tation to avoid floor effects.
DBS treatment is associated with reduced epilepsy severity and disability in young adults with LGS. Performing cognitive and behavioral outcome measurement in patients with cognitive impairment is challenging but possible and requires careful selection of instruments and modifications of score interpretation to avoid floor effects.Analytical procedure for detection and quantification of etaqualone in human blood and urine using GC-MS/MS was established and applied to authentic human samples obtained from volunteers. A liquid-liquid extraction method was employed. Each 1.0 mL of blood or urine was alkalized and extracted with diethyl ether. The solvent layer was evaporated to dryness and reconstituted with methanol then analyzed by GC-MS/MS. linear relationships within the concentration range of 1-100 ng/mL were obtained in calibrators for both blood and urine, demonstrating correlation coefficients values being>0.999. For blood and urine samples, the intra-day assay precision and accuracy values are each less than 3.65%, 7.13%, and 6.02%, 9.12%; those values of the inter-day assay are each less than 1.82%, 6.74%, and 3.99%, 7.41%. The extraction recovery rates for etaqualone ranged from 98.7% to 106%. The lower limit of quantifications was 1.0 ng/mL in both blood and urine. Stabilities of etaqualone in blood and urine were satisfactory under various temperatures within 15 days. 8.51 and 2.06 ng/mL of etaqualone in blood and urine were detected at 4 h later oral ingestion; 6.91 and 3.94 ng/mL of etaqualone were also detected 30 min and 2 h later smoking from blood and urine.
One goal of research into major depressive disorder (MDD) is to develop markers to predict and monitor the response to psychotropic treatments. The retina is endowed with a complex neurotransmission system, composed of the main neurotransmitters involved in the pathophysiology of MDD. The retina is therefore a relevant site of investigation for the identification of reliable and robust markers. However, the effects of antidepressants on the human retina are poorly studied. Here, we seek to study the potential specific effects of various antidepressants on retinal function in MDD patients.

We assessed retinal function using flash (fERG), pattern (PERG) and multifocal (mfERG) electroretinogram in 19 MDD patients treated using antidepressants at baseline and at weeks 4, 8 and 12.

We observed reduced b-wave amplitude of photopic fERG 3.0 in patients treated with Selective Serotonin Reuptake Inhibitor (SSRI) in comparison with patients treated with Serotonin-Norepinephrine Reuptake Inhibitor (SNRI) or Tricyclic Antidepressant (TCAD). We also showed that SNRIs were associated both with a decrease in PERG P50 implicit time and an increase in fERG 3.0b-wave amplitude. TCADs were associated with an increase in fERG flicker 3.0 a- and b-wave amplitude.

This is the first study in real-life conditions to show a specific effect of various antidepressants on retinal function evaluated by electroretinogram. Further investigations should be led to specify the effects of antidepressants on ERG in order to isolate reliable and reproducible markers for predicting and monitoring the response to antidepressants.

Childhood trauma (CT) has been supported to be a high-risk factor for major depressive disorder (MDD), but the neural mechanism linking CT and depression remains unclear. The aim of this study is to deepen our understanding of this issue by establishing the neuroimaging correlations between CT and depression.

A sample of 123 MDD patients (91 with moderate-to-severe CT and 32 with no or low CT) and 79 healthy controls (HC, 33 with moderate-to-severe CT and 46 with no or low CT) participated. All participants completed assessments of depression level, anxiety, recent perceived stress, and resting-state functional MRI scan.

Participants with moderate-to-severe CT showed elevated depression level and trait anxiety, and reduced spontaneous neural activity in left inferior temporal gyrus (ITG). Abnormalities of seed-based functional connectivity (FC) of left ITG - bilateral precuneus/posterior cingulate cortex (PCC), left middle temporal gyrus (MTG), left medial orbitofrontal cortex (mOFC), and bilateral medial prefrontal cortex (mPFC)/anterior cingulate cortex (ACC) were observed. CT was associated with decreased FCs in MDD, but with increased FCs in HC. The total altered FCs of left ITG - bilateral precuneus/PCC and left mOFC mediated relationship between CT and depression in MDD, and total altered FCs and trait anxiety have a significant chain mediation effect in the association between CT and depression in HC.

These findings highlight the changes of default mode network (DMN) functions and trait anxiety as targets of CT. The decreased functional coupling within DMN may be involved in the mechanism of MDD following CT.

However, monitoring the peripartum mare is a time-consuming challenge for breeders and many foaling prediction systems have limitations. "Heating up" of the mare is empirically used by breeders as a sign of upcoming parturition in mares. The purpose of this study was to investigate if an increase in skin temperature shortly before parturition is detectable and to determine whether such physiological changes could be an additional valuable parameter to predict foaling. For that, 56 foalings of 14 Warmblood mares, 5 Arabian mares, 27 Thoroughbred mares, and 2 mares of other breeds were analyzed in this 2-year-study. Eight mares were monitored in both years. Mares were between 4 and 22 years old (average 10 ± 5.5 years) and the mean pregnancy length was 342 days (±9 days), resulting in 14 births from primiparous mares and 42 multiparous mares. For monitoring the periparturient mares, the Piavet® system (ease in skin temperature in most mares within 90 min before birth. Using new biomechanical and digital technologies, this finding could generate an additional potential parameter for the detection of impending parturition. However, skin temperature cannot be used as the only predictive diagnostic of impending parturition in the absence of other parameters.
To determine whether radiographic measures of tumor aggressiveness differ by smoking status.

All patients diagnosed with non-small-cell lung cancer(NSCLC)≤30mm in maximum diameter, without clinical evidence of metastasis who had both pre-treatment PET scans and two CT scans at least 90days apart in a prospective cohort, the Initiative for Early Lung Cancer Research on Treatment(IELCART) at Mount Sinai between 2016 and 2020 were identified. Comparison of two measures of tumor aggressiveness, positron emission tomography(PET) SUVmax and tumor volume doubling time(VDT) by smoking status was performed.

Of 417 patients identified, 158 patients had pre-treatment PET scans and at least two CT scans available. The two measures of tumor aggressiveness, SUVmax and VDT values were significantly different between patients who had never smoked and those who smoked patients who never smoked had lower median SUVmax[2.5(IQR 1.1-4.8) vs. 4.2(IQR2.1-9.2),p=0.002] and longer median VDT[(372.6days vs. 225.6days,p=0.001)] compared to those who smoked. Using multivariable analyses, when adjusting for age and sex alone, SUVmax(p=0.004) and VDT(p=0.0001) remained significantly different by smoking status. The final multivariable analysis, adjusted for all three co-variates(sex, age and tumor histology) showed no significant difference in SUVmax and VDT by smoking status [SUVmax(p=0.25) and VDT(p=0.06)].

Smoking history does not influence VDT or PET SUVmax measures of lung cancer aggressiveness.

Approximately 15% of stage I lung adenocarcinomas will recur despite adequate surgical therapy. Adjuvant therapy may benefit specific high-risk subsets; however, it is unclear which patients are sufficiently predisposed to recurrence to warrant intensified therapy.

517 AJCC 8th edition stage I/0 lung adenocarcinomas≤4cm total size were graded (WHO-2015 and WHO-2021) and compared to stage subgroupings using 7-year recurrence free (RFS), disease specific (DSS), and overall survival (OS). Low malignant potential (LMP) adenocarcinoma was assigned as previously defined. Univariate/multivariate analysis was performed to assess risk factors associated with aggressive behavior.

Vascular invasion was the most significant histologic feature on multivariate analysis for both RFS (HR=4.68, p<0.001) and DSS (HR=3.67, p=0.001) and nearly reached significance for OS (HR=1.47, p=0.060). Angioinvasive adenocarcinomas comprised 26% of the cohort and exhibited a 7-year 64% RFS, 73% DSS, and 50% OS; in contrast to 20% WHO-2015-G3 (7-year 71% RFS, 79% DSS, & 54% OS), 44% WHO-2021-G3 (7-year 79% RFS, 85% DSS, & 56% OS), and 21% stage IB (7-year 72% RFS, 79% DSS, and 50% OS) adenocarcinomas. The majority (>50%) of overall mortality was disease specific for angioinvasive adenocarcinoma whereas ≤25% of overall mortality was disease specific for the remaining tumors. Angioinvasive adenocarcinomas were proportionally more common among those still smoking at diagnosis (49%), male sex (49%), and black race (16%) than other subtypes.

Patients with AJCC 8th ed. stage I angioinvasive lung adenocarcinomas are at high-risk of cancer-specific mortality and should be considered for clinical trials evaluating benefit of adjuvant therapy.

ABT-888 mw The species Loxosceles laeta is ubiquitously present in Peru and is responsible for severe accidents in this country. To further characterize L. laeta venom components and to unveil possible variations in the Peruvian population, we provide an overview of the toxins-related transcripts present in the venom gland of Peruvian L. laeta. A dataset from a cDNA library previously sequenced by MiSeq sequencer (Illumina) was re-analyzed and the obtained data was compared with available sequences from Loxosceles toxins. Phospholipase-D represent the majority (69,28 %) of the transcripts related to venom toxins, followed by metalloproteases (20,72 %), sicaritoxins (6,03 %), serine-proteases (2,28 %), hyaluronidases (1,80 %) and Translationally Controlled Tumor Protein (TCTP) (0,56 %). New sequences of phospholipases D,sicaritoxins, hyaluronidase, TCTP and serine proteinases were described. Differences between the here-described toxin sequences and others, previously identified in venom glands from other spiders, were visualized upon sequence alignments.
