Data collection will be performed retrospectively utilizing the electronic medical record system at each participating institution. All data collection will be performed using REDCap, a secure web-based data collection tool that meets the HIPAA (Health Insurance Portability and Accountability Act of 1996) requirements for protection of patient health information. Data collected will include various site and patient demographic data. The investigators will also collect opioid and sedative doses, durations of therapy, weaning of doses, and withdrawal assessments.
The following information and instructions should be given to patients receiving barbiturates.

  1. The use of barbiturates carries with it an associated risk of psychological and/or physical dependence. The patient should be warned against increasing the dose of the drug without consulting a physician. 
  2. Barbiturates may impair the mental and/or physical abilities required for the performance of potentially hazardous tasks, such as driving a car or operating machinery. The patient should be cautioned accordingly. 
  3. Alcohol should not be consumed while taking barbiturates. The concurrent use of the barbiturates with other CNS depressants (e.g., alcohol, narcotics, tranquilizers, and antihistamines) may result in additional CNS-depressant effects.

The functionality of the central nervous system (CNS) relies on the connection, integration, and the exchange of information among neural cells. The crosstalk among glial cells and neurons is pivotal for a series of neural functions, such as development of the nervous system, electric conduction, synaptic transmission, neural circuit establishment, and brain homeostasis. Glial cells are crucial players in the maintenance of brain functionality in physiological and disease conditions. Neuroinflammation is a common pathological process in various brain disorders, such as neurodegenerative diseases, and infections. Glial cells, including astrocytes, microglia, and oligodendrocytes, are the main mediators of neuroinflammation, as they can sense and respond to brain insults by releasing pro-inflammatory or anti-inflammatory factors. Recent evidence indicates that extracellular vesicles (EVs) are pivotal players in the intercellular communication that underlies physiological and pathological processes. In particular, glia-derived EVs play relevant roles in modulating neuroinflammation, either by promoting or inhibiting the activation of glial cells and neurons, or by facilitating the clearance or propagation of pathogenic proteins. The involvement of EVs in neurodegenerative diseases such as Alzheimer's Disease (AD), Parkinson's Disease (PD), Huntington's Disease (HD), and Multiple Sclerosis (MS)- which share hallmarks such as neuroinflammation and oxidative stress to DNA damage, alterations in neurotrophin levels, mitochondrial impairment, and altered protein dynamics- will be dissected, showing how EVs act as pivotal cell-cell mediators of toxic stimuli, thereby propagating degeneration and cell death signaling. Thus, this review focuses on the EVs secreted by microglia, astrocytes, oligodendrocytes and in neuroinflammatory conditions, emphasizing on their effects on neurons and on central nervous system functions, considering both their beneficial and detrimental effects.
The HuTT® program emphasizes proper tackling and blocking techniques using a progressive series of closely supervised drills. Skill rehearsal is done without helmets and shoulder pads and is the inherent element of HuTT® in order to reinforce behaviors which remove the head as a point of contact. The HuTT® program is modeled after basic tackling/blocking drills familiar to the sport of football. Feedback to confirm or correct proper skill development is provided by coaches trained in the HuTT® technique. HuTT® drills are conducted at an intensity of 50-75% effort and over a period of approximately 10 minutes. The intervention will be conducted 2 times each week throughout the regular season.
OBJECTIVE: Seizure care is a significant driver of health care costs in both emergency department (ED) and inpatient settings, but the majority of studies have focused on inpatient admissions as the only metric of health care utilization. This study aims to better characterize ED and inpatient encounters among patients with seizure to inform care and policy.
METHODS: Using statewide administrative data from the Healthcare Cost and Utilization Project State Inpatient Databases and State Emergency Department Databases from Florida and New York, we identified patients with a seizure-related index hospitalization between January 1, 2016, and December 31, 2018. Among this cohort, we examined the incidence and characteristics of subsequent acute care visits in the ED and inpatient settings for 365 days after initial hospital discharge.
RESULTS: A total of 54 456 patients had an eligible seizure-related hospitalization. Patients were 49% female, predominantly White (64%) and non-Hispanic (84%), and used a public primary payer (68%). There were 36 838 (68%) patients with at least one acute care visit in the year following discharge. Overall, patients had a median of 2 (interquartile [IQR] = 1-5) subsequent acute care visits and the median time to first acute care visit was 53 days (IQR = 15-138). Of the 154 369 subsequent acute care visits, 97 399 (63%) were ED-only visits, 56 970 (37%) were readmissions, and 37 176 (24%) were seizure-related. There were 18 786 patients (35%) with four or more acute care visits over 365 days of follow-up. Patients with four or more visits contributed 84% of acute care visits and 78% of costs after initial hospitalization.
SIGNIFICANCE: The majority of patients hospitalized for seizure return to the ED or hospital at least once in the year after discharge. A small portion of patients account for the majority of ED and inpatient visits as well as health care costs associated with this population, identifying a subgroup of patients who may benefit from improved inpatient and outpatient management.
BACKGROUND: This study aimed to investigate the regulatory mechanism of the adipose factor interleukin (IL)-6 in promoting pentraxin 3 (PTX3) expression in triple-negative breast cancer (TNBC).
METHODS: We established an in vitro coculture model of mature adipocytes and TNBC cells using a Transwell system. Cell scratch, Transwell migration, and matrix invasion assays were used to evaluate the migration and invasion abilities of TNBC cells cocultured with adipocytes. Next, we used lentivirus-mediated functional depletion experiments to study PTX3's role in the adipocyte-dependent migration of TNBC cells.
RESULTS: After coculturing TNBC cells with adipocytes, PTX3 expression was upregulated, which accompanied enhanced cell migration and invasion. Using GEO data and RNA-seq analysis, we identified PTX3 as a key target gene influenced by the adipose TNBC microenvironment. IL-6 upregulation in the conditioned medium of mature adipocytes and in the serum of high-fat diet mice was associated with this effect, and the recombinant protein IL-6 significantly promoted the migration and invasion of TNBC cells along with the phosphorylation of intracellular STAT3 and the upregulation of PTX3. PTX3 knockdown inhibited TNBC cell migration and eliminated the enhanced migration caused by coculturing with adipocytes. Furthermore, in vivo experiments confirmed that the PTX3 knockdown reduced obesity-induced lung metastasis. Subsequent experiments with cytokines and drug inhibitors confirmed that adipocyte-derived IL-6 promoted PTX3 expression by activating the STAT3 signaling pathway. Additionally, bioinformatic analysis indicated that PTX3 promotes TNBC metastasis by regulating the matrix metalloproteinase (MMP) family.
CONCLUSION: Our study elucidated Obesity-related metabolic inflammation promotes the progression via the IL-6/STAT3/PTX3/MMP7 axis.
Sleep-related breathing disorders (obstructive and central) are highly prevalent in Heart failure (HF) patients and are associated with an increase in morbidity and mortality. Nocturnal oxygen therapy (NOT) reduces the frequency of central breathing events by 75 % and prevents nocturnal desaturation in patients with HF. Considering that the amount of nocturnal desaturation is a better predictor of mortality than the apnea+hypopnea index (AHI) in this population, one should expect NOT to have a positive impact on survival in these patients. In the four randomized clinical trials where the effects of O2 on left ventricular function was assessed, 2 reported a significant increase in LVEF after 3 months of NOT. NOT was also found to positively impact on other important predictive factors of mortality such as sympathetic activity and VO2 max. These mitigated results could be accounted by the fact that a fixed O2 flow was empirically used (2 to 4 L/min) in the majority of studies. This may impede the beneficial effects of NOT for two reasons. First, in patients with HF, oxygen is associated with a dose-related detrimental hemodynamic effects (i.e. increase in vascular resistance and reduction in cardiac output and stroke volume). Therefore, the lowest O2 flow that prevents nocturnal desaturation should be used to minimize the detrimental effects of hyperoxia. On the other hand, there are evidences that the frequency and/or severity of sleep-disordered breathing may change overtime in CHF patients leading to insufficient correction of nocturnal desaturation during the course of NOT. Therefore, NOT should be preceded by an oxygen titration procedure to determine the lowest O2 flow that prevents nocturnal desaturation. This can be done with a stepwise night-to-night increase in O2 flow until correction of nocturnal desaturation. However, another approach would be to prevent event-by-event desaturations and to prevent hyperoxia during periods of normal sleep and wakefulness. On the other hand, the stability in O2 needs overtime in these patients is unkown. The aims of this study are 1) to document if the level of O2 flow preventing nocturnal desaturation changes during the course of NOT in CHF patients with CSA/CSR and 2) to examine the ability of automated O2 titration (FreeO2, Oxynov, Quebec, Canada) to determine O2 needs in HF patients with CSA/CSR when compared to the gold standard titration procedure.

After initial evaluation, the subjects will be instructed to perform deep breaths between three quiet inspiration brought, and expiration will be accompanied by bilateral compression with the therapist's hands on the lower ribs during thirty minutes with one minute intervals of rest every four minutes. Immediately after the exercise will be performed new assessment against Impulse Oscillometry. Then patients will be kept for 30 minutes at rest and at the end will be applied the acceptability and tolerance scale and a third evaluation with Impulse Oscillometry. The secretions expectorated during the protocol will be evaluated for weight, adhesiveness and purulence.
A biosensor for detection of vascular endothelial growth factor (VEGF) hybridization uses an array of parallel capacitors to detect electrochemical binding of circulating VEGF to immobilized anti-VEGF monoclonal half-antibodies (a-VEGF mhAb). Binding of a-VEGF mhAb modulates the threshold voltage of a circuit, changing the impedance of the circuit. An electrode coated with a p-Si substrate enhances the affinity between the VEGF molecules. A fluid cell delivers VEGF samples onto the active surface of the chip. An array of parallel capacitors arranged in an interdigitated pattern detects the VEGF in the fluid. The detector provides an accurately measured and quantifiable rate of change of the VEGF molecules in vivo, providing real time feedback which is used to measure response of the tumor to delivered chemotherapeutic agents and biological response modifiers (BRMs) for the purpose of determining tumor burden and efficacy of the chemotherapy as part of a homeostatic loop for chemotherapy.
Hereditary Sensory Neuropathy (HSN) represents a subgroup of disorders called Charcot Marie Tooth (CMT) disease. Hereditary Sensory Neuropathy Type 1 (HSN1) is the most common subtype. It is a rare autosomal dominant (AD) neuropathy characterised by severe sensory and motor involvement for which there is no current treatment. HSN1 secondary to SPTLC1/2 mutations is the commonest type of HSN. The neuropathy is slowly progressive with onset between the second and fifth decade. The profound sensory involvement is associated with painless ulcers, recurrent osteomyelitis, and amputations. The neuropathy is very painful and pain medications are rarely fully efficacious. Motor involvement invariably follows leading to significant disability. HSN1 is due to mutations in the SPTLC1 and more rarely SPTLC2 genes which encode for the first two (out of 3) subunits of the enzyme serine palmitoyl transferase (SPT) which catalyses the first and rate limiting step in de novo sphingolipid biosynthesis. Mutations in SPTLC1 and SPTLC2 cause the neuropathy by a gain of function mechanism as mutations alter the substrate specificity of SPT whereby alanine and glycine are preferred over the canonical serine resulting in the production of neurotoxic deoxysphingolipids (DSBs).

This single-site double-blinded placebo-controlled trial will investigate whether L-serine is efficacious in the treatment of HSN1 due to SPTLC1/2 mutations.

The primary objective is to identify if treatment with L-serine is efficacious in the treatment of HSN1 due to SPTLC1/2 mutations compared to treatment with placebo. A major objective will be to validate the use of the MRC Muscle Fat Fraction protocol as a primary outcome measure in inherited neuropathies trials. The MRC Muscle Fat Fraction protocol has been shown to be a responsive biomarker in natural history studies in several inherited neuropathies including HSN, but not previously in clinical trials. Regardless of the efficacy outcome, the trial will assess the feasibility of MRI as an outcome measure in a clinical trial setting, and comparison of the results in the placebo arm to previous natural history study data will validate the translation of natural history results to the clinical trial setting.
The immunoprotective components control COVID-19 disease severity, as well as long-term adaptive immunity maintenance and subsequent reinfection risk discrepancies across initial COVID-19 severity, remain unclarified. Here, we longitudinally analyzed SARS-CoV-2-specific immune effectors during the acute infection and convalescent phases of 165 patients with COVID-19 categorized by severity. We found that early and robust SARS-CoV-2-specific CD4+ and CD8+ T cell responses ameliorate disease progression and shortened hospital stay, while delayed and attenuated virus-specific CD8+ T cell responses are prominent severe COVID-19 features. Delayed antiviral antibody generation rather than titer level associates with severe outcomes. Conversely, initial COVID-19 severity imprints the long-term maintenance of SARS-CoV-2-specific adaptive immunity, demonstrating that severe convalescents exhibited more sustained virus-specific antibodies and memory T cell responses compared to mild/moderate counterparts. Moreover, initial COVID-19 severity inversely correlates with SARS-CoV-2 reinfection risk. Overall, our study unravels the complicated interaction between temporal characteristics of virus-specific T cell responses and COVID-19 severity to guide future SARS-CoV-2 wave management.
Brain metastases (BM) from colorectal cancer (CRC) are a rare event reported in less than 3% of patients with CRC (the reported incidence ranges from 0.27 to 3%). This course is associated with a poor prognosis. Treatment of these patients remains challenging. Nevertheless, given the rarity of the event, at this time not enough is known about molecular biology of BM from colorectal cancer and its concordance with matched primary tumors.

In N.N. Blokhin National Medical Research Center of Oncology over 26 years (1998-2024) identified 108 patients with BM from CRC. Of this number, 72 patients had a history of neurosurgical resection of BM. In turn, for 32 patients access to a pair of tumor samples: from the primary tumor and from intracranial metastases. Tumor samples will be tested for mutation status of genes KRAS, NRAS, BRAF, HER2 and MSI. Analysis was limited to this pool of genes because of their clinical relevance and potential prognostic information. The molecular profile of the BM will be compared with the corresponding primary tumor with calculation of concordance rate (%).
BACKGROUND: Peritonitis is the leading cause of peritoneal dialysis (PD) discontinuation. However, few data concern risk factors of peritonitis development and catheter removal caused by treatment failure in pediatric patients.
METHODS: This single-center, retrospective study analyzed data from pediatric patients who underwent chronic PD between March 2002 and June 2022. The incidence rates of peritonitis by the person-year method were calculated, and they were stratified by patient age groups. Risk factors for peritonitis development and catheter removal were also analyzed by multivariate analysis using logistic regression model.
RESULTS: Ninety patients were enrolled, and 62 peritonitis episodes were observed in 41 (46%) patients. The incidence rate of peritonitis was 0.21 episodes per patient-year, which was the highest in children aged under 2 years old (0.26 episodes per patient-year). Moreover, 44 (71%) cases were successfully cured by antibiotics alone, although 17 (27%) cases required catheter removal, and 4 (6%) cases transitioned to chronic hemodialysis because of peritoneal dysfunction. One patient died. The risk factor for peritonitis development and catheter removal caused by treatment failure was PD insertion at under 2 years old (odds ratio = 2.5; P = 0.04) and Pseudomonas aeruginosa (odds ratio = 11.0; P = 0.04) in the multivariate analysis. P. aeruginosa was also a risk factor for difficulty in re-initiating PD (P = 0.004).
CONCLUSIONS: The incidence rate of peritonitis was the highest in children under 2 years old. P. aeruginosa peritonitis is a risk factor for catheter removal and peritoneal dysfunction.
