    Gender inclusion and female participation in STEM courses have always been challenging in a patriarchal country like Pakistan. Women are often underrepresented in engineering fields, as engineering fields are usually considered manly. Female students confront many challenges, be it workplace or educational institutes. Some of the self-perceived and determined challenges are discussed in this study. As determined through this research study, factors affecting female participation are low STEM confidence, Gender disparity, Social and Academic Support, and Learning Environment. Empirical Evidence is collected using a questionnaire with 25 items based on the Likert scale. The dependent variables are STEM Confidence and Learning Environment, whereas the independent variables are Social and Academic Support. Participants included 170 female UG and PG engineering students from 4 universities in Pakistan. Data were collected through the Questionnaire, which included an online survey. Correlation method and statistical test MANOVA were applied, using SPSS 21 to determine the effect of social and academic support on the STEM confidence of female students and to find a relationship between the variables. Results indicate a positive correlation between the variables STEM confidence and social and academic Support and Learning environment, whereas a slight correlation has been observed between social Support and LE. MANOVA results indicated a significant effect of Social and Academic Support on the STEM confidence of female students. Empirical Evidence shows that Social and academic support can affect the STEM of female engineering students, and the LE of females can also be affected by social and academic Support

    Calcium is a second messenger which is required for regulation of many cellular processes. However, excessive elevation or prolonged activation of calcium signaling would lead to cell death. As such, selectively regulating calcium signaling could be an alternative approach for anti-cancer therapy. Recently, we have identified an effective analogue of resveratrol, (Z)3,4,5,4′-trans-tetramethoxystilbene (TMS) which selectively elevated the intracellular calcium level in gefitinib-resistant (G-R) non-small-cell lung cancer (NSCLC) cells. TMS exhibited significant inhibitory effect on G-R NSCLC cells, but not other NSCLC cells and normal lung epithelial cells. The phosphorylation and activation of EGFR were inhibited by TMS in G-R cells. TMS induced caspase-independent apoptosis and autophagy by directly binding to SERCA and causing endoplasmic reticulum (ER) stress and AMPK activation. Proteomics analysis also further confirmed that mTOR pathway, which is the downstream of AMPK, was significantly suppressed by TMS. JNK, the cross-linker of ER stress and mTOR pathway was significantly activated by TMS. In addition, the inhibition of JNK activation can partially block the effect of TMS. Taken together, TMS showed promising anti-cancer activity by mediating calcium signaling pathway and inducing apoptosis as well as autophagy in G-R NSCLC cells, providing strategy in designing multi-targeting drug for treating G-R patients

    Objective: To assess the utility of the Cardiac Children\u27s Hospital Early Warning Score (C-CHEWS) in the early detection of deterioration.Design: Single-center longitudinal pilot study.Setting: Pediatric cardiac ICU (PCICU), Aga Khan University.Interventions: C-CHEWS and Inadequate Oxygen Delivery (IDO2) Index calculation every 2 hours.Patients: A total of 60 children (0 d to 18 yr old).Measurements and main results: A single-center longitudinal pilot study was conducted at PCICU. All postoperative extubated patients were assessed and scored between 0 and 11, and these scores were then correlated with the IDO2 index data available from the T3 platform. Adverse events were defined as a need for cardiopulmonary resuscitation, or reintubation, and death. A total of 920 C-CHEWS and IDO2 scores were analyzed on 60 patients during the study period. There were 36 males and 24 females, and the median age of the study population was 34 months (interquartile range, 9.0-72.0 mo). Fourteen patients (23.3%) developed adverse events; these included 9 reintubations and 5 cardiopulmonary arrests, resulting in 2 deaths. The area under the curve (AUC) for C-CHEWS scores fell in an acceptable range of 0.956 (95% CI, 0.869-0.992), suggesting an optimal accuracy for identifying early warning signs of cardiopulmonary arrest. Whereas, IDO2 showed no discriminatory power to detect the adverse events with an AUC of 0.522 (95% CI, 0.389-0.652).Conclusions: The C-CHEWS tool provides a standardized assessment and approach to deteriorating congenital cardiac surgery patients in recognizing early postoperative deterioration

    Jeelo Dobara (Live Life Again): a cross-sectional survey to understand the use of social media and community experience and perceptions around COVID-19 vaccine uptake in three low vaccine uptake districts in Karachi, Pakistan

    Objective To gather preliminary insights through formative research on social media usage, and experiences, attitudes and perceptions around COVID-19 and COVID-19 vaccination in three high-risk, underserved districts in Karachi, Pakistan.Design Cross-sectional mixed-method design.Participants 392 adults (361 surveys and 30 in-depth interviews (IDI)) from districts South, East and Korangi in Karachi, Pakistan.Main outcome measures Social media usage and knowledge, perception and behaviour towards COVID-19 infection and vaccination.Results Using social media was associated with an increased probability of getting vaccinated by 1.61 units. Most of the respondents (65%) reported using social media, mainly to watch videos and/or keep in touch with family/friends. 84.76% knew of COVID-19 while 88.37% knew about the COVID-19 vaccination, with 71.19% reported vaccine receipt; reasons to vaccinate included belief that vaccines protect from the virus, and vaccination being mandatory for work. However, only 56.7% of respondents believed they were at risk of disease. Of the 54 unvaccinated individuals, 27.78% did not vaccinate as they did not believe in COVID-19. Despite this, 78.38% of respondents scored high on vaccine confidence. In IDIs, most respondents knew about COVID-19 vaccines: ‘This vaccine will create immunity in your body. Therefore, I think we should get vaccinated’, and over half knew how COVID-19 spreads. Most considered COVID-19 a serious public health problem and thought it important that people get vaccinated. However, there was a low-risk perception of self as only a little over half felt that they were at risk of contracting COVID-19.Conclusion With our conflicting results regarding COVID-19 vaccine confidence, that is, high vaccine coverage but low perception of risk to self, it is likely that vaccine coverage is more a result of mandates and coercion than true vaccine confidence. Our findings imply that interactive social media could be valuable in fostering provaccine sentiment
