RESUMO

BACKGROUND: The acute nature of the COVID-19 pandemic has put a strain on health resources that are usually dedicated to chronic illnesses. Resulting changes in care practices and networks have had major repercussions on the experience of people with chronic disorders. OBJECTIVE: This paper presents the protocol of the Parcours, Associations, Réseau, Chronicité, Organisation, Usagers, Retour d'expérience, Soins (PARCOURS)-COVID study. The aim of this study is to evaluate the effects of reorganization of the health system on the usual care network of patients with chronic illness, which fosters and qualifies the quality and continuum of care provided. The first objective of this study is to document these patients' experiences through transformations and adaptations of their network, both in the practical dimension (ie, daily life and care) and subjective dimension (ie, psychosocial experience of illness and relationship to the health system). The second objective of the study is to understand and acknowledge these reorganizations during the COVID-19 lockdown and postlockdown periods. The third objective is to produce better adapted recommendations for patients with chronic illness and value their experience for the management of future health crisis. METHODS: The PARCOURS-COVID study is a qualitative and participatory research involving patient organizations as research partners and members of these organizations as part of the research team. Three group of chronic diseases have been selected regarding the specificities of the care network they mobilize: (1) cystic fibrosis and kidney disease, (2) hemophilia, and (3) mental health disorders. Four consecutive phases will be conducted, including (1) preparatory interviews with medical or associative actors of each pathology field; (2) in-depth individual interviews with patients of each pathology, analyzed using the qualitative method of thematic analysis; (3) results of both these phases will then be triangulated through interviews with members of each patient's care ecosystem; and finally, (4) focus groups will be organized to discuss the results with research participants (ie, representatives of chronic disease associations; patients; and actors of the medical, psychosocial, and family care network) in a research-action framework. RESULTS: The protocol study has undergone a peer review by the French National Research Agency's scientific committee and has been approved by the research ethical committee of the University of Paris (registration number: IRB 00012020-59, June 28, 2020). The project received funding from August 2020 through April 2021. Expected results will be disseminated in 2021 and 2022. CONCLUSIONS: Our findings will better inform the stakes of the current health crisis on the management of patients with chronic illness and, more broadly, any future crisis for a population deemed to be at risk. They will also improve health democracy by supporting better transferability of knowledge between the scientific and citizen communities.

RESUMO

Abstract The purpose of this article is to describe the subjective experience of the diagnosis of Attention Deficit and Hyperactivity Disorder (ADHD) and the cultural meanings that shape this experience. Based on interviews and discussion groups with diagnosed people and their families in Chile and France, this article show that ADHD can acquire multiple meanings. From a thematic analysis, we identified three registers or ways of living and thinking about ADHD. In the deficit register, the disorder is experienced primarily as a failure of certain abilities. In the disruption register, the disorder is experienced as disrupting the person's life, personality and interactions, which must then be normalized. In the register of hidden potential, on which this article focuses, ADHD is simultaneously thought of as a difficult and valuable condition, a source of exceptional capacities that are often hidden in the ordinary functioning of social life. We therefore invite reflection that identifies the factors of mobilization or non-mobilization of the hidden potential register, with particular emphasis not only on relational configurations, socio-economic variables, and the gender variable, but also on the institutional and political context of each country.


Resumo O objetivo deste artigo é descrever a experiência subjetiva do diagnóstico de Transtorno do Déficit de Atenção com Hiperatividade (TDAH) e os significados culturais que moldam essa experiência. Com base em entrevistas e grupos de discussão com pessoas diagnosticadas e suas famílias no Chile e na França, este artigo demonstra que diversos significados podem ser atribuídos ao TDAH. A partir de análise temática, foram identificados três registros ou modos de viver e pensar TDAH. No registro déficit, o transtorno é vivenciado primariamente como falha de certas habilidades. No registro distúrbio, o transtorno é vivenciado como uma perturbação da vida pessoal, personalidade e interações que necessita ser normalizada. No registro de potencial oculto, foco deste artigo, TDAH é considerado simultaneamente condição difícil e valiosa, fonte de capacidades excepcionais que estão habitualmente ocultas no andamento comum da vida social. Portanto, propõe-se refletir e identificar os fatores de mobilização e não mobilização do registro de potencial oculto, com particular ênfase não só nas configurações relacionais, variáveis socioeconômicas e de gênero, mas também no contexto institucional e político de cada país.

RESUMO

BACKGROUND: Venous thrombosis is a serious complication of combined contraceptive usage. However, mesenteric venous thrombosis and intestinal necrosis are infrequently seen in women using oral contraceptives, and in such cases diagnosis is often delayed. CASE PRESENTATION: We report the case of a 38-year-old obese female patient who presented with acute abdominal pain. A bowel infection was first diagnosed and treated with antibiotics. Contrast-enhanced tomography of the abdomen revealed diffuse ischemia of the small intestine with superior mesenteric thrombosis. Laparotomy with segmental resection of both small and large bowel was performed. No predisposing factor of mesenteric venous thrombosis was demonstrated except association of the combined contraceptive with obesity. CONCLUSION: This report highlights the need for clinicians to suspect venous mesenteric thrombosis in women of reproductive age with acute abdominal pain and poor physical findings. Detailed personal history including prescriptions should help to quickly and accurately determine the problem.

RESUMO

Lymphatic dissemination is a key event in cervical cancer progression and related tumor lymphatic markers are viewed as promising prognostic factor of nodal extension. However, validating such parameters requires an objective characterization of the lymphatic vasculature. Here, we performed a global analysis of the lymphatic network using a new computerized method applied on whole uterine cervical digital images. Sixty-eight cases of cervical neoplasia (12 CIN3, 10 FIGO stage 1A and 46 stage IB1) and 10 cases of normal cervical tissue were reacted with antibodies raised against D2-40, D2-40/p16 and D2-40/Ki67. Immunostained structures were automatically detected on whole slides. The lymphatic vessel density (D2-40), proliferating lymphatic vessel density (D2-40/ki67) and spatial lymphatic distribution in respect to the adjacent epithelium were assessed from normal cervix to early cervical cancer and correlated with lymphovascular space invasion and lymph node status. Prominent lymphatic vessel density and proliferating lymphatic vessel density are detected under the transformation zone of benign cervix and no further increase is noted during cancer progression. Notably, a shift of lymphatic vessel distribution toward the neoplastic edges is detected. In IB1 cervical cancer, although intra- and peritumoral lymphatic vessel density are neither correlated with lymphovascular space invasion nor with lymph node metastasis, a specific spatial distribution with more lymphatic vessels in the vicinity of tumor edges is predictive of lymphatic dissemination. Herein, we provide a new computerized method suitable for an innovative detailed analysis of the lymphatic network. We show that the transformation zone of the benign cervix acts as a baseline lymphangiogenic niche before the initiation of neoplastic process. During cancer progression, this specific microenvironment is maintained with lymphatic vessels even in closer vicinity to tumor cells.

RESUMO

In a prospective, randomized clinical study 77 women were assigned randomly to receive sequential hormone therapy with either conventional oral conjugated equine estrogens (0.625 mg) with the addition on 14 of the 28 days of oral medroxyprogesterone acetate (5 mg) or natural E(2) gel (1.5 mg) with oral micronized P (200 mg) on 14 of the 28 days of each cycle. Because oral conjugated equine estrogens-medroxyprogesterone acetate induced a highly significant increase in breast cell proliferation in contrast to percutaneous E(2)-oral P with a difference between therapies approaching significance, the former therapy has a marked impact on the breast whereas natural percutaneous E(2)-oral micronized P has not.

RESUMO

BACKGROUND: Levonorgestrel-releasing intrauterine system (LNG-IUS), although inserted to reduce heavy menstruation, causes irregular early transient bleeding. The objective of the study was to document quantitative changes in endometrial vessels of short- (< or =3 months) and long-term (> or =12 months) LNG users. The area, density and maturation of endometrial vessels were quantified in 19 endometrial biopsies of women with LNG-IUS and in 10 normally ovulating patients during mid-luteal phase. METHODS: Vessel maturation was evaluated by double immunostaining using anti-von Willebrand factor (endothelial cell marker) and anti-alpha Smooth Muscle Actin (vascular smooth muscle cells) antibodies. Vessel area, number and density were quantified with a novel computer-assisted image analysis system. RESULTS: Endometrium exposed to LNG-IUS for 1-3 months displayed a 11.5-fold increase in small naked vessel number. The partially mature vessel (alphaSMA partially positive) number increased six times. After long-term LNG-IUS treatment, the immature and partially mature vessel number remained four times higher than in the control group. Vessel area and density also increased dramatically in a time-dependent pattern with LNG-IUS use. CONCLUSIONS: Levonorgestrel affects blood vessel number, area, density and maturation in a time-dependent pattern that may explain the early transient increase in breakthrough bleeding with the LNG-IUS.

RESUMO

OBJECTIVE: To evaluate whether endometriosis could be related to an impaired balance between apoptosis and proliferation, two processes which could be modulated by hormonal status. DESIGN: Immunohistochemical study. SETTING: Academic research laboratory. INTERVENTION(S): Endometriotic samples obtained from peritoneum of women aged 26-40 years who were undergoing laparoscopy for pain or infertility. MAIN OUTCOME MEASURE(S): Apoptotic cells were detected with the use of the terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) assay. The production of p53 and bcl-2, estrogen and Progesterone (P) receptors, and cellular proliferation were assessed by immunohistochemistry in eutopic and ectopic endometria from 30 patients with endometriosis throughout the menstrual cycle. Results were compared with those from normal endometria from 15 fertile patients. RESULT(S): Endometriotic lesions were characterized by reduced TUNEL and p53 stainings and by enhanced bcl-2 staining. No correlation between apoptosis and estrogen receptor or P receptor levels was found. A lower amount of steroid receptor was found in endometriotic tissues, without cyclic modulation, compared with the eutopic endometrium. CONCLUSION(S): Our results suggest that when endometrial tissue is located at ectopic locations, it differs from eutopic endometrium by its proliferation rate, steroid hormone levels, and markers of apoptosis. A reduced sensitivity of endometriotic cells to apoptosis could promote the dissemination and implantation of these cells to ectopic sites.

RESUMO

PURPOSE: Infection with oncogenic human papillomavirus (HPV) and HPV-16 in particular is a leading cause of anogenital neoplasia. High-grade intraepithelial lesions require treatment because of their potential to progress to invasive cancer. Numerous preclinical studies have demonstrated the therapeutic potential of E7-directed vaccination strategies in mice tumour models. In the present study, we tested the immunogenicity of a fusion protein (PD-E7) comprising a mutated HPV-16 E7 linked to the first 108 amino acids of Haemophilus influenzae protein D, formulated in the GlaxoSmithKline Biologicals adjuvant AS02B, in patients bearing oncogenic HPV-positive cervical intraepithelial neoplasia (CIN). METHODS: Seven patients, five with a CIN3 and two with a CIN1, received three intramuscular injections of adjuvanted PD-E7 at 2-week intervals. Three additional CIN1 patients received a placebo. CIN3 patients underwent conization 8 weeks postvaccination. Cytokine flow cytometry and ELISA were used to monitor antigen-specific cellular and antibody responses from blood taken before and after vaccine or placebo injection. RESULTS: Some patients had preexisting systemic IFN-gamma CD4+ (1/10) and CD8+ (5/10) responses to PD-E7. Vaccination, not placebo injection, elicited systemic specific immune responses in the majority of the patients. Five vaccinated patients (71%) showed significantly increased IFN-gamma CD8+ cell responses upon PD-E7 stimulation. Two responding patients generated long-term T-cell immunity toward the vaccine antigen and E7 as well as a weak H. influenzae protein D (PD)-directed CD4+ response. All the vaccinated patients, but not the placebo, made significant E7- and PD-specific IgG. CONCLUSIONS: The encouraging results obtained from this study performed on a limited number of subjects justify further analysis of the efficacy of the PD-E7/AS02B vaccine in CIN patients.

RESUMO

The cyclic growth, differentiation, and cell death of endometrium represents the most dynamic example of steroid-driven tissue turnover in human adults. Key effectors in these processes-matrix metalloproteinases (MMPs) and their specific inhibitors (TIMPs)-are regulated by ovarian steroids and, locally, by cytokines. We used reverse transcription-polymerase chain reaction to evaluate the expression of both transcriptionally regulated molecules such as estrogen receptor-alpha, progesterone receptor, and prolactin and a large array of MMPs and TIMPs (MMP-1, -2, -3, -7, -8, -9, -11, -12, -19, -26, MT1-MMP, MT2-MMP, MT3-MMP, TIMP-1, -2, -3). Altogether, three distinct patterns of MMP and two patterns of TIMP expression were detected in cycling endometrium: 1). MMPs restricted to the menstrual period (MMPs-1, -3, -8, -9, -12); 2). MMPs and TIMPs expressed throughout the cycle (MMP-2, MT1-MMP, MT2-MMP, MMP-19, TIMP-1, and TIMP-2); 3). MMPs predominantly expressed during the proliferative phase (MMP-7, MMP-11, MMP-26, and MT3-MMP); and 4). TIMP-3, which, contrary to the other TIMPs, shows significant modulations, with maximum expression during the late secretory and menstrual phases. These specific patterns of MMP expression associated with each phase of the cycle may point to specific roles in the processes of menstruation, housekeeping activities, angiogenesis, tissue growth, and extracellular matrix remodeling.

RESUMO

OBJECTIVE: To evaluate, in a new original in vitro assay, putative factors that could modulate the adhesion of endometrial cells to peritoneum. DESIGN: Prospective, controlled in vitro study. SETTING: Academic research laboratory. PATIENT(S): Fourteen nonmenopausal women undergoing hysterectomy or laparoscopy for benign gynecologic indication. INTERVENTION(S): Endometrial cells obtained from women with regular cycles without endometriosis were labeled with 111Indium and confronted in vitro with mouse peritoneum in the presence of various cytokines and/or antiadhesive compounds. MAIN OUTCOME MEASURE(S): Radioactivity in 111Indium-labeled endometrial cells. RESULT(S): The adhesion of human endometrial cells to mouse peritoneum was increased by treatment with pro-inflammatory cytokines (interleukin IL-1beta, IL-6, TNF alpha, TGF-beta1). Whereas heparan sulfate had no effect on cell adhesion, a gel of ferric hyaluronate (Intergel) was able to counteract the pro-adhesive effect of cytokines. Interestingly, the pretreatment of peritoneum with cytokines, 24 hours before cell seeding in the presence of the ferric hyaluronate gel, restored the cytokine-promoting effect on cell adhesion. CONCLUSION(S): Proinflammatory cytokines promote the in vitro peritoneal adhesion of endometrial cells. An antiadhesive hyaluronate gel used in clinics decreases the adhesion in a dose-dependent manner and reduces cytokine bioavailability.

RESUMO

OBJECTIVE: To investigate the role of different cellular types (epithelial and stromal endometrial cells and peritoneal cells) in the ectopic implantation of endometrium and to evaluate the importance of endocrine environment on the adhesion of endometrial cells to the peritoneum. DESIGN: Experimental prospective study. SETTING: University hospital, department of cell biology. ANIMAL(S): One hundred one nude mice. INTERVENTION(S): Monolayer culture of human epithelial and stromal endometrial cells obtained from patients undergoing hysterectomy or laparoscopy for benign disease. Intraperitoneal injection of cells into nude mice. MAIN OUTCOME MEASURE(S): Two weeks after cell injection, adhesion of endometrial cells was evaluated by histological and immunohistochemical examination. RESULT(S): Mixed cultures of stromal and epithelial cells, but not purified epithelial or stromal cells alone, adhered to the mouse peritoneum and led to endometriotic-like nodules. Pretreatment of cells with estrogen alone or with estrogen and progestin resulted in a higher percentage of animals developing endometriotic-like nodules, whereas treatment with progestin alone did not affect endometriotic implantation. CONCLUSION(S): Our data indicate that the success of endometrial cell implantation is dependent on the cooperativeness between stromal and epithelial endometrial cells, as well as on the endocrine environment of endometrial cells, but not that of recipient animals. The results emphasize the role of both endometrial cell types for ectopic implantation.
