Discovering, Defining, and Summarizing Persistent Hotspots in SCORE Studies

Abstract. The Schistosomiasis Consortium for Operational Research and Evaluation (SCORE) conducted large field studies on schistosomiasis control and elimination in Africa. All of these studies, carried out in low-, moderate-, and high-prevalence areas, resulted in a reduction in prevalence and intensity of Schistosoma infection after repeated mass drug administration (MDA). However, in all studies, there were locations that experienced minimal or no decline or even increased in prevalence and/or intensity. These areas are termed persistent hotspots (PHS). In SCORE studies in medium- to high-prevalence areas, at least 30% of study villages were PHS. There was no consistent relationship between PHS and the type or frequency of intervention, adequacy of reported MDA coverage, and prevalence or intensity of infection at baseline. In a series of small studies, factors that differed between PHS and villages that responded to repeated MDA as expected included sources of water for personal use, sanitation, and hygiene. SCORE studies comparing PHS with villages that responded to MDA suggest the potential for PHS to be identified after a few years of MDA. However, additional studies in different social-ecological settings are needed to develop generalizable approaches that program managers can use to identify and address PHS. This is essential if goals for schistosomiasis control and elimination are to be achieved.
Brain Structural Plasticity Associated with Maternal Caregiving in Mothers: A Voxel- and Surface-Based Morphometry Study

Background: Pregnancy constitutes a significant period in the lives of women, after which they often experience numerous crucial physiological and psychological changes. Functional neuroimaging studies have shown longitudinal changes in functional brain activity in mothers responding to infant-related stimuli. However, the structural changes that occur in the brains of mothers after delivery remain to be explored. Objective: We aimed to evaluate the structural changes in mothers during the postpartum phase. Methods: We recruited 35 primiparous mothers and 26 nonmothers to participate in this voxel- and surface-based morphometry study, and 22 mothers were scanned twice with a follow-up of approximately 2 years. Results: Compared to nonmothers, mothers exhibited reduced gray matter (GM) volumes and increased white matter (WM) volumes in regions associated with empathy and reward networks (supplementary motor area, precuneus, inferior parietal lobe, insula, and striatum), decreased cortical thickness in the precentral gyrus and increased gyrification index in the orbitofrontal cortex. Furthermore, mothers showed longitudinal changes in the GM and WM volumes and cortical thickness of several of these regions (including the superior and medial frontal gyrus, insula, limbic lobe, superior and middle temporal gyrus, and precentral gyrus), which have been associated with maternal networks during the postpartum period. Additionally, the changes in GM and WM volumes were related to changes in empathetic abilities in mothers. Conclusion: These results suggest that the brains of mothers exhibit adaptive structural dynamic plasticity. These findings provide a neuroanatomical basis for understanding how mothers process emotional sensory information during the postpartum period.
Carboxylic Acid Transporters in Candida Pathogenesis

Opportunistic pathogens such as Candida species can use carboxylic acids, like acetate and lactate, to survive and successfully thrive in different environmental niches. These nonfermentable substrates are frequently the major carbon sources present in certain human body sites, and their efficient uptake by regulated plasma membrane transporters plays a critical role in such nutrient-limited conditions. Here, we cover the physiology and regulation of these proteins and their potential role in Candida virulence. ABSTRACT Opportunistic pathogens such as Candida species can use carboxylic acids, like acetate and lactate, to survive and successfully thrive in different environmental niches. These nonfermentable substrates are frequently the major carbon sources present in certain human body sites, and their efficient uptake by regulated plasma membrane transporters plays a critical role in such nutrient-limited conditions. Here, we cover the physiology and regulation of these proteins and their potential role in Candida virulence. This review also presents an evolutionary analysis of orthologues of the Saccharomyces cerevisiae Jen1 lactate and Ady2 acetate transporters, including a phylogenetic analysis of 101 putative carboxylate transporters in twelve medically relevant Candida species. These proteins are assigned to distinct clades according to their amino acid sequence homology and represent the major carboxylic acid uptake systems in yeast. While Jen transporters belong to the sialate:H+ symporter (SHS) family, the Ady2 homologue members are assigned to the acetate uptake transporter (AceTr) family. Here, we reclassify the later members as ATO (acetate transporter ortholog). The new nomenclature will facilitate the study of these transporters, as well as the analysis of their relevance for Candida pathogenesis.
Host size induced variation in progeny sex ratio of an aphid parasitoid Lysiphlebia mirzai

A study aimed at determining the effect of host size on the pattern of sex allocation by an aphid parasitoid Lysiphlebia mirzai Shuja‐Uddin (Hymenoptera: Braconidae: Aphidiinae) was undertaken to test the validity of the following three hypotheses: (1) larger hosts will yield a greater proportion of daughters, (2) differential mortality of the sexes of the parasitoid during development is a function of host‐size, and (3) daughters emerging from larger hosts are more fecund. The results suggested a propensity in the parasitoid to deposit fertilised (diploid) eggs in large hosts (third instar nymph) and unfertilised (haploid) eggs in small hosts (first and second instar nymphs). Unpreferred fourth instar nymphs and apterous aphid adults also received more haploid eggs despite being larger in size than the preferred third instar nymphs. However, the perception of host size by the mother was dependent on the extent of temporal variation in the host size distribution and on her previous experience of host size. Developmental period, longevity, mating potential, fecundity and progeny sex ratio of L. mirzai emerging from small versus large hosts indicated that the host size affected the fitness of the daughters more than that of sons. No differential mortality of the sexes during development of L. mirzai was observed in small versus large hosts. This shows that L. mirzai, while ovipositing in growing stages of the host, adjusts progeny sex ratio according to the host size and by doing so she tends to contribute maximally to progeny fitness without knowing about the future host quality.
Surgical resection of metastatic pancreatic cancer: is it worth it?-a 15-year experience at a single Chinese center.

Background The significance of surgical resection in the treatment of metastatic pancreatic ductal adenocarcinoma (PDAC) is currently unclear. This study aimed to summarize and clarify the experience of surgical treatment of M1 PDAC in our center and evaluate whether it may offer benefits to some metastatic PDAC patients. Methods We analyzed the data of the patients with M1 PDAC who underwent synchronous tumor resection between 2003 and 2014 at Ruijin Hospital. Simultaneously, clinical data for M1 PDAC patients who underwent palliative bypass or exploratory laparotomy only was also collected during the same period as control. Every patient was followed up at least 3 years after hospitalization. The follow-up endpoint was December 31, 2017. Results A total of 36 patients underwent synchronous tumor resection; of them, 7 received postoperative adjuvant chemotherapy. Their 1-, 2-, and 3-year survival rates were 27.3%, 21.2%, and 7.1%, respectively, and the overall survival was 7.9 months. The overall survival of the palliative bypass and exploratory laparotomy groups was only 4 and 3.7 months, respectively (P<0.05). Conclusions It is unclear whether synchronous tumor resection can benefit M1 PDAC patients due to tumor heterogeneity and differences in tumor burden. However, our current experience indicated that synchronous tumor resection can be safely performed and might be appropriate for some highly selected patients due to the relatively longer survival time. Combined (neo)adjuvant chemotherapy would further prolong overall survival in these patients.
Evaluation of the Efficacy of Prolonged Pregabalin Administration Before and After Surgery in Patients Undergoing Arthroscopic Anterior Cruciate Ligament Repair

Context and Objective: Reconstruction of the knee ligament causes postoperative pain and delayed rehabilitation. Objective: The primary objective of this study was to evaluate the effect of a prolonged preoperative and postoperative pregabalin use for arthroscopic anterior cruciate ligament repair. Materials and Methods: Group 1 (N=25) patients received pregabalin 75 mg/d, and group 2 (N=25) received placebo, 7 days before and 7 days after surgery. Spinal anesthesia was performed using 0.5% hyperbaric bupivacaine (15 mg). The following were evaluated: pain intensity immediately after the surgery, and 12 hours, 24 hours, 1 week, 2 weeks, 1 month, and 2 months after the surgery using a Numerical Rating Scale; dose of postoperative supplementary analgesic for 2 months; time to first analgesic requirement; and side effects during 2 months. For supplementation, the participants received 1 g dipyrone; if there was no pain control, 100 mg ketoprofen was administered; if there was no effect, 100 mg tramadol was administered; and if there was no pain control, 5 mg intravenous morphine was administered until pain control. Results: There was no difference between the groups with regard to pain intensity (P=0.077). In the pregabalin group, morphine consumption was lower at 12 hours (P=0.039) and 24 hours (P=0.044) after surgery, and the consumption of tramadol and ketoprofen was lower 24 hours after surgery. There was no significant difference in the incidence of nausea and vomiting. Dizziness was higher in the pregabalin group (group 1=12 patients; group 2=3 patients; P=0.005). Discussion: A prolonged preoperative and postoperative pregabalin prescription for anterior cruciate ligament repair decreased the need for supplementary analgesics during the first 24 postoperative hours but increased dizziness.
Stability of Glutaraldehyde in Biocide Compositions

Glutaraldehyde (GA) is used as biocide in hospitals. Recent public investigations on the chemical composition of biocides used in Romania have in some cases found GA, as a key ingredient, to be apparently diluted. However, these data did not explicitly consider the complex chemical equilibria inherent to GA. An investigation of experimental and theoretical data is reported here, assessing the stability of GA solutions relevant for biocide compositions. GA solutions of various chemical composition and under varying circumstances were analyzed using spectroscopy (UV-VIS, Raman, NMR) coupled with density functional theory (DFT) calculations, as well as chemically, such as via the formation of imines in reaction/titration with glycine monitored at 270 nm; using LC-MS; or using SDS-PAGE analysis with GA as reagent in the polymerization of two test proteins- hemoglobin and myoglobin. The spectral properties of GA changed significantly over time, in a temperature-dependent manner; titration with glycine confirmed the spectral data. SDS-PAGE experiments demonstrated a non-linear and apparently unpredictable change in the reactivity of GA over time. The results may be relevant for the determination of GA concentration in various settings such as biocide analysis, hospital wastewaters, and others.
L-Ascorbic Acid Inhibits Breast Cancer Growth by Inducing IRE/JNK/CHOP-Related Endoplasmic Reticulum Stress-Mediated p62/SQSTM1 Accumulation in the Nucleus

Anticancer effects of L-ascorbic acid (Vitamin C, L-AA) have been reported in various types of cancers. L-AA intake reduces breast cancer recurrence and mortality; however, the role of L-AA in the treatment of breast cancer remains poorly understood. In this study, we investigated the effect and mechanism action of L-AA on breast cancer growth. L-AA inhibited the growth of breast cancer cells by inducing apoptotic cell death at the evaluated treatment concentrations without affecting normal cells. Moreover, L-AA induces autophagosome formation via regulation of mammalian target of rapamycin (mTOR), Beclin1, and autophagy-related genes (ATGs) and increased autophagic flux. Notably, we observed that L-AA increased p62/SQSTM1 (sequestosome 1) protein levels. Accumulation of p62 protein in cancer cells in response to stress has been reported, but its role in cancer regulation remains controversial. Here, we demonstrated that L-AA-induced p62 accumulation is related to L-AA-induced breast cancer growth inhibition. Furthermore, L-AA induced endoplasmic reticulum (ER) stress via the IRE–JNK–CHOP (inositol-requiring endonuclease–c-Jun N-terminal kinase–C/EBP homologous protein) signaling pathways, which increased the nuclear levels of p62/SQSTM1. These findings provide evidence that L-AA-induced ER stress could be crucial for p62 accumulation-dependent cell death, and L-AA can be useful in breast cancer treatment.
The sonar beam of Macrophyllum macrophyllum implies ecological adaptation under phylogenetic constraint

ABSTRACT All animals are adapted to their ecology within the bounds of their evolutionary heritage. Echolocating bats clearly show such adaptations and boundaries through their biosonar call design. Adaptations include not only the overall time-frequency structure, but also the shape of the emitted echolocation beam. Macrophyllum macrophyllum is unique within the phyllostomid family, being the only species to predominantly hunt for insects in the open, on or above water, and as such it presents an interesting case for comparing the impact of phylogeny and ecology as it originates from a family of low-intensity, high-directionality gleaning bats, but occupies a niche dominated by very loud and substantially less-directional bats. Here, we examined the sonar beam pattern of M. macrophyllum in the field and in a flight room and compared it to closely related species with very different feeding ecology and to that of the niche-sharing but distantly related Myotis daubentonii. Our results show that M. macrophyllum uses higher source levels and emits less-directional calls than other phyllostomids. In the field, its call directionality is comparable to M. daubentonii, but in the flight room, M. macrophyllum is substantially more directional. Hence our results indicate that ecology influences the emitted call, pushing the bats to emit a louder and broader beam than other phyllostomids, but that phylogeny does limit the emitted intensity and flexibility of the overall beam pattern. Summary: The long-legged bat (Macrophyllum macrophyllum) emits broader and more intense echolocation calls than its close relatives, but these are still less intense and have less flexibility in the emitted beam than ecologically similar vespertilionid bats.
Possible Protective Effects of TA on the Cancerous Effect of Mesotrione

The interaction of different food ingredients is now a very important and often emerging topic of research. Pesticides and their breakdown products, which may be carcinogenic, are one of the frequently occurring food contaminants. Compounds like traumatic acid (TA), which originates from plants, are beneficial, antioxidant, and anticancer food ingredients. Previously obtained results from our research group indicated antioxidative in normal human fibroblasts and prooxidative in cancer cells activity of TA. Since the literature data show an undoubted connection between the presence of pesticides in food and the increased incidence of different types of cancers, we attempted to clarify whether TA can abolish the effect of mesotrione stimulating the growth of cancer cells. In order to study the influence of mesotrione on breast cancer cells, we decided to carry out cytotoxicity studies of environmentally significant herbicide concentrations. We also analyzed the cytotoxicity of TA and mixtures of these two compounds. After selecting the most effective concentrations of both components tested, we conducted analyses of oxidative stress parameters and apoptosis in ZR-75-1 cells. The obtained results allow us to conclude that traumatic acid by stimulating oxidative stress and apoptosis contributes to inhibiting the growth and development of cells of the ZR-75-1 line strengthened by mesotrione. This may mean that TA is a compound with pro-oxidative and proapoptotic effects in cancer cells whose development and proliferation are stimulated by the presence of mesotrione. The presented results may be helpful in answering the question of whether herbicides and their residues in edibles may constitute potential threat for people diagnosed with cancer and whether compounds with proven pro-oxidative effects on cancer cells can have potential cytoprotective functions.
Regional Variation in Transient Ischemic Attack and Minor Stroke in Alberta Emergency Departments

Background and Purpose— Multiple studies have shown the 90-day risk of stroke following an emergency department (ED) diagnosis of transient ischemic attack (TIA) or minor stroke is significant, with the greatest risk of recurrence being within the first 24 to 48 hours following initial symptom onset. This study explored regional differences in ED disposition, neuroimaging, and subsequent 90-day stroke risk of patients diagnosed with TIA or minor stroke in Alberta. Methods— We used administrative databases to identify ED visits, neuroimaging, and 90-day return visits for TIA or minor stroke in Alberta from April 2011 to March 2016 among adults ≥20 years of age and stratified them based on regions of presentation (Edmonton, Calgary, or nonmajor urban). Results— During the 5-year study period, 22 421 patients had index ED visits for TIA or minor stroke. All 3 regions had a similar number of ED visits for TIA/minor stroke; however, on index ED visit, Calgary had a higher proportion of computed tomographic angiography imaging (48.8%; P<0.0001) compared with Edmonton (6.7%) and nonmajor urban region (5.7%) and higher proportion of discharged patients (83%; P<0.0001) compared with Edmonton (77.7%) and nonmajor urban region (73.5%). The risk of admission for stroke within 90 days of discharge after index ED visit for TIA/minor stroke in Calgary (3.4%) was lower than Edmonton (4.5%) and the nonmajor urban region (4.6%; P=0.002). Conclusions— This study demonstrates regional variation in computed tomographic angiography for neurovascular imaging of patients presenting to the ED for TIA/minor stroke and a possible association with frequency of index visit admission and 90-day readmission for the same problem.
Influences of Liming on Vertisol Properties and Yields of The Field Crops

The field experiment with fertilizer „Njival Ca“ (waste of the Serbian glas factory in Paracin: calcite 98.5% CaCO 3 , granulation <0.1 mm) was conducted in spring 1998 on the Kragujevac vertisol with the treatments as follows (t ha −1 on CaCO 3 basis): 0 (the control), 0.8 and 1.6 (every year), 4.0 and 8.0 (at start of the experiment). The trial was conducted in five replicates and in triplicate for wheat-maize-soybean roration. In general, limiting considerably influenced on yields of the field crops and single application of the high rates are better choice in comparison with repeated use of the low rates. For example, by yield increases in comparison with the control were as follows (comparison single application of 8 t ha −1 and repeated applications of 1.6 t ha −1 ): 29% and 9% (maize), 7% and 3% (wheat), 24% and 9% (soybean), respectively.
Transient and lineage-restricted requirement of Ebf3 for sternum ossification

ABSTRACT Osteoblasts arise from bone-surrounding connective tissue containing tenocytes and fibroblasts. Lineages of these cell populations and mechanisms of their differentiation are not well understood. Screening enhancer-trap lines of zebrafish allowed us to identify Ebf3 as a transcription factor marking tenocytes and connective tissue cells in skeletal muscle of embryos. Knockout of Ebf3 in mice had no effect on chondrogenesis but led to sternum ossification defects as a result of defective generation of Runx2+ pre-osteoblasts. Conditional and temporal Ebf3 knockout mice revealed requirements of Ebf3 in the lateral plate mesenchyme cells (LPMs), especially in tendon/muscle connective tissue cells, and a stage-specific Ebf3 requirement at embryonic day 9.5-10.5. Upregulated expression of connective tissue markers, such as Egr1/2 and Osr1, increased number of Islet1+ mesenchyme cells, and downregulation of gene expression of the Runx2 regulator Shox2 in Ebf3-deleted thoracic LPMs suggest crucial roles of Ebf3 in the onset of lateral plate mesoderm differentiation towards osteoblasts forming sternum tissues. Highlighted Article: Analysis of conditional and temporal knockout mice reveals roles of Ebf3 in the differentiation of lateral plate mesenchymal cells towards pre-osteoblasts during sternum ossification at the boundary of the lateral and somitic mesoderm.
Quality of Life among Compound Caregivers and Noncompound Caregivers of Adults with Autism

ABSTRACT Children diagnosed with autism spectrum disorder (ASD) are reaching adulthood and require some form of lifelong care. Many parents continue caring for their adult children with ASD for as long as physically possible. As parents age, many also may provide care for another loved one, such a spouse or parent. This study compares compound (those providing care for multiple loved ones) and noncompound parental caregivers (those providing care solely for an adult child with ASD) on six dimensions of quality of life (enjoys life, life is meaningful, ability to concentrate, accepts bodily appearance, satisfied with self, and frequency of negative feelings). Specifically, this study determined the extent to which compound and noncompound caregivers’ quality of life differed. The present study included 320 parents (age 50 or older) of adult children (18 or older) diagnosed with ASD who completed a web-based survey. T-tests for independent samples compared the six dimensions and overall quality of life between compound and noncompound caregivers. Results indicated that compound caregivers were less able to concentrate and had fewer negative feelings than noncompound caregivers. Further research is needed to determine the effects of caregiving on the multidimensional aspects of quality of life.
