Background and Aim: Drug sustainability (DS) is a surrogate marker for treatment efficacy. We aimed to compare the DS of two main biologics used to treat moderate-to-severe ulcerative colitis (UC), infliximab (IFX) and vedolizumab (VDZ), in a real-world setting. Methods: We conducted a retrospective cohort study at a tertiary medical center in Israel. We included patients treated between 1 December 2017 and 1 May 2021, who were followed for up to 300 weeks. DS was defined as corticosteroid-, surgical-, and hospitalization-free treatment. Results: 217 patients with UC were included. VDZ had a significantly longer median DS of 265.6 weeks compared to IFX's 106.5 weeks (p = 0.001) in treatment-naïve patients, even when adjusting for disease severity (HR 0.55 95 CI 0.3–0.98, p = 0.042). In treatment-experienced patients, DS was comparable between IFX and VDZ (p = 0.593). Conclusions: VDZ showed significantly longer DS in treatment-naïve patients with UC compared to IFX, also when adjusted for disease severity. There was no difference in DS between VDZ and IFX in treatment-experienced patients and patients switching from one drug to another. VDZ may be a suitable first-line treatment for biologic-naïve patients with moderate-to-severe UC. [ABSTRACT FROM AUTHOR]

Aram, D. and Biron, S.
- Abstract
This study compared two interventions: one focusing on language and storybook reading and the other on alphabetic skills and writing. Seventy-one preschoolers aged 3-5 from a low SES township in central Israel (35 in the reading program and 36 in the writing program) participated in evaluation of the interventions. Twenty-four untreated preschoolers served as a control group. The children were tested twice, at the beginning and at the end of the school year, in: phonological awareness, word writing, letter knowledge, orthographic awareness, listening comprehension, receptive vocabulary, and general knowledge. Both programs involved games and creative activities. The writing program encouraged letter knowledge, phonological awareness, and functional writing activities. The reading program utilized 11 children's books for focusing on language and exploring major concepts raised by these books. Results indicated that children in the two literacy programs progressed significantly more than the control group on phonological awareness and orthographic awareness. However, the joint writing group significantly outperformed both the joint reading group and the control group on phonological awareness, word writing, orthographic awareness, and letter knowledge. We also found that children as young as 3-4 years gained from literacy programs as much as did older children, aged 4-5, on all the measures assessed in our program.

Purpose: Much of what we know about work from home (WFH) is based on data collected in routine times, where WFH is applied on a partial and voluntary basis. This study leverages the conditions of mandatory WFH imposed by COVID-19 lockdowns to shed new light on factors that relate to well-being and performance among employees who WFH. Specifically, the authors explore how boundary control and push–pull factors (constraints and benefits that employees associate with WFH) interact to shape employees' exhaustion and goal setting/prioritization. Design/methodology/approach: Surveys were administered in Israel and in the USA to 577 employees in "teleworkable" roles who were mandated to WFH shortly after the COVID-19 outbreak (March–April 2020). Findings: (1) Boundary control is negatively related to exhaustion and positively related to goal setting/prioritization. (2) These associations are weakened by perceptions of high WFH constraints (push factors). (3) WFH benefits (pull factors) attenuate the moderating effect of WFH constraints. Practical implications: Organizations may benefit from identifying and boosting the saliency of WFH benefits, while considering and remedying WFH constraints. Originality/value: The authors contribute theoretically by integrating push–pull factors into the discussion about WFH and boundary management. We also make a contextual contribution by drilling down into the specificities of nonvoluntary WFH. The expected upward trends in nonvoluntary WFH rates underscore the need to understand factors that improve outcomes among individuals who lack agency in the decision to WFH. [ABSTRACT FROM AUTHOR]

POSTPARTUM depression ,COVID-19 ,LONGITUDINAL method ,SOCIAL support ,REGRESSION analysis - Abstract
COVID-19 impacted the childbirth experience and increased the rates of postpartum depression (PPD). We assessed the longitudinal effects of the pandemic on the rates of PPD and evaluated the PPD causes and symptoms among women who delivered during the first COVID-19 quarantine in Israel. The participants completed online questionnaires 3 (T1) and 6 months (T2) following delivery. We used the 'COVID-19 exposure' questionnaire, while PPD symptoms, situational anxiety, and social support were evaluated with the EPDS, STAI, and MSPSS questionnaires. The mean EPDS scores increased between T1 and T2 (6.31 ± 5.6 vs. 6.92 ± 5.9, mean difference −0.64 ± 4.59 (95% CI (−1.21)–(−0.06)); t (244) = −2.17, p = 0.031), and the STAI scores decreased (45.35 ± 16.4 vs. 41.47 ± 14.0, t(234) = 4.39, p = 0.000). Despite the exposure to an increased number of COVID-19 events (3.63 ± 1.8 vs. (6.34 ± 2.3)), the impact of exposure decreased between T1 and T2 (8.91 ± 4.6 vs. 7.47 ± 4.1), p < 0.001). In the MSPSS, significant differences were noted on the family scale between the T1 (6.10 ± 1.3) and T2 (5.91 ± 1.4) scores; t (216) = 2.68, p = 0.0008. A regression analysis showed three statistically significant variables that correlated with increased EPDS scores: the MSPSS family subscale (F (1212.00) = 4.308, p = 0.039), the STAI scores (F (1212.00) = 31.988, p = 0.000), and the impact of exposure to COVID-19 (F (1212.00) = 5.038, p = 0.026). The rates of PPD increased for women who delivered during the first COVID-19 lockdown. Further research is warranted to help reduce PPD among these women. [ABSTRACT FROM AUTHOR]

Background and Aims: Skin eruptions are prevalent among patients with inflammatory bowel diseases (IBD), often associated with therapies and frequently leading to dermatological consults and treatment interruptions. We aimed to assess the impact of joint shared decision-making in a multidisciplinary (MDT) IBD-DERMA clinic. Methods: This retrospective cohort study assessed a consecutive group of patients with IBD who were referred for consultation in an MDT clinic at a tertiary referral center in Israel. Results: Over 1 year, 118 patients were evaluated in the MDT-IBD-DERMA clinic: 68 (57.6%) males; age – 35.2 ± 13.5 years, disease duration – 7.1 (interquartile range: 3.7–13.9) years; Crohn's disease – 94/118 (79.6%). Skin eruption induced by an anti–tumor necrosis factor (TNF) were the most common diagnoses [46/118 (39%)], including psoriasiform dermatitis (PD) – 31/46 (67.4%) and inflammatory alopecia (IA) – 15/46 (32.6%). Of these, 18 patients (39.1%) continued the anti-TNF agent concomitantly with a topical or systemic anti-inflammatory agent to control the eruption. The remaining 28 patients (60.9%) discontinued the anti-TNF, of whom 16/28 (57.1%) switched to ustekinumab. These strategies effectively treated the majority [38/46 (82.6%)] of patients. Continuation of the anti-TNF was possible in a significantly higher proportion of patients with PD: 12/31 (38.7%) than only one in the IA group, p = 0.035. There was a higher switch to ustekinumab among the IA 7/15 (46.6%) compared with the PD 7/31 (22.6%) group, P =.09. Following IBD-DERMA advised intervention, IBD deteriorated in 9/4 6(19.5%) patients, 5/9 on ustekinumab (PD versus IA, P = NS). Conclusion: Shared decision-making in an integrated IBD-DERMA clinic allowed successful control of skin eruptions while preserving control of the underlying IBD in more than 80% of cases. Patients with IA profited from a switch to ustekinumab. [ABSTRACT FROM AUTHOR]

Key Message: Among SARS-CoV-2-infected mothers, vaginal delivery rates were high and associated with favorable outcomes with no cases of neonatal COVID-19.Purpose: To investigate the mode of delivery and its impact on immediate neonatal outcome in SARS-CoV-2-infected women.Methods: A prospective study following pregnant women diagnosed with COVID-19 who delivered between March 15th and July 4th in seven university affiliated hospitals in Israel.Results: A total of 52 women with a confirmed diagnosis of COVID-19 delivered in the participating centers during the study period. The median gestational age at the time of delivery was 38 weeks, with 16 (30.8%) cases complicated by spontaneous preterm birth. Forty-three women (82.7%) underwent a trial of labor. The remaining 9 women underwent pre-labor cesarean delivery mostly due to obstetric indications, whereas one woman with a critical COVID-19 course underwent urgent cesarean delivery due to maternal deterioration. Among those who underwent a trial of labor (n = 43), 39 (90.7%) delivered vaginally, whereas 4 (9.3%) cases resulted in cesarean delivery. Neonatal RT-PCR nasopharyngeal swabs tested negative in all cases, and none of the infants developed pneumonia. No maternal and neonatal deaths were encountered.Conclusions: In this prospective study among SARS-CoV-2-infected mothers, vaginal delivery rates were high and associated with favorable outcomes with no cases of neonatal COVID-19. Our findings underscore that delivery management among SARS-CoV-2-infected mothers should be based on obstetric indications and may potentially reduce the high rates of cesarean delivery previously reported in this setting.

Purpose: To present a series of cases in which the 4-flanged technique was used in the management of in-the-bag intraocular lens (IOL) subluxation. Setting: Shamir Medical Center, Israel. Design: Retrospective cohort analysis. Methods: Included were consecutive cases with secondary IOL subluxation that underwent scleral fixation with the 4-flanged technique using 6-0 polypropylene and low temperature cautery. Surgeries were performed during September 2019 to April 2020. Postoperative IOL angle tilt was evaluated using high-resolution ocular coherence tomography. Results: Eleven eyes of 11 patients were included. The mean age was 82.7 +/- 5.5 years, and 60% were men. Pseudoexfoliation was noted in 82% of patients, and only 1 case was related to trauma. The mean corrected distance visual acuity (CDVA) postoperatively was within 1 line of the original presubluxation CDVA (0.55 +/- 0.41 vs 0.54 +/- 0.6 logMAR, P =.965). The mean postoperative IOL tilt was 5.78 +/- 3.85 degrees. Surgery duration decreased from 70 +/- 14 minutes to 39 +/- 15 minutes (first to last operations). No intraoperative complications were reported. Postoperatively, transient intraocular pressure elevation, which resolved at 1 week, was recorded in 45% of cases. Cystoid macular edema, which resolved within a few months under topical treatment, was seen in 2 patients. Conclusions: Among a cohort of patients with secondary in-the-bag IOL subluxation, the 4-flanged technique was safe and resulted in satisfactory visual outcomes and a stable IOL position, with a short learning curve.

Background. New recommendations regarding the use of personal protective equipment (PPE) during delivery have changed the maternal birth experience. In this study, we investigated the mental perceived impact of PPE use during delivery on the development of maternal postpartum depression (PPD) and post-traumatic stress symptoms (PTSS). Methods. This was a multicenter, retrospective cohort study concerning women who delivered during the COVID-19 pandemic first lockdown period in Israel. Postpartum women were approached and asked to complete a comprehensive online questionnaire. Impact of PPE was graded on a scale of 1-5, and Impact of PPE =4 was considered high. PPD and PTSS were assessed using the EPDS and City BiTS questionnaires. Results. Of 421 parturients, 36 (9%) reported high Impact of PPE. Parturients with high Impact of PPE had significantly higher PPD and PTSS scores)EPDS 8.4 ± 5.8 vs. 5.7 ± 5.3; City BiTS 9.2 ± 10.3 vs. 5.8 ± 7.8, p < 0.05 for both). Following adjustment for socio-demographic and delivery confounders and fear of COVID-19 (using Fear of COVID19 scale), Impact of PPE remained positively correlated with PPD symptoms (ß = 0.103, 95% confidence intervals [CI] 0.029-1.006, p = 0.038). Conclusion. When examining the risk factors for developing postpartum PTSS--experiences during labor and PPE were found to be significant variables. As the use of PPE is crucial in this era of COVID-19 pandemic in order to protect both parturients and caregivers, creative measures should be taken in order to overcome the communication gap it poses.

Objective: This study examined the effects of early-onset preeclampsia (EOPE) and late-onset preeclampsia (LOPE) on short-term maternal and neonatal morbidity, as well as risk factors associated with early-onset and late-onset diseases.Method: This retrospective, cohort study included pregnant women who had been diagnosed with PE during pregnancy. Electronic medical records were reviewed for demographics and medical history, laboratory tests, and delivery data. The women were grouped according to EOPE (<34 weeks) and LOPE (≥34 weeks). Power analysis revealed that a sample size of 35 was sufficient for each PE group, under the assumptions of type I error (two-sided) of 5% and at least 80% power to detect a 30% difference in composite outcomes between EOPE and LOPE.Results: Among 101 patients, 35 (34.7%) had EOPE and 66 (65.3%) developed LOPE. Alpha fetoprotein (AFP) and unconjugated estriol (UE3) were higher in the early-onset group (p = .015 and p= .002, respectively) and might be predictors of EOPE. There was a positive correlation between gestational age at PE diagnosis and gestational age at delivery. Patients with EOPE delivered earlier than patients with LOPE did (p<.0001).Conclusions: Patients who developed EOPE had higher of AFP and UE3 values at their second trimester biochemical screening. These parameters might be predictors of EOPE. We found a positive correlation between early gestational age at PE diagnosis and preterm delivery. [ABSTRACT FROM AUTHOR]

Objective: To compare the predictive value of preterm birth (PTB) by transvaginal sonographic cervical length (CL) measurement to digital examination of the cervix (Bishop score - BS), in patients with premature contractions (PC) and intact membranes. Design: A retrospective case-control study. Setting: Meir Medical Center, Kfar Saba, Israel. Population: Women at 24-34 weeks of gestation who were hospitalized with PC and intact membranes. Methods: All patients underwent CL and BS measurements upon admission. Power analysis revealed that 375 patients were needed to show a significant difference between the two methods for predicting PTB. Each one served as her own control. Main outcome measures: PTB < 37 and < 34 weeks. Results: Receiver-operator characteristic curve (ROC) and logistic regression analyses indicated a correlation between both shortened CL and increased BS to PTB (P < 0.001). Neither test offered an advantage in predicting PTB. Areas under the curve for BS and CL ROC were similar for PTB before 37 weeks gestation (0.611 vs. 0.640, P = 0.28). For nulliparous women, CL predicted PTB better that BS (0.642 vs. 0.724, P = 0.03). For singleton and multiple pregnancy pregnancies, BS and CL did not differ significantly in predicting PTB (P = 0.9, P = 0.2, respectively). For nulliparous with multiple pregnancy, the BS and CL ROC curves differ nearly significantly (0.554 vs. 0.709, P = 0.07), with better predictive ability for CL. Conclusions: CL and BS have similar value in predicting PTB in patients with PC. For nulliparous women, CL is superior over the BS. [ABSTRACT FROM AUTHOR]

Objective: Motor vehicle accidents (MVAs) are a major incidental cause of pregnancy-associated maternal deaths in the US. The goal of this research was to evaluate the incidence, risks, and fetal and maternal outcomes of pregnant women involved in MVAs. In addition, we examined the relationship between the injury severity score (ISS) and car seat location in pregnant and non-pregnant women. Methods: This involved a retrospective cohort study of female patients who were involved in MVAs and hospitalized between the years 2006 and 2013. Data were collected from the Israeli National Trauma Registry. Severity and outcomes of pregnant and non-pregnant women with blunt trauma were compared. Results: In this study, 3794 pregnant and 3441 non-pregnant patients aged 18-40 years were analyzed. The majority of pregnant patients were drivers (n=2515, 67%) as opposed to passengers (n=1279, 33%). Pregnant patients had lower ISS than non-pregnant patients (P<0.001). Out of these pregnant patients, 38 (1%) had adverse maternal-fetal pregnancy outcomes, including (1) placental abruption 0.1% and (2) miscarriage (0.2%). One pregnant patient died (0.03%) compared with 32 (0.93%) of the non-pregnant patients (P<0.0001). A significant negative correlation between gestational age and spontaneous abortion was found (P<0.009). Conclusions: The severity of injury and the mortality rate of pregnant patients involved in MVAs are significantly lower compared with non-pregnant patients. Pregnant drivers had a significantly lower severity of trauma compared with pregnant passengers. [ABSTRACT FROM AUTHOR]

Objectives: Infants with intrauterine growth restriction (IUGR) have increased morbidity and mortality. The decision whether to induce labor at term or to expectantly manage these pregnancies is controversial. The aim of this study was to assess the outcomes of these two management strategies in term pregnancies. Study design: This retrospective cohort study compared neonatal and maternal morbidity and mortality of IUGR fetuses (estimated fetal weight below the 10
th percentile) between induced and spontaneous labors. Results: Records of 669 IUGR newborns were reviewed; 499 were delivered through spontaneous labor and 170 were delivered through induced labor. Epidemiology and early perinatal outcomes between the two groups were similar. The cesarean section rate was significantly higher (P<0.005) in the induced group. Conclusions: Expectant management for term IUGR pregnancies seems to be safe, with lower rates of cesarean deliveries. A large, prospective, randomized controlled trial with long-term neonatal follow-up is indicated. [ABSTRACT FROM AUTHOR]- Published

We used a national sample of 100 Israeli enterprises to examine the prevalence and distribution of employee substance-related workplace problems, as well as the prevalence and distribution of alternative programs/policies aimed at addressing such problems among Israeli workplaces. Although 29% of the responding firms reported having handled one or more cases involving employee workplace substance use or impairment, across these firms, only 53 actual cases were reported. Given an average enterprise size of 325 employees, this suggests a workforce prevalence rate for such problems of O.16%. Only 10% of the enterprises studied offered any type of substance-related employee assistance, and only 12% included a specific reference to substance use in their discipline policy. The social policy and workplace implications of these findings are discussed. [ABSTRACT FROM AUTHOR]

This article is a response to comments made about a study on risk factors for retained placenta in first pregnancies. The authors aimed to help doctors identify women at risk for this condition in order to develop prevention and response strategies during delivery. However, the study had limitations, such as missing data on potential risk factors and postpartum complications. The study focused on a specific population of primigravidas in Israel, so its generalizability is limited and should be further evaluated in other populations. The authors hope that future research will explore the potential risk factors identified in their study. [Extracted from the article]

BACKGROUNDThe significant risks posed to mothers and fetuses by COVID-19 in pregnancy have sparked a worldwide debate surrounding the pros and cons of antenatal SARS-CoV-2 inoculation, as we lack sufficient evidence regarding vaccine effectiveness in pregnant women and their offspring. We aimed to provide substantial evidence for the effect of the BNT162b2 mRNA vaccine versus native infection on maternal humoral, as well as transplacentally acquired fetal immune response, potentially providing newborn protection.METHODSA multicenter study where parturients presenting for delivery were recruited at 8 medical centers across Israel and assigned to 3 study groups: vaccinated (n = 86); PCR-confirmed SARS-CoV-2 infected during pregnancy (n = 65), and unvaccinated noninfected controls (n = 62). Maternal and fetal blood samples were collected from parturients prior to delivery and from the umbilical cord following delivery, respectively. Sera IgG and IgM titers were measured using the Milliplex MAP SARS-CoV-2 Antigen Panel (for S1, S2, RBD, and N).RESULTSThe BNT162b2 mRNA vaccine elicits strong maternal humoral IgG response (anti-S and RBD) that crosses the placenta barrier and approaches maternal titers in the fetus within 15 days following the first dose. Maternal to neonatal anti-COVID-19 antibodies ratio did not differ when comparing sensitization (vaccine vs. infection). IgG transfer ratio at birth was significantly lower for third-trimester as compared with second trimester infection. Lastly, fetal IgM response was detected in 5 neonates, all in the infected group.CONCLUSIONAntenatal BNT162b2 mRNA vaccination induces a robust maternal humoral response that effectively transfers to the fetus, supporting the role of vaccination during pregnancy.FUNDINGIsrael Science Foundation and the Weizmann Institute Fondazione Henry Krenter.

Objective: To correlate the duration of Category II cardiotocograms (CTG) with adverse neonatal outcomes associated with perinatal asphyxia and determine the duration before fetal compromise.Study Design: This retrospective, observational study used electronic medical record data from a cohort of 271 patients, delivered by C-section due to non-reassuring fetal heart rate, at a tertiary medical center, from 2015 through 2017. Duration of Category II CTG, variability, tachycardia and deceleration frequency were analyzed and correlated to immediate postnatal outcomes. including cord pH ≤ 7, cord base excess >12, 1- and 5-min Apgar scores ≤7, need for ventilation, need for chest compressions, NICU admission, hypoglycemia and convulsions. Intrapartum fever and meconium stained amniotic fluid were correlated to the same outcomes. Categorical and continuous variables were analyzed using chi-square and t-tests, respectively. P < 0.05 was considered significant.Results: The mean duration of Category II CTG was 146 min (range 17-553). Longer duration did not result in increased rates of adverse neonatal outcomes. In contrast, reduced fetal heart rate (FHR) variability, fetal tachycardia and intrapartum fever did show increased rates of adverse neonatal outcomes, as follows: patients exhibiting reduced vs. normal (FHR) variability had 12.9% vs. 1.4% cord pH ≤ 7, P = 0.006 and 12.5% vs. 1.3% cord BE > 12, P = 0.004: patients with fetal tachycardia vs. normal baseline FHR exhibited 48% vs. 17.9% 1-minute Apgar score ≤7, P = 0.0004; 8% vs. 0.8% 5-minute Apgar score ≤7, P = 0.04; and 48% vs. 18.7% ventilation support, P < 0.001; patients with intrapartum fever vs. normal temperature, cord BE > 12 was seen in 9.7% vs. 1.7%, P = 0.035; 1-minute Apgar score was ≤7 in 35.5% vs. 18.7%, P = 0.03; 5-minute Apgar score ≤7 in 9.7% vs. 0.4%, P = 0.005; need for ventilation in 35.5% vs. 19.6%, P = 0.042; need for chest compressions in 6.45% vs. none, P = 0.013; and NICU admission in 12.9% vs. 2.5%, P = 0.018.Conclusions: Our results suggest that the duration of Category II CTG alone does not appear to predict perinatal asphyxia. Parameters associated with perinatal asphyxia are reduced FHR variability, fetal tachycardia and intrapartum fever. Therefore, when contemplating intervention during labor to avoid fetal asphyxia, these parameters should be strongly considered. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Background: Previous studies have documented an increased incidence of cardiac mortality and sudden death during winter months., Objectives: To evaluate seasonal variation in sudden death in a hot climate such as the desert region of southern Israel., Methods: We analyzed the files of 243 consecutive patients treated for out-of-hospital sudden death by the Beer Sheva Mobile Intensive Care Unit during 1989-90. Daily, monthly and seasonal incidence of sudden death was correlated with meteorological data, including temperature, heat stress, relative humidity and barometric pressure., Results: The seasonal distribution of sudden death was 23% in spring, 21% in summer, 25% in autumn and 31% in winter (not significant). In patients with known heart disease there were more episodes of sudden death in cold weather (< 15.4 degrees C) than hot (> 34.2 degrees C) (16 vs. 3, P < 0.05). Resuscitation was less successful in cold compared with hot weather (28 vs. 11, P < 0.05). Of patients older than 65 years, 11 sustained sudden death when heat stress was below 12.4 degrees C compared to 2 patients when heat stress was above 27.5 degrees C (P = 0.05)., Conclusion: Despite the warm desert climate, there were more cases of sudden death in older patients and in those with known heart disease during the winter season and on particularly cold days.
