John Banville
\"This critical study of John Banville's major work considers the manner in which his fiction intersects with a variety of ideas relating to art. It also proposes that Banville's fiction represents a significant development in Irish writing, and contemporary prose fiction, in its advanced reconstitution of the self-reflexive form\"-- Provided by publisher.

Alcohol and Cancer: Epidemiology and Biological Mechanisms
Approximately 4% of cancers worldwide are caused by alcohol consumption. Drinking alcohol increases the risk of several cancer types, including cancers of the upper aerodigestive tract, liver, colorectum, and breast. In this review, we summarise the epidemiological evidence on alcohol and cancer risk and the mechanistic evidence of alcohol-mediated carcinogenesis. There are several mechanistic pathways by which the consumption of alcohol, as ethanol, is known to cause cancer, though some are still not fully understood. Ethanol’s metabolite acetaldehyde can cause DNA damage and block DNA synthesis and repair, whilst both ethanol and acetaldehyde can disrupt DNA methylation. Ethanol can also induce inflammation and oxidative stress leading to lipid peroxidation and further DNA damage. One-carbon metabolism and folate levels are also impaired by ethanol. Other known mechanisms are discussed. Further understanding of the carcinogenic properties of alcohol and its metabolites will inform future research, but there is already a need for comprehensive alcohol control and cancer prevention strategies to reduce the burden of cancer attributable to alcohol.

Global burden of colorectal cancer in 2020 and 2040: incidence and mortality estimates from GLOBOCAN
ObjectiveColorectal cancer (CRC) is the third most common cancer worldwide. The geographical and temporal burden of this cancer provides insights into risk factor prevalence and progress in cancer control strategies. We examine the current and future burden of CRC in 185 countries in 2020 and 2040.MethodsData on CRC cases and deaths were extracted from the GLOBOCAN database for the year 2020. Age-standardised incidence and mortality rates were calculated by sex, country, world region and Human Development Index (HDI) for 185 countries. Age-specific rates were also estimated. The predicted number of cases and deaths in 2040 were calculated based on global demographic projections by HDI.ResultsOver 1.9 million new CRC cases and 930 000 deaths were estimated in 2020. Incidence rates were highest in Australia/ New Zealand and European regions (40.6 per 100 000, males) and lowest in several African regions and Southern Asia (4.4 per 100 000, females). Similar patterns were observed for mortality rates, with the highest observed in Eastern Europe (20.2 per 100 000, males) and the lowest in Southern Asia (2.5 per 100 000, females). The burden of CRC is projected to increase to 3.2 million new cases and 1.6 million deaths by 2040 with most cases predicted to occur in high or very high HDI countries.ConclusionsCRC is a highly frequent cancer worldwide, and largely preventable through changes in modifiable risk factors, alongside the detection and removal of precancerous lesions. With increasing rates in transitioning countries and younger adults, there is a pressing need to better understand and act on findings to avert future cases and deaths from the disease.

Fighting with shadows or, Sciamachy : a novel
\"Fighting with Shadows tells of violently sundered geographical borders, of maddening religious differences, of the anguished gaps between people as they struggle to find each other, and of how the dead reside among its inhabitants long after they've passed. The imagination's encounter with reality registers Dermot Healey's relentless fascination with the way things are seen and with the things themselves, or the \"erotica of little things.\" A realist account and nightmarish fable, Fighting with Shadows is critical to the history of modern Irish fiction\"-- Provided by publisher.

Adiposity and gastrointestinal cancers: epidemiology, mechanisms and future directions
Excess adiposity is a risk factor for several cancers of the gastrointestinal system, specifically oesophageal adenocarcinoma and colorectal, small intestine, pancreatic, liver, gallbladder and stomach cancers. With the increasing prevalence of obesity in nearly all regions of the world, this relationship could represent a growing source of cancers of the digestive system. Experimental and molecular epidemiological studies indicate important roles for alterations in insulin signalling, adipose tissue-derived inflammation and sex hormone pathways in mediating the association between adiposity and gastrointestinal cancer. The intestinal microbiome, gut hormones and non alcoholic fatty liver disease (NAFLD) also have possible roles. However, important gaps remain in our knowledge. For instance, our understanding of how adiposity throughout the life course is related to the risk of gastrointestinal cancer development and of how obesity influences gastrointestinal cancer prognosis and survival is limited. Nonetheless, the increasing use of state-of-the-art analytical methods (such as omics technologies, Mendelian randomization and MRI) in large-scale epidemiological studies offers exciting opportunities to advance our understanding of the complex relationship between adiposity and gastrointestinal cancers. Here, we examine the epidemiology of associations between obesity and gastrointestinal cancer, explore potential mechanisms underlying these relationships and highlight important unanswered research questions.

The collected short stories
\"Dermot Healy wrote intricate and innovative short stories that, along with works by Neil Jordan and Desmond Hogan, relaunched the Irish short story tradition. Set in small-town Ireland and the equally suffocating confines of the Irish expat communities of 1970s London, Healy's stories show compassion toward the marginalized and the dispossessed. Gathering all of Healy's stories together for the first time, this collection includes the long prose-drama \"Before the Off\" and Healy's final short works, \"Along the Lines\" and \"Images\" -- Provided by publisher.

MeV proton acceleration at kHz repetition rate from ultra-intense laser liquid interaction
Laser acceleration of ions to MeV energies has been achieved on a variety of Petawatt laser systems, raising the prospect of ion beam applications using compact ultra-intense laser technology. However, translation from proof-of-concept laser experiment into real-world application requires MeV-scale ion energies and an appreciable repetition rate (>Hz). We demonstrate, for the first time, proton acceleration up to 2 MeV energies at a kHz repetition rate using a milli-joule-class short-pulse laser system. In these experiments, 5 mJ of ultrashort-pulse laser energy is delivered at an intensity near 5 × 10 18 W cm − 2 onto a thin-sheet, liquid-density target. Key to this effort is a flowing liquid ethylene glycol target formed in vacuum with thicknesses down to 400 nm and full recovery at 70 s, suggesting its potential use at >kHz rate. Novel detectors and experimental methods tailored to high-repetition-rate ion acceleration by lasers were essential to this study and are described. In addition, particle-in-cell simulations of the laser-plasma interaction show good agreement with experimental observations.

Cesarean Delivery: Counseling Issues and Complication Management
Nearly one-third of all deliveries in the United States are cesarean deliveries. Compared with spontaneous vaginal delivery, cesarean delivery is associated with increased maternal and neonatal morbidity and mortality. Interventions that decrease the chance of a cesarean delivery include avoiding non–medically indicated induction of labor, avoiding amniotomy, and having a doula present. In North America, the most common reasons for cesarean delivery include elective repeat cesarean delivery, dystocia or failure to progress, malpresentation, and fetal heart rate tracings that suggest fetal distress. Post–cesarean delivery complications include pain, endomyometritis, wound separation/infection, urinary tract infection, gastrointestinal problems, deep venous thrombosis, and septic thrombophlebitis. Women with no risk factors for deep venous thrombosis other than the postpartum state and the operative delivery do not require thromboembolism prophylaxis other than early ambulation. A pregnant woman's decision to attempt a trial of labor after cesarean delivery or have a planned repeat cesarean delivery involves a balancing of maternal and neonatal risks, as well as personal preference after counseling by her physician. Approximately 75% of attempted trials of labor after cesarean delivery are successful. Provision of advanced maternity care practices by family physicians, including serving as primary surgeons for cesarean deliveries, is consistent with the goals of the patient-centered medical home.

Trauma in Pregnancy: Assessment, Management, and Prevention
Trauma complicates one in 12 pregnancies, and is the leading nonobstetric cause of death among pregnant women. The most common traumatic injuries are motor vehicle crashes, assaults, falls, and intimate partner violence. Nine out of 10 traumatic injuries during pregnancy are classified as minor, yet 60% to 70% of fetal losses after trauma are a result of minor injuries. In minor trauma, four to 24 hours of tocodynamometric monitoring is recommended. Ultrasonography has low sensitivity, but high specificity, for placental abruption. The Kleihauer-Betke test should be performed after major trauma to determine the degree of fetomaternal hemorrhage, regardless of Rh status. To improve the effectiveness of cardiopulmonary resuscitation, clinicians should perform left lateral uterine displacement by tilting the whole maternal body 25 to 30 degrees. Unique aspects of advanced cardiac life support include early intubation, removal of all uterine and fetal monitors, and performance of perimortem cesarean delivery. Proper seat belt use reduces the risk of maternal and fetal injuries in motor vehicle crashes. The lap belt should be placed as low as possible under the protuberant portion of the abdomen and the shoulder belt positioned off to the side of the uterus, between the breasts and over the midportion of the clavicle. All women of childbearing age should be routinely screened for intimate partner violence.
