Impact of Living Donor Liver Transplantation on COVID-19 Clinical Outcomes from a Quaternary Care Centre in Delhi

Background and AimsThe anticipated fear of serious outcomes in coronavirus infected liver transplant recipients led to disruption of transplant services globally. The aim of our study was to analyze COVID-19 severity in transplant recipients and to compare the difference of COVID-19 clinical outcomes in early (<1 year) vs. late (>1 year) post-transplant period.Methods41 post-living donor liver transplant recipients with COVID-19 infection were studied retrospectively from 1st April 2020 to 28th February 2021.ResultsThe median age was 49.00 years with a male preponderance (80.49%). Fifteen patients had infection within 1 year of transplant and 26 were infected after 1 year of transplant. The overall median interval between transplantation and COVID-19 diagnosis was 816.00 days. Fever and malaise were the common presenting symptoms. The most common associated comorbidities were diabetes mellitus (65.85%) and hypertension (46.34%). The severity of illness was mild in 28 (68.29%), moderate in 4 (9.76%), severe in 6 (14.63%) and critical in 3 (7.32%). To identify associated risk factors, we divided our patients into less severe and more severe groups. Except for lymphopenia, there was no worsening of total bilirubin, transaminases, alkaline phosphatase, and gamma-glutamyl transferase in the more severe group. Eight (19.51%) patients required intensive care unit admission and three (7.32%) died, while none suffered graft rejection. In recipients with early vs. late post-transplant COVID-19 infection, there were similar outcomes in terms of severity of COVID-19 illness, intensive care unit care need, requirement of respiratory support, and death.ConclusionLiving donor liver transplantation can be performed during the COVID-19 pandemic without the fear of poor recipient outcome in cases of unfortunate contraction of severe acute respiratory syndrome coronavirus-2.     

Post-Mastectomy Breast Reconstruction: A History in Evolution

Although the need for mastectomy has been evident for many years, postmastectomy reconstruction has been recognized as an achievable outcome for only a little over a century. A review of the evolution of both autologous and prosthetic options for reconstruction was undertaken. The earliest attempts at reconstruction used autologous techniques that were either unsuccessful, not reproducible, or were associated with significant morbidity. Prosthetic techniques became sought after, with silicone prostheses widely used until concerns about potential adverse effects led to the investigation of alternate options. With these concerns shown to be unfounded, silicone and saline prostheses evolved with successive generations of implants. Concurrent advances in reconstructive surgery led to a revival in autologous techniques for breast reconstruction, with microsurgical free-tissue transfer potentiating a new range of potential donor sites. The abdominal wall became the donor site of choice, and with the advent of perforator flaps, morbidity associated with flap harvest was minimized. In cases where the abdominal wall is unsuitable, flaps such as the superior and inferior gluteal artery perforator flaps, the musculocutaneous gracilis flap, and the “stacked” deep inferior epigastric artery perforator flap are frequently used options. The development of minimally invasive techniques for implant placement and flap harvest, such as endoscopy, continue to evolve, and research in tissue engineering offers a vision for a future without the need for a donor site.     

Quantitative analysis of myocardial inflammation by flow cytometry in murine autoimmune myocarditis: correlation with cardiac function

Inflammation has been increasingly recognized as an important pathological component of heart failure. Existing methods of assessing myocardial infiltrate are labor-intensive and provide data that are difficult to quantify and not representative of the whole heart. As a result, little effort has been made to systematically assess the components of myocardial inflammation. We established an alternative method of quantitative assessment of myocardial inflammation by flow cytometry after enzymatic digestion of hearts to characterize the infiltrate and study the association between inflammation and cardiac function in murine experimental autoimmune myocarditis. The severity of acute myocarditis uniquely correlated with the proportion of neutrophils, but not T cells, B cells, or macrophages. Both acute and chronic phases were characterized by the presence of CD44high (activated) T cells in the heart, whereas T cells trafficking through normal hearts exhibited CD44low phenotype. During the chronic phase, the proportion of CD4+ T cells was associated with increased left-ventricular volumes and deterioration of systolic function, the hallmarks of dilated cardiomyopathy. We conclude that flow cytometry on uniformly digested mouse hearts provides sensitive and reproducible assessment of myocardial infiltrate and can be used to dissect out the specific role of individual immune components from the overall inflammatory response in the heart.     

Genetic counseling in adult polycystic kidney disease

We evaluated 22 patients with end-stage renal disease (ESRD) due to adult polycystic kidney disease (APKD) to assess their knowledge of the hereditary nature of the condition and to determine whether they received adequate genetic counseling. Patients were evaluated by means of a questionnaire and a review of their medical records. Only 5 of 22 (23%) knew their disorder was hereditary at the time of diagnosis, and in only 4 (18%) was genetic counseling suggested. In no instance had proband and spouse received genetic counseling together. Diagnostic studies of children at risk were rarely suggested. We also evaluated the children of 9 probands for APKD. Of 26 children evaluated, 17 had APKD (65%). Sixteen had no children at the time of testing. All but two of the 26 were less than 25 years old. Of the probands' children over 15 years of age, 55% knew the name of the condition in the family but only 9% knew they should be tested. Our study demonstrated inadequacy of genetic counseling and follow-up in this group of patients; we suggest that referral for counseling become a routine part of their management. Early diagnosis and effective counseling has the potential benefit for the individuals of making rational reproductive decisions appropriate for their situation. Counseling may have to be repeated during the course of the patients' disease, as their perception of risk may change with time. With advances in dialysis and transplantation, ESRD may not be as devastating in years to come as it is now.     

Comparison of outcomes of hand‐assisted laparoscopic to open donor nephrectomy for pediatric recipients

The purpose of this study is to compare the outcome of pediatric recipients of kidneys procured using a hand‐assisted laparoscopic (HALDN group) to an open technique (ODN group). Twenty‐eight patients ≤18 yr old (HALDN group) were compared with 17 patients (ODN group). The serum creatinine for HALDN and ODN groups at discharge were 0.93 ± 0.48 and 0.94 ± 0.54 mg/dL (p = 0.917), respectively. The serum creatinine for HALDN and ODN groups at six and 12 months was 1.01 ± 0.44 and 1.11 ± 0.55, and 1.04 ± 0.52 and 1.14 ± 0.46 mg/dL (p = 0.516, p = 0.554), respectively. The eGFR for HALDN and ODN groups at discharge was 108.66 ± 37.23 and 106.1 ± 50.55 mL/min/1.73 m² (p = 0.845), respectively. The eGFR for HALDN and ODN groups at six and 12 months was 97.77 ± 28.25 and 81.73 ± 27.46, and 94.56 ± 28.3 and 85.74 ± 30.1 mL/min/1.73 m2 (p = 0.085, p = 0.344), respectively. The patient and graft survival for both groups were 100% at 12 months post‐transplant. In conclusion, the short‐term outcome of recipients of kidneys procured via HALDN is comparable to that of kidneys procured via ODN in pediatric patients.     

Evaluation of the safety of short-acting nifedipine in children with hypertension

Concerns regarding the safety of nifedipine emerged in 1995 with the report of an increased risk of myocardial infarction associated with adult patients receiving short-acting calcium channel blockers. There have been few case reports of adverse events in children. The purpose of this study is to investigate the effect on blood pressure (BP) and the incidence of adverse events associated with nifedipine in our pediatric population. We conducted a retrospective chart review of pediatric patients who received nifedipine. We recorded the dose administered, all BP measurements and all adverse events reported within six hours of a nifedipine dose regardless of the likelihood that those events were related to the nifedipine dose. 1,746 doses of nifedipine in 166 pediatric patients were reviewed. Systolic BP decreased by a mean of 17% and a maximum of 63%. Diastolic BP decreased by a mean of 28% and a maximum of 89%. Adverse events included: a) change in neurologic status, six cases; b) hypotension, two cases; c) oxygen desaturation, 16 cases. Neurologic events occurred in 33% of patients with acute CNS injury and 3.6% of all patients. Short-acting nifedipine is an important and effective oral antihypertensive agent which can be safely used for the treatment of hypertensive emergencies in children. It should be used with caution in children with acute CNS injury. Received: 2 January 2001 / Revised: 25 July 2001 / Accepted: 25 July 2001     

Profile of anganwadi workers and their knowledge about ICDS

Profile of 96 anganwadi workers of Inderpuri project area in Delhi and their knowledge about ICDS was assessed through a questionnaire. 92.71 percent AWW were trained, and only 17.71 perceent lived and worked in the small locality. The number of children under 2 they would expect in an anganwadi was known to only one (1.04%) and the number of pregnant and lactating mother to only 3.12 percent. Majority 92.71 percent could not tell full form of ICDS. Most of them (90.62%) could not enumerate all the services being provided and none could list out their job responsibilities. It is recommended that the existing training of AWWs needs to be evaluated and their continuous education strengthened.
