Cost calculator for mass vaccination response to a US college campus outbreak of serogroup B meningococcal disease.

Serogroup B (MenB) is the leading cause of meningococcal disease among 16- to 23-year-olds in the United States and has been responsible for all 10 college outbreaks between 2011 and 2017. Outbreak-associated costs levy a substantial and unforeseen burden on colleges/universities and surrounding communities, in part because they involve collaboration with local and state health departments to develop points-of-dispensing (PODs) outbreak response plans and rapid mass vaccination of a large at-risk student population. The MenB outbreak at Providence College in 2015 was used as a case study to develop an Excel-based Meningococcal Outbreak Cost Calculator that uses target populations for mass vaccination to estimate the costs and resources associated with a meningococcal disease outbreak response. Resources include labor, medical supply, and other nonlabor costs (eg, vaccine-related adverse event costs) over an 18-month period following the outbreak declaration. Based on the actual Providence College population partially or fully vaccinated with MenB-FHbp (Trumenba®, Bivalent rLP2086) (3-dose schedule), the calculator estimated aggregate direct costs of $1,350,963 over 18 months post-outbreak for 4,418 individuals. For planned full vaccination of the enrolled undergraduate population (4,795 individuals), the tool estimated total costs of $1,798,399. In both cases, the majority of costs were for medical supplies (88%-89%) and contract services (7%-9%). This calculator can help to plan a mass vaccination campaign for MenB outbreak control, and underscores the need to vaccinate pre-emptively against diverse disease-causing strains before an outbreak occurs.

Meningococcal Carriage Evaluation in Response to a Serogroup B Meningococcal Disease Outbreak and Mass Vaccination Campaign at a College-Rhode Island, 2015-2016.

Background: Serogroup B meningococcal disease caused 7 US university outbreaks during 2013-2016. Neisseria meningitidis can be transmitted via asymptomatic nasopharyngeal carriage. MenB-FHbp (factor H binding protein), a serogroup B meningococcal (MenB) vaccine, was used to control a college outbreak. We investigated MenB-FHbp impact on meningococcal carriage. Methods: Four cross-sectional surveys were conducted in conjunction with MenB-FHbp vaccination campaigns. Questionnaires and oropharyngeal swabs were collected from students. Specimens were evaluated using culture, slide agglutination, real-time polymerase chain reaction (rt-PCR), and whole genome sequencing. Adjusted prevalence ratios (aPRs) were calculated using generalized estimating equations. Results: During each survey, 20%-24% of participants carried any meningococcal bacteria and 4% carried serogroup B by rt-PCR. The outbreak strain (ST-9069) was not detected during the initial survey; 1 student carried ST-9069 in the second and third surveys. No carriage reduction was observed over time or with more MenB-FHbp doses. In total, 615 students participated in multiple surveys: 71% remained noncarriers, 8% cleared carriage, 15% remained carriers, and 7% acquired carriage. Ten students acquired serogroup B carriage: 3 after 1 MenB-FHbp dose, 4 after 2 doses, and 3 after 3 doses. Smoking (aPR, 1.3; 95% confidence interval [CI], 1.1-1.5) and male sex (aPR, 1.3; 95% CI, 1.1-1.5) were associated with increased meningococcal carriage. Conclusions: Carriage prevalence on campus remained stable, suggesting MenB-FHbp does not rapidly reduce meningococcal carriage or prevent serogroup B carriage acquisition. This reinforces the need for high vaccination coverage to protect vaccinated individuals and chemoprophylaxis for close contacts during outbreaks.

Rapid response to a college outbreak of meningococcal serogroup B disease: Nation's first widespread use of bivalent rLP2086 vaccine.

OBJECTIVE: To outline the reasoning behind use of bivalent rLP2086 in a Rhode Island college meningococcal B disease outbreak, highlighting the timeline from outbreak declaration to vaccination clinic, emphasizing that these two time points are <3 days apart. PARTICIPANTS: Staff, faculty, and students at College X eligible for vaccination. METHODS: An outbreak response was initiated, advantages/disadvantages of available MenB vaccines were discussed, and a vaccination clinic was coordinated. RESULTS: Bivalent rLP2086 was chosen as the vaccination intervention. We achieved a 94% coverage rate for the first dose. To date, this intervention has prevented further cases of Neisseria meningitidis serogroup B disease at College X. CONCLUSIONS: The close, efficient collaboration of public health stakeholders and College X led 94% of the eligible population to be safely vaccinated with at least one dose of bivalent rLP2086. This outbreak marked the first time bivalent rLP2086 was effectively used as an intervention response.

Serogroup B Meningococcal Disease Outbreak and Carriage Evaluation at a College - Rhode Island, 2015.

On February 2, 2015, the Rhode Island Department of Health was notified of a case of meningococcal disease in a male undergraduate student at Providence College. Three days later, a second case was reported in a male undergraduate with no contact with the first student, indicating an attack rate of 44 cases per 100,000 students, nearly 500 times higher than the national incidence of 0.15 cases per 100,000 among persons aged 17-22 years (Division of Bacterial Diseases, National Center for Immunization and Respiratory Diseases, CDC, unpublished data, 2013). Both cases were caused by a rare outbreak strain of Neisseria meningitidis serogroup B (ST-9069); neither case was fatal. In response to the outbreak, potential contacts received antibiotic chemoprophylaxis, and a mass vaccination campaign with a recently licensed serogroup B meningococcal (MenB) vaccine was implemented. In collaboration with CDC, the first phase of a meningococcal carriage evaluation was undertaken.

Postcrisis redevelopment of sustainable healthcare systems.

OBJECTIVE: Research and field experience have identified a global gap in postdisaster rebuilding of healthcare systems due to the current primary focus on returning devastated community infrastructures to predisaster conditions. Disasters, natural or man-made, present an opportunity for communities to rebuild, restructure, and redefine their predisaster states, creating more resilient and sustainable healthcare systems. DESIGN: A model for sustainable postdisaster healthcare rebuilding was developed by bridging identified gaps in the literature on the processes of developing healthcare systems postdisaster and utilizing evidence from the literature on postdisaster community reconstruction. RESULTS: The proposed model-the Sustainable Healthcare Redevelopment Model-is designed to guide communities through the process of recovery, and identifies four stages for rebuilding healthcare systems: (1) response, (2) recovery, (3) redevelopment, and (4) sustainable development. Implementing sustainable healthcare redevelopment involves a bottom-up approach, where community stakeholders have the ability to influence policy decisions. Relationships within internal government agencies and with public-private partnerships are necessary for successful recovery. CONCLUSION: The Sustainable Healthcare Redevelopment Model can serve as a guideline for delivery of healthcare services following disaster or conflict and use of crisis as a window of opportunity to improve the healthcare delivery system and incorporate resilience into the healthcare infrastructure.

Rheumatic manifestations preceding adult acute leukemia: characteristics and implication in course and prognosis.

The manifestations and outcome of adult patients with acute leukemia (AL) were examined to study the characteristics of the rheumatological prodrome of AL and to find whether it is a marker of a distinct clinical and laboratory course and whether it has any prognostic implication. During a 10-year period, 8/139 (5.8%) of AL patients presented with rheumatic manifestations. The average duration of the arthritis syndrome preceding the diagnosis of AL was 3.25 months. The most common pattern of presentation was a reactive arthritis-like syndrome involving the large joints asymmetrically and associated with low back pain. Distinctive features suggesting a paraneoplastic arthritis were severe pain disproportionate to physical findings, a poor response to conventional antirheumatic treatment, and early significant osteopenia or lytic bone lesions. The epidemiological, clinical and laboratory characteristics of patients with or without rheumatic manifestations were comparable, except for fever on presentation, the presence of transient metabolic derangement following chemotherapy, and the initial average hemoglobin, hematocrit and serum uric acid values. Moreover, the initial outcome of the two groups was similar, as the early mortality rates were comparable (42.8% vs. 45% for patients with or without arthritis, respectively). In conclusion, rheumatic syndrome presentation of adult AL is uncommon, and apparently has no deleterious effects on initial prognosis. A timely diagnosis requires an increased awareness to distinctive features.

[Red cell Na+/H+ exchange and role of protein kinase C in its stimulation in diabetes mellitus, essential hypertension and nephropathy].

Na+/H+ exchange (NHE) was measured as maximal initial velocity of pH-dependent H+ efflux from red cells into an alkaline medium containing Na+ in patients with insulin-dependent or noninsulin-dependent diabetes, with and without hypertension and in normoglycemic, essential hypertensives and normal controls (50 subjects in each subgroup). Maximal velocities of NHE were found in microalbuminuric patients in all subgroups, and NHE correlated with the rate of micro-albuminuria (r = 0.61, p = 0.02). Daily insulin requirements were greater in those with elevated NHE (84 +/- 8 vs 42 +/- 4 U/day). There was no correlation between NHE and levels of plasma glucose, HbA1 and plasma aldosterone and lipid profile and PRA. NHE was correlated with plasma prolactin (r = 0.51, p = 0.02) and PTH r = 0.24, p = 0.05). In uremic patients, NHE was inversely correlated with creatinine clearance (r = -0.48, p = 0.03). Since calphostin C, a selective inhibitor of protein kinase C, lowered increased NHE in vitro, the protein kinase C-dependent pathway of the exchanger regulation was concluded to be responsible for NHE activation in diabetes mellitus and essential hypertension.

[The results of toxicological research on dental alloys containing Ni, Cr and Co using the implantation method]. / Rezul'taty toksikologicheskogo issledovaniia stomatologicheskikh splavov, soderzhashchikh Ni, Cr, Co, metodom implantatsii.

Biocompatibility of 7 dentistry alloys containing 5 do 70% of Ni but not containing Be was studied by implantation of these alloys into femoral muscles of 360 white rats. Tissue directly adjacent to alloy samples, regional lymph nodes, and viscera were under study. The detected changes were approximately similar in different animal groups and similar to the changes in the reference group, this permitting the authors to consider the suggested allows biologically indifferent.

[An electron probe x-ray microanalysis of dental alloys]. / Elektronno-zondovyi rentgenovskii mikroanaliz nekotorykh stomatologicheskikh splavov.

Electron probe x-ray microanalysis of 3 commercial cobalt-chromium-based alloys, CCA (USSR), Biosil and Vakukast (FRG), has revealed that CCA is initially heterogenic, this being explained, probably, by elevated chromium content. Biosil and Vakukast are similar in composition and represent a matrix with eutectic insertions of intermetallides and a small amount of oxides. Physical and mechanical characteristics of these alloys are described.

Eye-sighting preference of normal and hemiplegic children and adults.

Monocular eye-sighting preference was examined in 32 children with hemiplegia, 51 adult-onset hemiplegic patients and 57 normal children and adults. Eye preference was compared with ear preference on dichotic listening for 25 of the hemiplegic children. No independent association could be detected between eye preference and ear preference. In both the children and adults with hemiplegia the preferred eye tended to be on the same side as the damaged hemisphere. Among the adults, this tendency was more pronounced with more extensive lesions, as manifested by aphasia and/or hemianopia. These findings are interpreted as indicating that eye-sighting preference is unrelated to unitary hemispheric dominance, and that, unlike dominance for hearing and speech, it is not irreversible after a critical period of development. A simpler explanation than incomplete hemispheric dominance is offered for the weakly positive association between mixed laterality and cerebral dysfunction.

Auditory perception in early lateralized brain damage.

In a study of hemispheric dominance for the perception of speech the performance of 28 young children with congenital or infantile hemiplegia was compared with that of their normal peers and recently brain damage nonaphasic adults. Our results confirm Goodglass's findings that in children with early left hemisphere damage the transfer of dominance for speech processing is completed in childhood, and they show that this process of hemispheric transfer can be completed by 3 years of age. Comparison with results on adults with CVA provides additional evidence that in early lateralized brain cognitive functions normally dominant in one cerebral hemisphere are developed in the alternative hemisphere in a way that apparently does not happen later in life.
