 The estimated seroprevalence of 23% was three-fold higher than the number of cases reported in the COVID-19 Integrated Surveillance data in the study area. This may be explained in part by a relatively high number of individuals presenting mild or no illness, especially those of younger age, and people who did not seek medical care or testing, but who may contribute to virus transmission in the community.
  To evaluate the accuracy and reproducibility of antimicrobial susceptibility testing methods in Burkholderia cepacia complex (BCC).
 
  Minocycline, ciprofloxacin, trimethoprim/sulphamethoxazole, meropenem, ceftazidime and chloramphenicol were tested against 155 BCC strains using broth microdilution at 35±1°C (BMD
  ) in triplicate, then BMD at 30±1°C (BMD
  ), agar dilution at 30°C and 35°C (AD
  and AD
  ), gradient strip (GS) and EUCAST standardized disc diffusion (DD) testing methods once.
 
  BMD
  reproducibility ranged from 70% to 84.5% for all agents. Correlations of MICs from BMD
  with BMD
  ranged from 63% to 85%, with AD
  from 32.9% to 87% and with GS methods from 36% to 83.9%. Essential agreement (EA) of MICs by GS with BMD
  ranged from 62.6% (trimethoprim-sulphamethoxazole) to 83.9% (minocycline). EA of EUCAST DD zone diameters using CLSI breakpoint criteria was between 85.8% and 97.4%, however Very Major Errors (VME) for trimethoprim/sulphamethoxazole were 31%.
 
  BMD at 35±1°C was poorly reproducible for most agents and no method showed acceptable performance. Of particular concern were the GS results. Although this is the most commonly used method for determining MICs in laboratories, there was poor correlation with BMD
  for meropenem and trimethoprim/sulphamethoxazole. EUCAST DD correlated poorly with BMD
  MICs. This study confirms that no susceptibility method is capable of providing reproducible and accurate MICs when testing BCC.
 BMD at 35 ± 1°C was poorly reproducible for most agents and no method showed acceptable performance. Of particular concern were the GS results. Although this is the most commonly used method for determining MICs in laboratories, there was poor correlation with BMD35 for meropenem and trimethoprim/sulphamethoxazole. EUCAST DD correlated poorly with BMD35 MICs. This study confirms that no susceptibility method is capable of providing reproducible and accurate MICs when testing BCC.In 2012, swine influenza surveillance detected a novel reassorted influenza A virus (IAV) strain containing human-seasonal hemagglutinin (HA) and neuraminidase (NA). Subsequently, these viruses reassorted, maintaining only the human-origin H3, which resulted in a new lineage of viruses that became the most frequently detected H3 clade in US swine (2010.1 HA clade). Here, we assessed the antigenic phenotype, virulence, and transmission characteristics of this virus lineage following its introduction to swine. Relative to 2010.1 viruses from 2012 and 2014, recent 2010.1 contemporary strains from 2015 to 2017 resulted in equivalent macroscopic lung lesions and transmission in pigs. A single mutation at amino acid residue 145 within the previously defined HA antigenic motif was associated with a change of antigenic phenotype, potentially impairing vaccine efficacy. Contemporary 2010.1 viruses circulating in swine since 2012 were significantly different from both pre-2012H3N2 in swine and human-seasonal H3N2 viruses and demonstrated continued evolution within the lineage.
  Despite increased routine screening for food insecurity (FI) in pediatric medical settings, the uptake of offered food resources after FI identification is not well understood. We aimed to 1) describe utilization of referral and supplemental resources and 2) identify characteristics associated with utilization.
 
  We linked hospital screening and Electronic Medical Record data to Hunger Free Colorado (HFC) referral data for patients 0 to 18 years who were screened in the emergency department (ED), inpatient, or outpatient setting from January 2017 to December 2018. Among FI families, we compared patient demographic and clinical variables based on acceptance of HFC referral and connection to a food resource using Pearson's chi-square, Wilcoxon rank sum, and Poisson regression.
 
  Of 1952 patients with FI, 371 (19%) accepted a referral to HFC and of these 228 (61%) were connected to a food resource. In adjusted analyses, families screened in the ED (adjusted relative risks [aRR] 1.96, confidence interval [CI] 1.57-2.44) and inpatient (aRR 1.74, CI 1.20-2.53) settings more often pursued referral to HFC than those screened in Child Health Clinic, while those screened in Special Care Clinic less often pursued referral (aRR 0.24, CI 0.14-0.41). Families with 3 or more people in the home were more likely to be connected to resources (aRR 2.67, CI 1.42-5.04).
 
  Only a small proportion of families with FI identified in a medical setting are ultimately connected to food resources. Higher rates of HFC referral among ED and inpatient families suggest that increased screening efforts in these settings may be warranted.

  Childhood food insecurity endangers child development and health outcomes.  https://www.selleckchem.com/products/amg510.html  Food insecurity will grow increasingly common in the economic wake of the coronavirus pandemic and prenatal care represents an early, clinical opportunity to identify families at risk. However, longitudinal relationships between clinically-identified prenatal food insecurity and prematurity, pediatric health care utilization, and postnatal social needs have not been described.
 
  We examined longitudinal data from mother-child dyads who received prenatal and pediatric care and social needs screening at a large academically-affiliated safety net medical center between October 2018 and July 2019. Associations among household food insecurity and premature birth, pediatric inpatient and outpatient utilization, missed immunizations, and postnatal social needs were estimated using adjusted regression.
 
  Among the 268 mothers, those who experienced prenatal household food insecurity had 3 times higher odds of having a child born prematurely (95% confidence interval [CI] 1.
