Does preoperative locally applied estrogen treatment facilitate prolapse-associated symptoms in postmenopausal women with symptomatic pelvic organ prolapse? A randomised controlled double-masked, placebo-controlled, multicenter study

BJOG. 2021 Aug 31. doi: 10.1111/1471-0528.16894. Online ahead of print.

ABSTRACT

OBJECTIVE: To evaluate if locally applied vaginal estrogen affects prolapse-associated complaints compared to placebo treatment in postmenopausal women prior to surgical prolapse repair.

DESIGN: Randomised, double-masked, placebo-controlled, multicenter study.

SETTING: Urogynaecology unit at the Medical University of Vienna and University Hospital of Tulln.

POPULATION: Postmenopausal women with symptomatic pelvic organ prolapse and planned surgical prolapse repair.

METHODS: Women were randomly assigned local estrogen cream or placebo cream 6 weeks preoperatively.

MAIN OUTCOME MEASURES: Primary outcome was differences in subjective prolapse-associated complaints after 6 weeks of treatment prior to surgery assessed with the comprehensive German pelvic floor questionnaire. Secondary outcomes included differences in other pelvic floor associated complaints (bladder, bowel, sexual function).

RESULTS: Out of 120 randomised women 103 (86%) remained for final analysis. After 6 weeks of treatment prolapse domain score did not differ between the estrogen and the placebo group (4.4 ± 0.19 vs. 4.6 ± 0.19; mean difference: – 0.21; 95%CI: -0.74 to 0.33; P=.445). Multivariate analysis, including only women with intervention, showed that none of the confounding factors modified response to estradiol.

CONCLUSIONS: These results demonstrate that preoperative locally applied estrogen does not ameliorate prolapse-associated symptoms in postmenopausal women with symptomatic pelvic organ prolapse.

Educational actions on first aid for early childhood education teachers: a quasi-experimental study

Rev Esc Enferm USP. 2021 Aug 30;55:e20210025. doi: 10.1590/1980-220X-REEUSP-2021-0025. eCollection 2021.

ABSTRACT

OBJECTIVE: To assess the early childhood education teachers’ knowledge about first aid before and after the participation in an educational action.

METHOD: Quantitative research with a quasi-experimental pre- and post-test design, carried out with 45 teachers from four early childhood education schools. For data collection, an instrument with questions regarding the characterization of the participants and knowledge about first aid was used. Data were analyzed through statistical techniques, using the Shapiro Wilk and Wilcoxon tests.

RESULTS: There was an increase in the number of correct answers to the questions and improvement regarding grades, with an increase in the score from pre- to post-test by 5.17 points and with a significant comparison of sums.

CONCLUSION: Carrying out educational actions on first aid increases the knowledge of early childhood education teachers on the subject and the nurses’ role as health educators is highlighted.

Treatment of depression: Are psychotropic drugs appropriately dosed in women and in the elderly? Dosages of psychotropic drugs by sex and age in routine clinical practice

Hum Psychopharmacol. 2021 Aug 31:e2809. doi: 10.1002/hup.2809. Online ahead of print.

ABSTRACT

BACKGROUND: Several researchers have shown higher concentration-dose ratios of psychotropic drugs in women and the elderly. Therefore, lower dosages of psychotropic drugs may be recommended in women and the elderly. This study describes sex- and age-related dosage of psychotropic drugs prescribed to patients with major depressive disorder (MDD) in routine clinical practice.

METHOD: Influence of sex and age on dosages are analysed for the 10 most commonly prescribed drugs in our dataset consisting of 32,082 inpatients with MDD. Data stems from the European drug safety program “Arzneimittelsicherheit in der Psychiatrie”. The observed sex and age differences in prescriptions are compared to differences described in literature on age- and gender-related pharmacokinetics.

RESULTS: Among patients over 65 years, a statistically significant decrease in dosages with increasing age (between 0.65% and 2.83% for each increasing year of age) was observed, except for zopiclone. However, only slight or no influence of sex-related adjustment of dosage in prescriptions was found.

CONCLUSION: Age appears to influence adjustment of dosage in most psychotropic drugs, but to a lower extent than data on age-related pharmacokinetics suggests. Although literature also suggests that lower dosages of psychotropic drugs may be appropriate for females, this study found women are usually prescribed the same dosage as men.

Analysis and optimization of 15-minute community life circle based on supply and demand matching: A case study of Shanghai

PLoS One. 2021 Aug 31;16(8):e0256904. doi: 10.1371/journal.pone.0256904. eCollection 2021.

ABSTRACT

The 15-minute community life circle (15min-CLC) strategy is one of Shanghai’s important methods for building a global city and facing a society with a more diverse population structure in the future. In the existing research, the balance between the construction of the life circle and the needs of the people in the life circle still needs to be further fulfilled. This paper is based on the city’s multi-source large data set including 2018 AutoNavi POI (Point of Interests), OSM (OpenStreetMap) road network data and LandScan population data set, and evaluates the current status of Shanghai’s 15min-CLC through the fusion of kernel density estimation, service area analysis and other statistical models and proposes relevant optimization suggestions. The results show that there are the following shortcomings: (1) From the perspective of different types of infrastructure service facilities, the spatial construction of Shanghai’s overall life service facilities and shopping service facilities needs to be optimized. (2) From the perspective of comprehensive evaluation, the comprehensive service convenience of infrastructure service facilities in the downtown area is relatively high, while the comprehensive service convenience of urban infrastructure service facilities in the suburbs and outer suburbs is relatively low; The diversity of basic service facilities in the 15min-CLC in the downtown area is more consistent with the population distribution; However, in the peripheral areas of the urban area, too many infrastructure service facilities have been constructed. Based on the above shortcomings and the perspective of supply and demand matching, relevant optimization strategies are proposed in different regions and different types of infrastructure service facilities: (1) focus on the construction of basic service facilities in the urban fringe and urban-rural areas, improve the full coverage of the basic service facilities, and appropriately reduce the number of basic service facilities in the downtown area. (2) The development of community business models can be used to promote the development of new life service facilities and shopping service facilities. (3) Improve community medical institutions through facility function conversion, merger and reconstruction, etc. (4) Optimize the hierarchical basic service facility system and improve the population supporting facilities of basic service facilities in the 15min-CLC. This paper incorporates people’s needs and concerns on the living environment into the 15min-CLC evaluation model, and uses Shanghai as an example to conduct research, summarizes the existing shortcomings, and proposes corresponding optimization strategies based on the matching of supply and demand. This article attempts to explore a replicable 15min-CLC planning model, so that it can be extended to the Yangtze River Delta urban agglomeration, to provide reference for further research on the 15min-CLC, and to promote urban construction under the concept of sustainable development.

Association between spirituality and quality of life of women with breast cancer undergoing radiotherapy

Rev Esc Enferm USP. 2021 Aug 30;55:e20200476. doi: 10.1590/1980-220X-REEUSP-2020-0476. eCollection 2021.

ABSTRACT

OBJECTIVE: To verify whether there is an association between spirituality/religiosity and quality of life of women with breast cancer undergoing radiotherapy.

METHOD: Cross-sectional, quantitative study performed between May and July 2019 in an Oncology Hospital of Porto Alegre state, Brazil. A sociodemographic questionnaire and the instruments EORTC-QLQ-C30 and WHOQOL-SRPB were applied. The data were verified through Shapiro-Wilk test, Pearson correlation coefficient, and Spearman.

RESULTS: The sample comprised 108 women with a mean age of 56, predominantly white, married, and with incomplete primary education. A positive correlation between “Overall quality of life score” with all facets of spirituality, as well as a negative correlation for the symptoms “Fatigue”, “Insomnia”, and “Diarrhea” with some aspects of spirituality, such as “Faith”, were observed.

CONCLUSION: The statistical significance of the correlation has positively associated spirituality/religiosity and quality of life in women with breast cancer undergoing radiotherapy. Understanding spirituality as a preponderant factor in quality of life contributes to positive nursing care interference, with individualized orientation and care to each woman.

Impact of the dog population and household environment for the maintenance of natural foci of Leishmania infantum transmission to human and animal hosts in endemic areas for visceral leishmaniasis in Sao Paulo state, Brazil

PLoS One. 2021 Aug 31;16(8):e0256534. doi: 10.1371/journal.pone.0256534. eCollection 2021.

ABSTRACT

When it comes to visceral leishmaniasis (VL) in Brazil, one of the main targets of public health policies of surveillance is the control of domestic canine reservoirs of Leishmania infantum. This paper aims to evaluate the effect of the dog population and household environment for the maintenance of natural foci in the transmission to human and animal hosts in an endemic city for VL, Bauru, in Brazil. We collected 6,578 blood samples of dogs living in 3,916 households from Nov.2019 to Mar.2020 and applied geospatial models to predict the disease risk based on the canine population. We used Kernel density estimation, cluster analysis, geostatistics, and Generalized Additive Models (GAM). To validate our models, we used cross-validation and created a receiver operating characteristic (ROC) curve. We found an overall canine VL (CVL) seroprevalence of 5.6% for the sampled dogs, while for the households, the positivity rate was 8.7%. Odds ratios (OR) for CVL increased progressively according to the number of canines for >2 dogs (OR 2.70); households that already had CVL in the past increased the chances for CVL currently (OR 2.73); and the cases of CVL increase the chances for human VL cases (OR 1.16). Our models were statistically significant and demonstrated a spatial association between canine and human disease cases, mainly in VL foci that remain endemic. Although the Kernel density ratio map had the best performance (AUC = 82), all the models showed high risk in the city’s northwest area. Canine population dynamics must be considered in public policies, and geospatial methods may help target priority areas and planning VL surveillance in low and middle-income countries.

Sensitive proportion in ranked set sampling

PLoS One. 2021 Aug 31;16(8):e0256699. doi: 10.1371/journal.pone.0256699. eCollection 2021.

ABSTRACT

This paper considers the concomitant-based rank set sampling (CRSS) for estimation of the sensitive proportion. It is shown that CRSS procedure provides an unbiased estimator of the population sensitive proportion, and it is always more precise than corresponding sample sensitive proportion (Warner SL (1965)) that based on simple random sampling (SRS) without increasing sampling cost. Additionally, a new estimator based on ratio method is introduced using CRSS protocol, preserving the respondent’s confidentiality through a randomizing device. The numerical results of these estimators are obtained by using numerical integration technique. An application to real data is also given to support the methods.

Budbreak patterns and phytohormone dynamics reveal different modes of action between hydrogen cyanamide- and defoliant-induced flower budbreak in blueberry under inadequate chilling conditions

PLoS One. 2021 Aug 31;16(8):e0256942. doi: 10.1371/journal.pone.0256942. eCollection 2021.

ABSTRACT

Under inadequate chilling conditions, hydrogen cyanamide (HC) is often used to promote budbreak and improve earliness of Southern highbush blueberry (Vaccinium corymbosum L. interspecific hybrids). However, HC is strictly regulated or even banned in some countries because of its high hazardous properties. Development of safer and effective alternatives to HC is critical to sustainable subtropical blueberry production. In this study, we examined the efficacy of HC and defoliants as bud dormancy-breaking agents for ‘Emerald’ blueberry. First, we compared water control, 1.0% HC (9.35 L ha-1), and three defoliants [potassium thiosulfate (KTS), urea, and zinc sulfate (ZS)] applied at 6.0% (28 kg ha-1). Model fitting analysis revealed that only HC and ZS advanced both defoliation and budbreak compared with the water control. HC-induced budbreak showed an exponential plateau function with a rapid phase occurring from 0 to 22 days after treatment (DAT), whereas ZS-induced budbreak showed a sigmoidal function with a rapid phase occurring from 15 to 44 DAT. The final budbreak percentage was similar in all treatments (71.7%-83.7%). Compared with the water control, HC and ZS increased yield by up to 171% and 41%, respectively, but the yield increase was statistically significant only for HC. Phytohormone profiling was performed for water-, HC- and ZS-treated flower buds. Both chemicals did not increase gibberellin 4 and indole-3-acetic acid production, but they caused a steady increase in jasmonic acid (JA) during budbreak. Compared with ZS, HC increased JA production to a greater extent and was the only chemical that reduced abscisic acid (ABA) concentrations during budbreak. A follow-up experiment tested ZS at six different rates (0-187 kg ha-1) but detected no significant dose-response on budbreak. These results collectively suggest that defoliants are not effective alternatives to HC, and that HC and ZS have different modes of action in budbreak induction. The high efficacy of HC as a dormancy-breaking agent could be due to its ability to reduce ABA concentrations in buds. Our results also suggest that JA accumulation is involved in budbreak induction in blueberry.

The hidden side of animal cognition research: Scientists’ attitudes toward bias, replicability and scientific practice

PLoS One. 2021 Aug 31;16(8):e0256607. doi: 10.1371/journal.pone.0256607. eCollection 2021.

ABSTRACT

Animal cognition research aims to understand animal minds by using a diverse range of methods across an equally diverse range of species. Throughout its history, the field has sought to mitigate various biases that occur when studying animal minds, from experimenter effects to anthropomorphism. Recently, there has also been a focus on how common scientific practices might affect the reliability and validity of published research. Usually, these issues are discussed in the literature by a small group of scholars with a specific interest in the topics. This study aimed to survey a wider range of animal cognition researchers to ask about their attitudes towards classic and contemporary issues facing the field. Two-hundred and ten active animal cognition researchers completed our survey, and provided answers on questions relating to bias, replicability, statistics, publication, and belief in animal cognition. Collectively, researchers were wary of bias in the research field, but less so in their own work. Over 70% of researchers endorsed Morgan’s canon as a useful principle but many caveated this in their free-text responses. Researchers self-reported that most of their studies had been published, however they often reported that studies went unpublished because they had negative or inconclusive results, or results that questioned “preferred” theories. Researchers rarely reported having performed questionable research practices themselves-however they thought that other researchers sometimes (52.7% of responses) or often (27.9% of responses) perform them. Researchers near unanimously agreed that replication studies are important but too infrequently performed in animal cognition research, 73.0% of respondents suggested areas of animal cognition research could experience a ‘replication crisis’ if replication studies were performed. Consistently, participants’ free-text responses provided a nuanced picture of the challenges animal cognition research faces, which are available as part of an open dataset. However, many researchers appeared concerned with how to interpret negative results, publication bias, theoretical bias and reliability in areas of animal cognition research. Collectively, these data provide a candid overview of barriers to progress in animal cognition and can inform debates on how individual researchers, as well as organizations and journals, can facilitate robust scientific research in animal cognition.

Is there an inflammatory stimulus to human term labour?

PLoS One. 2021 Aug 31;16(8):e0256545. doi: 10.1371/journal.pone.0256545. eCollection 2021.

ABSTRACT

Inflammation is thought to play a pivotal role in the onset of term and some forms of preterm labour. Although, we recently found that myometrial inflammation is a consequence rather than a cause of term labour, there are several other reproductive tissues, including amnion, choriodecidua parietalis and decidua basalis, where the inflammatory stimulus to labour may occur. To investigate this, we have obtained amnion, choriodecidual parietalis and decidua basalis samples from women at various stages of pregnancy and spontaneous labour. The inflammatory cytokine profile in each tissue was determine by Bio-Plex Pro® cytokine multiplex assays and quantitative RT-PCR. Active motif assay was used to study transcription activation in the choriodecidua parietalis. Quantitative RT-PCR was use to study the pro-labour genes (PGHS-2, PGDH, OTR and CX43) in all of the tissues at the onset of labour and oxytocin (OT) mRNA expression in the choriodecidual parietalis and decidua basalis. Statistical significance was ascribed to a P value <0.05. In the amnion and choriodecidua parietalis, the mRNA levels of various cytokines decreased from preterm no labour to term no labour samples, but the protein levels were unchanged. The choriodecidua parietalis showed increase in the protein levels of IL-1β and IL-6 in the term early labour samples. In the amnion and decidua basalis, the protein levels of several cytokines rose in term established labour. The multiples of the median derived from the 19-plex cytokine assay were greater in term early labour and term established labour samples from the choriodecidua parietalis, but only in term established labour for myometrium. These data suggest that the inflammatory stimulus to labour may begin in the choriodecidua parietalis, but the absence of any change in prolabour factor mRNA levels suggests that the cytokines may act on the myometrium where we observed changes in transcription factor activation and increases in prolabour gene expression in earlier studies.
