Nulliparous

PURPOSE: The aim of this article is to present our experience with minimally-invasive treatment for nulliparous patients with pelvic venous congestion syndrome (PVCS) with special attention to anatomical considerations, procedural and clinical outcome. MATERIALS AND METHODS: In this retrospective, monocentric study, 21 patients with PVCS treated from January 2014 to June 2023 were included. The preprocedural imaging evaluation of PVCS was based on color Doppler ultrasound, contrast-enhanced CT and/or MRI...

OBJECTIVE: Preventing adverse events due to unstable oxygen saturation (SpO2) at night in pregnant women is of utmost importance. Poor sleep has been demonstrated to impact SpO2 levels. Nowadays, many gravida have a habit of prolonged exposure to light before sleep, which can disrupt their sleep. Therefore, this study aimed at investigate the relationship between lights-out time, sleep parameters and SpO2, exploring the underlying mechanisms. METHODS: The data of 2881 eligible subjects from the Nulliparous Pregnancy Outcomes Study Monitoring Mothers-to-be and Sleep Disordered Breathing (nuMOM2b-SDB) database were analyzed...

BACKGROUND: A perineal tear is a rupture of the skin or muscle between the vagina and anus (perineum). A third-degree tear is one type of extended perineal tear (EPT), and it involves the penetration of the anal sphincter muscle. Another type of EPT is a fourth-degree laceration, which penetrates deeper into the lining of the anus or rectum. The stretching of the perineum during childbirth may result in perineal trauma. Invasive surgical interventions are required for the treatment of EPTs...

BACKGROUND Rapidly involuting congenital hemangioma (RICH) of the fetal skull is an extremely rare vascular disease which undergoes proliferation only in utero and progresses with maximal size at birth. RICH can be detected by prenatal imaging but is easily misdiagnosed. CASE REPORT A 28-year-old nulliparous woman was referred at 38 weeks of gestation for routine screening with obstetric ultrasonography. The ultrasonography revealed a female fetus with a previously undetected head tumor (32×22 mm). Certain unusual sonographic features were observed: the lesion was fusiform, with a wide base adjacent to the frontal bone...

INTRODUCTION: A variety of labor pain management options is essential to patients and their care providers. Inhaled, patient controlled nitrous oxide (N2 O) is a valuable addition to these options. The purpose of this study was to examine laboring patient, newborn, and provider characteristics associated with N2 O use for pain relief in labor and to examine the association between N2 O, conversion to neuraxial analgesia, and cesarean birth. METHODS: This was a retrospective observational cohort study of the first year of N2 O use in one large academic medical center...

BACKGROUND: Previous reports reveal inconsistent findings of right ventricular (RV) changes following pregnancy in subjects with repaired tetralogy of Fallot (rTOF). METHODS: A two-center, retrospective cohort study which included women with rTOF who completed pregnancy that were matched to nulliparous women with rTOF by age at the time of baseline cardiac magnetic resonance (CMR), RV ejection fraction (RVEF), and indexed RV end-diastolic volume (RVEDVi). Pre-pregnancy and postpartum cardiac magnetic resonance (CMR) were analyzed and compared to sequential CMR of nulliparous subjects with rTOF...

Background and Objectives : Pelvic floor muscles (PFM) play a core role in defecation and micturition. Weakening of PFM underlies urogynecological disorders such as pelvic organ prolapse and stress urinary incontinence. Vaginal delivery damages PFM. Muscle trauma implies an inflammatory response mediated by myeloid cells, essential for subsequent recovery. Molecular signaling characterizing the pro-inflammatory phase shifts M1 macrophages to M2 macrophages, which modulate muscle repair. The present study aimed to evaluate histological characteristics and the presence of M1 and M2 macrophages in bulbospongiosus (Bsm) and pubococcygeus muscles (Pcm)...

Objectives : The objective of this study was to evaluate the efficacy of lidocaine spray in reducing the pain during colposcopy-directed cervical biopsy (CDB). Methods : From December 2017 to February 2019, 312 women undergoing CDBs were enrolled. The participants were randomized to three groups: group 1 (lidocaine spray), in which lidocaine spray was applied thoroughly to the cervix; group 2 (placebo), in which normal saline was applied thoroughly to the cervix; and group 3 (control), in which no anesthetic agent was applied to the cervix...

Endometrial cancer is the most common gynecologic malignancy in developed countries, and the incidence is rising in premenopausal females. Type I EC is more common than Type II EC (80% vs. 20%) and is associated with a hyperestrogenic state. Estrogen unopposed by progesterone is considered to be the main driving factor in the pathogenesis of EC. Studies show that BMI > 30 kg/m2 , prolonged duration of menses, nulliparity, presence of polycystic ovarian syndrome, and Lynch syndrome are the most common causes of EC in premenopausal women...

Researchers have reported the benefits of feeding rumen-protected methionine (RPM) during the peripartum on the health parameters of dairy cows. Rumen-protected methionine has reportedly improved milk yield, milk components and liver health, but the literature is scarce on its effects in commercial herds. Therefore, we aimed to determine the effects of feeding RPMet (Smartamine M®, Adisseo Inc., Antony, France) prepartum (8 g per cow per day) and postpartum (15 g per cow per day) on performance, metabolic profile, and culling rate of Holstein cows in a commercial herd...

BACKGROUND: pregnancy-associated breast cancer (PABC) affects one in 3000 pregnancies, often presenting with aggressive features. METHODS: We retrospectively evaluated a cohort of 282 young BC patients (≤45 years old) treated between 1995 and 2019, dividing them into three groups: nulliparous women, women with PABC (diagnosed within 2 years since last pregnancy) and women with BC diagnosed > 2 years since last pregnancy. This last group was further stratified according to the time between pregnancy and BC...

BACKGROUND: Pregnancy Associated Malaria (PAM) include malaria in pregnancy (MiP), placental malaria (PM), and congenital malaria (CM). The evidence available in Colombia on PAM focuses on one of the presentations (MiP, PM or CM), and no study longitudinally analyses the infection from the pregnant woman, passing through the placenta, until culminating in the newborn. This study determined the frequency of MiP, PM, and CM caused by Plasmodium vivax, Plasmodium falciparum, or mixed infections, according to Thick Blood Smear (TBS) and quantitative Polymerase Chain Reaction (qPCR)...

BACKGROUND: Pacific Islander (PI) women in Australia have an increased risk of gestational diabetes (GDM); however, their perinatal outcomes are poorly understood. AIM: The aim was to determine the maternal characteristics and perinatal outcomes of PI women with and without GDM compared to Australian/European (AE)-born women. METHODS: A retrospective analysis of perinatal outcomes of singleton deliveries >20 weeks' gestation between 1 January 2011 and 31 December 2020 was conducted at a tertiary provider (Melbourne, Australia)...

Pelvic internal hernias, including pouch of Douglas hernias, are a very rare cause of small bowel obstruction. They pose a challenge in diagnosis due to their rarity and lack of specific radiological features. The definitive diagnosis is usually reached intraoperatively. The treatment consists of reduction with or without resection of the herniated bowel and primary repair of the defect. Mesh placement has been reported but is still arguable, as no musculofacial defect is involved. Here, we present a case of a 28-year-old female patient, a nulliparous with multiple medical conditions including familial Mediterranean fever (FMF) and an extremely rare tumor, peritoneal xanthogranuloma...

OBJECTIVE: To compare the risk of intrapartum cesarean delivery (CD) between patients with twin and singleton pregnancies undergoing a trial of labor and identify risk factors for intrapartum CD in twin pregnancies. METHODS: The present study was a retrospective cohort study of patients with a twin or singleton pregnancy who underwent a trial of labor at ≥340/7 weeks in a single center (2015-2022). The primary outcome was the rate of intrapartum CD. In twin pregnancies, this outcome was limited to CD of both twins...

BACKGROUND: Iodine nutrition is critical for fetal neurodevelopment in the first trimester of pregnancy, a period associated with dramatic changes in thyroid function. The aim of this study was to evaluate iodine nutritional status and thyroid function reference ranges in the first trimester in Taiwan. METHODS: Pregnant women aged 20 years and above in the first trimester were recruited in Taipei Veterans General Hospital, Taiwan from March 2019 to July 2022. Each participant provided a spot urine sample for measurement of urinary iodine concentration (UIC) and a blood sample for check-up of thyroid function and thyroid autoantibodies...

CONTEXT: The intrauterine device (IUD) is one type of long-acting reversible contraceptive that is becoming increasingly popular among patients and healthcare providers alike, though many are deterred from using this option due to pain or fear of pain with IUD insertion. While the IUD insertion process itself is standardized, the use of pain medication is not. There is a lack of research regarding provider preference in analgesic use for IUD insertion procedures, which analgesics are being provided to patients, and under which circumstances...

OBJECTIVE: Involvement of the lower urinary tract is found in 0.2-2.5% of all deep infiltrating endometriosis (DIE)1 , 2 . The bladder is the most affected organ with a prevalence of up to 80% of cases3 . Patients with bladder endometriosis are often symptomatic (dysuria, hyperactive bladder, recurrent urinary tract infections and hematuria). Surgery is the gold standard treatment for this condition when medical therapy fails1 , 2 . Several studies have shown the feasibility, effectiveness, and safety of the laparoscopic approach4 but data about robotic-assisted approach are missing in literature...

BACKGROUND: In malaria endemic regions of the Peruvian Amazon, rainfall together with river level and breeding site availability drive fluctuating vector mosquito abundance and human malaria cases, leading to temporal heterogeneity. The main variables influencing spatial transmission include location of communities, mosquito behaviour, land use/land cover, and human ecology/behaviour. The main objective was to evaluate seasonal and microgeographic biting behaviour of the malaria vector Nyssorhynchus (or Anopheles) darlingi in Amazonian Peru and to investigate effects of seasonality on malaria transmission...

IMPORTANCE: In young-onset breast cancer (YOBC), a diagnosis within 5 to 10 years of childbirth is associated with increased mortality. Women with germline BRCA1/2 pathogenic variants (PVs) are more likely to be diagnosed with BC at younger ages, but the impact of childbirth on mortality is unknown. OBJECTIVE: To determine whether time between most recent childbirth and BC diagnosis is associated with mortality among patients with YOBC and germline BRCA1/2 PVs. DESIGN, SETTING, AND PARTICIPANTS: This prospective cohort study included women with germline BRCA1/2 PVs diagnosed with stage I to III BC at age 45 years or younger between 1950 and 2021 in the United Kingdom, who were followed up until November 2021...
