Shift workers frequently experience sleepiness during night shifts, which may have consequences for performance. Sleep duration is often shortened after a night shift. Properly timed bright light treatment is efficient in delaying the circadian rhythm and can enhance alertness, increase performance and prolong sleep after night shifts. There is a lack of studies on light treatment to rotating shift workers. This study is a randomized controlled crossover trial evaluating the effect of bright light treatment on sleep and sleepiness in rotating shift workers with three consecutive night shifts. The aim is to evaluate whether bright light treatment improves adaptation to three consecutive night shifts (reduces sleepiness during night shifts and improves sleep after night shifts), as well as whether such treatment affects re-adaptation to a day-oriented schedule after the night shift period.
BACKGROUND: Sarcopenia has received increasing attention in non-small cell lung cancer (NSCLC). Red blood cell distribution width (RDW) is a significant component of the complete blood count and indicates the heterogeneity of erythrocyte volume. Little information is known about RDW in relation to sarcopenia in early-stage (IA-IIIA) NSCLC. The purpose of the present study was to investigate the association between RDW and sarcopenia risk in early-stage NSCLC patients.
METHODS: This study included 378 patients with pathologically confirmed stage IA-IIIA NSCLC. Sarcopenia was defined by measuring the skeletal muscle index (SMI) at the eleventh thoracic vertebra level. The maximum Youden index on the receiver operating characteristic (ROC) curve was used to estimate the cutoff value for RDW to predict sarcopenia. Logistic regression analyses were carried out to assess the independent risk factors for sarcopenia in NSCLC.
RESULTS: The ROC curve indicated that the best cutoff point for RDW to predict sarcopenia was 12.9 (sensitivity of 43.80% and specificity of 76.76%, respectively). Moreover, there were significant differences in hemoglobin (p < 0.001), comorbidities (p = 0.001), histological type (p = 0.002), and cancer stage (p = 0.032) between the high RDW and low RDW groups. Logistic regression analyses revealed that high RDW is an independent risk factor for sarcopenia in early-stage NSCLC.
CONCLUSION: RDW is associated with sarcopenia risk in early-stage NSCLC.
Study subjects assigned to the placebo dose arm took placebo capsules each day for 14 days. The capsules did not contain any VE303.
NEW MATERIAL:The proline derivative of formula I (R is lower alkyl; X is N-terminal protecting group in amino acid chemistry or acyl of amino acid having protecting group at N-terminal). EXAMPLE:p-Methoxybenzoyl-L-prolinal dimethylacetal. USE:A substance having proline endopeptidase inhibiting activity. A drug having anti-amnestic activity. A chemically stable compound can be produced by converting the aldehyde group of a prolinal derivative to acetal. PREPARATION:The prolinal derivative of formula I can be produced e.g. by subjecting a dialkylacetal of prolinal of formula II to amino acid protecting reaction.
OBJECTIVES: Several studies demonstrated the benefits of omega-3 fatty acids supplementation in chronic kidney disease (CKD) patients. The objective of this study was to investigate the effect of omega-3 fatty acids supplementation in body composition, specifically on the lean body mass and fat mass in hemodialysis patients.
METHODS: In this randomized, double-blind, placebo-controlled clinical trial, a total of 120 end-stage renal disease (ESRD) patients were randomly allocated into two groups. The intervention group has taken three grams of omega-3 fatty acids daily while the placebo group received three grams of medium chain triglycerides (MCT) as a placebo for a total of 2 months. The changes in the body mass index (BMI) and body composition (fat mass, muscle, and visceral fat) were assessed at baseline and following the intervention.
RESULTS: No significant difference was found in the mean of BMI, FAT, muscle, and visceral fat in the intervention group compared to the control group after the intervention. After two months of omega-3 fatty acid supplementation, the study found no statistically significant impact of omega-3 fatty acids supplementation on various indices of body composition. The effect of ω-3 supplementation in reducing visceral fat was close to significant (p=0.08).
CONCLUSIONS: This study suggests that there is currently inadequate evidence to support the effect of omega-3 fatty acid supplementation in improving anthropometric measurements in patients with CKD, except a partial effect on visceral fat. Further large-scale and long-term clinical trials are needed to confirm the present results.

The present disclosure is directed to methods and materials, including kits, for use in treating snakebites, bee stings, spider bites, and other envenomation or exposure to toxins not derived from animals. The methods and materials encompass proteases, which have been found to increase survival and reduce toxic effects, such as temperature loss, and, in experimental animals, death. The proteases have been found to be part of a protective mechanism associated with mast cell degranulation. Preferred proteases include certain proteases found in mast cells, such as chymases (chymotrypsin-like substrate specificity), carboxypeptidase A and tryptases (trypsin-like substrate specificity). Other proteases, such as carboxypeptidase B, chymotrypsin or papain may also be employed. Further provided are kits and dosage forms for convenient and rapid delivery of treatment in case of envenomation. Such dosage forms are based on internal, rather than topical delivery.
FIELD: medicine. SUBSTANCE: the method deals with obtaining medicinal preparations out of natural raw materials to be used then in industrial production of natural pulmonary surfactants. Bull's lungs should be reduced, then one should obtain aqueous-saline extract followed by its flow-type centrifuging at low rotations, then at high rotations - by extracting with chloroform mixtures with methanol and treatment of obtained extract with 0.1%-sodium chloride solution. After centrifuging the suspension lower layer of supernatant is removed, organic solvents are evaporated to obtain a target product to be resuspended in water and after detection of lipid phosphorus in obtained emulsion it should be packed into vials and lyophilized. The method enables to obtain quick output of product being about 2 g/kg initial raw material, on average. EFFECT: higher simplicity of the method.
Methodology: The two populations of patients, one treated with methadone, the other with HDB, will be recruited in accordance with the ethical principles of the declaration of Helsinki, during consultations at a center for addiction treatment. One hundred and ten patients will be included in each of the two populations. Written informed consent will be obtained from each patient. Anonymity will be respected at inclusion and throughout. Using a sample of hair, testing for and measurement of the principal drugs (opiates, cannabis, cocaine, amphetamines) and the specific marker of ethanol consumption, ethyl glucuronide, will be performed by chromatographic techniques (high-performance liquid chromatography and gas phase chromatography) together with detection by mass or tandem mass spectrometry. This non-invasive sampling is more informative than blood tests, as it gives a retrospective profile of an individual's consumption over several months. Treatment efficacy will also be assessed using Handelsman's subjective and objective opiate withdrawal scales. Lastly, polymorphisms of the metabolic enzymes of methadone and HDB will be sought by real-time PCR in a saliva sample, a method which gives similar results without the need for venous blood sampling.
Objective: To investigate the correlation between early energy supplement and bronchopulmonary dysplasia (BPD) in very preterm and very low birth weight infants. Methods: A retrospective cohort study design was used. A total of 939 preterm infants who were admitted to the Department of Neonatology of the West China Second Hospital of Sichuan University within 24 h after birth from January 2019 to December 2021 were enrolled in the study. They were born with a gestational age of <32 weeks and (or) a birth weight of <1 500 g. Of them, 250 preterm infants who developed BPD were enrolled in the BPD group, and each of them was matched to a preterm infant who did not develop BPD (matched for gestational age and birth weight) in the order of priority after calculating propensity score. Their total energy, enteral energy, parenteral energy, total fluid intake and energy per unit of fluid per week were collected within the first 2 weeks of life. The independent sample t-test or Mann Whitney U test was used for continuous variables, and the χ2 test for between-group comparisons of categorical variables. Univariate and multivariate Logistic regression analyses were used to explore the association between total energy and total fluid and BPD incidence, respectively. The dose-response relationship between parenteral energy and BPD was investigated by a generalized additive model, and the threshold effect of parenteral energy on BPD used a two-piecewise linear regression model. Results: The gestational age was (28.4±1.9) weeks in the BPD group and (29.5±1.3) weeks in the control group; the birth weight was (1 107±258) g in the BPD group and (1 324±261) g in the control group; and there were 140 males (56.0%) and 131 males (52.4%) in each group, respectively. An increase in energy per unit of fluid in the second week of life was associated with a reduced risk of BPD (OR=0.32, 95%CI 0.12-0.84, P=0.021), and an increase in total energy in the second week of life was also associated with a reduced risk of BPD, with total energy of >418-502 kJ/(kg·d) was significantly lower than when total energy was ≤334 kJ/(kg·d) (OR=0.15, 95%CI 0.03-0.85, P=0.033). There was no association between the average total fluid intake and BPD incidence (both P>0.05) in the first and second week. The increase in the proportion of parenteral energy to total energy in the second week of life was associated with an increased incidence of BPD (OR=8.45, 95%CI 2.14-33.32, P=0.003); specifically, the risk of BPD significantly increased when the parenteral energy was ≥305 kJ/(kg·d) (OR=1.02, 95%CI 1.01-1.03, P=0.003). Conclusions: Maintaining a high total energy supply in the early postnatal period in preterm infants may reduce the risk of BPD, but continued reliance on high parenteral energy to meet total energy requirements increases the risk of BPD, so enteral feeds should be initiated as early as possible and maximized as tolerated.

Peripheral artery disease (PAD) is a debilitating atherosclerotic disease caused by plaque development in the arteries leading to diminished skeletal muscle blood flow, oxygen delivery, and metabolic dysfunction during ambulation causing marked exercise intolerance. Veterans have a disproportionate risk of developing PAD compared to the general population because of higher levels of smoking, hypertension, diabetes, and obesity. Worryingly, the mortality rate for PAD in Veterans (\~30%) is nearly double that of the general population. Currently, the best treatment of PAD is exercise rehabilitation, however, issues with patient motivation and pain reduce the effectiveness of this treatment. There is a pressing, and unmet need to identify the sites and underlying mechanisms of the systemic dysfunction leading to exercise intolerance induced by PAD. Oxidative stress and inflammation play important roles in the development and progression of PAD. Critically, the peripheral vasculature (diminished blood flow) and mitochondria (diminished respiration) are primary determinants/mechanisms responsible for exercise intolerance in health and disease that are particularly vulnerable to elevations in oxidative stress and inflammation, making these likely sites of systemic dysfunction leading to exercise intolerance in Veterans with PAD. Any vascular or mitochondrial dysfunction would further augment oxidative stress and inflammation initiating a vicious cycle. It is the central hypothesis that increased endogenous antioxidant capacity and diminished inflammation will improve oxygen delivery and utilization during exercise, thus, increasing the efficacy of exercise rehabilitation due to increased adherence and exercise capacity. To test this hypothesis, the investigators will utilize the naturally-derived Nuclear Factor Erythroid-2-like 2 (Nrf2; the "master regulator of antioxidant enzymes") activator, PB125, to stimulate induction of endogenous antioxidants and decrease the activity of inflammatory pathways. Veterans with PAD will be randomly assigned to receive either PB125 or Placebo supplementation. Each Veteran will undergo three phases of testing: 1) baseline, 2) post 1 month of supplement loading, and 3) post 12 weeks of exercise rehabilitation with continued supplementation. Functional capacity and cognitive function (Aim 1), Vascular function and exercising hemodynamics (Aim 2), and in vivo and ex vivo mitochondrial respiration (Aim 3) will be assessed each phase. Monthly assessments of functional capacity, behavioral regulation, quality of life, and physical activity will track improvements across the trial. At the conclusion of these studies, the investigators will have expanded the knowledge of the mechanisms underlying exercise intolerance in Veterans suffering from PAD, and, more importantly from a clinical perspective, provided insight into a potential novel therapeutic treatment to improve exercise rehabilitation efficacy for this population. It is anticipated this advancement will contribute to advancing clinical practice in rehabilitative medicine, and ultimately, improving the quality of life for Veterans living with PAD.
BACKGROUND: Canine and human osteosarcoma are similar in clinical presentation and tumor genomics. Giant breed dogs experience elevated osteosarcoma incidence, and taller stature remains a consistent risk factor for human osteosarcoma. Whether evolutionarily conserved genes contribute to both human and canine osteosarcoma predisposition merits evaluation.
METHODS: A multi-center sample of childhood osteosarcoma patients and controls underwent genome-wide genotyping and imputation. Ancestry-adjusted SNP associations were calculated within each dataset using logistic regression, then meta-analyzed across the three datasets, totaling 1091 patients and 3026 controls. Ten regions previously associated with canine osteosarcoma risk were mapped to the human genome, spanning ∼6 Mb. We prioritized association testing of 5985 human SNPs mapping to candidate osteosarcoma risk regions detected in Irish wolfhounds, the largest dog breed studied. Secondary analyses explored 6289 additional human SNPs mapping to candidate osteosarcoma risk regions identified in Rottweilers and greyhounds.
RESULTS: Fourteen SNPs were associated with human osteosarcoma risk after adjustment for multiple comparisons, all within a 42 kb region of human Chromosome 7p12.1. The lead variant was rs17454681 (OR=1.25, 95 %CI: 1.12-1.39; P=4.1×10-5), and independent risk variants were not observed in conditional analyses. While the associated region spanned 2.1 Mb and contained eight genes in Irish wolfhounds, associations were localized to a 50-fold smaller region of the human genome and strongly implicate GRB10 (growth factor receptor-bound protein 10) in canine and human osteosarcoma predisposition. PheWAS analysis in UK Biobank data identified noteworthy associations of the rs17454681 risk allele with varied measures of height and pubertal timing.
CONCLUSIONS: Our comparative oncology analysis identified a novel human osteosarcoma risk allele near GRB10, a growth inhibitor that suppresses activated receptor tyrosine kinases including IGF1R, PDGFRB, and EGFR. Epidemiologists may benefit from leveraging cross-species comparisons to identify haplotypes in highly susceptible but genetically homogenous populations of domesticated animals, then fine-mapping these associations in diverse human populations.

EFFECT:The peptide hormone has retarded clearance and shows effectively its activity for a long period and has low toxicity and antigenecity.
Lithium belongs to a class of kinase-targeting therapies, including the diabetes medication exenatide and the cancer medication nilotinib, that have demonstrated promise as disease-modifying therapies for Parkinson's disease (PD). Exenatide was recently shown to engage protein kinase B (Akt) and provide significant symptomatic and possible disease-modifying benefit in PD in a phase 2 randomized controlled trial (RCT). Nilotinib engages c-Abelson kinase (c-Abl) and its disease-modifying effects are currently being investigated in two, phase 2 PD RCTs. Lithium targets Akt, glycogen synthase kinase-3 beta (GSK-3B, a downstream target of Akt) and cyclin-dependent kinase 5 (cdk5, a downstream target of c-Abl) in manners that recapitulate those of exenatide and nilotinib. Also, lithium inhibits inositol monophosphate leading to enhanced autophagy and reduced intracellular levels of alpha-synuclein (a-synuclein), which is believed to be a primary mediator of the progressive neurodegeneration in PD. In addition to a-synuclein, genome-wide association studies (GWAS) have implicated oligomeric tau in the pathogenesis of PD. Pathological mutations in leucine-rich repeat kinase 2 (LRRK2) are the most common genetic cause of a late-onset parkinsonism that is clinically indistinguishable from sporadic PD and very similar pathologically. Pathological LRRK2 mutations affect the activities of Akt, GSK-3B and cdk5 to greatly increase the formation of phosphorylated tau (p-tau) - the precursor to tau oligomer formation - and decrease the activity of the transcriptional cofactor B-catenin - which mediates the transcription of neuronal survival genes implicated in PD such as nuclear receptor related 1 (Nurr1). Through its ability to inhibit GSK-3B, lithium can enhance B-catenin-mediated activity and Nurr1 expression. Lithium was also effective in several PD animal models. Finally, both clinical trial and epidemiologic data suggest that lithium exposures of even \<1mg a day may provide significant disease-modifying effects in neurodegenerative diseases including PD.

The investigators propose to assess the effects of 3 lithium dosages for 6 months on the above targets measured in blood in a randomized, parallel design, proof of concept clinical trial among 18 PD patients. In addition, 2 PD patients will serve as controls and not receive lithium therapy.

Influenza A virus (IAV) infection in pregnancy resembles a preeclamptic phenotype characterised by vascular dysfunction and foetal growth retardation. Given that low dose aspirin (ASA) is safe in pregnancy and is used to prevent preeclampsia, we investigated whether ASA or NO-conjugated aspirin, NCX4016, resolve vascular inflammation and function to improve offspring outcomes following IAV infection in pregnant mice. Pregnant mice were intranasally infected with a mouse adapted IAV strain (Hkx31; 104 plaque forming units) and received daily treatments with either 200µg/kg ASA or NCX4016 via oral gavage. Mice were then culled and the maternal lungs and aortas collected for qPCR analysis, and wire myography was performed on aortic rings to assess endothelial and vascular smooth muscle functionality. Pup and placentas were weighed and pup growth rates and survival assessed. IAV infected mice had an impaired endothelial dependent relaxation response to ACh in the aorta, which was prevented by ASA and NCX4016 treatment. ASA and NCX4016 treatment prevented IAV dissemination and inflammation of the aorta as well as improving the pup placental ratios in utero, survival and growth rates at post-natal day 5. Low dose ASA is safe to use during pregnancy for preeclampsia and this study demonstrates that ASA may prove a promising treatment for averting the significant vascular complications associated with influenza infection during pregnancy.
The study arm group will have the ICE catheter placed through one of two existing 8F sheaths already in the left atrium. The ICE catheter will be exchanged in the sheath utilizing the lasso multipolar mapping catheter during left pulmonary vein ablation lines. During exchange, suction and irrigation techniques will be utilized to avoid any air or thrombus embolization. All patients will have standard anticoagulation during the procedure with heparin infusion adjusted to an activated clotting time (ACT) of 350-400. The left sided ICE catheter will be adjusted to visualize left sided structures, ablation tip and tissue interface, and adjacent noncardiac structures such as the esophagus during radiofrequency ablation of the left pulmonary vein system.
Guanfacine is a selective central alpha2A-adrenergic receptor agonist in that it has a 15 to 20 times higher affinity for this receptor subtype than for the alpha2B or alpha2C subtypes.

Guanfacine is a known antihypertensive agent. By stimulating central alpha2A-adrenergic receptors, guanfacine reduces sympathetic nerve impulses from the vasomotor center to the heart and blood vessels. This results in a decrease in peripheral vascular resistance and a reduction in heart rate.

In a thorough QT study, the administration of two dose levels of immediate-release guanfacine (4 mg and 8 mg) produced concentrations approximately 2 to 4 times the concentrations observed with the maximum recommended dose of guanfacine extended-release of 0.12 mg/kg. Guanfacine was not shown to prolong the QTc interval to any clinically relevant extent.
