    Sperm freeze-drying; effects on sperm parameters

    Abstract

    Today, sperm cryopreservation is a routine practice in infertility clinics. One of the alternative methods to preserve sperm is freeze-drying. This process consists of three steps. The first step is sample freezing, during which the solvent is separated from the solvent. Water forms ice crystals and the solute is placed between the ice crystals. Freezing may be done in a separate device or in a freeze dryer. The second step is the primary drying, in which the pressure of the device is reduced and heat is used to begin sublimation of the ice crystals. During the third step, which is the secondary drying, the final absorption of the remaining water is usually done by increasing the temperature of the product and slightly reducing the water va

    Abstract

    Background: Synchronization between the embryonic stage and the uterine endometrial lining is important in the outcomes of the vitrified-warmed embryo transfer (ET) cycles.Objective: The aim was to investigate the effect of the exact synchronization between the cleavage stage of embryos and the duration of progesterone administration on the improvement of clinical outcomes in frozen embryo transfer (FET) cycles.Materials and Methods: 312 FET cycles were categorized into two groups:(A) day-3 ET after three days of progesterone administration (n= 177) and (B) day-2 or-4 ET after three days of progesterone administration (n= 135). Group B was further divided into two subgroups: B1: day-2 ET cycles, that the stage of embryos were less than the

    Abstract

    Objective: The aim of this study was to screen the potential of human embryos to develop into expanding blastocysts following in vitro embryo splitting and then assess the quality of the generated blastocysts based on chromosomal characteristics and using morphokinetics.Materials and Methods: In this experimental study, a total of 82 good quality cleavage-stage donated embryos (8-14 cells) were used (24 embryos were cultured to the blastocyst stage as controls and 58 embryos underwent in vitro splitting). After in vitro splitting, the blastomere donor and blastomere recipient embryos were named twin A and twin B, respectively. Morphokinetics and morphological parameters were evaluated using a time-lapse system in the blastocysts developed f

    Abstract

    To investigate the impact of antioxidants in sperm parameters and reduction in reactive oxygen species production during the freeze‐thaw process. PubMed, Scopus, Web of Science, Embase and Cochrane central library were systematically searched. Of the 1583 articles, 23 studies were selected for data extraction. Our results show that antioxidants improved sperm progressive motility (standardised mean difference (SMD)?=?1; 95% CI: 0.62, 1.38; p?

    Abstract

    Aims: The present study aims to compare the survival rate, reconstitution and dislocation of meiotic spindle of mouse oocyte vitrification between open and close systems.Materials & Methods: 131 matured oocytes (containing meiotic spindle) harvested from 6-8 week-old BALB/C and divided into two groups of open and close systems. After exposure of oocytes in vitrification media, oocytes were loaded on cryotop in open group and on Rapid-i in close group, and then vitrified. After warming, oocytes were incubated for 3 hours and evaluated for survival rate, presence and location of re-polymerized meiotic spindle by PolScope system.Findings: Survival rate was significantly higher in open system compared to close system (91.1% vs 68.6%, respective

    LBD Double Burden of Malnutrition Collaborators.
    Journal PapersNature Medicine , 2020 July 2, {Pages }

    Abstract

    A double burden of malnutrition occurs when individuals, household members or communities experience both undernutrition and overweight. Here, we show geospatial estimates of overweight and wasting prevalence among children under 5 years of age in 105 low-and middle-income countries (LMICs) from 2000 to 2017 and aggregate these to policy-relevant administrative units. Wasting decreased overall across LMICs between 2000 and 2017, from 8.4%(62.3 (55.1–70.8) million) to 6.4%(58.3 (47.6–70.7) million), but is predicted to remain above the World Health Organization’s Global Nutrition Target of< 5% in over half of LMICs by 2025. Prevalence of overweight increased from 5.2%(30 (22.8–38.5) million) in 2000 to 6.0%(55.5 (44.8–67.9) million

    Abstract

    BackgroundRigorous analysis of levels and trends in exposure to leading risk factors and quantification of their effect on human health are important to identify where public health is making progress and in which cases current efforts are inadequate. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 provides a standardised and comprehensive assessment of the magnitude of risk factor exposure, relative risk, and attributable burden of disease.MethodsGBD 2019 estimated attributable mortality, years of life lost (YLLs), years of life lived with disability (YLDs), and disability-adjusted life-years (DALYs) for 87 risk factors and combinations of risk factors, at the global level, regionally, and for 204 countries and t

    Abstract

    BackgroundAccurate and up-to-date assessment of demographic metrics is crucial for understanding a wide range of social, economic, and public health issues that affect populations worldwide.

    Abstract

    The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 provides a rules-based synthesis of the available evidence on levels and trends in health outcomes, a diverse set of risk factors, and health system responses. GBD 2019 covered 204 countries and territories, as well as first administrative level disaggregations for 22 countries, from 1990 to 2019. Because GBD is highly standardised and comprehensive, spanning both fatal and non-fatal outcomes, and uses a mutually exclusive and collectively exhaustive list of hierarchical disease and injury causes, the study provides a powerful basis for detailed and broad insights on global health trends and emerging challenges. GBD 2019 incorporates data from 281 586 sources and p

    Abstract

    Many factors, including postponement of marriage, increased life expectancy, and improved success with assisted reproductive technologies have been contributing to increased paternal age in developed nations. This increased average paternal age has led to concerns about adverse effects of advanced paternal age on sperm quality, assisted reproductive outcomes, and the health of the offspring conceived by older fathers. This review discusses the association between advanced paternal age and sperm parameters, assisted reproduction success rates, and offspring health.
