Embryo selection criteria based on morphology VERSUS the expression of a biochemical marker (sHLA-G) and a graduated embryo score: prediction of pregnancy outcome

Purpose  

To compare pregnancy and implantation rates when embryos are selected based on a single Day 3 (D 3) morphology score vs. a GES score plus sHLA-G expression.     

Elevated TSH levels in a mentally retarded boy

The Allan–Herndon–Dudley syndrome (AHDS; MIM 300523) of X-linked mental retardation and hypotonia is caused by mutations in a thyroid hormone transporter gene—the monocarboxylate transporter 8 (MCT8 also known as SLC16A2) gene. A 23-month-old boy with severe developmental delay, hypotonia, recurrent emesis, and irritability is described. He was diagnosed with hypothyroidism at the age of 4 months. However, T3 level was elevated. Molecular analysis of the MCT8 gene detected a single base duplication in exon 5 c.1614dupC (p.Ile539fs), consistent with a diagnosis of AHDS. While T3 is the best marker for this disorder, elevations in TSH should alert to the diagnosis.     

What I wish I��d known before surgery: BRCA carriers�� perspectives after bilateral salipingo-oophorectomy

We retrospectively studied BRCA carriers with a history of prophylactic bilateral salingo-oophorectomy (PBSO) regarding: (1) their post-operative symptoms, (2) their recollection of pre-operative conversations with their health care providers regarding possible surgical side-effects and (3) what information they would have found helpful to have before surgery. Female BRCA carriers seen through the Yale Cancer Genetic Counseling Program who had PBSO were invited to participate in a questionnaire that assessed their recall of information they received pre-operatively compared with their post-operative knowledge and symptoms related to menopause, cognitive changes, loss of fertility, cancer risks, osteoporosis, heart disease, vasomotor symptoms, urogenital symptoms, sexuality and body image. The questionnaire also elicited written feedback from participants regarding their decision to have PBSO, what they wished they had known before surgery, advice for other BRCA carriers considering this surgery and advice for health care providers who counsel women about PBSO. Two hundred and ninety female BRCA carriers were invited to participate and 113 (39.0%) indicated they were interested. Of those, 99 (87.6%) returned their questionnaire and 98 (86.7%) responses were included in the analysis. The mean age at PBSO was 45.5 years (range: 32–63 years). The five most common “frequent” or “very frequent” post-surgical symptoms were: vaginal dryness (52.1%), changes in interest in sex (50.0%), sleep disturbances (46.7%), changes in sex life (43.9) and hot flashes (42.9%). The majority of women would have found it helpful to have more information regarding the impact of this surgery on their sex life (59.2%), the availability of sex counseling (57.1%) and the risk of coronary heart disease (57.1%). This study illustrates that while health care providers are discussing selected side effects of PBSO, women undergoing this surgery have other concerns that should be addressed. This information provides insights into the informational needs of BRCA carriers considering PBSO.     

Spatial and seasonal patterns in climate change,temperatures, and precipitation across the United States

Changes in climate during the 20th century differ from region to region across the United States. We provide strong evidence that spatial variations in US temperature trends are linked to the hydrologic cycle, and we also present unique information on the seasonal and latitudinal structure of the linkage. We show that there is a statistically significant inverse relationship between trends in daily temperature and average daily precipitation across regions. This linkage is most pronounced in the southern United States (30–40°N) during the May-June time period and, to a lesser extent, in the northern United States (40–50°N) during the July-August time period. It is strongest in trends in maximum temperatures (T_max) and 90th percentile exceedance trends (90PET), and less pronounced in the T_max 10PET and the corresponding T_min statistics, and it is robust to changes in analysis period. Although previous studies suggest that areas of increased precipitation may have reduced trends in temperature compared with drier regions, a change in sign from positive to negative trends suggests some additional cause. We show that trends in precipitation may account for some, but not likely all, of the cause point to evidence that shows that dynamical patterns (El Niño/Southern Oscillation, North Atlantic Oscillation, etc.) cannot account for the observed effects during May-June. We speculate that changing aerosols, perhaps related to vegetation changes, and increased strength of the aerosol direct and indirect effect may play a role in the observed linkages between these indices of temperature change and the hydrologic cycle.     

Sexism and Professional Chauvinism in Psychiatry

Objective: The present study tested the maturation and inoculation hypotheses by examining whether age and previous exposure to the September 11, 2001, World Trade Center (WTC) terrorist attack moderated the relationship between degree of exposure to Hurricane Sandy and related posttraumatic stress disorder (PTSD) symptoms. Method: An online sample of 1,000 participants from affected states completed self-report questionnaires one month after Hurricane Sandy hit the East Coast. Participants reported their degree of exposure to the WTC terrorist attack and to Hurricane Sandy, and their posttraumatic stress disorder (PTSD) symptoms following Hurricane Sandy. Results: The positive relationship between degree of exposure to Hurricane Sandy and level of PTSD symptoms was weaker among older adults. An additional significant three-way interaction suggested that both age and previous exposure to the WTC terrorist attack moderated the relationship between degree of exposure to Hurricane Sandy and level of PTSD symptoms. Previous high degree of exposure to the WTC terrorist attack was related to a weaker effect of current exposure to Hurricane Sandy on PTSD symptoms among older adults. However, among younger adults, previous high degree of exposure to the WTC terrorist attack was related to a stronger effect of current exposure on PTSD symptoms. Conclusions: When confronted by a natural disaster, American older adults are generally resilient. Supporting the inoculation hypothesis, resilience of older adults may be partly related to the strength successfully extracted from previous exposure to adverse events.     

Zoonotic potential of multidrug-resistant extraintestinal pathogenic Escherichia coli obtained from healthy poultry carcasses in Salvador,Brazil

The zoonotic potential to cause human and/or animal infections among multidrug-resistant extraintestinal pathogenic Escherichia coli from avian origin was investigated. Twenty-seven extraintestinal pathogenic E. coli isolates containing the increased survival gene (iss) were obtained from the livers of healthy and diseased poultry carcasses at two slaughterhouses in Salvador, northeastern Brazil. The antimicrobial resistance-susceptibility profiles were conducted with antibiotics of avian and/or human use by the standardized disc-diffusion method. Antimicrobial resistance was higher for levofloxacin (51.8%), amoxicillin/clavulanic acid (70.4%), ampicillin (81.5%), cefalotin (88.8%), tetracycline (100%) and streptomycin (100%). The minimum inhibitory concentrations above the resistance breakpoints of doxycycline, neomycin, oxytetracycline and enrofloxacin reached, respectively, 88.0%, 100%, 75% and 91.7% of the isolates. Strains with high and low antimicrobial resistance were i.p. administered to Swiss mice, and histopathological examination was carried out seven days after infection. Resistance to goat and human serum complement was also evaluated. The results show that Swiss mice challenged with strain 2B (resistant to 11 antimicrobials) provoked a severe degeneration of hepatocytes besides lymphocytic infiltration in the liver, whereas the spleen showed areas of degeneration of the white and red pulp. Conversely, the spleen and liver of mice challenged with strain 4A (resistant to two antimicrobials) were morphologically preserved. In addition, complement resistance to goat and human serum was high for strain 2B and low for strain 4A. Our data show that multidrug resistance and pathogenesis can be correlated in extraintestinal pathogenic E. coli strains obtained from apparently healthy poultry carcasses, increasing the risk for human public healthy.
