplitudes and temperatures responded to the storm. Winds up to 20 m s-1 rotated around the site before the wind sensor was damaged. The rover imaged 21 dust-lifting events-gusts and dust devils-in one 25-min period, and at least three events mobilized sediment near the rover. Rover tracks and drill cuttings were extensively modified, and debris was moved onto the rover deck. Migration of small ripples was seen, but there was no large-scale change in undisturbed areas. This work presents an overview of observations and initial results from the study of the storm.

Abstract
The Perseverance rover landed in Jezero crater, Mars, to investigate ancient lake and river deposits. We report observations of the crater floor, below the crater's sedimentary delta, finding the floor consists of igneous rocks altered by water. The lowest exposed unit, informally named Séítah, is a coarsely crystalline olivine-rich rock, which accumulated at the base of a magma body. Fe-Mg carbonates along grain boundaries indicate reactions with CO2-rich water, under water-poor conditions. Overlying Séítah is a unit informally named Máaz, which we interpret as lava flows or the chemical complement to Séítah in a layered igneous body. Voids in these rocks contain sulfates and perchlorates, likely introduced by later near-surface brine evaporation. Core samples of these rocks were stored aboard Perseverance for potential return to Earth.

Abstract
Abstract
Background
Population-based colorectal cancer (CRC) screening programs aim to minimize inequities in participation through universal access, however, there remain disparities associated with low education, socio-economic status, and population centre. In the United States racialized groups have lower screening participation, and Black and Indigenous adults have higher CRC mortality. There is no Canadian data on racialized group participation in CRC screening because racial and ethnic data is not routinely collected. The Nova Scotia Colon Cancer Prevention Program (NSCCPP) mails fecal immunochemical tests (FIT) biennially to all residents aged 50–74 and allows for optional self-identified race and ethnicity.
Aims
To determine whether participation rates in the NSCCPP differ on the basis of race/ethnicity, age, sex, or population centre. In this preliminary analysis we report screening participation on the basis of race/ethnicity.
Methods
A retrospective cohort study was performed using the NSCCPP database to identify screen-eligible adults who returned a FIT to the program (i.e. participated) from 2011 to 2021. Racialized groups were identified based on self-identification form results allowing for multiple category selections. Race/Ethnicity was categorized as White, Black/African Canadian, Indigenous, Asian, Middle Eastern. The 2016 Canadian census was used to estimate the screen-eligible population (age 50–74) and race/ethnicity group population sizes. Unique participants were identified as individuals who returned one or more FITs in the study period. Unique participants were compared to the screen-eligible population to estimate participation over the 10-year study period.
Results
508,533 FITs were returned over 10 years by 208,702 unique participants. The number of annual FITs returned ranged from 14,066 in 2011 to 65,746 in 2019. Participants were 56% female, 44% male, with a mean age 62.8 (± 7.0). FIT status was 89% negative, 7% positive, and 4% indeterminate. 96% (n=490,398) of participants provided self-identification data. Table 1 provides the screen-eligible population, unique participants, and FIT participation over the 10-year study period all characterized by race/ethnicity. Over 10 years, 59% of the eligible population participated in CRC screening by returning at least one FIT.
Conclusions
CRC screening participation by race/ethnicity in Canada is unknown. This analysis of the NSCCPP suggests that participation by racialized individuals including Black/African Canadian, Asian, and Indigenous, are lower relative to White individuals. Further analyses will explore race/ethnicity and gender in terms of temporal and geographic trends.

Abstract
Abstract
Background
Approximately 25% of inpatients have urinary catheters at some point during their hospital stay; over half are deemed inappropriate. This is significant as catheter-associated urinary tract infections (CAUTI) increase morbidity, mortality and length of hospitalisation. Lack of medical documentation and clinician awareness of catheters have been identified as risk factors for inappropriate catheterisation. The aim of this audit was to assess inpatient urinary catheter use among medical inpatients to determine if the indication and insertion procedure were clearly documented.
Methods
The audit was conducted over one day and included all medical inpatients aged 18 years and above. Emergency Department and High Dependency patients were excluded. Data was collected using standardised data collection sheets and involved a review of medical/nursing notes. Data was benchmarked against Health Service Executive guidelines.
Results
27 of 132 medical inpatients (20%) had a urinary catheter in situ on the day of audit. 37% (n = 10) had long-term urinary catheters in situ prior to admission and are not considered further. Of the remaining 63% (n = 17), 9 were female (53%), 8 were male (47%), and the average age was 75 years. Indication was documented in nursing notes for 76% and in medical notes for 53%. Indications included monitoring urinary output (29%), urinary retention (24%), sepsis (18%), comfort (6%) and haematuria (6%). Catheter insertion procedure was documented in nursing notes for 59% and in medical notes for 12%.
Conclusion
One fifth of medical inpatients had urinary catheters on the day of audit. 63% of these patients did not have a catheter prior to admission. Overall medical documentation of catheter indication and insertion procedure is poor. Better documentation would likely improve clinician awareness of their patient’s catheters and prompt earlier review of appropriateness. Education sessions, insertion proforma stickers and catheter review reminder systems are suggested to improve documentation.

Abstract
Abstract
Background
Neck of femur (NOF) fractures cause significant morbidity and mortality. Many require off site rehabilitation and it can lead to a new functional baseline with increased care needs. The objective of this study was to explore this impact on patients with NOF fractures in a university teaching hospital.
Methods
This retrospective observational study was performed on admitted patients with NOF fractures in 2019. Using a structured proforma, data was collected from the patients’ electronic record and from follow up telephone consultations at one year. Frailty and functional capacity was assessed at one year using the Clinical Frailty Scale and the Barthel Index.
Results
123 patients had a NOF fracture from January to December 2019. The female to men ratio was 2:1 and the average age was 79 years. The majority of patients were admitted from home (86%). At baseline, 58% mobilised independently without aids. On discharge, 39% were transferred to offsite rehab, 41% discharged home and 13% were discharged to a nursing home.
At one year, the mortality rate was 26% which is comparable with other studies [1]. 30% had a new home care package and 19.4% were in a nursing home. 75% were readmitted with a third due to falls. On average, patients were classified as mild to moderately frail (CFS of 4.84) with moderate dependency (Barthel Index of 76.5).
Conclusion
Hip fractures have a high mortality rate and have a significant impact on patient’s function with a third requiring extra support at home and a fifth requiring a nursing home admission. Frailty tools may be useful to help predict outcomes in the future.

Abstract
AIMS Most randomised controlled trials (RCTs) in oncology are now funded by the pharmaceutical industry. We explore the extent to which RCT design, results and interpretation differ between industry-funded and non-industry-funded RCTs. MATERIALS AND METHODS In this cross-sectional analysis, a structured literature search was used to identify all oncology RCTs published globally during 2014-2017. Industry funding was identified based on explicit statements in the publication. Descriptive statistics were used to compare elements of trial methodology and output between industry- and non-industry-funded RCTs. RESULTS The study sample included 694 RCTs; 71% were funded by industry. Industry-funded trials were more likely to test systemic therapy (97% versus 62%; P < 0.001), palliative-intent therapy (71% versus 41%; P < 0.001) and study breast cancer (20% versus 12%; P < 0.001). Industry-funded trials were larger (median sample size 474 versus 375; P < 0.001) and more likely to meet their primary end point (49% versus 41%; P < 0.001). Among positive trials, there were no differences in the magnitude of benefit between industry- and non-industry-funded RCTs. Trials funded by industry were published in journals that had a significantly higher median impact factor (21, interquartile range 7, 28) than non-industry-funded trials (impact factor 12, interquartile range 5, 24; P = 0.005); this persisted when adjusted for whether a trial was positive or negative. CONCLUSIONS The vast majority of oncology RCTs are now funded by industry. Industry-funded trials are larger, more likely to be positive, predominantly test systemic therapies in the palliative setting and are published in higher impact journals than trials without industry support.

Abstract
UNLABELLED The NASA Perseverance rover Mast Camera Zoom (Mastcam-Z) system is a pair of zoomable, focusable, multi-spectral, and color charge-coupled device (CCD) cameras mounted on top of a 1.7 m Remote Sensing Mast, along with associated electronics and two calibration targets. The cameras contain identical optical assemblies that can range in focal length from 26 mm ( 25.5 ∘ × 19.1 ∘ FOV ) to 110 mm ( 6.2 ∘ × 4.2 ∘ FOV ) and will acquire data at pixel scales of 148-540 μm at a range of 2 m and 7.4-27 cm at 1 km. The cameras are mounted on the rover's mast with a stereo baseline of 24.3 ± 0.1 cm and a toe-in angle of 1.17 ± 0.03 ∘ (per camera). Each camera uses a Kodak KAI-2020 CCD with 1600 × 1200 active pixels and an 8 position filter wheel that contains an IR-cutoff filter for color imaging through the detectors' Bayer-pattern filters, a neutral density (ND) solar filter for imaging the sun, and 6 narrow-band geology filters (16 total filters). An associated Digital Electronics Assembly provides command data interfaces to the rover, 11-to-8 bit companding, and JPEG compression capabilities. Herein, we describe pre-flight calibration of the Mastcam-Z instrument and characterize its radiometric and geometric behavior. Between April 26 t h and May 9 t h , 2019, ∼45,000 images were acquired during stand-alone calibration at Malin Space Science Systems (MSSS) in San Diego, CA. Additional data were acquired during Assembly Test and Launch Operations (ATLO) at the Jet Propulsion Laboratory and Kennedy Space Center. Results of the radiometric calibration validate a 5% absolute radiometric accuracy when using camera state parameters investigated during testing. When observing using camera state parameters not interrogated during calibration (e.g., non-canonical zoom positions), we conservatively estimate the absolute uncertainty to be < 10 % . Image quality, measured via the amplitude of the Modulation Transfer Function (MTF) at Nyquist sampling (0.35 line pairs per pixel), shows MTF Nyquist = 0.26 - 0.50 across all zoom, focus, and filter positions, exceeding the > 0.2 design requirement. We discuss lessons learned from calibration and suggest tactical strategies that will optimize the quality of science data acquired during operation at Mars. While most results matched expectations, some surprises were discovered, such as a strong wavelength and temperature dependence on the radiometric coefficients and a scene-dependent dynamic component to the zero-exposure bias frames. Calibration results and derived accuracies were validated using a Geoboard target consisting of well-characterized geologic samples.

Abstract
UNLABELLED Nine simulations are used to predict the meteorology and aeolian activity of the Mars 2020 landing site region. Predicted seasonal variations of pressure and surface and atmospheric temperature generally agree. Minimum and maximum pressure is predicted at Ls ∼ 145 ∘ and 250 ∘ , respectively. Maximum and minimum surface and atmospheric temperature are predicted at Ls ∼ 180 ∘ and 270 ∘ , respectively; i.e., are warmest at northern fall equinox not summer solstice. Daily pressure cycles vary more between simulations, possibly due to differences in atmospheric dust distributions. Jezero crater sits inside and close to the NW rim of the huge Isidis basin, whose daytime upslope (∼east-southeasterly) and nighttime downslope (∼northwesterly) winds are predicted to dominate except around summer solstice, when the global circulation produces more southerly wind directions. Wind predictions vary hugely, with annual maximum speeds varying from 11 to 19 ms - 1 and daily mean wind speeds peaking in the first half of summer for most simulations but in the second half of the year for two. Most simulations predict net annual sand transport toward the WNW, which is generally consistent with aeolian observations, and peak sand fluxes in the first half of summer, with the weakest fluxes around winter solstice due to opposition between the global circulation and daytime upslope winds. However, one simulation predicts transport toward the NW, while another predicts fluxes peaking later and transport toward the WSW. Vortex activity is predicted to peak in summer and dip around winter solstice, and to be greater than at InSight and much greater than in Gale crater.

Abstract
Mastcam-Z is a multispectral, stereoscopic imaging investigation on the Mars 2020 mission's Perseverance rover. Mastcam-Z consists of a pair of focusable, 4:1 zoomable cameras that provide broadband red/green/blue and narrowband 400-1000 nm color imaging with fields of view from 25.6° × 19.2° (26 mm focal length at 283 μrad/pixel) to 6.2° × 4.6° (110 mm focal length at 67.4 μrad/pixel). The cameras can resolve (≥ 5 pixels) ∼0.7 mm features at 2 m and ∼3.3 cm features at 100 m distance. Mastcam-Z shares significant heritage with the Mastcam instruments on the Mars Science Laboratory Curiosity rover. Each Mastcam-Z camera consists of zoom, focus, and filter wheel mechanisms and a 1648 × 1214 pixel charge-coupled device detector and electronics. The two Mastcam-Z cameras are mounted with a 24.4 cm stereo baseline and 2.3° total toe-in on a camera plate ∼2 m above the surface on the rover's Remote Sensing Mast, which provides azimuth and elevation actuation. A separate digital electronics assembly inside the rover provides power, data processing and storage, and the interface to the rover computer. Primary and secondary Mastcam-Z calibration targets mounted on the rover top deck enable tactical reflectance calibration. Mastcam-Z multispectral, stereo, and panoramic images will be used to provide detailed morphology, topography, and geologic context along the rover's traverse; constrain mineralogic, photometric, and physical properties of surface materials; monitor and characterize atmospheric and astronomical phenomena; and document the rover's sample extraction and caching locations. Mastcam-Z images will also provide key engineering information to support sample selection and other rover driving and tool/instrument operations decisions.

Abstract
There are a variety of structural and systems frameworks for describing the building blocks of country’s public health and health systems. In this paper, we propose a conceptual framework for a holistic view of a country’s health service providers in order to inform the plan for Defence Health Engagement activities with partner countries. This includes all potential government ministries involved in healthcare provision, the independent, private sector and the non-government organisation/charity sector. The framework provides a visualisation to support the analysis of a country’s health services providers. We propose that recognising and analysing the different contributions of all these national health providers is essential for understanding the wider political economy of a nation’s health systems. This can inform a plan of Defence Health Engagement for capacity building in crisis response, development and health systems strengthening.

Abstract
BACKGROUND Bone sarcomas are a significant cause of pain, disability, and mortality in dogs. A variety of surgical limb salvage options are available to preserve limb function with comparable prognosis to amputation. CASE REPORT This report describes successful healing after plate fixation of an undifferentiated sarcoma pathologic femoral fracture in a dog. The fracture was treated surgically with curettage of the tumour site, placement of autogenous bone graft, and then stabilized using a locking plate rod construct. The patient regained excellent mobility after surgery and was managed with monthly pamidronate therapy. Serial radiographs demonstrate progressive healing of the pathologic fracture. Ultimately, the patient developed a maxillary fibrosarcoma and was euthanased 1 year after treatment of the femoral fracture. Postmortem histopathological evaluation of the pathologic fracture site demonstrated complete bone healing. CONCLUSION This case highlights the possibilities of limb salvage by fracture stabilization and bone healing as a viable option in select patients.

Abstract
Background: Evidence to guide cancer policy-making is scarce in low- and middle-income countries (LMIC). Furthermore, most economic studies in cancer have been conducted from the provider's or payer's perspective. Aim: The ASEAN Costs in Oncology Study (ACTION) was conducted to provide the essential intelligence for national policymakers and official development assistance donors to construct economically sound national cancer control plans. Methods: In the ACTION study, 9513 newly diagnosed cancer patients from eight LMIC in southeast Asia were prospectively followed-up for adverse economic outcomes up to one year after diagnosis, through serial interviews and use of cost diaries. Results: Country-specific analysis of the ACTION Study data had revealed that just within a year of diagnosis, 1 in 2 Malaysian cancer survivors had reported spending more than 30% of their annual household income for cancer related expenditures (FC: financial catastrophe). Strikingly, Malaysia, albeit being a higher income nation, appeared to have fared worse than Thailand, where only 1 in 3 cancer survivors reported FC. Nonetheless, in contrast to finding of the regional study that medical payments (drugs, hospitalization, consultation), largely explained the incidence of FC following cancer, only half of the reported catastrophic expenditures in Malaysia were attributed to medical expenditures suggesting that nonmedical payments related to cancer (e.g., travel, accommodation, childcare) was an important contributor to adverse financial outcomes. Furthermore, marked institutional variations in levels of catastrophic expenditures were observed in Malaysia, even within the public healthcare system. Proportion of patients experiencing FC in the general government hospitals was only 33% compared with 65% in the public academic hospitals. Although late stage at cancer diagnosis largely explained the increased risk of adverse economic outcomes and death, patients from low-income households remained vulnerable even when diagnosed with earlier stages. Conclusion: The findings of the ACTION Study importantly highlight the need for LMIC to undertake their own studies examining the financial impact of cancer in the population, to take affirmative actions to reduce financial loss and premature deaths associated with cancer. From the Malaysian perspective, there appears to be an urgent need to improve social support for cancer in the country, be it through government-led programs such as disability insurance and short term credit or multisectoral collaboration with civil societies, private industries, and philanthropic organizations. Key policy changes should also include prioritization of programs which would allow early detection of cancer, re-examination of the national health financing system to ensure that public funds are channeled to those who need them the most, and addressing disparities in funding between public hospitals.

Abstract
Background: The National Cancer Institute (NCI) recognizes 'cancer health disparities' as adverse differences in cancer incidence, mortality, and burden that exist among specific population groups. Refugee populations often lack access to primary care and health screening or preventive services, leading to late diagnosis, and higher cancer burdens of cancer-related outcomes and mortality. The disproportionate burden of cancer in refugee populations, necessitates research on specific determinants and disparities influencing their cancer care. Ongoing conflicts across the Middle East and North Africa (MENA) region have caused an unprecedented displacement of individuals to host countries. Four countries in the region, Jordan, Lebanon, Palestinian territories, and Turkey, host more than an estimated 3 million refugees collectively. As the region experiences a shift in disease burden to noncommunicable diseases, the health systems of these host countries are placed under increased pressure to manage chronic conditions of refugees, such as cancer. These large-scale displacements in the MENA region present a unique opportunity to better understand the drivers of health disparities with the aim of improving cancer health in refugee populations. Aim: Through application of a Social Determinants of Health (SDOH) framework, this study aims to understand the landscape of health seeking behaviors for cancer prevention among refugees in Jordan, Lebanon, Palestinian territories, and Turkey. This is a first step to inform future research and initiatives around refugee cancer services. Methods: A systematic literature review was completed according to PRISMA standards, with assistance from the NIH Library. A review protocol was developed, and all literature that met eligibility criteria was included. Thematic coding and analysis was then performed to describe observational associations between cancer prevention behaviors and SDOH among refugees. Results: The results reveal patterns in which SDOH directly and indirectly influence the landscape of refugee health seeking behaviors for cancer prevention services in their host countries. The SDOH that most clearly influenced cancer prevention behaviors include health system capacity, navigating host country's health system, delivery of cancer prevention services, acculturation, competing social, health, and financial priorities, and the built environment. These interrelated constructs impact refugees' ability to access and participate in cancer prevention services, as both enabling and inhibit factors. Conclusion: The influence of SDOH on seeking cancer care are important for refugee populations around the world since they are faced with comparable contextual factors that both enable and inhibit health seeking behaviors. Understanding the interplay between the SDOH constructs is pivotal toward developing targeted interventions by host countries to improve cancer prevention behaviors and health outcomes among refugees.

Abstract
Background In 2000, a Canadian task force recommended that medical oncologists (mos) meet a target of 160-175 new patient consultations per year. Here, we report the Canadian results of a global survey of mo workload compared with mo workload in other high-income countries (hics). Methods Using a snowball method, an online survey was distributed by national oncology societies to chemotherapy-prescribing physicians in 22 hics (World Bank criteria). The survey was distributed within Canada to all members of the Canadian Association of Medical Oncologists. Workload was measured as the annual number of new cancer patient consults per oncologist. Results The survey was completed by 782 oncologists from hics, including 58 from Canada. Median annual consults per mo were 175 in Canada compared with 125 in other hics. The proportions of mos having 100 or fewer consults or more than 300 consults per year were 3% (2/58) and 5% (3/58) in Canada compared with 31% (222/724) and 16% (116/724) in other hics (p < 0.001 and p = 0.023 respectively). The median number of patients seen in a full-day clinic was 15 in Canada and 25 in other hics (p = 0.220). Canadian mos reported spending a median of 55 minutes per new consultation; new consultations of 35 minutes were reported in other hics (p < 0.001). Median hours worked per week was 55 in Canada and 45 in other hics (p = 0.200). Conclusions Although the median annual clinical volume for Canadian mos aligns with recommended targets, half the respondents exceeded that level of activity. Health policymakers and educators have to consider mo workforce supply and alternative models of care in preparation for the anticipated surge in cancer incidence in the coming decade.

Abstract
Abstract
Background
The aim of this RCT was to determine whether elective resection following successful non-operative management of a first episode of acute sigmoid diverticulitis complicated by extraluminal air with or without abscess is superior to observation in terms of recurrence rates.
Methods
This was a single-centre, sequential design RCT. Patients were randomized to elective surgery or observation following non-operative management and colonoscopy. Non-operative management included nil by mouth, intravenous fluids, intravenous antibiotics, CT with intravenous contrast on arrival at hospital, and repeat CT with intravenous and rectal contrast on day 3 in hospital. The primary endpoint was recurrent diverticulitis at 24 months. Patients with a history of sigmoid diverticulitis, immunosuppression or peritonitis were not included.
Results
Of 137 screened patients, 107 were assigned randomly to elective surgery (26) or observation (81), and underwent the allocated intervention after successful non-operative management. Conservative management failed in 15 patients. Groups were similar in age, sex, BMI, co-morbidities and colorectal POSSUM. Rates of recurrent diverticulitis differed significantly in the elective surgery and observation groups (8 versus 32 per cent; P = 0·019) at a mean(s.d.) follow-up of 37·8(8·6) and 35·2(9·2) months respectively. There was also a significant difference in time to recurrence (median 11 versus 7 months; P = 0·015). A total of 28 patients presented with recurrent diverticulitis complicated by extraluminal air and/or abscess (2 elective surgery, 26 observation), all of whom recovered with repeat non-operative management.
Conclusion
The majority of patients observed following conservative management of diverticulitis with local extraluminal air do not require elective surgery. Registration number: NCT01986686 (http://www.clinicaltrials.gov).

Abstract
That a well-developed and hierarchical medical profession existed in Pharaonic Egypt is without doubt. What is a matter of contention is the existence of a recognizable surgical profession, or even of the practice of surgery by medically qualified personnel. Palaeoarchaeological specimens that demonstrate some form of surgical procedure are rare. Medical papyri and the treatises of the historians of antiquity provide a far more reliable source of information on surgical practice. They have indicated possible titles for surgeons, and the types of instruments used.

Abstract
Purpose Open Source Intelligence (OSINT) and Signals Intelligence (SIGINT) from the clandestine intelligence sector are being increasingly employed in infectious disease outbreaks. The purpose of this article is to explore how such tools might be employed in the detection, reporting, and control of outbreaks designated as a 'threat' by the global community. It is also intended to analyse previous use of such tools during the Ebola and SARS epidemics and to discuss key questions regarding the ethics and legality of initiatives that further blur the military and humanitarian spaces. Methods We undertake qualitative analysis of current discussions on OSINT and SIGINT and their intersection with global health. We also review current literature and describe the debates. We built on quantitative and qualitative research done into current health collection capabilities. Results This article presents an argument for the use of OSINT in the detection of infectious disease outbreaks and how this might occur. Conclusion We conclude that there is a place for OSINT and SIGINT in the detection and reporting of outbreaks. However, such tools are not sufficient on their own and must be corroborated for the intelligence to be relevant and actionable. Finally, we conclude that further discussion on key ethical issues needs to take place before such research can continue. In particular, this involves questions of jurisdiction, data ownership, and ethical considerations.

Abstract
The Old World non-human primates (NHP) - baboons (Papio spp.) share similarities with humans regarding fetal and placental development and some pregnancy-related complications. Information about the mechanism of birth and complications arising during parturition in these species is relatively sparse. In this manuscript, we add information from a series of pathological and observational cases to highlight insights and selected complications of birth in Papio spp, based on video-recording of the delivery process, X-ray, MRI, and ultrasound evaluations in pregnant baboons. Additionally, we abstracted pathology records obtained from perinatal loss in a large baboon colony during a 17 year period. The presented cases provide important information for the management of pregnancy and delivery in Papio spp.

Abstract
New neurons are continually generated from the resident populations of precursor cells in selective niches of the adult mammalian brain such as the hippocampal dentate gyrus and the olfactory bulb. However, whether such cells are present in the adult amygdala, and their neurogenic capacity, is not known. Using the neurosphere assay, we demonstrate that a small number of precursor cells, the majority of which express Achaete-scute complex homolog 1 (Ascl1), are present in the basolateral amygdala (BLA) of the adult mouse. Using neuron-specific Thy1-YFP transgenic mice, we show that YFP+ cells in BLA-derived neurospheres have a neuronal morphology, co-express the neuronal marker βIII-tubulin, and generate action potentials, confirming their neuronal phenotype. In vivo, we demonstrate the presence of newly generated BrdU-labeled cells in the adult BLA, and show that a proportion of these cells co-express the immature neuronal marker doublecortin (DCX). Furthermore, we reveal that a significant proportion of GFP+ neurons (~23%) in the BLA are newly generated (BrdU+) in DCX-GFP mice, and using whole-cell recordings in acute slices we demonstrate that the GFP+ cells display electrophysiological properties that are characteristic of interneurons. Using retrovirus-GFP labeling as well as the Ascl1CreERT2 mouse line, we further confirm that the precursor cells within the BLA give rise to mature and functional interneurons that persist in the BLA for at least 8 weeks after their birth. Contextual fear conditioning has no effect on the number of neurospheres or BrdU-labeled cells in the BLA, but produces an increase in hippocampal cell proliferation. These results demonstrate that neurogenic precursor cells are present in the adult BLA, and generate functional interneurons, but also show that their activity is not regulated by an amygdala-dependent learning paradigm.

Abstract
BACKGROUND The management of cancer is predicated on the availability and affordability of anticancer therapies, which may be either curative or noncurative. AIM The primary aims of the study were to evaluate (i) the formulary availability of licensed antineoplastic medicines across Europe; (ii) patient out-of-pocket costs for the medications and (iii) the actual availability of the medication for a patient with a valid prescription. MATERIALS AND METHODS The survey tool was based on the previous ESMO studies that addressed the availability and accessibility of opioids for the management of cancer pain. A total of 185 field reporters from 49 countries were invited to participate. The preliminary set of data was posted on the ESMO website for open peer-review, and amendments have been incorporated into the final report. RESULTS There are substantial differences in the formulary availability, out-of-pocket costs and actual availability for many anticancer medicines. The most profound lack of availability is in countries with lower levels of economic development, particularly in Eastern Europe, and these are largely related to the cost of targeted agents approved in the last 10 years. Discrepancies are less profound among medications on the WHO model essential medicines list (EML) for cancer and in curative settings. However, medicine shortages also affect WHO EML medicines, with relevant therapeutic implications for many patients. CONCLUSIONS The cost and affordability of anticancer treatments with recent market approval is the major factor contributing to inequity of access to anticancer medications. This is especially true with regards to new medications used in the management of EGFR- or ALK-mutated non-small-cell lung cancer, metastatic melanoma, metastatic renal cell cancer, RAS/RAF wild-type metastatic colorectal cancer, HER2 overexpressed breast cancer and castration-resistant metastatic prostate cancer.

Abstract
The Mars Science Laboratory rover Curiosity visited two active wind-blown sand dunes within Gale crater, Mars, which provided the first ground-based opportunity to compare Martian and terrestrial eolian dune sedimentary processes and study a modern analog for the Martian eolian rock record. Orbital and rover images of these dunes reveal terrestrial-like and uniquely Martian processes. The presence of grainfall, grainflow, and impact ripples resembled terrestrial dunes. Impact ripples were present on all dune slopes and had a size and shape similar to their terrestrial counterpart. Grainfall and grainflow occurred on dune and large-ripple lee slopes. Lee slopes were ~29° where grainflows were present and ~33° where grainfall was present. These slopes are interpreted as the dynamic and static angles of repose, respectively. Grain size measured on an undisturbed impact ripple ranges between 50 μm and 350 μm with an intermediate axis mean size of 113 μm (median: 103 μm). Dissimilar to dune eolian processes on Earth, large, meter-scale ripples were present on all dune slopes. Large ripples had nearly symmetric to strongly asymmetric topographic profiles and heights ranging between 12 cm and 28 cm. The composite observations of the modern sedimentary processes highlight that the Martian eolian rock record is likely different from its terrestrial counterpart because of the large ripples, which are expected to engender a unique scale of cross stratification. More broadly, however, in the Bagnold Dune Field as on Earth, dune-field pattern dynamics and basin-scale boundary conditions will dictate the style and distribution of sedimentary processes.

Abstract
The Mars Science Laboratory Curiosity rover performed coordinated measurements to examine the textures and compositions of aeolian sands in the active Bagnold dune field. The Bagnold sands are rounded to subrounded, very fine to medium sized (~45-500 μm) with ≥6 distinct grain colors. In contrast to sands examined by Curiosity in a dust-covered, inactive bedform called Rocknest and soils at other landing sites, Bagnold sands are darker, less red, better sorted, have fewer silt-sized or smaller grains, and show no evidence for cohesion. Nevertheless, Bagnold mineralogy and Rocknest mineralogy are similar with plagioclase, olivine, and pyroxenes in similar proportions comprising >90% of crystalline phases, along with a substantial amorphous component (35% ± 15%). Yet Bagnold and Rocknest bulk chemistry differ. Bagnold sands are Si enriched relative to other soils at Gale crater, and H2O, S, and Cl are lower relative to all previously measured Martian soils and most Gale crater rocks. Mg, Ni, Fe, and Mn are enriched in the coarse-sieved fraction of Bagnold sands, corroborated by visible/near-infrared spectra that suggest enrichment of olivine. Collectively, patterns in major element chemistry and volatile release data indicate two distinctive volatile reservoirs in Martian soils: (1) amorphous components in the sand-sized fraction (represented by Bagnold) that are Si-enriched, hydroxylated alteration products and/or H2O- or OH-bearing impact or volcanic glasses and (2) amorphous components in the fine fraction (<40 μm; represented by Rocknest and other bright soils) that are Fe, S, and Cl enriched with low Si and adsorbed and structural H2O.

Abstract
BACKGROUND The availability and affordability of safe, effective, high-quality, affordable anticancer therapies are a core requirement for effective national cancer control plans. METHOD Online survey based on a previously validated approach. The aims of the study were to evaluate (i) the availability on national formulary of licensed antineoplastic medicines across the globe, (ii) patient out-of-pocket costs for the medications, (iii) the actual availability of the medication for a patient with a valid prescription, (iv) information relating to possible factors adversely impacting the availability of antineoplastic agents and (v) the impact of the country's level of economic development on these parameters. A total of 304 field reporters from 97 countries were invited to participate. The preliminary set of data was posted on the ESMO website for open peer review and amendments have been incorporated into the final report. RESULTS Surveys were submitted by 135 reporters from 63 countries and additional peer-review data were submitted by 54 reporters from 19 countries. There are substantial differences in the formulary availability, out-of-pocket costs and actual availability for many anticancer medicines. The most substantial issues are in lower-middle- and low-income countries. Even among medications on the WHO Model List of Essential Medicines (EML) the discrepancies are profound and these relate to high out-of-pocket costs (in low-middle-income countries 32.0% of EML medicines are available only at full cost and 5.2% are not available at all, and for low-income countries, the corresponding figures are even worse at 57.7% and 8.3%, respectively). CONCLUSIONS There is wide global variation in formulary availability, out-of-pocket expenditures and actual availability for most licensed anticancer medicines. Low- and low-middle-income countries have significant lack of availability and high out-of-pocket expenditures for cancer medicines on the WHO EML, with much less availability of new, more expensive targeted agents compared with high-income countries.
