Gravitational lens candidates in the E-CDFS
We report ten lens candidates in the E-CDFS from the GEMS survey. Nine of the
systems are new detections and only one of the candidates is a known lens
system. For the most promising five systems including the known lens system, we
present results from preliminary lens mass modelling, which tests if the
candidates are plausible lens systems. Photometric redshifts of the candidate
lens galaxies are obtained from the COMBO-17 galaxy catalog. Stellar masses of
the candidate lens galaxies within the Einstein radius are obtained by using
the -band luminosity and the color-based stellar mass-to-light ratios.
As expected, the lensing masses are found to be larger than the stellar masses
of the candidate lens galaxies. These candidates have similar dark matter
fractions as compared to lenses in SLACS and COSMOS. They also roughly follow
the halo mass-stellar mass relation predicted by the subhalo abundance matching
technique. One of the candidate lens galaxies qualifies as a LIRG and may not
be a true lens because the arc-like feature in the system is likely to be an
active region of star formation in the candidate lens galaxy. Amongst the five
best candidates, one is a confirmed lens system, one is a likely lens system,
two are less likely to be lenses and the status of one of the candidates is
ambiguous. Spectroscopic follow-up of these systems is still required to
confirm lensing and/or for more accurate determination of the lens masses and
mass density profiles.Comment: 12 pages, 5 figures, 3 tables, ApJ accepte
Changing the Face of Medicine: One Historian\u27s Experience as a Curator
In the spring of 2001 during a meeting of the American Association for the History of Medicine, Elizabeth Fee, Chief of the History of Medicine Division of the National Library of Medicine (NLM), invited me to become the Visiting Curator for a new exhibition they intended to present on the history of women physicians. It was the first full-scale exhibition ever devoted to that subject by the NLM. After more than two yearsâ preparation, the exhibition, âChanging the Face of Medicine: Celebrating Americaâs Women Physicians,â opened in April 2003 and continued on display at the NLM for more than two years. Recently I had published a history of women in American medicine, Restoring the Balance: Women Physicians and the Profession of Medicine, 1850-1995. After years of archival research and secondary source reading, I had arrived at a narrative structure and a set of unifying thematic ideas centered around the various ways women physicians relied on the concept of balance as a touchstone for their sense of purpose and identity. Although I possessed no curatorial experience whatever, I (mistakenly) thought I could foresee the narrative strategy our exhibition would employ. Archival Elements has asked me to write about my experiences
Fever in pregnancy and its maternal and fetal outcomes
Background: Contemporary obstetrics has witnessed improved maternal and fetal outcomes, owing to several advances. Any source of maternal hyperthermia that results in significant core temperature increase (>38.9°C), could potentially affect the fetus.  Hence a study was planned to know the effect of fever on maternal and fetal outcome.Methods: This was a retrospective cohort analysis of case-records, of patients admitted in the Department of Obstetrics and Gynecology at tertiary care centre, Mumbai, between May 2007 and October 2009. The main parameters of assessment included incidence of fever in pregnancy, causes of fever, effect of episode(s) of fever on maternal and fetal outcomes, effect of specific infection on maternal and fetal outcomes, impact of fever on antepartum, intrapartum and postpartum phasesResults: The incidence of fever was 10.5%. the common cause of fever was malaria (15%), urinary tract infection (14%), viral (14%), respiratory tract infection (18%), and typhoid (7%). Seventy eight percent had fever in third trimester. The most common antenatal complication observed was preterm (13%), premature rupture of membrane (12%), oligohydramnios (8%), intrauterine growth retardation (26%). The rate of LSCS was 13% in study group and the most common indication was fetal distress and meconium stained amniotic fluid.Conclusions: In the present study on fever during pregnancy and its maternal and fetal outcomes, fever was associated with a definite impact on maternal and fetal outcomes. Preterm and IUGR were the most common fetal complications. Duration of fever was linearly associated with poor outcomes. Different causes of fever also had different impact on maternal and fetal outcome. Preterm IUGR, MSAF were more common with malaria and tuberculosis. Abortion was more commonly seen in first trimester fever, whereas preterm, PROM in the third trimester fever. Hence it is suggested that fever during pregnancy needs to be promptly investigated and treated to have a better outcome
The University of Massachusetts Medical School, A History: Integrating Primary Care and Biomedical Research
When an all-male class of 16 students entered the new University of Massachusetts Medical School in 1970, they might well have wondered whether they were making a huge mistake. Undoubtedly they took an enormous risk. The entire schoolâfaculty, students, staff, laboratories, offices and classroomsâwas housed in a small converted warehouse. The faculty probably had their doubts as well. Not so Dr. Lamar Soutter, the schoolâs founding dean and guiding spirit. No matter how many times the state legislature threatened to withhold the schoolâs funding, or how many governors threatened to shut it down altogether, Soutter knew he could outlast them all.
The University of Massachusetts Medical School, chartered in 1962 and opened in 1970, was one of a cohort of medical schools founded in response to fears of a physician shortage. In Massachusetts, this translated into a call for more opportunities for the stateâs students to attend an affordable school where, it was hoped, they would deliver primary care to the people of their home state. Yet, Dean Soutter and the original faculty, most of whom were basic scientists recruited from Boston medical schools, were equally devoted to basic research and tertiary care medicine. This book tells the story of the schoolâs struggle, and eventual success in reconciling the demands of primary care education with world-class research.
A revised version of this online history titled Beating the Odds: The University of Massachusetts Medical School, a History, 1962-2012 (TidePool Press, 2017), is available in hard cover from the publisher, from Amazon, or at the UMMS book store.
Author biography
Ellen S. More, Ph.D., a historian of medicine, is Professor Emeritus of psychiatry at the University of Massachusetts Medical School.

Empathy as a Hermeneutic Practice
This essay will argue for the centrality of empathy in the doctor-patient relationship-as a core of ethically sound, responsible therapeutics. By empathy, I intend an explicitly hermeneutic practice, informed by a reflexive understanding of patient and self. After providing an overview of the history of the concept of empathy in clinical medicine, I discuss current definitions and the use of Balint groups in residency training as a way to develop empathic competence in novice physicians
