Duchenne muscular dystrophy is a devastating neuromuscular disorder characterized by the loss of dystrophin, inevitably leading to cardiomyopathy. Despite publications on prophylaxis and treatment with cardiac medications to mitigate cardiomyopathy progression, gaps remain in the specifics of medication initiation and optimization.

This document is an expert opinion statement, addressing a critical gap in cardiac care for Duchenne muscular dystrophy. It provides thorough recommendations for the initiation and titration of cardiac medications based on disease progression and patient response. Recommendations are derived from the expertise of the Advance Cardiac Therapies Improving Outcomes Network and are informed by established guidelines from the American Heart Association, American College of Cardiology, and Duchenne Muscular Dystrophy Care Considerations. These expert-derived recommendations aim to navigate the complexities of Duchenne muscular dystrophy-related cardiac care.

Comprehensive recommendations for initiation, titration, and optimization of critical cardiac medications are provided to address Duchenne muscular dystrophy-associated cardiomyopathy.

The management of Duchenne muscular dystrophy requires a multidisciplinary approach. However, the diversity of healthcare providers involved in Duchenne muscular dystrophy can result in variations in cardiac care, complicating treatment standardization and patient outcomes. The aim of this report is to provide a roadmap for managing Duchenne muscular dystrophy-associated cardiomyopathy, by elucidating timing and dosage nuances crucial for optimal therapeutic efficacy, ultimately improving cardiac outcomes, and improving the quality of life for individuals with Duchenne muscular dystrophy.

This document seeks to establish a standardized framework for cardiac care in Duchenne muscular dystrophy, aiming to improve cardiac prognosis.

Fontan baffle punctures and creation of Fontan fenestration for cardiac catheterisation procedures remain challenging especially due to the heavy calcification of prosthetic material and complex anatomy.

We sought to evaluate our experience using radiofrequency current via surgical electrocautery needle for Fontan baffle puncture to facilitate diagnostic, electrophysiology, and interventional procedures.

A retrospective chart review of all Fontan patients (pts) who underwent Fontan baffle puncture using radiofrequency energy via surgical electrocautery from three centres were performed from January 2011 to July 2021.

A total of 19 pts underwent 22 successful Fontan baffle puncture. The median age and weight were 17 (3–36 years) and 55 (14–88) kg, respectively. The procedural indications for Fontan fenestration creation included: diagnostic study (n = 1), atrial septostomy and stenting (n = 1), electrophysiology study and ablation procedures (n = 8), Fontan baffle stenting for Fontan failure including protein-losing enteropathy (n = 7), and occlusion of veno-venous collaterals (n = 2) for cyanosis. The type of Fontan baffles included: extra-cardiac conduits (n = 12), lateral tunnel (n = 5), classic atrio-pulmonary connection (n = 1), and intra-cardiac baffle (n = 1). A Fontan baffle puncture was initially attempted using traditional method in 6 pts and Baylis radiofrequency trans-septal system in 2 pts unsuccessfully. In all pts, Fontan baffle puncture using radiofrequency energy via electrocautery needle was successful. The radiofrequency energy utilised was (10–50 W) and required 1–5 attempts for 2–5 seconds. There were no vascular or neurological complications.

Radiofrequency current delivery using surgical electrocautery facilitates Fontan baffle puncture in patients with complex and calcified Fontan baffles for diagnostic, interventional, and electrophysiology procedures.

COVID 19 has led to dramatic changes in the lives of people leading to an increase in stress and anxiety. Music intervention is a non-medicated method for relieving anxiety. This current study aims to understand whether music can be effectively used to alleviate anxiety in admitted COVID-19 patients.

To study the effect of music on anxiety in patients admitted for COVID-19 in a tertiary care hospital in New Delhi

34 patients (17 females &17 males) were randomly divided into two groups, a control (N=17) and a music group (N=17). Vitals of all the patients were noted. Patients of the music group were asked to listen to relaxing instrumental for 30 minutes, while patients of the control group were asked to relax for 30 minutes. Vitals of all the patients were noted again. Patients were asked to fill State Trait Anxiety Inventory (STAI) before and after intervention.

The post-intervention mean scores of STAI after the music session were lower in the music group than the control group [95.06 (SD 8.5)) versus 102.37 (SD 10.3)]. The differences in mean values of pre- to post-intervention changes between both groups after music session were statistically significant.

Our findings suggest that listening to music lowers anxiety. As music is non- invasive and free of side-effects we recommend that music intervention service should be used to improve health care quality.

No significant relationships.

Behavioural modification through increasing nutritional awareness, along with customised dietary changes and education about physical inactivity, for obese snorers and mildly sleep apnoeic patients would help improve their quality of life.

A one-year prospective interventional study enrolled snorers and/or mild obstructive sleep apnoea sufferers, with 36 patients each in the test group and control group. Nutritional information and tailor-made diet charts were given to the 36 test subjects. The severity of snoring and daytime sleepiness after 6 and 12 months was compared using the Epworth Sleepiness Scale and Thornton Snoring Scale as measures of quality of life.

Subjective scores on both scales showed highly significant improvement (p ≤ 0.001) in the test group. No significant improvement was seen in the control group.

Awareness of basic nutrition and customised diet plans help to achieve behavioural modification in the long term, resulting in a better quality of life.

Several aspects of the coronavirus disease 2019 (COVID-19) pandemic remain ambiguous, including its transmission, severity, geographic, and racial differences in mortality. These variations merit elaboration of local patterns to inform wider national policies.

In a retrospective analysis, data of patients treated at a dedicated COVID hospital with moderate and severe illness during 8 wk of the pandemic were reviewed with attention to mortality in a competing risks framework.

A total of 1147 patients were hospitalized, and 312 (27.2%) died in hospital. Those who died were older (56.5 vs 47.6 y; P < 0.0001). Of these, 885 (77.2%) had tested positive on reverse transcriptase polymerase chain reaction (RT-PCR), with 219 (24.2%) deaths (incidence rate, 1.9 per 100 person-days). Median time from onset of symptoms to death was 11 days. A competing risks analysis for in-hospital death revealed an adjusted cause-specific hazard ratio of 1.4 for each decade increase in age.

This retrospective analysis provides broad patterns of disease presentation and mortality. Even COVID test-negative patients will receive treatment at dedicated facilities, and 33% presenting cases may die within the first 72 h, most with comorbid illness. This should be considered while planning distribution of services for effective health-care delivery

The aim of study was to evaluate the pharmacotherapeutic efficacy of NDGA in experimental paradigm of depression i.e. olfactory bulbectomy (OB) specifically targeting kynurenine pathway.

Depression like behaviours was induced in OB mice and evaluated by assessment of various behavioural (olfactory deficit test, forced swim test, splash test, open field test, sucrose preference test), biochemical (catalase, reduced glutathione, SOD, nitrite, MAO-A, MDA, corticosterone), inflammatory cytokines (TNF- α, IL-1β, IL-6, IFN-γ) levels and alterations in delta sleep was recorded using EEG. Kynurenine pathway metabolites were determined in plasma and brain using HPLC method. After 14 days post-surgery, olfactory bulbectomized (OBX) mice were administered nordihydroguaiaretic acid (5 mg/kg, 10 mg/kg and 25 mg/kg) daily i.p.

We have developed a new HPLC method for simultaneous estimation of monoamines and kynurenine pathway metabolites in plasma and brain samples of mice. Chronic treatment with nordihydroguaiaretic acid significantly restored all behavioural, biochemical and neurochemical alterations in OBX mice and increase in quinolinic acid and decrease in kynurenic acid point out the neurodegeneration hypothesis of depression.

Nordihydroguaiaretic acid showed potent neuropharmacotherapeutic effect in OBX mice by virtue of its strong anti-oxidant, anti-inflammatory, anti-stress and by restoring quinolinic acid levels.

Endoscopes provide a magnified view of the middle ear and visualisation of hidden areas. Otoendoscopes facilitate excellent visualisation of the round window niche during cochlear implantation.

To compare microscopic and endoscopic visualisation of the round window membrane during cochlear implantation in 20 patients.

Twenty patients who underwent cochlear implantation were included in the study. After maximum exposure of the round window, the accessibility of the round window membrane was graded according to the St Thomas Hospital classification, first by microscope and then by endoscope.

With the use of the endoscope, visualisation of the round window membrane improved in all the patients as compared to the microscope. The electrode array was inserted via a round window or extended round window approach in all but two cases; the latter cases required bony cochleostomy because of unfavourable anatomy.

The main benefit of endoscope-assisted cochlear implantation is improved visibility of the round window region.

To compare combined conventional Freer medialisation and controlled synechiae, performed for middle meatal access (during the initial steps of functional endoscopic sinus surgery) and post-operative middle turbinate medialisation, with basal lamella relaxing incision, the latter of which is a single step for achieving both middle meatal access and post-operative medialisation. The study also compared the effects of controlled synechiae and basal lamella relaxing incision on post-operative olfaction.

A randomised prospective study was performed on 52 nasal cavity sides (32 patients). Only basal lamella relaxing incision was performed in one group, and both conventional medialisation and controlled synechiae were performed in the other. Intra-operative and post-operative photography was used to measure the middle meatal area. A pocket smell test was used to assess olfaction.

There were no significant differences in operative middle meatal access and post-operative medialisation of the middle turbinate. Post-operative olfaction was affected more in the combined conventional medialisation and controlled synechiae group, compared to the basal lamella relaxing incision group, but this finding was not statistically significant.

Basal lamella relaxing incision is an effective single-step technique for achieving adequate middle meatal access and post-operative medialisation, with no significant effect on olfaction.

This study aimed to compare the success rate of type I tympanoplasty in active (wet) and inactive (dry) mucosal chronic otitis media.

A prospective study was performed of 35 patients each with dry ear and wet ear undergoing type I tympanoplasty in the Otolaryngology Department, Postgraduate Institute of Medical Education and Research, India. All patients underwent type I tympanoplasty between January 2010 and June 2011 by the post-auricular approach. Samples of the remnant tympanic membrane were sent for histopathological examination.

After a minimum follow up of one year, the success rate was 88.6 per cent for dry ears and 80 per cent for wet ears. Neither the type (p = 0.526) nor the presence (p = 0.324) of discharge influenced the success rate. Histopathological examination of the tympanic membrane margins was performed for 46 patients: of these, 19 showed evidence of vascularity and 27 did not. There was no significant difference in success rate between groups (p = 0.115).

The success rate was not influenced by the presence of ear discharge at the time of surgery, and tympanic membrane vascularity did not influence graft uptake.
