Smoking behaviour in post-acute myocardial infarction patients: cross-sectional study.

Introduction: Heart disease remains the leading cause of death in developed countries, and cigarette smoking contributes to a significant proportion of cardiovascular-related deaths. Abstaining from tobacco use is associated with a significant reduction in the risk of recurrent myocardial infarctions. Methodology: In this cross-sectional study, 384 participants post-acute myocardial infarction (MI) were recruited through random sampling to explore the associations between smoking status and intention to quit smoking. Data collection took place over a 6-month period at a tertiary care hospital, Islamabad, Pakistan. Results: The majority of participants were male (59.9%) and fell into the age category of 46-50 years (37.5%). Heavy daily smokers comprised the largest smoking group (41.6%), and non-ST-elevated MI was the most common subtype (40.1%). Intention to quit smoking varied among participants, with the pre-contemplation stage having the highest representation (19.3%), followed by contemplation (25.8%). Notably, a significant proportion of participants expressed no intention to quit smoking (35.4%). Conclusion: Multinomial logistic regression analysis identified current smoking as a significant predictor of intention to quit in the preparation and contemplation stages. Overall, this study underscores the importance of considering smoking behaviour when evaluating the intention to quit smoking post-MI and highlights the need for tailored interventions and support strategies to address smoking cessation in this population. These findings offer valuable insights for the development of effective strategies aimed at reducing persistent smoking following MI and improving patient outcomes.

Predictors of Health-Related Quality-of-Life Status Among Elderly Patients With Cardiovascular Diseases.

OBJECTIVES: Quality of life is an important patient-reported outcome in the care of older patients with chronic diseases owing to aging-associated limited physical activity and poor health status. The current study aimed to evaluate health-related quality of life and its predictors among elderly cardiac outpatients. METHODS: A descriptive, nonexperimental, cross-sectional study was carried out from May 2018 to October 2018 in outpatient departments of a tertiary-care hospital. The population under study were patients aged ≥65 years with at least 1 cardiovascular condition. The EQ-5D-3L (Euro QOL) and Barthel index were used to measure the quality of life and performance of activities of daily living, respectively. Linear regression analysis was performed by using SPSS version 21. RESULTS: Of a total of 386 patients, 198 patients (51.3%) reported impairment in the mobility domain, and 70.5% (n = 272) of patients indicated impairment in the depression domain. Mann-Whitney tests revealed EQ-5D scores, and visual analogue scale scores significantly differed by hospital admissions (P = .001), fall history (P < 0.001), and activities of daily living (P < .001). Kruskal-Wallis analysis revealed that EQ-5D index value and visual analogue scale score were significantly lower among patients who had comorbidities and who were exposed to polypharmacy (5-9 medications) (P < .001). In multivariate linear regression analysis, self-reported health (P = .006) and performance of activities of daily living (P < .001) were reported as influencing factors on health-related quality of life. CONCLUSION: Findings indicated poor quality of life among older patients with cardiovascular diseaese or heart diseases in Pakistan. Measures should be taken to improve patients' perception and to enhance awareness regarding the importance of doing daily living activities as a predictor of good quality of life.

Audit of antibiotic prophylaxis and adherence of surgeons to standard guidelines in common abdominal surgical procedures.

BACKGROUND: Prophylactic use of antibiotics before surgery is evidence-based practice for prevention of surgical site infections (SSIs). AIMS: To investigate adherence to and surgeons' perception of antibiotic prophylaxis guidelines. METHODS: A two-phase, cross-sectional prospective study conducted in two teaching hospitals. Phase 1: 6-month audit of prescriptions to investigate adherence rate to evidence-based guidelines. The important information was collected from medical charts through a predesigned proforma. Phase 2: self-administration questionnaire was used to investigate the surgeons' perception. Descriptive statistics, independent-sample Kruskal-Wallis test and multivariate linear regression analysis were performed using SPSS version 21.0. RESULTS: A total of 866 eligible surgical cases (acute appendectomy; n = 418; 48.2%), laparoscopic cholecystectomy (n = 278; 32.1%) and inguinal hernia (n = 170; 19.7%) were investigated. Surgical antibiotic prophylaxis was prescribed in 97.5% of procedures. Out of these, 9.5% adhered to guidelines with respect to correct choice, 40% for timing, and 100% for dose and route (optimal value 100%). Most patients received ceftriaxone (n = 503; 59.5%) as prophylactic antibiotic. The questionnaire (good internal consistency; α ≥ 0.7) was filled out by 200 surgeons. More than half (69%) of participants thought that antibiotics were overused. Most surgeons perceive that poor adherence to treatment guidelines is due to poor awareness, underestimation of infection, lack of consensus, and disagreement with guidelines recommendations. CONCLUSIONS: Surgeons have positive perception that antibiotics should be used according to guidelines recommendations. However, we found poor treatment adherence to antibiotic prophylaxis guidelines.

Audit of pre-operative antibiotic prophylaxis usage in elective surgical procedures in two teaching hospitals, Islamabad, Pakistan: An observational cross-sectional study.

An audit of the antibiotic prophylaxis in surgical procedures is the basic area of antimicrobial stewardship programme. The current research aimed to evaluate the adherence-proportion of the pre-operative antibiotic prophylaxis (PAP) practices in common elective surgical procedures. It was an eight-month (January 2017 to August 2017) observational cross-sectional patients' treatment record-based study conducted at two tertiary care teaching hospitals of Islamabad, Pakistan. We investigated the three most commonly performed elective general surgical procedures at the hospitals in adults aged > 18 years with no previous infection or surgery. The required data were extracted from the medical charts. Current prescribing practices were compared with the standard prescribing guidelines. A total of 660 (Government Hospital (GH), n = 330 and Private Hospital (PH), n = 330) procedures were observed. The most commonly performed elective general surgical procedures were laparoscopic cholecystectomy 307/660 (46.5%), followed by direct inguinal hernia 197/660 (29.8%) and total thyroidectomy 156/660 (23.6%). Non-use of PAP was observed in 64/660 (9.7%) cases. PAP was given to 90.3% (n = 596/660) cases (300/330 (90.9%) patients in GH and 296/330 (89.7%) in PH; P = 0.599). Based on the existing guidelines, the choice of antibiotics was correct in only 4.2% (25/596) patients (10/300; 3.3% cases at GH and 15/296; 5% at PH). The appropriate use of antibiotics was significantly greater in direct inguinal hernia (n = 19/193; 9.8%) cases compared with that in total thyroidectomy (n = 4/152; 2.6%) and laparoscopic cholecystectomy (n = 2/251; 0.8%) cases; P = 0.001. Compliance to the timing was only 51% (n = 304/596) of the total patients received PAP which was significantly lower in GH 97/300 (32.3%) as compared with that in PH 207/296 (69.9%); P = 0.001. Administration timing of antibiotics was observed to be more appropriate in total thyroidectomy (n = 79/152; 51.9%) cases than in laparoscopic cholecystectomy (n = 130/251; 51.8%) and direct inguinal hernia (n = 95/193; 49.2%) cases; P = 0.001. The route and dose were appropriate in accordance with the guidelines in all cases (100%). Most of the patients received ceftriaxone, a third-generation cephalosporin that is no longer recommended by the latest international guidelines. The current analysis revealed an alarmingly poor adherence rate with the guidelines in the three elective surgical procedures at both hospitals. To improve the situation, training and awareness programs about the antimicrobial stewardship interventions on the institutional level may be valuable.

Thrombotic microangiopathy associated with proteasome inhibitors.

The ubiquitin proteasome pathway plays a key role in cell cycle, function and survival. Bortezomib (BTZ) and Carfilzomib (CFZ) are the first two inhibitors of the proteasome pathway, indicated in treatment of patients with multiple myeloma. In the past few years, there have been few case reports that have highlighted the association between proteasome inhibitors (BTZ and CFZ) with acute kidney injury (AKI). In most of these case reports and initial trials, the underlying mechanism of AKI has been unclear. In this article, we discuss the association and pathogenesis of proteasome inhibitors-associated AKI. We also report the first case of CFZ-associated AKI with kidney biopsy evidence of thrombotic microangiopathy and the presence of microangiopathic hemolytic anemia.
