0 per 100,000, and in the United States they represent only 0.4% of total cancers (65). The different types of primary small intestinal tumors include adenocarcinomas, carcinoid tumors, lymphomas and sarcomas (66,67).

Adenocarcinoma of the small intestine Adenocarcinoma of the small intestine is the most common type of primary malignancy in the small bowel, and generally presents in older males with a higher incidence Inhibitors,research,lifescience,medical in African Americans than Caucasians. Most cases are sporadic but reported risk factors include sporadic adenomatous polyps, familial adenomatous polyposis and Crohn’s disease. Presentation may include obstruction, jaundice, GI bleeding and abdominal pain, and often presents at an advanced stage. The most common locations for adenocarcinoma are the duodenum and proximal jejunum. Adenocarcinomas may present as polypoid, infiltrative or constricting lesions, with tumors in the duodenal and ampullary regions generally being Inhibitors,research,lifescience,medical exophytic in nature (67). Histologically, these tumors are similar to colorectal adenocarcinomas and are characterized by the degree of pleomorphism, complex glandular architecture, luminal necrosis and invasion. Small intestinal adenocarcinomas are CK7+ in more than half of all cases (Figure 5A), unlike normal small intestinal mucosa which is CK7- and colorectal adenocarcinomas which are CK7-/CK20+ (68). Adenocarcinomas of the small bowel are also positive for

CK20 (Figure 5B), Inhibitors,research,lifescience,medical CDX-2 (Figure 5C), and villin (68). Figure 5 Immunohistochemical Inhibitors,research,lifescience,medical features of small intestinal adenocarcinoma. A. CK7 positivity; B. CK20; C. CDX-2showing diffuse positivity Adenocarcinoma of ampulla of Vater Adenocarcinoma of ampulla of Vater http://www.selleckchem.com/products/Adriamycin.html comprise about 5-6% of cancers arising (69) in the head of the pancreas. These tumors cause obstruction of the bile duct even at a very small size and hence patients often present early in the disease course with jaundice. Two major histologic types have been described:

an intestinal type, arising from the overlying intestinal mucosa of the papilla (intestinal type adenocarcinoma of duodenal papillary origin) and a pancreatobiliary type, derived Inhibitors,research,lifescience,medical from the ductal epithelium which penetrates the duodenal muscularis propria (ampullary carcinoma of pancreatobiliary origin) (69). The intestinal type adenocarcinoma is much more common and has a much better prognosis (70), hence it is important to differentiate these two entities. Fortunately, the immunophenotype of these two types differ, with PD184352 (CI-1040) the intestinal type adenocarcinoma of duodenal papillary origin being positive for CK7, CK20, MUC2 and CDX-2 but negative for MUC1, MUC5AC and CK17; whereas ampullary carcinoma of pancreatobiliary origin is positive for MUC1, CK7, and CK17 but negative for MUC2 (69,70). Gastrointestinal neuroendocrine tumors Gastrointestinal neuroendocrine tumors are tumor derived from endocrine cells and can arise anywhere in the gastrointestinal tract.

Role of funding source. The study was designed by scientists from Merck & Co., Inc, with substantial input from PATH staff and site investigators. Investigators and their institutions were funded by PATH’s Rotavirus Vaccine Program, under a grant from the GAVI Alliance. Merck was involved in all stages of the study. PATH staff independently monitored study execution at sites and participated in pharmacovigilence, data analysis and meetings of the Data Safety Monitoring Board (DSMB). All authors had full access to the data. The corresponding author had final responsibility for

the decision to submit for publication. IWR-1 nmr Study inhibitors subjects (n = 7679) were screened and 7504 (98%) subjects were randomized (3751 PRV: 3753 placebo) with 3348 (89.2%) PRV recipients and 3326 (88.6%) placebo recipients eligible for the per-protocol efficacy analyses ( Fig. 1). Exclusions from the per-protocol efficacy analyses were due to subjects incorrectly receiving vaccine or placebo (3 PRV:1 placebo), less than 3 doses (129 PRV:134 placebo),

laboratory-confirmed natural rotavirus infection before 14 days after the third dose CCI 779 (12 PRV: 16 placebo) incomplete clinical data (255 PRV: 268 placebo), and lost to follow up (4 PRV: 8 placebo). The median follow-up time starting 14 days post-dose three for the analyses was 523 days in the vaccine group and 524 in the placebo group. Efficacy against RVGE. The point estimates for efficacy against RVGE increased with increasing severity of gastroenteritis episodes ( Table 1). The

efficacy against very severe RVGE (Vesikari score, ≥15) was 67.1%, 95% CI (37.0, 83.9) during the first year of life, 33.8% 95% CI (−15.7, 62.8) during the second year of life and 51.2% 95% CI (26.3, 68.2) during the total follow-up period (nearly two years of observation). There were too few cases with higher scores (≥19), as measured by the VCSS, to make it possible to evaluate higher degrees of severity. Efficacy against all-cause GE. The efficacy of the pentavalent rotavirus vaccine against all-cause severe GE (Vesikari score, ≥11) during the first year of life was 23.0%, 95% CI (5.4,37.3) and 15.3%, 95% CI (1.7, Thymidine kinase 27.1) over the course of the study ( Table 2). For all-cause very severe GE (Vesikari score >15), the point estimate for efficacy during the first year of life was 35.9%; 95% CI (5.4,57.0) and was 27.4%, 95% CI (2.7, 46.0) for the total follow-up period: Given a point estimate of 58.9% for efficacy against severe RVGE, an efficacy of 23% for all-cause severe GE, 39% of severe GE during the first year of life was caused by rotavirus at the five sites. For very severe GE, applying the same equation (with a point estimate of 67.1% for efficacy against very severe RVGE) suggests that 53.

2,3 Therefore, children with depression may be experiencing a first episode bipolar depression. Geller et al report 20% to 49% of children with MDD experience a full manic episode by adulthood.45 A positive family history of BD would seem to further elevate the risk of future mania in a depressed

child; however, the exact risk in these children is not known. Given that many if not most of these children will not ever experience mania, careful diagnosis and biological markers for predication would be essential. Unfortunately, at this time there are Inhibitors,research,lifescience,medical no clear biological markers that do predict such likelihood, despite recent advances in neuroimaging and genetics research. In the future, markers such as decreased amygdalar volume, increased limbic activity, and the short allele of the Inhibitors,research,lifescience,medical serotonin transporter gene, may all be combined to calculate relative risk of BD development.46 Until then we are left to rely on careful clinical assessment and family history. Proposed clinical clues of first episode bipolar depression include an acute onset, psychosis, prominent irritability and labile mood, and poor or brief hypomanic reactions to antidepressants.47 Inhibitors,research,lifescience,medical Furthermore, features of atypical depression, including hypersomnia, hyperphagia, and other neurovegetative symptoms, may indicate risk for future manic episodes.48 Despite the uncertainty of actual BD risk, early interventions Inhibitors,research,lifescience,medical in youth with depression

and family histories of BD are beginning to be studied. Geller and colleagues performed the first such study49 in 30 Ceritinib in vitro prepubertal children, all with M.DD and family histories of mood disorder. Forty percent had a parent with BD, 40% had a more distant relative with BD, and 20% had a family history of unipolar depression only. Subjects were randomized to lithium or placebo, and after 6 weeks no differences were found between the two groups in improvement in depressive symptoms. The final Clinical Global Assessment of Severity scores in both groups did improve from baseline, but remained below 60, indicating continuing clinical problems. As there

was a significant Inhibitors,research,lifescience,medical distribution of subjects who responded well and subjects who responded poorly, some subjects may have had second unique factors associated with response, but whether family history was a factor is unknown. Nonetheless, lithium may have limited efficacy in youth with depression at high risk for BD. In another early intervention study, Chang and colleagues investigated the effectiveness of open divalproex in 24 bipolar offspring with mood and/or disruptive behavioral disorders.50 None of the subjects, aged 7 to 17, had bipolar I or II disorder, but all had at least some mild affective symptoms as manifested by a minimum score of 12 on the Young Mania Rating Scale (YMRS) or Hamilton Rating Scale for Depression (HAM-D). Of these subjects, 21 % (5) were diagnosed with MDD, and 8% (2) with dys thymia.

89, p=0.57) differed between the groups. On subset analysis, patient

with squamous cell tumors had a better progression-free survival with CRT (HR 0.47, p=0.014) than those with non-squamous tumors (HR=1.02, p=0.92). Weaknesses of this trial included administration of only one cycle of chemotherapy and relatively low radiation doses. INK 128 concentration Multiple trials have evaluated preoperative chemoradiation therapy with some improvement in survival outcomes and notable pathological complete response rates as detailed in Table 2. Table 2 Trials of preoperative chemoradiotherapy Preoperative chemoradiotherapy versus definitive chemoradiotherapy Some authorities Inhibitors,research,lifescience,medical believe that the role of surgery for squamous cell carcinomas remains controversial based on two studies, one from France and another from Germany. The Federation Francophone Inhibitors,research,lifescience,medical de Cancerologie Digestive Study 9102 enrolled 444 patients with resectable squamous cell carcinoma (89%) or adenocarcinoma (11%), to receive one of two radiation schemes with 2 courses of concurrent cisplatin Inhibitors,research,lifescience,medical and 5-FU: 1) protracted radiotherapy (46 Gy over 4.5 weeks) (64% of participants)

or 2) split course radiotherapy with two 1-week courses of 15 Gy with a 2 week break (36%) (17). 259 patients who responded to therapy were randomly assigned to surgery or additional chemoradiation. For the non-responders, they continued on a course of CRT with an additional 20 Gy for the protracted course and 15 Gy for the split course CRT. No significant differences were seen in median survival and (17.7 months in those who underwent surgery compared to Inhibitors,research,lifescience,medical 19.3 months in the definitive CRT arm) 2-year survival (34% in surgery cohort vs 40% in the CRT arm, p=0.44). Nevertheless, the 2-year local control rate was higher with surgery (66%) compared to CRT (57%). The 3-month mortality rate was 9% in the surgery group and 1% in the CRT group. The results of this trial imply that for patients who respond to CRT, surgery may improve local control but not survival. In a similar Inhibitors,research,lifescience,medical study design by Stahl et al, 172 patients with locally advanced squamous

Sodium butyrate cell carcinoma of the esophagus were randomized to either induction chemotherapy (5-FU, leucovorin, etoposide, and cisplatin for 3 cycles) followed by CRT (40 Gy with cisplatin and etoposide) followed by surgery or the same induction chemotherapy followed by CRT (total dose of 60-65 Gy with or without brachytherapy) without surgery (18). Overall survival at 2-years (40% with surgery vs 35% with CRT) and median survivals (16 months vs 15 months) were equivalent. Freedom from local progression was improved with surgery (64% vs 41%, p=0.003). Surgery improved outcomes for non-responders to CRT who had 3-year survival rates of 18% with surgery compared to 9% with CRT alone. Treatment related mortality was also higher in the surgery arm (13% vs 3.5%, p=0.03).

These unacceptably very high posttreatment PSA nadir levels can only be explained by a totally inadequate ablation or poor selection of cases with occult metastatic disease. One

cannot condemn the technology, but rather the Bosutinib nmr surgeons whose poor surgical technique likely led to high failure rates. In the subset of men in the Ripert study who achieved posttreatment PSA nadirs < 0.2 ng/mL-which Inhibitors,research,lifescience,medical would reflect both good surgical technique and the selection of candidates who in fact have localized disease-approximately 75% of men achieved durable (6-year) biochemical-free survival. Dr. Uchida is a highly experienced HIFU surgeon who uses the Sonablate 500 device, which I believe is superior technology due to its more precise delivery of energy and monitoring

of tissue destruction compared with the Ablatherm device. Uchida and colleagues reported 5-year BCR rates of only 16% and 34% for low- and intermediate-risk disease, respectively, Inhibitors,research,lifescience,medical using the Phoenix definition of BCR.2 These are impressive outcomes and clearly rival those achieved with RT. In my opinion, these impressive outcomes reflect the advanced capabilities of Sonablate technology and the skill of the operator. There is no doubt that successful surgical outcomes are often related to clinical experience. A rigorous community-based Inhibitors,research,lifescience,medical study of outcomes following radical prostatectomy reported severe incontinence rates of approximately 10%.3 In the community setting, the average urologist performs about five radical prostatectomies a year, similar to the number performed by Ripert and colleagues. I have personally performed over Inhibitors,research,lifescience,medical 4000 radical prostatectomies and my reported severe incontinence rate is 2%. It is, therefore, not surprising that experienced HIFU surgeons achieve superior results, no different than experienced surgeons who perform radical prostatectomy as well as any complex surgical procedure. So, in my opinion, the Ripert report is consistent with the literature. When the prostate is appropriately ablated in legitimately selected cases, low PSA nadir levels are achieved. Even Ripert achieved good outcomes when the prostate Inhibitors,research,lifescience,medical was adequately

treated. The challenge, as with any new technology, is to minimize the learning Olopatadine curve for those who embrace this new technology.
Acute appendicitis presenting with renal colic secondary to ureteral stenosis is a very rare event.1 Our patient presented with an acute complicated appendicitis with stercolith and perforation causing appendiceal abscess and leading to right ureteral stenosis and hydronephrosis. Case Presentation A 60-year-old woman was admitted to the emergency room with a 7-day history of right renal colic and low abdominal pain. There were no urinary symptoms. Past medical history was unremarkable. On physical examination, her temperature was 39°;C/102°;F and the lower abdominal region was mildly tender upon palpation.

Importantly, similar patterns to those previously observed were apparent from the lower dose experiment.

As expected all antibody and T Bcl-2 inhibitor cell responses were substantially weaker when using lower vaccine doses. Responses to protein–protein vaccination were markedly more variable than responses to adenovirus-containing regimes. At these lower doses, addition of protein did not enhance the antibody immunogenicity of viral vector regimes, with no significant differences in ELISA titers following A–M, A–P, A–M–P or A–P–M vaccination. T cell responses were again substantially higher in the A–M, A–M–P and A–P–M groups than in the A–P group. As before, the (A+P)–M, A–(M+P) and (A+P)–(M+P) two-stage regimes mixing viral and protein vaccines produced results TSA HDAC datasheet similar to three-stage vaccination, with a trend towards higher antibody but lower CD8+ T cell responses in the group receiving (A+P)–(M+P). Thus despite the clearly sub-maximal responses achieved in these animals (in particular with the protein only vaccination), regimes

incorporating adenovirus and MVA again appeared to result in more consistent combined antibody and CD8+ T cell responses to the antigen. To further characterize the immune responses to the various vaccine modalities, we performed IgG isotype ELISAs. It was not possible to measure Modulators isotype-specific titers for the three P–P immunized mice with low total IgG ELISA titers. Bearing in mind this limitation, viral-vector-containing regimes induced a significantly greater ratio of IgG2a to IgG1 than was present in the high-total-titer P–P immunized mice, and that the IgG2a/IgG1 ratio was higher for all groups

137 days rather than 14 days after the final vaccination, corresponding to better maintenance of the titer of IgG2a than IgG1 over time (Fig. 7; P < 0.001 for both comparisons by repeated measures two-way ANOVA with Bonferroni's post-test). There was no interaction of STK38 time and regime (i.e. no inter-regime differences in the rate of change of the IgG isotype balance over time). We continued to investigate the responses to the various regimes by measuring antibody avidity using NaSCN antibody-displacement ELISA for selected groups and time points (Fig. 8A–C). Among mice receiving A–M and A–P regimes, we observed that mice receiving A–M had higher antibody avidity 14 days post-boost than those receiving A–P, without any significant difference between 57 day and 97 day dose interval (Fig. 8A; P = 0.024 for regime comparison, P = 0.33 for comparison dose interval by two-way ANOVA).

Any delay clearly means a poorer prognosis. OLITA: a successful biopsychosocial approach to the treatment of alcoholism Outpatient Long-term Intensive Therapy for Alcoholics (OLITA) is a four-step biopsychosocial outpatient therapy program for severely affected alcohol-dependent patients, aiming at immediate social reintegration within the sheltered setting of psychotherapeutic treatment and medical care. Therefore,

basic elements of psychiatric patient care, client-centered and cognitive-behavioral psychotherapy, as well as classical addiction therapy, Inhibitors,research,lifescience,medical are integrated into a comprehensive, intensive and long-term treatment approach (Tables I and II). In order to take into account both the impaired stress tolerance of the patients during early abstinence and the chronicity of the disease, the OLITA concept combines high intensity (ie, high frequency of therapy contacts) Inhibitors,research,lifescience,medical and long duration of therapy26,108 Following inpatient detoxification, the treatment extends over 2 years. The OLITA pilot study started in 1993 and was terminated successfully in 2003 after 10 years and the completion of 180 patients assigned to recruitment cohorts 1-6.94,106 The main therapeutic elements Inhibitors,research,lifescience,medical of OLITA are: (1) frequent contacts, selleck screening library Initially dally, with a slow reduction of contact frequency up to the

end of the second year; (ii) therapist rotation; (iii) support Inhibitors,research,lifescience,medical of social reintegration and aggressive aftercare; (iv) induction of alcohol intolerance

through application of alcohol deterrents (inhibitors of acetaldehyde dehydrogenase); (v) explicit control: supervised intake of alco hoi deterrents and regular urine analysis for alcohol and other drugs of abuse. The therapeutic phases of OLITA consist of the inpatient period (detoxification; 2 to 3 weeks; daily individual sessions, Inhibitors,research,lifescience,medical 15 minutes), the outpatient period i (intensive phase; 3 months; daily individual sessions, 15 minutes), the outpatient period II (stabilizing phase; 3 to 4 months according to individual need; three times a week individual sessions, 15 minutes), the outpatient period III (weaningoff phase; 6 months; twice a week individual Sitaxentan sessions, 30 minutes), and outpatient period iV (aftercare phase; 12 months; once weekly group session; initially once weekly individual session, 30 minutes, which is gradually tapered off). After completion of the 2 years of therapy, patients participate in weekly to quarterly follow-up contacts and are offered to make use of both the emergency service and the crisis interventions of the therapeutic team.

combining software (including design of experiment, sample tracking, data visualization, and analysis), hardware (liquid dispensing, plate handling, and fluorescence imaging), and experimental workflow (Fig. 2b) (Development of an integrated high throughput system for identifying formulations of live virus vaccines with greater thermostability: application to the monovalent measles vaccine; manuscript in preparation). A combination of in-house designed, custom modified, and off-the-shelf hardware and software were used. The impact of intra- and inter-plate systematic variability typical of cell-based assays in microtiter plate formats [32] was reduced through careful experimental design choices and data normalization using on-plate controls. The solutions implemented to overcome these challenges will be discussed in greater detail separately (Maximizing the value of cell-based high throughput screening

data through experimental design and data normalization; manuscript in preparation). In HT small molecule screening it is common practice to evaluate the performance of the assay based on the negative and positive controls (Z′) [33] and the proportion of hits found (i.e. hit rate). In thermal stability screening of virus

formulations, neither a true negative control (no infectivity) nor a true positive control is informative. learn more In theory, it is possible to benchmark formulation performance against either a commercial vaccine or the pre-thermal challenge viral titer for each assay. However, this proved impossible in practice due to the limited availability of monovalent vaccine and the impracticality of processing non-thermally challenged control plates simultaneously see more with thermally challenged samples. In practice, the primary goal of identifying formulations capable of thermally stabilizing the virus was readily achieved through simple rank ordering of formulation performance, followed by validation of ‘high performing’ hits using manual assays such as plaque assays. A formalized screening strategy to guide experimental design was applied. A list of >200 excipients including buffers, stabilizers, solubilizers, preservatives, and tonicifiers compiled from marketed parenteral formulations, the FDA ‘Generally Regarded As Safe’ (GRAS) list, and the literature was Libraries narrowed based on considerations of safety, cost, manufacturing, and ethical issues. Ultimately, 98 unique excipients were screened (Supplementary Table Online). The fully combinatorial formulation space represented by 98 excipients is many orders of magnitude larger (1 × 109 unique formulations with just 6 excipients each) than is tractable, even for HT screening (∼104).

An example of a new indication for an old drug is that of

An example of a new indication for an old drug is that of inhaled INCB018424 in vitro CORTICOSTEROIDS in chronic obstructive pulmonary disease (COPD) and metformin, an anti-diabetic medication, which has been receiving much attention recently as a potential anti-cancer agent, primarily on the basis of several observational studies Inhibitors,research,lifescience,medical that reported impressive reductions in the incidence of and mortality from cancer. These observational

studies formed the impetus for the conduct of major large-scale randomized trials. In this paper, we show that the spectacular effects reported in many of the observational studies that have been conducted in this context are the result of time-related biases, particularly immortal time bias which tends to exaggerate the benefits observed with a drug. We also show how the studies could have avoided this bias, and the ones that did actually reported null effects. With this knowledge, it is unlikely Inhibitors,research,lifescience,medical that randomized trials would have been conducted. INHALED CORTICOSTEROIDS IN COPD Chronic obstructive pulmonary disease, a disease that encompasses emphysema, chronic obstructive bronchitis, and small airway obstruction, is characterized by largely irreversible airflow obstruction.10 It currently affects Inhibitors,research,lifescience,medical around 10% of the population over the age of 40 years

and has recently become the third leading cause of death in the US.11,12 The pharmacological treatment of COPD has generally consisted of bronchodilators. However, because of the presence of inflammation in COPD, inhaled corticosteroids, which had been shown to be highly effective for the treatment of asthma, were readily adopted in COPD in the 1980s despite the fact Inhibitors,research,lifescience,medical that no randomized controlled trials had yet evaluated their effectiveness in this indication. The earliest randomized controlled trials to evaluate inhaled

corticosteroids in the treatment of COPD were only published in the late 1990s. The first seven trials Inhibitors,research,lifescience,medical found no improvement in the decline of lung function over time and, except for the last two trials, found no reduction in exacerbation rates Phosphatidylinositol diacylglycerol-lyase with various inhaled corticosteroids (ICS) compared with placebo, over periods ranging from 6 months to 3 years.13–19 In the early 2000s, the next wave of randomized controlled trials all involved the evaluation of inhaled corticosteroids combined with a long-acting beta-agonist.20–25 Most of these trials reported significant effects on lung function and reductions in exacerbation rates with the combination therapy, while the effects of inhaled corticosteroids alone were equivocal. Thus, the totality of these trials can be concluded to imply that any effectiveness of these medications is driven primarily by the long-acting beta-agonist component.

Acute liver failure was diagnosed by the presence of coagulopathy

Acute liver failure was diagnosed by the Palbociclib datasheet presence of coagulopathy (prothrombin time [PT] international normalized ratio [INR] ≥1.5), any degree of hepatic encephalopathy, and length of illness ≤24 weeks [1]. Acute liver failure was also confirmed by the medical history, clinical findings, biochemical test, viral serologies, and imaging methods. The exclusion criteria for entry into the study were: 1) clinical evidence of severe cerebral edema or cerebral herniation at the time of admission, 2) no consent to on-line HDF by patient or relatives, and 3) obvious improvement

of condition at the time Inhibitors,research,lifescience,medical of hospitalization. Eight patients with acute liver failure admitted during the study period were excluded from the analysis on the basis of these exclusion criteria. Three patients presented deep coma, and severe Inhibitors,research,lifescience,medical cerebral edema at the time of admission. All these 3 patients also presented multiple organ failure, and died 1, 2, and 4 days after admission, respectively. In a patient who presented hypovolemic shock due to dehydration, we could Inhibitors,research,lifescience,medical not obtain the consent because he did not have relatives, and standard medical therapy improved his consciousness promptly. In the remaining 4 patients who presented acute liver failure due to congestion, the treatment for congestive heart failure improved

their condition with no need of ALS. Ultimately 17 patients were included in this study. The characteristics of the participating patients (baseline clinical and Inhibitors,research,lifescience,medical laboratory data) are summarized in Table ​Table1.1. There were 11 men, aged 26-72 years (49.3 ± 4.3 years), and 6 women, aged 21-52 years (40.7 ± 4.5 years). The etiology of acute liver failure was hepatitis B virus infection in 10 patients, non-A~G hepatitis

virus infection Inhibitors,research,lifescience,medical in 2 (indeterminate), alcoholic suspected with the medical history in 2, congestive liver in 1, infiltration of leukemia cells in 1, and acetaminophen overdose in 1. In eight patients of 10 patients who suffered from hepatitis B virus infection, the hepatitis B surface antigen and an IgM antibody to the hepatitis B core antigen were positive (acute infection). In the remaining 2 patients, the medical history that they had been healthy carriers of hepatitis B virus was proven by their medical records, and viral serologies on admission revealed acute exacerbation of hepatitis B infection. Acute liver failure developed in a patient of these 2 patients Linifanib (ABT-869) after the interruption of administration of steroids for multiple myeloma. The average time from the onset of the disease until admission to the hospital was 10.4 ± 3.3 days with a range of 3-60 days. Eleven of the 17 patients had encephalopathy on admission, and the remaining 6 had encephalopathy 2.7 ± 0.9 days after admission with a range of 1-6 days.
