Abstract
BACKGROUND Photovoice is a form of visual ethnography intended to engage impacted communities in research followed by action to ameliorate the injustices under study. Photovoice has increased in use, especially in collaboration with Latinx communities addressing health inequities. The Latinx population comprises nearly 18% of the overall United States population and according to the census is projected to reach just under 30% by 2060. This diverse panethnic community faces significant structural barriers in accessing services. Racism and the resulting marginalization, specifically, contributes to limited access to recovery services and treatment. Making meaningful advances in substance use disorder training, intervention and policy necessitates learning alongside the Latinx community. METHODS We partnered with a Latinx serving integrated behavioral health and primary care setting in Boston Massachusetts to explore barriers and facilitators to recovery using photovoice. Spanish-speaking Latinx adults with a substance use disorder participated. The group met for three photovoice sessions over a six-week period. Together group members critically analyzed photographs using the SHOWeD method. RESULTS Findings indicate a sense of purpose and meaning, security, faith and housing are important elements of recovery. The results illustrated the importance of sources of connection in maintaining sobriety. Through this photovoice project, Latinx Spanish speaking participants highlighted barriers and facilitators to their substance use disorder recovery which spanned individual, community, and structural levels. CONCLUSIONS The experiences and voices of the Latinx community are crucial to drive discussions that advance policy (e.g., housing stability and access), enhance providers' understanding of Latinx Spanish-speakers' substance use disorder recovery, and inform culturally and linguistically appropriate services. This study demonstrated that photovoice is highly acceptable and feasible among Latinx clients receiving substance use disorder services. Visual images related to housing, faith, etc. communicate challenges, power structures, as well as hopes to policymakers at multiple levels (e.g., institution/ agency, state).

Abstract
Abstract
Study question
Are IVF treatments with extremely high peak estradiol levels during ovarian hyperstimulation associated with higher complication rates?
Summary answer
Extremely high estradiol levels were not associated with higher major complication rates, but patients were more likely to seek medical care following retrieval.
What is known already
The freeze-all policy and the increasing popularity of social oocyte freezing, have led to an increase in gonadotropin doses and number of oocytes retrieved and, as a direct effect, higher estradiol levels. Studies reporting major ART complications (OHSS, bleeding, infection, torsion, thromboembolic events) are based on heterogeneous patient populations without stratification by oocyte number or estradiol levels, except for a single study reporting an association between peak estradiol levels and the risk of ovarian torsion. Extreme estradiol levels, are associated with larger ovaries, repeated ovarian punctures, and possibly a thrombogenic effect. Therefore, higher complication rates can be expected.
Study design, size, duration
A retrospective cohort study including patients from two large medical centers treated between 2019-2021.
Participants/materials, setting, methods
A study group (239 patients) with extremely high peak estradiol levels (>20,000 pmol/L on the day of ovulation induction, or > 15,000 pmol/L on the previous day) and a control group (208 patients) with normal range estradiol levels (3000-12000pmol/L), treated at two large units were included. Patients were surveyed about complaints and medical care related to ovum pick up (OPU), and medical files were reviewed. Complication rates and the need for medical assistance were compared.
Main results and the role of chance
Several differences between the study and control group were observed as a consequence of the study design: Mean age was 33.01±5.14 vs. 34.57±4.52 (p = 0.01), Mean peak estradiol levels was 26645.34±8592.56 vs.7229.750±2329.20 (p < 0.001), mean number of oocytes were 27.55±13.46 vs. 11.63±5.77 (p < 0.001) for the study and control group respectivly. More patients in the control group underwent fertility preservation. Mean FSH levels and total gonadotropin dosage were higher in the control group. Major complications [3 (1.25%) in the study group vs. 1 (0.96%) in the control group] were similar between groups (p = 0.62). In the study group Two patients were diagnosed with ovarian torsion (0.83%), and one (0.41%) with early severe OHSS as a result of a positive BhCG related to an undiagnosed pregnancy prior to OPU. All three were admitted (1.25%). In the control group one patient was diagnosed with PID requiring inpatient IV antibiotic treatment (0.48%). One more patient was admitted with severe abdominal pain following OPU, for a total of 2 admissions (0.96%) (p = 1). 33 patients (13.8%) in the study group and 10 (4.8%) in the control group sought medical care after OPU, mostly due to abdominal pain, without further workup or hospitalization (p = 0.001).
Limitations, reasons for caution
A retrospective study with possible recall bias. Major adverse events are rare in IVF and may not be fully captured in the study population.
Wider implications of the findings
Based on our results, extremely high estradiol levels during ovarian hyperstimulation were not associated with thromboembolic events, higher major complication or hospitalization rates, thus may be considered safe. Nevertheless, patients may be informed of possible higher rates of discomfort, mostly abdominal pain. Larger studies are warranted to confirm our results.

Abstract
Study question Is there an influence of mRNA COVID-19 vaccine on ovarian response and in vitro fertilization (IVF) treatment outcomes? Summary answer COVID-19 mRNA vaccine did not affect the ovarian response nor pregnancy rates in IVF treatment What is known already Studies demonstrated that infection with COVID-19 during pregnancy increased the risk of the development of severe disease and pregnancy complications. A recent meta-analysis of international data showed a declining tendency to be vaccinated, possibly influenced by public concerns over safety of the vaccines. Specifically, concerns were raised about a possible detrimental effect on fertility and pregnancy outcomes due to similarity between syncytin-1, a human placental fusion protein, and the SARS-CoV-2 spike protein expressed after administration of the COVID-19 vaccine. To date, only one retrospective analysis on 36 infertility patients has assessed the influence of COVID-19 vaccination on IVF treatment outcomes. Study design, size, duration A retrospective cohort study . The study included a total of 400 patients, 200 vaccinated women and 200 age matched non-vaccinated women, undergoing IVF treatments during January-April 2021. Participants/materials, setting, methods All vaccinated women aged 20-42 that underwent IVF treatment cycles between January 1, 2021 and April 31 2021 were included. All participants completed two doses of the BNT162b2 (Pfizer-BioNTech) vaccine at least two weeks before starting ovarian stimulation. The study group was matched by age to non-vaccinated patients that underwent IVF treatments during the same period. Patients with a positive COVID 19 test in the past were excluded. Main results and the role of chance Two hundred patients underwent oocyte retrieval 14-68 days after receiving COVID-19 vaccination. No difference was found between vaccinated and non-vaccinated patients in mean number of oocytes retrieved per cycle (10.63 vs 10.72, p = 0.93). Among 128 vaccinated patients and 133 non-vaccinated patients that underwent fresh embryos transfers, no difference was demonstrated in clinical pregnancy rates (32.8% vs. 33.1%, p-value=0.96), 42 and 44 pregnancies respectively. The fertilization rates and mean number of cryopreserved embryos were similar between the two groups in freeze all cycles (55.43% vs. 54.29%, p-value=0.73), (3.59 vs. 3.28, p-value=0.80). Among vaccinated patients and non-vaccinated patients that underwent fresh embryos transfers, no difference was demonstrated in the fertilization rate (64.81% vs. 61.98%, p = 0.51), and transferred embryos quality. Regression models applied demonstrated no effect of the vaccine on oocyte yields and pregnancy rates. Limitations, reasons for caution Limitations include retrospective nature and different treatment protocols. Additional limitation is the lack of information about vaccination status of the partners. One would assume that if unbalanced, the proportion of vaccinated males would be higher in the study group as partners tend to choose similarly in regard to vaccine administration. Wider implications of the findings Women should consider vaccination prior to their attempts to conceive via IVF treatments. Trial registration number ASF-0094-21

Abstract
Study question What is the effect of COVID-19 infection on pregnancy rates in frozen embryo transfer (FET) cycles? Summary answer Past COVID-19 infection decreased pregnancy rates in FET cycles, especially in patients with recent infection. What is known already ACE2 and TMPRSS2 are expressed in the endometrium, potentially enabling SARS-COV-2 viral invasion of the cells. Unlike with bacterial infections, the effect of viral infections in general on implantation and pregnancy rates is unclear. Some evidence suggests that early embryonic and trophoblastic infection, may result in impaired implantation or placentation. A recently published study including both recovered and vaccinated patients did not find an effect of COVID-19 immunity on FET cycle outcomes. The study did not stratify by time from infection thus the immediate consequences of infection on pregnancy rates could not be properly evaluated. Study design, size, duration A retrospective cohort study, including 41 COVID-19 recovered women, aged 20-42 years that underwent FET cycles, and 41 controls between January 1, and June 31, 2021, at a large IVF unit. Participants/materials, setting, methods Embryos transferred were the product of fresh cycles performed prior to infection. Maximal time from infection to transfer was defined as one year. The study group was matched by age, number of embryos transferred and day of transfer, to unvaccinated patients, with no history of past infection that underwent FET cycles during the same period. Demographics and cycle characteristics were recorded. Clinical and ongoing pregnancy rates were compared, with further stratification by time from infection. Main results and the role of chance Clinical pregnancy rates were 29.3% and 48.8% for the recovered and control patients respectively (p = 0.070). Ongoing pregnancy rates were 26.6% vs. 43.4% (p = 0.093). Mean age at ovum pickup (30.72 vs. 30.69; p = 0.929) and at transfer (31.56 vs. 31.58; p = 0.966) was similar between groups, as were the demographic characteristics and previous retrievals and transfers. The predominant transfer protocol used was different between groups with higher rates of natural cycle (NC) protocol in the COVID group (61% vs. 33.3%; p = 0.013. All other cycle characteristics including endometrial width, number of embryos transferred, day of embryo transfer and embryo grade were similar. Stratification by time from COVID-19 infection to transfer into ≤60 and >60 days revealed a significant difference in pregnancy rates, with recovered women having lower pregnancy rates if infected in proximity to the transfer (20.7% vs. 55.2%; p = 0.006). In a logistic regression model, infection was a significant variable (p = 0.05, OR 0.325, 95% CI 0.106-0.998). Logistic regression applied on the subgroup of women infected in proximity to the transfer, further strengthened the univariate results, with COVID-19 infection remaining a significant parameter (p = 0.005, OR 0.072, 95% CI 0.012-0.450). Limitations, reasons for caution A retrospective study, with a limited sample size, but nevertheless our results showed significant differences. Wider implications of the findings Further studies with larger groups are warranted to support these findings. Pending further information, in cases of FET cycles with limited numbers of embryos (advanced age, embryo donation, fertility preservation, embryos following sperm extraction), postponing embryo transfer for at least 60 days following recovery might be considered, if feasible.

Abstract
Study question Does prior SARS-CoV-2 infection in women undergoing fertility treatments affect outcomes of fresh ART cycles? Summary answer SARS-CoV-2 infection does not affect fresh ART treatment outcomes. A possible long term negative effect on oocyte yield should be further explored. What is known already There is evidence that the renin–angiotensin–aldosterone system (RAS) is involved in female reproductive processes such as folliculogenesis, steroidogenesis, oocyte maturation and ovulation. The existence of the ACE2 axis and ACE2 markers were confirmed in all stages of follicular maturation in the human ovary, including the granulosa cells and follicular fluid. A single previous study found no evidence that a history of asymptomatic or mild SARS-CoV-2 infection in females caused impairment of fresh ART treatment outcomes. Study design, size, duration Retrospective cohort study, including all SARS-CoV-2 infected women that underwent fresh ART cycles within a year from infection (the first cycle post infection), between October 2020 and June 2021, matched to uninfected controls. Participants/materials, setting, methods Retrospective cohort study, including all SARS-CoV-2 infected women that underwent fresh ART cycles within a year from infection (the first cycle post infection), between October 2020 and June 2021, matched to uninfected controls. Main results and the role of chance 121 infected patients and 121 controls that underwent fresh ART cycles were included. Oocyte yield (12.50 vs. 11.29; p = 0.169) and mature oocyte rate (77.71 vs. 81.76; p = 0.144) in all fresh cycles were similar between groups, as werefertilization rates, number of frozen embryos per cycle and clinical pregnancy rates (42.9% vs. 40.4%; p = 0.737) in fresh cycles with an embryo transfer. Stratification by time from COVID-19 infection by time from infection <90 day, 90-180 days and > 180 days revealed similar results with no difference in pregnancy rates. In a logistic regression model, COVID-19 infection did not affect pregnancy rates except for the small subgroup of patients who recovered more than 180 days prior to retrieval with a negative effect on oocyte yield (p = 0.018, Slope=-4.08, 95%CI 95% CI -0.7.41 – -0.75). Limitations, reasons for caution A retrospective study with data that was not uniformly generated under a study protocol, no antibody testing for the control group. Wider implications of the findings The study findings suggest that COVID-19 infection does not affect treatment outcomes in fresh ART cycles, except for a possible long term negative effect on oocyte yield when retrieval occurs > 180 days post COVID-19 infection. Further studies are warranted in order to support these findings. Trial registration number HMC-0010-21

Abstract
Introduction Because of phenotypic overlap between monogenic urinary stone diseases (USD), gene-specific analyses can result in missed diagnoses. We used targeted next generation sequencing (tNGS), including known and candidate monogenic USD genes, to analyze suspected primary hyperoxaluria (PH) or Dent disease (DD) patients genetically unresolved (negative; N) after Sanger analysis of the known genes. Cohorts consisted of 285 PH (PHN) and 59 DD (DDN) families. Methods Variants were assessed using disease-specific and population databases plus variant assessment tools and categorized using the American College of Medical Genetics (ACMG) guidelines. Prior Sanger analysis identified 47 novel PH or DD gene pathogenic variants. Results Screening by tNGS revealed pathogenic variants in 14 known monogenic USD genes, accounting for 45 families (13.1%), 27 biallelic and 18 monoallelic, including 1 family with a copy number variant (CNV). Recurrent genes included the following: SLC34A3 (n = 13), CLDN16 (n = 8), CYP24A1 (n = 4), SLC34A1 (n = 3), SLC4A1 (n = 3), APRT (n = 2), CLDN19 (n = 2), HNF4A1 (n = 2), and KCNJ1 (n = 2), whereas ATP6V1B1, CASR, and SLC12A1 and missed CNVs in the PH genes AGXT and GRHPR accounted for 1 pedigree each. Of the 48 defined pathogenic variants, 27.1% were truncating and 39.6% were novel. Most patients were diagnosed before 18 years of age (76.1%), and 70.3% of biallelic patients were homozygous, mainly from consanguineous families. Conclusion Overall, in patients suspected of DD or PH, 23.9% and 7.3% of cases, respectively, were caused by pathogenic variants in other genes. This study shows the value of a tNGS screening approach to increase the diagnosis of monogenic USD, which can optimize therapies and facilitate enrollment in clinical trials.

Abstract
PURPOSE To emphasize the burden that chronic kidney disease (CKD) and its complications place on overall health and well-being over the lifetime in individuals with congenital and acquired urinary tract abnormalities. METHODS Topic-based literature review was performed and professional opinion was obtained to describe the scope of medical challenges faced by both teens and adults and their health care providers in the context of congenital and acquired urinary tract abnormalities. RESULTS Challenges include accurate assessment of glomerular filtration rate; engaging for consistent surveillance of blood pressure, proteinuria, and medical complications of CKD that increase the risk of progression to end-stage renal disease and affect general health; achieving early referral to nephrology for better outcomes; managing renal complications within the unique limitations of lower urinary tract function; treating upper tract urolithiasis in the atypical urinary tract; and preparing for successful renal transplant. CONCLUSION In individuals with congenital or acquired abnormalities of the urinary tract, there is an inherent risk of CKD with its associated morbidity and increased mortality risk. Interplay between the upper and lower urinary tract impacts CKD progression. Collaborative management between urology and nephrology is highly recommended to address the unique challenges for each individual over the lifetime.

Abstract
t a novel miniaturized multi sensor implant for monitoring hemodynamic parameters in cardiovascular regions. Pressure measurements are performed with a highly accurate capacitive pressure sensor. An additional acceleration and temperature sensor allows compensating the impact of patient's inclination and temperature variations on the pressure measurement, respectively. A multi-functional transponder application-specific integrated circuit (ASIC) manages sensor signal processing, storage of ID, sensor calibration data, telemetric energy, and data transmission with an extracorporeal reading unit. Each component of the implant is assembled on a low temperature co-fired ceramics (LTCC) circuit board with an integrated antenna coil enabling an inductive near-field coupling at a frequency of 13.56 MHz. For a streamlined shape and reduction of thrombogenicity, the implant is encapsulated by biocompatible polymers.

Abstract
Abstract
A bimodal pattern of hazard of relapse among early stage breast cancer patients has been identified in multiple databases from US, Europe and Asia. We have been studying these data to determine if this can lead to new ideas on how to prevent relapse in breast cancer. Using computer simulation and access to a very high quality database from Milan for patients treated with mastectomy only, we proposed that relapses within 3 years of surgery are stimulated somehow by the surgical procedure. During the week post surgery, metastatic development is enhanced 100 fold according to the simulation. Most relapses in breast cancer are in this early category. Retrospective data from a Brussels anesthesiology group suggested a plausible mechanism. Use of ketorolac, a common NSAID analgesic used in surgery was associated with far superior disease-free survival in the first 5 years after surgery. The expected prominent early relapse events in months 9-18 are reduced 5-fold. Transient systemic inflammation accompanying surgery (identified by IL-6 in serum) could facilitate angiogenesis of dormant micrometastases, proliferation of dormant single cells, and seeding of circulating cancer stem cells resulting in early relapse and could have been effectively blocked by the perioperative anti-inflammatory agent. If this observation holds up to further scrutiny, it could mean that the simple use of this safe, inexpensive and effective anti-inflammatory agent at surgery might eliminate early relapses. Similar bimodal patterns have been identified in other cancers suggesting a general effect. Based on the writings of Galen and Celsus, metastatic development after breast tumors were removed was known to them 2000 years ago.
This effect has been demonstrated recently in a mouse model by Krall et al Science Translational Medicine and reviewed in NEJM by Komaroff. In a series of experiments in 273 mice, aggressive mouse breast cancer cells were implanted in various locations. Initially, the tumor cells grew but then became dormant. This dormancy occurred only in mice with intact immunity, which suggests that the immune system can contain certain dormant metastases. Surgery of any type (including resection of a primary tumor) led to aggressive growth of metastases in 60% of animals, compared with 10% of control animals that did not undergo surgery. Surgical procedures caused systemic inflammatory responses. Activated monocytes from the marrow traveled to the sites of the dormant metastases and became tumor associated macrophages. These macrophages suppressed the immune system near the tumor, awakening the metastases from their dormancy. Treating the animals with NSAIDs before and immediately following surgery greatly attenuated growth of these metastases.
Since this effect has by now been shown in two Belgian retrospective studies as well as a mouse model we suggest this be tested in one or more clinical trials. We also note that the bleeding potential from using NSAIDs before surgery can apparently be reduced with the use of Tranexamic Acid – currently being tested in a clinical trial for mastectomy.

Abstract
Ovarian follicular development and ovulation are complex and tightly regulated processes that involve regulation by microRNAs (miRNAs). We previously identified differentially expressed mRNAs between human cumulus granulosa cells (CGCs) from immature early antral follicles (germinal vesicle - GV) and mature preovulatory follicles (metaphase II - M2). In this study, we performed an integrated analysis of the transcriptome and miRNome in CGCs obtained from the GV cumulus-oocyte complex (COC) obtained from IVM and M2 COC obtained from IVF. A total of 43 differentially expressed miRNAs were identified. Using Ingenuity IPA analysis, we identified 7288 potential miRNA-regulated target genes. Two hundred thirty-four of these target genes were also found in our previously generated ovulatory gene library while exhibiting anti-correlated expression to the identified miRNAs. IPA pathway analysis suggested that miR-21 and FOXM1 cooperatively inhibit CDC25A, TOP2A and PRC1. We identified a mechanism for the temporary inhibition of VEGF during ovulation by TGFB1, miR-16-5p and miR-34a-5p. The linkage bioinformatics analysis between the libraries of the coding genes from our preliminary study with the newly generated library of regulatory miRNAs provides us a comprehensive, integrated overview of the miRNA-mRNA co-regulatory networks that may play a key role in controlling post-transcriptomic regulation of the ovulatory process.

Abstract
A low-intervention policy for Hickman catheter maintenance has been evaluated and found to be safe and cost effective. A simple, lightweight, disposable device has been used for 24–hour ambulatory home infusion. Implementation of this policy as part of a prospective randomized trial of single-agent chemotherapy in advanced breast cancer has demonstrated that slow intravenous infusion reduces the acute toxicity of epirubicin when compared with bolus injection.

Abstract
We describe some preliminary findings from a pilot study using three recently developed questionnaires which assessed items such as the health beliefs, knowledge about cancer and attitudes to breast cancer screening in 242 women invited to attend for mammographic screening in South East London. We suggest that these questionnaires should be used in all regional centres both to monitor psychological variables and to identify local problems within the service which may be influencing the up-take of invitations to come for screening.

Abstract
BACKGROUND Steroid-resistant nephrotic syndrome (SRNS) is the second most frequent cause of end-stage renal disease (ESRD) among patients manifesting at under 25 years of age. We performed mutation analysis using a high-throughput PCR-based microfluidic technology in 24 single-gene causes of SRNS in a cohort of 72 families, who presented with SRNS before the age of 25 years. METHODS Within an 18-month interval, we obtained DNA samples, pedigree information, and clinical information from 77 consecutive children with SRNS from 72 different families seen at Boston Children's Hospital (BCH). Mutation analysis was completed by combining high-throughput multiplex PCR with next-generation sequencing. We analyzed the sequences of 18 recessive and 6 dominant genes of SRNS in all 72 families for disease-causing variants. RESULTS We identified the disease-causing mutation in 8 out of 72 (11.1%) families. Mutations were detected in the six genes: NPHS1 (2 out of 72), WT1 (2 out of 72), NPHS2, MYO1E, TRPC6, and INF2. Median age at onset was 4.1 years in patients without a mutation (range 0.5-18.8), and 3.2 years in those in whom the causative mutation was detected (range 0.1-14.3). Mutations in dominant genes presented with a median onset of 4.5 years (range 3.2-14.3). Mutations in recessive genes presented with a median onset of 0.5 years (range 0.1-3.2). CONCLUSION Our molecular genetic diagnostic study identified underlying monogenic causes of steroid-resistant nephrotic syndrome in ~11% of patients with SRNS using a cost-effective technique. We delineated some of the therapeutic, diagnostic, and prognostic implications. Our study confirms that genetic testing is indicated in pediatric patients with SRNS.

Abstract
Many issues plague the pediatric ARF outcome literature, which include data only from single center sources, a relative lack of prospective study, mixture within studies of renal replacement therapy modality without stratification and inconsistent use of methods to control for patient illness severity in outcome analysis. Since January 2001, the Prospective Pediatric CRRT (ppCRRT) Registry Group has been collecting data from multiple United States pediatric centers to obtain demographic data regarding pediatric patients who receive CRRT, assess the effect of different CRRT prescriptions on circuit function and evaluate the impact of clinical variables on patient outcome. The aim of the current paper is to describe the ppCRRT Registry design, review the decision process and rationale for the options chosen for the ppCRRT format and discuss the analysis plan and future projects envisioned for the ppCRRT Registry.

Abstract
BACKGROUND AND OBJECTIVES Steroid-resistant nephrotic syndrome overwhelmingly progresses to ESRD. More than 30 monogenic genes have been identified to cause steroid-resistant nephrotic syndrome. We previously detected causative mutations using targeted panel sequencing in 30% of patients with steroid-resistant nephrotic syndrome. Panel sequencing has a number of limitations when compared with whole exome sequencing. We employed whole exome sequencing to detect monogenic causes of steroid-resistant nephrotic syndrome in an international cohort of 300 families. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Three hundred thirty-five individuals with steroid-resistant nephrotic syndrome from 300 families were recruited from April of 1998 to June of 2016. Age of onset was restricted to <25 years of age. Exome data were evaluated for 33 known monogenic steroid-resistant nephrotic syndrome genes. RESULTS In 74 of 300 families (25%), we identified a causative mutation in one of 20 genes known to cause steroid-resistant nephrotic syndrome. In 11 families (3.7%), we detected a mutation in a gene that causes a phenocopy of steroid-resistant nephrotic syndrome. This is consistent with our previously published identification of mutations using a panel approach. We detected a causative mutation in a known steroid-resistant nephrotic syndrome gene in 38% of consanguineous families and in 13% of nonconsanguineous families, and 48% of children with congenital nephrotic syndrome. A total of 68 different mutations were detected in 20 of 33 steroid-resistant nephrotic syndrome genes. Fifteen of these mutations were novel. NPHS1, PLCE1, NPHS2, and SMARCAL1 were the most common genes in which we detected a mutation. In another 28% of families, we detected mutations in one or more candidate genes for steroid-resistant nephrotic syndrome. CONCLUSIONS Whole exome sequencing is a sensitive approach toward diagnosis of monogenic causes of steroid-resistant nephrotic syndrome. A molecular genetic diagnosis of steroid-resistant nephrotic syndrome may have important consequences for the management of treatment and kidney transplantation in steroid-resistant nephrotic syndrome.

Abstract
BACKGROUND Barley (Hordeum vulgare L.) is a major cereal crop, which is cultivated under variable environmental conditions and abiotic stresses in marginal areas around the globe. In this study, we evaluated 150 Jordanian landraces obtained from ICARDA Gene Bank and four local checks for yield and yield components related-traits in two locations across Jordan for three growing seasons under rainfed conditions. The study aims to identify superior Jordanian barley genotypes under dry conditions, to understand the genotype × environment (G × E) interactions, to analyze stability parameters and to identify markers associated with yield and yield components under rainfed conditions. RESULTS The barley accessions exhibited significant variation for all traits studied. Three accessions with high yield, cultivar superiority and stability under specific environments were identified with accession G69 is the highest yielding and superior for Madaba and overall environments and G144 is the highest yielding at Ramtha. Accession G123 was high yielding in all environments and was stable across different environments. At the genetic level, the Jordanian landraces were found to be diverse with a clustering that was based on row-type. The GWAS analysis identified 77 significant markers-traits associations for multiple traits including grain yield (GY) with three significant QTLs located at 1H, 2H and 7H, which seem important for dry environments. CONCLUSION Utilizing Jordanian barley landraces can effectively improve and adapt the current barley cultivars for cultivation under environmental stresses in dry regions. Utilization of markers associated with important agronomical traits and their incorporation in breeding using marker assisted selection can improve barley tolerance to drought stress.

Abstract
Polarized neutron scattering experiments reveal that type-II multiferroics allow for controlling the spin chirality by external electric fields even in the absence of long-range multiferroic order. In the two prototype compounds TbMnO_{3} and MnWO_{4}, chiral magnetism associated with soft overdamped electromagnons can be observed above the long-range multiferroic transition temperature T_{MF}, and it is possible to control it through an electric field. While MnWO_{4} exhibits chiral correlations only in a tiny temperature interval above T_{MF}, in TbMnO_{3} chiral magnetism can be observed over several kelvin up to the lock-in transition, which is well separated from T_{MF}.

Abstract
Nephrolithiasis, a condition in which urinary supersaturation leads to stone formation in the urinary system, affects about 5%-10% of individuals worldwide at some point in their lifetime and results in significant medical costs and morbidity. To date, mutations in more than 30 genes have been described as being associated with nephrolithiasis, and these mutations explain about 15% of kidney stone cases, suggesting that additional nephrolithiasis-associated genes remain to be discovered. To identify additional genes whose mutations are linked to nephrolithiasis, we performed targeted next-generation sequencing of 18 hypothesized candidate genes in 348 unrelated individuals with kidney stones. We detected biallelic mutations in SLC26A1 (solute carrier family 26 member 1) in two unrelated individuals with calcium oxalate kidney stones. We show by immunofluorescence, immunoblotting, and glycosylation analysis that the variant protein mimicking p.Thr185Met has defects in protein folding or trafficking. In addition, by measuring anion exchange activity of SLC26A1, we demonstrate that all the identified mutations in SLC26A1 result in decreased transporter activity. Our data identify SLC26A1 mutations as causing a recessive Mendelian form of nephrolithiasis.

Abstract
BACKGROUND AND OBJECTIVES Nephrolithiasis is a prevalent condition that affects 10%-15% of adults in their lifetime. It is associated with high morbidity due to colicky pain, the necessity for surgical intervention, and sometimes progression to CKD. In recent years, multiple monogenic causes of nephrolithiasis and nephrocalcinosis have been identified. However, the prevalence of each monogenic gene in a pediatric renal stone cohort has not yet been extensively studied. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS To determine the percentage of cases that can be explained molecularly by mutations in one of 30 known nephrolithiasis/nephrocalcinosis genes, we conducted a high-throughput exon sequencing analysis in an international cohort of 143 individuals <18 years of age, with nephrolithiasis (n=123) or isolated nephrocalcinosis (n=20). Over 7 months, all eligible individuals at three renal stone clinics in the United States and Europe were approached for study participation. RESULTS We detected likely causative mutations in 14 of 30 analyzed genes, leading to a molecular diagnosis in 16.8% (24 of 143) of affected individuals; 12 of the 27 detected mutations were not previously described as disease causing (44.4%). We observed that in our cohort all individuals with infantile manifestation of nephrolithiasis or nephrocalcinosis had causative mutations in recessive rather than dominant monogenic genes. In individuals who manifested later in life, causative mutations in dominant genes were more frequent. CONCLUSIONS We present the first exclusively pediatric cohort examined for monogenic causes of nephrolithiasis/nephrocalcinosis, and suggest that important therapeutic and preventative measures may result from mutational analysis in individuals with early manifestation of nephrolithiasis or nephrocalcinosis.

Abstract
The control of multiferroic domains through external electric fields has been studied by dielectric measurements and by polarized neutron diffraction on single-crystalline TbMnO3. Full hysteresis cycles were recorded by varying an external field of the order of several kV mm(-1) and by recording the chiral magnetic scattering as well as the charge in a sample capacitor. Both methods yield comparable coercive fields that increase upon cooling.

Abstract
The main goal of this study was to investigate the genetic basis of yield and grain quality traits in winter wheat genotypes using association mapping approach, and identify linked molecular markers for marker assisted selection. A total of 120 elite facultative/winter wheat genotypes were evaluated for yield, quality and other agronomic traits under rain-fed and irrigated conditions for two years (2011–2012) at the Tel Hadya station of ICARDA, Syria. The same genotypes were genotyped using 3,051 Diversity Array Technologies (DArT) markers, of which 1,586 were of known chromosome positions. The grain yield performance of the genotypes was highly significant both in rain-fed and irrigated sites. Average yield of the genotypes ranged from 2295 to 4038 kg/ha and 4268 to 7102 kg/ha under rain-fed and irrigated conditions, respectively. Protein content and alveograph strength (W) ranged from 13.6–16.1% and 217.6–375 Jx10-4, respectively. DArT markers wPt731910 (3B), wPt4680 (4A), wPt3509 (5A), wPt8183 (6B), and wPt0298 (2D) were significantly associated with yield under rain-fed conditions. Under irrigated condition, tPt4125 on chromosome 2B was significantly associated with yield explaining about 13% of the variation. Markers wPt2607 and wPt1482 on 5B were highly associated with protein content and alveograph strength explaining 16 and 14% of the variations, respectively. The elite genotypes have been distributed to many countries using ICARDA’s International system for potential direct release and/or use as parents after local adaptation trials by the NARSs of respective countries. The QTLs identified in this study are recommended to be used for marker assisted selection after through validation using bi-parental populations.

Abstract
Nephrolithiasis is a prevalent condition with a high morbidity. Although dozens of monogenic causes have been identified, the fraction of single-gene disease has not been well studied. To determine the percentage of cases that can be molecularly explained by mutations in 1 of 30 known kidney stone genes, we conducted a high-throughput mutation analysis in a cohort of consecutively recruited patients from typical kidney stone clinics. The cohort comprised 272 genetically unresolved individuals (106 children and 166 adults) from 268 families with nephrolithiasis (n=256) or isolated nephrocalcinosis (n=16). We detected 50 likely causative mutations in 14 of 30 analyzed genes, leading to a molecular diagnosis in 14.9% (40 of 268) of all cases; 20 of 50 detected mutations were novel (40%). The cystinuria gene SLC7A9 (n=19) was most frequently mutated. The percentage of monogenic cases was notably high in both the adult (11.4%) and pediatric cohorts (20.8%). Recessive causes were more frequent among children, whereas dominant disease occurred more abundantly in adults. Our study provides an in-depth analysis of monogenic causes of kidney stone disease. We suggest that knowledge of the molecular cause of nephrolithiasis and nephrocalcinosis may have practical implications and might facilitate personalized treatment.

Abstract
The spherical aberration generated when focusing from air into another medium limits the depth at which ultrafast laser machining can be accurately maintained. We investigate how the depth range may be extended using aberration correction via a liquid crystal spatial light modulator (SLM), in both single point and parallel multi-point fabrication in fused silica. At a moderate numerical aperture (NA = 0.5), high fidelity fabrication with a significant level of parallelisation is demonstrated at the working distance of the objective lens, corresponding to a depth in the glass of 2.4 mm. With a higher numerical aperture (NA = 0.75) objective lens, single point fabrication is demonstrated to a depth of 1 mm utilising the full NA, and deeper with reduced NA, while maintaining high repeatability. We present a complementary theoretical model that enables prediction of the effectiveness of SLM based correction for different aberration magnitudes.

Abstract
Management of the axilla in breast cancer patients has been a subject of intense debate and controversy. Axillary lymph node status is still considered to be the single most important prognostic indicator in breast cancer patients. Despite a tendency toward a conservative approach for the surgery of primary breast carcinoma, axillary lymph node dissection (ALND) has remained an integral part of breast cancer management for more than a century. Among patients with T1/T2 tumors, up to 70% have a negative axillary dissection, and more than 50% of these node-negative patients develop morbidity related to ALND. It is ironic that the extent, morbidity, and cost of a staging procedure (ALND) is more than that of the surgical treatment of the primary tumor. We must readdress the question of axillary management in breast carcinoma in the light of information gained from the sentinel node biopsy trials around the world. We review the historical milestones and various modalities used for axillary management, discuss the concept of sentinel node biopsy for breast carcinoma, and propose a management plan.

Abstract
Spring growth in barley controlled by natural variation at Vrn-H1 and Vrn-H2 improved yield stability in marginal Syrian environments. The objective of the present study was to identify QTL influencing agronomic performance in rain-fed Mediterranean environments in a recombinant inbred line (RIL) population, ARKE derived from the Syrian barley landrace, Arta and the Australian feed cultivar, Keel. The population was field tested for agronomic performance at two locations in Syria for 4 years with two sowing dates, in autumn and winter. Genotypic variability in yield of the RIL population was mainly affected by year-to-year variation presumably caused by inter-annual differences in rainfall distribution. The spring growth habit and early flowering inherited from the Australian cultivar Keel increased plant height and biomass and improved yield stability in Syrian environments. QTL for yield and biomass coincided with the map location of flowering time genes, in particular the vernalisation genes Vrn-H1 and Vrn-H2. In marginal environments with terminal drought, the Vrn-H1 allele inherited from Keel improved final biomass and yield. Under changing climate conditions, such as shorter winters, reduced rainfall, and early summer drought, spring barley might thus outperform the traditional vernalisation-sensitive Syrian landraces. We present the ARKE population as a valuable genetic resource to further elucidate the genetics of drought adaptation of barley in the field.

Abstract
Nanoparticles of transparent conducting oxides, such as indium tin oxide, can be used in printing techniques to generate functional layers for various optoelectronic devices. Since these deposition methods do not create fully consolidated films, the optical properties of such layers are expected to be notably different from those of the bulk material and should be characterized on their own. In this work we present a way to measure the effective refractive index of a particulate ITO layer by refraction of light. The obtained data points are used to identify an accurate layer model for spectroscopic ellipsometry. In this way the complex refractive index of the particle layer is determined in a wide spectral range from ultra violet to near infrared.
