RESUMO
OBJECTIVES: To address global aging, a paradigm shift is needed from disease prevention and treatment towards active aging, i.e., optimizing opportunities for health, participation, and security as people age. Little is known about how age-friendly environments promote active aging. This study thus aimed to explore how (through which mechanisms and in what contexts) environments can promote active aging and, specifically, positive health, social participation, and health equity. METHODS: Using a realist approach and semi-structured focus groups, a case study was used in two Quebec municipalities known for best fostering active aging. Data also included participants' logbooks, sociodemographic questionnaires, municipalities' sociodemographic profiles, and policy documents. A conceptual framework and thematic content analysis were carried out. RESULTS: A total of 24 participants (9 older adults, 4 health professionals, 3 community-based actors, 5 municipal employees, and 3 elected officials) took part in 5 focus groups. Regarding contexts, both cases were midsize municipalities having an income and education level higher to Quebec's averages with supportive active aging policies. Two main themes explained how the environments promoted active aging: (1) by ensuring proximity through built (urban planning), social (network structures), services (variety and availability of local and outreach resources), and organizational (active listening to older adults' needs for active aging) environments; and (2) by fostering transversality through built (universal accessibility, intergenerational spaces), social (intergenerational opportunities for social participation), and political/organizational (unified and complementary policies) environments. CONCLUSION: To better promote active aging through age-friendly environments, practices should focus on fostering proximity and transversality, and act simultaneously on multiple environments.
RéSUMé: OBJECTIFS: Pour faire face au vieillissement des populations, un changement de paradigme est requis allant de la prévention et du traitement de la maladie vers la promotion d'un vieillissement actif, c.-à.-d. l'optimisation des possibilités de bonne santé, de participation sociale et de sécurité pendant l'avancement de l'âge. Peu d'informations renseignent sur comment les environnements favorisent le vieillissement actif. Cette étude visait donc à explorer comment (par quels mécanismes et dans quels contextes) les environnements favorisent le vieillissement actif et, spécifiquement, la santé positive, la participation sociale et l'équité en santé des aînés. MéTHODES: Selon une approche réaliste et des groupes de discussion semi-dirigés, une étude de cas multiples a été réalisée dans deux municipalités québécoises, reconnues pour favoriser un vieillissement actif. Les données incluaient aussi les journaux de bord et les questionnaires sociodémographiques des participants ainsi que les profils sociodémographiques des municipalités et leurs politiques municipales. Les données ont été traitées à l'aide d'un cadre conceptuel et d'une analyse de contenu thématique. RéSULTATS: Un total de 24 participants (9 aînés âgés de 65 ans ou plus, 4 professionnels de la santé, 3 acteurs communautaires, 5 employés municipaux et 3 élus) ont pris part à un des cinq groupes de discussion. Concernant les éléments de contexte, les deux municipalités étaient de taille moyenne et présentaient des revenus et un niveau de scolarité supérieurs à la moyenne québécoise ainsi que des politiques municipales favorisant un vieillissement actif. Deux thèmes principaux expliquaient comment les environnements favorisaient le vieillissement actif : 1) en assurant la proximité des environnements bâti (aménagement urbain), social (structures des réseaux sociaux), des services (ressources locales et de proximité) et politique/organisationnel (écoute active des besoins des aînés pour un vieillissement actif); et 2) en favorisant la transversalité des environnements bâti (accessibilité universelle, espaces intergénérationnels), social (opportunités intergénérationnelles) et politique/organisationnel (politiques unifiées et complémentaires). CONCLUSION: Pour mieux promouvoir le vieillissement actif grâce à des environnements conviviaux aux aînés, les pratiques doivent privilégier la proximité et les approches transversales, en plus d'agir sur plusieurs environnements simultanément.

Much of the literature on fertility intentions has shown that they are broadly predictive of fertility behaviour. Fertility intentions tend to change over a person's life. How religiosity affects these changes over time has rarely been the subject of investigation. In this paper, we focus on whether and how religiosity affects trajectories of lifetime fertility intentions. Specifically, we examine whether highly religious people start with higher fertility intentions and are more likely to sustain them during their life course compared to their less religious counterparts. We apply random and fixed effects growth curve models to data from the German family panel pairfam, using a sample of 6214 women and 5802 men aged 14-46. We find that religiosity mainly contributes to explain the starting level at teenage years but not the trajectories of lifetime fertility intentions as people get older. Highly religious people start with higher intentions than less religious people. However, similarly to less religious people they experience a decline in their fertility intentions with age. This study demonstrates that religiosity is an important variable in research on fertility intentions but with changing relevance over the life course.

PURPOSE: The number of endothelial grafts precut by eye banks increases. Their shelf life is limited to a few days. We previously demonstrated the superiority of an active storage machine (ASM) over organ culture (passive) for whole corneas. AIMS: to measure endothelial viability of precut DSAEK after 3 or 10 days of storage in our ASM in a preclinical study. METHODS: Human pairs of corneas were included. The endothelial cell density (ECD in cells/mm2), and central corneal thickness (CCT in µm) were measured to ensure their initial intra pair comparability. After deswelling (CorneaJet, Eurobio) grafts preparation was performed by cutting the anterior stroma with a Moria linear microkeratome and keeping the anterior lamellae attached during storage. After randomization, one cornea was kept in the corneajet bottle (CJ) and the other was inserted into the ASM allowing a renewal or storage medium (CorneaMax, Eurobio) at 2.6 µL/min with 21 mmHg of pressure in the endothelial chamber. Both group of corneas were stored for 3 or 10 days at 31°C. The final viable ECD (vECD) was determined using the triple staining with Hoechst-Ethidium-Calcein-AM by an independent experimenter in a masked fashion. RESULTS: Initial ECDs were comparable: 2595±878 in ASM versus 2654±954 cells/mm2 in CJ for the 3-days period (n=5 pairs) and 2416±712 in ASM versus 2492±764 cells/mm2 in CJ for the 10-period (n=5 pairs). CCTs were also comparable. The anterior lamellae stayed attached in either the ASM or CJ. vECD was significantly higher in ASM than in CJ with respectively 2062±695 cells/mm2 versus 1632±633 cells/mm2 after 3 days either a cell loss of 20.5% and 38.5% respectively (p=0.0062) and 1082±649 versus 935±691 cells/mm2 for the 10-day period either a cell loss of 132% and 164% respectively (p=0.005). Grafts thickness did not differ after 3 days 219±25 µm in ASM versus 182±39 µm (p=0.063) or 10 days respectively 221±58 µm versus 189±48 µm (p=0.06). CONCLUSION: The storage of precut DSAEKs into the ASM allows a better preservation of grafts without use on deswelling storage medium. Nevertheless, the cell loss remains high after 10 days, suggesting a significant cell stress.

PURPOSE: The number of endothelial grafts precut by eye banks increases. Their shelf life is limited to a few days. We previously demonstrated the superiority of an active storage machine (ASM) over organ culture (passive) for whole corneas. AIMS: To measure the endothelial viability of pre-dissected DMEK after 3 and 10 days of storage in our ASM in a preclinical study. METHODS: Pairs of human corneas were included. The endothelial cell density (ECD in cells/mm2), thickness and transparency of corneas were measured before graft preparation. Descemet's membrane (DM) was peeled using the no-touch technique leaving the graft attached to the center of the cornea (on approx. 1mm2). After randomization, one cornea was kept in organ culture (OC) and the other in the ASM (21 mmHg, 2.6 µL/min) in the same medium (CorneaMax, Eurobio). The final viable ECD was determined using the triple staining with Hoechst-Ethidium-Calcein-AM. In addition, the expression of CD166 and NCAM (lateral membranes), ZO-1 (apical junctions), Na+/K+ ATPase (endothelial pump function) and COX-IV (mitochondrial content) was studied by immunostaining to characterize endothelial cells after the storage. RESULTS: Initial ECDs were comparable: 2185±232 cells/mm2 in the ASM versus 2276±328 in OC for the 3-day period and 2680±416 cells/mm2 in the ASM versus 2644±420 in OC for the 10-day period. The DMs did not fold back in either BR or OC. The viable ECD did not differ significantly between the ASM and OC for either storage period: 2378±501 (ASM) versus 2342±503 (OC) for the 3-day period (n=8 pairs and p=0.624) and 2482±288 (ASM) versus 2579±315 (OC) for the 10-day period (n=5 pairs and p=0.176). Corneas were more transparent and thinner in the ASM than in OC after 3 days (916±86 versus 1193±136µm, p=0.0001) and 10 days (957±128 versus 1220±105µm, p=0.0625). The functional and structural markers studied were expressed in both groups after 3 and 10 days, some better preserved in the ASM. CONCLUSION: The storage of precut DMEKs is possible in ASM and OC for at least 10 days. Interestingly, a pre-dissected endothelium continues to partially exert its pump function into the ASM. In practice, this could allow the stroma to be used for DALK without further deswelling. In addition to improving the storage of whole grafts, the ASM allows the storage of precut DMEKs for up to 10 days with excellent endothelial survival.

INTRODUCTION: The quality of the endothelial graft is critical to the success of DMEK and to the survival time of the graft. The peeling technique, preservation method, and skill level of graft preparers need to be evaluated and validated. The most reliable method of evaluation is the viability test based on a triple staining of Hoechst- Ethidium-Calcein AM (H-E-C) which allows the determination of the total number of viable cells on the graft. However, this test has some shortcomings for DMEK grafts: 1) The undesirable fluorescence of the Calcein AM stain prevents accurate viability analysis, especially in cases where the graft is attached to the cornea for preservation; 2) Incompatibility with immunofluorescence (IF) that could provide additional information. The objective of this study is to develop technical tricks to overcome these drawbacks. METHODS: Two strategies were employed to improve Calcein AM staining: 1. Increase the specific fluorescence intensity by changing the diluent and the concentration of Calcein AM; 2. Decrease undesired fluorescence from keratocytes by adding Trypan Blue (BT). In order to combine the IF after the HEC test, an extension wash in PBS was performed. RESULTS: Calcein AM at 4µM diluted in OptiMEM increased fluorescence intensity 3-fold (p=0.0017, n=5) compared with conventional staining at 2µM in PBS. BT decreased the undesired fluorescence of Calcein and thus optimized count variability between different operators by 42% (p=0.0027, n=10) and saved 40% (p=0.0002, n=10) of count time. To perform IF after HEC, prolonged washing in PBS is an effective method to remove residual Calcein fluorescence and allows release of the FITC/Alexa 488 filter. CONCLUSION: This study provides effective technical tips for optimizing the endothelial viability assay using Calcein AM and for performing IF after the viability assay.

The use of ultrafast laser pulses for eye anterior segment surgery has seen a tremendous growth of interest as the technique has revolutionized the field, from the treatment of myopia, hyperopia, and presbyopia in the cornea to laser-assisted cataract surgery of the crystalline lens. For the latter, a comprehensive understanding of the laser-tissue interaction has yet to be achieved, mainly because of the challenge of observing the interaction zone in situ with sufficient spatial and temporal resolution in the complex and multi-layered tissue of the crystalline lens. We report here on the dedicated characterization results of the laser-tissue interaction zone in the ex vivo porcine lens using three different methods: in situ and real-time microscopy, wide-field optical imaging, and phase-contrast microscopy of the histological cross sections. These complementary approaches together revealed new physical and biological consequences of laser irradiation: a low-energy interaction regime (pulse energy below ~1 µJ) with very limited cavitation effects and a stronger photo-disruption regime (pulse energy above 1 µJ) with a long cavitation duration from seconds to minutes, resulting in elongated spots. These advances in the understanding of the ultrafast laser's interactions with the lens are of the utmost importance for the preparation of the next-generation treatments that will be applied to the lens.
RESUMO
Objectives: Corneal transplantation is the most common transplant worldwide and its success critically depends on the management of corneal graft rejection through topical steroid therapy during the first 12 months after surgery. There is currently no published data on adherence after keratoplasty. This pilot study aims to explore the adherence to topical steroid after penetrating keratoplasty using a smart electronic device. Methods: Thirty patients undergoing penetrating keratoplasty were included to evaluate the adherence to topical dexamethasone medication for 12 months after surgery. Patients received the usual post-transplantation treatment (topical dexamethasone) and follow-up after surgery (day 15, months 1, 2, 3, 4, 5, 6, 9, and 12). Adherence to treatment was monitored using the KaliJAR device (Kali Care, Santa Clara, CA, USA), which recorded the number of single-dose units (SDU) discarded. At control visits, data recorded by the device were compared to the manually count of SDU. Adherence ratio and individual adherence curve were explored for all patients. Results: Data from 27 patients showed a high agreement between adherence ratio calculated based on the device data and obtained from manual counting of the discarded SDU (intraclass coefficient correlation of 0.87 [95% CI: 0.738-0.938]). Mean adherence to the treatment over the 12-month study period was 95.2 ± 4%. Conclusions: Adherence to topical dexamethasone for 12 months after corneal transplantation was high. The connected device was able to record accurately the discarded SDU. This approach would be a particular interest in the early identification and personalized follow-up of poorly adherent patients.
RESUMO
STUDY OBJECTIVE: To develop a nomogram for predicting the type of ureteral procedure in pelvic deep endometriosis (DE) surgery (1) and to describe the factors and complications associated with the ureteral procedure (2). DESIGN: Retrospective monocentric study of 920 patients who underwent surgery for pelvic DE between June 2009 and March 2020 in the gynecologic surgery department of the Versailles Hospital Center. The main criterion was evaluation of the ureteral procedure, classified as simple (isolation of the ureter) or complex (dissection of the ureter, segmental ureteral resection, or nephroureterectomy). Postoperative complications, including ureteral stenosis and fistula formation, were tabulated. SETTING: Tertiary referral hospital and expert center in endometriosis. PATIENTS: A total of 920 patients with DE. INTERVENTIONS: Ureteral procedure during surgery for DE. MEASUREMENTS AND MAIN RESULTS: In total, 724 patients (79%) underwent a ureteral procedure, of which 307 (33%) were complex, including 17 (1.8%) segmental ureteral resections. In multivariate analysis, the predictive variables for a complex ureteral procedure were age (p = .036), a previous surgery for endometriosis (p <.01), and ureteral dilatation on magnetic resonance imaging (p <.001). The area under the curve for the model predicting a complex ureteral procedure was 0.68 (95% confidence interval, 0.60-0.71). A complex ureteral procedure was associated with a 3.5% rate of ureteral fistula (n = 15). CONCLUSION: Age, a previous surgery for endometriosis, a rectovaginal nodule size ≥30 mm, endometriotic involvement of the rectum or sigmoid, and ureteral dilatation are significantly associated with a complex ureteral procedure. Our results allowed us to build a nomogram that can be used to better inform patients, anticipate the therapeutic strategy, and optimize the modalities of postoperative surveillance.

PURPOSE: The purpose of this study is to report the 24-month outcomes of a pro re nata (PRN) compared with a treat and extend (T&E) regimen in patients previously treated for neovascular age-related macular degeneration (nAMD). METHODS: This was a 2-year prospective, single-center study. Previously treated patients for nAMD were randomized into two regimen groups: T&E and PRN groups. Main outcome measured was change in best corrected visual acuity (BCVA) from baseline to month 24. Secondary outcomes encompassed anatomical features such as central retinal thickness (CRT), number of intravitreal injections (IVI), and visits required. RESULTS: A total of 124 eyes received the T&E (n = 61) or PRN (n = 63) regimen. At month 24, the mean BCVA change was -4.4 early treatment diabetic retinopathy study (ETDRS) letters (T&E) and -3.4 ETDRS letters (PRN), with a difference of +1.1 ETDRS letters (95% CI [-2.25]; p = 0.006). The mean change in CRT was -10.6 µm (T&E) and -7.9 µm (PRN), with a difference of +2.6 µm (95% CI [+19.2]; p = 0.004). The T&E group had received a mean of +4.6 more injections (95% CI [-7.06; -2.12]; p < 0.001) at month 24. CONCLUSION: There was statistically proven non-inferiority between the PRN and T&E regimens in terms of visual and anatomical outcomes at 24 months, with significantly more IVI administered in the T&E regimen.

PURPOSE: To investigate the repeat corneal transplantation trend in France from 2004 to 2019. METHODS: Review of the prospectively compiled French Biomedicine Agency electronic database containing all corneal transplantation records from 2004 to 2019. The surgical technique, demographic characteristics, diagnosis, and previous graft data were retrieved and analyzed using the Cochran-Armitage trend test. RESULTS: A total of 66,584 corneal transplantations were performed, 51,260 of which were first grafts and 15,324 (23%) were regrafts. For regrafts, 77% were penetrating keratoplasties (PK) and 19.6% were lamellar keratoplasties (LK). Age, hypertonia, glaucoma, trauma, lens surgery, immune disorders, diameter > 8.5 mm, and neovessels in > 2 quadrants were associated with a higher rate of repeat keratoplasty. Keratoconus, secondary endothelial dystrophy, and Fuchs' dystrophy were the principal indications for regrafting. When a previous graft failed, it occurred earlier for patients with LK (4.6 years, median = 2, SD = 7.54) than PK (8.48 years, median = 5, SD = 9.51). Failure within a year was the reason why 28.3% of the LK regrafts and 12.5% of PK regrafts were performed, while for failure within two years these values were 49.9% and 27.8%, respectively. Graft survival decreased with the number of repeat keratoplasty, being more pronounced after a second LK regraft and after a first PK regraft. CONCLUSION: The number of LK regrafts increased continuously, and 1/3 were performed for failure within the year. This rate increased until 2015, after which it stabilized until 2019, probably due to the better mastery of the technique.

Combining work and family roles can have beneficial consequences on health but could also result in chronic stress and adverse health outcomes at older ages. This study aimed to examine combined employment, parenthood, and partnership histories of men and women during the childbearing period (ages 15-49), and to investigate the links of these work and family roles with physical functioning later in life. We used data from the Survey of Health, Ageing and Retirement in Europe (SHARE) with retrospective information on employment, parenthood, and partnership histories for 18,057 men and 20,072 women (n = 38,129) living in 28 different countries belonging to six European welfare clusters. We applied multichannel sequence analysis (MCSQA) and hierarchical clustering to group work-family trajectories into 12 clusters for men and 15 clusters for women. We assessed the association between work-family life courses and grip strength by estimating multivariable linear regression models. Delayed work and family transitions, unstable employment, and the absence of combinations of work and family roles between age 15 and 49 were associated with weaker grip strength in later life for both men and women. Results differed by gender and were framed by the welfare context in which gendered work and family responsibilities unfold across individual life courses. The findings make an important contribution to the domain of gender and health in later life and stress the need to engage more with issues related to the mechanisms linking work and family trajectories to poor health in later life.

The study focuses on understanding the association between parental socio-economic status (SES) and the likelihood of women experiencing a first birth while single, and identifying societal factors that influence this association in 18 North American and European societies. Previous research has shown that single motherhood occurs disproportionately among those from with lower a lower parental SES. The study assesses whether this is caused by parental SES differences in the risk of single women experiencing a first conception leading to a live birth or by parental SES differences in how likely women are to enter a union during pregnancy. Additionally, an assessment is made of whether cross-national differences in these associations can be explained by a country's access to family planning, norms regarding family formation, and economic inequality. Across countries, a negative gradient of parental SES was found on the likelihood of single women to experience a first pregnancy. The negative gradient was stronger in countries with better access to family planning. In some countries, the negative gradient of parental SES was aggravated during pregnancy because women from lower parental SES were less likely to enter a union. This was mostly found in societies with less conservative norms regarding marriage. The results suggest that certain developments in Western societies may increase socio-economic differentials in family demography. SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1007/s10680-021-09591-3.
RESUMO
The link between parental socio-economic status (SES) and the likelihood of having a birth in cohabitation or in marriage varies considerably across countries. Previous studies have referred to the pattern of disadvantage perspective and the second demographic transition theory to explain this cross-national variation. Yet no study has directly tested the explanatory power of both theories in this context. In the current study, hypotheses are formulated about the influence of economic inequality and norms regarding family formation on this relationship. The hypotheses are tested in 19 European and North American countries, using data of the Generations and Gender Survey and four other datasets. The analyses show that in societies that have more traditional family formation norms, women with lower parental SES are more likely to have a birth in cohabitation whereas such differences are not found in less traditional societies. The influence of economic inequality is less clear-cut.
RESUMO
Due to its intrinsic properties, there has been growing interest in human amniotic membrane (hAM) in recent years particularly for the treatment of ocular surface disorders and for wound healing. Herein, we investigate the potential use of hAM and amnion-chorion membrane (ACM) in oral surgery. Based on our analysis of the literature, it appears that their applications are very poorly defined. There are two options: implantation or use as a cover material graft. The oral cavity is submitted to various mechanical and biological stimulations that impair membrane stability and maintenance. Thus, some devices have been combined with the graft to secure its positioning and protect it in this location. This current opinion paper addresses in detail suitable procedures for hAM and ACM utilization in soft and hard tissue reconstruction in the oral cavity. We address their implantation and/or use as a covering, storage format, application side, size and number, multilayer use or folding, suture or use of additional protective covers, re-application and resorption/fate. We gathered evidence on pre- and post-surgical care and evaluation tools. Finally, we integrated ophthalmological and wound healing practices into the collected information. This review aims to help practitioners and researchers better understand the application of hAM and ACM in the oral cavity, a place less easily accessible than ocular or cutaneous surfaces. Additionally, it could be a useful reference in the generation of new ideas for the development of innovative protective covering, suturing or handling devices in this specific indication. Finally, this overview could be considered as a position paper to guide investigators to fulfill all the identified criteria in the future.
RESUMO
Purpose: To characterize the corneal epithelium (CE) and limbal epithelium (LE) of human corneas stored in an innovative active storage machine (ASM) after a period of organ culture (OC). Methods: Corneas unsuitable for graft and stored in a standard commercial OC medium for 2 to 5 weeks were transferred into our ASM for 14 days. The ASM actively maintained an overpressure on the endothelial side (20 mm Hg) while ensuring medium renewal. We compared three modalities of storage in the ASM's epithelial chamber: (1) alternating exposure to a supplemental hormonal epithelial medium (SHEM) and air (air-lifting), (2) continuous immersion in SHEM, and (3) continuous immersion in OC medium. Passive immersion of the whole cornea in OC medium or of the CE in SHEM with or without airlifting served as controls. Paired corneas were used for better comparability. Histology, differentiation (by immunolabeling), and ultrastructure were analyzed at the end. Results: The ASM with air-lifting was most effective in regenerating a pluristratified and differentiated CE (apical ZO-1 and MUC16 staining and regeneration of the glycocalyx). In addition, the LE was stratified with preserved expression of ABCB5. The ASM with immersion in SHEM or OC medium gave a less stratified and differentiated CE. In the three control groups, the epithelia, when present, were paucistratified and less differentiated. Conclusions: In human corneas previously stored in OC, the ASM regenerates a CE with differentiation characteristics close to normal. Translational Relevance: Regeneration of the epithelium of human corneas discarded by eye banks will increase tissue availability for research.

Research on the relationship between religiosity and fertility intentions revealed substantial cross-national differences. In some countries, a strong and positive effect of religiosity on fertility intentions was found, while in others, the effect was weaker or not significant, and the reasons underlying these cross-national differences are still unclear. The aim of this article is to explain these macro-level differences from the perspective of the prevailing gender regime. We argue that in countries with more traditional regimes, a stronger effect of religiosity on fertility intentions could be expected than in countries with a more egalitarian view. We make use of the first wave of the Generations and Gender Survey and incorporate data from a total of 12 European countries in our analysis. We examine the influence of gender regime according to various macro-level indicators on gender attitudes and gender equality using meta-regression analyses. We also conduct robustness checks using other indicators such as the Gender Development Index. Our results reveal that the gender regime is only able to explain these differences in certain situations, specifically those relating to the long-term fertility intentions of men.
RESUMO
While the literature has documented a general increase in parental investment in children, both in terms of financial and time investment, the motives for this increase remain unclear. This paper aims at shedding light on these motives by examining parents' own narratives of their parenting experiences from the vantage point of three theoretical perspectives. In doing so, the paper brings side-by-side the goal of providing children with human and social capital to improve their future labour market prospects, the pressures on parents to conform to new societal standards of good and intensive parenting, and the experience of parenting as part of self-development. The data come from a qualitative study of middle-income parents in Canada and the USA. The results provide some support for each of these perspectives, while also revealing how they jointly help explain parents' large investment in their children as well as the tensions and contradictions that come with it.
RESUMO
The aim of this study was to examine the positive relationship between religiosity and fertility from the perspective of perceived consequences of parenthood. Previous studies in Germany have found that highly religious people ascribe higher benefits and lower costs to having children. Furthermore, the impact of costs and benefits on fertility is less pronounced among the highly religious. This study tested these mechanisms for fertility intentions and in the context of Poland - a country with a low fertility rate and high religiosity in comparison to other European countries. A sample of 4892 men and women of childbearing age from the second wave of the Polish version of the Generations and Gender Survey conducted in 2014/2015 was used. First, the extent to which perceived costs and benefits mediate the impact of religiosity on fertility intentions was analysed. Second, whether religiosity moderates the impact of perceived costs and benefits on fertility intentions was investigated. The results show that part of the positive effect of religiosity on fertility intentions can be explained by more-religious people seeing higher benefits of having children. Furthermore, but only in the case of women, religiosity moderates the impact of perceived costs on fertility intentions, suggesting that the effect of perceived costs decreases with increasing religiosity.

BACKGROUND: To identify predictive factors for exudation for quiescent choroidal neovessels (qCNV) in the fellow eyes of eyes treated for a neovascular age-related macular degeneration (AMD). METHODS: Prospective observational study. One hundred and forty-four contralateral eyes of 144 patients treated for wet AMD were analysed. At a baseline visit, multimodal imaging including dye angiographies and optical coherence tomography angiography (OCT-A) was performed in order to detect qCNV. Patients were followed up for 12 months with a monthly assessment. The manifestation of any type of exudation (either intra- or subretinal fluid or hyperreflective subretinal material) was monitored. RESULTS: The prevalence of qCNV in the treatment-naive eyes was 15.9% with an incidence over a 12-month period of 2.8%. In total, 40.7% of the overall neovessels remained stable with no sign of exudation, while 59.3% presented some fluid during the follow-up. A statistically significant relationship was established for the following variables preceding the exudation: increase in central macular thickness (OR = 116; 95% CI [4.74; 50530] p = 0.038), increase in pigment epithelial detachment height (OR = 1.76; 95% CI [1.17; 3.18] p = 0.021) and width (OR = 1.53; 95% CI [1.12; 2.62] p = 0.042), increase in neovessels' surface on OCT-A (OR = 6.32; 95% CI [1.62; 51.0] p = 0.033), emergence of a branching pattern (OR = 7.50; 95% CI[1.37; 61.5] p = 0.032) and appearance of a hypointense halo surrounding the lesion (OR = 10.00; 95% CI [1.41; 206] p = 0.048). CONCLUSIONS: The risk of exudation in the treatment-naive fellow eyes of eyes treated for neovascular AMD was notably increased in the presence of qCNV. The biomarkers identified will help to detect their activation in order to ensure prompt antiangiogenic therapy.
