Abstract Background Respiratory diphtheria is a toxin-mediated disease caused by Corynebacterium diphtheriae. Diphtheria-like illness, clinically indistinguishable from diphtheria, is caused by Corynebacterium ulcerans, a zoonotic bacterium that can also produce diphtheria toxin. In the United States, respiratory diphtheria is nationally notifiable: specimens from suspected cases are submitted to the Centers for Disease Control and Prevention (CDC) for species and toxin confirmation, and diphtheria antitoxin (DAT) is obtained from CDC for treatment. We summarize the epidemiology of respiratory diphtheria and diphtheria-like illness and describe DAT use during 1996–2018 in the United States. Methods We described respiratory diphtheria cases reported to the National Notifiable Diseases Surveillance System (NNDSS) and C. ulcerans-related diphtheria-like illness identified through specimen submissions to CDC during 1996–2018. We reviewed DAT requests from 1997 to 2018. Results From 1996 to 2018, 14 respiratory diphtheria cases were reported to NNDSS. Among these 14 cases, 1 was toxigenic and 3 were nontoxigenic C. diphtheriae by culture and Elek, 6 were culture-negative but polymerase chain reaction (PCR)-positive for diphtheria toxin gene, 1 was culture-positive without further testing, and the remaining 3 were either not tested or tested negative. Five cases of respiratory diphtheria-like illness caused by toxigenic C. ulcerans were identified. DAT was requested by healthcare providers for 151 suspected diphtheria cases between 1997 and 2018, with an average of 11 requests per year from 1997 to 2007, and 3 per year from 2008 to 2018. Conclusions Respiratory diphtheria remains rare in the United States, and requests for DAT have declined. Incidental identification of C. ulcerans-related diphtheria-like illness suggests surveillance of this condition might be warranted.

Abstract Background Influenza causes significant morbidity and mortality and stresses hospital resources during periods of increased circulation. We evaluated the effectiveness of the 2019-2020 influenza vaccine against influenza-associated hospitalizations in the United States. Methods We included adults hospitalized with acute respiratory illness at 14 hospitals and tested for influenza viruses by reserve transcription polymerase chain reaction. Vaccine effectiveness (VE) was estimated by comparing the odds of current-season influenza vaccination in test-positive influenza cases versus test-negative controls, adjusting for confounders. VE was stratified by age and major circulating influenza types along with A(H1N1)pdm09 genetic subgroups. Results 3116 participants were included, including 18% (553) influenza-positive cases. Median age was 63 years. Sixty-seven percent (2079) received vaccination. Overall adjusted VE against influenza viruses was 41% (95% confidence interval [CI]: 27-52). VE against A(H1N1)pdm09 viruses was 40% (95% CI: 24-53) and 33% against B viruses (95% CI: 0-56). Of the two major A(H1N1)pdm09 subgroups (representing 90% of sequenced H1N1 viruses), VE against one group (5A+187A,189E) was 59% (95% CI: 34-75) whereas no significant VE was observed against the other group (5A+156K) [-1%, 95% CI: -61-37]. Conclusions In a primarily older population, influenza vaccination was associated with a 41% reduction in risk of hospitalized influenza illness.

Exposure Prophylaxis

Pre-Exposure Prophylaxis (PrEP) has been shown to be an effective method of HIV prevention for men who have sex with-men (MSM) and -transgender women (MSTGWs), serodiscordant couples, and injection drug users; however fewer than 50 000 individuals currently take this regimen. Knowledge of PrEP is low among healthcare providers and much of this lack of knowledge stems from the lack or exposure to PrEP in medical school. We conducted a cross sectional survey of medical schools in the United States to assess the degree to which PrEP for HIV prevention is taught. The survey consisted Likert scale questions assessing how well the students were prepared to perform each skill associated with PrEP delivery, as well as how PrEP education was delivered to students. We contacted 141 medical schools and 71 responded to the survey (50.4%). PrEP education was only reported to be offered at 38% of schools, and only 15.4% reported specific training for Lesbian, Gay, Bisexual, and Transgender (LGBT) patients. The most common delivery methods of PrEP content were didactic sessions with 11 schools reporting this method followed by problem-based learning, direct patient contact, workshops, and small group discussions. Students were more prepared to provide PrEP to MSM compared to other high-risk patients. Few medical schools are preparing their students to prescribe PrEP upon graduation. Further, there is a need to increase the number of direct patient contacts or simulations for students to be better prepared.

Background: An estimated 95% of all online pharmacies operate unlawfully. Illegal online pharmacies distribute substandard and falsified medical products that may result in patient harm and suboptimal treatment, leading to an overall mistrust of medications, healthcare providers, and health systems. As medication experts, pharmacists are trusted to guide patients in selection of safe and effective medication therapy. Objective: The objective of this study was to determine gaps in knowledge and recognition of the negative clinical and safety impacts associated with illegal Internet pharmacies by licensed pharmacists. Methods: A 37-question electronic survey was developed and distributed to pharmacists across the United States by email via a database from the American Pharmacists Association. Descriptive statistics was utilized to analyze data. Results: A total of 347 pharmacists from across the United States responded to at least one question in the survey. In all, 58% of pharmacists reported a lack of confidence in their ability to counsel patients on the identification of illegal pharmacy websites. Fewer than 60% of pharmacists were able to accurately identify the legitimacy of a webpage based on visual characteristics. In addition, 75% of pharmacists reported being unfamiliar with resources available to help consumers identify safe and legitimate online pharmacies. Conclusion: Integration of the topic into pharmacy education curricula, training on available resources, and additional research into the prevalence and impact of illegal pharmacy websites are necessary to ensure that pharmacists and other healthcare professionals are adequately prepared to protect their communities from the threat of illegal online pharmacies.

Year 2000

The incidence of HIV infection and AIDS in children has grown at an alarming rate. Approximately one million children worldwide have HIV infection. By the year 2000, an estimated ten million children will suffer from the disease. Currently, the United States has a population of an estimated 10,000 to 20,000 HIV-infected children. As of June 30, 1993, the Centers for Disease Control and Prevention (CDC) reported 4,710 known AIDS cases in children twelve years-old and younger. At that point, New York City reported 1,124 pediatric AIDS cases which represented twenty-four percent of all cases in the United States.With the rising number of HIV-infected children, the medical community in the United States has begun to search for HIV-and AIDS-related treatments particularized for children. In addition to establishing guidelines for HIV-infected children's frequent check-ups and timely immunizations, the medical community has initiated research studies involving HIV-infected children.

Introduction: Stroke hospitalization and mortality are influenced by various social determinants. This ecological study aimed to determine the associations between social determinants and stroke hospitalization and outcome at county-level in the United States. Methods: County-level data were recorded from the Centers for Disease Control and Prevention as of January 7, 2020. We considered four outcomes: all-age (1) Ischemic and (2) Hemorrhagic stroke Death rates per 100,000 individuals (ID and HD respectively), and (3) Ischemic and (4) Hemorrhagic stroke Hospitalization rate per 1,000 Medicare beneficiaries (IH and HH respectively). Results: Data of 3,225 counties showed IH (12.5 ± 3.4) and ID (22.2 ± 5.1) were more frequent than HH (2.0 ± 0.4) and HD (9.8 ± 2.1). Income inequality as expressed by Gini Index was found to be 44.6% ± 3.6% and unemployment rate was 4.3% ± 1.5%. Only 29.8% of the counties had at least one hospital with neurological services. The uninsured rate was 11.0% ± 4.7% and people living within half a mile of a park was only 18.7% ± 17.6%. Age-adjusted obesity rate was 32.0% ± 4.5%. In regression models, age-adjusted obesity (OR for IH: 1.11; HH: 1.04) and number of hospitals with neurological services (IH: 1.40; HH: 1.50) showed an association with IH and HH. Age-adjusted obesity (ID: 1.16; HD: 1.11), unemployment (ID: 1.21; HD: 1.18) and income inequality (ID: 1.09; HD: 1.11) showed an association with ID and HD. Park access showed inverse associations with all four outcomes. Additionally, population per primary-care physician was associated with HH while number of pharmacy and uninsured rate were associated with ID. All associations and OR had p ≤0.04. Conclusion: Unemployment and income inequality are significantly associated with increased stroke mortality rates.

ABSTRACT The emergence of fluoroquinolone resistance in sterile-site isolates of Streptococcus pneumoniae is documented in this study characterizing all invasive levofloxacin-resistant (MIC, ≥8 mg/liter) S. pneumoniae isolates (n = 50) obtained from the Centers for Disease Control and Prevention Active Bacterial Core Surveillance from 1998 to 2002. Resistance among all isolates increased from 0.1% in 1998 to 0.6% in 2001 (P = 0.008) but decreased to 0.4% in 2002, while resistance among vaccine serotypes continued to increase from 0.3% in 1998 to 1.0% in 2002, suggesting that fluoroquinolones continue to exert selective pressure on these vaccine serotypes. Only 22% of resistant isolates were not covered by the conjugate vaccine serogroups. Multilocus sequence typing revealed that 58% of resistant strains were related to five international clones identified by the Pneumococcal Molecular Epidemiology Network, with the Spain23F-1 clone being most frequent (16% of all isolates). Thirty-six percent of the isolates were coresistant to penicillin, 44% were coresistant to macrolides, and 28% were multiresistant to penicillin, macrolides, and fluoroquinolones. Fifty percent of the isolates were resistant to any three drug classes. Ninety-four percent of the isolates had multiple mutations in the quinolone resistance-determining regions of the gyrA, gyrB, parC, and parE genes. In 16% of the isolates, there was evidence of an active efflux mechanism. An unusual isolate was found that showed only a single parE mutation and for which the ciprofloxacin MIC was lower (2 mg/liter) than that of levofloxacin (8 mg/liter). Our results suggest that invasive pneumococcal isolates resistant to levofloxacin in the United States show considerable evidence of multiple resistance and of clonal spread.
