Microsurgical Vasovasostomy versus Microsurgical Epididymal Sperm Aspiration/Testicular Extraction of Sperm Combined with Intracytoplasmic Sperm Injection

Purpose: Vasovasostomy (VVS) represents the standard therapy of choice for the treatment of obstructive azoospermia following vasectomy. However, recently, intracytoplasmic sperm injection (ICSI) has been suggested by some to represent the solution for all cases of malefactor infertility regardless of its etiology based on its success rates. Therefore, we compared VVS to microsurgical epididymal sperm aspiration (MESA)/testicular extraction of sperm (TESE) and ICSI in terms of pregnancy, complications, and costs.Patients and Methods: Between 1/93 and 6/98, 157 VVS were performed microsurgically using the double–layer technique. Between 9/94 and 9/97, 69 and 42 couples underwent MESA/ICSI and TESE/ICSI, respectively, for epididymal obstruction and azoospermia of testicular origin. Results: The mean interval of vasal obstruction was 7.6 (0.5–18) years; patency after VVS was 77%, pregnancy rate was 52%. Local complication rate was 4.7%, no major complications were observed. Costs per life birth after VVS were 5,447 DM or 2,793 Euro. Pregnancy rates after MESA/TESE and ICSI were 22.5 and 19.5%, respectively, with 16 singletons, 3 twins and 3 abortions; local complications occurred in 3.9% of the men. Multiple births were noticed in 15.8% following ICSI, but in only 0.7% following VVS. 5.7 and 1.4% of the female partners experienced serious complications (mild or severe ovarian hyperstimulation syndrome, respectively). Costs per life birth after a MESA/TESE cycle amounted to 28,804 DM or 14,547 Euro.Conclusions: Even in the era of ICSI, microsurgical VVS represents the standard approach for obstructive azoospermia following vasectomy. Based on a cost–benefit analysis, VVS is more successful in terms of pregnancy rates (52 vs. 22.5%). VVS does not expose the female partners to complications following treatment of male infertility. In contrast to ICSI, multiple birth rates do not increase after VVS. We conclude that MESA/ICSI should be reversed for patients who are not amenable for microsurgical reconstruction.
Dynamical localization of a thylakoid membrane binding protein is required for acquisition of photosynthetic competency

Vipp1 is highly conserved and essential for photosynthesis, but its function is unclear as it does not participate directly in light-dependent reactions. We analyzed Vipp1 localization in live cyanobacterial cells and show that Vipp1 is highly dynamic, continuously exchanging between a diffuse fraction that is uniformly distributed throughout the cell and a punctate fraction that is concentrated at high curvature regions of the thylakoid located at the cell periphery. Experimentally perturbing the spatial distribution of Vipp1 by relocalizing it to the nucleoid causes a severe growth defect during the transition from non-photosynthetic (dark) to photosynthetic (light) growth. However, the same perturbation of Vipp1 in dark alone or light alone growth conditions causes no growth or thylakoid morphology defects. We propose that the punctuated dynamics of Vipp1 at the cell periphery in regions of high thylakoid curvature enable acquisition of photosynthetic competency, perhaps by facilitating biogenesis of photosynthetic complexes involved in light-dependent reactions of photosynthesis.
Emotional mimicry of older adults’ expressions: effects of partial inclusion in a Cyberball paradigm

ABSTRACT As intergenerational interactions increase due to an ageing population, the study of emotion-related responses to the elderly is increasingly relevant. Previous research found mixed results regarding affective mimicry – a measure related to liking and affiliation. In the current study, we investigated emotional mimicry to younger and older actors following an encounter with a younger and older player in a Cyberball game. In a complete exclusion condition, in which both younger and older players excluded the participant, we expected emotional mimicry to be stronger for younger vs. older actors. In a partial inclusion condition, in which the younger player excluded while the older player included the participant, we predicted that the difference in player behaviour would lead to a difference in liking. This increased liking of the older interaction partner should reduce the difference in emotional mimicry towards the two different age groups. Results revealed more mimicry for older actors following partial inclusion especially for negative emotions, suggesting inclusive behaviour by an older person in an interaction as a possible means to increase mimicry and affiliation to the elderly.
Opportunities for Audiologists to Use Patient-Centered Communication during Hearing Device Monitoring Encounters

Abstract Patient-centered care incorporates patient's priorities, values, and goals. Audiologists can increase patient engagement when they use patient-centered principles during communication. Recent research, however, has revealed counseling gaps in audiology that could be detrimental to the intervention process. The present study sought to understand the extent patient-centered communication strategies were used during hearing device monitoring visits by analyzing audio recordings. Counseling portions of the appointments were transcribed using conversation analysis. Missed opportunities were observed, including not validating patients' emotional concerns, providing technical responses to emotional concerns, providing information without determining patient desire for the information, and not engaging the patient in a shared planning process. Training opportunities to enhance audiological services will be discussed.
Aircraft Measurements and Numerical Simulations of an Expansion Fan off the California Coast

AbstractMountains along the California coastline play a critical role in the dynamics of marine atmospheric boundary layer (MBL) airflow in the vicinity of the shoreline. Large changes in the MBL topology have been known to occur downwind of points and capes along the western coast of the United States. Large spatial gradients in wind and temperature become established that can cause anomalous electromagnetic wave propagation. Detailed airborne measurements using the University of Wyoming King Air were conducted to study the adjustment of the MBL to the Point Arguello and Point Conception headlands. Pronounced thinning of the MBL consistent with an expansion fan occurred to the south of Point Conception on 13 June 2012. A sharp cloud edge was collocated with the near collapse of the MBL. D-value cross sections derived from differential GPS altitude measurements allow assessment of the vertical profile of the horizontal pressure gradient force and hence thermal wind forcing in response to the near collapse.
Engineering water-tolerant core/shell upconversion nanoparticles for optical temperature sensing.

Luminescence thermometry is a promising approach using upconversion nanoparticles (UCNPs) with a nanoscale regime in biological tissues. UCNPs are superior to conventional fluorescent markers, benefiting from their autofluorescence suppression and deep imaging in tissues. However, they are still limited by poor water solubility and weak upconversion luminescence intensity, especially at a small particle size. Recently, YVO4:Er+3,Yb+3 nanoparticles have shown high efficiency upconversion (UC) luminescence in water at single-particle level and high contrast imaging in biological models. Typically, a 980-nm laser triggers the UC process in the UCNPs, which overlaps with maximum absorption of water molecules that are dominant in biological samples, resulting in biological tissues overheating and possible damaging. Interestingly, neodymium (Nd+3) possesses a large absorption cross section at the water low absorption band (808 nm), which can overcome overheating issues. In this Letter, we introduce Nd+3 as a new near-infrared absorber and UC sensitizer into YVO4:Er+3,Yb+3 nanoparticles in a core/shell structure to ensure successive energy transfer between the new UC sensitizer (Nd+3) to the upconverting activator (Er+3). Finally, we synthesized water-tolerant YVO4:Er+3,Yb+3@Nd+3 core/shell nanoparticles (average size 20 nm) with strong UC luminescence at a biocompatible excitation wavelength for optical temperature sensing where overheating in water is minimized.
Diagnostic overview of the illegal trade in primates and law enforcement in Peru

Peru has one of the richest primate faunas of any country. The illegal trade in wild primates is one of the largest threats to this fauna in Peru. We characterize the illegal trade in primates through empirical and ethnographic data. We collected data from traffic routes and centers throughout Peru and evaluate current efforts to combat this traffic. Based on our findings from 2,070 instances of wildlife crime involving 6,872 primates, we estimate the domestic trade in primates for pets and bushmeat in Peru in the hundreds of thousands per year, with the larger bodied Atelidae facing the highest direct consequences. We found that government authorities lack sufficient staff, capacity, resources, infrastructure, and protocols to efficiently combat illegal trade in primates. Also, the complicated legal framework and lack of cooperation and antagonism with the public further limit these efforts. Wildlife authorities in Peru are able to confiscate only a fraction of primates traded and mostly intervene in cases of private pet owners rather than traffickers. We estimate that the current rate of illegal trade in primates is comparable to levels of trade prior to the 1973 ban on primates’ exportation. The combination of direct observations on primate trade and ethnographic data allows a comprehensive look at primate trade in Peru. We call upon decision makers and international funders to channel their efforts toward “on the ground” actions such as increasing the ability of the authorities to act, giving them “in action” training in law enforcement and establishing strict control measures against corruption.

The Safety and Efficacy of Treatment with Nab-paclitaxel and Carboplatin for Patients with Advanced Squamous Non-small Cell Lung Cancer Concurrent with Idiopathic Interstitial Pneumonias

Objective Although lung squamous cell carcinoma (SCC) accounts for 20-30% of lung cancer cases, new treatment options are limited. The CA031 study showed that nanoparticle albumin-bound-paclitaxel (nab-PTX) plus carboplatin produced a significantly higher overall response rate (41%) than solvent-based paclitaxel plus carboplatin in patients with lung SCC. However, the safety and efficacy of combination chemotherapy of nab-PTX and carboplatin has not yet been established for patients with concurrent lung SCC and idiopathic interstitial pneumonias (IIPs). The aim of this study was to assess the safety and efficacy profiles of nab-PTX and carboplatin in patients with lung SCC and concurrent IIPs. Methods Eight patients with inoperable-stage lung SCC and IIPs were treated with nab-PTX plus carboplatin in a first-line setting between June 2013 and December 2016. One of the eight was a woman, and the median age was 77 (range=72-80) years. Their clinical outcomes, including chemotherapy-associated acute exacerbation of IIPs, were retrospectively investigated. Results The overall response rate was 50%, the median progression-free survival time was 5.6 months, and the median overall survival time was 8.1 months. No patients experienced chemotherapy-related exacerbation of IIPs in the first-line treatment with nab-PTX plus carboplatin. However, IIPs worsened in two of four patients who received second-line chemotherapy. Conclusion Combination chemotherapy of nab-PTX and carboplatin may be an effective and safe treatment option for patients with inoperable lung SCC with IIPs. To confirm this, a large-scale prospective study is needed.
Sex-specific Relationship of Serum Uric Acid with All-cause Mortality in Adults with Normal Kidney Function: An Observational Study

Objective. To explain the clinical effect of serum uric acid (SUA) levels as a risk factor for mortality, considering exclusion of kidney function. Methods. Participants aged over 40 years who underwent health checkups were recruited. Individuals with estimated glomerular filtrations rates < 60 ml/min/1.73 m2 and who received laboratory study and colonoscopy on the same day were excluded. Results. SUA levels were higher in men than in women (5.7 ± 1.2 mg/dl for men and 4.2 ± 0.9 mg/dl for women, p < 0.001). During 12.3 ± 3.6 years of followup, 1402 deaths occurred among 27,490 participants. About 6.9% of men and 3.1% of women died. The overall mortality rate had a U-shaped association with SUA levels, a U-shaped association in men, and no association in women. There was a significant interaction of sex for the SUA-mortality association (p for interaction = 0.049); therefore, survival analysis was conducted by sex. In men, the lower SUA group had a higher mortality rate after adjustment (SUA ≤ 4.0 mg/dl, adjusted HR 1.413, 95% CI 1.158–1.724, p = 0.001) compared with the reference group (SUA 4.1–6.0 mg/dl). A higher SUA contributed to an insignificant increased mortality in men (> 8.0 mg/dl, adjusted HR 1.140, 95% CI 0.794–1.636, p = 0.479). Women failed to show any significant association between SUA and mortality. Conclusion. This study provided novel evidence that SUA-mortality association differed by sex. We demonstrated that a lower SUA was an independent risk factor for all-cause mortality in men with normal kidney function.
Clinical Orofacial Examination in Juvenile Idiopathic Arthritis: International Consensus-based Recommendations for Monitoring Patients in Clinical Practice and Research Studies

Objective. To develop international consensus-based recommendations for the orofacial examination of patients with juvenile idiopathic arthritis (JIA), for use in clinical practice and research. Methods. Using a sequential phased approach, a multidisciplinary task force developed and evaluated a set of recommendations for the orofacial examination of patients with JIA. Phase 1: A Delphi survey was conducted among 40 expert physicians and dentists with the aim of identifying and ranking the importance of items for inclusion. Phase 2: The task force developed consensus about the domains and items to be included in the recommendations. Phase 3: A systematic literature review was performed to assess the evidence supporting the consensus-based recommendations. Phase 4: An independent group of orofacial and JIA experts were invited to assess the content validity of the task force’s recommendations. Results. Five recommendations were developed to assess the following 5 domains: medical history, orofacial symptoms, muscle and temporomandibular joint function, orofacial function, and dentofacial growth. After application of data search criteria, 56 articles were included in the systematic review. The level of evidence for the 5 recommendations was derived primarily from descriptive studies, such as cross-sectional and case-control studies. Conclusion. Five recommendations are proposed for the orofacial examination of patients with JIA to improve the clinical practice and aid standardized data collection for future studies. The task force has formulated a future research program based on the proposed recommendations.
Efficacy and safety of a novel high-dose mesalazine tablet in mild to moderate active ulcerative colitis: a double-blind, multicentre, randomised trial

Background Adherence to mesalazine treatment is essential for the successful treatment of ulcerative colitis. Objective The objective of this study was to compare the efficacy, safety and preference of a novel high-dose 1000 mg mesalazine tablet versus conventional treatment for ulcerative colitis remission. Methods This pivotal phase III trial compared one 1000 mg mesalazine tablet (M1000 group) versus two registered 500 mg mesalazine tablets (M2x500 group), both taken three times daily, in patients with mild to moderately active ulcerative colitis. The primary efficacy variable was clinical remission at week 8. Results A total of 306 patients were considered for intent-to-treat analysis. Clinical remission was achieved in 45.0% of the patients in the M1000 group versus 41.9% in the M2x500 group (P < 0.001 for non-inferiority). Mucosal healing was achieved by 68.9% of the patients in the M1000 group and 68.4% in the M2x500 group. The majority of patients preferred the intake of one high-dose tablet (47.7%) over two low-dose tablets (10.5%). Oral treatment with high-dose 1000 mg mesalazine tablets was well tolerated without new safety signals. Conclusions The novel high-dose 1000 mg mesalazine tablet is effective, non-inferior to the registered 500 mg mesalazine tablet, and safe for ulcerative colitis treatment. It was preferred by a majority of patients and may improve ulcerative colitis treatment adherence.
Shape disparity of bovid (Mammalia, Artiodactyla) horn sheaths and horn cores allows discrimination by species in 3D geometric morphometric analyses

The bony cranial structures of even‐toed hoofed mammals are important for understanding ecology and behavior of ruminants. Horns, the cranial appendages of the family Bovidae, are covered in a layer of keratin that is often not preserved in the fossil record; however, this keratin sheath is intimately involved in the processes that influence horn shape evolution. To understand the relationship between these two components of horns, we quantified both core and sheath shape for four extant species using three‐dimensional geometric morphometric analyses in separate, core‐ and sheath‐specific morphospaces as well as a combined morphospace. We assessed correlations between the horn and sheath morphospaces using two‐block partial least squares regression, a Mantel test of pairwise distances between species, and Procrustes ANOVA. We measured disparity in the combined morphospace as Procrustes distances between mean shapes of cores and sheaths within and between species and as Procrustes variance. We also tested whether core and sheath shapes could be discriminated by taxon with a canonical variate analysis. Results show that horn core and sheath morphospaces are strongly correlated. The differences in shape between a species' core and sheath were statistically significant, but not as great as those between the cores and sheaths of different species when close relatives were not considered, and core and sheath Procrustes variances are not significantly different within species. Cores and sheath shapes were highly identifiable and were assigned to the correct clade 93% of the time in the canonical variate analysis. Based on these tests, horn cores are distinguishable in geometric morphometric analyses, extending the possibility of using geometric morphometrics to study the ecology and evolution of bovid horns to the fossil record.
Waitlist Outcomes for Patients Relisted Following Failed Donation After Cardiac Death Liver Transplant: Implications for Awarding Model for End‐Stage Liver Disease Exception Scores

Understanding of outcomes for patients relisted for ischemic cholangiopathy following a donation after cardiac death (DCD) liver transplant (LT) will help standardization of a Model for End‐Stage Liver Disease exception scheme for retransplantation. Early relisting (E‐RL) for DCD graft failure caused by primary nonfunction (PNF) or hepatic artery thrombosis (HAT) was defined as relisting ≤14 days after DCD LT, and late relisting (L‐RL) due to biliary complications was defined as relisting 14 days to 3 years after DCD LT. Of 3908 DCD LTs performed nationally between 2002 and 2016, 540 (13.8%) patients were relisted within 3 years of transplant (168 [4.3%] in the E‐RL group, 372 [9.5%] in the L‐RL group). The E‐RL and L‐RL groups had waitlist mortality rates of 15.4% and 10.5%, respectively, at 3 mo and 16.1% and 14.3%, respectively, at 1 year. Waitlist mortality in the L‐RL group was higher than mortality and delisted rates for patients with exception points for both hepatocellular carcinoma (HCC) and hepatopulmonary syndrome (HPS) at 3‐ to 12‐mo time points (p < 0.001). Waitlist outcomes differed in patients with early DCD graft failure caused by PNF or HAT compared with those with late DCD graft failure attributed to biliary complications. In L‐RL, higher rates of waitlist mortality were noted compared with patients listed with exception points for HCC or HPS.
Toxoplasma gondii: Laboratory Maintenance and Growth

Toxoplasma gondii is a highly successful apicomplexan protozoan capable of infecting any warm‐blooded animal worldwide. In humans, Toxoplasma infections are life‐long, with approximately one‐third of the world's population chronically infected. Although normally controlled by the host immune system, T. gondii infection can lead to a variety of clinical outcomes in individuals with immature or suppressed immune systems. After penetrating the intestine, parasites rapidly disseminate throughout the body and stimulate production of the cytokines interleukin (IL)‐12, IL‐18, and interferon (IFN)‐γ by immune cells. These cytokines play a key role in host resistance to T. gondii by promoting a strong Th1 response. Recent reports show that gut commensal bacteria can act as molecular adjuvants during T. gondii infection. Thus, T. gondii is an excellent model system to study host‐pathogen interactions. This unit outlines the protocols for in vitro and in vivo maintenance and growth of T. gondii. © 2017 by John Wiley & Sons, Inc.
Switched-Capacitor-Based Dual-Switch High-Boost DC–DC Converter

A switched-capacitor-based dual-switch dc–dc converter with a high-boost voltage gain is proposed in this paper. The proposed converter can obtain a high-voltage gain with a small duty cycle, which decreases the voltage stress and the conduction loss on the power switches. This paper presents the key waveforms, the operating principles at the continuous conduction mode and the discontinuous conduction mode, and the parameter design. Moreover, a comparison between the proposed converter and other nonisolated converters has been completed. To verify the operating principle, a 200 W prototype is constructed with an input voltage of 25–50 V and an output voltage of 200 V. The simulation and experimental results are shown.
An Interventional Study Using Cell‐Mediated Immunity to Personalize Therapy for Cytomegalovirus Infection After Transplantation

Cell‐mediated immune responses predict clinical cytomegalovirus (CMV) events but have not been adopted into routine practice due to lack of interventional studies. Our objective was to demonstrate the safety and feasibility of early discontinuation of antivirals based on the real‐time measurement of CMV‐specific cell‐mediated immunity (CMI) in patients with CMV viremia. Transplant patients were enrolled at the onset of CMV viremia requiring antiviral therapy. CD8 T cell responses were determined using the Quantiferon‐CMV assay, and results were used to guide subsequent management. A total of 27 patients (median viral load at onset 10 900 International Units/mL) were treated until viral load negative. At end of treatment, 14/27 (51.9%) had a positive CMV‐CMI response and had antivirals discontinued. The remaining 13/27 (48.1%) patients had a negative CMV‐CMI response and received 2 months of secondary antiviral prophylaxis. In those with a positive CMI and early discontinuation of antivirals, only a single patient experienced a low‐level asymptomatic recurrence. In contrast, recurrence was observed in 69.2% of CMI‐negative patients despite more prolonged antivirals (p = 0.001). In conclusion, this is the first study to demonstrate the feasibility and safety of real‐time CMV‐specific CMI assessment to guide changes to the management of CMV infection.
