A systematic review on the impact of nutrition and possible supplementation on the deficiency of vitamin complexes, iron, omega-3-fatty acids, and lycopene in relation to increased morbidity in women after menopause.

A balanced and healthy diet during the menopausal transition and after menopause is crucial for women to reduce the risk for morbidities and chronic diseases due to deficiency of essential nutrients. PURPOSE: The objective of this study was to conduct a systematic review of studies that analyzed the impact of vitamin and nutrient deficiencies in postmenopausal women in relation to increased morbidities and chronic conditions. METHODS: Observational studies were searched in the databases PubMed, UpToDate, and Google Scholar. RESULTS: We searched 122 studies, of which 90 were included in our analysis. The meta-analysis of the data could not be performed because of the heterogeneity of the statistical methods in the included studies. In our study, we focused on the aspects of vitamin B6, vitamin B12, vitamin D, iron, omega-3-fatty acids, and lycopene, belonging to the family of carotenoids. Postmenopausal women with deficiencies of these nutrients are more vulnerable to comorbidities such as cardiovascular and cerebrovascular events, metabolic diseases, osteoporosis, obesity, cancer and neurodegenerative diseases such as Parkinson's disease, Alzheimer's disease, depression, cognitive decline, dementia, and stroke. We concluded that women after menopause tend to have a greater probability of suffering from deficiencies in various vitamins and nutrients, and consequently have an increased risk of developing morbidities and chronic diseases. CONCLUSION: In conclusion, maintaining optimum serum levels of nutrients and vitamins, either through a balanced and healthy diet consuming fresh fruits, vegetables, and fats or by taking appropriate supplementation, is essential in maintaining optimal health-related quality of life and reducing the risk for women during the menopausal transition and after menopause. Nevertheless, more recent studies need to be assessed to formulate adequate recommendations to achieve positive clinical outcomes.

Perimenopause and Postmenopause - Diagnosis and Interventions. Guideline of the DGGG and OEGGG (S3-Level, AWMF Registry Number 015-062, September 2020).

Aim The aim of the interdisciplinary S3-guideline Perimenopause and Postmenopause - Diagnosis and Interventions is to provide help to physicians as they inform women about the physiological changes which occur at this stage of life and the treatment options. The guideline should serve as a basis for decisions taken during routine medical care. This short version lists the statements and recommendations given in the long version of the guideline together with the evidence levels, the level of recommendation, and the strength of consensus. Methods The statements and recommendations are largely based on methodologically high-quality publications. The literature was evaluated by experts and mandate holders using evidence-based medicine (EbM) criteria. The search for evidence was carried out by the Essen Research Institute for Medical Management (EsFoMed). To some extent, this guideline also draws on an evaluation of the evidence used in the NICE guideline on Menopause and the S3-guidelines of the AWMF and has adapted parts of these guidelines. Recommendations Recommendations are given for the following subjects: diagnosis and therapeutic interventions for perimenopausal and postmenopausal women, urogynecology, cardiovascular disease, osteoporosis, dementia, depression, mood swings, hormone therapy and cancer risk, as well as primary ovarian insufficiency.

Diagnosis and Therapy Before Assisted Reproductive Treatments. Guideline of the DGGG, OEGGG and SGGG (S2k Level, AWMF Register Number 015-085, February 2019) - Part 1, Basic Assessment of the Woman.

Introduction Supporting and counselling couples with fertility issues prior to starting ART is a multidisciplinary diagnostic and therapeutic challenge. The first German/Austrian/Swiss interdisciplinary S2k guideline on "Diagnosis and Therapy Before Assisted Reproductive Treatments (ART)" was published in February 2019. This guideline was developed in the context of the guidelines program of the German Society of Gynecology and Obstetrics (DGGG) in cooperation with the Swiss Society of Gynecology and Obstetrics (SGGG) and the Austrian Society of Gynecology and Obstetrics (OEGGG). Aims One third of the causes of involuntary childlessness are still unclear, even if the woman or man have numerous possible risk factors. Because the topic is still very much taboo, couples may be socially isolated and often only present quite late to a fertility center. At present, there is no standard treatment concept, as currently no standard multidisciplinary procedures exist for the diagnostic workup and treatment of infertility. The aim of this guideline is to provide physicians with evidence-based recommendations for counselling, diagnostic workup and treatment. Methods This S2k guideline was developed on behalf of the Guidelines Commission of the DGGG by representative members from different professional medical organizations and societies using a structured consensus process. Recommendations The first part of this guideline focuses on the basic assessment of affected women, including standard anatomical and endocrinological diagnostic procedures and examinations into any potential infections. Other areas addressed in this guideline are the immunological workup with an evaluation of the patient's vaccination status, an evaluation of psychological factors, and the collection of data relating to other relevant factors affecting infertility. The second part will focus on explanations of diagnostic procedures compiled in collaboration with specialists from other medical specialties such as andrologists, human geneticists and oncologists.

Diagnosis and Treatment Before Assisted Reproductive Treatments. Guideline of the DGGG, OEGGG and SGGG (S2k Level, AWMF Register Number 015-085, February 2019) - Part 2, Hemostaseology, Andrology, Genetics and History of Malignant Disease.

Introduction Supporting and counselling couples with fertility issues prior to starting ART is a multidisciplinary diagnostic and therapeutic challenge. The first German-language interdisciplinary S2k guideline on "Diagnosis and Therapy Before Assisted Reproductive Treatments (ART)" was published in February 2019. The guideline was developed in the context of the guidelines program of the German Society of Gynecology and Obstetrics (DGGG) in cooperation with the Swiss Society of Gynecology and Obstetrics (SGGG) and the Austrian Society of Gynecology and Obstetrics (OEGGG). Aim In one third of cases, the cause of involuntary childlessness remains unclear, even if the woman or man have numerous possible risk factors. Because the topic is still very much taboo, couples may be socially isolated and often only present quite late to a fertility center. There is no standard treatment concept for these patients at present, as there are currently no standard multidisciplinary procedures for the diagnostic workup and treatment of infertility. The aim of this guideline is to provide physicians with evidence-based recommendations for counselling, diagnosis and treatment. Methods This S2k guideline was developed on behalf of the Guidelines Commission of the DGGG by representative members from different professional medical organizations and societies using a structured consensus process. Recommendations This second part of the guideline describes the hematological workup for women as well as additional diagnostic procedures which can be used to investigate couples and which are carried out in cooperation with physicians working in other medical fields such as andrologists, geneticists and oncologists.

Influence of oral vitamin and mineral supplementation on male infertility: a meta-analysis and systematic review.

This meta-analysis and systematic review investigated evidence of the effect of oral micronutrient supplementation on male fertility. Following searches of PubMed, Ovid/Ovid Medline(r) and Embase, 18 randomized, double-blind, placebo-controlled trials were included in the meta-analysis (seven studies) and/or the systematic review (12 studies). The meta-analysis showed significant improvement in semen parameters for selenium (200µg/day and 100µg/day) (standard mean difference [SMD] 0.64 for oligozoospermia, 1.39 for asthenozoospermia), L-carnitine (2 g/day) and acetyl-L-carnitine (LAC; 1 g/day) combined (SMD 0.57 for asthenozoospermia), and co-enzyme Q10 (200 and 300 mg/day) (SMD 0.95 for oligozoospermia, 1.48 for asthenozoospermia, 0.63 for teratozoospermia). The systematic review identified promising data for supplementation with 66 mg/day zinc combined with folic acid (5 mg/day), and the polyunsaturated fatty acids eicosapentaenoic acid (EPA; 1.12 g/day) and docosahexaenoic acid (DHA; 0.72 g/day). Pregnancy rate was evaluated in a limited number of trials (four in the meta-analysis, three in the systematic review). This analysis suggests supplementation with selenium (alone or combined with N-acetylcysteine), co-enzyme Q10 and the combinations L-carnitine + acetyl-L-carnitine, folic acid + zinc and EPA + DHA is beneficial in the treatment of male infertility. Because of the small number of available studies and low number of participants, further well-designed clinical studies are needed to obtain a better overview of efficient methods of treating male infertility.

The role of transvaginal ultrasonography for detecting ovarian cancer in an asymptomatic screening population: a systematic review.

INTRODUCTION: The purpose of this study was to systematically analyze the effect of transvaginal ultrasonography in an asymptomatic female population as an annual screening procedure with regard to mortality data. Studies were evaluated descriptively on their strengths and weaknesses considering the methods and results. METHODS: We evaluated 632 international studies by selecting only randomized controlled trials (RCTs). Three RCTs concerning transvaginal ultrasonography were found, performed in Japan, the USA, and Great Britain. DISCUSSION: Currently, no clear recommendation for the screening for ovarian cancer in an asymptomatic population can be given based on these three studies. The authors could not show a change in mortality using transvaginal ultrasonography for annual screening. CONCLUSION: An annual palpation does not offer a beneficial effect. The development of new ultrasound machines with higher image resolution in combination with a well-standardized algorithm for ovarian cancer in upcoming years might provide an improvement regarding mortality. The current studies do not show a benefit in screening an asymptomatic population annually with transvaginal ultrasonography, but the most recent publication showed a trend toward lower mortality in patients who underwent screening after 7-14 years of follow-up. Nevertheless, all three heterogeneous RCTs had weaknesses in their methods and therefore they neither contradict the general recommendation for screening in an asymptomatic population nor do they support it.

The effect of micronutrient supplements on male fertility.

PURPOSE OF REVIEW: To describe the beneficial effects of micronutrient supplementation on male fertility. RECENT FINDINGS: Several micronutrients have beneficial effects on sperm quality, as well on male fertility (e.g. pregnancy rate). A deliberate use of micronutrients might be helpful for infertile patients. Healthcare providers should be aware that supplements contain the studied dose. SUMMARY: Male sterility is becoming increasingly important because of various factors. In addition to the avoidable risk factors (alcohol and smoking), unchangeable factors are also likely involved in the genesis. Modern reproductive medicine methods help resulting in decent pregnancy rates in subfertile men. However, in addition to reproductive medicine methods, factors other than cessation of smoking and alcohol consumption can influence the fertility of men. Several studies have reported a significant increase in sperm quality and pregnancy rates when the men were supplemented by specific vitamins and micronutrients.The present review gives an overview of the study results and discusses specific legal requirements (e.g. 'upper limits').

The effect of micronutrient supplements on female fertility.

PURPOSE OF REVIEW: Benefit of micronutrient supplementation on female fertility. RECENT FINDINGS: Reports of randomized trials are rare. Most studies are focused on multivitamin supplementations. For some micronutrients, a positive impact on fertility could be shown. This article reviews the available clinical studies as well as the pathophysiological background of possible effects and summarizes the potential benefits of selected micronutrients on female fertility. SUMMARY: Apart from lowering the malformation risk by periconceptional supplementation of folic acid, substitution with different micronutrients, particularly folic acid, vitamin B6, vitamin C, vitamin D, vitamin E, iodine, selenium, iron, and DHA might have a positive impact on infertility treatment. The multivitamin formulation should take the pathophysiology, clinical studies, and upper limits into account.

Diagnosis and therapy of polycystic ovarian syndrome: results of a survey among German gynecologists with a review on literature.

OBJECTIVE: Polycystic ovarian syndrome is one of the most frequent endocrine dysfunctions in women in their fertile age. To date, a clear definition of the disease remains controversial among experts, partly because study results concerning diagnostics and therapy are incoherent. In this survey, we intend to give an insight into the diagnostics and treatment regimes of PCOS in Germany and subsequently compare these results to the current recommendations found in international literature. DESIGN: In 2005, 7,000 outpatient gynecologists received a questionnaire with questions on PCOS definition, diagnostics and treatment. RESULTS: The survey shows that it remains difficult for gynecologists to restrict themselves to the few definition criteria defined in the 2003 Rotterdam PCOS Consensus Workshop. Nevertheless, therapy and diagnosis of PCOS show a uniform treatment pattern. The current recommendations found in international literature have been widely implemented into clinical practice. Modern therapeutic approaches such as the use of metformin are increasingly acknowledged. CONCLUSION: Further studies dealing with the diagnosis and therapy of PCOS will be necessary in order to establish guidelines, especially when looking at patients without a desire for reproduction.

Role of secondary cytoreductive surgery in ovarian cancer relapse: who will benefit? A systematic analysis of 240 consecutive patients.

BACKGROUND AND OBJECTIVES: In contrast to primary ovarian cancer, the value of surgery in relapsed-OC (ROC) remains unclear. We evaluated surgical and clinical outcome of secondary cytoreduction in ROC. METHODS: All consecutive ROC patients who underwent secondary tumor-debulking surgery were systematically analyzed as based on a validated intraoperative documentation tool. Tumor dissemination pattern, operative and clinical outcome were evaluated. Cox-regression analysis was performed to identify independent predictors of mortality. RESULTS: Between 09/2000 and 10/2008, 240 operations were evaluated; 184 patients (81.1%) were platinum-sensitive and 43 (20%) platinum-resistant. 47.5% of the patients had ascites, while 85.8% presented a multifocal tumor dissemination pattern. In 53.8% a complete tumor resection was achieved; in another 24.2%, postoperative tumor residuals were < 1 cm. In multivariate analysis, no tumor resection (HR: 7.6; 95% CI: 2.9-19.9), ascites > 500 ml (HR: 6.76; 95% CI: 3.77-12.1), platinum resistance (HR: 3.1; 95% CI: 1.26-7.7), and initial FIGO stage IV (HR: 2.86; 95% CI: 1.16-7) were the most significant risk factors for mortality. Median OS was 42.3 months (95% CI: 24.37-60.2); 17.7 months (95% CI: 12.27-23.13); and 7.7 months (95% CI: 3.1-12.3) for patients with complete tumor resection, tumor residuals ≤ 1 and > 1 cm, respectively (trend P-value < 0.001). CONCLUSIONS: Absence of ascites, platinum-sensitivity, initial FIGO stage < IV, and complete tumor resection correlate with a significantly better long-term prognosis after ROC surgery. However, a significant trend of continuously improving survival associated with increasing tumor reduction rates could be identified even in patients where a complete tumor resection is not achievable.

Advantages and challenges of oestrogen-free hormonal contraception.

BACKGROUND: Not all women tolerate hormonal contraceptives containing oestrogens. METHODS: The authors selected and evaluated relevant publications on the advantages and challenges of oestrogen-containing and oestrogen-free oral contraceptives obtained from the MEDLINE and Google databases from January 2000 to January 2010. In addition, the reference lists from the obtained publications as well as the authors' clinical experience served as additional sources of information. Emphasis was placed on the common adverse effects and risks associated with oestrogen replacement as well as on the noncontraceptive benefits of combined oral contraceptive pills and progestogen-only pills in the management of menstrual cycle-dependent problems. FINDINGS: Progestogen-only pills have the potential to abolish many of the common adverse effects associated with oestrogen plus progestogen oral contraceptives and can be used to treat various menstrual cycle-dependent problems. However, only a limited number of clinical comparative studies are available. Progestogen-only pills are associated with a more irregular bleeding pattern than contraceptive pills containing oestrogens, especially during the first few months of therapy. As this is not permanent, adequate counselling is essential in order to prevent unnecessary discontinuation of treatment. CONCLUSIONS: Progestogen-only pills offer an effective, convenient, and readily reversible method of contraception that is suitable for women with contraindications for oestrogens.

Why use of dienogest for the first contraceptive pill with estradiol?

Dienogest (DNG) has the essential properties of an effective progestogen for use in a new contraceptive pill using estradiol valerate as estrogenic component -- it inhibits ovulation and protects against endometrial proliferation. DNG is a derivative of norethisterone (NET), but has a cyanomethyl- instead of an ethinyl-group in C17 position which may offer a variety of benefits regarding hepatic effects. The similarity to NET is reflected in the high endometriotropy and in similar pharmacokinetics like short plasma half-live and high bioavailability. However, DNG also elicits properties of progesterone derivatives like neutrality in metabolic and cardiovascular system and considerable antiandrogenic activity, the latter increased by lack of binding to SHBG as specific property of DNG. It has no glucocorticoid and antimineralocorticoid activity and has no antiestrogenic activity with the consequence that possible beneficial estradiol effects should not be antagonized. This may be of special importance for the tolerability and safety of the first pill with estradiol valerate instead of ethinylestradiol, although well-designed postmarketing studies are still ongoing to demonstrate what can be expected on the basis of pharmacology.

Use of dydrogesterone in hormone replacement therapy.

According to the Women's Health Initiative (WHI) study, the most important risks during combined hormone replacement therapy (HRT) are breast cancer, stroke and venous thromboembolism. To date, combinations of estradiol with natural progesterone or its retroisomer dydrogesterone are the only combined HRT regimens for which large case-control or cohort studies show no increase in any of these three risks. Moreover, due to the neutral effect of dydrogesterone on the vascular and metabolic systems, the preventive effect of the estradiol component with respect to myocardial infarction and metabolic syndrome can be maintained if HRT is started early after the menopause. Although a study with the same design as the WHI has not been performed, these results appear to be plausible considering the positive experimental evidence, particularly in the context of breast cancer and cardiovascular risks/benefits. Combination with dydrogesterone avoids endometrial hyperproliferation, maintains the beneficial effects of estradiol (i.e. efficacy against climacteric symptoms and prevention of osteoporotic fractures) and minimizes the most important risks known to be associated with the progestogen components of HRT regimens.

Prognostic value of serum and ascites levels of estradiol, FSH, LH and prolactin in ovarian cancer.

UNLABELLED: The aim of this study was to investigate the influence of sex hormone levels on tumor biology and patients' outcome in ovarian cancer. PATIENTS AND METHODS: One hundred and six patients with ovarian cancer were enrolled into this prospective study. Serum and ascites samples were obtained intraoperatively. Concentrations of estradiol, FSH, LH and prolactin were measured and correlated with parameters of tumor biology, such as FIGO stage, tumor spread and postoperative tumor residual mass. Patients with primary ovarian cancer were compared to patients with recurrent disease. Influence factors on progression-free survival and overall survival were analyzed using the Kaplan-Meyer method. RESULTS: Serum FSH concentrations were significantly higher and estradiol concentrations in ascites were significantly lower in patients with recurrent disease. According the multivariate analysis, only FSH level in ascites was seen to be an independent prognostic factor for patients' survival. CONCLUSION: High level of FSH in the ascites provides prognostic information in patients with ovarian cancer and is inversely correlated with patients' survival.
