This study aims to analyze the asymmetric relation between renewable energy consumption and CO₂ emissions in China using the STIRPAT-Kaya-EKC framework. To delve into the asymmetric effect of renewable energy consumption on the environment, the non-linear ARDL model is used. The results of this study confirm the asymmetric impact of renewable energy on the environment in the long run as well as in the short run. However, the negative shocks to renewable energy have a greater detrimental influence on the environment than the benign effect due to the positive shock to renewable energy. Population growth affects the environment in the short run, whereas technology only affects environment quality in the long run. Moreover, the study supports the EKC theory in China. This research emphasizes that the administration can improve the economy’s lifespan by allocating substantial funds to establish legislation to maintain a clean environment by subsidizing renewable energy infrastructure and research and innovations for low-carbon projects.

Objective: To determine the frequencies of different vascular etiologies and clinical presentations in post-partum women with suspected stroke. Study Design: Cross-sectional study. Setting: Department of Medicine, Bahawal Victoria Hospital, Bahawalpur. Period: November 2022 to May 2023. Material & Methods: A total of 117 female patients aged between 18-45 years in post-partum period of 30 days after delivery having clinical diagnosis of suspected stroke were included. All patients were evaluated and clinical presentation and frequency of different vascular etiologies were noted. Results: In 117 women, the mean age was 32.01±5.67 years while 59 (50.4%) women were aged ≤35 years of age. Headache was found in 61 (52.1%), seizures 56 (47.9%), altered consciousness 26 (22.2%) and weakness in 16 (13.7%) patients. Frequencies of different vascular etiologies in post-partum women with suspected stroke were cerebral venous sinus thrombosis in 21 (17.9%), arterial thrombosis 7 (6.0%) and hemorrhagic stroke in 89 (76.1%) patients. Conclusion: Hemorrhagic stroke was the most common vascular etiology whereas headache was the commonest clinical presentation in post-partum women with suspected stroke.

Objective: To determine the frequency of cirrhotic cardiomyopathy in decompensated liver cirrhosis patients. Study Design: Descriptive, Cross-sectional. Setting: Department of Medicine, Bahawal Victoria Hospital, Bahawalpur. Period: February 2022 to August 2022. Material & Methods: Patients of either gender having age between 25-65 years with decompensated liver cirrhosis (duration >6 months) were analyzed. Demographic and clinical characteristics of each patient were recorded at the time of the inclusion. Then, echocardiography was done in each patient by consultant cardiologist and presence or absence of cirrhotic cardiomyopathy was noted. Results: In a total of 92 patients, 54 (58.7%) were male and 38 (41.3%) were female with male to female ratio as 1.4:1. The mean age was 42.92±8.72 years while 57 (61.96%) patients were aged between 25 to 45 years. The mean duration of disease was 8.52±2.48 months. The mean body mass index was 27.46±2.97 kg/m2. Diabetes was noted in 28 (30.4%) patients while 35 (38.0%) had hypertension. Frequency of cirrhotic cardiomyopathy in patients with decompensated liver cirrhosis was found in 38 (41.3%). Conclusion: This study concluded that the frequency of cirrhotic cardiomyopathy in decompensated liver cirrhosis patients is quite high.
