Prevalence and gender difference in depression in primary health care in India: A systematic review and meta-analysis.

Background: Depression contributes to the major burden of mental illness in India. Assessment of burden is essential to develop interventions to address the problem at the primary care level. Materials and Methods: We carried out a systematic review and meta-analysis of studies documenting the prevalence of depression in primary care in India. A wide literature search strategy was developed using keywords and Medical Subject Headings. The literature search was done in MEDLINE (via PubMed), IndMed, and major Indian psychiatric journal websites. The protocol was registered at PROSPERO. Bias assessment was carried out using a Cochrane risk of bias tool. Results: A total of 186 studies were identified after an initial search, of which 17 were included in the final analysis using pre-specified inclusion and exclusion criteria. The aggregate point prevalence of depression at the primary care level of the 17 studies using the random-effect model was 23.0% (95% CI: 16.0-30.0%). Significant heterogeneity was reported among the studies attributed majorly to a variety of study tools for assessing depression. Sub-group analysis revealed the higher aggregated prevalence of depression among females as compared to males at the primary care level. Conclusion: The study provided updated evidence of higher and gender differential burden of depression at the primary care level in India.

Impact of supplementation with iron-folic acid (IFA) and vitamin D3 compared with IFA alone on haemoglobin levels in elderly people with mild-to-moderate anaemia: protocol for the double-blind, randomised, placebo-controlled Iron and vitamin D trial in Elderly Anemia (IDEA).

INTRODUCTION: Anaemia in the elderly is often difficult to treat with iron supplementation alone as prevalence of anaemia of chronic disease (ACD) alone or mixed with iron-deficiency anaemia (IDA) is high in this age group. Hepcidin remains high in ACD, preventing utilisation of iron for heme synthesis. Vitamin D3 has shown hepcidin suppression activity in both in vitro and in vivo studies. As there is no study assessing the effect of iron-folic acid (IFA) with vitamin D3 on haemoglobin levels in the elderly in India, we want to conduct this study to estimate the impact of supplementation of a therapeutic package of IFA and vitamin D3 on haemoglobin levels in the elderly with mild-to-moderate anaemia in comparison with IFA only. The study will also assess the impact of the proposed intervention on ferritin, hepcidin, 25-hydroxyvitamin D, C reactive protein (CRP) and parathyroid hormone (PTH) levels. METHODS AND ANALYSIS: This study is a community-based, double-blind, placebo-controlled, randomised trial. The study will be done in the Kalyani municipality area. Individuals aged ≥60 years with mild-to-moderate anaemia and normal vitamin D3 levels will be randomised into the intervention (IFA and vitamin D3 supplementation) group or the control group (IFA and olive oil as placebo). All medications will be self-administered. Follow-up will be done on a weekly basis for 12 weeks. The calculated sample size is 150 in each arm. Block randomisation will be done. The primary outcome is change in haemoglobin levels from baseline to 12 weeks. Secondary outcome is change in serum ferritin, 25-hydroxyvitamin D, hepcidin, CRP and PTH levels from baseline to 12 weeks. ETHICS AND DISSEMINATION: Ethical approval from the Institutional Ethics Committee of All India Institute of Medical Sciences Kalyani has been obtained (IEC/AIIMS/Kalyani/Meeting/2022/03). Written informed consent will be obtained from each study participant. The trial results will be reported through publication in a reputable journal and disseminated through health talks within the communities. TRIAL REGISTRATION NUMBER: CTRI/2022/05/042775. PROTOCOL VERSION: Version 1.0.

Long-Term Kinetics of SARS-CoV-2 Neutralizing and Anti-Receptor Binding Domain Antibodies among Laboratory-Confirmed COVID-19 Cases in Delhi National Capital Region, India: A Prospective, One-Year Follow-Up Study.

Background: This study was conducted with the objective of measuring the neutralizing and anti-receptor binding domain antibody levels against SARS-CoV-2 among laboratory-confirmed COVID-19 cases and exploring its long-term kinetics over a period of 1 year. Methods: One hundred laboratory-confirmed COVID-19 cases were recruited. Serum samples of the participants were collected within three months from the date of the positive COVID-19 report. The participants were prospectively followed up every three months for symptoms and the collection of blood samples for three additional rounds. The presence of anti-SARS-CoV-2 antibodies (IgA, IgG, and IgM antibodies), anti-receptor binding domain antibodies (anti-RBD), and neutralizing antibodies were measured. Findings: Median plaque reduction neutralization test (PRNT) titers showed a rising trend in the first three rounds of follow-up. The quantitative anti-receptor binding domain ELISA (QRBD) values showed a declining trend in the initial three rounds. However, both the PRNT titers and QRBD values showed significantly higher values for the fourth round of follow-up. Total antibody (WANTAI) levels showed an increasing trend in the initial three rounds (statistically significant). Interpretation: Neutralizing antibodies showed an increasing trend. The anti-receptor binding domain antibodies showed a decreasing trend. Neutralizing antibodies and anti-RBD antibodies persisted in the majority.

Usage of older donors is associated with higher mortality after heart transplantation: A UNOS observational study.

BACKGROUND: Utilization of heart from older donors is variable across centers with uncertain outcomes of recipients. We sought to utilize a national registry to examine the usage and outcomes of heart transplant (HT) recipients from older donors. We also explored the impact of current donor heart allocation scheme on the outcomes of hearts from older donors. METHODS: This observational study utilized the United Network for Organ Sharing database between 2015 and 2023 with donors categorized into age <45 years or ≥45 years and evaluated organ disposition and geographical variation. Thirty-day, 1-, and 3-year mortality, and graft failure rates were compared among recipients as per donor age group. We also evaluated annual trends in HT for each group over the follow-up period. RESULTS: A total of 24,966 adult donors were recovered: 3,742 (15.0%) were ≥45 years; 3,349 (15.6%) adults received heart from such donors with significant geographical variation, and a declining utilization in the transplantation rate in current donor allocation system. Donors with age ≥45 years had higher comorbidities and were allotted with a significantly shorter ischemic time to recipients who were significantly less likely to receive temporary mechanical circulatory support and more likely female. Unadjusted and adjusted, 30-day mortality were similar but 1- and 3-year mortality and graft failure rates were significantly higher in recipients of such donors. Spline analysis suggested a higher 1-year mortality risk at older donor age with risk increasing after age 40 years. CONCLUSIONS: Older donor age was associated with worsened 1- and 3-year mortality and graft failure for heart transplant recipients.

Prevalence and determinants of anemia due to micronutrient deficiencies among children aged 12-59 months in India-Evidence from Comprehensive National Nutrition Survey, 2016-18.

The present study aimed to estimate the prevalence of anemia, and anemia with micronutrient deficiencies (iron/ vitamin B12/ folic acid) and their determinants among children aged 12-59 months in India. Comprehensive National Nutritional Survey (2016-2018) is Asia's largest nutrition survey conducted among 0-19 years aged children in India. We used generalised linear model (modified Poisson) with adjusted prevalence ratio (aPR) to assess the socio-economic and biochemical factors associated with anemia and anemia with micronutrient deficiencies amongst children aged 12 to 59 months. Out of the total of 11,237 children included in the study, 40.5% (95%CI:38·6-42·6) were anemic, 30.0% (95%CI:27·8-32·4) had anemia with micronutrient deficiencies and 60.9% (95%CI:58·2-63·5) had micronutrient deficiencies with or without anemia. Younger age (aPR(95%CI) for one year old: 1.9(1.5-2.4), two year old: 1.8(1.5-2.2), three year old: 1.4(1.2-1.7) compared to four year old children) and lower educational status of the mother (mothers without formal schooling aPR(95%CI):1.4(1.1-1.8); 1-9 standards: 1.4(1.2-1.7)) vs mother educated with high school and above, consumption of less than 100 iron-folic acid tablets during pregnancy (aPR(95%CI):1.3(1.0-1.7) vs consumption of ≥ 180 tablets, any self-reported illness among children within two weeks preceding the interview (aPR(95%CI):1.2(1.1-1.4) vs no-illnesses, iron deficiency (aPR(95%CI):2.2(2.0-2.6)) and zinc deficiency (aPR(95%CI):1.3(1.1-1.4)) were associated with anemia in children. Among anemic, the children from scheduled tribe (aPR(95%CI):1.4(1.1-1.8)) vs other caste categories, and those following unsafe child faeces disposal practices (aPR(95%CI):1.2(1.0-1.4)) vs those who follow safe faeces disposal practices had higher chance of having micronutrient deficiency. One third of children aged 12-59 months had anemia with micronutrient deficiency (iron/ folic acid/ vitamin B12). More than half of children had micronutrient deficiencies irrespective of anemia. Micronutrient deficiencies, antenatal IFA intake, safe hygiene practices need to be strengthened to leave no stone unturned in control of anemia among under-five children in India.

Cell-Mediated Immunity (CMI) for SARS-CoV-2 Infection Among the General Population of North India: A Cross-Sectional Analysis From a Sub-sample of a Large Sero-Epidemiological Study.

Background Cell-mediated immunity (CMI), or specifically T-cell-mediated immunity, is proven to remain largely preserved against the variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), including Omicron. The persistence of cell-mediated immune response in individuals longitudinally followed up for an extended period remains largely unelucidated. To address this, the current study was planned to study whether the effect of cell-mediated immunity persists after an extended period of convalescence or vaccination. Methods Whole blood specimens of 150 selected participants were collected and tested for Anti-SARS-CoV-2 Interferon-gamma (IFN-γ) response. Ex vivo SARS-CoV-2-specific interferon-gamma Enzyme-linked Immunospot (IFN-γ ELISpot) assay was carried out to determine the levels of virus-specific IFN-γ producing cells in individual samples. Findings Out of all the samples tested for anti-SARS-CoV-2 T-cell-mediated IFN-γ response, 78.4% of samples were positive. The median (interquartile range) spots forming units (SFU) per million levels of SARS-CoV-2-specific IFN-γ producing cells of the vaccinated and diagnosed participants was 336 (138-474) while those who were vaccinated but did not have the disease diagnosis was 18 (0-102); the difference between the groups was statistically significant. Since almost all the participants were vaccinated, a similar pattern of significance was observed when the diagnosed and the never-diagnosed participants were compared, irrespective of their vaccination status. Interpretations Cell-mediated immunity against SARS-CoV-2 persisted, irrespective of age and sex of the participant, for more than six months of previous exposure. Participants who had a history of diagnosed COVID-19 infection had better T-cell response compared to those who had never been diagnosed, in spite of being vaccinated.

Non-Lung Solid Organ Transplantation From SARS-CoV-2-Positive Donors to Uninfected Recipients.

BACKGROUND: There is a paucity of evidence on the risk of donor-recipient transmission of the SARS-CoV-2 in solid organ transplant recipients. Initial impressions suggest non-lung solid organs may be safely transplanted from SARS-CoV-2-positive donors without risk of viral transmission. METHODS: We reviewed clinical results of transplants in which SARS-CoV-2-negative recipients received non-lung solid organs from SARS-CoV-2-positive donors at a single transplant center. No prisoners were used in this study, and participants were neither coerced nor paid. The manuscript was created in compliance with the Helsinki Congress and the Declaration of Istanbul. RESULTS: Between June 2021 and January 2023, we transplanted 26 solid organs, including 13 kidneys, 8 livers, 3 hearts, and 1 simultaneous heart and kidney, from 23 SARS-CoV-2-positive donors into 25 SARS-CoV-2 negative recipients. Two of the recipients had a positive SARS-CoV-2 real-time polymerase chain reaction after transplantation, but otherwise, patients had no SARS-CoV-2-related complications, and all patients to date are alive with excellent allograft function. CONCLUSION: Transplantation of non-lung solid organs from SARS-CoV-2-positive donors into uninfected recipients can be safely performed without adverse effects from SARS-CoV-2.

A cross-sectional study on COVID-19 vaccine hesitancy in peri-urban areas in Kanpur, Uttar Pradesh, India.

Vaccination is a potential public health solution for the prevention of infection. It reduces the severity of symptoms in the case of COVID-19. Despite the availability of vaccines, some people are hesitant to be vaccinated. The objectives of this study were to measure the proportion of vaccine hesitancy among the peri-urban population and identify its determinants. An adult population of 303 from two peri-urban areas in the field practice area of the Urban Health Training Center, Rama Medical College, was interviewed from February 22 to March 25, 2021. Epicollect 5 was used for collecting data, and STATA 16 was used for analysis. Multivariable logistic regression was applied to compute the adjusted odds ratio (AOR) (95% confidence interval) to find out the determinants of vaccine hesitancy. The 3Cs model-guided tools were used for data collection and analysis. More than one-fourth (28%) of the participants were vaccine-hesitant, whereas 34.6% had no confidence in the vaccine. Other reasons were complacency (40.6%) and convenience (35.9%). Vaccine hesitancy was significantly associated with gender [AOR=2.40 (1.12-5.16)] and trust in government [AOR=0.18 (0.08-0.45)], but there was no association with age group, political affiliation, or source of information about the vaccine. It is important to build people's trust in vaccines, make them convenient, and resolve the issues that are making them complacent. The health system needs to involve non-governmental organizations to reach out to those for whom there are issues of availability and approach.

Detection and management of HLA sensitization in candidates for adult heart transplantation.

Heart transplantation (HT) remains the preferred therapy for patients with advanced heart failure. However, for sensitized HT candidates who have antibodies to human leukocyte antigens , finding a suitable donor can be challenging and can lead to adverse waitlist outcomes. In recent years, the number of sensitized patients awaiting HT has increased likely due to the use of durable and mechanical circulatory support as well as increasing number of candidates with underlying congenital heart disease. This State-of-the-Art review discusses the assessment of human leukocyte antigens antibodies, potential desensitization strategies including mechanisms of action and specific protocols, the approach to a potential donor including the use of complement-dependent cytotoxicity, flow cytometry, and virtual crossmatches, and peritransplant induction management.

Assessment and management of allosensitization following heart transplant in adults.

Immunological injury to the allograft, specifically by antibodies to de novo donor specific human leukocyte antigen (dnDSA) and antibody mediated injury and rejection are the major limitations to graft survival after heart transplantation (HT). As such, our approach to allosensitization remains limited by the inability of contemporaneous immunoassays to unravel pathogenic potential of dnDSA. Additionally, the role of dnDSA is continuously evaluated with emerging methods to detect rejection. Moreover, the timing and frequency of dnDSA monitoring for early detection and risk mitigation as well as management of dnDSA remain challenging. A strategic approach to dnDSA employs diagnostic assays to determine relevant antibodies in conjunction with clinical presentation and injury/rejection of allograft to tailor therapeutics. In this review, we aim to outline contemporary knowledge involving detection, monitoring and management of dnDSA after HT. Subsequently, we propose a diagnostic and therapeutic approach that may mitigate morbidity and mortality while balancing adverse reactions from pharmacotherapy.

Development and Validation of a Model to Predict Malignancy Within the First Year After Adult Heart Transplantation.

Purpose: Malignancy after heart transplantation is associated with poor outcomes. At present, no prediction model exists for any malignancy within the first year after transplant. Methods: We studied adults who underwent heart transplantation included in the multicenter, national Scientific Registry of Transplant Recipients from January 2000 through April 2021. Possible predictors of malignancy were identified based on their known association with malignancy. Multiple imputations were conducted for missing values using predictive mean matching. A multivariable logistic regression model for predicting malignancy development within the first year after transplant was developed and internally validated via 500 bootstrapped samples to estimate the optimism-corrected measures of model accuracy and performance. Results: Among the 47 212 recipients comprising 16% females, 76% whites, 7% with prior malignancy, and a median age of 56 years; 865 (2.3% of those with non-missing data) developed malignancy within the first year after transplant. Prior malignancy, older age at heart transplantation, white race, and nonischemic heart failure etiology were the strongest predictors of new malignancy. The optimism-corrected model had modest discrimination (C-statistic: 0.70, 95% CI: 0.69-0.72) and good calibration and performance (calibration slope: 0.96; Cox-Snell R2: 0.063), particularly at lower predicted risk. A nomogram for the practicing clinician was developed. Conclusions: Using selection variables previously linked to cutaneous malignancy, our model was modestly predictive of the development of any malignancy in the first year after heart transplantation. Future research could identify factors that may improve malignancy prediction, including incorporation of time-to-event data.

Correction Equation for Hemoglobin Values Obtained Using Point of Care Tests-A Step towards Realistic Anemia Burden Estimates.

Digital hemoglobinometers have been used as point-of-care tests (POCT) to estimate the burden of anemia in community-based studies and national-level surveys in India. As the accuracy of hemoglobin estimated in POCT varies, there is a need for adjustments to the POCT-hemoglobin to ensure they are closer to reality and are comparable. We used data (collected between 2016 and 2020) (N = 1145) from four studies from India: three among pregnant women and 6-59-month-old children from Haryana and the fourth from a national nutritional survey among 1-19-year-old children. We compared the same individuals' POCT-hemoglobin (capillary blood) and automated hematology analyzers (AHA) hemoglobin (venous blood) and developed a predictive linear regression model to obtain the correction equation for POCT-hemoglobin. We analyzed paired data from 1145 participants. The correction equation for obtaining the true hemoglobin value = 3.35 + 0.71 × POCT-hemoglobin using capillary blood (adjusted R2-64.4% and mean squared error -0.841 g/dL). In comparison with the AHA-hemoglobin, the mean difference of POCT-hemoglobin was 0.2 g/dL, while with the predicted Hb obtained from the correction equation it was 0.01 g/dL. The correction equation was the first attempt at deriving the true hemoglobin values from the POCTs. There is a need for multi-country collaborative studies to improve the correction equation by adjusting for factors affecting hemoglobin estimation.

Establishing nomogram of blood pressure for late adolescents in India: Secondary analysis of NFHS-4 data.

Background: Hypertension among adolescents is a public health problem, which is going to become more severe given the current obesity epidemic. There is a scarcity of information on the reference range value for blood pressure (BP) cut-off for adolescents. Aim: We aimed to establish BP distribution in adolescents aged 15-19 years by using the nationally representative National Family Health Survey-4 (NFHS-4) data. Materials and Methods: We analyzed the data of 15,936 boys and 1,04,132 girls aged 15-19 years in the NFHS-4 survey. We took the mean of systolic and diastolic BPs. Height for age z scores for each individual was calculated using the WHO Anthro plus. The sampling weight was taken as provided by the demographic and health surveys (DHS) website. Nomograms of systolic and diastolic BPs were made by calculating their 50th, 90th, and 95th percentiles for each age (in months), gender, and height percentile for age categories. Results: Both systolic and diastolic BPs increased with age and height centiles. The BP was higher in boys than girls. The average annual increase in systolic and diastolic BPs was 2.52 and 1.20 mmHg in boys and 0.50 and 0.46 mmHg in girls, respectively, when adjusted for height centiles. Conclusion: This study provides a BP nomogram that can be generalized to all the Indian population. Research is required for the diagnostic performance of this nomogram for the diagnosis of adolescent hypertension.

Assessment of cardiovascular risk using WHO CVD risk prediction chart with respect to hypertension status among Indian population: A secondary analysis of National Family Health Survey (2015-16).

Background: Hypertension, is a crucial risk factor for the development of cardiovascular disease (CVD). Studies assessing the risk of developing CVD among high-risk groups like hypertensives is limited. Aim: The purpose of this study was to find the distribution of CVD risk with respect to hypertension status among Indian adults. Material and Methods: This was a secondary data analysis of NFHS-4 survey data. The distribution of CVD risk among hypertensive participants using 2019 WHO CVD risk prediction charts was compared with normotensive participants among women aged 40-49 years and men in the age group of 40-54 years. Results: The proportion of hypertension was higher among women who consumed alcohol (31.5%) than those who did not (24.3%). The proportion of hypertensives increased with increasing BMI, with maximum proportion among obese women (37.3%). Among women, majority (95.7%) had low CVD risk (<5%) while 4.2% had 5% to <10% CVD risk, and only 0.1% had >10% risk. Among men, those with low CVD risk (<5%) was 65%, those with 5% to <10% CVD risk was 32.3%, 10% to <20% was 2.7%, and a meagre 0.03% had 20 to <30% risk. Conclusion: In the current study, prevalence of hypertension was seen to be increasing with age and was higher in urban residents than rural among both men and women. Both high blood pressure reading during the survey and self-reported hypertension was found to be higher among richest wealth index category. Although risk was higher among hypertensives, self-reported hypertensives who had their blood pressure controlled, had risk similar to normotensives indicating the importance of management of hypertension.

Anti SARS-CoV 2 IgG antibody response in fully vaccinated Covishield (AZD1222) and Covaxin (BBV-152) recipients: a study done in southern part of West Bengal, India.

Background and Objectives: Vaccination being the only way to reduce mortality from the dreaded COVID-19 disease, the vaccine was introduced in India as per the advice of the National Expert Group on January 16, 2021. Duration of immune response elicited by the vaccines has always been a matter of content. With new variants emerging every other day, the study was done to look for the antibody response in vaccine recipients post second dose of vaccination. Materials and Methods: A longitudinal observational study was conducted from August 2021 to February 2022 in fully vaccinated individuals who took either Covishield (AZD1222) or Covaxin (BBV-152). Blood was collected from the individuals at 12-16 weeks post-vaccination to look for IgG antibody response against S1 spike protein of SARS-CoV2 by ELISA. Follow-up was done at 32 weeks post the second dose in individuals who had received Covishield. Results: Among 176 individuals, IgG antibody against S1 spike protein was found to be positive in 89.7% (158). Covishield recipients showed higher antibody response (99.1%) as compared to Covaxin recipients (71%). Antibody response was higher in males, individuals less than 50 years, and non-comorbid individuals. Of 38 Covishield recipients, IgG antibody response was positive in 28 (73.6%) individuals when followed up at 32 weeks post the second vaccination dose. Conclusion: The study gives us input with regard to the long-term antibody kinetics of both vaccines. The study has a follow-up plan to co-relate the antibody response to the neutralization test.

Community practices in COVID-19 outbreak in rural Ballabgarh, Haryana - A mixed methods study.

Background: More than 43 million cases and 5.2 lakhs death have occurred due to COVID-19 in India. Approximately 1 lakh people (cumulative) have been infected by COVID-19 in Faridabad district alone as of 4 April 2022. To understand the effects of COVID-19 on community practices this study was conducted. Methods: A community-based cross-sectional study was conducted in Intensive Field Practice Area of Comprehensive Rural health Services Project (CRHSP), Ballabgarh, Haryana. Five hundred participants (≥18 years) were selected by using simple random sampling from Health Management Information System (HMIS) maintained at Centre for Community Medicine, AIIMS, New Delhi. Participants were informed regarding study and consent was taken. A semi-structured interview schedule was administered. Results: Study participants included 500 adults (52.2% Male). Mean age (S.D.) of participants were 39.1 (14.9) years. Almost all participants started practicing hand sanitisation (496, 99.2%), avoiding crowd (488, 97.6%), and covering face with cloth/handkerchief (459, 91.8%). More than 80% (428, 85.6%) started using mask, and following cough etiquettes (405, 81.0%). More than three-fourth (389, 77.8%) participants were very unsatisfied with lockdown. Majority faced financial difficulties (322, 64.4%), followed by difficulty in their entertainment/recreational activity (158, 31.6%), difficulty in acquiring ration/food items (87, 17.4%) and mental stress (46, 9.2%) during lockdown. Conclusions: Rural community of Ballabgarh showed positive practices with respect to prevention of COVID-19. Financial distress and job loss due to lockdown were widely reported from the rural community. Majority of the community was displeased with lockdown as intervention for COVID-19.

Evaluation of a Flexible Weight and Height Interaction Versus Body Mass Index for Mortality Prediction After Adult Heart Transplant.

OBJECTIVES: Body mass index (calculated as kilograms body weight divided by the square of heightin meters) is a known predictor of mortality after adult heart transplant but has limitations.We investigated whether inclusion of an explicit weight-height interaction effect improves prediction of mortality after heart transplant compared with body mass index. METHODS AND RESULTS: We included a cohort of 46424 adults who had undergone heart transplant as documented in the United Network for Organ Sharing database. Risk-adjusted prediction models for 1-year and 5-year mortality were constructed, one with the flexible weight-height interaction and the other with the body mass index. Overall model performance (R2) and discrimination (the Harrell concordance probability C index and the Somers Dxy rank correlation) were calculated. Compared with the body mass index model, the weight-height model had slightly improved overall performance (R2, 0.316 vs 0.313) and 1-year mortality discrimination (optimism- corrected Harrell C, 0.642 vs 0.640; Somers Dxy, 0.284 vs 0.281). Compared with the body mass index model, the weight-height model had improved overall performance (R2, 0.232 vs 0.224) and similar discrimination (optimism-corrected Harrell C, 0.600 vs 0.599; Somers Dxy, 0.200 vs 0.197) for 5-year mortality. CONCLUSIONS: Allowance for a flexible relationship between height and weight did not appreciably improve mortality prediction after heart transplant, versus body mass index, although additionalresearch is warranted.
