Given a passage with a context and an answer, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Question: Context: To describe the prevalence and correlates of hazardous drinking among female sex workers (FSWs) at 13 sites throughout Mexico.', 'FSWs (N = 1089) who were enrolled in a brief sexual risk reduction intervention (Mujer Segura) were queried about their sexual risk and substance use practices and their work contexts. Participants were classified as hazardous or non-hazardous drinkers based on the Alcohol Use Disorders test (AUDIT-C). Logistic regression models were used to examine individual, contextual, and community-level factors as correlates of hazardous drinking.', 'Ninety-two percent of participants reported alcohol consumption in the past month. Among drinkers (N = 1001), 83% met AUDIT-C criteria for hazardous drinking. Factors that were independently associated with hazardous drinking included: drug use in the past month (adjusted odds ratio (AOR) = 3.31; 95% CI 1.29-8.45), being a cigarette smoker (AOR = 1.71; 95% CI 1.13-2.58), being a barmaid or dance hostess (AOR = 3.40; 95% CI 1.95-5.91), alcohol use before or during sex with clients (AOR = 7.78; 95% CI 4.84-12.52), and working in a city with a higher marginalization index (AOR = 1.07; 95% CI 1.04-1.11).
Answer: Findings support the high prioritization by public health authorities of alcohol prevention and treatment programs for FSWs.

Answer: Does prevalence and correlate of Hazardous Drinking among Female Sex Workers in 13 Mexican Cities?


Question: Context: Many bacterial meningitis patients experience neurological or neuropsychological sequelae, predominantly deficits in short-term memory, learning, and attention. Neuropsychological symptoms after viral meningitis are observed less frequently. Sleep disturbance has been reported after both viral and bacterial meningitis.', 'To examine systematically the frequency and extent of sleep disturbance in meningitis patients.', 'Eighty six viral or bacterial meningitis (onset of acute disease at least 1 year previously) patients were examined using two standardised questionnaires (Schlaffragebogen B and the Pittsburgh Sleep Quality Index, PSQI) in conjunction with a standardised neurological examination, and compared to a control group of 42 healthy age-matched volunteers.', 'Patients after both viral and bacterial meningitis described their sleep as reduced in quality and less restful than that of healthy control subjects; both patient groups had a pathological mean PSQI total score. Impaired sleep scores after meningitis were not correlated to either the Glasgow Coma Scale or the Glasgow Outcome Scale. Moreover, no relationship between residual neurological dysfunction or depressivity and sleep quality was observed.
Answer: Impaired sleep is a long-term consequence of meningitis. Additional, so far undetermined, factors other than the severity of concomitant neurological deficits are responsible for the development of this sequela.

Answer: Are sleep disorders long-term sequelae of both bacterial and viral meningitis?


Question: Context: To demonstrate a method to extract the meaningful biologic information from (111)In-radiolabeled capromab pendetide (ProstaScint) SPECT scans for use in radiation therapy treatment planning by removing that component of the (111)In SPECT images associated with normal structures.', 'We examined 20 of more than 80 patients who underwent simultaneous (99m)Tc/(111)In SPECT scans, which were subsequently registered to the corresponding CT/MRI scans.A thresholding algorithm was used to identify (99m)Tc uptake associated with blood vessels and CT electron density associated with bone marrow. Corresponding voxels were removed from the (111)In image set.', 'No single threshold value was found to be associated with the (99m)Tc uptake that corresponded to the blood vessels. Intensity values were normalized to a global maximum and, as such, were dependent upon the quantity of (99m)Tc pooled in the bladder. The reduced ProstaScint volume sets were segmented by use of a thresholding feature of the planning system and superimposed on the CT/MRI scans.
Answer: ProstaScint images are now closer to becoming a biologically and therapeutically useful and accurate image set. After known sources of normal intensity are stripped away, the remaining areas that demonstrate uptake may be segmented and superimposed on the treatment-planning CT/MRI volume.

Answer:
Does procedure for unmasking localization information from ProstaScint scan for prostate radiation therapy treatment planning?
