Children's understanding of epilepsy: A qualitative study.

PURPOSE: To use a qualitative research approach to determine children's understandings of epilepsy and their epilepsy treatment. METHODS: Children aged 7-16 years with physician-confirmed active epilepsy (i.e., having had an epileptic seizure in the past year and or currently taking antiepileptic drugs (AEDs), and not known to have an intellectual disability, were invited to participate. Children had semi-structured interviews separately on two occasions. Between the first and second interviews, an observation of a routine epilepsy clinic appointment of individual children was conducted, and was then discussed during the second interview. Participatory research tools were used in both child interviews to facilitate discussions. Interviews were audio recorded and transcribed, pseudonymized and entered into NVivo (version 12, QSR International). Data were analyzed using a thematic approach. RESULTS: Twenty-three children of mean age 10.1 years (range 8-14), mean duration of epilepsy of 4.6 years (range 2-10) were enrolled. Twelve were 12 female; 7 had focal, 14 had generalized, and 2 had combined epilepsy; 20 were on monotherapy; and 16 had tried previous AEDs. All had an initial (first) interview; 20 were observed during a clinic appointment and had a second interview. Five broad themes emerged: understanding of epilepsy; understanding of seizures; understanding of medication; understanding of children's role in clinical appointments; influences on children's understanding. Children spoke about what epilepsy meant by describing the physical sensations of having a seizure or through the act of taking medication. Children described the role they had, or felt they should have, but reported challenges in being meaningfully involved in clinical appointments. While healthcare professionals were initial information nodes, epilepsy information from parents appeared to be more significant for children. CONCLUSIONS: The perspectives of children with epilepsy are valuable for clinicians to understand; assumptions should not be made that children's views can be accessed via parents. Clinicians need to be constantly aware of children's views and ways of understanding and communicating about their epilepsy. To support this, the research - drawing on children's words, meanings, and stories - was used to inform an easily accessible, gender-neutral, animation about epilepsy that provides information about the condition, seizures, and medication (https://youtu.be/MO7xXL2ZXP8).

Multiple endocrine neoplasia: an update.

The multiple endocrine neoplasia (MEN) syndromes include MEN1, MEN2 (formerly MEN2A), MEN3 (formerly MEN2B) and the recently identified MEN4. Clinical presentations are varied and often relate to the overproduction of specific hormones. Understanding the genetics of each syndrome assists in determining screening timelines. Treatments for each manifestation are dependent on location, risk of recurrence or malignancy, hormone excess and surgical morbidity. Multidisciplinary management should include geneticists, genetic counsellors, endocrinologists and endocrine surgeons.

Identification of inhibitors of N5-carboxyaminoimidazole ribonucleotide synthetase by high-throughput screening.

The increasing risk of drug-resistant bacterial infections indicates that there is a growing need for new and effective antimicrobial agents. One promising, but unexplored area in antimicrobial drug design is de novo purine biosynthesis. Recent research has shown that de novo purine biosynthesis in microbes is different from that in humans. The differences in the pathways are centered around the synthesis of 4-carboxyaminoimidazole ribonucleotide (CAIR) which requires the enzyme N(5)-carboxyaminoimidazole ribonucleotide (N(5)-CAIR) synthetase. Humans do not require and have no homologs of this enzyme. Unfortunately, no studies aimed at identifying small-molecule inhibitors of N(5)-CAIR synthetase have been published. To remedy this problem, we have conducted high-throughput screening (HTS) against Escherichia coliN(5)-CAIR synthetase using a highly reproducible phosphate assay. HTS of 48,000 compounds identified 14 compounds that inhibited the enzyme. The hits identified could be classified into three classes based on chemical structure. Class I contains compounds with an indenedione core. Class II contains an indolinedione group, and Class III contains compounds that are structurally unrelated to other inhibitors in the group. We determined the Michaelis-Menten kinetics for five compounds representing each of the classes. Examination of compounds belonging to Class I indicates that these compounds do not follow normal Michaelis-Menten kinetics. Instead, these compounds inhibit N(5)-CAIR synthetase by reacting with the substrate AIR. Kinetic analysis indicates that the Class II family of compounds are non-competitive with both AIR and ATP. One compound in Class III is competitive with AIR but uncompetitive with ATP, whereas the other is non-competitive with both substrates. Finally, these compounds display no inhibition of human AIR carboxylase:SAICAR synthetase indicating that these agents are selective inhibitors of N(5)-CAIR synthetase.

Evaluation of pharmacy generalists performing antimicrobial stewardship services.

PURPOSE: Improvements in medication use achieved by pharmacy generalists using a care bundle approach to antimicrobial stewardship are reported. METHODS: A six-month prospective, repeated-treatment, quasi-experimental study involving three month-long intervention periods and three month-long control periods was conducted in the setting of an existing antimicrobial stewardship program at a large hospital. The intervention involved prospective audit and feedback conducted by pharmacy generalists who were trained in an antimicrobial stewardship care bundle approach. During control months, a pharmacy generalist who was not trained in antimicrobial stewardship rounded with the multidisciplinary team and provided standard-of-care pharmacy services. The primary endpoint was compliance with a care bundle of four antimicrobial stewardship metrics: documentation of indication for therapy in the medical record, selection of empirical therapy according to institutional guidelines, documented performance of indicated culture testing, and deescalation of therapy when indicated. RESULTS: Two-hundred eighty-six patients were enrolled in the study: 124 in the intervention group and 162 in the control group. The cumulative rate of full compliance with all care bundle components during the six-month study was significantly greater during intervention months than during control months (68.5% versus 45.7%, p < 0.001). After adjusting for infection type, antimicrobial stewardship provided by an intervention-group pharmacist was associated with improved care bundle compliance (adjusted odds ratio, 2.70; p < 0.001). No significant differences in patient outcomes during intervention and control months were detected. CONCLUSION: Pharmacy generalists trained to comply with a systematic care bundle approach enhanced the quality of antimicrobial management.
