An echocardiographic evaluation to determine the immediate and short-term changes in biventricular systolic and diastolic functions after PDA device closure-an observational analytical prospective study (echo- PDA study). Indian Heart J 2021; 73:617-621. [PMID: 34627579 PMCID: PMC8551535 DOI: 10.1016/j.ihj.2021.06.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2020] [Revised: 06/03/2021] [Accepted: 06/27/2021] [Indexed: 11/25/2022] Open
Abstract
Objectives –This prospective study with a sizable cohort was undertaken to assess changes in left and right ventricle systolic and diastolic functions after percutaneous patent ductus arteriosus device closure with appropriate follow up evaluation. Methods – It is an observational analytical prospective study. Ninety-eight patients were recruited out of which sixty-eight patients underwent percutaneous PDA device closure and were taken for final analysis. The primary objective was to study the left and right ventricular systolic and diastolic functions pre- and post-procedure at 48 h with follow up analysis at six months. Results – The mean age of the patients was 7.88 ± 5.05 years with the female to male ratio was 3.85:1. Thirty-three (48.52%) of the patients had immediate post PDA device closure LV systolic dysfunction. It was more common in those having pre-procedure mean low LVEF and those having a significant reduction in mitral A velocity. It became normal at six months follow up. The study reported immediate decrease in mea/n LVEF from 63.55 ± 8.11% to 48.19 ± 7.9%. The changes in LVEDD, LVEF, LVFS and LVEDV were statistically significant (p < 0.0001). In diastolic functions, there were significant reductions in peak early and late diastolic velocities. There was no statistically significant difference in right chamber functional assessment. Conclusion Asymptomatic LV systolic and diastolic dysfunction in immediate post PDA closure period is a common complication and reported in around 48.5% cases. It was more common in those having pre-procedure mean low LVEF and those having a significant reduction in mitral A velocity.

Abstract
Objectives Though invasive monitoring is the most accurate to estimate diastolic dysfunction but it has its own risk. The purpose of this study was to find out any standardized correlation between invasive and non -invasive parameters. Methods It is an observational, descriptive study comprising of a total of 500 patients. The primary objective of the study was to determine the correlation between echocardiographic diastolic parameters and invasively measured left ventricular end diastolic pressure (LVEDP). Results On studying correlation of different invasive and non-invasive data it was reported that there was a weak correlation between peak E velocity (r = 0.14, p = 0.631), Peak A velocity (r = 0.67, p = 0.59), IVRT (r = −0.35, p = 0.178), Mitral deceleration time (DT) (r = −0.06, p = 0.842), pulmonary venous peak systolic (r = −0.02, p = 0.966) and diastolic flows (r = 0.47, p = 0.201) to LVEDP. There was a good positive correlation between elevated LVEDP and difference in duration of pulmonary venous and mitral flow at atrial contraction (A-Ard) and E/Ea at all four longitudinal segments of the left ventricle. The sensitivity and specificity for detecting an elevated LVEDP of more than 12 mm Hg, using a cut off value of E/Ea< 8, were 89% and 90%.Lateral E/Ea ≥ 12, LAVI ≥34 mL/m2, and Ard–Ad > 30 msec have the greatest diagnostic value for diagnosing diastolic dysfunction in HFpEF patients. Conclusion Lateral E/Ea ≥ 12, LAVI ≥34 mL/m2, and Ard–Ad > 30 msec have the greatest diagnostic value for diagnosing diastolic dysfunction in HFpEF patients and have good correlation with invasively measured LVEDP.

Abstract
Our retrospective cohort study assesses the survival probability and identifies the demographic and clinical predictors of mortality in HIV patients taking antiretroviral therapy using an antiretroviral therapy centre data in Western India. Secondary data on 7532 registered HIV-infected individuals between September 2006 and January 2013 were analysed. The probability of survival at 75 months was 84.9%. Significant indicators of poor chances of survival were greater age, lower occupation class, lower CD4 count, poor functional status; higher stage of disease, lower weight, the presence and type of opportunistic infections, co-trimoxazole therapy and poor adherence to antiretroviral therapy. We thus find that, in addition to pre-ART, antiretroviral therapy clinical status and treatment adherence, socioeconomic status plays an important influence on ultimate survival of HIV patients on antiretroviral therapy.

Abstract
Assessing quality of life (QOL) outcome helps to show the effect of antiretroviral therapy (ART) on the subjective perception of its benefits among patients with HIV. A cross-sectional assessment of QOL, using the World Health Organization WHOQOL-HIV, on 204 HIV patients taking ART in western India showed patients with HIV on ART as having the best QOL score in the spiritual domain and the worst in the environment domain. Patients who are single, highly educated, of higher occupational status, with no HIV-positive children, not undergoing frequent hospital admissions, with access to a counsellor for support, who are not stigmatised or discriminated against due to HIV status, who do not have guilt or suicidal ideas, and who are theist, tend to have a better QOL, irrespective of their clinical condition or ART regimen. Patients' personal perceptions and feelings, societal support or stigma, and sociodemographic status have a more significant influence on QOL than clinical variables.

Abstract
Rheumatoid arthritis (RA) is a common chronic inflammatory autoimmune disorder which significantly impacts patients' lives and can lead to permanent disability. Inflammation in RA not only affects joints; but can affect organs including the heart and lungs. Early diagnosis, initiation of intensive drug therapy, and a multidisciplinary care approach have vastly improved the long-term prognosis for those living with the condition. However, RA patients often present with co-morbidities which add to the complexity of clinical management. Orofacial conditions associated with RA which dental professionals need to be aware of include periodontal disease, temporomandibular dysfunction and salivary gland dysfunction. In this article, we provide information on RA, oral health in RA and guidance on how best to manage patients with RA in general dental practice.

Abstract
OBJECTIVE The primary aim of the present study was to evaluate the complications, particularly conduction blocks, subsequent morbidity and mortality, and effect of thrombolytic therapy in Indian patients with inferior wall myocardial infarction (IWMI). METHODS This was a prospective, observational, single-center study conducted at LPS Institute of Cardiology, Kanpur, from December 2011 to May 2014. Patients who presented with typical chest pain and were subsequently diagnosed by standardized diagnostic criteria as having IWMI were enrolled. Patients were grouped on basis of conduction abnormalities, right ventricular (RV) infarction and thrombolytic treatment. Each group was analyzed for comparison of complication profile and mortality. RESULTS Of 573 patients with IWMI enrolled in the study (mean age: 58.90±12.3 years), 81.2% were male, 225 (39.3%) had conduction blocks, and 189 (32.9%) had RV infarction. In patients with conduction blocks, mortality occurred in 27 patients (12.0%) in contrast to 3.4% of patients without conduction block (p<0.03). Also, there were 27 cases of in-hospital mortality in patients with RV infarction compared with 9 cases in patients without RV infarction (p<0.01). Thrombolytic therapy significantly reduced mortality in patients with IWMI (p<0.001). A significant reduction was observed in cardiogenic shock (p=0.002), severe mitral regurgitation (p=0.007), and left ventricular failure (p<0.001) in patients undergoing thrombolytic therapy. CONCLUSION In Indian patients with IWMI, incidence of conduction blocks was higher than previously reported studies. Major complications such as atrioventricular block and RV infarction are associated with increased mortality and poor clinical outcomes. Thrombolytic therapy has a beneficial role in reduction of mortality rate and other complications.

Abstract
BACKGROUND The current study was planned to identify the epidemiological factors associated with leptospirosis in South Gujarat region using neighborhood controls. METHODS A total of 100 cases of leptospirosis occurred in South Gujarat region during the year 2012 were selected using simple random sampling. Three neighbors of the selected cases formed the controls (n = 300). A pretested structured questionnaire was used for data collection and data were analyzed using Epi Info 2007. RESULTS There was significant association of illiteracy (odds ratio [OR] =1.82, 95% confidence interval [CI] =1.14-2.89), working in waterlogged fields during the reference season (OR = 4.6, 95% CI = 1.6-17.9), swimming/bathing in canals, open air defecation practices, storage of cow dung in or surrounding house, residence in the house made up of cow dung walls, households with access of food to rodents, injuries over hands/foot during the endemic season (OR = 3, 95% CI = 1.8-4.8), and history of skin disease during the endemic season (OR = 4.2, 95% CI = 2-8.5), with leptospirosis. Only 10% of individuals had gumboots for protection. A total of 83 (83%) cases and 240 (80%) controls had taken oral doxycycline chemoprophylaxis (P > 0.05). Cases had taken chemoprophylaxis for a median 4 weeks (range: 1-8) while controls had taken the same for median 8 weeks (range = 1-8) (P < 0.002). CONCLUSIONS Although the commonly established factors appear to be associated with leptospirosis, the role of host factors seems to play a more important role in determining susceptibility to leptospirosis in exposed individuals.

Abstract
Objectives: Cosmetics are a multi-billion dollar industry today. The present study was designed with an objective to know the extent, purpose, type and awareness for cosmetic in people's daily life in Surat city. Materials & Methods: The study was conducted among 500 randomly selected people from the Surat city through convenience sampling. All the participants were interviewed personally, using structured questionnaire. The whole study was conducted from December, to March, 2008. Results; Around 73% of the population used cosmetics for protection purpose, while only 37% used it for attraction and 19% for fashion. Only 31% checked whether cosmetic they used were tested on animals or not. 89% of the people are concerned about the brands of the cosmetic and advertisement is an important source in the selection of the cosmetics. People still prefer ayurvedic products which comprise of 44% of the total population. Only 9% of the people use the expired products suggesting that people are aware that expired products cannot be used. 77% of the people are aware about the side effects of the cosmetics. Conclusion: Overall prevalence of cosmetic product use is increasing among both males and females. Though, associated increase in awareness regarding safe use of the same was not present widely. The use of other cosmetic services like skin specialist visits, contact lenses usage is also increasing slowly.

Abstract
Background: In recent time issues of career choices in medical student has been gaining mounting attention. Aim: The current study was planned with an aim to understand issues and dilemmas in career planning of medical students in Surat city, India Methods: This is a cross-sectional study comprising of personal interviews using a self -designed structured questionnaire among 400 simple randomly selected medical students, interns and junior residents of Surat Municipal Institute of Medical Education and Research covering issues associated with their career concerns and future life. Data analysis was done with help of Epi Info 7. The study sample comprised of students 46.5%, intern doctors 36%, junior resident doctors 17.5%. Results:Females were more content with either a graduate or a post graduate degree, whereas males were more inclined towards pursuing super specialty degrees (P<0.001). Majority 62% of the respondent stated that given another chance, they would again like to choose for medical studies only. The percentages of females interested in a non clinical career abroad as compared to clinical career in India were lower. Majority 89% of respondents agree that there is more struggle for the students who enter M.B.B.S. from a non medical background. Percentages of males in favor of increasing the postgraduate/super specialty seats far exceeded females (P<0.0001). The vast majority of the respondents wanted the specialty and super specialty seats to increase as they wanted an equal ratio of Undergraduate: Postgraduate seats (70%). Those who did not favor the increase in the seats perceived that the quality of treatment may actually worsen rather than improve if the number of seats increased (60%). Conclusion: Freshly graduating doctors do face a severe dilemma regarding their future career after graduation, which is a very perplexing situation for them and their parents, as there is absence of any career guidance cell; absence of the culture and avenues of campus placement; and there is human need to be materialistically comparable to their counterparts who are already in a job as an engineer.

Abstract
AIMS The aims of the study were to ascertain difference in lipid levels of 'Young' onset of coronary artery disease (CAD) (≤ 45 years) vs. 'Not so Young' onset of CAD (≥ 55 years) among north Indians and also to investigate determinants of 'dyslipidaemia' in CAD patients. METHODS This was a prospective, multicentric, randomised, observational study carried in eight centres of UP, India. All blood investigations were performed employing a central laboratory. RESULTS Out of a total 435 patients studied, 218 were in the 'young group' (YG) and 235 were in the 'Not so Young Group' (NSYG). Dyslipidaemia was more common in YG as evident by significantly higher levels of total cholesterol, triglycerides, low- and very low-density lipoprotein cholesterol as compared to NSYG. Diabetes, hypertension, urban lifestyle, and family history of CAD were found to be important determinants of dyslipidaemia in YG. CONCLUSION We conclude that lipid levels among north Indians are significantly higher in younger patients with CAD when compared with elderly.

Abstract
PURPOSE To report the magnitude and causes of unilateral absolute blindness (no light perception) and barriers faced by persons with unilateral blindness in the South Batinah region of Oman. METHODS Between January and June 2002, 12,000 patients were evaluated for visual acuity, ocular pressure, anterior ocular biomicroscopic examination, and posterior segment indirect ophthalmoscopy examination by ophthalmologists at Al Rustaq hospital in Oman. Patients having no perception of light in at least one eye were included in the cohort. A closed-ended questionnaire was used to collect data on the personal profile, history of blindness, barriers perceived as the cause of blindness, and participants' attitude towards eye care and quality of life following visual disability. RESULTS In the 12,000 patients studied, absolute unilateral blindness (no perception of light) was present in 122 persons, a rate of 1.0% in our series. The onset of blindness was gradual in 78 (63.9%) persons and 64 (54.9%) persons had unilateral blindness for more than 10 years. The main causes of blindness e phthisis/absent/disorganized blind eye, which was present in 64 (52.5%) persons; glaucoma, seen in 49 (40.2%) participants; and corneal opacity, seen in 8 (6.5%) persons. Eighty 4.8%) persons had <3/60 vision in the fellow eye. Thirty (24.6%) persons had cataract and 19 (15.6%) persons glaucoma in the fellow eye. Forty-eight (39.3%) persons had undergone cataract surgeries while 2 (1.6%) persons were operated for glaucoma in the fellow eye. Lack of access to ophthalmic services and use of traditional medicines during the onset of blindness were reported by nearly half of the cohort. The attitude towards blindness was negative in two thirds of subjects. CONCLUSIONS Cataract and glaucoma were important determinants of visual impairment in the fellow eyes of this cohort. These patients are at higher risk of developing bilateral impairment and need special care to prevent/treat visual disabilities in the fellow eyes. Using appropriate services, one can attempt attitudinal changes, rehabilitate them, and create a positive attitude towards life.
