Severe neonatal jaundice (SNNJ) is a leading cause of neonatal morbidity and mortality in low- and middle-income countries (LMICs). Risk mitigation and management modalities for SNNJ have led to a marked reduction in complications in high-income countries but not in LMICs likely in part due to knowledge gaps among healthcare providers. This study, a cross-sectional study conducted in Ogbomosho, Nigeria, aimed to identify SNNJ knowledge and practices among Nigerian healthcare providers/trainees. Healthcare providers/trainees completed a structured questionnaire. Healthcare providers/trainees included are nurse midwives (33.4%), nurses (18.6%), nursing students (15.2%), traditional birth attendants (TBAs) (12.7%), physicians (10.2%), and medical students (9.9%). Most physicians were aware of the common causes of SNNJ; however, knowledge deficits in other groups were notable. Despite most providers endorsing that glucose-6-phosphate dehydrogenase deficiency can cause SNNJ (91% of physicians, 60% of nurses, 71% of midwives, 81% of medical students, 43% of nursing students, 7% of TBAs), very few providers recognized that it is common, ranging from 3% in nurses up to a high of 47% among medical students. Gaps in provider knowledge regarding preventative measures and sequela were also noted. These data identified significant knowledge gaps regarding the etiology of SNNJ among healthcare providers/trainees, which can lead to missed opportunities in effective prevention and treatment. These deficits must be addressed if we are to eliminate tragic and preventable complications from SNNJ in Nigeria and other LMICs.
Compared with all Minnesotans, the Hmong have an increased incidence of cancers related to infectious agents. These findings indicate a need for cancer prevention and screening programs in this population.
Introduction
The objective of this clinical trial was to compare the effects of e-cigarettes with and without nicotine on patterns of combustible cigarette use and biomarkers of exposure to tobacco toxicants among African American smokers.
Methods
African American smokers (n = 234) were enrolled in a 12-week, single blind, randomized controlled trial and assigned to ad lib use of nicotine e-cigarettes with or without menthol (2.4% nicotine [equivalent to combustible cigarettes], n = 118), or no-nicotine e-cigarettes (n = 116) for 6 weeks. Surveys were administered at baseline, 2, 6, and 12 weeks, and urinary biomarkers 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) and total nicotine equivalents (TNE) were assessed at baseline and 6 weeks.
Results
Participants smoked an average of 11.4 cigarettes per day (CPD) and 88% used menthol cigarettes at baseline. At Week 6, the nicotine group reported using e-cigarettes 9.1 times per day compared to 11.4 times in the no-nicotine group (p = 0.42). Combustible cigarette smoking decreased 3.0 CPD in the nicotine group compared to 2.7 CPD in the no-nicotine group (p = 0.74). Neither TNE nor NNAL changed significantly between baseline and Week 6. There were no differences in nicotine withdrawal symptoms between treatment groups. Smoking reduction persisted in both groups at Week 12.
Conclusions
Contrary to our hypotheses, nicotine e-cigarettes did not significantly reduce the use of combustible cigarettes compared to no-nicotine e-cigarettes in this cohort of African American smokers. Findings suggest e-cigarettes are modestly associated with the decreased use of combustible cigarettes among non-treatment seeking smokers, regardless of nicotine content, but without a reduction in tobacco toxicants.
Implications
Although e-cigarettes have the potential to reduce harm if substituted for combusted cigarettes (or if they promoted cessation) because of lower levels of tobacco toxicants, this study suggests ad lib use of e-cigarettes among African American smokers, with or without nicotine, results in modest smoking reduction but does not change toxicant exposure in a cohort where smoking cessation or reduction is not the goal. These data suggest that testing future harm reduction interventions using e-cigarettes should include more specific behavioral change coaching, including substituting for or completely stopping combusted cigarettes.

Good syndrome (GS) is a rare paraneoplastic syndrome seen before or after diagnosis of thymoma, and its treatment, and is characterized by hypogammaglobulinemia. Rarely, pure white cell aplasia (PWCA) can also be seen which can present as recurrent neutropenia. We describe a 64-year-old man with recurrent sinus infections and previous thymectomy for stage 1 type B2 thymoma presenting with chronic diarrhea and recurrent neutropenia necessitating serial hospitalizations despite repeated antimicrobial treatment. Immunoglobulin levels, including IgM, IgA, IgD, and IgE were undetectable. Flow cytometry also showed absent B cells. Patient was initiated on immunoglobulin replacement therapy with consequent significant clinical improvement. Despite thymectomy, patients can develop thymoma-associated paraneoplastic syndromes, including GS.
Cefepime, a widely used fourth-generation cephalosporin for coverage of both gram-positive and gram-negative bacteria, has been reported to have associated neurological adverse effects. These effects have been seen mostly in patients mostly with impaired renal function, and currently, dosing is based on creatinine clearance to reduce its toxic effect profile. Despite renal dose adjustment, we present a case of a 40-year-old woman who was managed for

bacteremia, acute kidney injury, and hemorrhagic shock. About 96 hours after cefepime therapy was commenced, she was noted to be twitching with passive movement of her upper limb and myoclonus of the facial muscles. Her workup including computed tomography (CT) scan of the head and magnetic resonance imaging (MRI) brain were negative. Electroencephalograph (EEG) showed 2 Hertz sharply contoured triphasic form rhythmic waves suggestive of nonconvulsive status epilepticus (NCSE). She received antiseizure medications and later had hemodialysis for effective clearance of cefepime. She had significant improvement in her neurological status following hemodialysis and a repeat EEG showed no further seizure activity. Clinicians should be aware of the risk of NCSE in patients on cefepime despite renal dose adjustment. Once identified, immediate discontinuation of the offending drug, treatment with benzodiazepines, and clearance of the medication with hemodialysis is recommended.
