Objective Advanced Trauma Life Support guidelines recommend only 1 L of intravenous (IV) crystalloid before transitioning to blood products. We sought to determine if receiving >1 L of IV crystalloid during the initial resuscitation is associated with worse outcomes. We also sought to determine if receiving no crystalloids is associated with better outcomes. Methods We performed a single center retrospective study using trauma registry data, which was supplemented by manual chart review. We only included patients who had an initial heart rate ≥ 100 beats/min or a systolic blood pressure ≤ 90 mmHg. For each patient, we determined the total amount of IV crystalloid administered in the first 3 h after arrival to the hospital plus prehospital crystalloid. We performed multivariate regression analyses to determine if there is an association between the administration of >1 L of crystalloids or no crystalloids with in-hospital mortality, hospital length of stay (LOS), or packed red blood cells (PRBCs) transfused. Results Between January 1, 2018 and September 30, 2019, there were 878 who met criteria for enrollment. Among those, 55.0% received ≤1 L of IV crystalloids, and 45.0% received >1 L. Multivariate analyses showed no significant association between receiving >1 L and mortality (p = 0.61) or PRBCs transfused (p = 0.29), but patients who received >1 L had longer hospital LOS (p = 0.04). We found no association between receiving no crystalloids and mortality, PRBCs transfused, or LOS. Conclusion On a multivariate analysis of trauma patients, we did not find an association between the administration of >1 L of IV crystalloid and in-hospital mortality or the volume of PRBCs transfused. However, receiving >1 L of crystalloids was associated with a longer hospital LOS. We found no benefit to completely withholding crystalloids.

Background Physiologic hyperglycemia of puberty is a major contributor to poor glycemic control in youth with type 1 diabetes (T1D). This study’s aim was to determine the effectiveness of continuous glucose monitoring (CGM) to improve glycemic control in pubertal youth with T1D compared to a non-CGM cohort after controlling for age, sex, BMI, duration, and insulin delivery methodology. The hypothesis is that consistent CGM use in puberty improves compliance with diabetes management, leading to increased percentage (%) time in range (TIR70–180 mg/dL) of glycemia, and lowering of HbA1c. Methods A longitudinal, retrospective, case-controlled study of 105 subjects consisting of 51 T1D controls (60.8% male) age 11.5 ± 3.8 y; and 54 T1D subjects (48.1% male) age 11.1 ± 5.0 y with confirmed CGM use for 12 months. Pubertal status was determined by Tanner staging. Results were adjusted for baseline HbA1c and diabetes duration. Results HbA1c was similar between the controls and the CGM group at baseline: 8.2 ± 1.1% vs 8.3 ± 1.2%, p=0.48 respectively; but was significantly lower in the CGM group 12 months later, 8.2 ± 1.1% vs. 8.7 ± 1.4%, p=0.035. Longitudinal change in HbA1c was similar in the prepubertal cohort between the control- and CGM groups: −0.17 ± 0.98% vs. 0.38 ± 1.5%, p=0.17. In contrast, HbA1c increased with advancing age and pubertal status in the pubertal controls but not in the pubertal CGM group: 0.55 ± 1.4 vs −0.22 ± 1.1%, p=0.020. Percent TIR was inversely related to HbA1c in the CGM group, r=-0.6, p=0.0004, for both prepubertal and pubertal subjects. Conclusions CGM use significantly improved glycemic control in pubertal youth with T1D compared to non-CGM users.

ImportanceThere is no consensus on the impact of the 2020 COVID-19 pandemic lockdown on glycemic control in children and adolescents with type 1 diabetes (T1D) in the US.AimTo determine the impact of the pandemic lockdown of March 15th through July 6th, 2020 on glycemic control after controlling for confounders.Subjects and MethodsAn observational study of 110 subjects of mean age 14.8 ± 4.9 years(y), [male 15.4 ± 4.0y, (n=57); female 14.1 ± 3.8y, (n=53), p=0.07] with T1D of 6.31 ± 4.3y (95% CI 1.0-19.7y). Data were collected at 1-4 months before the lockdown and 1-4 months following the lifting of the lockdown at their first post-lockdown clinic visit.ResultsThere was no significant change in A1c between the pre- and post-pandemic lockdown periods, 0.18 ± 1.2%, (95% CI -0.05 to 0.41), p=0.13. There were equally no significant differences in A1c between the male and female subjects, -0.16 ± 1.2 vs -0.19 ± 1.2%, p=0.8; insulin pump users and non-pump users, -0.25 ± 1.0 vs -0.12 ± 1.4%, p=0.5; and pubertal vs prepubertal subjects, 0.18 ± 1.3 vs -0.11 ± 0.3%, p=0.6. The significant predictors of decrease in A1c were pre-lockdown A1c (pConclusionsThere was no change in glycemic control during the pandemic lockdown of 2020 in US children.

To determine the effect of sex and neuter status on trauma survival in dogs.Multi-institutional prospective case series, September 2013 to March 2019, retrospectively analyzed.Level I and II Veterinary Trauma Centers.Consecutive sample of 2649 dogs in the American College of Veterinary Emergency and Critical Care Veterinary Committee on Trauma patient registry meeting inclusion criteria. For inclusion, dogs had to have complete data entries, be postpubertal (≥7 months age in females and ≥10 months age in males), and have sustained moderate to severe trauma (animal trauma triage [ATT] score ≥5/18). Dogs that were dead upon arrival, euthanized for financial or unknown reasons alone, or that were presented by a Good Samaritan but subsequently humanely euthanized were excluded.Data collected included age, sex, neuter status (intact, neutered), trauma type (blunt, penetrating, both), outcome (survived to hospital discharge, died, euthanized), and reason for euthanasia (grave prognosis, financial reasons, or both). Of 2649 eligible dogs, 56% survived to hospital discharge (n = 1469). Neutered females had a significantly higher survival rate (58.3% vs 51.3%; P = 0.03) compared to intact females, and neutered males had a significantly higher survival rate (56.6% vs 50.7%; P = 0.04) compared to intact males. There was no significant difference in survival between intact females and intact males (P = 0.87) or between neutered females and neutered males (P = 0.46). Mean cumulative ATT score was higher in intact groups and was found to be a significant predictor of survival (P 0.01). Based on logistic models, overall odds of survival were 20.7% greater in neutered dogs.Gonadectomy is associated with lower ATT scores and improved survival after moderate to severe trauma in both female and male dogs.

Objectives The is no consensus on the early patterns of lipid-based cardiovascular disease (CVD) risk in youth with either type 1 diabetes (T1D) or type 2 diabetes (T2D). The aim was todetermine the differences in CVD risk, using lipid profiles, in children and adolescents with either T1D or T2D at the time of their first lipid assessment, after stratifying the T1D cohort into remitters and non-remitters based on their honeymoon history. Methods A cross-sectional study of 249 subjects consisting of 73 controls, 53 T2D subjects, and 123 T1D subjects stratified into remitters (n=44), and non-remitters (n=79). Partial clinical remission (PCR) was defined as insulin-dose adjusted HbA1c of ≤9. Pubertal status was determined by Tanner staging. Results After adjusting for age, sex, BMI, race, and pubertal status, T2D patients had significantly higher LDL-C compared to the controls (p=0.022), the remitters (p=0.029), but not the non-remitters (103.1 ± 5.9 mg/dL vs. 91.4 ± 4.2 mg/dL, p=0.49). Similarly, T2D patients had significantly higher non-HDL-C compared to the controls (p=0.006), the remitters (p=0.0002), but not the non-remitters (137.6 ± 7.1 mg/dL vs. 111.71 ± 5.0 mg/dL, p=0.053). Total cholesterol was also significantly higher in T2D patients compared to the controls (p=0.0005), the remitters (p=0.006) but not the non-remitters (183.5 ± 6.6 mg/dL vs. 166.2 ± 4.8 mg/dL, p=0.27). Conclusions Lack of the honeymoon phase in children and adolescents with T1D confers early and significantly increased lipid-based cardiovascular risk to these patients that is similar to the elevated cardiovascular risk seen in T2D.

Background Serum lactate increases in states of severe sepsis and shock, but its interpretation may be subject to confounders. Lactated Ringer's solution (LR) is used in the resuscitation of septic patients and contains 28 mmol/L of sodium lactate. Objectives We sought to determine if a bolus of 30 mL/kg of LR increases serum lactate levels. Methods In this double-blind, randomized controlled trial, 30 volunteers were assigned to receive either 30 mL/kg of intravenous LR or normal saline (NS). Serum lactate was measured before and after the fluid bolus. The primary outcome was the difference in the change in lactate between the LR and NS groups. Secondarily, we assessed the change in pH, bicarbonate, sodium, and chloride in each group. Results After 30 mL/kg of intravenous LR, the mean serum lactate level increased by 0.93 mmol/L (95% confidence interval 0.42–1.44 mmol/L). However, there was also a small increase in the mean serum lactate level in the NS group of 0.37 mmol/L (95% confidence interval −0.26 mmol/L to 1.00 mmol/L), such that there was not a statistically significant difference in the change in lactate when comparing the LR group to the NS group (p = 0.2). The NS group saw larger declines in pH and bicarbonate and greater increases in chloride compared with the LR group. Conclusion In healthy individuals, a modest but significant rise in mean serum lactate was seen after a 30 cc/kg LR bolus. There was no difference in mean serum lactate when comparing a 30 mL/kg bolus of NS to LR.

Background Urgent care centers (UCCs) can offer a cheap alternative to emergency departments (EDs) for some patients with acute complaints. However, if patients who initially present to a UCC are unnecessarily transferred to an ED, those patients may suffer undue financial harm. The group of patients transferred from UCCs to EDs have never previously been studied. Objectives The primary objective of this study was to determine the fraction of transfers from a UCC to an ED that were unnecessary. We also assessed the frequency with which these patients were discharged from the ED, and tried to determine which groups of patients were most likely to be unnecessarily transferred. Methods This was a retrospective chart review performed on patients transferred from UCCs to our ED. If the transferred patient had no advanced imaging tests, advanced procedures, or specialty consultations in the ED, and was not admitted, we considered the transfer to be unnecessary. Patients were stratified by age (adult vs. pediatric) and type of insurance. Results We identified 3232 patients who were transferred from UCCs to our ED over a 1-year period. Among those, 1159 (35.9%; 95% confidence interval [CI] 34.2–37.5%) met our criteria as unnecessary, and 2075 (64.2%; 95% CI 62.5–65.8%) were discharged from the ED. Notably, pediatric patients were more likely than adult patients to be unnecessarily transferred. Patients without medical insurance were not more likely to be transferred than those with private insurance. Conclusion Most patients transferred to our ED from a UCC were discharged, and many transfers were unnecessary, especially those involving pediatric patients. These transfers may represent an economic burden to our society.

Rejections differ. For those who are rejected, one important difference is whether they are rejected for someone else (comparative rejection) or no one at all (noncomparative rejection). We examined the effect of this distinction on emotional reactions to a rejection in four studies ( N = 608), one of which was fully preregistered. Our results show that comparative rejections feel worse than noncomparative rejections and that this may be because such rejections lead to an increased sense of exclusion and decreased belonging. Furthermore, we found evidence that, by default, people react to a rejection as though it were comparative-that is, in the absence of any information about whether they have been rejected for someone or no one, they react as negatively as if they were rejected for someone. Our discussion focuses on the implications of these findings, including why people often seek out information in the wake of a rejection.

BackgroundMany emergency physicians use an intravenous fluid bolus as part of a ‘cocktail’ of therapies for patients with headache, but it is unclear if this is beneficial. The objective of this study was to determine if an intravenous fluid bolus helps reduce pain or improve other outcomes in patients who present to the ED with a benign headache.MethodsThis was a randomised, single-blinded, clinical trial performed on patients aged 10–65 years old with benign headaches who presented to a single ED in Las Vegas, Nevada, from May 2017 to February 2019. All patients received prochlorperazine and diphenhydramine, and they were randomised to also receive either 20 mL/kg up to 1000 mL of normal saline (the fluid bolus group) or 5 mL of normal saline (the control group). The primary outcome was the difference between groups in mean pain reduction 60 min after the initiation of treatment. Secondarily, we compared groups with regards to pain reduction at 30 min, nausea scores, the use of rescue medications and disposition.ResultsWe screened 67 patients for enrolment, and 58 consented. Of those, 35 were randomised to the fluid bolus group and 23 to the control group. The mean pain score dropped by 48.3 mm over 60 min in the fluid bolus group, compared with 48.7 mm in the control group. The between groups difference of 0.4 mm (95% CI −16.5 to 17.3) was not statistically significant (p=0.96). Additionally, no statistically significant difference was found between groups for any secondary outcome.ConclusionThough our study lacked statistical power to detect small but clinically significant differences, ED patients who received an intravenous fluid bolus for their headache had similar improvements in pain and other outcomes compared with those who did not.Trial registration numberNCT03185130.

Background Recent data have challenged the notion that rapid intravenous fluid administration results in adverse neurologic outcomes in children with diabetic ketoacidosis (DKA). While many physicians still administer a cautious 10 cc/kg bolus of intravenous fluids for pediatric DKA patients, there may be benefits to using a larger bolus. Methods This was a retrospective chart review of all pediatric patients with DKA presenting to a single emergency department (ED) between 2013 and 2015. Patients who received a bolus of 10 cc/kg or less in the ED were compared to patients who received >10 cc/kg of fluids. The primary outcome was the difference in hospital length-of-stay between the two groups. Secondarily, we compared groups with regards to the time to bicarbonate normalization. Results In sum, 170 pediatric DKA ED visits were analyzed. Patients who received a 10 cc/kg bolus or less of fluids in the ED had a mean hospital length-of-stay > that was 0.38 days longer (95% CI: 0.006 to 0.75 days) than those who received >10 cc/kg. On multivariable regression analysis, the difference between groups was diminished and no longer statistically significant. The time to bicarbonate normalization was 0.12 days longer (95% CI -0.029 to 0.27) in the 10 cc/kg or less group than the >10 cc/kg group. Conclusions After adjustment for confounders, no statistically significant differences in outcomes were seen in pediatric DKA patients who received a 10 cc/kg bolus or less compared to those who received a larger initial bolus.

Author(s): Marshall, Travis; Chen, Nae Meng; Nguyen, Eric; Slattery, David E.; Zitek, Tony | Abstract: Introduction: Computed tomography pulmonary angiography (CTPA) is the test of choice for diagnosis of pulmonary embolism (PE) in the emergency department (ED), but this test may be indeterminate for technical reasons such as inadequate contrast filling of the pulmonary arteries. Many hospitals have requirements for intravenous (IV) catheter size or location for CTPAs to reduce the chances of inadequate filling, but there is a lack of clinical data to support these requirements. The objective of this study was to determine if a certain size or location of IV catheter used for contrast for CTPA is associated with an increased chance of an indeterminate CTPA. Methods: This was a retrospective chart review of patients who underwent CTPA in the emergency department. A CTPA was considered indeterminate if the radiology report indicated it was inadequate to exclude a pulmonary embolism. The reason for the study being indeterminate, and the size and location of the IV catheter were abstracted. The rate of inadequate contrast filling of the pulmonary vasculature was calculated and compared for various IV catheter sizes and locations. In particular, 20-gauge or larger IV catheters in the antecubital fossa or forearm were compared to all other sizes and locations. Results: A total of 19.3% of the 1500 CTPA reports reviewed met our criteria as indeterminate, and 51.6% of those were due to inadequate filling. Patients with a 20-gauge IV catheter or larger placed in the antecubital fossa or forearm had inadequate filling 9.2% of the time compared to 13.2% for patients who had smaller IVs or IVs in other locations (difference: 4.0% [95% CI -1.7% to 9.7%]). There were also no statistically significant differences in the rates of inadequate filling when data were further stratified by IV catheter location and size. Conclusion: We did not detect any statistically significant differences in the rate of inadequate contrast filling based on IV catheter locations or sizes. While small differences not detected in this study may exist, it seems prudent to proceed with CTPA in patients with difficult IV access who need emergent imaging even if they have a small or distally located IV.

In recent decades, an increasing number of studies have aimed to shed light on the origin and spread of tuberculosis in past human populations. Here we present the results of a systematic palaeodemographic and palaeopathological survey of the Early Mediaeval population of Gars/Thunau (Lower Austria), which - at this stage - includes 373 individuals recovered at two archaeological sub-sites: a fortified settlement (including a necropolis) at the top of a hill - probably reserved for social and military elites; and a large riverine settlement at the foot of the hill, a so-called 'suburbium', where burials and an area of 'industrial' character were discovered. We recorded a great number of pathological alterations and a variety of 'classical' features of tuberculosis, such as vertebral destructions (Pott's disease) and joint destructions, and other pathological (unspecific) features probably linked with Mycobacterium tuberculosis infection (e.g. new bone formation at the inner surface of the ribs, endocranial alterations in the form of 'pits', and new bone formation at the cranial base). We hypothesize that the two contemporaneous (∼900-1000 AD) populations of Gars/Thunau differed not only in their social affiliation/condition, but also in the type and frequencies of their population-density-related infectious diseases (in particular tuberculosis). Moreover, we investigated the molecular genetic evidence of the causative organism in a few selected immatures exhibiting pathological changes at the inner wall of the cranium and discuss these findings in regard to the macroscopic features observed. Finally, we analysed carbon and nitrogen stable isotopes of both populations and strontium isotope ratios of the hill-top inhabitants in order to reconstruct certain aspects of diet and mobility to test our hypothesis concerning the specific social and/or military character of the site.

Author(s): Zitek, Tony; Busby, Elizabeth; Hudson, Heather; McCourt, John D.; Baydoun, Jamie; Slattery, David E. | Abstract: Introduction: The peripheral internal jugular (IJ), also called the “easy IJ,” is an alternative to peripheral venous access reserved for patients with difficult intravenous (IV) access. The procedure involves placing a single-lumen catheter in the IJ vein under ultrasound (US) guidance. As this technique is relatively new, the details regarding the ease of the procedure, how exactly it should be performed, and the safety of the procedure are uncertain. Our primary objective was to determine the success rate for peripheral IJ placement. Secondarily, we evaluated the time needed to complete the procedure and assessed for complications.Methods: This was a prospective, single-center study of US-guided peripheral IJ placement using a 2.5-inch, 18-gauge catheter on a convenience sample of patients with at least two unsuccessful attempts at peripheral IV placement by nursing staff. Peripheral IJ lines were placed by emergency medicine (EM) attending physicians and EM residents who had completed at least five IJ central lines. All physicians who placed lines for the study watched a 15-minute lecture about peripheral IJ technique. A research assistant monitored each line to assess for complications until the patient was discharged. Results: We successfully placed a peripheral IJ in 34 of 35 enrolled patients (97.1%). The median number of attempts required for successful cannulation was one (interquartile range (IQR): 1 to 2). The median time to successful line placement was 3 minutes and 6 seconds (IQR: 59 seconds to 4 minutes and 14 seconds). Two lines failed after placement, and one of the 34 successfully placed peripheral IJ lines (2.9%) had a complication – a local hematoma. There were, however, no arterial punctures or pneumothoraces. Although only eight of 34 lines were placed using sterile attire, there were no line infections. Conclusion: Our research adds to the growing body of evidence supporting US-guided peripheral internal jugular access as a safe and convenient procedure alternative for patients who have difficult IV access.

Study objective Intravenous subdissociative-dose ketamine has been shown to be effective for pain management, but has not been specifically studied for headaches in the emergency department (ED). For this reason, we designed a study to compare standard treatment (prochlorperazine) with ketamine in patients with benign headaches in the ED. Methods This study was a multicenter, double-blind, randomized, controlled trial with a convenience sample of patients presenting to the ED with benign headaches. Patients were randomized to receive either prochlorperazine and diphenhydramine or ketamine and ondansetron. Patients' headache severity was measured on a 100-mm visual analog scale (VAS) at 0, 15, 30, 45, and 60 minutes. Nausea, vomiting, anxiety, and the need for rescue medications were also tracked. Patients were contacted at 24 to 48 hours posttreatment to rate their satisfaction and to determine whether they were still experiencing a headache. Results There were a total of 54 subjects enrolled. Two patients in the ketamine group and one in the prochlorperazine group withdrew because of adverse effects of the medications. In regard to the primary outcome, at 60 minutes, the prochlorperazine group had a mean improvement in VAS pain scores of 63.5 mm compared with 43.5 mm in the ketamine group, corresponding to a between-groups difference of 20.0 mm (95% confidence interval [CI] 2.8 to 37.2 mm) and a P value of .026. At 45 minutes, the prochlorperazine group had a mean improvement in pain scores of 56.1 mm compared with 38.0 mm in the ketamine group, a difference of 18.1 mm (95% CI 1.0 to 35.2 mm). At 24- to 48-hour follow-up, the mean satisfaction score was 8.3 of 10 for prochlorperazine and 4.9 of 10 for ketamine, a difference of 3.4 (95% CI 1.2 to 5.6). There was not a statistically significant difference in the percentage of patients who had a headache at follow-up or in other secondary outcomes. Conclusion Prochlorperazine appears to be superior to ketamine for the treatment of benign headaches in the ED.

We tested the hypothesis that social hierarchies are fluent social stimuli; that is, they are processed more easily and therefore liked better than less hierarchical stimuli. In Study 1, pairs of people in a hierarchy based on facial dominance were identified faster than pairs of people equal in their facial dominance. In Study 2, a diagram representing hierarchy was memorized more quickly than a diagram representing equality or a comparison diagram. This faster processing led the hierarchy diagram to be liked more than the equality diagram. In Study 3, participants were best able to learn a set of relationships that represented hierarchy (asymmetry of power)--compared to relationships in which there was asymmetry of friendliness, or compared to relationships in which there was symmetry--and this processing ease led them to like the hierarchy the most. In Study 4, participants found it easier to make decisions about a company that was more hierarchical and thus thought the hierarchical organization had more positive qualities. In Study 5, familiarity as a basis for the fluency of hierarchy was demonstrated by showing greater fluency for male than female hierarchies. This study also showed that when social relationships are difficult to learn, people's preference for hierarchy increases. Taken together, these results suggest one reason people might like hierarchies--hierarchies are easy to process. This fluency for social hierarchies might contribute to the construction and maintenance of hierarchies.

Although advances have been made in the approach to airway management, intubating critically ill patients in the Emergency Department (ED) can still be perilous. In some cases, poor peripheral perfusion may preclude obtaining a consistent or reliable pulse oximetry waveform, and the intubator will not accurately know when the patient begins to desaturate. We describe a case of a patient requiring intubation in whom we were unable to obtain a consistent pulse oximetry waveform. We utilized a novel technique in which a Biphasic Cuirass Ventilation (BCV) device was applied to maintain oxygenation and ventilation during the performance of rapid sequence intubation (RSI). This technique has the potential to improve the safety of RSI, especially in the critically ill patient.

Introduction: Two-point compression ultrasound is purportedly a simple and accurate means to diagnose proximal lower extremity deep vein thrombosis (DVT), but the pitfalls of this technique have not been fully elucidated. The objective of this study is to determine the accuracy of emergency medicine resident-performed two-point compression ultrasound, and to determine what technical errors are commonly made by novice ultrasonographers using this technique. Methods: This was a prospective diagnostic test assessment of a convenience sample of adult emergency department (ED) patients suspected of having a lower extremity DVT. After brief training on the technique, residents performed two-point compression ultrasounds on enrolled patients. Subsequently a radiology department ultrasound was performed and used as the gold standard. Residents were instructed to save videos of their ultrasounds for technical analysis. Results: Overall, 288 two-point compression ultrasound studies were performed. There were 28 cases that were deemed to be positive for DVT by radiology ultrasound. Among these 28, 16 were identified by the residents with two-point compression. Among the 260 cases deemed to be negative for DVT by radiology ultrasound, 10 were thought to be positive by the residents using two-point compression. This led to a sensitivity of 57.1% (95% CI [38.8-75.5]) and a specificity of 96.1% (95% CI [93.8-98.5]) for resident-performed two-point compression ultrasound. This corresponds to a positive predictive value of 61.5% (95% CI 42.8% to 80.2%) and a negative predictive value of 95.4% (95% CI 92.9% to 98.0%). The positive likelihood ratio is 14.9 (95% CI 7.5 to 29.5) and the negative likelihood ratio is 0.45 (95% CI 0.29 to 0.68). Video analysis revealed that in four cases the resident did not identify a DVT because the thrombus was isolated to the superior femoral vein (SFV), which is not evaluated by two-point compression. Moreover, the video analysis revealed that the most common mistake made by the residents was inadequate visualization of the popliteal vein. Conclusion: Two-point compression ultrasound does not identify isolated SFV thrombi, which reduces its sensitivity. Moreover, this technique may be more difficult than previously reported, in part because novice ultrasonographers have difficulty properly assessing the popliteal vein.

Background The role of stress in reproduction, particularly during treatment for infertility, has been of considerable interest; however, few studies have objectively measured stress and anxiety over the course of the IVF cycle or compared the experience of first-time and repeat patients. Methods This prospective cohort pilot study enrolled 44 women undergoing IVF at a university-based clinic to complete the State-Trait Anxiety Inventory (STAI), Perceived Stress Scale (PSS) and Infertility Self-Efficacy Scale (ISES) at three time points prior to ovarian stimulation (T1), one day prior to oocyte retrieval (T2), and 5–7 days post embryo transfer (T3). Results Mean STAI State scores were significantly elevated at all three time points (p

Three experiments demonstrated that feeling wronged leads to a sense of entitlement and to selfish behavior. In Experiment 1, participants instructed to recall a time when their lives were unfair were more likely to refuse to help the experimenter with a supplementary task than were participants who recalled a time when they were bored. In Experiment 2, the same manipulation increased intentions to engage in a number of selfish behaviors, and this effect was mediated by self-reported entitlement to obtain positive (and avoid negative) outcomes. In Experiment 3, participants who lost at a computer game for an unfair reason (a glitch in the program) requested a more selfish money allocation for a future task than did participants who lost the game for a fair reason, and this effect was again mediated by entitlement.

Throughout most of their lives, women are at greater risk for depression than men. Hormones and neurotransmitters share common pathways and receptor sites in areas of the brain linked to mood, particularly through the hypothalamic-pituitary-gonadal axis. It has been hypothesized that women presenting with episodes of depression associated with reproductive events (i.e., premenstrual, postpartum, menopausal transition) may be particularly prone to experiencing depression, in part because of a heightened sensitivity to intense hormonal fluctuations. The menopausal transition, for example, appears to represent a window during which some women might be more vulnerable to the development of first onset or recurrent depressive symptoms and major depressive episodes. In this review, we examine the association between hormone changes and increased risk of developing depression. Some of the underlying mechanisms that may contribute to such an increased risk are discussed critically, with a special emphasis on the events occurring during the menopausal transition. Last, we explore some of the clinical and therapeutic implications of hormone-modulated depression in women.

Repeated serological investigations (CFT, IFT, ELISA) of 50,000 pregnant women revealed that 5.1/1000 pregnancies in the Karviná district, Czech Republic are threatened by toxoplasmosis. In 2.8/1000 pregnancies the infection was contracted shortly before pregnancy, one third of them ended by spontaneous abortion. In this group the birth of a congenitally infected infant is rare. Primary infections of women who are already pregnant (2.3/1000 of pregnancies) are much more serious. This number comprises 1.2/1000 pregnancies with a spontaneous abortion and 1.2/1000 pregnancies leading to the delivery of a congenitally infected infant. By early detection, i.e. repeated serological examinations in all pregnancies, and by treatment of patients with Toxoplasma infections this hazard can be reduced substantially, i.e. to one eighth.

All the above listed reasons as well as the experience we have obtained with this method, justify our recommendation of the introduction of the laboratory diagnosis of scabies through the method of lye scraping of the skin into routine practice. A single parasite element is enough for determining the diagnosis while, for the above mentioned reasons, a negative microscope finding does not exclude the parasitic etiology of the given disease. We therefore recommend in the diagnosis of scabies that the following criteria are parallely used: 1. an objective skin finding 2. laboratory proof of the causative agent of infestation 3. subjective feelings of the patient (itching at the typical time) 4. positive epidemiological anamnesis, primarily the occurrence of clinical symptoms in several members of a family or a group 5. diminishing of clinical symptoms after specific treatment with an anti-scabies medicament.

Between September 1955 and January 1990, 94 pediatric patients were managed for renovascular hypertension caused by renal artery occlusive disease. Patients (50 boys and 44 girls) were aged 4 days to 17 years (median age: 7 years). At initial evaluation, 34 patients had symptoms of hypertensive encephalopathy or acute heart failure, 36 had moderate symptoms, and 24 were symptom-free. Sixty-five cases were classified on the basis of clinical, radiological, and histological features, as follows: neurofibromatosis (17), fibromuscular dysplasia (11), diffuse arterial calcified elastopathy (11), renal artery thrombosis (10), Williams syndrome (4), Takayashu disease (3), and miscellaneous diseases (9). In the 29 remaining patients, classification was based only on radiological features: causes included unilateral renal artery stenosis (15), bilateral renal artery stenosis with or without aortic stenosis (11), and miscellaneous disorders (3). Surgical treatment consisted in 47 renal revascularization, procedures (14 aortorenal bypasses, 8 aortorenal reimplantations, 9 anastomoses in the upper mesenteric arterial system, 7 autotransplantations, 4 resection-reanastomosis procedures, and 5 miscellaneous procedures). Renal revascularization failed in 15 cases (32%) (because of thrombosis in 14 cases and dehiscence in one). Residual or recurrent stenosis was seen in 7 arteries, whereas the anatomic result was satisfactory in 25 arteries (53%). Blood pressures returned to normal in 16 of 40 (40%) patients successfully treated by revascularization. An additional 25 patients recovered normal blood pressure values after primary nephrectomy (21), partial nephrectomy (4) or nephrectomy after failed renal revascularization.(ABSTRACT TRUNCATED AT 250 WORDS)
