Angiotensin Receptor-Neprilysin Inhibitor Therapy and Cardiac Remodeling in Heart Failure: Consensus Statement from India

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

Role of Iron Therapy in Heart Failure: A Consensus Statement from India

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

Cinnamon: an aromatic condiment applicable to chronic kidney disease

Cinnamon, a member of the Lauraceae family, has been widely used as a spice and traditional herbal medicine for centuries and has shown beneficial effects in cardiovascular disease, obesity, and diabetes. However, its effectiveness as a therapeutic intervention for chronic kidney disease (CKD) remains unproven. The bioactive compounds within cinnamon, such as cinnamaldehyde, cinnamic acid, and cinnamate, can mitigate oxidative stress, inflammation, hyperglycemia, gut dysbiosis, and dyslipidemia, which are common complications in patients with CKD. In this narrative review, we assess the mechanisms by which cinnamon may alleviate complications observed in CKD and the possible role of this spice as an additional nutritional strategy for this patient group.

Metastatic Mature Teratoma and Growing Teratoma Syndrome in Patients with Testicular Non-Seminomatous Germ Cell Tumors

Metastatic mature teratoma is a common radiologic and histopathologic finding after chemotherapy for metastatic nonseminomatous germ cell tumors. The leading theory for these residual tumors is the selective chemotherapy resistance of teratomas versus the high chemotherapy sensitivity of the embryonal components. Growing teratoma syndrome is a relatively rare phenomenon defined as an enlarging residual mass histologically proven to be a mature teratoma in the setting of normal serum tumor markers. Metastatic mature teratomas should be resected because of their malignant potential and occasional progression to growing teratoma syndrome with the invasion of the surrounding structures. CT is the preferred imaging modality for post-chemotherapy surveillance and should cover all sites of potential metastatic disease. This article reviews the clinical, pathologic, and multimodality imaging features of metastatic mature teratomas in patients with primary testicular non-seminomatous germ cell tumors.

Computer Based Learning Modalities In Anatomy Dissection

Background: Cadaveric dissection has been used for centuries for teaching gross anatomy all over the world. Ithas been considered as a necessity to learn gross anatomy and helps the medical students in understanding thethree-dimensional relationship of different anatomical structures and variations. But the paucity of cadaversand high financial cost has considerably contributed to the development of alternative teaching techniques.Advancement in web-based medical technology leads to the development of virtual dissection programs. Theseprograms have been found to be an effective way to teach anatomy and are being preferred over cadavericdissection. Is cadaveric dissection simply a rite of passage or is it a necessity? The aim of our study was todetermine whether cadaveric dissection is a necessity in medical education, and if it can be replaced by neweralternative techniques like computer based dissection procedure.Materials and Methods: A batch of 150, 1st MBBS students of Malla Reddy Institute of Medical Sciences, Hyderabadwere studied by dividing them into 2 groups of 75 each after subjecting them to Conventional based Learning(CNVL) of dissection versus Computer Based Learning (CBL). A questionnaire was given to both the students andthe faculty. Based on the response to the questionnaire statistical analysis was done.Results: The present study indicated that the Computer Based Learning in dissection (CBL) method was found tobe more effective method for teaching anatomy by 79% of the students and 84% of faculty doctors. The valuer=0.89 shows the pre & post score has correlated positively and has an effect of study. (Paired Two Sample t-test:p=3.24E-29<0.05). As well the results were found to be increased with the pre (35%) to post test (65%) and p<0.05implies the effect.Conclusion: The three dimensional (3D) modeling of anatomical structures in the human body was presented indetailed step by step cadaveric dissections. It also provided detailed human anatomical training for students,where there is a lack of cadaver facility and where there are more students to cadaver ratio. Thus, the multimediaequipped interactive anatomical laboratory software enhance both memorization and visual learning skills ofthe medical students

Effectiveness of abdominal compression in reducing internal target motion during conformal radiotherapy for carcinoma stomach – A pilot study

AIM: To assess the effectiveness of abdominal compression in reducing internal target motion during conformal radiotherapy for stomach cancer. MATERIALS AND METHODS: A pilot study was conducted on five patients who received adjuvant radiotherapy for stomach cancer. All the patients had surgical clips and were offered radiotherapy and concurrent chemotherapy as per the institutional protocol. An abdominal compression device was developed consisting of a triangular Styrofoam's plate and an inflatable air bladder that was positioned over the patients' abdomen. The pneumatic pressure was set according to the patients' comfort. On the simulation day, patients had two computed tomography (CT)-scanning sessions, with and without abdominal compression. Target volumes and organs at risk (OAR) were delineated on the CT images without compression. On the treatment day, fluoroscopy was acquired with onboard imager (OBI) and movements of surgical clips with and without compression analyzed with the help of a tracker software. Observed values with and without abdominal compression were compared. RESULTS: Abdominal compression usage has reduced the mean breathing excursion (MBE) in medio lateral(ML) direction from 5.92mm to 4.15 mm and in cranio caudal direction (CC) from 11.3mm to 7.2mm. The range of reduction by 29.85% in the ML and 36.86% in CC direction. The average residual breathing excursion was 1.766 mm (SD = 1.33 mm) in the ML and 4.02 mm (SD = 2.18 mm) in the CC direction, respectively. CONCLUSION: Abdominal compression was useful in reducing internal target motion during stomach cancer conformal radiotherapy. The device we developed is patient friendly and cost-effective.

Minimally-Invasive versus Conventional Repair of Spondylolysis in Athletes: A Review of Outcomes and Return to Play

Spondylolysis from pars fracture is a common injury among young athletes, which can limit activity and cause chronic back pain. While current literature has examined the relative benefits of surgical and conservative management of these injuries, no study has yet compared outcomes between conventional direct repair of pars defects and modern minimally invasive procedures. The goals of surgery are pain resolution, return to play at previous levels of activity, and a shorter course of recovery. In this review, the authors have attempted to quantify any differences in outcome between patients treated with conventional or minimally invasive techniques. A literature search was performed of the PubMed database for relevant articles, excluding articles describing conservative management, traumatic injury, or high-grade spondylolisthesis. Articles included for review involved young athletes treated for symptomatic spondylolysis with either conventional or minimally invasive surgery. Two independent reviewers conducted the literature search and judged articles for inclusion. All studies were classified according to the North American Spine Society standards. Of the 116 results of our initial search, 16 articles were included with a total of 150 patients. Due to a paucity of operative details in older studies and inconsistencies in both clinical methods and reporting among most articles, little quantitative analysis was possible. However, patients in the minimally invasive group did have significantly higher rates of pain resolution (p<0.001). Short recovery times were also noted in this group. Both groups experienced low complication rates, and the majority of patients returned to previous levels of activity. Surgical repair of spondylolysis in young athletes is a safe and practical therapy. Current literature suggests that while conventional repair remains effective, minimally invasive procedures better clinical outcomes. We await further data to conduct a more thorough quantitative analysis of these techniques.

Novel pharmacotherapies in diabetic retinopathy: Current status and what’s in the horizon.

The blood–retinal barrier (BRB) alteration is the hallmark feature of diabetic retinopathy. Vascular endothelial growth factor (VEGF) is a potent vasopermeability factor that has been implicated in the pathogenesis of BRB alteration. Inflammation also plays a crucial role in this process with involvement of several chemokines and cytokines. Multiple anti‑VEGF drugs are widely used as in the treatment of diabetic macular edema (DME) as well as proliferative diabetic retinopathy. Several clinical trials have proved the beneficial effects of these drugs in improvement of vision and prevention of vision loss. However, the response to anti‑VEGF drugs in DME is not complete in a significant number of patients. The effect seems transient in this latter group, and many patients do not show complete resolution of fluid. Potential novel therapies targeting molecules beyond VEGF are being developed and examined in clinical trials.

Advances in Multidetector CT Diagnosis of Pediatric Pulmonary Thromboembolism

Although pediatric pulmonary thromboembolism is historically believed to be rare with relatively little information available in the medical literature regarding its imaging evaluation, it is more common than previously thought. Thus, it is imperative for radiologists to be aware of the most recent advances in its imaging information, particularly multidetector computed tomography (MDCT), the imaging modality of choice in the pediatric population. The overarching goal of this article is to review the most recent updates on MDCT diagnosis of pediatric pulmonary thromboembolism.
