Machine-learning based calculator for personalized risk following ST-elevation myocardial infarction

Abstract Background Despite recent advancements in the management of patients with ST-elevation myocardial infarction (STEMI), a high risk for adverse events remains during the first year following the event. There are several risk scores which estimate the risk of major adverse cardiac events (MACE) following STEMI. However, the most established risk scores are not contemporary, their diagnostic accuracy ranges across populations, and they are far from being personalized. Purpose We aimed to develop a machine learning (ML)-based calculator to provide patients and physicians with a personalized prognostic tool based on modern-world data to determine outcomes for patients following STEMI. Our goal was to predict mortality within 1-year post-STEMI and contribute personalized recommendations to reduce the risk of events. Additionally, we aimed to have the calculator provide a personalized risk assessment for each independent variable. Methods We included patients from two large tertiary care centers in Israel and Italy. 2888 patients who suffered STEMI between the years of 2000 – 2020 were included in our training model. Our calculator leveraged CatBoost for supervised machine learning, utilizing gradient boosting on decision trees. The model was subsequently tested on 321 patients from the Israeli center and 132 patients from the Italian center. Results The calculator was able to accurately predict 1-year mortality (96.5% accuracy, ROC 0.97 in the Israeli center and 93.2% accuracy, ROC 0.89 in the Italian center). In the full cohort, left ventricular ejection fraction (LVEF) post-STEMI demonstrated the strongest contribution towards predicted outcome with a mean Shapley value (SHAP) of 0.978, with lower EFs correlating to higher likelihood of one-year mortality (figures 1 and 2). Other strong contributing factors were identified, including glomerular filtration rate (GFR), age, and Killip classification, with mean SHAPs of 0.580, 0.571, and 0.563, respectively. Importantly, the algorithm was designed to also output a personalized assessment of risk for each patient based on their individual variables. Conclusion ML-derived STEMI calculators can determine which risk factors and variables provide highest predictive value in determining outcomes in a personalized manner. They can be leveraged for high-accuracy prognostication and provide guidance for physicians and patients after STEMI.

Steps Toward Decreasing Maternal Alcohol Consumption in Israel: Nationwide Trends During a Decade.

Prenatal alcohol exposure poses a substantial risk to fetal development. Efforts were made in 2011-2020 to increase public awareness of and prevent alcohol consumption during pregnancy. We conducted a cross-sectional survey in Israel of pregnant women's alcohol consumption from January 2021 through June 2023 and compared our results with the results of a survey conducted during 2009-2010 to assess changes over time. We conducted cross-sectional surveys at 3 public hospitals in central and northern Israel. Surveyors visited hospitals twice weekly and used a questionnaire consistent with one used in 2009-2010 that focused on alcohol consumption 3 months before pregnancy and during pregnancy. We conducted a stratified analysis of the prevalence of alcohol consumption during pregnancy by demographic characteristics. We also used a multivariable logistic regression model to examine variables associated with receiving guidance on alcohol consumption during pregnancy. Of 1915 women in the 2021-2023 survey (mean [SD] age, 30.8 [5.6] y), 1204 (62.9%) reported never consuming alcohol before pregnancy and 1708 (89.2%) reported no alcohol consumption during pregnancy. During pregnancy, 157 (8.2%) women reported consuming alcohol weekly or less, 12 (0.6%) more frequently, and 52 (2.7%) binge drinking. We found a significant decrease in alcohol consumption during pregnancy in 2021-2023 as compared with 2009-2010 (odds ratio, 0.68; 95% CI, 0.52-0.88; P = .03). Predictors of alcohol consumption during pregnancy included alcohol consumption before pregnancy, parity, and smoking. Significantly more women in the 2021-2023 sample (n = 569; 29.7%) than in the 2009-2010 sample received guidance on alcohol consumption during pregnancy (P < .001). Educational efforts should continue to increase awareness of the risks of prenatal alcohol exposure in the general population and among health professionals.

Trends in Israeli clinical trials registration “MyTrial”

BackgroundClinical trial registration is critical for research transparency and integrity. Since 2005, the Declaration of Helsinki has required prospective registration of trials before subject recruitment. In Israel, the MyTrial registry was established in 2015 to register interventional trials and became mandatory in 2016 for ethical approval. The study aimed to analyze the registration practices, challenges, and trends in clinical trial registration in Israel using the local registry “MyTrial”.MethodsA total of 3,895 clinical trial records from 2011 to December 2022 were retrieved from the MyTrial platform and subjected to descriptive analysis.ResultsA significant increase occurred from 2016 to 2021 due to mandated registration, with a peak in 2020 (733 trials) and a decrease in 2022 (462 trials), likely due to COVID-19. Most of the trials included drugs (56%) or medical devices (33%). Geographically, 53% were from central Israel. Only 39% of the patients were registered at both MyTrial and ClinicalTrials.gov. 65% had no blinding. 47% featured unregistered products. 56% had not started recruitment. Since 2016, the number of advanced therapy trials has steadily increased, reaching 19 in 2022. There are gaps between registered trials and official government reports.ConclusionThese findings provide valuable insights into the current landscape of clinical trial registration in Israel and highlight the need for improvements in compliance with prospective registration and adherence to the WHO-ICTRP standards.

Eurasian Sparrowhawk (Accipiter nisus) Population Trend and Productivity in Central Israel

ABSTRACT Israel’s nationwide multiyear campaigns, particularly in the late 18th and early 19th centuries, involved deforestation and the development of natural areas for agriculture and human settlement, and resulted in the local extirpation of several animal species. However, reforestation began in the 1940s and promoted the resurgence of extirpated populations. One species that has benefited from these landscape changes is the Eurasian Sparrowhawk (Accipiter nisus). Based on the analysis of population trends in the Judea region (central Israel), we found that this species’ abundance increased by 8.9% over a 5-yr study period (2006–2010). We also found that hatching day was the only reproductive parameter in our study area that varied significantly among years. This breeding parameter depended on three habitat characteristics: (1) the height of the nest; (2) the amount of mixed forest with sparse cover in the area around the nest; and (3) the amount of herbaceous vegetation around the nest. Hatching began earlier in higher nests, and hatching began later in nests surrounded by a high percentage of mixed forest and herbaceous vegetation. However, productivity was independent of the habitat type surrounding the nest site. Our descriptive analysis of prey types suggested that most species in the prey remains and pellets likely came from outside the forest, typically from open areas such as agricultural fields, water reservoirs, or aquaculture ponds. Further, only three species dominated the prey remains and pellets below the nests. We documented reproductive parameters and changes in population size during the early years of this population increase. We predict that the population will continue to thrive and spread into the surrounding areas, as there have been no significant changes in land management in the study area over the past 13 yr.

Transformations in BPH Surgical Practices: A Longitudinal Study of Trends and Predictions.

The workload for BPH surgery is expected to rise with an increase in life expectancy and a growing population. Surgical modalities for BPH have evolved, shifting towards minimally invasive transurethral procedures. This study aims to investigate the trends in BPH surgical procedures across medical centers in Israel. Data from seven academic medical centers in Israel from 2010 to 2022 were analyzed. Procedures included open prostatectomy, transurethral prostatectomy (TURP), laser enucleation of the prostate (HoLEP), and photovaporization of the prostate (PVP). Statistical analyses were employed, including t-tests, ANOVA, and ARIMA models. Over 12 years, 13,478 BPH procedures were performed. TURP was the most common (72%), followed by open surgery (12%), HoLEP (12%), and PVP (3%). Annual procedures increased by approximately 5% each year, with a cumulative surge of 63% cases by 2022. The average patient's age remained stable. TURP and HoLEP showed continual growth, while open surgery declined. HoLEP exhibited a shorter length of hospital stay compared to other modalities. Predictive models suggest open prostatectomy will cease within two years, while TURP and HoLEP will continue to rise. This study highlights a significant increase in BPH surgical procedures over time, with a notable preference for TURP and HoLEP. The findings emphasize the importance of size-independent techniques like HoLEP for optimal healthcare management in the future.

Utilization Patterns of Glucagon Like Peptide-1 Receptor Agonists Prior to Bariatric and Metabolic Surgery: A Multicenter Study

BackgroundGlucagon-like-peptide-1 receptor agonists (G1RA) have gained popularity as a treatment for weight loss in patients who are overweight or obese, but their utilization patterns and impact on candidates for metabolic and bariatric surgery (MBS) remain understudied. ObjectiveWe aimed to investigate the prevalence, characteristics, and outcomes of patients with a history of G1RA utilization among MBS candidates. SettingFive high-volume MBS centers in Israel. MethodsData were collected retrospectively from February 1st, 2023, to September 30th, 2023. Demographic, clinical, and treatment data were analyzed to assess a history of G1RA use, associated factors, adverse events, and treatment outcomes. Results434 MBS candidates were included in the study. A history of G1RA utilization was obtained in 275 (63%) MBS candidates, with Liraglutide and Semaglutide being the most commonly used agents. Younger age, type 2 diabetes mellitus, dyslipidemia, and no previous MBS history were associated with a higher rate of G1RA utilization. With these medications, median maximal weight loss was 5.38 kg, and mean duration of use was 19 weeks. Patients using G1RA for ≥6 weeks experienced significantly greater weight loss compared to those using it for shorter periods (6.3±6.43 vs 1.65±1.69 ;p<0.001). GI-related adverse events were reported in 57.8% of patients. Over 95% of patients discontinued G1RA due to insufficient weight loss and/or adverse effects. Patients reaching the maximal recommended dose exhibited significantly greater weight loss vs patients who did not reach it for both Liraglutide (5.9±4.98 kg vs. 3.9±5.53 kg; p=0.03) and Semaglutide (6.5±7.8 kg vs. 2.5±3.8 kg; p=0.016). ConclusionPre-MBS G1RA utilization and failure are prevalent among MBS candidates. Our study underscores the need for further research to understand the role of G1RA therapy in obesity management and the development of guidelines for its appropriate use in MBS candidates.

Lomitapide for the treatment of paediatric patients with homozygous familial hypercholesterolaemia (APH-19): results from the efficacy phase of an open-label, multicentre, phase 3 study

Homozygous familial hypercholesterolaemia (HoFH) is a rare inherited disorder characterised by extremely high concentrations of LDL cholesterol, leading to early-onset atherosclerosis. Lomitapide is an orally administered microsomal triglyceride transfer protein (MTP) inhibitor that effectively lowers LDL cholesterol and is approved for adults with HoFH. We aimed to investigate the efficacy and safety of lomitapide in paediatric patients with HoFH receiving standard-of-care lipid-lowering therapy. APH-19 is an open-label, single-arm, phase 3 trial performed at 12 study centres in Germany, Israel, Italy, Saudi Arabia, Spain, and Tunisia. A 6-week run-in period was followed by a 24-week efficacy phase and an 80-week safety phase. Patients aged 5-17 years, on stable lipid-lowering therapy, with HoFH diagnosed using the criteria from the 2014 European Atherosclerosis Society Consensus Panel on HoFH were titrated to maximum tolerated doses of oral lomitapide, starting at 2 mg (patients aged 5-15 years) or 5 mg (patients aged 16-17 years). The primary endpoint was the percentage change from baseline to week 24 in LDL cholesterol, which was assessed in patients who had received at least one dose of lomitapide, and who had a baseline and at least one post-baseline measurement. The secondary outcomes were the percentage change from baseline at week 24 in total cholesterol, non-HDL cholesterol, VLDL cholesterol, apolipoprotein B, triglycerides, and lipoprotein(a). Safety was assessed in patients who received at least one dose of study drug. This study is registered with ClinicalTrials.gov, NCT04681170. Between Dec 20, 2020, and Oct 16, 2022, 43 patients were included and treated (24 [56%] were female and 19 [44%] were male, and median age was 10·7 years [7·0-14·0]). Mean change from baseline in LDL cholesterol at week 24 was -53·5% (95% CI -61·6 to -45·4, p<0·0001). Mean percentage reductions were observed at week 24 for non-HDL cholesterol (-53·9%, 95% CI -61·7 to -46·1, p<0·0001), total cholesterol (-50·0%, 95% CI -57·6 to -42·4, p<0·0001), VLDL cholesterol (-50·2%, -59·1 to -41·2, p<0·0001), apolipoprotein B (-52·4%, -60·3 to -44·5, p<0·0001), triglycerides was -49·9% (-58·8 to -41·0, p<0·0001), and lipoprotein(a) (-11·3%, -32·9 to 10·3 [in 21 patients with measurements in mg/dL]; -23·6%, -38·2 to -9·0 [in 22 patients with measurements in nmol/L]; p=0·0070 combined). Adverse events were mostly mild, and gastrointestinal and hepatic in nature. Adverse events of special interest were reported for five (12%) patients (gastrointestinal in two patients and hepatic in three). One serious treatment-emergent adverse event was reported (also classed as an adverse event of special interest): an increase in hepatic enzymes, resulting in two dose interruptions, two dose reductions, and a repeated dose escalation. Lomitapide provided a significant, clinically meaningful LDL cholesterol reduction and has the potential to be an efficient, LDL receptor-independent option for paediatric patients with HoFH.

The Epidemiology of PCR-Confirmed Cutaneous Leishmaniasis in Israel: A Nationwide Study.

Leishmaniasis, mainly cutaneous leishmaniasis (CL), is endemic in Israel. In recent years, the diagnosis of leishmaniasis has transitioned to a molecular diagnosis. To summarize all cases of leishmaniasis and the identified species seen in Israel based on molecular diagnosis. A retrospective study was performed of patients diagnosed with leishmaniasis between January 2017 and December 2022. All five medical centers in Israel in which Leishmania diagnosis is performed were included: Soroka, HaEmek, Hadassah, Rambam, and Sheba, all utilized molecular diagnostic methods. Data on the annual number of cases, species, age, and gender were retrieved. During the years 2017-2022, a total of 4168 cases of leishmaniasis were diagnosed, which corresponds with ~7/100,000 inhabitants. L. (L.) major and L. (L.) tropica accounted for 84% and 14%, respectively. During the years 2020-2021, L. (L.) infantum emerged as a new form of cutaneous disease [2.7% of cases during this period]. Visceral L. (L.) infantum was found in five cases. Imported New World leishmaniasis accounted for 1% of the cases. L. (L.) major affected more males (67%) while L. (L.) tropica commonly affected more children and caused more facial lesions. The mean annual number of cases during these years is ~700. The dominant species is L. (L.) major. Since 2020, cutaneous L. (L.) infantum is an emerging infection in Israel.

Beyond Magic: Fostering Literacy Resilience in Diverse Classrooms through Home-Based Approaches.

The classrooms in Israel are very diverse, with students differing in learning styles, their handling of literacy tasks, personal and socioeconomic backgrounds, and more. These differences significantly impact the curriculum aimed at promoting literacy resilience, explicit teaching processes in the classroom, and imparting metacognitive strategies and actions to overcome learning difficulties. This qualitative-interpretative study reveals the pedagogical perceptions, challenges, and coping strategies of fourteen Hebrew teachers in five elementary schools in central Israel regarding integrating home literacy in language lessons and cultivating literacy resilience among their students. The research data were collected through in-depth interviews with the teachers. The analysis of the teachers' reports reveals two main perceptions regarding literacy resilience: (1) Literacy resilience is a tool for life; (2) Home literacy significantly contributes to fostering literacy resilience. Furthermore, cultivating literacy resilience presents three significant challenges for the teachers: (1) Teaching in a heterogeneous classroom, (2) Encouraging parental involvement, and (3) Fostering independent learners. To cultivate literacy resilience in a heterogeneous classroom, teachers must be sensitive to each student's unique needs and plan teaching-learning processes based on principles of self-directed learning and peer dialogue. They must establish a personal-emotional connection that is a significant anchor for the students and outlines a path for integrating and strengthening the sense of competence in handling literacy tasks. It was also found that parental involvement is a significant factor influencing the cultivation of literacy resilience, and teachers undertake various actions to increase their level of involvement. This study adds an essential layer to the body of knowledge regarding the understanding of the factors affecting the development of pedagogical literacy perceptions that promote the integration of home literacy in the classroom. These perceptions may promote the nurturing process of literacy resilience among students from various cultures, accepting and understanding them. In this way, we can attempt to address literacy and language challenges in Israel.

COVID‐19 as a financial opportunity for the millennials

AbstractThis study aims to examine how COVID‐19 affects the views of the members of Generation Y (millennials) regarding their financial future. The literature often describes and perceives millennials as spoiled, unindustrious and lacking in focus. This research uses data collected via interviews with 20 participants in their 20s and 30s who live in the centre of Israel. The participants were recruited by a polling company during September 2021. The study finds that participants’ behaviour during this crisis was more level‐headed than in the past due to their understanding that the future is uncertain and they can rely on no one other than themselves. The study's participants reported making decisions to improve their financial future. Most view COVID‐19 as a rare opportunity to make changes in their lives, primarily in their finances and their employment. This is reflected by current choices intended to create a better financial future for themselves. The main finding of this research is that following the shock caused by the COVID‐19 pandemic, millennials have been forced to take care of themselves. They understand that if their parents get sick, they will not be able to continue making a living and will be unable to provide financial help to their children.

Greenness Exposure and Mortality Risk in a Cardio-Oncologic Population.

Knowledge is lacking on the relationship between greenness and mortality in cancer survivors who experience coronary artery disease (CAD), a cardio-oncologic population. We aimed to investigate the association between residential greenness exposure and all-cause mortality in a cardio-oncologic population. Cancer survivors undergoing percutaneous coronary intervention at the Rabin Medical Center in Israel between 2004 and 2014 were included in the study. Clinical data were collected from medical records during index hospitalization and from the Israeli National Cancer Registry. Residential greenness was estimated by the normalized difference vegetation index (NDVI), a satellite-based index derived from Landsat imagery at a 30-meter spatial resolution, with larger values indicating higher levels of vegetative density (ranging between -1 to 1). Mortality follow-up data were obtained through the end of 2021. Cox models were used to assess the hazard ratios (HRs) for all-cause mortality per 1SD increase in NDVI. Among 1,331 patients analyzed [mean (SD) age, 75.6 (10.2) years, 373 (28%) females], the mean (SD) NDVI within a 300-meter radius was 0.12 (0.03). During a median follow-up period of 12.0 (IQR 9.2-14.7) years, 883 (66%) participants died. After adjustment for potential confounding factors, including residential socioeconomic status, air pollution, and smoking, NDVI was inversely associated with mortality hazard [HR (95% CI) = 0.93 (0.86, 0.99); p=.042]. The association was stronger among individuals with more recently (<10 years) diagnosed cancer [HR (95% CI) = 0.89 (0.81, 0.98); p=.019]. In a cohort of cardio-oncologic patients, greenness was independently associated with lower mortality.

One Country, Different Reactions- How did the Gay Community in Israel Respond to the New Mpox Threat?

Mpox affected mainly men who have sex with men (MSM). This study aimed to assess MSM's response to the threat, and compare MSM living in central Israel vs. its periphery. Data were collected by anonymous electronic surveys between September and October 2022 through a geospatial application ("Grindr"). Of the 665 MSM participants, 221 (33.2%) were vaccinated against mpox. In the multivariate analysis, living in central Israel, being in steady relationships, HIV infection, PrEP use, noticing suspicious skin lesions, and changing sexual behavior predicted vaccination. Of all participants, 317 (47.6%) changed their sexual behavior. In the multivariate analysis, living in central Israel, engaging in risky sexual behavior and being vaccinated against mpox predicted sexual behavior change. Of the 444 participants who were not vaccinated, 245 (55.1%) lived in peripheral regions of Israel. Those who lived in the periphery were less likely to get vaccinated or change their sexual behavior compared with MSM who lived in central Israel. Although the study was limited in size and the study population was relatively homogeneous, MSM perceived mpox as a potential threat on health, and almost 50% changed their sexual behavior and nearly one-third were vaccinated against mpox. The trend was mainly observed in MSM who were at high risk to acquire mpox and those who lived in central Israel.

Traumatic experiences, quality of life, and organizational commitment among midwives: A cross-sectional study.

The work of midwives is emotionally challenging. Midwives share moments of joy, when a baby is born, and attend complex events of loss and trauma. Exposure to childbirth complications, emergencies, and loss can affect their professional quality of life and functioning. This aspect of midwives' practice has not been sufficiently researched. To examine the associations between exposures to traumatic events, post-traumatic symptoms, and personal resilience with professional quality of life and organizational commitment among hospital midwives. Participants in this cross-sectional study conducted in 2020 included 131 midwives from three large hospitals in central Israel. Data were collected using a structured self-administered questionnaire that examined socio-demographic characteristics, exposure to traumatic events during childbirth, personal resilience, post-traumatic symptoms, professional quality of life, and organizational commitment. The three most traumatic events for midwives were: neonatal death or feared death, maternal death or feared death, and stillbirth. The more frequent the exposure to traumatic events, the more numerous and intense the post-traumatic symptoms. The more numerous and intense the post-traumatic symptoms, the higher the level of professional burnout and compassion fatigue and the lower the compassion satisfaction. Higher compassion satisfaction and lower professional burnout were associated with higher organizational commitment. Personal resilience, country of birth, post-traumatic symptoms, and organizational commitment predicted compassion satisfaction. Midwives' exposure to traumatic events is associated with the onset of post-traumatic symptoms, impaired professional quality of life, and reduced organizational commitment, and is accompanied by burnout and compassion fatigue. There is a need to address this issue in training programs and to develop organizational support and policies to improve midwives' well-being and quality of care.

Iron deficiency anemia among infants: a retrospective cohort study

Postnatal iron deficiency, especially from ages 6 to 24 months, has long-term consequences lasting into adolescence and adulthood. We aimed to characterize iron deficiency anemia among infants from one central Israeli district by demographic and laboratory parameters. A retrospective chart review was performed on all infants from a single district who had undergone a complete blood count as part of a routine survey for iron deficiency anemia during 2010–2021. Data retrieved included hemoglobin levels, mean corpuscular volume, and demographic features: sex, sector (non-ultraorthodox Jew, ultraorthodox Jew, and Arab), socioeconomic status, and type of residence. The study group comprised 101,650 infants, aged 9 to 18 months. Iron deficiency anemia, defined as a hemoglobin level <11 g/dL and mean corpuscular volume <70 fl was observed in 4296 (4.2%) of the study infants. Iron deficiency anemia was more prevalent among Arab and ultraorthodox Jewish infants, than non-ultraorthodox Jewish infants (6.6% vs. 6% vs. 3%, respectively). It was also more prevalent among infants of low socioeconomic status, and relatively common among infants of rural residence. We identified two specific sub-populations at risk of developing iron deficiency anemia: Arab and ultraorthodox Jewish infants. We recommend enhancing the nationwide intervention program for both clinicians and parents, thereby treating iron deficiency anemia promptly to avoid short- and long-term deleterious health consequences.

A simple analytical method to estimate runoff generation and accumulation

The study of runoff formation in semiarid regions relies generally on the solution of Richards equations using numerical approaches such as those provided by Hydrus-1D. We demonstrate here that a Simple Analytical Method (SAM) could be easily applied to estimate areas under flooding risk, under different soil and rainfall conditions, without the need to run burdensome numerical models. The impact of antecedent soil moisture condition was expressed quantitatively, conferring to SAM a predictive capability based on a-priori information on soil properties, rainfall characteristics, and initial conditions. The SAM was applied to the Shikma catchment, in the center of Israel, to illustrate its capability to estimate the spatial distribution of time of runoff occurrence and runoff coefficient for a prescribed rainfall event. The results suggest that SAM can be used as part of early warning systems of flood risks. Radars, carried by satellites and drones, can be used to provide refined data on rainfall intensity and soil surface initial conditions. SAM could be then coupled with these remotely sensed data to improve runoff initiation and accumulation estimates, thus reducing the time interval required to reach operational decisions regarding potential floods and inundations, and related water erosion hazards.

Infracoccygeal/transperineal window: new method to prenatally diagnose and classify level of anal atresia.

To introduce a two-dimensional sonographic method to assess the fetal anus, and to evaluate the feasibility of this method to diagnose anal atresia prenatally and identify the presence or absence of anoperineal fistula (in males) and anovestibular fistula (in females). This was an observational study of suspected cases of anal atresia referred to a single center in Israel between August 2018 and October 2023. In addition to conventional evaluation of the perineum in the axial plane, fetuses referred to our center for suspected malformation were scanned with a new method termed the 'infracoccygeal/transperineal window'. This window consisted of a midsagittal view of the fetal pelvis, including the distal rectum and the anal canal. Normal anatomy was confirmed when the anal canal was continuous with the rectum and terminated at the expected location on the perineum. In female fetuses, the normal anal canal runs parallel to the vaginal canal and diverges posteriorly, terminating at the perineal skin, distant from the vestibule. In male fetuses, the normal anal canal diverges posteriorly in relation to the corpora cavernosa, terminating at the perineal skin, distant from the scrotum. High anal atresia was identified when a blind-ending rectal pouch was demonstrated in the pelvis without a fistula to the perineum or vestibule. Low anal atresia was determined when a rectal pouch was continuous with an anteriorly deflected fistula. In females, the fistula converges with the vaginal canal, terminating at the vestibule; in males, the fistula deflects anteriorly, terminating at the base of the scrotum. Postnatally, the diagnosis and type of anal atresia were confirmed through physical examination with direct visualization of the fistula, radiographic studies, surgical examination and/or postmortem autopsy. Of the 16 fetuses diagnosed prenatally with anal atresia, eight were suspected to have low anal atresia and eight were suspected to have high anal atresia. The median gestational age at diagnosis was 23 (range, 14-37) weeks. All cases showed additional structural malformation. Eleven patients opted for termination of pregnancy, of which four had low anal atresia and seven had high anal atresia. Postnatal confirmation was not available in four cases due to curettage-induced mutilation or in-utero degradation following selective termination of the affected twin, leaving 12 cases for analysis, of which seven were diagnosed with low anal atresia and five with high anal atresia. In these 12 cases, all prenatal diagnoses were confirmed as correct, rendering 100% sensitivity and 100% specificity in this high-risk fetal population. The infracoccygeal/transperineal window is an effective method to detect and classify the level of anal atresia prenatally. This may improve prediction of postnatal fetal continence and optimize prenatal counseling. © 2024 International Society of Ultrasound in Obstetrics and Gynecology.

Beachrock: A chronological benchmark for Late Holocene build-up on the coast of Israel

Beachrock formations are proxies of coastal morphodynamics, and are thus commonly utilized for paleoenvironment interpretations. Linear beachrock outcrops parallel to the shoreline are typical of the Mediterranean coastline of Israel. A new geomorphic and sedimentological analysis of beachrock, integrated with relative and absolute geochronology, characterizes their clastic composition and determines their ages. In-situ beachrock outcrops in the sandy beaches of the Sharon coast of central Israel are composed of quartz sand, shells and shell fragments, and show a significant contribution of fragmented rocks from the coastal cliff. Sections of beachrocks analyzed using portable Optically Stimulated Luminescence (pOSL) provided a relative chronological framework within and between the sections. The results show a moderate optic signal accumulation, indicating a gradual beach build-up during initial beachrock formation stages. Optically Stimulated Luminescence (OSL) ages indicate deposition of unconsolidated beach sediments dated to about 1600–800 years before present (BP). The sediment burial at the former foreshore enabled rapid consolidation in the intertidal zone.

Pandemic of sensitivity to acrylate containing nail cosmetic among young Israeli women? Result of patch testing 2-hydroxyethyl methacrylate in the European baseline series.

2-Hydroxyethyl methacrylate (HEMA) was added into the European baseline series (EBS) in 2019. There is limited data regarding the frequency, relevance, and sources of exposure to HEMA. To investigate the frequency and clinical relevance of positive reactions to HEMA in the EBS in Israel, and explore sources of exposure. Retrospective cohort study that included all patients who underwent patch testing with the EBS in a tertiary center in Israel between 2020 and 2023. Positive reactions to HEMA were stratified by sex, six age groups, and year of study. Sources of exposure to HEMA as well as occupational data were recorded. A total of 1671 consecutive patients underwent HEMA patch testing, with 135 (8.1%) showing positive reactions to HEMA (130 females, 5 males). The prevalence in women (11.0%) was significantly higher compared to men (1.0%) (p < 0.001). Stratification by age and sex revealed the highest frequency of HEMA sensitivity of 16.7% among women younger than 30 years of age, with odds ratio of 2.3 (95%CI: 1.6-3.3, p < 0.001) compared to older women. There was an increase in frequency among women between the years 2022 and 2023 when compared to 2020-2021 (OR 1.7, 95%CI: 1.5-2.1, p < 0.01) attributable to COVID-19 pandemic and social restrictions. Among men the frequency fluctuations over the study period and age categories were nonsignificant. 111 (84%) were judged to be of clinical relevance and nail cosmetics was responsible for 95% of them. Of 111 patients with relevant reaction (110 females, 1 males), 20 (18%) had occupational contact dermatitis (18 nails stylists, 2 dentists). Other culprit products included sanitary pads (n = 4), medical adhesives (n = 3), and paints (n = 2). We report the highest frequency of HEMA sensitivity to date of 8.1%, that was most common among young women and in vast majority of cases was attributable to nail cosmetics. Our findings reflect the popularity of nail cosmetics in Israel as well as the global trend of increasing sensitivity to (meth)acrylates.
