BACKGROUND: While breast cancer has historically been treated with surgery followed by adjuvant chemotherapy (AC) and radiation when indicated, neoadjuvant chemotherapy (NAC) use is thought to be increasing; however, the trends of its use in various biological subtypes have not been evaluated. We sought to evaluate the trend of NAC use over time by biological subtype. METHODS: We identified all patients with invasive breast cancer who underwent curative intent surgery and were treated with chemotherapy from 2010 to 2015 from the National Cancer Database...

PURPOSE: To examine the management and associated outcomes of reported cases of interface fungal infection after Descemet stripping automated endothelial keratoplasty (EK). METHODS: A literature review identified reports of interface fungal infection after Descemet stripping automated EK. Data retrieved from the same included patient demographics, surgical procedure undertaken, donor rim culture result, clinical course, and outcome. A review of the relevant literature was also conducted...

Outbreaks associated with exposure to treated recreational water can be caused by pathogens or chemicals in venues such as pools, hot tubs/spas, and interactive water play venues (i.e., water playgrounds). During 2000-2014, public health officials from 46 states and Puerto Rico reported 493 outbreaks associated with treated recreational water. These outbreaks resulted in at least 27,219 cases and eight deaths. Among the 363 outbreaks with a confirmed infectious etiology, 212 (58%) were caused by Cryptosporidium (which causes predominantly gastrointestinal illness), 57 (16%) by Legionella (which causes Legionnaires' disease, a severe pneumonia, and Pontiac fever, a milder illness with flu-like symptoms), and 47 (13%) by Pseudomonas (which causes folliculitis ["hot tub rash"] and otitis externa ["swimmers' ear"])...

Background: Metaplastic breast cancer (MBC), characterized by admixed epithelial, squamous or mesenchymal elements, constitutes <1% of breast cancers and has a poor prognosis but a paradoxically low reported rate of axillary lymph node (LN) involvement. Due to its rarity, data on appropriate axillary management is lacking, prompting this investigation of LN status and outcomes. Methods: We identified 41 MBC patients treated at our institution 2001-2011 who were followed for a median of 66 months...

BACKGROUND: Despite surgical correction procedures for pectus deformities, remaining cosmetic asymmetry may have significant psychological effects. We sought to evaluate factors associated with plastic surgery (PS) consultation and procedures for these deformities at an academic institution. METHODS: We reviewed patients aged 0-21 diagnosed with a pectus excavatum or carinatum deformity at our institution between January 2001 and October 2016. Pectus diagnoses were identified by ICD-9/ICD-10 codes and surgical repair by CPT codes; patients receiving PS consultation were identified by clinical note service codes...

CASE: We present 3 pediatric cases of osteomyelitis with delayed diagnosis, which resulted in systemic inflammatory response syndrome (SIRS) and complicated hospital stays. CONCLUSION: These 3 cases illustrate that early treatment of osteomyelitis is imperative in order to avoid fatal complications, which can occur with SIRS. Subtle signs and symptoms should not be dismissed. Patients with fever, pain, and no history of trauma should be scrutinized.

For patients with ductal carcinoma In Situ (DCIS), sentinel lymph node (SLN) surgery is generally reserved for patients at high risk of being upstaged to invasive disease. The use of frozen section (FS) pathologic analysis of the primary tumor may allow for selective surgical nodal staging within one procedure. We sought to define the reliability of FS for detection of upstaging. Eight hundred and twenty-seven patients were identified with DCIS on core needle biopsy that underwent 834 operations at our institution between January 2004 and October 2014...

A cascade of alternative sigma factors directs developmental gene expression during spore formation by the bacterium Bacillus subtilis. As the spore develops, a tightly regulated switch occurs in which the early-acting sigma factor σF is replaced by the late-acting sigma factor σG. The gene encoding σG (sigG) is transcribed by σF and by σG itself in an autoregulatory loop; yet σG activity is not detected until σF-dependent gene expression is complete. This separation in σF and σG activities has been suggested to be due at least in part to a poorly understood intercellular checkpoint pathway that delays sigG expression by σF...

BACKGROUND: Little evidence is available for head-to-head comparisons of psychosocial interventions and pharmacological interventions in psychosis. We aimed to establish whether a randomised controlled trial of cognitive behavioural therapy (CBT) versus antipsychotic drugs versus a combination of both would be feasible in people with psychosis. METHODS: We did a single-site, single-blind pilot randomised controlled trial in people with psychosis who used services in National Health Service trusts across Greater Manchester, UK...

The invention of liver-humanized mouse models has made it possible to directly study the preerythrocytic stages of Plasmodium falciparum . In contrast, the current models to directly study blood stage infection in vivo are extremely limited. Humanization of the mouse blood stream is achievable by frequent injections of human red blood cells (hRBCs) and is currently the only system with which to study human malaria blood stage infections in a small animal model. Infections have been primarily achieved by direct injection of P...

Preclinical studies demonstrate that environmentally-induced alterations in inflammatory cytokines generated by the maternal and fetal immune system can significantly impact fetal brain development. Yet, the relationship between maternal cytokines during gestation and later cognitive ability and executive function remains understudied. Children (n = 246) were born of mothers enrolled in the Newborn Epigenetic Study - a prospective pre-birth cohort in the Southeastern US. We characterized seven cytokines [IL-1β, IL-4,IL-6, IL-12p70, IL-17A, tumor necrosis factor-α (TNFα), and interferon-γ (IFNγ)] and one chemokine (IL-8) from maternal plasma collected during pregnancy...

Induced pluripotent stem cells (iPSCs) stand to revolutionize the way we study human development, model disease, and eventually, treat patients. However, these cell sources produce progeny that retain embryonic and/or fetal characteristics. The failure to mature to definitive, adult-type cells is a major barrier for iPSC-based disease modeling and drug discovery. To directly address these concerns, we have developed a chemically defined, serum and feeder-free-directed differentiation platform to generate hematopoietic stem-progenitor cells (HSPCs) and resultant adult-type progeny from iPSCs...

Here we describe new fluorescent probes based on fluorescein and rhodamine that provide reversible, real-time insight into cellular redox status. The new probes incorporate bio-imaging relevant fluorophores derived from fluorescein and rhodamine linked with stable nitroxide radicals such that they cannot be cleaved, either spontaneously or enzymatically by cellular processes. Overall fluorescence emission is determined by reversible reduction and oxidation, hence the steady state emission intensity reflects the balance between redox potentials of critical redox couples within the cell...

Fructose feeding increases hepatic de novo lipogenesis (DNL) and is associated with non-alcoholic fatty liver disease. Little is known, however, about individual variation in susceptibility to fructose stimulation of DNL. In this three-period, cross-over study, seventeen healthy male subjects were enrolled to evaluate the within and between subject variability of acute fructose feeding on hepatic fractional DNL. During each assessment, [1-13 C1 ]-acetate was infused to measure DNL in the fasting state and during fructose feeding...

Force-dependent binding of platelet glycoprotein Ib (GPIb) receptors to plasma von Willebrand factor (VWF) plays a key role in hemostasis and thrombosis. Previous studies have suggested that VWF activation requires force-induced exposure of the GPIb binding site in the A1 domain that is autoinhibited by the neighboring A2 domain. However, the biochemical basis of this "mechanopresentation" remains elusive. From a combination of protein chemical, biophysical, and functional studies, we find that the autoinhibition is controlled by the redox state of an unusual disulfide bond near the carboxyl terminus of the A2 domain that links adjacent cysteine residues to form an eight-membered ring...

Energy metabolism is a key aspect of cardiomyocyte biology. Human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) are a promising tool for biomedical application, but they are immature and have not undergone metabolic maturation related to early postnatal development. To assess whether cultivation of hiPSC-CMs in 3D engineered heart tissue format leads to maturation of energy metabolism, we analyzed the mitochondrial and metabolic state of 3D hiPSC-CMs and compared it with 2D culture. 3D hiPSC-CMs showed increased mitochondrial mass, DNA content, and protein abundance (proteome)...

OBJECTIVES: Little is known about the relationship between having a first-degree relative (FDR) with colorectal cancer (CRC) and risk for metachronous colorectal adenoma (CRA) following polypectomy. METHODS: We pooled data from seven prospective studies of 7697 patients with previously resected CRAs to quantify the relationship between having a FDR with CRC and risk for metachronous adenoma. RESULTS: Compared with having no family history of CRC, a positive family history in any FDR was significantly associated with increased odds of developing any metachronous CRA (OR = 1...
