Effects of CB1R inverse agonist, INV-202, in patients with features of metabolic syndrome. A randomized, placebo-controlled, double-blind phase 1b study. Diabetes Obes Metab 2024; 26:642-649. [PMID: 37941317 DOI: 10.1111/dom.15353] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Revised: 10/05/2023] [Accepted: 10/16/2023] [Indexed: 11/10/2023]
Abstract
AIMS To evaluate the clinical safety, tolerability, and pharmacokinetic and pharmacodynamic profile of the novel cannabinoid receptor-1 (CB1R) inverse agonist, INV-202, in adults with features of metabolic syndrome. MATERIALS AND METHODS This was a multicentre, randomized, double-blind, placebo-controlled, 28-day repeat-dose (INV-202 [25 mg] or placebo, once-daily oral tablet), parallel-group study in 37 participants aged 18 to 65 years (46% female, mean age 55 years, glycated haemoglobin 5.7% [39 mmol/mol], body mass index [BMI] 38.1 kg/m2 ) with features of metabolic syndrome and glucose intolerance. An oral glucose tolerance test (OGTT) was performed at baseline and at the end of the study. Lipid profiles, weight, waist circumference and biomarkers were assessed weekly. Statistical comparisons were performed post hoc. RESULTS INV-202 was well tolerated with no serious or severe treatment-emergent adverse events; the most common events related to known effects of CB1R blockade in the gastrointestinal tract. INV-202 produced a significant mean weight loss of 3.5 kg (3.3% compared with placebo participants who gained a mean 0.6 kg [0.5%]). INV-202 also exhibited significant reductions in waist circumference and BMI (P ≤ 0.03). There was no significant difference in OGTT 0- to 3-hour area under the curve for INV-202 versus placebo: least squares mean 29.38 versus 30.25 h*mmol/L, with an INV-202: placebo ratio of 97.1% (95% confidence interval 90.2, 105.6; P = 0.43). CONCLUSIONS INV-202 was well tolerated, producing a signal for rapid weight loss with improvements in other metabolic syndrome markers in this population. These findings support further exploration and long-term assessment of cardiometabolic effects.

Abstract
Periprosthetic joint infection (PJI) following revision total knee arthroplasty (TKA) for aseptic failure is associated with poor outcomes, patient morbidity, and high health care expenditures. The aim of this study was to develop novel machine learning algorithms for the prediction of PJI following revision TKA for patients with aseptic indications for revision surgery. A single-institution database consisting of 1,432 consecutive revision TKA patients with aseptic etiologies was retrospectively identified. The patient cohort included 208 patients (14.5%) who underwent re-revision surgery for PJI. Three machine learning algorithms (artificial neural networks, support vector machines, k-nearest neighbors) were developed to predict this outcome and these models were assessed by discrimination, calibration, and decision curve analysis. This is a retrospective study. Among the three machine learning models, the neural network model achieved the best performance across discrimination (area under the receiver operating characteristic curve = 0.78), calibration, and decision curve analysis. The strongest predictors for PJI following revision TKA for aseptic reasons were prior open procedure prior to revision surgery, drug abuse, obesity, and diabetes. This study utilized machine learning as a tool for the prediction of PJI following revision TKA for aseptic failure with excellent performance. The validated machine learning models can aid surgeons in patient-specific risk stratifying to assist in preoperative counseling and clinical decision making for patients undergoing aseptic revision TKA.

A multi-taxon analysis of European Red Lists reveals major threats to biodiversity. PLoS One 2023; 18:e0293083.

Abstract
Biodiversity loss is a major global challenge and minimizing extinction rates is the goal of several multilateral environmental agreements. Policy decisions require comprehensive, spatially explicit information on species' distributions and threats. We present an analysis of the conservation status of 14,669 European terrestrial, freshwater and marine species (ca. 10% of the continental fauna and flora), including all vertebrates and selected groups of invertebrates and plants. Our results reveal that 19% of European species are threatened with extinction, with higher extinction risks for plants (27%) and invertebrates (24%) compared to vertebrates (18%). These numbers exceed recent IPBES (Intergovernmental Platform on Biodiversity and Ecosystem Services) assumptions of extinction risk. Changes in agricultural practices and associated habitat loss, overharvesting, pollution and development are major threats to biodiversity. Maintaining and restoring sustainable land and water use practices is crucial to minimize future biodiversity declines.

Multiorgan MRI findings after hospitalisation with COVID-19 in the UK (C-MORE): a prospective, multicentre, observational cohort study. THE LANCET. RESPIRATORY MEDICINE 2023; 11:1003-1019. [PMID: 37748493 PMCID: PMC7615263 DOI: 10.1016/s2213-2600(23)00262-x] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/08/2023] [Revised: 06/16/2023] [Accepted: 06/30/2023] [Indexed: 09/27/2023]
Abstract
INTRODUCTION The multiorgan impact of moderate to severe coronavirus infections in the post-acute phase is still poorly understood. We aimed to evaluate the excess burden of multiorgan abnormalities after hospitalisation with COVID-19, evaluate their determinants, and explore associations with patient-related outcome measures. METHODS In a prospective, UK-wide, multicentre MRI follow-up study (C-MORE), adults (aged ≥18 years) discharged from hospital following COVID-19 who were included in Tier 2 of the Post-hospitalisation COVID-19 study (PHOSP-COVID) and contemporary controls with no evidence of previous COVID-19 (SARS-CoV-2 nucleocapsid antibody negative) underwent multiorgan MRI (lungs, heart, brain, liver, and kidneys) with quantitative and qualitative assessment of images and clinical adjudication when relevant. Individuals with end-stage renal failure or contraindications to MRI were excluded. Participants also underwent detailed recording of symptoms, and physiological and biochemical tests. The primary outcome was the excess burden of multiorgan abnormalities (two or more organs) relative to controls, with further adjustments for potential confounders. The C-MORE study is ongoing and is registered with ClinicalTrials.gov, NCT04510025. FINDINGS Of 2710 participants in Tier 2 of PHOSP-COVID, 531 were recruited across 13 UK-wide C-MORE sites. After exclusions, 259 C-MORE patients (mean age 57 years [SD 12]; 158 [61%] male and 101 [39%] female) who were discharged from hospital with PCR-confirmed or clinically diagnosed COVID-19 between March 1, 2020, and Nov 1, 2021, and 52 non-COVID-19 controls from the community (mean age 49 years [SD 14]; 30 [58%] male and 22 [42%] female) were included in the analysis. Patients were assessed at a median of 5·0 months (IQR 4·2-6·3) after hospital discharge. Compared with non-COVID-19 controls, patients were older, living with more obesity, and had more comorbidities. Multiorgan abnormalities on MRI were more frequent in patients than in controls (157 [61%] of 259 vs 14 [27%] of 52; p<0·0001) and independently associated with COVID-19 status (odds ratio [OR] 2·9 [95% CI 1·5-5·8]; padjusted=0·0023) after adjusting for relevant confounders. Compared with controls, patients were more likely to have MRI evidence of lung abnormalities (p=0·0001; parenchymal abnormalities), brain abnormalities (p<0·0001; more white matter hyperintensities and regional brain volume reduction), and kidney abnormalities (p=0·014; lower medullary T1 and loss of corticomedullary differentiation), whereas cardiac and liver MRI abnormalities were similar between patients and controls. Patients with multiorgan abnormalities were older (difference in mean age 7 years [95% CI 4-10]; mean age of 59·8 years [SD 11·7] with multiorgan abnormalities vs mean age of 52·8 years [11·9] without multiorgan abnormalities; p<0·0001), more likely to have three or more comorbidities (OR 2·47 [1·32-4·82]; padjusted=0·0059), and more likely to have a more severe acute infection (acute CRP >5mg/L, OR 3·55 [1·23-11·88]; padjusted=0·025) than those without multiorgan abnormalities. Presence of lung MRI abnormalities was associated with a two-fold higher risk of chest tightness, and multiorgan MRI abnormalities were associated with severe and very severe persistent physical and mental health impairment (PHOSP-COVID symptom clusters) after hospitalisation. INTERPRETATION After hospitalisation for COVID-19, people are at risk of multiorgan abnormalities in the medium term. Our findings emphasise the need for proactive multidisciplinary care pathways, with the potential for imaging to guide surveillance frequency and therapeutic stratification.

Progressing Towards Same-Day Discharges After Robotic-Assisted Radical Prostatectomy; Safe and Cost Effective to Discharge Without Routine Blood Tests. Res Rep Urol 2023; 15:471-477. [PMID: 37842030 PMCID: PMC10575481 DOI: 10.2147/rru.s429819] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Accepted: 09/28/2023] [Indexed: 10/17/2023] Open
Abstract
Introduction Changing population demographics and the recent SARS-CoV-2 pandemic have forever changed healthcare, with increasing demands on straining systems. The economic cost is yet to be fully realised, with growing concerns around the current system's ability to accommodate the ageing comorbid population. Consequently, a paradigm shift has taken place in healthcare systems, prioritizing cost accountability. In the absence of established guidelines or robust literature, the use of laboratory tests postoperatively is often guided solely by clinician preference. This study presents a retrospective analysis that investigates the utility and cost implications of routine postoperative investigation following robotic-assisted radical prostatectomies. The findings aim to emphasise the importance of evidence-based practices and cost-effective approaches in postoperative care. Materials/Methods A retrospective analysis was performed on all robotic-assisted radical prostatectomies (RARP) identified from a single institution between 29th June 2017 to 28th June 2019. This interval was chosen in an attempt to avoid bias or confounding variables associated with the SRS-CoV-2 pandemic. A single clinician conducted a comprehensive medical record review using unit record numbers corresponding to identified procedural codes. Demographics and variables were recorded, including postoperative test results, hospital length of stay and 30-day readmission rates. Patients were assigned to either 'Routine Postoperative tests' (RPOT) or 'No Routine Postoperative tests' (No RPOT) and a comparative analysis was performed. Using the Australian National Pharmaceutical Benefits Scheme (PBS) pricing guide, total expenditure was calculated. Results A total of 319 patients were included in the study with an average of 2.5 tests per patient within the first 24 hours. Routine postoperative tests had no bearing on outcomes, with comparable readmission rates between cohorts, and a significantly shorter length of stay in the "No routine postoperative tests" group when compared to the "Routine Postoperative Tests". A total of 1028 tests were performed within the first 48 hours following surgery with expenditure on routine testing totalling $20,516 based on the Australian PBS pricing schedule. Abnormal results were returned on 96% of patients. In the RPOT group, 18 out of the 20 common interventions occurred from 302 RARP. Among the patients in the RPOT group, eight individuals underwent blood transfusions. However, none of these patients met the hospital-specific criteria for transfusion, which require a hemoglobin level below 70 or symptomatic presentation with a hemoglobin level below 80. Conclusion The data suggests routine postoperative laboratory has no bearing on re-admission rates, with patients experiencing significantly shorter hospital stays. Furthermore, our results indicate inefficient use of routine postoperative laboratory, with few clinical interventions, frequent abnormal results, and significant accumulative expenses.

Optogenetic activation of visual thalamus generates artificial visual percepts. eLife 2023; 12:e90431.

Abstract
The lateral geniculate nucleus (LGN), a retinotopic relay center where visual inputs from the retina are processed and relayed to the visual cortex, has been proposed as a potential target for artificial vision. At present, it is unknown whether optogenetic LGN stimulation is sufficient to elicit behaviorally relevant percepts, and the properties of LGN neural responses relevant for artificial vision have not been thoroughly characterized. Here, we demonstrate that tree shrews pretrained on a visual detection task can detect optogenetic LGN activation using an AAV2-CamKIIα-ChR2 construct and readily generalize from visual to optogenetic detection. Simultaneous recordings of LGN spiking activity and primary visual cortex (V1) local field potentials (LFPs) during optogenetic LGN stimulation show that LGN neurons reliably follow optogenetic stimulation at frequencies up to 60 Hz and uncovered a striking phase locking between the V1 LFP and the evoked spiking activity in LGN. These phase relationships were maintained over a broad range of LGN stimulation frequencies, up to 80 Hz, with spike field coherence values favoring higher frequencies, indicating the ability to relay temporally precise information to V1 using light activation of the LGN. Finally, V1 LFP responses showed sensitivity values to LGN optogenetic activation that were similar to the animal's behavioral performance. Taken together, our findings confirm the LGN as a potential target for visual prosthetics in a highly visual mammal closely related to primates.

Abstract
We present measurements of the cross section and double-helicity asymmetry A_{LL} of direct-photon production in p[over →]+p[over →] collisions at sqrt[s]=510 GeV. The measurements have been performed at midrapidity (|η|<0.25) with the PHENIX detector at the Relativistic Heavy Ion Collider. At relativistic energies, direct photons are dominantly produced from the initial quark-gluon hard scattering and do not interact via the strong force at leading order. Therefore, at sqrt[s]=510 GeV, where leading-order-effects dominate, these measurements provide clean and direct access to the gluon helicity in the polarized proton in the gluon-momentum-fraction range 0.02<x<0.08, with direct sensitivity to the sign of the gluon contribution.

Abstract
OBJECTIVES To provide a comprehensive narrative review of the published data on the impact of hydrogel spacers on rectal dosimetry and toxicity and to outline the practicalities of inserting hydrogel spacers. RESULTS A growing body of evidence suggests that the administration of hydrogel spacers is safe and is associated with limited peri-operative morbidity. The impact on rectal dosimetry has been clearly established and use of hydrogel spacers is associated with reduced rectal morbidity. These results have been corroborated by several Phase II and III clinical trials and subsequent meta-analysis. There are several areas for future research, including the role of hydrogel spacers in prostate stereotactic beam radiotherapy and post-radiotherapy local recurrence. CONCLUSIONS Hydrogel spacers provide a low-morbidity method to potential reduce rectal toxicity after radiation therapy in men with prostate cancer. Data outlining sexual function and oncological outcomes are limited to date. Future studies, currently being conducted, may provide further clarification of the role of hydrogel spacers in prostate cancer management.

Abstract
Background The association between dietary intake of foods of animal origin and follicular lymphoma (FL) risk and survival is uncertain. In this study, we examined the relationship between dietary intake of dairy foods and fats, meat, fish and seafoods, and the likelihood of FL and survival. Methods We conducted a population-based family case-control study in Australia between 2011 and 2016 and included 710 cases, 303 siblings and 186 spouse/partner controls. We assessed dietary intake of animal products prior to diagnosis (the year before last) using a structured food frequency questionnaire and followed-up cases over a median of 6.9 years using record linkage to national death data. We examined associations with the likelihood of FL using logistic regression and used Cox regression to assess association with all-cause and FL-specific mortality among cases. Results We observed an increased likelihood of FL with increasing daily quantity of oily fish consumption in the year before last (highest category OR = 1.96, CI = 1.02-3.77; p-trend 0.06) among cases and sibling controls, but no associations with spouse/partner controls. We found no association between the likelihood of FL and the consumption of other types of fish or seafood, meats or dairy foods and fats. In FL cases, we found no association between meat or oily fish intake and all-cause or FL-specific mortality. Conclusion Our study showed suggestive evidence of a positive association between oily fish intake and the likelihood of FL, but findings varied by control type. Further investigation of the potential role of environmental contaminants in oily fish on FL etiology is warranted.

Abstract
ABSTRACTStructural competency is a recent framework for understanding and addressing the structural drivers of disease. Latin American Social Medicine and Collective Health is a decades-long movement similarly concerned with the study and transformation of social structures to achieve health equity. In this paper, we put insights from Latin American Social Medicine and Collective Health into conversation with the developing structural competency framework. We focus specifically on insights from Jaime Breilh's new article summarising his theoretical work on medical ethics and rights in this special issue and his new book, Critical Epidemiology and the People's Health. This paper is comprised of three parts. Part 1 provides an introduction to the structural competency framework. Part 2 provides an overview of the Latin American Social Medicine and Collective Health movement, along with a summary of the social determination of health paradigm. Part 3 places insights from these works into conversation with structural competency and considers ways in which Latin American Social Medicine and Collective Health might inform the further development of structural competency, and potentially vice versa. The paper closes by calling for greater attention to Latin American Social Medicine and Collective Health among those committed to health equity within the anglophone world.

Characterizing the metabolic effects of the selective inhibition of gut microbial β-glucuronidases in mice. Sci Rep 2022; 12:17435.

Abstract
The hydrolysis of xenobiotic glucuronides by gut bacterial glucuronidases reactivates previously detoxified compounds resulting in severe gut toxicity for the host. Selective bacterial β-glucuronidase inhibitors can mitigate this toxicity but their impact on wider host metabolic processes has not been studied. To investigate this the inhibitor 4-(8-(piperazin-1-yl)-1,2,3,4-tetrahydro-[1,2,3]triazino[4',5':4,5]thieno[2,3-c]isoquinolin-5-yl)morpholine (UNC10201652, Inh 9) was administered to mice to selectively inhibit a narrow range of bacterial β-glucuronidases in the gut. The metabolomic profiles of the intestinal contents, biofluids, and several tissues involved in the enterohepatic circulation were measured and compared to control animals. No biochemical perturbations were observed in the plasma, liver or gall bladder. In contrast, the metabolite profiles of urine, colon contents, feces and gut wall were altered compared to the controls. Changes were largely restricted to compounds derived from gut microbial metabolism. This work establishes that inhibitors targeted towards bacterial β-glucuronidases modulate the functionality of the intestinal microbiota without adversely impacting the host metabolic system.

Abstract
BACKGROUND The influence of early-life growth pattern and body size on follicular lymphoma (FL) risk and survival is unclear. In this study, we aimed to investigate the association between gestational age, growth during childhood, body size, changes in body shape over time, and FL risk and survival. METHODS We conducted a population-based family case-control study and included 706 cases and 490 controls. We ascertained gestational age, growth during childhood, body size and body shape using questionnaires and followed-up cases (median=83 months) using record linkage with national death records. We used a group-based trajectory modeling approach to identify body shape trajectories from ages 5-70. We examined associations with FL risk using unconditional logistic regression and used Cox regression to assess the association between body mass index (BMI) and all-cause and FL-specific mortality among cases. RESULTS We found no association between gestational age, childhood height and FL risk. We observed a modest increase in FL risk with being obese 5 years prior to enrolment (OR=1.43, 95 %CI=0.99-2.06; BMI ≥30 kg/m2) and per 5-kg/m2 increase in BMI 5 years prior to enrolment (OR=1.14, 95 %CI=0.99-1.31). The excess risk for obesity 5 years prior to enrolment was higher for ever-smokers (OR=2.00, 95 %CI=1.08-3.69) than never-smokers (OR=1.14, 95 %CI=0.71-1.84). We found no association between FL risk and BMI at enrolment, BMI for heaviest lifetime weight, the highest categories of adult weight or height, trouser size, body shape at different ages or body shape trajectory. We also observed no association between all-cause or FL-specific mortality and excess adiposity at or prior to enrolment. CONCLUSION We observed a weak association between elevated BMI and FL risk, and no association with all-cause or FL-specific mortality, consistent with previous studies. Future studies incorporating biomarkers are needed to elucidate possible mechanisms underlying the role of body composition in FL etiology.

Abstract
The concept of the social determinants of health has become increasingly accepted and mainstream in anglophone public health over the past three decades. Moreover, it has been widely adopted into diverse geographic, sociocultural, and linguistic contexts. By recognizing the role of social conditions in influencing health inequalities, the concept challenges narrow behavioral and reductive biological understandings of health. Despite this, scholars and activists have critiqued the concept of the social determinants of health for being incomplete and even misrepresenting the true nature of health inequities. Arguably, these critiques have been most thoroughly developed among those working in the Latin American social medicine and collective health traditions who formulated the "social determination of health" paradigm and the concept of interculturality decades prior to the advent of the social determinants of health. We draw on Jaime Breilh's main works, with a focus on the recently published book, Critical Epidemiology and the People's Health, to (1) provide a broad overview of the social determination of health paradigm and its approach to interculturality and (2) clarify how these ideas and the broader collective health movement challenge assumptions within the social determinants of health concept.

Clinical characteristics with inflammation profiling of long COVID and association with 1-year recovery following hospitalisation in the UK: a prospective observational study. THE LANCET. RESPIRATORY MEDICINE 2022; 10:761-775.

Abstract
BACKGROUND No effective pharmacological or non-pharmacological interventions exist for patients with long COVID. We aimed to describe recovery 1 year after hospital discharge for COVID-19, identify factors associated with patient-perceived recovery, and identify potential therapeutic targets by describing the underlying inflammatory profiles of the previously described recovery clusters at 5 months after hospital discharge. METHODS The Post-hospitalisation COVID-19 study (PHOSP-COVID) is a prospective, longitudinal cohort study recruiting adults (aged ≥18 years) discharged from hospital with COVID-19 across the UK. Recovery was assessed using patient-reported outcome measures, physical performance, and organ function at 5 months and 1 year after hospital discharge, and stratified by both patient-perceived recovery and recovery cluster. Hierarchical logistic regression modelling was performed for patient-perceived recovery at 1 year. Cluster analysis was done using the clustering large applications k-medoids approach using clinical outcomes at 5 months. Inflammatory protein profiling was analysed from plasma at the 5-month visit. This study is registered on the ISRCTN Registry, ISRCTN10980107, and recruitment is ongoing. FINDINGS 2320 participants discharged from hospital between March 7, 2020, and April 18, 2021, were assessed at 5 months after discharge and 807 (32·7%) participants completed both the 5-month and 1-year visits. 279 (35·6%) of these 807 patients were women and 505 (64·4%) were men, with a mean age of 58·7 (SD 12·5) years, and 224 (27·8%) had received invasive mechanical ventilation (WHO class 7-9). The proportion of patients reporting full recovery was unchanged between 5 months (501 [25·5%] of 1965) and 1 year (232 [28·9%] of 804). Factors associated with being less likely to report full recovery at 1 year were female sex (odds ratio 0·68 [95% CI 0·46-0·99]), obesity (0·50 [0·34-0·74]) and invasive mechanical ventilation (0·42 [0·23-0·76]). Cluster analysis (n=1636) corroborated the previously reported four clusters: very severe, severe, moderate with cognitive impairment, and mild, relating to the severity of physical health, mental health, and cognitive impairment at 5 months. We found increased inflammatory mediators of tissue damage and repair in both the very severe and the moderate with cognitive impairment clusters compared with the mild cluster, including IL-6 concentration, which was increased in both comparisons (n=626 participants). We found a substantial deficit in median EQ-5D-5L utility index from before COVID-19 (retrospective assessment; 0·88 [IQR 0·74-1·00]), at 5 months (0·74 [0·64-0·88]) to 1 year (0·75 [0·62-0·88]), with minimal improvements across all outcome measures at 1 year after discharge in the whole cohort and within each of the four clusters. INTERPRETATION The sequelae of a hospital admission with COVID-19 were substantial 1 year after discharge across a range of health domains, with the minority in our cohort feeling fully recovered. Patient-perceived health-related quality of life was reduced at 1 year compared with before hospital admission. Systematic inflammation and obesity are potential treatable traits that warrant further investigation in clinical trials.

Associations between Smoking and Alcohol and Follicular Lymphoma Incidence and Survival: A Family-Based Case-Control Study in Australia. Cancers (Basel) 2022; 14:cancers14112710. [PMID: 35681690 PMCID: PMC9179256 DOI: 10.3390/cancers14112710] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2022] [Revised: 05/16/2022] [Accepted: 05/27/2022] [Indexed: 12/10/2022] Open
Abstract
The association between smoking and alcohol consumption and follicular lymphoma (FL) incidence and clinical outcome is uncertain. We conducted a population-based family case-control study (709 cases: 490 controls) in Australia. We assessed lifetime history of smoking and recent alcohol consumption and followed-up cases (median = 83 months). We examined associations with FL risk using unconditional logistic regression and with all-cause and FL-specific mortality of cases using Cox regression. FL risk was associated with ever smoking (OR = 1.38, 95%CI = 1.08−1.74), former smoking (OR = 1.36, 95%CI = 1.05−1.77), smoking initiation before age 17 (OR = 1.47, 95%CI = 1.06−2.05), the highest categories of cigarettes smoked per day (OR = 1.44, 95%CI = 1.04−2.01), smoking duration (OR = 1.53, 95%CI = 1.07−2.18) and pack-years (OR = 1.56, 95%CI = 1.10−2.22). For never smokers, FL risk increased for those exposed indoors to >2 smokers during childhood (OR = 1.84, 95%CI = 1.11−3.04). For cases, current smoking and the highest categories of smoking duration and lifetime cigarette exposure were associated with elevated all-cause mortality. The hazard ratio for current smoking and FL-specific mortality was 2.97 (95%CI = 0.91−9.72). We found no association between recent alcohol consumption and FL risk, all-cause or FL-specific mortality. Our study showed consistent evidence of an association between smoking and increased FL risk and possibly also FL-specific mortality. Strengthening anti-smoking policies and interventions may reduce the population burden of FL.

Abstract
Priapism is an urgent urological condition with varied aetiology that may be classified as low flow (ischaemic) or high flow (non-ischaemic). Diagnosis requires detailed clinical history and examination combined with appropriate investigations such as cavernosal blood gas sampling and penile Doppler ultrasound. In the case of high-flow priapism CT angiography can identify sources of abnormal arterial blood flow and cases may be managed conservatively, with surgery or through arterial embolisation. We detail a case of a young man presented 2 weeks after perineal trauma with high-flow priapism with an equivocal penile Doppler ultrasound. Cavernosal blood gas sampling was consistent with arterial blood and CT angiography was performed showing an arteriovenous fistula. The patient was then successfully managed with arterial embolisation resulting in detumescence and preserving sexual function.

Abstract
Abstract
Background
Symptomatic giant para-oesophageal hernia (PEH) can often be troublesome and may require surgical intervention. It commonly presents with dyspnoea, post-prandial pain, vomiting and dysphagia but rarely strangulation. In a good proportion of patients, iron deficiency anaemia may also be present. Patients are often elderly and may have co-morbidities and hence there may be a reluctance to refer and to offer surgery. This long-term study offers an insight to the outcomes following this complex surgery in a relatively elderly cohort of patients.
Methods
A retrospective analysis of prospectively collected data of patients who underwent surgery for symptomatic PEH from January 2001- June 2021 was performed. Clinical presentation, management, post-operative clinical outcomes, radiographic evaluation, pre and post-operative haemoglobin levels, respiratory function {Forced Vital Capacity (FVC), Forced Expiratory Volume in 1 Second (FEV1)} as well as quality-of-life (QoL) with SF-36 questioners (including general health, physical, emotional and social components) were assessed.
Results
202 patients (122-females) with median age 68 years (36-88) underwent PEH-surgery. The commonest symptomEighty-one presented with dyspnoea(41%). Ninety-five(47%) were ASA III, 119(59%) had microcytic-anaemia. 142(70%) had a fundoplication during PEHR. Hospital-stay was significantly lower in laparoscopic group
Mortality:1.8%(2/112).
Median follow-up:10 years. Symptoms improved in 166(82%) with respiratory function and anaemia. 42(21%) had radiological recurrences but only nine (4.5%) clinical recurrence requiring surgery.
Conclusions
Laparoscopic repair of giant para-oesophageal hernia is safe with good outcomes in all age groups with improvement in symptoms, quality of life, respiratory function and associated anaemia.

Abstract
Intravesical Bacillus Calmette-Guérin vaccine, one of the most successful bio-therapies to date, has been the gold standard treatment for non-muscle invasive bladder cancer for 44 years. International shortages have necessitated rationing this life-saving medication with deleterious effects on the primary treatment of high-grade non-muscle invasive bladder cancer. Understanding the history of intravesical Bacillus Calmette-Guérin gives us insight into the current shortages and future perspectives for novel immunotherapy opportunities against this deadly disease.

Abstract
Studying spin-momentum correlations in hadronic collisions offers a glimpse into a three-dimensional picture of proton structure. The transverse single-spin asymmetry for midrapidity isolated direct photons in p^{↑}+p collisions at sqrt[s]=200 GeV is measured with the PHENIX detector at the Relativistic Heavy Ion Collider (RHIC). Because direct photons in particular are produced from the hard scattering and do not interact via the strong force, this measurement is a clean probe of initial-state spin-momentum correlations inside the proton and is in particular sensitive to gluon interference effects within the proton. This is the first time direct photons have been used as a probe of spin-momentum correlations at RHIC. The uncertainties on the results are a 50-fold improvement with respect to those of the one prior measurement for the same observable, from the Fermilab E704 experiment. These results constrain gluon spin-momentum correlations in transversely polarized protons.

Reliability of Addenbrooke's Cognitive Examination III in differentiating between dementia, mild cognitive impairment and older adults who have not reported cognitive problems.

Abstract
Diagnosing dementia can be challenging for clinicians, given the array of factors that contribute to changes in cognitive function. The Addenbrooke’s Cognitive Examination III (ACE-III) is commonly used in dementia assessments, covering the domains of attention, memory, fluency, visuospatial and language. This study aims to (1) assess the reliability of ACE-III to differentiate between dementia, mild cognitive impairment (MCI) and controls and (2) establish whether the ACE-III is useful for diagnosing dementia subtypes. Client records from the Northern Health and Social Care Trust (NHSCT) Memory Service (n = 2,331, 2013–2019) were used in the analysis including people diagnosed with Alzheimer’s disease (n = 637), vascular dementia (n = 252), mixed dementia (n = 490), MCI (n = 920) and controls (n = 32). There were significant differences in total ACE-III and subdomain scores between people with dementia, MCI and controls (p < 0.05 for all), with little overlap between distribution of total ACE-III scores (< 39%) between groups. The distribution of total ACE-III and subdomain scores across all dementias were similar. There were significant differences in scores for attention, memory and fluency between Alzheimer’s disease and mixed dementia, and for visuospatial and language between Alzheimer’s disease–vascular dementia (p < 0.05 for all). However, despite the significant differences across these subdomains, there was a high degree of overlap between these scores (> 73%) and thus the differences are not clinically relevant. The results suggest that ACE-III is a useful tool for discriminating between dementia, MCI and controls, but it is not reliable for discriminating between dementia subtypes. Nonetheless, the ACE-III is still a reliable tool for clinicians that can assist in making a dementia diagnosis in combination with other factors at assessment.

Abstract
Understanding human sleep requires appropriate animal models. Sleep has been extensively studied in rodents, although rodent sleep differs substantially from human sleep. Here we investigate sleep in tree shrews, small diurnal mammals phylogenetically close to primates, and compare it to sleep in rats and humans using electrophysiological recordings from frontal cortex of each species. Tree shrews exhibited consolidated sleep, with a sleep bout duration parameter, τ, uncharacteristically high for a small mammal, and differing substantially from the sleep of rodents that is often punctuated by wakefulness. Two NREM sleep stages were observed in tree shrews: NREM, characterized by high delta waves and spindles, and an intermediate stage (IS-NREM) occurring on NREM to REM transitions and consisting of intermediate delta waves with concomitant theta-alpha activity. While IS-NREM activity was reliable in tree shrews, we could also detect it in human EEG data, on a subset of transitions. Finally, coupling events between sleep spindles and slow waves clustered near the beginning of the sleep period in tree shrews, paralleling humans, whereas they were more evenly distributed in rats. Our results suggest considerable homology of sleep structure between humans and tree shrews despite the large difference in body mass between these species. Dimanico et al investigated sleep in tree shrews using electrophysiological recordings and compared it to equivalent read-outs in rats and humans. They reported that there was considerable homology of sleep structure between humans and tree shrews despite the difference in body mass between these species.

Abstract
BACKGROUND Haemorrhagic and thrombotic complications are common in dialysis patients on warfarin; thus, accurate international normalized ratio (INR) monitoring is critical. For expediency and patient comfort, blood sampling from the haemodialysis access or circuit is commonly performed. Point-of-care (POC) INR machines allow both peripheral vein preservation and rapid results, yet are not validated in the haemodialysis population. METHODS A prospective cohort study in haemodialysis patients taking warfarin was undertaken. Three paired samples were drawn over a single session: peripheral blood INR, POC INR, and dialysis INR. Agreement using Bland-Altman analysis and correlation coefficients between the peripheral blood INR, haemodialysis INR, and POC INR were calculated. Inappropriate dosing decisions based on haemodialysis or POC INR were quantified. RESULTS Amongst 34 patients, agreement between the dialysis INR and peripheral blood INR was high, with the haemodialysis INR differing from the peripheral INR by <±0.2, 85.2% of the time. Correlation between the 2 methods was high (r = 0.914; p < 0.001). POC INR differed from peripheral INR values by <±0.2, 67.6% of the time, with less agreement at higher INR values. Dosing decisions were incongruent between the dialysis and peripheral INR in 6%, whilst the POC and peripheral INR disagreed in 26%. CONCLUSIONS There was good agreement and correlation between the peripheral blood, haemodialysis access/circuit, and POC INR values. POC INR was less reliable at higher values, and dosing decisions differed from the peripheral INR in a quarter of cases.

Abstract
The "political economy of health" is concerned with how political and economic domains interact and shape individual and population health outcomes. However, the term is variously defined in the public health, medical, and social science literatures.This could result in confusion about the term and its associated tradition, thereby constituting a barrier to its application in public health research and practice.To address these issues, I survey the political economy of health tradition, clarify its specifically Marxian theoretical legacy, and discuss its relevance to understanding and addressing public health issues. I conclude by discussing the benefits of employing critical theories of race and racism with Marxian political economy to better understand the roles of class exploitation and racial oppression in epidemiological patterning.

Abstract
Structural competency is a new curricular framework for training health professionals to recognise and respond to disease and its unequal distribution as the outcome of social structures, such as economic and legal systems, healthcare and taxation policies, and international institutions. While extensive global health research has linked social structures to the disproportionate burden of disease in the Global South, formal attempts to incorporate the structural competency framework into US-based global health education have not been described in the literature. This paper fills this gap by articulating five sub-competencies for structurally competent global health instruction. Authors drew on their experiences developing global health and structural competency curricula-and consulted relevant structural competency, global health, social science, social theory, and social determinants of health literatures. The five sub-competencies include: (1) Describe the role of social structures in producing and maintaining health inequities globally, (2) Identify the ways that structural inequalities are naturalised within the field of global health, (3) Discuss the impact of structures on the practice of global health, (4) Recognise structural interventions for addressing global health inequities, and (5) Apply the concept of structural humility in the context of global health.

Abstract
7530 Background: About 40-50% of older patients (pts) with AML attain complete remission (CR) with induction chemotherapy (IC) but relapse is common.Effective, well-tolerated maintenance treatment (Tx) is needed for older pts in remission who are not eligible for hematopoietic stem cell transplant (HSCT). CC-486 is an oral hypomethylating agent that allows for extended dosing schedules ( >7 days [d]/cycle) to sustain therapeutic activity. In the phase III placebo (PBO)-controlled QUAZAR AML-001 trial (NCT01757535), CC-486 maintenance therapy in pts with AML in first remission following IC produced significant improvements in overall and relapse-free survival. Here we report safety and tolerability findings among pt subgroups defined by age at study entry. Methods: Eligible pts were ≥ 55 yrs of age, with de novo or secondary AML, intermediate or poor risk cytogenetics, and ECOG PS ≤ 3; had achieved first CR or CRi after IC ± consolidation; and were not candidates for HSCT. Within 4 mo of CR/CRi, pts were randomized 1:1 to CC-486 300 mg or PBO QD on d 1–14 of repeated 28d Tx cycles. Safety was assessed across 3 age subgroups (≥ 55 to < 65, ≥ 65 to < 75, and ≥ 75 yrs) in pts who received ≥ 1 dose of study drug. Adverse events (AEs) were coded using MedDRA v. 22.0 and graded by NCI-CTCAE v. 4.0. Results: 469 pts ( >99% of all enrolled pts) were evaluable for safety (CC-486 n = 236; PBO n = 233). Median age was 68 yrs (range 55-86). Age distribution was similar between the two Tx arms (Table). Between Tx arms, AE rates within each age stratum were similar to rates in the overall study population. The most common AEs (any grade) with CC-486 were GI events, which were more frequent than in the PBO arm across age groups. Within the CC-486 arm, AE rates were generally consistent across age groups, except for constipation, which was > 20% more frequent in pts aged ≥ 75 yrs, and thrombocytopenia, which was ≥ 20% less frequent in this group (Table). Overall, 13% and 4% of pts in the CC-486 and PBO groups discontinued Tx due to AEs. Conclusions: In QUAZAR AML-001, CC-486 was generally well tolerated in all age groups, including elderly pts aged ≥ 75 yrs. Clinical trial information: NCT01757535 . [Table: see text]

Abstract
Cooling of beams of gold ions using electron bunches accelerated with radio-frequency systems was recently experimentally demonstrated in the Relativistic Heavy Ion Collider at Brookhaven National Laboratory. Such an approach is new and opens the possibility of using this technique at higher energies than possible with electrostatic acceleration of electron beams. The challenges of this approach include generation of electron beams suitable for cooling, delivery of electron bunches of the required quality to the cooling sections without degradation of beam angular divergence and energy spread, achieving the required small angles between electron and ion trajectories in the cooling sections, precise velocity matching between the two beams, high-current operation of the electron accelerator, as well as several physics effects related to bunched-beam cooling. Here we report on the first demonstration of cooling hadron beams using this new approach.

We sought to determine incidence, etiologies, and yield of genetic testing in infantile onset developmental and epileptic encephalopathies (DEEs) in a population isolate, with an intensive multistage approach. Infants born in Tasmania between 2011 and 2016, with seizure onset <2 years of age, epileptiform EEG, frequent seizures, and developmental impairment, were included. Following review of EEG databases, medical records, brain MRIs, and other investigations, clinical genetic testing was undertaken with subsequent research interrogation of whole exome sequencing (WES) in unsolved cases. The incidence of infantile DEEs was 0.44/1000 per year (95% confidence interval 0.25 to 0.71), with 16 cases ascertained. The etiology was structural in 5/16 cases. A genetic basis was identified in 6 of the remaining 11 cases (3 gene panel, 3 WES). In two further cases, WES identified novel variants with strong in silico data; however, paternal DNA was not available to support pathogenicity. The etiology was not determined in 3/16 (19%) cases, with a candidate gene identified in one of these. Pursuing clinical imaging and genetic testing followed by WES at an intensive research level can give a high diagnostic yield in the infantile DEEs, providing a solid base for prognostic and genetic counseling.

Abstract
The PHENIX collaboration presents first measurements of low-momentum (0.4<p_{T}<3 GeV/c) direct-photon yields from Au+Au collisions at sqrt[s_{NN}]=39 and 62.4 GeV. For both beam energies the direct-photon yields are substantially enhanced with respect to expectations from prompt processes, similar to the yields observed in Au+Au collisions at sqrt[s_{NN}]=200. Analyzing the photon yield as a function of the experimental observable dN_{ch}/dη reveals that the low-momentum (>1 GeV/c) direct-photon yield dN_{γ}^{dir}/dη is a smooth function of dN_{ch}/dη and can be well described as proportional to (dN_{ch}/dη)^{α} with α≈1.25. This scaling behavior holds for a wide range of beam energies at the Relativistic Heavy Ion Collider and the Large Hadron Collider, for centrality selected samples, as well as for different A+A collision systems. At a given beam energy, the scaling also holds for high p_{T} (>5 GeV/c), but when results from different collision energies are compared, an additional sqrt[s_{NN}]-dependent multiplicative factor is needed to describe the integrated-direct-photon yield.

Opioid overdose education and naloxone distribution: Development of the Veterans Health Administration's national program. J Am Pharm Assoc (2003) 2017; 57:S168-S179.e4.

Abstract
OBJECTIVES To prevent opioid-related mortality, the Veterans Health Administration (VHA) developed a national Opioid Overdose Education and Naloxone Distribution (OEND) program. SETTING VHA's OEND program sought national implementation of OEND across all medical facilities (n = 142). PRACTICE DESCRIPTION This paper describes VHA's efforts to facilitate nationwide health care system-based OEND implementation, including the critical roles of VHA's national pharmacy services and academic detailing services. PRACTICE INNOVATION VHA is the first large health care system in the United States to implement OEND nationwide. Launching the national program required VHA to translate a primarily community-based public health approach to OEND into a health care system-based approach that distributed naloxone to patients with opioid use disorders as well as to patients prescribed opioid analgesics. Key innovations included developing steps to implement OEND, pharmacy developing standard naloxone rescue kits, adding those kits to the VHA National Formulary, centralizing kit distribution, developing clinical guidance for issuing naloxone kits, and supporting OEND as a focal campaign of academic detailing. Other innovations included the development of patient and provider education resources (e.g., brochures, videos, accredited training) and implementation and evaluation resources (e.g., technical assistance, clinical decision support tools). EVALUATION Clinical decision support tools that leverage VHA national data are available to clinical staff with appropriate permissions. These tools allow staff and leaders to evaluate OEND implementation and provide actionable next steps to help them identify patients who could benefit from OEND. RESULTS Through fiscal year 2016, VHA dispensed 45,178 naloxone prescriptions written by 5693 prescribers to 39,328 patients who were primarily prescribed opioids or had opioid use disorder. As of February 2, 2016, there were 172 spontaneously reported opioid overdose reversals with the use of VHA naloxone prescriptions. CONCLUSION VHA has successfully translated community-based OEND into health care system-based OEND targeting 2 patient populations. There is a tremendous amount that can be learned from VHA's experience implementing this novel health care innovation nationwide.

Abstract
OBJECTIVES To describe an outbreak of Salmonella enteritidis phage type (PT) 14b in people who had eaten at a restaurant, and the investigation and subsequent prosecution of the food business operator (FBO). STUDY DESIGN The local health protection team and environmental health department formed an outbreak control team to investigate the outbreak. METHODS Epidemiological, microbiological, and environmental investigations were undertaken. Epidemiological investigations involved case finding and interviews. Microbiological investigation: stool samples from the suspected cases and environmental samples from the implicated food business were investigated. Salmonella isolates obtained were subjected to multiple locus variable-number tandem repeat analysis (MLVA) profiling and whole genome sequencing. In addition, adenosine triphosphate (ATP) hygiene swab tests were used to verify the quality of cleaning procedures and data loggers were used to determine the water temperature of the mechanical dishwasher. RESULTS Fifteen cases of illness where the causative agent was shown to be S. enteritidis PT14b were identified, all of whom had eaten at the same restaurant. S. enteritidis PT14b was also identified from three of the 11 food and environmental samples taken at the restaurant and found to have the same MLVA profile as the cases. A case for prosecution was built and the FBO was successfully prosecuted in July 2015. CONCLUSIONS This investigation highlighted that the use of molecular typing as part of thorough epidemiological, microbiological, and environmental investigations can present a robust case for prosecution against restaurants which pose a risk to public health.

Mentoring Female Global Managers: A Social Comparison Perspective. SOUTH ASIAN JOURNAL OF HUMAN RESOURCES MANAGEMENT 2017.

Abstract
The global business environment is new, complex and not well understood by many of the managers having to “learn by doing.” This “on-the-run” learning experience is particularly difficult for female global managers in the South Asian region who may not have the input or support of others as to how to prepare for relocating overseas. The lack of assistance is further exacerbated by the growing importance of large emerging markets. Given limited history with these key emerging markets, some means of accelerating learning and transferring knowledge to the next generation of (global) managers is a necessity. This article examines one means of addressing the need to learn from others more experienced in global business through mentoring. Social comparison theory is used as the theoretical lens by which to examine the mentoring process for global female managers, a type of managerial talent particularly void of organizational structural support. A means for developing a mentoring programme for global female managers is also developed.

Prevalence, Disparities, And Determinants Of Primary Cesarean Births Among First-Time Mothers In Mexico. Health Aff (Millwood) 2017; 36:714-722.

Abstract
Mexico has the second-highest prevalence of cesarean deliveries in the Americas, behind Brazil. Having had a previous cesarean delivery is highly predictive of having subsequent cesarean deliveries, yet evidence on the drivers of primary (that is, first-time) cesarean deliveries is sparse. Using 2014 Mexican birth certificate data and performing population-level analyses of data on 600,124 first-time mothers giving birth after at least thirty-seven weeks of gestation, we examined the prevalence and determinants of primary cesarean deliveries. We found a very high prevalence of cesarean deliveries among these women-48.7 percent-and wide variations across insurance coverage types. Enrollees in Seguro Popular, the public health insurance program introduced in 2003 for the previously uninsured and gradually rolled out nationally, had a cesarean rate of 40 percent, while women insured through the Social Security Institute for Civil Servants had a rate of 78 percent. The lower risk of primary cesarean deliveries among Seguro Popular enrollees persisted after adjustment for covariates. Rates of primary cesarean deliveries were particularly high in private birthing facilities for all first-time mothers. Reducing the rate of cesarean deliveries in Mexico will require interventions across types of insurance and birthing facilities and will also require targeted public health messaging.
