Vitamin A levels in premenstrual syndrome.

To determine whether changes in peripheral vitamin A levels are associated with symptoms of premenstrual syndrome (PMS), 10 PMS patients and 10 controls were studied. They gave blood at 2- or 3-day intervals through three menstrual cycles. The vitamin A was measured by fluorometry after cyclohexane extraction. In the controls, vitamin A values were 68.0 +/- 3.2 micrograms/dL (mean +/- SE) during the luteal phase and 69.8 +/- 4.2 micrograms/dL during the follicular phase. No significant changes were noted between the two values. In the patients, the values were 73.9 +/- 4.2 micrograms/dL during…

A Phase I/II Multicenter, Open-Label Study of the Oral Histone Deacetylase Inhibitor Abexinostat in Relapsed/Refractory Lymphoma.

PURPOSE: Additional targeted therapeutics are needed for the treatment of lymphoma. Abexinostat is an oral pan-histone deacetylase inhibitor (HDACi) displaying potent activity in preclinical models. We conducted a multicenter phase I/II study (N = 55) with single-agent abexinostat in relapsed/refractory lymphoma. EXPERIMENTAL DESIGN: In phase I, 25 heavily pretreated patients with any lymphoma subtype received oral abexinostat ranging from 30 to 60 mg/m(2) twice daily 5 days/week for 3 weeks or 7 days/week given every other week. Phase II evaluated abexinostat at the maximum tolerated dose in

Premenstrual dysphoric disorder (PMDD) demonstrates predictable, cyclic, affective and somatic symptoms that are aggravated in the late lute … bition, behavior activation, depression, anxiety, and irritability were assessed in both luteal and follicular phases. Results: The odds ratio of women with GAD having PMDD was 7.65 (95% CI: 1.69-34.63) in relation to those without it. This association was partially mediated by behavior inhibition and irritability and was completely mediated by depression. Women w …

Improved surgical outcomes in adenomyosis: a novel insight into the superiority of secretory phase adenomyomectomy.

OBJECTIVE: To evaluate whether the timing of adenomyomectomy within the menstrual cycle influences outcomes in patients with adenomyosis, and to assess whether surgery performed during the secretory phase offers clinical advantages over the proliferative phase. METHODS: We conducted a retrospective cohort study of patients with histologically confirmed adenomyosis who underwent uterus-sparing adenomyomectomy at our institution between January 2021 and April 2024. Patients were categorized according to the menstrual phase at the time of surgery: secretory phase and proliferative phase. The pri

Oral contraceptives maintain a very thin endometrium before operative hysteroscopy.

OBJECTIVE: To show that early follicular-phase administration of an oral contraceptive pill (OC) consistently provides a thin endometrium, as determined by transvaginal ultrasound. This is an ideal condition when performing operative hysteroscopy. DESIGN: Retrospective chart review of patients who have undergone ultrasound evaluation of the endometrial thickness under different hormonal conditions. Endometrial measurement was obtained during menstruation, in the late follicular phase, and in the luteal phase in 20 patients. In another group of 100 patients, endometrial measurement was made on…

The luteinizing hormone pulsatile secretion: diurnal excursions in normally cycling and postmenopausal women.

While numerous investigations have determined characteristics of episodic luteinizing hormone (LH) secretion in women, any diurnal LH rhythmicities during eugonadal and hypogonadal states have not been accurately addressed. Accordingly, blood was sampled at 15-min intervals for 24 h in 45 normally cycling women (16 early follicular (EFP), 14 late follicular (LFP), 15 mid-luteal phase (MLP) women) and in eight postmenopausal women (PMW). Pulse attributes (amplitudes, interpulse intervals) determined in the LH secretory profiles were fitted to cosinor functions to assess diurnal variabilities. I

Emotion and birth control: Emotion regulation ERPs differ based on menstrual cycle phase and hormonal contraceptive use.

While hormonal contraceptives (HCs) like oral contraceptive pills (OCs) and intrauterine devices (IUDs) can reportedly influence mood, the e … ulation processing. NC participants had a lower LPP amplitude in the mid-luteal compared to the mid-follicular phase. Reactivity to negative emotional stimuli decreased over time in the mid-luteal phase, whereas the HC groups showed sustained LPP activation. Reappraisal led only to significant LPP changes in the mid-follicular phase, and not in the mid-luteal phas …

Changes in the gonadotropin-releasing hormone pulse generator activity during the estrous cycle in the goat.

The hypothalamic GnRH pulse generator activity, which was assessed by the characteristic increases in the multiple unit activity (MUA) specifically associated with the pulsatile LH secretion (MUA volleys), was monitored throughout the estrous cycle of the female goat. Blood samples were collected daily for analysis of progesterone, estradiol and LH levels to monitor ovarian cyclicity. The frequency of the MUA volleys showed a reciprocal relationship with the plasma progesterone profile; being low during the luteal phase, whereas increased during the follicular phase until the onset of the subs…

Sex steroid hormones and circulating IgE levels.

The possible influence of sex steroid hormones on circulating IgE levels in general and IgE anti-Candida antibodies in particular was studie … d in gonadal dysgenetics, circulating progesterone levels were similar to those of women during the follicular phase (i.e., lower than in the luteal phase or in pregnancy), but the IgE levels were not different. The apparently low levels of IgE during the luteal phase may therefore be due to physiological factors other than fluctuations in the sex steroid hormones …

The effects of oral micronized progesterone on smoked cocaine self-administration in women.

There are currently no FDA-approved pharmacotherapies for cocaine abuse. Converging preclinical and clinical evidence indicates that progesterone may have potential as a treatment for cocaine-abusing women, who represent a growing portion of cocaine users. We have previously shown that oral progesterone reduced the positive subjective effects of cocaine in female cocaine users during the follicular phase of the menstrual cycle, when endogenous progesterone levels were low. To extend these findings, the present study assessed the effects of oral progesterone (150 mg BID) administered during the…
