Thyroid US-guided FNA techniques: A prospective,randomized controlled study.

BACKGROUND: Thyroid nodules are common in the general population. Ultrasonography is the most efficient diagnostic approach to evaluate thyroid nodules. The US FNAC procedure can be performed using either the short axis (perpendicular), or a long axis (parallel) approach to visualize the needle as it is advanced toward the desired nodule. The main aim of this study was to compare the percentage of non-diagnostic results between the long and short axis approach. METHODS: A prospective study that included a randomized controlled trial and was divided into two arms-the short axis and the long axis-was conducted. A total of 245 thyroid nodules were collected through the fine needle aspiration cytology, performed with ultrasound, from march 2021 to march 2022. The patient's demographic information were collected and also nodules characteristics. RESULTS: Of 245 nodules sampled, 122 were sampled with the long axis method, while 123 with the short axis method. There is not significantly less non diagnostic approach with either method compared to the other (11.5 % vs 16.3 % respectively). DISCUSSION: Previous studies came to the conclusion that the long axis method yields fewer non diagnostic samples. This study evaluated the two FNA approaches which were proceeded by the same physician who is expert in both techniques. CONCLUSION: The US FNAC performed in the long axis approach will not produce more conclusive results and less non diagnostic results (Bethesda category 1) than the short axis approach one.

High sensitivity and specificity in fetal gender identification in the first trimester, using ultrasound and Noninvasive Prenatal Screening (NIPS) in twin pregnancies, a prospective study.

INTRODUCTION: Determination of the fetal gender in the first trimester is important in twin pregnancy cases of familial X-linked genetic syndromes and helps determine chorionicity. We assessed and compared the accuracy of first-trimester ultrasound scans, and cell-free fetal DNA (CfDNA) in determining fetal gender in the first trimester of twin pregnancies. METHODS: Women with twin pregnancies were recruited prospectively during the first trimester. Fetal gender was determined using both ultrasound scans and CfDNA screening. Both results were compared to the newborn gender after delivery. RESULTS: A total of 113 women with twin pregnancies were enrolled. There was 100% sensitivity and specificity in Y chromosome detection using CfDNA. Gender assignment using ultrasound in any first-trimester scans was 79.7%. Accuracy level increased from 54.2% in CRL 45-54 mm to 87.7% in CRL 55-67 mm and 91.5% in CRL 67-87 mm. Male fetuses had significantly higher chances of a gender assignment error compared to female fetuses, odds ratio = 23.574 (CI 7.346 - 75.656). CONCLUSIONS: CfDNA is highly sensitive and specific in determining the presence of the Y chromosome in twin pregnancies in the first trimester. Between CRL 55-87 mm, ultrasound scanning offers a highly accurate determination of fetal gender in twin pregnancies.

Fetal surgery using fetoscopic endoluminal tracheal occlusion for severe congenital diaphragmatic hernia: a single-center experience.

PURPOSE: To provide a comprehensive report of the experience gained in the prenatal treatment of congenital diaphragmatic hernia (CDH) using fetoscopic endoluminal tracheal occlusion (FETO) following its implementation at a newly established specialized fetal medicine center. METHODS: Mothers of fetuses with severe CDH were offered prenatal treatment by FETO. RESULTS: Between 2018 and 2021, 16 cases of severe CDH underwent FETO. The median gestational age (GA) at balloon insertion was 28.4 weeks (IQR 27.8-28.6). The median GA at delivery was 37 weeks (IQR 34.4-37.8). The survival rate was 8/16 cases (50%). None of the survivors required home oxygen therapy at 6 months of age. Comparison between the survivors and deceased showed that survivors had balloon insertion 1 week earlier (27.8 vs. 28.4 weeks, p = 0.007), a higher amniotic fluid level change between pre- to post-FETO (3.4 vs 1.3, p = 0.024), a higher O/E LHR change between pre- to post-FETO (50.8 vs. 37.5, p = 0.047), and a GA at delivery that was 2 weeks later (37.6 vs. 35.4 weeks, p = 0.032). CONCLUSIONS: The survival rate at 6 months of age in cases of severe CDH treated with FETO in our center was 50%. Our new fetal medicine center matches the performance of other leading international centers.

Burnout in Israeli medical students: a national survey.

INTRODUCTION: Professional burnout is characterized by loss of enthusiasm for work, cynicism, and a low sense of personal efficacy. Burnout may adversely affect medical professionalism. Burnout is common in clinicians and varying rates have been reported in medical students. No data exist regarding the prevalence of burnout among Israeli medical students. The aims of this study were to assess the rate of burnout in Israeli medical students and to identify students who were particularly susceptible to burnout. METHODS: A cross-sectional questionnaire design was employed, gathering data from medical students in all years of study across three medical schools. Burnout was measured using the Maslach Burnout Inventory Student Survey (MBI-SS), translated into Hebrew. RESULTS: Of the 2160 students in the participating medical schools, 966 (44.7%) completed MBI-SS and demographic questionnaires. The overall burnout rate was 50.6%. Multivariate logistic regression analysis yielded that female gender, age under 25, advanced year of study, studying at a specific medical school and not being a parent are all significantly correlated with higher levels of burnout. CONCLUSIONS: A high rate of burnout was found. The identification of young women who are not parents during advanced years of studies as being at-risk is important, in order to guide the development of burnout prevention interventions.

Implantable Loop Recorders in Patients with Unexplained Syncope: Does Ethnic Background Influence Diagnostic Yield?

BACKGROUND: Implantable loop recorders (ILRs) are a central tool in the evaluation of unexplained syncope. These devices record and store electrocardiograms, both automatically and on patient-dependent activation. Therefore, obtaining optimal diagnostic results relies on a patient's comprehension and collaboration. OBJECTIVES: To evaluate the effect of ethnic background and mother-tongue language on the diagnostic yield (DY) of ILRs. METHODS: Patients at two medical centers in Israel, who had ILRs as part of syncope workup were included. Inclusion criteria were age over 18 years and an ILR for at least one year (or less if the cause of syncope was detected). Patient demographics, ethnic background, and previous medical history were recorded. All findings from ILR recordings, activation mode (manual vs. automatic), and treatment decisions (none, ablation, device implantation) were collected. RESULTS: The study comprised 94 patients, 62 Jews (i.e., ethnic majority) and 32 non-Jews (i.e., ethnic minority). While baseline demographic characteristics, medical history, and drug therapy were similar in both groups, Jewish patients were significantly older at the time of device implantation: 64.3 ± 16.0 years of age vs. 50.6 ± 16.9, respectively; (P < 0.001). Arrhythmias recorded in both groups as well as treatment decisions and device activation mode were similar. Total follow-up time from device implantation was longer in the non-Jewish vs. the Jewish group (17.5 ± 12.2 vs. 24.0 ± 12.4 months, respectively; P < 0.017). CONCLUSIONS: The DY of ILR implanted for unexplained syncope did not seem to be influenced by patient's mother-tongue language or ethnicity.

Augmented Placental Protein 13 in Placental-Associated Extracellular Vesicles in Term and Preterm Preeclampsia Is Further Elevated by Corticosteroids.

Placental protein 13 (PP13) is a regulatory protein involved in remodeling the vascular system of the pregnancy and extending the immune tolerance of the mother to the growing fetus. PP13 is localized on the surface of the syncytiotrophoblast. An ex vivo placental model shows that the PP13 is released via placental-associated extracellular vesicles (PEVs) to the maternal uterine vein. This exploratory study aimed to determine PEV-associated PP13 in the maternal circulation as compared to the known soluble fraction since each has a specific communication pathway. Patients admitted to Bnai Zion Medical Center for delivery were recruited, and included 19 preeclampsia (PE) patients (7 preterm PE gestational age < 37 weeks' gestation), 16 preterm delivery (PTD, delivery at GA < 37 weeks' gestation), and 15 matched term delivery controls. Treatment by corticosteroids (Celestone), which is often given to patients with suspected preterm PE and PTD, was recorded. The PEV proteome was purified from the patients' plasma by size exclusion chromatography (SEC) to separate the soluble and PEV-associated PP13. The total level of PP13 (soluble and PEV-associated) was determined using mild detergent that depleted the PEV proteome. PP13 fractions were determined by ELISA with PP13 specific antibodies. ELISA with alkaline phosphatase (PLAP)- and cluster differentiation 63 (CD63)-specific antibodies served to verify the placental origin of the PEVs. SPSS was used for statistical analysis. The patients' medical, pregnancy, and delivery records in all groups were similar except, as expected, that a larger number of PE and PTD patients had smaller babies who were delivered earlier, and the PE patients had hypertension and proteinuria. The SEC analysis detected the presence of PP13 in the cargo of the PEVs and on their surface, in addition to the known soluble fraction. The median soluble PP13 was not significantly different across the PE, PTD, and term delivery control groups. However, after depleting the PEV of their proteome, the total PP13 (soluble and PEV-associated) was augmented in the cases of preterm PE, reaching 2153 pg/mL [IQR 1866-2838] but not in cases of PTD reaching 1576 pg/mL [1011-2014] or term delivery groups reaching 964 pg/mL [875-1636]), p < 0.01. On the surface of the circulating PEV from PTD patients, there was a decrease in PP13. Corticosteroid treatment was accompanied by a massive depletion of PP13 from the PEV, especially in preterm PE patients. This exploratory study is, thus, the first to determine PEV-associated PP13 in maternal circulation, providing a quantitative determination of the soluble and the PEV-associated fractions, and it shows that the latter is the larger. We found an increase in the amount of PP13 carried via the PEV-associated pathway in PE and PTD patients compared to term delivery cases, which was further augmented when the patients were treated with corticosteroids, especially in preterm PE. The signal conveyed by this novel communication pathway warrants further research to investigate these two differential pathways for the liberation of PP13.

Cycle threshold responses in SARS-COV2 PCR tests depend on the method by which the samples were obtained and require strict global standardization.

PURPOSE: Since 2020, a SARS-COV2 epidemic has been raging worldwide. The cycle of the PCR test in which the virus is detected is called cycle threshold (CT). The method of obtaining the sample is not detailed in any published study and is based on general guidelines of the CDC. Our contention is that the manner in which the sample is obtained has a dramatic effect on CT values. METHODS: For each person suspected of having Covid-19 who arrives at the emergency room, two swabs are taken in succession, one according to CDC guidelines and the other according to "Ziv" guidelines. The Ziv method sample collection guidelines determine the depth of penetration, the number of rotations of the swab, and their direction. Each double sample was sent for analysis. RESULTS: Analysis of the CT results of the sample to results methods and of the Seegene platform clearly found (p = 0.003 and p = 0.001, respectively) that more rigorous sample collection yielded lower CT values. CONCLUSION: The method of obtaining the samples had a dramatic effect on CT results. Any publication that includes CT results, and certainly studies that discuss CT kinetics, must describe in detail the method by which the samples were obtained. In places where it is also important to detect the onset of illness (airports, hospitals, schools, etc.), it is important to use the Ziv method to reduce the risk of false negatives.

Impact of Prior Statin Therapy on 1-year Recurrence and Length of Hospitalization for Acute Idiopathic Pericarditis.

BACKGROUND: Statins have anti-inflammatory effects that are independent of their lipid-lowering activity. OBJECTIVES: To examine whether prior statins therapy affects the clinical course of the first episode of acute idiopathic pericarditis (AIP) as the 1-year recurrence and length of hospitalization (LOH). METHODS: This retrospective study included 148 subjects with first episode AIP admitted between the years 2015 and 2019. Data were collected from two hospitals in Northern Israel. We divided the patients in into two groups: 117 those without statins use and 31 those with prior statins use. We compared age, sex, co-morbidities, drugs, laboratory data, 1-year recurrence, and LOH. RESULTS: The mean age of participants was 43.1 ± 19.4 years. Comparisons between subjects without statins and with prior statins use were made according to age (37.5 ± 16.7 years vs. 64.4 ± 12.7 years, P < 0.01), C-reactive protein (50 ± 40 vs. 48 ± 35 mg/dl, P = 0.9), LOH (5.4 ± 2.85 vs. 8.03 ± 4.92 days, P < 0.01), 1-year recurrence of pericarditis (23 vs. 6 cases, P = 0.95), respectively. Multivariate logistic regression analysis revealed that 1-year recurrence (odds ratio [OR] 0.8, 95% confidence interval [95%CI 0 0.6-1.1, P = 0.41), was not associated with prior statin use, while LOH (OR 2.56, 95%CI 2.08-2.75, P = 0.01) was prolonged with prior statins use in patients with first episode of AID. CONCLUSIONS: Prior statins use in patients with the first episode of AIP did not reduce the 1-year recurrence of pericarditis and prolong the LOH.

When to start tacrolimus ointment for vernal keratoconjunctivitis? A proposed treatment protocol.

PURPOSE: The aim of this study was to compare treatment regimens of tacrolimus and of topical steroids for VKC and suggest a treatment protocol according to our clinical experience. METHODS: This retrospective, nonrandomized case series enrolled 85 patients with VKC. Patients were classified clinically according to severity (mild, moderate, severe) and were treated according to a suggested protocol. Analysis was made according to treatment received: tacrolimus ointment as first line treatment (tacrolimus 1st line), tacrolimus ointment after topical steroid drops treatment (tacrolimus 2nd line) and topical steroid drops or artificial tears alone (topical steroid and tears group). RESULTS: Significant improvements in clinical signs and symptoms were achieved under tacrolimus treatment 14 months in the moderate group and 5 months in the severe group. The longest duration of treatment was for tacrolimus 2nd line group (p = 0.031) and the mean number of visits in the clinic was the highest. The mean number of topical treatments per day was higher in the topical steroid and tears group (2.6 times) than in the two tacrolimus groups (1.3 times for both). The mean time needed to achieve disease remission or relief did not differ between the tacrolimus 1st line and 2nd line groups. CONCLUSION: Tacrolimus treatment is effective and safe for VKC. Tacrolimus as 1st line treatment may be preferred for severe cases, for faster disease remission compared to tacrolimus as 2nd line treatment; and with fewer topical treatments per day compared to topical steroids.

[MATERNAL SERUM ANGIOGENIC FACTORS AS AN AIDING TOOL FOR SCREENING WOMEN WITH SUSPECTED PREECLAMPSIA NEAR DELIVERY - INITIAL DATA AND AN ESTIMATED COST-BENEFIT].

INTRODUCTION: Preeclampsia (PE) is a major pregnancy complication, posing considerable morbidity and mortality. The maternal serum angiogenic factors - PlGF and sFlt-1, and their ratio appear to be promising markers to predict PE. Aims: To assess whether the evaluation of PlGF and sFlt-1 adds to the clinical workup of women with suspected PE, and to estimate the cost/benefit. METHODS: We prospectively enrolled pregnant women with suspected PE who were admitted to the Maternal-Fetal Medicine Unit (MFM) at Shamir Medical Center. Pregnancy and delivery records were collected from their computerized electronic medical records. PlGF<150pg/ml and sFlt-1/PlGF>38 measured prospectively were used to predict PE. RESULTS: Of 105 women included, 28 were in the control group with unrelated complications and none developed PE. Among 66 women with suspected PE, 27(41%) developed the syndrome, with a positive predictive value (PPV) of 90.3% for PlGF<150 pg/ml and 88.9% for sFlt-1/PlGFabove 38. Out of 11 women with suspected intrauterine growth restriction (IUGR), six developed the syndrome, and among them, the negative predictive value (NPV) was ~ 90%. CONCLUSIONS: Angiogenic factors are reliable in predicting PE near delivery. Of 8355 annual deliveries, 584 were admitted for suspected PE. The annual test cost was NIS 66,576 (NIS 140 per single test). Cost-saving was NIS 2.18 million, the ratio of cost saved vs. test cost was 32.7. DISCUSSION: The angiogenic factors are efficient and cost-saving in PE prediction near delivery. A larger study is necessary to determine the inclusion of angiogenic factors in the workup for suspected PE.

Reduced Placental CD24 in Preterm Preeclampsia Is an Indicator for a Failure of Immune Tolerance.

INTRODUCTION: CD24 is a mucin-like glycoprotein expressed at the surface of hematopoietic and tumor cells and was recently shown to be expressed in the first trimester placenta. As it was postulated as an immune suppressor, CD24 may contribute to maternal immune tolerance to the growing fetus. Preeclampsia (PE), a major pregnancy complication, is linked to reduced immune tolerance. Here, we explored the expression of CD24 in PE placenta in preterm and term cases. METHODS: Placentas were derived from first and early second trimester social terminations (N = 43), and third trimester normal term delivery (N = 67), preterm PE (N = 18), and preterm delivery (PTD) (N = 6). CD24 expression was determined by quantitative polymerase chain reaction (qPCR) and Western blotting. A smaller cohort included 3-5 subjects each of term and early PE, and term and preterm delivery controls analyzed by immunohistochemistry. RESULTS: A higher expression (2.27-fold) of CD24 mRNA was determined in the normal term delivery compared to first and early second trimester cases. The mRNA of preterm PE cases was only higher by 1.31-fold compared to first and early second trimester, while in the age-matched PTD group had a fold increase of 5.72, four times higher compared to preterm PE. The delta cycle threshold (ΔCt) of CD24 mRNA expression in the preterm PE group was inversely correlated with gestational age (r = 0.737) and fetal size (r = 0.623), while correlation of any other group with these parameters was negligible. Western blot analysis revealed that the presence of CD24 protein in placental lysate of preterm PE was significantly reduced compared to term delivery controls (p = 0.026). In immunohistochemistry, there was a reduction of CD24 staining in villous trophoblast in preterm PE cases compared to gestational age-matched PTD cases (p = 0.042). Staining of PE cases at term was approximately twice higher compared to preterm PE cases (p = 0.025) but not different from normal term delivery controls. CONCLUSION: While higher CD24 mRNA expression levels were determined for normal term delivery compared to earlier pregnancy stages, this expression level was found to be lower in preterm PE cases, and could be said to be linked to reduced immune tolerance in preeclampsia.

MHC-I presentation of peptides derived from intact protein products of the pioneer round of translation.

Among the earliest protein products of most cellular genes are those synthesized during the pioneer round of translation (PRT), a key step in nonsense-mediated mRNA decay (NMD) that allows scanning of new transcripts for the presence of a premature termination codon (PTC). It has been demonstrated that at least some PRT degradation products can be targeted to major histocompatibility (MHC)-I presentation. To gain new insight into this putative PRT-to-MHC-I route, we have assembled 2 pairs of reporter genes so that the 2 genes in each pair encode an identical fusion protein between a model antigenic peptide and enhanced green fluorescent protein (EGFP), one of which harbors a PTC. We expressed these genes in different mouse and human cell lines and confirmed enhanced NMD activity for the PTC(+) gene in each pair by monitoring the effect of cycloheximide on the level of the respective mRNA. We then exploited several strategies for establishing the ratio between level of peptide presentation and total amount of protein product. We consistently observed significantly higher ratios for the PTC(+) mRNAs compared with the PTC(-) ones, pointing to correlation between the turnover of otherwise identical proteins and the fate of their template mRNA. Using confocal microscopy, we showed a clear link between NMD, the presence of misfolded EGFP polypeptides, and enhanced MHC-I peptide presentation. Altogether, these findings imply that identical full-length gene products differing only in 3' noncoding sequences can be differentially degraded and targeted to the MHC-I presentation pathway, suggesting a more general role for the PRT in establishing the MHC-I peptidome.-Weinstein-Marom, H., Hendel, L., Laron, E.

Establishing a Differential Marker Profile for Pregnancy Complications Near Delivery.

OBJECTIVE: The aim of this work was to define a differential marker profile for pregnancy complications near delivery. METHODS: We enrolled pregnant women who were referred to the outpatient pregnancy clinic of the University Medical Center, Ljubljana, Slovenia, due to symptoms of pregnancy complications and women with a history of pregnancy complications attending the high-risk hospital clinic for close surveillance. They were evaluated for prior risk and were tested for biophysical and biochemical markers at the time of enrolment. Biochemical markers included the pro- and anti-angiogenic markers, along with additional previously reported markers of potential value, all tested by various formats of immuno-diagnostics. Biophysical markers included blood pressure, sonographic markers, and EndoPAT. Statistical differences were determined with Kruskal-Wallis and Mann-Whitney tests for continuous parameters, and Pearson χ2 for categorical values. p < 0.05 was considered significant. RESULTS: The cohort included 125 pregnant patients, 31 developed preeclampsia (PE) alone (13 were <34 weeks' gestation), 16 had intrauterine growth restriction (IUGR) alone (12 were <34 weeks), 42 had both IUGR and PE (22 were <34 weeks), and 15 had an iatrogenic preterm delivery (PTD; 6 were <34 weeks). Twenty-one were unaffected and delivered a healthy baby at term. Mean arterial blood pressure and proteinuria were significantly higher in PE and PE+IUGR but not in pure IUGR or PTD. In PE, IUGR, and PE+IUGR, the levels of soluble fms-like tyrosine kinase 1 (sFlt-1) and soluble endoglin (sEng) were significantly higher, while placental growth factor (PlGF) was very low compared to unaffected controls and PTD. PE, IUGR, and PE+IUGR also had a high anti-angiogenic ratio (sFlt-1/PlGF) and a low proangiogenic ratio of PlGF/(sFlt-1+Eng). Levels of inhibin A were significantly higher in pure PE across subgroups but had many extreme values, which made it a poor differentiator. Higher uterine artery Doppler pulsatility indexes were detected in PE, IUGR, and PE+IUGR, with similar resistance indexes and peaks of systolic velocity. A significantly different marker level between PE and IUGR was found using arterial stiffness that was 10 times higher in PE; concurrently with an increase of the reactive hyperemia index, both were accompanied by a slight increase in placental protein 13. Higher tumor necrosis factor alpha (TNFα) differentially identified iatrogenic very early PTD (<34 weeks). CONCLUSION: Arterial stiffness can serve as a major marker to differentiate PE (with/without IUGR) from pure IUGR near delivery. TNFα can differentiate iatrogenic early PTD from other complications of pregnancy and term IUGR.

Postnatal administration of leptin antagonist mitigates susceptibility to obesity under high-fat diet in male αMUPA mice.

Perturbations in postnatal leptin signaling have been associated with altered susceptibility to diet-induced obesity (DIO) under high-fat-diet (HFD), albeit with contradicting evidence. Previous studies have shown that alpha murine urokinase-type plasminogen activator (αMUPA) mice have a higher and longer postnatal leptin surge compared with their wild types (WTs) as well as lower body weight and food intake under regular diet (RD). Here we explored αMUPA's propensity for DIO and the effect of attenuating postnatal leptin signaling with leptin antagonist (LA) on energy homeostasis under both RD and HFD. Four-day-old αMUPA pups were treated on alternate days until postnatal day 18 with either vehicle or LA (10 or 20 mg·day-1·kg-1) and weaned into RD or HFD. Compared with RD-fed αMUPA males, HFD-fed αMUPA males showed higher energy intake, even when corrected for body weight difference, and became hyperinsulinemic and obese. Additionally, HFD-fed αMUPA males gained body weight at a higher rate than their WTs mainly because of strain differences in energy expenditure. LA administration did not affect strain differences under RD but attenuated αMUPA's hyperinsulinemia and DIO under HFD, most likely by mediating energy expenditure. Together with our previous findings, these results suggest that αMUPA's leptin surge underlies its higher susceptibility to obesity under HFD, highlighting the role of leptin-related developmental processes in inducing obesity in a postweaning obesogenic environment, at least in αMUPA males. This study therefore supports the use of αMUPA mice for elucidating developmental mechanisms of obesity and the efficacy of early-life manipulations via leptin surge axis in attenuating DIO.

Radial versus femoral approach for saphenous vein grafts angiography and interventions.

BACKGROUND: Coronary angiography and intervention to saphenous venous grafts (SVGs) remain challenging. This study aimed to investigate the feasibility and safety of the radial approach compared to femoral access in a large cohort of patients undergoing SVG angiography and intervention. METHODS: Data from 1,481 patients from Canada, United States, and Spain who underwent procedures between 2010 and 2016 were collected. Patients must have undergone SVG coronary angiography and/or intervention. Demographics, procedural data, and in-hospital complications were recorded. RESULTS: Procedures were undertaken by either the radial (n = 863, 211 intervention) or femoral (n = 618, 260 intervention) approach. The mean number of SVGs per patient was similar between groups (radial 2.3 ± 0.7 vs femoral 2.6 ± 1.1, P = .61), but the radial group required a fewer number of catheters (2.6 ± 1.7 vs 4.1 ± 1.1, P < .001). Fluoroscopy time was comparable between groups, and there was a trend toward lower contrast volume in the radial group (P = .045). Overall, the total dose of heparin was significantly higher in the radial group (P < .001); however, radial patients experienced significantly less access-site bleeding complications (P < .001). Outpatients undergoing radial SVG interventions had a higher likelihood of a same-day discharge home (P < .001). CONCLUSIONS: Radial access for SVG angiography and intervention is safe and feasible, without increasing fluoroscopy time. In experienced centers, radial access was associated with fewer catheters used, lower contrast volume, and lower rate of vascular access-site bleeding complications. Moreover, outpatients undergoing SVG percutaneous coronary intervention though the radial approach had a higher likelihood of a same-day discharge home.

Predicting the Risk to Develop Preeclampsia in the First Trimester Combining Promoter Variant -98A/C of LGALS13 (Placental Protein 13), Black Ethnicity, Previous Preeclampsia, Obesity, and Maternal Age.

BACKGROUND: LGALS13 (placental protein 13 [PP13]) promoter DNA polymorphisms was evaluated in predicting preeclampsia (PE), given PP13's effects on hypotension, angiogenesis, and immune tolerance. METHODS: First-trimester plasma samples (49 term and 18 intermediate) of PE cases matched with 196 controls were collected from King's College Hospital, London, repository. Cell-free DNA was extracted and the LGALS13 exons were sequenced after PCR amplification. Expression of LGALS13 promoter reporter constructs was determined in BeWo trophoblast-like cells with luciferase assays. Adjusted odds ratio (OR) was calculated for the A/A genotype combined with maternal risk factors. RESULTS: The A/A, A/C, and C/C genotypes in the -98 promoter position were in Hardy-Weinberg equilibrium in the control but not in the PE group (p < 0.036). The dominant A/A genotype had higher frequency in the PE group (p < 0.001). The A/C and C/C genotypes protected from PE (p < 0.032). The ORs to develop term and all PE, calculated for the A/A genotype, previous PE, body mass index (BMI) >35, black ethnicity, and maternal age >40 were 15.6 and 11.0, respectively (p < 0.001). In luciferase assays, the "-98A" promoter variant had lower expression than the "-98C" variant in non-differentiated (-13%, p = 0.04) and differentiated (-26%, p < 0.001) BeWo cells. Forskolin-induced differentiation led to a larger expression increase in the "-98C" variant than in the "-98A" variant (4.55-fold vs. 3.85-fold, p < 0.001). CONCLUSION: Lower LGALS13 (PP13) expression with the "A" nucleotide in the -98 promoter region position (compared to "C") and high OR calculated for the A/A genotype in the -98A/C promoter region position, history of previous PE, BMI >35, advanced maternal age >40, and black ethnicity could serve to aid in PE prediction in the first trimester.

Parents reported higher satisfaction rates when children recognised hospital staff from photographs placed in prominent locations.

AIM: Improved communication with staff during a child's hospitalisation is an important determinant of family satisfaction. We examined whether displaying staff photographs in prominent locations would help children and their parents or guardians to recognise staff and whether this enhanced identification would improve parental satisfaction with their child's hospitalisation. METHODS: No photographs were displayed during the first part of the study. During the second part of the study, staff photographs were placed in prominent locations throughout the paediatric ward. Parents filled in a satisfaction questionnaire on discharge, and the children and their parents were asked how many staff members they could name. RESULTS: The children named a significantly larger number of staff members in phase two than phase one, while the parents' score was unchanged. Overall parental satisfaction was significantly higher in phase two. The parent's age, the duration of the child's hospitalisation and taking part in phase two of the study were significant predictors of parental satisfaction. CONCLUSION: When children were more able to recognise and name hospital staff, this indirectly improved parental satisfaction, even if the number that parents could identify remained unchanged. Displaying staff photographs is a simple way of increasing parental satisfaction during a child's hospitalisation.

Can Staining of Damaged Proteins in Urine Effectively Predict Preeclampsia?

OBJECTIVES: To assess Congo red urine test in the first trimester for preeclampsia (PE) prediction. SAMPLE: A Congo red test was developed with a cohort of 81 pregnant women in Bnai Zion hospital, Israel, at 26-41 weeks of gestation (12 PE cases). The test was then applied to a first-trimester cohort of 642 women at King's College Hospital, UK (105 subsequently developed PE, 21 early, i.e., <34 weeks; 537 controls). METHODS: Urine samples were spotted onto nitrocellulose membranes, stained with Congo red, de-stained, dried and quantified with imager and densitometry. RESULTS: At PE signs and symptoms, the detection rate (DR) was 93% and the false-positive rate (FPR) 4%. However, with first-trimester urine samples, the DR was 33.3%, 16.1% and 20% for early, late and all PE cases, respectively, at 12.8% FPR. The odds ratio (OR) for PE by Congo red alone (including adjusted OR) was superior to body mass index and mean arterial blood pressure (MAP) but inferior to previous PE and black ethnicity. Combining all five parameters generated an adjusted OR of 13.92 for PE (p < 0.001). CONCLUSION: Congo red urine test at PE verifies the disorder. In the first trimester, it adds accuracy for PE prediction in obese, black women, who had previous PE and over-average MAP.

Placental Protein 13 Administration to Pregnant Rats Lowers Blood Pressure and Augments Fetal Growth and Venous Remodeling.

Reduced first-trimester concentrations of placental protein 13 (PP13) are associated with subsequent development of preeclampsia, a major pregnancy disorder. We previously showed that PP13 has a vasodilatory effect, reduces blood pressure and augments expansive remodeling of the uteroplacental vasculature in pregnant rats. In this study, slow-release osmotic pumps were implanted in gravid rats (on day 8) to provide 1 week of PP13 supplementation. Treatment was associated with a reversible blood pressure reduction that returned to normal on day 15. In addition, PP13 caused venous expansion that is larger in the venous branches closer to the placenta. Then, it increased placental and pup weights. Similar administration of a truncated PP13 variant (DelT221) that is unable to bind carbohydrates (a rare spontaneous mutation associated with a high frequency of severe early preeclampsia among Blacks in South Africa) produced a hypotensive effect similar to the full-length molecule, but without venous remodeling and increased placental and pup weights. These results indicate the importance of PP13 carbohydrate binding for inducing vascular remodeling and improving reproductive outcome. Future studies are needed to determine whether beneficial effects would be evident in animal models of preeclampsia or in women predisposed to the development of preeclampsia.

Acupuncture for posttonsillectomy pain in children: a randomized, controlled study.

BACKGROUND: Surgeons have searched for the technique or medication that will produce a 'painless tonsillectomy'; however, this seems to be an impossible goal. Previous studies have shown that perioperative acupuncture may be a useful adjunct for acute postoperative pain and that acupuncture, in addition to nonsteroidal anti-inflammatory drugs, is effective in adults for the treatment of postoperative swallowing pain after tonsillectomy. Acupuncture has been shown to be safe in children. A retrospective review of acupuncture for posttonsillectomy pain in juvenile patients showed a significantly reduced pain score immediately after treatment. AIM: To examine whether acupuncture, in addition to conventional analgesic treatment, will be effective in the treatment of posttonsillectomy pain in children. METHODS: We conducted a randomized, controlled, single-blinded study comparing conventional postoperative analgesic treatment with the same regime plus acupuncture to assess whether postoperative treatment of children aged 3-12 years undergoing tonsillectomy with acupuncture will reduce pain and to examine possible unwanted effects of this treatment. RESULTS: Sixty children were recruited and randomly divided into a study group and a control group. The results indicate that in the study group, there was less pain, less analgesic drug consumption, and higher patient/parent satisfaction with analgesic treatment scores. No adverse effects were recorded. CONCLUSIONS: Acupuncture, in addition to conventional analgesic treatment, is an effective treatment for posttonsillectomy pain. Acupuncture is safe and well received by children and their parents.
