ABSTRACT Ceftazidime-avibactam is a potent antibiotic combination against Klebsiella pneumoniae carbapenemase (KPC)-producing Enterobacteriaceae. Here, we describe a unique ceftazidime-avibactam-resistant and carbapenem-susceptible K. pneumoniae strain harboring a novel blaKPC-14 variant. This strain was isolated from a New York City patient in 2003, which predates the introduction of avibactam. Despite resistance to ceftazidime-avibactam, the strain was susceptible to imipenem-relebactam and meropenem-vaborbactam. Comprehensive genomic sequencing revealed that blaKPC-14 is harbored on an ST6 IncN plasmid associated with the early spread of blaKPC. IMPORTANCE KPC is currently the most common carbapenemase identified in the United States. More than 40 KPC variants have been described, of which KPC-2 and KPC-3 are the most frequent clinical variants. However, our understanding of the genetic structures and β-lactam resistance profiles of other novel KPC variants remains incomplete. Here, we report a novel blaKPC variant (blaKPC-14) and the complete genome sequence of blaKPC-14-harboring K. pneumoniae strain BK13048, which is susceptible to carbapenems but resistant to ceftazidime-avibactam. To the best of our knowledge, this is one of the earliest KPC-producing K. pneumoniae strains exhibiting resistance to ceftazidime-avibactam.

Abstract The spread of mcr-1 in the United States remains poorly defined. mcr-1-producing Escherichia coli that also carried blaSHV-12 was detected in a hospitalized patient. No additional cases were identified during screening of 801 Gram-negative isolates. Genomic sequencing identified an IncX4 mcr-1- harboring plasmid and ST117 clonal background associated with avian pathogenic E coli.

Despite the growing importance of carbapenem-resistantKlebsiella pneumoniae(CRKP), the clonal relationships between CRKP and antibiotic-susceptible isolates remain unclear. We compared the genetic diversity and clinical features of CRKP, third-generation and/or fourth-generation cephalosporin-resistant (Ceph-R)K. pneumoniae, and susceptibleK. pneumoniaeisolates causing bloodstream infections at a tertiary care hospital in New York City between January 2012 and July 2013. Drug susceptibilities were determined with the Vitek 2 system. Isolates underwent multilocus sequence typing and PCR sequencing of thewziandblaKPCgenes. Clinical and microbiological data were extracted from patient records and correlated with molecular data. Among 223 patients, we identified 272 isolates. Of these, 194 were susceptible, 30 Ceph-R, and 48 CRKP, belonging to 144 sequence types (STs). Susceptible (127 STs) and Ceph-R (20 STs) isolates were highly diverse. ST258 dominated CRKP strains (12 STs, with 63% ST258). There was minimal overlap in STs between resistance groups. TheblaKPC-3gene (30%) was restricted to ST258/wzi154, whereasblaKPC-2(70%) was observed for severalwziallele types. CRKP infections occurred more frequently among solid organ transplant (31%) and dialysis (17%) patients. Mortality rates were high overall (28%) and highest among CRKP-infected patients (59%). In multivariable analyses, advanced age, comorbidities, and disease severity were significant predictors of 30-day mortality rates, whereas theK. pneumoniaesusceptibility phenotype was not. Among CRKP infections, we observed a borderline significant association of increased mortality rates with ST258 and thewzi154 allele. Although the clonal spread of ST258 continues to contribute substantially to the dissemination of CRKP, non-ST258 strains appear to be evolving. Further investigations into the mechanisms promoting CRKP diversification and the effects of clonal backgrounds on outcomes are warranted.

ABSTRACT Carbapenem-resistant Klebsiella strains carrying Klebsiella pneumoniae carbapenemases (KPC) are endemic to New York City and are spreading across the United States and internationally. Recent studies have indicated that the KPC structural gene is located on a 10-kb plasmid-borne element designated Tn4401. Fourteen Klebsiella pneumoniae strains and one Klebsiella oxytoca strain isolated at a New York City hospital in 2005 carrying either bla KPC-2 or bla KPC-3 were examined for isoforms of Tn4401. Ten of the Klebsiella strains contained a 100-bp deletion in Tn4401, corresponding to the Tn4401a isoform. The presence of this deletion adjacent to the upstream promoter region of bla KPC in Tn4401a resulted in a different −35 promoter sequence of TGGAGA than that of CTGATT present in isoform Tn4401b. Complete sequencing of one plasmid carrying bla KPC from each of three nonclonal isolates indicated the presence of genes encoding other types of antibiotic resistance determinants. The 70.6-kb plasmid from K. pneumoniae strain S9 carrying bla KPC-2 revealed two identical copies of Tn4401b inserted in an inverse fashion, but in this case, one of the elements disrupted a group II self-splicing intron. In K. pneumoniae strain S15, the Tn4401a element carrying bla KPC-2 was found on both a large 120-kb plasmid and a smaller 24-kb plasmid. Pulsed-field gel electrophoresis results indicate that the isolates studied represent a heterogeneous group composed of unrelated as well as closely related Klebsiella strains. Our results suggest that endemic KPC-positive Klebsiella strains constitute a generally nonclonal population comprised of various alleles of bla KPC on several distinct plasmid genetic backgrounds. This study increases our understanding of the genetic composition of the evolving and expanding role of KPC-producing, healthcare-associated, gram-negative pathogens.

ABSTRACTImipenem with relebactam was active againstEscherichia coli,Klebsiella pneumoniae, andEnterobacterspp., includingK. pneumoniaecarbapenemase (KPC)-producing isolates. Loss of OmpK36 in KPC-producingK. pneumoniaeisolates affected the susceptibility of this combination. Enhanced activity was evident againstPseudomonas aeruginosa, including isolates with depressedoprDand increasedampCexpression. However, the addition of relebactam to imipenem did not provide added benefit againstAcinetobacter baumannii. The combination of imipenem with relebactam demonstrated activity against KPC-producingEnterobacteriaceaeand multidrug-resistantP. aeruginosa.

Forty-eight hours after they landed in New York City in 1880, a small contingent of the Salvation Army held their first public meeting at the infamous Harry Hill's Variety Theater. The enterprising Hill, alerted to the group's arrival from Britain by newspaper reports, contacted their leader, Commissioner George Scott Railton, and offered to pay the group to “do a turn” for “an hour or two on … Sunday evening.” In nineteenth-century New York City, Harry Hill's was one of the best known concert saloons, and reformers considered him “among the disreputable classes” of that city. His saloon, they said, was “nothing more than one of the many gates to hell.”

This paper describes the relation between values and behavior of a new life style, that of voluntary simplicity which is characterized by low consumption, self-sufficiency, and ecological responsibility. Also, specific hypotheses regarding the motivation for voluntary simplicity and adoption in two areas of the United States were tested. Analysis shows (a) values of voluntary simplicity and behaviors are consistent, (b) the motivation for voluntary simplicity includes personal preference and economic hardship, and (c) adoption of voluntary simplicity is different in the Denver and New York City metropolitan areas.

Abstract Background There has been increasing recognition that certain vulnerable populations in the United States of America struggle to meet their menstruation-related needs, including people experiencing homelessness. Media and policy attention on this subject has focused on the provision of free menstrual products to vulnerable populations, including a New York City legislative bill, which guarantees access to menstrual products for Department of Homeless Services shelter residents (Intros 1123-A). Methods This qualitative study explored the challenges people experiencing homelessness in New York City face in accessing menstrual products. Data collection was conducted from June to August 2019 and included: Semi-structured key informant interviews with staff from relevant government agencies and homeless service providers (n = 15), and semi-structured in-depth interviews with individuals with experience living on the street and in shelters (n = 22). Data were analysed using thematic analysis. Results Key themes that emerged included: (1) insufficient and inconsistent access to menstrual products; (2) systemic challenges to providing menstrual products; and (3) creative solutions to promote access to menstrual products. Both shelter- and street-living individuals reported significant barriers to accessing menstrual products. While both populations struggle, those in shelters were more likely to be able to purchase menstrual products or access free products at their shelter, while those living on the streets were more likely to have to resort to panhandling, theft, or using makeshift materials in place of menstrual products. Across both populations, individuals described barriers to accessing free products at shelters and service providers, primarily due to distribution systems that rely on gatekeepers to provide a few pads or tampons at a time, sometimes of inadequate quality and only upon request. Shelters and service providers also described challenges providing these products, including inconsistent supply. Conclusion These findings highlight the critical importance of expanding and improving initiatives seeking to provide access to menstrual products for vulnerable populations. Despite policy level efforts to support menstrual product access, individuals experiencing homelessness in New York City, whether living in shelters or on the street, are often not able to access the menstrual products that they need to manage their monthly menstrual flow.

This article reports on the first 2 years of an ongoing project that examined the efficacy of a 10-hour dementia training provided to entry-level personal care aide (PCA) trainees from the Hispanic, White, African American, and Asian communities in New York City. Participants were enrolled in a 90-hour PCA training program offered by the New York City Department for the Aging and were either recipients of public assistance, displaced employees from September 11, or recent immigrants to the United States from China. Classes were conducted in Spanish, English, and Mandarin/Cantonese. An 11-item Knowledge of Alzheimer’s Disease instrument was developed for the purposes of this project and administered before and after the dementia training and at 3 months following graduation. All groups, regardless of language, showed a significant increase in knowledge of Alzheimer’s disease at the conclusion of the training and retention of this knowledge at 3 months follow-up. Age was strongly correlated with an increase in knowledge, while gender and education were not.

Objectives Immigrant adults tend to have better health than native-born adults despite lower incomes, but the health advantage decreases with length of residence. To determine whether immigrant adults have a health advantage over US-born adults in New York City, we compared cardiovascular disease (CVD) risk factors among both groups. Methods Using data from the New York City Health and Nutrition Examination Survey 2013-2014, we assessed health insurance coverage, health behaviors, and health conditions, comparing adults ages ≥20 born in the 50 states or the District of Columbia (US-born) with adults born in a US territory or outside the United States (immigrants, following the National Health and Nutrition Examination Survey) and comparing US-born adults with (1) adults who immigrated recently (≤10 years) and (2) adults who immigrated earlier (>10 years). Results For immigrant adults, the mean time since arrival in the United States was 21.8 years. Immigrant adults were significantly more likely than US-born adults to lack health insurance (22% vs 12%), report fair or poor health (26% vs 17%), have hypertension (30% vs 23%), and have diabetes (20% vs 11%) but significantly less likely to smoke (18% vs 27%) (all P < .05). Comparable proportions of immigrant adults and US-born adults were overweight or obese (67% vs 63%) and reported CVD (both 7%). Immigrant adults who arrived recently were less likely than immigrant adults who arrived earlier to have diabetes or high cholesterol but did not differ overall from US-born adults. Conclusions Our findings may help guide prevention programs and policy efforts to ensure that immigrant adults remain healthy.
