e is an improvement in nutritional status, lung function, quality of life, or survival. Furthermore, due to the unclear risks of bias in the included trials, we are unable to make firm conclusions based on the evidence reported therein. We therefore recommend that large, multicentre, randomised controlled clinical trials are undertaken to evaluate these interventions.

Trials have shown limited evidence that agents that reduce gastric acidity are associated with improvement in gastro-intestinal symptoms and fat absorption. Currently, there is insufficient evidence to indicate whether there is an improvement in nutritional status, lung function, quality of life, or survival. Furthermore, due to the unclear risks of bias in the included trials, we are unable to make firm conclusions based on the evidence reported therein. We therefore recommend that large, multicentre, randomised controlled clinical trials are undertaken to evaluate these interventions.

Accurate deformable registration between computed tomography (CT) and cone-beam CT (CBCT) images of pancreatic cancer patients treated with high biologically effective radiation doses is essential to assess changes in organ-at-risk (OAR) locations and shapes and to compute delivered dose. This study describes the development and evaluation of a deep-learning (DL) registration model to predict OAR segmentations on the CBCT derived from segmentations on the planning CT.

The DL model is trained with CT-CBCT image pairs of the same patient, on which OAR segmentations of the small bowel, stomach, and duodenum have been manually drawn. A transformation map is obtained, which serves to warp the CT image and segmentations. In addition to a regularity loss and an image similarity loss, an OAR segmentation similarity loss is also used during training, which penalizes the mismatch between warped CT segmentations and manually drawn CBCT segmentations. At test time, CBCT segmentations are not required as they are inst DSC and smaller interquartile variation than either MMFF (paired t-test P<10

for both type of OARs) or LDDMM (P<10

and P=0.03 respectively). Root-mean-square deviation (RMSD) of DL-predicted change in small bowel volume relative to reference was 22% less than for MMFF (P=0.007). RMSD of DL-predicted stomach/duodenum volume change was 28% less than for LDDMM (P=0.0001). RMSD of DL-predicted D(5cc) in small bowel was 39% less than for MMFF (P=0.001); in stomach/duodenum, RMSD of DL-predicted D(5cc) was 18% less than for LDDMM (P<10

).

The proposed deep network CT-to-CBCT deformable registration model shows improved segmentation accuracy compared to intensity-based algorithms and achieves an order-of-magnitude reduction in processing time.

These results should be considered to characterize pureed and transitional foods such as cereal-based foods for dysphagia patients using specific sensory texture descriptors.Nucleocytosolic transport, a membrane process, is impaired in motor neurons in amyotrophic lateral sclerosis (ALS). This study analyzes the nuclear lipidome in motor neurons in ALS and examines molecular pathways linked to the major lipid alterations. Nuclei were obtained from the frozen anterior horn of the lumbar spinal cord of ALS patients and age-matched controls. Lipidomic profiles of this subcellular fraction were obtained using liquid chromatography and mass spectrometry. We validated the mechanisms behind presumable lipidomic changes by exploring ALS surrogate models including human motor neurons (derived from ALS lines and controls) subjected to oxidative stress, the hSOD-G93A transgenic mice, and samples from an independent cohort of ALS patients. Among the differential lipid species, we noted 41 potential identities, mostly belonging to phospholipids (particularly ether phospholipids, as plasmalogens), as well as diacylglycerols and triacylglycerides. Decreased expression of alkyldihydroxyacetonephosphate synthase (AGPS)-a critical peroxisomal enzyme in plasmalogen synthesis-is found in motor neuron disease models; this occurs in parallel with an increase in the expression of sterol carrier protein 2 (SCP2) mRNA in ALS and Scp2 levels in G93A transgenic mice. Further, we identified diminished expression of diacylglycerol-related enzymes, such as phospholipase C βI (PLCβI) and protein kinase CβII (PKCβII), linked to diacylglycerol metabolism. Finally, lipid droplets were recognized in the nuclei, supporting the identification of triacylglycerides as differential lipids. Our results point to the potentially pathogenic role of altered composition of nuclear membrane lipids and lipids in the nucleoplasm in the anterior horn of the spinal cord in ALS. Overall, these data support the usefulness of subcellular lipidomics applied to neurodegenerative diseases.

Many patients with cancer do not disclose complementary medicine use but want their physician's advice on this matter. This study evaluated whether using blended learning (e-learning plus a workshop) to train oncology physicians in providing advice on complementary and integrative medicine (CIM) therapies to their patients with cancer, in addition to distributing an information leaflet on reputable CIM websites, had different effects on patient-reported outcomes for the consultation than only distributing the leaflet.

In this multicenter, cluster-randomized trial, patients from private practices/hospital departments, recruited by 48 oncology physicians randomly allocated to an intervention group (CIM consultation plus information leaflet) or a control group (information leaflet), received CIM information. Patient-reported outcomes included satisfaction (Patient Satisfaction With Information on Cancer Treatment), readiness to make a decision (Preparation for Decision Making), and physician-patient communic consultations had positive effects on patient satisfaction, readiness to make decisions, and physician-patient communication.

This study evaluated a novel education intervention for training oncology physicians in providing CIM advice in routine care. Providing structured CIM consultations had positive effects on patient satisfaction, readiness to make decisions, and physician-patient communication.Climate change hampers food safety and food security. Crop breeding has been boosting superior quantity traits such as yield, but roots have often been overlooked in spite of their role in the whole plant physiology. click here New evidence is emerging on the relevance of root system architecture in coping with the environment. Here, we review determinants of root system architecture, mainly based on studies on Arabidopsis, and we discuss how breeding for appropriate root architecture may help obtain plants that are better adapted or resilient to abiotic and biotic stresses, more productive, and more efficient for soil and water use. We also highlight recent advances in phenotyping high-tech platforms and genotyping techniques that may further help to understand the mechanisms of root development and how roots control relationships between plants and soil. An integrated approach is proposed that combines phenotyping and genotyping information via bioinformatic analyses and reveals genetic control of root system architecture, paving the way for future research on plant breeding.Stomatal conductance (gs ) affects water use efficiency (WUE) through coordinating photosynthesis and transpiration and is regulated by chemical and/or hydraulic signals. However, the regulation mechanism of gs of tomato leaves has not been fully explored under combined water and salt stress. Here, we set up four salt treatments and two water treatments in a climate greenhouse and measured stomatal morphologies and conductance and other photosynthesis parameters. Water and salt stress reduced stomatal length (SL), width, perimeter, area (amax ), density (SD), and the maximum stomatal conductance (gsmax ). Water and salt stress had a separate weakening effect on net photosynthetic rate (A) and transpiration rate but interactively reduced gs . The contents of abscisic acid (ABA) and Na+ in tomato leaves increased with the NaCl concentration, while leaf water potential (Ψl ) and chlorophyll content decreased. Under full irrigation, gsmax was coordinated by SD and amax , and gs by ABA content under salt stress. Under water and salt combined stress, gsmax was affected by amax , and gs was coordinated with ABA and Ψl . The decrease of A was caused by both a reduction of chlorophyll content and gs under water and salt stress. Intrinsic WUE did not reduce under full irrigation or mild to moderate salt stress but decreased under a combination of water and severe salt stress, indicating that the leaves of the tested tomato cultivar performed better under moderate salt stress. Collectively, these results can provide useful insights for the efficient management of water and salt to adapt to drought and high salt environments.Girls and adolescents, aged 0-19 years make up almost 30% of the world's female population yet their specific healthcare needs often slip between the gaps of pediatrics and adult women's health. Pediatric and adolescent gynecology is the clinical field that endeavors to address the reproductive health needs of this age group. The environment and psychosocial well-being, social determinants of health, have direct bearing on reproductive health, affecting menstrual cycles, menstrual hygiene, and risks for unintended pregnancy and sexually transmitted infections. This narrative review will highlight common gynecologic conditions of adolescents, especially where diagnosis and management are distinct from adult women. It will also present preventive health strategies to improve reproductive health through vaccination, improved access to hygiene supplies and contraception.

The prevalence of food insecurity among undergraduate students is higher than the national average and associated with adverse academic outcomes. Our objective was to describe the prevalence of food insecurity, food access behaviors, and associations between food security status and well-being in a dental student population.

All dental students (N=328) enrolled in the College of Dentistry at the University of Iowa in the fall 2019 semester were invited to participate. The survey was designed to query demographic variables, food security status (i.e., the United States Department of Agriculture's 10-item Adult Food Security Module), and food- or hunger-related well-being (i.e., sleep, academic performance, and stress). The survey was administered using the Qualtrics survey platform. Following the initial invitation, students were sent two reminders and allowed 3 weeks for completion.

The survey response rate was 24.7%. Forty-seven percent of respondents were food insecure. Food insecure students were more likely to attend collegiate programming (e.
