In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Q: Context: To explore the relationship between continuous thrombocytopenia and sepsis in patients with severe burns.', 'Clinical data of 148 severely burned patients admitted to our,two burn centers from January 2007 to December 2011 and conforming to the study criteria were retrospectively analyzed. All patients were divided into sepsis group (n =44) and non-sepsis group (n = 104) according to the presence or absence of sepsis within post burn day (PBD) 30. The data of age, gender, total burn area, full-thickness burn area, fluid infusion volume within post burn hour (PBH) 24, plasma concentration of calcium ion on PBD 1, plasma concentration of albumin on PBD 1, platelet count on PBD 1, acute physiology and chronic health evaluation (APACHE) II score on admission, the presence or absence of hypovolemic shock or inhalation injury on admission, the presence or absence of disseminated intravascular coagulation (DIC) within PBH 48, operation or no operation within PBD 3, thrombocytopenia duration within PBD 10, and mortality were statistically compared between two groups to screen the independent risk factors of sepsis. Data were processed with t test, chi-square test, single factor Logistic regression analysis, and multi-factor Logistic regression analysis.', 'Between two groups, there were statistically significant differences in total burn area, full-thickness burn area, plasma concentration of calcium ion on PBD 1, plasma concentration of albumin on PBD 1, APACHE II score on admission, presence or absence of hypovolem- ic shock on admission, presence or absence of inhalation injury on admission, presence or absence of DIC within PBH 48, and mortality (with t values from 2.433 to 4.082, χ2 values from 8. 818 to 31.528, P < 0.05 or P < 0.01). Furthermore, the duration of thrombocytopenia within PBD 10 in sepsis group was (5.2 ± 2.4) d, which was significantly longer than that in non-sepsis group [(2.9 ± 1.9) d, t =6. 189, P <0.01]. There were no statistically significant differences in the other indexes between two groups (with t values from 0.971 to 1. 250, χ2 values respectively 0. 054 and 1.529, P values above 0.05). Single factor and multi-factor Logistic regression analysis indicated that APACHE II score on admission and duration of thrombocytopenia within PBD 10 were closely related to occurrence of sepsis (with odds ratio respectively 1. 140 and 1.569, P values below 0.01).\Question: Do [ Clinical significance of continuous thrombocytopenia in predicting sepsis after severe burn ]?

A: Duration of thrombocytopenia within PBD 10 is one of the risk factors for sepsis in severely burned patients, which can reflect pathophysiological changes in the body, thus providing predictive value for the occurrence of sepsis.

Q: Context: To evaluate the relevance of systematic screening for neonatal metabolic acidosis at birth as part of perinatal audit.', 'For every baby, born in Ziekenhuis Oost Limburg, Genk Belgium between 1/1/2010 and 31/12/2010, cord blood was analysed to diagnose metabolic acidosis, defined as arterial or venous pH ≤ 7.05 or 7.17 respectively, in association with base excess of ≤ -10\u2008mmol/L. Three observers identified indicators for suboptimal peripartal care with likely contribution to metabolic acidosis. In a multidisciplinary consensus meeting, these indicators were classified into 5 categories : (a) fetal monitoring error (b) labour management error, (c) instrumental vaginal delivery for fetal distress within 2\u2008h of second stage, (d) non-obstetric medical complications, (e) preterm births or accidental cases at term.', 'In a total of 2117 neonates, there were 11 intra-uterine, 1 intrapartum and 3 early neonatal deaths, bringing early perinatal mortality rate at 7.1‰. Metabolic acidosis was identified in 23 (1.1%) babies, of which 21 (91.3%) left hospital in good clinical condition. Two babies (0.9‰), born in category c, had chronic neurologic symptoms.\Question: Do identification of neonatal near miss by systematic screening for metabolic acidosis at birth?

A: Systematic screening for neonatal metabolic acidosis caused a 2.5-fold increase of case identifications eligible for perinatal audit and opened perspectives towards rationalised improvement of perinatal care, in addition to the information obtained from cases of perinatal mortality. Next to indicators of perinatal mortality, perinatal audit programs should include neonatal metabolic acidosis as an extra parameter for quality assessment of perinatal care.

Q: Context: Retinal ischemia/reperfusion (IR) is common in eye disorders. Pattern-recognition receptors (PRRs) are reported to initiate sterile inflammatory response. The role of PRRs in retinal IR injury is currently unknown. Thus, we investigated the expression and function of membrane and cytoplasmic PRRs during retinal IR.', 'Retinal IR was induced in adult Brown Norway rats by clipping the retinal vessels for 30 minutes. RNA and proteins were extracted during the course of reperfusion, and the expression levels of the following proteins were determined: Toll-like receptor 2 (TLR2), TLR4, myeloid differentiation factor 88 (MyD88), TNF receptor-associated factor 6 (TRAF6), nuclear factor-κB (NF-κB), nucleotide-binding oligomerization domain-like receptor with pyrin domain protein 1 (NLRP1), NLRP3, apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC), caspase-1, IL-1β, and IL-18. TLR4 expression in the retina was studied using immunohistochemistry. In addition, a TLR4 inhibitor was injected into the vitreous body as a therapeutic agent. After the treatment of TLR4 inhibitors, the levels of the above factors were evaluated, the apoptosis of cells in the retina, expression of cleaved-caspase-3 (c-casp-3), death of retinal ganglion cells, and the retina electroretinography was assessed.', 'After releasing the artery clamp, the retinal vessels were reperfused in 5 minutes. During the reperfusion, TLR4, MyD88, TRAF6, NF-κB, NLRP1, NLRP3, mature IL-1β, and IL-18 were upregulated, but not TLR2. In the IR model, TLR4 was highly expressed in ganglion cell and glia cell. Additionally, the inhibition of TLR4 significantly downregulated the activation of NLRP3, but not NLRP1, and the secretion of mature IL-1β and IL-18 also were inhibited. Moreover, the TLR4 inhibitor partially attenuated the injury of the retina, including alleviated retina apoptosis, downregulated c-casp-3 expression, rescued retinal ganglion cells death, and restored retina function.\Question: Is retinal ischemia/reperfusion injury mediated by Toll-like receptor 4 activation of NLRP3 inflammasomes?

A:
These findings suggest that TLR4-signaling activation, triggered by damage-associated molecular patterns, regulates the activation of the NLRP3 inflammasomes and is responsible for the function of the retina in retinal IR injury.
