Assisted reproductive technologies (ART) represent commonly utilized management strategies for infertility with multifactorial causes (including genetically predisposed diseases). Amongst ART, in vitro fertilization (IVF) is the most popular. IVF treatment may predispose the mother to increased risks and complications during pregnancy, and there may be adverse fetal outcomes. Hormonal therapies, including oral contraceptives, may impair glucose and lipid metabolism, and promote insulin resistance and inflammation. IVF treatment involves administration of reproductive hormones, similar in composition but in much higher doses than those used for oral contraception. The provision of IVF reproductive hormones to mice associates with glucose intolerance. In addition, the physiological and hormonal changes of pregnancy can trigger an inflammatory response, and metabolic and endocrine changes. There is controversy regarding the potential effects of IVF hormonal therapies in the promotion of diabetogenic and inflammatory states, additional to those that occur during pregnancy, and which may therefore predispose women with IVF-conceived pregnancies to adverse obstetric outcomes compared with women with spontaneously conceived pregnancies. This review summarizes the limited published evidence regarding the effect of IVF-based fertility therapies on glucose homeostasis, insulin resistance, cardio-metabolic profile, and markers of inflammation.PURPOSE To determine if pre-implantation genetic testing (PGT) shifts the sex ratio (SER), the ratio of male to female births in a population normalized to 100 and typically stable at 105, following in vitro fertilization (IVF). METHODS Data from 2014 to 2016 was requested from the Society for Assisted Reproductive Technologies (SART) database including fresh and frozen transfer cycles. Women with a singleton live birth following a fresh or frozen autologous embryo transfer of a PGT blastocyst, non-PGT blastocyst, or non-PGT cleavage stage embryo were included. The SER between groups was compared using chi-square tests. SB239063 research buy Modified Poisson regression modeled the relative risk (RR) of having a male compared to a female among PGT blastocyst transfers versus non-PGT cleavage and blastocyst transfers adjusting for age, BMI, smoking status, race, parity, number of oocytes retrieved, and clinic region. RESULTS The SER was 110 among PGT blastocyst offspring, 107 among non-PGT blastocyst offspring (p = 0.005), and 99 among non-PGT cleavage offspring (p  less then  0.001). The risk of having a male infant was 2% higher among PGT blastocyst transfers compared to non-PGT blastocyst transfers (RR 1.02; 95% CI 1.01, 1.04). The risk was 5% higher among PGT blastocyst transfers compared to non-PGT cleavage transfers (RR 1.05; 95% CI 1.02, 1.07). The association between PGT and infant gender did not significantly differ by region (p = 0.57) or parity (p = 0.59). CONCLUSION Utilizing PGT shifts the SER in the IVF population from the standard of 105 to 110, increasing the probability of a male offspring.Treatment outcomes in pediatric lymphoma have improved substantially over the past 2 decades; however, the prognosis for patients with high risk or relapsed disease remains poor. We evaluated outcomes of high-dose chemotherapy (HDC) and autologous stem cell transplantation (auto-SCT) in 56 pediatric lymphoma patients. Patients received nitrosourea (51 BCNU; 5 ACNU), etoposide, and cyclophosphamide (BEC; AEC). Median age at HDC/auto-SCT was 12 years (range 2-17 years). Forty-four patients underwent HDC/auto-SCT because they did not achieve complete remission after induction chemotherapy. Eight patients showed relapse and four NK/T-cell lymphoma patients also underwent HDC/auto-SCT. BCNU pneumonitis was diagnosed in nine (16.0%) patients. Eight (14.3%) relapsed after HDC/auto-SCT. Treatment-related mortality occurred in three cases. Five-year event-free survival and overall survival rates were 74.8% [72.7% non-Hodgkin's lymphoma (NHL); 83.3% Hodgkin's disease (HD); 72.7%] and 83.6% (81.6% NHL; 91.7% HD), respectively. HDC/auto-SCT with BEC or AEC regimen for pediatric high-risk lymphoma patients showed feasible outcomes. However, treatment modifications are warranted to reduce relapse and toxicity.The language and social skill deficits associated with autism spectrum disorder (ASD) warrant further study. Existing research has focused on the contributions of pragmatic language to social skills, with little attention to other aspects of language. We examined the associations across three language domains (semantics, syntax, and pragmatics) and their relations to parent- and teacher-rated social skills among children with ASD. When parent-reported language skills were considered simultaneously, only semantics significantly predicted children's social skills. For teacher-reported language skills, all three language domains predicted children's social skills, but none made unique contributions above and beyond one another. Further research should consider the impact of social context on language expectations and interventions targeting semantic language on children's development of social skills.The aim of this meta-analysis was to investigate factors associated with resilience in familial caregivers of children with developmental disabilities. The protocol was registered in the PROSPERO database, with the registration number CRD42018105180. Several electronic databases were searched for studies. A random-effects meta-analysis was performed on 26 selected studies that associated resilience to an array of other variables (i.e., psychological distress, social support, coping, perceived health, life satisfaction). Overall, the significant pooled effect sizes were small to medium, ranging from r = 0.291 for coping to r = 0.442 for social support. Although the literature on the topic has improved, there is a lot of study heterogeneity and the need for focusing on male caregivers becomes evident.Extracellular magnesium ion ([Mg2+]) is a well-known voltage-dependent blocker of NMDA receptors, which plays a critical role in the regulation of neuronal plasticity, learning, and memory. It is generally believed that NMDA receptor activation involves in Mg2+ being removed into extracellular compartment from the channel pore. On the other hand, Mg2+ is one of the most abundant intracellular cations, and involved in numerous cellular functions. However, we do not know if extracellular magnesium ions can influx into neurons to affect intracellular signaling pathways. In our current study, we found that extracellular [Mg2+] elevation enhanced CREB activation by NMDA receptor signaling in both mixed sex rat cultured neurons and brain slices. Moreover, we found that extracellular [Mg2+] led to CREB activation by NMDA application, albeit in a delayed manner, even in the absence of extracellular calcium, suggesting a potential independent role of magnesium in CREB activation. Consistent with this, we found that NMDA application leads to an NMDAR-dependent increase in intracellular-free [Mg2+] in cultured neurons in the absence of extracellular calcium.
