The presentation of hypoactive sexual desire disorder in premenopausal women.

INTRODUCTION Little is known about the clinical presentation of hypoactive sexual desire disorder (HSDD) in premenopausal women or their perceptions of sexual problems. AIM Describe characteristics of premenopausal women with clinically diagnosed acquired, generalized HSDD, and investigate factors perceived to contribute to desire problems. METHODS Cross-sectional analysis of baseline data from premenopausal women with clinically diagnosed and confirmed HSDD enrolled during the first year of the HSDD Registry for Women (N=400). MAIN OUTCOME MEASURES Relationship, demographic, and clinical characteristics were assessed by clinician's medical history review and self-administered questionnaire. Sexual desire function was measured by the validated Female Sexual Function Index (FSFI). RESULTS Over 85% of women cited multiple factors that contributed to ongoing decreased desire (mean 2.9± 2.3 factors, range 0-12). Most commonly cited contributing factors were "stress or fatigue" (60.0%), "dissatisfaction with my physical appearance" (40.8%), and other sexual difficulties (e.g., inability to reach orgasm) (33.5%). Exploratory analyses of the FSFI score confirmed that self-image (P=0.002) and other sexual problems (P<0.001) were significantly associated with decreased desire. Almost all (96%) participants were currently in a partner relationship. Antidepressant medication was currently used by 18.0% of women, hormonal contraceptives by 28.5%, and hormonal medications (for noncontraceptive reasons) by 7.3%. Physical functioning was consistent with general population norms (SF-36 mean±standard deviation, 53.3±7.6 vs. norm of 50±10), while overall mental functioning was slightly lower (SF-36, 44.7±10.6). CONCLUSIONS Within this sample of premenopausal women with clinically diagnosed HSDD, decreased sexual desire was associated with multiple factors, including poor self-image and stress or fatigue. Clinicians presented with premenopausal women expressing sexual desire problems should assess patients' perceptions of their condition to develop a comprehensive, patient-oriented management plan. Therapy may need to address issues with low self-esteem and mood and offer practical coping mechanisms for stress and fatigue.
Influence of warming on soil water potential controls seedling mortality in perennial but not annual species in a temperate grassland.

In a water-limited system, the following hypotheses are proposed: warming will increase seedling mortality; elevated atmospheric CO2 will reduce seedling mortality by reducing transpiration, thereby increasing soil water availability; and longevity (i.e. whether a species is annual or perennial) will affect the response of a species to global changes. Here, these three hypotheses are tested by assessing the impact of elevated CO2 (550 micromol mol(-1) and warming (+2 degrees C) on seedling emergence, survivorship and establishment in an Australian temperate grassland from autumn 2004 to autumn 2007. Warming impacts on seedling survivorship were dependent upon species longevity. Warming reduced seedling survivorship of perennials through its effects on soil water potential but the seedling survivorship of annuals was reduced to a greater extent than could be accounted for by treatment effects on soil water potential. Elevated CO2 did not significantly affect seedling survivorship in annuals or perennials. These results show that warming will alter recruitment of perennial species by changing soil water potential but will reduce recruitment of annual species independent of any effects on soil moisture. The results also show that exposure to elevated CO2 does not make seedlings more resistant to dry soils.
Thyroglobulin measurements in fine‐needle aspiration cytology of lymph nodes for the detection of metastatic papillary thyroid carcinoma

Ultrasound‐guided fine‐needle aspiration (US‐FNA) cytology is a commonly used method in the surveillance of suspicious lymph nodes (LNs) in patients with papillary thyroid carcinoma (PTC). The measurement of thyroglobulin (Tg) levels in LNs during FNA has been suggested to improve the diagnosis. In the current study, the use of US‐FNA‐Tg in LNs that were suspicious for metastatic PTC was investigated.
Indicators of conformance with guidelines of schizophrenia treatment in mental health services.

OBJECTIVE The aim of this study was to develop indicators of conformance in clinical practice with guidelines for care in schizophrenia. Recommended guidelines rarely apply to all patients and need to allow for social ability, family context, and phase of the disorder. These indicators were therefore devised for tailoring to patient characteristics and allowing for factors that may justify the lack of adherence to clinical guidelines. METHODS A team of senior clinicians and methodologists reviewed three clinical guidelines (from the Schizophrenia Patient Outcomes Research Team, McEvoy and colleagues, and the National Institute for Health and Clinical Excellence) and defined criteria for their operationalization into clinical indicators. For each indicator, the team defined criteria for eligibility (requirements to be met to qualify for evaluation), conformance (criteria to be satisfied to comply with each recommendation), and moderators (factors that could justify the lack of application of a given recommendation). These indicators were tested with a random sample of 807 patients with schizophrenia or schizoaffective disorders in outpatient facilities, long-term residential facilities, and hospital units for acute care in the Piedmont region of Italy. RESULTS A set of 15 indicators was derived, nine concerning pharmacological treatment and six for general care and psychosocial rehabilitation. Moderators such as patient or family refusal of antipsychotic treatment and the patient's level of disability helped to justify a considerable proportion of nonconformant care. CONCLUSIONS The indicators developed are a simple and useful tool to monitor the conformance of care with recommended practices and to identify areas needing improvement.
Gene products of McDonough feline sarcoma virus have an in vitro-associated protein kinase that phosphorylates tyrosine residues: lack of detection of this enzymatic activity in vivo

The primary translational product of the McDonough (SM) strain of feline sarcoma virus (FeSV) is a 180,000-dalton molecule, SM P180, that contains the p15-p12-p30 region of the FeLV gag gene-coded precursor protein and a sarcoma virus-specific polypeptide. In addition, cells transformed by SM-FeSV express a 120,000-dalton molecule, SM P120, that is highly related to the non-helper virus domain of SM P180. Both SM-FeSV gene products were found to be intimately associated with the membrane fraction of SM-FeSV-transformed cells. Immunoprecipitates containing SM P180 and SM P120 exhibited a protein kinase activity capable of phosphorylating tyrosine residues of both viral gene products but not immune immunoglobulin G molecules. By independently immunoprecipitating each of the two SM-FeSV proteins we found that most of the tyrosine-specific phosphorylating activity was associated with the SM P120 molecule. In vivo analysis of 32P-labeled SM P180 and SM P120 revealed their phosphoprotein nature; however, both molecules exhibited low levels of phosphorylation and did not contain phosphotyrosine residues. Finally, we did not detect any significant elevation in the levels of phosphotyrosine in the protein fraction of SM-FeSV transformants. Thus, if SM-FeSV were to induce malignant transformation by a mechanism involving phosphorylation of tyrosine residues, the viral gene products must interact with a small subset of cellular proteins that do not represent a significant fraction of the total cellular protein content.
The Natural Biotic Environment of Caenorhabditis elegans

Organisms evolve in response to their natural environment. Consideration of natural ecological parameters are thus of key importance for our understanding of an organism’s biology. Curiously, the natural ecology of the model species Caenorhabditis elegans has long been neglected, even though this nematode has become one of the most intensively studied models in biological research. This lack of interest changed ∼10 yr ago. Since then, an increasing number of studies have focused on the nematode’s natural ecology. Yet many unknowns still remain. Here, we provide an overview of the currently available information on the natural environment of C. elegans. We focus on the biotic environment, which is usually less predictable and thus can create high selective constraints that are likely to have had a strong impact on C. elegans evolution. This nematode is particularly abundant in microbe-rich environments, especially rotting plant matter such as decomposing fruits and stems. In this environment, it is part of a complex interaction network, which is particularly shaped by a species-rich microbial community. These microbes can be food, part of a beneficial gut microbiome, parasites and pathogens, and possibly competitors. C. elegans is additionally confronted with predators; it interacts with vector organisms that facilitate dispersal to new habitats, and also with competitors for similar food environments, including competitors from congeneric and also the same species. Full appreciation of this nematode’s biology warrants further exploration of its natural environment and subsequent integration of this information into the well-established laboratory-based research approaches.
Arginine supplementation prevents necrotizing enterocolitis in the premature infant.

OBJECTIVES To determine whether supplementation with L -arginine reduces the incidence of all stages of necrotizing enterocolitis (NEC) in premature infants with birth weight < or =1250 g and gestational age < or =32 weeks. STUDY DESIGN In a randomized, double-blind, placebo-controlled study, 152 premature infants were prospectively, randomly assigned to receive either supplemental L -arginine (1.5 mmol/kg per day; n =75 [group A]) or placebo (control group; n = 77 [group B]) with oral feeds/parenteral nutrition during the first 28 days of life. Nutrient intake, plasma ammonia, arginine, and amino acid concentrations were measured in all infants at days 3, 14, and 28 and at the time of diagnosis of NEC. RESULTS NEC developed in 5 infants in group A compared with 21 infants in group B (P <.001). Arginine intake and plasma arginine concentrations were similar in both groups at study entry and (as expected) increased in group A at days 14 and 28. Plasma arginine concentrations were lower in both groups at time of diagnosis of NEC. No significant differences in maternal and neonatal demographics, nutrient intake, plasma ammonia and total and essential amino acid concentrations were present between the two groups. CONCLUSIONS Arginine supplementation (1.5 mmol/kg per day) in premature infants reduces the incidence of all stages of NEC.
An Artificial Intelligence Framework for On-Line Transient Stability Assessment of Power Systems

Transient stability assessment (TSA) of a power system pursues a twofold objective: first to appraise the system's capability to withstand major contingencies, and second to suggest remedial actions, i.e. means to enhance this capability, whenever needed. The first objective is the concern of analysis, the second is a matter of control. For the time being, the on-line TSA is still a totally open question. Indeed, none of the existing two broad classes of methods (the time domain and the direct methods) are able to meet the on-line requirements of the analysis aspects, nor are they in the least appropriate to tackle control aspects. The methodology we are introducing aims at solving the above stated on-line problem by making use of decision rules, preconstructed off-line. To this end, an inductive inference method is developed, able to provide decision rules in the form of binary trees expressing relationships between static, pre-fault operating conditions of a power system and its robustness to withstand assumed disturbances. This paper concentrates on this latter problem, which is the most difficult task, and also the kernel of the overall methodology. The proposed inductive inference (II) method pertains to a particular family of Machine Learning from examples. It derives from ID3 by Quinlan [1], tailored to our problem, where the examples are provided by numeric (load flow and stability) programs [2, 3]. According to the method, a decision tree (DT) is built on the basis of a preanalyzed learning set (LS), composed of states or operating points (OPs).
Impact of ABCB1 and CYP2D6 polymorphisms on tamoxifen treatment outcomes and adverse events in breast cancer patients.

PURPOSE This study was designed to evaluate the effect of CYP2D6 and ABCB1 polymorphisms and co-medication on the outcomes and adverse events (AEs) of tamoxifen therapy. METHODS In total, 258 women (187 postmenopausal and 71 premenopausal) with hormone positive breast carcinoma were retrospectively evaluated. CYP2D6 polymorphisms were evaluated with AmpliChip (Roche), and polymorphisms of ATP-binding cassettes B1 (P-glycoprotein) (ABCB1) rs2032582 and rs1045642 with restriction fragment length polymorphisms polymerase chain reaction (RFLP-PCR). RESULTS CYP2D6 polymorphisms or co-medication affecting CYP2D6 activity demonstrated no statistically significant effect on the efficacy of tamoxifen therapy or AE incidence. There was only a trend towards shortening the time to event (TTE) in CYP2D6-poor metabolisers. ABCB1 polymorphism rs2032582 was not associated with clinical outcomes, while a trend towards an increase in TTE, in variant allele carriers, was noted. The ABCB1 polymorphism rs1045642 demonstrated statistical significance, albeit only in premenopausal patients, i.e. the effect of two variant alleles on the TTE extension was demonstrated only in the premenopausal group (p=0.0012, HR 0.69; 95% CI 0.21-2.31), and statistical significance (p=0.0106) only for gynaecological/vasomotor AEs (p=0.0221, HR=1.0588), with no evidence of any influence on the incidence and onset of venous complications (i.e. deep venous thrombosis or pulmonary embolism). CONCLUSIONS Although no conclusive statistical association between the examined polymorphisms and the outcome or incidence of AEs in tamoxifen therapy was found, the impact of ABCB1 polymorphisms warrants further research. The importance of finding predictive pharmacogenomic biomarkers is a major challenge for individualization and pharmaco-economic rationalization of therapy. The latest international guidelines support this notion.
Effect of the Different Implant Protocols on Peri-Implant Bone: A 6-Month Prospective Study in Beagle Dogs

Objective To compare the effects of different implant placement and loading protocols on the marginal bone loss (MBL) in beagles by intraoral radiography. Methods and materials 61 dental implants were inserted on 9 beagle dogs at bilateral lower posteriors according to 8 different protocols: immediate implant placement and immediate loading for 3 months (IIP + IL3) or 6 months (IIP + IL6) and unloading (IIP + UL), immediate implant placement and delayed loading for 3 months (IIP + DL3) or 6 months (IIP + DL6), delayed implant placement and immediate loading for 3 months (DIP + IL3) or delayed loading for 3 months (DIP + DL3) and unloading (DIP + UL). Intraoral radiography was performed to analyze the MBL during each surgery, before and after the implant placement and at 3-month intervals after the procedure. Results In total, 57 samples were included. There was less MBL (p<0.05) in the IIP + IL3 group (1.22 ± 0.63 mm) compared to the DIP + IL3 group (1.89 ± 0.9 mm). The longer the loading time, the more bone loss appeared in the IIP + IL group; however, the results were reversed in the IIP + DL group. The MBL during the latter 3-month period was dramatically decreased compared to the former 3-month period in the IIP + DL3 group (p<0.05). Conclusions The IIP + IL group seems superior to the DL protocol and the MBL changed significantly during the first three months and thereafter became stable.
Endocytosis of Oxidized Low Density Lipoprotein through Scavenger Receptor CD36 Utilizes a Lipid Raft Pathway That Does Not Require Caveolin-1*

The scavenger receptor CD36 binds a diverse array of ligands, including thrombospondin-1, oxidized low density lipoprotein (OxLDL), fatty acids, anionic phospholipids, and apoptotic cells. CD36 has been reported to be present in lipid rafts/caveolae, but little is known about the membrane trafficking of this protein at baseline or following ligand binding. Here, we determined that expression of CD36 in Chinese hamster ovary (CHO) cells and endogenous expression of CD36 in C32 cells led to a homogeneous distribution of the protein on the plasma membrane, as judged by confocal fluorescence microscopy. This homogeneous pattern was observed both by anti-CD36 antibody staining and by live cell imaging of CHO cells expressing a chimeric CD36-green fluorescent protein construct. In contrast, caveolin-1 displayed its usual punctate surface distribution. Correspondingly, dual labeling of CD36 and caveolin-1 showed essentially no overlap, neither by immunofluorescence light microscopy nor by immunogold electron microscopy. Furthermore, isolation of lipid rafts by sucrose gradient ultracentrifugation of cold Triton X-100 cell lysates yielded both CD36 and caveolin-1, but immunoprecipitates of caveolin-1 did not contain CD36. Binding of Ox-LDL led to internalization of CD36 and OxLDL into endosomal structures that did not contain caveolin-1 or transferrin but that co-internalized the glycosyl-phosphatidylinositol-anchored protein decay accelerating factor, a lipid raft protein. Furthermore, expression of CD36 in the caveolin-1-negative KB cell line is sufficient for OxLDL-induced internalization of CD36, indicating that caveolin-1 is not required for this endocytic process. Taken together, these data demonstrate that at steady state, CD36 is localized in lipid rafts but not in caveolae, and that binding of OxLDL to CD36 leads to endocytosis through a lipid raft pathway that is distinct from the clathrin-mediated or caveolin internalization pathways.
Post-traumatic Growth in the Italian Experience of Long-term Disease-free Cancer Survivors.

Cancer survivors often report post-traumatic growth. Since culture influences the development of post-traumatic growth, the aims of this study were to measure the prevalence of post-traumatic growth in Italian long-term disease-free and treatment-free cancer survivors (≥5 years) and explore the relationship between post-traumatic growth and sociodemographic and clinical variables. Three hundred sixty long-term disease-free and treatment-free cancer survivors were assessed with Post-traumatic Growth Inventory (PTGI), Brief COPE and Multidimensional Scale of Perceived Social Support (MSPSS). Mean age was 58.6 years, and mean survival was 11 years (range 5-32). The PTGI average total score was higher in younger survivors, in those without comorbidities, in survivors engaged in physical activity. Positive correlation between PTGI and Brief COPE and between PTGI and MSPSS were found. The variables more associated with post-traumatic growth were age, comorbidity, physical activity and two coping subscales. The prevalence of post-traumatic growth in this sample of cancer survivors was lower than previous studies. We discussed some possible explanations, including the consideration that cultural differences may affect the development of post-traumatic growth in cancer survivors. Having less comorbidities, receiving social support from friends, having the ability to adaptively cope and engaging in physical activity were found to be strongly associated with post-traumatic growth.
Vitamin D3 down‐regulates monocyte TLR expression and triggers hyporesponsiveness to pathogen‐associated molecular patterns

Toll‐like receptors (TLR) represent an ancient front‐line defence system that enables the host organism to sense the presence of microbial components within minutes. As inducers of inflammation, TLR act as important triggers of distinct entities such as sepsis or autoimmune disease exacerbation. We report here that vitamin D3 [1α,25‐dihydroxycholecalciferol, 1,25(OH)2D3] suppresses the expression of TLR2 and TLR4 protein and mRNA in human monocytes in a time‐ and dose‐dependent fashion. Despite 1,25(OH)2D3‐induced up‐regulation of CD14, challenge of human monocytes with either LPS or lipoteichoic acid resulted in impaired TNF‐α and procoagulatory tissue factor (CD142) production, emphasizing the critical role of TLR in the induction of inflammation. Moreover, reduced TLR levels in 1,25(OH)2D3‐treated phagocytes were accompanied by impaired NF‐κB/RelA translocation to the nucleus and by reduced p38 and p42/44 (extracellular signal‐regulated kinase 1/2) phosphorylation upon TLR‐ligand engagement. Both TLR down‐regulation and CD14 up‐regulation were substantially inhibited by the vitamin D receptor (VDR) antagonist ZK 159222, indicating that the immunomodulatory effect of 1,25(OH)2D3 on innate immunity receptors requires VDR transcription factor activation. Our data provide strong evidence that 1,25(OH)2D3 primes monocytes to respond less effectively to bacterial cell wall components in a VDR‐dependent mechanism, most likely due to decreased levels of TLR2 and TLR4.
Mindfulness-Based Parent Training: Strategies to Lessen the Grip of Automaticity in Families With Disruptive Children

Disagreements and conflicts in families with disruptive children often reflect rigid patterns of behavior that have become overlearned and automatized with repeated practice. These patterns are mindless: They are performed with little or no awareness and are highly resistant to change. This article introduces a new, mindfulness-based model of parent training and contrasts the model's assumptions with those of behavioral (operant) parent training. The new model informs 3 strategies to lessen the grip of automaticity in families with disruptive children: facilitative listening, distancing, and motivated action plans. The article does not oppose mindfulness to mindlessness or suggest that the former is always better than the latter but instead proposes that each is most useful at different times in the parenting process. I conclude by calling for empirical investigations of mindfulness-based parent training and, if those are successful, for the development of an integrated model that blends behavioral and mindfulness-based principles to inform all facets of intervention.
