ABSTRACT

Fungal colonization is a common occurrence in preterm neonates. Our objective was to describe the profile and characteristics of fungal colonization in preterm infants admitted to the Martinique NICU. From March 2012 to January 2013, an epidemiological prospective cohort study was conducted with 57 very low-birth-weight infants. Cutaneous, rectal, gastric, respiratory, and urinary swabs were collected on admission, then every week for 4 weeks. The prevalence of fungal colonization was 68% (39/57): 46% by Malassezia species, 28% by Candida parapsilosis, 19% by C. albicans, 5% by C. glabrata, and 2% by C. guilliermondii. The colonized patients had a duration of parenteral nutrition and antibiotic therapy longer than the others (P<0.05). Nosocomial colonization (after 2 days of life) occurred in 52% of cases: Malassezia species and C. parapsilosis were the commensal skin yeasts most frequently implicated. Forty-nine percent (28/57) had suspected invasive fungal infections that received probabilistic treatment. Only one case of invasive fungal infection with C. glabrata was diagnosed. This study highlights the important role played by nosocomial transmission in the colonization of preterm newborns. Mycological surveillance cultures in the NICU are very useful for monitoring fungal ecology and can improve the prevention of fungal colonization in preterm infants at risk of invasive fungal infection.

ABSTRACT

BACKGROUND: Ankylosaurs are one of the least explored clades of dinosaurs regarding endocranial anatomy, with few available descriptions of braincase anatomy and even less information on brain and inner ear morphologies. The main goal of this study is to provide a detailed description of the braincase and internal structures of the Early Cretaceous nodosaurid Pawpawsaurus campbelli, based on recently made CT scans. METHODOLOGY/PRINCIPAL FINDINGS: The skull of Pawpawsaurus was CT scanned at University of Texas at Austin (UTCT). Three-dimensional models were constructed using Mimics 18.0 (Materialise). The digital data and further processed 3D models revealed inaccessible anatomic structures, allowing a detailed description of the lateral wall of the braincase (obscured by other bones in the articulated skull), and endocranial structures such as the cranial endocast, the most complete inner ear morphology for a nodosaurid, and the interpretation of the airflow system within the nasal cavities. CONSLUSIONS/SIGNIFICANCE: The new information on the endocranial morphology of Pawpawsaurus adds anatomical data to the poorly understand ankylosaur paleoneurology. The new set of data has potential use not only in taxonomy and phylogeny, but also in paleobiological interpretations based on the relative development of sense organs, such as olfaction, hearing and balance.

ABSTRACT

BACKGROUND: Accurate risk estimation is essential when benchmarking surgical outcomes for reimbursement and engaging in shared decision-making. The greater complexity of emergency surgery patients may bias outcome comparisons between elective and emergency cases. OBJECTIVE: To test whether an established risk modelling tool, the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) predicts mortality comparably for emergency and elective cases. METHODS: From the ACS-NSQIP 2011-2012 patient user files, we selected core emergency surgical cases also common to elective scenarios (gastrointestinal, vascular, and hepato-biliary-pancreatic). After matching strategy for Common Procedure Terminology (CPT) and year, we compared the accuracy of ACS-NSQIP predicted mortality probabilities using the observed-to-expected ratio (O:E), c-statistic, and Brier score. RESULTS: In all, 56,942 emergency and 136,311 elective patients were identified as having a common CPT and year. Using a 1:1 matched sample of 37,154 emergency and elective patients, the O:E ratios generated by ACS-NSQIP models differ significantly between the emergency [O:E = 1.031; 95% confidence interval (CI) = 1.028-1.033] and elective populations (O:E = 0.79; 95% CI = 0.77-0.80, P < 0.0001) and the c-statistics differed significantly (emergency c-statistic = 0.927; 95% CI = 0.921-0.932 and elective c-statistic = 0.887; 95% CI = 0.861-0.912, P = 0.003). The Brier score, tested across a range of mortality rates, did not differ significantly for samples with mortality rates of 6.5% and 9% (eg, emergency Brier score = 0.058; 95% CI = 0.048-0.069 versus elective Brier score = 0.057; 95% CI = 0.044-0.07, P = 0.87, among 2217 patients with 6.5% mortality). When the mortality rate was low (1.7%), Brier scores differed significantly (emergency 0.034; 95% CI = 0.027-0.041 versus elective 0.016; 95% CI = 0.009-0.023, P value for difference 0.0005). CONCLUSION: ACS-NSQIP risk estimates used for benchmarking and shared decision-making appear to differ between emergency and elective populations.

ABSTRACT

Gondwana landmasses have served as large-scale biogeographic Noah's Arks and Beached Viking Funeral Ships, as defined by McKenna. The latitudinal trajectories of selected Gondwana dinosaur localities were traced through time in order to evaluate their movement through climate zones relative to those in which they originally formed. The dispersal of fauna during the breakup of Gondwana may have been facilitated by the presence of offshelf islands forming landspans (sensu Iturralde-Vinent and MacPhee) in the Equatorial Atlantic Gateway and elsewhere.

ABSTRACT

A forelimb of a new sauropod dinosaur (Angolatitan adamastor n. gen. et sp.) from the Late Turonian of Iembe (Bengo Province) represents the first dinosaur discovery in Angola, and is one of the few occurrences of sauropod dinosaurs in sub-Saharan Africa collected with good chronological controls. The marginal marine sediments yielding the specimen are reported to be late Turonian in age and, thus it represents a non-titanosaurian sauropod in sub-Saharan Africa at a time taken to be dominated by titanosaurian forms. Moreover, Angolatitan adamastor is the only basal Somphospondyli known in the Late Cretaceous which implies in the existence of relict forms in Africa.

As massas de terra do Gondwana serviram como Arcas de Noe biogeograficas de grande escala e Navios Funerarios Vikings encalhados, conforme definido por McKenna. As trajetorias latitudinais de areas selecionadas de dinossauros do Gondwana foram tracadas ao longo do tempo a fim de avaliar seu movimento atraves de zonas climaticas relativas aquelas nas quais elas foram originalmente formadas. A dispersao da fauna durante a quebra do Gondwana pode ter sido facilitada pela presenca de ilhas oceanicas formando extensoes de terra (sensu Iturralde-Vinent e MacPhee) na entrada do Atlantico Equatorial e em outros lugares.

Um membro anterior de um novo dinossauro saurópode (Angolatitan adamastor n. gen. et sp.) do Turoniano Superior de Iembe (Bengo) representa a descoberta do primeiro dinossauro em Angola e é uma das poucas ocorrências de dinossauros saurópodes na África Subsaariana recolhidos com bons controles cronológicos. Os sedimentos marinhos marginais de onde provém o espécime estão datados do Turoniano superior e, portanto, trata-se de um saurópodes não-titanossauro na África subsaariana onde predominavam titanossauros. Além disso, Angolatitan adamastor é o único Somphospondyli basal conhecido no Cretáceo Superior, o que implica a sobrevivência de formas-relíquia na África.

ABSTRACT

PURPOSE: To determine if there are any differences in the zonal distribution and tumor volumes of familial and sporadic prostate cancers (PC) in men undergoing radical prostatectomy. MATERIAL AND METHODS: 839 patients underwent a radical prostatectomy in the absence of prior neoadjuvant therapy between 1987 and 1996. Telephone interviews were conducted to obtain an updated family history. A positive family history was defined as the diagnosis of PC in at least one first degree relative. Prostatectomy specimens were examined to determine the number of tumor foci, zonal origin of the dominant tumor focus, tumor volume of the largest cancer focus, total tumor volume, Gleason score and stage, and the surgical margin status. Results were stratified according to family history and ethnicity. RESULTS: We successfully contacted 437 patients (52%). Prostatectomy specimens from 55 patients were excluded from review due to a history of prior transurethral resection of the prostate (n = 26) or uncertain pathological stage (n = 29). Of the remaining 382 patients, 76 (20%) reported having a first-degree relative with PC. Statistical analysis revealed no significant differences in the pathologic variables between the two groups of patients with or without a family history of PC. CONCLUSIONS: Familial and sporadic PC share similar characteristics. No histopathological differences account for the increased positive predictive value of PC screening tests among patients with a family history of PC.

ABSTRACT

BACKGROUND: Recent anthropological studies have documented the importance of understanding the relation of culture to the experience of mental illness. The use of interviews that elicit explanatory models has facilitated such research, but currently available interviews are lengthy and impractical for epidemiological studies. This paper is a preliminary report on the development of a brief instrument to elicit explanatory models for use in field work. METHOD: The development of the SEMI, a short interview to elicit explanatory models is described. The interview explores the subject's cultural background, nature of presenting problem, help-seeking behaviour, interaction with physician/healer and beliefs related to mental illness. RESULTS: The SEMI was employed to study the explanatory models of subjects with common mental disorders among Whites, African-Caribbean and Asians living in London and was also used in Harare, Zimbabwe. Data from its use in four different ethnic groups is presented with the aim of demonstrating its capacity to show up differences in these varied settings. CONCLUSIONS: The simplicity and brevity of the SEMI allow for its use in field studies in different cultures, data can be used to provide variables for use in quantitative analysis and provide qualitative descriptions.(Au)

ABSTRACT

The authors report a case of a gingival granular cell tumor, also called "congenital epulis", occurring in a female newborn. It is a rare congenital, benign tumor of uncertain histogenesis, with marked predilection for female newborn. The tumor arises, as a polypoid mass, on the gingiva of the anterior maxillary or mandibular alveolar ridge. Typical histologic features are represented by sheets of large cells with pale granular cytoplasm. Despite remarkable similarities between gingival granular cell tumors and others ubiquitous granular cell tumors (granular cell myoblastoma or Abrikossoff's tumor), histogenesis of the gingival granular cell tumors seems different. Unlike those of granular cell myoblastoma, granular cells of gingival granular cell tumor do not express S-100 protein and Neuron-Specific-Enolase. Considering the positivity for oestrogen and progesterone receptors, a hormonal factor may be important in the development of gingival granular cell tumor. The generally accepted treatment is simple excision.
