Introduction Maternal exposure to tobacco smoke is associated with shortened breastfeeding duration, but few studies have examined the effects on breastfeeding outcomes of low level exposures to other toxic chemicals. Moreover, it is unclear if passive smoking is associated with duration of breastfeeding. Our objective was therefore to examine the effect of low-level prenatal exposures to common environmental toxins (tobacco smoke, lead, and phthalates) on breastfeeding exclusivity and duration. Methods We conducted an analysis of data from the Health Outcomes and Measures of the Environment (HOME) Study...

OBJECTIVES: Chronic accumulation of lactate in malignant tumor tissue is associated with increased malignancy and radioresistance. For this study, biopsies of primary head and neck squamous cell carcinoma (HNSCC) and of the normal gingiva of the same patient were compared via metabolic profiling to the healthy gingiva from cancer-free patients. MATERIALS AND METHODS: Cryobiopsies of 140 HNSCC patients were used to determine ATP, lactate, and glucose concentrations of the tumor and normal gingiva via induced metabolic bioluminescence imaging (imBI)...

Group A rotavirus (RVA) acute gastroenteritis (AGE) is a common cause of severe childhood diarrhea. The dominant circulating RVA genotypes in a given region may vary between and within the geographic regions and from year to year. Our cross-sectional study was designed to determine the burden of RVA genotypes among children with AGE admitted to referral Children Hospital at Egypt prior to implementation of the vaccine. Stool samples with clinico-epidemiological data were collected from 92 children ≤ 3 years-old with AGE...

The traditional CaCO3-based fermentation process generates huge amount of insoluble CaSO4 waste. To solve this problem, we have developed an efficient and green D-lactic acid fermentation process by using ammonia as neutralizer. The 106.7 g/L of D-lactic acid production and 0.89 g per g of consumed sugar were obtained by Sporolactobacillus inulinus CASD with a high optical purity of 99.7% by adding 100 mg/L betaine in the simple batch fermentation process. The addition of betaine was experimentally proven to protect cell at high concentration of ammonium ion, increase the D-lactate dehydrogenase specific activity and thus promote the production of D-lactic acid...

This study assessed infant sleep-wake behavior at two weeks, three and six months as function of feeding method at three months (exclusively breastfed, partially breastfed, and exclusively formula fed infants). Mothers of 163 first-born, full-term, normal birth weight, healthy infants completed socio-demographic, depression, anxiety, and infant sleep-wake behavior measures. No effects were found for sleep arrangements, depression or anxiety, on feeding methods and sleep-wake behavior at three months. At two weeks exclusively breastfed infants at three months spent more hours sleeping and less hours awake during the 24-h period than partially breastfed infants...

Irinotecan (CPT-11) is an effective chemotherapeutic agent widely used to treat different cancers. Otherwise, the liposomal delivery of anti-tumor agents has been shown to be a promising strategy. The aim of this study has been to analyze the effect of liposomal CPT-11 (CPT-11lip) on two human cell lines (Hs68 and HeLa) to establish the suitability of this CPT-11 nanocarrier. We have demonstrated the highest uptake of CPT-11lip in comparison with that of CPT-11sol, in lactate buffer, and that CPT-11lip was internalized in the cells through an endocytic process whereas CPT-11sol does so by passive diffusion...

OBJECTIVE: Women with a higher BMI are at increased risk of breastfeeding for a shorter duration, however it is unclear if weight status itself or other factors such as feeding intentions are responsible for early breastfeeding cessation. The aim of this study was determine the influence of maternal pre-pregnancy weight status on infant feeding intentions during pregnancy using a validated scale and assess whether high intentions to exclusively breastfeed measured during pregnancy predicted feeding mode at discharge and at 4 months postpartum in both healthy weight (Hwt) (BMI< 25kg/m(2)) and overweight (Owt)(BMI > 25kg/m(2)) women...

BACKGROUND: Recent studies have indicated that serum levels of squamous cell carcinoma antigen (SCCA) 1 and 2 induced by type 2 cytokines such as IL-4 and IL-13, are increased in patients with atopic dermatitis (AD). However, no clinical studies have analyzed serum levels of SCCA2 in larger series of AD patients or their association with various clinical characteristics. This study was performed to clarify whether serum levels of SCCA2 are associated with disease severity and clinical phenotypes of adult AD patients...

The aim of the present study was to evaluate the influence of rapeseed oilcake used for feeding sheep on the content of fatty acids (FA), tocopherols, retinoids, and cholesterol of milk and cheese, and on the sensory properties of cheese. Indoor animal feeding (in winter) is the highest cost of production for cheesemakers, and the inclusion of locally produced rapeseed oilcake in the concentrate feed formulation can reduce the cost of cheese production, as long as the quality of the cheese is not altered. The experiment was carried out in March (mid lactation) with 72 Latxa sheep from an experimental farm located in the Basque Country (northern Spain)...

REVIEW
Anne M Williams, Parminder S Suchdev
Improving maternal and child nutrition is central to global development goals and reducing the noncommunicable disease burden. Although the process of becoming malnourished starts in utero, the consequences of poor nutrition extend across the life cycle and into future generations. The global nutrition targets for 2025 include reducing infant and young child growth faltering, halting the increase of overweight children, improving breastfeeding practices, and reducing maternal anemia. In this review, we address nutritional assessment, discuss nonnutritive factors that affect growth, and endorse the evidence-based interventions that should be scaled up to improve maternal and child nutrition...

INTRODUCTION: Malignant primary brain tumors are one of the most aggressive cancers. Pretreatment serum nonneuronal biomarkers closely associated with postoperative outcomes are of high clinical relevance. The present study aimed to identify potential pretreatment serum biomarkers that may influence oncological outcomes in patients with primary brain tumors. METHODS: A total of 74 patients undergoing supratentorial primary brain tumor resection were enrolled. Before tumor resection, serum neuronal biomarkers, namely neuron-specific enolase (NSE), S100β, and glial fibrillary acidic protein (GFAP), and serum nonneuronal biomarkers, namely neutrophil gelatinase-associated lipocalin (NGAL), lactate dehydrogenase (LDH), and lactate, were measured and associated postoperative oncological outcomes, including brain tumor grading, progression-free survival (PFS), and overall survival (OS), were compared...

The SV40 transgenic BALB/c mouse based WAP-T/WAP-TNP model for triple-negative breast cancer allows the analysis of parameters influencing immunotherapeutic approaches. Except for WAP-TNP tumors expressing the immune-dominant LCMV NP-epitope within SV40 T-antigen (T-AgNP) which is not expressed by T-Ag of WAP-T tumors, the tumors are extremely similar. Comparative anti-PD1/PD-L1 immunotherapy of WAP-T and WAP-TNP mice supported the hypothesis that the immunogenicity of tumor antigen T-cell epitopes strongly influences the success of immune checkpoint blockade therapy, with highly immunogenic T-cell epitopes favoring rapid CTL exhaustion...

NAD salvage is one of the pathways used to generate NAD in mammals. Nicotinamide phosphoribosyltransferase (NAMPT), the rate-limiting enzyme in this pathway, uses nicotinamide (NAM) to generate nicotinamide mononucleotide (NMN). NMN is one of the main precursors of NAD synthesis in cells. Our previous study showed the importance of NAMPT in maintaining NAD levels in pancreatic ductal adenocarcinoma cells (PDAC), and that the NAMPT inhibitor FK866 decreased pancreatic cancer growth. We now tested the effect of STF-118804, a new highly specific NAMPT inhibitor, in models of pancreatic ductal adenocarcinoma...

LysR-type transcriptional regulators (LTTR) are the most commonly found regulators in Burkholderia cepacia complex, comprising opportunistic pathogens causing chronic respiratory infections in cystic fibrosis (CF) patients. Despite LTTRs being global regulators of pathogenicity in several bacteria, few have been characterized in Burkholderia Here, we showed that gene ldhR of B. multivorans encoding a LTTR is co-transcribed with ldhA encoding a d-lactate dehydrogenase, and evaluate their implication in virulence traits like exopolysaccharide (EPS) synthesis and biofilm formation...

BACKGROUND: Endothelial dysfunction links thrombotic microangiopathy to steroid-refractory graft-versus-host disease (GVHD) after allogeneic stem-cell transplantation. We aimed to assess if the simple formula-lactate dehydrogenase (U/L) × creatinine (mg/dL)/thrombocytes (10(9) cells per L)-termed the Endothelial Activation and Stress Index (EASIX), might be valuable for the prediction of death in patients with acute GVHD after allogeneic stem-cell transplantation. METHODS: For this retrospective analysis, we analysed a training cohort (in Germany) and three validation cohorts (in Germany and the USA) of patients with acute GVHD who had received consecutive allogeneic stem-cell transplantation...

OBJECTIVE: Primary central nervous system (CNS) lymphoma is an aggressive and fatal extranodal non-Hodgkin lymphoma (NHL) jailed in CNS at initial diagnosis. Its prognosis is poor and the disease has a fatal outcome when compared with systemic NHL. A few baseline risk stratification scoring systems have been suggested to estimate the prognosis mainly based on serum lactate dehydrogenase (LDH) level, age, Karnofsky performance score (KPS), involvement of deep brain structures (DBS) and cerebrospinal fluid protein concentration...
