Background Assessment of liver lesions is constrained as CT radiation doses are lowered; evidence suggests deep learning reconstructions mitigate such effects. Purpose To evaluate liver metastases and image quality between reduced-dose deep learning image reconstruction (DLIR) and standard-dose filtered back projection (FBP) contrast-enhanced abdominal CT. Materials and Methods In this prospective Health Insurance Portability and Accountability Act-compliant study (September 2019 through April 2021), participants with biopsy-proven colorectal cancer and liver metastases at baseline CT underwent standard-dose and reduced-dose portal venous abdominal CT in the same breath hold. Three radiologists detected and characterized lesions at standard-dose FBP and reduced-dose DLIR, reported confidence, and scored image quality. Contrast-to-noise ratios for liver metastases were recorded. Summary statistics were reported, and a generalized linear mixed model was used. Results Fifty-one participants (mean age ± standard .001). Conclusion Deep learning image reconstruction (DLIR) improved CT image quality at 65% radiation dose reduction while preserving detection of liver lesions larger than 0.5 cm. Reduced-dose DLIR demonstrated overall inferior characterization of liver lesions and reader confidence. Clinical trial registration no.

Biomass ash is a waste obtained from thermal treatment of guishe (a by-product of natural fiber), and clay is collected from local soils. Several trials were performed to assess the influence of the addition of clay and guishe-ash on seeds germination, seedling growth, and production yield. The decrease in the values of these variables was considered an indicator of toxicity. The obtained results showed that based clay/ash materials positively affect germination (average ∼90% and six materials allow obtaining 90%) and seedlings growth (an increase of ∼20% in height and more than 50% in fresh air corpuscular weight). However, applying these materials on the production stage induces minor positive effects on fruit diameter, locule number, pericarp thickness, and the number of seeds per fruit. Also, adverse effects (first harvest yield, number of fruits, fresh mass of ripe fruits, lycopene content) were observed. To valorize biomass ash, its combination with other materials such as clay could be an alternative to improve tomato production.Given the possible benefits of phytoextraction, this study evaluated the potential of nine plant species for phytoaccumulation/co-accumulation of selected nutrients, rare earth elements, germanium, and potentially toxic elements. Plants were grown on 2 kg potted soils for 12 weeks in a greenhouse, followed by a measurement of dry shoot biomass. Subsequently, elemental concentrations were determined using inductively coupled mass spectrometry, followed by the determination of amounts of each element accumulated by the plant species. Results show varying accumulation behavior among plants for the different elements. Fagopyrum esculentum and Cannabis sativa were better accumulators of most elements investigated except for chromium, germanium, and silicon that were better accumulated by Zea mays, the only grass species. F. esculentum accumulated 9, 24, and 10% of Copper, Chromium, and Rare Earth Elements in the mobile/exchangeable element fraction of the soils while Z. mays and C. sativa accumulated amounts of Cr and Ge ∼58 and 17% (for Z. mays) and 20 and 9% (for C. sativa) of the mobile/exchangeable element fraction of the soils. Results revealed co-accumulation potential for some elements e.g., (1) Si, Ge, and Cr, (2) Cu and Pb, (3) P, Ca, Co, and REEs based on chemical similarities/sources of origin.The current arricle describes a novel recruitment protocol for collecting data from sexual assault and intimate partner violence survivors referred to research studies by individuals to whom they had previously disclosed. Challenges in both recruiting participants and interpreting data are described. Only 35.8% of cases had usable data for both survivors and disclosure recipients, suggesting that this referral method had limited success in recruiting matched pairs. Suggestions for modifications to improve the protocol for future research are offered. Potential advantages and drawbacks of various methods for recruiting dyads are described in order to facilitate future research on survivors' disclosure processes, social reactions, and the influence of social reactions on survivor recovery.Background Diet is a significant contributor to health and wellbeing of individuals. Aim In this study we investigated patterns of dietary intakes, levels of nutrient inadequacies and associated sociodemographic, anthropometric and lifestyle factors among adults in Trinidad and Tobago. Method The study was cross-sectional in nature. A convenience sample of 11783 persons from districts throughout Trinidad and Tobago completed a self-administered questionnaire comprising socio-demographic and lifestyle items. Anthropometry was self-reported with 15% of participants having measurements done according to recommended procedures. Dietary patterns were determined by principal component analysis (PCA) while nutrient intakes and adequacy were assessed using the NutriGenie 7.0 software and nutrient adequacy ratio (MAR) respectively. Foods were categorised as unprocessed/minimally processed and processed/ultra-processed. The University of The West Indies Ethics Committee approved the study. Results Approximately 72.5% of participants met the Goldberg criteria for plausible reporting. The three predominant dietary patterns 'Typical', 'Fruits and Vegetables', and 'High Fat' explained 45% of the total variance in foods consumed. Processed/ultra-processed foods accounted for most of the energy (80%) and nutrients consumed. Nutrient inadequacies were observed for potassium, vitamins B12, D, E, K, fibre, magnesium; and iron among females. The mean adequacy ratio (MAR) for participants was 67%. MAR was positively associated with predominant dietary patterns independent of socioe demographic and lifestyle factors (p  less then  0.001). Conclusion Irrespective of their nature, the predominant dietary pattern was associated with nutrient adequacy among participants. Reducing the risk of inadequate nutrient intakes may be addressed by increasing availability, access and consumption of appropriate sources of these micronutrients.Objectives The Do-Not-Resuscitate (DNR) order is part of most hospitals' policies on the process of making and communicating decisions about a patient's resuscitation status. Yet it has not become a part of our society's ritual of dying in the Middle East especially among children. Given the diversity of pediatric patients, the DNR order continues to represent a challenge to all parties involved in the care of children including the medical team and the family. Methods This was a retrospective review of the medical charts of patients who had died in the pediatric intensive care unit (PICU) of a tertiary academic institution in Beirut, Lebanon within the period of January 2012 and December 2017. Results Eighty-two charts were extracted, 79 were included in the analysis. Three were excluded as one patient had died in the Emergency Department (ED) and 2 charts were incomplete. Most patients were male, Lebanese, and from Muslim families. These patients clinically presented with primary cardiac and oncological diseases or were admitted from the ED with respiratory distress or from the operating room for post-operative management. The primary cause of death was multiorgan failure and cardiac arrest. Only 34% of families had agreed to a DNR order prior to death and 10% suggested "soft" resuscitation. Most discussions were held in the presence of the parents, the PICU team and the patient's primary physician. Conclusions The DNR order presents one of the most difficult challenges for all care providers involved, especially within a culturally conservative setting such as Lebanon. As the numbers suggest, it is difficult for parents to reach the decision to completely withhold resuscitative measures for pediatric patients, instead opting for "soft" resuscitations like administering epinephrine without chest compressions.Background Green tea, obtained from the plant Camellis sinensis, is one of the oldest drinks in the world and contains numerous bioactive compounds. Studies have demonstrated the efficacy of green tea in preventing obesity and cardiovascular diseases that may be related to the reduction of lipid levels. Aim This study aimed to evidence, through a systematic review, the therapeutic potential of green tea on the lipid profile in preclinical studies in obese animals and clinical studies in obese individuals. Methods This systematic review follows the recommendations of the preferred report items for systematic reviews and meta-analyses. The electronic databases, PubMed (Medline), Science Direct, Scopus, and Web of Science were consulted. Articles from January 2009 to December 2019 were selected. Results This search resulted in twenty-nine articles were included cirtically reviewed. In experimental studies, green tea administration has been shown to reduce total cholesterol, triglycerides and low-density lipoprotein cholesterol in animals exposed to obesity-inducing diet. In humans' studies green tea was not shown to be effective for obese lipid control. Because supplementation with green tea extract reduced total cholesterol, triglycerides, low-density lipoprotein for three months at a specific dose. Conclusion Therefore, green tea appears to act as a protective agent for dyslipidemia in obesity-induced animals. In human studies, green tea has not been shown to be effective in controlling obese lipids.

To determine the effects of neuromuscular electrical stimulation on disabilities and activity limitation of individuals affected by chronic obstructive pulmonary disease.

MEDLINE, PEDro database, Cochrane Controlled Trials Register, and SciELO, were searched from inception until October 2021.

Inclusion criteria were patients with COPD, randomized controlled trials comparing neuromuscular electrical stimulation alone or combined conventional pulmonary rehabilitation and neuromuscular electrical stimulation versus control or sham or pulmonary rehabilitation in disabilities and activity limitation in COPD. There were no mandatory language or publication date restrictions. Two reviewers selected studies independently. Weighted mean differences and 95% confidence intervals were calculated.

32 studies met the study criteria, including 1.269 participants. Neuromuscular electrical stimulation improved exercise capacity (MD 1.10, 95% CI 0.33, 1.86, N = 147), and muscle strength (0.53, 95% CI 0.20, 0.87, N = 147) compared to sham group. Combined neuromuscular electrical stimulation and conventional rehabilitation improved exercise capacity (MD 34.28 meters, 95% CI 6.84, 61.73, N = 262) compared to conventional rehabilitation alone. No adverse events were reported.

Neuromuscular electrical stimulation resulted in small improvement in disabilities and activity limitation (below the MCID) in COPD. Thus, the inclusion of neuromuscular electrical stimulation in rehabilitation programs must consider the cost Because of inadequate methodological conduction and reporting of methods, some studies were of low quality.
