Usefulness of electrocardiography QT interval for prediction of left ventricular diastolic dysfunction: a cross-sectional study.

Heart failure (HF) is a leading cause of morbidity and mortality worldwide, with projections showing a further rise in incidence, impacting a decline in quality of life and the costs incurred in its diagnosis and treatment. The authors aim to establish the correlation between the prediction of left ventricular diastolic dysfunction based on a change in QT wave intervals. Methods: A cross-sectional at Holy-family Hospital, Rawalpindi Medical University, Pakistan. One thousand five hundred patients were referred for electrocardiography (ECG) for clinical suspicion of HF between May and July 2022. Ejection fraction (EF), lateral mitral annulus velocity (e'), mitral inflow early (E) and late (A) velocities, left ventricular filling pressure (E/e' ratio), and QT interval (QTc) was calculated. Odds ratios with a 95% CI (odds) were obtained by comparing QTc with all variables. Results: The patients were mostly middle-aged adults with a mean age of 30.27 (±7.64). Male to female ratio was nearly balanced, with 771 (51.4%) males included in the clinical survey. The ECG parameters were; QT interval-494.07 (±63.61), EF-57.11 (±11.96), early to atrial filling velocity ratio-0.71 (±0.20), and lateral mitral annulus velocity-8.29 (±1.64). Conclusion: The promising results for correlation between QT interval and ECG parameters, particularly EF and lateral mitral annulus velocity, should not be considered as the alternative in diagnosing left ventricular diastolic dysfunction thus far. Prolonged electrocardiographic QTc interval in patients with HF is useful in predicting diastolic dysfunction.

Clinicopathological correlation of aspartate aminotransferase-to-platelet ratio (APRI) and aspartate aminotransferase-to-alanine aminotransferase ratio (AAR) with survival in esophageal carcinoma patients: a retrospective cohort analysis of 951 patients.

Esophageal cancer is the eighth most prevalent cancer globally. Previously, several biomarkers have been used to predict the prognosis, although with variable reliability. Interestingly, it is noted that changes in liver function tests levels before and after neoadjuvant treatment are predictive in terms of cancer recurrence. Objectives: The objectives of the current study were to associate novel markers, including aspartate aminotransferase-to-platelet ratio (APRI) and aspartate aminotransferase-to-alanine aminotransferase ratio (AAR) with survival in esophageal malignancy. Materials and Methods: A retrospective study in a tertiary care hospital (single-center) included 951 patients having diagnosed esophageal carcinoma of any age group. Results: The median (interquartile range) age of study participants were 50 (38-60) years, including 43% males and 57% female patients, while the median (interquartile range) levels of AAR and APRI were 0.97 (0.81-1.25) and 0.19 (0.13-0.29), respectively. AAR was found to be higher in dysphagia for solids only and dysphagia for both liquids and solids rather than liquids only (P=0.002), while other associations included well-differentiated tumor grade (P=0.011), finding of esophageal stricture on esophagogastroduodenoscopy (P=0.015), and characteristic of mass on computerized tomography scan being both circumferential and mural (P=0.005). APRI was found to be higher in adenocarcinoma (P=0.038), and finding of circumferential±ulcerated mass on esophagogastroduodenoscopy (P<0.001). On survival analysis, adenocarcinoma (P<0.001), luminal narrowing (P=0.002), AAR greater than 1.0 (P=0.006), and APRI greater than 0.2 (P=0.007) were found to be poor survival predictors. On Cox proportional hazards regression, APRI was found to be more associated with poor survival than AAR (Hazard ratio: 1.682, 1.208-2.340, P=0.002). Conclusion: This study correlated clinical and pathological features of esophageal malignancy with noninvasive markers of hepatic function.

Assessment of knowledge and attitude of healthcare professionals regarding the use of telemedicine: A cross-sectional study from rural areas of Sindh, Pakistan.

Background: Telemedicine has proved its significance in the healthcare system, especially during the coronavirus disease 2019 (COVID-19) pandemic as it assists in the provision of early and effective healthcare to those in distant areas. This study aimed to assess the knowledge and attitude of healthcare professionals toward the use of telemedicine in the rural areas of Sindh, Pakistan. Materials and methods: The cross-sectional study was conducted with 212 healthcare professionals including physicians, consultants, surgeons, residents, dentists, and house officers working in public sector hospitals. The face-to-face method was used for data collection. Chi-square test and logistic regression analysis were applied to find the association between different variables and knowledge and practice of telemedicine using SPSS V 24. Results: The knowledge of participants regarding the usability of telemedicine and various tools used for the provision of medical services (video consultations, conferencing, use of applications, software, and online groups) was good. A total of 52.2% of participants showed agreement when they were questioned about being aware of online healthcare service provision. In this study, 52.8% of the participants practiced telemedicine by delivering healthcare services through online consultations. The majority of the participants were surgeons (25.9%), residents (23.1%), and physicians (18.9%). The internet (42.4%) and public media (25.9%) were the major sources of information for telemedicine. A total of 70.5% of participants suggested that strategies and efforts should be directed toward the enhanced implementation of telemedicine. Training in telemedicine as a source of information [OR = 13.02 (95% CI = 3.9-43.6), p < 0.001)] and awareness regarding the effect of telemedicine in healthcare quality [OR = 10.25 (95% CI = 2.9-35.4), p < 0.001)] remained the predicting factors for the practice of telemedicine among healthcare workers using multivariate regression analysis. Conclusion: Telemedicine has technologically revolutionized the medical sciences worldwide. The awareness level and usage of telemedicine were good among healthcare professionals in rural Sindh. Telemedicine should be utilized to provide quality healthcare in underprivileged areas by investing in infrastructure and education.

Diagnostic accuracy of Alvarado scoring system relative to histopathological diagnosis for acute appendicitis: A retrospective cohort study.

Background: Acute appendicitis (AA) is a surgical emergency that requires prompt diagnosis and suitable management. It may lead to complications resulting in mortality. To evaluate the diagnostic accuracy of the Alvarado scoring system (ASS) for acute appendicitis concerning histopathological data. Methodology: About 120 patients were selected for this study consisting of 96 males and 24 females age between 20 and 60. Alvarado scoring system is calculated for each patient after collecting data about demographics, laboratory findings, and clinical examination. Then, we compared it with histopathological diagnosis taking it as a gold standard. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated. SPSS version 20 was used for analyzing the data. Results: About 120 patients were included in our study. The male to female ratio was 3:1. Sensitivity and specificity were 83.3% and 41% respectively. While PPV and NPV were 85% and 41% respectively. The negative appendectomy rate was 21%. The area under the curve for receiving operating characteristics is 0.628. Conclusion: ASS is a useful diagnostic tool regarding sensitivity and positive predictive value, especially in developing countries. It is cheap, reliable, and can be easily applied.
