Effectiveness of a hysteroscopic tissue removal system device for hysteroscopic myomectomy on patients' quality of life: a randomized clinical trial.

PURPOSE: To evaluate the quality of life in patients treated for submucosal leiomyomas after hysteroscopic myomectomy compared to medical therapy. This is the first prospective randomized analysis comparing outcomes of medical therapy versus hysteroscopic myomectomy using the TruClear™ hysteroscopic tissue removal system to treat heavy menstrual bleeding from submucosal leiomyoma(s). METHODS: Setting: private practice and community-based hospital; subjects: female patients with symptomatic submucosal leiomyomas from 2014 to 2017. A total of 69 patients enrolled, with 47 completed. STATISTICAL ANALYSIS USED: randomization, linear mixed-effects modeling, hypothesis testing, and intent-to-treat analysis. Each patient was randomized to oral contraceptive pills/progesterone releasing intrauterine device or hysteroscopic myomectomy. Each patient was to complete the Uterine Fibroid Symptom and Health-related Quality of Life (UFS-QOL) questionnaire at baseline, one month, three months, and greater than or equal to six months after treatment. MAIN OUTCOME MEASURED: Primary outcome was the health-related quality of life (HR-QOL), as reflected from UFS-QOL scores. Contrasts were constructed from a linear mixed-effects model to compare the two treatment groups for changes from baseline in UFS-QOL scores. RESULTS: UFS-QOL scores were similar at baseline between the two treatment groups. There was an overall improvement in all UFS-QOL scores within each group. Higher improvement scores were noted in the surgical group compared to the medical group for almost all UFS-QOL scores. At ≥ 6 months, in comparison to the medically managed patients, the most considerable score improvements for the surgical group were reported in HR-QOL concern, activities, self-consciousness and symptom severity scores having mean change scores (95% CIs) of 35.3, 28.9, 28.6, and 32.2, respectively. CONCLUSION: Although there was no statistical difference in the change degree of improvement of overall quality of life among patients with symptomatic submucosal leiomyomas who received medical or surgical treatments in the study, there were greater differences in improvements in health-related quality of life scores over time after surgical treatment.

Food Insecurity Influences Weight Trajectory in Children with Obesity.

Background: Social disadvantage is associated with children's risk of being overweight or obese, but little is known about how it impacts weight trajectory. This longitudinal analysis examines food insecurity and weight change over time among low-income children in a multidisciplinary weight management clinic. Methods: Food insecurity was assessed between 2008 and 2016 among 794 low-income patients (household income <$60k/year) who attended 3234 visits. Mixed-effects growth curve modeling was used to examine the association between baseline food security status and weight trajectory, using percentage of the 95th percentile for BMI (%BMIp95). Random effects (each child's growth curve) and fixed effects (food insecurity, starting age and %BMIp95, demographics, and months since the initial visit) were modeled, and interactions between food insecurity and elapsed time estimated the influence of food insecurity on weight trajectory. Results: Mean %BMIp95 was 129% (SD 24%), corresponding to severe obesity. Thirty percent of patients were food-insecure at baseline. After adjusting for other factors, monthly change in %BMIp95 was significantly smaller for food-insecure children compared to food-secure peers (difference in the coefficients for slope: 0.13, SE 0.05, p = 0.009). The modeled 12-month change in %BMIp95 was significant for food-secure children (-2.28, SE 0.76, p = 0.0026), but not for food-insecure children (-1.54, SE 1.22, p = 0.21). Conclusion: Household food insecurity was associated with a less optimal weight trajectory among children with obesity.

Management of Breast Cancer during Pregnancy: Are We Compliant with Current Guidelines?

Introduction The purpose of this study was to evaluate the management of patients with breast cancer in pregnancy treated at the Advocate Health Care, to determine whether these patients were treated according to guidelines for pregnant patients, which aim to maximize both fetal and maternal outcomes. Methods A retrospective chart review was performed at the Advocate Lutheran General Hospital, Christ Medical Center, and Illinois Masonic Medical Center from 2002 to 2012 on patients diagnosed with breast cancer during pregnancy using ICD-9 (International Classification of Diseases - 9th version) codes. Results Eleven patients between 12 and 37 weeks' gestation matched the search criteria. One patient terminated the pregnancy. Patients in our study were treated appropriately according to guidelines with the following exceptions. Trastuzumab was used in one patient during pregnancy which likely caused the oligohydramnios resulting in an induction of labor at 33 weeks. Three patients were delivered preterm between 34 and 36 weeks without an obstetric indication. Two patients underwent sentinel node biopsy. Conclusion The diagnosis of breast cancer in pregnancy is an infrequent but devastating diagnosis that is likely to increase. Although sentinel lymph node biopsy is not generally recommended in pregnancy, this may be an outdated guideline as using a low-dose lymphoscintigraphic technique appears to be safe in pregnancy.

Qualitative and/or quantitative drinking water recommendations for pediatric obesity treatment.

OBJECTIVE: The qualitative recommendation to 'drink water instead of caloric beverages' may facilitate pediatric obesity treatment by lowering total energy intake. The quantitative recommendation to 'drink enough water to dilute urine' might further facilitate weight loss by increasing fat oxidation via cell hydration-mediated changes in insulin. METHODS: This 8 week randomized intervention tested whether both qualitative-plus-quantitative (QQ) drinking water recommendations result in more weight loss than the qualitative recommendation alone (Q) in 25 children (9-12y) with body mass index at or above the 85th Percentile, given a reduced glycemic diet and usual physical activity. Random urine osmolality, saliva insulin, and body weight were assessed weekly. Mixed models explored if insulin mediated an effect of urine osmolality on weight loss. RESULTS: In intention-to-treat analyses, QQ and Q participants did not differ significantly with respect to level of urine osmolality, saliva insulin, or weight loss. Only 4 out of 16 QQ participants complied with instruction to drink enough water to dilute urine, however. In completers analyses, the compliant QQ participants, who diluted urine osmolality from 910 ± 161 mmol/kg at baseline to below 500 mmol/kg over time (8 week mean±SE: 450 ± 67 mmol/kg), had significantly lower saliva insulin over time (8 week mean±SE: 13 ± 8 pmol/l vs. 22 ± 4 pmol/l) and greater weight loss (mean ± SE: -3.3 ± 0.7kg vs. -2.0 ± 0.5 kg) than compliant Q participants (7 out of 9 participants) who maintained elevated urine osmolality over time (8- week mean±SE: 888 ± 41 mmol/kg). Urine osmolality below 500 mmol/kg was significantly associated with weight loss. Change in saliva insulin partially explained the association. CONCLUSIONS: QQ recommendations may increase weight loss for those able to dilute urine. Work is warranted to pursue cell hydration effects of drinking water for pediatric obesity treatment.

Human T-cell leukemia virus type I infection in various recipients of transplants from the same donor.

BACKGROUND: The human T-cell lymphotrophic virus (HTLV) causes adult T-cell leukemia-lymphoma, tropical spastic paraparesis-HTLV type I, and associated myelopathy. METHODS: An analysis was performed of serum samples from a multiorgan donor and the five recipients. Also studied was the donor's family and the partner of one of the renal recipients. Serologic detection of anti-HTLV antibodies was carried out by enzyme immunoassay and Western blot to confirm and discriminate between HTLV types. Analysis of proviral DNA was performed by polymerase chain reaction and sequenced in the long terminal repeat region and the env gene. Peripheral blood mononuclear cell samples from all the recipients of the HTLV-I-positive organs and the donor's mother were studied. RESULTS: Two years after transplantation, three organ recipients positive for antibodies to HTLV-I were detected (two kidney transplants and one liver). All the recipients' serum samples were negative at the time of transplantation except those from the multiorgan donor. The donor's mother was born in Venezuela and was confirmed positive for antibodies to HTLV-I. The remaining family members were negative. HTLV-I DNA sequences were recovered, amplified, and sequenced from all the samples from the HTLV-I-positive recipients and the donor's mother. The homology of HTLV-I sequences was 100% in all cases. CONCLUSIONS: The authors are reporting the first documented case of HTLV-I infection in several transplant recipients sharing the same donor. The donor was infected by vertical transmission. HTLV-I infection has devastating consequences for some immunocompromised organ recipients. This emphasizes the need for a systematic survey of HTLV antibodies in all potential donors.

Integrating fuzzy logic, optimization, and GIS for ecological impact assessments.

Appraisal of ecological impacts has been problematic because of the behavior of ecological system and the responses of these systems to human intervention are far from fully understood. While it has been relatively easy to itemize the potential ecological impacts, it has been difficult to arrive at accurate predictions of how these impacts affect populations, communities, or ecosystems. Furthermore, the spatial heterogeneity of ecological systems has been overlooked because its examination is practically impossible through matrix techniques, the most commonly used impact assessment approach. Besides, the public has become increasingly aware of the importance of the EIA in decision-making and thus the interpretation of impact significance is complicated further by the different value judgments of stakeholders. Moreover, impact assessments are carried out with a minimum of data, high uncertainty, and poor conceptual understanding. Hence, the evaluation of ecological impacts entails the integration of subjective and often conflicting judgments from a variety of experts and stakeholders. The purpose of this paper is to present an environmental impact assessment approach based on the integration fuzzy logic, geographical information systems and optimization techniques. This approach enables environmental analysts to deal with the intrinsic imprecision and ambiguity associated with the judgments of experts and stakeholders, the description of ecological systems, and the prediction of ecological impacts. The application of this approach is illustrated through an example, which shows how consensus about impact mitigation can be attained within a conflict resolution framework.

Rotavirus / Rotavirus

Los rotavirus son los agentes etiológicos de las enfermedades diarreicas severas de infantes y niños en todo el mundo. Aunque son las enfermedades infantiles más comunes a nivel mundial, adquieren un significado especial en los países en desarrollo, donde constituyen la mayor causa de mortalidad en la niñez.
