RESUMEN

Background Out of the many causes of abruptio placentae, the micronutrient association with its occurrence and severity has not been researched extensively till now. We aim to measure the serum levels of homocysteine, folic acid and vitamin B12 in patients with abruptio placentae in the third trimester of pregnancy and compare the levels with those without the complication. We also propose to compare the feto-maternal outcome between the groups. Methods The cross-sectional study was undertaken in 50 pregnant women with abruption before or during delivery and 50 controls with uncomplicated pregnancy over 28 weeks of gestation. Serum levels of homocysteine, folic acid, and vitamin B12 were determined and feto-maternal outcome was compared between the groups Results Mean age of the cases and controls are 26.82 ± 5.5 and 28.82 ± 4.88 years respectively. Obstetric characteristics have significant difference between the groups in terms of gravidity, mode of delivery, timing of delivery, proportion of stillbirths and blood transfusion. The mean concentration of homocysteine and vitamin B12 between the groups also have a significant difference . The serum level of homocysteine is significantly correlated with serum vitamin B12 level (Pearson correlation= -0.601, P=0.000). However, folic acid concentration between the groups remains comparable. Conclusion Hence we conclude that vitamin B12 and homocysteine are significant determinants of abruptio placentae in pregnant women. Supplementation with the vitamin in the high-risk Indian population can avert a number of obstetric complications occurring due to raised homocysteine.

RESUMEN

The use of nanomaterials in medicine depends largely on nanotoxicological evaluation in order to ensure safe application on living organisms. Artificial intelligence (AI) and machine learning (MI) can be used to analyze and interpret large amounts of data in the field of toxicology, such as data from toxicological databases and high-content image-based screening data. Physiologically based pharmacokinetic (PBPK) models and nano-quantitative structure-activity relationship (QSAR) models can be used to predict the behavior and toxic effects of nanomaterials, respectively. PBPK and Nano-QSAR are prominent ML tool for harmful event analysis that is used to understand the mechanisms by which chemical compounds can cause toxic effects, while toxicogenomics is the study of the genetic basis of toxic responses in living organisms. Despite the potential of these methods, there are still many challenges and uncertainties that need to be addressed in the field. In this review, we provide an overview of artificial intelligence (AI) and machine learning (ML) techniques in nanomedicine and nanotoxicology to better understand the potential toxic effects of these materials at the nanoscale.

RESUMEN

Aim: The management of Premenstrual Syndrome (PMS) is still evolving due to the modest effect sizes of the available treatment modalities. Yoga as therapeutic intervention in PMS has been gathering interest amongst researchers. The current manuscript reviews the evidence surrounding yoga in PMS.Methods: This manuscript was a systematic review and meta-analysis evaluating the effectiveness of yoga on the total scores and sub-domains of PMS after studies were identified using a pre-defined selection criterion after a search in PubMed, Google Scholar, Scopus and Web of Science. Both quantitative and qualitative analysis of the accumulated data was performed. Overall, 14 studies were identified for the review, 11 of which were used for the purpose of quantitative analysis.Results: The studies were heterogenous in terms of the design, yoga regimes, nature of interventions and tools used for outcome measures. It was found that yoga was beneficial in the management of PMS. This benefit was also seen when all the sub-domains of PMS were individually examined except physical sub-domain.Conclusion: Though there were certain limitations in our review like heterogeneity in studies, possibility of publication bias and restrictive selection criterion; it supported that yoga can be beneficial in patients with PMS.

RESUMEN

We aim to evaluate the association between serum 25-hydroxyvitamin D3 levels and total number, volume and location of uterine fibroids (UFs) in premenopausal women in North Indian population. This case control study was undertaken in 310 women between 18 years and 45 years of age. Cases comprised of 102 women with fibroid lesion and the control group included 208 women with normal uterine morphology on ultrasonography. Blood samples were taken for measuring 25-hydroxyvitamin D3 levels. The mean serum 25-hydroxyvitamin D3 level in the study and control group was 14.52 ± 7.89 ng/mL and 26.6 ± 14.36 ng/mL respectively (p < 0.05). There was significant inverse correlation between serum 25-hydroxyvitamin D3 levels and total volume of fibroids (p = 0.000) while none between 25-hydroxyvitamin D3 levels with location, number of fibroids. 25-hydroxyvitamin D3 deficiency was more common in the study group (54.90%) compared to healthy controls (6.7%) while sufficiency was more common among controls (67.8% vs. 27.45) (p < 0.05). Women with deficient 25-hydroxyvitamin D3 levels have an odds of 18.36 for developing uterine fibroid. Women with low parity, those belonging to higher socioeconomic status and having less than 1-hour sun exposure per day were independently found to have high risk for development of UFs. Vitamin D may have a role in growth of UFs. Women not able to get adequate sun exposure due to indoor working conditions may need evaluation and supplementation as prophylaxis for development of fibroid.

RESUMEN

AIM: Copper containing IUCDs are one of most effective mode of contraception for birth spacing. We conducted this prospective observational study to suggest a possible better period of insertion of IUCDs with cost-saving benefits. METHODS: All married women in the reproductive age group desirous of Copper-T 375 IUD insertion in either immediate postplacental (PP), immediate postabortal (PA) or interval (INT) period were recruited. The women were asked to return for scheduled follow-up visits at 6 weeks, 6 months and 12 months. They were advised to visit family planning clinic any time if they experienced pelvic pain, discharge per vaginum, unusual bleeding or missed periods. At each visit, women were interviewed for any side effects they have experienced and were asked to elaborate. Pelvic pain was assessed from visual analogue scale. Continuation rate was measured at the end of one year. RESULTS: Women in INT group (90.14%) had the highest continuation rate followed by PP (83.18%) and PA (80%) groups. Women in PP (AOR = 3.37, 95% CI 1.17-9.72) and PA (AOR = 4.53, 95% CI 1.33-14.04) groups had higher odds of discontinuation compared to INT group after adjusting for age, parity, working and education status. There was a significant difference between the groups when cumulative expulsion was considered (p = 0.045), but none when cumulative removal (p = 0.107) was taken into account. CONCLUSION: The continuation rate remained high in women who had insertion in the interval period compared to immediate postplacental and postabortal periods.

RESUMEN

PURPOSE: We aim to determine the predictive value of endometrial thickness by transvaginal ultrasonography (TVS) in diagnosing endometrial pathology and to evaluate whether Doppler complements its diagnostic efficacy in perimenopausal women with abnormal uterine bleeding. METHODS: This cross-sectional observational study was conducted among 70 perimenopausal women with AUB who underwent TVS measurement of endometrial thickness (ET) and Doppler flow indices followed by endometrial sampling and histopathological examination (HPE). RESULTS: In HPE, 51 (73%) women had normal diagnosis while 19 (27%) women had neoplastic histology either benign or malignant. They were categorised into group I and group II, respectively. There was a significant difference in age (P=0.001) and incidence of obesity (P=0.01) between the two groups. The ETs measured in group I and group II were 7.89 ± 2.62 mm and 14.07 ± 3.96 mm, respectively, with significant difference (P < 0.001). A TVS-ET of 10.5 mm had the highest sensitivity and specificity of 89.5% and 86.3%, respectively, PPV of 70.68%, NPV of 95.68%, LR+ of 6.52, and LR- of 0.12. Doppler flow velocimetric study of endometrial and uterine vessels did not demonstrate a significant difference. CONCLUSIONS: Women in perimenopause with AUB should be offered to undergo endometrial sampling for histopathological examination if TVS ET ≥10.5 mm. The coexisting risk factors especially higher age (>45 years) and obesity (BMI>30) significantly escalate the chances of developing endometrial pathology.

RESUMEN

Aim: This study aims to determine the prevalence of Metabolic Syndrome (MS) and recognize its abnormal components in pre and postmenopausal women. We also aim to recognize the abnormal components in postmenopausal women with regard to duration since menopause. Materials and Methods: The cross-sectional study was undertaken among pre- and post-menopausal women between 40 and 65 years. Women with MS were identified as per the modified National Cholesterol Education Program Adult Treatment Panel III. Results: A total of 220 women were enrolled comprising 112 premenopausal and 108 postmenopausal women, the prevalence of MS among them being 33% and 51.85%, respectively. Postmenopausal status was found to be independently associated with MS when adjusted for potential confounders (adjusted odds ratios = 14.77, 95% confidence intervals: 1.77-23.33). All the components were proportionately higher in postmenopausal group, the rise in blood pressure (BP) (P = 0.003) and low high-density lipoprotein (HDL) (0.027) being statistically significant. The risk of MS, abdominal obesity, and high BP were highest in <5 years since menopause and decreased thereafter. The risk for low HDL and high triglyceride increased with the number of years since menopause, reaching the peak level in the 5-9-year group and then decreased while the risk of high fasting blood sugar increased reaching peak in the 10-14 years' group. Conclusion: The prevalence of MS is significantly high in postmenopausal women. Screening of women in premenopausal period will give an opportunity to intervene and prevent the menace of MS in Indian women predisposed to abdominal obesity, insulin resistance, and cardiovascular adverse events.

RESUMEN

OBJECTIVE: We aimed to evaluate the relation between plasma ascorbic acid levels and the occurrence of preterm premature rupture of membranes (PPROM) and whether patients with ascorbic acid deficiency have predisposition to microbial invasion, as revealed by serum interleukin-6 (IL-6) levels and confirmed by placental culture sensitivity evaluation. METHODS: This controlled study involved 50 women with PPROM at gestational age between 28 and 36.6 weeks. Fifty patients with uncomplicated pregnancy and intact membranes were observed as control group. Serum ascorbic acid and IL-6 levels were evaluated for PPROM group subjects and controls, matched by their gestational age and body mass index. Repeat samples for IL-6 were taken after 48 hours of admission in PROM group subjects and at the onset of labor in controls. Placental membranes were sent for culture sensitivity evaluation after delivery. RESULTS: The mean plasma level of ascorbic acid was 0.60±0.35 mg/dL and 1.18±0.43 mg/dL in the PPROM and control groups, respectively, showing significant difference. Plasma IL-6 level rose from 18.18±5.94 pg/mL to 34.32±7.31 pg/mL after 48 hours of admission in the PPROM group (P=0.000). Plasma IL-6 level in controls rose from 5.59±4.36 pg/mL at admission to 7.36±3.67 pg/mL at the onset of labor. Membrane culture test results were positive in a total of 40 samples, of which 37 samples were from the PPROM group subjects. CONCLUSION: Vitamin C deficiency, when complemented with elevated serum IL-6 level, can predict susceptibility to PPROM in the third trimester; the risk increases in women with prior history of similar pathology.

RESUMEN

OBJECTIVES: A chylomicron-mimicking lipid emulsion was prepared and loaded with paclitaxel (paclitaxel-CM) and was further grafted with galactose (paclitaxel-GCM) using palmitoyl-galactosamine, which was synthesized by reacting galactosamine hydrochloride with N-hydroxy succinimide ester of palmitic acid. Palmitoyl-galactosamine was used as a ligand for asialoglycoprotein receptors. METHODS: The uptake characteristics of the emulsions were evaluated in HepG-2 cells (human hepatocarcinaoma), which express asialoglycoprotein receptors, and MCF-7 (breast cancer) cells, which are devoid of these receptors. KEY FINDINGS: The incorporation efficiency of paclitaxel-CM was 68.05 +/- 4.80% and that of paclitaxel-GCM was 72.10 +/- 3.93% when the emulsion was prepared with 7.5% (w/w) paclitaxel/lipid phase. The globule size of paclitaxel-GCM and paclitaxel-CM was 124 +/- 8.67 and 96.45 +/- 5.78 nm, respectively. The release of paclitaxel from both of the formulations was fairly sustained: 50 +/- 3.2% of paclitaxel in 24 h. The cytotoxicity and uptake of paclitaxel-GCM were significantly higher (P < 0.05) in HepG-2 cells than MCF-7 cells, while for paclitaxel-CM cytotoxicity and uptake were similar in the two cell lines. This study clearly demonstrates that upon surface modification palmitoyl-galactosamine remains an integral part of the formulation. Paclitaxel solubility can be improved using optimum paclitaxel/lipid phase ratios. The paclitaxel-GCM formulation recognizes asialoglycoprotein receptors overexpressed on HepG-2 cells. CONCLUSIONS: Under our experimental conditions, the proposed paclitaxel-GCM formulation is an ideal delivery vehicle for specific targeting to liver cancer cells, which is anticipated to result in improved efficacy and reduced toxicity to normal cells.
