Abstract
Background The consequences of cardiac arrest (CA) on the gastro-intestinal tract are poorly understood. We measured the incidence of ischemic injury in the upper gastro-intestinal tract after Out-of-hospital CA (OHCA) and determined the risk factors for and consequences of gastrointestinal ischemic injury according to its severity.
Methods Prospective, non-controlled, multicenter study in nine ICUs in France and Belgium conducted from November 1, 2014 to November 30, 2018. Included patients underwent an esophago-gastro-duodenoscopy 2 to 4 d after OHCA if still intubated and the presence of ischemic lesions of the upper gastro-intestinal tract was determined by a gastroenterologist. Lesions were a priori defined as severe if there was ulceration or necrosis and moderate if there was mucosal edema or erythema. We compared clinical and cardiac arrest characteristics of three groups of patients (no, moderate, and severe lesions) and identified variables associated with gastrointestinal ischemic injury using multivariate regression analysis. We also compared the outcomes (organ failure during ICU stay and neurological status at hospital discharge) of the three groups of patients. Results Among the 214 patients included in the analysis, 121 (57%, 95% CI 50–63%) had an upper gastrointestinal ischemic lesion, most frequently on the fundus. Ischemic lesions were severe in 55/121 (45%) patients. In multivariate regression, higher adrenaline dose during cardiopulmonary resuscitation (OR 1.25 per mg (1.08–1.46)) was independently associated with increased odds of severe upper gastrointestinal ischemic lesions; previous proton pump inhibitor use (OR 0.40 (0.14–1.00)) and serum bicarbonate on day 1 (OR 0.89 (0.81–0.97)) were associated with lower odds of ischemic lesions. Patients with severe lesions had a higher SOFA score during the ICU stay and worse neurological outcome at hospital discharge. Conclusions More than half of the patients successfully resuscitated from OHCA had upper gastrointestinal tract ischemic injury. Presence of ischemic lesions was independently associated with the amount of adrenaline used during resuscitation. Patients with severe lesions had higher organ failure scores during the ICU stay and a worse prognosis. Clinical Trial RegistrationNCT02349074.

Abstract
Abstract
Introduction
A decline in sleep quality and reduction in slow wave sleep (SWS) and slow wave activity (SWA) are common in older adults. Prior studies have shown that manipulating body temperature during sleep can increase SWS/SWA. The aim of this study was to determine the effects of manipulation of body temperatures during sleep, using a high heat capacity mattress, on SWS/SWA and heart rate variability in post-menopausal women.
Methods
Twenty-four healthy postmenopausal women between 40–75 years of age (mean age 62.4 ± 8.2 years, mean BMI 25.4 ± 3.5 kg/m2) were randomized in a single-blind, counterbalanced, cross-over manner to sleep on either a high heat capacity mattress (HHCM) or a low heat capacity mattress(LHCM) a week apart. Sleep was recorded using polysomnography during an 8-hour sleep opportunity. Core and peripheral temperatures were recorded using Equivital and ibutton respectively.
Results
In comparison to the LHCM, sleep on HHCM exhibited a selective increase in SWS (average increase in Stage N3 of 9.6 minutes (2.1%), p = 0.04) and in slow oscillatory activity (0.5-1Hz) in the first NREM/REM cycle (p=0.04). In addition, the HHCM induced a greater reduction in core body temperature (p=0.002), and delayed the increase in mattress surface temperature (maximal difference LHCM-HHCM: 4.66±0.17°C). Average heart rate was 2.7 beats/minute lower across the night on the HHCM compared to the LHCM (p=0.001).
Conclusion
The results of this study indicate that manipulation of body temperature during sleep may be a useful approach to enhance SWS sleep and cardiovascular function in postmenopausal women.

Abstract
Objectifs : Bien que quotidiennement géré par les infirmier(ière)s diplômé(e)s d’État (IDE) de réanimation, le sevrage des catécholamines a rarement été étudié. L’hypothèse de notre étude était que l’augmentation du nombre d’interventions menées sur la vitesse de perfusion des catécholamines permettait de raccourcir la durée d’administration de celles-ci.
Patients et méthodes : Il s’agissait d’une étude prospective observationnelle dans 21 réanimations. Tous les patients traités par vasopresseurs pendant la période d’étude ont été inclus. Le nombre d’interventions effectuées par l’IDE en charge du patient sur la vitesse d’administration des catécholamines était noté toutes les quatre heures. La posologie de catécholamines en cours ainsi que la pression artérielle moyenne (PAM) du patient étaient également relevées. Les facteurs influençant la rapidité du sevrage des catécholamines étaient également analysés.
Résultats : Nous avons inclus 226 patients dont l’âge moyen était de 65 ± 14 ans. La durée moyenne du traitement par catécholamines était de 71,6 (±81) heures. Le nombre d’interventions IDE par quatre heures était de 1,9 (±2,8) intervention. La durée du traitement par catécholamines était significativement moindre lorsque le nombre d’interventions augmentait (p = 0,04). L’existence d’un protocole spécifique à la gestion des catécholamines raccourcissait leur durée de sevrage. Un IGS2 élevé, une PAM élevée ainsi que la période diurne étaient associés à une augmentation du nombre des interventions IDE.
Conclusion : Le nombre d’interventions par les IDEs menées sur la perfusion de catécholamines était inversement lié à la durée du traitement par catécholamines. Des études complémentaires permettront d’évaluer l’impact de ces interventions sur le pronostic des patients.

Abstract
BACKGROUND To assess the impact of the incidental relocation of an intensive care unit (ICU) on the risk of colonizations/infections with Pseudomonas aeruginosa exhibiting OprD-mediated resistance to imipenem (PA-OprD). AIM The primary aim was to compare the proportion of PA-OprD among P. aeruginosa samples before and after an incidental relocation of the ICU. The role of tap water as a route of contamination for colonization/infection of patients with PA-OprD was assessed as a secondary aim. METHODS A single-centre, observational, before/after comparison study was conducted from October 2013 to October 2015. The ICU was relocated at the end of October 2014. All P. aeruginosa-positive samples isolated from patients hospitalized ≥48 h in the ICU were included. Tap water specimens were collected every three months in the ICU. PA-OprD strains isolated from patients and tap water were genotyped using pulse-field gel electrophoresis. FINDINGS A total of 139 clinical specimens of P. aeruginosa and 19 tap water samples were analysed. The proportion of PA-OprD strains decreased significantly from 31% to 7.7% after the relocation of the ICU (P = 0.004). All PA-OprD clinical specimens had a distinct genotype. Surprisingly, tap water was colonized with a single PA-OprD strain during both periods, but this single clone has never been isolated from clinical specimens. CONCLUSION Relocation of the ICU was associated with a marked decrease in P. aeruginosa strains resistant to imipenem. The polyclonal character of PA-OprD strains isolated from patients and the absence of tap-water-to-patient contamination highlight the complexity of the environmental impact on the endogenous colonization/infection with P. aeruginosa.

Abstract
PURPOSE Klinefelter's syndrome (KS) is associated with specific neurobehavioral features and personality traits. The aim of our study was to investigate fluid intelligence, personality traits and personality disorders (PD) and possible correlations with testosterone in a cohort of adult KS patients. METHODS We analyzed 58 adult KS patients with the classic 47, XXY karyotype. The Structured Clinical Interview for axis II disorders was used to assess DSM IV personality disorders. Personality traits were assessed using MMPI-2. Fluid intelligence was tested by using Raven's Standard Progressive Matrices (SPM) Test. Testosterone blood concentration was measured by CMIA. RESULTS PD prevalence was 31%. Four altered MMPI scales (Social Responsibility, Dominance, Ego Strength and Repression) were found in more than 40% of patients. Overcontrolled hostility and MacAndrew Alcoholism Scale-Revised scales were altered in the PD- group only. Biz-Odd Thinking and Post-Traumatic Stress Disorder scale were associated with the presence of personality disorder. The raw SPM score was 44 ± 10.8 without any significant correlation with testosterone. No significant difference in mean age, SPM raw score and MMPI score was observed between eugonadal, hypogonadal and treated patients. CONCLUSIONS Most KS patients had average fluid intelligence. PD prevalence was higher than in the general population. Testosterone was not correlated with fluid intelligence, personality traits or PD, but a reduction in marital distress was observed in treated patients. This could suggest that testosterone therapy can improve physical symptoms and this effect could also improve relationship abilities and wellness awareness.

Abstract
Background
Clinical features and outcomes of patients with spontaneous ilio-psoas hematoma (IPH) in intensive care units (ICUs) are poorly documented. The objectives of this study were to determine epidemiological, clinical, biological and management characteristics of ICU patients with IPH. Methods
We conducted a retrospective multicentric study in three French ICUs from January 2006 to December 2014. We included IPH diagnosed both at admission and during ICU stay. Surgery and embolization were available 24 h a day for each center, and therapeutic decisions were undertaken after pluridisciplinary discussion. All IPHs were diagnosed using CT scan. Results During this period, we identified 3.01 cases/1000 admissions. The mortality rate of the 77 included patients was 30 %. In multivariate analysis, we observed that mortality was independently associated with SAPS II (OR 1.1, 95 % CI [1.013–1.195], p = 0.02) and with the presence of hemorrhagic shock (OR 67.1, 95 % CI [2.6–1691], p = 0.01). We found IPH was related to anticoagulation therapy in 56 cases (72 %), with guideline-concordant reversal performed in 33 % of patients. We did not found any association between anticoagulant therapy type and outcome. Conclusion We found IPH is an infrequent disease, with a high mortality rate of 30 %, mostly related to anticoagulation therapy and usually affecting the elderly. Management of anticoagulation-related IPH includes a high rate of no reversal of 38 %.

Abstract
Infectious diseases remain a major public health issue in both developing and developed countries. For instance, there is still a high rate of morbidity and mortality due to seasonal influenza outbreaks and severe bacterial sepsis, despite major advances in their prevention and treatment. It is now clear that severe influenza and bacterial infections promote susceptibility for superinfections worsening the prognosis. Various immune defects acquired during severe infection may result in complex immunosuppression and may affect both innate and adaptive components. Some animal models of these common clinical situations have demonstrated the increased susceptibility of infected hosts to secondary infectious insult and allowed assessing the regulatory mechanisms. Such pathophysiological advances may help create new immunomodulatory therapeutics for infected patients exposed to severe secondary sepsis.

Abstract
AIMS Gut dysfunction is suspected to play a major role in the pathophysiology of post-resuscitation disease through an increase in intestinal permeability and endotoxin release. However this dysfunction often remains occult and is poorly investigated. The aim of this pilot study was to explore intestinal failure biomarkers in post-cardiac arrest patients and to correlate them with endotoxemia. METHODS Following resuscitation after cardiac arrest, 21 patients were prospectively studied. Urinary intestinal fatty acid-binding protein (IFABP), which marks intestinal permeability, plasma citrulline, which reflects the functional enterocyte mass, and whole blood endotoxin were measured at admission, days 1-3 and 6. We explored the kinetics of release and the relationship between IFABP, citrulline and endotoxin values. RESULTS IFABP was extremely high at admission and normalized at D3 (6668 pg/mL vs 39 pg/mL, p=0.01). Lowest median of citrulline (N=20-40 μmol/L) was attained at D2 (11 μmol/L at D2 vs 24 μmol/L at admission, p=0.01) and tended to normalize at D6 (21 μmol/L). During ICU stay, 86% of patients presented a detectable endotoxemia. Highest endotoxin level was positively correlated with highest IFABP level (R(2)=0.31, p=0.01) and was inversely correlated with lowest plasma citrulline levels (R(2)=0.55, p<0.001). Endotoxin levels increased between admission and D2 in patients with post-resuscitation shock, whereas it decreases in patients with no shock (median +0.33 EU vs -0.19 EU, p=0.03). Highest endotoxin level was positively correlated with D3 SOFA score (R(2)=0.45, p=0.004). CONCLUSION Biomarkers of intestinal injury are altered after cardiac arrest and are associated with endotoxemia. This could worsen post-resuscitation shock and organ failure.

Abstract
PURPOSE Septic shock induces a decrease in dendritic cells (DCs) that may contribute to sepsis-induced immunosuppression. We analyzed the time course of circulating DCs in patients with septic shock and its relation to susceptibility to intensive care unit (ICU)-acquired infections. METHODS We enrolled adult patients with septic shock (n = 43), non-septic shock (n = 29), and with sepsis without organ dysfunction (n = 16). Healthy controls (n = 16) served as reference. Blood samples were drawn on the day of shock (day 1), then after 3 and 7 days. Myeloid (mDC) and plasmacytoid (pDC) DCs were counted by flow cytometry. Cell surface HLA-DR expression was analyzed in both DC subsets. RESULTS At day 1, median mDC and pDC counts were dramatically lower in septic shock patients as compared to healthy controls (respectively, 835 mDCs and 178 pDCs/ml vs. 19,342 mDCs and 6,169 pDCs/ml; P < 0.0001) but also to non-septic shock and sepsis patients (P < 0.0001). HLA-DR expression was decreased in both mDCs and pDCS within the septic shock group as compared to healthy controls. DC depletion was sustained for at least 7 days in septic shock patients. Among them, 10/43 developed ICU-acquired infections after a median of 9 [7.5-11] days. At day 7, mDC counts increased in patients devoid of secondary infections, whereas they remained low in those who subsequently developed ICU-acquired infections. CONCLUSION Septic shock is associated with profound and sustained depletion of circulating DCs. The persistence of low mDC counts is associated with the development of ICU-acquired infections, suggesting that DC depletion is a functional feature of sepsis-induced immunosuppression.

Abstract
We used multimodal magnetic resonance (MR) techniques [brain diffusion-weighted magnetic resonance imaging, diffusion-weighted imaging (DWI), proton MR spectroscopy (MRS), 1H-MRS; and skeletal muscle phosphorous MRS, 31P-MRS] to investigate interictal brain microstructural changes and tissue energy metabolism in four women with genetically determined familial hemiplegic migraine type 2 (FHM2), belonging to two unrelated families, compared with 10 healthy women. Brain DWI revealed a significant increase of the apparent diffusion coefficient median values in the vermis and cerebellar hemispheres of FHM2 patients, preceding in two subjects the onset of interictal cerebellar deficits. 31P-MRS revealed defective energy metabolism in skeletal muscle of FHM2 patients, while brain 1H-MRS showed a mild pathological increase in lactate in the lateral ventricles of one patient and a mild reduction of cortical N-acetyl-aspartate to creatine ratio in another one. Our MRS results showed that a multisystem energy metabolism defect in FHM2 is associated with microstructural cerebellar changes detected by DWI, even before the onset of cerebellar symptoms.

Abstract
OBJECTIVE To test for the autonomic neuropathy in systemic sclerosis (SSc) using cardiovascular reflex evaluation including the "cold face test", which elicits forehead cold receptors (C-fibres). These tests examine the induced bradycardia-hypertensive response and the integrity of nociceptive afferent and parasympathetic-sympathetic efferent pathways. METHODS Twelve SSc patients were studied; including 5 with the limited cutaneous (lcSSc) involvement, and 7 with diffuse cutaneous involvement (dcSSc). All patients were matched with healthy controls. We performed cardiovascular autonomic tests (tilt-test, Valsalva manoeuver, deep breathing, sustained handgrip and cold face) with continuous monitoring of beat-to-beat blood pressure (BP) and heart rate (HR). Baroreceptor sensitivity index (BRSI) and power spectral analysis (PSA) of heart rate variability (HRV) were also evaluated. RESULTS SSc patients showed a statistically significant higher HR at rest (p<0.01), a lower increase of diastolic BP during tilt test (p<0.01). They had suboptimal hypertensive and bradycardic response to the cold face test (Systolic BP: p<0.05; Diastolic BP: p<0.01; HR: p=0.08). The Valsalva manoeuver, deep breathing, isometric handgrip, BRSI and PSA of HRV results were within normal limits in the majority of SSc patients. CONCLUSION In this group of SSc patients cardiovascular reflexes were normal, whereas the cold face test which acts through cutaneous nociceptive sensory fibres was abnormal in almost all patients. These results suggest that insufficiency of epidermal small fibres (C-fibres) is involved in SSc.

Abstract
We applied the recent International Headache Society (IHS) criteria for headache related to spontaneous intracranial hypotension (SIH) to 90 consecutive patients with a final diagnosis of SIH confirmed by cerebral magnetic resonance imaging with contrast. Orthostatic headache (developing within 2 h of standing or sitting up) was present in 67 patients (75%) but appeared within 15 min after standing or sitting—as required by point A of the criteria—in only 53 (59%). Forty-four (49%) patients did not satisfy point A, including 22 (24%) with non-orthostatic headache and 14 (16%) with headache developing ≥ 15 min after standing or sitting up; 80 (89%) did not satisfy point D. Only three (3%) patients had headache fully satisfying the IHS criteria. These findings indicate that the current IHS criteria do not capture most patients with SIH-associated headache. Excluding the requirement for response to epidural blood patch (criterion D) and considering headaches appearing within 2 h of sitting or standing up would capture more patients.

Abstract
The objective of this study was to determine the cardiovascular effects of chronic stimulation of the posterior hypothalamic area (PHA) in cluster headache (CH) patients. Systolic and diastolic blood pressure (SBP, DBP), cardiac output, total peripheral resistance (TPR), heart rate (HR) and breathing were monitored at supine rest and during head-up tilt test (HUTT), Valsalva manoeuvre, deep breathing, cold face test and isometric handgrip in eight drug-resistant chronic CH patients who underwent monolateral electrode implantation in the PHA for therapeutic purposes. Autoregressive power spectral analysis (PSA) of HR variability (HRV) was calculated at rest and during HUTT. Each subject was studied before surgery (condition A) and after chronic deep brain stimulation (DBS) of PHA (condition B). Baseline SBP, DBP, HR and cardiovascular reflexes were normal and similar in both conditions. With respect to condition A, DBP, TPR and the LF/HF obtained from the PSA of HRV were significantly (P < 0.05) increased during HUTT in condition B. In conclusion, chronic DBS of the PHA in chronic CH patients is associated with an enhanced sympathoexcitatory drive on the cardiovascular system during HUTT.

Abstract
The objective of this study was to evaluate how the criteria of the second edition of the International Classification of Headache Disorders (ICHD-II) and the revised criteria fit a sample of patients with chronic daily headache (CDH). One hundred and five patients with CDH in a tertiary headache centre were included. Headache was assessed using a semi-structured interview. Patients were classified according to the ICHD-II and to the new appendix criteria of the ICHD. Using the ICHDII, 91% of patients received a combination of diagnoses and 76% received only a probable diagnosis: 47% had probable chronic migraine (CM) with probable medication overuse headache (MOH), 28% had probable chronic tension-type headache (CTTH) with probable MOH, 20% had CTTH and 3.8% had CM. Using the new appendix criteria, 88.5% of patients required one diagnosis. Seventy-six percent of patients were classified as MOH, 17% had CTTH and 6.7% had CM. The classification of CDH remains controversial. Alternative criteria for CM with and without medication overuse are discussed.

Abstract
Transthyretin (TTR) amyloidosis is a form of systemic amyloidosis caused by an amyloidogenetic TTR variant. The most common mutant forms of TTR are mainly produced by the liver and therefore orthotopic liver transplantation (OLT) is currently accepted as the only known curative treatment. We describe the clinical and pathological features of a patient with TTR variant (gly53glu) with TTR amyloid infiltration of the leptomeningeal vessels in whom fatal cerebral haemorrhage occurred two months after OLT, soon after severe viral pneumonia.

Abstract
Headache is a common Emergency Department (ED) problem accounting for 1.7%-4.5% of patients every year. The main aim in the ED is to differentiate between primary and secondary headache. Although secondary headache represents the lowest percentage (20%) of ED patients presenting with headache, it can be life threatening. Patients with primary headache require a follow-up programme on discharge from the ED with a specialist headache clinic taking responsibility for these patients. This procedure was applied at Ravenna Hospital ED for 2 years and recorded (unpublished data) a reduction in the number of repeat visits to the ED for headache and the number of inappropriate admissions for headache (DRG 25).

Abstract
Chronic daily headache (CDH) is a major clinical concern, although it is still plagued by difficulties with classification and definitions. CDH usually evolves from an episodic headache, mainly migraine. Drug overuse and other somatic or psychological traits are considered risk factors for CDH. The neurobiology underlying this clinical evolution is incompletely understood. There is evidence of a progressive dysfunction of central pain systems in some individuals probably genetically predisposed.

Abstract
Prophylactic treatment is mainly intended to reduce the frequency of migraine attacks, enhance response to acute medications, improve patient function and reduce disability. Sufficient evidence and consensus exist to recommend propranolol, timolol, amitriptyline, pizotifen, divalproex, sodium valproate and topiramate as first line agents for migraine prevention. These drugs can halve the frequency of attacks in 50% of patients. The anticipated benefit must be weighed against the adverse effects associated with each agent in determining the optimal preventive regimen for individual patients considering any comorbid conditions that are often present. The decision to treat and the choice of prophylactic drug must be taken with the patient. It is important to balance expectations and therapeutic realities for each particular drug. Recent data on the effect of prophylactic treatment on trigeminovascular activation and on cortical spreading depression emphasise the importance of developing research on migraine-preventive drugs.

Abstract
INTRODUCTION Whipple disease is a multisystem infectious disease caused by Tropheryma whipplei. We report a case in which an initial diagnosis of sarcoidosis was changed to Whipple disease endocarditis. CASE Based on clinical, radiographic, endoscopic and histologic findings, this 61-year-old man was diagnosed with sarcoidosis. Initial response to corticotherapy was good, but the patient required 35 mg of prednisone daily. The subsequent onset of clinical and laboratory signs of inflammation cast doubt on the diagnosis. After cardiac ultrasound revealed a mass 1 cm in diameter on the mitral valve, apparently vegetation, we diagnosed culture-negative infective endocarditis and ruled out most possible causes. PCR of a duodenal biopsy sample showed Tropheryma whipplei, thus confirming the diagnosis of Whipple disease, despite normal histological findings. After 3 weeks of intravenous gentamicin and amoxicillin treatment, oral cotrimoxazole was substituted. Follow-up transesophageal ultrasound showed no mitral vegetation. The patient, still under cotrimoxazole, has been off prednisone for 13 months and is completely asymptomatic. CONCLUSION This case is an illustration of the difficulty in distinguishing Whipple disease from sarcoidosis in practice and of the importance of that distinction.

Abstract
Spontaneous intracranial hypotension (SIH) is a syndrome of low cerebrospinal fluid (CSF) pressure characterised by postural headaches in patients without any history of dural puncture or penetrating trauma. Described by Schaltenbrand in 1938, SIH is thought to result from an occult CSF leak resulting in decreased CSF volume and, consequently, in low CSF pressure. Magnetic resonance imaging of the head and spine has improved the diagnosis of the syndrome showing peculiar radiographic abnormalities including diffuse pachymeningeal enhancement, subdural fluid collections and downward displacement of the cerebral structures. Treatment of SIH headache should start with conservative, non-invasive therapies while epidural blood patch has emerged as the treatment of choice for those symptomatic patients who have failed medical noninvasive approaches.

Abstract
Headache is generally regarded as a symptom of high blood pressure in spite of conflicting opinions on the association of headache and arterial hypertension. Most studies have shown that mild chronic hypertension and headache are not associated and this demonstration needs to be implemented in clinical practice. Whether moderate hypertension predisposes to headache remains controversial, but there is little evidence that it does. Headaches caused by significant disturbances in arterial pressure are included in the section "Headache attributed to a disorders of homeostasis" (code 10.3) of the 2nd edition of the International Classification of Headache disorders.

Abstract
A worker ant preserved with microscopic detail has been discovered in Turonian-aged New Jersey amber [ca. 92 mega-annum (Ma)]. The apex of the gaster has an acidopore and, thus, allows definitive assignment of the fossil to the large extant subfamily Formicinae, members of which use a defensive spray of formic acid. This specimen is the only Cretaceous record of the subfamily, and only two other fossil ants are known from the Cretaceous that unequivocally belong to an extant subfamily (Brownimecia and Canapone of the Ponerinae, in New Jersey and Canadian amber, respectively). In lieu of a cladogram of formicine genera, generalized morphology of this fossil suggests a basal position in the subfamily. Formicinae and Ponerinae in the mid Cretaceous indicate divergence of basal lineages of ants near the Albian (ca. 105-110 Ma) when they presumably diverged from the Sphecomyrminae. Sphecomyrmines are the plesiomorphic sister group to all other ants, or they are a paraphyletic stem group ancestral to all other ants-they apparently became extinct in the Late Cretaceous. Ant abundance in major deposits of Cretaceous and Tertiary insects indicates that they did not become common and presumably dominant in terrestrial ecosystems until the Eocene (ca. 45 Ma). It is at this time that modern genera that form very large colonies (at least 10,000 individuals) first appear. During the Cretaceous, eusocial termites, bees, and vespid wasps also first appear-they show a similar pattern of diversification and proliferation in the Tertiary. The Cretaceous ants have further implications for interpreting distributions of modern ants.

Abstract
Prescriptive authority for the advanced practice psychiatric nurse (APPN) is accompanied by the following advantages: expanded treatment repertoire, increased marketability due to the practicality of having one provider for psychotherapy and pharmacotherapy, and increased collaboration with colleagues. The disadvantages associated with prescriptive authority include: increased professional responsibility and associated liability, labor intensity due to continuing educational demands, medical record documentation, and time-consuming dialogues with referring clinicians. A preexisting relationship between the APPN and the psychiatrist that is based on mutual respect and similarities in treatment philosophies and ethical issues positively influence outcomes.

Abstract
Two species of fossil mushrooms that are similar to extant Tricholomataceae are described from Cretaceous and Miocene ambers. Archaeomarasmius leggetti gen. et sp. nov., from mid-Cretaceous amber of New Jersey, resembles the extant genera Marasmius and Marasmiellus. Two fruiting bodies of Archaeomarasmius were found. One consists of a complete pileus with stipe, and the other consists of a fragment of a pileus. The latter was accidentally exposed, and zxsubsequently was used for molecular systematics studies (attempts to amplify ribosomal DNA were unsuccessful) and electron microscopy. The spores are smooth and broadly elliptic with a distinct hilar appendage. Protomycena electra gen. et sp. nov., which is represented by a single complete fruiting body from Miocene amber of the Dominican Republic, is similar to the extant genus Mycena. Based on comparison to extant Marasmieae and Myceneae, Archaeomarasmius and Protomycena were probably saprophytes of leaf litter or wood debris. The poor phylogenetic resolution for extant homobasidiomycetes limits the inferences about divergence times of homobasidiomycete clades that can be drawn from Archaeomarasmius and Protomycena. The ages of these fossils lend support to hypotheses that the cosmopolitan distributions of certain mushroom taxa could be due to fragmentation of ancestral ranges via continental drift. Anatomical and molecular studies have suggested that there has been extensive convergence and parallelism in the evolution of homobasidiomycete fruiting body form. Nevertheless, the striking similarity of these fossils to extant forms suggests that in certain lineages homobasidiomycete macroevolution has also involved long periods during which there has been little morphological change.

Abstract
The verification of DNA sequences obtained from very old tissue sources as indeed ancient is a major point of discussion in the ancient DNA field. Proper controls and the use of the phylogenetic approach are the general methods employed for verification of the ancient DNA. Most studies have reported the recovery of extremely small amounts of nucleic acids which are sheared into rather small fragments. In addition, problems such as 'PCR jumping' can produce spurious sequence information. These observations suggest that random amplification techniques and the development of primers for highly informative but short target regions are essential for the further development of the ancient DNA field.
