This study evaluated explanations of rape fantasy in a sample of female undergraduates (N = 355) using a sexual fantasy checklist which included eight types of rape fantasy, participants' detailed descriptions of a rape fantasy they have had, a rape fantasy scenario audio presentation, and measures of personality. Three explanations of rape fantasy were tested: openness to sexual experience, sexual desirability, and sexual blame avoidance. Women who were higher in erotophilia and self-esteem and who had more frequent consensual sexual fantasies and more frequent desirability fantasies, particularly of performing as a stripper, had more frequent rape fantasies. Women who were higher in erotophilia, openness to fantasy, desirability fantasies, and self-esteem reported greater sexual arousal to rape fantasies. Sexual blame avoidance theory was not supported; sexual desirability theory was moderately supported; openness to sexual experience theory received the strongest support.

A 21-year-old man was found dead in a car. There were 9 empty bottles of 610HAP (a 440 g bottle of a liquid bath essence containing 160-195 g/kg sulfur) and 10 of Sunpole (a 500 mL bottle of a toilet bowl cleaner containing 9.5% HCl) in the car. The car doors were sealed with tape, and there was a strong smell of sulfur in and around the car. GC/MS analysis showed 0.66 microg/mL sulfide and 0.14 micromol/mL thiosulfate in the blood sample. The concentration of thiosulfate in the urine sample was normal. Police investigation concluded that the man killed himself by aspirating hydrogen sulfide that had been produced by mixing 610 HAP and Sunpole. To examine the amount of hydrogen sulfide produced, small portions of these liquids were mixed in a 560-mL volume flask. The results showed that 0.1 mL of each liquid produced 4,950 ppm of hydrogen sulfide, and 0.2 mL of each produced 10,800 ppm. According to these results, if the cabin volume is assumed to be 3,300 L, mixing 120 mL of each liquid produces a lethal level of hydrogen sulfide, i.e., 1,000 ppm. This was a rare suicide case, and it revealed the hazards of mixing of liquid bath essences containing sulfur and toilet bowl cleaners containing hydrochloric acid.

The effect of cisapride on plasma concentrations of paracetamol was investigated with respect to hepatic metabolism. Paracetamol (1 g) together with cisapride (7.5 mg) or placebo was orally administered to five healthy male volunteers. Venous blood samples were taken before and after administration. Plasma paracetamol and its glucuronide and sulfate conjugates were measured by HPLC. The pharmacokinetic variables were calculated from the plasma concentration-time curves of each volunteer. The area under the plasma paracetamol concentration-time curve from 0 to 180 min (mean +/- s.d.) increased from 1875.0 +/- 112.8 micrg min mL(-1) (placebo coadministration) to 2238.8 +/- 125.8 microg min mL(-1) (cisapride coadministration) (P < 0.01). The mean maximum plasma paracetamol concentration(18.2 microg mL(-1))with placebo was reached 30 min after administration, whereas mean maximum plasma paracetamol concentration (21.2 microg mL(-1)) with cisapride occurred 45 min after administration. The plasma paracetamol concentrations with cisapride were significantly greater at 45 to 120 min after administration compared with placebo. Plasma paracetamol glucuronide conjugate concentrations with cisapride were decreased at 15 to 60 min compared with placebo (P< 0.05), whereas plasma paracetamol sulfate conjugate concentrations did not change significantly. Hence the coadministration of paracetamol with cisapride reduced plasma paracetamol glucuronide concentrations and increased plasma paracetamol concentrations, presumably due to inhibition of paracetamol metabolism via paracetamol glucuronyltransferase. Thus, care is necessary when paracetamol and cisapride are coadministered.

A case is presented of a fatal drug interaction caused by ingestion of oxycodone (Oxycontin) and clonazepam (Klonapin). Oxycodone is an opium alkaloid used in long-term pain management therapy. Clonazepam is a benzodiazepine used for the treatment of seizures and panic disorders. The Drug Abuse Warning Network (DAWN) has reported an increase of 108% in the last two years of emergency department episodes related to Oxycontin. Six billion prescriptions were written for Oxycontin in the year 2000, an 18-fold increase from four years previous (1). Oxycontin has recently gained enormous notoriety at the local and national levels; however, there are very few previously documented cases of lethal drug interactions between oxycodone and clonazepam. Synergistic effects between these two drugs are postulated to arise from different agonistic mechanisms producing similar physiological changes. It is also theorized that clonazepam may inhibit the metabolism of oxycodone. A 38-year-old white female was found dead in Jefferson County, Tennessee in March of 2001. The deceased had physical evidence of previous drug abuse and positive serological findings of hepatitis B and C. Prescription pill bottles filled under the name of the deceased, as well as another name, were found with the body. Serum, urine and gastric contents from the deceased were screened for numerous drugs and metabolites using a combination of thin layer chromatography and immunoassay techniques (EMIT and FPIA). Analysis of biological specimens from the deceased revealed the presence of: benzodiazepines, opiates (oxycodone), and trazodone metabolites in the serum; cannabinoids, benzodiazepines, opiates (oxycodone), trazodone, trazodone metabolites, nicotine, and nicotine metabolite in the urine; and benzodiazepines, opiates (oxycodone), nicotine, and nicotine metabolite in the gastric contents. Quantitative analyses for clonazepam was performed by high performance liquid chromatography (HPLC) and revealed a plasma concentration of 1.41 microg/mL. Plasma oxycodone and urine 11-nor-carboxy-delta-9-tetrahydrocannabinol concentrations were determined by gas chromatography/mass spectrometry and revealed concentrations of 0.60 microg/mL and 27.9 ng/mL, respectively. The deceased had pathologies consistent with severe central nervous system (CNS) and respiratory depression produced by high concentrations of clonazepam and oxycodone including collapsed lungs, aspirated mucus, and heart failure. The pathologies were sufficient to cause death, which was officially attributed to a drug overdose; however, the manner of death was unknown.

The positive effect of bromantan (0.5-50 mg/kg) on the efficiency of physical work of mice and rats (swimming test, running on a treadmill) exceeds that of phenamine administered in optimal doses by 1.3-1.6 times. Such an effect of bromantan lasts no less than 24 h. The drug delays decrease of physical efficiency and restores it sooner in repeated extreme running loads, prevents in rats the corresponding electron-microscopic changes in the cardiomyocyte and myocyte mitochondria of the skeletal muscles. The data obtained suggest that the positive effect of bromantan on the physical efficiency is associated not only with its psychostimulating action but also with the membrane-protecting effect.

Sandpaper leaf (Ficus exasperata) is commonly used in folk medicine to manage high blood pressure. However, different methods such as soaking, boiling, hand maceration, and blending have been employed for preparing sandpaper leaf extracts for hypertensive patients. This study sought to investigate and compare the influence of different processing methods on the antihypertensive properties of sandpaper leaf as well as its effect on Fe2+ and sodium nitroprusside- (SNP-) induced lipid peroxidation in rat heart in vitro. Sandpaper leaf extracts were prepared using different methods and the resulting solutions were freeze-dried. Effect of the extracts on angiotensin-1-converting enzymes (ACE) and arginase activity was assessed. Thereafter, antioxidant activities of the extracts were determined using in vitro antioxidant assays, and the total phenolic content and flavonoid content of the extracts were determined. The results revealed that sandpaper leaf extracts from different processing methods inhibited ACE and arginase activity in a dose-dependent manner. However, the soaking method had significantly (p < .05) higher inhibitory effect on angiotensin converting (ACE) and arginase activity than hand maceration, boiling, and blending methods. Sandpaper leaf extracts also exhibited high antioxidant activities as typified by their iron-chelating ability, 2, 2'-azino-bis (3-ethylbenzthiazoline-6-sulphonic acid) (ABTS) radical-scavenging and iron-chelating ability as well as inhibition of Fe2+- and SNP-induced lipid peroxidation in rat heart in vitro. Processing methods alter the inhibitory effect of sandpaper leaf extracts on ACE and arginase activities. Thus, inhibition of ACE and arginase coupled with antioxidant properties could offer protective mechanisms against hypertension. However, the soaking method appears to be the most promising among methods considered.

Hoodoo is a folk belief system common among black Americans. Conjuration and rootwork are other terms used to describe this system which includes the casting of spells and witchcraft. This paper describes the black folk concept of 'white liver', an aspect of hoodoo which bears striking resemblance to AIDS. White liver refers to a condition characterized by sexual excess and a wasting to death of sexual partners. Although clearly antedating by many years the current AIDS epidemic, white liver is important as a contemporary black cultural entity that may be used to describe AIDS or to articulate a fear of AIDS.

Asphyxial suicide by placing a plastic bag over the head, especially in combination with inhalation of gases, is a rarely described method of committing suicide. This article reports a case of suicidal asphyxiation by inhaling the inert gas helium inside a plastic bag. A 64-year-old man probably followed the instructions described in an article about committing suicide written by a medical practitioner from Zürich. This form of suicide is recommended by right-to-die groups and in the internet as a certain, fast, and painless suicide method. Additionally, it leaves only seldom externally visible marks or pathomorphological findings on the body. If the plastic bag and other auxiliary means are removed by another person, the forensic death investigation of cause and manner of death may be very difficult. Therefore, the death scene investigation and the inquiry ordered in the environment of the deceased are very important.

Most cases of fatal hypothermia are accidental, often in connection with alcoholisation, homelessness, age-related confusedness and others. The phenomenon of paradoxical undressing may be observed. A paradoxical feeling of warmth in the advanced condition of hypothermia leads to the behaviour of undressing, partly or completely. Suicides with intentional hypothermia are rare. Fatal hypothermia often appears as a concomitant mechanism, e. g. in drug poisoning. The case report describes the fatality of a young woman dying from suicidal hypothermia. She was found partly undressed. This was part of her scheduled plan and not a consequence of paradoxical undressing.

We describe a novel basic leucine zipper transcription factor, XXBP-1, which interacts with BMP-4 in a positive feedback loop. It is a maternal factor and is zygotically expressed in the dorsal blastopore lip and ventral ectoderm with the exception of the prospective neural plate during gastrulation. Overexpression of XXBP-1 leads to ventralization of early embryos as described for BMP-4, and inhibits neuralization of dissociated ectoderm. Consistent with mediating BMP signaling, we show that the ectopic expression of XXBP-1 recovers the expression of epidermal keratin and reverses the dorsalization imposed by truncated BMP receptor type I, indicating that it may act downstream of the BMP receptor. Its effects can be partially mimicked by a fusion construct containing the VP16 activator domain and the XXBP-1 DNA-binding domain. In contrast, fusing the DNA-binding domain to the even-skipped repressor domain leads to upregulation of the neural markers NCAM and nrp-1 in animal cap assay. Taken together, the results suggest a role for XXBP-1 in the control of neural differentiation, possibly as an activator.

This case report describes a 39-year-old male with remote history of polysubstance use disorder and depression who developed tinnitus after use of inhaled N,N-dimethyltryptamine (DMT). Although development of ear ringing was attributed to use on a single occasion, tinnitus occurred within the context of a larger self-experiment involving weekly microdoses of lysergic acid diethylamide (LSD). Distress and anxiety over the ear ringing prompted evaluation by an audiologist, primary care physician, and consultant psychopharmacologist. Tinnitus persisted for several months, although intensity and ability to cope with symptoms improved over time. A microdose of psilocybin mushrooms exacerbated tinnitus on two separate occasions, after which psychedelics were discontinued. Psychedelics are associated with a range of acute sensory changes including auditory phenomenon, although have not previously been associated with tinnitus in medical literature. Here, we present a probable case of tinnitus associated with DMT use and review potential underlying mechanisms connecting psychedelics and tinnitus.

Vaginal infections /VI/ represent some of the most common diseases by infection of FGS. The aim of this study is to analyze clinical and bacteriological efficacy of Polygynax in the treatment of vaginal infections and to take into account the correlation between the results of microbiological controls and reduction of clinical symptoms. The study included 100 patients, including 50 pregnant and non-pregnant 50 for a period of 3 months. All of them was diagnosed with vaginitis clinical examination, taken material from vagina for microbiological testing. The studied women was conducted targeted therapy Polygynax 12 capsules, in the form of vaginal capsules for 12 days, after which the sample control microbiology. Behind the subjective complaints of the patient and to reduce them as a result of treatment. The effective implementation of Polygynax 12 capsules is equally good as in non-pregnant and pregnant women. In a summary of the survey data to make relevant analyzes and conclusions from the results.

Experimental observation was made on the effect of GFDH pills and their oral liquid preparation on thymus and spleen weight, formation of the antibody haemolysis plaque and phagocytic function of the macrophages of peritoneal cavity. The result revealed that both GFDH pills and their oral liquid preparation were found helpful to the enhancement of immunological function. The oral liquid preparation also increased markedly the plasma level of testosterone in immature rats.

A liveborn female with a 69,XXX karyotype and clinical features of triploidy syndrome is reported. Main phenotypical features are: intrauterine growth retardation, hypotonicity, micrognathism, low-set ears, ocular anomalies, syndactyly and atrophy of the cerebral cortex and corpus callosum. Study of chromosomal heteromorphisms revealed that triploidy might have arisen through fertilization of a diploid ovum by a haploid sperm (diginy).

Vitaherpavac, a dry inactivated herpes simplex virus (HSV) culture vaccine, has been obtained, by using the Vero B continuous cell line as a substrate for accumulation of herpes simplex virus types 1 (US strain) and 2 (VN strain). Vitaherpavac and the similar vaccine Herpovax made by the Research Institute of Vaccines and Sera, Saint Petersburg (for which preparation a primary trypsinized chick embryo cell culture used as a substrate for accumulation of HSV types 1 and 2), underwent comparative clinical trials. The tolerability and therapeutic effectiveness of the vaccine were tested in patients diagnosed as having chronic frequently recurring herpes. The trials have yielded positive results that suggest that it is expedient to introduce of the new vaccine Vitaherpavac into practice to treat chronic recurrent herpetic infection of various localizations. Vitaherpavac has been registered in the Russian Federation and permitted for medical application.

Nosodes and sarcodes (homeopathic remedies gained primarily from disease products respectively organs of human or animal origin) are groups of drugs which were added to the homeopathic Materia Medica in the 1830s. Most substances used in nosode or sarcode therapy have a long medical tradition, with some even going back to the pre-Christian period. My contribution first describes therapeutic practices that use these substances and then juxtaposes them with their use in the early days of homeopathic nosode and sarcode therapy. The investigation shows, on the one hand, that there are aspects common to both approaches that go far beyond the mere choice of substances. On the other hand, it demonstrates the effect the inclusion of human or animal body substances in the homeopathic Materia Medica has had on homeopathy, as their use is no longer in line with what is considered rational.

Corynebacterium callunae and Corynebacterium efficiens are close relatives of the glutamate-producing mycolata species Corynebacterium glutamicum. The properties of the pore-forming proteins, extracted by organic solvents, were studied. The cell extracts contained channel-forming proteins that formed ion-permeable channels with a single-channel conductance of about 2 to 3 nS in 1 M KCl in a lipid bilayer assay. The corresponding proteins from both corynebacteria were purified to homogeneity and were named PorH(C.call) and PorH(C.eff). Electrophysiological studies of the channels suggested that they are wide and water-filled. Channels formed by PorH(C.call) are cation-selective, whereas PorH(C.eff) forms slightly anion-selective channels. Both proteins were partially sequenced. A multiple sequence alignment search within the known chromosome of C. efficiens demonstrated that it contains a gene that fits the partial amino acid sequence of PorH(C.eff). PorH(C.call) shows high homology to PorH(C.eff). PorH(C.eff) is encoded in the bacterial chromosome by a gene that is localized within the vicinity of the porA gene of C. efficiens. PorH(C.eff) has no signal sequence at the N terminus, which means that it is not exported by the Sec-secretion pathway. The structure of PorH in the cell wall of the corynebacteria is discussed.

A 2-year-old boy was found to have a 47,XXX karyotype. Restriction-fragment-length-polymorphism analysis showed that, of his three X chromosomes, one is of paternal and two are of maternal origin. The results of Y-DNA hybridization were reminiscent of those in XX males in two respects. First, hybridization to Southern transfers revealed the presence in this XXX male of sequences derived from the Y-chromosomal short arm. Second, in situ hybridization showed that this Y DNA was located on the tip of the X-chromosomal short arm. We conclude that this XXX male resulted from the coincidence of X-X nondisjunction during maternal meiosis and aberrant X-Y interchange either during or prior to paternal meiosis.

Previous studies have indicated the existence of common mechanisms regulating sleep and somatotropic activity. In the present study, we investigated the effects of prolonged treatment with a novel, orally active, growth hormone secretagogue (MK-677) on sleep quality in healthy young and older adults. Eight young subjects (18-30 years) followed a double-blind, placebo-controlled, three-period crossover design. Each subject participated in three 7-day treatment periods (with bedtime drug administration), presented in random (Latin square) order, and separated by at least 14 days. Doses were 5 and 25 mg MK-677 and matching placebo. Six older subjects, ages 65-71 years, each participated in two 14-day treatment periods (with bedtime drug administration) separated by a 14-day washout. Doses were 2 and 25 mg MK-677 during the first and second periods, respectively. Baseline sleep and hormonal data were obtained on the 2 days preceding the beginning of the first 14-day treatment period. In young subjects, high-dose MK-677 treatment resulted in an approximately 50% increase in the duration of stage IV and in a more than 20% increase in REM sleep as compared to placebo (p < 0.05). The frequency of deviations from normal sleep decreased from 42% under placebo to 8% under high-dose MK-677 (p < 0.03). In older adults, treatment with MK-677 was associated with a nearly 50% increase in REM sleep (p < 0.05) and a decrease in REM latency (p < 0.02). The frequency of deviations from normal sleep also decreased (p < 0.02). The present findings suggest that MK-677 may simultaneously improve sleep quality and correct the relative hyposomatotropism of senescence.

Calf strains are common injuries seen in primary care and sports medicine clinics. Differentiating strains of the gastrocnemius or soleus is important for treatment and prognosis. Simple clinical testing can assist in diagnosis and is aided by knowledge of the anatomy and common clinical presentation.

Functional capacity is an important component of risk assessment for major surgery. Doctors' clinical subjective assessment of patients' functional capacity has uncertain accuracy. We did a study to compare preoperative subjective assessment with alternative markers of fitness (cardiopulmonary exercise testing [CPET], scores on the Duke Activity Status Index [DASI] questionnaire, and serum N-terminal pro-B-type natriuretic peptide [NT pro-BNP] concentrations) for predicting death or complications after major elective non-cardiac surgery.

Opioid-induced constipation (OIC) is a common condition in older adults who may not be responsive to traditional laxative therapy. OIC is defined as new or worsening constipation symptoms that occur with initiation of or altering the dose of opioid analgesia. For adult patients with OIC and noncancer pain, we recommend considering nonpharmacologic interventions (eg, dietary measures, increased physical activity, and biofeedback training) and over-the-counter laxatives, followed by prescription opioid receptor antagonists (methylnaltrexone, naloxegol, and naldemedine) if traditional over-the-counter laxatives fail. Other options may include lubiprostone, linaclotide, plecanatide, and prucalopride; however, these are not indicated for OIC specifically or studied in older adults. Because of the complex nature of absorption, distribution, metabolism, and excretion in the aging population, all agents used to treat OIC must be evaluated individually and reevaluated as patients continue to age. This review will serve as a guide to managing OIC in older adults.

Pericarditis is the term for inflammatory involvement of the pericardium, which can be associated with pericardial effusion and myocardial involvement (perimyocarditis). Pericarditis can be present in the context of systemic inflammatory rheumatic diseases but can also constitute a distinct disease entity. Idiopathic recurrent pericarditis (IRP) describes relapsing conditions of pericarditis with an unknown cause, which show essential common features with autoinflammatory diseases. This article gives an overview of the frequency of pericarditis in systemic rheumatic diseases. Moreover, the clinical manifestations and pathophysiology of IRP are discussed. Finally, the therapeutic algorithms for acute and idiopathic pericarditis are explained.

As the medical community is increasingly offering transplantation to patients with increasing comorbidity burdens, the number of simultaneous heart-kidney (SHK) transplants is rising in the United States. How to determine eligibility for SHK transplant versus heart transplant alone is unknown. In this review, we situate this problem in the broader picture of organ shortage. We critically appraise available literature on outcomes in SHK versus heart transplant alone. We posit staged kidney-after-heart transplantation as a plausible alternative to SHK transplantation and review the pros and cons. Drawing lessons from the field of simultaneous liver-kidney transplant, we argue for an analogous policy for SHK transplant with standardized minimal eligibility criteria and a modified Safety Net provision. The new policy will serve as a starting point for comparing simultaneous versus staged approaches and refining the medical eligibility criteria for SHK.

Idiopathic antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV) are a group of diseases that are often difficult to diagnose due to the wide range of clinical manifestations. Notably, renal involvement is a serious organ complication, which usually requires intensive immunosuppressive therapy and is prone to recurrence. In recent years, there has been some progress regarding the understanding of the pathogenesis of the diseases. It has been shown that both cocaine and levamisole, which is a common adulterant of cocaine, can trigger the formation of ANCAs and lead to the corresponding symptoms. We report two cases of AAV with different renal manifestations associated with cocaine consumption. Furthermore, we performed a review of the literature to identify, characterize and describe histologically documented cases of renal involvement in AAV, related to cocaine abuse. Cocaine/levamisole-induced vasculitis may, therefore, mimic idiopathic AAV. Although the detection of ANCA and anti-PR3 (proteinase 3, PR3) as well as anti-MPO antibodies (myeloperoxidase, MPO) are the serological hallmark of idiopathic AAV, certain clinical- and antibody constellations should lead to consideration of illicit drugs as inductors of the disease. Especially in young patients, certain serologic constellations (e.g., PR3 and MPO double positivity, positive antinuclear antibodies, low complement level, and positive testing for antiphospholipid antibodies), skin involvement, musculoskeletal symptoms and hematologic (anemia, leukopenia) affections should prompt testing for cocaine and levamisole consumption via urine drug testing. Treatment includes both immunosuppressive approaches and drug cessation but is difficult since many patients continue cocaine consumption.

Mitochondria act as 'sinks' for Ca2+ signaling, with mitochondrial Ca2+ uptake linking physiological stimuli to increased ATP production. However, mitochondrial Ca2+ overload can induce a cellular catastrophe by opening of the mitochondrial permeability transition pore (mPTP). This pore is a large conductance pathway in the inner mitochondrial membrane that causes bioenergetic collapse and appears to represent a final common path to cell death in many diseases. The role of the mPTP as a determinant of disease outcome is best established in ischemia/reperfusion injury in the heart, brain, and kidney, and it is also implicated in neurodegenerative disorders and muscular dystrophies. As the probability of pore opening can be modulated by drugs, it represents a useful pharmacological target for translational research in drug discovery. Described in this unit is a protocol utilizing isolated mitochondria to quantify this phenomenon and to develop a high-throughput platform for phenotypic screens for Ca2+ dyshomeostasis. © 2019 The Authors.

There is conclusive evidence to demonstrate the role of omega-3 polyunsaturated fatty acids (n-3 PUFA) in human development and growth, vision, and cell membrane fluidity (membrane order). N-3 PUFA also contribute to human health maintenance through correction of arrhythmias, inhibition of platelet aggregation and prolongation of clotting time, lowering blood pressure, lowering serum triglycerides and plasma homocysteine, being antiinflammatory and immunomodulatory, being cardio-protective, increasing insulin sensitivity in Asians, and decreasing the risk of breast and colorectal cancers. This understanding of a wide spectrum of biological effects attributable to n-3 PUFA has been unsettled by a systematic review of randomized clinical intervention trials (RCTs) which has reported that n-3 PUFA have negligible or no effect on all-cause or cardiovascular mortality. Here, possible reasons for the inconsistencies in regard to n-3 PUFA and cardiovascular diseases, along with the implications for their broader biology, are considered.

Polyarteritis nodosa (PAN) is a rare systemic vasculitis affecting multiple organs. Current standard treatment includes the use of glucocorticoids and cyclophosphamide. Unfortunately, some patients do not respond to this treatment and other therapeutic options are needed. We present a case of a young male with refractory PAN and ongoing biopsy evidence of active vasculitis despite optimal standard therapies, who was successfully treated with interleukin-6 antagonist, tocilizumab. A 24-year-old male presented with severe immobilizing polyneuropathy and myalgias. Clinical features included fasciitis, tenosynovitis, early signs of polyneuropathy, and panniculitis, which were largely refractory to the standard therapies. The previous unsuccessful treatments included high-dose glucocorticoids, methotrexate, cyclophosphamide, rituximab, anakinra, and intravenous immunoglobulins. Magnetic resonance imaging showed signs of myositis, with muscle biopsy confirming the diagnosis of PAN. Rapid clinical improvement and sustained remission occurred after interleukin-6 inhibition with tocilizumab at increased dose of 800 mg every 4 weeks. The used search strategy identified 20 publications of which four articles were included for the further analysis. In total, we report the clinical outcome of five PAN cases from the literature and the present one. The present case and the systematic review of literature suggest that tocilizumab is a possible treatment option for, otherwise, refractory hepatitis B virus negative PAN. Randomized-controlled trials are required to evaluate the safety and efficacy of tocilizumab in PAN.

Video captioning, in essential, is a complex natural process, which is affected by various uncertainties stemming from video content, subjective judgment, and so on. In this paper, we build on the recent progress in using encoder-decoder framework for video captioning and address what we find to be a critical deficiency of the existing methods that most of the decoders propagate deterministic hidden states. Such complex uncertainty cannot be modeled efficiently by the deterministic models. In this paper, we propose a generative approach, referred to as multimodal stochastic recurrent neural networks (MS-RNNs), which models the uncertainty observed in the data using latent stochastic variables. Therefore, MS-RNN can improve the performance of video captioning and generate multiple sentences to describe a video considering different random factors. Specifically, a multimodal long short-term memory (LSTM) is first proposed to interact with both visual and textual features to capture a high-level representation. Then, a backward stochastic LSTM is proposed to support uncertainty propagation by introducing latent variables. Experimental results on the challenging data sets, microsoft video description and microsoft research video-to-text, show that our proposed MS-RNN approach outperforms the state-of-the-art video captioning benchmarks.

A panel of experts was convened by the Infectious Diseases Society of America (IDSA) and Society for Healthcare Epidemiology of America (SHEA) to update the 2010 clinical practice guideline on Clostridium difficile infection (CDI) in adults. The update, which has incorporated recommendations for children (following the adult recommendations for epidemiology, diagnosis, and treatment), includes significant changes in the management of this infection and reflects the evolving controversy over best methods for diagnosis. Clostridium difficile remains the most important cause of healthcare-associated diarrhea and has become the most commonly identified cause of healthcare-associated infection in adults in the United States. Moreover, C. difficile has established itself as an important community pathogen. Although the prevalence of the epidemic and virulent ribotype 027 strain has declined markedly along with overall CDI rates in parts of Europe, it remains one of the most commonly identified strains in the United States where it causes a sizable minority of CDIs, especially healthcare-associated CDIs. This guideline updates recommendations regarding epidemiology, diagnosis, treatment, infection prevention, and environmental management.

Several phenomena in contemporary perinatology create challenges for analyzing pregnancy outcomes. These include recent increases in iatrogenic delivery at late preterm and early term gestation, which are incongruent with the belief that stillbirth and neonatal death risks decrease exponentially with advancing gestational age. Perinatal epidemiologists have also puzzled over the paradox of intersecting birthweight-specific and gestational age-specific perinatal mortality curves for decades. For example, neonatal mortality rates among preterm infants of women who smoke are substantially lower than neonatal mortality rates among preterm infants of non-smoking women, whereas the reverse pattern occurs at term gestation. This mortality crossover is observed across several contrasts (for example, women with hypertensive disorders of pregnancy vs. normotensive women, older vs. younger women, twins vs. singletons) and outcomes (stillbirth, neonatal death, sudden infant death syndrome and cerebral palsy), and irrespective of how advancing "maturity" is defined (birthweight or gestational age). One approach proposed to address and explain these unexpected phenomena is the fetuses-at-risk model. This formulation involves a reconceptualization of the denominator for perinatal outcome rates from births to surviving fetuses. In this overview of the fetuses-at-risk model, we discuss the central tenets of the births-based and the fetuses-based formulations. We also describe the extension of the fetuses-at-risk approach to outcomes into and beyond the neonatal period and to a multivariable adaptation. Finally, we provide a substantive context by discussing biological mechanisms underlying the fetuses-at-risk model and contemporary obstetric phenomena that are better understood from that model than from one based on births.

Recent advances in functional neuroimaging have demonstrated novel potential for informing diagnosis and prognosis in the unresponsive wakeful syndrome and minimally conscious states. However, these technologies come with considerable expense and difficulty, limiting the possibility of wider clinical application in patients. Here, we show that high density electroencephalography, collected from 104 patients measured at rest, can provide valuable information about brain connectivity that correlates with behaviour and functional neuroimaging. Using graph theory, we visualize and quantify spectral connectivity estimated from electroencephalography as a dense brain network. Our findings demonstrate that key quantitative metrics of these networks correlate with the continuum of behavioural recovery in patients, ranging from those diagnosed as unresponsive, through those who have emerged from minimally conscious, to the fully conscious locked-in syndrome. In particular, a network metric indexing the presence of densely interconnected central hubs of connectivity discriminated behavioural consciousness with accuracy comparable to that achieved by expert assessment with positron emission tomography. We also show that this metric correlates strongly with brain metabolism. Further, with classification analysis, we predict the behavioural diagnosis, brain metabolism and 1-year clinical outcome of individual patients. Finally, we demonstrate that assessments of brain networks show robust connectivity in patients diagnosed as unresponsive by clinical consensus, but later rediagnosed as minimally conscious with the Coma Recovery Scale-Revised. Classification analysis of their brain network identified each of these misdiagnosed patients as minimally conscious, corroborating their behavioural diagnoses. If deployed at the bedside in the clinical context, such network measurements could complement systematic behavioural assessment and help reduce the high misdiagnosis rate reported in these patients. These metrics could also identify patients in whom further assessment is warranted using neuroimaging or conventional clinical evaluation. Finally, by providing objective characterization of states of consciousness, repeated assessments of network metrics could help track individual patients longitudinally, and also assess their neural responses to therapeutic and pharmacological interventions.

Background: Hypertriglyceridemia is a common condition in the United States and is often associated with other metabolic disturbances, including insulin resistance, metabolic syndrome, and a predominance of small dense LDL particles.Objective: The objective of this trial was to evaluate the effects of a combination of egg protein (Epro) and unsaturated fatty acids (UFAs) substituted for refined starches and added sugars on insulin sensitivity (primary outcome) and other cardiometabolic health markers in overweight or obese adults with elevated triglyceride (TG) concentrations.Methods: Subjects with elevated TG concentrations were given test foods prepared by using Epro powder (∼8% of energy) and vegetable oil (∼8% of energy; Epro and UFA condition) or test foods prepared by using refined starch and sugar (∼16% of energy; carbohydrate condition) in a randomized, double-blind, controlled-feeding, crossover trial (3 wk/condition, 2-wk washout). The Matsuda insulin sensitivity index (MISI), fasting lipids, and other cardiometabolic health markers were assessed at baseline and the end of each diet condition. Responses were compared by using repeated-measures ANCOVA.Results: Twenty-five participants [11 men, 14 women; mean ± SEM: age, 46.3 ± 2.4 y; body mass index (in kg/m[2]), 31.8 ± 1.0] with a median (interquartile range limits) fasting serum TG concentration of 173 mg/dL (159, 228 mg/dL) completed the trial. The MISI value increased 18.1% ± 8.7% from baseline during the Epro and UFA condition and decreased 5.7% ± 6.2% from baseline during the carbohydrate condition (P < 0.001). The disposition index increased 23.8% ± 20.8% during the Epro and UFA condition compared with a decrease of 16.3% ± 18.8% during carbohydrate (P = 0.042) and LDL peak particle size increased 0.12 nm (-0.12, 0.28 nm) with Epro and UFA compared with a decrease of 0.15 nm (-0.33, 0.12 nm) with carbohydrate (P = 0.019). TG and VLDL cholesterol concentrations were lowered by 18.5% (-35.7%, -6.9%) and 18.6% (-34.8%, -7.4%), respectively, after the Epro and UFA condition and by 2.5% (-13.4%, 17.0%) and 3.6% (-12.5%, 16.2%), respectively, after the carbohydrate diet condition (P < 0.002).Conclusions: The replacement of refined carbohydrates with a combination of Epro and UFA increased the MISI value and altered several markers of cardiometabolic health in overweight or obese adults with elevated TG concentrations. This trial was registered at clinicaltrials.gov as NCT02924558.

Organic sunscreens continue to enter the environment through people's daily consumption, and become a kind of emerging contaminants. The photochemical degradation of benzophenone-3 (BP-3) in water by UV/H2O2 process was investigated. Several factors, including the initial BP-3 concentration, H2O2 concentration, UV light intensity, coexisting cations and anions, humic acid and tert-butyl alcohol, were also discussed. The results showed that BP-3 degradation rate constant decreased with increasing initial BP-3 concentration, while increased with increasing H2O2 dosage and UV intensity. Coexisting anions could reduce the degradation rate, while coexisting ferric ions could stimulate the production of OH through Fenton-like reaction, further significantly accelerated BP-3 degradation process. The BP-3 degradation would be inhibited by humic acid or tert-butyl alcohol. The electrical energy per order (E(Eo)) values were also calculated to evaluate the cost of BP-3 degradation by UV/H2O2 process. The addition of ferric ions significantly reduced the value of E(Eo). The investigation of processing parameter could provide a reference for the practical engineering applications of benzophenone compounds removal by UV/H2O2 process.

Few studies investigated the effects of emotion regulation strategies on autonomic parameters in socially anxious individuals. We asked 99 socially anxious participants to give an impromptu speech in front of an audience in a virtual reality environment. In the anticipation phase, they practiced an emotion regulation strategy: negative functional reappraisal, acceptance, negative dysfunctional reappraisal. All strategies led to decreases in parasympathetic activity and increases in heart rate during anticipation. Parasympathetic activity remained low in the recovery phase, while heart rate increased, indicating a possible rebound effect of social performance. Exploratory moderation analysis revealed that for subjects with higher social anxiety, acceptance led to increased parasympathetic activity in the anticipation and recovery phases than negative functional reappraisal. Our results indicate that although globally parasympathetic reactivity seems to be a more general marker of simply attempting to regulate emotions, it could help distinguish between emotion regulation strategies for some participant subgroups.

A panel of national experts was convened by the Infectious Diseases Society of America (IDSA) to update the 2005 guidelines for the treatment of skin and soft tissue infections (SSTIs). The panel's recommendations were developed to be concordant with the recently published IDSA guidelines for the treatment of methicillin-resistant Staphylococcus aureus infections. The focus of this guideline is the diagnosis and appropriate treatment of diverse SSTIs ranging from minor superficial infections to life-threatening infections such as necrotizing fasciitis. In addition, because of an increasing number of immunocompromised hosts worldwide, the guideline addresses the wide array of SSTIs that occur in this population. These guidelines emphasize the importance of clinical skills in promptly diagnosing SSTIs, identifying the pathogen, and administering effective treatments in a timely fashion.

A Panel of International Experts was convened by the Infectious Diseases Society of America (IDSA) in collaboration with the European Society for Microbiology and Infectious Diseases (ESCMID) to update the 1999 Uncomplicated Urinary Tract Infection Guidelines by the IDSA. Co-sponsoring organizations include the American Congress of Obstetricians and Gynecologists, American Urological Association, Association of Medical Microbiology and Infectious Diseases-Canada, and the Society for Academic Emergency Medicine. The focus of this work is treatment of women with acute uncomplicated cystitis and pyelonephritis, diagnoses limited in these guidelines to premenopausal, non-pregnant women with no known urological abnormalities or co-morbidities. The issues of in vitro resistance prevalence and the ecological adverse effects of antimicrobial therapy (collateral damage) were considered as important factors in making optimal treatment choices and thus are reflected in the rankings of recommendations.

Evidence-based guidelines for managing patients with intra-abdominal infection were prepared by an Expert Panel of the Surgical Infection Society and the Infectious Diseases Society of America. These updated guidelines replace those previously published in 2002 and 2003. The guidelines are intended for treating patients who either have these infections or may be at risk for them. New information, based on publications from the period 2003-2008, is incorporated into this guideline document. The panel has also added recommendations for managing intra-abdominal infection in children, particularly where such management differs from that of adults; for appendicitis in patients of all ages; and for necrotizing enterocolitis in neonates.

Shigella sonnei UCN59, isolated during an outbreak of S. sonnei in January 2007, was resistant to azithromycin (MIC 64 mg/L). The isolate contained a plasmid-borne mph(A) gene encoding a macrolide 2 -phosphotransferase that inactivates macrolides. Emergence of the mph(A) gene in S. sonnei may limit usefulness of azithromycin for treatment of shigellosis.

Second-generation antipsychotic drugs (APDs), including aripiprazole, clozapine, olanzapine, risperidone, quetiapine, and ziprasidone dominate outpatient and inpatient clinical practice, having largely displaced the older neuroleptics. Modern APDs have relatively low risk for acute extrapyramidal syndromes characteristic of older neuroleptics, particularly acute dystonia and Parkinsonism, with variable risks of akathisia and the rare neuroleptic malignant syndrome. Anticipated reduction in risk of tardive dyskinesia (TD) is less well documented. Nearly 50 years after initial reports on TD, it is appropriate to reexamine the epidemiology of this potentially severe late adverse effect of long-term APD treatment in light of current research and practice. We compared recent estimates of incidence and prevalence of TD identified with some modern APDs to the epidemiology of TD in the earlier neuroleptic era. Such comparisons are confounded by complex modern APD regimens, uncommon exposure limited to a single modern APD, effects of previous exposure to typical neuroleptics, and neurological assessments that are rarely prospective or systematic. Available evidence suggests that the risk of TD may be declining, but longitudinal studies of patients never treated with traditional neuroleptics and exposed to only a single modern APD are required to quantify TD risks with specific drugs. Long-term use of APDs should continue to be based on research-supported indications, with regular specific examination for emerging TD.

A previous review of alternative treatments (Tx) of ADHD--those other than psychoactive medication and behavioral/psychosocial Tx--was supplemented with an additional literature search focused on adults with ADHD. Twenty-four alternative Tx were identified, ranging in scientific documentation from discrediting controlled studies through mere hypotheses to positive controlled double-blind clinical trials. Many of them are applicable only to a specific subgroup. Although oligoantigenic (few-foods) diets have convincing double-blind evidence of efficacy for a properly selected subgroup of children, they do not appear promising for adults. Enzyme-potentiated desensitization, relaxation/EMG biofeedback, and deleading also have controlled evidence of efficacy. Iron supplementation, magnesium supplementation, Chinese herbals, EEG biofeedback, massage, meditation, mirror feedback, channel-specific perceptual training, and vestibular stimulation all have promising prospective pilot data, many of these tests reasonably controlled. Single-vitamin megadosage has some intriguing pilot trial data. Zinc supplementation is hypothetically supported by systematic case-control data, but no systematic clinical trial. Laser acupuncture has promising unpublished pilot data and may be more applicable to adults than children. Essential fatty acid supplementation has promising systematic case-control data, but clinical trials are equivocal. RDA vitamin supplementation, non-Chinese herbals, homeopathic remedies, and antifungal therapy have no systematic data in ADHD. Megadose multivitamin combinations are probably ineffective for most patients and are possibly dangerous. Simple sugar restriction seems ineffective. Amino acid supplementation is mildly effective in the short term, but not beyond 2-3 months. Thyroid treatment is effective in the presence of documented thyroid abnormality. Some alternative Tx of ADHD are effective or probably effective, but mainly for certain patients. In some cases, they are the Tx of choice, and initial evaluation should consider the relevant etiologies. A few have failed to prove effective in controlled trials. Most need research to determine whether they are effective and/or to define the applicable subgroup. Some of them, although not safer than standard Tx, may be preferable for an etiologic subgroup.

A number of different chronic diseases affect the intrahepatic bile radicles or cholangioles. They include primary and secondary sclerosing cholangitis, primary biliary cirrhosis, chronic cholestatic drug jaundice, atresia, and carcinoma. Aetiological factors include infection, immunological changes, hormones, and congenital defects.Patients with chronic cholestasis have decreased bile salts in the intestinal contents and suffer from a bile salt deficiency syndrome. Failure to absorb dietary fat is managed by a low-fat diet and by medium-chain trigly-cerides which are absorbed in the absence of intestinal bile salts. Fat-soluble vitamin deficiencies are prevented by parenteral vitamins A, D, and K(1). Calcium absorption is defective, and improvement may follow intramuscular vitamin D, medium-chain triglycerides, a low-fat diet, and oral calcium supplements.In partial intestinal bile salt deficiency the anionic bile-salt-chelating resin cholestyramine controls pruritus though steatorrhoea increases. Pruritus associated with total lack of intestinal bile salts is managed by methyl-testosterone or norethandrolone, though the jaundice increases.
