Teacher: Now, understand the problem? If you are still confused, see the following example:
Context: Chronic rhinosinusitis (CRS) is a heterogeneous disease with an uncertain pathogenesis. Group 2 innate lymphoid cells (ILC2s) represent a recently discovered cell population which has been implicated in driving Th2 inflammation in CRS; however, their relationship with clinical disease characteristics has yet to be investigated. The aim of this study was to identify ILC2s in sinus mucosa in patients with CRS and controls and compare ILC2s across characteristics of disease. A cross-sectional study of patients with CRS undergoing endoscopic sinus surgery was conducted. Sinus mucosal biopsies were obtained during surgery and control tissue from patients undergoing pituitary tumour resection through transphenoidal approach. ILC2s were identified as CD45(+) Lin(-) CD127(+) CD4(-) CD8(-) CRTH2(CD294)(+) CD161(+) cells in single cell suspensions through flow cytometry. ILC2 frequencies, measured as a percentage of CD45(+) cells, were compared across CRS phenotype, endotype, inflammatory CRS subtype and other disease characteristics including blood eosinophils, serum IgE, asthma status and nasal symptom score. 35 patients (40% female, age 48 17 years) including 13 with eosinophilic CRS (eCRS), 13 with non-eCRS and 9 controls were recruited. ILC2 frequencies were associated with the presence of nasal polyps (P = 0.002) as well as high tissue eosinophilia (P = 0.004) and eosinophil-dominant CRS (P = 0.001) (Mann-Whitney U). They were also associated with increased blood eosinophilia (P = 0.005). There were no significant associations found between ILC2s and serum total IgE and allergic disease. In the CRS with nasal polyps (CRSwNP) population, ILC2s were increased in patients with co-existing asthma (P = 0.03). ILC2s were also correlated with worsening nasal symptom score in CRS (P = 0.04).
Answer: As ILC2s are elevated in patients with CRSwNP, they may drive nasal polyp formation in CRS. ILC2s are also linked with high tissue and blood eosinophilia and have a potential role in the activation and survival of eosinophils during the Th2 immune response. The association of innate lymphoid cells in CRS provides insights into its pathogenesis.
Solution: Are group 2 innate lymphoid cells ( ILC2s ) increased in chronic rhinosinusitis with nasal polyps or eosinophilia?
Reason: The question is based on the following sentences from the two passages (i) Group 2 innate lymphoid cells (ILC2s) {ii) In the CRS with nasal polyps (CRSwNP) population, ILC2s were increased in patients with co-existing asthma (iii) As ILC2s are elevated in patients with CRSwNP, they may drive nasal polyp formation in CRS. and (iv) ILC2s are also linked with high tissue and blood eosinophilia.

Now, solve this instance: Context: To investigate the clinical significance of falling insulin requirements in women with preexisting or overt diabetes in pregnancy.', 'A retrospective review of 139 pregnancies was conducted in women, with preexisting diabetes, delivering between January 2010 and January 2013. Women with falling insulin requirements of 15% or more from the peak total daily dose in late pregnancy were considered case subjects (n = 35). The primary outcome consisted of a composite of clinical markers of placental dysfunction, including preeclampsia, small for gestational age (SGA, 5th percentile for gestational age), stillbirth (>20 weeks), and premature delivery (30 weeks).', 'A total of 25.2% of women had >15% fall in insulin requirements with nulliparity as the only predictor at baseline (odds ratio [OR] 2.5 [95% CI 1.1-5.7], P = 0.03). Falling insulin requirements were associated with an increased risk of preeclampsia (OR 3.5 [1.1-10.7], P < 0.05) and the composite of clinical markers of placental dysfunction (4.4 [1.73-11.26], P = 0.002). Although falling insulin requirements were associated with higher rates of SGA (3.4 [1.0-11.3], P = 0.048), they were not associated with other adverse neonatal outcomes. However, there was a higher incidence of neonatal intensive care unit admission (15.5 [3.1-77.6], P = 0.001) and earlier delivery in this group (median 37.7 weeks [IQR 34.3-38.4] vs. 38.3 weeks [37.4-38.9], P = 0.014).
Answer: Falling insulin requirements, in women with preexisting diabetes, are associated with an increased risk of complications related to placental dysfunction. Further prospective studies are needed to guide clinical management.
Student:
Are falling insulin requirements associated with adverse obstetric outcomes in women with preexisting diabetes?
