Correlation of non-stress test with fetal outcome in term of Apgar score- a prospective observation study

Background: Non-stress test (NST) is a graphical recording of changes in fetal heart activity and uterine contraction along with fetal movement when uterus is quiescent. The objectives of antepartum fetal surveillance are to prevent fetal death and avoidance of unnecessary intervention. This study using NST as a tool for routine antepartum fetal surveillance was trying to catch up those fetuses who might be at risk in womb and provide prompt intervention in otherwise considered normal pregnancies without any obvious high risk factor thus giving the best outcome in mothers.Methods: The objective of this study was to evaluate the correlation of the non-stress test with fetal outcome in pregnancies from 37-42 weeks of gestation.  This was a prospective observational study at Pannadhaya Rajkiya Mahila Chikitsalya Udaipur (Rajasthan) from February 2022 to July 2022. This study included 100 normal pregnant mothers from 37 weeks to 42 weeks who were subjected to NST.Results: The parameters of poor fetal outcome like Apgar score <7 at 5 minutes had increased incidences in the non reactive group.Conclusions: NST tells about acute fetal hypoxia and decision to delivery time can be made for those patients with fetal distress so that a major improvement in the outcome among parturient can be achieved with abnormal NST results. So This study suggested that the NST was found to be a good predictor of the healthy foetus even in normal pregnancies between 37-42 weeks of gestation and the probability of an adverse outcome such as poor Apgar score increases with a non reactive strip

A rare case of genital myiasis in genital prolapse

Genital myiasis is an infestation by fly larvae in genital organs, where they feed and develop as parasites. They can cause severe infection, inflammatory reaction and can be linked to psychiatric disturbances. Commonly cutaneous, ophthalmic, auricular and nasopharyngeal myiasis are seen, with genital myiasis being a rare condition. We reported a case of an 82-year-old postmenopausal female who presented with the complaint of intense pain in genital region. After clinical evaluation she was clinically diagnosed as a case of genital myiasis of prolapsed uterus. Myiasis of the genital organ is a rare clinical entity. Good personal hygiene and proper sanitary conditions are very crucial for prevention of myiasis

A rare case of giant condyloma acuminata during pregnancy

Genital warts (Condyloma acuminata) are a benign lesion caused by human papillomavirus (HPV) type-6 or type-11 and are usually transmitted sexually. During pregnancy, condyloma has a tendency to proliferate and may have recurrence. We have a case of G2P1L1 38 weeks previously normal vaginal delivered patient in our hospital with extensive genital warts. Patient was successfully managed by surgical excision and after that in follow up after 2 months for podophyllin resin application on remaining lesions. HPV infection presentation can range from asymptomatic to cervical cancer. Small genital wart lesion may become extensive and cumbersome during pregnancy and again regress after delivery in due course of time. HPV vaccination, sex education and early treatment of condyloma lesions should prevent and, in any case, improve the prognosis of this disease

Ultrasound assessment of foetal head-perineum distance prior to induction of labour as a predictor of successful vaginal delivery: a prospective study from a tertiary care hospital of Rajasthan

Background: Induction of labor (IOL) is one of the most frequent obstetric procedures require for various obstetrics indications in 13-20% of term. Traditionally success of induction has been determined by Bishop score, but this score is observer based and significant inter observer disagreements have been noted. Ultrasound can help obstetricians in counselling patients before induction of labour and explain the probability of successful induction. So in this study we did ultrasound assessment of foetal head-perineum distance prior to induction of labour as a predictor of successful vaginal delivery. Methods: All eligible women who are planned for induction of labour will undergo ultrasound assessment of foetal head–perineum distance prior to induction of labour. Transvaginal ultrasound will also be performed using ultrasound probe to measure cervical length. After the scans, prevaginal examination will be performed to assess the various components of modified Bishop score (min 0, max 10). If cervix is found unfavourable, induction of labour will be done. If patient did not go into active labour, then induction will be considered unsuccessful) or else oxytocin drip in cases where cervix is found favourable. The patients will be followed up till delivery. Results: Out of 125 patients enrolled for the study, 101 women delivered successfully vaginally and 24 had to undergo caesarean delivery. Of these 24 cases of caesarean delivery, 11 cases were excluded as the operative procedure was performed for indication not related to unsuccessful induction such as occurrence of foetal distress in labour, thick meconium-stained liquor with unfavourable cervix. The final analysis was performed from 114 subjects (101 vaginal births and 13 caesarean births). Conclusions: Transperineal fetal head–perineum distance is less painful as less time consuming and less acceptable by patients compare to Transvaginal measurement of cervical length and painful digital examination for bishop score

Activity in deep intermediate layer collicular neurons during interrupted saccades

Abstract The activity of neurons located in the deep intermediate and adjacent deep layers (hereafter called just deep intermediate layer neurons) of the superior colliculus (SC) in monkeys was recorded during saccades interrupted by electrical stimulation of the brainstem omnipause neuron (OPN) region. The goal of the experiment was to determine if these neurons maintained their discharge during the saccadic interruption, and, thus, could potentially provide a memory trace for the intended movement which ends accurately on target in spite of the perturbation. The collicular neurons recorded in the present study were located in the rostral three-fifths of the colliculus. Most of these cells tended to show considerable presaccadic activity during a delayed saccade paradigm, and, therefore, probably overlap with the population of SC cells called buildup neurons or prelude bursters in previous studies. The effect of electrical stimulation in the OPN region (which interrupted ongoing saccades) on the discharge of these neurons was measured by computing the percentage reduction in a cell&apos;s activity compared to that present during non-interrupted saccades. During saccade interruption about 70% of deep intermediate layer neurons experienced a major reduction (30% or greater) in their activity, but discharge recovered quickly after the termination of the stimulation as the eyes resumed their movement to finish the saccade on the target. Therefore, the pattern of activity recorded in most of the deep intermediate layer neurons during interrupted saccades qualitatively resembled that previously reported for the saccade-related burst neurons which tend to be located more dorsally in the intermediate layer. In contrast, some of our cells (30%) showed little or no perturbation in their activity caused by the saccade interrupting stimulation. Because all the more dorsally located burst neurons and the majority of our deep intermediate layer neurons show a total or major suppression in their discharge during interrupted saccades, it seems unlikely that the colliculus by itself could maintain an accurate memory of the desired saccadic goal or the remaining dynamic motor error required to account for the accuracy of the resumed movement which occurs following the interruption. However, it remains possible that the smaller proportion of our neurons whose activity was not perturbed during interrupted movements could play a role in the mechanisms underlying saccade accuracy in the interrupted saccade paradigm. Interrupted saccades have longer durations than normal saccades to the same target. Therefore, we investigated whether the discharge of our deeper collicular cells was also necessarily prolonged during interrupted saccades, and, if so, how the prolongation compared to the prolongation of the saccade. Sixty percent of our sample neurons showed a prolongation in discharge that was approximately the same as the prolongation in saccade duration (difference &lt;15 ms in magnitude). The observation that temporal discharge in our neurons was perturbed to roughly match saccadic temporal perturbation suggests that dynamic feedback about ongoing saccadic motion is provided to the colliculus, but does not necessarily imply that this structure is the site responsible for the computation of dynamic motor error

Single cell signals: an oculomotor perspective

Abstract: We examine the activity of individual neurons in three different brain areas where firing rate, number of spikes (the integral of discharge rate), and the location of the active cell within a motor map are used as coding schemes. The correlations between single cell activity and the parameters of a movement range from extremely tight (motoneurons) to non-existent (superior colliculus). We argue that the relationship between the activity of single cell activity and global aspects of behavior are best described as coarse coding for all three types of neuron. We also present evidence, in some cases in a preliminary and suggestive form, that the distribution of spikes in time, rather than average firing rate, may be important for all three neuron types, including those using a place code. Finally, we describe difficulties encountered in obtaining an estimate of the motor command when more than one oculomotor system is active

Subtype-Specific and Co-Occurring Genetic Alterations in B-cell Non-Hodgkin Lymphoma

B-cell non-Hodgkin lymphoma (B-NHL) encompasses multiple clinically and phenotypically distinct subtypes of malignancy with unique molecular etiologies. Common subtypes of B-NHL, such as diffuse large B-cell lymphoma, have been comprehensively interrogated at the genomic level, but rarer subtypes, such as mantle cell lymphoma, remain less extensively characterized. Furthermore, multiple B-NHL subtypes have thus far not been comprehensively compared using the same methodology to identify conserved or subtype-specific patterns of genomic alterations. Here, we employed a large targeted hybrid-capture sequencing approach encompassing 380 genes to interrogate the genomic landscapes of 685 B-NHL tumors at high depth, including diffuse large B-cell lymphoma, mantle cell lymphoma, follicular lymphoma, and Burkitt lymphoma. We identified conserved hallmarks of B-NHL that were deregulated in the majority of tumors from each subtype, including frequent genetic deregulation of the ubiquitin proteasome system. In addition, we identified subtype-specific patterns of genetic alterations, including clusters of co-occurring mutations and DNA copy number alterations. The cumulative burden of mutations within a single cluster were more discriminatory of B-NHL subtypes than individual mutations, implicating likely patterns of genetic cooperation that contribute to disease etiology. We therefore provide the first cross-sectional analysis of mutations and DNA copy number alterations across major B-NHL subtypes and a framework of co-occurring genetic alterations that deregulate genetic hallmarks and likely cooperate in lymphomagenesis

BLOOM: A 176B-Parameter Open-Access Multilingual Language Model

Large language models (LLMs) have been shown to be able to perform new tasks based on a few demonstrations or natural language instructions. While these capabilities have led to widespread adoption, most LLMs are developed by resource-rich organizations and are frequently kept from the public. As a step towards democratizing this powerful technology, we present BLOOM, a 176B-parameter open-access language model designed and built thanks to a collaboration of hundreds of researchers. BLOOM is a decoder-only Transformer language model that was trained on the ROOTS corpus, a dataset comprising hundreds of sources in 46 natural and 13 programming languages (59 in total). We find that BLOOM achieves competitive performance on a wide variety of benchmarks, with stronger results after undergoing multitask prompted finetuning. To facilitate future research and applications using LLMs, we publicly release our models and code under the Responsible AI License

The impact of immediate breast reconstruction on the time to delivery of adjuvant therapy: the iBRA-2 study

Background: Immediate breast reconstruction (IBR) is routinely offered to improve quality-of-life for women requiring mastectomy, but there are concerns that more complex surgery may delay adjuvant oncological treatments and compromise long-term outcomes. High-quality evidence is lacking. The iBRA-2 study aimed to investigate the impact of IBR on time to adjuvant therapy. Methods: Consecutive women undergoing mastectomy ± IBR for breast cancer July–December, 2016 were included. Patient demographics, operative, oncological and complication data were collected. Time from last definitive cancer surgery to first adjuvant treatment for patients undergoing mastectomy ± IBR were compared and risk factors associated with delays explored. Results: A total of 2540 patients were recruited from 76 centres; 1008 (39.7%) underwent IBR (implant-only [n = 675, 26.6%]; pedicled flaps [n = 105,4.1%] and free-flaps [n = 228, 8.9%]). Complications requiring re-admission or re-operation were significantly more common in patients undergoing IBR than those receiving mastectomy. Adjuvant chemotherapy or radiotherapy was required by 1235 (48.6%) patients. No clinically significant differences were seen in time to adjuvant therapy between patient groups but major complications irrespective of surgery received were significantly associated with treatment delays. Conclusions: IBR does not result in clinically significant delays to adjuvant therapy, but post-operative complications are associated with treatment delays. Strategies to minimise complications, including careful patient selection, are required to improve outcomes for patients

AI is a viable alternative to high throughput screening: a 318-target study

: High throughput screening (HTS) is routinely used to identify bioactive small molecules. This requires physical compounds, which limits coverage of accessible chemical space. Computational approaches combined with vast on-demand chemical libraries can access far greater chemical space, provided that the predictive accuracy is sufficient to identify useful molecules. Through the largest and most diverse virtual HTS campaign reported to date, comprising 318 individual projects, we demonstrate that our AtomNet® convolutional neural network successfully finds novel hits across every major therapeutic area and protein class. We address historical limitations of computational screening by demonstrating success for target proteins without known binders, high-quality X-ray crystal structures, or manual cherry-picking of compounds. We show that the molecules selected by the AtomNet® model are novel drug-like scaffolds rather than minor modifications to known bioactive compounds. Our empirical results suggest that computational methods can substantially replace HTS as the first step of small-molecule drug discovery
