Randomized control comparative study to evaluate the effect of camylofin dihydrochloride and valethamate bromide in active phase of first stage of labour
Background: Numerous drugs have been used to shorten the active phase of labor. Do they really shorten the duration of labor? What adverse effects do they have on the baby and the mother? These questions were the basis to perform the present study of comparing two of such drugs, injection Camylofin dihydrochloride and injection Valethamate bromide with control subjects. Aim of the study was to assess the effect of camylofin dihydrochloride and valethamate bromide on active phase of first stage of labour.
Methods: This is an open label randomized controlled study of 120 eligible women with spontaneous onset of labour at SSG hospital, Vadodara, India. Women were randomized to receive either a single intra-muscular Camylofin, 3 doses of intra-venous Valethamate or third as control group. The main outcome measure was duration of active phase of first stage of labour and rate of cervical dilatation. The study was conducted over a period of 9 months from May 2022 to January 2024.
Results: Mean duration of active phase of labour was 4.33±1.32 hours, 6.74±1.26 hours and 6.83±1.65 hours in Camylofin, Valethamate and control group respectively with p value <0.0001. Mean rate of cervical dilatation was 1.47±0.41 cm/hour, 0.91±0.23 cm/hour and 0.87±0.18 cm/hour in three groups respectively. There was no significant difference in maternal side effects and neonatal outcome among them.
Conclusions: Considering the results of this study, it can be concluded Camylofin is superior to Valethamate in decreasing total duration of active phase of first stage with higher cervical dilatation rate
Stimulated Raman Histology for Intraoperative Guidance in the Resection of a Recurrent Atypical Spheno-orbital Meningioma: A Case Report and Review of Literature
Meningiomas are the most common intracranial, extra-axial neoplasms and account for a significant proportion of all central nervous system (CNS) tumors. Regardless of the grade, treatment typically involves upfront surgical resection. However, in many instances, especially in meningiomas arising from the skull base, complete removal is often difficult given the close proximity to important anatomic structures. In this report, we discuss the use of stimulated Raman histology as a means to identify tissue boundaries during the resection of an extensive, recurrent, atypical spheno-orbital meningioma. We report a 75-year-old male with a history of a prior left frontotemporal craniotomy for a grade II meningioma three years prior, who presented with worsening left-sided visual loss and pronounced temporal bossing. Repeat magnetic resonance imaging (MRI) revealed a recurrent left spheno-orbital tumor suggestive of a meningioma extending into the middle cranial fossa, the lateral orbit, and the temporalis muscle. He underwent an extended orbito-pterional craniotomy, and intraoperative stimulated Raman histology aided in the identification of tumor margins within the orbit and the temporalis muscle in order to better preserve the normal orbital contents and muscle bulk of the infratemporal fossa. This case demonstrates the utility of stimulated Raman histology during the resection of invasive skull base tumors. The immediate intraoperative Raman histologic sections can clearly identify tissue boundaries and thus help preserve important anatomic structures. Continued development of this method can potentially improve the accuracy of intraoperative diagnoses and guide surgeons during tumor resections near eloquent anatomical regions or important normal structures
Open Vocabulary Semantic Segmentation with Patch Aligned Contrastive Learning
We introduce Patch Aligned Contrastive Learning (PACL), a modified
compatibility function for CLIP's contrastive loss, intending to train an
alignment between the patch tokens of the vision encoder and the CLS token of
the text encoder. With such an alignment, a model can identify regions of an
image corresponding to a given text input, and therefore transfer seamlessly to
the task of open vocabulary semantic segmentation without requiring any
segmentation annotations during training. Using pre-trained CLIP encoders with
PACL, we are able to set the state-of-the-art on the task of open vocabulary
zero-shot segmentation on 4 different segmentation benchmarks: Pascal VOC,
Pascal Context, COCO Stuff and ADE20K. Furthermore, we show that PACL is also
applicable to image-level predictions and when used with a CLIP backbone,
provides a general improvement in zero-shot classification accuracy compared to
CLIP, across a suite of 12 image classification datasets
Open appendicectomy stump: invaginate or not to invaginate?
Acute appendicitis remains the most common abdominal surgical emergency. Appendicectomy is the standard treatment of acute appendicitis, which performed by open or laparoscopic approach. During open method, after removal of appendix, stump simple ligation or simple ligation and invagination. A prospective randomized study conducted at Smt SCL General Hospital, Smt NHL municipal Medical College, Ahmedabad between October 2009 to September 2011 to evaluate the necessity of appendicular stump invagination during appendicectomy. A total 110 patients were studied and randomized into two group, Group I stump simple ligation, transfixation and invagination and Group II stump simple ligation and transfixation only. There was no statically significant difference in the rate of postoperative complication and post operative hospital stay between the two groups. The mean operating time was significantly shorter in group without invagination. The rate of postoperative paralytic ileus was more in group I. We conclude that simple ligation of the appendicular stump during appendicectomy is safe, simple and shortens operating time
How penalizing substance use in pregnancy affects treatment and research: A qualitative examination of researchers\u27 perspectives
INTRODUCTION: Laws regulating substance use in pregnancy are changing and may have unintended consequences on scientific efforts to address the opioid epidemic. Yet, how these laws affect care and research is poorly understood.
METHODS: We conducted semi-structured qualitative interviews using purposive and snowball sampling of researchers who have engaged pregnant people experiencing substance use. We explored views on laws governing substance use in pregnancy and legal reform possibilities. Interviews were double coded. Data were examined using thematic analysis.
RESULTS: We interviewed 22 researchers (response rate: 71 per cent) and identified four themes: (i) harms of punitive laws, (ii) negative legal impacts on research, (iii) proposals for legal reform, and (iv) activism over time.
DISCUSSION: Researchers view laws penalizing substance use during pregnancy as failing to treat addiction as a disease and harming pregnant people and families. Respondents routinely made scientific compromises to protect participants. While some have successfully advocated for legal reform, ongoing advocacy is needed.
CONCLUSION: Adverse impacts from criminalizing substance use during pregnancy extend to research on this common and stigmatized problem. Rather than penalizing substance use in pregnancy, laws should approach addiction as a medical issue and support scientific efforts to improve outcomes for affected families

Cardiac CT and MRI guide surgery in impending left ventricular rupture after acute myocardial infarction
We report the case of a 67 year-old patient who presented with worsening chest pain and shortness of breath, four days post acute myocardial infarction. Contrast enhanced computed tomography of the chest ruled out a pulmonary embolus but revealed an unexpected small subepicardial aneurysm (SEA) in the lateral left ventricular wall which was confirmed on cardiac magnetic resonance imaging. Intraoperative palpation of the left lateral wall was guided by the cardiac MRI and CT findings and confirmed the presence of focally thinned and weakened myocardium, covered by epicardial fat. An aneurysmorrhaphy was subsequently performed in addition to coronary bypass surgery and a mitral valve repair. The patient was discharged home on post operative day eight in good condition and is feeling well 2 years after surgery
