Knowledge of the evolutionary processes which govern pathogen recognition is critical to understanding durable disease resistance. We determined how Phytophthora infestans effector PiAVR2 is recognised by evolutionarily distinct resistance proteins R2 and Rpi-mcq1. We employed yeast two-hybrid, co-immunoprecipitation, virus-induced gene silencing, transient overexpression, and phosphatase activity assays to investigate the contributions of BSL phosphatases to R2- and Rpi-mcq1-mediated hypersensitive response (R2 HR and Rpi-mcq1 HR, respectively). Silencing PiAVR2 target BSL1 compromises R2 HR. Rpi-mcq1 HR is compromised only when BSL2 and BSL3 are silenced. BSL1 overexpression increases R2 HR and compromises Rpi-mcq1. However, overexpression of BSL2 or BSL3 enhances Rpi-mcq1 and compromises R2 HR. Okadaic acid, which inhibits BSL phosphatase activity, suppresses both recognition events. Moreover, expression of a BSL1 phosphatase-dead (PD) mutant suppresses R2 HR, whereas BSL2-PD and BSL3-PD mutants suppress Rpi-mcq1 HR. R2 interacts with BSL1 in the presence of PiAVR2, but not with BSL2 and BSL3, whereas no interactions were detected between Rpi-mcq1 and BSLs. Thus, BSL1 activity and association with R2 determine recognition of PiAVR2 by R2, whereas BSL2 and BSL3 mediate Rpi-mcq1 perception of PiAVR2. R2 and Rpi-mcq1 utilise distinct mechanisms to detect PiAVR2 based on association with different BSLs, highlighting central roles of these effector targets for both disease and disease resistance.

Nutrition status of very preterm infants in the neonatal intensive care unit (NICU) is strongly associated with postnatal growth. This study aimed to develop indicators of nutrition status using growth data of very preterm infants during hospitalization.

The data of 596 newborns from eight NICUs were retrospectively analyzed. Inclusion criteria were birth at <32 weeks’ gestation, NICU admission ≤24 h after delivery, and length of hospital stay ≥28 days. Three indicators were evaluated (indicator I) prevalence of extrauterine growth restriction (EUGR); (indicator II) z-score for change in weight from birth to discharge, adjusted for birth weight z-score and gestational age; and (indicator III) change in weight z-score from birth to discharge, adjusted for birth weight z-score, gestational age, and time to regain birth weight. Using data from NICU 1 as the reference for the latter two indicators, we established linear regression models of the adjusted change in weight z-score from birth to discharge. The difference between the observed value and the baseline value (calculated by the two models) served as the nutrition indices.

The prevalence of EUGR differed significantly between the eight NICUs (P = .009). Statistically significant differences were found between the mean indices calculated by the other two models (all P < .05).

Indicator III, change in weight z-score from birth to discharge (adjusted for birth weight z-score, gestational age, and time to regain birth weight), appears to be the most accurate for evaluating the quality of nutrition in the NICU.

In the United Kingdom, updated tables (the 8th edition) were published in July 2020. We have calculated impaired projected life expectancies for the United Kingdom based on age and gender, derived from the 8th edition of the Ogden Tables together with various assumed lifelong mortality ratios.Lutein and zeaxanthin (L/Z), xanthophylls obtained from the diet, are deposited in the macula of the eye. The macular concentration of L/Z is quantifiable as macular pigment optical density (MPOD). The aim of this review was to critically appraise the effect on MPOD of increasing L/Z intake by dietary intervention in adults. Pubmed, Cochrane Library, Web of Science, and Cinahl were searched up to April 2020. Ten studies investigating populations with and without age-related macular degeneration were included. MPOD increased significantly in 2 of the 8 controlled studies. Studies varied largely in the prescribed dietary L/Z dosage, duration, and participant characteristics. No relationships between types of dietary L/Z interventions and MPOD response could be determined. Limited monitoring of habitual dietary L/Z intake was identified as a major limitation of all 10 studies. Habitual dietary L/Z intake should be closely monitored in future studies to account for their effects on MPOD response to dietary L/Z interventions.

Three rounds of a repeated cross-sectional serosurvey to estimate the change in seroprevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were conducted from August to October 2020 in the state of Delhi, India, in the general population ≥5y of age.

The selection of participants was through a multistage sampling design from all 11 districts and 280 wards of the city-state, with multistage allocation proportional to population size. The blood samples were screened using immunoglobulin G (IgG) enzyme-linked immunosorbent assay kits.

We observed a total of 4267 (N=15046), 4311 (N=17409) and 3829 (N=15015) positive tests indicative of the presence of IgG antibody to SARS-CoV-2 during the August, September and October 2020 serosurvey rounds, respectively. The adjusted seroprevalence declined from 28.39% (95% confidence interval [CI] 27.65 to 29.14) in August to 24.08% (95% CI 23.43 to 24.74) in September and 24.71% (95% CI 24.01 to 25.42) in October. On adjusted analysis, participants with lower per capita income, living in slums or overcrowded households and those with diabetes comorbidity had significantly higher statistical odds of having antibody positivity (p<0.01).

Nearly one in four residents in Delhi, India ≥5y of age had the SARS-CoV-2 infection during August-October 2020.

Medicare beneficiaries are increasingly using home health as the first postacute care setting after hospital discharge following total joint arthroplasty (TJA). Yet, prior research has shown that changes in payment models for TJA may negatively influence functional outcomes for Medicare beneficiaries. The purpose of this study was to evaluate the impact of poor functional outcomes during a home health episode of care on hospitalization risk for older recipients of TJA.

For this study, 5822 Medicare beneficiaries who underwent elective TJA and subsequently participated in home health care following hospital discharge were identified using Medicare hospitalizations records and home health claims. Recovery of activities-of-daily-living (ADL) function was evaluated using patient assessment data completed at home health admission and discharge from the Medicare Outcomes and Assessment Information Set (OASIS). Hospitalization outcomes were captured from Medicare hospital claims. Cox-Proportional hazards regressring from interdisciplinary team members across the continuum of care, especially during transitions from home care to outpatient care.

An increasing number of patients receive home health care after joint replacement surgery, but outcomes after home health are unclear. These findings suggest that improvements in basic tasks such as walking or bathing are associated with a lower likelihood of hospitalization.

As both mortality ratios and excess death rates are widely used in medical and legal settings, it is hoped that these additional tables of life expectancies will be of practical value.

Prevalence of overweight and obesity has been rising in the past 3 decades among Mexican children and adolescents.

To systematically review experimental studies evaluating interventions to treat obesity in Mexican children and adolescents (≤18 years old).

For this study, 13 databases and 1 search engine were searched.

A total of 29 studies met the inclusion criteria. Overall, 2302 participants (age range, 8-16 years) from 11 states in Mexico were included. Most of the studies (n = 17 of 29) were provided in a clinical setting. A random-effect meta-analysis of 4 randomized controlled trials was conducted and a significant effect was found on body mass index reduction that favored the intervention group (-1.52; 95%CI, -2.15 to -0.89) for short-term (≤6 mo) interventions.

A multicomponent, multidisciplinary, and individualized intervention that includes dietary modifications, physical activity practice, behavioral strategies, and active parental involvement might help treat childhood obesity in Mexico. However, long-term results need to be produced to identify effectiveness pointers that might help establish an integrated, long-lasting care model to treat obesity.

The Mini-BESTest is a balance scale common to clinical practice, but different scoring has been proposed, that is, total score and/or subsections. This study aimed to investigate Mini-BESTest validity by comparing 6 structural models and to establish the best model for discriminating fallers from nonfallers, ie, those who did or did not report at least two falls in the six months before evaluation.

In this cross-sectional validation study, data from 709 individuals with idiopathic Parkinson disease (Hoehn and Yahr stages 1-3) were analyzed. Individuals were evaluated with the Mini-BESTest, and fall history was recorded. Construct, convergent, and discriminant validity and reliability of the 6 models were analyzed. The ability of the models to adequately identify individuals with or without a history of falls was tested with receiving operating characteristic curves.

Confirmatory factor analysis showed that the unidimensional models and the 4-factor solutions showed the best fit indexes. Conversely, second-order models, which allowed reporting of both total and subsections, did not converge.
