The estimated US burden of CAP is substantial, with >1.5 million unique adults being hospitalized annually, 100000 deaths occurring during hospitalization, and approximately 1 of 3 patients hospitalized with CAP dying within 1 year.

Our study demonstrated real-world, direct effectiveness of 13-valent pneumococcal conjugate vaccine against vaccine-type community-acquired pneumonia following introduction into a routine immunization program among adults aged ≥65 years, many of whom had immunocompromising and chronic medical conditions.

Factors affecting the growth and survival of salmonellae in the experimental manufacture of 7 lots of Colby and 65 lots of' Cheddar cheese were studied. Milk was artificially contaminated just prior to making of cheese. Manufacturing variables tested included effects of milk pasteurization, size of starter inoculum, titratable acidity and cheese pH, type of lactic culture, chemical additives, salt and moisture content, supplemental cheese microorganisms, and curing temperatures. The rate and amount of acid produced during making, the pH of the cheese, and the type and size of starter inoculum had significant effect in suppressing the growth and survival of salmonellae. Salt, moisture, chemical additives and pasteurization of the milk, had little or no effect on the salmonellae. Addition of large numbers of Propionibacterium and Leuconostoc seemed to favor survival of salmonellae. Lactobacilli and enterococci tested had no effect.

Objectives The influence of socioeconomic disparities on adults with pneumonia is not well understood. The objective of our study was to evaluate the relationship between community-level socioeconomic position, as measured by an area deprivation index, and the incidence, severity, and outcomes among adults with community-acquired pneumonia (CAP). Methods This was an ancillary study of a population-based, prospective cohort study of patients hospitalized with CAP in Louisville, Kentucky, from June 1, 2013, through May 31, 2015. We used a race-specific, block group–level area deprivation index as a proxy for community-level socioeconomic position and evaluated it as a predictor of CAP incidence, CAP severity, early clinical improvement, 30-day mortality, and 1-year mortality. Results The cohort comprised 6349 unique adults hospitalized with CAP. CAP incidence per 100 000 population increased significantly with increasing levels of area deprivation, from 303 in tertile 1 (low deprivation), to 467 in tertile 2 (medium deprivation), and 553 in tertile 3 (high deprivation) ( P < .001). Adults in medium- and high-deprivation areas had significantly higher odds of severe CAP (tertile 2 odds ratio [OR] = 1.2 [95% confidence interval (CI), 1.06-1.39]; tertile 3 OR = 1.4 [95% CI, 1.18-1.64] and 1-year mortality (tertile 2 OR = 1.3 [95% CI, 1.11-1.54], tertile 3 OR = 1.3 [95% CI, 1.10-1.64]) than adults in low-deprivation areas. Conclusions Compared with adults residing in low-deprivation areas, adults residing in high-deprivation areas had an increased incidence of CAP, and they were more likely to have severe CAP. Beyond 30 days of care, we identified an increased long-term mortality for persons in high-deprivation areas. Community-level socioeconomic position should be considered an important factor for research in CAP and policy decisions.
