RESUMEN

OBJECTIVES: To assess dysfunctional personality beliefs associated with specific personality disorders (PD), as well as psychopathological symptoms and psychological distress levels in central serous chorioretinopathy (CSC) patients. MATERIAL AND METHODS: This cross-sectional study included acute and chronic CSC patients and age- and sex-matched healthy volunteers. Dysfunctional personality beliefs and psychopathological symptoms assessed with Personality Belief Questionnaire-Short Form and Symptom Check List-90 Revised (SCL-90-R), respectively, were compared between CSC patients and healthy volunteers and between acute and chronic CSC patients. MAIN RESULTS: Of the 55 CSC patients included in the study analysis, 21 (38.2%) had acute and 34 (61.8%) chronic CSC. Avoidant PD (13.92±3.79 vs. 12.03±3.98, P=0.012) and obsessive-compulsive PD (13.94±3.95 vs. 12.27±3.75, P=0.025) scores on the PBQ-SF were significantly higher in CSC patients than in healthy volunteers. The PBQ-SF scores were similar between acute and chronic CSC patients. CSC patients scored significantly higher on the general severity index (GSI) and all symptom dimensions except phobic anxiety and psychoticism on the SCL-90-R. In addition, scores for obsessive-compulsive, depression, interpersonal sensitivity, paranoid ideation, and GSI were significantly higher in acute than in chronic CSC patients. CONCLUSIONS: This first study investigating the relationship between CSC and dysfunctional personality beliefs indicates that CSC patients have higher levels of dysfunctional beliefs related to avoidant and obsessive-compulsive PD than healthy volunteers. These findings present a new aspect of the personality profile of CSC patients and point to a target for intervention, i.e., dysfunctional beliefs, through a cognitive-psychiatric approach.

RESUMEN

We examined prevalence of mental health treatment utilization among 447 lesbian, gay, bisexual, transgender, and Two-Spirit (LGBTT-S) American Indian/Alaska Native (AI/AN) adults and the association of mental health treatment utilization with socio-demographic factors, social support, and mental health diagnoses. We derived data from the HONOR Project, a multi-site cross-sectional survey of Native LGBTT-S adults from seven U.S. metropolitan cities. Rates of lifetime mental health treatment utilization were higher for women (87%), those who were college educated (84%), and homeowners (92%). Cisgender women and transgender AI/AN adults had a higher prevalence than cisgender men of major depression, generalized anxiety, and panic disorder. Rates of subthreshold and threshold posttraumatic stress disorder were significantly higher for transgender adults. Lower positive social support and higher emotional social support were associated with greater odds of mental health treatment utilization. Mental health diagnoses and lifetime mental health treatment utilization was positively associated.

RESUMEN

BACKGROUND: Health systems are increasingly implementing remote telephone and Internet refill systems to enhance patient access to medication refills. Remote refill systems may provide an effective approach for improving medication non-adherence, but more research is needed among patients with limited English proficiency with poor access to remote refill systems. OBJECTIVE: To compare the use of remote medication refill systems among limited-English-proficiency (LEP) and English-proficient (EP) patients with chronic conditions. METHODS: Cross-sectional survey in six languages/dialects (English, Cantonese, Mandarin, Korean, Vietnamese, and Spanish) of 509 adults with diabetes, hypertension, or hyperlipidemia. Primary study outcomes were self-reported use of 1) Internet refills, 2) telephone refills, and 3) any remote refill system. LEP was measured by patient self-identification of a primary language other than English and a claims record of use of an interpreter. Other measures were age, gender, education, years in the U.S., insurance, health status, chronic conditions, and number of prescribed medications. Analyses included multivariable logistic regression weighted for survey non-response. RESULTS: Overall, 33.1 % of patients refilled their medications by telephone and 31.6 % by Internet. Among LEP patients (n = 328), 31.5 % refilled by telephone and 21.2 % by Internet, compared with 36.7 % by telephone and 52.7 % by Internet among EP patients (n = 181). Internet refill by language groups were as follows: English (52.7 %), Cantonese (34.9 %), Mandarin (17.4 %), Korean (16.7 %), Vietnamese (24.4 %), and Spanish (12.6 %). Compared to EP patients, LEP patients had lower use of any remote refill system (adjusted odds ratio [AOR] 0.18; p < 0.001), CONCLUSIONS: LEP patients are significantly less likely than EP patients to use any remote medication refill system. Increased reliance on current systems for remote medication refills may increase disparities in health outcomes affecting LEP patients with poor access to telephone and Internet medication refills.

RESUMEN

BACKGROUND: In twin pregnancies, the rates of adverse perinatal outcome and subsequent long-term morbidity are substantial, and mainly result from preterm birth (PTB). OBJECTIVES: To assess the effectiveness of progestogen treatment in the prevention of neonatal morbidity or PTB in twin pregnancies using individual participant data meta-analysis (IPDMA). SEARCH STRATEGY: We searched international scientific databases, trial registration websites, and references of identified articles. SELECTION CRITERIA: Randomised clinical trials (RCTs) of 17-hydroxyprogesterone caproate (17Pc) or vaginally administered natural progesterone, compared with placebo or no treatment. DATA COLLECTION AND ANALYSIS: Investigators of identified RCTs were asked to share their IPD. The primary outcome was a composite of perinatal mortality and severe neonatal morbidity. Prespecified subgroup analyses were performed for chorionicity, cervical length, and prior spontaneous PTB. MAIN RESULTS: Thirteen trials included 3768 women and their 7536 babies. Neither 17Pc nor vaginal progesterone reduced the incidence of adverse perinatal outcome (17Pc relative risk, RR 1.1; 95% confidence interval, 95% CI 0.97-1.4, vaginal progesterone RR 0.97; 95% CI 0.77-1.2). In a subgroup of women with a cervical length of ≤25 mm, vaginal progesterone reduced adverse perinatal outcome when cervical length was measured at randomisation (15/56 versus 22/60; RR 0.57; 95% CI 0.47-0.70) or before 24 weeks of gestation (14/52 versus 21/56; RR 0.56; 95% CI 0.42-0.75). AUTHOR'S CONCLUSIONS: In unselected women with an uncomplicated twin gestation, treatment with progestogens (intramuscular 17Pc or vaginal natural progesterone) does not improve perinatal outcome. Vaginal progesterone may be effective in the reduction of adverse perinatal outcome in women with a cervical length of ≤25 mm; however, further research is warranted to confirm this finding.

RESUMEN

Behçet's disease (BD) is a chronic inflammatory autoimmune disease. Although raised levels of proinflammatory cytokines in BD have been reported, the pathogenesis is still unknown. The aim of this study was to investigate the association of NFKB1 and NFKBIA polymorphisms and their single and combined analysis effects on susceptibility of BD in Turkish population. We analysed the distribution of NFKB1 -94 ins/del ATTG (rs28362491) and NFKBIA 3' UTR A→G (rs696) polymorphisms using PCR-RFLP method in 89 patients with BD and 190 controls in this population. Statistical analysis of the results was performed by calculating OR, and 95% CI via χ(2) test and using Bonferroni correction. According to the significant results of both single and combined genotype analysis, the frequencies of ins/ins genotype and ins allele of rs28362491 were significantly higher in patients with BD (Pc = 0.003, 0.004, respectively). Also, higher frequencies of the rs696 variant containing AA genotype was found in patients with BD (Pc = 0.0033), whereas no statistical significant differences in distribution of the alleles of rs696 polymorphism in patients and controls. In addition, according to the combined genotype analysis, the wild type of both rs28362491 and rs696 polymorphisms (ins/ins/AA genotype) was also significantly higher in BD cases (Pc = 0.044). Our findings prove that both single and combined genotype analysis of rs28362491 and rs696 polymorphisms indicate that the wild genotypes of both two SNPs (ins/ins and AA genotypes) and ins/ins/AA combined genotype are strongly associated with enhanced risk of BD in a Turkish population.

RESUMEN

PURPOSE: To investigate the diagnostic accuracy of endometrial curettage in patients with endometrial carcinoma. In this retrospective study, pre- and postoperative histopathologic findings of patients with endometrial cancer were investigated. METHODS: 168 patients with the final diagnosis of endometrial cancer were enrolled in the study. Pre- and postoperative histopathologic diagnoses and grades (according to the 1988 FIGO classification) of the patients were compared retrospectively. RESULTS: 22 patients were diagnosed as having endometrial hyperplasia and the remaining 136 patients had endometrial carcinoma preoperatively. Overall discrepancy rate of grades was 39% (31% upgrade, 8% downgrade; p < 0.05). There was also 9% discrepancy between the pre- and postoperative histopathological types. CONCLUSION: It has been suggested that since endometrial cancer patients with low grades according to the preoperative pathologic diagnosis have a potential to upgrade, the management of these patients if myometrial invasion is less than one-half thickness, simply by hysterectomy plus bilateral salpingo-oophorectomy (without lymph node sampling), might actually miss some patients who actually deserve surgical staging. Further studies are needed to draw a sufficient conclusion.

RESUMEN

This study has examined the effects of type of dairy product (whole milk, skim milk, heavy cream) and chocolate matrix (baking, dark, dairy milk, white) on the oral absorption of the chocolate flavanols (+)-catechin and (-)-epicatechin in a small animal model. In the study, each flavanol compound, as a solution in water or a dairy product or as a chocolate dispersion in water, was administered intragastrically to male Sprague-Dawley rats in an amount equal to or equivalent to 350 mg/kg. In each instance, blood samples were collected over a 5 h period, and used to measure plasma total catechin concentrations by HPLC after enzymatic hydrolysis of flavanol conjugates. Pharmacokinetic data were evaluated using a one compartment approach. Whole milk and heavy cream, and to a much lesser extent skim milk, lowered the oral absorption of both (+)-catechin and (-)-epicatechin and altered the AUC, C(max), k(a), k(e) and t1/2 values in direct proportion to their fat, but not to their protein, content. In addition, the t(max) for solutions of (-)-epicatechin in water and skim milk occurred 2 h earlier than from solutions in whole milk and heavy cream. Similarly, dispersions of baking chocolate in water and in whole milk yielded plasma levels of monomeric catechins that were, respectively, about equal to and much lower than those from aqueous solutions of authentic flavanols. A determining role for a chocolate matrix (dark, dairy milk or white chocolate) on the oral absorption of its constitutive monomeric flavanols was suggested by the apparent variability in plasma total catechins levels that existed among them both before and after their spiking with equal amounts of exogenous (+)-catechin and (-)-epicatechin. Such a variability could reflect differences among different chocolates in terms of their physical properties, matrix components, and matrix characteristics imposed by the manufacturing process used for each type of chocolate. In all the experiments, (+)-catechin demonstrated a higher oral absorption than (-)-epicatechin.

RESUMEN

This study has investigated the micellar properties of the d-alpha-tocopheryl polyethylene glycol succinate esters 400 (TPGS 400) and 1000 (TPGS 1000) in terms of critical micellar concentration (CMC), apparent aggregation number (N(agg)), microviscosity and micropolarity using steady state fluorescence techniques and fluorescent probes. In addition it has compared these properties against those of a Triton-type surfactant such as Triton X-100. The CMC values for TPGS 400, TPGS 1000 and Triton X-100 were 1.51 mM, 0.02 mM and 0.19 mM, respectively. The N(agg) values for TPGS 1000 and Triton X-100 were, respectively, 10 and 63. Due to the cloudiness of its aqueous solutions, no attempt was made to evaluate the microviscosity and to obtain the N(agg) for TPGS 400. Microviscosity at the probe site for all three surfactants was high and rather similar in spite of differences among their CMC values. The ability of TPGS 400 and TPGS 1000 to provide an environment for the fluorescence quenching of micelle-solubilized pyrene appears to be associated with their hydrophobic aromatic domains. To our knowledge the present study is the first attempt at systematically studying the micellar properties of the two most widely used TPGS compounds and of comparing these properties against each other and against those of an established nonionic surfactant.

RESUMEN

Primary cancer of the vagina constitutes 1-2% of all malignant genital tract tumors in women. As one of the most complicated therapeutic problems in gynecological oncology, this disease had been deemed to be untreatable until the end of 1930s. Presently, as a result of technological improvements in radiotherapy and radical surgery, more favorable prognoses are known to be achieved even in advanced cases. In the present case, a woman with vaginal cancer and Stage IV massive uterovaginal prolapsus, which could not be repositioned under general anesthesia, was repositioned by surgical intervention prior to radiotherapy to avoid any potential vesicovaginal fistula formation. The cervix was bilaterally suspended to the pectineal ligaments by polypropylene mesh.

RESUMEN

Letrozole was compared with clomiphene citrate (CC) as a first-line treatment for ovulation induction in women with polycystic ovaries (PCOs). A total of 106 women with primary infertility and a diagnosis of PCOs were randomized to receive either 100 mg CC (n = 55) or 2.5 mg letrozole (n = 51) daily for 5 days. Human chorionic gonadotrophin (hCG) at a dose of 10000 IU was administered when at least one follicle with a mean diameter > or = 18 mm was observed using transvaginal ultrasound. The number of mature follicles was significantly lower, but endometrial thickness and ovulation and pregnancy rates were significantly higher in the letrozole group than in the CC group. In conclusion, letrozole is associated with a higher pregnancy rate than CC in PCO patients and may have a role as a first-line treatment for anovulatory patients with PCOs.

RESUMEN

OBJECTIVE: Because most risk factors for melanoma are immutable constitutional factors such as skin type, it is important to more fully understand the relationship between melanoma risk and sun exposure, one of the few modifiable risk factors for the disease. The goal of this case-control study was to quantify the risks of melanoma associated with UV exposure at different periods of life. METHODS: Cases were 386 patients between the ages of 35 and 74 who were diagnosed with primary cutaneous melanoma within the Seattle-Puget Sound area during 1997. Controls were 727 participants of the same age and geographic area, selected by random-digit dialing. A telephone interview included a complete residential history, lifetime sun exposure history (days in the summer sun for at least 4 h at each place of residence), and personal characteristics. UV exposure was calculated based on satellite data on potential erythemal exposure at each place of residence, years at each location and time spent in the sun at each location. Logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (CI) reflecting the risk of melanoma associated with UV exposure, after adjustment for age, sex, income, tendency to burn and sunburns during ages 2-10. RESULTS: Among women, lifetime UV exposure was associated with melanoma risk (adjusted OR = 1.99 for highest versus lowest quartile, 95% CI: 0.95-3.03, p for trend = 0.008). There were significant trends for UV exposure during ages 1-10, 11-20 and 31-40 (all p < 0.02). Among men, there were no significant associations at any time period, but lifetime UV exposure was associated with higher risk for men who had a tendency toward severe or painful sunburns (OR = 2.85 for highest versus lowest quartile, 95% CI: 0.84-9.64, p for trend = 0.04). CONCLUSION: The differing results by sex are not easily interpretable, though it may be useful to target those with a higher sensitivity to the sun when formulating messages for prevention of melanoma by lowering exposure to UV.

RESUMEN

OBJECTIVE: To examine associations of diet with acculturation among Hispanic immigrants from Mexico to Washington state and to compare dietary patterns of Hispanic with non-Hispanic white residents. DESIGN: Data are part of the baseline assessment for a community-randomized cancer prevention trial. The Fat-Related Diet Habits questionnaire and the National 5-A-Day for Better Health program dietary assessment instruments were used to collect data on fat and fruit and vegetable intake, respectively. Data were also collected on demographic characteristics and acculturation status. SUBJECTS/SETTING: A total of 1,689 adult Hispanic and non-Hispanic white residents of 20 communities in the Yakima Valley, WA, completed in-person interviews. STATISTICAL ANALYSES PERFORMED: Mixed model regression analyses tested associations of acculturation with diet. These models compared the fat and the fruit and vegetable intake of Hispanics vs non-Hispanic white residents. Additional analyses compared the diets of highly acculturated Hispanics with low-acculturated Hispanics. All models included age, sex, income, and education and were also adjusted for the random effect of community. RESULTS: Dietary patterns varied by ethnicity and acculturation status. On average, compared with non-Hispanic white residents, Hispanics consumed one more serving of fruits and vegetables per day (P<.001). Dietary habits changed as Hispanics acculturated to the United States. Highly acculturated Hispanics ate fewer servings of fruits and vegetables per day compared with those not highly acculturated (P<.05). Highly acculturated Hispanics had slightly higher, but not statistically significant, scores on the Fat-Related Diet Habits questionnaire, which corresponds to a higher fat intake, compared with low-acculturated Hispanics. The early dietary changes made on acculturation included adding fat at the table to breads and potatoes. APPLICATIONS/CONCLUSIONS: Nutrition professionals should encourage their Hispanic clients to maintain their traditional dietary practices, such as a high intake of fruits and vegetables and eating bread and potatoes without added fat.

RESUMEN

Farmworkers are exposed to pesticides and may take home pesticide residues to their families. In this paper, self-reported pesticide exposure and home practices to reduce the amount of pesticide residues taken home were examined among 571 farmworkers. Urine samples from a subsample of farmworkers and children and dust samples from households and vehicles also assessed pesticide exposure. Overall, 96% of respondents reported exposure to pesticides at work. Many employers did not provide resources for hand washing. Farmworkers' protective practices to keep pesticide residues out of the home were at a low level. In a subset of respondents, pesticide levels above the limit of quantitation were seen in the urine of children and adults and in house and vehicle dust. The results support the take-home pathway of pesticide exposure. Ways must be found to reduce this pesticide exposure among children of farmworkers.

RESUMEN

OBJECTIVES: Socioeconomic status is explored as a predictor of differences between Hispanics and non-Hispanic Whites in cancer prevention behavior. METHODS: In a cross-sectional study, in-person interviews (n = 1795) were conducted in a population-based random sample of adults in 20 communities with a high proportion of Hispanics. RESULTS: Hispanics were significantly less likely than non-Hispanic Whites to ever have had cervical (p < 0.001), breast (p = 0.007), or colorectal cancer (FOBT p = 0.008; sigmoidoscopy/colonoscopy p < 0.002) screening. After adjusting for socioeconomic status (education and having health insurance), only differences in cervical cancer remained significant (p = 0.024). After adjusting for socioeconomic status, Hispanics had a significantly higher intake of fruits and vegetables per day (4.84 servings) than non-Hispanic Whites (3.84 servings) (p < 0.001); and fat behavior score was marginally significant after adjustment for socioeconomic status (p = 0.053). Significantly fewer Hispanics were current smokers than non-Hispanic Whites (p < 0.001). CONCLUSIONS: There is only limited support for the hypothesis that socioeconomic status is a major determinant of some cancer-related behaviors; specifically, socioeconomic status is related to mammography and colorectal screening, but not cervical cancer, dietary behavior, or smoking.

RESUMEN

A rapid, specific and accurate proton nuclear magnetic resonance (1H NMR) spectroscopic method was developed for the simultaneous quantitative analysis of propantheline bromide and its degradation product, xanthanoic acid, in bulk materials and tablets. 1,3,5-Trinitrobenzene served as an internal standard and deuterochloroform was used as the solvent for the analytical samples. The quantities of propantheline bromide and xanthanoic acid were calculated on the basis of the integrals for signals of the methine proton of propantheline at 5.09 ppm, the methine proton of xanthanoic acid at 4.99 ppm, and the aromatic protons of the internal standard at 9.39 ppm. The accuracy of the method was established through the analysis of synthetic mixtures containing the parent compound, its degradation product and the internal standard. An excellent agreement was verified between the assay results and the quantities of the various compounds in the mixtures. The mean +/- SD recovery values for propantheline bromide and xanthanoic acid from a set of 10 synthetic mixtures were 99.6 +/- 0.8% and 98.9 +/- 1.8%, respectively. The assay of 10 lots of commercial propantheline bromide tablets by 1H NMR spectroscopy indicated drug and degradate contents in the ranges 97.1-99.8% and 0.1-0.9%, respectively. In addition, the proposed analytical method was found suitable for detecting the formation of xanthanoic acid from propantheline bromide in aqueous media in concentrations below 0.1% of that of the parent compound.

RESUMEN

A proton nuclear magnetic resonance (PMR) spectroscopic method is described for the direct assay and identification of the triiodinated radiographic contrast agents iopamidol (nonionic type) and iothalamate meglumine (ionic type) in commercial solutions and as a bulk material. Samples were prepared by simply diluting an injectable solution with or dissolving a powdered sample in D2O. Sodium acetate was added to serve as an internal standard. Quantitations were based on the resonance signals for the protons of the CH3-CO-group at 1.58 ppm (iopamidol) or 2.25 ppm (iothalamate), CH3-N-group at 2.38 ppm (meglumine) and CH3-CO-group at 1.92 ppm (acetate). The mean +/- SD (n = sets of 10 samples each) recovery of iopamidol, iothalamic acid and meglumine from synthetic mixtures with the internal standard were 99.6 +/- 0.63, 99.7 +/- 0.66 and 99.9 +/- 1.18%, respectively; with the values ranging from 98.7-100.9% for iopamidol and iothalamate, and from 98.3-100.8% for meglumine.

RESUMEN

The effects of cis-9-octadecenoic acid (oleic acid) and of a group of chemically related cis- (ricinoleic acid) and trans- (ricinelaidic acid) 12-monohydroxylated derivatives and their corresponding ethyl and methyl esters on the skin permeation of model hydrophobic (hydrocortisone, log K=1.61) and hydrophilic (5-fluorouracil, log K=-0.89) drugs was investigated in vitro using excised hairless mouse skin. Drug solutions were prepared in propylene glycol, with and without the addition of a fatty acid to a level of 5%. Whereas the addition of oleic acid markedly enhanced the transdermal flux of both drugs relative to a sample in propylene glycol alone (hydrocortisone approximately 1800-fold; 5-fluorouracil approximately 330-fold), that of a cis- or trans-12-monohydroxylated analog of oleic acid resulted in only a small increase (1.4-2.7-fold for hydrocortisone; 4.4-6.6-fold for 5-fluorouracil). On the other hand, the methyl and ethyl esters of cis- and trans-12-hydroxy-9-octadecenoic acid exerted a much greater enhancing effect (327-720-fold for hydrocortisone, 42-74-fold for 5-fluorouracil) than the corresponding parent fatty acids. Furthermore, whereas the ethyl esters were found to have a greater effect on the skin permeation of hydrocortisone than the methyl esters, the reverse was true with regards to 5-fluorouracil. Additionally, the esters of trans-12-hydroxy-9-octadecenoic acid promoted permeation to an extent comparable to that achieved with their cis-counterparts.
