Using augmented reality in molecular case studies to enhance biomolecular structure-function explorations in undergraduate classrooms. JOURNAL OF MICROBIOLOGY & BIOLOGY EDUCATION 2024:e0001924. [PMID: 38624224 DOI: 10.1128/jmbe.00019-24] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/01/2024] [Accepted: 03/15/2024] [Indexed: 04/17/2024]
Abstract
Molecular case studies (MCSs) are open educational resources that use a storytelling approach to engage students in biomolecular structure-function explorations, at the interface of biology and chemistry. Although MCSs are developed for a particular target audience with specific learning goals, they are suitable for implementation in multiple disciplinary course contexts. Detailed teaching notes included in the case study help instructors plan and prepare for their implementation in diverse contexts. A newly developed MCS was simultaneously implemented in a biochemistry and a molecular parasitology course at two different institutions. Instructors participating in this cross-institutional and multidisciplinary implementation collaboratively identified the need for quick and effective ways to bridge the gap between the MCS authors' vision and the implementing instructor's interpretation of the case-related molecular structure-function discussions. Augmented reality (AR) is an interactive and engaging experience that has been used effectively in teaching molecular sciences. Its accessibility and ease-of-use with smart devices (e.g., phones and tablets) make it an attractive option for expediting and improving both instructor preparation and classroom implementation of MCSs. In this work, we report the incorporation of ready-to-use AR objects as checkpoints in the MCS. Interacting with these AR objects facilitated instructor preparation, reduced students' cognitive load, and provided clear expectations for their learning. Based on our classroom observations, we propose that the incorporation of AR in MCSs can facilitate its successful implementation, improve the classroom experience for educators and students, and make MCSs more broadly accessible in diverse curricular settings.

Is a Higher Amniotic Fluid Viral Load Associated with a Greater Risk of Fetal Injury in Congenital Cytomegalovirus Infection-A Systematic Review and Meta-Analysis. J Clin Med 2024; 13:2136. [PMID: 38610901 PMCID: PMC11012373 DOI: 10.3390/jcm13072136] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2024] [Revised: 03/28/2024] [Accepted: 03/30/2024] [Indexed: 04/14/2024] Open
Abstract
Background: Numerous studies have aimed to predict prenatal and neonatal outcomes for pregnancies complicated by congenital cytomegalovirus (CMV). Presently, assessing CMV severity prenatally relies largely on fetal imaging. A controversy exists regarding CMV viral load (VL) and its association with fetal and neonatal sequelae. Objective: To perform a systematic review and meta-analysis investigating the association between CMV DNA VL in amniotic fluid and fetal and neonatal outcomes in pregnancies with congenital CMV. Results: All cohort, case-control and observational studies that compared outcomes of fetuses with congenital CMV and provided information on individual patient CMV VL quantified in copies per milliliter (c/mL) from inception to January 2023 were included, with no geographical or language restrictions. A total of 1251 citations were reviewed with eight studies meeting inclusion criteria and included in meta-analysis. Affected pregnancies had a higher VL in the amniotic fluid compared to those unaffected with a mean difference of 2.2e+7 (range 1.5e+7 to 2.8e+7). In subgroup analysis, the VL was significantly higher in the fetuses, with imaging findings related to CMV compared to asymptomatic fetuses with a mean difference of 4.1e+7 (95% CI 2.8e+7-5.4e+7). However, among babies with congenital CMV, the VL was not significantly different between symptomatic and asymptomatic babies. Conclusions: Amniotic fluid CMV VL is associated with fetal sequalae in congenital CMV, with a higher VL conferring a greater risk for prenatal injury.

Abstract
ABSTRACT In the present study patients with previously diagnosed MRI-negative temporal lobe epilepsy (TLE) on long-term video electroencephalography (VEEG) monitoring were re-evaluated with high resolution 3T MRI brain to look out for a skull base temporal lobe encephalocoele (TE). A total of 234 VEEGs were analyzed. TLE had been diagnosed in 104 patients based on semiology, ictal, interictal EEG data, and brain positron emission tomography (PET) studies. Of these, 99 patients had temporal lobe abnormality (78 had mesial temporal sclerosis, 8 had tumor, 3 had focal cortical dysplasia, and 10 had mixed pathology). Out of the five 1.5T MRI-negative TLE patients, two patients were diagnosed with TE on subsequent 3T MRI brain scans and one patient underwent electrocorticography-guided tailored resection for complete removal of epileptogenic tissue; with Engels class I seizure freedom at one year follow-up. We propose that TE should be carefully searched for, as a cause of refractory TLE, using high-resolution MRI sequences.

Abstract
OBJECTIVE To evaluate the quality of ChatGPT responses to common issues in obstetrics and assess its ability to provide reliable responses to pregnant individuals. The study aimed to examine the responses based on expert opinions using predetermined criteria, including "accuracy," "completeness," and "safety." METHODS We curated 15 common and potentially clinically significant questions that pregnant women are asking. Two native English-speaking women were asked to reframe the questions in their own words, and we employed the ChatGPT language model to generate responses to the questions. To evaluate the accuracy, completeness, and safety of the ChatGPT's generated responses, we developed a questionnaire with a scale of 1 to 5 that obstetrics and gynecology experts from different countries were invited to rate accordingly. The ratings were analyzed to evaluate the average level of agreement and percentage of positive ratings (≥4) for each criterion. RESULTS Of the 42 experts invited, 20 responded to the questionnaire. The combined score for all responses yielded a mean rating of 4, with 75% of responses receiving a positive rating (≥4). While examining specific criteria, the ChatGPT responses were better for the accuracy criterion, with a mean rating of 4.2 and 80% of the questions received a positive rating. The responses scored less for the completeness criterion, with a mean rating of 3.8 and 46.7% of questions received a positive rating. For safety, the mean rating was 3.9 and 53.3% of questions received a positive rating. There was no response with an average negative rating below three. CONCLUSION This study demonstrates promising results regarding potential use of ChatGPT's in providing accurate responses to obstetric clinical questions posed by pregnant women. However, it is crucial to exercise caution when addressing inquiries concerning the safety of the fetus or the mother.

Abstract
BACKGROUND Assessing the umbilical artery pulsatility index via Doppler measurements plays a crucial role in evaluating fetal growth impairment. OBJECTIVE This study aimed to investigate perinatal outcomes associated with discordant pulsatility indices of umbilical arteries in fetuses with growth restriction. STUDY DESIGN In this retrospective cohort study, all singleton pregnancies were included if their estimated fetal weight and/or abdominal circumference fell below the 10th percentile for gestational age (2017-2022). Eligible cases included singleton pregnancies with concurrent sampling of both umbilical arteries within 14 days of birth at the ultrasound evaluation closest to delivery. The exclusion criteria included births before 22 weeks of gestation, evidence of absent or reverse end-diastolic flow in either umbilical artery, and known fetal genetic or structural anomalies. The study compared cases with discordant umbilical artery pulsatility index values (defined as 1 umbilical artery pulsatility index at ≤95th percentile and the other umbilical artery pulsatility index at >95th percentile for gestational age) to pregnancies where both umbilical artery pulsatility indices had normal pulsatility index values and those with both umbilical arteries displaying abnormal pulsatility index values. The primary outcome assessed was the occurrence of composite adverse neonatal outcomes. Multivariable logistic regressions were performed, adjusting for relevant covariates. RESULTS The study encompassed 1014 patients, including 194 patients (19.1%) with discordant umbilical artery pulsatility index values among those who had both umbilical arteries sampled close to delivery, 671 patients (66.2%) with both umbilical arteries having normal pulsatility index values, and 149 patients (14.7%) with both umbilical arteries exhibiting abnormal values. Pregnancies with discordant umbilical artery pulsatility index values displayed compromised sonographic parameters compared with those with both umbilical arteries showing normal pulsatility index values. Similarly, the number of abnormal umbilical artery pulsatility index values was associated with adverse perinatal outcomes in a dose-response manner. Cases with 1 abnormal (discordant) umbilical artery pulsatility index value showed favorable sonographic parameters and perinatal outcomes compared with cases with both abnormal umbilical artery pulsatility index values, and cases with both abnormal umbilical artery pulsatility index values showed worse sonographic parameters and perinatal outcomes compared with cases with discordant UA PI values. Multivariate analysis revealed that discordant umbilical artery pulsatility indices were significantly and independently associated with composite adverse perinatal outcomes, with an adjusted odds ratio of 1.75 (95% confidence interval, 1.24-2.47; P = .002). CONCLUSION Evaluating the resistance indices of both umbilical arteries may provide useful data and assist in assessing adverse perinatal outcomes among fetuses with growth restriction.

Abstract
Genome-wide association studies (GWAS) are one of the best ways to look into the connection between single-nucleotide polymorphisms (SNPs) and the phenotypic performance. This study aimed to identify the genetic variants that significantly affect the important reproduction traits in Vrindavani cattle using genome-wide SNP chip array data. In this study, 96 randomly chosen Vrindavani cows were genotyped using the Illumina Bovine50K BeadChip platform. A linear regression model of the genome-wide association study was fitted in the PLINK program between genome-wide SNP markers and reproduction traits, including age at first calving (AFC), inter-calving period (ICP), dry days (DD), and service period (SP) across the first three lactations. Information on different QTLs and genes, overlapping or adjacent to genomic coordinates of significant SNPs, was also mined from relevant databases in order to identify the biological pathways associated with reproductive traits in bovine. The Bonferroni correction resulted in total 39 SNP markers present on different chromosomes being identified that significantly affected the variation in AFC (6 SNPs), ICP (7 SNPs), DD (9 SNPs), and SP (17 SNPs). Novel potential candidate genes associated with reproductive traits that were identified using the GWAS methodology included UMPS, ITGB5, ADAM2, UPK1B, TEX55, bta-mir-708, TMPO, TDRD5, MAPRE2, PTER, AP3B1, DPP8, PLAT, TXN2, NDUFAF1, TGFA, DTNA, RSU1, KCNQ1, ADAM32, and CHST8. The significant SNPs and genes associated with the reproductive traits and the enriched genes may be exploited as candidate biomarkers in animal improvement programs, especially for improved reproduction performance in bovines.

Abstract
Esophageal adenocarcinoma (EAC) occurs following a series of histological changes through epithelial-mesenchymal transition (EMT). A variable expression of normal and aberrant genes in the tissue can contribute to the development of EAC through the activation or inhibition of critical molecular signaling pathways. Gene expression is regulated by various regulatory factors, including transcription factors and microRNAs (miRs). The exact profile of miRs associated with the pathogenesis of EAC is largely unknown, though some candidate miRNAs have been reported in the literature. To identify the unique miR profile associated with EAC, we compared normal esophageal tissue to EAC tissue using bulk RNA sequencing. RNA sequence data was verified using qPCR of 18 selected genes. Fourteen were confirmed as being upregulated, which include CDH11, PCOLCE, SULF1, GJA4, LUM, CDH6, GNA12, F2RL2, CTSZ, TYROBP, and KDELR3 as well as the downregulation of UGT1A1. We then conducted Ingenuity Pathway Analysis (IPA) to analyze for novel miR-gene relationships through Causal Network Analysis and Upstream Regulator Analysis. We identified 46 miRs that were aberrantly expressed in EAC compared to control tissues. In EAC tissues, seven miRs were associated with activated networks, while 39 miRs were associated with inhibited networks. The miR-gene relationships identified provide novel insights into potentially oncogenic molecular pathways and genes associated with carcinogenesis in esophageal tissue. Our results revealed a distinct miR profile associated with dysregulated genes. The miRs and genes identified in this study may be used in the future as biomarkers and serve as potential therapeutic targets in EAC.

Abstract
We present here two accessible ways for enhanced understanding of complex biological structures and their function in undergraduate Biology and Biochemistry classrooms. These methods can be applied for in-class instruction as well as for remote lessons, as they are cheap, easily available and easy to implement. LEGO® bricks and MERGE CUBE based augmented reality can be applied to make three-dimensional representation for any structure available on PDB. We envisage these techniques to be useful for students when visualizing simple stereochemical problems or complex pathway interactions.

Abstract
BACKGROUND AND OBJECTIVES Close monitoring of patients in the first 2 hours after cesarean delivery (CD) is crucial. Delays in shifting of the post-CD patients led to a chaotic environment in the postoperative ward, suboptimal monitoring, and inadequate nursing care. Our aim was to increase the percentage of post-CD patients shifted from transfer trolley to bed within 10 minutes of arrival in the postoperative ward from a baseline of 64% to 100%, and to maintain that rate for more than 3 weeks. METHODS A quality improvement team including physicians, nurses, and workers was constituted. Problem analysis revealed lack of communication among the caregivers as the main cause of delay. The percentage of post-CD patients shifted from trolley to bed within 10 minutes of being wheeled into the postoperative ward out of the total number of post-CD patients transferred from the operation theater to the postoperative ward was taken as the outcome indicator for the project. Multiple Plan-Do-Study-Act cycles based on the Point of Care Quality Improvement methodology were undertaken to achieve the target. Main interventions were: 1) written information of patient being transferred to operation theater for CD sent to the postoperative ward; 2) stationing of a duty doctor in the postoperative ward; and 3) keeping a buffer of 1 vacant bed in the postoperative ward. The data were plotted weekly as a dynamic time series chart and signals of change were observed. RESULTS Eighty-three percent (172 out of 206) of women were shifted in time by 3 weeks. After Plan-Do-Study-Act 4, the percentages kept improving leading to a median shift from 85.6% to 100% after 10 weeks post-initiation of the project. Sustainment was confirmed by continuing observations for 6 more weeks to ensure that the changed protocol was assimilated in the system. We found that all women were shifted within 10 minutes of their arrival in postoperative ward from trolley to bed. CONCLUSION Providing high-quality care to patients must be a priority for all health care providers. High-quality care is timely, efficient, evidence based, and patient-centric. Delays in transfer of postoperative patients to the monitoring area can be detrimental. The point of Care Quality Improvement methodology is useful and effective in solving complex problems by understanding and fixing the various contributory factors one by one. Reorganization of processes and available manpower without any extra investment in terms of infrastructure and resources is pivotal for long term success of a quality improvement project.

Abstract
An important part of scientific training in undergraduate curriculum involves teaching students how to effectively communicate in science. Scientific writing and oral presentations are important parts of most science classes. The same cannot be said about a new and emerging aspect of many recent scientific articles: graphical abstracts. In recent years, many scientific journals have adopted graphical abstracts as a way to capture both the scientific audience and increase visibility on social media platforms. Graphical abstracts are becoming the norm for many journals; however, there is no equivalent training in undergraduate classes that teaches students the intricate skills of efficient graphical design. In this paper, we share our course design and discuss how students can be taught to design better experiments and excel in communicating their research findings through graphical abstracts.

Abstract
OBJECTIVE To evaluate the role of mid-trimester placental growth factor (PlGF) in patients with abnormal circulating levels of first-trimester biomarkers. METHODS Retrospective cohort study including singleton pregnancies complicated by abnormal first-trimester biomarkers (2017-2020). Pregnancies complicated with chromosomal/structural anomalies were excluded. All patients had ultrasound imaging including uterine artery Doppler combined with measurement of maternal circulating PlGF. Sonographic findings, maternal and perinatal outcomes, and placental histopathology were compared between pregnancies with normal and low (<10th percentile for gestational age) PlGF levels. The diagnostic accuracy of PlGF for the prediction of specific placental-mediated complications was compared with the uterine artery Doppler assessment and additional sonographic findings. RESULTS Seventy-one pregnancies were assessed, of which 35 (49.3%) had low PlGF levels. Maternal sociodemographic characteristics, nulliparity, and aspirin consumption were comparable. In comparison with patients with normal PlGF levels, individuals with low PlGF levels had a higher rate of fetal growth restriction (EFW <3rd centile; 42.9% vs. 8.3%, p = 0.001), preterm-preeclampsia (22.9% vs. 0%, p = 0.002), preterm delivery <34 weeks (54.3% vs. 8.3%, p < 0.001) and maternal vascular malperfusion placental pathology (72.7% vs. 21.7%, p < 0.001) following delivery. Adjusting for uterine artery Doppler and fetal biometry status, mid-trimester low PlGF remained significantly associated with these placental-mediated complications. The predictive capacity of PlGF outperformed ultrasound imaging with only minimal diagnostic improvement when ultrasound information was combined with PlGF status. CONCLUSION In pregnancies with unexplained abnormal first-trimester biomarkers, mid-trimester PlGF outperformed a comprehensive ultrasound assessment in the identification of a subset of patients destined to develop placental dysfunction. This blood test may be an alternative initial approach in this context, especially where access to specialist care is more geographically challenging.

Abstract
Background: Intravesical Bacillus Calmette–Guérin (BCG) instillation is an established form of immunotherapy for intermediate and high-risk bladder cancers. Mandatory cystoscopic surveillance is commonly performed under general anaesthesia (GA) to facilitate biopsy or other procedures. However, it is resource-intensive with unclear clinical benefit. Methods and patients: We performed a two-cycle audit, before and after changing post-BCG surveillance policy, from GA cystoscopy to local anaesthetic flexible cystoscopy (LAFC) on trans urethral laser ablation (TULA) lists, where patients may undergo a tumour biopsy or laser ablation. In the first cycle, we audited 53 patients undergoing 114 post-BCG rigid cystoscopies from January 2018 to December 2019. In the second cycle, there were 56 patients undergoing 99 post-BCG LAFCs on TULA lists in 2020. Results: In the first audit cycle cohort, the mean patient age was 72.29 ± 8.98 years and 48 were men; malignant histology was identified only on five occasions (three grade progressions). Fourteen patients required overnight admission. In the second audit cycle cohort, the mean patient age was 70.44 ± 9.17 years and 47 were men. Four had a grade progression, while another a stage progression. Out of 99 LAFCs, 47 confirmed normal bladder appearance. A biopsy was taken during other 52 cystoscopies: 17 (33%) confirmed malignancy. Fifteen patients showed findings that were labelled as recurrence, but only two required a further GA procedure to deal with recurrence. One patient was admitted for post-procedure bleeding, which settled with irrigation. Conclusion: Local anaesthetic TULA procedure is a safe and effective alternative for a GA rigid cystoscopy to survey bladders of patients on intravesical BCG therapy. Level of evidence: 3

Abstract
OBJECTIVE The optimal timing of an elective cesarean delivery for uncomplicated placenta previa remains controversial. Although the present guidelines recommend an elective cesarean delivery between 360/7 and 376/7 weeks of gestation, data supporting this recommendation does not differentiate in outcomes between elective and emergent delivery, or between women with and without ante-partum hemorrhage. Recommendations regarding optimal timing of delivery are based on the risks and benefits associated with delivery at a certain gestational week, compared with a reference of 38 weeks. Therefore, the aim of this paper was to assess the maternal and neonatal adverse outcomes associated with elective delivery at different gestational weeks from 360/7 to 386/7 weeks compared with expectant management in women with uncomplicated placenta previa. METHODS A retrospective cohort study in a single tertiary medical center of 251 women with a diagnosis of uncomplicated placenta previa, who delivered between 360/7 and 386/7 weeks of gestation, who delivered at our center between Jan 2011 and Dec 2019. Maternal and neonatal outcomes at each gestational week were compared with expectant management. RESULTS At 360/7-366/7 weeks, the rate of composite maternal adverse outcome was similar for elective delivery and expectant management (10.5% vs 7.7%, p = .68). Similarly, at 370/7-376/7 the rate of composite maternal adverse outcome was comparable for elective cesarean delivery and expectant management (7.2% vs 6.4%, p = .54). Maternal bleeding was the main indication of an urgent cesarean delivery, and account for 86% of urgent cesarean delivery at 360/7-366/7, 76.4% of urgent cesarean delivery at 370/7-376/7, and for 70.6% of all urgent cesarean delivery at 380/7-386/7 weeks. This group of women who were delivered due to maternal bleeding had a history of maternal bleeding during 2nd and/or 3rd trimester in 75-92.3% of cases. Composite adverse neonatal outcome was similar for elective cesarean delivery at each gestational age compared with expectant management. The risk for lower 5-min APGAR score and hypoglycemia was higher for newborns that were delivered electively a 36th weeks of gestation compared with expectant management. CONCLUSION Our study suggests that the optimal time of delivery for women with an uncomplicated placenta previa is between 380/7 and 386/7 weeks of gestation, especially in women without ante-partum bleeding.

Hemodynamic functional connectivity optimization of frequency EEG microstates enables attention LSTM framework to classify distinct temporal cortical communications of different cognitive tasks. Brain Inform 2022; 9:25.

Abstract
Temporal analysis of global cortical communication of cognitive tasks in coarse EEG information is still challenging due to the underlying complex neural mechanisms. This study proposes an attention-based time-series deep learning framework that processes fMRI functional connectivity optimized quasi-stable frequency microstates for classifying distinct temporal cortical communications of the cognitive task. Seventy volunteers were subjected to visual target detection tasks, and their electroencephalogram (EEG) and functional MRI (fMRI) were acquired simultaneously. At first, the acquired EEG information was preprocessed and bandpass to delta, theta, alpha, beta, and gamma bands and then subjected to quasi-stable frequency-microstate estimation. Subsequently, time-series elicitation of each frequency microstates is optimized with graph theory measures of simultaneously eliciting fMRI functional connectivity between frontal, parietal, and temporal cortices. The distinct neural mechanisms associated with each optimized frequency-microstate were analyzed using microstate-informed fMRI. Finally, these optimized, quasi-stable frequency microstates were employed to train and validate the attention-based Long Short-Term Memory (LSTM) time-series architecture for classifying distinct temporal cortical communications of the target from other cognitive tasks. The temporal, sliding input sampling windows were chosen between 180 to 750 ms/segment based on the stability of transition probabilities of the optimized microstates. The results revealed 12 distinct frequency microstates capable of deciphering target detections' temporal cortical communications from other task engagements. Particularly, fMRI functional connectivity measures of target engagement were observed significantly correlated with the right-diagonal delta (r = 0.31), anterior-posterior theta (r = 0.35), left-right theta (r = - 0.32), alpha (r = - 0.31) microstates. Further, neuro-vascular information of microstate-informed fMRI analysis revealed the association of delta/theta and alpha/beta microstates with cortical communications and local neural processing, respectively. The classification accuracies of the attention-based LSTM were higher than the traditional LSTM architectures, particularly the frameworks that sampled the EEG data with a temporal width of 300 ms/segment. In conclusion, the study demonstrates reliable temporal classifications of global cortical communication of distinct tasks using an attention-based LSTM utilizing fMRI functional connectivity optimized quasi-stable frequency microstates.

Abstract
Background Periodontitis is the common oral condition which affects the periodontium of the teeth that leads to destruction of periodontal ligaments and alveolar bone. Open flap debridement is the surgical procedure which provides access and visibility of the site, application of laser as an adjunct has various advantanges. Objective To compare clinical outcomes after open flap debridement with or without diode laser. Method Patients aged 25-45 years diagnosed with infrabony defect ≥ 5 mm visiting Department of Dental Surgery, Bir Hospital. Control group sites were treated with open flap debridement alone, whereas test-groups were treated with Open flap debridement with diode laser. Various parameters like Plaque index, Gingival index, Pocket depth and Clinical attachment level were assessed and compared between groups at baseline, 3 and 6 months. Result The mean plaque and gingival scores improved in both the control and test groups at 3 and 6 months follow up as compared to baseline and was statistically nonsignificant between two groups. Open flap debridement with or without diode laser in the treatment of periodontal intrabony defects did not produce significant reduction in pocket depth and gain in clinical attachment level. Conclusion There was no significant differences in the clinical parameters were seen in the surgical flap debridement of infrabony pocket with and without diode laser. Diode laser can be used safely as an adjunct. However, long-term, multicentric, histologic and microbial studies are required.

Abstract
Neonatal ruminants are born without any humoral immunity due to lack of placental transfer of immunoglobulins during gestation. This predisposes the newborn buffalo calves to a high incidence of morbidity and mortality on exposure to infectious agents. Colostrum is the first milk produced by the females after calving and is a rich source of immunoglobulins, especially immunoglobulin G (IgG). The immunocompetence of the neonates can be boosted by feeding them sufficient amount of good quality colostrum within a few hours after birth. Optimal colostrum management at a farm not only reduces the occurrence of diseases among the younger stock but also enhances their growth performance and productivity once they are adults. In the present study, eighty animals at a Murrah buffalo farm were screened for the concentration of IgG in the colostrum collected from recently parturated females and in the serum collected from their calves within 6 to 12 h of colostrum consumption to determine the status of transfer of passive immunity. Indirect ELISA was used to estimate the IgG levels. The overall mean (range) of colostral and serum IgG concentration was found to be 50.44±3.36 (12.71 to 227.78) and 10.85±0.62 (0.25 to 19.88) mg/ml, respectively for all the 80 animals. Routine screening of buffaloes, in a similar way, will help to reduce calf deaths due to immunodeficiency.

Abstract
Background Hirsutism is excess terminal hair growth in women at androgen-dependent sites of the body and it has great impact on psychological and social aspects of their lives, thus affecting their quality of life (QoL). Several studies assessing the quality of life in hirsute women could be found in world literature but none in Nepalese literature. So, this study was undertaken for the assessment of the impact of hirsutism on the quality of life in Nepalese women. Objective To assess the effect of hirsutism on quality of life of women in a tertiary center of Eastern Nepal and its association with various socio-demographic and clinical parameters. Method A cross-sectional questionnaire-based study was conducted in 49 participants aged 10 to 49 years at the Department of Dermatology, B.P. Koirala Institute of Health Sciences. Clinically diagnosed hirsute females with modified Ferriman-Gallwey (mFG) score > 8, were enrolled and asked to fill Dermatology Life Quality Index (DLQI) questionnaire in the Nepalese version. Result More than 57.2% of the study population was of age 20 to 29 years with a mean of 27.76±8.08 years. The mean Dermatology Life Quality Index score was 7.78±4.95. The moderate effect was seen in the majority of participants (36.7%) with a predominant effect upon aspects of life like daily activities and symptoms and feelings. Participants with higher mF-G score (22.15±3.82) had a very large effect on their quality of life. Younger unmarried women with a school education and having a longer duration of hirsutism were found to have a higher effect upon their quality of life. However, the association was not statistically significant. Conclusion Hirsutism had affected the quality of life moderately with predominant effect upon aspects like daily activities and symptoms and feelings. No significant association was elicited between severity of hirsutism and its effect on quality of life from our study.

Abstract
The present study performs landcover modelling using the SLEUTH model. The urban land use changing factors are calibrated to predict the Land Use Land Cover (LULC) for a densely populated and developing smart city, Prayagraj, India. This research aims to use the SLEUTH model for simulating the future urban growth with the help of historical LULC (1990-2020), road network and elevation data. The influence of road gravity and slope resistant coefficients is very significant in this study's outcome. The built-up area of the region increased from 40.22 km2 (5.10% of total area) in 1990 to 85.89 km2 (10.89%) in 2020. According to prediction results, in the next 20 years, the built-up growth rate would be 1.9% and approximated built-up area would be 118.66 km2 (14.98%) in the year 2040. The quality of the result has been quantified in terms of best fit value of Optimal SLEUTH Metric (OSM) and validated against the existing LULC. The study utilises a spatially explicit urban growth model with 30 m resolution remote sensing data and provides future landuse of Prayagraj city.

Correlation of fetal ventricular size and need for postnatal cerebrospinal fluid diversion surgery in open spina bifida. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2022; 59:799-803.

Abstract
OBJECTIVES Open spina bifida is a common cause of hydrocephalus in the postnatal period. In-utero closure of the fetal spinal defect decreases the need for postnatal cerebrospinal fluid (CSF) diversion surgery. Good prenatal predictors of the need for postnatal CSF diversion surgery are currently lacking. In this study, we aimed to assess the association of fetal ventriculomegaly and its progression over the course of pregnancy with the rate of postnatal hydrocephalus requiring intervention. METHODS In this retrospective study, fetuses with a prenatal diagnosis of open spina bifida were assessed longitudinally. Ventricular diameter, as well as other potential predictors of the need for postnatal CSF diversion surgery, were compared between fetuses undergoing prenatal closure and those undergoing postnatal repair. RESULTS The diameter of the lateral ventricle increased significantly throughout gestation in both groups, but there was no difference in maximum ventricular diameter at first or last assessment between fetuses undergoing prenatal closure and those undergoing postnatal repair. There was no significant difference in the rate of progression of ventriculomegaly between the two groups, with a mean progression rate of 0.83 ± 0.5 mm/week in the prenatal-repair group and 0.6 ± 0.6 mm/week in the postnatal-repair group (P = 0.098). Fetal repair of open spina bifida was associated with a lower rate of postnatal CSF diversion surgery (P < 0.001). In all subjects, regardless of whether they had prenatal or postnatal surgery, the severity of ventriculomegaly at first and last assessments was associated independently with the need for postnatal CSF diversion surgery (P = 0.005 and P = 0.001, respectively), with a greater need for surgery in fetuses with larger ventricular size, even after controlling for gestational age at assessment. CONCLUSIONS In fetuses with open spina bifida, fetal ventricular size increases regardless of whether spina bifida closure is performed prenatally or postnatally, but the need for CSF diversion surgery is significantly lower in those undergoing prenatal repair. Ventriculomegaly is associated independently with the need for postnatal CSF diversion in fetuses with open spina bifida, irrespective of timing of closure. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
BACKGROUND Genital tuberculosis (TB) continues to remain an important cause of infertility in women, especially in developing countries. It is mostly consequent to a primary infection elsewhere in the body. The diagnosis is challenging, considering its paucibacillary nature. Although there are many studies on association of genital tuberculosis with infertility, there is paucity of literature on impact of extragenital tuberculosis on fertility of women through involvement of female reproductive organs. The various diagnostic modalities available have limitations and quest is ongoing for the best diagnostic test. METHOD This was a prospective observational study conducted at the infertility clinic of a tertiary care health facility where 60 infertile women with either tubal factor or unexplained infertility with or without past history of extragenital tuberculosis were enrolled as study subjects or controls respectively. Mantoux test was performed in all women and diagnostic laparo-hysteroscopy was performed in all women to look for any evidence of uterine and/or tubal damage. The peritoneal fluid was sent for GeneXpert and Liquid culture for mycobacterium tuberculosis. Results of Mantoux test, GeneXpert and liquid culture were compared with the laparohysteroscopic findings. RESULT Of the thirty infertile women in the study group, 27/30 (90%) had a history of pulmonary tuberculosis and 3/30 (10%) had history of tubercular cervical lymphadenopathy. It was observed that Mantoux test was positive (induration >10 mm) in 27/30 (90%) of women in the study group as compared to only 4/30 (13.3%) controls. Abnormal hysteroscopic findings were documented in 26.6% (8/30) study group women as compared to 6.6% (2/30) women in the control group. Similarly, 60% (18/30) of women in the study group had abnormal laparoscopic findings compared to 33% (10/30) in the control group. Seven out of thirty (23.3%) women were positive for GeneXpert in the study group compared to only 1/30 (3.3%) in the control group. Similarly, liquid culture was positive in 6/30 (20%) of women in the study group as compared to 1/30 (3.3%) in the control group. All the above differences were statistically significant. We observed that the sensitivity of Mantoux test (75.8%) stand alone was higher than the other tests combined (50%). However, specificity and positive predictive value (PPV) increases markedly (up to 100%) to when all the three tests are combined. CONCLUSION The authors conclude that all women presenting with infertility should be screened for a past history of tuberculosis and actively worked up for genital tuberculosis in case the history is positive. The various available tests (Mantoux test, GeneXpert and liquid culture) have their limitations for the diagnosis of genital tuberculosis. Thus an approach of early resort to laparohysteroscopy in suspected patients is desirable so that definitive management may be instituted timely and promptly.

Abstract
PURPOSE To describe the postnatal outcome of fetal meconium peritonitis and identify prenatal predictors of neonatal surgery. METHODS We retrospectively reviewed all fetuses with ultrasound findings suspicious for meconium peritonitis at a single center over a 10-year period. A systematic review and meta-analysis were then performed pooling our results with previous studies assessing prenatally diagnosed meconium peritonitis and postnatal outcome. Prenatal sonographic findings were analyzed to identify predictors for postnatal surgery. RESULTS 34 cases suggestive of meconium peritonitis were diagnosed at our center. These were pooled with cases from 14 other studies yielding a total of 244 cases. Postnatal abdominal surgery was required in two thirds of case (66.5 %). The strongest predictor of neonatal surgery was meconium pseudocyst (OR [95 % CI] 6.75 [2.53-18.01]), followed by bowel dilation (OR [95 % CI] 4.17 [1.93-9.05]) and ascites (OR [95 % CI] 2.57 [1.07-5.24]). The most common cause of intestinal perforation and meconium peritonitis, found in 52.2 % of the cases, was small bowel atresia. Cystic fibrosis was diagnosed in 9.8 % of cases. Short-term neonatal outcomes were favorable, with a post-operative mortality rate of 8.1 % and a survival rate of 100 % in neonates not requiring surgery. CONCLUSION Meconium pseudocysts, bowel dilation, and ascites are prenatal predictors of neonatal surgery in cases of meconium peritonitis. Fetuses with these findings should be delivered in centers with pediatric surgery services. Though the prognosis is favorable, cystic fibrosis complicates postnatal outcomes.

Abstract
BACKGROUND Patients at high risk of severe preeclampsia and fetal growth restriction have low circulating levels of placental growth factor and features of maternal vascular malperfusion placental pathology at delivery. Multimodal screening and commencement of aspirin prophylaxis at 11 to 13 weeks' gestation markedly reduces the risk of preterm delivery with preeclampsia. However, the additional role of low-molecular-weight heparin and mechanisms of action remain uncertain. Because low-molecular-weight heparin augments the production and release of placental growth factor in vitro by both placental villi and vascular endothelium, it may be effective to suppress the risk of severe preeclampsia in a niche group of high-risk patients with low circulating placental growth factor in the early second trimester. OBJECTIVE This study aimed to define a gestational age-specific reference range for placental growth factor and to test the hypothesis that prophylactic low-molecular-weight heparin administered in the early second trimester may restore deficient circulating placental growth factor levels and thereby prolong pregnancy. STUDY DESIGN Centile curves for circulating placental growth factor levels from 12 to 36 weeks' gestation were derived using quantile regression of combined data from a published cohort of 4207 unselected nulliparous patients in Cambridge, United Kingdom, at 4 sampling time points (12, 20, 28, and 36 weeks' gestation) and the White majority (n=531) of a healthy nulliparous cohort in Toronto, Canada, at 16 weeks' gestation using the same test platform. Within a specialty high-risk clinic in Toronto, a niche group of 7 patients with a circulating placental growth factor at the <10th centile in the early second trimester received daily prophylactic low-molecular-weight heparin (enoxaparin; 40 mg subcutaneously) and were followed up until delivery (group 1). Their baseline characteristics, delivery details, and placental pathologies were compared with 5 similar patients who did not receive low-molecular-weight heparin during the observation period (group 2) and further with 21 patients who delivered with severe preeclampsia (group 3) in the same institution. RESULTS A gestational age-specific reference range for placental growth factor levels at weekly intervals between 12 and 36 weeks was established for White women with singleton pregnancies. Within group 1, 5 of 7 patients demonstrated a sustained increase in circulating placental growth factor levels, whereas placental growth factor levels did not increase in group 2 or group 3 patients who did not receive low-molecular-weight heparin. Group 1 patients receiving low-molecular-weight heparin therapy exhibited a later gestation at delivery, relative to groups 2 and 3 (36 weeks [33-37] vs 23 weeks [22-26] and 28 weeks [27-31], respectively), and consequently had higher birthweights (1.93 kg [1.1-2.7] vs 0.32 kg [0.19-0.39] and 0.73 kg [0.52-1.03], respectively). The incidence of stillbirth was lowest in group 1 (14% [1 of 7]), relative to groups 2 and 3 (80% [4 of 5] and 29% [6 of 21], respectively). Maternal vascular malperfusion was the most common placental pathology found in association with abnormal uterine artery Doppler. CONCLUSION In patients at high risk of a serious adverse pregnancy outcome owing to placental disease, the addition of low-molecular-weight heparin to aspirin prophylaxis in the early second trimester may restore deficient circulating placental growth factor to mediate an improved perinatal outcome. These data support the implementation of a multicenter pilot randomized control trial where patients are recruited primarily based on the assessment of placental function in the early second trimester.

Abstract
Introduction: Pre-operative identification of patients with inadequate hamstring graft for anterior cruciate ligament reconstruction is still a subject of interest. The purpose of this study is to correlate dimension of a harvested dimensions graft with patient physical anthropometric variables. Materials and methods: This cohort study included 280 patients (male = 226, female = 54) scheduled for primary anterior cruciate ligament (ACL) reconstruction. Interrelationships between quadruple semitendinosus (ST) graft and anthropometric parameters (age, sex, height, weight, and BMI) were assessed using Pearson Correlation test and regression analysis. Difference among gender was analysed using Mann Whitney and t test. The observed graft diameter was also compared with the literature using Bland – Altman plot. Results: Mean age of cohort was 29 years (range, 17-50 years), mean height was 1.69m (range, 1.6-1.9m), mean weight was 75 kg (range, 50-116kg) and mean BMI was 26kg/m2 (range 16.65-40.40kg/m2). Mean quadruple length of harvested ST graft was 7cm (7.1±0.6 cm, range, 5.6-8.8cm) and mean diameter was 8mm (8.2±0.8mm, range, 6.5-10mm). Only height and weight were significantly correlated with graft length and diameter in both sex (p value <0.05). Female, compared to male, had significantly smaller (p<0.0001) and thinner graft (p<0.0001). There was a strong agreement between the literature and our observed graft diameter, but with an overestimated graft diameter in 18.5% of the cases. Conclusion: Among anthropometric parameter, only height and weight had moderate positive correlation with graft diameter. Males had longer and wider ST graft in contrast to age-matched female group.
