BackgroundBenzathine penicillin G (BPG) is the only recommended treatment to prevent mother-to-child transmission of syphilis. Due to recent reports of country-level shortages of BPG, an evaluation was undertaken to quantify countries that have experienced shortages in the past 2 years and to describe factors contributing to these shortages.Methods and findingsCountry-level data about BPG shortages were collected using 3 survey approaches. First, a survey designed by the WHO Department of Reproductive Health and Research was distributed to 41 countries and territories in the Americas and 41 more in Africa. Second, WHO conducted an email survey of 28 US Centers for Disease Control and Prevention country directors. An additional 13 countries were in contact with WHO for related congenital syphilis prevention activities and also reported on BPG shortages. Third, the Clinton Health Access Initiative (CHAI) collected data from 14 countries (where it has active operations) to understand the extent of stock-outs, in-country purchasing, usage behavior, and breadth of available purchasing options to identify stock-outs worldwide. CHAI also conducted in-person interviews in the same 14 countries to understand the extent of stock-outs, in-country purchasing and usage behavior, and available purchasing options. CHAI also completed a desk review of 10 additional high-income countries, which were also included. BPG shortages were attributable to shortfalls in supply, demand, and procurement in the countries assessed. This assessment should not be considered globally representative as countries not surveyed may also have experienced BPG shortages. Country contacts may not have been aware of BPG shortages when surveyed or may have underreported medication substitutions due to desirability bias. Funding for the purchase of BPG by countries was not evaluated. In all, 114 countries and territories were approached to provide information on BPG shortages occurring during 2014–2016. Of unique countries and territories, 95 (83%) responded or had information evaluable from public records. Of these 95 countries and territories, 39 (41%) reported a BPG shortage, and 56 (59%) reported no BPG shortage; 10 (12%) countries with and without BPG shortages reported use of antibiotic alternatives to BPG for treatment of maternal syphilis. Market exits, inflexible production cycles, and minimum order quantities affect BPG supply. On the demand side, inaccurate forecasts and sole sourcing lead to under-procurement. Clinicians may also incorrectly prescribe BPG substitutes due to misperceptions of quality or of the likelihood of adverse outcomes.ConclusionsTargets for improvement include drug forecasting and procurement, and addressing provider reluctance to use BPG. Opportunities to improve global supply, demand, and use of BPG should be prioritized alongside congenital syphilis elimination efforts.

The NCCN Guidelines for Acute Lymphoblastic Leukemia (ALL) focus on the classification of ALL subtypes based on immunophenotype and cytogenetic/molecular markers; risk assessment and stratification for risk-adapted therapy; treatment strategies for Philadelphia chromosome (Ph)-positive and Ph-negative ALL for both adolescent and young adult and adult patients; and supportive care considerations. Given the complexity of ALL treatment regimens and the required supportive care measures, the NCCN ALL Panel recommends that patients be treated at a specialized cancer center with expertise in the management of ALL This portion of the Guidelines focuses on the management of Ph-positive and Ph-negative ALL in adolescents and young adults, and management in relapsed settings.

Hepatic metastasis from colorectal cancer (mCRC) is best treated with a multidisciplinary approach. Conflicting data exist regarding the impact of preoperative chemotherapy on morbidity and mortality after hepatectomy. We hypothesized that preoperative chemotherapy does not adversely impact complications or mortality associated with hepatectomy. A retrospective analysis was performed and included patients with mCRC who underwent hepatectomy from 1996 to 2006. Patients were separated into two groups: those who received preoperative chemotherapy and those who did not. Univariate and multivariate analyses were performed to determine the factors associated with morbidity and mortality. Kaplan-Meier analyses were performed to determine disease-free survival (DFS) and overall survival (OS). One hundred eighty-six patients were analyzed: 112 (60%) received preoperative chemotherapy for a median of 4.2 months. Eighty patients (43%) underwent major hepatectomy. When comparing the two groups, there were no differences in hepatic tumor size (median 3 cm; p = 0.35), type of resection (p = 0.62), stage (p = 0.44) or location (p = 0.10) of the primary tumor, preoperative carcinoembryonic antigen (CEA) level (p = 0.80), or number of nodes in lymphadenectomy (p = 0.62). Only number of positive nodes after colectomy (p = 0.02), age (p < or = 0.0001), and combined resection/radiofrequency ablation (RFA) (p = 0.004) were statistically different between the two groups. There was no difference in rates of morbidity (p = 0.81), mortality (p = 0.29), DFS (p = 0.25) or OS (p = 0.30). We conclude that the use of preoperative chemotherapy did not increase the risk of complications or death for patients undergoing hepatectomy for metastatic colorectal cancer. Pre-hepatectomy chemotherapy appears to be safe and is an important part of the multidisciplinary approach for this disease.

Palliative care has evolved to be an integral part of comprehensive cancer care with the goal of early intervention to improve quality of life and patient outcomes. The NCCN Guidelines for Palliative Care provide recommendations to help the primary oncology team promote the best quality of life possible throughout the illness trajectory for each patient with cancer. The NCCN Palliative Care Panel meets annually to evaluate and update recommendations based on panel members’ clinical expertise and emerging scientific data. These NCCN Guidelines Insights summarize the panel’s recent discussions and highlights updates on the importance of fostering adaptive coping strategies for patients and families, and on the role of pharmacologic and nonpharmacologic interventions to optimize symptom management.

Commercial mayonnaise and refrigerated ranch salad dressing were inoculated at two levels with two strains of Escherichia coli O157:H7, a non-pathogenic E. coli, and the non-fecal coliform Enterobacter aerogenes. Results showed that at the high inoculation level (&gt;106 colony forming units [CFU]/g) in mayonnaise stored at room temperature (ca. 22°C) both strains of O157:H7 were undetected at 96 h. At the high inoculation level, all strains of coliform bacteria tested survived longer in salad dressing stored at 4°C than in mayonnaise stored at 22°C. The O157:H7 strains were still present at low levels after 17 days. The survival time in the low-level inoculum (104CFU/g) study decreased, but the survival pattern in the two products was similar to that observed in the high-level inoculum study. Slight differences in survival among strains were observed. The greater antimicrobial effect of mayonnaise may be attributable to differences in pH, water activity (aw), nutrients, storage temperature, and the presence of lysozyme in the whole eggs used in the production of commercial mayonnaise. Coliform bacteria survived longer in refrigerated salad dressing than in mayonnaise particularly at the high-level inoculum. Both mayonnaise (pH 3.91) and salad dressing (pH 4.51) did not support the growth of any of the microorganisms even though survival was observed.
