Previous attempts to classify cancer cachexia (CC) have demonstrated limitations regarding stages and diagnostic criteria. This study aims to develop and validate a new staging system for CC in patients with incurable cancer.

This is an analysis of a database from a prospective cohort study of 1325 patients with advanced cancer referred for palliative care between 2016 and 2020. The cohort was randomly divided into two groups Development (882 patients) and validation (443 patients) sets. A hierarchical cluster analysis was performed to distinguish different stages of CC in the development set. Next, the optimal cutoff points and ideal combinations of the most important factors associated with the CC groups (clusters) were ascertained. Finally, the relationship between the CC stages determined using the new system and body composition, quality of life, and overall survival was verified with the validation set.

The new system classified CC into three stages Precachexia (10.8%), cachexia (57.8%), and refractory cachexia (31.4%), based on a combination of percentage weight loss in the past 6 mo (<15 or ≥15), body mass index (<21.0, 21.0-26.4, >26.4 kg/m
), and mid-upper-arm muscle area (≥38.0/≥35.5 or <38.0/<35.5 cm
in men/women, respectively). The new staging system enabled a clear classification of patients into three CC groups according to the outcomes analyzed. Outcomes of patients with refractory cachexia were significantly worse than those in the other groups.

This study presents a useful, valid system for CC staging in the clinical setting, and is also capable of predicting outcomes, including quality of life and overall survival.

Promising evidence suggests beneficial health effects of arabinogalactan, but little is known about the effect of this non-digestible carbohydrate on the gut microbiota, a crucial mediator of human health. The objective of this study was to investigate the effect of an arabinogalactan product (ResistAid) on the fecal microbiome and short-chain fatty acids and gastrointestinal tolerance in healthy adults in a randomized, double-blind, crossover trial.

Thirty adults were randomly assigned to consume 15 g/d maltodextrin (control) or ResistAid for 6 wk.

At week 6, compared to placebo, ResistAid supplementation led to a significant decrease in the ratio of fecal Firmicutes to Bacteroidetes, driven by an increase in Bacteroidetes and a decrease in Firmicutes. Moreover, the relative abundance of Bifidobacterium tended to increase with ResistAid supplementation. Additionally, ResistAid significantly decreased the α-diversity of the fecal microbiome.

Malnutrition and vitamin deficiency are growing concerns in the clinical management of children with autism spectrum disorder (ASD). This case report presents a boy with ASD who developed vitamin A deficiency during follow-up.

A 7-y-old boy had been diagnosed with ASD and developmental delay at age 18 mo. He developed convulsions associated with hypocalcemia and vitamin D deficiency at 3 y of age. Although vitamin D supplementation was continued, he was only able to eat rice, green tea, and fried potatoes from 3 y of age to age 7 y. check details He had started rubbing his eyes and had refused to open his eyes 9 mo before. An ophthalmologic examination showed bilateral corneal ulcers and right corneal perforation. Vitamin A was immediately supplemented with a nasogastric tube; however, his right eye was surgically enucleated against the persistent infection.

A search of the relevant literature from 1993 to 2020 identified 11 cases of patients with ASD (5-17 y of age) who developed vitamin A deficiency owing to malnutrition. Only 4 cases (36%) had a full recovery in visual acuity.

Vitamin A deficiency frequently causes irreversible visual impairment in children with ASD. Vigilant monitoring of vitamin levels prevents unfavorable outcomes in children with ASD and difficulty in food intake.

This study explores the effects of fecal microbiota from children with vitamin A (VA) deficiency on colonic mucosal barrier function.

The composition of gut microbes was identified in children with different VA levels, then feces from children with normal VA or VA deficiency was collected separately and transplanted into germ-free (GF) mice, respectively. Three weeks after transplantation, the colon morphology, colonic tight junction proteins, gut microbes, and metabolites were evaluated.

In children, Bifidobacterium and Bacteroides were positively correlated with VA levels. Colonization of VA deficiency fecal microbiota markedly impaired colonic development in GF mice, down-regulated colonic tight junction-related proteins occludin and claudin-1, and reduced immunoglobulin A secretion. Furthermore, fecal microbiota transplantation with different VA levels altered composition of gut microbes and bile acid metabolism pathways in GF mice.

These data suggest that fecal microbiota from children with VA deficiency attenuates colonic barrier function in GF mice, which may be achieved by changing the bile acid metabolic pathways.

Malnutrition negatively affects the quality of life, survival, and clinical outcome of patients with cancer. Home artificial nutrition (HAN) is an appropriate nutritional therapy to prevent death from cachexia and to improve quality of life, and it can be integrated into a home palliative care program. The choice to start home enteral nutrition (HEN) or home parenteral nutrition (HPN) is based on patient-specific indications and contraindications. The aim of this observational study was to analyze the changes that occurred in the criteria for choosing the access route to artificial nutrition during 30 y of activity of a nutritional service team (NST) in a palliative home care setting, as well as to compare indications, clinical nutritional outcomes, and complications between HEN and HPN.

The following parameters were analyzed and compared for HEN and HPN tumor site and metastases; nutritional status (body mass index, weight loss in the past 6 mo); basal energy expenditure and oral food intake; Karnofsky pcomparable between HEN and HPN. In patients who maintained food oral intake, supplemental parenteral nutrition improved weight, performance status, and survival better than other types of HAN.
Soy-based formula has evolved in usage and processing technology since its introduction in 1909, and has been used as substitute formula for infants or children with cow milk allergy since 1929. At present, personal opinions, religious background, availability, palatability, and cost are part of the reasons soy-based formula is chosen. Technology in processing soy-based formula has evolved from using soy flour to soy protein isolate, which provides advantages. However, concerns remain regarding the impact of its use on the growth and development of children.

An expert meeting, attended by 12 experts, was initiated in Jakarta, Indonesia, to obtain an evidence-based consensus on the role of soy protein isolate formula, as well as its nutritional value to support growth and development.

Ensuring that plant-based formula (i.e., soy protein isolate formula) is fortified with key nutrients, such as calcium, iron, and dietary fiber is important.

Consensus was achieved, concluding that soy protein isolate formula is safe, affordable, and an alternative option for cow's milk-based formula for term infants.

The program, iPick, presented here provides a scripting tool and a graphical user interface (GUI), which allow the user to perform interactive and intuitive peak picking and validation. The click-and-run GUI requires no computer programming skills, while the scripting tool can be used by more advanced users to customize the application. If used with a multi-core CPU, the multiprocessing feature of iPick reduces the processing time significantly by invoking parallel computing. The GUI is a plugin, compatible with the popular NMRFAM-SPARKY software package and its newly released successor, the POKY software. Features implemented in iPick include automated noise level detection and threshold setting, cross-validation against multiple spectra, and a method for quantifying peak reliability. The iPick software is cross-platform, open-source, and freely available from https//github.com/pokynmr/ipick.Mercury (Hg) is a prominent environmental contaminant and can cause various subcellular effects. Elucidating the different subcellular toxicities of inorganic Hg (Hg2+) and methylmercury (MeHg) is critical for understanding their overall cytotoxicity. In this study, we employed aggregation-induced emission (AIE) probes to investigate the toxicity of Hg at the subcellular level using an aquatic embryonic zebrafish fibroblast cell line ZF4 as a model. The dynamic monitoring of lysosomal pH and the mapping of pH distribution during Hg2+ or MeHg exposure were successfully realized for the first time. We found that both Hg2+ and MeHg decreased the mean lysosomal pH, but with contrasting effects and mechanisms. Hg2+ had a greater impact on lysosomal pH than MeHg at a similar intracellular concentration. In addition, Hg2+ in comparison to MeHg exposure led to an increased number of lysosomes, probably because of their different effects on autophagy. We further showed that MeHg (200 nM) exposure had an inverse effect on mitochondrial respiratory function. A high dose (1000 nM) of Hg2+ increased the amount of intracellular lipid droplets by 13%, indicating that lipid droplets may potentially play a role in Hg2+detoxification. Our study suggested that, compared with other parameters, lysosome pH was most sensitive to Hg2+ and MeHg. Therefore, lysosomal pH can be used as a potential biomarker to assess the cellular toxicity of Hg in vitro.Targeted therapy of cancer is considered as promising alternative approach to conventional chemotherapy and radiotherapy. Recent advancements in biotechnology have significantly improved the identification of novel radiopharmaceuticals allowing for more accurate imaging and therapeutic targeting of epithelial tumors. The successful development of radiotracers critically depends on the selection and validation of the tumor-specific target structure, the technical approach employed for the identification of a target-specific ligand, and the evaluation and improvement of the binding properties and the pharmacokinetic profile of the ligand by biotechnological procedures or chemical modification, respectively. Employing rational design of a quinoline-based fibroblast activation protein inhibitor (FAPI) and 'high-through put' display technology using a sunflower trypsin inhibitor1-based peptide library, several FAPI derivatives and a novel αvβ6 integrin-binding peptide (SFITGv6) were identified. FAPI and SFITGv6 represent powerful radiopharmaceuticals for diagnostic imaging and/or endoradiotherapy of FAP- and αvβ6 integrin-expressing epithelial tumors, respectively.
