#1
L A Pereira, A F B Abreu, I C Vieira Júnior, L P M Pires, M A P Ramalho
Common bean producers in Brazil tend to grow plants as upright as possible. Because the control of this trait involves a large number of genes, recurrent selection (RS) is the best approach for successful plant improvement. Because plant architecture (PA) is evaluated using scores and usually has high heritability, RS for PA is performed through visual selection in generation S0. The aim of the present study was to evaluate selection progress and investigate whether this progress varies with the number of selected progenies or the generation evaluated...

Injuries to the central slip of the extensor mechanism can lead to a Boutonniere deformity with important functional consequences. We report a series of 11 patients treated by lengthening-dorsalizing the lateral bands and tightening the central slip with early mobilization. The average age of the patients was 42 years (14;52). The extension defect of the proximal interphalangeal (PIP) joint was 64 degrees (80;55) and the hyperextension of the distal interphalangeal joint was 10 degrees (15;5). The surgery was performed with peripheral nerve block (sensitive), allowing dynamic adjustment of the tendinous sutures...

OBJECTIVE: Positive associations between radiographic osteoarthritis (OA) and areal BMD have been demonstrated and appear strongest when bony features of OA are considered. To date, these associations have not been assessed using HRpQCT. DESIGN: A total of 318 participants (170 men and 148 women), aged 72.1-81.4 years from a non-selected cohort, underwent HRpQCT of the distal radius and tibia along with hip radiography. Differences in bone microarchitecture were assessed between those with and without osteophytes, sclerosis or joint space narrowing (JSN) in either hip...

BACKGROUND: Periprosthetic joint infection (PJI) after total joint arthroplasty (TJA) is a serious complication with multiple etiologies. Prior spine literature has shown that later cases in the day were more likely to develop surgical site infection. However, the effect of case order on PJI after TJA is unknown. This study aims to determine the influence of case order, prior infected case, and terminal cleaning on the risk for a subsequent PJI. METHODS: A retrospective, single-institution study was conducted on 31,499 TJAs performed from 2000 to 2014...

OBJECTIVE: Increasing evidence has suggested a protective role of vitamin D on metabolic syndrome (MetS). However, studies addressing this issue are limited in Asia and it remains unclear whether calcium could modify the association. We examined the association of serum 25-hydroxyvitamin D (25(OH)D) status with MetS, and the potential effect modification by calcium intake in a Japanese working population. METHODS: Study subjects were 1790 workers, ages 18 to 69 y, who participated in a health survey at the time of periodic checkup...

The incidence of Staphylococcus aureus bacteremia (SAB) is significantly higher in African American (AA) than in European-descended populations. We used admixture mapping (AM) to test the hypothesis that genomic variations with different frequencies in European and African ancestral genomes influence susceptibility to SAB in AAs. A total of 565 adult AAs (390 cases with SAB; 175 age-matched controls) were genotyped for AM analysis. A case-only admixture score and a mixed χ(2)(1df) score (MIX) to jointly evaluate both single-nucleotide polymorphism (SNP) and admixture association (P<5...

A refined exposure assessment was undertaken to calculate the Estimated Daily Intake (EDI) of the seven FD&C straight colour additives and five FD&C colour lakes ("synthetic" food colours) approved in the United States (US). The EDIs were calculated for the US population as a whole and specific age groups, including children 2-5 y, children 6-12 y, adolescents 13-18 y, and adults 19+ y. Actual use data were collected from an industry survey of companies who are users of these colour additives in a variety of products, with additional input from food colour manufacturers...

Context: Physical activity (PA) is associated with 25-hydroxyvitamin D [25(OH)D] levels. Both are associated with atherosclerotic cardiovascular disease (ASCVD), but their joint association with ASCVD risk is unknown. Objective: To examine the dose-response between PA and 25(OH)D, and to assess effect modification of 25(OH)D and PA with ASCVD risk. Design: Cross-sectional and prospective study using Poisson and linear regression. Setting: Community-dwelling Atherosclerosis Risk in Communities cohort...

This study aimed to determine the extent to which changes over 2.5 years in medial knee cartilage thickness and volume were predicted by: (1) peak values of the knee adduction (KAM) and flexion moments; and (2) KAM impulse and loading frequency, representing cumulative load, after controlling for age, sex and body mass index (BMI). Adults with clinical knee osteoarthritis participated. At baseline and approximately 2.5 years follow-up, cartilage thickness and volume of the medial tibia and femur were segmented from magnetic resonance imaging scans...

Importance: In the United States, hospitals receive accreditation through unannounced on-site inspections (ie, surveys) by The Joint Commission (TJC), which are high-pressure periods to demonstrate compliance with best practices. No research has addressed whether the potential changes in behavior and heightened vigilance during a TJC survey are associated with changes in patient outcomes. Objective: To assess whether heightened vigilance during survey weeks is associated with improved patient outcomes compared with nonsurvey weeks, particularly in major teaching hospitals...

Tremendous pathologic diversity among sinonasal and ventral skull base malignancies complicates development of a uniform and prognostically relevant staging system. Because of the comparatively low incidence of these tumors, comprehensive evaluation and comparison of specific staging systems is difficult. The current American Joint Committee on Cancer TNM staging system for sinonasal malignancies is the most common and widely used system in current clinical practice. Alternative systems have been proposed for use with individual histopathologic subtypes...

BACKGROUND: Total knee arthroplasty (TKA), aiming at neutral mechanical alignment (MA), inevitably modifies the patient's native knee anatomy. Another option is kinematic alignment (KA), which aims to restore the original anatomy of the knee. The aim of this study was to evaluate the variations in lower limb anatomy of a patient population scheduled for TKA, and to assess the use of a restricted KA TKA protocol and compare the resulting anatomic modifications with the standard MA technique...

Fan Jiang, Hao Wu, Haizhen Yue, Fei Jia, Yibao Zhang
The enhanced dosimetric performance of knowledge-based volumetric modulated arc therapy (VMAT) planning might be jointly contributed by the patient-specific optimization objectives, as estimated by the RapidPlan model, and by the potentially improved Photon Optimizer (PO) algorithm than the previous Progressive Resolution Optimizer (PRO) engine. As PO is mandatory for RapidPlan estimation but optional for conventional manual planning, appreciating the two optimizers may provide practical guidelines for the algorithm selection because knowledge-based planning may not replace the current method completely in a short run...

While adverse childhood experiences have been shown to contribute to adverse health outcomes in adulthood, specifically distress and somatic symptoms, few studies have examined their joint effects with resilient coping style on adult adjustment. Hence, we aim to determine the association between resilient coping and distress in participants with and without reported childhood adversities. A representative German community sample (N = 2508) between 14-92 years (1334 women; 1174 men) was examined by the short form of the Childhood Trauma Questionnaire, the Brief Resilience Coping Scale, standardized scales of distress and somatoform symptoms...

BACKGROUND: Studies of obesity and survival among patients with breast cancer produce conflicting results, possibly because of heterogeneity by molecular subtype. METHODS: This study examined whether the association of body mass index (BMI) at diagnosis with breast cancer recurrence and survival varied across subtypes defined by PAM50 (Prediction Analysis of Microarray 50) gene expression. Included were 1559 Kaiser Permanente Northern California members ages 18 to 79 years who had PAM50 assays and were diagnosed with American Joint Committee on Cancer stage I through III breast cancer from 1996 to 2013...

BACKGROUND: Diabetes, hyperglycemia, and their complications are a growing problem in Brazil. However, no comprehensive picture of this disease burden has yet been presented to date. METHODS: We used Global Burden of Disease 2015 data to characterize diabetes prevalence, incidence and risk factors from 1990 to 2015 in Brazil. Additionally, we provide mortality, years of life lost prematurely (YLL), years of life lived with disability (YLD) and disability-adjusted life years (DALYs) lost due to diabetes, as well as similar data for chronic kidney disease (CKD) due to diabetes and, as an overall summary measure, for hyperglycemia, the latter expressed as high fasting plasma glucose (HFPG)...
