ABSTRACT

BACKGROUND: Surveillance of influenza-like illness (ILI) in the United States is primarily conducted through medical settings despite a significant burden of non-medically attended ILI. OBJECTIVES: To assess consistency between surveillance for respiratory viruses in outpatient and community settings using ILI surveillance from the Centers for Disease Control and Prevention Influenza Incidence Surveillance Project (IISP) and the Mobile Surveillance for Acute Respiratory Infections (ARI) and Influenza-Like Illness in the Community (MoSAIC) Study. METHODS: The Influenza Incidence Surveillance Project conducts ILI surveillance in 3 primary care clinics in New York City, and MoSAIC conducts community-based ILI/ARI surveillance through text messaging among a cohort of New York City residents. Both systems obtain respiratory specimens from participants with ILI/ARI and test for multiple pathogens. We conducted a retrospective review of ILI cases in IISP and MoSAIC from January 2013 to May 2015 with descriptive analyses of clinical and laboratory data. RESULTS: Five-hundred twelve MoSAIC and 669 IISP participants met an ILI criteria (fever with cough or sore throat) and were included. Forty percent of MoSAIC participants sought care; the majority primary care. Pathogens were detected in 63% of MoSAIC and 70% of IISP cases. The relative distribution of influenza and other respiratory viruses detected was similar; however, there were statistically significant differences in the frequency that were not explained by care seeking. CONCLUSIONS: Outpatient and community-based surveillance in the one found similar timing and relative distribution of respiratory viruses, but community surveillance in a single neighborhood may not fully capture the variations in ILI etiology that occur more broadly.

ABSTRACT

BACKGROUND: Highly pathogenic avian influenza A (HPAI) viruses found in poultry and wild birds occasionally infect humans and can cause serious disease. In 2014, the Advisory Committee on Immunization Practices (ACIP) reviewed data from one licensed ASO3-adjuvanted influenza A(H5N1) vaccine for consideration of use during inter-pandemic periods among persons with occupational exposure. To guide vaccine policy decisions, we conducted a survey of laboratory workers to assess demand for HPAI vaccination. METHODS: We designed an anonymous web survey (EpiInfo 7.0) to collect information on demographics, type of work and time spent with HPAI viruses, and interest in HPAI vaccination. Eligible participants were identified from 42 entities registered with United States Department of Agriculture's Agricultural Select Agent program in 2016 and emailed electronic surveys. Personnel with Biosafety Level 3 enhanced (BSL-3E) laboratory access were surveyed. Descriptive analysis was performed. RESULTS: Overall, 131 responses were received from 33 principal investigators, 26 research scientists, 24 technicians, 15 postdoctoral fellows, 6 students, and 27 others. The estimated response rate was 15% among the laboratory personnel of responding principal investigators. One hundred respondents reported working in a BSL-3E area where HPAI experiments occurred with a mean time of 5.1-11.7 h per week. Overall, 49% were interested in receiving an A(H5N1) vaccine. By role, interest was highest among students (80%) and among those who spent >50% of their time in a BSL-3E area (64%). Most (61%) of those who said they might be or were not interested in vaccine believed it would not provide additional protection to current safety practices. CONCLUSIONS: Half of responding laboratory workers was interested in receiving an influenza A(H5N1) vaccine. HPAI vaccination of laboratory workers at risk of occupational exposure could be used along with existing safety practices to protect this population.

ABSTRACT

Although a diagnosis of pyridoxine-dependent seizures may commonly be delayed, this case involves an extremely late diagnosis with associated morbidity. Our patient received pyridoxine during the neonatal period, in conjunction with other antiepileptic drugs that masked its effect. This patient also underwent ventriculoperitoneal shunting, which complicated the diagnosis. Pyridoxine was continued with other antiepileptic drugs, without definite recognition of its therapeutic relationship. Pyridoxine-dependent seizures were finally recognized at age 19 years when the patient manifested refractory status epilepticus, several days after wisdom tooth removal (and discontinuing oral medications including pyridoxine and phenobarbital before surgery). The diagnosis was only established via genetic testing. Our patient highlights the difficulty in diagnosing this rare seizure type and its potential importance in refractory epilepsy.

ABSTRACT

Perinatal hyperoxia attenuates the adult hypoxic ventilatory response in rats. Hyperoxia might elicit this plasticity by inhibiting chemoreceptor activity during early life. Thus, we hypothesized that stimulating chemoreceptors with CO(2) during hyperoxia or interrupting hyperoxia with periods of normoxia would reduce the effects of hyperoxia on the hypoxic ventilatory response. Rats were born and raised in 60% O(2) for the first two postnatal weeks. Two groups were simultaneously exposed to either sustained hypercapnia (5% CO(2)) or intermittent hypercapnia (alternating 1-h exposures to 0 and 7.5% CO(2)) while another group was exposed to only intermittent hyperoxia (alternating 1-h exposures to 21 and 60% O(2)). Hypoxic ventilatory responses were assessed at 6-10 weeks of age by whole-body plethysmography. Rats exposed to intermittent hypercapnia during hyperoxia or to intermittent hyperoxia exhibited greater increases in ventilation-to-metabolism ratio ( VE/VO2 ) in response to 12.5% O(2) than rats exposed to hyperoxia alone (both P<0.05), although responses were generally less than those of normoxia-reared controls; a similar trend was observed for rats exposed to sustained hypercapnia during hyperoxia (P=0.053). These data suggest that activity-dependent mechanisms contribute to hyperoxia-induced developmental plasticity, although contributions from additional mechanisms cannot be excluded.
