Abstract
Vitamin D (Vit D) deficiency has become a global health care issue, as it affects a great number of women during pregnancy and lactation. Vit D levels are critical during pregnancy, being the mother the only source of them for the developing fetus; an enzymatic system for conversion of 25OH VitD into 1-25(OH) 2 VitD is present in the placenta, thus reinforcing the importance of VitD during gestation. VitD deficiency has been associated with obstetric complications and adverse outcomes in offspring, affecting skeletal, immunological and respiratory systems. It is known that prenatal supplements available do not contain enough VitD to fulfil requirements. It is generally accepted that elevated PTH is an indicator of VitD deficiency, and Hysaj O et al (2021) showed that 25OH VitD is a statistically significant determinant of PTH levels in early and late pregnancy. Aim To evaluateVitD status and its relationship to parathyroid hormone (PTH) in a cohort of pregnant women representative of multiple Argentinian regions. Subjects and Methods Data from samples of 423 pregnant women in 1st and 2nd trimester were collected between 2016 and 2021. VitD was measured in different platforms: DiaSorin Liaison CLIA (n=184), Roche COBAS ECLIA (n=166), Abbott ARCHITECT CMIA (n=33), Biomérieux VIDAS ELFA (n=18) and Siemens CENTAUR CLIA (n=16). PTH (ng/L) was measured in 162 samples by SIEMENS IMMULITE CLIA and Roche COBAS ECLIA. As VitD is light-exposure dependent, we considered warm and high light-exposure season period from December to March and cold and low light season from April to September. VITD (ng/L) levels were classified as Deficient (<20), Insufficient (between 21 and 29) and Sufficient (>30) (Endocrine Society, 2014). Results From 423 data collected, 102 were excluded because of lacking information on VitD supplementation. From the remaining non supplemented 321 samples, 48% resulted insufficient, 30% deficient and 22% sufficient for VitD (groups comparison: p< 0. 05, Kruskal Wallis-Dunn test). The seasonal period and pregnancy trimester distributions didn't show significant differences. Similar results of VitD insufficiency were found in the major used platforms, regardless the seasonal period considered. PTH results expressed as median and interquartile range were (ng/L): 32. 0 (13.7-169. 0) in Deficient pregnancies (N=92), 23.7(13.3-88. 0) in Insufficient (n=50) and 18.7 (9.8-55.7) in Sufficient (n=20). Conclusions This study shows VitD inadequate levels in 78% in non-supplemented pregnancies, regardless season or measurement platform. Relative elevated levels of PTH were associated to pregnancies with VitD deficiency, evidenciating a regulatory role according to published data. To improve VitD status during pregnancy it would be advisable to pose new strategies for prenatal supplements developed by a multidisciplinary professional team. Presentation: No date and time listed

Abstract
Our objectives were to evaluate technical lignins for their antifungal properties against 3 molds and 1 yeast causing hay spoilage, and their ability to preserve ground high-moisture alfalfa hay nutritive value in vitro. In experiment 1, 8 technical lignins and propionic acid (PRP; positive control) were tested at a dose of 40 mg/mL. The experiment had a randomized complete block design (RCBD, 4 runs) and a factorial arrangement of 3 molds × 10 additives (ADV). The effects of the ADV on yeast were evaluated separately with a RCBD. Sodium lignosulfonate (NaL) and PRP were the only treatments with 100 ± 2.8% inhibition of fungi. In experiment 2, the minimum inhibitory concentration (MIC) for selected lignins and PRP were determined. At pH 4, NaL had the lowest MIC across the molds (20-33.3 mg/mL) and magnesium lignosulfonate (MgL) for the yeast (26.7) among the lignins. However, PRP had MIC values that were several-fold lower across all fungi (1.25-3.33). In experiment 3, a RCBD (5 blocks) with a 3 (ADV; NaL, MgL, and PRP) × 4 (doses: 0, 0.5, 1, and 3% wt/wt fresh basis) factorial arrangement of treatments was used to evaluate the preservative effects of ADV in ground high-moisture alfalfa hay inoculated with a mixture of the fungi previously tested and incubated under aerobic conditions in vitro. After 15 d, relative to untreated hay (14.9), dry matter (DM) losses were lessened by doses as low as 1% for NaL (3.39) and 0.5% for PRP (0.81 ± 0.77%). The mold count was reduced in both NaL at 3% (3.92) and PRP as low as 0.5% (3.94) relative to untreated hay (7.76 ± 0.55 log cfu/fresh g). Consequently, sugars were best preserved by NaL at 3% (10.1) and PRP as low as 0.5% (10.5) versus untreated (7.99 ± 0.283% DM), while keeping neutral detergent fiber values lower in NaL (45.9) and PRP-treated (45.1) hays at the same doses, respectively, relative to untreated (49.7 ± 0.66% DM). Hay DM digestibility was increased by doses as low as 3% for NaL (67.5), 1% MgL (67.0), and 0.5% PRP (68.5) versus untreated hay (61.8 ± 0.77%). The lowest doses increasing neutral detergent fiber digestibility relative to untreated hay (23.3) were 0.5% for MgL and PRP (30.5 and 30.1, respectively) and 1% for NaL (30.7 ± 1.09% DM). Across technical lignins, NaL showed the most promise as a potential hay preservative. However, its effects were limited compared with PRP at equivalent doses. Despite not having an effect on preservation, MgL improved DM digestibility by stimulating neutral detergent fiber digestibility. This study warrants further development of NaL under field conditions.

Abstract
The objectives were to evaluate (1) the use of 2 types of experimental silos (S) to characterize whole-crop oat (Avena sativa L.) silage with or without addition of an inoculant (I), and (2) the effect of inoculation on the microbial community structure of oats ensiled using only plastic bucket silos (BKT). From each of 6 sections in a field, oats were harvested, treated (INO) or not (CON) with inoculant, packed into 19-L BKT or vacuum bags (BG), and ensiled for 217 d. The inoculant added contained Lactobacillus buchneri and Pediococcus pentosaceus (4 × 105 and 1 × 105 cfu/g of fresh oats, respectively). The experimental design was a complete randomized design replicated 6 times. Treatment design was the factorial combination of 2 S × 2 I. Some differences existed between BG versus BKT at silo opening (217 d), including a decreased CP (7.73 vs. 7.04 ± 0.247% of DM) and ethanol (1.93 vs. 1.55 ± 0.155) and increased lactic acid (4.28 vs. 3.65 ± 0.241), respectively. Also, WSC and mold counts were reduced in BG versus BKT for CON (1.78 vs. 2.70 ± 0.162% of DM and 0.8 vs. 2.82 ± 0.409 log cfu/fresh g) but not for INO (∼1.53 and 1.55), respectively. Application of INO increased DM recovery (96.1 vs. 92.9 ± 0.63%), aerobic stability (565 vs. 133 ± 29.2 h), acetic acid (2.38 vs. 1.22 ± 0.116% of DM), and reduced NDF (65.0 vs. 67.0 ± 0.57), ADF (36.7 vs. 38.1 ± 0.60), ethanol (0.63 vs. 2.85 ± 0.155), and yeast counts (1.10 vs. 4.13 ± 0.484 log cfu/fresh g) in INO versus CON, respectively. At d 0, no differences were found for S and I on the nutritional composition and background microbial counts. Leuconostocaceae (82.9 ± 4.27%) and Enterobacteriaceae (15.2 ± 3.52) were the predominant bacterial families and unidentified sequences were predominant for fungi. A higher relative abundance of the Davidiellaceae fungal family (34.3 vs. 19.6 ± 4.47) was observed in INO versus CON. At opening (217 d), INO had a lower relative abundance of Leuconostocaceae (42.3 vs. 95.8 ± 4.64) and higher Lactobacillaceae (57.4 vs. 3.9 ± 4.65) versus CON. Despite several differences were found between BKT and BG, both techniques can be comparable for characterizing effects of INO on the most basic measures used in silage evaluation. The use of inoculant improved oat silage quality partially by a shift in the bacterial community composition during ensiling, which mainly consisted of an increased relative abundance of Lactobacillaceae and reduction of Leuconostocaceae relative to CON.

Abstract
Presented is a three-year study using a 15-methyl analogue of prostaglandin F2 alpha, in the management of severe postpartum hemorrhage due to uterine atony in patients who were unresponsive to conventional therapies. Fifty-four patients were entered into the study, but 51 were analyzed for efficacy. Successful control of postpartum hemorrhage occurred in 86%. Of the seven in whom therapy failed and who subsequently required surgical therapy, four had chorioamnionitis. Six subjects had intramyometrial injection of the agent, with dramatic results in five. Mild transient side effects occurred in less than 10% of subjects.

Abstract
Twenty patients with severe postpartum hemorrhage due to uterine atony who were unresponsive to conventional therapy were treated with 0.25-mg intramuscular injections of (15-S)-15-methyl prostaglandin F2 alpha-tromethamine. A rapid and successful response was obtained in 18 patients. Two patients required surgical procedures to control bleeding. Both patients with treatment failure had chorioamnionitis. Side effects of the prostaglandin therapy included nausea, vomiting and diarrhea, a transient mild temperature elevation, and a transient moderate blood pressure elevation. Those subjects with preeclampsia did not demonstrate a serious elevation of blood pressure. The prostaglandin F2 alpha analogue appears to be very effective in the treatment of postpartum hemorrhage due to uterine atony.

Abstract
The aim of the study was to evaluate the use of ultrasound biparietal diameter (BPD) in the timing of elective repeat cesarean section on a large indigent service. One hundred sixty-five patients were evaluated over 2 years. If the BPD was 9.3 cm or more at or later than 38 weeks' gestation, a repeat procedure was undertaken without further testing of fetal maturity. This occurred in 55% of the study group. None of these neonates developed hyaline membrane disease (HMD). The remainder of the study group either did not attain a BPD of 9.3 cm by term, were diabetic, or had other factors to determine timing of delivery. Of this group, 50% underwent amniocentesis for a lecithin:sphingomyelin ratio. Three patients had fetal bleeding, 1 had rupture of membranes, and 1 began labor following amniocentesis. All neonates were healthy except 1 who had mild HMD. That neonate had not reached 9.3 cm BPD. Ultrasound has allowed development of a management program for elective repeat cesarean section that is reliable, cost-effective, and beneficial to the mother and neonate.

Abstract
A double-blind placebo-controlled experiment was performed in 100 patients in labor with membrane rupture to determine the bacteriologic effects of antibiotic prophylaxis. Each subject received either 2.0 g cefamandole or placebo after cord clamping and 4 and 8 hours later. The cefamandole group had significantly less endometritis, but did not have significantly fewer major complications. Amniotic fluid cultures of the 2 groups were similar, but uterine lavage cultures of the cefamandole group showed significant increases in enterococci and gram-negative aerobes and decreases in gram-positive anerobes and low virulence organisms (Staphylococcus epidermidis, lactobacilli, and diphtheroids). Although clinical problems did not regularly accompany these changes, it would be foolhardy to ignore them. Thus, when patients develop infection after antibiotic prophylaxis, the physician should check for infection with resistant organisms.

Abstract
This prospective study presents a protocol for the treatment of premature labor with beta sympathomimetics and the results when isoxsuprine was used. Seventy-two patients from 25 to 36 weeks' gestation were treated. All patients were placed at bed rest, hydrated, and given parenteral sedation prior to the intravenous use of isoxsuprine. Treatment was continued via the intramuscular and oral routes until the thirty-seventh week of gestation. Three patients (4.2%) were delivered of infants during the initial infusion, and 15 (20.2%) were delivered of infants within 2 weeks after the onset of therapy. Forty-nine (68%) were delivered of infants after 37 weeks' gestation, and their infants weighed more than 2,500 grams. Maternal side effects were common, but none necessitated termination of therapy. There were six neonatal deaths, the causes of which were respiratory distress syndrome in two infants, necrotizing enterocolitis in one, group B streptococcal sepsis in one, congenital anomalies with sepsis in one, and multiple congenital anomalies in one.

Abstract
Acute chorioamnionitis has been recognized as a major threat to both mother and fetus, but there has been little study of its therapy. On this service, the plan of management consists of parenteral, broad-spectrum antibiotic therapy and prompt action to effect delivery. Cesarean section was generally performed only when there were additional obstetric indications. No arbitrary time limit was set for the diagnosis-to-delivery interval. The perinatal mortality rate was increased fourfold, but few deaths could be attributed to infection. Maternal outcome was usually good following vaginal delivery and more complicated following abdominal delivery. Over 90% of patients were delivered within 12 hours of diagnosis of chorioamnionitis.
