RESUMO
AIM: To explore the correlation between a singular value of additive OGTT scores and adverse maternal and neonatal outcomes. We postulated that a higher additive OGTT score would predict poorer maternal and neonatal outcomes. METHODS: In this retrospective cohort study, data were collected from all women with a documented complete OGTT result and subsequent diagnosis of GDM. The additive OGTT score was calculated by adding each individual hourly glucose measurement. Maternal demographics, pregnancy and labor characteristics, and neonatal outcomes were compared between the lower-sum and higher-sum OGTT groups. A multivariate regression analysis was performed to identify confounders associated with adverse outcomes. RESULTS: In this study, a total of 1497 patients were assessed. The group with higher-sum OGTT scores was characterized by increased rates of GDMA2 (p = 0.008), higher insulin doses (p = 0.009), and higher rates of composite maternal and neonatal adverse outcomes (p = 0.021 and p = 0.030, respectively) compared to the lower-sum OGTT group. CONCLUSION: The additive OGTT score may aid in predicting the need for insulin treatment, labor course, and neonatal outcomes in GDM patients.
RESUMO
Exposure to excessive or uncontrolled stress is a major factor associated with various diseases including posttraumatic stress disorder (PTSD). The consequences of exposure to trauma are affected not only by aspects of the event itself, but also by the frequency and severity of trauma reminders. It was suggested that in PTSD, hippocampal-dependent memory is compromised while amygdala-dependent memory is strengthened. Several lines of evidence support the role of the endocannabinoid (eCB) system as a modulator of the stress response. In this study we aimed to examine cannabinoids modulation of the long-term effects (i.e., 1 month) of exposure to a traumatic event on memory and plasticity in the hippocampus and amygdala. Following exposure to the shock and reminders model of PTSD in an inhibitory avoidance light-dark apparatus rats demonstrated: (i) enhanced fear retrieval and impaired inhibitory extinction (Ext), (ii) no long-term potentiation (LTP) in the CA1, (iii) impaired hippocampal-dependent short-term memory in the object location task, (iv) enhanced LTP in the amygdala, and (v) enhanced amygdala-dependent conditioned taste aversion memory. The cannabinoid CB1/2 receptor agonist WIN55-212,2 (0.5mg/kg, i.p.) and the fatty acid amide hydrolase (FAAH) inhibitor URB597 (0.3mg/kg, i.p.), administered 2 hr after shock exposure prevented these opposing effects on hippocampal- and amygdala-dependent processes. Moreover, the effects of WIN55-212,2 and URB597 on Ext and acoustic startle were prevented by co-administration of a low dose of the CB1 receptor antagonist AM251 (0.5mg/kg, i.p.), suggesting that the preventing effects of both drugs are mediated by CB1 receptors. Exposure to shock and reminders increased CB1 receptor levels in the CA1 and basolateral amygdala 1 month after shock exposure and this increase was also prevented by administering WIN55-212,2 or URB597. Taken together, these findings suggest the involvement of the eCB system, and specifically CB1 receptors, in the opposite effects of severe stress on memory and plasticity in the hippocampus and amygdala.

Ample evidence demonstrates that fear learning contributes significantly to many anxiety pathologies including post-traumatic stress disorder (PTSD). The endocannabinoid (eCB) system may offer therapeutic benefits for PTSD and it is a modulator of the hypothalamic pituitary adrenal (HPA) axis. Here we compared the separated and combined effects of blocking glucocorticoid receptors (GRs) using the GR antagonist RU486 and enhancing CB1r signaling using the CB1/2 receptor agonist WIN55,212-2 in the CA1 and basolateral amygdala (BLA) on the consolidation of traumatic memory. Traumatic memory was formed by exposure to a severe footshock in an inhibitory avoidance apparatus followed by exposure to trauma reminders. Intra-BLA RU486 (10ng/side) and WIN55,212-2 (5µg/side) administered immediately after shock exposure dampened the consolidation of the memory about the traumatic event and attenuated the increase in acoustic startle response in rats exposed to shock and reminders. In the CA1, WIN55,212-2 impaired consolidation and attenuated the increase in acoustic startle response whereas RU486 had no effect. The effects of WIN55,212-2 were found to be mediated by CB1 receptors, but not by GRs. Moreover, post-shock systemic WIN55,212-2 (0.5mg/kg) administration prevented the increase in GRs and CB1 receptor levels in the CA1 and BLA in rats exposed to shock and reminders. The findings suggest that the BLA is a locus of action of cannabinoids and glucocorticoids in modulating consolidation of traumatic memory in a rat model of PTSD. Also, the findings highlight novel targets for the treatment of emotional disorders and PTSD in particular.

BACKGROUND: Induction of labor with an extra-amniotic balloon catheter is a procedure commonly associated with maternal discomfort, pain, and anxiety. OBJECTIVE: We aimed to investigate the distractive effect of virtual reality technology on pain and anxiety among pregnant patients who underwent induction of labor with an extra-amniotic balloon catheter. STUDY DESIGN: In this randomized controlled trial, pregnant patients who were undergoing planned induction of labor using an extra-amniotic balloon catheter at term for various obstetrical indications were recruited and randomized in a 1:1 ratio into 2 groups. Patients in the virtual reality group were exposed to a virtual reality technology clip (using SootheVR All-In-One virtual reality care system for pain and anxiety) during the entire extra-amniotic balloon catheter insertion, whereas patients in the control group received the institutional standard care for extra-amniotic balloon catheter insertion. Pain scores, expressed as visual analog scale scores, and maternal hemodynamic parameters were obtained before, during, and after extra-amniotic balloon catheter insertion. Anxiety was evaluated using the validated State-Trait Anxiety Inventory Scale before and after the procedure. Maternal satisfaction with the virtual reality technology was also recorded. The primary outcome was the change in visual analog scale score before and during extra-amniotic balloon catheter insertion. Among the secondary outcomes was the change in anxiety levels before and after extra-amniotic balloon catheter insertion. The study was powered to detect a 25% decrease in the primary outcome. RESULTS: A total of 132 pregnant patients were recruited (66 in each group). There were no differences between groups in terms of age, body mass index, gestational age at enrollment, indication for induction of labor, and preprocedural visual analog scale score and anxiety levels. The change in visual analog scale score (maximal visual analog scale score during the procedure minus the initial visual analog scale score before the procedure, ie, the primary outcome) was significantly lower in the virtual reality group than in the control group (2.78±3.0 vs 4.09±2.99; P=.01). In addition, the virtual reality group experienced a higher rate of anxiety relief, expressed as the difference between the preprocedure and postprocedure State-Trait Anxiety Inventory Scale scores (-6.46±9.6 vs -2.01±9.11; P=.007). Patients in the virtual reality group reported a very high overall (94%) satisfaction score. CONCLUSION: In this randomized controlled trial, we demonstrated that the use of virtual reality technology among patients who underwent induction of labor using an extra-amniotic balloon catheter was associated with lower visual analog scale scores during the procedure and a significant reduction in anxiety than patients who received standard care. There was also a very high satisfaction rate with the use of virtual reality technology.

BACKGROUND: Patients with primary ciliary dyskinesia (PCD) have chronic morbidities affecting their quality of life (QOL). Health-related QOL (HRQOL) has been recognized as an important tool for assessing the burden of PCD on patients and their families. A PCD-specific HRQOL questionnaire (QOL-PCD) was developed and validated for the English-speaking populations. Still, it has not yet been translated into Hebrew or adapted for Israeli PCD patients. METHODS: This describes our translation of the original English version of QOL-PCD into a Hebrew version. The process involved forward translation by independent translators, construction of a consensus version, back-translation into the original English version, analysis by the expert committee, and a pretest. The pretest was administered to 20 participants with PCD (the patients and the parents of minor patients) to assess the feasibility and practicality of the tool. Scale and item indices (scale-level content validity index [S-CVI] and item-level content validity index [I-CVI]) were calculated for content validity. RESULTS: All study participants understood the final Hebrew version that the expert committee had approved with no difficulty. The instrument had satisfactory (>0.80) content validity, with S-CVI indexes of 0.99 for the adult version, 0.86 for the parental version, 0.95 for the adolescent version, and 1.00 for the child version. CONCLUSION: The English version of a QOL-PCD was translated into Hebrew and adapted in Israel. This translation is a valid instrument to assess HRQOL in Hebrew-speaking patients with PCD and their family members. It may be helpful for PCD patient management and research in Israel.

OBJECTIVES: Coronavirus Disease 2019 (COVID-19) is a highly infectious viral pandemic that has claimed the lives of millions. Personal protective equipment (PPE) may reduce the risk of transmission for health care workers (HCWs), especially in the emergency setting. This study aimed to compare the adherence to PPE donning and doffing protocols in the Emergency Department (ED) vs designated COVID-19 wards and score adherence according to the steps in our protocol. DESIGN: Prior to managing COVID-19 patients, mandatory PPE training was undertaken for all HCWs. HCWs were observed donning or doffing COVID-19 restricted areas. SETTING: Donning and doffing was observed in COVID-19 designated Emergency department and compared to COVID-19 positive wards. PARTICIPANTS: All HCWs working in the aforementioned wards during the time of observation. RESULTS: We observed 107 donning and doffing procedures (30 were observed in the ED). 50% HCWs observed donned PPE correctly and 37% doffed correctly. The ED had a significantly lower mean donning score (ED: 78%, Internal: 95% ICU: 96%, p < 0.001); and a significantly lower mean doffing score (ED: 72%, Internal: 85% ICU: 91%, p = 0.02). CONCLUSIONS: As hypothesized, HCWs assigned to the designated ED wing made more protocol deviations compared with HCWs positive COVID-19 wards. Time management, acuity, lack of personnel, stress and known COVID-19 status may explain the lesser adherence to donning and doffing protocols. Further studies to assess the correlation between protocol deviations in use of PPE and morbidity as well as improvement implementations are required. Resources should be invested to ensure PPE is properly used.

Posttraumatic stress disorder (PTSD) is a debilitating condition highly comorbid with depression. The endocannabinoid (eCB) system and brain-derived neurotrophic factor (BDNF) are suggestively involved in both disorders. We examined whether cannabinoids can prevent the long-term depressive-like symptoms induced by exposure to the shock and situational reminders (SRs) model of PTSD. The CB1/2 receptor agonist WIN55,212-2 (0.5â¯mg/kg; i.p.), the fatty acid hydrolase (FAAH) inhibitor URB597 (0.3â¯mg/kg, i.p.) or vehicle were administered 2â¯h after severe shock. Cannabinoids prevented the shock/SRs-induced alterations in social recognition memory, locomotion, passive coping, anxiety-like behavior, anhedonia, fear retrieval, fear extinction and startle response as well as the decrease in BDNF levels in the hippocampus and prefrontal cortex (PFC). Furthermore, significant correlations were found between depressive-like behaviors and BDNF levels in the brain. The findings suggest that cannabinoids may prevent both depressive- and PTSD-like symptoms following exposure to severe stress and that alterations in BDNF levels in the brains' fear circuit are involved in these effects.

The present study examined the effects of orthographic transparency on reading ability of children with dyslexia in two Hebrew scripts. The study explored the reading accuracy and speed of vowelized and unvowelized Hebrew words of fourth-grade children with dyslexia. A comparison was made to typically developing readers of two age groups: a group matched by chronological age and a group of children who are 2 years younger, presumably at the end of the reading acquisition process. An additional purpose was to investigate the role of vowelization in the reading ability of unvowelized script among readers with dyslexia in an attempt to assess whether vowelization plays a mediating role for reading speed of unvowelized scripts. The present study found no significant differences in reading accuracy and speed between vowelized and unvowelized scripts among fourth-grade readers with dyslexia. The reading speed of fourth-graders with dyslexia was similar to typically developing second-graders for both the vowelized and unvowelized words. However, fourth-grade children with dyslexia performed lower than the typically developing second-graders in the reading accuracy of vowelized script. Furthermore, for readers with dyslexia, accuracy in reading both vowelized and unvowelized words mediated the reading speed of unvowelized scripts. These results may be a sign that Hebrew-speaking children with dyslexia have severe difficulties that prevent them from developing strategies for more efficient reading.
