RESUMEN
Most of the animal studies using inflammation-induced cognitive change have relied on behavioral testing without objective and biologically solid methods to quantify the severity of cognitive disturbances. We have developed a bispectral EEG (BSEEG) method using a novel algorithm in clinical study. This method effectively differentiates between patients with and without delirium, and predict long-term mortality. In the present study, we aimed to apply our bispectral EEG (BSEEG) method, which can detect patients with delirium, to a mouse model of delirium with systemic inflammation induced by lipopolysaccharides (LPS) injection. We recorded EEG after LPS injection using wildtype early adulthood mice (2~3-month-old) and aged mice (18-19-month-old). Animal EEG recordings were converted for power spectral density to calculate BSEEG score using the similar BSEEG algorithm previously developed for our human study. The BSEEG score was relatively stable and slightly high during the day. Alternatively, the BSEEG score was erratic and low in average during the night. LPS injection increased the BSEEG score dose-dependently and diminished the diurnal changes. The mean BSEEG score increased much more in the aged mice group as dosage increased. Our results suggest that BSEEG method can objectively "quantify" level of neuro-Inflammation induced by systemic inflammation (LPS), and that this BSEEG method can be useful as a model of delirium in mice.

PURPOSE: The objective of this study was to investigate stress levels among women undergoing elective oocyte cryopreservation by comparing their self-reported quality of life measures with women undergoing in vitro fertilization during the fertility treatment cycle. METHODS: Patients undergoing oocyte retrieval at a single institution were offered a voluntary, anonymous, and written questionnaire. The survey was adapted and validated from the Fertility Quality of Life tool to assess self-reported fertility treatment-related problems and was tested for construct validity and reliability. Based on exploratory factor analyses, three subscales were created as follows: fertility treatment-related stress, tolerability, and environment. Relationships between patient characteristics and fertility treatment-related measures were examined with Fisher's exact test, ANOVA, and multivariate regression with significance p < 0.05. RESULTS: A total of 461 patients (331 IVF, 130 egg freeze) were included in the analysis. Medically indicated egg freezing patients were excluded. Overall, both IVF and egg freeze patients reported stress during the current fertility cycle and there were no significant differences between IVF and egg freeze patients for any subscale scores. Three sets of generalized linear models were run and found age to be associated with fertility treatment-related stress and tolerability scores, with younger patients experiencing greater difficulties. Additionally, patients who underwent repeat cycles reported more fertility treatment-related stress. CONCLUSIONS: Patients undergoing egg freezing have similar responses to quality of life questions as patients undergoing IVF. Repeat cycles and younger age contribute to perceptions of stress. This information supports developing stress reduction strategies for all women undergoing egg freezing.

PURPOSE: To assess the experiences and psychological outcomes of oocyte donors from one fertility center. METHODS: An anonymous survey was distributed via a secure email to 161 donors who underwent oocyte donation-anonymous, directed/known, and recruited agency-between January 2008 and January 2019 at the NYU Langone Fertility Center. RESULTS: Thirty-six donors completed the survey with the majority between 2 and 10 years since donation. Respondents reported a high prevalence of psychiatric symptoms or diagnoses post-donation. The majority of donors reported positive thoughts and feelings toward their donation process as well as to the knowledge of children born from their donation. Negative comments about donation were in the minority but focused on unexpected aspects about the process or outcome. Based on qualitative analysis, thoughts about family or "family-oriented thoughts" were the most frequent theme in respondent comments. 62.5% of respondents reporting that they would be open to identity-disclosure or open donation after experiencing the process. CONCLUSIONS: Despite a high reported prevalence of psychiatric symptoms, the majority of respondents felt positively about the donation experience as well as the prospect of open donation or identity-disclosure post-donation. Further research on long-term psychological outcomes, related to all aspects of donation, is important as the counseling and informed consent of oocyte donors continues to evolve. These data will be particularly important with regard to the aspect of disclosure, both planned and unplanned, in the modern era of electronic information sharing.

OBJECTIVES: The ability of the Bellamy et al. Low-Intensity Symptom State-attainment (BLISS) Index to differentiate between treatment groups (hylan G-F 20 vs. appropriate care) at low and very low levels of state attainment in patients with knee osteoarthritis was explored using the stiffness, function, and total index (TI) components of the WOMAC. STUDY DESIGN AND SETTING: Six different BLISS measures were analyzed using five WOMAC score thresholds: Asunto(s)

RESUMEN
Iodobenzene diacetate in MeOH containing a catalytic amount of TFA efficiently oxidizes aldoximes to nitrile oxides. The latter may be trapped in situ with olefins in a bimolecular or an intramolecular mode. The new method enables the execution of tandem oxidative dearomatization of phenols/intramolecular nitrile oxide cycloaddition sequences leading to useful synthetic intermediates.

The Structured Clinical Interview for DSM-III-R (SCID-I) and the Adult Attachment Interview (AAI) were administered to 60 women participating in a study (n=226) of mother-child interaction. These women were not referred to the study for psychiatric care. The 60 women interviewed with the AAI were selected from the first 190 women who completed the SCID-I, so that 30 received a diagnosis and 30 did not. Analyses indicated that psychopathology diagnoses were associated significantly with mental representations of attachment classified in the AAI. The non-autonomous groups had increased likelihood of SCID diagnosis, compared to the autonomous group. While 32% of women with autonomous AAI transcripts received SCID diagnoses, 63% of women with Dismissing, 100% of woman with Preoccupied, and 65% of women with Unresolved transcripts received diagnoses. Secondary analyses indicated that Dismissing classifications were associated with Axis I diagnoses and Preoccupied classifications with affective disorders. Of note was that among women with Unresolved classifications, underlying secure attachment was associated with low risk of psychopathology, while underlying anxious attachment was associated with elevated risk of diagnosis. These findings support the premise from attachment theory that early relationships affect patterns of interpersonal expectations and behavior and affect regulation.
