Authors: Anukriti Kumari , Guleria Kiran , Tyagi Vipin , Suneja Amita , Banerjee B D
Published: April 2021

Purpose of investigation: The oxytocin (OXT)-oxytocin receptor (OXTR) system provides a promising candidate gene for studies of genetic contributions to prematurity. The author studies the quantification and comparison of oxytocin receptor (OXTR) gene expression and serum OXT levels in the blood and amnion of women delivering preterm and evaluation of the correlation between OXTR gene expression in blood and amnion with serum OXT levels in them. Material and methods: Seventy pregnant women in spontaneous labor delivering vaginally preterm i.e., < 37 weeks and an equal number of matched controls delivering spontaneously at term (37–42 weeks) were recruited. Maternal serum OXT levels were quantified by ELISA collected in the active stage of labor i.e., 4 cm cervical dilatation. Gene expression studies in the maternal blood and amnion were done by using real-time quantitative polymerase chain reaction (RT-qPCR). Results: The mean serum OXT level in preterm labor (PTL) was 48.56 ± 6.97 pg/mL; significantly higher than in controls (43.00 ± 3.96 pg/mL), P < 0.001. OXTR gene expression in maternal blood (2.5 times) as well as in amnion (3.5 times) was significantly higher in PTL. A significant positive correlation was observed between serum OXT levels and OXTR gene expression in amnion (r = -0.190, P = 0.025). Conclusions: The serum OXT levels and OXTR gene expression in amnion surge significantly in the active phase of PTL. Thus, amnion probably links OXT-PTGs (prostaglandins) autocrine paracrine circuit to facilitate PTL. Future studies are needed to devise better OXTR receptor antagonists preferably acting on amnionic OXTRs to prevent inflammatory pathways leading to PTL.

Published: April 2021

Purpose: To determine which factors predict pregnancy outcome in women aged 40 years and above who underwent in-vitro fertilization. Method: We conducted a retrospective case-control study of 631 women aged 40–46 years, who underwent a total of 904 IVF cycles with autologous gametes. We used stepwise logistic regression analysis to develop predictors of pregnancy, clinical pregnancy and live birth outcomes. Data are presented as mean ± SD, percentage and confidence intervals. Results: Predictors of live birth included maternal (95% CI: 0.36–0.78) and paternal (95% CI: 0.62–0.94) age, the number of follicels > 14 mm (95% CI: 1.2–3.2), the number of oocytes collected (95% CI: 1.3–2.9) the number of metaphase II oocytes (95% CI: 1.3–2.4) and the number of cleavage stage embryos (95% CI: 1.8–2.6). The predictors of pregnancy and clinical pregnancy were similar but did not include male age (P > 0.05). To further determine the role of male age in live birth a control group of women younger than 40 years was collected. Male age was not a significant predictor of live birth among younger women (P = 0.42). Conclusions: Female age and better ovarian stimulation were confirmed as predictors of outcomes in older women doing IVF. However, male age was also noted to be a significant individual predictor of live birth in women over 40 years of age, but not in younger women doing IVF.

Published: April 2021

Objective: This study aims to investigate the etiological and bleeding risk factors of cesarean scar pregnancy (CSP) and attempts to determine the clinical value of uterine artery embolization (UAE) combined with curettage, methotrexate (MTX) chemotherapy combined with curettage, and uterine curettage alone in terminating CSP. Materials and methods: A total of 154 patients with CSP and 155 patients with cicatricial uterus termination of pregnancy in the same period who were hospitalized in the Department of Obstetrics and Gynecology, Second Affiliated Hospital of Nanchang University from January 2013 to March 2020 were enrolled in this study. The clinical characteristics of the two groups were statistically analyzed, and CSP patients were divided into the UAE + uterine curettage group (n = 49), MTX + uterine curettage group (n = 33) and uterine curettage alone group (n = 72) according to different treatment methods. The scar thickness, intraoperative blood loss, time to resumption of menstruation and other indicators were compared and analyzed among the three groups. Results: The proportion of CSP patients with cesarean section time < 24 months and ≥ 60 months was significantly higher than that of pregnant women with scar uterus. In the MTX + curettage group, 2 cases had intraoperative blood loss of more than 200 mL where the gestational age was more than 10 weeks, in which they were given Foley’s catheter balloon compression hemostasis. In patients with simple uterine curettage, 6 cases had intraoperative blood loss of more than 200 mL with a gestational age of more than 8 weeks. Two cases were given emergency interventional treatment, while four underwent Foley catheter balloon compression hemostasis. The recovery time of β-hCG in the UAE + curettage group was shortest, which was found to be statistically significant. Furthermore, menopause time, blood β-hCG level and gestational sac diameter were found to be positively correlated with the amount of bleeding, while the thickness of the uterine scar was negatively correlated with the amount of bleeding. Conclusions: Gestational age, blood β-hCG level before treatment, gestational sac diameter and scar thickness were early warning indicators to evaluate the amount of bleeding in the treatment of CSP. UAE OR MTX pretreatment before cesarean section in CSP patients can significantly reduce intraoperative blood loss, and MTX + curettage is safe and effective for patients with abundant blood flow around the gestational sac with a gestational age of 8–10 weeks. However, in regard to CSP patients with a gestational age greater than 10 weeks and rich blood flow around the gestational sac, UAE pretreatment followed by termination of pregnancy is preferred. In case of hemorrhage during uterine curettage, the emergency intrauterine balloon compression can achieves adequate hemostasis.
Value of computed tomography-defined visceral fat area as a risk factor for endometrial cancer
Authors: Cho Jae-hyun , Kim Jeong Sig , Park Suyeon , Kim Woo Young
Published: April 2021

Objective: Obesity is a risk factor for endometrial cancer. Recently, visceral fat is strongly associated with obesity-related carcinogenesis, more than subcutaneous fat. In this study, we hypothesized that the visceral fat measured by computed tomography (CT) contributes to the occurrence of endometrial cancer. Methods: A retrospective chart review of patients undergoing primary surgery for endometrial cancer was conducted. The volume of visceral fat was measured by CT scans performed at the fourth lumbar level for all participants. Body fat distributions assessed by a direct method in 52 endometrial cancer cases were compared with those of age- and BMI-matched healthy community controls. Results: Case group showed significantly higher mean visceral fat area (VFA; 76.2 ± 25.0 vs. 62.2 ± 13.9 cm2, P = 0.007). The mean total fat area (TFA; 270.3 ± 99.9 vs. 238.9 ± 53.8 cm2, P = 0.137) and subcutaneous fat area (SFA; 194.2 ± 86.5 vs. 176.7 ± 45.8 cm2, P = 0.315), however, presents no significant differences. VFA showed lower correlation with BMI (r2 = 0.299, P < 0.001) than to SFA (r2 = 0.528, P < 0.001) or TFA (r2 = 0.584, P < 0.001). In receiver operator characteristic (ROC) curve, at a VFA value of 70.8 cm2, sensitivity and specificity of the case group was 55.8% and 75%, respectively. Conclusion: Increased abdominal visceral fat is associated with endometrial cancer risk and can be predicted by measuring CT scans. Furthermore, as the most independent factor of BMI, VFA may provide additional information for representative risks of endometrial cancer.

Published: April 2021

The aim of this study was to investigate the clinical outcomes of fresh and frozen-thawed blastocyst transfer deriven from the same ICSI cycle because of male infertility. 2372 couples undergoing a total of 5075 ICSI cycles (2372 fresh + 2703 frozen embryo transfer) were enrolled in the study. Female factor infertility cases were excluded to prevent from the contribution of maternal factors that would influence the outcomes dramatically. Only the cycles for which day 5 blastocyst transfer was performed, had at least 1 surplus blastocyst available for freezing, and had at least one frozen embryo transfer (FET) cycle were included in the study. Clinical pregnancy rates and live birth rates were compared between fresh and FET cycles. No statistically significant difference was obtained in clinical pregnancy rates and live birth rates of fresh versus FET cycles of day 5 transfers, regardless of the number of embryos transferred. According to the results of the recent study, frozen embryo cycles appear to be as effective as fresh ICSI cycles provided that the patients’ embryos can develop into blastocysts, which is proven by using the same patient as the control group regardless of the result of previous ICSI attempt but further research is required to test the efficacy in terms of cost-effectiveness and the duration for conception.

Published: April 2021

The aims of the study were to investigate the prevalence of anxiety and depression and to correlate symptoms of anxiety and depression with abnormal uterine bleeding (AUB) in Korean women. Our study included 124 Korean premenopausal women aged 15–55 without treatment of psychiatric disorders, who visited one university hospital due to AUB between September 2015 and December 2019. The Korean Beck Anxiety Inventory (K-BAI) and the Korean Beck Depression-II (K-BDI-II) were used to assess Anxiety and depression symptoms. We also analyzed obstetrical and clinical data to assess the association between anxiety and depression with AUB. The cut-off scores for possible anxiety disorder were met by 37.9% (47 women) of the patients and for possible depression disorder by 19.5% (24 women). The most common menstrual associated symptoms were heavy menstrual bleeding (80.6%), dysmenorrhea (55.6%), and irregular menstrual cycles (33.9%). More women with AUB in our study had anxiety as measured by the K-BAI and depression as measured by the K-BDI-II than general Korean population. A history of abortion and cesarean section (C/sec) were related with anxiety, whereas a history of minor surgery was related to depression. Anxiety and depression (r = 0.629, P < 0.001) were correlated with AUB. According to age, variable factors affect anxiety (history of abortion, history of C/sec, minor surgery, Body mass index [BMI], history of OCs) and depression (BMI ≥ 25, history of minor surgery). We have found that anxiety and depression seem to be underestimated in Korean women with AUB symptoms. The relationship between the development of anxiety and depression with variable factors are unknown and therefore, further study is needed to clarify and understand the effects of AUB. To improve the health of women with AUB, screening for mental health issues is needed for early detection and treatment of anxiety and depression.

A set of variables including mobile banking (MB), internet banking (IB), and implementation degree of ATMs functions as a proxy for service delivery technology.

The research results indicate that there is a significant positive impact of mobile banking (MB) and online banking (IB) on bank performance. In addition, this study has not found an impact on ATM implementation for bank performance.
Differential expression of MAM domain containing 2 in cancers of the breast.
Authors: Mamoor Shahan
Published: April 2021

Breast cancer affects women at relatively high frequency (1). We mined published microarray datasets (2, 3) to determine in an unbiased fashion and at the systems level genes most differentially expressed in the primary tumors of patients with breast cancer. We report here significant differential expression of the gene encoding MAM domain containing 2, MAMDC2, when comparing primary tumors of the breast to the tissue of origin, the normal breast. MAMDC2 was also differentially expressed in the tumor cells of patients with triple negative breast cancer. MAMDC2 mRNA was present at significantly lower quantities in tumors of the breast as compared to normal breast tissue. Analysis of human survival data revealed that expression of MAMDC2 in primary tumors of the breast was correlated with distant metastasis-free survival in patients with HER2+ subtype cancer, demonstrating a relationship between primary tumor expression of a differentially expressed gene and patient survival outcomes influenced by molecular subtype. MAMDC2 may be of relevance to initiation, maintenance or progression of cancers of the female breast.

Profesi sudah pasti pekerjaan tetapi tidak semua pekerjaan bisa disebut profesi. Profesi bisa digolongkan sebagai pekerjaan yang memerlukan keahlian dan lisensi pada bidangnya, mengabdi tanpa paksaan serta memiliki kode etik profesi. Pekerjaan tidak memerlukan keahlian atau lisensi dalam pekerjaannya berbeda dengan profesi yang menyangkut pengabdian disertai keahlian untuk melayani klien atau masyarakat. Guru memiliki tugas untuk mengajar dan membimbing peserta didik karena itulah pengabdian guru sangat menentukan masa depan bangsa. Kualitas profesional guru pun menjadi faktor penting untuk menaikkan kualitas pendidikan yang masih kurang merata di negeri ini. Dengan tugas menentukan nasib masa depan bangsa maka guru dituntut memiliki kompetensi untuk melaksanakan tugasnya. Terdapat empat kompetensi yang harus dimiliki seorang guru dalam undang-undang yaitu kompetensi profesional, kompetensi pedagogi, kompetensi sosial serta kompetensi kepribadian.

Profesi merupakan suatu pengertian yang bersifat legal-formal memiliki aturan-aturan (kode etik) tersendiri untuk menjadi acuan baku dalam melaksanakan programnya, dimaknai tidak sebagai bidang usaha yang berorientasi pada profit dan kepentingan pragmatis bahkan sekedar karir. Profesi guru merupakan profesi yang dapat menentukan masa depan bangsa ini. Guru harus menguasai strategi pembelajaran, mendorong siswa belajar untuk mencapai prestasi yang tinggi maka, segala upaya peningkatan kualitas pendidikan akan mencapai hasil yang maksimal. Indonesia merupakan negara yang masih saja berkembang, termasuk juga dengan kualiatas pendidikan masih saja memasuki peringkat bawah, hal ini disebabkan kurangnya guru yang profesional dalam melaksanakan peran, hak, serta kewajibanya sebagai guru. Oleh karena itu sebagai seorang guru harusnya melaksanakan apa-apa saja harus ditaati sebagai tenaga profesi. kemampuan yang harus dimiliki seorang profesi guru yaitu menguasai materi, struktur, konsep, dan pola pikir keilmuan yang mendukung mata pelajaran yang diampu, memanfaatkan teknologi informasi dan komunikasi untuk berkomunikasi dan mengembangkan diri.

Are there non-linear relationships between alcohol consumption and long-term health?: A systematic review of observational studies employing approaches to improve causal inference
Authors: Visontay Rachel , Sunderland Matthew , Slade Tim , Wilson Jack , Mewton Louise
Published: April 2021

Research has long found ‘J-shaped’ relationships between alcohol consumption and certain health outcomes, indicating a protective effect of moderate consumption. However, methodological limitations in most studies hinder causal inference. This review aimed to identify all observational studies employing improved approaches to mitigate confounding in characterizing alcohol–long-term health relationships, and to qualitatively synthesize their findings (PROSPERO registration: CRD42020185861). Eligible studies met the above description, were longitudinal (with pre-defined exceptions), discretized alcohol consumption, and were conducted with human populations. MEDLINE, PsycINFO, Embase and SCOPUS were searched in May 2020, yielding 16 published manuscripts reporting on cancer, diabetes, dementia, mental health, cardiovascular health, mortality, HIV seroconversion, and musculoskeletal health. Risk of bias of cohort studies was evaluated using the Newcastle Ottawa Scale, and a recently developed tool was used for Mendelian Randomization studies. A variety of functional forms were found, including reverse J/J-shaped relationships for prostate cancer and related mortality, dementia risk, mental health, and certain lipids. However, most outcomes were only evaluated by a single study, and few studies provided information on the role of alcohol consumption pattern. More research employing enhanced causal inference methods is urgently required to accurately characterize alcohol–long term health relationships.
Changes in tissue composition and load response after transtibial amputation indicate biomechanical adaptation

Published: April 2021

Despite the potential for biomechanical conditioning with prosthetic use, the soft tissues of residual limbs following lower-limb amputation are vulnerable to damage. Imaging studies revealing morphological changes in these soft tissues have not distinguished between superficial and intramuscular adipose distribution, despite the recognition that intramuscular fat levels indicate reduced tolerance to mechanical loading. Furthermore, it is unclear how these changes may alter tissue tone and stiffness. This study was designed to compare the morphology and biomechanical response of limb tissues to mechanical loading in individuals with and without transtibial amputation, using magnetic resonance imaging in combination with tissue structural stiffness. The results revealed higher adipose infiltrating muscle in residual limbs than in intact limbs (residual: median 2.5% (range 0.2-8.9%); contralateral: 1.7% (0.1-5.1%); control: 0.9% (0.4-1.3%)), indicating muscle atrophy and adaptation post-amputation. The intramuscular adipose content correlated negatively with daily socket use, although there was no association with time post-amputation. Residual limbs were significantly stiffer than intact limbs at the patellar tendon site, which plays a key role in load transfer across the limb-prosthesis interface. The tissue changes following amputation can have relevance in the clinical understanding of prosthetic socket design variables and soft tissue damage risk in this vulnerable group.
Preference Falsification: How Social Conformity as an Interdependent, Recursive, and Multilevel Process Corrupts Public Knowledge
Authors: Elder Jacob , Derreumaux Yrian , Hughes Brent
Published: April 2021

Throughout life, people often misrepresent their preferences to maintain social harmony, yet the cumulative effects of individual acts of conformity on society are largely underexplored. This phenomenon is captured by the economic theoretical framework of Preference Falsification, which describes why people misrepresent their preferences in the face of social pressures, and how misrepresentation accumulates to broader misunderstandings that can fuel political polarization. We first describe why the current political climate may foster motivations to misrepresent preferences, as individuals are increasingly strongly identified with their political groups and siloed into like-minded communities with strong pressures to conform to group norms. Next, we adopt a psychological lens to understand Preference Falsification at different levels of analysis: (1) at the individual level, to examine how failures in cognitive empathy and statistical learning facilitate social conformity that gives rise to falsification, and (2) at the collective level, to examine how misrepresented preferences propagate across social relationships and structures. Our goal is to advance theory by demonstrating that Preference Falsification provides a generative framework that describes how various micro-level phenomena related to social influence can propagate across social structures and corrupt public knowledge. Ultimately, we argue that PF limits access to accurate and truthful information, which fuels misinformation and poses a barrier to social change.

The logic from Pujon Kidul village, towards village elites who have succeeded in developing tourism with village local products by empowering local communities needs to be studied continuously. This study aims to determine the Logic of Village Elite in Pujon Kidul Tourism Village Development Practices. This research uses a qualitative approach and descriptive research type, through field observations, interviews and documentation of informants. The theory used in this research is Pierre Bourdieu's theory of the practice of habitus. In 2015, the elite of Pujon Kidul village succeeded in building a rice field cafe, a tourist village in Tulungrejo, and developing in the field of educational tourism, until now they have succeeded in building the Pujon Kidul Tourism Village. Keywords: Elite, Tourism Village Development, and Community Empowerment.
The Association Between Oldest Son Status and Co-Residence with Parents Across Periods and Cohorts in South Korea
Authors: Yoo Jaeeon , Russell Daniel Wayne
Published: April 2021

To explore patriarchal kinship structure centered on the oldest son across cohorts and time periods, this study compares intergenerational co-residence in the Korean War after Liberation Day (KWALD) cohort and the Korean Baby Boomer (KBB) cohort in 2006 and 2014. Participants are 1,763 KLoSA respondents born between 1945 and 1962 who participated in the Korean Longitudinal Study of Aging survey in both 2006 and 2014 and had living parents at both waves of the survey. Using multiple group analyses the results show that the pattern of the patriarchal kinship structure based on the oldest son status tends to remain in both the KWALD and KBB cohorts. However, in the KBB cohort the family structure based on the oldest son status was weakened in 2014 compared to 2006. These results have implications for the social norms that influence family structure in later life by time period and cohort.
Against Using the Book Proposal to Rethink Your Book: Why and How to Work on Your Book Instead
Authors: Knox Katelyn E.
Published: April 2021

Drawing from personal experience revising my dissertation into a book and helping dozens of authors do the same, I put language to a critical yet challenging phase in this process: working on one’s book. After describing what working on one’s book entails, elucidating how it fundamentally differs in posture from writing a book proposal, and explaining why authors might abandon this work prematurely in favour of more familiar modes of working, I offer actionable prompts and exercises that authors can use to make working on their book more concrete.
Modelamento computacional das transformações de fase durante os ciclos térmicos de processamento de um aço inoxidável superdúplex

This project aims to perform the computer simulation of the transformation’s kinetics and phase evolution during the thermal processing cycles of a superduplex stainless steel, considering the stages of heating, hot working and cooling, using DICTRA® software. The input data for the simulations were chemical composition and phase size, desired simulation temperature, and heating and cooling rates when necessary to describe the thermal cycle. TCFE9 thermodynamic database and MOBFE4 atomic mobility database were used in order to obtain results for different models, determining the one that best describes the phase transformation kinetics. Different rates were simulated during the heating of the material from 950 ° C, considering the initial microstructural condition of 50% of ferrite [alpha] and 50% austenite [gamma], up to 1250 ° C, typical forming temperature. In heating, a maximum fraction of 66.6% [alpha] was obtained at a rate of 0.30 ° C/s, [alpha] value close to the 70% expected by the equilibrium simulation in Thermocalc®. After 1000 s of plateau at 1250 ° C and cooling to the solubilization temperature, 1090 ° C, at the rate of 0.30 ° C/s, the fraction of [alpha] reduced to values of 58.7%. In the sequence, different cooling rates were also simulated with or without the presence of solubilizations plateau. Considering 3600 s of plateau at 1090 ° C, it was possible to recover the desired duplex condition, reaching 55.5% [alpha], but not reaching the 50% expected by the equilibrium balance, since there is still a composition gradient in [alpha] and [gamma] by DICTRA® simulations. Seeking the maintenance of the duplex microstructure, a cooling was performed from 1090 °C to 790 ° C at a critical rate of 3.0 ° C/s, obtaining volumetric fractions of 56% [alpha], 43% [gamma] and sigma fractions equal to or less than 1%. If the plateau at 1090 ° C was not considered, that is, promoting cooling from 1250 °C, where the condition of 58.7% [alpha] was reached, to 790 ° C at the rate of 3.0 ° C/s volumetric fractions of 59.6% alpha], 39.4% [gamma] and 0.9% [sigma] were obtained. DICTRA® was unable to simulate the precipitation of chromium nitrides (Cr2N) during cooling, either because there was no nitrogen supersaturation (N) in [alpha] or because it was unable to predict this supersaturation. From the results of kinetics and evolution of the phases’ volumetric fraction obtained in the thermal cycle of steel processing UNS S32750, it was possible to obtain the computational model that best describes the real behavior of the studied steel

We present the development of an interferometer capable of making contactless measurements of vibrations. The resultsshow the we achieve micro- and/or nano-metric measurements without the stabilization of the laser. While there aremultiple techniques to achieve this objective, in this case we use a method whose main virtue is the low componentcount and the self-alignment capacity. The method is based on the optical feedback effect in a laser diode which relieson the use of an internal reference for calibration.

One of the most important reactions for electrochemical science and technology is the electrocatalytic reduction ofoxygen. It is particularly relevant in fuel cells because it is slow to react and requires high overpotentials. This workaims to study electrodes with deposits of Au on Ti obtained by electrodeposition. The substrates have undergone po-tentiodynamic growths of oxides before deposition for some electrodes and after deposition for other electrodes understudy, at different final potentials. Both procedures resulted in the formation of a composite Au layer on the Ti surface.The electrochemical behavior of these composite layers was examined in a 0.01 M HClO4solution, both oxygen-freeand oxygen-saturated, and compared with the behavior of Ti as a target, using the cyclic voltammetry technique. In thepotential region of the oxygen reduction reaction (RRO), the Au layer on the Ti obtained by first performing the Audeposition and then the growth of the anode oxide showed a better response, not only in the onset potential of the RRO,but also in the current densities. In all cases the voltammetry curves of the Au and TiO2 composite layers were similarto those shown by the Au polycrystalline.
Douleur et souffrance : représentations croisées des oncologues et des patients, une étude qualitative
Authors: Salès-Wuillemin E. , Lejeune C. , Clain A. , Carrel T. , Dolard A.
Published: April 2021

Nous mesurons la place de la douleur et de la souffrance dans la représentation du cancer de patients et d’oncologues. Dans l’univers sémantique des patients, la souffrance renvoie à la dégradation du corps et à la vulnérabilité ; la douleur concrétise la maladie et son diagnostic. La souffrance n’est pas évoquée par les oncologues. Pour eux, la douleur est un signe d’évolution de la maladie et un indicateur de la tolérance aux traitements. Au cœur de la relation thérapeutique, l’étude apporte des éléments de réflexion sur l’intercompréhension médecin–patient.

Introduction : À l’heure actuelle, le retentissement des cancers utérins, ainsi que leur traitement sur l’image du corps, demeure un sujet peu étudié en Tunisie et souvent négligé aussi bien par les praticiens, les malades et leurs partenaires.

Méthodes : Il s’agit d’une étude transversale descriptive colligeant 100 patientes tunisiennes suivies à l’institut Salah- Azaïez pour un cancer de l’endomètre ou du col utérin confirmés histologiquement et non métastatiques, avec un recul supérieur à six mois. Nous avons utilisé l’échelle Body Image Scale (BIS) et Female Sexual Function Index (FSFI). Nous avons collecté les antécédents personnels et familiaux, et différentes données sociodémographiques des patientes.

Résultats : Dans notre étude, 40 % des patientes ont des troubles de l’image du corps. La moyenne du score BIS était de 12,03 avec des extrêmes allant de 0 à 30 avec un écarttype de 7,88. En analyse univariée, l’absence du soutien familial, l’altération de la relation de couple et de la relation sexuelle, la mauvaise tolérance de la chirurgie et la curiethérapie utérovaginale étaient significativement associées à l’altération de l’image corporelle. En analyse multivariée, le bas niveau socio-économique était le facteur indépendant protecteur du trouble de l’image du corps, et la dysfonction sexuelle était le facteur indépendant prédicteur de ce trouble.

Conclusions : Le manque de communication des patientes avec leur conjoint et avec l’équipe de soin constitue l’un des principaux obstacles lorsqu’il s’agit de reconnaître et de traiter ce problème. Des stratégies préventives visant à maintenir une image corporelle positive chez ces femmes devraient être entreprises.
Covid-19, une remise en question des fondamentaux de la logistique et du SCM ?
Authors: Fabbe-Costes Nathalie , Sépari Sabine
Published: April 2021

La crise Covid-19 a confirmé le caractère stratégique de la logistique et du supply chain management (SCM) mais a aussi conduit à en critiquer certains aspects. Cette crise, inédite à bien des égards, remet-elle en question les travaux réalisés jusqu’à présent en logistique et SCM ? Les auteurs tentent, à partir d’une relecture critique du numéro spécial RFG n° 277/2018 « Le supply chain management. Décloisonner pour créer de la valeur », de dégager une réponse à la lumière des premiers enseignements tirés de la crise Covid-19. Si les fondamentaux ne semblent pas remis en question, de nouvelles pistes sont à développer ou explorer.

Published: April 2021

La crise du Covid-19 crée une rupture sur le plan spatial et temporel. Pour « être seuls ensemble » lors du confinement, les individus se retrouvent dans des communautés en ligne. Dans ce contexte d’urgence sanitaire émerge des communautés de crise au sein desquelles il est possible d’identifier des caractéristiques propres. Éphémères et basées sur l’improvisation, elles sont ouvertes au plus grand nombre et à la diversité des participants, et se construisent sur des motivations sociétales de façon rapide avec une grande créativité dans les productions.
