Hypertension during pregnancy and preeclampsia are associated with increased arterial thrombotic risk in later life. Whether these complications are associated with risk of venous thromboembolism (VTE) on the short term after pregnancy and on the long term, that is, outside pregnancy, is largely unknown. We conducted a nationwide cohort study in women with at least 1 pregnancy and their first VTE risk by linking the Dutch perinatal registry (Perined) to anticoagulation clinics. We used Cox proportional hazard models to estimate hazard ratios (HRs) and corresponding 95% CI for VTE risk in women with hypertension during pregnancy, women with preeclampsia, compared with women with uncomplicated pregnancies (reference). A total of 1 919 918 women were followed for a median of 13.7 (interquartile range, 7.6–19.2) years for a total of 24 531 118 person-years in which 5759 first VTEs occurred; incidence rate: 2.3 (95% CI, 2.3–2.4) per 10 000 person-years. In the first pregnancy and 3-month postpartum period, VTE risk was higher in women with hypertension, HR, 2.0 (95% CI, 1.7–2.4), and highest among women with preeclampsia, HR, 7.8 (95% CI, 5.4–11.3), versus the reference group. On the long term, women with hypertension during pregnancy and preeclampsia had a higher VTE risk: HR, 1.5 (95% CI, 1.4–1.6) and HR, 2.1 (95% CI, 1.8–2.4), respectively, versus the reference group. When excluding events during pregnancy and postpartum, these HRs were 1.4 (95% CI, 1.3–1.5) and 1.6 (95% CI, 1.4–2.0), respectively. In conclusion, hypertension during pregnancy and preeclampsia are associated with an increased VTE risk during pregnancy and postpartum period and in the 13 years after.

The great diversity of the genus Mimosa and the difficulty in the circumscription of its species and varieties based on morphology have encouraged the search for characters in other sources of evidence such as wood anatomy, which provides characters of taxonomic importance. The main objective of this study was to identify characters with taxonomic value for Mimosa; we studied the wood anatomy of eight tree species in Mimosa sect. Batocaulon from Mexico: Mimosa acantholoba, M. bahamensis, M. benthamii, M. hexandra, M. leucaenoides, M. tejupilcana, M. tenuiflora, and M. texana belonging to eight series: Acantholobae, Bahamenses, Distachyae, Bimucronatae, Leucaenoideae, Plurijugae, Leiocarpae and Boreales, respectively. One stem fragment (80 cm in length) was collected at 80 cm above soil height, from three plants per species. Twenty-five measurements were taken per individual for 15 anatomical characters. Three species have ring-porous wood and five species have diffuse-porous wood; the species differ in colour, figure, in the prevalence of a certain type of axial parenchyma, in the tangential diameter of the earlywood vessels, in the number of vessels connected by confluent-aliform parenchyma, in the number of series of rays and in the presence or absence of crystal sand in the ray cells. These characters have taxonomic value at species level, but not at series level. At the section level, the presence of homocellular rays distinguished Batocaulon from other sections of the genus. Based on these results, we produced a wood anatomical identification key to the eight studied species.

Published: January 2020

A new species of Cymbidium (Orchidaceae), Cymbidium biflorens, from Yunnan Province, China, is illustrated and described based on morphological and molecular evidence. Morphological comparison indicates that C. biflorens is similar to C. rhizomatosum, but differs by its leafless, coralline rhizome, normally two flowering periods, a shorter scape, inflorescence with 1–2 flowers, greenish flowers with longer pedicel and ovary, subelliptic petal, petals and lip not fully opened. Molecular analyses base on nuclear (ITS) and plastid DNA (matK and rbcL) were conducted to explore the phylogenetic position of the species. The molecular evidence supports C. biflorens as sister to C. rhizomatosum.

Published: January 2020

Assessing change in daily maximum wind speed and its likely causes is crucial for many applications such as wind power generation and wind disaster risk governance. Multidecadal variability of observed near-surface daily maximum wind speed (DMWS) from 778 stations over China is analyzed for 1975–2016. A robust homogenization protocol using the R package Climatol was applied to the DMWS observations. The homogenized dataset displayed a significant (p < 0.05) declining trend of −0.038 m s−1 decade−1 for all China annually, with decreases in winter (−0.355 m s−1 decade−1, p < 0.05) and autumn (−0.108 m s−1 decade−1; p < 0.05) and increases in summer (+0.272 m s−1 decade−1, p < 0.05) along with a weak recovery in spring (+0.032 m s−1 decade−1; p > 0.10); that is, DMWS declined during the cold semester (October–March) and increased during the warm semester (April–September). Correlation analysis of the Arctic Oscillation, the Southern Oscillation, and the west Pacific modes exhibited significant correlation with DMWS variability, unveiling their complementarity in modulating DMWS. Further, we explored potential physical processes relating to the atmospheric circulation changes and their impacts on DMWS and found that 1) overall weakened horizontal airflow [large-scale mean horizontal pressure gradient (from −0.24 to +0.02 hPa decade−1) and geostrophic wind speed (from −0.6 to +0.6 m s−1 decade−1)], 2) widely decreased atmospheric vertical momentum transport [atmospheric stratification thermal instability (from −3 to +1.5 decade−1) and vertical wind shear (from −0.4 to +0.2 m s−1 decade−1)], and 3) decreased extratropical cyclones frequency (from −0.3 to 0 month decade−1) are likely causes of DMWS change.
Characteristics of Ice Cloud–Precipitation of Warm Season Mesoscale Convective Systems over the Great Plains
Authors: Tian Jingjing , Dong Xiquan , Xi Baike , Feng Zhe
Published: January 2020

In this study, the mesoscale convective systems (MCSs) are tracked using high-resolution radar and satellite observations over the U.S. Great Plains during April–August from 2010 to 2012. The spatiotemporal variability of MCS precipitation is then characterized using the Stage IV product. We found that the spatial variability and nocturnal peaks of MCS precipitation are primarily driven by the MCS occurrence rather than the precipitation intensity. The tracked MCSs are further classified into convective core (CC), stratiform rain (SR), and anvil clouds regions. The spatial variability and diurnal cycle of precipitation in the SR regions of MCSs are not as significant as those of MCS precipitation. In the SR regions, the high-resolution, long-term ice cloud microphysical properties [ice water content (IWC) and ice water paths (IWPs)] are provided. The IWCs generally decrease with height. Spatially, the IWC, IWP, and precipitation are all higher over the southern Great Plains than over the northern Great Plains. Seasonally, those ice and precipitation properties are all higher in summer than in spring. Comparing the peak timings of MCS precipitation and IWPs from the diurnal cycles and their composite evolutions, it is found that when using the peak timing of IWPSR as a reference, the heaviest precipitation in the MCS convective core occurs earlier, while the strongest SR precipitation occurs later. The shift of peak timings could be explained by the stratiform precipitation formation process. The IWP and precipitation relationships are different at MCS genesis, mature, and decay stages. The relationships and the transition processes from ice particles to precipitation also depend on the low-level humidity.

Published: January 2020

The impacts of diurnal atmospheric forcing on the summer salinity change in the East China Sea are investigated using the Regional Ocean Modeling System, forced by the hourly and daily reanalysis of wind and insolation. The differences between the forcing of these two frequencies reveal a dipole pattern of salinity change with a positive salinity deviation (1–2 psu) offshore of the Yangtze River estuary, and a negative deviation (from −1 to −0.5 psu) along the Jiangsu Coast. Further dye tracking experiments confirm that diurnal forcing strengthened the northwestward longshore freshwater transport (NLFT) of the Yangtze River by 5.2 × 109m3and reduced the mean water age of 7 days. Sensitivity experiments using different forcing combinations suggest that the diurnal wind, that is, the land–sea breeze, is the key to developing the dipole pattern of salinity change and the NLFT. Through the experiment, the land–sea breeze induced a mean clockwise circulation offshore of the Yangtze River estuary. The above changes resulted from both the nonlinearity of wind stress averaging (i.e., the square nature of wind stress) and the baroclinic adjustment related to the diurnal salinity variation, which is directly connected to the diurnal swing of the Yangtze River front. The baroclinic adjustment generated a dipole pattern of vorticity changes offshore of the Yangtze River estuary and a coherent northwestward jet current strengthening the NLFT. These processes developed the summer dipole pattern of the salinity change.
Dual Networking: How Collaborators Network in Their Quest for Innovation
Authors: Ter Wal Anne L. J. , Criscuolo Paola , McEvily Bill , Salter Ammon
Published: January 2020

Organizations typically employ a division of labor between specialist creator roles and generalist business roles in a bid to orchestrate innovation. We seek to determine the extent to which individuals dividing the work across roles can also benefit from dividing their network. We argue that collaborating individuals benefit from connecting to the same groups but different individuals within those groups—an approach we label dual networking—rather than from a pure divide-and-conquer approach. To test this argument, we study a dual career-ladder setting in a large multinational in which R&D managers and technologists partner up in their quest for innovation. We find that collaborators who engage in dual networking attain an innovation performance advantage over those who connect to distinct groups. This advantage stems from the opportunity to engage in the dual interpretation of input the partners receive, as well as from dual influencing that helps them to gain momentum for their proposed innovations, and it leads to more effective elaboration and championing of their ideas. In demonstrating these effects, we advance understanding of how collaborators organize their networking activities to best achieve innovative outcomes.
Temperature–Color Interaction: Subjective Indoor Environmental Perception and Physiological Responses in Virtual Reality
Authors: Chinazzo Giorgia , Chamilothori Kynthia , Wienold Jan , Andersen Marilyne
Published: January 2020

Objective

Temperature–color interaction effects on subjective perception and physiological responses are investigated using a novel hybrid experimental method combining thermal and visual stimuli from real and virtual reality (VR) environments, respectively.

Background

Despite potential building design applications, studies combining temperature with daylight transmitted through colored glazing are limited due to hard-to-control light conditions. VR is identified as a promising experimental tool for such investigations that overcomes the limitations of experiments using daylight.

Method

Fifty-seven people participated in an experiment combining three colored glazing (orange/blue/neutral) and two temperatures (24°C/29°C). Exposed to one color–temperature combination, participants evaluated their thermal, visual, and overall perception, whereas their physiological responses (heart rate, skin conductance, and skin temperature) were continuously measured.

Results

Daylight color significantly affected thermal perception, whereas no significant effects of temperature on visual perception were found. Acceptability of the workspace was affected by both color and temperature. Cross-modal effects from either daylight color or temperature levels on physiological responses were not observed.

Conclusion

In the VR setting, the orange daylight led to warmer thermal perception in (close-to-) comfortable temperatures, resulting in a color-induced thermal perception and indicating that orange glazing should be used with caution in a slightly warm environment.

Application

Findings can be applied to the design of buildings using new glazing technologies with saturated colors, such as transparent photovoltaics. Despite some limitations, the hybrid environment is suggested as a promising experimental tool for future studies on indoor factor interactions.

Published: January 2020

Introduction:

Cognitive impairment is one of the fundamental features among patients with schizophrenia. The relationship between schizophrenia symptoms, insight and cognitive domains remains controversial. We aimed to study these relations in a sample of Egyptian patients with schizophrenia.

Methods:

A total of 109 patients with schizophrenia were assessed using Structured Clinical Interview for DSM-IV ( Diagnostic and Statistical Manual of Mental Disorders (4th ed.)) Axis I diagnosis (SCID-I), Positive and Negative Syndrome Scale (PANSS) and Scale to Assess Unawareness of Medical Disorder (SUMD). Cognitive functions were assessed using the Wechsler Adult Intelligence Scale (WAIS), the Wisconsin Card Sorting Test (WCST) and the Wechsler Memory Scale (WMS). The cognitive functions would be distributed to cover six cognitive domains: attention/vigilance speed of processing, verbal learning, visual learning, working memory and reasoning/problem solving.

Results:

There was a significant correlation between all cognitive domains (except attention) and PANSS subscales. PANSS negative and general psychopathology subscales were significantly correlated with five cognitive domains: speed of processing, verbal learning, visual learning, working memory and reasoning/problem solving. PANSS negative subscale was significantly correlated with verbal learning (verbal paired association 1) and visual learning (visual paired association 1). There was a significant correlation between all cognitive domains and SUMD, except verbal and visual learning domains assessed by verbal and visual paired association 1 subtests, as well as attention assessed by failure to maintain set subtest. Only visual learning (trials administered), working memory (percentage error), and processing speed (perseverative responses, and trials to complete first category) were significantly negatively correlated to SUMD.

Conclusion:

Cognitive impairment in patients with schizophrenia is most likely to underlie negative symptoms, general psychopathology symptoms and poor insight, suggesting that treatment strategies minimizing these symptoms would improve cognitive impairment.
Microstructure and thermal properties of nickel-coated carbon fibers/aluminum composites
Authors: Yi Li-Fu , Yamamoto Takashi , Onda Tetsuhiko , Chen Zhong-Chun
Published: January 2020

Electroless nickel-coated carbon fibers/aluminum composites were prepared by spark plasma sintering, and the effect of nickel coating on microstructure and thermal properties of the composites has been investigated. Nickel coating on carbon fibers resulted in more homogeneous distributions of carbon fibers in aluminum matrix, higher relative density of carbon fibers/aluminum composites, and stronger interfacial bonding between carbon fibers and aluminum. Microstructural observations exhibited that the majority of carbon fibers were randomly distributed on the sections (X-Y direction) perpendicular to spark plasma sintering pressing direction (Z direction), thus leading to an anisotropic behavior in thermal conductivity of the composites. The thermal conductivity values in the X-Y direction of the carbon fibers/aluminum composites were much higher than those in the Z direction. As a result, the nickel-coated carbon fibers/aluminum composites with a nickel-coating thickness of ∼0.2 µm showed higher thermal conductivity and lower coefficient of thermal expansion values in comparison with those of the uncoated carbon fibers/aluminum samples.
Social Factors of Health-Seeking Behavior: On Medical Treatment for Elders With Dementia in Oaxaca, Mexico
Authors: Yahalom Jonathan
Published: January 2020

This article presents data on family caregiving for elders with dementia in Oaxaca, Mexico. Drawing on a year of ethnographic research, this article explores how caregivers engage in health-seeking behaviors and how they choose between biomedical and traditional medical alternatives. While caregivers are primarily concerned to maintain elders’ health, decisions about which medical providers to (not) consult invoke broader social factors that go beyond their relationships with elders, and concern socioeconomic realms of power, as well as broader ideals concerning local tradition and its maintenance in the contemporary world.
Influence of Lack of Trust on Romantic Relationship Problems: The Mediating Role of Partner Cell Phone Snooping
Authors: Arikewuyo Abdulgaffar O. , Eluwole Kayode K. , Özad Bahire
Published: January 2020

We investigated how a lack of trust in one’s romantic partner exacerbates problems such as emotional instability, conflict, or intention to break up in relationships with the role of cell phone snooping as a mediator. A cross-sectional survey of married individuals ( n = 329) was conducted using an online questionnaire. Results indicate that lack of trust is a significant predictor of romantic relationship problems. In addition, structural equation modeling results support the theoretical model indicating that cell phone snooping partially mediates the significant relationship between emotional instability, intention to break up, and conflicts. Findings support the development of trust in romantic partners as an approach to stability and avoidance of problems in romantic relationships.

Published: January 2020

A sense of belonging in a particular context is cued not only by the people in the role but by the affordances of the role—that is, the opportunities for goal pursuit. We investigate this role-based belonging in four studies documenting that the perceived affordances of social roles inform sense of belonging and convey known benefits of belonging. Perceiving more communal opportunities in naturalistic science, technology, engineering, and mathematic (STEM) settings was associated with heightened belonging in those roles (Studies 1–2). Experimentally manipulating collaborative activities in a science lab increased anticipated belonging in the lab and fostered interest, particularly among women (Study 3). Finally, mentally simulating communal affordances in a role promoted recovery from belonging threat: Considering communal opportunities in STEM facilitated recovery of STEM-specific belonging after recalling exclusion in STEM (Study 4). Investigations of role-based belonging offer the potential for both theoretical and practical advances.
The Lengthening Transition to Adulthood: Financial Parenting and Recentering during the College-to-Career Transition
Authors: Serido Joyce , LeBaron Ashley B. , Li Lijun , Parrott Emily , Shim Soyeon
Published: January 2020

Using longitudinal data collected from a college cohort in the United States ( N = 922), we examined the associations between systemic and structural factors (gender, race/ethnicity, family SES, and first-generation college status), financial parenting (teaching, and modeling behavior), and emerging adults’ financial behavior. We conducted a series of one-way repeated measure ANOVA analyses (GLM) to assess patterns of average change in financial parenting and financial behavior in the first year in college, fourth year in college, and two years after college and found evidence suggestive of recentering—a gradual transfer of responsibility during emerging adulthood from parent-directed behavior to self-directed behavior; however, the decline in financial parenting was not offset by an improvement in emerging adults’ financial behavior. Despite similar patterns of change, family socioeconomic status (SES), first-generation college student status, and gender influenced both financial parenting and financial behaviors at each time point. We discuss the findings and the implications on the timing and length of the recentering process.
The risk of lower-limb superficial vein thrombosis relative to lower-limb venous thrombotic events is not increased in winter months
Authors: Henni Samir , Ramondou Pierre , Duval Guillaume , Picquet Jean , Leftheriotis Georges , Abraham Pierre
Published: January 2020

Objectives

Ambient temperature (that impacts differently venous flow in superficial and deep veins) could have a different effect on the risk of superficial and deep venous thrombosis. We searched for a trimestral variation of the risk of superficial venous thrombosis among all lower-limb thrombotic events (lower-limb thrombotic events = superficial venous thrombosis + deep venous thrombosis).

Methods

We retrospectively analyzed the results of venous ultrasound investigations performed among 11,739 patients (aged 67 ± 19 years old, 56.1% males) referred for suspected lower-limb thrombotic events over a 12-year period. Chi-square test was used to compare the superficial venous thrombosis/lower-limb thrombotic events ratio observed by trimesters to a homogeneous distribution.

Results

The proportion of lower-limb thrombotic events were 30.7%, 28.8%, 31.1%, and 31.4% (Chi2: 0.133; p = 0.987) of total investigations, while that of superficial venous thrombosis among all lower-limb venous thrombotic events were 27.2%, 30.0%, 31.4%, and 31.0%, for the first, second, third, and fourth trimesters respectively (Chi2: 0.357; p: 0.949).

Conclusion

No trimestral variation of the superficial venous thrombosis/lower-limb venous thrombotic events ratio was observed.
Promoting Hispanic Immigrant Health via Community Health Workers and Motivational Interviewing
Authors: Portillo Erin M. , Vasquez Denise , Brown Louis D.
Published: January 2020

Hispanic immigrant health disparities are among the highest in the nation, especially related to obesity and access to health services. Healthy Fit (En Forma Saludable) is a health promotion program that leverages public health department infrastructure to address these disparities through the use of three key innovations explored in this article: community health workers (CHWs), motivational interviewing (MI), and vouchers for free preventative health services. CHWs trained in MI conduct a health screening and then distribute preventive service vouchers and health resources as needed based on screening results. Vouchers cover breast, cervical, and colorectal cancer screening, and several vaccinations including flu and human papillomavirus. Resources to support exercise, to support a healthy diet, to quit smoking, and to reduce risky drinking are also distributed as needed. CHWs then use MI to address perceived barriers and strengthen intrinsic motivation to make use of the health resources. Integrating these strategies provides a low-cost approach to promote healthy behavior in an underserved immigrant population.
How urban stormwater regimes drive geomorphic degradation of receiving streams
Authors: Russell Kathryn L , Vietz Geoff J , Fletcher Tim D
Published: January 2020

For streams draining urban catchments, sediment transport capacity is the key driver of physical impacts including bed sediment removal and channel incision. The main unanswered question is the relative role of flow alteration compared to sediment supply in influencing sediment transport capacity. With this objective, we computed sand and gravel bed sediment transport capacity using the Wilcock and Kenworthy two-fraction bedload transport relation for nine streams in catchments covering a gradient of urbanisation. Computations were done for typical natural bed surface material, based on conditions in the least urban study streams. We compared transport capacity distributions and cumulative transport capacity over one-year between the streams. Transport capacity was up to three orders of magnitude higher in urban streams than in forested-catchment streams. This was driven overwhelmingly by the urbanisation-induced alterations to the flow regime, with only minor feedback from channel form changes. Transport capacity was two to three orders of magnitude greater than measured bedload transport in all but the least urban streams. This excess bedload transport capacity mobilises and removes bed sediment, produces channel incision and enlargement and reduces channel complexity. Rebalancing transport capacity with sediment supply therefore requires significant flow mitigation towards pre-urban conditions. Other responses, which may theoretically help to regain this balance – channel widening, grade control, increasing roughness, sediment augmentation – are either inappropriate or only feasible following flow mitigation measures.
Small Subchondral Drill Holes Improve Marrow Stimulation of Rotator Cuff Repair in a Rabbit Model of Chronic Rotator Cuff Tear
Authors: Sun Yucheng , Kwak Jae-Man , Kholinne Erica , Zhou Youlang , Tan Jun , Koh Kyoung Hwan , Jeon In-Ho
Published: January 2020

Background:

Microfracture of the greater tuberosity has been proved effective for enhancing tendon-to-bone healing after rotator cuff repair. However, no standard diameter for the microfracture has been established.

Purpose/Hypothesis:

This study aimed to assess treatment with large- and small-diameter microfractures to enhance healing during rotator cuff repair surgery in a rabbit model of chronic rotator cuff tear. It was hypothesized that a small-diameter microfracture had advantages in terms of tendon-to-bone integration, bone-tendon interface maturity, microfracture healing, and biomechanical properties compared with a large-diameter microfracture.

Study Design:

Controlled laboratory study.

Methods:

Bilateral supraspinatus tenotomy from the greater tuberosity was performed on 21 New Zealand White rabbits. Bilateral supraspinatus repair was performed 6 weeks later. Small-diameter (0.5 mm) microfracture and large-diameter microfracture (1 mm) were performed on the left side and right side, respectively, in 14 rabbits as a study group, and simple repair without microfracture was performed in 7 rabbits as a control group. At 12 weeks later, 7 of 14 rabbits in the study group were sacrificed for micro–computed tomography evaluation and biomechanical testing. Another 6 rabbits were sacrificed for histological evaluation. In the control group, 3 of the 7 rabbits were sacrificed for histological evaluation and the remaining rabbits were sacrificed for biomechanical testing.

Results:

Significantly better bone-to-tendon integration was observed in the small-diameter microfracture group. Better histological formation and maturity of the bone-tendon interface corresponding to better biomechanical results (maximum load to failure and stiffness) were obtained on the small-diameter microfracture side compared with the large-diameter side and the control group. The large-diameter microfracture showed worse radiographic and histological properties for healing of the microfracture holes on the greater tuberosity. Additionally, the large-diameter microfracture showed inferior biomechanical properties but similar histological results compared with the control group.

Conclusion:

Small-diameter microfracture showed advantages with enhanced rotator cuff healing for biomechanical, histological, and radiographic outcomes compared with large-diameter microfracture, and large-diameter microfracture may worsen the rotator cuff healing.

Clinical Relevance:

This animal study suggested that a smaller diameter microfracture may be a better choice to enhance healing in clinical rotator cuff repair surgery in humans.
Knee Extension Deficit in the Early Postoperative Period Predisposes to Cyclops Syndrome After Anterior Cruciate Ligament Reconstruction: A Risk Factor Analysis in 3633 Patients From the SANTI Study Group Database
Authors: Delaloye Jean-Romain , Murar Jozef , Vieira Thais D. , Franck Florent , Pioger Charles , Helfer Lionel , Saithna Adnan , Sonnery-Cottet Bertrand
Published: January 2020

Background:

Cyclops syndrome is characterized by a symptomatic extension deficit attributed to impingement of a cyclops lesion within the intercondylar notch. The syndrome is an important cause of reoperation after anterior cruciate ligament reconstruction (ACLR). It has been suggested that remnant-preserving ACLR techniques may predispose to cyclops syndrome, but there is very limited evidence to support this. In general terms, risk factors for cyclops syndrome are not well-understood.

Purpose:

To determine the frequency of and risk factors for reoperation for cyclops syndrome in a large series of patients after ACLR.

Study Design:

Case-control study; Level of evidence, 3.

Methods:

A retrospective analysis of prospectively collected data was performed, including all patients who underwent primary ACLR between January 2011 to December 2017. Patients undergoing major concomitant procedures were excluded. Demographic data, intraoperative findings (including the size of preserved remnants), and postoperative outcomes were recorded. Those patients who underwent reoperation for cyclops syndrome were identified, and potential risk factors were evaluated in multivariate analysis.

Results:

A total of 3633 patients were included in the study, among whom 65 (1.8%) underwent reoperation for cyclops syndrome. Multivariate analysis demonstrated that preservation of large remnants did not predispose to cyclops lesions (odds ratio [OR], 1.11; 95% CI, 0.63-1.93). The most important risk factor was extension deficit in the early postoperative period. If present at 3 weeks postoperatively, it was associated with a >2-fold increased risk of cyclops syndrome (OR, 2.302; 95% CI, 1.268-4.239; P < .01), which was increased to 8-fold if present 6 weeks after ACLR (OR, 7.959; 95% CI, 4.442-14.405; P < .0001). None of the other potential risk factors evaluated were found to be significantly associated with an increased frequency of cyclops syndrome.

Conclusion:

Failure to regain full extension in the early postoperative period was the only significant risk factor for cyclops syndrome after ACLR in a large cohort of patients. Other previously hypothesized risk factors, such as preservation of a large anterior cruciate ligament remnant, did not predispose to the development of this debilitating postoperative complication.

Authors: Zhou Zerun , Yan Guozhen , Wang Zhiwu , Jiang Pingping , Yao Shengjian , Ding Zifan , Hua Fangfang
Published: January 2020

Objectives:

This study aims to extend the implantation lifetime of the puborectalis-like artificial anal sphincter by inhibiting the occurrence of hyperplasia following the implantation process.

Method:

A new transmission structure was designed inside the puborectalis-like artificial anal sphincter to generate an adequate torque to maintain the feces, even if hyperplasia developed around the prosthetic sphincter. An outer shell was added to the prosthetic sphincter to decelerate the occurrence of hyperplasia on the outer shell side. Medical titanium alloy was tested to replace the nylon-12 prosthetic sphincter, while polyetheretherketone was used for the construction of the power supply unit in the puborectalis-like artificial anal sphincter system instead of nylon-12. In vivo experiments were conducted to evaluate all the methods presented in this study with 10 Pa Ma piglets, 1 domestic pig, and 1 beagle dog during the past 2 years.

Results:

Compared with the previous prosthetic sphincter that was equipped with a fixed-axle gear transmission, the new transmission structure is equipped with a planet-gear train managed to generate a prosthetic sphincter output with a 53% larger torque but with the same size and type of motor as that used previously and increase the implantation lifetime by 56%. After the replacement of the nylon-12, the new prosthetic sphincter made of medical titanium alloy succeeded in extending the implanted lifetime by 83%. In addition, the lifetime was increased by 143%, when an outer shell was added to the prosthetic sphincter. Polyetheretherketone significantly decreased the growth rate of hyperplasia around the power supply unit by 44% after the replacement of the power supply unit material. After the combination of all the improvements, the longest implantation lifetime of the puborectalis-like artificial anal sphincter during the in vivo experiments was 7 months and 10 days, which reflected an improvement of 249%.

Conclusion:

All methods posted in this study were evaluated to be effective to prolong the implantation lifetime of the puborectalis-like artificial anal sphincter. Among the methods proposed, the most effective was the addition of the outer shell to the puborectalis-like artificial anal sphincter. The least effective method was the improvement of the transmission structure. Medical titanium alloy and polyetheretherketone were good replacements for nylon-12 that managed to extend the implantation lifetime and yield a moderate improvement.
Contentious Storytelling Online: Articulating Activism through Negotiation of Metanarratives
Authors: Gonzalez Victoria
Published: January 2020

Narratives are one of the primary ways that activists communicate online and as this study shows, they also prove to be a major source of contention. Analysis of two digital social justice campaigns—the #Wearethe99% narratives (associated with the Occupy Wall Street Movement) and the #BelieveinSwanQueen narratives (associated with the Swan Queen Movement)—suggests that strategies of contentious narrative development online largely involve the negotiation of metanarratives. The online narratives appear to rely upon metanarratives as a foundation for expressing broad societal grievances and personal opinions and struggles. The two dominant strategies for expressing grievances throughout the discourses are the (1) reclaiming and (2) rejecting of “The American Dream” (#Wearethe99%) and “Once Upon a Time” (#BelieveinSwanQueen) metanarratives. The negotiation of these metanarratives has led to the development of an alternative “anti-story,” which serves as narrative structure to navigate both personal and social issues.
Municipal solid waste prevention: A review of market-based instruments in six European Union countries
Authors: Magrini Chiara , D’Addato Filippo , Bonoli Alessandra
Published: January 2020

This article focuses on quantitative prevention of municipal solid waste among the 28 member countries of the European Union. A strict definition of waste prevention is used, including waste avoidance, waste reduction at source or in process, and product reuse, while recycling is outside the scope of this article. In order to provide a solid overview of the European situation, the study selected six countries (Belgium, Bulgaria, Italy, the Netherlands, Romania and Spain). Several selection requirements have been considered, such as geographic location or municipal solid waste per capita production trends from 1995 to 2017. A review of prevention programmes and other national strategic documents has been conducted. Extended producer responsibility, Pay-As-You-Throw schemes, Deposit-Refund Systems and Environmental Taxes implementation among the selected countries have been studied in order to understand how these market-based instruments can be used for the sake of waste prevention. Each market-based instrument has been further analysed using the Drivers Pressures State Impact Response model. Based on the results of this study, the effectiveness of market-based instruments implementation is strictly related to the context they are enforced in. It is particularly important to tailor the market-based instruments based on the implementation area. Nevertheless, market-based instruments, which are now mostly meant to boost the recycling sector of the considered Member States, should be designed to improve waste prevention performances, ensuring the achievement of the highest level of waste hierarchy promoted by the European Union.
Beyond Safety: Refusing Colonial Violence Through Indigenous Feminist Planning
Authors: Dorries Heather , Harjo Laura
Published: January 2020

Settler colonial violence targets Indigenous women in specific ways. While urban planning has attended to issues of women’s safety, the physical dimensions of safety tend to be emphasized over the social and political causes of women’s vulnerability to violence. In this paper, we trace the relationship between settler colonialism and violence against Indigenous women. Drawing on examples from community activism and organizing, we consider how Indigenous feminism might be applied to planning and point toward approaches to planning that do not replicate settler colonial violence.

The positive behavior interventions and supports (PBIS) framework is a well-researched framework used to teach, model, and reinforce positive behavior in schools across the country. Many residential and juvenile facilities have adopted the PBIS framework to fit a 24/7 delivery model spanning facility environments and activities (known as facility-wide PBIS [FW-PBIS]); this implementation is still in its early stages. While many FW-PBIS leadership teams report improved outcomes when implementing FW-PBIS, many continue to struggle to gain initial buy-in from youth and staff as well as sustain buy-in after initial implementation. We offer suggestions from the field to promote buy-in from key stakeholders within residential and juvenile settings.
Anatomy of the Brachycephalic Canine Hard Palate and Treatment of Acquired Palatitis Using CO2 Laser
Authors: Regalado Ibarra Adriana Margarita , Legendre Loïc
Published: January 2020

The goal of this article is to review the anatomy of the brachycephalic canine hard palate and provide a step-by-step guide on diagnosis and treatment of acquired palatitis using the CO2 surgical laser. Brachycephalic breed-related defects are not only limited to the upper airways, some dogs may develop secondary systemic or localized problems. An abnormality that is over-represented in some breeds such as boxers and bulldogs is prominent palatal rugae. The greater depth of the palatal rugae allows for the entrapment of plaque, food debris and hair. Thus, acquired palatitis or granulomatous lesions may develop. This oral pathology and its consequences are commonly neglected by the owners and frequently missed by the veterinarians. Scientific evidence-based diagnosis and treatment for this breed-related oral pathology are absent in the veterinary literature. This article is the first in providing the elements needed for an adequate morphological characterization of the canine hard palate, allowing veterinarians to appropriately identify anomalous areas of the soft tissue component of the hard palate. This article illustrates the use of a noninvasive surgical technique to prevent and cure the sequelae associated with anomalous palatal rugae. The CO2 surgical laser provides a suitable method by offering the fast resolution of the lesions and permanent results.

Lithium is one of the most powerful and commonly used medications for the treatment of various psychiatric diseases, especially bipolar disorder. However, it has a narrow therapeutic index with toxic effects on various organs. There are several case reports of lithium-induced arrhythmia and ischemia. The current work aimed to study the toxic effects of lithium on the heart of adult albino rats and its molecular mechanisms and the ameliorating effect of N-acetyl cysteine (NAC). Sixty adult male Wistar albino rats were classified into four groups; control, NAC-treated received NAC 500 mg/kg/week dissolved in 1 ml 0.9% sodium chloride intraperitoneal, lithium-treated received 52.5 mg/kg/day of lithium carbonate dissolved in 1 ml 0.9% sodium chloride orally by gavage, and lithium-and-NAC-treated (group IV) received lithium and NAC in the previous doses. After 12 weeks, the rats of group III showed a significant accumulation of ascites and a decrease in the mean arterial blood pressure and electrocardiographic (ECG) findings of ischemia and arrhythmia. In addition, there was an elevation in cardiac biomarkers creatine kinase MB (CK-MB), cardiac troponin I (cTnI), and several histological lesions with a significant increase in the area % of Van Gieson, endothelial nitric oxide synthase (eNOS), and 8-hydroxy-2′-deoxyguanosine (8-OHdG) immunoreaction. There was significant upregulation of microRNA-1, microRNA-21 (miRNA-21), and microRNA-29 (miRNA-29). MiRNA-21 was strongly positively correlated to the area % of 8-OHdG, while miRNA-29 was strongly positively correlated to the area % of Van Gieson staining. NAC significantly improved the cardiotoxic effects of lithium. Being a nontoxic and safe antioxidant, NAC can be used to ameliorate lithium-induced cardiac injury.
Derangement of PaCO2 requires physician attention in acute carbon monoxide poisoning
Authors: Moon JM , Chun BJ , Cho YS
Published: January 2020

The objective was to describe the prevalence of derangement of the partial pressure of arterial carbon dioxide (PaCO2) and to determine the association between PaCO2 and adverse cardiovascular events (ACVEs) in carbon monoxide (CO)-poisoned patients. Additionally, we evaluated whether the derangement of PaCO2 was simply secondary to metabolic changes. This retrospective study included 194 self-breathing patients after CO poisoning with an indication for hyperbaric oxygen therapy and available arterial blood gas analysis at presentation and 6 h later. The incidence rate of hypocapnia at presentation after acute CO poisoning was 67.5%, and the mean PaCO2 during the first 6 h was 33 (31–36.7) mmHg. The most common acid–base imbalance in 131 patients with hypocapnia was primary respiratory alkalosis. The incidence rate of ACVEs during hospitalization was 50.5%. A significant linear trend in the incidence of ACVEs was observed across the total range of PaCO2 variables. In multivariate regression analysis, mean PaCO2 was independently associated with ACVEs (odds ratio 0.051; 95% confidence interval 0.004–0.632). PaCO2 derangements were common after acute CO poisoning and were not explainable as a mere secondary response to metabolic changes. The mean PaCO2 during the first 6 h was associated with ACVEs. Given the high incidence of ACVEs and PaCO2 derangement and the observed association between the mean PaCO2 and ACVEs, this study suggests that (1) PaCO2 should be monitored in the acute stage to predict and/or prevent ACVEs and (2) further investigation is needed to validate this result and explore the early manipulation of PaCO2 as a treatment strategy.
Epistemic Injustice and Judicial Discourse on Transgender Rights in India: Uncovering Temporal Pluralism
Authors: Jain Dipika , Rhoten Kimberly M.
Published: January 2020

This article examines how efforts at legal legibility acquisition by gender diverse litigants result in problematic (e.g., narratives counter to self-identity) and, at times, erroneous discourses on sex and gender that homogenize the litigants themselves. When gender diverse persons approach the court with a rights claim, the narrative they present must necessarily limit itself to a normative discourse that the court may understand and, therefore, engage with. Consequently, the everyday lived experiences of gender diverse persons are often deliberately erased from the narrative as litigants mould themselves into the pre-existing normative legal categories of gender and sex. As a result of such mechanisms, the article finds that gender diverse litigants face epistemic injustice in the courts as their legal legibility is constructed within a constraining gender binary paradigm of judicial discourse.

The article explores the trajectory of transgender rights in India, through an analysis of case law prior to and post the landmark NALSA decision, to understand how the approach to transgender rights and identities has been shaped by and shapes, in turn, normative conceptions of gender. The article argues for the incorporation of temporal pluralism into the law that would allow courts to hear gender diverse litigant accounts premised on contemporary gender diversity beyond the binary (rather than incontestable prior understandings based in past precedent), which would better account for such social injustices.
The Present of the Past: The Plurality of Competing Narratives in the EU Context
Authors: Stoicheva Maria
Published: January 2020

This article intends to review the relationship between European organization and diversity. Europe lives in the legacy of division of nation and ethnicity as its main source dating from the nineteenth century. Although a hyper-real Europe has emerged overcoming its deeply divided meaning, the memory of the dividing past lives in other guises. I intend to look at current lines of division (east and west, north and south, new and old, rich and poor), considered as critical fault lines in European identity formation, turning to the notion of narrative identity, which builds upon philosophical accounts of identity in terms of continuity of self and collective consciousness, thus upon the story of space-time which makes sense for the individual and for the cultural group. The focus is intended to be on the potential for cross-fitting of particular narratives and their embedding in wider narratives (political and cultural, including values), on the potential of imagining of European unity, on uniting chronicle cultures and restructuring the interaction of multiple identities on political as well as on ethical grounds. The approach is linked to perspectives from Judt, Berlin, Delanty, Garcia, Gilbert, Nikolaidis, Trenz and also refers to the so-called ‘narrative turn’ in European studies.
