Published: July 2018

Autonomic control of blood pressure (BP) and heart rate (HR) is crucial during bleeding and hemorrhagic shock (HS) to compensate for hypotension and hypoxia. Previous works have observed that at the point of hemodynamic decompensation a marked suppression of BP and HR variability occurs, leading to irreversible shock. We hypothesized that recovery of the autonomic control may be decisive for effective resuscitation, along with restoration of mean BP. We computed cardiovascular indexes of baroreflex sensitivity and BP and HR variability by analyzing hemodynamic recordings collected from five pigs during a protocol of severe hemorrhage and resuscitation; three pigs were sham-treated controls. Moreover, we assessed the effects of severe hemorrhage on heart functionality by integrating the hemodynamic findings with measures of plasma high-sensitivity cardiac troponin T and metabolite concentrations in left ventricular (LV) tissue. Resuscitation was performed with fluids and norepinephrine and then by reinfusion of shed blood. After first resuscitation, mean BP reached the target value, but cardiovascular indexes were not fully restored, hinting at a partial recovery of the autonomic mechanisms. Moreover, cardiac troponins were still elevated, suggesting a persistent myocardial sufferance. After blood reinfusion all the indexes returned to baseline. In the harvested heart, LV metabolic profile confirmed the acute stress condition sensed by the cardiomyocytes. Variability indexes and baroreflex trends can be valuable tools to evaluate the severity of HS, and they may represent a more useful end point for resuscitation in combination with standard measures such as mean values and biological measures. NEW & NOTEWORTHY Autonomic control of blood pressure was highly impaired during hemorrhagic shock, and it was not completely recovered after resuscitation despite global restoration of mean pressures. Moreover, a persistent myocardial sufferance emerged from measured cardiac troponin T and metabolite concentrations of left ventricular tissue. We highlight the importance of combining global mean values and biological markers with measures of variability and autonomic control for a better characterization of the effectiveness of the resuscitation strategy.

AbstractThe aims of this study were to establish whether the sex-determining region Y gene and its mRNA transcript are present in the Y sperm and X sperm of bulls and, if present, determine their cellular localization. Semen was collected from three bulls and sorted by flow cytometry into X- and Y-chromosome populations. Reverse transcription-polymerase chain reaction (RT-PCR) was used to determineSrymRNA expression in X sperm and Y sperm. The presence and localization ofSryDNA and RNA were investigated by fluorescence in situ hybridization (FISH). RT-PCR detected a singleSrytranscript of 142 bp in Y sperm but not in X sperm. In Y sperm, the FISH-positive rates forSryDNA andSryRNA did not differ significantly from the re-analyzed Y sperm purity. In further experiments, there were no significant differences between the FISH-positive rate forSryRNA and the re-analyzed Y sperm purity for X-sorted, Y-sorted, or unsorted sperm. In conclusion, FISH analysis revealed thatSrytranscripts are present at the edges of the sperm heads of Y sperm but are absent from X sperm.

AbstractInformation about mating status can be used to decide about whether to invest resources in mating with a particular partner. In the present study, we evaluated mate choice in relation to the mating experience of males and females ofMenochilus sexmaculatus. We subjected both unmated and multiply mated males and females to different mate choice trials. The mating experience of the adults includes unmated, once-mated, twice-mated and multiply mated. The mate choice trials revealed that unmated adults were preferred over mated adults by both unmated and multiply mated partners. This preference for unmated partners also had consequences for mating behaviour and reproductive output. Unmated and multiply mated females commenced mating with unmated males earlier. In addition, unmated and multiply mated males invested more time in copula with unmated females. Moreover, females mated with unmated males were more fecund than those mated with previously mated males. This suggests that mating experience of mates may influence mating and reproductive behaviour in this species.

Published: July 2018

Objective Carcinosarcoma consists of carcinomatous and sarcomatous tissues and is an aggressive malignant tumor. It is rarely reported in the hypopharynx. Methods A 72-year-old man presented with dysphagia and dyspnea. Laryngoscopy, computed tomography (CT), and 18F-fluorodeoxyglucose positron emission tomography/CT (18F-FDG PET/CT) showed a neoplasm on the left posterior hypopharyngeal wall. The patient underwent bilateral neck dissection and excision of the hypopharyngeal cancer followed by postoperative radiation therapy. Results Immunohistochemistry revealed carcinomatous cells with membrane positivity for cytokeratin, glucose transporter-1 (GLUT-1), phosphoinositide-3 kinase (PI3K), hypoxia-inducible factor-1α (HIF-1α), and hexokinase-II as well as sarcomatous cells with membrane positivity for smooth muscle actin, GLUT-1, HIF-1α, and PI3K. Histopathology and immunohistochemistry revealed a true carcinosarcoma of the hypopharynx (pT3N0M0, Stage III). Conclusions Thorough immunohistochemistry is required for a correct diagnosis of hypopharyngeal carcinosarcoma. 18F-FDG PET/CT may help to distinguish hypopharyngeal carcinosarcoma from benign tumors.

Objective This study was performed to identify risk factors for acute cellular rejection after liver transplantation (LT). Methods Consecutive LT recipients who underwent surgery in our institution from 2002 to 2015 were retrospectively evaluated. Results In total, 176 patients were eligible for statistical analysis. During a mean observation period of 61.1 ± 36.3 months, 43 episodes of acute rejection were evident. Of these, 34 (79.0%) were responsive to methylprednisolone, 3 (7.0%) were treated by adjusting the dosage of immunosuppressive agents, and 6 (14.0%) were methylprednisolone-resistant and treated using anti-thymocyte globulin. Biliary complications (odds ratio [OR] = 4.89, 95% confidence interval [CI] = 2.00–11.98); donor-negative, recipient-positive CMV mismatch (OR = 9.88, 95% CI = 1.18–82.36); sex mismatch (OR = 3.16, 95% CI = 1.31–8.10); and sex mismatch with a female donor (OR = 3.00, 95% CI = 1.10–7.58) were identified as significant risk factors for acute graft rejection after LT. Conclusion In patients who develop acute cellular rejection after LT, biliary complications should be evaluated as a potential cause. Most acute rejections after LT respond to bolus corticosteroid therapy.
Evidence-Based Best-Practice Guidelines for Preventing Anterior Cruciate Ligament Injuries in Young Female Athletes: A Systematic Review and Meta-analysis
Authors: Petushek Erich J. , Sugimoto Dai , Stoolmiller Michael , Smith Grace , Myer Gregory D. 
Published: July 2018

Background: Injury prevention neuromuscular training (NMT) programs reduce the risk for anterior cruciate ligament (ACL) injury. However, variation in program characteristics limits the potential to delineate the most effective practices to optimize injury risk reduction. Purpose: To evaluate the common and effective components included in ACL NMT programs and develop an efficient, user-friendly tool to assess the quality of ACL NMT programs. Study Design: Systematic review and meta-analysis. Methods: Study inclusion required (1) a prospective controlled trial study design, (2) an NMT intervention aimed to reduce incidence of ACL injury, (3) a comparison group, (4) ACL injury incidence, and (5) female participants. The following data were extracted: year of publication, study design, sample size and characteristics, and NMT characteristics including exercise type and number per session, volume, duration, training time, and implementer training. Analysis entailed both univariate subgroup and meta-regression techniques using random-effects models. Results: Eighteen studies were included in the meta-analyses, with a total of 27,231 participants, 347 sustaining an ACL injury. NMT reduced the risk for ACL injury from 1 in 54 to 1 in 111 (odds ratio [OR], 0.51; 95% CI, 0.37-0.69]). The overall mean training volume was 18.17 hours for the entire NMT (24.1 minutes per session, 2.51 times per week). Interventions targeting middle school or high school–aged athletes reduced injury risk (OR, 0.38; 95% CI, 0.24-0.60) to a greater degree than did interventions for college- or professional-aged athletes (OR, 0.65; 95% CI, 0.48-0.89). All interventions included some form of implementer training. Increased landing stabilization and lower body strength exercises during each session improved prophylactic benefits. A meta-regression model and simple checklist based on the aforementioned effective components (slope = −0.15, P = .0008; intercept = 0.04, P = .51) were developed to allow practitioners to evaluate the potential efficacy of their ACL NMT and optimize injury prevention effects. Conclusion: Considering the aggregated evidence, we recommend that ACL NMT programs target younger athletes and use trained implementers who incorporate lower body strength exercises (ie, Nordic hamstrings, lunges, and heel-calf raises) with a specific focus on landing stabilization (jump/hop and hold) throughout their sport seasons. Clinical Relevance: Clinicians, coaches, athletes, parents, and practitioners can use the developed checklist to gain insight into the quality of their current ACL NMT practices and can use the tool to optimize programming for future ACL NMT to reduce ACL injury risk.

Objective: To investigate whether radial artery pressure is a reliable surrogate measure of central arterial pressure as approximated by femoral artery pressure in minimally invasive cardiac surgery with retrograde perfusion via femoral cannulation. Method: Fifty-two consecutive patients undergoing minimally invasive cardiac surgery were prospectively included in this study. Cardiopulmonary bypass was established via a femoral artery cannulation and femoral vein. Radial and femoral arterial pressures were recorded continuously, and the pressure differential between them was calculated for both systolic and mean arterial pressures. The agreement between measurements from the two arteries was compared using Bland–Altman plots. An interval of 95% limits of agreement of less than 20 mm Hg was set as satisfactory agreement. Results: Average age was 65 ± 14 years. With respect to systolic arterial pressure, 28 patients (54%) had a peak pressure differential between radial and femoral arteries ⩾20 mm Hg. With respect to mean arterial pressure, only five patients (9%) had a peak pressure differential ⩾20 mm Hg. The pressure differential changed with time. Pressure differential in systolic arterial pressure was 5 ± 8 mm Hg until aortic declamping, then increased to a peak of 23 ± 16 mm Hg when cardiopulmonary bypass was turned off. The femoral systolic arterial pressures were significantly greater than radial systolic arterial pressures from time of aortic declamping to 20 min after cardiopulmonary bypass. The Bland–Altman plots revealed large biases and poor agreement in this period. Conclusion: Radial and femoral systolic artery pressure readings can differ significantly in minimally invasive cardiac surgery with retrograde perfusion. Intraoperative arterial pressure management based solely on radial systolic arterial pressure readings should be avoided.

Purpose: To evaluate the effects of iDecide on prostate cancer knowledge, informed decision-making self-efficacy, technology use self-efficacy, and intention to engage in informed decision-making among African American men. Design: One-group, pretest/posttest. Setting: Community settings in South Carolina. Participants: African American men, ages 40 years +, without a prior prostate cancer diagnosis (n = 354). Intervention: iDecide, an embodied conversational agent-led, computer-based prostate cancer screening decision aid. Measures: Prostate cancer knowledge, informed decision-making self-efficacy, technology use self-efficacy, and intention to engage in informed decision-making. Analysis: Descriptive statistics, paired t tests, general linear modeling, Spearman correlations. Results: On average, participants experienced significant improvements in their prostate cancer knowledge ( P ≤ .001), informed decision-making self-efficacy ( P ≤ .001), and technology use self-efficacy ( P ≤ .001), postintervention. Additionally, 67% of participants reported an intention to engage in informed decision-making. Conclusion: Given the significant improvements across all measures, this research demonstrates that embodied conversational agent-led decision aids can be used to enhance the capacity for making informed prostate cancer screening decisions among African American men and increase their technology use self-efficacy. One critical limitation of this study is that most men had received prostate cancer screening prior to engaging in our intervention, so the implications of this intervention may be different for men who do not have a history of screening. Additionally, actual engagement in informed decision-making postintervention was not assessed.
Oskar Kobyliński (1856–1926) and the first description of Noonan syndrome in the medical literature
Authors: Marcinowski Filip 
Published: July 2018

While a student of University in Dorpat (now Tartu, Estonia) Oskar Kobyliński published an article reporting on his 22-year-old patient Leisar Eischikmann, who suffered from a congenital deformity of the neck. Kobyliński described this rare anomaly and called it “flüghautige Verbreitung des Halses” (wing-like extension of the neck). It was only in 1902 when the name pterygium colli was introduced, and it has been in use ever since. This malformation is part of some congenital syndromes, most prominently, Turner syndrome and, more rarely, of Noonan syndrome. As Opitz et al. pointed out, the patient described in the 1883 article from Archiv für Anthropologie is probably the first person with Noonan syndrome to have been pictured in the medical literature. The article was signed only by “O. v. Kobylinski, student of medicine.” Further archival research was needed to identify this physician and provide more details about his unusual career.
Environmental Fiscal Instruments: A Few International Experiences
Authors: Verma Rajat , Gayithri K. 
Published: July 2018

This article attempts to document the status of environmental fiscal instruments (EFIs) so as to explore relevant international experiences on ecotaxes in the context of India and to examine India’s specificities in these taxes within a wider perspective of other fiscal measures. Environmental levies across 15 countries were reviewed and the countries categorised are into two groups: Annex II and Non-Annex I. The revenues from levies imposed in the countries were also analysed. The most common form of taxes in Annex II countries in the form of energy taxes, followed by transport taxes. For India, energy and transport taxes could prove to be vital types of ecotaxes for addressing issues of climate change. Pollution taxes are difficult to levy for administrative reasons, but resource taxes are imperative because of severe environmental problems associated with mining and related activities. The revenue generated from environmental taxes and charges for all Annex II countries hovered between 2 and 4 per cent of their respective GDPs, except for Canada and the United States of America, whereas for Non-Annex I nations, this ranged only between 0 and 1 per cent.

Slowdown in Bank Credit Growth: Aggregate Demand or Bank Non-performing Assets?
Authors: Goyal Ashima , Verma Akhilesh 
Published: July 2018

We estimate the determinants of credit and of non-performing assets (NPAs) using a firm and a bank panel with data up to 2015 in order to test bank lending against the aggregate demand channel as an explanation for slow Indian credit growth. The results support demand as the key constraint. Only demand variables affect corporate credit for a broad set of firms. Balance sheet weakness reduced credit only for a narrow subset of indebted firms in a difference-in-difference type analysis. Even so, sales remained the dominant variable. From the bank panel, the asset quality review (AQR) did have a strong negative effect on advances but gross NPAs did not. While high interest rates and low growth raised NPAs, so did past credit. Low demand not only reduced credit, it also increased NPAs. That the capital adequacy ratio (CAR) significantly reduces NPAs points to the productivity of fund infusion. When other determinants are controlled, bank ownership does not affect NPA ratios, again supporting external shocks as causal. The results suggest that apart from structural reform to clean balance sheets, recovery of demand is necessary for revival of credit growth. JEL Classification: G21, E51

Authors: Zhang Yi , Fan Yu , Fan Jinlu , Cui Yanhui 
Published: July 2018

Purpose: To evaluate the surgical intervention and its effect on congenital dacryocystocele. Methods: A total of 531 children with congenital dacryocystocele admitted to the Department of Ophthalmology of Beijing Children’s Hospital, Shanghai Aier Eye Hospital, Nanjing Aier Eye Hospital, and the First Affiliated Hospital of Jinzhou Medical University between January 2007 and January 2017 were retrospectively analyzed. Results: A total of 531 patients were followed up for 3–24 months, with an average of 13.3 months. No serious intraoperative complications (such as bleeding and tissue damage) and postoperative complications (bleeding, infection, and hole atresia) were found. We classified the outcomes into three categories based on the signs (overflowing tears and empyema) and objective routine follow-up by endoscopy. Cure indicated that mass, overflow of tears, and breathing difficulties disappeared, and 81.5% cases (433/531) were postoperatively cured. Improvement indicated disappearance of mass, overflow empyema, and the presence of residual tears (due to trocar and tears puncture), and 18.5% cases (98/531) were postoperatively improved. Unhealed indicated overflowing pus and tears, and 0% cases did not heal after surgery. Conclusions: Nasal endoscopic surgery is relatively safe, with high success rate for treatment of congenital dacryocystocele. Systematic training is required to promote the application of nasal endoscopy, so that more ophthalmologists can learn this technique.

Published: July 2018

Purpose: We aimed to analyze the visual prognosis and clinical characteristics of acute retinal necrosis according to the initially involved zone and extent. Study design: Retrospective, consecutive, cross-sectional study. Methods: We retrospectively reviewed acute retinal necrosis patients who were treated with systemic antiviral treatment, and assessed the visual prognosis of acute retinal necrosis following antiviral treatment based on the initially involved zone and the extent of acute retinal necrosis at the time of diagnosis. Moreover, we evaluated whether prophylactic laser photocoagulation had preventive effects on retinal detachment. Results: A total of 43 eyes from 35 patients with acute retinal necrosis were included. Eyes with zone I involvement/extensive retinal lesions showed poor visual prognosis (logMAR: 1.17 ± 0.97 vs 0.49 ± 0.81; p = 0.014) and a higher incidence of retinal detachment (9/30 (30.0%) vs 0/13 (0%); p = 0.039) after treatment. Retinal detachment was observed in 20.9% of cases, and its incidence was significantly lower in eyes that had undergone prophylactic laser photocoagulation. Conclusion: The overall visual prognosis of acute retinal necrosis is poor and can be determined at the time of diagnosis. Prophylactic laser photocoagulation exhibits preventive effects with regard to the development of retinal detachment. Therefore, laser photocoagulation should be actively considered in eyes with extensive retinal lesions to prevent retinal detachment and thus eventually improve the overall visual prognosis of acute retinal necrosis.
Acute Hereditary Angioedema With Airway Compromise: Avoiding Airway Intervention With C1 Inhibitor Concentrate
Authors: Fu WeiZhong Ernest , Tan Sze-Chin , Ho Eu Chin 
Published: July 2018

Introduction: Hereditary angioedema (HAE) is an autosomal dominant disease caused by deficiency of the plasma protein C1 inhibitor (C1-INH). Patients classically present with recurrent localized subcutaneous or submucosal edema lasting for 2 to 5 days, severe abdominal pain, or acute airway obstruction which can be fatal. Case presentations: We highlight 2 patients with acute airway compromise secondary to HAE who were successfully treated with plasma-derived C1-INH concentrates. Conclusions: The timely administration of plasma-derived C1-INH concentrates for the acute treatment of HAE has been proven to be effective in both patients in aborting an airway complication. A high index of suspicion is required for the early diagnosis and treatment of this potentially fatal condition.
