Predilation Ballooning in High Thrombus Laden STEMIs: An Independent Predictor of Slow Flow/No-Reflow in Patients Undergoing Emergent Percutaneous Coronary Revascularization.

Background: Distal embolization due to microthrombus fragments formed during predilation ballooning is considered one of the possible mechanisms of slow flow/no-reflow (SF/NR). Therefore, this study aimed to compare the incidence of intraprocedure SF/NR during the primary percutaneous coronary intervention (PCI) in patients with high thrombus burden (≥4 grade) with and without predilation ballooning for culprit lesion preparation. Methodology. This prospective descriptive cross-sectional study included patients with a high thrombus burden (≥4 grades) who underwent primary PCI. Propensity-matched cohorts of patients with and without predilation ballooning in a 1 : 1 ratio were compared for the incidence of intraprocedure SF/NR. Results: A total of 765 patients with high thrombus burden undergoing primary PCI were included in this study. The mean age was 55.75 ± 11.54 years, and 78.6% (601) were males. Predilation ballooning was conducted in 346 (45.2%) patients. The incidence of intraprocedure SF/NR was significantly higher (41.3% vs. 27.4%; p < 0.001) in patients with predilation ballooning than in those without preballooning, respectively. The incidence of intraprocedure SF/NR also remained significantly higher for the predilation ballooning cohort with an incidence rate of 41.3% as against 30.1% (p=0.002) for the propensity-matched cohort of patients without predilation ballooning with a relative risk of 1.64 (95% CI: 1.20 to 2.24). Moreover, the in-hospital mortality rate remained higher but insignificant, among patients with and without predilation ballooning (8.1% vs. 4.9%; p=0.090). Conclusion: In conclusion, predilation ballooning can be associated with an increased risk of incidence of intraprocedure SF/NR during primary PCI in patients with high thrombus burden.

Factors affecting delay in diagnosis of colorectal cancer: A cross-sectional study from a tertiary care hospital of Karachi, Pakistan.

BACKGROUND: Colorectal cancer (CRC) incidence is increasing in our region. There is no specific CRC control programme or national cancer registry in Pakistan. Previously, no data have been published on presentation delay and diagnosis delay of CRC in our region. This study is conducted to determine the factors affecting delay in presentation and diagnosis and to provide baseline information to launch a CRC control programme. The primary objective is to determine factors causing delay in diagnosis of CRC. The secondary objective is to evaluate the relationship between tumour site and stage of CRC with presenting symptoms and symptom duration. METHODS: This project is a prospective cross-sectional study on 113 biopsy-proven CRC patients admitted to the surgical ward of Civil Hospital Karachi. RESULTS: The total number of participants was 113. Presentation delay was observed in 83.2% of patients. The main reasons for a reported delay in the presentation were lack of patients' knowledge that these symptoms may be cancer (60.4%), the wrong diagnosis by the primary physician (34.6%) or the patient did not want to visit the doctor (0.04%). Most tumours (95%) originated from the sigmoid and rectum; 44.2% and 38.9% of the patients were diagnosed at Stages 3 and 4, respectively. CONCLUSIONS: This study revealed that CRC patients in Pakistan are facing delays in presentation and diagnosis. This is the reason behind diagnosis at the advanced stage with a poor prognosis. On the basis of this study findings, CRC control programme should be introduced to detect CRC at an early stage.

Benign to Malignant, Malignant to Metastatic: Phyllodes Tumor Biology Transformation.

Phyllodes tumors (PTs) of the breast are rare fibroepithelial neoplasms, typically characterized by their benign nature. We present a unique case of a 29-year-old Pakistani female who initially presented with a benign PT in her left breast. Despite undergoing multiple surgical resections over the course of a decade, the tumor exhibited a remarkable transformation in biology, progressing from a benign phenotype to malignancy. Subsequent recurrences manifested with increasing aggressiveness, ultimately culminating in distant metastasis to the bones, axillary nodes, chest wall, and abdominal wall. This case underscores the unpredictable nature of PTs and highlights the challenges in managing recurrent cases with malignant transformation. The clinical course described herein emphasizes the importance of vigilant monitoring and individualized treatment strategies in such cases.

Gender disparities in gastroenterology and hepatology conferences: The journey towards equality.

BACKGROUND: This study scrutinizes gender representation in invited faculty and conference committee leadership at key gastroenterology and hepatology conferences in Pakistan over five years, exploring the impact of the "glass ceiling" and "sticky floor" phenomena on gender diversity within academic medicine. METHODS: This cross-sectional study was conducted between January and March of 2023. The three major national societies of gastroenterology and hepatology in Pakistan that had been established for more than 10 years and the scientific programs of their annual conferences, which were publicly accessible, were included and coded as Society 1, Society 2 and Society 3 to maintain anonymity. The scientific programs for the last five years (2018-2022) were retrieved. The roles of invited faculties were identified as invited speakers, moderators, chairs/panelists, presidents and chairs of organizing or scientific committees and the gender makeup of the faculty was compared. Regression analysis was used to evaluate the trends for female representation over time for each role. RESULTS: Significant gender disparity was evident by an extremely lower cumulative proportion of female invited faculty compared to males (211 [11.9%] vs. 1567 [88.1%], p 0.001). The predominance of invited male faculty was observed across all societies as well as in various roles of invited faculty (p 0.01). A significant disparity has also been observed in leadership positions of all three societies (43 [95.5%] males vs. 2 [4.5%] females, p 0.001), while the trend of women's underrepresentation across all societies remained almost unchanged over time (slope = 0.08, R2 = - 0.078, p-value = 0.875). CONCLUSION: Our study unveils striking gender disparities in women's representation as invited speakers and other roles at the annual scientific conferences of major gastroenterology and hepatology. Additionally, male dominance remains entrenched, notably in leadership positions, necessitating a proactive, multifaceted approach to rectify gender inequities.

Evaluation of Open Rives-Stoppa and Lichtenstein Repair Methods for Bilateral Inguinal Hernias: A Single-Centre Comparative Analysis.

Aim The purpose of the study is to compare the two common open surgical methods for bilateral inguinal hernias: bilateral Lichtenstein repair and Rives-Stoppa repair. It evaluates their benefits, drawbacks, and outcomes to improve the management of bilateral inguinal hernias and enhance patient care and results. Background Abdominal wall hernias are prevalent in the surgical field, and they occur when intra-abdominal organs protrude through weakened or torn regions in the abdominal wall. The Lichtenstein repair, also known as the tension-free mesh repair, is one of the most widely used techniques that involves placing a synthetic mesh over the hernia defect to reinforce the abdominal wall. The Rives-Stoppa technique takes the posterior approach, which involves placing a large mesh in the preperitoneal space, which provides broad coverage of the potential hernia sites. Method This retrospective study included 86 male patients from the Department of General Surgery at Indus Health Network, Karachi, Pakistan. Data were collected up to three months post-operation for all open bilateral inguinal hernia repairs performed between January 2017 and April 2021. The patients were divided into two groups: group A underwent Lichtenstein repair, while group B underwent Rives-Stoppa repair. The procedures were performed by different surgeons and surgical trainees under direct supervision. Results Regarding post-operative complications (scrotal swelling, epididymo-orchitis, seroma formation, ipsilateral testicular swelling, surgical site infection, erectile dysfunction, wound dehiscence, fever, hydrocele, sensory abnormality, hernia recurrence in 3 months, post-operative pain in 14 days), there was no significant difference observed between the two groups. There were two recurrences within three months after Lichtenstein repair and one recurrence after Stoppa repair, but no statistical difference was demonstrated. Conclusion Statistically, both the Lichtenstein repair and the Rives-Stoppa repair demonstrated similar outcomes. However, the Rives-Stoppa repair offers distinct advantages for bilateral inguinal hernia repair, making it a preferable option in many cases as this approach utilises a single midline incision, simultaneously facilitating access to both hernial sites. This method ensures complete coverage of the myopectineal orifices bilaterally, addressing all potential hernia sites in the lower abdomen. These features collectively contribute to the technique's efficacy in managing bilateral hernias.

A Comparative Study Between Use of Topical Honey and Edinburgh University's Solution of Lime (EUSOL) Dressing in Necrotizing Fascitis Wounds.

Introduction Necrotizing soft tissue infection is potentially life-threatening and involves subcutaneous fascial planes, later involving overlying skin and, eventually, underlying muscles. Early diagnosis and prompt treatment are necessary for this disease's management to avoid significant morbidity and fatality. After resuscitation and optimization, early surgical debridement is followed by serials of dressing. Various materials like Edinburgh University's solution of lime (EUSOL), normal saline, povidone-iodine, and honey have been used as dressing solutions for necrotizing fasciitis. This study is based on comparing the effects of honey and EUSOL as dressing solutions in necrotizing fasciitis wounds. Methods A randomized clinical trial was conducted at the Civil Hospital Karachi, from March 2020 to July 2021. This study has been approved by the ethical review committee of the institution and registered at clinicaltrial.gov. Based on the dressing solution for necrotizing fasciitis, patients were divided into two groups, The honey group (intervention group) contains 90 patients, and the EUSOL group (control group) has 85 patients. Results A total of 175 patients' data were analyzed, 90 in the honey group and 85 in the EUSOL group. Patients presented to the hospital with symptoms of 6.20 ± 2.72 days in the honey group and 6.67 ± 4.08 days in the EUSOL group. The days required for clearance of slough in the honey group were 2.83 ± 0.79, while 2.48 ± 0.82 days in the EUSOL group with a p-value of 0.005. The duration of hospital stay was 4.96 ± 1.31 days in the intervention group and 9.33 ± 1.45 days in the control group, with a p-value of 0.007. Wound healing days were 20.23 ± 4.45 in the intervention group while 28.38 ± 7.06 days in the control group, with a significant p-value of 0.000. Conclusion While managing necrotizing soft tissue infection wounds with honey. Honey promotes faster wound healing and shorter hospital stays compared to EUSOL.

Diffuse St Depression With St Elevation Avr In Acute Coronary Syndrome And Its Association With Significant Left Main Or Three Vessel Coronary Artery Disease And Its Confounders.

BACKGROUND: : Global ST depression in 8 or more leads along with ST elevation in aVR has been considered as hallmark of widespread sub-endocardial ischemia. It has been associated with left main (LM) stem or three vessel disease (3VD). But different studies have shown different results. We collected data from patients to see association of these ECG changes with significant LM stem disease and/or significant (3VD). METHODS: TIt was a prospective observational study performed at tertiary care cardiac center. All patients with acute coronary syndrome (ACS) having global ST depression and ST Elevation in aVR (that is ST depression of at least 0.5 mv in ≥8 leads along with ST elevation in aVR of at least 0.5 mv) and have undergone coronary angiogram were included. RESULTS: Our study included 404 patients with above mentioned ECG findings. We observed significant LM stem or significant 3VD in 67% (n=274), 3VD in 55% (n=222) and significant LM stem in only 29% (n=118). Risk factors like diabetes, hypertension and smoking increase probability of these ECG changes up to 40.4%, 32.1% and 33.3% for significant LM stem disease and 62.7%, 57.1% and 57.5% for significant 3VD. Magnitude of ST elevation in aVR leads ≥1 mm increase sensitivity for LM stem disease 35% and for 3VD up to 60.4% and TIMI score ≥4 up to 36.7% for significant LM stem disease and 62.5% for significant 3VD. CONCLUSIONS: : Global ST depression along with ST elevation in aVR in patients with ACS has low probability for significant LM stem intermediate probability for significant 3VD. Factors like presence of diabetes, hypertension, smoking, magnitude of ST elevation in aVR, and TIMI score improves its diagnostic yield.

Comparative Efficacy and Safety Profiles of High-power, Short-duration and Low-power, Long-duration Radiofrequency Ablation in Atrial Fibrillation: A Systematic Review and Meta-analysis.

High-power, short-duration (HPSD) radiofrequency (RF) ablation is expected to be more effective and safer than low-power, long-duration (LPLD) RF ablation in treating atrial fibrillation (AF). Given the limited data available, the findings are controversial. This meta-analysis evaluated whether the clinical effects of HPSD outweigh those of LPLD. A systematic search of PubMed, Embase, and Google Scholar databases identified studies comparing HPSD to LPLD ablation. All the analyses used the random-effects model. This analysis included 21 studies with a total of 4,169 patients. Pooled analyses revealed that HPSD was associated with a lower recurrence of atrial tachyarrhythmias (ATAs) at 1 year (relative risk [RR], 0.62; 95% confidence interval [CI], 0.50-0.78; P = .00001; I2 = 0%). Furthermore, the HPSD approach reduced the risk of AF recurrence (RR, 0.64; 95% CI, 0.40-1.01; P = .06; I2 = 86%). The HPSD approach was associated with a lower risk of esophageal thermal injury (ETI) (RR, 0.78; 95% CI, 0.58-1.04; P = .09; I2 = 73%). The HPSD strategy increased first-pass pulmonary vein (PV) isolation (PVI) and decreased acute PV reconnection (PVR), both of which were predominantly manifested in bilateral and left PVs. HPSD facilitated a reduction in procedural time, number of lesions created during PVI, and fluoroscopy time. The HPSD method reduces ETI, PVR, and recurrent AF. The HPSD approach also reduced the procedural time, number of lesions created during PVI, fluoroscopy time, and post-ablation AF relapse in 1 year, improving patient outcomes and safety.

Comparative analysis of four established risk scores for prediction of in-hospital mortality in patients undergoing primary percutaneous coronary intervention.

OBJECTIVE: This study was conducted to compare the predictive power of Shock Index (SI), TIMI Risk Index (TRI), LASH Score, and ACEF Score for the prediction of in-hospital mortality in a contemporary cohort of ST-segment elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PCI) at a tertiary care cardiac center of a developing country. METHODS: Consecutive patients diagnosed with STEMI and undergoing primary PCI were included in this study. SI, TRI, LASH, and ACEF were computed and their predictive power was assessed as the area under the curve (AUC) on the receiver operating characteristics (ROC) curve analysis for in-hospital mortality. RESULTS: We included 977 patients, 780 (79.8%) of which were male, and the mean age was 55.6 ± 11.5 years. The in-hospital mortality rate was 4.3% (42). AUC for TRI was 0.669 (optimal cutoff: ≥17.5, sensitivity: 76.2%, specificity: 45.6%). AUC for SI was 0.595 (optimal cutoff: ≥0.9, sensitivity: 21.4%, specificity: 89.8%). AUC for LASH score was 0.745 (optimal cutoff: ≥0, sensitivity: 76.2%, specificity: 66.9%). AUC for the ACEF score was 0.786 (optimal cutoff: ≥1.66, sensitivity: 71.4%, specificity: 73.5%). CONCLUSION: In conclusion, ACEF showed sufficiently high predictive power with good sensitivity and specificity compared to other three scores. These simplified indices based on readily available hemodynamic parameters can be reliable alternatives to the computational complex scoring systems for the risk stratification of STEMI patients.

Left Ventricular Functional Remodeling after Primary Percutaneous Coronary Intervention.

Background: Improvement in left ventricular (LV) function after revascularization is an important determinant of long-term prognosis in a patient with acute myocardial infarction (AMI). However, data on the changes of LV function after revascularization are scarce in our population. Hence, this study was conducted to evaluate the changes in LV function and dimensions by echocardiography at 3 and 6 months after primary percutaneous coronary intervention (PCI). Materials and Methods: A total of 188 patients were recruited in this study who had undergone primary PCI. Patients with preexistent LV dysfunction, prior PCI, or with congenital heart disease were excluded. Echocardiography was performed at baseline (within 24 h of intervention), 3 months, and 6 months of intervention. Remodeling in terms of change in LV ejection fraction (LVEF), LV end-diastolic dimension (LVEDD), LV end-systolic dimension, and wall motion score index (WMSI) was evaluated. Results: Out of the 188 patients, 90.4% were male, and mean age was 53.94 ± 9.12 years. Baseline mean LVEF was 39.79 ± 6.2% with mean improvement of 5.11 ± 3.87 (P < 0.001) at 3 months and 6.38 ± 4.29 (P < 0.001) at 6 months. Baseline LVEDD was 46.23 ± 3.86 mm which improved to 44.68 ± 2.81 mm at 6 months. Basal WMSI decreased by -0.09 ± 0.08 and -0.13 ± 0.09 at 3 and 6 months, respectively, after revascularization. Conclusions: Primary PCI is the recommended mode of reperfusion in patients with AMI. It reduces infarct size, maintains microvascular integrity and preserves LV systolic function hence improving LV function.

Regression of coronary atherosclerosis through healthy lifestyle in coronary artery disease patients--Mount Abu Open Heart Trial.

AIMS: To evaluate the efficacy of a unique healthy and happy lifestyle (HLS) program in regression of coronary atherosclerosis and reduction in cardiac events in an open trial. METHODS: One hundred and twenty three angiographically documented moderate to severe coronary artery disease (CAD) patients were administered HLS comprising of low-fat, high-fiber vegetarian diet, moderate aerobic exercise and stress-management through Rajyoga meditation. Its most salient feature was training in self-responsibility (heal+thy) and self-empowerment through inner-self consciousness (swasth; swa=innerself, sth=consciousness) approach using Rajyoga meditation. Following a seven day in-house sojourn, patients were invited for six month follow-up for reassessment and advanced training. At the end of two years, all patients were asked to undergo repeat angiography. RESULTS: Three hundred and sixty coronary lesions were analysed by two independent angiographers. In CAD patients with most adherence, percent diameter stenosis regressed by 18.23 +/- 12.04 absolute percentage points. 91% patients showed a trend towards regression and 51.4% lesions regressed by more than 10 absolute percentage points. The cardiac events in coronary artery disease patients were: 11 in most adherence, and 38 in least adherence over a follow-up period of 6.48 yrs. (risk ratio; most vs least adherence: 4.32; 95% CI: 1.69-11.705; P < 0.002). CONCLUSION: Overall healthy changes in cardiovascular, metabolic and psychological parameters, decline in absolute percent diameter coronary stenosis and cardiac events in patients of CAD were closely related to HLS adherence. However, more than 50% adherence is essential to achieve a significant change.

Perception of Non-Alcoholic Fatty Liver Disease: Real-Life Experience From Pakistan.

Introduction Non-alcoholic fatty liver disease (NALFD) has become one of the most pervasive causes of hepatic pathology. Because of its marked association with metabolic syndrome, type II diabetes and cardiovascular disease, NAFLD has gained substantial focus recently. Its prevalence and incidence are on the rise in Pakistan. However, due to its indolent and mostly asymptomatic course, NAFLD is often overlooked. This reckless behavior towards a potentially deadly disease is influenced most notably by disinformation or flawed perception, although there are a number of other complex socioeconomic components to this as well. With respect to NAFLD, the gap between disease understanding and steps for management is growing in the Pakistani society. With this study, we hoped and aimed to evaluate just how far and wide these shortcomings were found and how was NAFLD perceived in the local populace via a self-administered survey. Methods This was a cross-sectional observational cohort study undertaken at the Department of Gastroenterology, Jinnah Postgraduate Medical Centre, and Medical Unit II, Dow University of Health Sciences, Ojha Campus, Karachi, Pakistan. All patients ≥18 years with a diagnosis of NAFLD were included in the study. NAFLD was diagnosed on the basis of sonographic evidence. All ultrasounds were done by a senior expert radiologist with at least 10 years of postgraduate experience. Ultrasounds were performed twice in all patients to rule out human error and bias. Perceptions regarding the knowledge of NAFLD were assessed using a self-administered survey questionnaire. Results The female-to-male ratio in our cohort was 3:1. The mean age and body mass index (BMI) recorded were 39.85 ± 9.79 years and 31.21 ± 3.6 kg/m2, respectively. Sixty participants (26.4%) knew about their disease (NAFLD) while only 36 (15.9%) knew what NAFLD was and only 33 (14.5%) participants knew about the cardiovascular risk associated with it. Nearly two-thirds of the patients considered themselves overweight, while 180 (79.3%) of them were willing to lose weight. However, just about half of the cohort admitted the need for improved eating habits and increased physical activity/exercise in their daily lives. Fifty-seven (25.1%) patients admitted to using alternative or quack medications and only 45 (19.8%) patients considered them harmful. Conclusions Patients harboring NAFLD have little to no knowledge about the disease and its nature or the fact that they are suffering from it despite being diagnosed clinically. Furthermore, while the general populace is willing to accept being overweight and having unhealthy eating habits, their willingness in initiating real-life practical steps to manage NAFLD is lacking.

Comparative analysis of four established risk scores for predicting contrast induced acute kidney injury after primary percutaneous coronary interventions.

OBJECTIVES:  This study aimed to compare Mehran Risk Score (MRS) with three well -known scoring systems namely CHA2DS2-VASc score, Canada Acute Coronary Syndrome Risk Score (C-ACS), and Thrombolysis in Myocardial Infarction risk index (TRI) to predict the contrast-induced acute kidney injury (CI-AKI) after primary percutaneous coronary intervention (PCI). BACKGROUND: CI-AKI is a common complication after primary PCI associated with an adverse prognosis. METHODS: In this study consecutive patients of primary PCI were included. Patients with chronic kidney diseases, exposure to the contrast medium within the past 7 days, and Killip class IV at presentation were excluded. MRS along with three risk scores namely CHA2DS2-VASc, C-ACS, and TRI were calculated for all patients and CI-AKI was defined as either 0.5 mg/dL or 25% relative increase in post-procedure serum creatinine. The area under the curve (AUC) curve was reported. RESULTS: Post primary PCI CI-AKI was observed in 63 (9.1%) patients out of 691 patients. The AUC was 0.745 [0.679-0.810] for MRS, 0.725 [0.662-0.788] for CHA2DS2-VASc, 0.671 [0.593-0.749] for C-ACS, and 0.734 [0.674-0.795] for TRI. Sensitivity and specificity were 61.9% [48.8-73.8%] and 76.0% [72.4-79.3%] for MRS ≥ 6.5, 66.7% [53.7-78.0%] and 66.7% [62.9-70.4%] for CHA2DS2-VASc ≥ 2, 52.4% [39.4-65.1%] and 79.9% [76.6-83.0%] for C-ACS ≥ 1, and 87.3% [76.5-94.4%] and 49.2% [45.2-53.2%] for TRI ≥ 16 respectively. CONCLUSIONS: The MRS has shown higher discriminating power than CHA2DS2-VASc, C-ACS, and TRI. However, the TRI can be of good value in clinical practice due to its simplicity and high sensitivity in detecting patients at higher risk of CI-AKI after primary PCI.

Retrorectal Epidermal Inclusion Cyst: An Incidental Finding During Cesarean Section.

An epidermal inclusion cyst is a benign lesion, frequently observed throughout the body. However, its presence in the retrorectal region is a rare occurrence. With a higher incidence in women and non-specific symptoms, these cysts are mostly an incidental finding. Here, we report a case of a 33-year-old female presenting with complaints of abdominal pain and sensation of incomplete and painful defecation. The patient's history revealed that a large pelvic cyst was found incidentally during her first cesarean section (CS) owing to an arrest in labor. A presumptive diagnosis of rectal duplication cyst was made based on digital rectal exam (DRE), computed tomography (CT), and magnetic resonance imaging (MRI) findings. For cyst removal, the patient underwent a midline laparotomy. A postoperative biopsy led to the confirmed diagnosis of the retrorectal epidermal inclusion cyst. On follow-up, our patient showed a smooth recovery without any complications. We conclude that when dealing with a pregnant woman with a pelvic mass, developmental cysts should always be kept in mind. Timely diagnosis and management of a retrorectal mass is essential for effective treatment and to prevent subsequent complications.

Jejunal Adenocarcinoma as a Rare Cause of Small Bowel Obstruction: A Case Report.

Jejunal adenocarcinoma, a small bowel adenocarcinoma (SBA), is a rare cause of small bowel obstruction. Jejunal adenocarcinoma classically presents with vague clinical symptoms, i.e., abdominal pain, discomfort, and weight loss, making timely diagnosis challenging. Owing to its diagnosis at a late stage, the prognosis of jejunal adenocarcinoma is poor. Curative resection of the tumor at the early stages remains a treatment of choice. Here, we report a case of a 55-year-old man presenting with symptoms of nausea, vomiting, abdominal pain, abdominal distension, and relative constipation. Computed tomography (CT) scan showed dilated small bowel loops. Exploratory laparotomy was performed, which revealed a jejunal stricture and dilated small bowel loops proximal to it. Suspicious stricture, along with the diseased portion of the intestine, was removed through en-bloc resection. Histopathology and metastatic workup revealed moderately differentiated adenocarcinoma with stage IIB (T4aN0M0). We conclude that, although rare, jejunal adenocarcinoma should be kept in mind when dealing with a patient presenting with symptoms indicating small bowel obstruction. Our purpose is to emphasize laparotomy as both a diagnostic and surgical modality for SBAs in early stages, especially in setups of low economic countries where advanced imaging techniques are relatively inaccessible.

Radial or femoral access in primary percutaneous coronary intervention (PCI): Does the choice matters?

BACKGROUND: This study was conducted with the aim of providing a quantitative appraisal of clinical outcomes of trans-radial access for primary percutaneous coronary interventions (PCI) in patients with ST-segment evaluation myocardial infarction (STEMI). METHODS: In this study, we compared two propensity-matched cohorts of patients who underwent primary PCI via trans-radial (TRA) and trans-femoral access (TFA) in a 1:1 ratio. The profile of two cohorts was matched for gender, age, and body mass index, diabetes, hypertension, family history, and smoking. The outcomes of primary PCI were compared for the two cohorts which included all-cause in-hospital mortality, heart failure, re-infarction, cardiogenic shock, bleeding, transfusion, cerebrovascular accident, and dialysis. RESULTS: This analysis was performed on a total of 2316 patients with 1158 patients each in the TRA and TFA group. We observed significantly lower rates of mortality, 0.8% (9) vs. 3.5% (41); p < 0.001 and bleeding, 0.5% (6) vs.1.6% (19); p = 0.009 with shorter hospital stay, 1.61 ± 1.39 vs. 1.98 ± 1.5 days, in trans-radial vs. trans-femoral. However, both fluoroscopic time and contrast volume were significantly higher in the TRA as compared to TFA group 15.57 ± 8.16 vs. 12.79 ± 7.82 min; p < 0.001 and 143.22 ± 45.33 vs. 133.78 ± 45.97; p < 0.001 respectively. CONCLUSIONS: Compared with TFA access, TRA for primary PCI is safe for patients with STEMI, it was found to be associated with a significant reduction in in-hospital mortality and bleeding complications.

Effects of Hatha yoga and Omkar meditation on cardiorespiratory performance, psychologic profile, and melatonin secretion.

OBJECTIVES: To evaluate effects of Hatha yoga and Omkar meditation on cardiorespiratory performance, psychologic profile, and melatonin secretion. SUBJECTS AND METHODS: Thirty healthy men in the age group of 25-35 years volunteered for the study. They were randomly divided in two groups of 15 each. Group 1 subjects served as controls and performed body flexibility exercises for 40 minutes and slow running for 20 minutes during morning hours and played games for 60 minutes during evening hours daily for 3 months. Group 2 subjects practiced selected yogic asanas (postures) for 45 minutes and pranayama for 15 minutes during the morning, whereas during the evening hours these subjects performed preparatory yogic postures for 15 minutes, pranayama for 15 minutes, and meditation for 30 minutes daily, for 3 months. Orthostatic tolerance, heart rate, blood pressure, respiratory rate, dynamic lung function (such as forced vital capacity, forced expiratory volume in 1 second, forced expiratory volume percentage, peak expiratory flow rate, and maximum voluntary ventilation), and psychologic profile were measured before and after 3 months of yogic practices. Serial blood samples were drawn at various time intervals to study effects of these yogic practices and Omkar meditation on melatonin levels. RESULTS: Yogic practices for 3 months resulted in an improvement in cardiorespiratory performance and psychologic profile. The plasma melatonin also showed an increase after three months of yogic practices. The systolic blood pressure, diastolic blood pressure, mean arterial pressure, and orthostatic tolerance did not show any significant correlation with plasma melatonin. However, the maximum night time melatonin levels in yoga group showed a significant correlation (r = 0.71, p < 0.05) with well-being score. CONCLUSION: These observations suggest that yogic practices can be used as psychophysiologic stimuli to increase endogenous secretion of melatonin, which, in turn, might be responsible for improved sense of well-being.
