ABSTRACT

Objectives: To compare the entrance skin doses (ESD) before and after implementation of a radiation safety policy in neonates (RSN), which focused on clinician-directed technical specifications on the digital X-ray machine. Methods: Prospective observations included two sets of X-rays: Before (BRSN) and after (ARSN) implementation of RSN (documented indication for Xray/expected posttest findings, settings of 40 kVp, 0.5 mAs, film-focus distance 100 cm, gonadal-shield, optimal collimation, and post-shoot image-enhancement). Results: 33 and 32 X-rays were analyzed in respective groups. Mean (SD) of calculated and machine-quantified ESD (µGy/m2) was higher in BRSN group as compared to ARSN group (P <0.001). All ARSN X-rays were interpretable for expected post-test findings. Conclusion: Clinicians’ cognizance of ability to make consequential bedside technical specifications, can reduce ESD without affecting interpretability. These single observations could have a larger impact in sick neonates, where multiple X-rays are done.

ABSTRACT

Objectives: To document the adverse cardiorespiratory events following first routine immunization in preterm neonates. Methods: We retrieved records of neonates with gestational age ?30 weeks, and included those who developed cardiorespiratory events after first vaccines before discharge. Our Unit’s protocol is to administer Bacillus Calmette-Guerin (BCG), hepatitis B vaccine to those discharged at <8 weeks postnatal age. Hexavalent, BCG, pneumococcal vaccine and rotavirus vaccines are given at 8 weeks of age, if hospital stay is predicted to be longer. Unit compliance to vaccination administration at appropriate ages were also measured. Results: Data of 161 neonates ?30 weeks (17.4% <27 week) who completed care in the unit was studied. Cardio-respiratory adverse events were reported in 21(13.7%). None of these required initiation of invasive ventilation. High flow nasal cannula therapy and caffeine restart were required for these events in 14 (9.3%) and 6 (3.9%) neonates, respectively. Lower gestational age, bronchopulmonary dysplasia and sepsis were significant risk factors on univariate analysis. On multivariate analysis, continued need for respiratory support at 4 weeks of age (P=aOR 14.5 (95% CI 5-59.1) was the only independent risk factor for post-vaccination cardiorespiratory adverse events. Of 38 who were not vaccinated at recommended ages by unit policy, 25 were missed opportunities, the rest were deemed unstable for vaccinations at that age by the clinical team. Conclusion: Adverse cardiorespiratory events were uncommon after first vaccinations in very preterm neonates. Administering vaccines in this group before discharge would allow monitoring for these events, especially for those who require long-term respiratory support.

ABSTRACT

Introduction: The present study was conducted to explore the awareness and perception of the coronavirus disease 2019 (COVID-19) vaccine among pregnant women. Material and Methods: A descriptive cross-sectional study was conducted from September 01, 2021, to September 28, 2021, among 301 pregnant women aged 18–35 years at antenatal care outpatient department in a tertiary care hospital of Western Maharashtra. Results: On assessing the knowledge and awareness score, the mean score (± standard deviation) was 7.83 ± 1.2 out of 16. A total of 176 (58.5%) had good scores(?8). There was no statistically significant association between knowledge and awareness scores and the level of education, type of residence, and age or with weeks of gestation. Although the overall awareness of study participants was satisfactory, 177 (58.8%) felt that COVID-19 vaccines should be avoided during the first trimester. Interestingly, 45 (15.3%) felt that vaccines should not be given during menstruation. There were misconceptions about perceived contraindication, with 81(26.9%), 50(16.6%) and 43(14.4%) responding that diabetes, hypertension and heart disease are contradicts respectively. Interestingly, a total of 52 (17.3%) responded as likely when enquired whether the present vaccine can cause infertility. Similarly, about 62% of study participants felt that the vaccine might alter the DNA. Conclusion: The present study revealed good overall knowledge and awareness about the COVID-19 vaccine among pregnant with certain misconceptions. The findings suggest that immediate health education programs, risk communication, and correct information should be disseminated by respective health authorities.

ABSTRACT

Background: Low cardiac output is a common complication following cardiac surgery and it is associated with higher mortality in the pediatric population. A gold standard method for cardiac output (CO) monitoring in the pediatric population is lacking. The present study was conducted to validate cardiac output and cardiac index measured by transthoracic echocardiography and Pressure recording analytical method, a continuous pulse contour method, MostCare Up in postoperative pediatric cardiac surgical patients. Materials and Methods: This was a prospective observational clinical study conducted at a tertiary care hospital. A total of 23 pediatric patients weighed between 2 and 20 kg who had undergone elective cardiac surgery were included in the study. Results: Spearman抯 correlation coefficient of CO between transthoracic echocardiography (TTE) and Pressure Recording Analytical Method (PRAM) showed of positive correlation (r = 0.69, 95% Confidence interval 0.59?0.77, P < 0.0001) Linear regression equations for CO between TTE and PRAM were y = 0.55 + 0.88x (R2 = 0.46, P < 0.0001). (y = PRAM, x = TTE), respectively. Bland? Altman plot for CO between TTE and PRAM showed a bias of ?0.397 with limits of the agreement being ?2.01 to 1.22. Polar plot analysis showed an angular bias of 6.55� with radial limits of the agreement being ?21.46 to 34.58 for CO and angular bias of 6.22� with radial limits of the agreement being ?22.4 to 34.84 for CI. Conclusion: PRAM has shown good trending ability for cardiac output. However, values measured by PRAM are not interchangeable with the values measured by transthoracic echocardiography.

ABSTRACT

Introduction: Pyogenic granuloma is a rather confusing reactive lesion of the oral mucosa, considering it is neither a bacterial infection nor does it produce any pus. In fact, even histologically, there is no formation of granulomas to substantiate the name. Intraoral actinomycosis is another interesting lesion due to its unique ability to masquerade itself as a swelling, abscess, or even a neoplasm. The occurrence of the two lesions separately is common in the oral cavity, however, their co-existence is extremely rare. Case Presentation: A 65-year-old female patient was referred from a private dental clinic with the chief complaint of a growth on her left posterior region of mouth, at the occlusal level of 15, 18 tooth regions for past 1 month. Conclusion: Clinicians should be aware about the occurrence of such rare combination of intraoral lesions, in order to make an accurate diagnosis and in turn, tailor a correct treatment protocol for these patients.

ABSTRACT

Background & objectives: The risk factors for clinically significant diffuse parenchymal lung abnormalities (CS-DPLA) persisting after severe coronavirus disease 2019 (COVID-19) pneumonia remain unclear. The present study was conducted to assess whether COVID-19 severity and other parameters are associated with CS-DPLA. Methods: The study participants included patients who recovered after acute severe COVID-19 and presented with CS-DPLA at two or six month follow up and control group (without CS-DPLA). Adults volunteers without any acute illness, chronic respiratory illness and without a history of severe COVID-19 were included as healthy controls for the biomarker study. The CS-DPLA was identified as a multidimensional entity involving clinical, radiological and physiological pulmonary abnormalities. The primary exposure was the neutrophil-lymphocyte ratio (NLR). Recorded confounders included age, sex, peak lactate dehydrogenase (LDH), advanced respiratory support (ARS), length of hospital stay (LOS) and others; associations were analyzed using logistic regression. The baseline serum levels of surfactant protein D, cancer antigen 15-3 and transforming growth factor-? (TGF-?) were also compared among cases, controls and healthy volunteers. Results: We identified 91/160 (56.9%) and 42/144 (29.2%) participants with CS-DPLA at two and six months, respectively. Univariate analyses revealed associations of NLR, peak LDH, ARS and LOS with CS-DPLA at two months and of NLR and LOS at six months. The NLR was not independently associated with CS-DPLA at either visit. Only LOS independently predicted CS-DPLA at two months [adjusted odds ratios (aOR) (95% confidence interval [CI]), 1.16 (1.07-1.25); P<0.001] and six months [aOR (95% CI) and 1.07 (1.01-1.12); P=0.01]. Participants with CS-DPLA at six months had higher baseline serum TGF-? levels than healthy volunteers. Interpretation and conclusions: Longer hospital stay was observed to be the only independent predictor of CS-DPLA six months after severe COVID-19. Serum TGF-? should be evaluated further as a biomarker.

ABSTRACT

Background & objectives: Due to lack of appropriate statistical knowledge, published research articles contain various errors related to the design, analysis and interpretation of results in the area of biomedical research. If research contains statistical error, however, costly, it may be of no use and the purpose of the investigation gets defeated. Many biomedical research articles published in different peer reviewed journals may retain several statistical errors and flaws in them. This study aimed to examine the trend and status of application of statistics in biomedical research articles. Study design, sample size estimation and statistical measures are crucial components of a study. These points were evaluated in published original research articles to understand the use or misuse of statistical tools. Methods: Three hundred original research articles from the latest issues of selected 37 journals were reviewed. These journals were from the five internationally recognized publication groups (CLINICAL KEY, BMJ Group, WILEY, CAMBRIDGE and OXFORD) accessible through the online library of SGPGI, Lucknow, India. Results: Among articles assessed under present investigation, 85.3 per cent (n=256) were observational, and 14.7 per cent (n=44) were interventional studies. In 93 per cent (n=279) of research articles, sample size estimation was not reproducible. The simple random sampling was encountered rarely in biomedical studies even though none of the articles was adjusted by design effect and, only five articles had used randomized test. The testing of assumption of normality was mentioned in only four studies before applying parametric tests. Interpretation & conclusions: In order to present biomedical research results with reliable and precise estimates based on data, the role of engaging statistical experts need to be appreciated. Journals must have standard rules for reporting study design, sample size and data analysis tools. Careful attention is needed while applying any statistical procedure as, it will not only help readers to trust in the published articles, but also rely on the inferences the published articles draw.

ABSTRACT

Adverse cardiac remodeling refers to progressive structural and functional modifications in the heart because of increased wall stress in the myocardium, loss of viable myocardium, and neurohormonal stimulation. The guideline-directed medical therapy for Heart failure (HF) includes Angiotensin receptor-neprilysin inhibitor (ARNI) (sacubitril/valsartan), ?-blockers, sodium-glucose co-transporter 2 (SGLT2) inhibitors, and mineralocorticoid receptor antagonists (MRA). ARNI is under-prescribed in India despite its attractive safety and efficacy profile. Therefore, the consensus discusses objectives and topics related to ARNI in the management of cardiac remodeling, and experts shared their views on the early timely intervention of effective dosage of ARNI to improve the diagnosis and enhance mortality and morbidity benefits in cardiac reverse remodeling (CRR).

ABSTRACT

Purpose: To analyze the correlation between the mean retinal nerve fiber layer (RNFL) and ganglion cell layer (GCL) thickness with axial length and refractive errors among children aged 5–15 years. Methods: This cross?sectional, observational study was done on 130 eyes of 65 consecutive subjects with refractive errors. The patients were evaluated for RNFL thickness and macular GCL thickness using spectral domain? optical coherence tomography. Results: One hundred and thirty eyes of 65 subjects aged between 5 and 15 years were divided into three groups based on their spherical equivalent in diopters (D). The children with a spherical equivalent of ??0.50 D were considered myopic, ??0.5 to ?+0.5 D were considered emmetropic, and ?+0.50 D were considered hypermetropic. RNFL thickness and GCL thickness were correlated with age, gender, spherical equivalent, and axial length. The mean global RNFL thickness was 104.58 ?m ± 7.567. Conclusion: There exists a negative correlation between RNFL thickness and macular GCL thickness with increasing severity of myopia and increase in axial length, and the possible reason could be stretching of the sclera, which further leads to stretching of the retina, resulting in thinner RNFL and macular GCL thickness

ABSTRACT

Iron deficiency (ID) with or without anemia is frequently observed in patients with heart failure (HF). Uncorrected ID is associated with higher hospitalization and mortality in patients with acute HF (AHF) and chronic HF (CHF). Hence, in addition to chronic renal insufficiency, anemia, and diabetes, ID appears as a novel comorbidity and a treatment target of CHF. Intravenous (IV) ferric carboxymaltose (FCM) reduces the hospitalization risk due to HF worsening and improves functional capacity and quality of life (QOL) in HF patients. The current consensus document provides criteria, an expert opinion on the diagnosis of ID in HF, patient profiles for IV FCM, and correct administration and monitoring of such patients.

ABSTRACT

Background: In acute chemical injury, damage can range from ocular surface epithelial defects to limbal and scleral ischemia. This may subsequently progress to corneal or scleral melting and perforation and finally result in phthisis bulbi. Thus, acute chemical injury is a potentially blinding condition and warrants attention. The accurate technique to assess the damage incurred should be practiced to avoid undertreatment and subsequent complications. Surgical intervention wherever needed should be appropriately timed and should be performed. The primary aim of medical or surgical intervention in acute chemical injury is to attain a stable and epithelized ocular surface. Even a conjunctival phenotype over the cornea is a desirable outcome. Purpose: This video discusses the nuances involved in the assessment and planning of Tenon advancement with amniotic membrane grafting for treating limbal ischemia in acute chemical injury. Synopsis: The video demonstrates the technique of restoration of limbal vascularization by performing Tenon advancement with amniotic membrane grafting and its outcome. Highlights: Ocular surface painting with fluorescein dye is essential to assess the areas of surface involvement. Merely instilling the fluorescein dye in the cul?de?sac will underestimate the extent of the damage. Tenon advancement should ideally be planned between 7 and 10 days following an injury when actual limbal blanching is obvious. A stable and epithelized ocular surface is the desirable outcome irrespective of the epithelial phenotype.

ABSTRACT

Background: Steven–Johnson syndrome (SJS) is a serious disorder affecting the skin and mucous membrane, causing multiple flaccid bullae and purpuric rashes with sheet?likeepithelial detachment including the ocular surface. The long?term outcomes following SJS are dismal and manifest as corneal vascularization, lid?wiper keratopathy, and severe dry eyes. The disease course can be modified if amniotic membrane graft is performed at the first week of disease, and the above?said complications can be avoided. This procedure thus not only decreases the morbidity but also improves the quality of life. Purpose: This video discusses the long?term sequelae of SJS which can be modified with timely intervention during the acute stage and thus significantly decreases morbidity. Synopsis: The video demonstrates the simple technique of amniotic membrane transplantation in the acute stage in SJS and its impact in long run. Highlights: There should be a low threshold for doing early amniotic membrane transplantation in patients with SJS with ocular surface involvement. Early intervention can change the disease course and decrease disease morbidity significantly.

ABSTRACT

SUMMARY: Traditional methods of bone retrieval from embalmed cadaver are not able to meet the demand of medical colleges as they are time consuming & tedious, thus there is need of evaluating an alternative approach that includes use of laundry detergent. The purpose of the study was to compare & establish the most effective method between laundry detergent and 10 % antiformin solution methods to procure clean bones. Thirty-two bones of the right side that were included in the inclusion criteria obtained from the four embalmed cadaver were cleaned by laundry detergent and of the left side by 10 % antiformin solution methods. Retrieved clean bones were evaluated for their cleanness using the scale from 0 to 5. The mean cleanness scores of the bones cleaned by laundry detergent method were not significantly different at 95 % confidence interval than the mean cleanness scores of the bones cleaned by 10 % antiformin solution method. The study found that though there is no significant difference in the mean cleanness score of the bones cleaned by two employed methods nevertheless, bones were found to be cleaner by using 10 % antiformin solution method and bones obtained by using laundry detergent method had smooth surface as well as more suitable for flat bones.


Los métodos tradicionales de recuperación de huesos de cadáveres embalsamados no pueden satisfacer la demanda de las facultades de medicina, ya que consumen mucho tiempo y son tediosos de realizar, por tanto es necesario evaluar un enfoque alternativo que incluya el uso de detergente de lavandería. El propósito del estudio fue comparar y establecer el método más eficaz entre el detergente para la ropa y los métodos de solución de antiformina al 10 % para obtener huesos limpios. Fueron utilizados 32 huesos del lado derecho que se incluyeron en los criterios de inclusión obtenidos de los cuatro cadáveres embalsamados. Los huesos se trataron con detergente de lavandería y los del lado izquierdo con métodos de solución de antiformina al 10 %. Los huesos tratados se evaluaron respecto a su limpieza utilizando una escala de 0 a 5. Las puntuaciones media de limpieza de los huesos tratados con el método de detergente no fueron significativamente diferentes en un intervalo de confianza del 95 % de las puntuaciones medias obtenidas respecto a la limpieza de los huesos tratados con antiformina al 10 %. El estudio determinó que, aunque no hay hubo diferencia significativa en la puntuación media de la limpieza de los huesos tratados por los dos métodos, se observó que utilizando el método de solución de antiformina al 10 %, la limpieza de los huesos era mejor, sin embargo, los huesos planos presentaban una superficie más lisa cuando se usó el método de detergente de lavandería.

ABSTRACT

Background: Metabolic bone disease (MBD) is a morbidity of multifactorial etiology with a high incidence in very preterm infants. We planned to study the incidence of MBD after implementation of bone health focussed nutritional strategy (BNS) in those <30 weeks gestation at birth. Methods: This prospective cohort study including preterm newborns (<30 weeks) who received nutrition that incorporated (a) Early initiation of intravenous potassium phosphate; (b) Early enteral supplementation with multicomponent human milk fortifier at enteral feed tolerance of 40 mL/kg/day feeds itself; and (c) Weekly phosphorus measurements with optimization of enteral intakes. Incidence of MBD at 4 weeks of postnatal age and beyond were analyzed. Other relevant safety and clinical outcomes were measured. Results: Of the 67 included neonates receiving BNS, 20.9% were classified as MBD. There was a low rate of hyperphosphatemia (4.5%) and hyperkalemia (2.9%). Full enteral feeds were achieved by median (IQR) of 6 (5,7) postnatal days. Conclusion: In preterm newborns (24-30 weeks) MBD incidence was 20.9% after BNS was implemented. Intravenous potassium salt of phosphorus and early use of HMF were safe and feasible.

ABSTRACT

Purpose: To assess the change in the amount of astigmatism caused by frown, straight, and smile incision in patients with pre?existing against?the?rule (ATR) astigmatism of more than and equal to 1 diopter Methods: This is a prospective, comparative study conducted over 18 months on 60 patients. Twenty patients were allocated to each incision using simple random sampling. Demographic details, best?corrected visual acuity (BCVA), intraocular pressure (IOP), anterior and posterior segment evaluation, and A?scan were done. An average of three measurements of K horizontal (Khavg), K vertical (Kvavg), and difference between the two (Khavg ? Kvavg) were taken using manual keratometry. All surgeries were performed by a single surgeon. All the data analyses were performed by using IBM Statistical Package for the Social Sciences (SPSS) version 20 software. Frequency distribution and cross tabulation were performed to prepare the tables. Results: In frown incision, Khavg ? Kvavg was significantly decreased on day 45 from the preoperative value (P < 0.001), followed by straight incision (P < 0.001), and smile incision (P < 0.001). Maximum decrease was observed in frown incision (49.15%) followed by straight (37.75%) and smile (28.57%) incisions. Conclusion: Our results are consistent with reduction of pre?existing ATR astigmatism with temporal incisions, and frown incision seems to be the best approach.

ABSTRACT

An Online Survey among Interventional Cardiologists (IC) assessed the knowledge (five questions) and practice of radiation safety (eleven questions). Out of 185 respondents, knowledge of annual radiation dose (2% knew), LAO cranial view giving maximum radiation (48%) and benefit of assessment of radiation exposure with dose area product (31%) was limited. Radiation safety was practiced “whenever I remember” in 37e59%. Radiation safety practices were optimal frame rate selection (32%), distancing from x-ray unit (17%), collimation use (30%), positioning the image detector close to chest (91%) and personal dosimeters use (40%). A major gap exists between knowledge and practice of radiation safety

ABSTRACT

Background: Cryptogenic strokes are common in young adults. Patent foramen ovale (PFO) is an important cause of cryptogenic ischemic strokes. Transcranial Doppler (TCD) with bubble contrast is a noninvasive bedside tool in screening for PFO and other right to left shunt (R-L shunt). Percutaneous PFO closure in selected patients with a high risk for paradoxical emboli is beneficial. Data on PFO in young cryptogenic strokes from India are limited. Aims: To determine the utility of screening for R-L shunt using TCD in young patients with cryptogenic strokes and to identify clinical predictors of an R-L shunt. Materials and methods: This was a hospital-based prospective study conducted between January 2013 and December 2019 in a tertiary hospital in South India. All consecutive patients with ischemic stroke and ages between 18 and 45 years were included. TCD with bubble contrast study was performed on all patients. Those who were TCD bubble contrast study positive and had features of an embolic stroke of undetermined source (ESUS) underwent transesophageal echocardiography (TEE) to confirm a PFO and to look for its high-risk features. Selected ESUS patients with PFO and associated high-risk features as identified on TEE underwent percutaneous PFO device closure. All patients were followed up in the stroke and cardiology clinics. Results: During the study period, 6,197 patients with ischemic strokes were screened for eligibility of which 304 (4.9%) were between the age of 18 and 45 years. Of these, 300 patients with ischemic stroke in young underwent the TCD bubble contrast study. R-L shunt was found in 121 (40.3%) patients. Based on an extensive etiological evaluation, 72 patients were identified to have an ESUS and underwent TEE for confirming PFO. Of these, 65 patients had PFO, four were negative, and three were found to have extracardiac shunts. Based on clinical findings, imaging features, and high-risk features on TEE, 29 patients underwent PFO closure. Activity at the time of stroke onset equivalent to a Valsalva maneuver (p ? 0.01), isolated cortical infarction (p = 0.027), and posterior circulation involvement (p = 0.0135) were significantly associated with the presence of an R-L shunt. The patients who had a higher modified anatomical-functional risk of paradoxical embolism (AF-RoPE) score, a high-grade shunt on the TCD bubble contrast study had a longer length of the tunnel and had the presence of an interatrial septal aneurysm (p = 0.012) were referred for PFO device closure. Conclusions: R-L shunt is common in cryptogenic ischemic strokes in young. TCD with bubble contrast study is a noninvasive and feasible bedside tool to detect them. Applying the ESUS criteria in these cryptogenic strokes with a positive TCD bubble contrast study can be then used for selecting patients for more invasive tests like TEE. High-risk PFOs picked up with TEE can be then considered for PFO closure for secondary stroke prevention. The history of Valsalva maneuver-like activity (such as lifting heavy weights or straining) at the time of stroke onset can be a clinical predictor for the presence of an R-L shunt. In addition to isolated cortical infarction, the presence of posterior circulation infarct in ESUS can predict the presence of an R-L shunt.
