Application of Computed Tomography Perfusion Imaging-guided Mechanical
Thrombectomy in Ischemic Stroke Patients with Large Vessel Occlusion beyond
the Therapeutic Time Window
Authors: Xiang Shifeng , Su Ya , Li Shuyuan , Yang Sujun , Wu Yiping
Published: June 2023

Introduction:

To explore the feasibility of applying computed tomography perfusion (CTP) imaging-guided mechanical thrombectomy in acute ischemic stroke patients with large vessel occlusion beyond the therapeutic time window.

Methods:

The clinical data of acute cerebral infarction patients with large vessel occlusion who were beyond the therapeutic time window and admitted to Handan Central Hospital from January 2021 to March 2022 were retrospectively analyzed. All patients were assessed by the National Institutes of Health Stroke Scale (NIHSS) and were examined by one-stop CTP imaging. The preoperative onset time of the disease was more than 6 h. Fourteen patients underwent magnetic resonance imaging examination at the same time. Fifty-four patients were retrospectively divided into two groups based on the treatment methods: the mechanical thrombectomy group had 21 patients and the conservative treatment group had 33 patients. NIHSS scoring and computed tomography scan were performed before treatment, 6 h, 24 h, 7 days, and 30 days after treatment.

Results:

The NIHSS scores of the patients with acute cerebral large vessel occlusion who underwent CTP imaging-guided mechanical thrombectomy at 6 h, 24 h, 7 days, and 30 days after treatment were compared with those of the conventional treatment group. The NIHSS score of the mechanical thrombectomy group was significantly better, and the difference was statistically significant (P < 0.05). In terms of the prognosis rate and expansion rate of infarct core volume, the patients of the mechanical thrombectomy group had a better prognosis, and the difference was statistically significant (P < 0.05). Artificial intelligence-assisted CTP diagnosis can facilitate the automatic evaluation of diseases and enable quick judgments that are independent of radiologists evaluation, but it may pose a problem in the determination of infarct core volume (either being too high or too low).

Conclusion:

It is of great significance to apply CTP imaging in guiding the mechanical thrombectomy procedure in acute stroke patients with large vessel occlusion who are beyond the therapeutic time window.

The PT-31 molecule, a potential antipsychotic, has demonstrated promising results when orally administrated to in vivo models. A recent study suggested the genotoxic and mutagenic po-tential of PT-31 after acute treatment by intraperitoneal route. This study aimed to evaluate PT-31 potential of inducing genotoxic or mutagenic damage after acute oral administration. For that, adult males and females Balb/C mice were treated acutely by oral administration with vehicle or PT-31 in three different doses (10, 20, and 40 mg kg-1). After 24 hours from PT-31 administration, animals were euthanized for performing the comet and micronucleus assays. None of the tested groups of PT-31 presented a significant increase in damage index and MN frequency. However, they presen-ted the following tendency on damage index: females presented a tendency at 40 mg kg-1 and males at 20 mg kg-1. Regarding the MN assay, male mice at the highest dose of 40 mg kg-1 presented a tendency of increased MN frequency. Also, there was a significant increase in PCE/NCE ratio in male mice. Results suggest that the male mice group presented higher susceptibility to damage. The tendency of increased damage to DNA and MN frequency suggests that the molecule PT-31 may induce reparable damage to DNA, and these DNA strand repairs may have originated from the MN. However, significant genotoxic and mutagenic effects were not observed. This study reinforces the atypical profile of the molecule as much as its safety by oral route administration.

Reading Rage: Theorising the Epistemic Value of Feminist anger
Authors: Wallaert Sigrid
Published: June 2023

With the #MeToo movement and the Women’s Marches behind us, it has become clear that women are angry. This anger is often criticised for being disruptive or uncommunicative, with calm rationality being praised as a superior alternative. In this article, I use the framework of Fricker’s (2007) Epistemic Injustice to examine the communicative disadvantages and merits of what I call feminist anger. I explain how feminist anger can be subject to both testimonial and hermeneutical injustices, but that this does not mean it should not be used to communicate. Importantly, feminist anger can challenge the patriarchal status quo and it can provide an epistemic bridge towards hermeneutical justice. By listening to feminist anger, both our own and others’, we can get one step closer to epistemic equality.

Phase transitions in monoclinic ZrO-=SUB=-2-=/SUB=-
Authors: Gorelov V. P.  , Belyakov S. A.  , Abdurakhimova R. K.
Published: June 2023

Zirconia ZrO2 is one of the most important modern materials, but its use faces the problem of complex polymorphism. It is generally accepted that, under normal conditions, it exists in the monoclinic form P2_1/c (N 14), which undergoes an extended martensitic transformation into the tetragonal form P4_2/nmc (N 137) when heated above 1000oC. However, the group-theoretic analysis forbids a direct transition between these space groups and requires at least two intermediate forms. The experiment carried out in this work using structure-sensitive methods (dilatometry and electrical conductivity) indeed revealed the existence of singular points on the temperature dependences of expansion and conductivity in the temperature range of 350±20 and 730±20oC. This agrees with the literature data, which demonstrate singular points on the temperature dependences of the ZrO2 monoclinic lattice parameters. According to the dilatometry data, these transitions are phase transitions of the second order, which correlates with the obtained Raman data (measurements at temperatures up to 900oC in the range 60-900 cm-1), showing that the local structure changes slightly, therefore, the transitions occur within the framework of the monoclinic syngony. Keywords: ZrO2, monoclinic phases, phase transitions, dilatometry, electrical conductivity, Raman spectroscopy.
Gender Bias When Using Artificial Intelligence to Assess Anorexia Nervosa on Social Media: Data-Driven Study
Authors: Solans Noguero David , Ramírez-Cifuentes Diana , Ríssola Esteban Andrés , Freire Ana
Published: June 2023

Background

Social media sites are becoming an increasingly important source of information about mental health disorders. Among them, eating disorders are complex psychological problems that involve unhealthy eating habits. In particular, there is evidence showing that signs and symptoms of anorexia nervosa can be traced in social media platforms. Knowing that input data biases tend to be amplified by artificial intelligence algorithms and, in particular, machine learning, these methods should be revised to mitigate biased discrimination in such important domains.

Objective

The main goal of this study was to detect and analyze the performance disparities across genders in algorithms trained for the detection of anorexia nervosa on social media posts. We used a collection of automated predictors trained on a data set in Spanish containing cases of 177 users that showed signs of anorexia (471,262 tweets) and 326 control cases (910,967 tweets).

Methods

We first inspected the predictive performance differences between the algorithms for male and female users. Once biases were detected, we applied a feature-level bias characterization to evaluate the source of such biases and performed a comparative analysis of such features and those that are relevant for clinicians. Finally, we showcased different bias mitigation strategies to develop fairer automated classifiers, particularly for risk assessment in sensitive domains.

Results

Our results revealed concerning predictive performance differences, with substantially higher false negative rates (FNRs) for female samples (FNR=0.082) compared with male samples (FNR=0.005). The findings show that biological processes and suicide risk factors were relevant for classifying positive male cases, whereas age, emotions, and personal concerns were more relevant for female cases. We also proposed techniques for bias mitigation, and we could see that, even though disparities can be mitigated, they cannot be eliminated.

Conclusions

We concluded that more attention should be paid to the assessment of biases in automated methods dedicated to the detection of mental health issues. This is particularly relevant before the deployment of systems that are thought to assist clinicians, especially considering that the outputs of such systems can have an impact on the diagnosis of people at risk.

Authors: SAGAR TAMILISETTI VIDYA , BYNDOOR YATISH , P MADHAV
Published: June 2023

Objective: The objective of the study is to compare dexmedetomidine with clonidine as adjuvants to ropivacaine in epidural anesthesia in the onset of sensory and motor blockade, duration of post-operative analgesia, level of sedation, and occurrence of side effects.
Methods: This study was a prospective randomized observational and comparative study. Sixty patients of age between 20 and 50 years with the American Society of Anesthesiologists grade I and II physical status belonging to both sexes undergoing abdominal surgeries under epidural anesthesia are included; patients were allocated randomly into two groups comprising 30 patients in each group. Group A patients are given injection dexmedetomidine, added to ropivacaine and Group B patients are given injection clonidine, added to ropivacaine by epidural route. Following parameters were observed intra and post-operatively: Onset of sensory and motor blockade and duration of motor blockade, level of sedation, duration of analgesia, and side effects. All data are presented in tabular form as mean ± standard deviation. The analysis is done by unpaired t-test. Statistical analysis is done using SPSS software.
Results: Mean time of onset of sensory blockade in Group A was 9.50 min with standard deviation of 1.85 and in Group B was 9.48 min with standard deviation of 1.60. Mean time of onset of motor blockade in Group A was 20.66 min with standard deviation of 2.83 and in Group B was 20.48 min with standard deviation of 2.52. Mean duration of analgesia in Group A was 312.66 min with standard deviation of 22.02 and in Group B was 314.20 min with standard deviation of 24.58. There is no statistical difference between two groups in the level of sedation which was assessed by Wilson’s sedation scale. Side effects most commonly observed are hypotension and bradycardia.
Conclusion: We conclude that both dexmedetomidine and clonidine are similar in efficacy and tolerability as adjuvants in the onset of sensory and motor blockade and post-operative analgesia when added to ropivacaine in epidural anesthesia.

Objective: The aim of the study was to study the prescription pattern of prophylactic antiemetics in breast cancer patients.
Methods: A retrospective observational study was carried out. Over a period of 3 months, all chemotherapy order sheets of breast cancer patients were collected and evaluated for prophylaxis of chemotherapy-induced nausea and vomiting (CINV). We compared each antiemetic drug used for CINV prophylaxis with international antiemetic guidelines, the National Comprehensive Cancer Network (NCCN).
Results: A total of 103 breast cancer patients were included in the study, for which 141 chemotherapy physician prescriptions included antiemetic drugs. Approximately 51.06% of anticancer agents had high emetic risk, 2.13% had moderate emetic risk, and 43.26% and 3.55% of anticancer agents had low and minimal emetic risk, respectively. Most frequently prescribed anticancer drug was paclitaxel 49 (34.75%). About 43.97% of the antiemetic regimen were found following NCCN guidelines.
Conclusion: The development of institutional policy for assessment and guidance of the chemotherapy-induced nausea and vomiting prophylaxis may improve the consistency between antiemetic prescribing and guidelines.
TO EVALUATE THE VARIOUS RISK FACTORS RESPONSIBLE FOR ROAD TRAFFIC ACCIDENTS IN PUNJAB – A DESCRIPTIVE STUDY
Authors: BAL VINEET , KAUR JASWANT , SINGH TEJINDER
Published: June 2023

Objective: Evidence from research suggests that human factors and the road environment are among the most frequent contributors to the occurrence of road traffic accidents (RTAs). Hence, traffic rule and various policies, alike have strengthened their efforts to cope with this public health burden. Yet, still little is known about the factors contributing to the high number of RTAs. In this study, we tried to find out the various risk factors responsible for road accidents in the Punjab region.
Methods: The present study was conducted in Guru Nanak Dev Hospital, Amritsar, involving 1425 patients who were admitted to the Emergency Department from January 1st, 2012, to December 31st, 2012, due to injuries in RTAs.
Results: In our study, it seems that most of the cases were in the age group of 15–44 years. In all the age groups, males were the predominant victims with male-to-female ratio of 5.72:1. Majority of cases belonged to an upper–lower socioeconomic group, according to the Kuppuswamy scale and the major proportion of accidents occurred during the morning and evening busy hours of the day hours. Out of a total of 893 drivers, 858 (96.08%) had no knowledge about the speed limit prescribed for the road or speed.
Conclusion: There appears to be a large number of behavioral issues and a lack of knowledge that contributes significantly to the road accident rates in the Indian states. Hence, there is a need for policy intervention. Most effective measures used to reduce the number of accidents, in descending order of magnitude, are how strictly the traffic police enforce the law, more levels of penalties, and more traffic police, including more speed measuring devices.
TIME-TREND ANALYSIS OF DENGUE FEVER IN JAIPUR – A RECORD-BASED STUDY
Authors: Kukreja Srishti , Sharma Pankaj kumar , Sunda Jagdish Kumar , Meena Sadhana , Baig Vaseemnaheed
Published: June 2023

Introduction: Dengue is a vector-borne disease and is a major public health threat globally. The number of dengue cases reported to the World Health Organization increased over 8 fold over the past two decades, from 505,430 cases in 2000 to 5.2 million in 2019. The total number of cases seemingly decreased during years 2020 and 2021, as well as for reported deaths. However, the data are not yet complete and COVID-19 pandemic might have also inhibited case reporting in several countries. This record-based study was planned to study the annual and seasonal trend of dengue fever (DF) and effect of COVID-19 on reporting of DF.
Methods: The record-based analysis was done by collecting data from the CMHO after taking informed consent from the Chief Medical and Health Officer, Jaipur. Data from the past 5 years (i.e., 2017–2021) were collected to study the annual and seasonal trends of dengue in Jaipur. Descriptive statistics was expressed in percentage and proportions. Data were entered in Microsoft Excel and analyzed using Epi info version 7.2.2.6 (software).
Results: The number of cases increased from 2017 to 2018 with a slight decrease in 2019. There is sudden decrease in the number of cases from 2019 to 2020 which clearly shows the effect of COVID-19 pandemic. It was noticed that the number of cases starts increasing from August and reaches a peak in October and then starts decreasing.
Conclusion: Dengue is present throughout the year but becomes a public health problem in the third quarter of year. Under-reporting of dengue cases and similar clinical presentation as COVID-19 made situation more difficult in its diagnosis and management that ultimately results in less cases reported in 2020.

A semi-structured questionnaire of 21 items was administered to 840 patient’s accompanying persons/caretaker selected as per inclusion/exclusion criteria. Information on demographic variables of the respondents intheir knowledge about ionizing radiation effects/hazard, radiation protection measures and source of their knowledge on ionizing radiation were taken and collected data used in the study by applying descriptive statistical analysis.
Results: Majority of the participants in our study were male 548 (63.3%). Most of the participants, 635 (75.6%), did not have knowledge of ionizing radiation. Only 320 (38%) knew that ionizing radiation is hazardous. The majority of the participants, 399 (76.7%), were informed about radiation by the radiographers, while 121 (23.2%) read about it. A larger number of the participants, 620 (73.8%), had no idea about the meaning of radiation protection. The majority of the participants, 678 (80.2%), assisted their relatives during the examination. Most of the participants, 676 (80.1%), have seen the radiation warning sign before.
Conclusion: This study showed that there is a low level of knowledge and awareness of radiation hazards and protective measures among patients’ accompanying persons or caretakers. It is obvious that public education via new papers, TV, holdings, etc. will contribute immensely to the spreading of awareness of the harmful effects of ionizing radiation and the measurement of for radiation protection measures.

Authors: Pujari Mayura D , Kakade Pooja D , Benare Aparna G
Published: June 2023

Aims and Objectives: The aims of the study were to compare efficacy and side effects of popliteal block and unilateral spinal anesthesia in patients undergoing below knee surgeries.
Methods: This was a comparative study comprising patients undergoing below knee surgeries. Sixty patients were divided into two groups depending on whether surgery was done under unilateral spinal anesthesia (Group SA) or popliteal block (Group PB). The parameters compared between the studied groups included hemodynamic changes, onset of motor block, onset and duration of analgesia, duration of motor block, onset of pain, and amount of rescue analgesia required. Side effects such as bradycardia, hypotension, cardiac arrhythmia, and urinary retention were compared between the two groups. SSPS 22.0 was used for statistical analysis and p<0.05 was taken as statistically significant.
Results: There were 14 (46.67%) males and 16 (53.33%) females, whereas, in Group PB, there were 13 (43.33%) males and 17 (56.67%) females. Mean age of patients in Group SA was found to be 42.93±16.79 and 39.57±14.05 in Group PB. The mean age and gender distribution and ASA grades of patients in both the groups were found to be comparable with no statistically significant difference. The mean duration of sensory as well as motor block was found to be significantly less in Group SA as compared to Group PB and the difference was statistically highly significant (p<0.001). Group PB showed a better hemodynamic as well as analgesic profile as compared to Group SA. The analgesic requirement in first 24 h was more in Group SA as compared to Group PB and the difference was statistically highly significant (p<0.001). Adverse effects in both the groups were comparable (p>0.05).
Conclusion: Popliteal block provides better analgesia and hemodynamic stability as compared to unilateral spinal anesthesia and, hence, can be considered preferred mode of anesthesia in patients undergoing lower limb surgeries.v

Published: June 2023

Objectives: The aim of the study was to find out the efficacy of thoracic segmental spinal anesthesia combined with unilateral erector spinae block in patients undergoing unilateral modified radical mastectomy and axillary lymph node dissection
Methods: This was a prospective cohort study in which 40 patients with carcinoma breast undergoing modified radical mastectomy with axillary dissection under thoracic segmental spinal anesthesia combined with unilateral erector spinae block were included on the basis of a predefined inclusion and exclusion criteria. Erector spinae plane block was given at T5 level and thoracic spinal anesthesia was then given at T5–T6 level in the same position by median or paramedian technique. Patients were assessed for severity of pain by visual analog scale score till 24 h of surgery.
Results: The mean age of studied cases was found to be 44.12±10.04 years. Mean weight of studied cases was 54.38±9.8 kg, whereas mean duration of surgery was found to be 98.24±16.86 min. The most common American Society of Anesthesiologists (ASA) grade to which patients belonged was found to be ASA III (55%) followed by ASA II (30%) and ASA I (15%). Eleven patients required rescue analgesia within first 24 h after surgery and mean doses of rescue analgesia in 1st 24 h after surgery was found to be 0.92±0.48. Four (10%) patients developed hypotension, whereas three (7.5%) patients had bradycardia. However, all these 7 (17.5%) had transient bradycardia or hypotension which could be managed by IV Atropine or IV mephentermine and fluid bolus.
Conclusion: Thoracic segmental spinal anesthesia combined with unilateral erector spinae block is an excellent option for patients undergoing modified radical mastectomy with axillary dissection.

Published: June 2023

Aims and Objectives: The aims and objectives of the study are to compare the Ranson’s scoring system with APACHE II score in predicting the severity of acute pancreatitis.
Methods: 50 cases having acute pancreatitis were included in this study on the basis of a predefined inclusion and exclusion criteria. Institutional ethical committee was approved the study. The duration of study was 2 years. Informed consent was obtained from the patients. Assessment of severity of pancreatitis was done on the basis of Ranson’s scoring as well as APACHE II score. Final severity score of the patients on the basis of both the scoring systems was assessed to determine the efficacy of each scoring system in predicting the severity.
Results: Out of these 50 cases, there were 37 (74%) males and 13 (26%) females. The mean age of affected cases was found to be 36.86±7.91 years. The most common etiological factor was chronic alcoholism which was seen in 22 (44%) patients followed by biliary tract disease or stones (24%), hypertriglyceridemia (14%), post ERCP (2%), idiopathic (14%), and autoimmune pancreatitis (2%). Mild and severe pancreatitis was seen in 35 (70%) and 15 (30%), respectively. APACHE II score was found to be having more sensitivity and positive predictive value for the diagnosis of severe pancreatitis as compared to Ranson’s score. There was no significant difference in specificity, negative predictive value, and accuracy as determined by Ranson’s and APACHE II Score.
Conclusion: APACHE II score is better in predicting severity of acute pancreatitis as it is found to have a better sensitivity and positive predictive value for the diagnosis of severe pancreatitis as compared to Ranson’s score.

Objectives The purpose of this study is to analyze achievements and limitations of Educational Community operation and explore future directions for improvement of school-community partnership. Methods The study applied qualitative meta-synthesis in analyzing the achievements and limitations through 11 qualitative studies. Specific framework for the analysis were curriculum linkage between school and local community, public-private-school partnership, and autonomy of local community and expansion of education to community. Results The results of the meta-synthesis showed that first, Educational Community had achievements in linking the school and community and providing various curriculum to the students. However, teachers, parents, and students had to face a dilemma between the old school based education and the new form of Educational Community, which created limitations. Second, a system of public-private-school partnership was found as a achievement of the Educational Community operation. At the same time, with different structure and culture of different organizations, practical partnership was not in place. Finally, Educational Community contributed to community members’ participation in education, which is a great achievement compared to a closed school-based education. However, sustainability of community members’ participation was a question remained to be resolved. Conclusions The practical and policy implications are: first, Educational Community require practical support to facilitate the operation of the curriculum that are created through school and community. Second, the results suggest the need for coordinating roles of public-private-school partnership for effective operation of Educational Community. Lastly, Educational Community needs to adopt an integrated approach of school and community to ensure the sustainability of its’ accomplishments.
