Abstract
The objective was to compare pregnancy per service event (P/S) in lactating dairy cows following timed artificial insemination (AI) or timed embryo transfer (ET) using either fresh or frozen in vitro-produced embryos. Oocytes were collected once per week for up to 9 wk using transvaginal ovum pick-up from elite dairy donors (ET-DAIRY; n = 40; Holstein-Friesian and Jersey) and elite beef donors (ET-ELITE-BEEF; n = 21; Angus). Both ET-DAIRY and ET-ELITE-BEEF donors consisted of heifers and cows. In addition, oocytes were collected from the ovaries of beef heifers of known pedigree following slaughter at a commercial abattoir (ET-COMM-BEEF; n = 119). Following in vitro maturation and fertilization, presumptive zygotes were cultured in vitro to the blastocyst stage. Grade 1 blastocysts were either transferred fresh or frozen for on-farm thawing and direct transfer. A total of 1,106 recipient cows (all lactating, predominantly Holstein-Friesian) located on 16 herdlets were blocked based on parity, calving date, and Economic Breeding Index, and randomly assigned to receive AI (n = 243) or ET (n = 863) after estrous synchronization with a 10-d Progesterone-synch protocol. Cows assigned to ET were further randomized to receive fresh (n = 187) or frozen (n = 178) ET-ELITE-BEEF embryos, fresh (n = 169) or frozen (n = 162) ET-DAIRY embryos, or fresh (n = 80) or frozen (n = 87) ET-COMM-BEEF embryos. Pregnancy was diagnosed using transrectal ultrasound on d 32 to 35 after synchronized ovulation and confirmed on d 62 to 65, at which time fetal sex was determined. Pregnancy per service event at d 32 was not different between AI (48.8%) and ET (48.9%) and did not differ between dairy and beef embryos (50.3% vs. 48.1%, respectively). However, P/S was less on d 32 following transfer of frozen embryos (41.6%) compared with fresh embryos (56.1%). Pregnancy loss between d 32 and 62 was greater for ET (15.1%) compared with AI (4.7%), with greater losses observed for frozen beef (18.5%), fresh beef (17.3%), and frozen dairy (19.2%) compared with fresh dairy (6.0%) embryos. Serum progesterone (P4) concentration on d 7 was associated with P/S at d 32 and 62. Cows in the quartile with the least serum P4 concentrations (quartile 1) had less probability of being pregnant on d 32 (33.4%) compared with cows in the 3 upper quartiles for serum P4 (45.7%, 55.6%, and 61.2% for quartile 2, quartile 3, and quartile 4, respectively). Sex ratio (male:female) at d 62 was skewed toward more male fetuses following ET (61.1:38.9) compared with AI (43.2:56.8) and was consistent with the sex ratio among in vitro blastocysts (61.2:38.8). In conclusion, P/S was similar for AI and ET, although pregnancy loss between d 32 and 62 was greater for ET than for AI.

Abstract
OBJECTIVE The purpose of this study was to apply contemporary consensus criteria developed by the Society for Cardiovascular Pathology and the Association for European Cardiovascular Pathology to the evaluation of aortic pathology, with the expectation that the additional pathologic information may enhance the understanding and management of aortic diseases. METHODS A scoring system was applied to ascending aortic specimens from 42 patients with heritable thoracic aortic disease and known genetic variations and from 86 patients from a single year, including patients with known genetic variations (n = 12) and patients with sporadic disease (n = 74). RESULTS The various types of lesions of medial degeneration and the overall severity of medial degeneration overlapped considerably between those patients with heritable disease and those with sporadic disease; however, patients with heritable thoracic aortic disease had significantly more overall medial degeneration (P = .004) and higher levels of elastic fiber fragmentation (P = .03) and mucoid extracellular matrix accumulation (P = .04) than patients with sporadic thoracic aortic disease. Heritable thoracic aortic disease with known genetic variation was more prevalent in women than in men (27.2% vs 9.8%; P = .04), and women had more severe medial degeneration than men (P = .04). Medial degeneration scores were significantly lower for patients with bicuspid aortic valves than for patients with tricuspid aortic valves (P = .03). CONCLUSION The study's findings indicate considerable overlap in the pattern, extent, and severity of medial degeneration between sporadic and hereditary types of thoracic aortic disease. This finding suggests that histopathologic medial degeneration represents the final common outcome of diverse pathogenetic factors and mechanisms.

Abstract
A multinational outbreak of nosocomial fusarium meningitis occurred among immunocompetent patients who had undergone surgery with epidural anesthesia in Mexico. The pathogen involved had a high predilection for the brain stem and vertebrobasilar arterial system and was associated with high mortality from vessel injury. Effective treatment options remain limited; in vitro susceptibility testing of the organism suggested that it is resistant to all currently approved antifungal medications in the United States. To highlight the severe complications associated with fusarium infection acquired in this manner, we report data, clinical courses, and outcomes from 13 patients in the outbreak who presented with symptoms after a median delay of 39 days.

Abstract
Asthma, which affects some 300 million people worldwide and caused 455,000 deaths in 2019, is a significant burden to suffers and to society. It is the most common chronic disease in children and represents one of the major causes for years lived with disability. Significant efforts are made by organizations such as WHO in improving the diagnosis, treatment and monitoring of asthma. However asthma prevention has been less studied. Currently there is a concept of pre- diabetes which allows a reduction in full blown diabetes if diet and exercise are undertaken. Similar predictive states are found in Alzheimer's and Parkinson's diseases. In this paper we explore the possibilities for asthma prevention, both at population level and also investigate the possibility of defining a state of pre-asthma, in which intensive treatment could reduce progression to asthma. Since asthma is a heterogeneous condition, this paper is concerned with allergic asthma. A subsequent one will deal with late onset eosinophilic asthma.

Abstract
Lack of exercise contributes to systemic inflammation and is a major cause of chronic disease. The long-term impact of initiating and sustaining exercise in late life, as opposed to sustaining a sedentary lifestyle, on whole-body health measures such as physical performance is not well known. This is an exploratory study to compare changes in physical performance among older adults initiating exercise late in life versus inactive older adults. Data from two observational cohorts were included in this analysis, representing two activity groups. The Active group cohort comprises older adults (n = 318; age 72.5 ± 7.2 years) enrolled in a supervised exercise program, "Gerofit." The inactive group comprises older adults (n = 146; age 74.5 ± 5.5 years) from the Italian study "Act on Ageing" (AOA) who self-reported being inactive. Participants in both groups completed physical performance battery at baseline and 1-year including: 6-min walk test, 30-s chair stand, and timed up-and-go. Two-sample t-tests measured differences between Gerofit and AOA at baseline and 1-year across all measures. Significant between-group effects were seen for all performance measures (ps = 0.001). The AOA group declined across all measures from baseline to 1 year (range -18% to -24% change). The Gerofit group experienced significant gains in function for all measures (range +10% to +31% change). Older adults who initiated routine, sustained exercise were protected from age-related declines in physical performance, while those who remained sedentary suffered cumulative deficits across strength, aerobic endurance, and mobility. Interventions to reduce sedentary behaviors and increase physical activity are both important to promote multi-system, whole-body health.

Abstract
Combined hepatocellular-cholangiocarcinoma (cHCC-CC) is a liver tumor with features of both hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC). It consists of intermingled malignant biliary and hepatic tissue and thus a distinct entity, rather than two separate coexisting malignancies. A 59-year-old female with a history of hepatitis C and cirrhosis presented with abdominal pain and altered mental status. She developed hematemesis, and despite extensive interventions, she expired one day after her initial presentation. At autopsy, the liver was diffusely and markedly fibrotic with numerous nodules of varying size with invasion into adjacent vasculature. Microscopic examination of the nodules revealed cHCC-CC with stem cell features, lymphovascular invasion, and tumor emboli scattered throughout the right lung. The patient had end-stage liver disease due to the accumulation of damage and consequent fibrosis. This led to portal hypertension with subsequent massive gastrointestinal bleeding, hemorrhagic shock, and death. cHCC-CC is a rare, aggressive primary liver tumor with a poor prognosis. It can present with a cirrhotomemetic pattern with small nodules that can evade clinical and radiographic detection. Autopsy findings can provide valuable insights into the pathogenesis and clinical course of cHCC-CC, highlight the aggressive nature of the disease, and may inform future diagnostic and therapeutic strategies. Accurate diagnosis of this tumor is important for patient management and prognostication.

Abstract
Background The COVID-19 pandemic created new difficulties for people living with brain injury, their families, and caregivers while amplifying the challenges of community-based associations that support them. We aimed to understand the effects of the pandemic on clients who live with brain injury, as well as on the provision of community brain injury services/programs in Canada. Methods Online cross-sectional survey conducted in January 2022. Representatives of brain injury associations across Canada completed the 31 open- and closed-ended questions about meeting clients' needs, addressing public health guidelines, and sustaining the association. Data were analyzed using descriptive statistics (close-ended questions) and qualitative content analysis (open-ended questions). Results Of the 45 key representatives from associations in Pacific/Western (40%), Central (56%), and Atlantic Canada (4%), the majority were paid executive directors (67%). Participants reported that the most frequent psychosocial challenges experienced by their clients during the pandemic were social isolation (98%), loneliness (96%), and anxiety (93%). To alleviate these challenges, associations implemented wellness checks and psychosocial support. Most respondents (91%) affirmed that clients faced multiple technological barriers, such as a lack of technological knowledge and financial resources for devices and/or internet. In the open-ended questions, twenty-nine (64%) associations reported providing clients with devices, technology training, and assistance. Regarding public health measures, thirty (67%) respondents reported that clients had challenges understanding and/or following public health guidelines. Forty-two associations (93%) provided tailored information to help clients understand and comply with public health measures. Although associations (67%) received pandemic-related funding from the Canadian government they still struggled with the association's sustainability. Thirty-four (76%) lost funding or financial resources that prevented them from delivering programs or required the use of reserve funds to continue to do so. Only 56% reported receiving sufficient funding to address additional COVID-19-related expenses. Conclusion Although the pandemic added further challenges to the sustainability of brain injury associations across Canada, they quickly adapted services/programs to respond to the increasing and varied needs of clients, while complying with protective measures. To ensure community associations' survival it is essential to aptly recognize the vital role played by these associations within the brain injury care continuum.

Abstract
The blood-brain barrier (BBB) presents a significant challenge for targeted drug delivery. A proposed method to improve drug delivery across the BBB is focused ultrasound (fUS), which delivers ultrasound waves to a targeted location in the brain and is hypothesized to open the BBB. Furthermore, stem cell-derived exosomes have been suggested as a possible anti-inflammatory molecule that may have neural benefits, if able to pass the BBB. In the present study, transcranial low-intensity focused ultrasound (LIFU), without the use of intravenous microbubbles, was assessed for both (1) its ability to influence the BBB, as well as (2) its ability to increase the localization of intravenously administered small molecules to a specific region in the brain. In vivo rat studies were conducted with a rodent-customized 2 MHz LIFU probe (peak pressure = 1.5 MPa), and injection of labeled stem cell-derived exosomes. The results suggested that LIFU (without microbubbles) did not appear to open the BBB after exposure times of 20, 40, or 60 min; instead, there appeared to be an increase in transcytosis of the dextran tracer. Furthermore, the imaging results of the exosome study showed an increase in exosome localization in the right hippocampus following 60 min of targeted LIFU.

Abstract
The role of allograft nephrectomy (AN) in failed renal transplants is a topic of debate, owing to controversial results reported in the literature and the fact that most of the studies are limited by a retrospective design and small numbers of participants. Allograft nephrectomy is most likely of benefit in the patient with recurrent allograft intolerance syndrome (AIS) following pulse steroids. Immunosuppression weaning in the presence of clinical signs related to a chronic inflammatory state is also reasonable grounds to pursue AN. Studies are mainly inconclusive but suggest that AN has no overall benefit for allograft survival after retransplant. This topic is still of interest in the transplant field and is particularly relevant for patients who are likely to require retransplantation within their lifetime. Further assessment is needed in the form of randomized controlled trials that control for various AN indications and immunosuppression regimens, and have clearly defined survival outcomes.

Abstract
The COVID-19 pandemic has increased challenges for people living with brain injury and community associations to support this vulnerable population. This study aimed to gain an in-depth understanding of the challenges faced by brain injury survivors during the first year of the pandemic and how community brain injury associations adapted their services to respond to these needs. Findings from seven focus-group with 31 representatives of Canadian brain injury associations revealed 4 main themes: (1) Addressing evolving client needs; (2) Keeping clients safe; (3) Challenges and opportunities navigating the digital world; and (4) Sustaining brain injury associations in the face of uncertainties and disruptions. To comply with public health measures, associations reported pivoting their service delivery online, despite recognizing the difficulties this could create for many brain injury survivors in accessing and using technology. Our findings also highlight concrete directions for not-profit organizations providing instrumental help with activities, acting as a liaison and interpreter of public health guidelines, and in connecting with clients using technology while handling potential cognitive and technological challenges. Addressing these issues has the potential to protect people living with brain injury and community associations from external threats, like pandemics, in the future.

Abstract
Obesity is a common chronic disorder and has detrimental long-term consequences if left untreated. Herein, we report a case of a young lady who suffered from morbid obesity and many of its consequences, and we present a literature review of these complications. While the cause of obesity is multifactorial, the genetic component is particularly important in the pathophysiology of marked obesity. Resistance to Leptin is considered one of the main causes of obesity. There is a unique relationship between polycystic ovary syndrome and obesity, as observed in our case. Obesity is associated with cardiovascular and lung diseases such as heart failure, thromboembolic disease, sleep apnea, and pulmonary hypertension. Our patient had cardiomegaly (730 gm) with eccentric hypertrophy of left and right ventricles. The coronary arteries and aorta were free of atherosclerosis, which is a surprising finding that relates to the mysterious phenomenon of obesity paradox. The terminal event in our young woman was multiple segmental and subsegmental pulmonary arterial thrombi/thromboemboli superimposed on chronic cardiopulmonary stress due to massive obesity.

Abstract
The aim was to examine the effect of sire fertility status on conceptus-induced changes in the bovine endometrial transcriptome. To generate elongated conceptuses, Day 7 blastocysts produced in vitro using frozen-thawed sperm from Holstein Friesian bulls (3 High fertility, HF and 3 Low fertility, LF) were transferred in groups of 5–10 into synchronized heifers (n = 7 heifers per bull) and recovered following slaughter on Day 15. Day 15 endometrial explants recovered from the uterine horn ipsilateral to the corpus luteum were recovered from synchronized cyclic heifers (n = 4). Explants from each heifer were co-cultured for 6 h in RPMI medium alone (Control) or with 100 ng/ml ovine recombinant interferon tau (IFNT) or with a single conceptus from each HF or LF bull. After 6 h, explants were snap frozen and stored at −80°C. Extracted mRNA was subjected to RNA-seq and the resulting data were analyzed with R software. The numbers of differentially expressed genes (DEG; FDR<0.05) were: HF vs. Control: 956; LF vs. Control: 1021; IFNT vs. Control: 1301; HF vs. LF: 2. Unsurprisingly, the majority of DEG (658) were common to all comparisons and were related to IFNT-induced changes in the endometrium. Prior to applying the adjusted p-value, there were 700 DEG between HF and LF, with 191 and 509 genes more expressed in HF or LF, respectively (p < 0.05). Overrepresentation analysis of KEGG pathways (FDR<0.05), revealed that DEG with higher expression in LF were involved in cell cycle and proteolysis, while those upregulated DEG by HF conceptuses were strongly associated with immune process pathways, such as TNF, NF-kappa B, cytokine-cytokine receptor interaction, and TLR signaling. These pathways were also enriched by DEG upregulated by IFNT compared to the Control. Furthermore, only the HF, and not the LF group, affected the expression of most genes in these pathways (p < 0.05) according to a negative binomial regression model. Finally, a weighted gene co-expression network analysis revealed two clusters of co-expressed genes associated with the HF conceptuses (p < 0.05), which were also enriched for the aforementioned pathways. In conclusion, HF conceptuses, similar to IFNT treatment, stimulated multiple pathways involved in immune response, which were apparently not affected by LF conceptuses.

Abstract
We present preliminary results from an on-going program that aims at mapping the intracluster medium (ICM) temperature of high redshift galaxy clusters from the MaDCoWS sample using a joint analysis of shallow X-ray data obtained by Chandra and high angular resolution Sunyaev-Zel’dovich (SZ) observations realized with the NIKA2 and MUSTANG-2 cameras. We also present preliminary results from an on-going Open Time program within the NIKA2 collaboration that aims at mapping the ICM temperature of a galaxy cluster at z = 0.45 from the resolved detection of the relativistic corrections to the SZ spectrum. These studies demonstrate how high angular resolution SZ observations will play a major role in the coming decade to push the investigation of ICM dynamics and non-gravitational processes to high redshift before the next generation X-ray observatories come into play.

Abstract
Abstract
Background
For quality improvement to be assessed in a healthcare setting, understanding the specific patient profile is vital. Only then can system performance and service development be reviewed accurately. The purpose of this review was to analyse the patient profile of a 20 bed older persons rehabilitation unit.
Methods
Data was collected weekly for patients admitted and discharged to a sub-acute rehabilitation unit over a six month period (January to June 2021) by a multi-disciplinary team (MDT). Information collected included; age, clinical frailty scale (CFS, revised 2008, Rockwood et al., 2005), MDT involvement, care needs on discharge, onward community referrals and length of stay.
Results
62 patients were included (25 males and 37 females) with an average age of 81 (range 61–99). The CFS was measured for 58 patients and ranged from 1 to 7. On examination, 9% of patients had a CFS of 1–2, 38% a CFS of 3–4, 46% a CFS of 5–6 and 7% a CFS of 7.
Of the 62 patients included, all received physiotherapy and occupational therapy, 28 speech and language therapy, 25 dietetics and 48 medical social work.
The average length of stay was 42 days (range 10–162).
On discharge 42% of patients went home with existing supports, 50% went home with increased supports and 8% went to a residential care facility. Referrals to community services were sent for 65% of patients.
Conclusion
53% of patients admitted to an older person rehabilitation unit had a CFS of 5 or more, indicating they were at least mildly frail. The average length of stay was six weeks and all patients required a minimum of two MDT members during their stay. This highlights the presence of frailty and the importance of effective MDT working in the sub-acute rehabilitation setting.

Abstract
Abstract
Background
The mission of an older person’s sub-acute rehabilitation unit is to improve the individual’s function and quality of life. This is achieved through patient and multidisciplinary team (MDT) collaboration. The MDT collect Therapy Outcome Measure (TOM) (Enderby and John 2015) data to measure the effectiveness of rehabilitation and facilitate analysis of patient and service outcomes. This abstract will present 6 months of data collection with the aim of evaluating the impact of MDT intervention from January 2021.
Methods
The MDT meet weekly to jointly record patient TOM scores on admission and discharge. The TOM scales used are; multifactorial conditions, stroke and neurological disorder. The patient is scored from 0–5 in four domains; impairment, activity, participation and well-being. There are 11 parts to the scale with 0.5 scores permitted (Enderby and John 2015).
Results
Data was analysed on 62 patients. Across an episode of rehabilitation an increase of 0.5 or more on the TOM is a clinically significant (positive) change. 84% of patients had an overall improvement in the total TOM score. There was an average overall increase of 2.6 points on the scale which equates to a 25% overall change. 63% improved in the domain of impairment, 77% in activity, 73% in participation and 66% in wellbeing. 100% of patients post-stroke, 81% with multifactorial conditions and 75% with neurological conditions experienced an overall improvement.
Conclusion
The data objectively shows positive patient outcomes in older persons rehabilitation. Individuals experienced the most positive change in their activity and participation function and high levels of change are also evident in impairment levels and well-being. Overall, TOM is a very useful MDT outcome measure tool. It has been successfully implemented and maintained in the service and facilitates the ongoing analysis of individual and service outcomes to understand the impact of intervention.

Abstract
Perioperative pain management is an important consideration in early recovery and patient satisfaction following laparoscopic donor nephrectomy. Transmuscular quadratus lumborum block has been described to reduce pain and opioid usage following several abdominal surgeries. In this prospective single‐blind randomized controlled trial, we compared 52 patients who adhered to our institutional donor nephrectomy Early Recovery After Surgery pathway, which includes a laparoscopic‐guided transversus abdominus plane block, to 40 patients who additionally received a transmuscular quadratus lumborum block with liposomal bupivacaine. Compared to control patients, those who received the block spent longer in the operating room prior to the surgical start (65.4 vs. 51.6 min, P < .001). Both groups had similar total hospital length of stay (33.3 h vs. 34.4 h, P = .61). Pain scores from postoperative days 0–30, number of patients requiring opioids, postoperative nausea, and pain management satisfaction were similar between both groups. Patients who received the block consumed less opioid on postoperative day 1 compared to controls (P = .006). No complications were attributable to the block. The quadratus lumborum block provides a safe pain management adjunct for some patients, and may reduce opioid use in the early postoperative period when combined with our standard institutional protocol for kidney donors.

Abstract
Despite passing routine laboratory tests of semen quality, bulls used in artificial insemination (AI) exhibit a significant range in field fertility. The objective of this study was to determine whether subfertility in AI bulls is due to issues of sperm transport to the site of fertilization, fertilization failure, or failure of early embryo or conceptus development. In experiment 1, Holstein-Friesian bulls (3 high fertility, HF, and 3 low fertility, LF) were selected from the national population of AI bulls based on adjusted fertility scores from a minimum of 500 inseminations (HF: +4.37% and LF: -12.7%; mean = 0%). Superovulated beef heifers were blocked based on estimated number of follicles at the time of AI and inseminated with semen from HF or LF bulls (n = 3-4 heifers per bull; total 19 heifers). Following slaughter 7 d later, the number of corpora lutea was counted and the uteri were flushed. Recovered structures (oocytes/embryos) were classified according to developmental stage and stained with 4',6-diamidino-2-phenylindole to assess number of cells and accessory sperm. Overall recovery rate (total structures recovered/total corpora lutea) was 52.6% and was not different between groups. Mean (± standard error of the mean) number of embryos recovered per recipient was 8.7 ± 5.2 and 9.4 ± 5.5 for HF and LF, respectively. Overall fertilization rate of recovered structures was not different between groups. However, more embryos were at advanced stages of development (all blastocyst stages combined), reflected in a greater mean embryo cell number on d 7 for HF versus LF bulls. Number of accessory sperm was greater for embryos derived from HF than for LF bulls. The aim of experiment 2 was to evaluate the effect of sire fertility on survival of bovine embryos to d 15. Day 7 blastocysts were produced in vitro using semen from the same HF (n = 3) and LF (n = 3) bulls and transferred in groups of 5-10 to synchronized heifers (n = 7 heifers per bull; total 42 heifers). Conceptus recovery rate on d 15 was higher in HF (59.4%,) versus LF (45.0%). Mean length of recovered conceptuses for HF bulls was not affected by fertility status. In conclusion, while differences in field fertility among AI sires used in this study were not reflected in fertilization rate, differences in embryo quality were apparent as early as d 7. These differences likely contributed to the higher proportion of conceptuses surviving to d 15 in HF bulls.

Abstract
Abstract
Dormancy is an elusive and deadly component of cancers. Rare, therapy resistant cells lay dormant for decades and when reactivated cause disease progression and relapse. Eradicating dormant cancer cells is key to curing cancers yet is an unrealized goal. The skeleton remains a common location for dissemination and dormancy, yet our understanding of the cellular and molecular pathways that control dormant cancer cells in the the skeleton is limited. We hypothesized that dormant cancer cells occupy a common niche in the skeleton and this supports long-term dormancy. To test this we developed technology to identify and analyse dormant cancers cells from different cancer types and the compartment in the skeleton in which they reside. Membrane label retention was able to distinguish dormant cancer cells from reactivated cancer cells. Intravital imaging showed that dormant cancer cells were found associated with endosteal bone surface suggesting that different cancers may occupy a common niche. Single cell RNA sequencing of dormant cancer cells showed they expressed a distinct gene signature that was enriched for myeloid genes. Single cell RNA sequencing of >130,000 cells isolated from the endosteal bone compartment and the bone marrow identified 32 distinct cell clusters. Detailed transcriptional analysis facilitated construction of a map of all of the cell types/states present in the endosteal bone compartment. In silico ligand/receptor interaction mapping enabled identification of the cell types and the molecular pathways that may mediate dormant cell niche formation in vivo. Non-haemopoietic cells, particularly cells of the osteoblast lineage and endothelia cells were the most enriched for dormant cell binding partners. This was common across three different dormant tumor types. Detailed analysis of cells of the osteoblast lineage showed greatest enrichment for binding partners in LeprHigh/Cxcl12High mesenchymal cells. Further analysis of the molecular pathways that can interact with binding partners identified a number of potential molecular regulators of dormancy. For example, Gas6, which is expressed by LeprHigh/Cxcl12High mesenchymal cells, has the binding partners Axl expressed by dormant myeloma cells, Mertk in dormant breast cancer cells and Mertk and Tyro3 in dormant prostate cancer. Treatment of mice bearing myeloma cells with small molecule inhibitors of Axl reduced dormant cells and increased tumor burden suggesting the Axl/Gas6 interaction is functional important in controlling dormancy. Together these data show that single cell sequencing can be used to define the cells and molecular pathways that facilitate dormant cancer cell niche formation in the skeleton. This approach suggests that that cancer cell specific molecules interact with common molecules in the endosteal niche, including LeprHigh/Cxcl12High mesenchymal cells, to switch on common molecular pathways to control dormancy.

Abstract
Maternal nutritional perturbation during gestation influences fetal development which, in turn, can affect postnatal growth, gonad development, gamete quality, and health of the offspring. The objective of this study was to determine whether maternal diet during the pre-pubertal phase would induce modifications in future male fetal reproductive development. Angus×Holstein-Friesian heifers (n=80) with a mean (±s.d.) age of 141±8d and bodyweight (BW) of 119±23kg had unrestricted access to a perennial ryegrass dominated sward supplemented with either 0.5kg of concentrate daily to achieve an average daily gain (ADG) of 0.50kg (moderate, MOD) or concentrate ad libitum to achieve an ADG of >1.0kg (high, HI). Heifers were offered these divergent dietary regimens from 4.5 to 8.5 months of age, after which they were all offered a moderate plane of nutrition. Heifers were bred to a synchronised oestrus at a mean age of 502±8.2d and mean BW of 360±46.7kg using semen from a single proven sire. Transrectal uterine ultrasonography was carried out 63 days post-AI to determine pregnancy and fetal sex; a cohort of heifers reflective of group average BW and age and carrying male fetuses were slaughtered on Day 100 of gestation (HI: n=10; MOD: n=12). Fetal crown–rump length and weight were recorded. One testis was snap frozen for RNA sequencing and the other was processed for stereology. Mean (±s.d.) fetal crown–rump length and weight were 19.5±0.69cm and 314.6±33.6g, respectively, and did not differ between groups. RNA sequencing revealed 45 differentially expressed genes (DEGs) between groups, 44 of which were upregulated in the HI group. A total of 29 biochemical pathways were identified as significantly enriched (P<0.05), six of which were predicted to be involved in the development of the reproductive tract based on several DEGs. Histological analysis revealed greater (P<0.05) fetal testicular interstitial tissue density in the MOD group and a strong tendency towards increased seminiferous tubule density (P=0.06) in the HI group. In conclusion, offering a high plane of nutrition during the prepubertal period not only increases the rate of sexual development in the heifer but also induces latent in utero modifications to the testicular development of their subsequent male progeny. The consequences for postnatal development of male progeny remain to be elucidated.

Abstract
Background: Gerofit, an exercise program for older Veterans, is undergoing national dissemination (17 sites in 6 years). Four sites have accrued 4-year functional outcomes (gait speed, 8-foot-up-and-go, 30-second chair stand, and six-minute walk). Methods: Functional assessments were administered quarterly in first year and annually thereafter. Individuals with baseline and at least two follow up measures were included for analysis (n=587). Means were gathered across each timepoint. Results: Mean values for functional assessments from baseline to 4 year were as follows: gait speed m/s- 1.04, 1.12, 1.13, 1.13, 1.09, 1.07, 1.13; 8 ft-up-and-go seconds- 7.6, 6.82, 6.69, 6.69, 7.29, 7.29, 7.51; 30 second chair stands 11.88, 14.06, 14.72, 14.89, 14.69, 14.71, 14.96; and six-minute-walk yards- 499, 532, 541, 544, 531, 530, 556. All follow up measures were significantly improved over baseline (P<.01) and superior to normative age-related decline. Implications: Results indicate that exercise promotes compression of morbidity and improved functional health.

Abstract
Since March 2019, E-cigarette or Vaping product associated lung injury (EVALI) has become an ongoing epidemic with more 2600 cases reported in the span of a few months in the United States. EVALI is defined as acute lung injury that develops secondary to the use of e-cigarettes or vaping products within the previous 90 days after exlusion of other possible inciting factors. Vitamin E acetate is believed to play a significant role in its pathogenesis. Treatment involves use of corticosteroids and further avoidance of these products. We describe a case series of 8 patients with EVALI, their clinical course and outcomes. All patients showed an excellent response to corticosteroids. In our experience, prognosis of EVALI is excellent, with complete resolution of symptoms in patients who followed up at 8 weeks.

Abstract
This paper collates the pathological findings from initial published autopsy reports on 23 patients with coronavirus disease 2019 (COVID-19) from 5 centers in the United States of America, including 3 cases from Houston, Texas. Findings confirm that COVID-19 is a systemic disease with major involvement of the lungs and heart. Acute COVID-19 pneumonia has features of a distinctive acute interstitial pneumonia with a diffuse alveolar damage component, coupled with microvascular involvement with intra- and extravascular fibrin deposition and intravascular trapping of neutrophils, and, frequently, with formation of microthombi in arterioles. Major pulmonary thromboemboli with pulmonary infarcts and/or hemorrhage occurred in 5 of the 23 patients. Two of the Houston cases had interstitial pneumonia with diffuse alveolar damage pattern. One of the Houston cases had multiple bilateral segmental pulmonary thromboemboli with infarcts and hemorrhages coupled with, in nonhemorrhagic areas, a distinctive interstitial lymphocytic pneumonitis with intra-alveolar fibrin deposits and no hyaline membranes, possibly representing a transition form to acute fibrinous and organizing pneumonia. Multifocal acute injury of cardiac myocytes was frequently observed. Lymphocytic myocarditis was reported in 1 case. In addition to major pulmonary pathology, the 3 Houston cases had evidence of lymphocytic pericarditis, multifocal acute injury of cardiomyocytes without inflammatory cellular infiltrates, depletion of splenic white pulp, focal hepatocellular degeneration and rare glomerular capillary thrombosis. Each had evidence of chronic cardiac disease: hypertensive left ventricular hypertrophy (420 g heart), dilated cardiomyopathy (1070 g heart), and hypertrophic cardiomyopathy (670 g heart). All 3 subjects were obese (BMIs of 33.8, 51.65, and 35.2 Kg/m2). Overall, the autopsy findings support the concept that the pathogenesis of severe COVID-19 disease involves direct viral-induced injury of multiple organs, including heart and lungs, coupled with the consequences of a procoagulant state with coagulopathy.

Abstract
BACKGROUND The introduction of antimicrobial surfaces into healthcare environments is believed to impact positively on the rate of healthcare-associated infections by significantly decreasing pathogen presence on surfaces. AIM To report on a novel efficacy test that uses a dry bacterial inoculum to measure the microbicidal efficacy of antimicrobial surfaces. METHODS An aerosolized dry inoculum of Staphylococcus aureus or Acinetobacter baumannii was deposited on copper alloy surfaces or a hospital-grade stainless-steel surface. Surviving bacteria were enumerated following incubation of the inoculated surfaces at an environmentally relevant temperature and relative humidity. Damage caused to bacteria by the aerosolization process and by the different surfaces was investigated. FINDINGS Dry inoculum testing showed a <2-log10 reduction in S. aureus or A. baumannii on the copper alloy surfaces tested after 24 h at 20°C and 40% relative humidity. Potential mechanisms of action included membrane damage, DNA damage and arrested cellular respiration. The aerosolization process caused some damage to bacterial cells. Once this effect was taken into account, the antimicrobial activity of copper surfaces was evident. CONCLUSIONS Our test provided a realistic deposition of a bacterial inoculum to a surface and, as such, a realistic protocol to assess the efficacy of dry antimicrobial environmental surfaces in vitro.

Abstract
Childhood dilated cardiomyopathy (DCM) is a leading cause of heart failure requiring cardiac transplantation and approximately 5% of cases result in sudden death. Knowledge of the underlying genetic cause can aid prognostication and clinical management and enables accurate recurrence risk counselling for the family. Here we used genomic sequencing to identify the causative genetic variant(s) in families with children affected by severe DCM. In an international collaborative effort facilitated by GeneMatcher, biallelic variants in PPP1R13L were identified in seven children with severe DCM from five unrelated families following exome or genome sequencing and inheritance-based variant filtering. PPP1R13L encodes inhibitor of apoptosis-stimulating protein of p53 protein (iASPP). In addition to roles in apoptosis, iASPP acts as a regulator of desmosomes and has been implicated in inflammatory pathways. DCM presented early (mean: 2 years 10 months; range: 3 months-9 years) and was progressive, resulting in death (n = 3) or transplant (n = 3), with one child currently awaiting transplant. Genomic sequencing technologies are valuable for the identification of novel and emerging candidate genes. Biallelic variants in PPP1R13L were previously reported in a single consanguineous family with paediatric DCM. The identification here of a further five families now provides sufficient evidence to support a robust gene-disease association between PPP1R13L and severe paediatric DCM. The PPP1R13L gene should be included in panel-based genetic testing for paediatric DCM.

Abstract
The latency associated with bone metastasis emergence in castrate-resistant prostate cancer is attributed to dormancy, a state in which cancer cells persist prior to overt lesion formation. Using single-cell transcriptomics and ex vivo profiling, we have uncovered the critical role of tumor-intrinsic immune signaling in the retention of cancer cell dormancy. We demonstrate that loss of tumor-intrinsic type I IFN occurs in proliferating prostate cancer cells in bone. This loss suppresses tumor immunogenicity and therapeutic response and promotes bone cell activation to drive cancer progression. Restoration of tumor-intrinsic IFN signaling by HDAC inhibition increased tumor cell visibility, promoted long-term antitumor immunity, and blocked cancer growth in bone. Key findings were validated in patients, including loss of tumor-intrinsic IFN signaling and immunogenicity in bone metastases compared to primary tumors. Data herein provide a rationale as to why current immunotherapeutics fail in bone-metastatic prostate cancer, and provide a new therapeutic strategy to overcome the inefficacy of immune-based therapies in solid cancers.
