Early clinical results of a new total knee arthroplasty (TKA) implant design show promise for improved outcomes and patellofemoral function scores. However, reports of early tibial component-cement interface debonding requiring revision have been published. This study investigated the biomechanical properties of three different tibial baseplates to understand potential causes of failure.

PFC Sigma (control), Attune (1st generation) and Attune S+ (2nd generation) tibial baseplates were implanted into 4th generation sawbone tibia models using a standardized technique. Three of each baseplate were cemented with and without additional bovine bone marrow fat. All models were tested to failure with measured axial distraction force. Implant type, presence or absence of bovine marrow and load to failure were all recorded and compared. Two-way ANOVA followed by post-hoc pairwise comparisons were used to determine statistical significance, which was set to P < .05.

The 2nd generation tibial baseplates required the cement-implant interface.

The concept of sepsis has recently been redefined by an International Task Force. The task force recommended the use of the quick Sequential Organ Failure Assessment (qSOFA) score instead of Systemic Inflammatory Response Syndrome (SIRS) criteria to identify patients at high risk of mortality from sepsis outside of the intensive care unit, including in emergency departments (EDs). However, the primary outcome for qSOFA is prediction of risk for mortality, which is not the principal outcome measure considered in the ED. From the ED perspective, the priorities are the identification (diagnosis) of the septic patient and then the initiation of time-sensitive, life-saving interventions.

We performed a structured review of PubMed from January 2012 to December 2018, limited to reports involving human subjects and written in English language and containing relevant keywords. The highest-quality studies were then reviewed in a structured format. We utilized these studies to estimate the sensitivity and specificity of SIRS and qSOFA for diagnosis of sepsis.

Thirteen unique articles were identified for further review, and the 11 highest-grade articles (C and D) were determined to be appropriate for inclusion in this review, and the two low-grade articles were excluded (E).

Based on multiple retrospective and few prospective studies, it appears that qSOFA performs poorly in comparison with SIRS as a diagnostic tool for ED patients who may have sepsis or septic shock. However, qSOFA does have a strong prognostic accuracy for mortality in those ED patients already diagnosed with sepsis or septic shock.

This study examines COVID-19-associated discrimination regardless of infection status. It evaluates the contribution of various risk factors (e.g., race/ethnicity and wearing a face mask) and the relationship with mental distress among U.S. adults in March and April 2020, when the pandemic escalated across the country.

Participants consisted of a probability-based, nationally representative sample of U.S. residents aged ≥18 years who completed COVID-19-related surveys online in March and April (n=3,665). Multivariable logistic regression was used to predict the probability of a person perceiving COVID-19-associated discrimination. Linear regression was used to analyze the association between discrimination and mental distress. Analyses were conducted in May 2020.

Perception of COVID-19-associated discrimination increased from March (4%) to April (10%). Non-Hispanic Black (absolute risk from 0.09 to 0.15 across months) and Asians (absolute risk from 0.11 to 0.17) were more likely to perceive discriminatif this novel form of discrimination should be monitored.This paper explores the interaction between peer relationships and sexual health among street youth in three Sub-Saharan African cities Accra (Ghana), Bukavu (Democratic Republic of Congo), and Harare (Zimbabwe). It begins by conceptualising peer relationships for youth globally and considers why these are pivotal for young people living in street settings. The paper reconceptualizes street peer relationships not as replacement families, but as sharing 'social anchorage' in the street space. It draws on qualitative ethnographic data from Growing up on the Streets, a longitudinal research project with a participatory methodology undertaken between 2012 and 2016 and engaging street youth (aged 14-20 at project outset) trained in ethnographic observations as research assistants (n = 18), following a network of ten peers (n = 229 by 2016), reporting their experiences in weekly interviews with facilitators. A wider network attended focus groups (n = 399). The project engaged a 'capability' approach, with ten capab health has become even more relevant in a (post)pandemic world.In this study, we examined the potential association of telomere length with Parkinson's disease (PD) using the publicly available genome-wide association study summary statistics from the International Parkinson's Disease Genomics Consortium involving up to 37,688 patients with PD and 449,056 controls in Mendelian randomization framework. The Mendelian randomization approach has the potential to investigate a causal relationship between a risk factor and a disease, avoiding confounding and reverse causation that often present in conventional epidemiological studies. We did not find that longer telomeres were associated with higher risks of PD (odds ratio 1.18, 95% confidence interval 0.94, 1.48, p = 0.15). Our study, therefore, did not provide evidence to support a potential causal relationship between telomere length and PD.

There are many studies of women's experiences of care during the postnatal period, however little is known about women's expectations of postnatal care.

This study explores first-time pregnant women's expectations, both ideal and real life, of postnatal care in England.

a descriptive, cross-sectional online survey design was used. MF438 The questionnaire took approximately 10 minutes to complete and was developed specifically for this survey. It included an informed consent section, socio-demographic questions and closed tick-box questions on where they had received information on postnatal care, and real and ideal expectations of postnatal care in hospital/birth centre and at home.

The survey was hosted on the National Perinatal Epidemiology Unit website and advertised through a number of third sector and commercial organisations in 2017.

Women who were pregnant, had not given birth before, were aged 16 years and over, and living in England were eligible to participate.

Survey data were analysed using descriptive statistics and, where appropriate, chi square test using SPSS Version 23.
