Effect of small doses of aspirin and acetaminophen on total menstrual loss and pain of cramps and headache

90 women participated in a 4-month study. During the first 2 periods, they took no pain relievers whatsoever; during their last 2 periods they took 2 X 325 mg aspirin, acetaminophen or an identically packaged placebo every 4 h to total 8 tablets during the first 24 h of their periods beginning with spotting. For statistical analysis, periods 1 and 2 were combined and averaged, then compared with periods 3 and 4 combined and averaged. Total menstrual loss in grams, number of days of flow, and pain of cramps and headaches were analyzed by MANOVA for each of the three treatment groups. An ANOVA for each of these variables as well as for daily menstrual loss for the first 3 menstrual days was also performed. The MANOVA for all variables by the three treatment groups failed to show any significant differences. Similarly, ANOVAs for the individual variables failed to indicate significant differences except for the variable pain of cramps (p = 0.0072). The Duncan's Multiple Range Test for pain of cramps showed that the average pain for the placebo group was higher than for either the aspirin or the acetaminophen group, although the means for these two groups were not significantly different. These results indicate that neither aspirin nor acetaminophen in the doses given alter either total menstrual loss or the pattern of loss during the first 3 menstrual days. However, both preparations were found to be more effective than placebo in reducing pain of cramps.     

Parathyroid hormone is not required for normal milk composition or secretion or lactation-associated bone loss in normocalcemic rats

To determine if parathyroid hormone (PTH) is essential for lactation in rats, the parathyroid glands were removed surgically during the first week of lactation and the rats were given a diet containing a high calcium-phosphorus ratio to maintain a normal serum calcium concentration. Lactating rats were placed on diet containing 1.2% calcium (Ca) and 0.8, 0.6, or 0.4% phosphorus (P) on day 2 postpartum (PP) and were parathyroidectomized (PTX) at 4-6 days PP. At 10 days PP serum Ca was 10.5 +/- 0.2 mg/dl (mean +/- SEM) for PTX rats and 10.4 +/- 0.3 mg/dl in sham-operated lactating rats when the diet contained 0.6% P. When the diet P was 0.8%, the litters gained little or no weight and serum Ca fell to 6.9 +/- 0.6 mg/dl by day 10 PP in PTX rats compared with 10.2 +/- 0.2 mg/dl in sham rats. PTX rats fed the diet containing 1.2% Ca and 0.6% P maintained a normal serum Ca level until at least day 18 PP, but their serum P levels fell gradually from approximately 5 mg/dl at 10 days to 3 mg/dl at 18 days PP. In spite of this hypophosphatemia, the litters of PTX and sham rats had gained the same amount of weight by age 16 days, indicating equal milk production in the two groups. Milk Ca, P, and total solids were not significantly different between PTX and sham rats on day 11 PP.(ABSTRACT TRUNCATED AT 250 WORDS)     

The Community Assessment of Psychic Experiences: Optimal cut‐off scores for detecting individuals with a psychotic disorder

ObjectivesThe need for a brief screening tool for psychosis is widely recognized. The Community Assessment of Psychic Experiences (CAPE) is a popular self‐report measure of psychosis, but a cut‐off score that can detect those most likely to fulfill diagnostic criteria for psychotic disorder is not established.MethodsA case–control sample from the Genetic Risk and Outcome of Psychosis Project study (N = 1375, healthy individuals, n = 507, and individuals with a psychotic disorder, n = 868), was used to examine cut‐off scores of the CAPE with receiver operating curve analyses. We examined 27 possible cut‐off scores computed from a combination of scores from the frequency and distress scales of the various factors of the CAPE.ResultsThe weighted severity positive symptom dimension was most optimal in detecting individuals with a psychotic disorder (>1.75 cut‐off; area under the curve = 0.88; sensitivity, 75%; specificity, 88%), which correctly identified 80% of the sample as cases or controls with a diagnostic odds ratio of 22.69.ConclusionsThe CAPE can be used as a first screening tool to detect individuals who are likely to fulfill criteria for a psychotic disorder. The >1.75 cut‐off of the weighted severity positive symptom dimension provides a better prediction than all alternatives tested so far.     

Do aspirin and acetaminophen affect total menstrual loss?

Two commonly taken over-the-counter analgesics, aspirin and acetaminophen, were compared for: effect on total menstrual loss, effect on total days of menstruation, and effect in reduction of pain due to headaches and/or menstrual cramps. Drugs were administered during a 4-month study according to a double-blind format. During the first 2 months, subjects ingested no drugs whatsoever during their menstrual periods. During the second 2 months, subjects ingested aspirin, acetaminophen, or placebo at the rate of two 325-mg tablets every 4 h to total 8 tablets per day during the first 3 days of their menstrual periods. Statistical analysis of the first 2 periods compared to the last 2 showed no differences in total menstrual weights. The number of days of menstruation in the placebo group was significantly lower (p = 0.0137) than in its own control or in the other groups. Neither analgesic showed a significant reduction in pain due to headache or cramps, although acetaminophen appeared to be slightly more effective than aspirin in reducing menstrual cramps.     

Soy Isoflavones: No Effects on Bone Mineral Content and Bone Mineral Density in Healthy,Menstruating Young Adult Women after One Year

Background: The effects of isoflavone-enriched soy protein on human bone mineral content (mass) and density in healthy, menstruating young adult females have not been examined in a comparative prospective investigation. Peri- and post-menopausal women have been reported to show beneficial effects of isoflavones on bone measurements. Therefore, young women may also be able to improve their accrual of peak bone mineral content (BMC) and bone mineral density (BMD) during the early adult years of bone consolidation with an isoflavone-enriched diet.

Objectives: In this controlled, double-blind intervention, we tested the hypothesis that an isoflavone-rich soy protein diet increases BMC and BMD in young adult females over a period of one year in comparison to a control group receiving soy protein that has isoflavones removed.

Design: Young healthy women of any ethnic background, 21 to 25 years of age, were divided into two groups, placebo (n = 13) and supplement (n = 15). The soy protein supplement was enriched with isoflavones (～90 mg of total isoflavones/day), whereas the control protein diet was isoflavone-deficient, even though it contained the same amount of soy protein and other ingredients as the isoflavone-rich diet. Dual-energy x-ray absorptiometric (DXA) measurements of BMC and BMD were made at baseline and at 6 and 12 months. DXA estimates of body composition, including fat mass and lean body mass, were generated from whole-body BMC measurements. BMI was calculated as weight (kg) over height (m) squared. Physical activity was assessed, and three-day dietary records were taken at entry (baseline) and at 6 and 12 months.

Results: No changes in BMD after 12 months were found in either the isoflavone-treated (treatment) group or the isoflavone-deficient (control) group. Other variables also remained essentially constant over the 12-month period, including normal menstrual patterns in both the treatment and control groups.

Conclusions: The isoflavone-rich soy preparation had no effects on BMC and BMD over a 12-month period in young healthy adult females with normal menses. An isoflavone-rich supplement appears to have little or no effect on bone in young adult women with normal ovarian function, at least over this 12-month study period.     

The development,validity, and reliability of the auditory vocal hallucination rating scale questionnaire (AVHRS-Q)

Purpose

The Auditory Vocal Hallucination Rating Scale Questionnaire (AVHRS-Q) is a short self-report measure assessing several characteristics of auditory vocal hallucinations (AVH) that was derived from a validated clinical interview (the auditory vocal hallucination rating scale; AVHRS). This study investigated the internal reliability, convergent validity, and divergent validity of the AVHRS-Q using two clinical samples.

Methods

In sample I, 32 psychiatric patients with AVH were recruited from an academic hospital service and assessed with the AVHRS and the AVHRS-Q. Data for sample II were retrospectively retrieved from a pseudonymised Routine Outcome Monitoring (ROM) database collected in the context of mental healthcare at the same academic hospital service. Data from 82 psychiatric patients with AVH were retrieved, who completed the AVHRS-Q, and measures of psychological distress (the Outcome Questionnaire; OQ-45, and the Symptom Checklist; SCL-90) and quality of life (the Manchester Short Assessment of Quality of Life; MANSA).

Results

The AVHRS-Q showed good internal consistency in both samples. Severity scores of the AVHRS-Q were strongly correlated to the severity scores of the AVHRS (r = 0.90, p < 0.01). The AVHRS-Q and AVHRS did not differ in the identification of mild and severe voice-hearers [X² (1, N = 32) = 15.71]. AVHRS-Q severity scores had moderate correlations with measures of psychological distress (OQ-45, r = 0.43, p < 0.01; SCL-90, r = 0.50, p < 0.05) and quality of life (MANSA, r = − 0.22, p < 0.01).

Conclusions

The AVHRS-Q demonstrated good reliability, convergent validity, and divergent validity, suggesting it can be applied in both clinical and research settings for a quick and reliable assessment of AVH.
