Context: Two years ago the authors began to use Swan-Ganz catheters to generate more complex hemodynamic data as a better guide to resuscitation of burns. This study uses the information to identify differences between survivors and nonsurvivors.', 'Fifty-three consecutive patients with major burns were treated using Swan-Ganz-generated data. Additional information was collected, including demographics, intake and output, medications, and arterial blood gas (including calculated oxygen consumption). Statistical analysis incorporated adjustments for autocorrelation.', 'The patients included 38 men and 15 women, averaged 43.7 years of age, and had a mean burn size of 40%. Thirteen patients suffered severe inhalation injury. Data collected hourly over 3 days were collapsed across 6-hour observation periods. Mean values, when plotted across time, discriminated the 37 survivors from the 16 nonsurvivors. Poor response to resuscitation as evidenced by increased use of colloid fluid and cardiotonic drugs plus failure to maximize oxygen consumption were associated with nonsurvival.
Answer: Unsustained or inadequate response to hyperdynamic resuscitation of burns was associated with nonsurvival.

Ex Output:
Do survival in major burn injuries is predicted by early response to Swan-Ganz-guided resuscitation?

Context: Brassica napus (AACC) is self-compatible, although its ancestor species Brassica rapa (AA) and Brassica oleracea (CC) are self-incompatible. Most B.napus accessions have dominant self-compatibility (SC) resulting from an insertion of 3.6 kb in the promoter region of BnSCR-1 on the A genome, while recessive SC in B.napus has rarely been observed. Expression and cloning of SRK and SCR genes and genetic analysis were carried out to dissect bases of recessive SC in B.napus.', 'Eleven accessions were screened to identify stable recessive SC and had the S genotype BnS-7 on the A genome and BnS-6 on the C genome similarly to BrS-29 and BoS-15, respectively. In eight SC accessions, BnSCR-7 and BnSCR-6 were nearly undetectable and harbored no structural mutations in the promoters, while SRK genes were expressed at normal levels and contained intact CDS, with the exception of BnSRK-7 in line C32. SRK and SCR genes were expressed normally but their CDSs had no mutations in three SC accessions. In self-incompatible S-1300 and 11 F1 hybrids, SRK genes and BnSCR-1300 transcripts were present at high levels, while expression of the BnSCR-7 and BnSCR-6 were absent. Plants of S genotype S1300S1300 were completely SI, while SI phenotypes of SBnS-7SBnS-7 and S1300SBnS-7 plants were segregated in BC1 and F2 populations.
Answer: The recessive SC in eight accessions is caused by the loss of function of BnSCR-7 and BnSCR-6 in pollen. Translational repression contributes to the recessive SC in three accessions, whose SRK and SCR genes were expressed normally and had identical CDSs to BrS-29 or BoS-15. SI in 11 F1 hybrids relies on the expression of BnSCR-1300 rather than SRK genes. Other factor(s) independent of the S locus are involved in recessive SC. Therefore, diverse causes underlie recessive SC in B. napus, yielding insight into these complex mechanisms.

Do gene expression and genetic analysis reveal diverse causes of recessive self-compatibility in Brassica napus L?

Context: Although obesity is associated with gonadal dysfunction in the general population, gonadotoxic treatment might diminish the impact of obesity in childhood cancer survivors (CCS). The aim was to evaluate whether altered body composition is associated with gonadal dysfunction in male CCS, independent of gonadotoxic cancer treatment.', 'Three hundred fifty-one male CCS were included. Median age at diagnosis was 5.9 years (0-17.8) and median age at follow-up 25.6 years (18.0-45.8). Total and non-SHBG-bound testosterone, sex hormone-binding globulin, inhibin B, and follicle-stimulating hormone (FSH) were studied. Potential determinants were BMI, waist circumference, waist-hip ratio, and body composition measures (dual energy X-ray absorptiometry).', 'Non-SHBG-bound testosterone was significantly decreased in survivors with BMI 30 kg/m(2) (adjusted mean 9.1 nmol/L vs. 10.2 nmol/L, P = 0.015), high fat percentage (10.0 vs. 11.2, P = 0.004), and high waist circumference (>102 cm) (9.0 vs. 11.0, P = 0.020). Survivors with high fat percentage (25%) had significantly lower inhibin B/FSH ratios (inhibin B/FSH ratio: -34%, P = 0.041).
Answer: Obesity is associated with gonadal dysfunction in male CCS, independent of the irreversible effect of previous cancer treatment. Randomized controlled trials are required to evaluate whether weight normalization could improve gonadal function, especially in obese survivors with potential other mechanisms than lifestyle causing their obesity.

Ex Output:
Does obesity independently influence gonadal function in very long-term adult male survivors of childhood cancer?
