Evaluating Clinical Reasoning in Undergraduate Medical Education: The Value of a Virtual Oral Assessment

BACKGROUND

Oral assessments are essential components of board certification in numerous fields, as they provide insight into problem-solving capacity and clinical reasoning. The development of clinical reasoning often begins in undergraduate medical education and remains a challenge to assess.

OBJECTIVE

We developed a pilot oral assessment to evaluate medical student oral presentations and systematically assess clinical reasoning. This was incorporated into a previously existing cumulative assessment at the conclusion of the third year of medical school, with the intent to demonstrate feasibility and future reliability of this exam format.

METHODS

This pilot oral assessment was developed using content taught during third year clerkships. A modified Assessment of Reasoning Tool (ART) was used as the evaluation metric. It was conducted virtually to include faculty members from multiple disciplines and accommodate schedules and space limitations.

RESULTS

A total of 152 third year medical students completed the exam, with a total of 15 faculty examiners. 89% of medical students scored as complete in hypothesis directed history, 93% in problem representation, 86% in prioritized differential diagnoses, and 67% in effectively directing management. Most examiners felt an oral assessment is effective to determine a medical student's clinical reasoning ability.

CONCLUSIONS

Virtual oral assessments of clinical reasoning can be incorporated in undergraduate medical education to identify students struggling with components of clinical reasoning, while also allowing maximum flexibility for the clinician educator workforce as examiners. Longitudinal use of these exams would be valuable to track the development of clinical reasoning across the medical school curriculum.

Dyslipidemia and heart failure: current evidence and perspectives of use of statins

Heart failure (HF) is a condition with growing morbidity and mortality. Dyslipidemia in HF is not concentrated around hypercholesterolemia as in coronary artery disease. As a corollary, the robust benefits seen with statins across the spectrum of CAD have not been replicated in HF. Multiple potential pleiotropic effects of statins include anti-inflammatory, antioxidant, endothelial stabilization, antiapoptotic, anti-thrombotic, and modulation of the autonomic system apart from lipid lowering. These benevolent actions need to be counterbalanced with the potential derangement of ubiquinone, selenoprotein and endotoxin pathways. While small randomized and non-randomized studies demonstrated a multitude of benefits in clinical and surrogate endpoints, two large RCTs failed to demonstrate unequivocal benefits. However, multiple large meta-analyses do demonstrate definite improvement in clinical endpoints including death and heart failure hospitalization. The clinical likelihood of benefit was higher in younger patients with less advanced HF and use of lipophilic statins.

Behaviour support in dentistry: A Delphi study to agree terminology in behaviour management

OBJECTIVES

Dental behaviour support (DBS) describes all specific techniques practiced to support patients in their experience of professional oral healthcare. DBS is roughly synonymous with behaviour management, which is an outdated concept. There is no agreed terminology to specify the techniques used to support patients who receive dental care. This lack of specificity may lead to imprecision in describing, understanding, teaching, evaluating and implementing behaviour support techniques in dentistry. Therefore, this e-Delphi study aimed to develop a list of agreed labels and descriptions of DBS techniques used in dentistry and sort them according to underlying principles of behaviour.

METHODS

Following a registered protocol, a modified e-Delphi study was applied over two rounds with a final consensus meeting. The threshold of consensus was set a priori at 75%. Agreed techniques were then categorized by four coders, according to behavioural learning theory, to sort techniques according to their mechanism of action.

RESULTS

The panel (n = 35) agreed on 42 DBS techniques from a total of 63 candidate labels and descriptions. Complete agreement was achieved regarding all labels and descriptions, while agreement was not achieved regarding distinctiveness for 17 techniques. In exploring underlying principles of learning, it became clear that multiple and differing principles may apply depending on the specific context and procedure in which the technique may be applied.

DISCUSSION

Experts agreed on what each DBS technique is, what label to use, and their description, but were less likely to agree on what distinguishes one technique from another. All techniques were describable but not comprehensively categorizable according to principles of learning. While objective consistency was not attained, greater clarity and consistency now exists. The resulting list of agreed terminology marks a significant foundation for future efforts towards understanding DBS techniques in research, education and clinical care.

Educational guidelines on sexual orientation, gender identity and expression, and sex characteristics biases in medical education

A commitment to diversity, equity, inclusion, and belonging in medical education requires addressing both explicit and implicit biases based on sexual orientation, gender identity and expression, and sex characteristics and the intersectionality with other identities. Heterosexism and heteronormative attitudes contribute to health and healthcare disparities for lesbian, gay, bisexual, transgender and queer or questioning, intersex, asexual individuals. Student, trainee, and faculty competencies in medical education curricula regarding the care of lesbian, gay, bisexual, transgender and queer or questioning, intersex, asexual patients and those who are gender nonconforming or born with differences of sex development allow for better understanding and belonging within the clinical learning environment of lesbian, gay, bisexual, transgender and queer/questioning, intersex, asexual learners and educators. The Association of Professors of Gynecology and Obstetrics issued a call to action to achieve a future free from racism and bias through inclusivity in obstetrics and gynecology education and healthcare, which led to the creation of the Association of Professors of Gynecology and Obstetrics Diversity, Equity, and Inclusion Guidelines Task Force. The task force initially addressed racism, racial- and ethnicity-based bias, and discrimination in medical education and additionally identified other groups that are subject to bias and discrimination, including sexual orientation, gender identity and expression, and sex characteristic identities, persons with disabilities, and individuals with various religious and spiritual practices. In this scholarly perspective, the authors expand on previously developed guidelines to address sexual orientation, gender identity and expression, and sex characteristics bias, heterosexism, and heteronormative attitudes in obstetrics and gynecology educational products, materials, and clinical learning environments to improve access and equitable care to vulnerable individuals of the lesbian, gay, bisexual, transgender and queer or questioning, intersex, asexual community.

Singapore dentists' attitudes toward dental care provision for older adults with disabilities

OBJECTIVES

This study aimed to assess dentists' attitudes toward providing dental care for older adults with disabilities in Singapore and the factors influencing their willingness to provide care.

BACKGROUND

Dentists face a rapidly ageing patient demographic. Practitioner unwillingness to circumvent the attending challenges of care provision prevents older adults from accessing the dental care necessary for better oral and systemic health. Previous studies have reported on dentists' attitudes toward caring for older adults with disabilities; however, these are mostly limited to dependent older adults and exclude frail, community-dwelling older persons.

METHODS

A cross-sectional study was conducted in 2020 using a self-administered questionnaire. Quantitative data analysis was presented in the form of descriptive statistics, followed by bivariate analyses.

RESULTS

There were 193 respondents, a response rate of under 9%. Dentists were less willing, confident and involved in the care of older adults with disabilities as the individual's severity of impairments increased. Less than half of respondents were willing to treat individuals with severe disabilities in cooperation (23.3%), swallowing (30.6%), mobility (33.7%) and communication (45.1%). Dentists with training in geriatric dentistry were more willing to provide care. However, younger dentists, general dental practitioners, private practitioners and public sector dentists had specific restraining and driving forces, which further modulated their willingness to provide care.

CONCLUSIONS

The current areas of training needs among Singapore dentists are in severe impairments of swallowing, communication, cooperation and mobility. Further geriatric dentistry training may effectively increase dentists' willingness to provide care; however, additional specific targeted interventions are also needed.

Perspectives of oral health therapists on the barriers to oral care provision in nursing homes in Singapore: A qualitative analysis

INTRODUCTION

Oral health therapists (OHTs) are a valuable resource for increasing access to dental care for the frail elderly in nursing homes (NHs). However, OHTs face several barriers and their skill-set continues to be under-utilized.

AIMS

To evaluate the perceptions of OHTs regarding the barriers towards oral care provision for the elderly residents in NHs.

METHODOLOGY

Semi-structured interviews were conducted with 11 OHTs to discuss the factors that may hinder them from providing oral health services in NHs. An inductive thematic analysis directed by the grounded theory approach was performed.

RESULTS

Four major themes emerged: (i) lack of opportunity, (ii) lack of adequate education and training, (iii) limited work scope and registration status, and (iv) lack of adequate financial remuneration and adequate equipment. OHTs also raised the lack of awareness among OHTs and the various stakeholders, of how the skill-set of OHTs may be relevant for oral care provision in NHs.

CONCLUSION

Findings revealed underlying educational and regulatory barriers which need to be addressed in tandem. Addressing these barriers can be impactful in informing future strategies for the greater utilization of the skill-set of OHTs in Singapore.

Interprofessional collaboration utilizing oral health therapists in nursing homes: Perceptions of oral health therapists and nursing home staff in Singapore

INTRODUCTION

Oral health therapists (OHTs) have the potential to increase the access to oral care for elderly residents in nursing homes (NHs).

AIMS

To evaluate the perceptions of NH staff and OHTs regarding the barriers and enablers toward oral care provision for elderly NH residents, and their perceptions toward interprofessional collaboration through the utilization of OHTs in NHs.

METHODOLOGY

Electronic surveys were completed by 231 direct care and 15 managerial staff from 15 NHs, and 103 OHTs. Factors influencing oral care provision, and aspects of awareness, capabilities, and willingness/interest toward collaboration were evaluated.

RESULTS

The OHTs and NH staff reported mutually positive responses toward interprofessional collaboration. The most frequently reported barriers by the NH staff were the lack of regular support from dental health professionals and inadequate knowledge and skills. The OHTs expressed willingness and competence in assisting the NH staff, but lacked regulatory and educational support.

CONCLUSION

OHTs have the potential to address the barriers faced by the NH staff, if adequately supported through policy and education. Oral health promotion in intermediate and long-term care sectors should take into account this potential for interprofessional collaboration through greater utilization of the skill-set of OHTs.

Effectiveness of sensory adaptive dental environments to reduce psychophysiology responses of dental anxiety and support positive behaviours in children and young adults with intellectual and developmental disabilities: a systematic review and meta-analyses

BACKGROUND

People with Intellectual and developmental disabilities (IDDs) experience oral health inequality due to myriad of risk factors and complex needs. Sensory processing difficulties, maladaptive behaviours and dental anxiety contribute to difficulties in receiving preventive and routine dental treatments. This study aimed to systematically review the evidence on the effectiveness of sensory adaptive dental environments (SADE) for children and young adults (up to the ages 24 years) with IDD to address cooperation and dental anxiety.

METHODS

This review was reported according to The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. MEDLINE (Ovid), The Cochrane Library, Embase, Google Scholar, Web of Science and OT Seeker were searched using appropriate terms to identify Randomised Control Trails (RCTs) that matched inclusion criteria. Screening was conducted by two reviewers after de-duplication based on titles and abstracts followed by full text retrieval. Quality of the included studies was assessed using Cochrane Risk of Bias (ROB)-2 for crossover trials and data extracted by two reviewers. The details of the interventions and effectiveness were compared and discussed narratively, and comparable outcomes were included to meta-analyses using R software.

RESULTS

A total of 622 articles were identified and five articles met eligibility for inclusion. Three studies used multi-sensory adaptations and one used single sensory adaptation of music. Narrative synthesis showed some evidence of SADE reducing magnitude and duration, although, questionable for reducing the number of maladaptive behaviours. Two studies demonstrated conflicting evidence of the effect of SADE on cooperation. Three studies demonstrated significant positive impact of SADE on psychophysiological outcomes. Despite an overall tendency to favour SADE, no statistically significant difference of maladaptive behaviours was found between SADE and regular dental environment (RDE) (Standardised mean change (SMC) = 0.51; 95% Confidence Interval (CI) -0.20 to 1.22; p = 0.161). SADE was superior to RDE (SMC -0.66; 95% CI -1.01 to -0.30; p =  < 0.001) in reducing psychophysiological responses of dental anxiety.

CONCLUSION

Current evidence suggests that adapting visual, tactile, and auditory aspects of the dental environment in a single or multi-sensory approach demonstrates small positive effects on psychophysiological responses and maladaptive behaviours of dental anxiety for people with IDD.

A General Assessment of India's Extremely Low Number of Transgender Cancer Patients

PURPOSE/OBJECTIVE(S)

Physiological transgender (TJ) is one of the most marginalized and oppressed community in the Indian subcontinent. The observable percentage of physiological transgender (TJ) cancer patients is extremely low. This concise report aims to assess the factors that contribute to the scarcity of transgender cancer patients.

MATERIALS/METHODS

The hospital database (2012-2021) of 2 centers in New Delhi (population 32 million) & 1 in Kolkata (15 million) were evaluated. In addition, 28 senior oncologists (ONC) and 17 trans women (TWs) completed a six-point questionnaire. ONC was asked how many TJ patients they had seen in their career, as well as histopathology/site. Furthermore, the data was extrapolated to account for all clinicians' cumulative years of experience. The questions for TWs were age and where they go if you have a disease or illness. And, do they know any TJ cancer patients?

RESULTS

India's last census (2011) revealed a half-million TJ population. TJ density must be at least 1 million to be comparable to the rest of the world. Hospital databases counted 10,486 patients, with no patient identified as TJ. A total of 37 TJ cancer patients were reported by 28 ONC with an average and collective years of their medical service of 23.1±4.1 and 646 years; distributed in 3 metropolis of 67 million (combined) population (Kolkata, New Delhi, and Mumbai). The average lifetime number of TJ cancer patients/oncologist was 1.3±1.1. Total 12 cases were head neck cancers, with 4 caused by human papillomavirus. The remaining 25 patients have 5 lung, 5 gynecological, 4 breast, 3 brain cancers, 2 soft tissue sarcomas, and 6 cases of unknown origin. The density of 5-year prevalent cancer cases in India is 0.2%, with an estimated 0.007% of TJ cancer patients. TW could not identify any cancer patients in their community.

CONCLUSION

Being transgender is a social taboo in this part of the world. Their legal rights and classification as the third gender are uncommon. TJs are denied access to standard education, mainstream occupations, and social respect. Although the exact number has never been determined, it is estimated that a large proportion (≈90%) of TJ people are forced to choose roadside begging and working as cheap sex workers. There is no clinical reason why TJs should have fewer cancer incidents, they should be more susceptible to cancer due to unhealthy living conditions, unprotected sex, lack of medical care, proper nutrition, and all other factors associated with their very low socioeconomic status. Nonetheless, it's difficult to find single TJ cancer patients in both public and private hospital OPD. They may be unable to access a traditional clinic due to social discrimination, financial constraints, or they may be unwilling to disclose their true sex. Even TJ's do not show up at free public clinics. The disclosure of true sex may be beneficial in obtaining better treatment, but the more prevalent reason is social unacceptability, which can be overcome through proper education and community economic growth.

Prevalence of Cleft Lip and Palate in the Developing Countries of Asia and Africa: A Review

Introduction: The objective of this paper is to review the literature on the incidence of cleft lip and palate (CLP) in the developing countries of Asia and Africa. The existing literature tends to focus on developed countries and there is lack of research in developing countries. Methods: The studies that met the inclusion criteria were reviewed and data extracted. There were 20 studies done in Asian and African countries which were included. Results: The incidence of CLP in Asian countries is markedly greater than in African countries. Most studies report a male predominance in CLPs and a female predominance in cleft palates. The male dominance is seen more than other developing countries which is consistent with other Asian countries and the same has been found in African countries. In the Nepalese study, females were slightly more affected than males among all clefts. The incidence or prevalence in the frequency and types of malformations of CLP in developing countries has been provided. Conclusions: The review underlines the need for an aggressive approach to prevent and control CLP in patients in developing countries.

Enabling people with severe mental illness to overcome barriers to access dental treatment: a qualitative study applying COM-B framework analysis

BACKGROUND

The oral health of people with severe mental illness is severely compromised. Rates of premature total tooth loss and tooth decay are substantially higher than in the general population. Causation is complex, restricted access to treatment a major contributing factor.

AIMS

To examine factors enabling people with complex problems related to severe mental illness to attend scheduled dental appointments.

METHOD

Qualitative semi-structured interviews were conducted with 15 service users who attended no-cost treatment at a university clinic, following oral health screening at an inner-city community mental health service. Analysis used a framework approach informed by a theoretical model of behaviour (COM-B).

RESULTS

Complex individual motivations, related variously to function, pain and/or self or social appraisal, were also influenced by expectations of treatment. Capabilities included managing "messy" life circumstances; participants overcame various psychological and physical challenges to attend treatment, enabled by opportunities of social and instrumental support.

CONCLUSIONS

Genuine partnerships between agencies to provide access opportunities, in addition to individual support responsive to personal motivators and adapted to capabilities can enable access to services and improve the lives of people with severe mental illness.

Inflammation and risk of recurrent cardiovascular events according to prior vascular disease location

Background

In recent years, anti-inflammatory drugs have been shown to reduce the risk of recurrent cardiovascular disease (CVD) events in patients with coronary artery disease (CAD), but have not yet been tested in patients with other vascular disease locations. Whether the relation between inflammation and recurrent CVD is modified by prior vascular disease location is unknown.

Purpose

This study aimed to establish the relation between low-grade inflammation and recurrent CVD according to prior vascular disease location.

Methods

Inflammation was measured by plasma concentrations of high-sensitivity C-reactive protein (CRP). Patients from the UCC-SMART cohort with CAD (n=4,517), cerebrovascular disease (CeVD; n=2,154), peripheral artery disease (PAD, n=1,154), or abdominal aortic aneurysm (AAA, n=424), and CRP ≤10 mg/L were included in the main analysis (combined n=8,249). Patients with CRP &gt;10 mg/L (n=756) were analysed separately. The primary outcome was a composite of myocardial infarction, ischemic stroke, or cardiovascular death. Secondary outcomes included the primary outcome components, major adverse limb events (MALE), and all-cause mortality. The relation between CRP and outcomes was assessed using Cox proportional hazard models stratified by prior vascular disease location, and adjusted for potential confounders.

Results

During a median follow-up of 9.5 years (interquartile range 5.1–13.9) 1,877 CVD events, 887 MALE events, and 2,341 deaths were observed. In the total population, CRP was related to recurrent CVD (hazard ratio [HR] per 1 mg/L 1.08; 95% confidence interval [CI] 1.05–1.10), and all secondary outcomes except for ischemic stroke (HR 1.03; 95% CI 0.99–1.08). Compared to the first quintile of CRP, HRs for recurrent CVD were 1.66 (95% CI 1.41–1.96) for the last quintile ≤10 mg/L, and 1.97 (95% CI 1.64–2.36) for the subgroup with CRP &gt;10 mg/L. CRP was related to recurrent CVD in patients with CAD (HR per 1 mg/L 1.08; 95% CI 1.04–1.11), as well as CeVD (HR 1.05; 95% CI 1.01–1.10), PAD (HR 1.08; 95% CI 1.03–1.13), and AAA (HR 1.08; 95% CI 1.01–1.15; p for interaction 0.815). The relation between CRP and all-cause mortality was stronger for patients with CAD (HR 1.13; 95% CI 1.09–1.16) compared to other locations (HRs 1.06–1.08; p=0.002).

Conclusion

Inflammation is an independent risk factor of recurrent CVD and mortality, irrespective of prior vascular disease location. Trials of anti-inflammatory drugs in patients with CeVD, PAD, and AAA are warranted.

Refractive and Binocular Vision Status and Associated Asthenopia among Clinical Microscopists

Background Clinical microscopists are at a greater risk of developing binocular vision anomalies and asthenopia. Objective To assess the refractive and binocular vision status and to explore the association between the presence of asthenopic symptoms and microscopy work among clinical microscopists working at medical laboratory department. Method This cross-sectional study involved 37 clinical microscopists working at medical laboratory department of Dhulikhel Hospital, Nepal. The study was conducted from January to December 2013. Only those participants who had been using microscope for at least a year were enrolled in this study. Each participant underwent distance visual acuity (VA) assessment, refractions, and orthoptic evaluation, including measurement of distance and near phoria, near point of convergence (NPC), near point of accommodation (NPA), positive fusional vergence (PFV), adduction, and calculation of accommodation convergence/accommodation (AC/A) ratio. The tear test was also carried out in each subject. Information about use of glasses, microscopy work (duration, and time spent per day in microscope), and visual symptoms associated with the use of microscope such as eye strain, headache, double vision, and near vision were collected. Result The mean age of the clinical microscopists was 29 ± 5.7 years. The prevalence of refractive error was 56.76% and the mean spherical equivalent (SE) refractive error was -0.77 ± 0.86 D. Refractive error had neither correlation with microscopy work and asthenopic symptoms associated with it, and nor with binocular vision parametersNPC, AA and AC/A ratio. However, there was a positive association between asthenopic symptoms and microscopy work. There was statistically significant difference between symptomatic and asymptomatic subjects for binocular vision parameters, including NPC, AA and positive fusional vergence (PFV) for near. Conclusion Microscopy work has an impact on near binocular vision. Asthenopic symptoms bear a positive association with microscopy work. Refractive error has no significant correlation with either microscopy works or associated asthenopic symptoms.

Evaluation of prognostic risk models for postoperative pulmonary complications in adult patients undergoing major abdominal surgery: a systematic review and international external validation cohort study

BACKGROUND

Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications.

METHODS

We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC).

FINDINGS

In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]).

INTERPRETATION

In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required.

Comparison of Hearing Result and Graft Uptake Rate between Temporalis Fascia and Tragal Cartilage in Endoscopic Myringoplasty

Background There are different methods to repair the perforation of the tympanic membrane. Recently cartilage has been used for the repair and results are comparable to temporalis fascia. For surgical procedure endoscope had added good assistance in middle ear surgery. Though the one hand technique the image quality and results are on par with the use of a microscope. Objective To compare the graft uptake rate and hearing results between temporalis fascia and tragal cartilage in endoscopic myringoplasty. Method This is a prospective, longitudinal study conducted among 50 patients who underwent endoscopic myringoplasty using temporalis fascia and tragal cartilage with 25 patients in each group. The hearing was assessed by comparing pre with post-operative ABG (Air bone gap) and ABG closure in speech frequencies (500Hz, 1 KHz, 2 KHz, 4 KHz). The status of graft and hearing results was evaluated on 6 months of follow up in both the groups. Result Out of total 25 patients enrolled for study in both (temporalis fascia and cartilage) groups, 23 (92%) patients in each group had graft uptaken. The audiological gain in the temporalis fascia group was 11.37±0.32 dB whereas in the tragal cartilage group it was 14.56±1.22dB. The audiological gain between the two groups did not show any statistically significant (p = 0.765). However, the pre and post-operative hearing difference was statistically significant in both temporalis fascia and tragal cartilage group. Conclusion Tragal cartilage has similar graft uptake rate and hearing gain when compared with temporalis fascia in endoscopic myringoplasty. Hence, tragal cartilage can be used for myringoplasty whenever required without any fear of deterioration in hearing.

Ischemic and Bleeding Profile of Patients on Dual Antiplatelet Therapy beyond 1 Year of Index Acute Coronary Syndrome / Percutaneous Intervention

Dual antiplatelet treatment (DAPT) is the cornerstone of the management and prophylaxis of acute coronary syndrome (ACS). However, the associated risk of bleeding with the usage of DAPT and risk of thrombosis with stoppage of the drug makes it a challenging task to take appropriate decisions regarding the choice and duration of DAPT. The present study is aimed to tackle these challenges and to analyze whether prolonged dual antiplatelet therapy carries more risk of bleeding or a higher risk of thrombosis is present with discontinuation of the same.

MATERIAL

In this study, a total of 235 cases of confirmed myocardial infarction, unstable angina, or those who underwent percutaneous intervention were included. After 1 year, the number of patients on DAPT, the type of antiplatelets they were using were observed, their ischemic risk was calculated using DAPT score, and bleeding risk was calculated using PRECISE-DAPT score. Bleeding events were assessed using BARC classification.

OBSERVATION

Out of 235 patients, the majority of the patients were males (78.7%). Only 7.2% of the patients had bleeding since the start of the drugs. The majority (5% out of 7.2%) of bleeding episodes were clinically insignificant. 163 (69%) patients were on Dual antiplatelet therapy after 1 year. Out of which 115 were appropriately taking DAPT as per their DAPT score. Patients with high bleeding risk (PRECISE DAPT score ≥25) were 89, out of which 38 (53.2%) patients were taking SAPT, appropriate for their bleeding risk. While 112 (68.7%) were taking prolonged DAPT, appropriate for PRECISE-DAPT risk.

CONCLUSION

The majority of patients remained on DAPT following discharge for more than 1 year after ACS. This suggests that treating physicians prioritizes ischemic risk reduction over bleeding risk in patients with ACS, according to the patient's risk profile.

Instantaneous wave-free ratio and fractional flow reserve: effect of variation in left ventricular end diastolic pressure

Funding Acknowledgements

Type of funding sources: None.

Introduction

Among patients with intermediate coronary artery stenosis (50-90%), assessment of functional significance of the lesion by instantaneous wave free ratio (iFR)/ fractional flow reserve (FFR) is recommended in latest guidelines. Though iFR is not much affected by change in hemodynamics compared to FFR, the change in iFR vs FFR due to various hemodynamic factors need a validation. Left ventricular end-diastolic pressure (LVEDP) is one of the hemodynamic factors whose variation and effect on FFR vs iFR is largely unknown. In the present study we evaluated the association of change in LVEDP on the changing pattern of iFR/FFR which may hold a clinical significance especially with percutaneous coronary intervention in heart failure patients.

Methods

This was a prospective, investigator-initiated, single-center study involving 20 patients with stable coronary artery disease and at least one intermediate coronary lesion (50-90%). The enrolled patients were subjected to both iFR and FFR along with baseline LVEDP measurement. Subsequently, intravenous nitroglycerine infusion was given to reduce LVEDP and corresponding iFR and FFR were re-evaluated. The dynamic changes in iFR and FFR were studied in relation to changes in LVEDP using Pearson’s correlation analysis and linear regression analysis.

Results

The mean LVEDP was lowered from 16.20 ± 1.54 mmHg to 9.50 ± 1.10 mmHg, the mean iFR and FFR got changed from 0.80 ± 0.12 to 0.76 ± 0.12 mmHg and 0.75 ± 0.09 to 0.72 ± 0.09 mmHg respectively. On Pearson’s correlation analysis, LVEDP change did not show statistically significant correlation (linear relationship) with iFR (p = 0.105, r2 = 0.373) and FFR (p = 0.227, r2 = 0.283) changes across the entire range of stenosis severity and in all vessels. Linear regression analysis did not state any independent correlation between LVEDP and iFR and FFR changes in the study group (p &gt;0.05). The % R2 value for iFR and FFR (as a coefficient of determination) of the regression equation were 13.9% and 8%, which means only these percentages of the total variance in iFR and FFR change were explained by LVEDP changes respectively. There was no serious adverse event related to the procedure.

Conclusion

To the best of our knowledge, this is the first study comparing the effect of changes in LVEDP on both iFR and FFR simultaneously. In our study, 1 mmHg change in LVEDP was associated with a change in FFR by 0.004 and change in iFR by 0.004 which didn’t reveal any significant association (p = 0.227 and 0.105 respectively). This helps us to put FFR at par with iFR under variable hemodynamics.  So either of the variables may be used interchangeably with confidence in varied hemodynamic conditions including patients with heart failure. The correlation was non-significant across entire range of stenosis severity, irrespective of sex, age, diabetes and hypertension. This study sets platform for further research with larger number of heterogeneous patient population. Abstract Figure. Box whisker plot

Role of oral flecainide in assessement of atrio-ventricular conduction in symptomatic bifascicular block

Background

Intravenous flecainide is used to stress Atrio-ventricular (AV) conduction in patients (pts) with a history of syncope & bifascicular (Bi-Fasc) block. Role of oral flecainide is unclear.

Objective

To assess effect of oral Flecainide on infra-Hisian AV conduction in patients with symptomatic Bi-Fasc block.

Methods

Pts presenting with syncope & Bi-Fasc block without advanced AVCD on ECG, 24 hr holter or treadmill exercise test were taken. Those with history suggestive of reflex syncope & positive tilt test were excluded. Remaining underwent electro-physiological (EP) study. Pts with HV interval &gt;100ms or intra/infra-Hisian block at rest or incremental pacing were subjected to PPI. Remaining received oral Flacanide 5 mg/kg (max 300 mg) & EP study was repeated after ½ hr, 1 hr, 2 hrs and 3 hrs. Primary end-point was HV ≥100ms or infra/intra-Hisian type IIB or III block.

Results

Of 41 pts enrolled for study, 28 patients (mean age 60.0 yrs, mean LVEF 60.7%) were eligible for EP Study. Basal PR interval was 185.8±47.4 ms & mean QRS width was 130.6±18.65 ms. On EP study, 4 (14.3%) with resting HV &gt;100 ms & 6 (21.4%) with HV &gt;100 ms on incremental pacing underwent PPI.

Out of remaining 18 pts who were given flecainide, 11 (66.1%) achieved primary endpoint (HV &gt;100 ms in 6, infra-hisian IIB in 2 and 2:1 block in 3 patients). At mean follow up of 6.5 months, 13 (59.1%) out of 22 with PPI had mean 59.1% VP & none of 6 remaining patients had any symptom.

Conclusion

Oral Flecainide significantly increases the diagnostic yield of EP study in patients with symptomatic bi-fasc block.

Comparison of traditional versus artificial intelligence based coronary artery disease risk prediction scores in young patients with acute coronary syndrome

Background

Ever since the concept of preventive cardiology has come into vogue, several risk identification models have come up which combine several risk factors to create a risk prediction score for occurrence of cardiovascular (CV) event. While carrying a proven validation in Western population, none of the risk prediction model has been satisfactorily evaluated in Indians especially young &lt;40 years old.

Objectives

To compare Artificial Intelligence based novel risk score with traditional risk scores in young (less than 40 years age) patients presenting with acute coronary syndrome (ACS) and to estimate the relative efficacy of different coronary artery disease (CAD) risk scores in young Indian Patients.

Design

Single center, Observational, Non-interventional study.

Participants

Cohort of Patients more than 20 but less than 40 years old with ACS in the department of Cardiology from 1st January 2019 to 31st October 2019.

Methods

314 young patients [mean age 36.14±4.17 years] presenting with acute coronary syndrome (ACS) were enrolled. The three clinically most pertinent risk assessment models [Framingham Risk score (FRS), World Health Organization risk prediction charts (WHO/ISH), and QRISK3 scores] and Artificial Intelligence based novel risk score (AICVD) were applied on day 1 of presentation, and tried to see whether one risk score versus other risk score could have predicted the event earlier had we applied it before the occurrence of ACS. Risk factors considered included those already in traditional scoring systems and new risk factors (diet, alcohol, tobacco, dyslipidemia, physical activity, family history of heart disease, history of heart disease, heart rate, respiratory rate, chronic heart symptoms and psychological stress).

Results

WHO/ISH provided the lowest high risk estimate with only 1 (0.9%) patient estimated to be having &gt;20% 10-year risk. The FRS estimated high risk (&gt;20% 10-year risk) in 3 (1%) patients. The QRISK3 estimated high risk (&gt;10% 10-year risk) in 20 (6.5%) patient. In comparison, AICVD risk prediction model stood tall by identifying 73 (23.2%) patients as high risk and 62.74% patients as more than moderate risk for having CV events at 7 years (p&lt;0.001).

Conclusion

Perhaps, this is the first study which has compared artificial intelligence based novel risk prediction model with the three most commonly applied models, in the young Indian patients. We found that a cohort of young Indian patients presenting with ACS, when studied retrospectively, was identified as “high risk” most likely by AICVD risk prediction model rather than the traditional counterparts. The WHO/ISH risk prediction charts and FRS were the poorest predictors. Performance of QRISK3 score also remained less than satisfactory. These findings suggested that AICVD risk prediction model is a promising tool to assess for CV risk in Indian population.

Oral Health Conditions and Treatment Needs of Children with Intellectual Disabilities Attending Special Olympics Australia

Purpose: To describe and evaluate the oral health status and dental treatment needs of children with intellectual disabilities attending Special Olympics in Australia from 2010 to 2018.<br/>Methods: This was a retrospective observational study. Children aged 18 years and younger with intellectual disabilities attending Special Olympics with their caregivers were screened between 2010 and 2018. Trained volunteer dentists performed the screening using the standardized Special Olympics Special Smiles protocol. Reported findings included presence or absence of untreated decay, filled teeth, missing teeth, trauma, fluorosis, and gingivitis as well as treatment urgency.<br/>Results: A total of 155 children with a mean age of 15 years participated in the dental screening in 2010, 2014, and 2018. Twelve percent reported oral pain, 15 percent needed urgent care, 21 percent had untreated caries, 39 percent had filled teeth, 39 percent had missing teeth, 59 percent had signs of gingival disease, 8.4 percent had fluorosis, and 13 percent had dental trauma. Mouthguards were recommended for 17 percent of child athletes. Missing teeth and filled teeth were significantly lower in 2014 compared to 2010 and 2018 (P <0.001).<br/>Conclusion: The burden of the untreated caries was not high in athletes attending the Special Olympics in Australia.

Event-Based but Not Time-Based Prospective Memory Is Related to Oral Health in Late Adulthood

BACKGROUND

Most evidence now indicates that cognitive function is related to poorer oral health in late adulthood, but that this relationship is not invariant across specific cognitive domains. Prospective memory (PM) is a core memory skill that refers to memory for future intentions and is known to be related to the formation of habits such as tooth flossing. However, the relationship between PM and oral health has been subject to only limited empirical study.

OBJECTIVE

The two studies reported in this paper were designed to test whether PM is related to oral health in older adults of varying vulnerability status.

METHODS

Study 1 sampled community-dwelling older adults (N = 172) living independently in the community; Study 2 sampled older adults living in a retirement village (N = 32). Participants in both studies were asked to complete a behavioural measure of PM, with their oral health indexed via self-report (Study 1) or an objective oral health exam (Study 2).

RESULTS

In both studies, relationships emerged between event-based PM and oral health, with Study 2 showing that these relationships were specific to oral health measures of plaque and calculus.

CONCLUSIONS

Older adults are particularly vulnerable to dental pathology, with important implications for their broader health and well-being. By showing that there is a relationship between oral health and a particular type of PM, this work will have potential implications for the development of more effective interventions focused on enhancing oral health outcomes in this group, such as those focused on strengthening habit formation.

Knowledge and Attitude on Eye Donation among Undergraduate Medical Students of Kathmandu University School of Medical Sciences, Nepal

Background Corneal blindness accounts for a significant proportion of avoidable visual impairment in developing countries. Eye donation is voluntary and awareness in undergraduate medical students being a future practitioner in any field are expected to be linked to patients during death in hospitals. Objective To assess the awareness of medical students on eye donation at Kathmandu University School of Medical Sciences (KUSMS). Method This was a cross-sectional study conducted among undergraduate medical students of KUSMS. Students' responses were recorded using a predesigned, pretested, semistructured questionnaire inquiring knowledge and attitude of eye donation, sources of information, their willingness to donate eyes as well as the reasons for donating/ not donating eyes. Result Less than half of the medical students (45.6%) were aware of eye donation only after death. Newspapers (72.2%) were the major source of information. The final year medical students were more aware (Average knowledge score = 11.56 ± 2.05) than their juniors. 80.7% of the students were willing to donate their eyes. The adjudged reasons for willingness to donate were that eye donation is a noble work and pleasure in helping a blind person while the reasons for unwillingness to donate were lack of awareness followed by family objection to eye donation. Conclusion Future medical practitioners possessed satisfactory knowledge about eye donation. Educating this cadre of human resources to sensitize them towards the need for eye donation would be a crucial step towards reducing the global burden of corneal blindness.

To the Point: Integrating the Obstetrics and Gynecology Core Clerkship into a Longitudinal Integrated Curriculum in US Medical Schools

The background, objectives, and outcomes related to LIC are discussed. Specific challenges and solutions for structuring an LIC in the context of obstetrics and gynecology are examined, which include student/faculty issues as well as process matters such as general infrastructure and specific curriculum concerns.

Simulation as a Platform for Development of Entrustable Professional Activities: A Modular, Longitudinal Approach

Background

The Association of American Medical Colleges (AAMC) has recently identified a list of integrated activities to be expected of all medical school graduates entering residency: the core Entrustable Professional Activities (EPAs). Direct observation and deliberate practice of individual EPA behaviors in the clinical setting has multiple challenges, and there is limited literature describing a comprehensive, longitudinal curriculum dedicated to formative EPA assessment. 

Approach

We present a model curriculum to develop and provide formative assessment of EPA skills longitudinally throughout the clinical years. Each EPA-focused training session includes a simulation case followed by several small group activities with content related to the clinical vignette in the initial simulation. We have designed this curriculum to be longitudinal and modular, and present the general framework here. 

Outcomes

Step-wise implementation began in 2013. Over 450 medical students have participated in the third year (MS3) clerkship sessions, 30 in the MS4 sub-internship sessions, and over 300 thus far in the fourth year (MS4) capstone course, including students from 10 different medical schools. MS3 sessions focused on EPAs 4, 7, 8, 9, 10, and MS4 sessions had an additional focus on EPA 8. The capstone course encompassed nearly all 13 EPAs in active simulation-based learning. Opportunities to provide formative assessment through on-the-spot feedback exist throughout the curriculum. Student feedback was overwhelmingly positive.

Next steps

We found that simulations are an effective method of providing formative assessment of EPAs that are exceptionally well-received by medical students. We have demonstrated that these can be implemented for medical students from multiple educational backgrounds. We believe that deliberate practice and longitudinal formative assessment is of utmost importance in effectively developing core EPAs prior to final entrustment decisions. 

Robust Simultaneous and Proportional Myoelectric Control Scheme for Individuals with Transradial Amputations

Commercial myoelectric prostheses need to be accurate and clinically viable to be successful. This study proposed a simultaneous and proportional control scheme with frequency division technique (SPEC-FDT) to address limitations in current myoelectric prosthesis control, specifically to address non-stationaries such as contraction level variations and unintended activations. Twenty able-bodied participants (14 males and 6 females, age 23.4 ± 3.0) and four individuals with transradial amputations performed wrist movements (flexion/extension, rotations and combined movements) in two degrees-of freedom virtual tasks. The SPEC-FDT had a completion rate (CR)>90% for both control and clinical participants which was significantly higher than the conventional technique (CR=68%). Our results showed that SPEC-FDT is highly accurate for both able-bodied and clinical participants and provides a robust myoelectric control scheme allowing for increased prosthetic hand functions.

A Narrative Review of Interventions to Teach Medical Students How to Break Bad News

Breaking bad news (BBN) is a key advanced communication skill that physicians must learn. Despite the breadth of literature describing patients' preferences and data citing poor physician competency in this arena, there remains significant dissatisfaction with how doctors deliver bad news. One way to solve this dilemma is to ensure that we are using the best evidence-based educational approaches to train the cadre of medical students who graduate from medical school each year. This article provides a 15-year review of articles on BBN in the undergraduate medical education curriculum that have been validated using the Medical Education Research Quality Instrument (MERSQI) (Acad Med 90:1067-76, 2015). This narrative review aims to identify articles which describe undergraduate medical education curriculum that evaluate how to best teach students to communicate bad news to patients. In the process, the authors reviewed 179 abstracts in 118 academic journals. Articles that met the inclusion criteria were evaluated using the MERSQI and those that scored higher than 11.3 were chosen for analysis. This paper summarizes the 15 articles that met the criteria. The review reveals (1) standard components which should be included in an undergraduate BBN curriculum, (2) a pressing need for utilizing a teaching and evaluation tool that incorporates nonverbal communication, and (3) a further need to test long-term curriculum retention.

Perioperative intravenous contrast administration and the incidence of acute kidney injury after major gastrointestinal surgery: prospective, multicentre cohort study

BACKGROUND

This study aimed to determine the impact of preoperative exposure to intravenous contrast for CT and the risk of developing postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery.

METHODS

This prospective, multicentre cohort study included adults undergoing gastrointestinal resection, stoma reversal or liver resection. Both elective and emergency procedures were included. Preoperative exposure to intravenous contrast was defined as exposure to contrast administered for the purposes of CT up to 7 days before surgery. The primary endpoint was the rate of AKI within 7 days. Propensity score-matched models were adjusted for patient, disease and operative variables. In a sensitivity analysis, a propensity score-matched model explored the association between preoperative exposure to contrast and AKI in the first 48 h after surgery.

RESULTS

A total of 5378 patients were included across 173 centres. Overall, 1249 patients (23·2 per cent) received intravenous contrast. The overall rate of AKI within 7 days of surgery was 13·4 per cent (718 of 5378). In the propensity score-matched model, preoperative exposure to contrast was not associated with AKI within 7 days (odds ratio (OR) 0·95, 95 per cent c.i. 0·73 to 1·21; P = 0·669). The sensitivity analysis showed no association between preoperative contrast administration and AKI within 48 h after operation (OR 1·09, 0·84 to 1·41; P = 0·498).

CONCLUSION

There was no association between preoperative intravenous contrast administered for CT up to 7 days before surgery and postoperative AKI. Risk of contrast-induced nephropathy should not be used as a reason to avoid contrast-enhanced CT.

Prevalence, Extent, and Severity of Oral Health Impacts Among Adults in Rural Karnataka, India

INTRODUCTION

Oral health affects quality of life. Many studies have investigated the factors associated with oral health-related quality of life (OHRQoL). Little is known about OHRQoL of adults living in rural and remote areas of India, where many have lower levels of education and limited availability of oral health care services.

OBJECTIVES

To determine the prevalence, extent, and severity of OHRQoL impacts associated with psychosocial factors, functional dentition, and patterns of dental visits among rural Indian adults between the ages of 35 and 54 y.

METHODS

A cross-sectional study was conducted with a multistage stratified sampling strategy targeting 35- to 54-year-olds. Interviews and oral examinations were performed to collect data on sociodemographic variables, Oral Health Impact Profile-14 (OHIP-14), patterns of dental visits, stress, tobacco and alcohol use, and dentition status. Univariate, bivariate, and multivariable analyses were done to determine the factors associated with prevalence, extent, and severity of OHIP-14 using SAS version 9.3.

RESULTS

There were 873 participants. Prevalence, extent, and severity of OHIP-14 were 13.4%, 0.5 (0.4-0.7), and 11.8 (11.2-12.5), respectively. The OHIP-14 impacts reported were not severe and mostly affected physical functioning. Levels of education, income, and number of functional teeth (FT) were inversely associated and last dental visit within the previous year was positively associated with prevalence, extent, and severity of OHIP-14. The prevalence of 1 or more oral health impacts was nearly 13% among rural middle-aged adults in India.

CONCLUSIONS

Low socioeconomic conditions, dental visits, and FT ≤19 were positively associated with prevalence, extent, and severity of oral health impacts.

KNOWLEDGE TRANSFER STATEMENT

This article provides data regarding OHRQoL of people in rural areas of a developing country. The study was intended to determine the factors associated with OHRQoL in rural people who are less educated and living in areas with minimal oral health care facilities. The findings of this study could potentially facilitate further research and health promotional activities for rural people of developing countries.

Universal Neonatal Hearing Screening: An Experience at Tertiary Care Hospital

Background Hearing loss among neonates is one of the important health issue in pediatric population which may remain unnoticed until the child reaches a certain age. The importance of universal early screening, diagnosis and intervention in reducing the negative impact of congenital hearing loss has been described all over the world. Objective To observe the outcome of hearing screening by Automated Auditory Brainstem Response (AABR) in newborns delivered in Dhulikhel Hospital and neonates admitted in an intensive care unit (NICU) of Dhulikhel Hospital. Method A prospective study was done in neonates who were born at Dhulikhel Hospital, Kathmandu University Hospital from February 15th, 2017 to October 30th, 2019. AABR was used for their hearing assessment within 24 hours of birth and again at about 6 weeks of age in those neonates who failed the initial test. All the neonates admitted in NICU were studied regarding the risk factors based on Joint committee on Infant Hearing. Those who failed the test for the second time were referred for detailed audiological diagnostic work up. Result The screening rate was 92.6% of the total deliveries. A total of 5517 neonates comprising of 2800 males and 2717 females were screened from total deliveries of 5956 neonates in the study period. Among them, NICU (sick) babies were 422 (7.7%) and well babies were 5095 (92.3%). Out of them, 1675 failed the test in the first screening and 374 failed in the second screening. So, the total number of referred babies in second screening was 6.7% (374) out of 5517 screened. Amongst them, well babies were 6.59% (336), out of 5095 screened and sick babies were 9% (38) out of 422 screened. Low birth weight and prematurity were found to be the commonest risk factor present among them, followed by the use of ototoxic medications, hyperbilirubinemia and prolonged use of mechanical ventilation. Conclusion Automated Auditory Brainstem Response (AABR) is a very useful tool for hearing screening which should preferably be done in all the neonates where possible. It should be done within one month of life and those with confirmed hearing loss should receive early appropriate intervention for better hearing in future.

This is a resource for medical educators, learners, and practicing clinicians from any field of medicine.

To the point: undergraduate medical education learner mistreatment issues on the learning environment in the United States

This article, from the To the Point series prepared by the Association of Professors of Gynecology and Obstetrics Undergraduate Medical Education Committee, is an overview of issues to consider regarding learner mistreatment and its effects on the undergraduate medical education learning environment in the United States. National data from the American Association of Medical Colleges Graduate Questionnaire and local data regarding learner mistreatment provide evidence that the learning environment at most medical schools needs to be improved. The American Association of Medical Colleges' definition of learner mistreatment focuses on active mistreatment, but data on passive mistreatment also contribute to a negative learning environment. The lack of tolerance for active mistreatment issues such as public humiliation and sexual and racial harassment need to be made transparent through institutional and departmental policies. Additionally, reporting mechanisms at both levels need to be created and acted upon. Passive mistreatment issues such as unclear expectations and neglect can also be addressed at institutional and departmental levels through training modules and appropriate communication loops to address these concerns. To fully confront and solve this challenging issue regarding learner mistreatment at the undergraduate medical education level, solutions to need to be implemented for faculty, residents, and students in the institutional, departmental, and clerkship settings.

4300Strain parameters at rest and after exercise in symptomatically stable patients with improved heart failure - STRESS-HF

Background

Optimal medical therapy (OMT) results in improvement in left ventricular (LV) ejection fraction (EF) and reduction in LV size in approximately 40% of patients of heart failure with reduced ejection fraction (HFrEF). Recent studies have proposed to continue treatment in all patients of this subgroup as improvement in LVEF does not indicate actual myocardial recovery. Global Longitudinal strain (GLS) is more sensitive marker of LV systolic function and better predictor of mortality than LVEF. GLS may identify probable patients in whom the therapy can be minimized or stopped.

Aim

To determine global longitudinal strain at rest and after exercise in patients with idiopathic dilated cardiomyopathy (DCM) who have improved LVEF ≥50% on guideline directed medical therapy (GDMT) and compare with resting & exercising LVEF on 3-dimesional (3D).

Material and methods

This Observational study was conducted in a tertiary care referral hospital, from February 2018 to October 2018. All patients with idiopathic DCM who had a documented LVEF of ≤40% in the past and improved LVEF (LVEF ≥50%) on GDMT were included in the study. Patients with secondary causes of HFrEF, poor echocardiographic window and inability to exercise were excluded from the study. Strain parameters were calculated at rest and after atleast 5 METS of exercise. GLS value of ≥ minus 12.6% was considered as mildly reduced strain, ≤ minus 8% as severely reduced strain and the values in between as moderately reduced strain. Post exercise, drop of >5% in absolute LVEF value or decrease in GLS >15% from baseline was considered as poor myocardial recovery.

Results

A total of 44 patients [mean age of 46.8±13.1 years and 24 males (54.5%)] constituted the study group. At the time of diagnosis, 31 (70.5%) patients were in NYHA class II and the remaining were in class III. Duration of GDMT ranged from 4 to 38 (median 12) months. Following improvement on GDMT, 25 (56.8%) were in class I and rest were in class II. Mean LVEF at diagnosis and after recovery was 33.6±4.9% and 55.1±4.5%, respectively with a mean absolute change in LVEF of 21.3±6.1%. At rest, mean 3D LVEF was 53±3.5% and GLS was −12.3±3.1. Mild, moderate and severely reduced strain was seen in 24 (54.5%), 13 (29.6%) and 7 (15.9%), respectively. After exercise, mean 3D LVEF was 51.5.±4.5% (mean decrease 1.5±2.1%) and mean GLS was −7±4.2% (mean decrease −5.3±4.6%). After exercise, none had a fall of LVEF >5% however 32 (72.7%) had a decrease of >15% in GLS. Seven (15.9%) patients had improvement in GLS, 4 (9.1%) had <15% decrease and 1 (2.3%) showed no change in GLS on exercise. The change in GLS on exercise was significant (p=0.001), but change in 3D LVEF was not significant (p=0.956).

Conclusion

Global longitudinal strain is a better marker for assessing myocardial recovery than LVEF in patients of heart failure with improved ejection fraction.

Oral and aural problems in Australian Special Olympics athletes

BACKGROUND

Associations between oral and aural problems among children have been explored, but not among adults with intellectual disability (ID), where often, oral and ear pain can be difficult to diagnose.

METHODS

Data included Special Smiles and Healthy Hearing screenings from two Special Olympics (SO) events held in Australia (2013-2014).

RESULTS

The SO athletes had poor oral health with a high prevalence (56.8%) of gingival signs and unmet dental needs (66.9%). Over one-third (33.9%) had partially/completely blocked ear canals, over one-fifth (20.7%) had possible middle ear problems, and almost one quarter (23.8%) had some hearing loss. No associations between oral and aural problems were found in the small sample (n = 130) of SO athletes.

CONCLUSIONS

Although SO athletes have unmet needs for both oral and aural health, access to appropriate hygiene care is an important preventive factor that athletes, families, and carers should be made aware of. Regular oral and aural screenings are recommended to identify problems early, because ability to communicate pain and discomfort can be different for this population. A larger sample of SO athletes with tooth and sextant level data could clarify the association between oral and aural problems in people with ID.

Factors Affecting Recanalisation after Optimal Management of Deep Vein Thrombosis; A single institution based study

Background Presence of recanalisation will favour for better physiological recovery after medical management of Deep Vein Thrombosis (DVT) along with lesser chances of post thrombotic syndrome. Rate of recanalisation is varied and can range from 43-57% and the factors that affect recanalisation are still a dilemma. Objective To know the factors for recanalisation following Deep Vein Thrombosis. Method This is a single institution based retrospective-prospective analytical study encompassing all ultrasonologically diagnosed cases of Deep Vein Thrombosis in adults from January 2015 to November 2017. All the cases were admitted with oral warfarin bridged by Heparin/ Enoxaparin and were discharged once International Normalization Ratio was in therapeutic range. The patients were followed up for three months with minimal of three outpatient followup. Best finding in the doppler ultrasonography (done by Acuson P500, Seimens) in relation to recanalisation was taken for the study. Result There were 67 cases of Deep Vein Thrombosis. Of these cases male to female ratio was 0.91. The mean age was 48.07. Most common extent was up to common femoral vein (47.8%) followed by upto popliteal vein (40.3%). Remaining 11.9% had extension upto iliac veins. There was no recanalisation in 2 cases (3%). Partial recanalisation was seen in 23 cases (34.3%) while complete recanalisation was seen in 42 cases (62.7%). Recanalisation is more in DVT involving popliteal vein while it decreases as the extension goes up. In contrast to 79.4% complete recanalisation in popliteal vein, that in common femoral vein is 62.5% while in iliac vein is only 37.5%. Mean age in no recanalisation group is much younger than partial or complete recanalisation groups. Conclusion Recanalisation following Deep Vein Thrombosis distal to popliteal vein is more than that in proximal Deep Vein Thrombosis. The information on recanalization can be considered to use to decide upon the duration of medical management of Deep Vein Thrombosis.
