Survival Analysis and Interpretation of Time-to-Event Data: The Tortoise and the Hare
Survival analysis, or more generally, time-to-event analysis, refers to a set of methods for analyzing the length of time until the occurrence of a well-defined end point of interest. A unique feature of survival data is that typically not all patients experience the event (eg, death) by the end of the observation period, so the actual survival times for some patients are unknown. This phenomenon, referred to as censoring, must be accounted for in the analysis to allow for valid inferences. Moreover, survival times are usually skewed, limiting the usefulness of analysis methods that assume a normal data distribution. As part of the ongoing series in Anesthesia & Analgesia, this tutorial reviews statistical methods for the appropriate analysis of time-to-event data, including nonparametric and semiparametric methods—specifically the Kaplan-Meier estimator, log-rank test, and Cox proportional hazards model. These methods are by far the most commonly used techniques for such data in medical literature. Illustrative examples from studies published in Anesthesia & Analgesia demonstrate how these techniques are used in practice. Full parametric models and models to deal with special circumstances, such as recurrent events models, competing risks models, and frailty models, are briefly discussed.

Physical activity effects on the individual alpha peak frequency of older adults with and without genetic risk factors for Alzheimer’s Disease: A MEG study

Abstract
Objective
Since a cure for Alzheimer's Disease (AD) is yet to be discovered, attention has shifted towards prevention. Physical activity (PA) emerged as a notorious lifestyle factor that could influence brain structure and function. The individual alpha peak frequency (IAPF) is a measure that summarizes the spectral content of brain signals and has been proven to be sensitive to both AD pathology and PA interventions. Therefore, our goal was to unravel whether chronic PA modulates IAPF and if APOE ɛ4 carriage moderates this relationship.
Methods
We analyzed 4-minutes of resting-state magnetoencephalographic recordings from 100 healthy elders that provided self-reported measures of PA, and the IAPF was calculated.
Results
We found that IAPF was negatively influenced by age and APOE and positively influenced by PA. The effect of PA on IAPF only remained significant for the ɛ4 non-carriers group.
Conclusions
PA is positively associated to higher IAPF in healthy older adults and could potentially act as a protective factor against cognitive decline. Nevertheless, such effect is non-significant among elders who are more vulnerable to developing AD due to their genetic carriage.
Significance
This investigation offers the first neurophysiological evidences on the combined effects of APOE genotype and PA in healthy elders.

PhoPepMass: A database and search tool assisting human phosphorylation peptide identification from mass spectrometry data
Publication date: Available online 19 July 2018

Author(s): Menghuan Zhang, Hui Cui, Lanming Chen, Ying Yu, Michael O. Glocker, Lu Xie
Abstract
Protein phosphorylation, one of the most important protein post-translational modifications, is involved in various biological processes, and the identification of phosphorylation peptides (phosphopeptides) and their corresponding phosphorylation sites (phosphosites) will facilitate the understanding of the molecular mechanism and function of phosphorylation. Mass spectrometry (MS) provides a high-throughput technology that enables the identification of large numbers of phosphosites. PhoPepMass is designed to assist human phosphopeptide identification from MS data based on a specific database of phophopeptide masses and a multivariate hypergeometric matching algorithm. It contains 244,915 phosphosites from several public sources. Moreover, the accurate masses of peptides and fragments with phosphosites were calculated. It is the first database that provides a systematic resource for the query of phosphosites on peptides and their corresponding masses. This allows researchers to search certain proteins of which phosphosites have been reported, to browse detailed phosphopeptide and fragment information, to match masses from MS analyses with defined threshold to the corresponding phosphopeptide, and to compare proprietary phosphopeptide discovery results with results from previous studies. Additionally, a database search software is created and a "two-stage search strategy" is suggested to identify phosphopeptides from tandem mass spectra of proteomics data. We expect PhoPepMass to be a useful tool and a source of reference for proteomics researchers. PhoPepMass is available at https://www.scbit.org/phopepmass/index.html.

P66. Long term follow-up in bilateral deep brain stimulation of VIM in MS-related tremor
Tremor in Multiple Sclerosis is an important cause for disability. As medical treatment often does not provide a sufficient reduction of tremor amplitude, deep brain stimulation is an important option in these patients. Because in previous studies often unilateral stimulation of the VIM was performed, the aim of our retrospective analysis was to evaluate the effect of bilateral stimulation on tremor amplitude, activities of daily living, and due to an additional effect on axial tremor, improvement of global disability (EDSS) and mobility.

Association Between Maternal 2nd Trimester Plasma Folate Levels and Infant Bronchiolitis
Abstract
Objectives Viral bronchiolitis is the most common cause of infant hospitalization. Folic acid supplementation is important during the periconceptional period to prevent neural tube defects. An area of investigation is whether higher prenatal folate is a risk factor for childhood respiratory illnesses. We investigated the association between maternal 2nd trimester plasma folate levels and infant bronchiolitis. Methods We conducted a retrospective cohort analysis in a subset of mother-infant dyads (n = 676) enrolled in the Conditions Affecting Neurocognitive Development and Learning in Early Childhood study and Tennessee Medicaid. Maternal folate status was determined using 2nd trimester (16–28 weeks) plasma samples. Bronchiolitis diagnosis in the first year of life was ascertained using International Classification of Diagnosis-9 codes from Medicaid administrative data. We used multivariable logistic regression to assess the adjusted association of prenatal folate levels and infant bronchiolitis outcome. Results Half of the women in this lower-income and predominately African-American (84%) study population had high levels of folate (median 2nd trimester level 19.2 ng/mL) and 21% of infants had at least one bronchiolitis healthcare visit. A relationship initially positive then reversing between maternal plasma folate and infant bronchiolitis was observed that did not reach statistical significance (poverall = .112, pnonlinear effect = .088). Additional adjustment for dietary methyl donor intake did not significantly alter the association. Conclusions for Practice Results did not confirm a statistically significant association between maternal 2nd trimester plasma folate levels and infant bronchiolitis. Further work is needed to investigate the role of folate, particularly higher levels, in association with early childhood respiratory illnesses.

Hypotension after induction of general anesthesia: occurrence, risk factors, and therapy. A prospective multicentre observational study
Abstract
Background
Hypotension after induction of general anesthesia (GAIH) is common in anesthesiology practice and can impact outcomes.
Methods
In this prospective multicenter, cross-sectional, observational study, the hypotension was defined as a decrease in mean arterial pressure of > 30% compared to the first measurement in the operation theatre before general anesthesia (GA) induction. Blood pressure was measured immediately at the time of endotracheal intubation (TETI), at five (T5) and 10 (T10) minutes after. All subjects aged > 18 years undergoing elective non-cardiac surgery under GA were included. The goals were description of GAIH occurrence, the association of GAIH with selected comorbidities, chronic medications, and anesthetics with GAIH, and the type and efficacy of interventions used to correct hypotension.
Results
Data from 661 subjects, whose GA was induced with propofol and sufentanil, were analyzed. In 36.5% of subjects, GAIH was observed at ≥ 1 of the assessed time points. GAIH was present in 2.9% subjects at all time points. The probability of GAIH is raising with age, degree of hypertension at time of arrival to theatre and presence of diabetes. The type of volatile anesthetic was not associated with the occurrence of GAIH. The overall efficiency of interventions to correct hypotension was 94.4%. Bolus fluids were the most often used intervention and was 96.4% effective.
Conclusion
GAIH rate depends on age, degree of blood pressure decompensation prior the surgery, and presence of diabetes mellitus type II.

The evidence for fungus in Crohn’s disease pathogenesis
Abstract
Current evidence suggests the etiology of inflammatory bowel diseases (IBD) involves the confluence of host genetic, environmental, and microbial factors that lead to chronic, and often refractory, disease in susceptible individuals. The involvement of microbial triggers in IBD, including Crohn's disease (CD), is increasingly evident with supporting data provided with advancements in metagenomic sequencing that have identified perturbations in microbial structure and function—broadly termed dysbiosis—in CD patients compared with healthy subjects. This concept is supported by the finding germ-free animals with CD genetic susceptibility fail to develop disease; demonstrating microorganisms are necessary but not sufficient for CD. The vast majority of CD microbiome research has focused on the complex bacterial communities and microbiome dysbiosis in the gut with 16S metagenomic sequencing. However, emerging data capturing eukaryotes suggest fungal opportunistic pathogens are also associated with IBD pathogenesis and chronicity. This hypothesis is further supported by historical observations that CD patient populations display elevated antibodies against fungal targets, even evident before disease diagnosis. This review discusses the current findings in the field, followed by historical and metagenomic evidence for fungal pathogens in the development and recurrence of CD in adult and pediatric populations.

Abstract
Basic airway management in both the pediatric and adult populations includes assessing and managing airway patency, oxygen delivery, and ventilation. All efforts should be taken to maintain a patient's airway via non-invasive methodology unless indications for invasive airway management are apparent. Non-invasive airway supplementation includes passive oxygenation (nasal cannula, non-rebreather, among others), bag-valve-mask (BVM), non-invasive positive pressure ventilation (BVM with positive-pressure valve, CPAP, BIPAP), and supraglottic airways (King Tube, LMA. among others). Invasive airway management involves establishing a secure airway and placing patients on a ventilator via intubation (nasal or endotracheal), needle jet ventilation (in pediatric patients younger than 8 years old, cricothyroidotomy in pediatric patients older than 8 years old, and adults), and tracheostomy. Proper airway management begins by looking at the patient visually for trauma, obesity, cervical collar, macroglossia, among other factors to determine the type of airway approach best suited for each patient. Most important is positioning via the head tilt-chin lift maneuver, which involves extending the patient's neck by putting one hand on the forehead and the other hand on the neck to allow for the extension of the head in relation to the neck. This maneuver puts the patient into sniffing position, with the nose pointed upward and forward. Then a chin lift can be performed by taking the hand from underneath the neck to underneath the chin (mandible) and lifting the mandible until the teeth barely touch. Another airway positioning method involves the jaw thrust maneuver, which is safer in potential cervical spinal cord injury patients. This method involves maintaining the spine in a neutral position and grabbing the sides of the angle of the mandible and lifting it forward to lift the jaw and open the airway. There are some differences between the pediatric and adult populations. For example, the large occiput of the pre-pubescent pediatric patient can lead to too much flexion of the neck and can cause tracheal obstruction. This is addressed by utilizing the head tilt-chin lift maneuver, but care must be taken to avoid overextension in the pediatric population as it can cause airway obstruction due to a weak trachea in the pediatric patient. However, the head tilt-chin lift may not be adequate to maintain a patent airway, and the jaw thrust maneuver may need to be employed to prevent the pediatric, large, floppy tongue from obstructing the airway. Once properly positioned, the rescuer has the best shot at delivering effective breaths either via mouth to mouth or BVM. If there is continued difficulty at delivering breaths, then airway adjuncts like an oral pharyngeal airway (OPA) device or nasopharyngeal airway (NPA) can be useful for maintaining a patent airway to allow delivery of breaths in an unresponsive patient. NPA devices can be useful at maintaining the airway in an awake patient as well, which is beneficial if intubation is not the goal, intubation needs to be delayed, or an awake intubation is necessary. NPA devices are plastic hollow or soft rubber tubes that a healthcare provider can utilize to help with patient oxygenation and ventilation when the patient is difficult to oxygenate or ventilate via BVM, for example. NPAs are passed into the nose and pass through to the posterior pharynx. NPAs do not cause patients to gag and are, therefore, the best airway adjunct route in an awake patient and the better choice in a semiconscious patient that may not tolerate an OPA due to the gag reflex. NPAs are also helpful when a patient's mouth is difficult to open, for example, if there are angioedema, trismus, or other factors. While NPAs are airway adjuncts for difficult patient ventilation and oxygenation, they only act as a bridge to either an eventually stabilized patient that is breathing without aid or a patient that requires a secure airway via endotracheal or nasotracheal (NT) intubation. The NT route for intubation was the preferred route among critical care and emergency physicians up until several decades ago. However, today, the majority of clinicians prefer the endotracheal route for intubation as it has been shown to have better results and fewer complications. Some of the complications of NT intubation include sinusitis, nasal structure destruction due to localized pressure and decreased perfusion of nasal cartilage, and local abscesses. Furthermore, NT intubation requires narrow tubes making pulmonary toilet very difficult due to the increased airway resistance. However, there are clear advantages to NT intubation. NT intubation can be performed in the sitting position, which is valuable, especially in the pre-hospital setting when needing to intubate a patient in acutely decompensated heart failure that cannot lay flat. Other advantages include the patient's inability to bite or manipulate the tube, better patient tolerance, decrease salivation, and better access to patient oral care. In addition, the NT tube is much more stable as it has the entire nasal tract holding it in place versus the endotracheal tube that flops out the mouth and can easily dislodge or become right mainstemmed. NT intubation can be performed blind or with a flexible bronchoscope. Blind NT intubation is difficult and requires expertise and skill. However, when indicated, can be a very useful skill both in the prehospital and hospital setting. Blind NT intubation decreases the need for neck movement and mouth opening, but can only be done in the awake and ventilating patient. NT intubation via a flexible bronchoscope also requires lots of expertise and skill, and it is useless if there is blood, vomitus, or fluid that will obscure the bronchoscopes camera.

Background and Aims
Gastric volvulus (GV) is a life-threatening condition that warrants prompt diagnosis and treatment. GV is a radiologic diagnosis. The role of preoperative upper gastrointestinal endoscopy (UGIE) for individuals with radiologically confirmed GV is poorly defined. Our objective was to assess the diagnostic yield of UGIE in the preoperative evaluation of patients presenting with radiologically confirmed GV.
Methods
Retrospective review of all adult patients undergoing surgery for GV between July 1996 and August 2016 has been carried out. We performed analyses evaluating diagnostic yield of preoperative UGIE and compared outcomes in patients who did and did not undergo preoperative UGIE. Outcomes were diagnostic yield of preoperative UGIE, length of hospital stay, postoperative complications, and mortality at 30 days and 1 year.
Results
In the preoperative UGIE group, the diagnostic yield was 34.6% (27/78). The most common endoscopic findings were erosive esophagitis (13/27) and clean based gastric or duodenal ulcers (5/27). There were no cases of esophago-gastric malignancy. Three patients had ulcers with stigmata of recent bleeding, and three patients had features suggestive of gastric ischemia. Endoscopic findings did not influence surgical management. There was no statistically significant difference in mortality between patients who did and did not undergo preoperative UGIE, both at 30 days (0 vs. 2.5%) and 1 year (3.8 vs. 7.5%).
Conclusion
Among patients with radiologically confirmed GV, preoperative UGIE rarely demonstrates clinically significant findings and can potentially delay definitive surgical intervention.

Abstract
Maize (Zea mays) is the most widely grown grain crop in the world, playing important roles in agriculture and industry. However, the functions of maize genes remain largely unknown. High-quality genome-wide transcriptome datasets provide important biological knowledge which has been widely and successfully used in plants not only by measuring gene expression levels but also by enabling co-expression analysis for predicting gene functions and modules related to agronomic traits. Recently, thousands of maize transcriptomic data are available across different inbred lines, development stages, tissues, and treatments, or even across different tissue sections and cell lines. Here, we integrated 701 transcriptomic and 108 epigenomic data and studied the different conditional networks with multi-dimensional omics levels. We constructed a searchable, integrative, one-stop online platform, the maize conditional co-expression network (MCENet). Besides 10 global/conditional co-expression networks, MCENet provides five network accessional analysis toolkits (i.e., Network Search, Network Remodel, Module Finder, Network Comparison, and Dynamic Expression View) and multiple network functional support toolkits (e.g., motif and module enrichment analysis). We hope that our database might help plant research communities to identify maize functional genes or modules that regulate important agronomic traits. MCENet is publicly accessible at http://bioinformatics.cau.edu.cn/MCENet/.

Correction to: Effects of Intrahippocampal Injections of Melipramin on EEG, Brain Self-Stimulation, and Behavioral Indices of Rats under Conditions of Neurogenic Stress
There are mistakes in the designations for Fig. 1 (the order of indications of the EEG ranges above the columns should be changed from α, β, and θ to α, θ, and β) and in Fig. 7 (an asterisk above the third column in panel F should be moved to the second column).
