How do Age at the Surgery and Birth Weight Influence Post-Operative Anthropometric Parameters in Infants with Surgical Closure of Large Ventricular Septal Defects? A Prospective Cohort Study from a Lower-Middle-Income Country

Closure of the large ventricular septal defects (VSD) in infancy can lead to normalization of growth, but data are limited. Our study is done to assess the growth pattern in different age groups of children and lower birth weight babies after shunt closure. This is a prospective observational study that included infants with isolated large VSD operated in infancy. Anthropometric data were collected at baseline and at follow-up, and growth patterns were analyzed. 99 infants were included in the study. The mean age and weight at the time of surgery were 6.97 ± 2.79 months and 5.07 ± 1.16 kg, respectively. The mean follow-up duration was 8.99 ± 2.31 months. The weight for age (W/A) was the most adversely affected parameter preoperatively, and there was significant improvement noted in the mean Z score for W/A after shunt closure (- 3.67 ± 1.18 vs. - 1.76 ± 1.14, p = 0.0012). There was improvement in Z-scores for length for age (L/A) and weight for length (W/L), although it was not statistically significant. The infants from all the age groups had statistically significant growth in the anthropometric parameters. The rate of weight gain was maximum in the infants operated below 8 months of age (2-4 months = 3588 g, 5-6 months = 3592 g, 7-8 months = 3606 g, 9-10 months = 2590 g, 11-12 months = 2250 g). Low birth weight and normal birth weight infants had similar Z-scores at the time of surgery and at follow-up in all 3 anthropometric parameters, and birth weight did not affect pre- as well as post-operative growth parameters. Suboptimal improvement in weight and length was seen in 40 and 20% of babies even after successful surgical repair, respectively. Growth failure in infants with a large VSD can be multifactorial. Early surgical closure of the shunt can lead to early normalization of growth parameters and faster catch-up growth. Few babies may fail to demonstrate a positive growth response even after timely surgical correction, and may be related to intrauterine and genetic factors or faulty feeding habits.

Trans-catheter closure of an unusual type of Abernethy malformation in a child presenting with severe pulmonary hypertension

Abernethy malformation is a congenital extra-hepatic porto-systemic shunt. This malformation is characterized by an abnormal connection between the portal vein or its branches and one of the systemic veins. Though rare, this anomaly can lead to pulmonary hypertension. Drainage of Abernethy malformation into coronary sinus is extremely rare. We describe a child with Abernethy malformation with unusual drainage into coronary sinus. The abnormal channel was successfully closed by trans-catheter technique with normalisation of pulmonary arterial pressures.

Pseudoaneurysm of aorta after transcatheter closure of patent ductus arteriosus

Aortic pseudoaneurysm is a rare but life-threatening complication after transcatheter closure of patent ductus arteriosus (PDA) with only a few reported cases in literature. We report a case of an 18-month-old child who was diagnosed to have pseudoaneurysm of the aorta after 6 months of transcatheter closure of PDA. It was diagnosed on routine follow-up on echocardiography evaluation. Computed tomography chest is the imaging modality of choice for evaluation of these patients which showed large saccular aneurysm arising from distal aortic arch beyond origin of left subclavian artery. Any aneurysm more than 30 mm should be treated irrespective of symptoms. Treatment modalities are surgical resection of the aneurysm (as in our patient) or thoracic endovascular aortic repair. In our case, surgical resection of aneurysm was performed.

Inhaled iloprost as an add-on therapy for advanced pulmonary arterial hypertension: An Indian perspective

Background Pulmonary arterial hypertension (PAH) is a progressive disease with high morbidity and mortality. Risk stratification and initiation of dual or triple combination therapy has a better clinical response, especially in high-risk patients. Unfortunately, prostacyclin analogues are not marketed in India; hence, the use of these medications is limited. We report the benefits and difficulties of using iloprost inhalation in patients with advanced PAH in India. Methods In this prospective observational study, we included patients with group 1 PAH. Inhaled iloprost was initiated as an add-on therapy for patients who had clinical, echocardiographic or laboratory deterioration on dual oral medications. Patients with clinical instability were excluded. All patients underwent thorough clinical evaluation, detailed echocardiogram and laboratory investigations. Patients were started on inhaled iloprost 2.5 μg six times daily and closely followed up. The dose was escalated if necessary. On follow-up, clinical echocardiographic and laboratory evaluation was done on all patients. Results Fourteen patients (11 women) with a median age of 32 years (2-66 years) with group 1 PAH were started on inhaled iloprost as an add-on therapy. Improvement in clinical parameters, WHO functional class, echocardiographic-derived right ventricular function, and N-terminal pro-brain natriuretic peptide (NT-pro-BNP) levels were observed in 10 of 14 patients. A median increase of 31% (4.2, 106%) in the distance travelled during 6-minute walk test, a median increase of 45% (-20, 120%) in right ventricular fractional area change, a median increase of 27% (-16.7, 60%) in tricuspid annular peak systolic excursion and a median decrease of 36.7% (-69.6, 17.2%) in NT-pro-BNP levels were observed after initiation of medication. Three patients had progression of symptoms and were then referred for lung/heart-lung transplant. One patient developed progression of symptoms after an excellent initial response and transitioned to subcutaneous treprostinil. Improvement in clinical, echocardiographic and laboratory features allowed us to successfully perform surgical Potts shunt in 2 patients. The medications were well tolerated with minimal and transient side-effects. There were no deaths. Conclusion Inhaled iloprost can be used with acceptable benefits and minimal side-effects in patients with PAH.

Anal Canal Adenocarcinomas: Prognostic Factors and Outcomes at a Single Institution

PURPOSE/OBJECTIVE(S)

Adenocarcinomas of the anal canal (AAC) represent a rarity among cancers of the digestive tract. Data guiding management is limited to retrospective studies and optimal treatment paradigms of AAC are still evolving. Here, we aim to investigate their prognostic factors and outcomes.

MATERIALS/METHODS

We reviewed anorectal adenocarcinoma patients who underwent curative-intent neo/adjuvant therapy +/- surgery at a single institution from 2015-2019. AAC were defined as tumor epicenters ≤ 2 cm from the dentate line. Our primary outcome was 5-year overall survival (OS). We also analyzed 5-year local recurrence, distant metastasis, and disease-free survival (DFS), defined as the interval after treatment completion to the first occurrence of local, regional, distant recurrence, or death. All tumors were staged according to the Rectal Cancer paradigm per AJCC 7th Staging. Kaplan-Meier and Cox-Proportional Hazards Model were used for survival analyses.

RESULTS

In our cohort, 57 patients met inclusion criteria. Median follow-up time was 54 months. The median age was 64 years; 35% of the cohort was female. The majority of tumors were adenocarcinomas (77%), with a minority of mucinous (12%) and signet ring cell (11%) histologies. The median tumor size was 4 cm, located 1 cm from the anal verge. Most tumors (63%) were grade 2, 77% had T3 disease, and 53% had clinical nodal involvement. Most patients completed neoadjuvant chemoradiation, total mesorectal excision, and adjuvant chemotherapy (54%). Fifty-four percent underwent abdominopelvic resection. Of those who received neoadjuvant therapy, 11% achieved a pathologic complete response. Seventy percent of patients completed chemotherapy, either in the neoadjuvant or adjuvant setting. At 5 years, local recurrence was 9%, regional pelvic recurrence was 12%, inguinal nodal recurrence was 2%, and distant recurrence was 25%. Five-year DFS was 63% and 5-year OS was 70%. Multivariate analysis demonstrated age, female gender, CEA, grade 3 disease, mucinous histology, and nodal involvement to be prognostic of lower OS. Receipt of neo/adjuvant chemotherapy was found to be prognostic of higher OS (HR 0.13, p<0.05).

CONCLUSION

In this cohort, the majority of whom received surgical management, we show numerically similar or higher overall survival in comparison with prior studies. This study is limited by its retrospective nature and sample sizes of an exceedingly rare entity. Receipt of neo/adjuvant chemotherapy appears to have an impact on survival. Further investigation is needed to explore the role of total neoadjuvant therapy in improving outcomes in this patient population.

A randomized controlled trial evaluating a theory driven, complex intervention centered on task sharing and mobile health to improve selfcare and outcomes in heart failure - The PANACEA-HF RCT: Design and rationale

Background

We developed a three-pronged complex intervention to improve selfcare and deliver whole person care for patients with heart failure, underpinned by the 'extant cycle' theory - a theory based on our formative work.

Methods

This is a 3 centre, 2-arm, 1:1, open, adaptive stratified, randomized controlled trial. We included patients aged ≥ 18 years with heart failure, taking any of the key guideline directed medical treatments, with a history of or currently on a high ceiling diuretic. We excluded end stage renal disease, clinically diagnosed severe mental illness or cognitive dysfunction and having no caregivers. Interventions included, (i) trained hospital based lay health worker mediated assessment of patients' current selfcare behaviour, documenting barriers and facilitators and implementing a plan to 'transition' the patient toward optimal selfcare. (ii) m-health mediated remote monitoring and (iii) dose optimization through a 'physician supervisor'.

Results

We recruited 301 patients between Jan 2021 and Jan 2022. Mean age was 59.8 (±11.7) years, with 195 (64.8 %) from rural or semi-urban areas and 67.1 % having intermediate to low health literacy. 190 (63.1 %) had an underlying ischemic cardiomyopathy. In the intervention arm, 142 (94.1 %) had a Selfcare in Heart Failure Index (SCHFI) score of ≤70, with significant barriers being 'lack of knowledge' 105 (34.5 %) and 'behavioural passivity' 23 (7.5 %).

Conclusion

This is the first South Asian trial evaluating a complex intervention underpinned by behaviour change theory for whole person heart failure care. These learnings can be applied to heart failure patient care in other resource constrained health systems.

Manipulation of distal radius fractures: a comparison of Bier's block vs haematoma block

INTRODUCTION

Displaced distal radius fractures often require manipulation under anaesthesia. Many anaesthetic techniques are described, with the two most commonly used being Bier's block (BB) and haematoma block (HB). Despite national guidance preferring a BB, an HB is often performed instead. This study aims to compare the analgesic properties of a BB with those of an HB when manipulating distal radius fractures.

METHODS

This is an observational cohort study comparing the management of displaced distal radius fractures requiring reduction across two National Health Service trusts. Patients aged over 18 with isolated, displaced distal radius fractures were recruited. Patient demographics, AO fracture classification and grade of clinician performing the procedure were recorded. A numeric rating scale (NRS) pain score was obtained for each patient after manipulation. The quality of reduction was judged against standardised anatomical parameters.

RESULTS

Some 200 patients were recruited (100 HB, 100 BB). There were no differences in age (BB: median 66.5 years, interquartile range [IQR] 55-74; HB: median 67 years, IQR 55-74; p = 0.79) or fracture characteristics (p = 0.29) between cohorts. Patients undergoing BB had significantly lower pain scores with a lower IQR than those undergoing HB (p < 0.005). Patients undergoing BB manipulation were more likely to have the fracture reduced and normal anatomy restored (p < 0.005). BBs were performed mainly by Foundation Year 2 junior doctors, whereas HB manipulations were performed by a range of clinicians from emergency nurse practitioners to consultants.

CONCLUSIONS

BB provides better analgesia than an HB. This can be performed successfully and reliably by Senior House Officer-level junior doctors.

Clinical profile and outcomes of multisystem inflammatory syndrome in children associated with COVID-19 virus after surgery for congenital heart defects

Introduction

To study the clinical presentation, laboratory profile, echocardiographic details, management, and outcomes of children who were diagnosed to have multisystem inflammatory syndrome in children (MIS-C) in the immediate postoperative period after surgery for congenital heart defects (CHDs).

Materials and Methods

This is a prospective case-control study that included children diagnosed to have MIS-C in the postoperative period based on clinical signs, rise in inflammatory markers, and echocardiographic features of ventricular dysfunction or coronary involvement. Management included intravenous immunoglobulin (IVIG), steroids, and antiplatelet medications in addition to routine postoperative care. Out of the 461 children who underwent surgery for CHD between April 1st, 2021, and November 30th, 2021, 18 children were diagnosed with MIS-C. After the initial routine postoperative course, all 18 children had sudden worsening in clinical and laboratory parameters. Other causes such as bacterial infection were ruled out. All of these children had features of MIS-C with ventricular dilatation and dysfunction, coronary artery involvement, and reactive COVID-19 immunoglobulin G antibody. There was a significant improvement in coronary artery dimensions after IVIG administration (P = 0.001). The involvement of the left main coronary artery was associated with significantly increased length of intensive care unit (ICU) and hospital stay (P = 0.019). Mean ICU and hospital stay was prolonged in the MIS-C group. There were two deaths in this group due to severe left ventricular dysfunction.

Conclusions

During the pandemic, a proportion of patients undergoing elective cardiac surgery may develop unexpected worsening in clinical status due to MIS-C. A high index of suspicion and prompt treatment with IVIG and steroids may be helpful in improving outcomes.

Effect of a video-assisted fall prevention program on fall incidence in community-dwelling older adults during COVID

BACKGROUND

The study evaluated the effectiveness of a video-assisted exercise intervention program on fall incidence, activities of daily living, and fear of falling in community-dwelling older adults.

METHODS

A video-assisted 16-week exercise intervention consisting of stretching, strengthening, balance, and dual-task training was delivered to randomly selected 95 older adults with a high risk of falls. The fidelity of implementation was assessed for three areas; exercise program delivery, participant receipt, and enactment.

RESULTS

The fall incidence reduced significantly by 45% (IRR 0.55, (95% CI, 0.13-0.86) and difficulty in daily activities decreased (OR: 0.74, 95% CI, 0.16 - 0.96) among participants in the intervention group. Fear of falls did not show any significant difference in the groups at the 12-month follow-up.

CONCLUSION

The video-assisted exercise program was found to be effective in reducing fall incidence among older adults at a higher risk of falls.

A COMPARATIVE STUDY OF FALL RISK ASSESSMENT IN COMMUNITY DWELLING OLDER ADULTS IN INDIA

Falls in older adults can be prevented with early identification. Recent research investigates the use of wearable sensors to provide quantitative data on mobility parameters to assess risk of fall. However, the efficiency of these new methods in comparison to conventional fall risk assessment tools is unknown. Therefore, the current study compares the sensor-based fall risk assessment with conventional fall risk measures. The study included 659 community-dwelling older adults (&gt;60 years) who were followed for 12 months after baseline. The American Geriatric Society Fall Risk Assessment tool was used to assess risk of fall conventionally and Kinesis QTUG was used to assess the fall risk using sensors. Receiver operating characteristics curve (ROC) was used to compare the sensor-based method and the conventional method of assessing fall risk. Out of the 659 community-dwelling older adults, 24% (163) of older adults reported a fall in 12 months. According to the sensor-based assessment, 23% of older adults had low risk, 50% had medium risk and 27% had high risk of fall and according to the conventional method 66.1% were in low risk, 27.1% were in medium risk and 6.8% were in high risk. The ROC analysis showed that the sensor-based methods (AUC-78%; sensitivity- 93.8% specificity – 56.3%) outperformed the conventional method (AUC – 61.2%; sensitivity – 82.8% and specificity - 67.2%) of identifying older adults at risk of fall. Therefore, use of simple wearable sensors can determine the risk of future falls.

Guidelines for physical activity in children with heart disease

Justification

In recent years, there has been increasing recognition of children with heart disease in our country. These children belong to different age groups and have untreated, partially treated, or completely treated heart disease. The role of physical activity for optimal physical, emotional, and psychosocial well-being for children is well understood. There is a challenge for the parents and the medical professionals to take a decision regarding the type of physical activity safe for the child as heart disease may affect the hemodynamic demands. Most of the existing international guidelines focus on competitive sports in operated heart disease children. This may be of limited use when we have a mixed population of children with heart disease, different types of sports in our country and where a larger subset is looking for recommendations to leisure time activities.

Process

The Pediatric Cardiac Society of India decided to formulate recommendations for physical activity in children with heart diseases. A committee of experts, who were well-versed with the subject of physical activity in children with heart disease, volunteered to take up the task of writing the guidelines. The recommendations emerged following deliberations of the committee members, on the virtual platform as well as mails. The final version of manuscript was approved by all committee members and all members are co-authors of this manuscript. The different types of physical activities were defined including leisure sports and competitive sports. The exercise was classified based on the mechanical action of muscles involved into dynamic and static components. Each type of exercise was then classified based on the intensity into low, medium, and high. Recommendations for the type of physical activity for individual heart lesions were decided based on the rationale available.

Objectives

The recommendations here are made with an intention to provide general guidelines for physical activity in children with operated and unoperated heart diseases, not excluding a need for individualizing a plan, serial assessment, and comprehensive checkup in special situations.

Recommendations

We hope the recommendations mentioned below would provide basic clarity in planning physical activity in children with heart disease. This is with the hope to encourage physically active life, at the same time ensuring a safety net.

1028 Systematic Review of Outcomes of Applications of Prineo-Dermabond

Aim

The aims of this study are to assess published data regarding infection rates, delayed wound healing, cosmetic appearance and application time compared to conventional wound closure techniques across multiple surgical procedures.

Method

A literature search was conducted according to PRISMA guideline using PubMed, SCOPUS and Science Direct. The primary outcome was the incidence of wound infection after Prineo Dermabond compared to controls. Secondary outcome measures included allergic reactions and time for application. Literature search identified 52 studies, of which 19 were eligible for qualitative synthesis and 12 for meta-analysis.

Results

Studies included reflected a broad range of applications of Dermeo-Prineo to wound closure in Abdominoplasty, Mammoplasty and Arthroplasty.

Overall, all studies reporting on time of application found a positive indicator of Prineo Dermabond reducing time for wound closure.

Meta-analysis identified a statistically significant reduction in rates of the 6 studies that described wound infection (Prineo 1.51%, Control N=2.13%, OR 0.65 (0.46–0.91); P=0.01) and in the 5 studies reporting delayed wound healing (Prineo 0.99%, Control N=1.79%, OR 0.42 (0.18–0.98); P=0.05) in the use of Prineo Dermabond versus controls.

Three studies reported outcomes of scar cosmesis or long-term maturation. All attested to better cosmetic results in comparison to sutures.

Two studies discussed cost-effectiveness of Dermabond with a hypothetical model concluded that Skin Closure System of Prineo Dermabond could achieve savings of $50–76 per patient, whilst a retrospective model found no statistically significant difference in Total Hospital costs or Operating room time.

Conclusions

Prineo Dermabond provides an alternative method of wound closure in reported studies.

Identification of a novel mutation in thyroxine-binding globulin (TBG) gene associated with TBG-deficiency and its effect on the thyroid function

PURPOSE

This study presents a case of familial transmission of thyroxine-binding globulin (TBG) deficiency. The SERPINA7-gene which codes for TBG is located on the X-chromosome (Xq21-22). More than 45 mutations have been reported to cause TBG- deficiency from various countries, but none from India so far. Genetic analysis of SERPINA7 gene was carried out to determine the cause of low TBG levels in one family.

METHODS

DNA samples of the propositus and the family members were subjected to Polymerase Chain Reaction (PCR) followed by direct sequencing. Allele-specific PCR and Next-gen sequencing (NGS) were employed to confirm the site of the mutation. Thyroid function tests were estimated by Radioimmunoassay (RIA) and Immunoradiometric assay (IRMA) kits. X-chromosomal inactivation status was analyzed in the female members harboring the mutation.

RESULTS

A mutational screening in this family revealed a novel frame-shift mutation S353Q, 354fs3X in the exon 4 of the SERPINA7 gene which will be referred to as TBG-complete deficiency-India (TBG-CD-Ind). One out of four female family members harboring the mutation showed selective X-chromosomal inactivation. The affected family members were clinically euthyroid initially, showed changes in the thyroid function when tested after a long time span. However, the changes in the thyroid function in the affected family members had an autoimmune etiology.

CONCLUSION

This study presents the first report of TBG-CD from India wherein a novel frameshift mutation referred to as TBG-CD-Ind (S353Q, 354fs3X) in the SERPINA7 gene was detected. No apparent association was identified between thyroid function and the TBG-mutation in the affected subjects. A detailed biochemical and genomic testing to determine the exact cause of discordant TFT in the patients would certainly aid in the unequivocal diagnosis of the thyroid function and for the precise individualized treatment.

Association between daily activities and fall in older adults: an analysis of longitudinal ageing study in India (2017-18)

Background

Declining functionality affects an individual’s musculoskeletal integrity increasing the risk of fall and disability. Individuals with severe functional limitations are 5 times more likely to experience a fall. Thus, this paper investigated the association between functional decline and falls in older adults.

Methods

This study uses secondary data from the Longitudinal Aging Study in India (2017–18). A total of 31,477 people over the age of 60 are included in the study. Descriptive statistics and bivariate analysis were performed to determine the association between activities of daily living (ADL), instrumental activities of daily living (IADL) and fall. Adjusted odds ratio was used to determine the association of ADL and IADL with fall while controlling for age, gender, balance and gait impairments.

Results

The study reported 6352 fall episodes in 3270 participants aged 60 and above, over a period of 2 years. More than 30% of participants reported difficulty in ADL and IADL. Age and gender adjusted odds of fall were higher in participants with difficulty in more than 4 ADLs (AOR:1.32; CI:1.08 – 1.67) and in more than 2 IADL (AOR: 1.39; CI:1.02 – 1.89). Similarly, the odds of fall were higher for difficulty in ADL (AOR:1.31; CI:1.11 – 1.73) and IADL (AOR of 1.18; CI:1.07 – 1.29) controlling for gait and balance impairment. Difficulty in pushing-pulling objects (AOR: 1.30; CI: 1.15 – 1.46 & AOR: 1.40; CI: 1.21–1.61) and getting up from the chair (AOR: 1.12; CI:1.01–1.26 & AOR: 1.27; CI: 0.99 – 1.26) was significantly associated with fall when adjusted for age, gender and balance and gait parameters.

Conclusions

This study provides the new insights into the association of fall and risk of functional decline, especially difficulty in pushing and pulling objects and getting up from a chair, can be incorporated in the primary screening of fall risk assessment.

Multipoint dosing strategy for scale-up of exothermic aromatic nitration.

Transcatheter closure of congenital portosystemic shunts – A multicenter experience

Background:

Congenital portosystemic shunts (CPSS) are rare and present variably with hepatic encephalopathy, pulmonary arteriovenous malformations (PAVMs), and pulmonary hypertension (PH).

Objective:

The objective of the study was to see the feasibility of transcatheter closure of CPSS and their outcome.

Materials and Methods:

We analyzed the data of 24 patients of CPSS who underwent transcatheter closure from five institutions (March 2013 to April 2019). Baseline evaluation included echocardiography with bubble contrast study, ultrasound examination of the abdomen, computed tomography angiogram, and cardiac catheterization with test balloon occlusion of the CPSS. The evaluation showed cyanosis due to PAVM in 12, PH in 8, and respiratory distress in 2. Two had both cyanosis and PH. Criteria for eligibility for complete catheter closure of CPSS included demonstration of intrahepatic portal vein (PV) radicals together with a PV pressure of ≤18 mmHg on occlusion.

Results:

The median age and weight were 8 years (0.5–21) and 19.5 kg (4.2–73), respectively. Transcatheter closure was performed in 21 patients (22 procedures) using a variety of occlusive devices and stent-graft exclusion was done in one patient. Closure was not done in 3 in view of high portal venous pressures and hypoplastic PVs. During the follow-up (median: 42 months and range: 61 days–4.8 years), saturation normalized in 14 patients with PAVM. PH declined in all eight patients who underwent the procedure. Respiratory distress improved in two patients.

Conclusions:

Early and short-term follow-up results of catheter closure of CPSS appear promising. However, further, follow-up is needed to demonstrate long-term effectiveness.

Effect of Video assisted Home-Based exercise intervention on fall risk and gait parameters in older adults in India

Countries across the globe recommended isolation to protect older adults from COVID-19 infection. However, this led to decreased mobility and physical inactivity potentially increasing their risk of fall. The study was conducted in a group of 88 older adults between 60-74 years with known gait impairments and high fall risk. The participants were part of our cohort study on fall prevention program. Fall risk and gait impairments were measured using wearable sensors during the Timed-up and go test (TUG) at baseline. Using technology, a 16-week video assisted home based exercises intervention was delivered to reduce fall risk and improve gait parameters. The intervention consisted of flexibility, strengthening, balance and gait training exercises given progressively through one video session per week. The participants performed these exercises at home for the rest of the week. A home visit immediately after 16th week was arranged to collect post intervention parameters. Results showed an average 20% decrease in fall risk post intervention. An overall large effect size with Cohen’s d of 0.90 was reported for fall risk. Significant difference in TUG time (Z = -4.610, p&lt; 0.000), stride velocity (Z= -5.035, p&lt;0.000), stride length (Z = -5.867, p&lt;0.000), time taken to stand (Z = -7.363, p&lt;0.000) and time taken to turn (Z = -6.079, p&lt;0.000) was observed in the post-test measurements as compared to pre-test measurements. Therefore, we conclude that video assisted exercise programs can be highly beneficial as alternatives to in person exercise intervention to prevent falls during COVID-19 isolation.

A case of "acquired" cor triatriatum

Cor triatriatum sinister is a rare congenital cardiac anomaly. It consists of a fibro-muscular membrane that separates the left atrium into two chambers resulting in a tri-atrial heart. It is often found in association with other structural cardiac anomalies. The "acquired" form is extremely rare and only anecdotal reports are found in literature. We describe a case of acquired cor triatriatum following surgical repair of coronary sinus type of total anomalous pulmonary venous connection (TAPVC), which presented 11 years after initial repair of TAPVC.

Insights into complex nanopillar-bacteria interactions: Roles of nanotopography and bacterial surface proteins

Nanopillared surfaces have emerged as a promising strategy to combat bacterial infections on medical devices. However, the mechanisms that underpin nanopillar-induced rupture of the bacterial cell membrane remain speculative. In this study, we have tested three medically relevant poly(ethylene terephthalate) (PET) nanopillared-surfaces with well-defined nanotopographies against both Gram-negative and Gram-positive bacteria. Focused ion beam scanning electron microscopy (FIB-SEM) and contact mechanics analysis were utilised to understand the nanobiophysical response of the bacterial cell envelope to a single nanopillar. Given their importance to bacterial adhesion, the contribution of bacterial surface proteins to nanotopography-mediated cell envelope damage was also investigated. We found that, whilst cell envelope deformation was affected by the nanopillar tip diameter, the nanopillar density affected bacterial metabolic activities. Moreover, three different types of bacterial cell envelope deformation were observed upon contact of bacteria with the nanopillared surfaces. These were attributed to bacterial responses to cell wall stresses resulting from the high intrinsic pressure caused by the engagement of nanopillars by bacterial surface proteins. Such influences of bacterial surface proteins on the antibacterial action of nanopillars have not been previously reported. Our findings will be valuable to the improved design and fabrication of effective antibacterial surfaces.

Impact of COVID-19 pandemic on pediatric cardiac services in India

BACKGROUND

COVID-19 pandemic has disrupted pediatric cardiac services across the globe. Limited data are available on the impact of COVID.19 on pediatric cardiac care in India.

AIMS

The aims are to study the impact of COVID-19 pandemic on the care of children with heart disease in India in terms of number of outpatient visits, hospitalizations, catheter-based interventions, and cardiac surgeries.

SETTINGS AND DESIGN

This is a retrospective, multicentric, observational study.

METHODS

We collected monthly data on the number and characteristics of outpatient visits, hospitalizations, catheter-based interventions, and cardiac surgeries and major hospital statistics, over a period of 5 months (April to August 2020), which coincided with the first wave of COVID-19 pandemic in India and compared it with data from the corresponding months in 2019.

RESULTS

The outpatient visits across the 24 participating pediatric cardiac centers decreased by 74.5% in 2020 (n = 13,878) as compared to the corresponding period in 2019 (n = 54,213). The reduction in the number of hospitalizations, cardiac surgeries, and catheterization procedures was 66.8%, 73.0%, and 74.3%, respectively. The reduction in hospitalization was relatively less pronounced among neonates as compared to infants/children (47.6% vs. 70.1% reduction) and for emergency surgeries as compared to elective indications (27.8% vs. 79.2%). The overall in-hospital mortality was higher in 2020 (8.1%) as compared to 2019 (4.8%), with a higher postoperative mortality (9.1% vs. 4.3%).

CONCLUSIONS

The current COVID-19 pandemic significantly impacted the delivery of pediatric cardiac care across India with two-third reduction in hospitalizations and cardiac surgeries. In an already resource-constrained environment, the impact of such a massive reduction in the number of surgeries could be significant over the coming years. These findings may prove useful in formulating strategy to manage subsequent waves of ongoing COVID-19 pandemic.

Basic gait pattern and impact of fall risk factors on gait among older adults in India

BACKGROUND

An unstable gait pattern is an indicator of an increased risk of falls among older adults. Data on basic gait parameters is useful in the early identification of gait impairment. However, reference gait measurements are not available in low- and middle-income countries.

RESEARCH QUESTION

What are the normative reference values of gait parameters and do fall risk factors such as impaired balance, functional difficulty, and multimorbidity affect the gait patterns of older adults in India?

METHODS

A cross-sectional data of 659 older adults were collected using a semi-structured schedule. Gait parameters were measured using wearable sensors. Descriptive statistics, independent t-test, and one-way ANCOVA were used to determine the significant difference (p < 0.05) in gait parameters across the risk factors.

RESULTS

A mean stride length of 123.00 ± 15.19 cm, stride velocity of 110.57 ± 17.57 cm/s, and a cadence of 106.14 ± 11.44 steps/minute were reported in the study. Functional difficulties and balance impairment were the two major risk factors that affected stride velocity, stride length, and cadence after adjusting for age and height. No difference in gait parameters was observed among participants with and without multimorbidity.

SIGNIFICANCE

This study provides a baseline or reference values of various gait parameters measured on a large sample of population aged 60 and above from India. Assessment of gait patterns and associated risk factors in a clinical setup will help identify the older adults at risk of falls and reduce the enormous burden of fall injuries. Since gait parameters show a large variation across geographical regions, it is important to have region-specific reference values.

Outcome of COVID-19-positive children with heart disease and grown-ups with congenital heart disease: A multicentric study from India

BACKGROUND

Outcome data of children with heart disease who acquired COVID-19 infection are limited.

AIMS

We sought to analyze outcome data and identify risk factors associated with mortality in children with heart disease and grown-ups with congenital heart disease (GUCH) who had a laboratory-confirmed COVID-19 infection.

SETTINGS AND DESIGN

This is a retrospective, multicentric, observational study.

MATERIALS AND METHODS

The study included children with heart disease and GUCH population, who presented with either symptomatic or asymptomatic COVID-19 infection to any of the participating centers. COVID-19-negative patients admitted to these centers constituted the control group.

RESULTS

From 24 pediatric cardiac centers across India, we included 94 patients with a median age of 12.5 (interquartile range 3-96) months and 49 (52.1%) patients were males. Majority (83 patients, 88.3%) were children. One-third of the patients (n = 31, 33.0%) had acyanotic congenital heart disease, and 41.5% (n = 39) were cyanotic, with > 80% of the patients being unoperated. Only 30 (31.9%) patients were symptomatic for COVID-19 infection, while the rest were incidentally detected positive on screening. A total of 13 patients died (case fatality rate: 13.8%). The in-hospital mortality rate among hospitalized patients was significantly higher among COVID-19-positive cases (13 of 48; 27.1%) as compared to COVID-negative admissions (9.2%) during the study period (P < 0.001). On multivariate analysis, the independent predictors of mortality among COVID-19-positive cases were severity of illness at admission (odds ratio [OR]: 535.7, 95% confidence interval [CI]: 6.9-41,605, P = 0.005) and lower socioeconomic class (OR: 29.5, 95% CI: 1.1-814.7, P = 0.046).

CONCLUSIONS

Children with heart disease are at a higher risk of death when they acquire COVID-19 infection. Systematic preventive measures and management strategies are needed for improving the outcomes.

Annular pancreas causing pyloric stenosis in a 66-year-old patient treated with gastrojejunostomy: a case report

Annular pancreas is defined by a ring of pancreatic tissue encircling the descending portion of the duodenum. It is exceptionally rare in adults and commonly diagnosed during the investigation of symptoms arising due to its complications. Treatment usually involves the surgical correction with a duodenoduodenostomy, gastrojejunostomy or duodenojejunostomy. We discuss the case of a 66-year-old male patient who presented with symptoms of gastric outlet obstruction and was found to have an annular pancreas encircling the pylorus and the first and second portions of the duodenum and was treated by performing a gastrojejunostomy. Upper gastrointestinal series, computerized tomography (CT) scans, and magnetic resonance cholangeopancreatographys can all be used for preoperative diagnosis; however, endoscopic retrograde cholangiopancreatography (ERCP) is the diagnostic modality of choice. Nonetheless, many patients may only be diagnosed intraoperatively, especially those who cannot undergo an ERCP due to stenosis proximal to the duodenum or patients in whom the annulus may not be visible on CT scan.

Potts shunt as an effective palliation for patients with end stage pulmonary arterial hypertension

BACKGROUND

Potts shunt has been suggested as an effective palliative therapy for patients with pulmonary artery hypertension (PAH) not associated with congenital heart disease.

MATERIALS AND METHODS

This is a prospective single-center study performed to assess outcomes of Potts shunt in patients with PAH who are in functional class III or IV.

RESULTS

52 patients in functional class III/IV with pulmonary arterial hypertension without significant intra or extracardiac shunt on maximal medical therapy were evaluated and counseled for undergoing Potts shunt/patent ductus arteriosus (PDA) stenting. 16/52 patients (13 females) consented for the procedure; 14 patients underwent surgical creation of Potts, and 2 underwent transcatheter stenting of PDA, which physiologically acted like a Potts shunt. Standard medical therapy was continued in patients who did not consent for the procedure. 12/16 patients survived the procedure. Patients who did not survive the procedure were older, with severe right ventricular systolic dysfunction, and functional class IV. Patients who survived the procedure were followed up in the pulmonary hypertension clinic. The Median follow-up was 17 months (1-40 months). 11/13 patients discharged after the operation showed sustained clinical, echocardiographic, and biochemical improvement, which reduced need for pulmonary vasodilator therapy in 10/13 patients. There was one death in the follow-up period 16 months post-surgery due to lower respiratory tract infection.

CONCLUSION

Potts shunt is feasible in patients with PAH without significant intra or extracardiac shunts. It can be done safely with an acceptable success rate. Patient selection, preoperative stabilization, and meticulous postoperative management are essential. It should be performed at the earliest sign of clinical, echocardiographic, or laboratory deterioation for optimal outcomes. Long-term follow-up is required to see a sustained improvement in functional class and the need for a lung transplant in the future.

Congenital extrahepatic portocaval malformation: Rare but potentially treatable cause of pulmonary hypertension

OBJECTIVE

Abernethy malformation (congenital extrahepatic portosystemic shunt) is a rare anomaly of the splanchnic venous system. Though rare, it is an important cause of pulmonary artery hypertension (PAH) which is often missed. All patients with PAH should be carefully evaluated for presence of Abernethy malformation before labelling them as Idiopathic PAH.

METHODS

This is a retrospective analysis of prospectively collected data. We reviewed the data of all patients referred to our center for evaluation of PAH. 10 patients were diagnosed to have an extrahepatic portocaval malformation. We reviewed their presentation, diagnosis, catheterization data, intervention and their outcome along with review of literature.

RESULTS

10/104 patients with pulmonary hypertension and no intra or extracardiac shunt were found to have extrahepatic portocaval shunt (EHPCS). 3 patients had EHPCS type 1 and 7 had type 2 EHPCS. 6/7 patient with EHPCS type 2 underwent closure of the shunt. There was no procedure related complication. There was one death 3 months post procedure and one patient who was advised surgical closure was lost to follow up. Closure of the shunt resulted in normalization of the pulmonary artery pressures in 4/5 patients.

CONCLUSION

Congenital portosystemic malformations form an important and potentially treatable cause of pulmonary hypertension.

Elective delayed sternal closure portends better outcomes in congenital heart surgery: a retrospective observational study

Introduction

Delayed sternal closure is used in paediatric cardiac surgery as a management strategy for patients with unstable hemodynamics or postoperative bleeding routinely. We hypothesise that planned postponement of sternal closure leads to better outcomes than emergent reopening in the intensive care unit (ICU) in patients exhibiting some hemodynamic indication for the same.

Methods

We retrospectively analysed the outcomes of delayed sternal closure 220/2111 (10.42%) out of which 14 sternums were opened in the ICU after shifting the patients.

Results

A total of 220/2111 (10.42%) sternums were left open postoperatively, out of which 14 were opened after shifting to the ICU. Total mortality of the delayed sternal closure was 33/220, i.e. 15%. The patients whose sternums were left open from the theatre had a mortality of 23/206, i.e. 11.16%, whereas those patients whose sternums were opened in the ICU had a mortality of 10/14, i.e. 71.42%.

Conclusion

In doubtful postoperatively hemodynamic, the choice of leaving the sternum open electively has better outcomes, rather than opening the sternum as a terminal bail out procedure.

Correlates of Functional Limitations in Midlife: A Cross-Sectional Study in Middle-Aged Men (45-59 Years) from Pune

Background and Objective

The present article aims to determine the correlates of functional limitation in middle-aged men (45-59 years age) in the slums of Pune, India.

Materials and Methods

A total of 553 community-dwelling middle-aged men were randomly selected from the study area. Data on demographic characteristics, health-related conditions, and social and psychological determinants of health were collected using a pretested, structured questionnaire. Functional ability was assessed using the Pune-Functional Ability Assessment Tool. Univariate analyses and bivariate logistic regression analyses were carried out to examine the associations between various correlates and functional limitations.

Results

A total of 55.2% of the respondents displayed functional limitations. Univariate analysis identified significant correlates of functional limitations, which were increasing age, nature of the occupation, presence of chronic diseases, self-reported aches and pains, vision problems, previous hospital admission, and stress. Binary logistic regression displayed the higher odds of having functional decline in men with age above 55 years (odds ratio [OR] = 2.592; 95% confidence interval [CI] = 1.597-4.207), unskilled occupation (OR = 1.681; 95% CI = 1.050-2.692), chronic disease (OR = 2.608; 95% CI = 1.553-4.378), and reporting aches and pains (OR = 6.605; 95% CI = 3.732-11.689) as compared to their counterparts.

Conclusion

This study has identified the magnitude of functional decline and its risk factors for midlife men. These study findings suggest that men having several risk factors should be monitored to protect against accelerated functional loss. These findings are important because functional decline has implications on older adult's health and disease conditions. A better understanding of these factors will help to develop health promotion interventions for men in midlife.

•

POCUS has a high sensitivity for pulmonary manifestations of COVID-19.

•

POCUS minimises nosocomial spread.

•

POCUS can prognosticate and assess response to therapy.

•

Healthcare providers with skills in POCUS are encouraged to help provide this service.

Single-Stage Repair of Interrupted Aortic Arch With Aortopulmonary Window and Bovine-Type Aortic Arch Complicated by Left Subclavian Artery Origin Stenosis-A Case Report

An aortopulmonary window is known to be associated in 5% of interrupted aortic arch cases. The combination of these lesions with a bovine-type aortic arch is much more uncommon. We report its embryological explanation and successful single-stage surgical repair in a three-month-old infant.

Bio-social determinants of health-related quality of life of middle aged (45-59 years) population in India

Purpose

Inadequate research on midlife health-related quality of life particularly in low-and-middle-income countries has often led to poor recognition of the issues in health programmes and policy. To address these concerns, this study was aimed at examining health-related quality of life and its determinants in middle-aged (45–59 years) men and women in low-resource settings in India.

Methods

Data on health-related quality of life and other relevant parameters were collected from 1112 individuals between 45 and 59 years of age from an urban agglomeration of Pune, India. Independent t-test was used to determine the association between means of Short Form-12 and other variables. Multilinear regression analyses were conducted to study the direction of these associations.

Results

The mean physical and mental component scores were 45.33 (±8.88) and 51.48 (±9.87), respectively. After adjusting for other variables, functional impairment emerged as a common factor that was negatively associated with physical and mental component scores of men (PCS: −5.557, 95%CI = −6.793 to −4.322; MCS:−1.816, 95% CI = −3.443 to −0.189) and women (PCS: −7.985, 95%CI = −9.782 to −6.188; MCS;  = −2.289, 95% CI = −4.160–0.419). Good life satisfaction was positively associated with physical scores in men (2.300, 95%CI =  1.180 to 3.421) and mental scores in women (3.066, 95%CI  =  1.333 to 4.798). Unemployment, sitting hours (>3) and no physical activity affected men, while lower education, marital status, body mass index and chronic illness affected health-related quality of life of women at midlife.

Conclusions

Functional decline, level of life satisfaction and stress affected health-related quality of life of middle-aged individuals in India.

Botulinum toxin in the management of temporomandibular disorders: a systematic review

The aim of this review was to critically investigate and assess the evidence relating to the use and efficacy of botulinum toxin (BTX) in the management of temporomandibular joint disorders (TMD) and masticatory myofascial pain. A comprehensive search was conducted of PubMed, Scopus, Embase, and Cochrane CENTRAL, to find relevant studies from the last 30 years up to the end of July 2018. Seven were identified. Three showed a significant reduction in pain between the BTX and placebo groups and one showed a clinical, but not a significant, difference. In one that compared BTX with another novel treatment, myofascial pain reduced equally in both groups, and in the remaining two there was no significant difference in pain reduction between the BTX and control groups. Of the four studies that assessed mouth opening, two reported that BTX had resulted in a slight improvement; one reported no improvement, and the other a worsening of the condition. A meta-analysis was not possible because of the considerable variation in the studies' designs, the heterogeneity between the groups, and the different assessment tools used. Despite showing benefits, consensus on the therapeutic benefit of BTX in the management of myofascial TMD is lacking. Further randomised controlled trials with larger sample sizes, minimal bias, and longer follow-up periods are now needed.

Indian Guidelines for Indications and Timing of Intervention for Common Congenital Heart Diseases: Revised and Updated Consensus Statement of the Working Group on Management of Congenital Heart Diseases. Abridged Secondary Publication

JUSTIFICATION

A number of guidelines are available for management of congenital heart diseases from infancy to adult life. However, these guidelines are for patients living in high income countries. Separate guidelines, applicable to Indian children, are required when recommending an intervention for congenital heart diseases, as often these patients present late in the course of the disease and may have co-existing morbidities and malnutrition.

PROCESS

Guidelines emerged following expert deliberations at the National Consensus Meeting on Management of Congenital Heart Diseases in India, held on 10th and 11th of August 2018 at the All India Institute of Medical Sciences, New Delhi. The meeting was supported by Children's HeartLink, a non-governmental organization based in Minnesota, USA.

OBJECTIVES

To frame evidence based guidelines for (i) indications and optimal timing of intervention in common congenital heart diseases; (ii) follow-up protocols for patients who have undergone cardiac surgery/catheter interventions for congenital heart diseases.

RECOMMENDATIONS

Evidence based recommendations are provided for indications and timing of intervention in common congenital heart diseases, including left-to-right shunts (atrial septal defect, ventricular septal defect, atrioventricular septal defect, patent ductus arteriosus and others), obstructive lesions (pulmonary stenosis, aortic stenosis and coarctation of aorta) and cyanotic congenital heart diseases (tetralogy of Fallot, transposition of great arteries, univentricular hearts, total anomalous pulmonary venous connection, Ebstein anomaly and others). In addition, protocols for follow-up of post surgical patients are also described, disease wise.

P4396Patients explanations of self-care in chronic heart failure: a grounded theory analysis of qualitative data from PANACEA-HF Phase 1

Background

Sub-optimal self-care and non-adherence to treatments are important predictors of poor clinical outcomes in patients with heart failure. Task-sharing and technology have each contributed modest improvements, but the combined effect on outcomes is unknown. We aim to develop a complex intervention package to improve self-care predicated on task sharing and smartphone based remote monitoring among heart failure patients.

Purpose

As a formative step, we conducted a qualitative study among heart failure patients and their caregivers to explore self-care and to inform the development of a contextualized intervention package.

Methods

We conducted in-depth interviews among 22 patients admitted to in-patient wards with a clinical diagnosis of chronic heart failure (diagnosis made at least 1 month prior to index hospitalization) and 18 caregivers (n=40), sampled from 4 states in southern India. Patients were purposively sampled based on sex, socioeconomic status, health literacy and past one month's history of adherence to heart failure medications. The middle range theory of self-care informed the drafting of the interview guide. We recorded and transcribed interviews translated from 5 regional languages. We inductively coded the data from a social constructionist viewpoint, created categories, prepared memos, compared extreme cases, identified key emergent themes and their inter-relationships.

Results

Patients' mean age was 60.5 (±13.4), with representation from socioeconomic strata, urban and rural areas. Patients had a high pill burden [median 10; IQR (6, 31)] and 8 (44%) reported irregular adherence to prescribed medications in the last month. Key categories associated with sub-optimal self-care included “Passivity”, “Entrenched Belief systems”, “Negative Emotions/Affect”, “Ageing causes disease”, and “inability to control situations” across all socioeconomic strata. These themes appear to impair self-actualization that negatively impacts self efficacy/confidence and in turn self-care reciprocally (Refer Figure). Key facilitators of self-care were: Intrinsic patient distinctive facilitators (situational awareness, resilience) and extraneous facilitators (insurance/financial protection, positive caregiver relationships and ease of healthcare access). Patients and caregivers generally expressed their readiness to use mobile technology for remote monitoring and to be counseled by trained lay workers to address beliefs and be trained on self-care.

Framework explaining self-care in HF

Conclusions

Findings from this formative study show opportunities for providers and community-based care workers to address task-sharing of beliefs by educating patients on self-care, including through the use of technology-based solutions. These findings regarding a self-care framework identify opportunities to improve self-care among heart failure patients using task-sharing and technology to support the patient-caregiver-provider triad.
