Effects of Extruded Corn or Grain Sorghum on Intake, Digestibility, Weight Gain, and Carcasses of Finishing Steers

We conducted two trials to evaluate the effects of extruding vs dry-rolling either corn or grain sorghum on intake, digestibility, and performance of finishing steers. In Trial 1, 92 crossbred steers (average BW 413 kg) were used in a 2 x 2 factorial design. Diets contained either dry-rolled corn (RC), extruded corn (EC), dry-rolled grain sorghum (RGS), or extruded grain sorghum (EGS). Diets were fed for 110 d and contained 78.6% of the respective grain, 9% alfalfa pellets, 8.2% molasses, and 4.2% protein-mineral supplement. Daily gain was highest (P \u3c .049) for steers fed RC, and the ADG of steers fed RGS was higher than that of steers fed extruded diets; there was no difference in ADG between steers fed EC and those fed EGS. Steers fed dry-rolled diets consumed more DM (P = .001) than steers fed extruded diets. Feed efficiency was not affected (P = .18) by processing method, but steers fed corn utilized the diets more efficiently (P = .006) than steers fed grain sorghum. Except for carcass weight, carcass data were not affected by grain type (P \u3e .20). Dressing percentage, quality grade, and longissimus muscle area were lower (P \u3c .09) in steers that received extruded grain than in those that received dry-rolled grain. In Trial 2, five ruminally cannulated crossbred steers (average BW 518 kg) were used in a 4 x 4 + 1 Latin square design to evaluate the ruminal and total tract digestion characteristics of the diets used in Trial 1. Type of grain had no effect (P \u3e .16) on intake, total tract digestibility, or ruminal pH. Extruding corn or grain sorghum decreased intake (P \u3c .001) but increased (P \u3c .074) DM and starch digestibility compared with dry rolling; steers fed extruded diets had lower (P \u3c .032) ADF and NDF digestibilities. Ruminal in situ DM and starch disappearance were higher ( P \u3c .03) and ruminal pH was lower (P \u3c .052) in steers fed extruded grains than in those fed dry-rolled grains. Data from this study indicate that extruded corn and extruded grain sorghum are highly degradable feeds; however, decreased DM intake and lower ruminal pH levels resulted in lower performance

Modernisation and the practices of contemporary food shopping

This paper examines the relationship between modernisation, consumption, and society, challenging received ideas about the distinction between ‘modern’ and ‘premodern’ geographies of food consumption. While conventional accounts posit a historical progression from premodern to modern forms of consumption, associated with the rise of the supermarket and the demise of the corner store, we argue that such distinctions may, in fact, refer less to a historical process of transition than to a contrast between different forms of contemporary sociality, experienced simultaneously in different sites of consumption. By drawing critically on the work of Augé and his contrast between places and nonplaces, these ideas are then put to work empirically in an examination of contemporary food shopping in Germany, focusing particularly on notions of consumer trust. A practice-based and ethnographically informed account of food shopping in Germany shows how distinctions between ‘traditional’ and ‘modern’ forms of consumption involve historicised accounts of contemporary consumption spaces and their associated socialities rather than referring to historical differences per se

Re-examining prophylactic cranial irradiation in small cell lung cancer: a systematic review and meta-analysisResearch in context

Summary: Background: Patients with small cell lung cancer (SCLC) are at high risk for brain metastases. Prophylactic cranial irradiation (PCI) is recommended in this population to reduce the incidence of brain metastases and prolong survival. We aimed to assesses the efficacy of PCI in this population in the era of routine brain imaging. To our knowledge, this is the first systematic review and meta-analysis to examine the use among patients who were radiographically confirmed not to have brain metastases after completion of first-line therapy. Methods: In this systematic review and meta-analysis, cohort studies and controlled trials reporting on the use of PCI for patients SCLC were identified in EMBASE, MEDLINE, CENTRAL, and grey literature sources. The literature search was conducted on November 12, 2023. Summary data were extracted. Random-effects meta-analyses pooled hazard ratios (HR) for the primary outcome of overall survival between PCI and no intervention groups. This study is registered with the Open Science Framework, DOI:10.17605/OSF.IO/BC359, and PROSPERO, CRD42021249466. Findings: Of 4318 identified records, 223 were eligible for inclusion. 109 reported on overall survival in formats amenable to meta-analysis; PCI was associated with longer survival in all patients with SCLC (HR 0.59; 95% CI, 0.55–0.63; p < 0.001; n = 56,770 patients), patients with limited stage disease (HR 0.60; 95% CI, 0.55–0.65; p < 0.001; n = 78 studies; n = 27,137 patients), and patients with extensive stage disease (HR 0.59; 95% CI, 0.51–0.70; p < 0.001; n = 28 studies; n = 26,467 patients). Between-study heterogeneity was significant when pooled amongst all studies (I2 = 73.6%; 95% CI 68.4%–77.9%). Subgroup analysis did not reveal sources of heterogeneity. In a subgroup analysis on studies that used magnetic resonance imaging to exclude presence of brain metastases at restaging among all patients, overall survival did not differ significantly between patients who did or did not receive PCI (HR 0.74; 95% CI, 0.52–1.05; p = 0.08; n = 9 studies; n = 1384 patients). Interpretation: Our findings suggested that administration of PCI is associated with a survival benefit, but not when considering studies that radiographically confirmed absence of brain metastases, suggesting that the survival benefit conferred by PCI might be therapeutic rather than prophylactic.
