Under the Convention against Torture, if states know of torture having taken place, they have obligations to provide redress and rehabilitation for victims and pursue prosecution of those responsible. Despite this, the United States continues to detain prisoners who were subjected to years of CIA torture in Guantánamo Bay. The United States is pursuing the death penalty through the Military Commissions (MC) system which falls far short of any international standards for fair trial. Ongoing systematic physical and psychological abuse prolongs torture’s effects. We argue that the ongoing arbitrary detention, abuse, denial of healthcare, and the MCs constitute a regime of torture that persists today, with the acquiescence of successive US administrations, and with the collusion of multiple agencies of the US state. This regime is deliberately intended to keep CIA torture victims incommunicado as long as possible to prevent evidence of the worst excesses of CIA torture from ever coming to light. This regime has profound implications for human rights accountability and the rule of law. Our argument offers an opportunity to revisit the prevailing narrative in International Relations literature, which tends to view the CIA torture programme as an aberration, and its closure an indicator of the restoration of the anti-torture norm.

Astrobiology Graduates in Europe (AbGradE, pronounced ab-grad-ee) is an association of early-career scientists working in fields relevant to astrobiological research. Conceptualized in 2013, it was initially designed as a mini-conference or workshop dedicated to early-career researchers, providing a friendly environment where early-career minds would be able to present their research without being intimidated by the possibility of facing a more traditional audience, composed mainly of senior scientists. Within the last couple of years, AbGradE became the first point of call for European, but also for an increasing number of non-European, early-career astrobiologists. This article aims to present how AbGradE has evolved over the years (in its structure and in its way of organizing events), how it has adapted with the COVID-19 pandemic, and what future developments are considered.

Gastric bypass surgery (GB) is a successful treatment for obesity(1). Following the procedure, patients report changes in preference away from palatable high fat (HF), high sugar (HS) foods that may contribute to weight loss(2). The aim of this work is to examine the relationship between changes in reported ‘liking’ (hedonic) and ‘wanting’(motivation) for HF, HS food and 24hr dietary intake post-GB. 15 GB patients (BMI: 41.7 ± 11.54kg/m2, 73% female) and 15 time-matched controls (BMI: 25.08 ± 4.37 kg/m2, 73% female) were recruited as part of a larger residential study and observed for 3 days at each of 3 time points; 1-month pre-surgery, 3-months post-surgery and 1 yr post-surgery. Covert, objective assessment of 24hr dietary intake was on day 2 of each visit using weighed food records. Participants had ad-libitum access to foods pre-determined by food preference questionnaires and proportionally represented by 6 macronutrient groups (HF/HS, HF/high CHO, HF/high protein, low fat/HS, low fat/high CHO, low fat/high protein). ‘Liking’ and ‘wanting’ was measured using the Leeds Food Preference Questionnaire (LFPQ)(3), a validated measure that uses visual analogue scales to determine explicit liking and wanting for food. Implicit preferences are determined using response and reaction time in a forced-choice task. GB patients significantly reduced their overall energy intake (EI) from baseline to three months (-6.9 ± 8.1MJ/d p = > 0.001) and 1 yr post-surgery (-5.3 ± 7.5MJ/d, p = 0.01) compared to controls. At 3mths post-GB, there was no significant relationship between changes in preference for HS food and changes in %EI from sugar (R2 = 0.97, F(3,26) = 0.94 p = 0.44) or from HS foods (R2 = 0.87, F(3,26) = 0.83, p = 0.49). Changes in preferences for HF food at 3mths post-surgery were not significantly related to %EI from fat (R2 = 0.16, F(3,26) = 1.66, p = 0.2) or HF food (R2 = 0.18, F(3,26) = 0.16, p = 0.93). These associations remained at 1 yr post-surgery. In conclusion, previous observations based on self-reported food intake have found changes in preference for HF, HS food that may contribute to weight loss in GB. In contrast, our results show no significant relationship between changes in preference and changes in dietary intake post-surgery. Further research using direct, objective measures of dietary intake is needed to elucidate further changes in dietary intake post-GB.

Bariatric surgery, including Gastric Bypass (GBP) Surgery, is the most efficient modality to manage severe obesity. Resting Energy Expenditure (REE) is an area of interest in the context of weight loss (WL) as it has been postulated to be an independent predictor of WL success following GBP. As such, the aim of this study is to investigate the impact of REE on WL following GBP. 31 GBP patients (77.4% females BMI 45.5 ± 7.0kg/m2 ; 47.3 ± 11.6y) and 32 weight-stable controls (46.9% females; BMI 27.0 ± 4.6kg/m2 ; 41.1 ± 13.5y) were assessed at one-month pre-surgery and at 3 and 12-months post-surgery. Fat mass (FM) and fat-free mass (FFM) were measured using dual energy X-ray absorptiometry (Lunar iDXA, GE Healthcare). REE was measured under standardised conditions using indirect calorimetry (ECAL, Metabolic Health Solutions). Statistical analyses were performed with SPSS v24.0, Armonk, NY. Multiple regression analysis showed that FM (P = 0.001), FFM (P < 0.0001) and gender (P = 0.012) significantly predicted the interindividual variability in REE. Total body weight (TBW) was removed from the model due to collinearity. Adjusted-REE values were then generated using the above predictor variables. Low-REE and high-REE groups were created using within-group adjusted-REE split. At both follow-ups (3- and 12-months post-surgery), patients had a greater reduction in TBW, FM, FFM, measured-REE and adjusted-REE values compared with controls (P < 0.0001). There was also no significant difference between measured and adjusted-REE values at all time-points (P > 0.05). Patients with high REEs at baseline lost more TBW than those in the low-REE group at 3-months post-surgery (-24.9 ± 6.5 kg vs. -16.6 ± 7.0 kg; P = 0.005) and 12-months post-surgery (-41.3 ± 12.5 kg vs. -25.8 ± 10.4.0 kg; P = 0.003). There was no significant difference in mean TBW changes for controls in the low-and high-REE groups at both follow-ups. Patients with high REEs at 3-months post-surgery did not lose more TBW than those in the low-REE group at 12-months post-surgery (-30.1 ± 12.8 kg vs. -38.6 ± 14.4 kg; P = 0.155). Similarly, there was no difference in mean TBW reduction between controls in the low- and high-REE groups (P = 0.115). Thus while patients with a high adjusted-REE value at baseline (> 9746.6kJ/day) lost more weight at 3- and 12-months post-GBP, it is plausible that from the third to the 12th month post-surgery, other key drivers of weight loss, particularly the reduction in energy intake are more important in predicting WL. Further research with a larger sample size is required to increase the chances of detecting a true effect.

Pre-pregnancy obesity is associated with a 2-fold increased risk of Neural Tube Defects (NTD), an effect not explained by lower dietary folate intake, or non-use of folic acid supplements (as recommended globally to women before and in early pregnancy for NTD prevention). While the exact mechanism linking NTD and obesity is poorly understood, it is possible that a compromised status or metabolism of folate and/or of the closely related micronutrients (vitamin B12, B6 and riboflavin) may be involved. To date however, this hypothesis has not been adequately explored. This study therefore aimed to investigate the relationship of obesity with folate and related B vitamin biomarkers in a representative cohort of non-pregnant UK women of reproductive age. Data were accessed from the most recent UK National Diet and Nutrition Survey (NDNS; Years 7–8; 2015–16), a rolling cross-sectional survey designed to gather information from a representative sample of the UK population on nutrient intakes, food consumption and nutritional status. Data for women aged 16–45 years (non B vitamin supplement users; n 364), were extracted on: anthropometry (height, weight, body mass index [BMI] and waist circumference [WC]), dietary intakes of B vitamins and biomarkers for serum and red blood cell folate, vitamin B12 (total serum B12 and holotranscobalamin), vitamin B6 (plasma pyridoxal-5-phosphate [PLP]) and riboflavin (erythrocyte glutathione reductase activation coefficient EGRAac]). Prevalence of overweight and obesity (i.e. BMI: 25–30kg/m2 and > 30kg/m2) was 28% and 22% respectively, whilst abdominal obesity (i.e. WC > 88cm) was present in 31% of the women. Total serum B12 (r -0.215, P 0.012) and PLP (r -0.270, P 0.002) were negatively correlated with WC, with similar, albeit weaker, correlations found for BMI. Correspondingly, women with abdominal obesity compared to those without, had a lower status of total serum B12 (Median values of: 212 v 249 v pmol/L; P 0.049), B6 (31.5 v 40.5 nmol/L; P 0.002) and EGRac (1.43 v 1.36; P 0.031). No differences in B vitamin dietary intake were observed by categories of abdominal obesity. Abdominal obesity may be a risk factor for low status of both vitamins B12 and B6, independently of dietary intake. Further investigation to elucidate the potential underlying mechanism is warranted. These findings also highlight the importance of taking abdominal obesity into account, in addition to BMI, when examining possible adverse impacts of obesity on micronutrient status.

The bran and particularly the aleurone fraction of wheat are high in betaine and other physiological methyl donors, which may exert beneficial physiological effects. We conducted two randomised, controlled, cross-over postprandial studies to assess and compare plasma betaine and other methyl donor-related responses following the consumption of minimally processed bran and aleurone fractions (study A) and aleurone bread (study B). For both studies, standard pharmacokinetic parameters were derived for betaine, choline, folate, dimethylglycine (DMG), total homocysteine and methionine from plasma samples taken at 0, 0·5, 1, 2 and 3 h. In study A (n 14), plasma betaine concentrations were significantly and substantially elevated from 0·5 to 3 h following the consumption of both bran and aleurone compared with the control; however, aleurone gave significantly higher responses than bran. Small, but significant, increases were also observed in DMG measures; however, no significant responses were observed in other analytes. In study B (n 13), plasma betaine concentrations were significantly and substantially higher following consumption of the aleurone bread compared with the control bread; small, but significant, increases were also observed in DMG and folate measures in response to consumption of the aleurone bread; however, no significant responses were observed in other analytes. Peak plasma betaine concentrations, which were 1·7–1·8 times the baseline levels, were attained earlier following the consumption of minimally processed aleurone compared with the aleurone bread (time taken to reach peak concentration 1·2 v. 2·1 h). These results showed that the consumption of minimally processed wheat bran, and particularly the aleurone fraction, yielded substantial postprandial increases in plasma betaine concentrations. Furthermore, these effects appear to be maintained when aleurone was incorporated into bread.

Studies have found that moral disengagement plays a significant role in the continuation of bullying situations (Bonanno, 2005); however, the moral stance of cyber-bystanders — those who witness online bullying — is not yet clear. While research into traditional face-to-face bullying reported that peers would probably or certainly intervene to support victims in 43% of cases (Rigby & Johnson, 2006) actual intervention is reportedly much less (Atlas & Pepler, 1998; Craig & Pepler, 1997). Little is known, however, about the attitudes and behaviours of bystanders or witnesses when online, or their probable intentions to intervene. This study employed three digital animations of typical cyberbullying scenarios to explore young people's views of cyber-bystanders. Youth from Years 8–12 (mean age 15.06, N = 961) from one metropolitan secondary school in Adelaide, South Australia, completed an online survey after watching vignettes. To shed light on the rationale and thinking behind their understanding of bystanders and moral dis/engagement when online, this article reports on the qualitative responses from young people in relation to one of these animations/vignettes. The findings suggest that young people perceive cyber-bystanders to have the capacity to morally engage in cyberbullying incidents; however, there are various barriers to their active positive engagement. The implications can inform educators and school counsellors about possible ways to support students to intervene when they witness cyberbullying.

Observational data show an inverse association between the consumption of wholegrain foods, and inflammation and related diseases. Although the underlying mechanisms are unclear, wholegrains, and in particular the aleurone layer, contain a wide range of components with putative antioxidant and anti-inflammatory effects. We evaluated the effects of a diet high in wheat aleurone on plasma antioxidants status, markers of inflammation and endothelial function. In this parallel, participant-blinded intervention, seventy-nine healthy, older, overweight participants (45–65 years, BMI>25 kg/m2) incorporated either aleurone-rich cereal products (27 g aleurone/d), or control products balanced for fibre and macronutrients, into their habitual diets for 4 weeks. Fasting blood samples were taken at baseline and on day 29. Results showed that, compared to control, consumption of aleurone-rich products provided substantial amounts of micronutrients and phytochemicals which may function as antioxidants. Additionally, incorporating these products into a habitual diet resulted in significantly lower plasma concentrations of the inflammatory marker, C-reactive protein (P = 0·035), which is an independent risk factor for CVD. However, no changes were observed in other markers of inflammation, antioxidant status or endothelial function. These results provide a possible mechanism underlying the beneficial effects of longer-term wholegrain intake. However, it is unclear whether this effect is owing to a specific component, or a combination of components in wheat aleurone.
