Authors: Ahmad Daud , Mahmood M. Khalid , Xin Qin , Tawfiq Ferdous M. O. , Bashir Sadia , Khalid Arsha
Published: September 2022

A computational model is presented to find the q‐Bernstein quasi‐minimal Bézier surfaces as the extremal of Dirichlet functional, and the Bézier surfaces are used quite frequently in the literature of computer science for computer graphics and the related disciplines. The recent work [1–5] on q‐Bernstein–Bézier surfaces leads the way to the new generalizations of q‐Bernstein polynomial Bézier surfaces for the related Plateau–Bézier problem. The q‐Bernstein polynomial‐based Plateau–Bézier problem is the minimal area surface amongst all the q‐Bernstein polynomial‐based Bézier surfaces, spanned by the prescribed boundary. Instead of usual area functional that depends on square root of its integrand, we choose the Dirichlet functional. Related Euler–Lagrange equation is a partial differential equation, for which solutions are known for a few special cases to obtain the corresponding minimal surface. Instead of solving the partial differential equation, we can find the optimal conditions for which the surface is the extremal of the Dirichlet functional. We workout the minimal Bézier surface based on the q‐Bernstein polynomials as the extremal of Dirichlet functional by determining the vanishing condition for the gradient of the Dirichlet functional for prescribed boundary. The vanishing condition is reduced to a system of algebraic constraints, which can then be solved for unknown control points in terms of known boundary control points. The resulting Bézier surface is q‐Bernstein–Bézier minimal surface.
Combining Self-Supervised Learning and Yolo v4 Network for Construction Vehicle Detection
Authors: Zhang Ying , Hou Xuyang , Hou Xuhang
Published: September 2022

At present, there are many application fields of target detection, but it is very difficult to apply intelligent traffic target detection in the construction site because of the complex environment and many kinds of engineering vehicles. A method based on self-supervised learning combined with the Yolo (you only look once) v4 network defined as “SSL-Yolo v4” (self-supervised learning-Yolo v4) is proposed for the detection of construction vehicles. Based on the combination of self-supervised learning network and Yolo v4 algorithm network, a self-supervised learning method based on context rotation is introduced. By using this method, the problem that a large number of manual data annotations are needed in the training of existing deep learning algorithms is solved. Furthermore, the self-supervised learning network after training is combined with Yolo v4 network to improve the prediction ability, robustness, and detection accuracy of the model. The performance of the proposed model is optimized by performing five-fold cross validation on the self-built dataset, and the effectiveness of the algorithm is verified. The simulation results show that the average detection accuracy of the SSL-Yolo v4 method combined with self-supervised learning is 92.91%, 4.83% detection speed is improved, 7–8 fps detection speed is improved, and 8–9% recall rate is improved. The results show that the method has higher precision and speed and improves the ability of target prediction and the robustness of engineering vehicle detection.

Published: September 2022

Objective. Coronary microvascular dysfunction (CMD) can complicate successful percutaneous coronary intervention (PCI). The potent endogenous vasoconstrictor peptide Endothelin-1 (ET-1) may be an important mediator. To investigate the mechanism, we sought to define the peri-procedural trans-myocardial gradient (TMG-coronary sinus minus aortic root levels) of ET-1 and its precursor peptide – Big ET-1. We then assessed correlation with pressure-wire indices of CMD: coronary flow reserve (CFR) and index of microvascular resistance (IMR). Methods. Paired blood samples from the guide catheter and coronary sinus were collected before and after pressure-wire-guided PCI from patients with stable angina. Plasma was analysed using a specific enzyme-linked immunosorbent assay for quantification of ET-1 peptides and correlated with pressure-wire data. Non normally distributed continuous variables are presented as median [IQR]. Results. ET-1 and Big ET-1 increased post-PCI in the aorta (ET-1: 0.98 [0.76–1.26] pg/ml to 1.20 [1.03–1.67] pg/ml,

P
<
0.001

and Big ET-1: 2.74 [1.78–2.50] pg/ml to 3.36 [2.33–3.97] pg/ml,

P
<
0.001

) and coronary sinus (ET-1: 1.00 [0.81–1.28] pg/ml to 1.09 [0.91–1.30] pg/ml,

P
=
0.03

and Big ET-1: 2.89 [1.95–3.83] pg/ml to 3.56 [2.66–4.83] pg/ml,

P
=
0.01

). TMG of ET-1 shifted negatively compared with baseline following PCI reflecting significantly increased extraction (0.03 [−0.12–0.17] pg/ml pre-PCI versus −0.16 [−0.36–0.07] pg/ml post-PCI,

P
=
0.01

). Increased ET-1 trans-myocardial extraction correlated with higher IMR (Pearson’s r = 0.293,

P
=
0.02

) and increased hyperemic transit time (Pearson’s r = 0.333,

P
<
0.01

). In subgroup analysis, mean ET-1 trans-myocardial extraction was higher amongst patients with high IMR compared with low IMR (0.73 pg/ml, SD:0.78 versus 0.17 pg/ml, SD:0.42,

P
=
0.02

). There was additionally a numerical trend towards increased ET-1 trans-myocardial extraction in subgroups of patients with low CFR and in patients with Type 4a Myocardial Infarction, albeit not reaching statistical significance. Conclusions. Circulating ET-1 increases post-PCI and upregulated ET-1 trans-myocardial extraction contributes to increased microcirculatory resistance.
A Neighborhood Model with Both Distance and Quantity Constraints for Multilabel Data
Authors: Jiang Xiaoli , Zhou Jing , Qiao Xinyue , Peng Chang , Su Shiwen
Published: September 2022

In this paper, a novel distance-based multilabel classification algorithm is proposed. The proposed algorithm combines k-nearest neighbors (kNN) with neighborhood classifier (NC) to impose double constraints on the quantity and distance of the neighbors. In short, the radius constraint is introduced in the kNN model to improve the classification accuracy, and the quantity constraint

k

is added in the NC model to speed up computing. From the neighbors with the double constraints, the probabilities for each label are estimated by the Bayesian rule, and the classification judgment is made according to the probabilities. Experimental results show that the proposed algorithm has slight advantages over similar algorithms in calculation speed and classification accuracy.

Published: September 2022

Background:

High-risk human papillomavirus (HR-HPV) infection is a risk factor for anal cancer, yet no anal cancer screening guidelines exist for women with lower genital tract HPV-related disease. We sought to describe the prevalence of anal HR-HPV or cytologic abnormalities in such women.

Methods:

This cross-sectional study was performed between October 2018 and December 2021. Inclusion criteria were ≥21 years of age and a prior diagnosis of high-grade dysplasia/cancer of the cervix, vagina, or vulva. Participants underwent anal cytology and anal/cervicovaginal HR-HPV testing. Women with abnormal anal cytology were referred for high-resolution anoscopy (HRA).

Results:

324 evaluable women were enrolled. Primary diagnosis was high-grade dysplasia/cancer of the cervix (77%), vagina (9%), and vulva (14%). Anal HR-HPV was detected in 92 patients (28%) and included HPV-16 in 24 (26%), HPV-18 in 6 (7%), and other HR-HPV types in 72 (78%) patients. Anal cytology was abnormal in 70 patients (23%) and included atypical squamous cells of undetermined significance (80%), low-grade squamous intraepithelial lesion (9%), high-grade intraepithelial lesion (HSIL; 1%), and atypical squamous cells-cannot rule out HSIL (10%). Of these patients, 55 (79%) underwent HRA. Anal biopsies were performed in 14 patients: 2 patients had anal intraepithelial neoplasia (AIN) 2/3, 1 patient had AIN 1, and 11 patients had negative biopsies. Both patients with AIN 2/3 had a history of cervical dysplasia.

Conclusions:

Our results suggest an elevated risk of anal HR-HPV infection and cytologic abnormalities in women with lower genital tract dysplasia/cancer.

Impact:

These results add to the growing body of evidence suggesting the need for evaluation of screening methods for anal dysplasia/cancer in this patient population to inform evidence-based screening recommendations.
Hope, Cure, and Adverse Effects in Immunotherapy: Atezolizumab-Associated Encephalitis in Metastatic Small Cell Lung Cancer – A Case Report and Literature Review
Authors: Ibrahim Eiman Y. , Zhao Weige Charlie , Mopuru Haritha , Janowiecki Christopher , Regelmann David J.
Published: September 2022

Cancer immunotherapies have been revolutionary treatments in oncological disease. Such therapies include immune checkpoint inhibitors that target programmed cell death protein, ligands, and cytotoxic T-lymphocyte-associated antigen (CTLA-4). Increased use has led to recognition of immune-related adverse events. Such events are often distinct from the typical adverse events of traditional cancer therapies. Immune-related adverse events are more commonly found to affect the skin, gastrointestinal tract, and endocrine system. The incidence of these adverse events remains low for central nervous system effects. This article describes a case of atezolizumab-associated encephalitis in a patient with metastatic small cell lung cancer.
Curcumin-QingDai Combination as Treatment for Moderate-Severe Ulcerative Colitis
Authors: Ben-Horin Shomron , Kopylov Uri , Salomon Nir
Published: September 2022

Curcumin was shown in placebo-controlled trials to induce remission in mild-moderate ulcerative colitis (UC). QingDai (QD, Indigo), another herbal extract, showed efficacy in two UC trials from Japan, but evidence in the Western population is scant. We report on the use of curcumin-QingDai combination (CurQD) for the treatment of moderate-severe UC. Patient 1 was a 24-year-old male with severe UC refractory to cyclosporine and corticosteroids. He partially responded to infliximab but later lost response to an optimized dose of infliximab in combination with 6-mercaptopurine, presenting with worsening symptoms and severe Mayo 3 mucosal inflammation. Initiation of CurQD 2.5 g/day resulted in rapid cessation of blood per rectum. Complete clinical remission ensued within few weeks. Follow-up endoscopies performed 12 weeks later showed only minimal residual inflammation. Infliximab was later stopped due to reimbursement issues, and the patient was successfully maintained on lower doses of CurQD and 6-mercaptopurine for 31 months. Two flares have responded to a temporary increase in QD component dose. Patient 2 was a 59-year-old female with extensive UC not responding to maximal oral + topical 5-ASA and corticosteroids. Despite severe mucosal ulceration (Mayo 3) found on endoscopy, she refused the recommendation for biologics and opted for a short-term limited trial of CurQD. This was initiated at 2,000 mg/day and induced rapid clinical remission. Lower endoscopies performed after 2 and 5 months on CurQD showed complete mucosal healing, and the patient maintained her clinical remission on low-dose CurQD for 49 months. No adverse events were noted in the 2 patients.

Memória e Escrita: A Dupla Marca do Povo Judeu, em A Chave de Casa, de Tatiana Salem Levy
Authors: Menezes Jessica Sabrina de Oliveira
Published: September 2022

Este trabalho aborda a necessidade da escrita – que se projeta sobre a personagem narradora do romance A chave de casa (2007), de Tatiana Salem Levy – como uma marca do povo judeu. A personagem em questão empreende uma atividade de reescrita da tradição/percurso migratório familiar. Isso deságua num processo tradutório que contribui para a manutenção da memória familiar (e judaica). Para realizar o estudo, filiamo-nos especialmente aos pensamentos de Derrida (1994, 2001), Halbwachs (2006), Lilenbaum (2009), Perrone-Moisés (2006) e Bezerra (2007).

Medical Therapy for Functional Mitral Regurgitation
Authors: Milwidsky Assi , Mathai Sheetal Vasundara , Topilsky Yan , Jorde Ulrich P.
Published: September 2022

Functional mitral regurgitation (FMR) can be broadly categorized into 2 main groups: ventricular and atrial, which often coexist. The former is secondary to left ventricular remodeling usually in the setting of heart failure with reduced ejection fraction or less frequently due to ischemic papillary muscle remodeling. Atrial FMR develops due to atrial and annular dilatation related to atrial fibrillation/flutter or from increased atrial pressures in the setting of heart failure with preserved ejection fraction. Guideline-directed medical therapy is the first step and prevails as the mainstay in the treatment of FMR. In this review, we address the medical therapeutic options for FMR management and highlight a targeted approach for each FMR category. We further address important clinical and echocardiographic characteristics to aid in determining when medical therapy is expected to have a low yield and an appropriate window for effective interventional approaches exists.
Definition of Optimal Optical Coherence Tomography–Based Stent Expansion Criteria: In-Stent Minimum Lumen Area Versus Residual Stent Underexpansion

Published: September 2022

Background:

The mismatch between in-stent minimum lumen area (sMLA) and reference vessel lumen area, defined as stent underexpansion (SU), could be an important determinant of stent failure. We tested the clinical predictive value of absolute sMLA in comparison to relative SU in the context of the CLI-OPCI (Centro Per La Lotta Contro L’Infarto-Optimisation of Percutaneous Coronary Intervention) project registry.

Methods:

We retrospectively analyzed end procedural optical coherence tomography findings in 1211 patients (1422 lesions) undergoing percutaneous coronary intervention, assessing the prevalence and magnitude of residual SU and exploring correlation with outcome in comparison with sMLA.

Results:

In our series, both sMLA and SU were related to vessel size and anatomic lesion complexity. When compared with patients without adverse event at follow-up, those experiencing device-oriented cardiovascular events (composite of cardiac death, target vessel myocardial infarction, target lesion revascularization, and stent thrombosis) showed a lower sMLA (5.6±2.1 versus 6.1±2.1 mm
2
;
P
=0.011) but a comparable degree of SU (11.6±14.1% versus 11.2±13.3%;
P
=0.734). The prespecified cutoff value of sMLA <4.5 mm
2
, documented in 23.8% of cases, was confirmed as independent outcome predictor for device-oriented cardiovascular events (hazard ratio [HR], 2.05 [95% CI, 1.5–2.9]) including target lesion revascularization (HR, 2.43 [95% CI, 1.7–3.5]) and stent thrombosis (HR, 3.23 [95% CI, 1.7–6.3]). A residual SU of 10%, 20%, and 30% was observed in 38.0%, 18.2%, and 7.6% of cases, respectively. No grade of residual SU significantly increased the risk of stent failure, unless if an SU >20% was associated with an sMLA <4.5 mm
2
(HR, 3.11 [95% CI, 1.7–5.6]). Finally, an association between stent overexpansion (ie, >110%) and device-oriented cardiovascular events was also observed (HR, 1.60 [95% CI, 1.1–2.3]).

Conclusions:

Final absolute sMLA and not relative SU was associated with an increased risk of stent failure. A variable grade of SU was common, but it resulted in being clinically relevant only when associated with an sMLA <4.5 mm

All Fun and Games? Relationships between Finnish Police Dogs and Their Handlers
Authors: Ahto-Hakonen Jenni , Hakonen Aki
Published: September 2022

The paper presents the first cultural anthropological study of the Finnish canine police force. The study is based on interviews with eleven police dog handlers. The interviews focused on the cultural model of the profession, with emphasis on the interaction between dogs and their handlers. The relationship is surprisingly reciprocal. It can be understood as operating on the principles of an interspecies social contract, where the categorical division between the species is, paradoxically, vigorously maintained and habitually broken. The police dog requires constant negotiation to perform tasks that humans themselves cannot do. Rather than being forced, the dogs are guided through play and positive reinforcement into performing tasks. Relationships of canine police teams are deeply personal and in navigating the complexities of a human-driven society, the canine assumes many different roles. Conceptualizing police dogs as mediators for their natural talents, instead of mere tools, could formalize their place in society.
Bardesane et l’herméneutique des Écritures : l’étude des nouveaux témoignages
Authors: Jurasz Izabela
Published: September 2022

Very little is known about the use of Scripture by Bardaisan, the Syriac-speaking Christian philosopher. The scholars have identified a few biblical references and terms, but they found that quotations are extremely rare. Even more so, it is difficult to state an opinion on Bardaisan’s exegetical method. Research has focused on Ephraim’s Memrā against Bardaisan and his passages concerning the reading of Jn 8:51. Now, it is possible to broaden the area of research on the testimony of Eusebius of Emesa – preserved in Armenian – about Bardaisanite exegesis of Gen 6:22 and Gen 7:1, as well as on the uses the Scriptures by Bardaisanite who intervenes in Adamantios’s Dialogue on Right Faith in God. The analysis of this new evidences shows that Bardaisan and his followers practised literal exegesis in the tradition of the Antiochian school.

Il existe très peu d’informations sur l’utilisation des Écritures par Bardesane, le philosophe chrétien de langue syriaque. Les spécialistes ont identifié surtout des allusions et expressions bibliques, mais les citations restent extrêmement rares. À plus forte raison, il est difficile de se prononcer sur la méthode exégétique de Bardesane. Les recherches ont été concentrées sur le Memrā contre Bardesane d’Éphrem et ses passages concernant la lecture de Jn 8, 51. Cependant, il est possible d’élargir le champ de recherche sur le témoignage d’Eusèbe d’Émèse – conservé en arménien – au sujet de l’exégèse bardesanite de Gn 6, 22 et Gn 7, 1, ainsi que sur la manière d’utilisation des Écritures par le bardesanite qui in-tervient dans le Dialogue sur la juste foi en Dieu d’Adamantios. L’analyse de ce nouveau dossier montre que Bardesane et ses disciples ont pratiqué l’exégèse littérale, dans la tradition de l’école d’Antioche.
“I need to protect everyone”
Authors: Davey Christopher P.
Published: September 2022

This article examines violent masculinity and locates this performative identity within ethnic conflict and African masculinity literature. Analysis focuses on the development of Congolese Banyamulenge soldiers’ masculine narratives and moral justifications of violence. The article responds to this question: what is Banyamulenge violent masculinity, and how has it developed? The process of how Banyamulenge masculinity evolved in response to perceptions of threat, and elements of genocide are present. These men considered themselves the final protectors of Tutsis regionally and in the Congo, deploying a degree of exceptionalism. Using narrative analysis, this article engages the above literature and original fieldwork interviews with Banyamulenge soldiers and political actors. The concept of violent masculinity addresses the masculinity gap of broader ethnic conflict literature. This article also offers a significant empirical contribution in terms of Banyamulenge involvement in local and regional conflicts. Violent masculinity evolved as a Banyamulenge practice, whilst being embedded in traditional structures.
Prolonging the Response Movement Reduces Commission Errors in a High-Go, Low-No-Go Target Detection Task and Composite Metrics of Performance Miss This Effect
Authors: Mensen Justin M. , Holland Steven B. , Helton William S. , Shaw Tyler H. , Peterson Matthew S.
Published: September 2022

Objective

Expand research on the Sustained Attention to Response Task (SART) to a more applied agricultural target detection/selection task and examine the utility of various performance metrics, including composite measures of speed and accuracy, in a High-Go/Low-No-Go stimuli task.

Background

Modified SARTs have been utilized to investigate mechanisms, such as failures of response inhibition, occurring in friendly fire and collateral damage incidents. Researchers have demonstrated that composite measures of speed and accuracy are useful for Low Go/High No-Go stimuli tasks, but this has not been demonstrated for High-Go/Low-No-Go tasks, such as the SART.

Method

Participants performed a modified SART, where they selected (“sprayed”) images of weeds (Go stimuli) that appeared on a computer screen, while withholding to rarer soybean plant images (No-Go stimuli).

Results

Response time was a function of distance from a central starting point. Participants committed commission errors (sprayed the soybeans) at a significantly higher rate when the stimuli appeared under the cursor centered on the screen for each trial. Participant’s omission errors (failure to spray a weed) increased significantly as a function of distance. The composite measures examined were primarily influenced by response time and omission errors limiting their utility when commission errors are of particular interest.

Conclusion

Participants are far more accurate in their decision making when required to execute a longer duration motor task in High-Go/Low-No-Go experiments.

Application

Demonstrates a serious human factors liability of target detection and snap-to-target systems.
Unintended Effects of Policy Interactions in the Health Sector: A Case of Kerala, India
Authors: Dayashankar Maurya , Hense Sibasis
Published: September 2022

The governments of developing countries, including India, are pursuing policy mixes in collaboration with the private sector to strengthen the public health system. However, little is known about the interaction of public policies with different instrument logics. We conducted a contextual analysis of two health policies with different instrument logics—emergency care and social health insurance programme—for over a decade in Kerala, employing primary and secondary data, government reports, newspaper articles, and published and unpublished literature. Our analysis suggests that the competition between policies has led to policies working at crossroads. The low political salience of emergency care has led to the diversion of resources and attention to government health insurance programmes. Thus, emergency care is increasingly facilitated at private facilities, shifting the government’s role from service delivery to financing. Our findings also highlight that the interaction effects among health policies receive limited attention among researchers and practitioners. These findings are relevant to countries of similar economies undergoing New Public Management reforms leading to the weakening of the public system in dealing with health functions such as emergency care.

Authors: Shono Yuji , Mezuki Satomi , Akahoshi Tomohiko , Nishihara Masaaki , Kaku Noriyuki , Maki Jun , Tokuda Kentaro , Kitazono Takanari
Published: September 2022

Objective

This study was performed to evaluate the correlation between parameters measured by bedside ultrasonography and detection of intracranial organic lesions in patients with impaired consciousness in an intensive care unit (ICU) setting.

Methods

We retrospectively reviewed the medical records of patients who were admitted to our ICU from April 2017 to July 2019. Patients who underwent computed tomography or magnetic resonance imaging examination and measurement of the flow velocity of the carotid and intracranial arteries and the optic nerve sheath diameter by ultrasonography were selected for analysis.

Results

In total, 64 patients were analyzed in this study. Of these, intracranial lesions were detected by computed tomography or magnetic resonance imaging in 17 (27%) patients. The left:right ratio of the end-diastolic velocity of the bilateral common carotid artery (CCA-ED ratio) and the pulsatility index of the middle cerebral artery (MCA-PI) were significantly higher in patients with than in those without intracranial lesions. The cut-off value of the CCA-ED ratio was 1.55 (sensitivity, 66.7%; specificity, 81.6%), and that of the MCA-PI was 1.21 (sensitivity, 57.1%; specificity, 76.7%).

Conclusion

Bedside ultrasonography is useful for predicting intracranial lesions requiring therapeutic intervention in ICU patients with impaired consciousness.
Long-term outcomes regarding arterial stiffness and carotid artery atherosclerosis in female patients with rapid eye movement obstructive sleep apnea
Authors: Suzuki Mayumi , Shimamoto Ken , Tatsumi Fujio , Tsuji Takao , Satoya Natsumi , Inoue Yuji , Hoshino Tetsuro , Shiomi Toshiaki , Hagiwara Nobuhisa
Published: September 2022

Objective

Rapid eye movement (REM) obstructive sleep apnea (OSA) is associated with the risk of cardiovascular events. Arterial stiffness and carotid artery intima-media thickness (IMT) predict these events, but few relevant studies have been conducted. We compared long-term changes in arterial stiffness and IMT between patients with REM OSA and non-REM (NREM) OSA receiving continuous positive airway pressure (CPAP) or oral appliance (OA) therapy.

Methods

Newly diagnosed female patients with OSA received CPAP (n = 6) or OA (n = 7). Pulse wave velocity (PWV) and carotid artery ultrasound were performed before and 60 months after treatment.

Results

There were no differences in baseline characteristics (mean age: 56.0 vs. 61.3 years; mean body mass index: 22.6 vs. 21.7 kg/m2) between the REM OSA and non-REM OSA groups. The median apnea-hypopnea index was lower in the REM OSA group than in the non-REM OSA group. Increased PWV (12.92 ± 1.64 to 14.56 ± 2.73 m/s) and deteriorated glucose metabolism were observed in the REM OSA group after treatment. PWV, IMT, and cardiovascular risk factors were unaffected in the non-REM OSA group.

Conclusion

Arterial stiffness and glucose metabolism are deteriorated in patients with REM OSA compared with these parameters in patients with non-REM OSA after CPAP or OA treatment.
Iliac vein compression syndrome caused by a large bladder diverticulum: Case report and literature review
Authors: Wang Xuebin , Chen Xueming , Gao Xiang , Feng Hai
Published: September 2022

Iliac vein compression syndrome is a rare disorder that causes oedema of one or both legs, with or without thrombosis. This current case report describes a 71-year-old male patient with left iliac vein compression caused by a bladder diverticulum that occurred secondary to chronic prostatic hyperplasia. The patient presented with left leg oedema without deep vein thrombosis. Contrast-enhanced computed tomography of the abdomen and pelvis, Doppler ultrasound imaging of the lower limb veins and magnetic resonance imaging helped confirm the diagnosis. The patient initially underwent urinary catheter placement, which relieved urinary retention and iliac vein compression. He subsequently underwent bladder diverticulectomy and transurethral prostatectomy. The postoperative clinical course was uneventful. During the 1.5-year follow-up, the patient did not have lower extremity oedema. Bladder diverticulum is an extremely rare cause of iliac vein compression syndrome, and only five such cases, including this one, have been reported to date. This article presents a literature review of these cases and a summary of the diagnosis and treatment experience.

Published: September 2022

Ovarian pregnancy is rare but may occur with in vitro fertilization-embryo transfer in women who have undergone bilateral salpingectomy. We report a case of an approximately 30-year-old woman who had in vitro fertilization and a history of bilateral salpingectomy, and was diagnosed with an ovarian pregnancy. Laparoscopic enucleation of the gestational product in the ovary and ovarian remnant reconstruction were performed. The patient recovered well after surgery and was discharged home 5 days postoperatively. ß-human chorionic gonadotropin was undetectable 3 weeks after the surgery. Awareness of the possibility of ovarian pregnancy after in vitro fertilization-embryo transfer is the most important step in an early diagnosis and treatment. Salpingectomy should be carefully performed to eliminate the risk of heterotopic pregnancy, especially in cases where a subsequent gestation is desired.
Childhood Sexual Abuse and Military Sexual Trauma Interact to Increase Suicide Risk: Results from a Nationally Representative Veteran Sample
Authors: Holliday Ryan , Nichter Brandon , Holder Nicholas , Hill Melanie L. , Monteith Lindsey L. , Norman Sonya B. , Pietrzak Robert H.
Published: September 2022

Childhood sexual abuse (CSA) and military sexual trauma (MST) are prevalent among veterans. Such exposures are associated with adverse mental-health sequelae, including elevated risk for suicidal thoughts and behaviors. Nonetheless, prior studies have largely focused upon discrete experiences of CSA or MST in circumscribed samples. In the current study, we analyzed data from a large, nationally representative sample of 4,069 US military veterans to examine main and interactive effects of CSA and MST in relation to suicidal thoughts and behaviors. After accounting for sociodemographics, psychiatric comorbidity, and trauma-related characteristics, we detected a significant interaction between MST and CSA as it related to report of past-year suicidal ideation, lifetime suicide attempt, and risk for future suicide attempt. These findings underscore the impact of sexual trauma throughout the lifespan, highlighting the continued importance of screening for trauma exposure and connecting veterans to appropriate, evidence-based treatment to decrease their risk for suicidal thoughts and behaviors.
Intermediary Public Policy Organizations and the Discursive Evasion of Systemic Racism and Racialized Violence
Authors: McCoy-Simmons Casey , Orphan Cecilia M. , Gándara Denisa
Published: September 2022

The 2020 health pandemic and high-profile police murders of Black people inspired national conversations about racism and police brutality. This study examined how Intermediary Public Policy Organizations (IPPOs) discursively engaged with the racialized nature of the pandemic and the police murder of George Floyd, which have increased awareness of systemic racism in society. Our discursive analysis of IPPO statements published during these events revealed a pattern of humanizing higher education institutions, race evasive policy proposals, and a lack of policy action addressing systemic racism. IPPO evasion of race is consequential because it has the potential to limit the ability of public policy to dismantle systems of oppression and highlights the need for race-conscious policies to support Black, Indigenous, and people of color students and communities.

Background: The sonographic posterolateral rotatory stress test may be a good preoperative diagnostic tool for posterolateral rotatory instability, especially in atraumatic or occult cases. However, there is lack of study on the living population or the normal elbow. Hypothesis/Purpose: This study evaluates the ulnohumeral opening gap difference between elbows in resting and stress positions while performing ultrasonography in normal healthy volunteers. The hypothesis is that the normal ulnohumeral opening gap difference is less than 2 mm. Methods: A total of 21 participants (9 males and 12 females) who presented at our institution between May and June 2021 were recruited. First, participants with elbow deformity, major elbow trauma, history of injection or surgery around the elbow, or evidence of elbow instability were excluded. Only healthy elbows without symptoms were included in this study. Participants’ both elbows were examined using ultrasonography. The ulnohumeral gap was measured in millimeters, and the difference was calculated from the means of ulnohumeral gap in resting and stress positions. Results: The mean age of participants was 36.14 years old. No samples with hyperlaxity were included. Overall, the means of ulnohumeral gap in resting and stress positions were 2.55 ± 0.69 mm and 3.16 ± 0.80 mm, respectively. The average mean of overall ulnohumeral opening gap difference was 0.61 ± 0.32 mm. There was no statistically significant difference between males and females ( p = .989). The intraobserver reliability was 0.89 and 0.9 for resting and stress positions, respectively. Conclusion: The sonographic posterolateral rotatory stress test shows that the ulnohumeral opening gap difference between resting and stress positions is less than 2 mm in healthy volunteers. Clinical Relevance: In patients with inconclusively-diagnosed PLRI, the sonographic posterolateral rotatory stress test may be a reliable preoperative diagnosis tool, providing its non-invasiveness and the ability to assess the contralateral side as a comparison.
Integrating Policy into School Safety Theory and Research
Authors: Astor Ron Avi , Benbenishty Rami
Published: September 2022

Multiple fields including social work, public health, psychology, and education have been researching school safety issues for the past 40 years. Findings from research and intervention have been a driving force in school safety policy change. Likewise, policy and funding patterns created have dramatically altered how and what school safety researchers study. Yet school safety policy has not been the focus of empirical studies in social work or other research fields as either independent or dependent variables. Based on prior work and current school safety policy issues, the authors created a new theoretical ecological model to generate a conceptual policy-focused model of school safety. They identified thematic, conceptual, methodological, and analytic gaps in the school safety literature using the new model as a guide. Examples from policy and empirical work are given to elucidate the conceptual model. Suggestions are made for researchers and universities to close the gap between school safety research and policy.
Effect of Method Bias on the Internal Structure of the Systemic Clinical Outcomes in Routine Evaluation Measure of Family Functioning
Authors: Peterson Christina Hamme , Peterson N. Andrew , Casey Corinne
Published: September 2022

This study was conducted to test for method bias stemming from mixing positively and negatively worded items in a widely used measure of family functioning, the Systemic Clinical Outcomes in Routine Evaluation (SCORE). Data were collected from a community sample of 377 U.S. adults with children in the household, with 32% reporting greater family difficulties than a clinical pre-therapy average and 66% reporting greater difficulties than a clinical post-therapy average. Confirmatory factor analyses (CFA) were performed to test two models: Model 1, a unidimensional model in which items represented a single theoretical construct and Model 2, a multidimensional model in which items represented a method dimension (i.e., positively worded or negatively worded) as well as an underlying theoretical construct. Fit indices showed that Model 2 fit the data better than Model 1 for all dimensions tested, suggesting that method bias had detrimental effects on the factor structure of dimensions of the SCORE.

Published: September 2022

The Levels of Personality Functioning Questionnaire 12-18 (LoPF-Q 12-18) is the only self-report measure informed by the Level of Personality Functioning ( Diagnostic and Statistical Manual of Mental Disorders [5th ed.; DSM-5; American Psychiatric Association, 2013]) Alternative Model of Personality Disorders developed for adolescents. The present investigation includes two studies evaluating the English LoPF-Q 12-18. In Study 1, single-factor and bifactor structures (unidimensional severity criterion and four specific factors: identity, self-direction, empathy, intimacy) were evaluated in an ethnically diverse community sample ( N = 453; age 10–18; 57% female). Study 2 used a community control ( n = 298; age 10–18; 54.4% female) and clinical sample ( n = 94; age 11–18; 58.5% female) to examine reliability, validity, and clinical utility. Study 1 results supported the bifactor model, with a robust general factor and little multidimensionality caused by the group factors, suggesting an essentially unidimensional structure. Study 2 revealed good internal consistency and construct validity and provided clinical cut-offs, supporting the use of the LoPF-Q 12-18 total score in research and clinical applications.

Published: September 2022

Objectives

Health education may improve health in geriatric patients. To evaluate differences between remote and in-person education, the DREAMS ( Developing a Research Participation Enhancement and Advocacy Training Program for Diverse Seniors) health seminar series compared in-person and remote learning groups to assess feasibility, satisfaction, adherence, health literacy, and cognitive outcomes.

Research Design

Nonrandomized two-arm interventions occurred remotely or in-person. About 130 diverse, older adults ( M age: 70.8 ± 9.2 years; in-person n = 95; remote, n = 35) enrolled. Data from 115 completers (In-person n = 80; Remote n = 35) were analyzed for performance outcomes. Feasibility, adherence, and satisfaction benchmarks were evaluated at baseline, immediately post intervention, and 8 weeks post intervention. Adjusting for baseline performances, outcomes on health literacy and cognitive measures were compared between groups after intervention (at posttest and at 8-week follow-up) using adjusted mean differences (β coefficients).

Results

Eighty in-person and all remote participants completed at least six modules. Both programs had high satisfaction, feasibility, and strong adherence. After adjusting for demographic covariates and baseline values, cognitive and motor cognitive measures between groups were domain specific (e.g., global cognition, executive function, spatial memory, mental tracking capacity, and cognitive integration).

Discussion and Implications

This work explores feasible measures of knowledge acquisition and its link to health literacy and cognitive outcomes. Identifying effective delivery methods may increase involvement in clinical research. Future studies may encourage remote learning for increased accessibility.

Culturally-adapted evidence-based programs (EBPs) are needed to promote healthy behaviors among Native teens and young adults. Little is known about the facilitators and barriers of implementing and sustaining EBPs in Native communities. This paper aims to identify those factors described by educators who implemented the Native Students Together Against Negative Decisions (STAND) curriculum. Methods. We conducted qualitative, semi-structured interviews with 44 Native STAND educators from 48 sites throughout the United States. We used a modified grounded theory approach to explore barriers, facilitators, and sustainability factors related to implementing Native STAND. Results. We learned that disruptions to staffing, coordination, and organizational factors were the most common barriers. Factors that improved implementation success included: tailoring the program to local needs/constraints, having a supportive Project Manager, improved fidelity due to check-in calls, and participation in summer training. Factors that improved sustainability included: access to needed infrastructure, administrative support, community support, and student interest. Discussion. The delivery of Native STAND was further improved by person-to-person communication and resource sharing across sites. Sustaining EBPs in AI/AN settings requires culturally-tailored technical assistance, sufficient implementation funds for materials and staffing, and a community of peer educators to inspire forward progress. Conclusion. EBPs that reflect the needs and experiences of American Indian and Alaska Native (AI/AN) youth are necessary to address systemic inequities in adolescent health outcomes. The Native STAND Dissemination and Implementation study is among the first to assess facilitators and barriers to program delivery in diverse AI/AN settings.

Introduction

Child-centered play therapy (CCPT) is a practical and recommended non-medication intervention for children with Attention-deficit/hyperactivity disorder (ADHD) but the mechanism in between is unclear.

Aim

This study proposed to examine the effectiveness of CCPT on neuropsychological deficits and behavioral symptoms in ADHD.

Methods

Participants with ADHD diagnosis were referred from senior child and adolescent psychiatrists, and typical developmental children (TD) were recruited from community as a control group. All participants’ executive functions were evaluated using Cambridge Neuropsychological Test Automated Battery. First of all, the participants were evaluated using Child Behavior Checklist (CBCL) by their parents. The ADHD participants were assigned into CCPT (ADHDc) and waitlist (ADHDw) group; and the ADHDc group then received CCPT weekly for 12 sessions, while the ADHDw continuously received their regular treatment (i.e., medication treatment or other alternative treatments) as usual.

Results

Total 52 participants were recruited (17 with ADHD and 35 typically developed children, TD). The results showed that overall the ADHD groups had worse neuropsychological performance and more behavioural disturbance than did the TD ( ps < .05). After receiving the CCPT, the results showed that the ADHDc group had significant improvement in the cognitive flexibility ( p < .05); while the ADHDw group had no changes.
Researching the digital economy and the creative economy: Free gaming shards and commercialised making at the intersection of digitality and creativity
Authors: Jordan Tim , Richterich Annika
Published: September 2022

Despite the creative economy relying on digital technology and the digital economy needing creative input, policy and research alike tend to miss or underestimate interdependencies between these two economies. This article argues for the importance of acknowledging interdependencies and overlaps between the cultural and creative economy and the digital economy – while likewise refraining from implicitly conflating the two. Starting from a comparative literature review that identifies key features of creative economy and digital economy literature and the few detailed works on overlaps, it elaborates on this argument by examining two case studies. In discussing and comparing digital games and do-it-yourself electronics e-commerce, this article illustrates overlaps of practices relevant to both, digital and creative economy, and elaborates on why it matters to acknowledge interdependencies rather than merging the two.
A rising tide lifts all boats: Group performance and intragroup status
Authors: Flynn Francis J. , Xu Chunchen
Published: September 2022

Early theories of status dynamics in small groups portrayed intragroup status as a limited resource—as the status of one group member rises, the status of another must fall. Recent theorizing presents an alternative view: that the amount of status available to group members can be variable rather than fixed. Building on this view, we theorize that the average level of intragroup status changes as a function of group performance, such that the intragroup status of an average group member is higher in groups with higher performance and lower in groups with lower performance. We further theorize that changes in group solidarity partly account for the link between group performance and intragroup status. Across three preregistered studies, we find support for these hypotheses, which we hope will kindle interest in identifying other factors that can account for changes in intragroup status equilibria.
