Placental Transfusion for Asphyxiated Infants.
The current recommendation for umbilical cord management of non-vigorous infants (limp, pale, and not breathing) who need resuscitation at birth is to immediately clamp the umbilical cord. This recommendation is due in part to insufficient evidence for delayed cord clamping (DCC) or umbilical cord milking (UCM). These methods may provide a neuroprotective mechanism that also facilitates cardiovascular transition for non-vigorous infants at birth
Induction chemotherapy in the treatment of nasopharyngeal carcinoma: Clinical outcomes and patterns of care
Nab-paclitaxel-based compared to docetaxel-based induction chemotherapy regimens for locally advanced squamous cell carcinoma of the head and neck
We previously reported that nab-paclitaxel-based induction chemotherapy (IC) and concurrent chemoradiotherapy resulted in low relapse rates (13%) and excellent survival in head and neck squamous cell carcinoma (HNSCC). We compare the disease-specific survival (DSS) and overall survival (OS) between patients given nab-paclitaxel, cisplatin, and fluorouracil with cetuximab (APF-C) and historical controls given docetaxel, cisplatin, and fluorouracil with cetuximab (TPF-C). Patients with locally advanced HNSCC were treated with APF-C (n = 30) or TPF-C (n = 38). After 3 cycles of IC, patients were scheduled to receive cisplatin concurrent with definitive radiotherapy. T and N classification and smoking history were similar between the two groups and within p16-positive and p16-negative subsets. The median duration of follow-up for living patients in the APF-C group was 43.5 (range: 30–58) months versus 52 (range: 13–84) months for TPF-C. The 2-year DSS for patients treated with APF-C was 96.7% [95% Confidence Interval (CI): 85.2%, 99.8%] and with TPF-C was 77.6% (CI: 62.6%, 89.7%) (P = 0.0004). Disease progression that resulted in death was more frequent in the TPF-C group (39%) compared with the APF-C group (3%) when adjusted for competing risks of death from other causes (Gray's test, P = 0.0004). In p16 positive OPSCC, the 2-year DSS for APF-C was 100% and for TPF-C was 74.6% (CI: 47.4%, 94.6%) (P = 0.0019) and the 2-year OS for APF-C was 94.1% (CI: 65.0%, 99.2%) and for TPF-C was 74.6% (CI: 39.8%, 91.1%) (P = 0.013). In p16 negative HNSCC, the 2-year DSS for APF-C was 91.7% (CI: 67.6%, 99.6%) and for TPF-C was 82.6% (CI: 64.4%, 94.8%) (P = 0.092). A 2-year DSS and OS were significantly better with a nab-paclitaxel-based IC regimen (APF-C) compared to a docetaxel-based IC regimen (TPF-C) in p16-positive OPSCC

Increased Mortality Associated with Well-Water Arsenic Exposure in Inner Mongolia, China
We conducted a retrospective mortality study in an Inner Mongolian village exposed to well water contaminated by arsenic since the 1980s. Deaths occurring between January 1, 1997 and December 1, 2004 were classified according to underlying cause and water samples from household wells were tested for total arsenic. Heart disease mortality was associated with arsenic exposure, and the association strengthened with time exposed to the water source. Cancer mortality and all-cause mortality were associated with well-water arsenic exposure among those exposed 10–20 years. This is the first study to document increased arsenic-associated mortality in the Bayingnormen region of Inner Mongolia
Well Water Arsenic Exposure, Arsenic Induced Skin-Lesions and Self-Reported Morbidity in Inner Mongolia
Residents of the Bayingnormen region of Inner Mongolia have been exposed to arsenic-contaminated well water for over 20 years, but relatively few studies have investigated health effects in this region. We surveyed one village to document exposure to arsenic and assess the prevalence of arsenic-associated skin lesions and self-reported morbidity. Five-percent (632) of the 12,334 residents surveyed had skin lesions characteristics of arsenic exposure. Skin lesions were strongly associated with well water arsenic and there was an elevated prevalence among residents with water arsenic exposures as low as 5 μg/L-10 μg/L. The presence of skin lesions was also associated with self-reported cardiovascular disease
Luminous Blue Variable eruptions and related transients: Diversity of progenitors and outburst properties
We present new light curves and spectra for a number of extragalactic optical
transients or "SN impostors" related to giant eruptions of LBVs, and we provide
a comparative discussion of LBV-like giant eruptions known to date. New data
include photometry and spectroscopy of SNe1999bw, 2000ch, 2001ac, 2002bu,
2006bv, and 2010dn. SN2010dn resembles SN2008S and NGC 300-OT, whereas SN2002bu
shows spectral evolution from a normal LBV at early times to a twin of these
cooler transients at late times. SN2008S, NGC300-OT, and SN2010dn appear to be
special cases of a broader eruptive phenomenon where the progenitor star was
enshrouded by dust. Examining the full sample, SN impostors have range of
timescales from a day to decades, potentially suffering multiple eruptions. The
upper end of the luminosity distribution overlaps with the least luminous SNe.
The low end of the luminosity distribution is poorly defined, and a distinction
between various eruptions is not entirely clear. We discuss observational clues
concerning winds or shocks as the relevant mass-loss mechanism, and we evaluate
possible ideas for physical mechanisms. Although examples of these eruptions
are sufficient to illustrate their diversity, their statistical distribution
will benefit greatly from upcoming transient surveys. Based on the distribution
of eruptions, we propose that SN1961V was not a member of this class of
impostors, but was instead a true core-collapse SNIIn preceded by a giant LBV
eruption. (abridged)Comment: 36(!) journal pages, 16 figures. submitted to MNRAS on october 12.
