The ongoing COVID-19 pandemic is raising great concern all over the world. The recent introduction of vaccines has offered reason for optimism, however, new issues have arisen, such as vaccine reluctance. The safety of vaccines for pregnant women is one of the most serious of these concerns. The purpose of this review article is to provide updated international vaccine recommendations, results of ongoing studies and clinical trials, and the role of gynecologists in counseling the women to understand the risks versus benefits as well as form an informed decision towards vaccine acceptance for COVID-19.Although COVID-19 infection increases the risk of severe morbidity and mortality in pregnant women, pregnant women were not included in the initial vaccine trials. As a result, safety information is scarce. Nations have differing recommendations, though many have recently approved the COVID-19 immunization in pregnancy following a risk-benefit analysis. The Joint Committee on Vaccination and Immunization (JCVI) of the United Kingdom recently approved an mRNA vaccination for pregnant women. Vaccination is recommended by the CDC, ACOG, ARFM, and WHO. India recently took a stand, with the ICMR and the Ministry of Health and Family Welfare recommending vaccination during pregnancy and lactation. 相似文献

《内经》中存在着多种学术流派,其学派划分方法目前有两种,即以《内经》中的医家名称为纲和以各专题中的不同学说为纲划分。这两种方法均存在不足之处。以阴阳、五行为纲来探讨《内经》中的医学流派应是今后研究的方向之一。 相似文献

Neuronal types contributing to the inner plexiform layer of the cat retina are described based primarily on light microscopy of Golgi-impregnated retinal whole-mounts. Cells have been characterized on morphological criteria that include dendritic branching patterns, dendritic tree sizes, cell body sizes and stratification of processes in the inner plexiform layer. Nine different types of bipolar cell, 22 different types of amacrine cell and 23 different types of ganglion cell can be distinguished using one or more of these morphological criteria. The significance of the different morphological types of cells is discussed, particularly in relationship to the functional bisublamination of the cat inner plexiform layer. 相似文献

To determine whether hepatic microsomal enzyme induction occurs in rats following administration of phenobarbital at doses similar to those used in humans (0.5 to 7.5 mg/kg), UDP-glucuronyl transferase (UDPGT) and cytochrome P-450 activities were measured in liver homogenate and microsomal preparations from control rats and rats treated for 6 days with phenobarbital at 1 and 3 mg per kg per day. While no significant increases in liver weight and protein content of homogenate and microsomal preparations were observed with either dose of the drug, both UDPGT and P-450 activities were enhanced significantly following administration of phenobarbital at 3 mg per kg per day. The activity of P-450 was increased by approximately 30% and that of UDPGT by 15-24 and 45-66%, respectively, employing bilirubin and p-nitrophenol as the acceptor substrate. The extent of induction of bilirubin or p-nitrophenol UDPGT was similar when measured with "native" enzyme or with enzyme activated by UDP-N-acetyl glucosamine, digitonin or deoxycholate. These data suggest that the discordant effects of phenobarbital on UDPGT and cytochrome P-450 previously reported in humans and rats may not be attributable solely to differences in the drug doses employed. 相似文献

Research evidence on the role of dietary sodium in the etiology and pathogenesis of hypertension is briefly reviewed. This matter is assuming new importance at present, given new data on the efficacy of normalization of blood pressure for adults with so-called "mild" hypertension (average diastolic 90-104 mm Hg), hence the need for safe nutritional-hygienic alternatives to years-long drug treatment for millions of people with such hypertension. Two trials by the authors deal with some unresolved questions in this area. The first, a preliminary study, involved 21 lacto-ovo-vegetarian high school students living in a boarding school. With decrease in daily Na intake from 216 to 72 meq for the experimental compared with the control group, red blood cell Na concentration was significantly lower in the former; systolic pressure was slightly but not significantly lower. The second trial, the Primary Prevention of Hypertension, involves over 200 hypertension-prone persons aged 30-44, and explores the ability in the experimental group to reduce blood pressure and prevent development of hypertension by safe nutritional-hygienic means (weight reduction, dietary Na decrease, avoidance of excess alcohol, rhythmic exercise). Initial results at 6 months are presented. Trials on the prevention and control of hypertension by nonpharmacologic means, including reduced Na intake, and involving analyses of the inter-relationships among dietary Na, other dietary factors, Na metabolism, and blood pressure in samples from different population strata, are an important present-day research need. 相似文献
