The study population consisted of greater Worcester residents hospitalized with a discharge diagnosis of AMI at all teaching and community hospitals in the Worcester metropolitan area during the 15 individual study years of 1975 (n=781), 1978 (n=845), 1981 (n=998), 1984 (n=714), 1986 (n=765), 1988 (n=659), 1990 (n=766),1991 (n=848), 1993 (n=953), 1995 (n=949), 1997 (n=1,059), 1999 (n=1,027), 2001 (n=1,239), 2003 (n=1,157), and 2005 (n=903). There were originally 16 hospitals included in this population-based investigation but there are presently 11 due to hospital closures or conversion to chronic care or rehabilitation facilities. Potentially eligible patients were identified through the review of computerized hospital databases of patients with International Classification of Disease discharge diagnoses consistent with the possible presence of AMI (e.g., AMI, unstable angina). The medical records of all potentially eligible patients, who had to be residents of the Worcester metropolitan area since this study is population-based, were reviewed in a standardized manner and the diagnosis of AMI was confirmed according to pre-established criteria that have been previously described (15 (link)-17 (link)).
Cardiogenic shock was defined as a systolic blood pressure of less than 80 mm Hg in the absence of hypovolemia and associated with cyanosis, cold extremities, changes in mental status, persistent oliguria, or congestive heart failure (6 (link),7 (link)). The definition of cardiogenic shock remained the same during all periods studied. This disorder was defined so that patients with classic signs and symptoms of this clinical syndrome would be included.

The medical charts of 356 typical HFRS patients who were treated in the Center for Infectious Diseases, Tangdu Hospital, between January 2008 and August 2012 were selected randomly and reviewed. The diagnosis of HFRS was made based upon the detection of specific IgM and IgG antibodies to HTNV in acute phase serum specimens by enzyme-linked immunosorbent assay (ELISA).
Based upon clinical classification of HFRS [15 ], the patients were classified into four types: (1) mild, defined as patients who had kidney injury without oliguria and hypotension; (2) moderate, defined as patients who had uremia, effusion (bulbar conjunctiva), hypotension, hemorrhage (skin and mucous membranes), and AKI with typical oliguria; (3) severe, defined as patients who had severe uremia, effusion (bulbar conjunctiva and either peritoneum or pleura), hemorrhage (skin and mucous membranes), hypotension and AKI with oliguria (urine output of 50–500 mL/day) for ≤ 5 days or anuria (urine output of < 100 mL/day) for ≤ 2 days; (4) critical, defined as patients who usually had one or more of the following complications compared with the severe patients: refractory shock (≥ 2 days), visceral hemorrhage, heart failure, pulmonary edema, brain edema, severe secondary infection, and severe AKI with oliguria (urine output of 50–500 mL/day) for > 5 days or anuria (urine output of < 100 mL/day) for > 2 days. Commonly, the so-called acute stage of the disease is defined as the period of febrile, hypotensive and oliguric phases. Overall, 75 cases were classified as critical type and were enrolled in this study. Furthermore, the outcome was defined as death or survival during the interval of being in hospital and after discharge with following up.

Medical records of 291 patients were collected from January 1, 2003 to April 30, 2016. Of these, 28 underwent more than one CRRT treatment run. Final analysis was done by removing duplicates and leaving only the longest CRRT run.
During the study period, patients undergoing CRRT were included and grouped as before SCT (group A) and after SCT (group B). Group A included patients treated from March 2003 to July 2008 and group B those from August 2008 to April 2016. Before SCT, pediatric CRRT was run by occasional operators, but after the SCT began, ICU nurses joined and began to work as the member of SCT. Double-lumen catheters ranging between 6.5 and 13.5 F in diameter (Gambro Healthcare, Lakewood, CO, USA) were inserted into the central veins depending on the child’s age and weight. Polyarylethersulfone hollow-fiber hemofilters (PAES; the Prismaflex® HF20, Gambro Lundia AB, Lund, Sweden) and polyacrilonytrile hollow-fiber hemofilters (① AN69® membrane before the year 2010; the Prismaflex® M-10/60/100, Gambro Lundia AB, Lund, Sweden; ② AN69® ST membrane since the year 2010; the Prismaflex® ST-60/100, Gambro Lundia AB, Lund, Sweden) were used in all patients, depending on the patient’s weight. HF-20 or M-10 were used in children weighing less than 10 kg; ST-60 or M-60 were used in patients weighing 10–20 kg, and ST-100 or M-100 were used in children weighing more than 20 kg. Commercially prepared bicarbonate-buffered hemofiltration replacement fluid (Hemosol B0; Gambro Healthcare, Seoul, Korea; potassium free), was used as a dialysate and replacement fluid. Potassium chloride (KCl) was added if the patient has a risk of hypokalemia (20 mEq KCl mix in the 5L Hemozol® when serum potassium level ranged from 3.6 to 4.5 mEg/L and 40 mEq KCl mix in the 5L Hemozol® when serum potassium level lowered than 3.6 mEg/L). The blood flow rate was set as 5 mL/kg/min [18 (link)]. The predilution replacement fluid rate or dialysate rate was set at a rate of 2000 mL/1.73 m2/hour [18 (link)]. The mode of CRRT was selected from one of the following, depending on the patient’s status of solute imbalance: continuous veno-venous hemofiltration (CVVH), continuous veno-venous hemodialysis (CVVHD), and continuous veno-venous hemodiafiltration (CVVHDF). These were determined by the pediatric nephrologist and pediatric intensivist through in-depth discussion.
The time to initiate CRRT was decided by the pediatric intensivist, depending on each patient’s clinical condition, such as anuria, oliguria (<0.5 mL/kg/hour), or positive fluid balance, regardless of administration of high doses of diuretics (furosemide more than 1 mg/kg/hour). Anticoagulation was not administered during CRRT initiation; however, our protocol establishes that if the filter was blocked within 12 hours of CRRT initiation, anticoagulation agents such as continuous heparin or nafamostat mesilate infusion via the pre-blood pump port were used. The percentage of fluid overload at CRRT initiation (%FO) was calculated using the following formula [20 (link)]:
At the initiation of CRRT, the following data were obtained for all patients: sex, age, diagnosis, underlying patient conditions, blood flow rate, use of inotropic agents, anticoagulants, and hours to starting CRRT.

Study design 
We performed a retrospective analysis utilizing SUNY Upstate University Hospital data from January 2016 to March 2022 to assess transplant outcomes and biopsies. The data were collected from the electronic medical record system (EPIC). Inclusion required patients who received a renal transplant and adult recipients (> 16 years old). Simultaneous kidney-pancreas, other multiorgan transplant recipients, pediatrics (<16 years old), and mortality in 30 days were excluded. A renal biopsy was done at the center by the transplant surgeon, and the result was reported by the pathologist at SUNY Upstate Medical University’s pathology department. The study population was divided into two subgroups: non-protocol biopsies and protocol biopsies within the 12 months post-transplant. The non-protocol biopsy cases were patients who presented with an alarm sign for possible rejection, such as an increase in serum creatinine above the patient’s baseline value, unexplained fever, edema, hypertension, oliguria, anuria, and proteinuria unrelated to glomerulonephritis with the first 12 months post-kidney transplant. Protocol biopsies were within the first 12 months post-transplant in patients with stable serum creatinine and without any clinical manifestation suspected of kidney rejection. The baseline characteristics of the groups of interest were compared. The graft rejection types were reported by the pathologist as antibody-mediated rejection (ABMR), T-cell mediated rejection (TCMR), borderline rejection (BR-L), and mixed rejection with both antibody-mediated and T-cell mediated rejection at the same time. The Banff 2013 rejection criteria and components were implanted to assess and compare the histopathological features of rejection in each group as the protocol [17 ].
Outcome definitions
The primary objective was to assess the protocol biopsies results, compare the outcomes with the kidney recipients that did not have the protocol biopsies as part of their post-transplant screening, and compare the acute rejection rate and graft failure. The secondary objective was to assess how protocol biopsies could improve the patient and graft survival rates.
Statistical analyses
The primary analyses measured the baseline characteristics in the groups of interest. The t-test and analysis of variance (ANOVA) performed univariate analysis for continuous variables, chi-square test for categorical variables, and Kaplan-Meier curves to assess patient and graft survival rates. Categorical data were summarized as proportions and percentages, and continuous data were summarized as means and standard deviations. A P-value of <0.05 was considered significant, and a P-value of < 0.1 was considered a trend.

We considered serum creatinine at the last medical appointment before hospital admission for HSCT to be baseline serum creatinine. Baseline glomerular filtration rate was estimated according to CKD-EPI equation [10 (link)], using baseline serum creatinine.
AKI diagnosis was made based on daily values of serum creatinine and 6-h urinary output since the time of hospital admission for HSCT until hospital discharge, as well as all other hospital admissions or weekly evaluation in outpatient clinic in the first 100 d after HSCT. AKI was defined by KDIGO criteria [7 ] (any of the following: Increase in serum creatinine by ≥0.3 mg/dl (≥26.5 µmol/l) within 48 h; or increase in serum creatinine to ≥1.5 times baseline, which is known or presumed to have occurred within the prior 7 d; or urinary output <0.5 ml/kg/h for 6 h). Stage of AKI followed KDIGO classification considering the worst serum creatinine value and/or longest period of urinary volume reduction during hospital stay for HSCT. Moderate to severe AKI was defined as AKI stage 2 and AKI stage 3.
CKD was defined as a persistent decrease in eGFR to below 60 ml/min/1.73 m2, according to the definition of KDIGO [11 (link)].
The hematopoietic cell transplantation – specific comorbidity index (HCT-CI) [12 (link)] was calculated according to the latest validated version considering patients comorbidities. Shock was considered when patients presented with cardiac frequency >90 bpm, systolic blood pressure <90 mmHg, and at least one lactate determination >2 mmol/l or 22 mg/dl.
Nephrotoxic drugs included gentamicin, amikacin, vancomycin, amphotericin B, and foscarnet.

We identified ten consecutive patients who developed TMA between 2005-2020, while receiving treatment with carfilzomib at the University of Athens in Greece or at the Dana Farber Cancer Institute in the United States. A clinical diagnosis of carfilzomib-induced TMA was made based on the fulfillment of the following criteria: active carfilzomib treatment; new onset of microangiopathic hemolytic anemia with decreased haptoglobin, thrombocytopenia and evidence of schistocytes on peripheral blood smear; oliguric, acute kidney injury network (AKI), AKIN ≥I (defined as a rise in serum creatinine relative to baseline of at least 1.5 times or 0.3 mg/dl and reduced urine output to less than 0.5 mL/kg/h within 48 h); in the absence of an acute infectious process, decreased ADAMTS13 activity and positive Coombs test. The control group included 10 patients treated with carfilzomib at the same institutions during 2015–2021 and who did not develop TMA. Controls were matched to the patient cohort based on age, gender, carfilzomib dose/duration and use/type of anti-platelet/anticoagulant agent. All subjects in the study were enrolled in IRB-approved protocols at the respective institutions. This study was conducted in accordance with the Declaration of Helsinki.

A cross-sectional survey of increasingly complex potential deceased kidney donor
cases was developed by one of the study investigators with input from the study
steering committee. The survey was translated into French by a professional
translator with the French version subsequently corrected by a French-speaking
transplant nephrologist.
Survey questions are presented in Supplemental Table 1. There were 3 sections examining different
kidney donor offer scenarios (Section 1: 8 questions; Section 2: 8 questions;
Section 3: 16 questions) and respondents were asked whether they would accept or
decline a hypothetical donor presented in the question stem, assuming there was
a suitable recipient. Within each Section, donor cases were sequentially adapted
to become increasingly complex (eg, in Section 1, a 40-year-old neurological
determination of death (NDD) donor with normal renal function (Profile 1a), then
a 40-year-old NDD donor with acute kidney injury (AKI) (Profile 2a), then a
40-year-old NDD donor with severe AKI but reassuring biopsy findings (3a), then
a 40-year-old NDD donor with severe AKI and no biopsy (4a)). Within Section 1
this was then repeated, except with a donation after cardiac death (DCD) donor
(Profiles 1b-4b). Respondents were presented the base cases for each donor
scenario in each Section (Profiles 1a, b, c & d, Supplemental Table 1) but using skip logic and conditional
branching they were only provided the next level of donor complexity within that
Section if they accepted the donor in the prior scenario. Given the graduated
increased complexity of each donor case, it was assumed that when a respondent
declined a base donor in a particular scenario, they would also decline all
downstream adaptations to that base stem. For example, if a respondent declined
a 40-year-old NDD donor with normal kidney function (Section 1, Profile 1a),
they would automatically be considered as declining the more complex and
higher-risk donors from Section 1, Profile 2a (the same donor now with
non-oliguric AKI) and 3a (the same donor now with oliguric and
dialysis-dependent AKI). When a respondent first declined a potential deceased
donor, they were asked to select all reasons for their decision, categorized as
Donor age, NDD vs. DCD, kidney function, severity of AKI event, biopsy results,
other.
In Sections 1 and 2, base donor cases were primarily stratified by mode of death
(NDD or DCD) and donor age (40 or 60 years), with respondents being prompted to
indicate if either of these factors influenced their decisions. Conversely, in
Section 3, donor cases were stratified by mode of death and donor sex rather
than age (fixed at 65 years). It should be noted that the creatinine values
varied between profiles on the basis of sex which resulted in a higher estimated
glomerular filtration rate (eGFR) for the female recipient (eGFR by
CKD-Epi2021 101 mL/min/1.73 m2 for the 65-year-old
female with admission creatinine 50 umol/L versus 77 mL/min/1.73 m2for the 65-year-old male with admission creatinine 95 umol/L).
