Characteristics of the Menstrual Cycle After Discontinuation of Oral Contraceptives

Background: Menstrual cycle function may continue to be altered after discontinuation of oral contraceptives (OC). Few studies have been published on the effects of recent OC use on menstrual cycle parameters; none have examined characteristics of the menstrual flow or the quality of cervical mucus. The purpose of this retrospective matched cohort study is to assess biomarkers of the menstrual cycle after discontinuation of OCs. Methods: Among a sample of women who daily recorded observations of menstrual cycle biomarkers, 70 women who had recently discontinued OCs were randomly matched by age and parity with 70 women who had not used OCs for at least 1 year. Outcomes investigated included overall cycle length, length of the luteal phase, estimated day of ovulation, duration of menstrual flow, menstrual intensity, and mucus score. Differences between recent OC users and controls were assessed using random effects modeling. Results: Recent OC users had statistically significantly lower scores for mucus quality for cycles 1 and 2. Additionally, OC users had a later estimated day of ovulation that was statistically significant in cycle 2 and a decreased intensity of menstrual flow that was significant in the first four cycles (difference = −0.48 days). In random effects modeling, all these parameters were significantly different for the first six cycles combined. Conclusions: Menstrual cycle biomarkers are altered for at least two cycles after discontinuation of OCs, and this may help explain the temporary decrease in fecundity associated with recent OC use

Creativity and Thinking Skills Integrated into a Science Enrichment Unit on Flooding

Floods that used to happen every hundred years are now occurring more frequently. Human influences on the damage inflicted by flooding need to be well-understood by future voters and property-owners. Therefore, the timely topic of flooding was used as the focus of a special multi-grade enrichment short course taught by two university education professors for 26 preK-8th grade high-achieving and creative students. During the course, students listened to guest speakers (city council member, meteorologist, and environmentalist), watched two flood-related videos, read books on floods, viewed electronic presentations related to dams and recent floods, discussed causes, effects, and mitigations of flooding, and devised creative games from recycled materials to teach peers about flood concepts. The de Bono CoRT Breadth thinking skill system was used to organize many of the course activities. The flood lesson activities were relevant to these students who had experienced a flood of the city’s river the previous year and challenged students more than their typical classroom activities, an important finding considering that many gifted students drop out of school because of irrelevant and non-demanding class work. The course broadened students’ knowledge of floods and assisted them in thinking beyond the immediate situation

Short-line railroad managers discuss class I railroads

Managers/owners of short-line railroads were queried about three issues: (1) How would you describe your company’s business relationship with the Class I railroad(s) with which you interchange traffic; (2) Do you believe that mergers between Class I railroads have been good or bad for short-line railroads; and (3) Besides merger activity, what do you believe will be the most important trend for Class I railroads in the next 10 years

A Similar but Distinctive Pattern of Impaired Cortical Excitability in First-Episode Schizophrenia and ADHD

Background: First-episode schizophrenia (FE-SZ) and attention deficithyperactivity disorder (ADHD) are both neuropsychiatric disordersassociated with an impaired dopaminergic transmission. Though displayingdifferent clinical phenotypes, a common pathophysiological pathway isdiscussed controversially. Several studies using transcranial magneticstimulation (TMS) revealed abnormalities in human motor cortexexcitability in both schizophrenia and ADHD patients. Studies oncortical excitability comparing these two diseases directly are lacking.Method: In this study, a total of 94 subjects were analyzed.Twenty-fiveFE-SZ patients were directly compared with 28 ADHD patients and 41healthy controls (HC). We investigated cortical excitability (inhibitoryand facilitatory networks) with single- and paired-pulse TMS to the leftand right motor cortex. Results: Compared to HC, FE-SZ/ADHD patientsdisplayed an impaired cortical inhibition over the left hemisphere.Apart from an enhanced intracortical facilitation, FE-SZ patients didnot differ compared to ADHD patients in the main outcome measures. Bothpatient groups presented a dysfunctional hemispheric pattern of corticalinhibition and facilitation in comparison with HC. Conclusion: Theresults of this study indicate a pattern of cortical disinhibition andabnormal hemispheric balance of intracortical excitability networks intwo different psychiatric diseases. These effects might be associatedwith an imbalance in GABAergic and dopaminergic transmission and mightprovide evidence for a common pathophysiological pathway of bothdiseases

Virulent T4 Acanthamoeba causing keratitis in a patient after swimming while wearing contact lenses in Southern Brazil

Several strains of free-living amoebae belonging to the genus Acanthamoeba can cause a painful sight-threatening disease of the cornea known as Acanthamoeba keratitis (AK). The numbers of AK cases keep rising worldwide mainly due to an increase in contact lens wearers and lack of hygiene in the maintenance of contact lenses and their cases. We report a case of AK in a healthy young woman admitted to the Hospital de Clinicas in Porto Alegre, southern Brazil. Corneal scrapings were examined for the presence of Acanthamoeba strains. The initial isolate was characterized by morphological and genotypic properties. The isolate belonged to group III according to Pussard and Pons’ cyst morphology. Analysis of its 18S rDNA sequence identified the isolate as genotype T4. The T4 genotype is the most commonly reported among keratitis isolates and the most common in environmental samples
