Determination of sulphur species in solidified cryolite melts
Authors: Ambrová Marta , Jurišová Jana , Fellner Pavel , Thonstad Jomar 
Published: April 2012

AbstractSolidified cryolite melts containing a known amount of Na2SO4 (0–713 mg kg−1 SO42−), Na2S, FeS, and CdS (0–400 mg kg−1 S2−) together with industrial electrolyte samples were tested for the content of sulphate and sulphide ions by ion chromatography. Added and analytically determined contents of sulphate and sulphide were compared and processed by means of linear regression analysis. It was found that the method of ion chromatography yields satisfying results (uncertainty below 1.1 %) and that it is especially suitable for the determination of low content of soluble sulphate or sulphide in solidified cryolite electrolytes. The method can be used for the estimation of insoluble sulphide content in cryolite melts as well. Results of industrial samples analysis showed that the content of sulphate and sulphide in the samples is influenced by their treatment before the analysis.
Adverse effects of antioxidative vitamins
Authors: Rutkowski Maciej , Grzegorczyk Krzysztof 
Published: April 2012

AbstractHigh doses of synthetic antioxidative vitamins: A, E, C and β-carotene are often used on long-term basis in numerous preventive and therapeutic medical applications. Instead of expected health effects, the use of those vitamins may however lead to cases of hypervitaminosis and even to intoxication. The article points out main principles of safety which are to be observed during supplementation with antioxidative vitamins. Toxic effects resulting from erroneous administration of high doses of those substances on organs and systems of the organism are also discussed. Attention is drawn to interactions of antioxidative vitamins with concomitantly used drugs, as well as intensification of adverse effects caused by various exogenous chemical factors. Moreover, the article presents the evaluation of supplementation with these vitamins, which was performed in large studies.
The effect of hydrological connectivity on water beetles fauna in water bodies within the floodplain of a lowland river (Neman river, Belarus)
Authors: Pakulnicka Joanna , Nowakowski Jacek 
Published: April 2012

Abstract
The middle course of the Neman River is the habitat of 120 water beetle species. Water beetles were most abundant in the Neman River, its major tributaries and oxbow lakes. They consisted of four synecological groups: rheobiontic and rheophilic organisms, type “a” and “b” stagnobionts. The diverse types of aquatic environments constitute faunal centers which, in addition to the specific and dominant Coleopteran populations, also feature migrational elements. The presence of close relations between the fauna of different environments indicates that they form a single, faunistically integrated hydrological system.
Mercury distribution in muscles and internal organs of the juvenile and adult Baltic cod (Gadus morrhua callarias Linnaeus, 1758)
Authors: Kwaśniak Justyna , Falkowska Lucyna 
Published: April 2012

Abstract
Cod (Gadus marrhua L), a fish caught in the Baltic Sea, is very popular with consumers. Research on the distribution of mercury in cod tissues and organs was conducted on a group of adult (27) and juvenile (49) individuals in the years 2006–09. Total mercury concentration values in mature cod were always, on average, 1.7 times higher than those in juveniles. The highest HgT concentrations were found in the heart, while the lowest ones were found in the gills and gonads. The essential age-specific differences manifest in a relationship between the mercury concentration in fish muscles and brain. Mature individuals, i.e. of length >80 cm, accumulated Hg in muscles, most likely in an attempt to protect the nervous system from toxic exposure. In young individuals, more mercury was concentrated in the brain than in the muscles.. The distribution of HgT in organs as well as the low value of the [HgT]liver/[HgT]muscle ratio testify to relatively low-level mercury contamination in southern Baltic waters.

Published: April 2012

Purpose: To determine the psychometric properties of the 11-item Tampa Scale for Kinesiophobia (TSK-11) in patients with heterogeneous chronic pain. Methods: The study evaluated test–retest reliability (intra-class correlation coefficient), cross-sectional convergent construct validity (Pearson product–moment correlation between TSK-11 and the Pain Catastrophizing Scale [PCS] scores at admission), and sensitivity to change of the TSK-11 (area under the receiver operating characteristic [ROC] curve) in patients (n=74) with heterogeneous chronic pain. We used two data sets (retrospective, n=56; prospective, n=18). All patients attended the 4-week interdisciplinary chronic pain management programme at Chedoke Hospital, Hamilton Health Sciences, Hamilton, Ontario. Results: The test–retest reliability of the TSK-11 was 0.81 (95% CI, 0.58–0.93), the standard error of measurement was 2.41 (90% CI, 1.47–2.49), and the minimal detectible change score was 5.6. The correlation between TSK-11 and PCS at admission was 0.60 (95% CI, 0.43–0.73). The area under the ROC curve was 0.73 (95% CI, 0.57–0.88). Conclusions: The study results provide evidence for the test–retest reliability, cross-sectional convergent construct validity, and sensitivity to change of the TSK-11 in a population with heterogeneous chronic pain.
Configurations familiales d'hier et d'aujourd'hui
Authors: Lucarelli Daniela , Tavazza Gabriela 
Published: April 2012

Résumé Ce travail se concentre sur les changements familiaux et sur la manière dont ceux-ci se reflètent sur les relations interpersonnelles et produisent des transformations dans les vicissitudes fantasmatiques qui caractérisent la vie mentale individuelle, familiale et de couple. Ces nouvelles configurations, que l’on appelle souvent dans le langage courant « nouvelles familles », nous proposent des fonctions différentes sur le plan tant parental que filial. Dans la psychothérapie psychanalytique de couple, on est de plus en plus souvent confronté à des situations de deuxième union. Dans les nouvelles familles, les deux partenaires portent en eux un travail pénible qui se rapporte au lien précédent. En tant que cliniciennes, nous nous interrogeons sur la manière dont les liens se défont et se refont (sont « déliés » et « reliés ») dans ces nouvelles constellations relationnelles. Le matériel clinique présenté met en lumière ces problématiques.
L'image inconsciente du corps familial
Authors: Cuynet Patrice 
Published: April 2012

Résumé L’auteur propose une analyse théorique de la notion conceptuelle d’image inconsciente du corps familial. Il s’appuie sur ses recherches cliniques en thérapies familiales et sur l’expérimentation d’objets médiateurs tels que le dessin libre de l’arbre généalogique ou celui de la maison imaginaire, faits à grande échelle et sur une population familiale « tout venant ». L’analyse des projections groupales permet de mieux cerner la dynamique structurelle du groupe familial et l’enjeu symptomatique des places individuelles.
Les idéologies économiques du patronat français au 20e siècle
Authors: Denord François 
Published: April 2012

Résumé L’historiographie minimise souvent le rôle intellectuel du patronat. Pourtant, les grandes idéologies (socialisme, libéralisme, etc.) ont nécessairement partie liée avec la dévolution du pouvoir dans la sphère économique et au sein de l’entreprise. En ces matières, le patronat ne saurait être neutre. L’organisation de la production, la direction de l’entreprise, les formes de régulations économiques et sociales acceptables suscitent en son sein des controverses et nourrissent des visions du monde contrastées. Le 20 e siècle a ainsi vu les idéologies économiques patronales se transformer d’un point de vue théorique et organisationnel. Le libéralisme s’est clairement imposé dans la bataille des idées, tandis que les doctrines rivales, comme le corporatisme, passent désormais pour surannées. Parallèlement, le patronat s’est professionnalisé sur le plan de la production idéologique, en mettant en place des structures spécialisées et en recourant massivement à des experts.
How pseudo is an inflammatory pseudotumor?
Authors: Gude Dilip , Rayudu Ramasubba , Bansal Dharam 
Published: April 2012

AbstractInflammatory pseudotumor (IPT) is a rare lesion of unclear etiology reported in various organs. Although mostly benign, these tumors may pose a therapeutic challenge in cases of recurrence. We report the case of a young male who presented with a clinical and radiological picture suggestive of a malignancy in the thorax and upon evaluation was noted to have IPT of the lung. Complete surgical resection was done with no evidence of tumor recurrence. We review the literature and discern the epidemiological, clinical, pathophysiological and management aspects of IPTs.

Published: April 2012

AbstractOvarian involvement as primary or secondary lymphomatous process is extremely uncommon. In most cases, the diagnosis is usually not suspected initially and is confirmed only after detailed histopathological evaluation. We report a patient with primary ovarian diffuse large B-cell lymphoma (DLBCL) and associated auto-immune hemolytic anemia (AIHA) who achieved complete remission after treatment with Rituximab-cyclophosphamide-doxorubicin-vincristine and prednisolone (R-CHOP) chemotherapy. This patient was a 50 year old female, who presented with fever, abdominal pain, vomiting, weight loss and anemia. Computed tomography scan of the abdomen and pelvis revealed a large left ovarian mass with bilateral hydronephrosis. We performed exploratory laparotomy and partial resection of the mass was done due to the adhesions. Histopathology confirmed the diagnosis of DLBCL. After six R-CHOP chemotherapy cycles, patient achieved complete response with correction of anemia. To our knowledge, this may be the first case report till date of primary ovarian DLBCL with AIHA treated with R-CHOP chemotherapy who achieved complete remission in terms of primary disease as well as hemolytic anemia.
Isolated cerebellar involvement in posterior reversible encephalopathy syndrome in a child with acute lymphoblastic leukemia
Authors: Chaudhary Narendra , Majeed Rubeena , Borker Anupama 
Published: April 2012

AbstractParieto-occipital region is the most commonly involved site in posterior reversible encephalopathy syndrome (PRES). Cerebellar involvement has been reported with the predominant involvement of posterior cerebral regions, but isolated cerebellar involvement in PRES has been reported only once in English literature. We report here a 7-year-old boy with acute lymphoblastic leukemia who had PRES with isolated cerebellar involvement during induction chemotherapy. He presented with sudden onset headache, vomiting and hypertension followed by seizures, unconsciousness, and involuntary movements. Computed tomography scan revealed bilateral cerebellar hypodensities. He improved within few hours and reversibility of the lesions was documented on magnetic resonance imaging after 2 weeks. Awareness of atypical patterns in distribution of imaging abnormalities is important to recognize PRES more accurately and to avoid unnecessary diagnostic procedures and treatment.
Is antenatal detection of Wilms′ tumor a bad prognostic marker?
Authors: Jain Vishesh , Mohta Anup , Sengar Mamta , Khurana Nita 
Published: April 2012

AbstractAntenatal detection of Wilms′ tumor is rare and only nine cases have been reported till now in the English literature. We report a case of a 7-month-old child with prenatally detected renal mass managed by nephroureterectomy associated with intraoperative spill. The child developed recurrence while on DD4A chemotherapy. Salvage chemotherapy was initiated but there was no response after two cycles and the child expired due to tumor rupture.
Risky Pursuits: Martu Hunting and the Effects of Prey Mobility: Reply to Ugan and Simms
Authors: Bird Douglas W. , Codding Brian F. , Bliege Bird Rebecca , Zeanah David W. 
Published: April 2012

AbstractWe recently demonstrated that prey size is not a reliable predictor of post-encounter return rates for resources Martu hunters regularly handle in Australia’s Western Desert (Bird et al. 2009). Ugan and Simms are skeptical of our calculations of these returns, especially in our inclusion of tracking as pursuit time. Here we review how these variables were recorded and calculated, update the analysis with more data, and clarify the importance of prey mobility and pursuit failures for understanding the contexts of hunting decisions and their archaeological implications.
Childhood Lost: Abductions, Sacrifice, and Trophy Heads of Children in the Wari Empire of the Ancient Andes
Authors: Tung Tiffiny A. , Knudson Kelly J. 
Published: April 2012

AbstractThis study examines isolated child skeletal remains from ritual structures at the Wari site of Conchopata (A.D. 600–1000) to evaluate how they were modified into trophy heads and whether the children were sacrificed. The skeletal remains represent at least seven children. Strontium isotope ratios are examined to determine whether children were taken from foreign locales. Results show that the children’s skulls exhibit a hole on the apex of the cranium and on the ascending ramus of the mandible, identical to the adult Wari trophy heads. At least one child may have been sacrificed.87Sr/86Sr demonstrate that two of the four sampled child trophy heads were nonlocal, suggesting that children were occasionally abducted from distant communities, perhaps for sacrifice and certainly to transform some into trophy heads. The similar child and adult trophy heads suggest that the ritual treatment of children was not uniquely designed, at least as it related to their processing, display, and destruction. Furthermore, it is suggested that the child trophy heads were not simply passive symbols of pre-existing authority by the head-takers and trophy head-makers. The trophy heads simultaneously imbued those agents with authority—they did not merely reflect it—demonstrating the “effective agency” of the trophy head objects themselves. Finally, we suggest that prisoner-taking and trophy head-making by military and ritual elites served to legitimate the authority of those individuals while simultaneously serving larger state goals that enhanced Wari state authority and legitimated its policies and practices.
Building Chan Chan: A Project Management Perspective
Authors: Smailes Richard L. 
Published: April 2012

AbstractThe labor investment in ancient monumental architecture is an important factor in hypotheses concerning a society’s size, organization, and social complexity. Most methods of quantifying labor expenditures are limited to simply designed structures with a minimal number of elements. Due to the lack of practical analytical methods, complex architecture is often described subjectively, offering little quantitative value, resulting in inferences that could be misleading or wrong. Using Ciudadela Rivero at the site of Chan Chan, Peru, as a case study, this research employed construction industry-standard planning, estimating, and scheduling tools to calculate the labor requirements and construction times under various building scenarios. Additionally, the application of Critical Path Method scheduling provides the means to model and compare numerous building scenarios by simulating the effects of various construction and labor organization strategies in their cultural context. The results for Ciudadela Rivero revealed a labor input of over two million labor hours, which could be accomplished by a modest labor force of as few as 250 workers over a six-year period. These data affect numerous archaeological hypotheses concerning scale of construction, organization of labor, and complexity of social organization.
The Domestication and Early Spread of Manioc (Manihot EsculentaCrantz): A Brief Synthesis
Authors: Isendahl Christian 
Published: April 2012

AbstractOwing to poor preservation of organic remains in humid environments, direct evidence of early manioc (Manihot esculentaCrantz) cultivation is exceptionally rare in datable archaeological contexts. Recent research summarized here offers new insights into the spatio-temporal framework of the initial domestication and early spread of manioc in the Neotropics. Integrating evidence from comparative plant genetics and paleoethnobotanic starch analysis to contribute to the archaeology of manioc origins, this review finds that (1) the strongest candidate for the botanical origin of domesticated manioc—the wild progenitor of the root crop—is the species Manihot esculenta subspeciesflabellifolia(Pohl)Ciferri; (2) the geographical origin of manioc—the biome in which the progenitor evolved—is most likely in the savannas, the Brazilian Cerrado, to the south of the Amazon rainforest; (3) the Cerrado is also, in our best estimate, the region of agricultural origin of initial cultivation; (4) domesticated manioc had spread from the agricultural origin by the early Holocene, possibly as early as 10,000 years ago, but certainly by 7000 B.C.; and (5) domesticated manioc was a readily available plant in most habitats of the Neotropics by the mid-Holocene, at least some 6500 years ago.
Interpretations of Pre-Hispanic Ritual Violence at Tucume, Peru, from Cut Mark Analysis
Authors: Toyne J. Marla 
Published: April 2012

AbstractArchaeological residues of ritual are often ephemeral, and reconstructing the dynamics of performed actions that create deposits can be difficult. Rituals associated with the dead are common across many cultures since all human groups have specific means of disposing of corpses. Evidence of peri- and postmortem manipulation of human remains, such as cutting, dismemberment, or disarticulation can provide details of the sequence of actions performed related to the circumstances surrounding death and the possible social meaning of those behaviors. Cut marks observed on the upper chest and throat of 93 percent of 117 children and men found interred at the Temple of the Sacred Stone at Túcume, Peru are consistent with three symbolic behaviors: cutting the throat, opening the chest cavity, and decapitation. This patterning of skeletal trauma demonstrates that a highly elaborate series of violent ritual behaviors was carried out on a regular basis at this location, beginning in the Late Intermediate Period (∼A.D. 1100) through to the end of the Late Horizon Inca occupation of the site around A.D. 1532. The recent finds of bioarchaeological evidence of ritual violence across the Andes suggests that, although rare, these mortuary remains provide important clues to the elaborate nature of ritual behaviors at different sites.
Eating Fish in the Driest Desert in the World: Osteological and Biogeochemical Analyses of Human Skeletal Remains from the San Salvador Cemetery, North Chile
Authors: Torres-Rouff Christina , Pestle William J. , Gallardo Francisco 
Published: April 2012

AbstractThe San Salvador River in northern Chile is a tributary of the Loa, the only river that traverses the Atacama Desert from the mountains to the Pacific. Recent investigations along the San Salvador River revealed the presence of a Formative period village site and associated cemetery approximately 110 km inland from the Pacific Ocean. Bioarchaeological and biogeochemical analyses conducted on human skeletal remains recovered from the San Salvador Cemetery allowed us to better understand the site’s role as an intermediary for coast/interior relations during the Middle Formative (500 B.C.–A.D. 100). Evidence from material culture and human remains at San Salvador suggests that this population was involved in exchange networks that united the oases of the Atacama Desert with the Pacific Ocean. Isotopic data support this notion, as the population demonstrates great variability in both the protein (marine and terrestrial) and carbohydrate components of their diet. During this period, communal economies produced surpluses used in a network of exchange for foods, prestige goods, and ideas. These ties were not coincidental but, rather, part of a regional economic structure that remains only partly explored.
Interventions for Weight Management in Children and Adolescents

Published: June 2024

ImportanceBody mass index (BMI) of the 95th or greater percentile for age and sex is common among young people, and its prevalence has increased in recent decades.ObjectiveTo examine the benefits and harms of weight management interventions initiated in health care settings among children and adolescents with high BMI.Data SourcesMEDLINE via Ovid, PsycINFO via Ovid, and the Cochrane Central Registry of Controlled Trials through January 12, 2023; ongoing surveillance through January 26, 2024.Study SelectionEnglish-language studies of weight management interventions (behavioral and pharmacologic, including liraglutide, semaglutide, orlistat, and phentermine/topiramate) among children aged 2 to 18 years with high BMI (eg, ≥85th or ≥95th percentile for age and sex) conducted in or recruited from health care settings.Data Extraction and SynthesisOne investigator abstracted data; a second checked for accuracy. Outcomes with sufficient evidence for meta-analysis were pooled using random-effects models.Main Outcomes and MeasuresBMI and other weight-related outcomes, cardiometabolic measures, quality of life, physical activity, dietary pattern scores, and harms.ResultsFifty-eight randomized clinical trials (RCTs) were included (N = 10 143). Behavioral interventions were associated with small reductions in BMI and other weight outcomes after 6 to 12 months (28 RCTs [n = 4494]; mean difference in change between groups, −0.7 [95% CI, −1.0 to −0.3]). Larger effects were seen in interventions with higher contact hours and that offered physical activity sessions. Reporting was sparse for outcomes other than BMI, with few significant findings. Semaglutide and phentermine/topiramate had the largest effects on BMI (eg, 1 RCT [n = 201] for semaglutide; mean difference, −6.0 [95% CI, −7.3 to −4.6]). The very few studies that evaluated outcomes after medication discontinuation showed immediate weight regain. Gastrointestinal adverse effects were common with liraglutide, semaglutide, and orlistat. Serious adverse effects were rare, but no studies had follow-up longer than 17 months.Conclusions and RelevanceIn the short term, weight management interventions led to lower BMI in children and adolescents, with no evidence of serious harm. Evidence is lacking about how weight management interventions affect BMI beyond 1 year and after medication discontinuation and about longer-term effects on other outcomes.
