Cureus 2021 Jan 16;13(1):e12733. Epub 2021 Jan 16.

Internal Medicine, Jinnah Postgraduate Medical Centre, Karachi, PAK.

Introduction Coronary artery bypass graft (CABG) is the most potent of surgical procedures; in this procedure, the narrowing of the coronary artery due to atherosclerotic plaque is bypassed by forming an alternate route for blood flow to the heart. There are various risk factors associated with the procedure. The aim of this study was to observe if postoperative outcomes are affected by preoperative hematocrit (hct) levels in patients. Methods  This longitudinal study was conducted from April 2019 to December 2019. Eighty-two (82) participants who were to undergo CABG surgery were divided into two groups based on their preoperative hct levels. Group 1 had 42 participants with lower levels of hct (less than 35.5% for women and 38.3% for men), whereas group 2 consisted of 40 participants with normal hct levels (greater than 35.5% for women and 38.3% for men). Results The results showed that participants undergoing CABG with lower than normal hct levels had increased blood loss through drainage as compared to participants who had normal hct levels (680.1 ± 301 mL vs. 500.7 ± 412 mL; p-value: 0.02). Group 1 participants also had an increased need for blood and blood product transfusion as compared to group 2 (3.2 ± 1.8 units vs. 1.8 ± 0.9 units; p-value: <0.0001). Furthermore, the participants in group 1 had longer stays in the ICU relative to the other group (5.2 ± 3.1 days vs. 3.4 ± 2.5 days; p-value: 0.003). Conclusion Based on our findings, patients who undergo CABG surgery with lower than normal hct levels are at increased risk of certain complications, including excessive blood loss, need for transfusion, and increased duration of ICU stay. Therefore, preoperative hct levels should be routinely checked in patients undergoing CABG to prevent these complications.

Depression and Anxiety as a Risk Factor for Myocardial Infarction.

Cureus 2019 Nov 3;11(11):e6064. Epub 2019 Nov 3.

Internal Medicine, Jinnah Postgraduate Medical Centre, Karachi, PAK.

Introduction:  Patients having a cardiovascular disease experience negative states of psychology. An increased incidence of coronary artery disease is attributed to both depression and anxiety.

Materials And Methods:  In this retrospective study, the Hospitalized Anxiety and Depression Scale (HADS) was used to determine anxiety and depression in stable patients of myocardial infarction (MI) at the time of their discharge. All responses were based on the patients' perceptions two weeks prior to acute MI event. SPSS version 21.0 was used for data entry and analysis.

Results: The mean age of the participants in our study was 49.09±5.61 years. About 52.83% (n=28) and 58.49% (n=31) participants suffered from anxiety and depression two weeks prior to their myocardial infarction.

Conclusion: Depression and anxiety can be a risk factor for myocardial infarction in susceptible individuals. Attention should be given to mental well-being, and a multi-disciplinary management approach should be taken for these patients including psychiatry and psychology.

Evaluation of Risk Factors Associated with Reinfarction: A Multicenter Observational Study.

Cureus 2019 Nov 3;11(11):e6063. Epub 2019 Nov 3.

Internal Medicine, Jinnah Postgraduate Medical Centre, Karachi, PAK.

Introduction: Reinfarction after incidence of myocardial infarction is a serious complication and is responsible for high mortality. Various factors are responsible for reinfarction including smoking, prior procedures or surgeries, and use of medications such as aspirin, β-blocker, and angiotensin-converting enzyme Iihibitor or angiotensin receptor blockers.

Material And Methods: This prospective study was conducted with 243 participants. Participants were divided into two groups: patients who had a reinfarction during hospital and patients who did not.

Results: There were 142 (58.4%) men and 101 (41.6%) women in the study. A total of 17 (6.9%) patients had reinfarction. Age (68.4±10.9 vs. 64.4±11.8; 0.001), diabetes (47.05% vs. 22.12%; 0.02), and history of myocardial infarction (29.5% vs. 11.4%; 0.02) were identified as risk factors for reinfarction Conclusion: Our study reports that certain parameters such as age, obesity, diabetes mellitus,, and history of myocardial infarction can be used to assess the risk of reinfarction among these patients.

Effect of seedling age and water depth on morphological and physiological aspects of transplanted rice under high temperature.

J Zhejiang Univ Sci B 2005 May;6(5):389-95

Agricultural Research Institute, Dera Ismail Khan, NWFP, Pakistan.

To study the effect of high temperature, rice seedlings 20, 30, 40 and 50 d were kept at 5, 10, 15 and 20 cm water depth in a water pool. Meteorological findings indicated that water temperature varied up to 10 cm but became stable below this depth. Deep water inflicted higher tiller mortality, minimal increase in dry weight of aerial parts and leaf area, decrease in root length, and decrease in root dry weight especially at 20 cm water depth and produced an unbalanced T/R ratio (top versus root dry weight). However, deep water tended to increase plant length. These parameters, however, excel in shallow water. Older seedlings, with the exception of root dry weight, could not perform well compared to young seedlings in all physiological and morphological aspects. The study revealed that seedlings, particularly young ones, stand well in shallow water and can cope with high temperature.
