Identifications of Similarity Metrics for Patients With Cancer: Protocol for a Scoping Review.

Background: Understanding the similarities of patients with cancer is essential to advancing personalized medicine, improving patient outcomes, and developing more effective and individualized treatments. It enables researchers to discover important patterns, biomarkers, and treatment strategies that can have a significant impact on cancer research and oncology. In addition, the identification of previously successfully treated patients supports oncologists in making treatment decisions for a new patient who is clinically or molecularly similar to the previous patient.

Attitudes and Acceptance Towards Artificial Intelligence in Medical Care.

Background: Artificial intelligence (AI) in medicine is a very topical issue. As far as the attitudes and perspectives of the different stakeholders in healthcare are concerned, there is still much to be explored.

Objective: Our aim was to determine attitudes and aspects towards acceptance of AI applications from the perspective of physicians in university hospitals.

[Prostaglandin content in decidual tissue of women in spontaneous abortion].

Prostaglandins E2 and F2 alpha were measured in decidual tissue of women after spontaneous abortions at pregnancy terms 8 to 10 weeks and after abortions induced by sulprostone, a synthetic prostaglandin E2 analog, at pregnancy term 4-5 weeks. Women in whom pregnancy was terminated surgically at relevant periods were controls. Prostaglandin E2 concentration was found to be 5 times higher and that of prostaglandin F2 alpha 40 times higher in women with spontaneous abortions than in surgical abortion.

The effect of RU486 on progesterone and oestrogen receptor concentration in human decidua on early pregnancy.

Concentrations of progesterone receptor (PR) and oestrogen receptor (ER) were measured by radioligand assay in decidual tissue of women undergoing termination of early pregnancy (amenorrhoea up to 49 days). Pregnancies were terminated by vacuum aspiration at 12 or 36 h after oral administration of placebo or antiprogestin RU486 in different doses. Treatment with RU486 decreased decidual PR content, the effect being observed at 12 h as well as at 36 h after 600 mg RU486 and at 36 h after 3 x 25 mg RU486 given at 12 h intervals.

[The luliberin test as a criterion for assessing the prospect of stimulating ovulation with pergonal].

Differentiated clinico-hormonal investigation using diagnostic LH-RH testing made it possible to reveal various conditions of patients with hypogonadotropic amenorrhea. The expression of clinical signs of hypoestrogenemia corresponded to a degree of hormonal insufficiency. The investigation permitted the evaluation of the prospects of perganol-stimulated ovulation and a choice of an optimum initial drug dose.

[Epidemiology of induced abortion and contraception].

This article describes prevalence and distribution patterns of induced abortion and contraception in various regions of the USSR. Selective studies have elucidated a spectrum of factors of abortion and contraception prevalence, their roles in birth control and priorities in implementation of updated methods of induced abortion prevention.

[The effect of the synthetic analog of prostaglandin E2 sulprostone on the adenylate cyclase system in decidual tissue of women].

Activities of adenylate cyclase and phosphodiesterase were studied in decidual tissue of women, pregnancy of which was interrupted within the first term by means of synthetic analogue of prostaglandin E2 sulprostone; decidual tissue obtained after surgical abortion served as a control. Content of cAMP in decidual tissue was decreased 4-fold after administration of sulprostone. At the same time, activity od adenylate cyclase was decreased 2-3-fold, while activity of phosphodiesterase was unaltered.

[Comparative analysis of fertile and infertile cycles during stimulation of ovulation with pergonal in patients with hypo- gonadotropic amenorrhea].

A comparative assessment of variations in sex hormone levels and echographic parameters of fertile and infertile cycles was carried out in patients with gonadotrophic deficiency during pergonal induction of the ovulation. It was demonstrated that 83% of the infertile cycles were the first stimulation cycles. Basic differences were identified in the variation of sex hormone levels and echographic parameters of target organs between the fertile and infertile cycles.

[Changes in arterial blood pressure of women using hormonal contraceptives in relation to their cardiovascular history].

The revealed correlation of blood pressure variation in the females who had used hormonal contraceptives and certain features of their cardiovascular histories were used to define the group of risk for borderline arterial hypertension during the intake of Ovidon or Non-Ovlon and to develop the criteria for differentiated choice of estrogen-gestagen drugs.

Randomized comparison of different prostaglandin analogues and laminaria tent for preoperative cervical dilatation. World Health Organization Special Programme of Research, Development and Research Training in Human Reproduction: Task Force on Prostaglandins for Fertility Regulation.

In an eleven-centre study, 627 nulliparous subjects in the 8th to 12th week of gestation admitted for termination of pregnancy were allocated to one of five treatments to induce pre-operative cervical dilatation. The treatments were: 0.5 mg PGE2 methyl sulphonylamide; 1.

Use of different prostaglandin analogues for terminating pregnancy at different terms.

The abortifacient effect has been compared of 15 me-PGF2 alpha, ONO 802 and 16 phenoxy-w-17,18,19,20-tetranor PGE2 given intra-muscularly, intravaginally and with or without laminaria dilatation of the cervix. Locally administered, 15 me-PGF2 alpha, proved to be more efficient than ONO 802. Laminaria had a beneficial effect on dilatation.
