Women's reflections on timing of motherhood: a meta-synthesis of qualitative evidence.

INTRODUCTION: Fertility declines with increasing age, especially in women. In recent decades women's age at the birth of their first child has risen markedly in many countries, and an increasing number of women do not establish a family until their late-twenties to mid-thirties. Although there can be various reasons that couples experience fertility problems, advanced maternal age is the most frequent cause for difficulties with achieving pregnancy. OBJECTIVE: In this meta-synthesis, we investigated reflections on timing of motherhood in women who have not yet had children. METHODS: A systematic literature search of six electronic databases and manual searches of reference lists identified eight qualitative studies published between 2011 and 2018 that focused on women's reflections on timing of motherhood. The studies were assessed with the Critical Assessment Skills Programme (CASP) quality appraisal tool. The results were synthesized using Noblit and Hare's meta-ethnographic approach as described by Malterud. FINDINGS: An overall theme of 'Timing of motherhood' and four overlapping subthemes were identified: Making a life-changing decision, The right time, Fear of regret, and Plan B. The dilemmas associated with timing of motherhood leave women of reproductive age balancing their priorities and values against a biological deadline for having children naturally or through assisted reproductive technology. CONCLUSIONS: Women of reproductive age are aware that they must make a life-changing decision as to if or when to have children, but they consider having children at 'the right time' to be important. Simultaneously, while some women are reluctant to have children for various reasons, they express fear that waiting too long could result in their regretting not having children later in life. Although women of reproductive age express concern about their ability to achieve pregnancy, they have limited focus on the medical risks associated with postponing motherhood. There is a need to establish preventive health initiatives to support women of reproductive age in their considerations regarding timing of motherhood. TRIAL REGISTRATION NUMBER: PROSPERO: CRD42020175151.

In many countries, women's age at the birth of their first child has risen markedly, and an increasing number of women do not establish a family until their late-twenties to mid-thirties. This causes risk of couples experiencing fertility problems, as fertility declines with increasing age. Although fertility problems can be caused by various reasons, advanced maternal age is the most frequent cause for women having difficulties achieving pregnancy. In this study, we investigated reflections on timing of motherhood in women who have not yet had children. Through a systematic literature search we identified eight qualitative studies published between 2011 and 2018 that focused on women's reflections on timing of motherhood. The included studies were synthesized using a meta-ethnographic approach. We identified an overall theme 'Timing of motherhood' and four overlapping subthemes: Making a life-changing decision, The right time, Fear of regret, and Plan B. The dilemmas associated with timing of motherhood leave women of reproductive age balancing their priorities and values against a biological deadline for having children naturally or through assisted reproductive technology. Women of reproductive age are aware that they must make a life-changing decision as to if or when to have children, but they consider having children at 'the right time' to be important. Simultaneously, while some women are reluctant to have children for various reasons, they express fear that waiting too long could result in their regretting not having children later in life. Although women of reproductive age express concern about their ability to achieve pregnancy, they have limited focus on the medical risks associated with postponing motherhood, which emphasizes the need for establishing preventive health initiatives to support women of reproductive age in their considerations regarding timing of motherhood.

Chronic endometritis - is it time to clarify diagnostic criteria?

Chronic endometritis is a persistent, low-intensity inflammation of endometrial mucosa, characterized by the infiltration of plasma cells into the endometrial stroma This immunological alteration is thought to be a consequence of a bacterial infection. For a long time, chronic endometritis was poorly investigated and rarely considered in clinical practice because it is either asymptomatic or presents with no specific symptoms. Its association with adverse effects on fertility and retrospectively reported effectiveness of antibiotic treatment were the main reasons for a growing interest in this endometrial pathology. Chronic endometritis is now a hot topic in recurrent pregnancy loss and recurrent implantation failure research. Nevertheless, there are still no recommendations to include chronic endometritis investigation in a clinical evaluation of infertile patients. The uncertain role of this condition is an effect of significant differences in study results presented by different research groups. One important reason for these inconsistent findings is a lack of standardised chronic endometritis diagnostic methods. We present a review of the literature, focusing on the currently available chronic endometritis diagnostic techniques. The review is subdivided into three parts concerning the diagnostic accuracy of three main diagnostic modalities. Histopathological examination of endometrial tissue, hysteroscopic evaluation of uterine cavity and identification of the bacterial factor. In conclusion, it is of great importance to establish a consensus on the diagnostic criteria for chronic endometritis. This is the only way to enhance international cooperation and create well-design multicenter studies to evidence the role of this endometrial pathology in infertility.

Assessment of In Vitro and In Silico Protocols for Sequence-Based Characterization of the Human Vaginal Microbiome.

The vaginal microbiome has been connected to a wide range of health outcomes. This has led to a thriving research environment but also to the use of conflicting methodologies to study its microbial composition. Here, we systematically assessed best practices for the sequencing-based characterization of the human vaginal microbiome. As far as 16S rRNA gene sequencing is concerned, the V1-V3 region performed best in silico, but limitations of current sequencing technologies meant that the V3-V4 region performed equally well. Both approaches presented very good agreement with qPCR quantification of key taxa, provided that an appropriate bioinformatic pipeline was used. Shotgun metagenomic sequencing presents an interesting alternative to 16S rRNA gene amplification and sequencing but requires deeper sequencing and more bioinformatic expertise and infrastructure. We assessed different tools for the removal of host reads and the taxonomic annotation of metagenomic reads, including a new, easy-to-build and -use reference database of vaginal taxa. This curated database performed as well as the best-performing previously published strategies. Despite the many advantages of shotgun sequencing, none of the shotgun approaches assessed here agreed with the qPCR data as well as the 16S rRNA gene sequencing.IMPORTANCE The vaginal microbiome has been connected to various aspects of host health, including susceptibility to sexually transmitted infections as well as gynecological cancers and pregnancy outcomes. This has led to a thriving research environment but also to conflicting available methodologies, including many studies that do not report their molecular biological and bioinformatic methods in sufficient detail to be considered reproducible. This can lead to conflicting messages and delay progress from descriptive to intervention studies. By systematically assessing best practices for the characterization of the human vaginal microbiome, this study will enable past studies to be assessed more critically and assist future studies in the selection of appropriate methods for their specific research questions.

Cesarean scar pregnancy: a systematic review of treatment studies.

OBJECTIVE: To study treatment modalities for cesarean scar pregnancies (CSPs), focusing on efficacy and complications in relation to study quality. DESIGN: Systematic review. SETTING: Not applicable. PATIENT(S): A total of 2,037 women with CSP. INTERVENTION(S): Review of MEDLINE, EMBASE, and Cochrane Library to find studies including five or more women. Data were extracted on primary treatment modality/efficacy, complications, and future fertility. The level of evidence was categorized according to Oxford Centre for Evidence-based Medicine guidelines. Quality was assessed using The Cochrane Collaboration's Risk of Bias Tools for Randomized Controlled Trials and the modified Delphi techniques for case series. Meta-analysis was impossible owing to multifarious treatments. MAIN OUTCOME MEASURE(S): Successful first-line treatment. Complications were hysterectomy, laparotomy, bleeding >1,000 mL, or blood transfusion. RESULT(S): Fifty-two studies were included: four randomized, controlled trials and 48 case series. Fifteen of the 52 analyzed studies were scored as high quality. Treatment modalities were condensed to 14 different approaches. Combining study quality, level of evidence, efficacy, and safety, five approaches for treating CSP are recommended, depending on availability, severity of patient symptoms, and surgical skills: [1] resection through a transvaginal approach, [2] laparoscopy, [3] uterine artery embolization in combination with dilatation and curettage and hysteroscopy, [4] uterine artery embolization in combination with dilatation and curettage, and [5] hysteroscopy. CONCLUSION(S): This review recommends treatment options for CSP in clinical practice, based on efficacy and safety. The literature supports an interventional rather than medical approach. Present recommendations are primarily based on case series. Multicenter, well-designed studies are needed to draw definite conclusions on how to treat CSP.
