Fetal Neuroprotective Mechanism of Maternal Magnesium Sulfate: Proteomic Analysis.

Mg supplementation has been shown to protect preterm fetuses from white and gray matter damage, but the mechanism is unclear. The purpose of this study was to study the effect of maternal inflammation on the overall protein panel of the fetal rat brain, as well as the neuroprotective effect of magnesium-sulfate (MG). Pregnant rats at e20 (n = 6, 18 total) received injections of i.p. lipopolysaccharide (LPS) 500 ug/kg or control saline (SAL) at time 0. Dams were randomized to treatment with s.c. MG (270 mg/kg loading followed by 27 mg/kg q20 min) or saline (SAL) from -2 to +2 h, followed by an additional injection of MG (270 mg/kg) at +2 h. At 4 h after LPS administration, fetal brains were collected from the 3 treatment groups (LPS/SAL, LPS/MG, SAL/SAL) and analyzed by proteomic technique. LPS significantly decreased fetal brain complement C3, alpha-1-antiproteinase, metallothionein-3, alpha-2-macroglobulin, neurosecretory protein VGF, glutathione S-transferase mu 2, fam91a1, cnot7, mitogen-activated protein kinase levels, and significantly increased fetal brain Hbg1, while MG treatment normalized these measures to normal values. Maternal inflammation may cause brain injury via pathways other than the activation of neurotoxic cytokines; this effect could be due to increased/decreased production of certain proteins associated with securing oligodendrocytes, encouraging neuronal growth in the brain, or protecting against cerebral ischemia. MG's neuroprotective activity may be achieved by modifying the effect of LPS on proteins involved in early brain development.

The Efficacy and Safety of CO2 Laser Treatment for Sexual Function and Vaginal Laxity Improvement in Pre-Menopausal Women.

BACKGROUND AND OBJECTIVES: Vaginal laxity lacks standardized diagnosis and severity criteria. It is considered as a subjective complaint that reflects decreased sexual satisfaction due to vaginal loosening. Treatment modalities have included physiotherapy and plastic surgery. Recently, laser treatments have also gained popularity as a means of relieving gynecological complaints such as pelvic organ prolapse, stress urinary incontinence, and genitourinary syndrome of menopause. The aim of the current study was to evaluate the efficacy of CO2 laser treatment in women for whom a decrease in sexual sensation during intercourse and vaginal loosening were their primary complaints. STUDY DESIGN/MATERIALS AND METHODS: For this prospective study, women with reported vaginal laxity and decreased sensation during intercourse were recruited from the Sexual Dysfunction Clinic in our health care campus. Each participant received three outpatient treatments with laser therapy, according to the same protocol. Treatment efficacy was assessed by changes in the Vaginal Health Index (VHI) and Female Sexual Function Index (FSFI). RESULTS: Overall, 84 pre-menopause women, with a mean age of 47.7 years, were included in the study. Mean VHI and FSFI were increased significantly at 3 months post-treatment and decreased again at 6 months post-treatment: 11.8 ± 1.6, 13.5 ± 1.1, and 11.8 ± 1.2, respectively, P = 0.013; and 21.3 ± 1.7, 29.9 ± 1.6, and 22.5 ± 1.8, respectively, P = 0.022. The rate of sexual intercourse doubled during the period of maximal treatment effect (P < 0.0001). CONCLUSIONS: CO2 laser treatment has both a statistically and clinically significant effect on participants' complaints and sex-life, which wanes by 6 months post-treatment. Laser therapy seems to be safe in the short term, with no serious adverse events reported in the current study. Further studies are warranted to determine the long-term safety and the efficacy of maintenance laser treatments. Lasers Surg. Med. © 2020 Wiley Periodicals LLC.

Fetal neuroprotective mechanism of maternal magnesium sulfate for late gestation inflammation: in a rodent model.

Background: Maternal administration of magnesium sulfate (Mg) is used in humans to protect the fetal brain during preterm delivery. We sought to determine the neuroprotective mechanism of Mg in a rat model of late gestation maternal inflammation.Methods: Pregnant rats at 20 d of gestation (20 total, four groups, N = 5 in each group) received i.p. LPS or saline. Dams were randomized for s.c. saline or Mg supplementation 2 h prior and following the LPS/saline injections. Dams were sacrificed 4 h following the last treatment. Fetal brains were collected from the four treatment groups. Fetal brain caspase 3 active form, NF-kB p65, neuronal nitric oxide synthase (phospho-nNos), and proinflammatory cytokines levels were determined by western blot.Results: Maternal LPS at e20 significantly (p < .01) increased fetal brain caspase 3 active form (af) (0.27 ± 0.02 versus 0.15 ± 0.06u), NFkB (0.23 ± 0.01 versus 0.13 ± 0.01u), and phospho-nNOS (0.22 ± 0.01 versus 0.12 ± 0.01u) and fetal brain proinflammatory cytokines (IL-6 0.21 ± 0.01 versus 0.11 ± 0.01 u; TNFα 0.29 ± 0.01 versus 0.15 ± 0.01u), compared with control fetuses. Mg treatment significantly (p < .05) reduced fetal brain caspase 3 af (0.16 ± 0.01u), NFkB p65 (0.11 ± 0.01u), phospho-nNOS (0.1 ± 0.01u), as well as brain proinflammatory cytokines (IL-6 0.07 ± 0.01u; TNFα 0.15 ± 0.01u) to levels similar to controls.Conclusion: Maternal inflammation-induced fetal brain injury at late gestation may be mediated by the activation of inflammatory response, oxidative stress, and apoptosis. Maternal Mg may attenuate the injury by inhibition of these putative pathways.

The safety and efficacy of CO2 laser in the treatment of stress urinary incontinence.

INTRODUCTION AND HYPOTHESIS: Conservative treatment is recommended as first-line therapy for stress urinary incontinence (SUI). We hypothesized that CO2 laser treatment would demonstrate safety and efficacy for women with SUI. METHODS: A prospective, open-label, cohort study of 33 women (mean age 43 years) referred from a continence clinic after urologist/urogynecologist assessment, with a verified stress urinary incontinence diagnosis based on urodynamic testing. The participants completed three outpatient treatments with laser therapy and were subsequently evaluated at 1, 3 and 6 months. The independent t and chi-square tests were used to assess changes in sanitary pad usage and SUI symptoms. RESULTS: Sanitary pad usage decreased from a median of 12 per day at baseline to 7 at 1-3 months post-treatment (P < 0.0001) and returned to 12 at 6 months post-treatment. Scores on the Urogenital Distress Inventory and the International Consultation of Incontinence Questionnaire decreased (improved) significantly at 1-3 months post-treatment: from 45 ± 2 and 16 ± 4, respectively, to 29.3 ± 14.7 and 8.15 ± 3.1, respectively (P < 0.0001). The scores returned to levels similar to baseline at 6 months after treatment. Participants reported mild and transient side effects, with significant improvement in quality of life. CONCLUSIONS: Laser therapy can be an optional conservative treatment for women who seek minimally invasive non-surgical treatment for the management of SUI. No serious adverse effects were reported though the sample size was not large, a possible limitation of the study. Further large randomized control trials are needed to appraise the efficacy and safety of laser therapy for stress urinary incontinence and to demonstrate the ultimate utility of this modality.

Characteristics and Outcomes of Ptyalism Gravidarum.

BACKGROUND: Ptyalism gravidarum (PG) is a condition of hypersalivation that affects pregnant women early in gestation. Symptoms include massive saliva volumes (up to 2 liters per day), swollen salivary glands, sleep deprivation, significant emotional distress, and social difficulties. OBJECTIVES: To examine maternal and fetal characteristics and pregnancy outcomes of patients with PG. METHODS: Patients diagnosed with PG in our clinic during the years 2001-2016 were identified and contacted. Demographic data were extracted from patient charts and clinical and outcome data was collected via telephone interviews. RESULTS: The incidence of PG was 1/963 (0.09%) in our sample. Eleven out of 22 women (40%) with PG were also diagnosed with hyperemesis gravidarum. Fetal gender did not increase the risk. Of the mothers presenting with PG, 37% had a positive family history for this condition. There was no associated increase in the rate of fetal or maternal complications. Two women reported a resolution of the symptoms immediately following hypnosis with acupuncture treatment. CONCLUSIONS: Although PG represents an unpleasant mental and physical condition, it does not pose any specific risk to the health of the mother or increase adverse perinatal outcomes for the fetus. Alternative medicine could play a role in the treatment of PG.

The effect of maternal hyperoxygenation on fetal circulatory system in normal growth and IUGR fetuses. What we can learn from this impact.

PURPOSE: The objectives of study were to assess and compare the effects of maternal hyperoxygenation on fetal circulation, in fetuses with intrauterine growth retardation and normal fetal growth. METHODS: Twelve singleton pregnant women with normal fetal growth and 12 singleton pregnant women with intrauterine growth restriction were recruited. Mean gestational age of 35.2 ± 3.5 and 34.7 ± 3.9 weeks, respectively. Doppler blood flow velocity waveforms were obtained from the middle cerebral artery, umbilical, main and proximal right pulmonary arteries. Pulsatility indices were calculated for all the vessels. Peak systolic velocity was determined for the middle cerebral artery. Following baseline measurements; each woman received 70% humidified oxygen for 10 min. Doppler measurements were then repeated. RESULTS: The pulsatility index in the middle cerebral artery increased significantly from 1.5 ± 0.27 to 1.88 ± 0.48, respectively (p = .006) in the high-risk group. However, it did not change significantly in the low-risk group. Hyperoxygenation caused a significant decrease in pulsatility indices in the pulmonary arteries for both groups. CONCLUSIONS: Hyperoxygenation interrupts the relative brain-sparing effect in the intrauterine growth retardation group, but it did not significantly change the pulsatility index of the middle cerebral artery in fetuses with adequate weight. The pulsatility index in the pulmonary arteries decreased significantly following hyperoxygenation.

Comparison between Lornoxicam and Paracetamol for Pain Management after Dilation and Curettage for Abortion.

BACKGROUND: Management of postoperative pain has become a growing concern, even for minor gynecological procedures. Proper postoperative pain management has been shown to lead to earlier mobilization, shortened hospital stay, and increased patient satisfaction. The optimal means of reducing the pain of pregnancy termination has not yet been determined. OBJECTIVES: To compare the efficiency in pain management of two drugs, lornoxicam and paracetamol, given intravenously postoperatively to women who underwent abortion with dilation and curettage. METHODS: The cohort comprised 80 women scheduled for dilation and curettage for pregnancy termination at 6-12 gestational weeks. The anesthesiologist gave 1000 mg paracetamol or 20 mg lornoxicam soon after starting the procedure, according to a randomization table. The medical staff and the patients were blinded to the drug that was administered. Pain levels were evaluated by a 10 cm visual analogue scale (VAS) at 15, 30, 60, 90, and 120 minutes following arrival at the postoperative care unit. RESULTS: Mean levels of pain decreased from 60 minutes postoperative until the end of recording, reaching minimum levels at 120 minutes: 0.8 ± 0.19 and 1.5 ± 0.28, for lornoxicam and paracetamol, respectively. The differences between the groups were statistically significant (P < 0.05 from 60 minutes after the procedure until the time of discharge. CONCLUSIONS: Compared to women who received paracetamol, women who received lornoxicam after dilation and curettage for termination of pregnancy reported lower levels of pain, from 30 minutes postoperative until the time of discharge following the procedure.
