Background Tranexamic acid reduces surgical bleeding and reduces death due to bleeding in patients with trauma. Meta-analyses of small trials show that tranexamic acid might decrease deaths from gastrointestinal bleeding. We aimed to assess the effects of tranexamic acid in patients with gastrointestinal bleeding. Methods We did an international, multicentre, randomised, placebo-controlled trial in 164 hospitals in 15 countries. Patients were enrolled if the responsible clinician was uncertain whether to use tranexamic acid, were aged above the minimum age considered an adult in their country (either aged 16 years and older or aged 18 years and older), and had significant (defined as at risk of bleeding to death) upper or lower gastrointestinal bleeding. Patients were randomly assigned by selection of a numbered treatment pack from a box containing eight packs that were identical apart from the pack number. Patients received either a loading dose of 1 g tranexamic acid, which was added to 100 mL infusion bag of 0•9% sodium chloride and infused by slow intravenous injection over 10 min, followed by a maintenance dose of 3 g tranexamic acid added to 1 L of any isotonic intravenous solution and infused at 125 mg/h for 24 h, or placebo (sodium chloride 0•9%). Patients, caregivers, and those assessing outcomes were masked to allocation. The primary outcome was death due to bleeding within 5 days of randomisation; analysis excluded patients who received neither dose of the allocated treatment and those for whom outcome data on death were unavailable. This trial was registered with Current Controlled Trials, ISRCTN11225767, and ClinicalTrials.gov, NCT01658124.

Background Tranexamic acid reduces blood loss in surgery and the risk of death in trauma patients. Meta-analyses of small trials suggest that tranexamic acid decreases the number of deaths from gastrointestinal bleeding, but these meta-analyses are prone to selection bias. Objective The trial provides reliable evidence of the effect of tranexamic acid on mortality, rebleeding and complications in significant acute gastrointestinal bleeding. Design A multicentre, randomised, placebo-controlled trial and economic analysis. Patients were assigned by selecting one treatment pack from a box of eight, which were identical apart from the pack number. Patients, caregivers and outcome assessors were masked to allocation. The main analyses were by intention to treat. Setting The setting was 164 hospitals in 15 countries, co-ordinated from the London School of Hygiene & Tropical Medicine. Participants Adults with significant upper or lower gastrointestinal bleeding (n = 12,009) were eligible if the responsible clinician was substantially uncertain about whether or not to use tranexamic acid. The clinical diagnosis of significant bleeding implied a risk of bleeding to death, including hypotension, tachycardia or signs of shock, or urgent transfusion, endoscopy or surgery. Intervention Tranexamic acid (a 1-g loading dose over 10 minutes, then a 3-g maintenance dose over 24 hours) or matching placebo. Main outcome measures The primary outcome was death due to bleeding within 5 days of randomisation. Secondary outcomes were all-cause and cause-specific mortality; rebleeding; need for endoscopy, surgery or radiological intervention; blood product transfusion; complications; disability; and days spent in intensive care or a high-dependency unit. Results A total of 12,009 patients were allocated to receive tranexamic acid (n = 5994, 49.9%) or the matching placebo (n = 6015, 50.1%), of whom 11,952 (99.5%) received the first dose. Death due to bleeding within 5 days of randomisation occurred in 222 (3.7%) patients in the tranexamic acid group and in 226 (3.8%) patients in the placebo group (risk ratio 0.99, 95% confidence interval 0.82 to 1.18). Thromboembolic events occurred in 86 (1.4%) patients in the tranexamic acid group and 72 (1.2%) patients in the placebo group (risk ratio 1.20, 95% confidence interval 0.88 to 1.64). The risk of arterial thromboembolic events (myocardial infarction or stroke) was similar in both groups (0.7% in the tranexamic acid group vs. 0.8% in the placebo group; risk ratio 0.92, 95% confidence interval 0.60 to 1.39), but the risk of venous thromboembolic events (deep-vein thrombosis or pulmonary embolism) was higher in tranexamic acid-treated patients than in placebo-treated patients (0.8% vs. 0.4%; risk ratio 1.85, 95% confidence interval 1.15 to 2.98). Seizures occurred in 38 patients who received tranexamic acid and in 22 patients who received placebo (0.6% vs. 0.4%, respectively; risk ratio 1.73, 95% confidence interval 1.03 to 2.93). In the base-case economic analysis, tranexamic acid was not cost-effective and resulted in slightly poorer health outcomes than no tranexamic acid. Conclusions Tranexamic acid did not reduce death from gastrointestinal bleeding and, although inexpensive, it is not cost-effective in adults with acute gastrointestinal bleeding. Future work These results caution against a uniform approach to the management of patients with major haemorrhage and highlight the need for randomised trials targeted at specific pathophysiological processes. Limitations Although this is one of the largest randomised trials in gastrointestinal bleeding, we cannot rule out a modest increase or decrease in death due to bleeding with tranexamic acid.

Objective: To determine health related quality of life (HRQOL) of medical students and its correlation with their academic performance. Methods: Cross sectional study at Services Institute of Medical Sciences, included students of 4th and final year MBBS, who filled SF-36 proforma of HRQOL. Scores of 8-domains and of physical component and mental component summary were determined. Marks in all professional examinations were used to stratify students as high performers (≥ 70% marks) and average performing students (< 70%). HRQOL scores was correlated with academic performance using unpaired student’s t-test. Results: Among 267 students included, mental health score (56.2±21.3) was lower than physical health component score (69.03±18.5). Role limitation due to emotional health (RE) (44.81), Vitality (VT) (54.19) and general health perception (GH) (58.89) had lower scores among 8domains of questionnaire. Female students had significantly lower scores in role limitation due to emotional problems (p value <0.04), vitality (<0.05), bodily pain (p value <0.05) and general health perception (p value<0.03) than male students. Physical health and role limitation due to physical health domains were better in high performing students. Conclusion: Mental health of medical students is suboptimal, especially among female students. Students with better physical health have better academic performance.

Intimate partner violence (IPV) is a public health and human rights issue with the social and economic impacts felt by women. Punjab is a male-dominated society, where partner violence is generally accepted as a cultural norm and viewed as normal behavior within a marriage. It stems from attitudes that partner violence is a private matter and usually a justifiable response to misbehavior on the part of the wife. The focus of the current study is to investigate the impact of this cultural norm in acceptability attitude of women toward IPV in Punjab province. A large-scale sample size of more than 46,000 from Multi-Indicator Cluster Survey (MICS) 2018 has been used. The impact of the cultural norm on the wife-beating attitude has been investigated in five dimensions: wife going out without telling him, neglecting the children, arguing with him, refusing to have sex with him, and burning the food. The logistic regression results indicate that wife-beating is accepted as a community norm. It has been found that if wife-beating is accepted by community, then the individual female is more than 3 times more likely to consider it justifiable in all five dimensions. The other important factors are education level, household wealth, ethnicity, media exposure, and wife–husband age difference. The level of education of women plays the most important role in rejecting the wife-beating norm, as an increase in level of education is associated with an increase in the probability of rejecting the wife-beating. So, the current study suggests that there is a dire need to increase the female education level to overcome this issue.
