Perioperative tobacco use treatments: putting them into practice.

Treatment for tobacco use is efficacious and beneficial to health. Although guidelines recommend that all patients who use tobacco are offered treatment as a part of their clinical care, implementing treatment has proven challenging. In the case of surgical patients, this lack of treatment is particularly unfortunate, as the benefits of abstinence from tobacco are immediate in terms of reducing the risk of surgical complications, including cardiovascular, respiratory, and wound related complications. Surgery also presents an opportunity for patients to quit for good and reduce the long term health risk. This review examines the principles of tobacco use treatment, the rationale for tobacco use treatment in the perioperative period, and how treatment can be incorporated into the routine care of surgical patients. The discipline of implementation science helps to frame these efforts by seeking to better understand how changes in clinical practice occur, and it has the potential to guide an evidence based approach to embedding tobacco treatment into the routine clinical care of surgical patients. This review uses the consolidated framework for implementation research, which includes five major domains, as a representative conceptual framework. A basic understanding of factors potentially important to successful implementation can help to guide clinicians who accept the challenge of implementing tobacco use treatment in surgical care.

Editorial: Severe Acute Liver Injury: Cause Connects to Outcome.

Severe acute liver injury (ALI) is a common condition with little objective study of its natural history and outcomes. In this paper by Koch et al. and the Acute Liver Failure (ALF) Study Group, the authors utilize a consensus definition of ALI requiring newly elevated bilirubin, alanine aminotransferase (ALT), and international normalized ration (INR) without evidence of hepatic encephalopathy (HE), with HE as the key differentiator of ALI from ALF. They show significantly higher rates of progression to ALF, liver transplantation, or death in non-acetaminophen etiologies of ALI. This study's findings provide guidance in supporting careful allocation of scarce critical care and liver transplant resources for ALI patients.

Methotrexate Hepatotoxicity and the Impact of Nonalcoholic Fatty Liver Disease.

Methotrexate (MTX) is commonly used to treat individuals with rheumatological and dermatologic disorders. Current American College of Rheumatology (ACR) and American Association of Dermatology (AAD) guidelines identify diabetes and obesity as risk factors for MTX-induced liver injury. Both diabetes and obesity are components of the metabolic syndrome, and are also risk factors for nonalcoholic fatty liver disease (NAFLD). NAFLD affects approximately 40% of the U.S. population, and those with more advanced NAFLD (i.e., nonalcoholic steatohepatitis with or without fibrosis) are likely to develop progressive liver disease. As such, individuals who are treated with MTX may need to be screened for advanced NAFLD, as this may put them at an increased risk of MTX-induced liver injury. In this mini-review, we review the current ACR and AAD guidelines on MTX hepatotoxicity, discuss the evidence (or lack thereof) of the impact of metabolic risk factors on MTX-induced liver injury and highlight the areas that need further research.

Human Brain Abnormalities Associated With Prenatal Alcohol Exposure and Fetal Alcohol Spectrum Disorder.

Fetal alcohol spectrum disorder (FASD) is a common neurodevelopmental problem, but neuropathologic descriptions are rare and focused on the extreme abnormalities. We conducted a retrospective survey (1980-2016) of autopsies on 174 individuals with prenatal alcohol exposure or an FASD diagnosis. Epidemiologic details and neuropathologic findings were categorized into 5 age groups. Alcohol exposure was difficult to quantify. When documented, almost all mothers smoked tobacco, many abused other substances, and prenatal care was poor or nonexistent. Placental abnormalities were common (68%) in fetal cases. We identified micrencephaly (brain weight <5th percentile) in 31, neural tube defects in 5, isolated hydrocephalus in 6, corpus callosum defects in 6 (including some with complex anomalies), probable prenatal ischemic lesions in 5 (excluding complications of prematurity), minor subarachnoid heterotopias in 4, holoprosencephaly in 1, lissencephaly in 1, and cardiac anomalies in 26 cases. The brain abnormalities associated with prenatal alcohol exposure are varied; cause-effect relationships cannot be determined. FASD is likely not a monotoxic disorder. The animal experimental literature, which emphasizes controlled exposure to ethanol alone, is therefore inadequate. Prevention must be the main societal goal, however, a clear understanding of the neuropathology is necessary for provision of care to individuals already affected.

Trends in Deaths Involving Heroin and Synthetic Opioids Excluding Methadone, and Law Enforcement Drug Product Reports, by Census Region - United States, 2006-2015.

Opioid overdose deaths quadrupled from 8,050 in 1999 to 33,091 in 2015 and accounted for 63% of drug overdose deaths in the United States in 2015. During 2010-2015, heroin overdose deaths quadrupled from 3,036 to 12,989 (1). Sharp increases in the supply of heroin and illicitly manufactured fentanyl (IMF) are likely contributing to increased deaths (2-6). CDC examined trends in unintentional and undetermined deaths involving heroin or synthetic opioids excluding methadone (i.e., synthetic opioids)* by the four U.S. Census regions during 2006-2015. Drug exhibits (i.e., drug products) obtained by law enforcement and reported to the Drug Enforcement Administration's (DEA's) National Forensic Laboratory Information System (NFLIS) that tested positive for heroin or fentanyl (i.e., drug reports) also were examined. All U.S. Census regions experienced substantial increases in deaths involving heroin from 2006 to 2015. Since 2010, the South and West experienced increases in heroin drug reports, whereas the Northeast and Midwest experienced steady increases during 2006-2015.(†) In the Northeast, Midwest, and South, deaths involving synthetic opioids and fentanyl drug reports increased considerably after 2013. These broad changes in the U.S. illicit drug market highlight the urgent need to track illicit drugs and enhance public health interventions targeting persons using or at high risk for using heroin or IMF.

Overdose Deaths Related to Fentanyl and Its Analogs - Ohio, January-February 2017.

Ohio is experiencing unprecedented loss of life caused by unintentional drug overdoses (1), with illicitly manufactured fentanyl (IMF) emerging as a significant threat to public health (2,3). IMF is structurally similar to pharmaceutical fentanyl, but is produced in clandestine laboratories and includes fentanyl analogs that display wide variability in potency (2); variations in chemical composition of these drugs make detection more difficult. During 2010-2015, unintentional drug overdose deaths in Ohio increased 98%, from 1,544 to 3,050.* In Montgomery County (county seat: Dayton), one of the epicenters of the opioid epidemic in the state, unintentional drug overdose deaths increased 40% in 1 year, from 249 in 2015 to 349 in 2016 (estimated unadjusted mortality rate = 57.7 per 100,000) (4). IMFs have not been part of routine toxicology testing at the coroner's offices and other types of medical and criminal justice settings across the country (2,3). Thus, data on IMF test results in the current outbreak have been limited. The Wright State University and the Montgomery County Coroner's Office/Miami Valley Regional Crime Laboratory (MCCO/MVRCL) collaborated on a National Institutes of Health study of fentanyl analogs and metabolites and other drugs identified in 281 unintentional overdose fatalities in 24 Ohio counties during January-February 2017. Approximately 90% of all decedents tested positive for fentanyl, 48% for acryl fentanyl, 31% for furanyl fentanyl, and 8% for carfentanil. Pharmaceutical opioids were identified in 23% of cases, and heroin in 6%, with higher proportions of heroin-related deaths in Appalachian counties. The majority of decedents tested positive for more than one type of fentanyl. Evidence suggests the growing role of IMFs, and the declining presence of heroin and pharmaceutical opioids in unintentional overdose fatalities, compared with 2014-2016 data from Ohio and other states (3-5). There is a need to include testing for IMFs as part of standard toxicology panels for biological specimens used in the medical, substance abuse treatment, and criminal justice settings.

Alcohol or Drug Use and Trauma Recidivism.

Alcohol, illicit drugs, and psychotropic medications are well-known causes of traumatic events. However, the association of each type of substance with trauma recidivism remains unclear.

Botulism: Diagnosis and Therapy.

Background Botulism is a rare, life-threatening, time-critical neuroparalytic disease that is frequently a subject of differential diagnostic considerations. But there is much uncertainty regarding diagnosis and therapy. Rapid diagnosis, early antitoxin dose, consistent food hygiene and the sensitization of the population can help to reduce incidence, morbidity and mortality. Methods This overview is based on an epidemiological data inquiry (RKI, ECDC, CDC, WHO) and a selective literature research (pubmed till March 2017). Additionally, the German botulism guideline (2012) and own diagnostical experiences were taken into account. Results The incidence of botulinum toxin intoxication induced by ubiquitous spore-forming Clostridium botulinum (main representative) is < 0.01/100 000 EU citizens. Foodborne botulism is a pure intoxication syndrome (most common form) due to improperly prepared or incorrectly stored food. Wound and infant botulism are kinds of "toxico-infections". A "bulbar" neuroparalysis is a main symptom progressing to a flaccid tetraparesis up to respiratory paralysis. Infant botulism is presented non-specific and is treated only symptomatically; but a special human-derived antitoxin is available at international pharmacies. In case of suspected foodborne or wound botulism antitoxin must be administered as soon as possible, which may also be effective 24 hours after symptoms onset. There is no evidence for adjuvant treatment except of intensive care unit (ICU) therapy. Conclusion Despite typical symptomatology botulism is often diagnosed too late. Early antitoxin administration and ICU therapy are crucial for survival. A consultant laboratory should be contacted for advice.

Risk of Recurrence of Adverse Events Following Immunization: A Systematic Review.

Reimmunizing patients who had an adverse event following immunization (AEFI) is sometimes a challenge because there are limited data on the risk and severity of AEFI recurrence.

Chronic alcohol consumption regulates the expression of poly immunoglobulin receptor (pIgR) and secretory IgA in the gut.

The effect of ethanol (EtOH) on the gut immune system was analyzed using an experimental model previously described, where EtOH was provided ad libitum in the drinking water in a 20% w/v concentration for up to 12weeks. Dendritic cells, T cells and macrophages were analyzed in Peyer's patches and the small intestines using flow cytometry. Cytokine and immunoglobulin levels were analyzed in sera, feces, and homogenates from small and large intestines and lungs. Decreases in the proportion of T cells and alterations in dendritic cells and macrophages were observed after EtOH treatment. Levels of immunoglobulin A (IgA) increased in tissue homogenates but decreased in small intestine fecal contents. Meanwhile poly-immunoglobulin receptor (pIgR) levels decreased in tissue homogenates and fecal contents. Levels of cytokines associated with the regulation of pIgR expression decreased for IL-10 and TGF-β, and increased for IFN-γ and IL-17 in the small intestine. The data indicate that chronic EtOH consumption disrupts the homeostasis of the mucosal immune system by altering the phenotype and functionality of multiple immune cell types, leading to a diminished secretion of SIgA, due to pIgR expression decreased.

Giant Aortic Thrombus in the Ascending Aorta and Perforation of Bowel Associated With Cocaine Use.

A floating giant aortic thrombus is a rare finding in the absence of any coagulation disorder. Patients usually remain asymptomatic until the development of embolic complications. Our report highlights cocaine abuse as a potential cause of aortic thrombus and bowel perforation. Clinicians should have a high index of suspicion when treating patients with a history of illicit cocaine use with signs and symptoms of arterial ischemia. The risks of cardiovascular and abdominal complications related to cocaine use should not be underestimated. Prompt diagnosis is required to circumvent potentially life-threatening complications.

Endogenous Fungal Endophthalmitis: An Increasing Problem Among Intravenous Drug Users.

Case Report: Polymerase Chain Reaction Testing of Tick Bite Site Samples for the Diagnosis of Human Granulocytic Anaplasmosis.

Human granulocytic anaplasmosis (HGA) is a tick-borne infectious disease caused by Anaplasma phagocytophilum, an obligate intracellular bacterium. Until now, the utility of tick-bite site samples for HGA diagnosis has not been reported. Using a patient's buffy coat and tick-bite site crust samples, we performed polymerase chain reaction (PCR) testing using Ehrlichia- or Anaplasma-specific primers. PCR with buffy coat and crust samples obtained before doxycycline administration was positive. Six days after doxycycline administration, PCR with the buffy coat sample was negative but PCR with a crust tissue sample from the tick-bite site remained positive. This is the first case to suggest that crust tissue at the tick-bite site may be useful for early HGA diagnosis in patients who have already been treated with antibiotics such as doxycycline.

Clinical Usefulness of Real-Time Polymerase Chain Reaction for the Diagnosis of Vibrio vulnificus Infection Using Skin and Soft Tissues.

Vibrio vulnificus is a halophilic gram-negative bacillus isolated in seawater, fish, and shellfish. Infection by V. vulnificus is the most severe food-borne infection reported in the United States of America. Here, we aimed to examine the clinical usefulness of polymerase chain reaction (PCR) using tissue specimens other than blood samples as a diagnostic tool for V. vulnificus infection. A retrospective study was conducted with patients who underwent real-time PCR of toxR in both blood and skin tissues, including serum, bullae, swab, and operation room specimens, between 2006 and 2009. The median V. vulnificus DNA load of 14 patients in real-time PCR analysis of serum at the time of admission was 638.5 copies/mL blood, which was within the interquartile range (IQR: 37-3,225). In contrast, the median value by real-time PCR using the first tissue specimen at the time of admission was 16,650 copies/mL tissue fluid (IQR: 4,419-832,500). This difference was statistically significant (P = 0.022). DNA copy numbers in tissues were less affected by short-term antibiotic administration than that in blood samples, and antibiotic administration increased the DNA copy number in some patients. We found, for the first time, that DNA copy numbers in tissues of patients infected by V. vulnificus were higher than those in blood samples. Additionally, skin lesions were more useful than blood samples as specimens for PCR analysis in patients administered antibiotics for V. vulnificus infection before admission.

A prospective cohort study of the effectiveness of the primary hospital management of all snakebites in Kurunegala district of Sri Lanka.

Integrative analysis of hepatic microRNA and mRNA to identify potential biological pathways associated with monocrotaline-induced liver injury in mice.

Pyrrolizidine alkaloids (PAs) are a type of natural hepatotoxic compounds. Monocrotaline (MCT), belongs to PAs, is a main compound distributed in medicinal herb Crotalaria ferruginea Grah. ex Benth. This study aims to identify the potential biological signaling pathway associated with MCT-induced liver injury by analyzing the integrative altered hepatic microRNA (miRNA) and mRNA expression profile. C57BL/6 mice were orally given with MCT (270, 330mg/kg). Serum alanine/aspartate aminotransferase (ALT/AST) activity, total bilirubin (TBil) amount and liver histological evaluation showed the liver injury induced by MCT. Results of miRNA chip analysis showed that the hepatic expression of 15 miRNAs (whose signal intensity>200) was significantly altered in MCT-treated mice, and among them total 11 miRNAs passed further validation by using Real-time PCR assay. Results of mRNA chip analysis demonstrated that the hepatic expression of 569 genes was up-regulated and of other 417 genes was down-regulated in MCT-treated mice. There are total 426 predicted target genes of those above altered 11 miRNAs, and among them total 10 genes were also altered in mice treated with both MCT (270mg/kg) and MCT (330mg/kg) from the results of mRNA chip. Among these above 10 genes, total 8 genes passed further validation by using Real-time PCR assay. Only 1 biological signaling pathway was annotated by using those above 8 genes, which is phagosome. In conclusion, this study demonstrated the integrative altered expression profile of liver miRNA and mRNA, and identified that innate immunity may be critically involved in MCT-induced liver injury in mice.
