The phase III Transfusion and Treatment of severe anaemia in African Children Trial (TRACT) found that conservative management of uncomplicated severe anaemia [haemoglobin (Hb) 40-60 g/l] was safe, and that transfusion volume (20 vs. 30 ml/kg whole blood equivalent) for children with severe anaemia (Hb 37·5°C). In 2020 a stakeholder meeting of paediatric and blood transfusion groups from Africa reviewed the results and additional analyses. Among all 3196 children receiving an initial transfusion there was no evidence that nutritional status, presence of shock, malaria parasite burden or sickle cell disease status influenced outcomes or modified the interaction with fever status on volume required. Fever status at the time of ordering blood was a reliable determinant of volume required for optimal outcome. Elevated heart and respiratory rates normalised irrespective of transfusion volume and without diuretics. By consensus, a transfusion management algorithm was developed, incorporating three additional measurements of Hb post-admission, alongside clinical monitoring. The proposed algorithm should help clinicians safely implement findings from TRACT. Further research should assess its implementation in routine clinical practice.

Occult lymph metastasis is an important prognosticator for the treatment of early oral tongue squamous cell carcinoma (SCC). The objective of this study was to evaluate the prognostic significance of tumor-infiltrating lymphocytes (TILs) in early oral tongue SCC. The combination of the TIL subtype and intermediate- or high-grade budding scores was investigated as a prognostic marker for occult neck metastases.

Retrospective study.

Specimens from 62 patients with early oral tongue SCC treated with only primary surgery were analyzed by immunohistochemistry for CD4+, CD8+, FoxP3+, and CD45RO+ T cells and CD163+ macrophages. Crenolanib chemical structure The highest number of each TIL subtype was counted in two areas of parenchyma and stroma in the tumor (Tumor) and peripheral stroma of the invasion margin.

Based on multivariate analysis, a high density of Tumor CD163+ macrophages served as the poorest prognostic factor for regional control (RC) and disease-free survival (DFS). Patients with both a high density of Tumor CD163+ macrophages and an intermediate- or a high-grade budding score had a poor prognosis for RC according to the log-rank test.

In summary, each TIL subtype may use different mechanisms during early and advanced stages of oral tongue SCC. A high density of Tumor CD163+ macrophages was determined to be a risk factor for RC and DFS as well as an additional stratification factor for RC in patients with intermediate- or high-grade budding scores. Therefore, identifying TIL subtypes in daily clinical practice can help determine a more successful and individualized therapeutic approach for early oral tongue SCC.

Step 4 (Level 4) Laryngoscope, 2021.

Step 4 (Level 4) Laryngoscope, 2021.We identified 43 cases of mutilation homicides in a nationwide population-based study in Sweden during the period of 1991-2017. 70% of cases were classified as defensive mutilations where the main motive was disposal of the body, while 30% were classified as offensive, that is, due to an expression of strong aggression, necro-/sexual sadism, or psychiatric illness. In comparison with a previous study covering mutilation homicides in Sweden between 1961 and 1990, we noted an increase in incidence. The percentage of cases involving mutilation had increased from 0.5% of all homicides in the 1960s to 2.4% in the 2010s. The most common cause of death was sharp force, but in 28% of the cases, the cause of death could not be determined. The clearance rate in cases of mutilation homicide was 67%, and in a large majority of the cases, the offender was known to the victim. With regards to gender women made up 44% of the victims, whilst men constituted 56% of the victims and a total of 95% of the offenders. Half of the offenders had a personality disorder, however, only 13% were sentenced to forensic psychiatric care.As part of a larger project on contextual factors of mass murder, this paper identifies and discusses four cases that quite clearly suggest, based on the content of perpetrators' personal communications and/or reports from those who knew them, that the perpetrators purposely planned and experienced their attacks as desired leisure experience. Leisure science, while consistent with the multidisciplinary roots of forensic behavioral science, has not yet been applied to better understand cases of mass violence. Together with traditional forensic behavioral science approaches, leisure theory may produce insights in cases of mass violence that are uncoerced, largely intrinsically motivated, and committed for personal enjoyment.

The aim of the present study was to assess the effects of a lacto-ovo-vegetarian diet (VD), compared to a Mediterranean diet (MD), on kidney function in a group of subjects with medium-to-low cardiovascular risk profile.

We analysed 107 subjects (82 women, 25 men; median age 52) who followed a VD (n=54) and a MD (n=53) for 3months in the CARDIVEG study, a randomized, open, crossover trial that compared the effects of these 2 diets on cardiovascular disease risk.

The effect of the two diets on kidney function markers was evaluated by conducting a general linear model for repeated measurements adjusted for possible confounding factors such as age, sex, physical activity, alcohol, smoking, hypertension, LDL cholesterol, glucose and body weight change. A significant reduction in creatinine (-5.3%; P<.001), urea nitrogen levels (-9%; P=.001), blood urea nitrogen (BUN) (-8.7%; P=.001) and BUN/creatinine ratio (-5.8%; P<.001), and an increase in estimated glomerular filtration rate (eGFR) (+3.5%; P=.001) was observed during the VD period. On the contrary, no significant changes were noted in the MD group. Variations obtained in the two dietary interventions were significantly different (P<.0001) for creatinine levels, BUN/creatinine and eGFR, for which opposite trends were observed in the VD and MD groups.

In a selected group of subjects with medium-to-low cardiovascular risk profile, a 3month VD period determined significant improvements in kidney function markers. Further trials are needed to confirm these results.

Emergency department (ED) visits have declined while excess mortality, not attributable to COVID-19, has grown. It is not known whether older adults are accessing emergency care differently from their younger counterparts. Our objective was to determine patterns of ED visit counts for emergent conditions during the COVID-19 pandemic for older adults.

Retrospective, observational study.

Observational analysis of ED sites enrolled in a national clinical quality registry.

One hundred and sixty-four ED sites in 33 states from January 1, 2019 to November 15, 2020.

We measured daily ED visit counts for acute myocardial infarction (AMI), stroke, sepsis, fall, and hip fracture, as well as deaths in the ED, by age categories. We estimated Poisson regression models comparing early and post-early pandemic periods (defined by the Centers for Disease Control and Prevention) to the pre-pandemic period. We report incident rate ratios to summarize changes in visit incidence.

For AMI, stroke, and sepsis, the oldered and persistent than for younger patients, with fewer deaths in the ED. This is concerning given the greater prevalence and risk of poor outcomes for emergent conditions in this age group that are amenable to time-sensitive ED diagnosis and treatment, and may in part explain excess mortality during the COVID-19 era among older adults.The go/no-go successive matching-to-sample (S-MTS) procedure involves the presentation of a sample followed by one comparison in the same location. Participants are required to either touch (go) or refrain from touching (no-go) related and unrelated comparisons, respectively. One advantage of S-MTS is that both sample and comparisons can be auditory. Thus, the purpose of Experiment 1 was to establish three 3-member auditory equivalence classes using familiar dictated words. After training AB and AC relations, 16 out of 16 participants met emergence criterion for symmetry (BA/CA), 12 out of 16 for transitivity/equivalence (BC/CB), and 9 out of 16 for intraverbals, for which testing involved vocalizing relations among auditory stimuli. The purpose of Experiment 2 was to assess the potential influence of stimulus topography on equivalence class formation and the emergence of intraverbal behavior. After training AB and AC relations with unfamiliar stimuli, 16 out of 16 participants met emergence criterion for symmetry (BA/CA), 13 out of 16 for transitivity/equivalence (BC/CB), and 8 out of 16 for intraverbals. Results suggest that the S-MTS procedure may serve as an alternative to simultaneous MTS in the development of auditory equivalence classes.Why do some happenings become incentives for cultural or political transformation (that is turn into events), whereas others remain ordinary occurrences? The theoretical perspectives of cultural repertoires, cleavage structures, and discursive opportunities are prominent and fruitful approaches for explaining cultural or political behavior and attitudes, yet they do not have a satisfactory answer to this question. To fill in this gap, I introduce a typology that indicates how certain happenings merely reproduce existing trends, whereas other ones turn into motives to change them. This can be either because they are "focus events," which confirm dominant cultural or political patterns, or because they are "shock events," which form a break from them. I illustrate this typology by investigating the distinct meanings that 9/11 were accorded in the American and Dutch public spheres. This analysis shows that this happening became a "shock event" on the issue of safety in the American case, as it broke with the cultural repertoire of viewing the United States as a safe, militarily impenetrable nation. In contrast, 9/11 turned into a "focus event" concerning the issue of Islam in the Dutch case because it confirmed the discursive opportunities to problematize Muslims, which public actors in the Netherlands had already developed in the years leading up to 2001.

This cross-sectional study aimed to determine the prevalence and antimicrobial susceptibility of Gram-negative bacilli (GNB) isolated from subgingival biofilm of individuals with different periodontal conditions.

Subgingival biofilm was obtained from 362 individuals with periodontal health (PH) (n=83), gingivitis (n=74), and periodontitis (n=205), cultivated in broth and selective media. Isolated strains were identified by mass spectrometry. Antimicrobial susceptibility was determined by the Clinical and Laboratory Standards Institute disk diffusion guidelines. Production of extended-spectrum beta-lactamase (ESBL) and carbapenemases were evaluated by double disk synergy test and spectrophotometric detection of imipenem hydrolysis, respectively. ESBL and carbapenemase encoding genes were surveyed by Polymerase chain reaction (PCR). Differences among groups were examined by Chi-square, Kruskal-Wallis or Mann-Whitney tests.

GNB were isolated from 36.2% of all subgingival biofilm samples, with a significantly greater prevalence and species diversity (P<0.
