Primary healthcare professionals’ perspective on vertical integration of healthcare system in China: a qualitative study
Authors: Yuan Shasha , Fan Fengmei , van de Klundert Joris , van Wijngaarden Jeroen 
Published: February 2022

ObjectiveThis study aims to present the perspectives of primary healthcare professionals (PHPs) on the impacts of implementation of vertical integration and on the underlying interprofessional collaboration process on achievement of the policy goals in China.DesignA qualitative study involving individual interview and group interview was conducted between 2017 and 2018.SettingPrimary healthcare institutions (PHIs) in five counties/districts of China.ParticipantsThe major participants include 12 heads of PHIs (by 12 individual interviews) and 38 PHPs (by 12 group interviews). We also interviewed other stakeholders including 24 health policy-makers (by 5 group interviews) and 5 hospital leaders (by 5 individual interviews) for triangulation analysis.ResultsOur study indicates that PHPs perceived vertical integration has resulted in improved professional competency, better care coordination and stronger capacity to satisfy patients’ needs. The positive impacts have varied between integration types. Contributing factors for such progress are identified at administrative, organisational and service delivery levels. Other perceived effects are a loss of autonomy, increased workload and higher turnover of capable PHPs. Higher level hospitals play a dominant role in the interprofessional collaboration, particularly regarding shared goals, vision and leadership. These findings are different from the evidence in high-income countries. Incentive mechanisms and the balance of power with hospitals management are prominent design elements in the future.ConclusionsOur findings are particularly valuable for other countries with a fragmented health service system and low competency of PHPs as China’s experience in integrated care provides a feasible path to strengthen primary care.

ObjectivesSince the onset of the COVID-19 pandemic, behavioural interventions to reduce disease transmission have been central to public health policy worldwide. Sustaining individual protective behaviour is especially important in low-income and middle-income settings, where health systems have fewer resources and access to vaccination is limited. This study seeks to assess time trends in COVID-19 protective behaviour in India.DesignNationally representative, panel-based, longitudinal study.SettingWe conducted a panel survey of Indian households to understand how the adoption of COVID-19 protective behaviours has changed over time. Our data span peaks and valleys of disease transmission over May–December 2020.ParticipantsRespondents included 3719 adults from 1766 Indian households enrolled in the Harmonised Diagnostic Assessment of Dementia for the Longitudinal Ageing Study in India.AnalysisWe used ordinary least squares regression analysis to quantify time trends in protective behaviours.ResultsWe find a 30.6 percentage point (95% CI (26.7 to 34.5); p<0.01) decline in protective behaviours related to social distancing over the observation period. Mask wearing and handwashing, in contrast, decreased by only 4.3 percentage points (95% CI (0.97 to 7.6); p<0.05) from a high base. Our conclusions are unchanged after adjusting for recorded COVID-19 caseload and nationwide COVID-19 containment policy; we also observe significant declines across socioeconomic strata spanning age, gender, education and urbanicity.ConclusionWe argue that these changes reflect, at least in part, ‘COVID-19 fatigue,’ where adherence to social distancing becomes more difficult over time irrespective of the surrounding disease environment.
The effect of the long-term inhibition of hydrogen sulfide production on the reactivity of the cardiovascular system in Wistar rats
Authors: Drobna Magdalena , Berenyiova Andrea , Cacanyiova Sona 
Published: February 2022

In this study, we investigated the blood pressure responses of the peripheral bed in vivo after chronic hydrogen sulfide (H2S) inhibition combined with acute nitric oxide (NO) deficiency. We also evaluated the role of endogenously produced H2S in the vasoactive responses of large- and medium-sized arteries in vitro. Changes in integrated blood pressure responses were measured after chronic inhibition of cystathionine-γ-lyase, an enzyme involved in H2S synthesis, with DL-propargylglycine (PPG), and acute inhibition of NO-synthase with nonspecific L-NG-nitro arginine methyl ester (L-NAME), and vasoactive responses of the thoracic aorta (TA) and mesenteric artery (MA) were investigated after acute incubation with PPG. We confirmed that chronic H2S deficiency had no effect on blood pressure, heart trophycity, noradrenaline, and H2S donor vasoactive responses but induced renal hypertrophy and a decrease in acetylcholine-induced hypotensive and L-NAME-induced hypertensive responses. Acute H2S deficiency led to an increase in basal tone (MA) or active tone (TA), whereas endothelium-dependent vasorelaxation remained unaffected. Long-term administration of PPG revealed a role of endogenous H2S in the bioavailability of endothelial NO in peripheral arteries. When both H2S and NO were lacking, the activation of H2S-independent compensatory mechanisms plays an important role in maintaining the vasodilator responses of the cardiovascular system.
A coleção Brazil’s Popular Groups: o “artesanato” de uma narrativa
Authors: Bettamio Rafaella Lúcia de Azevedo Fereira 
Published: February 2022

A vultosa coleção microfilmada Brazil’s Popular Groups (BPG) foi organizada por mais de 30 anos pelo escritório de representação da Library of Congress (LOC) do Rio de Janeiro. A partir da coleta de materiais efêmeros – em sua maioria, pôsteres, panfletos e períodicos de pequena tiragem e curta duração –, a coleção apresenta cerca de 60 anos de história de um variado grupo de movimentos sociais brasileiros . Partindo do entendimento de que coleções resultam de processos de construção narrativa do colecionador, este artigo pretende dar visibilidade às distintas temporalidades e subjetividades que presidiram a historicidade e a construção narrativa da Brazil's Popular Groups, e, por fim, elucidar como ocorrem tais processos e de que forma as narrativas deles resultantes são enunciadas por coleções com dimensão pública.

Abstract
Low childhood socioeconomic status (SES) is associated with increased risk for psychopathology, in part because of heightened exposure to environmental adversity. Adverse experiences can be characterized along dimensions, including threat and deprivation, that contribute to psychopathology via distinct mechanisms. The current study investigated a neural mechanism through which threat and deprivation may contribute to socioeconomic disparities in psychopathology. Participants were 177 youths (83 girls) aged 10–13 years recruited from a cohort followed since the age of 3 years. SES was assessed using the income-to-needs ratio at the age of 3 years. At the age of 10–13 years, retrospective and current exposure to adverse experiences and symptoms of psychopathology were assessed. At this same time point, participants also completed a face processing task (passive viewing of fearful and neutral faces) during an fMRI scan. Lower childhood SES was associated with greater exposure to threat and deprivation experiences. Both threat and deprivation were associated with higher depression symptoms, whereas threat experiences were uniquely linked to posttraumatic stress disorder symptoms. Greater exposure to threat, but not deprivation, was associated with higher activation in dorsomedial pFC to fearful compared with neutral faces. The dorsomedial pFC is a hub of the default mode network thought to be involved in internally directed attention and cognition. Experiences of threat, but not deprivation, are associated with greater engagement of this region in response to threat cues. Threat-related adversity contributes to socioeconomic disparities in adolescent psychopathology through distinct mechanisms from deprivation.
Electrophysiological Evidence for the Suppression of Highly Salient Distractors
Authors: Stilwell Brad T. , Egeth Howard , Gaspelin Nicholas 
Published: February 2022

Abstract
There has been a longstanding debate as to whether salient stimuli have the power to involuntarily capture attention. As a potential resolution to this debate, the signal suppression hypothesis proposes that salient items generate a bottom–up signal that automatically attracts attention, but that salient items can be suppressed by top–down mechanisms to prevent attentional capture. Despite much support, the signal suppression hypothesis has been challenged on the grounds that many prior studies may have used color singletons with relatively low salience that are too weak to capture attention. The current study addressed this by using previous methods to study suppression but increased the set size to improve the relative salience of the color singletons. To assess whether salient distractors captured attention, electrophysiological markers of attentional allocation (the N2pc component) and suppression (the PD component) were measured. The results provided no evidence of attentional capture, but instead indicated suppression of the highly salient singleton distractors, as indexed by the PD component. This suppression occurred even though a computational model of saliency confirmed that the color singleton was highly salient. Altogether, this supports the signal suppression hypothesis and is inconsistent with stimulus-driven models of attentional capture.
The Role of Seasonality and the ENSO Mode in Central and East Pacific ENSO Growth and Evolution

Published: February 2022

Abstract
A cyclostationary linear inverse model (CSLIM) is used to investigate the seasonal growth of tropical Pacific Ocean El Niño–Southern Oscillation (ENSO) events with canonical, central Pacific (CP), or eastern Pacific (EP) sea surface temperature (SST) characteristics. Analysis shows that all types of ENSO events experience maximum growth toward final states occurring in November and December. ENSO events with EP characteristics also experience growth into May and June, but CP events do not. A single dominant “ENSO mode,” growing from an equatorial heat content anomaly into a characteristic ENSO-type SST pattern in about 9 months (consistent with the delayed/recharge oscillator model of ENSO), is essential for the predictable development of all ENSO events. Notably, its seasonality is responsible for the late-calendar-year maximum in ENSO amplification. However, this ENSO mode alone does not capture the observed growth and evolution of diverse ENSO events, which additionally involve the seasonal evolution of other nonorthogonal Floquet modes. EP event growth occurs when the ENSO mode is initially “covered up” in combination with other Floquet modes. The ENSO mode’s slow seasonal evolution allows it to emerge while the other modes rapidly evolve and/or decay, leading to strongly amplifying and more predictable EP events. CP events develop when the initial state has a substantial contribution from Floquet modes with meridional mode–like SST structures. Thus, while nearly all ENSO events involve the seasonally varying ENSO-mode dynamics, the diversity and predictability of ENSO events cannot be understood without identifying contributions from the remaining Floquet modes.

Significance Statement
The purpose of this study is to identify structures that lead to seasonal growth of diverse types of El Niño–Southern Oscillation (ENSO) events. An important contribution from this study is that it uses an observationally constrained, empirically derived seasonal model. We find that processes affecting the evolution of diverse ENSO events are strongly seasonally dependent. ENSO events with eastern equatorial Pacific sea surface temperature (SST) characteristics are closely related to a single “ENSO mode” that resembles theoretical models of ENSO variability. ENSO events that have central equatorial Pacific SST characteristics include contributions from additional “meridional mode” structures that evolve via different physical processes. These findings are an important step in evaluating the seasonal predictability of ENSO diversity.
Symptomatic Lingual Thyroglossal Duct Cyst in Children: A Laryngomalacia Phenotype
Authors: Shumrick Christopher M. , Calder Alyssa N. , Vecchiotti Mark A. , Scott Andrew R. 
Published: February 2022

Objectives: Patients with lingual thyroglossal duct cyst (TGDC) can present as symptomatic with obstructive airway and feeding difficulties. Methods: We present 3 cases of symptomatic lingual TGDC. Results: All 3 patients were diagnosed with laryngomalacia and underwent further concurrent or delayed airway intervention, in addition to cyst removal. Conclusions: We reason that there is a phenotype of laryngomalacia in the symptomatic lingual thyroglossal duct cyst patients who present with symptoms due to disruption in laryngeal anatomy rather than the cyst itself causing obstructive symptoms. Distinguishing this phenotype, especially in comparison to other pathologies such as vallecular cysts, may better allow for planning of concurrent or delayed airway procedures and overall counseling of parents.
Perceived social support and depressive symptoms during the COVID-19 pandemic: A nationally-representative study
Authors: Ju Yeong Jun , Kim Woorim , Lee Soon Young 
Published: February 2022

Background: The COVID-19 pandemic and the associated containment policies have led to negative mental health consequences in the general population. Aims: This study investigated the association between perceived social support and depressive symptoms in Korea. Methods: Data from the Korea Community Health Survey conducted from August to November 2020 was used for this cross-sectional study. Depressive symptoms were measured using the Patient Health Questionnaire-9 (PHQ-9) and perceived social support was assessed based on the number of contacts that participants had identified as being available in case participants needed isolation due to COVID-19 exposure. This study included the general adult populations aged 19 years and older. The relationship between the perceived social support and depressive symptoms was analyzed using multivariable liner regression analysis. Subgroup analysis was conducted based on income. Results: Analysis of the data obtained from 225,453 participants indicated that PHQ-9 scores were highest in the group with ‘no’ perceived social support, followed by ‘low’, ‘middle’, and ‘high’ perceived levels of social support. Compared to individuals with ‘high’ perceived social support, those with ‘middle’ (β: .10, p-value <.001), ‘low (β: .07, p-value .010), and ‘no’ (β: .34, p-value <.001) perceived levels of social support showed poorer depression scores. The magnitude of the relationship found was particularly strong in the low-income group. Conclusions: During the COVID-19 pandemic, individuals’ depression scores varied according to their perceived level of social support. Strategies that address the need of vulnerable individuals are required to reduce the potentially negative mental health consequences of the pandemic.
Attachment orientation and depression: A moderated mediation model of self-silencing and gender differences
Authors: Emran Ashti , Iqbal Naved , Dar Kaiser Ahmad 
Published: February 2022

Background: While the effect of insecure attachment on depression is well established, findings pertaining to the relationship between specific attachment dimensions (anxious and avoidant) and depression are inconsistent. The role of interpersonal factors underlying this effect has been little explored. ‘Silencing the Self’, a socio-cognitive construct may provide important insights as a mediating pathway from insecure attachment to depression and help resolve the inconsistencies. Aims: The present study explored the mediating effect of self-silencing and the role of gender as a moderator in the relation between insecure attachment orientation (i.e. avoidant and anxious) and depressive symptoms. Method: Data was collected via an online survey, from 121 adults who were in a relationship. The participants were asked to complete three self-report questionnaires, assessing attachment orientation, silencing the self and depressive symptoms. Moderated mediation analysis was performed using conditional process analysis. Results: The results indicated that the effect of both insecure attachment dimensions on depressive symptoms was mediated by silencing the self. In addition, gender moderated the association between insecure attachment and self-silencing. Conclusions: This study adds to the literature on mediating pathways between insecure attachment and depression, and provides a new perspective for therapeutic interventions in the context of depression. It indicates that professionals should focus on current social context and relational schemas of individuals with an insecure attachment, especially women, while treating cases of depression in clinical settings.
A Mother and Her Daughters: Jewish Teachers and the Fight against Apartheid
Authors: Wieder Alan 
Published: February 2022

Background Before 1999, there was little research on teachers and apartheid aside from some biographical sketches. “A Mother and Her Daughters” is part of an ongoing oral history project of teachers who fought apartheid. It is contextualized through the literature on Jews and apartheid in South Africa and joins the growing literature on teachers in the country. Purpose: The article describes and analyzes the lives of three Jewish women, a mother and two of her daughters, who as teachers challenged the apartheid regime in their communities and in their schools. The elder teacher taught in a Jewish day school and brought the issues of apartheid to Jewish studies, and her daughters taught in black schools during the struggle years. The lives of the three women portrayed are analyzed within the context of the political divide among Jewish South Africans during apartheid. Setting and Participants “A Mother and Her Daughters” is part of an oral history project in South Africa with over 200 teachers from each of the apartheid government designated ethnic groups: Africans, coloureds, Indians, and whites. Research Design I have spent the last six years working on an oral history project with teachers who fought apartheid. The first people that I interviewed were referred to me by university colleagues in South Africa. As the project continued, I spoke to teachers who often provided me with lists of other teachers. The methodological process is what ethnographers define as network sampling, or snowball sampling. As I have argued elsewhere, and with a sensitivity to issues of memory, culture, class, race, ethnicity, gender, and power and their relationship to oral history, I view my work as testimony as oral history. While most oral historians conduct research by identifying informants and conducting interviews, testimony as oral history recognizes that individuals need to speak—to testify and provide witness to their lives. Conclusions The women portrayed in the article joined many other South Africans on the ground to fight the apartheid regime. The lives of the Silbert women are important because they went against the norm of their own Jewish community, and white South Africa, to work for the end of apartheid and for a democratic South Africa. They went against the grain of most South African teachers and represent what scholar and politico I. B. Tabata called “teachers with the fighting spirit.” Marlene, Beth, and Patti Silbert combined pedagogy and politics to fight apartheid. Their stories are significant because with other “teachers with the fighting spirit,” they were part of derailing apartheid and facilitating the election of Nelson Mandela in 1994. In addition, individually and collectively, the stories of the Silbert women offer possibilities of education for democracy—in South Africa and throughout the world.
Learning to Teach as Assisted Performance
Authors: Mewborn Denise S. , Stinson David W. 
Published: February 2022

Background Although preservice teachers bring well-established views of teaching to their teacher education programs, Tabachnick and Zeichner (1984) claimed that it is possible to amend preservice teachers’ views. They portrayed the learning of teachers as a negotiated and interactive process rather than as one that is predetermined by teachers’ prior experiences. Feiman-Nemser (2001) suggested that having preservice teachers examine their beliefs in light of images of good teaching should be one of the central tasks of preservice teacher education. Purpose The study reported in this manuscript was conducted in an effort to document and examine the interplay between novice teachers’ personal theories, their mathematics education coursework, and their field experiences. Research Design Using all four methods of data collection attributed to ethnographic research (Eisenhart, 1988)—artifact collection, participant observation, ethnographic interviewing, and researcher introspection—this interpretivist study (Zeichner & Gore, 1990) attempted to document and examine the learning of seven preservice elementary teachers as reflected in their mathematics methods coursework and subsequent field experiences. Findings This manuscript describes three tasks from the mathematics methods course—critiquing an essay written by a teacher as she reflected on her teaching practice; working one-on-one with a child in mathematics for an extended period of time; and observing an experienced teacher teach an elementary mathematics lesson—that provided preservice elementary school teachers with opportunities to learn and grow as teachers by making their beliefs explicit and then reflecting on their beliefs and linking these beliefs to the practice of teaching mathematics. The tasks described engaged the preservice teachers in examining beliefs critically in relation to visions of good teaching, developing an understanding of learners and learning, and developing the tools and dispositions to study teaching. Conclusions While an analysis of the data showed evidence that the preservice teachers became aware of their beliefs, reflected on their beliefs, and began to change their beliefs, the purpose of this manuscript is not to claim that the teachers changed for the good and that this change was enduring. Rather, the goal is to illuminate the tasks, provide the preservice teachers’ responses and reactions to the tasks, and to argue that these tasks constitute a form of learning to teach mathematics through assisted performance.
