Context: Interferon regulatory factor 5 is a transcription factor involved in type I interferon (IFN) secretion. This study was undertaken to investigate whether a 5-bp (CGGGG insertion/deletion) promoter polymorphism is involved in genetic predisposition to primary Sjögren's syndrome (SS) and to assess the functional consequences of this polymorphism.", 'The exploratory cohort consisted of 185 patients with primary SS and 157 healthy controls, and the replication cohort consisted of 200 patients with primary SS and 282 healthy controls. Levels of IRF5 messenger RNA (mRNA) were assessed at baseline and after in vitro infection with reovirus in peripheral blood mononuclear cells (PBMCs) from 30 patients with primary SS and from salivary gland epithelial cells that had been cultured for 4 weeks from patients with primary SS or sicca symptoms.', 'Carriage of the IRF5 4R CGGGG allele was associated with a greatly increased risk of primary SS in both cohorts (odds ratio 2.00 [95% confidence interval 1.5-2.7], P = 6.6 x 10(-6)). The CGGGG insertion/deletion polymorphism alone was sufficient to explain the association of primary SS with IRF5. The level of IRF5 mRNA in PBMCs depended significantly on genotype (P = 0.002) and was correlated with the levels of mRNA for the IFN-induced genes MX1 and IFITM1. Cultured salivary gland epithelial cells from patients carrying the 4R CGGGG IRF5 allele showed a high level of IRF5 mRNA (P = 0.04), which was amplified after reovirus infection (P = 0.026).
Answer: Our findings indicate an association of the CGGGG insertion/deletion polymorphism of the IRF5 promoter with primary SS. Patients carrying the 4R CGGGG IRF5 allele had a high level of mRNA for IRF5 in PBMCs and salivary gland epithelial cells, mainly after in vitro viral infection. Patients with high levels of mRNA for IRF5 also had high levels of mRNA for type I IFN-induced genes in PBMCs.
Is the CGGGG insertion/deletion polymorphism of the IRF5 promoter a strong risk factor for primary Sjögren 's syndrome?

Context: The necessity for general anesthesia represents an impediment to using a laparoscopic approach for some procedures that are otherwise performed with the patient under local anesthesia using a conventional open technique. Heating and humidifying the insufflation gas reportedly reduces perioperative pain associated with a CO2 pneumoperitoneum, thus enabling awake laparoscopy.', 'Two cases are reported herein of laparoscopy performed with the patient under local anesthesia using heated, humidified CO2 gas for the pneumoperitoneum.', 'Both patients experienced pain with insufflation of heated, humidified CO2 gas of sufficient magnitude that the procedure could not be performed. The CO2 gas was washed out and replaced with helium gas insufflation with complete resolution of pain. The laparoscopic procedures were accomplished without further discomfort with local anesthesia and using a helium gas pneumoperitoneum.
Answer: Heated, humidified CO2 gas insufflation does not reduce pain sufficiently to permit satisfactory performance of laparoscopy with local anesthesia, especially when full volume insufflation is required. Cold, dry helium gas produces no pain. The theory that cold, dry insufflation gas is a source of peritoneal pain during laparoscopy needs to be reassessed.
Is heated , humidified CO2 gas unsatisfactory for awake laparoscopy?

Context: Linoleic 18:2 (n-6) and alpha-linolenic 18:3 (n-3) essential fatty acids and long-chain polyunsaturated fatty acids (LC-PUFA) are essential nutrients for growth and neonatal development. Consumption of preformed n-3 LC-PUFA has been shown to increase gestational duration and to decrease the incidence of premature birth in human studies. This study evaluated the association of essential fatty acids and LC-PUFA in breast milk on the growth of premature children (weight, height and head circumference).', 'Thirty-seven premature infants with a gestational age of 37 weeks or less were followed until 6 months of gestational age, adjusted for prematurity. The milk from mothers, weight, height and head circumference measures of children were collected during the follow up. The breast milk fatty acids were quantified by gas-liquid chromatography.', 'Our results showed that total n-3 PUFA was positively associated with weight gain (p = 0.05), height (p = 0.04) and body mass index (BMI) of children (p = 0.05). Our results also indicate that both linoleic acid and total essential fatty acids were positively associated with BMI and head circumference, whereas oleic acid was positively associated only with head circumference.
Answer: These results suggest that the n-3 PUFA composition of milk may be associated with weight gain and growth. Considering the advantages of n-3 LC-PUFA consumption on infant growth and visual function and its association with reduced incidence of premature birth, dietitians should advise pregnant women to increase their intake of foods high in n-3 LC-PUFA.

Is n-3 polyunsaturated fatty acids in milk associate to weight gain and growth in premature infants?
