Physician performance scores used to predict emergency department admission numbers and excessive admissions burden

BackgroundOvercrowding in hospitals is associated with a panoply of adverse events. Inappropriate decisions in the emergency department (ED) contribute to overcrowding. The performance of individual physicians as part of the...

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.

Similar Outcomes in Males and Females Undergoing Surgery for Infective Endocarditis.

Background: Sex-based differences in mortality have been previously observed in patients with surgically treated infective endocarditis. We sought to evaluate the risk factors leading to this difference. Methods: A retrospective cohort from three centers in Israel comprising 376 surgically treated patients, comparing short- and long-term mortality rates and risk factors between female and male patients. Results: Compared to male patients, female patients had higher rates of hypertension (62% vs. 48%), higher rates of Gram-negative infections (20% vs. 11%), and more mitral valve replacement (55% vs. 42%). Diabetes and age were the most significant predictors for mortality and did not differ between female and male patients. In-hospital mortality rates did not differ between female and male patients (29% vs. 26%), and the difference in long-term mortality was not statistically significant (46% vs. 36% p = 0.088). Conclusions: No statistical difference was observed in short- and long-term mortality between female and male patients, most likely due to a lack of difference in the rates of important risk factors such as diabetes and age. Mortality rates decreased in the last 10 years, and a good prognosis is observed for patients surviving the initial 30 days after surgery.

Esophageal Atresia with Tracheoesophageal Fistula Is Associated with Consanguinity

Objectives and StudyEsophageal atresia with tracheoesophageal fistula (EA-TEF) is a rare congenital malformation. The incidence of TEF is 1.3-4.6 cases per 10,000 live births. The specific etiology of EA-TEF is unknown. Environmental risk factors, such as maternal medication use and alcohol consumption during pregnancy, are suggested. Genetic factors have also been described, especially among syndromic types, such as Down syndrome, but less among non-syndromic types. The aim of the study is to examine the association between non-syndromic EA-TEF and consanguinity. MethodsA retrospective study comparing the incidence of EA-TEF between low-consanguineous Jewish population and high-consanguineous Bedouin population. All patients were treated at Soroka University Medical Center, the only tertiary medical center in southern Israel. ResultsDuring the years 2000-2022, 579,130 children were born in southern Israel, 386,915 (66.8%) were Jewish, and 192,215 were Bedouin Muslims. A total of 96 patients were diagnosed with EA-TEF, 83 of them were non-syndromic. The incidence of EA-TEF was 1.66 cases per 10,000 live births and was statistically higher among the Bedouin population (3 vs. 0.95 cases per 10,000 live births, P<0.001). The consanguinity rate among the Bedouin group was higher compared with the Jewish (67.8% vs 0% P<0.001). There were no differences in other risk factors. ConclusionThe incidence of EA-TEF is exceptionally higher among the Bedouin population that lives in the same geographic region and has the same medical access as the Jewish population, proposing consanguinity as an important/essential risk factor for EA-TEF.

Barriers to early diagnosis of chronic kidney disease and use of sodium-glucose cotransporter-2 inhibitors for renal protection: A comprehensive review and call to action.

Chronic kidney disease (CKD) affects approximately 13% of people globally, including 20%-48% with type 2 diabetes (T2D), resulting in significant morbidity, mortality, and healthcare costs. There is an urgent need to increase early screening and intervention for CKD. We are experts in diabetology and nephrology in Central Europe and Israel. Herein, we review evidence supporting the use of sodium-glucose cotransporter-2 (SGLT2) inhibitors for kidney protection and discuss barriers to early CKD diagnosis and treatment, including in our respective countries. SGLT2 inhibitors exert cardiorenal protective effects, demonstrated in the renal outcomes trials (EMPA-KIDNEY, DAPA-CKD, CREDENCE) of empagliflozin, dapagliflozin, and canagliflozin in patients with CKD. EMPA-KIDNEY demonstrated cardiorenal efficacy across the broadest renal range, regardless of T2D status. Renoprotective evidence also comes from large real-world studies. International guidelines recommend first-line SGLT2 inhibitors for patients with T2D and estimated glomerular filtration rate (eGFR) ≥20 mL/min/1.73 m2, and that glucagon-like peptide-1 receptor agonists may also be administered if required for additional glucose control. Although these guidelines recommend at least annual eGFR and urine albumin-to-creatinine ratio screening for patients with T2D, observational studies suggest that only half are screened. Diagnosis is hampered by asymptomatic early CKD and under-recognition among patients with T2D and clinicians, including limited knowledge/use of guidelines and resources. Based on our experience and on the literature, we recommend robust screening programmes, potentially with albuminuria self-testing, and SGLT2 inhibitor reimbursement at general practitioner (GP) and specialist levels. High-tech tools (artificial intelligence, smartphone apps, etc.) are providing exciting opportunities to identify high-risk individuals, self-screen, detect abnormalities in images, and assist with prescribing and treatment adherence. Better education is also needed, alongside provision of concise guidelines, enabling GPs to identify who would benefit from early initiation of renoprotective therapy; although, regardless of current renal function, cardiorenal protection is provided by SGLT2 inhibitor therapy.

The childcare director’s role in preventing burnout: a positive-psychological examination of the caregivers’ lived experience

ABSTRACT This study applied a positive-psychological approach to examining childcare directors’ role in maintaining the stability of their staff from the caregivers’ and directors’ points of view. Most of the childcare centers in Israel are characterized by high burnout and turnover of staff members. Nevertheless, some teams stay stable, and turnover is minimal. This study explored the factors using 30 semi-structured interviews with childcare center directors and caregivers regarding their occupational stability. Findings suggested that the sense of belonging to the childcare center was one source of stability. The director acted as a safe haven, maintaining the caregivers’ wellbeing. Other success factors are related mainly to their relations with other staff members, with the director, and with the children, and also to proper management that provides professional training and treats them with respect. The study’s contribution is fourfold. First, it gives voice to a population of women who work under difficult conditions for low pay. Second, it highlights the role of the childcare director in maintaining staff stability. Third, implementing its findings is relevant to creating and improving models of training and supervising early childhood educators. Fourth, studying anti-burnout factors can strengthen teams and provide the children with positive relationships with significant others.

Reviving life that has ceased on October the 7th: an attachment perspective on a virtual reality intervention

Unfortunately, in recent years, wars have forced many civilians to evacuate their homes and move to safe zones. The event of October the seventh that took place in many Kibbutzim near the Gaza strip, exposed families who were on a Jewish holiday, to the murder of family and community members. They had to leave their burned houses and move to hotels and apartment buildings in other parts of Israel. Many people, also from the Northen parts of the country, are still in new safe zones, and have huge difficulties in returning to their houses (and not only because of objective security reasons). In this “perspective” article we propose a Virtual Reality (VR) application, which is based on past and current research in the fields of attachment theory and traumatic grief. We propose that in addition to the use of exposure therapy, a VR simulation which will activate the attachment system, can reorganize the evacuees’ figure and place attachment representations. We suggest that such a simulation will revive the evacuees’ sense of safe-haven and secure base and enable them to return to their home place, or to adjust to a new place, thereby leading to optimal adjustment. We start with a presentation of the theory of attachment, place attachment, attachment and loss and the two-track model of bereavement. Then, we describe the design of our VR intervention that aims to address this challenge from the attachment theory perspective with the evacuees. Finally, we discuss the challenges that need to be dealt with to implement the VR interventions through resilience centers in Israel.

Medical perspectives on Israeli children after their release from captivity - A retrospective study.

Following the Hamas terror attack on Israeli towns on October 2023, 250 individuals were taken into captivity. On November-December 2023, during the cease-fire deal, 26 women and children were released. This study is the first to describe the physical and behavioural findings in children and their mothers in the immediate phase of returning home from captivity. This is a retrospective study describing the clinical characteristics of the returnees after 49-53 days in captivity. Patients were admitted to a designated unit in the Schnieder Children's Medical Center of Israel on November-December 2023. The hospitalisation duration was 1-9 days. All patients were evaluated according to a detailed protocol and were treated respectively. Patient population included 19 children (ranged 2-18 years old) and 7 women (ranged 34-78 years old). The most common clinical findings upon return included significant weight loss, psychological trauma, complications of poor hygiene and complications of recent shrapnel injuries. Microbiology tests were positive for multiple gastrointestinal pathogens. Serologic screening tests were positive for various infectious diseases. Clinical findings in this time period were diverse and required the attention of a multidisciplinary team. Long term clinical and psychological effects are yet to be known.

Anterior Chamber Intraocular Lens Implantation Versus Four-Flanged Scleral Fixation Technique for Patients With Loss of Capsular Support During Routine Cataract Surgery.

To compare the outcomes of anterior chamber intraocular lens (AC-IOL) implantation versus the four-flanged scleral fixation technique in eyes with loss of capsular support during routine cataract surgery. This was a retrospective cohort study of all patients in whom an IOL was implanted either during or after short-term aphakia due to loss of capsular and sulcus support in a routine cataract surgery with at least 6 months of follow-up time between 2015 and 2023 in a tertiary medical center in Israel. Two different IOL implantation techniques were compared: the implantation of an angle-supported ACIOL and four-flanged scleral fixation. Main outcome measures included postoperative complications such as pseudophakic bullous keratopathy, loss of intraocular pressure control and glaucoma, IOL subluxation, and retinal detachment. Sixty-five eyes of 65 patients were included in the study, 33 eyes in the AC-IOL group and 32 eyes in the flange group. Follow-up time was 29.92 ± 20.02 months in the AC-IOL group and 20.17 ± 15.56 months in the flange group (P = .087). Pseudophakic bullous keratopathy was observed in 10 (30.3%) patients in the AC-IOL group and in 1 (3.1%) patient in the flange group (P = .04). This association remained significant using survival analysis (P = .006). In 4 (12.1%) patients in the AC-IOL group, a glaucoma filtering procedure was performed to control the intraocular pressure compared with none in the flange group (P = .042). In the setting of loss of capsular support during routine cataract surgery, four-flanged scleral fixation showed an overall lower rate of complications and significantly reduced rate of subsequent surgical interventions.

Computer-aided diagnosis of eyelid skin tumors using machine learning

ObjectiveTo develop an automated, new framework based on machine learning to diagnose malignant eyelid skin tumors. MethodsThis study used eyelid lesion images from Sheba Medical Center, a large tertiary center in Israel. Before model training, we pretrained our models on the International Skin Imaging Collaboration (ISIC) 2019 dataset consisting of 25,332 images. The proprietary eyelid data set was then used for fine-tuning. The data set contained multiple images per patient, aiming to classify malignant lesions in comparison to benign counterparts. ResultsThe analyzed data set consisted of images representing both benign and malignant eyelid lesions. For the benign category, a total of 373 images were sourced. By comparison, for the malignant category, 186 images were sourced. For the final model, at sensitivity of 93.8% (95% CI 80.0–100.0%), the model has a corresponding specificity of 73.7% (95% CI 60.0–87.1%). To further understand the decision-making process of our model, we employed heatmap visualization techniques, specifically gradient-weighted Class Activation Mapping. DiscussionThis study introduces a dependable model-aided diagnostic technology for assessing eyelid skin lesions. The model demonstrated accuracy comparable to human evaluation, effectively determining whether a lesion raises a high suspicion of malignancy or is benign. Such a model has the potential to alleviate the burden on the health care system, particularly benefiting rural areas, and enhancing the efficiency of clinicians and overall health care.

Geographic Inequity in Physical Medicine and Rehabilitation Services: An Administrative Case Report of Successful Advocacy for Change.

Following an injury or disease, physical medicine and rehabilitation (PM&R) services are often necessary to help patients recover function, activity, and community participation. Ten years ago, there was a significant gap between PM&R services in central Israel and those in the rural north of the country in terms of quality, quantity, and layout. The purpose of this administrative case report is to outline the gap in PM&R services between regions in Israel, as portrayed above; to describe a decade of civil action; and to describe civil action administrative approaches and actions that contributed to changes in the PM&R services now available in northern Israel. A decade of civil action to promote PM&R services is reviewed, illustrating the main administrative steps, including initiating and organizing meetings with key partners, lobbying, testifying in front of parliament and government committees, garnering media attention to promote public awareness, and filing a case with the Supreme Court of Israel. The encountered challenges and the subsequent actions are also described. Awareness of the significance of PM&R services and of the inadequacy of such services in the northern part of Israel rose due to our actions, with practical field results, including an 180-bed government rehabilitation center that plans to open during 2024, and 5 daycare rehabilitation clinics and a private inpatient center that opened between 2020 and 2023. Data-driven research will aid in understanding the current gaps and tracking improvements with the opening of the new rehabilitation facility. When inequality is brought to light, and legislation for equality exists, civil action can promote change to reduce these gaps. Others can follow the steps taken in this administrative case report to achieve success in struggles aiming to correct comparative inequality.

Breaking bad news: Comparing the perception of the role, barriers and experiences of neonatal intensive care and well-baby nursery nurses.

Nurses accompany patients throughout the breaking bad news process. The aim of the research was to compare neonatal intensive care unit (NICU) nurses and well-baby nursery (WBN) nurses on their role, barriers and experiences in breaking bad news to parents/relatives during hospitalization. A cross-sectional comparative study. Two medical centres in Israel were employed. A 39-item questionnaire was distributed with 140 nurses participating in the study. STROBE Checklist was used. A total of 140 nurses participated in this study. There was no significant overall difference (p ≤ .45) between NICU and WBN nurses in their perception of their role in breaking bad news. Differences were found in barriers to the role which included a lack of information, lack of time and communication issues. No differences were found in the nurses' experiences in breaking bad news. NICU and WBN nurses reported that they received no support (n = 40, 58.8%; n = 45, 64.3%, respectively). No breaking bad news specialty team existed in either unit (NICU: n = 64, 91.4%; n = 60, 87.0%). Nurses in the WBN and NICU are involved in breaking bad news. The role of the nurse has not been fully acknowledged making it difficult to perform. Nurses' experiences in breaking bad news were varied. Nurses facing challenges should be provided guidance and support. This needs to be implemented. The role played by nurses in breaking bad news has not been fully acknowledged making it difficult to perform. Nurses need to receive formal training and support in order to improve this practice.

Death at the water hole: Opportunistic hunting and scavenging events in the upper sequence of Middle Paleolithic Nesher Ramla, Israel

Distinguishing between selective and opportunistic hunting is a major challenge in Paleolithic archaeology, requiring the comparison of the human hunting record to the usually unknown natural prey abundance. Open-air hunting camps are ubiquitous in the Eurasian Middle Paleolithic (MP) record, alongside cave sites, and are often dominated by large-bodied species. In the Levant, MP faunal records differ between caves and open-air sites: Caves are dominated by mountain gazelle and fallow deer, while open-air sites are more aurochs-dominated. This discrepancy can be explained by transport patterns, but whether the abundance of aurochs in open-air sites is due to deliberate targeting or natural abundance in the landscape is unclear. The Nesher Ramla open-air site is a natural sinkhole in central Israel with an 8-m-deep MP sequence. Detailed zooarchaeological, dental wear, and isotope analyses of the upper sequence fauna found a highly diverse assemblage dominated by medium-sized ungulates in the uppermost phases (Units I and IIa). Results concerning ungulate dietary niches and isotopic signatures demonstrate that animals from different biomes and topographies congregated at the site. Evidence of human butchery is infrequent and fewer than carnivore modifications. Several articulated vertebral columns attest to in situ preservation. Our results demonstrate that the Nesher Ramla's uppermost sequence formed primarily under natural conditions, suggesting that it was a site of opportunistic hunting by humans and carnivores, probably targeting ungulates that came to the sinkhole to drink. Therefore, we consider this assemblage representative of the site's “natural” environment and use it as a benchmark for comparing assemblages and hunting strategies. Thus, we observe a clear difference between our case study and those recovered from the site's lower layers (Unit IIB and below) and other open-air sites. For the first time, we can show that the abundance of large bovines in MP open-air sites is not necessarily due to their abundance in the environment but to deliberate human planning and selective hunting.

Effect of Added Inhaled Corticosteroids to Systemic Steroids on COPD Exacerbation Outcomes.

COPD exacerbations are a major cause of morbidity and mortality. Although inhaled corticosteroids (ICS) have a role as long-term treatment, their efficacy in exacerbations, particularly as an adjunct to systemic steroids, remains unclear. In this retrospective observational study, we analyzed data from 870 subjects admitted with COPD exacerbations to a tertiary medical center in Israel from January 2018-January 2023. We investigated the impact of adding ICS to standard systemic steroid treatment on hospital length of stay, intubation rates, and 30-d mortality using propensity score matching to account for confounders. The cohort, after matching, included 354 subjects treated with systemic steroids and ICS and 121 treated with systemic steroids alone. All characteristics were similar between the groups. Our analysis showed no differences in 30-d mortality (7.1% vs 5.8%, P = .63) or secondary outcomes (intubation, hospital length of stay, and readmission rates) between the groups. Subgroup analyses based on different eosinophil levels did not alter these findings. In multivariate analysis among the general cohort, eosinophil count < 150 cells/μL (adjusted odds ratio 0.45 [95% CI 0.21-0.87], P = .02) and high Charlson score (adjusted odds ratio 1.19 [95% CI 1.02-1.37], P = .02) were independent predictors for 30-d mortality. Despite the known benefits of ICS in managing chronic COPD, we did not find an added value of ICS to systemic steroids in exacerbations. These results underscore the necessity for individualized treatment strategies and further research into the role of ICS in COPD exacerbations.

The natural history of dihydrolipoamide dehydrogenase deficiency in Israel.

Dihydrolipoamide dehydrogenase (DLD) deficiency is an ultra-rare autosomal-recessive inborn error of metabolism, affecting no less than five mitochondrial multienzyme complexes. With approximately 30 patients reported to date, DLD deficiency was associated with three major clinical presentations: an early-onset encephalopathic phenotype with metabolic acidosis, a predominantly hepatic presentation with liver failure, and a rare myopathic phenotype. To elucidate the demographic, phenotypic, and molecular characteristics of patients with DLD deficiency within the Israeli population, data were collected from metabolic disease specialists in four large tertiary medical centers in the center and south of Israel. Pediatric and adult patients with biallelic variants in DLD were included in the study. A total of 53 patients of 35 families were included in the cohort. Age at presentation ranged between birth and 10 years. Wide phenotypic variability was observed, from asymptomatic individuals in their sixth decade of life, to severe, neonatal-onset disease with devastating neurological sequelae. Six DLD variants were noted, the most common of which was the c.685G>T (p.G229C) variant in homozygous form (24/53 patients, 45.3%; 13/35 families), observed mostly among patients of Ashkenazi-Jewish descent, followed by the homozygous c.1436A>T (p.D479V) variant, found in 20 patients of Bedouin descent (37.7%; 16/35 families). Overall, patients did not necessarily present as one of the previously described distinct clinical phenotypes. DLD deficiency is a panethnic disorder, with significant phenotypic variability, and comprises a continuum, rather than three distinct clinical presentations.

Cardiac surgery during wartime in Israel

BackgroundThe war that began on October 7th, 2023, has impacted all major tertiary medical centers in Israel. In the largest cardiac surgery department in Israel there has been a surprising increase in the number of open-heart procedures, despite having approximately 50% of surgeons recruited to military service. The purpose of this study is to characterize this increase in the number of operations performed during wartime and assess whether the national crisis has affected patient outcomes.MethodsThe study was based on a prospectively collected registry of 275 patients who underwent cardiac surgery or extracorporeal membrane oxygenation (ECMO) during the first two months of war, October 7th 2023 – December 7th 2023, as well as patients that underwent cardiac surgery during the same period of time in 2022 (October 7th, 2022 – December 7th, 2022).Results120 patients (43.6%) were operated on in 2022, and 155 (56.4%) during wartime in 2023. This signifies a 33.0% increase in open-heart procedures (109 in 2022 vs. 145 in 2023, p-value 0.26). There were no significant differences in the baseline characteristics of patients when comparing the 2022 patients to those in 2023. No significant differences between the two groups were found with regards to intraoperative characteristics or the type of surgery. However, compared to 2022, there was a 233% increase in the number of transplantations in the 2023 cohort (p-value 0.24). Patient outcomes during wartime were similar to those of 2022, including postoperative complications, length of stay, and mortality.ConclusionsPatients who underwent cardiac surgery during wartime presented with comparable outcomes when compared to those of last year despite the increase in cardiac surgery workload. There was an increase in the number of transplants this year, attributed to the unfortunate increase in organ donors.

Physical restraint and associated agitation.

Physical restraint of patients in intensive care units (ICUs) has an estimated prevalence of 50%. Many medical centres do not have specific protocols for physical restraint, and the decision of whether to physically restrain a patient is up to the nursing staff. Disadvantages of physical restraint include injuries, exacerbation of agitation and an increased risk of developing post-traumatic stress disorder (PTSD). To report prevalence and outcomes in terms of morbidity and mortality of physical restraint in general ICU patients in an 800-bed secondary medical centre. This retrospective study included 647 patients admitted to a general ICU in an 800-bed secondary medical centre in Kfar Saba, Israel, between January and December 2020. Data included demographics, medical history, length of stay, need for mechanical ventilation, number of ventilation days, 28-day mortality, reason for admission, agitation rate assessed by Richmond Agitation and Sedation Scale (RASS) score, need for physical restraint and need for anti-psychotics. Among the patients, 40% (256 of 647) required physical restraint. Older adult patients had a greater likelihood of being physically restrained along with those admitted because of sepsis or acute respiratory failure. Among the study sample, 11% (71 of 647) required anti-psychotics. Patients who were restrained had longer duration of ventilation (5.9 ± 8.2 vs. 0.36 ± 1.4 days; p < .001) and higher 28-day mortality (0.26 ± 0.45 vs. 0.07 ± 0.25, Z = 6.86, p < .001). There was no difference in medical history, except for chronic drug abuse, which was more frequent in the restraint group (18 [6.9%] vs. 11 [2.8%], respectively; p = .019), as well as the use of anti-psychotic medications (24 [9.3%] vs. 19 [4.8%], respectively; p = .034) and anti-depressants (55 [21.2%] vs. 59 [14.8%], respectively; p = .042). The restraint group had higher disease severity scores, as reflected in requirements for vasopressor support (174 [67.2%] vs. 69 [17.3%], respectively; p < .001) and need for dialysis (39 [15.1%] vs. 19 [4.8%], respectively; p < .001); higher frequency of in-hospital anti-psychotic treatment (60 [23.2%] vs. 11 [2.8%], respectively; p < .001); a greater tendency for agitation events and more severe agitation scores (episodes of RASS above zero [1.7 ± 4.0 vs. 0.04 ± 0.27, respectively; p < .001] and maximum RASS score [0.19 ± 1.6 vs. 0.01 ± 0.54, respectively; p < .001]). Overall, advanced age, number of ventilation days and need for dialysis were associated with increased 28-day mortality. In the restraint group, advanced age, chronic use of diuretics and the use of dialysis during ICU admission were associated with increased mortality risk. Restrained patients tended to have higher morbidity and mortality during ICU and hospital stays, as well as a greater tendency for agitation events and more severe agitation scores, with an increased need for in-hospital anti-psychotic treatment. These findings regarding patient characteristics might be used to formulate treatment plans to reduce the rate of physical restraint in the ICU. Because restrained ICU patients tend to have higher morbidity and mortality, treatment plans should be formulated to reduce the rate of physical restraint in the ICU. NCT04771793.

Echocardiographic Predictors of Improvement of Left Ventricular Ejection Fraction below 35% in Patients with ST-Segment Elevation Myocardial Infarction.

Introduction: An ST-elevation myocardial infarction (STEMI) is a clinical syndrome defined by symptoms of myocardial ischemia, persistent electrocardiographic ST-segment elevation and subsequent release of biomarkers suggestive of myocardial necrosis. In clinical practice, echocardiography has become essential in evaluating patients after acute myocardial infarction. We aimed to assess clinical and echocardiographic parameters that may affect LV function recovery in patients after STEMI. Methods: This study is a retrospective observational study from a tertiary referral center in Israel. We collected patients that were admitted with STEMI and a left ventricular ejection fraction (LVEF) below 35% on preliminary echocardiography at the index hospitalization and compared the findings to a follow-up study performed within 1-6 months after that event, in order to see if there are predictors of LVEF change > 10% within 90 days following STEMI. Results: This study included 101 patients that were admitted between 2016 and 2021. Within a median follow-up of 9.7 weeks (IQR 5.9-17.1), 27 (25.2%) patients had improved their LVEF, and 74 (69.2%) had no change or further reduced LVEF. Compared to patients without LVEF improvement, those with improved LVEF were more likely to be female (29.6% vs. 9.5%, p = 0.01), less likely to suffer from hypertension (33.3% vs. 56.8%, p = 0.04) and had marginally higher rates of thrombolysis treatment (14.1% vs. 4.1%, p = 0.06). Conclusions: in the population of STEMI patients with residual LVEF < 35%, approximately a quarter will improve at least 10% in their follow-up LVEF, and there were no clear echocardiographic predictors for this improvement.

Vaginal Progesterone for Pregnancy Prolongation After Arrested Preterm Labor

Women with arrested preterm labor (APTL) are at very high risk for spontaneous preterm delivery (SPTD), the leading cause of neonatal mortality and morbidity. To date, no maintenance therapy has been found to be effective for pregnancy prolongation. A few clinical trials with considerable methodological limitations have demonstrated some efficacy for 400 mg vaginal micronized progesterone (VMP) in women with APTL. To investigate the effectiveness of daily 400 mg VMP for the prolongation of pregnancy after APTL. This randomized clinical trial was conducted between December 19, 2018, and February 27, 2023, in 3 university-affiliated medical centers in Israel. Participants included women with singleton and twin pregnancies after APTL following tocolysis at 24 weeks 0 days to 34 weeks 0 days' gestation. Women with a history of preterm delivery or asymptomatic cervical shortening in the current pregnancy were excluded. Participants were randomly allocated to receive VMP 200 mg twice a day or no treatment until 36 weeks 6 days' gestation. The primary end points were mean number of days from study enrollment to delivery and the rate of SPTD prior to 37 weeks' gestation. A total of 129 participants were enrolled (65 in the VMP group and 64 in the no-treatment group). Mean (SD) age was 27.6 (5.1) years. Between the VMP and no-treatment groups, there was no difference in pregnancy prolongation (mean [SD], 40.0 [17.8] vs 37.4 [20.3] days; P = .44) and the rate of SPTD (16 [25%] vs 19 [30%]; relative risk, 0.8; 95% CI, 0.5-1.5; P = .52). In twin pregnancies, including 12 and 15 pairs in the VMP and no-treatment groups, respectively, VMP prolonged pregnancy (mean [SD], 43.7 [18.1] vs 26.1 [15.2] days; P = .02), postponed the delivery week (36.5 [1.4] vs 34.7 [2.2] weeks; P = .01), shortened the length of stay in the neonatal intensive care unit (4.9 [10.6] vs 13.2 [18.5] days; P = .03) and overall hospital stay (8.3 [9.6] vs 15.1 [17.2] days; P = .03), and was associated with a higher birth weight (2444 [528] vs 2018 [430] g; P = .01). These findings show that VMP given in a dosage of 200 mg twice a day following APTL is not an effective treatment to prolong pregnancy or prevent SPTD. However, VMP demonstrated beneficial effects in twin pregnancies, warranting further investigation. ClinicalTrials.gov Identifier: NCT02430233.
