Abstract
OBJECTIVE The American Academy of Pediatrics recommends that pediatric providers screen families for food insecurity and connect them to appropriate resources. However, it is unclear how clinics can best provide families with resources consistent with their needs and preferences. In this study, we elicited caregiver preferences for clinic-based food assistance. METHODS We conducted a cross-sectional discrete choice experiment in which caregivers at 2 pediatric primary care clinics were asked to choose between hypothetical food programs. Programs varied across 4 categories: 1) resources provided (eg, food delivery, food in clinic, assistance enrolling in benefits); 2) support staff providing resources (eg, social worker, community health worker, physician, or nurse); 3) outreach modality (eg, phone, email, text); and 4) outreach frequency. Multinomial logistic regression was used to assess caregiver preferences within each category and the relative importance of each category to caregiver decisions. RESULTS We surveyed 142 caregivers who were predominantly Black (87%) and Medicaid-insured (90%). Caregiver preferences for food programs were most strongly influenced by the food resources provided. Caregivers preferred food delivery over other forms of food supports, such as food provided in clinic. They preferred assistance from a benefits enrollment specialist, community health worker, or social worker to assistance from a physician or nurse. CONCLUSIONS Pediatric clinics serving families at risk of food insecurity should use caregiver preferences to inform the design of family-centered interventions. Clinics should consider connecting caregivers with food delivery programs, and pediatric payors should adopt reimbursement models that support multidisciplinary team-based care to address food insecurity.

Abstract
OBJECTIVE Parents of pediatric patients are key stakeholders in the design and implementation of health-related social needs (HRSN) screening programs. Yet, there is little research exploring their perspectives on the documentation and sharing of HRSN data. We aimed to examine parents' preferences regarding how HRSN data are documented and shared. METHODS We conducted semi-structured interviews with parents of hospitalized children participating in an HRSN screening program at a quaternary care children's hospital. Interviews were coded using an inductive and deductive approach to identify emergent themes. RESULTS The 20 interviewed parents were uniformly female with 55% identifying as Black or African American and 20% identifying as Hispanic or Latino. Parents expressed comfort with electronic health record documentation of HRSN data and the use of International Classification of Diseases, 10th Revision Z codes as long as this information was used to provide families with meaningful support. Most parents viewed social workers and medical teams as the most appropriate recipients of HRSN data. Few parents felt comfortable with HRSN data being shared with payors. Parents desired transparency around HRSN data sharing. Many expressed concerns that documentation and sharing of HRSN data could lead to unwanted or unsafe disclosures or result in child welfare referrals. CONCLUSIONS Parents expressed comfort with HRSN documentation and sharing with health care providers, but requested that providers be transparent and respect parental preferences regarding data sharing to mitigate potential harms. When implementing HRSN support programs, health systems and payors should prioritize transparency around documentation and data sharing with families.

Abstract
BACKGROUND AND OBJECTIVE In 2019, Pennsylvania launched a Children's Development Account (CDA) program that invests $100 in an education savings account for every child born in the state. However, as of 2021, only 10.6% of families claimed the investment. Low-income communities may stand to benefit most from educational investments, but few studies have assessed barriers and facilitators of uptake in these communities. We sought to examine low-income caregivers' perceptions of and barriers and facilitators to participation in a statewide CDA program and their receptivity to clinic-based financial counseling through a medical financial partnership. METHODS We surveyed 100 caregivers of Medicaid-insured children from 2 primary care practices serving a predominantly low-income community. From these 100, we purposively sampled 30 caregivers for follow-up interviews. RESULTS The 100 survey participants were predominantly female (83%), Black or African American (92%), and non-Hispanic or Latino (93%). Twenty-nine percent of survey participants were aware of the CDA program, 4% had enrolled, and 64% were interested in clinic-based financial counseling. In interviews, caregivers identified several barriers to and facilitators of engagement in the CDA program. They also identified several strategies to boost engagement, including simplifying registration, providing additional and personalized program information, expanding the investment amount, and providing clinic- and community-based outreach. CONCLUSIONS Low-income caregivers identified several barriers to enrollment in a statewide CDA program and strategies to boost enrollment, including clinic-based financial counseling. Future research should examine the effectiveness, cost-effectiveness, and long-term financial and health consequences of clinic-based financial services for low-income families.

Abstract
Systematic and timely documentation of triggered (i.e. event) landslides is fundamental to build extensive datasets worldwide that may help define and/or validate trends in response to climate change. More in general, preparation of landslide inventories is a crucial activity since it provides the basic data for any subsequent analysis. In this work we present an event landslide inventory map (E-LIM) that was prepared through a systematic reconnaissance field survey in about 1 month after an extreme rainfall event hit an area of about 5000 km2 in the Marche-Umbria regions (central Italy). The inventory reports evidence of 1687 triggered landslides in an area of ~550 km2. All slope failures were classified according to type of movement and involved material, and documented with field pictures, wherever possible. The database of the inventory described in this paper as well as the collection of selected field pictures associated with each feature is publicly available at figshare.

Abstract
BACKGROUND AND PURPOSE Preterm infants are at risk for overt and silent CNS injury, with developmental consequences that are difficult to predict. The novel Specific Test of Early Infant Motor Performance, administered in preterm infants at term age, is indicative of later developmental gross motor and cognitive scores at 12 months. Here, we assessed whether functional performance on this early assessment correlates with CNS integrity via MR spectroscopy or diffusional kurtosis imaging and whether these quantitative neuroimaging methods improve predictions for future 12-month developmental scores. MATERIALS AND METHODS MR spectroscopy and quantitative diffusion MR imaging data were acquired in preterm infants (n = 16) at term. Testing was performed at term and 3 months using the Specific Test of Early Infant Motor Performance and the Bayley Scales of Infant and Toddler Development, Third Edition, at 12 months. We modeled the relationship of MR spectroscopy and diffusion MR imaging data with both test scores via multiple linear regression. RESULTS MR spectroscopy NAA ratios at a TE of 270 ms in the frontal WM and basal ganglia and kurtosis metrics in major WM tracts correlated strongly with total Specific Test of Early Infant Motor Performance scores. The addition of MR spectroscopy and diffusion separately improved the functional predictions of 12-month outcomes. CONCLUSIONS Microstructural integrity of the major WM tracts and metabolism in the basal ganglia and frontal WM strongly correlate with early developmental performance, suggesting that the Specific Test of Early Infant Motor Performance reflects CNS integrity after preterm birth. This study demonstrates that combining quantitative neuroimaging and early functional movement improves the prediction of 12-month outcomes in premature infants.

rescan 2Decho, 3Decho, 1.5T Siemens CMR (Cine imaging and Displacement encoding with stimulated echoes [DENSE]), 3T Siemens CMR (Cine Imaging and DENSE) and 3T Philips CMR (Tagging and Fast strain-encoding [fSENC]) imaging. Strain was quantified for 2Decho (EchoPAC), 3Decho (TomTec), Feature tracking (FT) for cine imaging (CircleCVI), CIM (University of Auckland) for DENSE and Tag, and Myostrain (Myocardial solutions) for fSENC.
Results
20(6F) volunteers, mean age 33 ± 7 years, mean LVEF 62 ± 4%. All GLS and GCS methods had excellent inter-study agreement (ICC > 0.75) with coefficient of variation (CoV) between 4-8% (Table 1). Median and IQR are presented in Figure 1.
Friedman’s test revealed statistically significant inter-method differences for GLS (χ2 = 66.4,p < 0.0001) and GCS (χ2 = 50.9,p < 0.0001). Post hoc analysis using Dunn’s test with Bonferroni correction demonstrated significant differences:
-GLS: 2Decho vs DENSE 1.5T (p = 0.001) and Myostrain 3T (p = 0.0116); 3Decho vs FT 3T (p = 0.049) and DENSE 1.5T (p < 0.0001); FT 1.5T vs DENSE 1.5T (p = 0.001) and Myostrain 3T (p = 0.01); FT 3T vs Myostrain 3T (p < 0.0001); DENSE 1.5T vs Tag 3T (p = 0.0008) and Myostrain 3T (p < 0.0001); Tag 3T vs Myostrain (p = 0.02).
-GCS: 3Decho vs DENSE 1.5T (P = 0.0005), FT 1.5T (p < 0.001), FT 3T (P < 0.001) and Myostrain (p = 0.003); FT 1.5T vs Tag 3T (p = 0.001), FT 3T vs Myostrain 3T (p = 0.04).
Conclusion
There is excellent interstudy agreement for GLS and GCS methods. However, there are important inter-method differences in absolute values, that need to be considered for clinical application as a surveillance method and longitudinal studies.

Introduction – Imaging derived left ventricular ejection fraction (LVEF) has an important role to guide initiation of medical therapy and device insertion in patients with heart failure and reduced ejection fraction (HFrEF). Previous studies have reported the correlation and agreement of LVEF in various patient populations, but sparse evidence exists on patients with heart failure referred for Cardiac Resynchronisation Therapy (CRT) using 2D and 3D echocardiography (2DE & 3DE) and cardiovascular magnetic resonance (CMR).
Objectives – To determine the correlation and agreement of LVEF as determined by 2DE, 3DE and CMR in a cohort of HF patients referred for assessment of CRT.
Methods – Patients with suspected HFrEF referred for assessment for CRT therapy were included in this single centre study. Patients underwent 2DE, 3DE and CMR to derive LVEF, LVESV and LVEDV. Correlation was determined with Pearson’s correlation, agreement with Bland-Altman analysis and Cohen’s kappa analysis for agreement using a dichotomous cut off of LVEF ≤35% as a threshold for CRT insertion (Ponikowski, 2016).
Results - 55 patients (mean age 71 ± 9.2, 76% male) were included. The mean LVEF for 2DE, 3DE, CMR and were 32.4 ± 8.6, 32.1 ± 9.6 and 30.3 ± 9.5 respectively. CMR had a significantly lower LVEF compared to 2DE (p = 0.03).
There was good correlation between 3DE & CMR and 2DE & CMR, and excellent correlation between 3DE and 2DE for LVEF (Table 1). There was for trend for CMR to underestimate LVEF compared to 2DE and 3DE, with small biases although wide limits of agreement (Figure 1). There was excellent correlation of LVEDV and LVESV across all 3 techniques. CMR underestimated volumes compared to 2DE and 3DE with large biases and wide LOA.
The kappa coefficient agreement at threshold level for CRT insertion (LVEF ≤35%) was fair for 3DE and CMR (0.379, p = 0.004) and 2DE and CMR (0.462, p = 0.001), and moderate for 3DE and 2DE (0.575, p ≤ 0.001).
Conclusion – Whilst LVEF is not the only indicator to guide CRT insertion, it remains an important imaging parameter for clinical decision making. We observed large biases in left ventricular volumes between 2D, 3D and CMR. However, whilst the overall bias in LVEF is small, the wide limits of agreement (LOA) observed may represent an area of clinical uncertainty, which may impact on the dichotomous imaging threshold for CRT insertion.

Background
Myocardial inflammation may occur in the context of a multisystem disease such as sarcoidosis, adversely affecting prognosis. A definitive diagnosis of cardiac sarcoidosis (CS) is essential to implementing life-saving treatment but this is complicated by the invasive nature of endomyocardial biopsy (EMB) and its low accuracy. Positron emission tomography (PET) assists in diagnosis, which relies on visual interpretation of myocardial F-18 FDG uptake. The value of quantitative analysis and its application to clinical practice remain uncertain.
Purpose
To investigate the power of quantitative F-18 FDG PET-CT imaging analysis for detecting CS in patients with suspected disease.
Methods
All patients underwent F-18 FDG PET-CT after a 24-hour low-carbohydrate diet and 15-hour fasting as part of their diagnostic work-up for suspected cardiac inflammation. Cardiovascular magnetic resonance acted as gatekeeper to PET-CT in 8 of every 10 scans. Myocardial F-18 FDG uptake was assessed qualitatively and quantitatively using both manually drawn regions of interest and automatic polar maps to measure global and segmental standardised F-18 FDG uptake values (SUV). The coefficient of variation (CoV) was calculated to determine uptake heterogeneity. To confirm diagnosis, follow-up data regarding disease progression, further testing and treatment were collected. To allow for sufficient follow-up time, the first 40 consecutive patients from a prospective registry (n= 214; Sep 2017-Jun 2020) were included.
Results
A comprehensive clinical picture was obtained successfully in 37 patients (median [IQR], 17 [13.5] months) and a final diagnosis of CS reached in 7 (disease prevalence, 19%). EMB was performed in 2 patients only while 3 underwent PPM/ICD implantation. Significant predictors of CS were fulfilment of Japanese Ministry of Health and Welfare criteria (Wald, 6.44; p = 0.01) and left ventricular dysfunction (Wald 6.72; p = 0.01). Qualitative F-18 FDG PET-CT had a high negative (95%) but low positive (45%) predictive value for CS (sensitivity, 83%; specificity, 77%). F-18 FDG SUV CoV was the strongest imaging predictor (Wald, 6.77; p = 0.009) and was significantly higher in CS than non-CS (CoV median [quartiles], 0.26 [0.21, 0.36] and 0.12 [0.11, 0.14] respectively; p = 0.004). As per ROC curve analysis (AUC, 0.84), a CoV threshold of 0.20 was highly specific (93%) and sensitive (86%) for CS.
Conclusion
In a referring population with a low prevalence of cardiac sarcoidosis, F-18 FDG PET-CT imaging is sensitive for the detection of myocardial inflammation with active disease unlikely in patients with a negative scan. Quantitative evaluation of metabolic heterogeneity within the myocardium provides a strong, independent marker of active disease and should be considered alongside visual assessment.

Abstract
Studies on the efficacy of small molecule inhibitors in Merkel cell carcinoma (MCC) have been limited and largely inconclusive. In this study, we investigated the therapeutic potential of a potent BET degrader, BETd-246, in the treatment of MCC. We found that MCC cell lines were significantly more sensitive to BETd-246 than to BET inhibitor treatment. Therapeutic targeting of BET proteins resulted in a loss of "MCC signature" genes but not MYC expression as previously described irrespective of Merkel cell polyomavirus (MCPyV) status. In MCPyV+ MCC cells, BETd-246 alone suppressed downstream targets in the MCPyV-LT Ag axis. We also found enrichment of HOX and cell cycle genes in MCPyV- MCC cell lines that were intrinsically resistant to BETd-246. Our findings uncover a requirement for BET proteins in maintaining MCC lineage identity and point to the potential utility of BET degraders for treating MCC.

Abstract
BACKGROUND AND PURPOSE Temporal encephaloceles are increasingly visualized during neuroimaging assessment of individuals with refractory temporal lobe epilepsy, and their identification could indicate an intracranial abnormality that may be related to a potential seizure focus. Careful review by an experienced neuroradiologist may yield improved detection of TEs, and other clinical, neurophysiologic, and radiologic findings may predict their presence. MATERIALS AND METHODS Data were reviewed retrospectively in patients at our institution who were presented at a multidisciplinary conference for refractory epilepsy between January 1, 2010, and December 31, 2016. Clinical, neurophysiologic, and imaging data were collected. An expert neuroradiologist reviewed the latest MR imaging of the brain in patients for whom one was available, noting the presence or absence of temporal encephaloceles as well as other associated imaging characteristics. RESULTS A total of 434 patients were reviewed, 16 of whom were excluded due to unavailable or poor-quality MR imaging. Seven patients had temporal encephaloceles reported on initial imaging, while 52 patients had temporal encephaloceles identified on expert review. MR imaging findings were more often initially normal in patients with temporal encephaloceles (P < .001), and detection of temporal encephaloceles was increased in patients in whom 3T MR imaging was performed (P < .001), the T2 sampling perfection with application-optimized contrasts by using different flip angle evolutions sequence was used (P < .001), or the presence of radiologic findings suggestive of idiopathic intracranial hypertension was noted. Seizure onset by scalp electroencephalogram among patients with temporal encephaloceles was significantly more likely to be temporal compared with patients without temporal encephaloceles (P < .001). A significant correlation between intracranial electroencephalogram seizure onset and patients with temporal encephaloceles compared with patients without temporal encephaloceles was not observed, though there was a trend toward temporal-onset seizures in patients with temporal encephaloceles (P = .06). CONCLUSIONS Careful review of MR imaging in patients with refractory temporal lobe epilepsy by a board-certified neuroradiologist with special attention paid to a high-resolution T2 sequence can increase the detection of subtle temporal encephaloceles, and certain clinical and neurophysiologic findings should raise the suspicion for their presence.

Abstract
BACKGROUND AND PURPOSE Previous studies have evaluated various gadolinium based contrast agents and their association with gadolinium retention, however, there is a discrepancy in the literature concerning the linear agent gadobenate dimeglumine. Our aim was to determine whether an association exists between the administration of gadobenate dimeglumine and the development of intrinsic T1-weighted signal in the dentate nucleus and globus pallidus. MATERIALS AND METHODS In this single-center, retrospective study, the signal intensity of the globus pallidus, dentate nucleus, thalamus, and middle cerebellar peduncle was measured on unenhanced T1-weighted images in 29 adult patients who had undergone multiple contrast MRIs using exclusively gadobenate dimeglumine (mean, 10.1 ± 3.23 doses; range, 6-18 doses). Two neuroradiologists, blinded to the number of prior gadolinium-based contrast agent administrations, separately placed ROIs within the globi pallidi, thalami, dentate nuclei, and middle cerebellar peduncles on the last MR imaging examinations. The correlations between the globus pallidus:thalamus and the dentate nucleus:middle cerebellar peduncle signal intensity ratios with the number of gadolinium-based contrast agent administrations and cumulative dose were tested with either 1-tailed Pearson or Spearman correlations. A priori, P < .05 was considered statistically significant. RESULTS Both the globus pallidus:thalamus and dentate nucleus:middle cerebellar peduncle ratios showed significant correlation with the number of gadolinium-based contrast agent administrations (r = 0.39, P = .017, and r = 0.58, P = .001, respectively). Additionally, the globus pallidus:thalamus and dentate nucleus:middle cerebellar peduncle ratios showed significant correlation with the cumulative dose of gadobenate dimeglumine (r = 0.48, P = .004, and r = 0.43, P = .009, respectively). Dentate nucleus hyperintensity was qualitatively present on the last MR imaging in 79.3%-86.2% of patients and in all patients who had received >10 doses. CONCLUSIONS At high cumulative doses (commonly experienced by patients, for example, with neoplastic disease), gadobenate dimeglumine is associated with an increase in the globus pallidus:thalamus and dentate nucleus:middle cerebellar peduncles signal intensity ratios.

Abstract
BACKGROUND AND PURPOSE While there have been recent reports of brain retention of gadolinium following gadolinium-based contrast agent administration in adults, a retrospective series of pediatric patients has not previously been reported, to our knowledge. We investigated the relationship between the number of prior gadolinium-based contrast agent doses and increasing T1 signal in the dentate nucleus on unenhanced T1-weighted MR imaging. We hypothesized that despite differences in pediatric physiology and the smaller gadolinium-based contrast agent doses that pediatric patients are typically administered based on weighted-adjusted dosing, the pediatric brain would also demonstrate dose-dependent increasing T1 signal in the dentate nucleus. MATERIALS AND METHODS We included children with multiple gadolinium-based contrast agent administrations at our institution. A blinded reader placed ROIs within the dentate nucleus and adjacent cerebellar white matter. To eliminate reader bias, we also performed automated ROI delineation of the dentate nucleus, cerebellar white matter, and pons. Dentate-to-cerebellar white matter and dentate-to pons ratios were compared with the number of gadolinium-based contrast agent administrations. RESULTS During 20 years at our institution, 280 patients received at least 5 gadolinium-based contrast agent doses, with 1 patient receiving 38 doses. Sixteen patients met the inclusion/exclusion criteria for ROI analysis. Blinded reader dentate-to-cerebellar white matter ratios were significantly associated with gadolinium-based contrast agent doses (rs = 0.77, P = .001). The dentate-to-pons ratio and dentate-to-cerebellar white matter ratios based on automated ROI placement were also significantly correlated with gadolinium-based contrast agent doses (t = 4.98, P < .0001 and t = 2.73, P < .02, respectively). CONCLUSIONS In pediatric patients, the number of prior gadolinium-based contrast agent doses is significantly correlated with progressive T1-weighted dentate hyperintensity. Definitive confirmation of gadolinium deposition requires tissue analysis. Any potential clinical sequelae of gadolinium retention in the developing brain are unknown. Given this uncertainty, we suggest taking a cautious stance, including the use, in pediatric patients, of higher stability, macrocyclic agents, which in both human and animal studies have been shown to be associated with lower levels of gadolinium deposition, and detailed documentation of dosing. Most important, a patient should not be deprived of a well-indicated contrasted MR examination.

Abstract
Abstract
Introduction: We have previously shown reliability in isolating pure populations of cells from complex tissues using the DEPArray™. Fine Needle Aspiration (FNA) is a quick and simple procedure often performed to make a diagnosis or rule out conditions such as cancer. Although FNA is also used to assess response to treatment, the procedure is often deemed insufficient in yield and purity of tumor cells. Here we provide preliminary results showing 100% efficiency in recovering pure tumor cell populations from FNA samples of patients affected by Metastatic Breast Cancer and known to have low tumor burden (<20%) prior to using the DEPArray™ platform.
Method: FNA paraffin embedded sections (50 microns thickness) from metastases originating from breast (n=3) primary tumors were evaluated. Each FFPE curl was processed to yield single cells followed by DEPArray™ sorting based on cytokeratin (Ker), vimentin (Vim) and nuclear staining. The recovered cell populations were directly lysed in the collection tube prior to PCR-based target enrichment for next generation sequencing using Ion AmpliSeq™ CHPv2.
Results: DEPArray™ analysis allowed identification of 3 well separated cell populations, including tumor (Ker+/Vim-), stromal (Vim+/Ker) and putative EMT (Ker+/Vim+) cells. Overall, only 21% (4.3% to 42.7% range) of the total (mean of 6335) cells analyzed were of tumor (KER+/Vim-) origin. Groups of pure cells (mean 105 cells, range 15-200) for each population were recovered for sequence analysis. In one breast cancer FNA sample, we observed TP53 LoH but only in the recovered tumor (KER+) cells and not in the unsorted, stromal (VIM+), or EMT (KER+/VIM+) populations. In addition, a PIK3CA missense somatic heterozygous variant was identified in both the tumor and putative EMT populations but not in stromal cells, confirming this as a somatic mutation.
Conclusion: DEPArray™ allows resolution of two main limitations associated with FNA samples obtained for genomic analysis: too few target cells and unwanted admixture of normal cells. DEPArray™ allows for phenotypic distinction between the sorted cells prior to recovery; thus, enabling sequence analysis that is suitable for detecting genomic aberrations such as CNVs and LoH, which cannot be evaluated as precisely in an unsorted sample. Clearly, the DEPArray™ platform brings precision to detection, quantification and recovery of pure target cells that are suitable for subsequent downstream molecular analysis that can improve cancer diagnosis and personalized treatment strategies for breast cancer patients.

Abstract
Abstract
Introduction: Somatic mutations, including those in TP53, PIK3CA, and estrogen receptor alpha (ESR1), are key to the biology of cancer and response to therapy. Recently, somatic cancer-associated mutations have been identified in circulating cell free plasma tumor DNA (ptDNA). Less is known about the mutation profile of DNA extracted from CTC (CTC-DNA). Since CTC-DNA provides mutational information of single cells, we hypothesize CTC-DNA will complement ptDNA to give greater insight into tumor heterogeneity.
Methods: Patients with ER positive MBC who were enrolled in the Mi CTC-ONCOSEQ, a companion trial to Mi-ONCOSEQ (the Michigan Oncology Sequencing Program), and who had ≥5CTC/7.5 ml whole blood were included. CTC were enriched from white blood cells (WBC) with CellSearch© (CXC kit). CTC and WBC were then purified using DEPArrayTM. DNA from individual CTC and WBC was isolated and subjected to whole genomic amplification (Ampli 1TM WGA). Genetic analysis was performed on individual CTC, pooled CTC and pooled WBC DNA by multiplexed PCR based targeted next generation sequencing (NGS) using the Oncomine Comprehensive Panel (targeting ∼130 onco- and tumor suppressor genes) and the Ion Torrent Proton. All patients had exome sequencing performed on research biopsies of metastases using an Illumina HiSeq 2500 platform.
Results: This pilot study was conducted using high quality DNA from two patients assessed to date. Both patients had lobular carcinoma and as expected harbored somatic, deleterious CDH1 (E-cadherin) mutations (frameshift and non-sense) in both research biopsy and CTC-DNA. These data supported our approach. Patient #1 was TP53 wild type in her research biopsy, but multiple CTC harbored somatic TP53 frame-shift mutations (Table). Patient #2 harbored an ESR1 Y537S mutation in her research biopsy. However, only 4 of 7 CTC also harbored this somatic, heterozygous mutation.

Conclusions: We demonstrate the ability to purify CTC, isolate, and amplify DNA of suitable quality for genetic analysis using a comprehensive targeted sequencing panel. Both known and novel alterations were identified in comparison to research biopsy specimens. This approach allows single cell analysis demonstrating heterogeneity of mutational status in different single cells. Studies of CTC-ESR1 and other genetic abnormalities in patients with known tissue mutations who participated in Mi CTC-ONCOSEQ are now underway.

Abstract
Objective: an appropriate psychological intervention to promote the level of the public health and mental well-being of nurses has a great importance. This investigation was aimed to study the effectiveness of stress management training on the psychological welfare of nurses in Imam Khomeini Hospital. Methodology: this study was quasi-experimental with pretest-posttest that used a control group. Hence, 40 of the nurses in Imam Khomeini Hospital were selected by using a convenience sampling method and placed in the experimental group and the control group. Both groups were pretested by using psychological well-being 84-question scale. Afterwards, the experimental group was trained for ten sessions under stress management skill exercise, and the check group got no intervention. Next, both societies were post-tested, and the acquired data were analyzed by using inferential and descriptive statistical methods accompanied by SPSS 21 software. Findings: the results indicated that stress management training significantly led to the promotion of psychological well-being in nurses (p < 0.001). Conclusion: it was found from the research that due to the high level of effectiveness of stress management training, its low cost, and its high acceptability by the patients, especially when it was performed in a group, had a significant positive impact on the promotion of psychological well-being in nurses.

Abstract
BACKGROUND Renal transplant ureteral stricture or obstruction is a rare but devastating complication after renal transplantation. OBJECTIVE To determine the efficacy and complications of subcutaneous prosthetic ureters as a salvage procedure in transplanted kidneys with recurrent ureteral obstruction. METHODS 5 subcutaneous prosthetic ureters were inserted in 5 kidney recipients who had recurrent ureteral stenosis and failed endoscopic and open reconstructive surgeries. The prosthetic ureter consisted of an internal silicone tube covered by a coiled PTFE tube. The proximal end of the tube was introduced in the transplanted kidney percutaneously, the tube was passed through a subcutaneous tunnel, and the distal end was inserted in the bladder through a small suprapubic incision. RESULTS The mean follow-up of patients was 11.3 months. One of the patients re-operated two days after the procedure because of urinary leakage from the distal end of the prosthetic ureter. No infection or tube encrustation was encountered. CONCLUSION Subcutaneous prosthetic ureter is a safe alternative for permanent percutaneous nephrostomy in transplanted kidneys with obstructed ureter and failed endoscopic and open procedures.

Abstract
BACKGROUND Tuberculosis (TB) is an important cause of morbidity and mortality in renal transplant recipients and, because of its infrequency and the lack of medical awareness, it is usually misdiagnosed. This study was carried out to determine frequency and weight of multiple risk factors for post kidney transplantation TB. METHODS A total of 44 cases (0.3%), out of 12,820 patients from 12 major kidney transplantation centers in Iran from 1984 to 2003, were compared with 184 healthy transplant subjects who were transplanted by the same surgical team. RESULTS The mean age of cases and controls was 37.7 (13-63) and 35.6 (8-67) years (P=0.3), respectively. The mean duration of pre-transplantation hemodialysis was 30.3 (3-168) months in cases and 18.2 (1-180) months in controls (P=0.03). A positive past history of TB was detected in 2 cases and 1 control (P=0.3). The mean doses of initial and maintenance immunosuppressive drugs in cases and controls were not significantly different. A total of 25 cases (56.8%) and 60 controls (32.6%) had rejection before diagnosis of TB (P=0.004; OR=2.7, CI(95%): 1.3-5.6). CONCLUSIONS To our knowledge, this is the first study that demonstrated an increase in the risk of post-transplant TB by increasing the duration of pre-transplant hemodialysis and the number of post-transplant rejection episodes as 2 immunocompromised states. Further study is needed to clarify our new findings, specifically in relation to different immunosuppressive regimens.

Abstract
BACKGROUND In the past, the majority of renal transplantations in Iran were from living donors, but recently cadaveric donation of organs is increasing. We reviewed our experience on kidney transplantation from cadaveric donors for the past 5 years in our center. METHODS Between July 1998 and September 2004, 122 kidneys were removed from 61 cases of brain-dead patients and transplanted in 114 patients with end-stage renal disease in our center. Two kidneys had tumoral involvement and were discarded. Three kidneys were transplanted in other centers and three patients received en bloc kidney transplantations. In addition, we performed nine cases of heart, one case of liver, and one case of lung transplantations. All the recipients were followed for at least 1 year and posttreatment renal function and graft survival were determined. RESULTS All cadaveric donors were brain dead due to car (30%) and motocycle (70%) accidents, with ages ranging from 5 to 56 years (mean, 24/4 years). The mean warm and total cold ischemia times were 7 minutes and 8.1 hours, respectively. The mean distance between harvesting center and our hospital was 65 km. The 1-year graft survival was 92.3%, with mean serum creatinine of 1.76 +/- 0.79 at 1 year. Of other transplanted organs, the liver and lung recipients died 24 hours and 45 days after operation. Among heart recipients, four are still alive. CONCLUSION Cadaveric donors in developing countries including Iran can be excellent sources of organ donation.

Abstract
Successful outcomes in allopregnant women depend upon control of graft rejection mechanisms. An understanding of how the fetus escapes the maternal immune system may be relevant for the prevention of transplant rejection. It has been suggested that the same immunosuppressive cytokines contribute to successful pregnancy and transplantation. Recent reports suggest a role for transforming growth factor beta (TGF-beta) in the generation of T-regulatory lymphocytes. In contrast, production of proinflammatory cytokines accompanying intrauterine infection has been associated with fetal rejection or preterm labor. Interleukin-12 (IL-12) is the unique stimulator for differentiation of T-helper lymphocytes (Th) to Th1 cells. It rapidly induces transcription of Th1 cytokines such as interferon-gamma. This study was performed in 70 pregnant women at 21 to 36 weeks gestation, and in 32 healthy nonpregnant controls. An indirect enzyme-linked immunosorbent assay was used to estimate TGF-beta1, and IL-12 in serum. The results showed that TGF-beta1 levels were higher in all pregnant women compared with the nonpregnant controls. No significant changes in serum levels of IL-12 were observed in pregnant compared with the normal control women. The results suggested that the cytokine milieu of the placenta appeared to play a critical role in the maternal acceptance of the fetus, and that TGF-beta1 may function as a regulatory factor in fetal allograft survival during pregnancy.

Abstract
BACKGROUND Tuberculosis (TB) is an important infection encountered posttransplantation, especially among patients in developing countries, where there are high incidences of morbidity and mortality. MATERIALS AND METHODS One hundred and twenty subjects (1%) from 15 major kidney transplantation centers in Iran from 1984 to 2003 were compared with 440 controls who were matched for operative time, treatment center, and surgical team. RESULTS Mean ages of research subjects and controls were 38.6 and 36.6 years (P = .04), respectively. The mean duration of pretransplantation hemodialysis was 29 months (range, 2 to 192 months) in research subjects and 20 months (range, 1 to 180 months) in controls (P = .003). Positive past history of tuberculosis was detected in 4 (3.3%) research subjects and in 7 (1.5%) controls (P = .2). Fifty-two research subjects (43.3%) and 241 controls (54.8%) had pretransplantation purified protein derivative of tuberculin less than 5 mm (P = .02). Mean dosages of initial and maintenance immunosuppressive drugs in research subjects and in controls were not significantly different. Sixty research subjects (50%) and 152 controls (34.5%) had rejection prior to diagnosis of TB (P = .03). CONCLUSION To our knowledge, this is the first study that demonstrates an increased risk of posttransplant TB by prolonged duration of pretransplant hemodialysis and number of posttransplant rejection episodes. Further study is needed to clarify these findings specifically with respect to various immunosuppressive regimens.

Abstract
OBJECTIVE To evaluate the efficacy of a peritoneal graft for the treatment of cervical aplasia. METHOD Four patients with cervical aplasia who had a functioning endometrium and hematometra were recruited for this clinical trial. Through an abdominoperineal approach a plastic stent was inserted between the endometrial cavity and the upper part of the vagina; then, a graft of peritoneum was applied over the stent. In the absence of a vagina, grafts of skin or amniotic membrane were also used. The plastic stent was removed after 1 month in 2 patients and after 1 week in the 2 other patients. RESULT After more than 1 year of observation the 4 patients had regular menstrual cycles with normal menstruation. Sonographic examinations also showed empty uterine cavities. CONCLUSION Traditional gynecology textbooks recommend hysterectomy in cases of cervical aplasia. This report presents a new technique with 2 variations using a peritoneal graft. Although both variations were successful in the treatment of cervical aplasia in 4 women, more trials are needed to determine which one should be developed.

Abstract
Although chronic caffeine exposure during pregnancy has been shown to affect fetal growth, adverse effects of caffeine on embryogenesis are not only well understood, but also controversial. We have used gene chip technology in an attempt to identify to what extent, if any, caffeine could possibly alter gene expressions in the cytotrophoblast-like cell line BeWo. Few down-regulated genes were found; most of the genes were up-regulated, suggesting that chronic caffeine exposure during the gestational period could exert certain influences on embryogenesis. The highest up-regulated gene expression of BeWo cells by caffeine was angiotensin II type 2 (AT(2)) receptor gene. We focused the genes of the renin-angiotensin system (RAS), angiotensin II type 1 (AT(1)) and AT(2)receptors and angiotensin I converting enzyme, for study on caffeine's responsive gene expression in BeWo cells and in the placentae of pregnant rats that were fed a diet supplemented with caffeine (2 mg/100 g body weight) during gestation, and analysed the gene expressions using RT-PCR and LightCycler system. A significantly increased AT(2)receptor gene expression and a slight decreased AT(1)receptor gene expression demonstrated the caffeine's effect to the placental RAS.

Abstract
Caffeine consumption has been implicated in the development of cardiovascular disease. Therefore, in the present study, litters of rats were combined upon birth, and 8 pups were randomly assigned to each dam. Dams with pups were divided into 2 groups: group 1 received a 20% protein diet as a control, and group 2 received the 20% protein diet supplemented with caffeine (4 mg/100 g body weight). Pups from both groups were killed on days 11 and 15. Transmission electron microscopy revealed swollen, disrupted, degenerating mitochondria and intracellular edema in the hearts of rats in the caffeine groups when compared with those of the controls. Plasma Cu concentration was significantly decreased. These results indicate that early exposure to caffeine through maternal milk adversely affects cardiac mitochondria of rat pups and may be associated with decreased plasma Cu levels. It is unclear whether these results apply to the human infant. Interspecies extrapolation from rat to human must be made with caution.

Abstract
Caffeine is a substance which many people consume in their daily life. Caffeine's effects on bone are still controversial. Using ovariectomized rats, the present study was conducted to determine to what extent caffeine intake affects the mechanical properties, bone minerals and histology. Aged rats were divided into 2 groups after ovariectomy. Group 1 was fed a 20% protein diet as a control, and group 2 was fed a 20% protein diet supplemented with caffeine (2 mg/100 g body weight). The respective diets were fed to the rats of each group for 90 days. Rats were then killed by heart puncture, blood was collected, and femurs were removed. In 1 group of femurs paraffin cross-sections were made at the midshaft of each bone. Total width, cortical width, total cross-sectional bone area of the midshaft, and the number of osteocytes in randomly selected areas were measured. Another group of bones was subjected to three-point bending testing until failure. Bones were then pulverized and Ca, P, Mg, Zn, Sr, Si, hydroxyproline and hexosamine contents and crystallite size were measured. Various mechanical properties, except modulus of elasticity, in the caffeine group were consistently 7-23% lower than the noncaffeine controls. Yield strain in the caffeine group was significantly less than in the noncaffeine controls. Zinc, Sr, and crystallite size of bone showed a significant decrease in the caffeine group, whereas Si contents significantly increased. Our current results indicate that routine intake of caffeine in the elderly should be regarded with some caution.

Abstract
BACKGROUND The general public widely consumes caffeine (1,3,7-trimethylxanthine), which is contained in various foods, beverages and over-the-counter medications. We have shown previously that caffeine intake could affect bone metabolism in vivo. METHODS Because prostaglandin E2 (PGE2) is shown to be elevated in the periodontally diseased site, the possible interaction between caffeine and PGE2 was investigated in the present study using UMR106-01 rat osteoblast-like cells in vitro. RESULTS Although neither 0.1 mM caffeine nor 0.1 microg/ml of PGE2 alone showed any inhibitory effects on cell proliferation, the combination of caffeine and PGE2 showed significant inhibition. However, in order to have inhibitory effects, both caffeine and PGE2 had to be present at least 72 or 96 hours in the medium. Addition of the endogenous PGE2 synthesis inhibitor, indomethacin, showed no effects on cell proliferation. Neither cAMP-inducing agent IBMX (0.01 mM and 0.1 mM) nor forskolin (0.001 mM) inhibited cell proliferation, but combined with PGE2 these agents strongly inhibited proliferation as was observed with the combination of caffeine and PGE2, suggesting possibly that the increase of intracellular cAMP concentration plays an important role in the inhibitory effects of cell proliferation. CONCLUSIONS The present data for the first time demonstrate the possible implication of routine caffeine intake in the acceleration of pathological conditions of periodontitis. Thus, we propose that chronic caffeine intake is one of the possible risk factors in the advancement of pathology in the periodontitis patient. Further research in this area is warranted.

Abstract
The combined effects of caffeine and alcohol on mineral contents of fetal mandibles and femurs were studied. Pregnant rats were divided into four groups: group 1, control; group 2, caffeine; group 3, alcohol; and group 4, caffeine-plus-alcohol. Alcohol (1.0 g ethanol/kg body weight) was intubated twice daily, beginning at day 9 of gestation. Caffeine (2 mg/100 g body weight) was given as a dietary supplement. Groups 1 and 2 were intubated with isocaloric sucrose solution. At birth, randomly selected pups were killed and the mandible and femur were removed and dried. Ca, P, Mg, Zn and hydroxyproline in these bones were measured. Notwithstanding the dams' intake of caffeine and alcohol administered separately, the present results suggest that the combination of caffeine and alcohol exhibited the most detrimental effects.

Abstract
1. The growth of cardiac cells derived from newborn rats whose dams were either malnourished or malnourished with caffeine during pregnancy was inhibited in culture over the period of 5 days as compared to that of the normally nourished cells. 2. Cells derived from malnourished rats with caffeine added to their diets showed a greater inhibition than those from the malnourished rats not given caffeine. 3. Both DNA and protein synthesis showed an inhibition due to caffeine in a dose-dependent manner using normally nourished cells. 4. In the presence of exogenous 2 mM caffeine, the degree of percent inhibition of DNA and protein synthesis of cells derived from rats malnourished with caffeine was less than that from the rats with malnutrition alone. 5. The present data indicated that malnutrition combined with caffeine during pregnancy exerted a greater negative effect on the nature of cell growth than malnutrition alone and these cells became less sensitive to exogenous caffeine.
