instruction:
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.
question:
Context: This study examines the prevalence and correlates of self-reported premenstrual symptoms among a large, population-based sample of reproductive age, active-duty women.', 'Data were obtained from a combined dataset of two large-scale mail surveys designed to represent the total force. Subjects included in the present study were 6026 active-duty women of all branches of military service stratified by service, paygrade group, race/ethnicity, and location. A multivariate approach is used to evaluate the interrelationships among psychosocial and lifestyle correlates of premenstrual symptoms or pain after controlling for demographic differences in women who reported premenstrual symptoms or pain during the past 3 months (cases) and those who did not (controls).', 'Premenstrual symptoms were reported by nearly 2 of every 3 reproductive age women. Women reporting premenstrual symptoms were more likely to report other symptoms of menstrual dysfunction, two or more current medical conditions, migraines, and healthcare provider visits in the past year. After controlling for the protective effects of taking Depo-Provera (Upjohn, Kalamazoo, MI) and ever being pregnant, younger age, trying to lose weight, heavier drinking, poorer self-perceived health, and overall job stress were the most significant predictors of premenstrual symptoms. The greatest risk factor was a high level of job stress, with an almost 3-fold increase in risk relative to those without symptoms.\Question: Does psychosocial and lifestyle correlate of premenstrual symptoms among military women?
answer:
Work stress may mediate the relationship among depression and premenstrual symptoms. Further research is needed to elucidate the biological interrelationships among work stress, hormonal function, and premenstrual symptomatology.


question:
Context: The basis of the treatment of painful diabetic neuropathy is the use of drugs that block the transmission of pain (antineuritics) and a good metabolic control of underlying disease.', 'To describe the outcomes of 17 type-2 diabetics with painful neuropathy, treated between 1988 and 2005 with symptomatic therapy plus intensified insulin.', 'Review of medical records of 17 type-2 diabetic patients, aged 63+/-11 years and a duration of diabetes of 15+/-8 years. All patients received intensified insulin therapy with 0.35 units/kg of NPH insulin (2/3 before breakfast and 1/3 evening meal), plus capillary glucose measurements and regular insulin (with sliding-scale centered in approximately 0.1 units/kg) before the 3 main meals. All patients were also treated with gabapentin, nortriptyline or clomipramine. Pain was assessed using a visual analog score of 10 points.', 'After 1 year, glycosilated hemoglobin decreased from 10.0+/-1.4% to 7.7+/-1.2% (p approximately =0.003). Pain decreased from 10 to 5.1+/-3.3 at one month, 2.3+/-3.2 at six months, and 3.1+/-3.6 at 1 year (p <0.01). There was a direct statistical correlation between the reduction of HbA1C and pain decline (r =0.736; p =0.037). Pain scores were lower than those reported elsewhere for Pregabalin (n =76; p =0.05), Lamotrigine (n =27; p <0.0005), Topiramate (n =208; p <0.005), and Gabapentin (n =84; p <0.025). The lack of difference to Sodium Valproate (n =21; p =0.07) had borderline significance.\Question: Is [ Intensified insulin therapy plus antineuritic medication more effective than antineuritics alone in painful diabetic neuropathy ]?
answer:
The addition of intensified insulin therapy to the symptomatic treatment of painful neuropathy in type-2 diabetics, significantly enhanced the reduction of pain. The lowering of glycosilated hemoglobin was a significant predictor of success in pain reduction.


question:
Context: PRV-1 mRNA is overexpressed by neutrophils from polycythemia vera patients and is homologous to NB1 a gene overexpressed in reactive neutrophilia.', 'These investigations were designed to confirm searches of genome databases suggesting that PRV-1 and NB1 are alleles of the same gene, CD177, and confirm a pseudogene adjacent to CD177. Methods included polymerase chain reaction (PCR), cloning, sequencing, and fluorescent hybridization studies.', 'The coding region of PRV-1 was PCR-amplified from human fetal RNA, cloned, and used to screen the RPCI-11 bacterial artificial chromosome (BAC) library. Five BACs were reactive with the PRV-1 probe. PCR analysis of the BACs with primers encompassing PRV-1 exons, containing four known single-nucleotide polymorphisms, followed by sequencing rendered amplicons identical to PRV-1 in all five BACs. Analysis of all five by restriction digestion yielded fragments possible only if both the gene and the pseudogene are present. End sequencing of the BACs localized them to the same chromosome region. G-banding and fluorescence in situ hybridization at the 400- and 850-band levels of resolution mapped one BAC to chromosome band 19q13.2 and sublocalized the BAC to band 19q13.31, respectively.\Question: Are the gene overexpressed in polycythemia rubra vera , PRV-1 , and the gene encoding a neutrophil alloantigen , NB1 , alleles of a single gene , CD177 , in chromosome band 19q13.31?
answer:

PRV-1 and NB1 are alleles of the same gene now referred to as CD177. Changes in CD177 expression may be a marker of increased or decreased myelopoiesis and are therefore an effect of, rather than a cause of, myeloproliferative disorders.
