Indonesian stakeholders' perspectives on warning signs and beliefs about suicide

The suicide rate in Indonesia is considered low among Asian countries, but the underreporting rate is at a staggering 303%, and the latest reports suggest an increase in suicidal behaviour, particularly among young people. As a multicultural country, Indonesia has a complex system of beliefs about suicide. Thus, various aspects specific to Indonesia must be considered in understanding and preventing suicide. This paper explores Indonesian stakeholders’ perspectives through semi-structured interviews and focus group discussions. A total of 9 participants were individually interviewed, and 42 were involved in focus group discussions. They were mainly people with lived experiences of suicide. The other stakeholders were Indonesian experts who have experience in dealing with suicidal behaviour, helping people with a lived experience of suicide, or were involved in suicide prevention. Indonesian stakeholders highlighted various general and contextualised aspects concerning suicide. These aspects included a wide range of cultural beliefs and culturally specific warning signs, which included “bingung” (confusion) and longing for deceased persons. Other cultural beliefs such as viewing suicide as infectious, unpreventable, and guided by ancient spirits, and as an honourable act in some circumstances, also emerged. These findings can inform suicide prevention programs, including suicide prevention guidelines for Indonesia

Suicide first aid guidelines for Indonesia: a Delphi consensus study

Background: The concept that "suicide is preventable" is fairly recent in Indonesia. Suicide prevention training is also new for community leaders and laypeople. On the other side, in a collectivistic society like Indonesia, community leaders, neighbours, and friends are essential parts of someone's life. Therefore, guidelines to assist first aiders in preventing suicide is urgently needed. Aim: This study aimed to develop guidelines to recognise key warning signs and provide first aid support to Indonesians at potential immediate risk for suicide. Methods: The guidelines was developed through three steps: (i) systematic literature review; (ii) focus group discussions and interviews; and (iii) expert consensus using the Delphi approach. These steps were taken to ensure that the final guidelines reflected the cultural beliefs and norms of the Indonesian context. Results: Three rounds of Delphi resulted in 460 accepted items out of 539 items generated from the literature search and group and individual interviews. Some key differences with other countries where similar studies were carried out were highlighted. Conclusions: This study emphasised the need for gatekeeper training as the ideal way of educating community members on the guidelines

R-mode oscillations and rocket effect in rotating superfluid neutron stars. I. Formalism

We derive the hydrodynamical equations of r-mode oscillations in neutron stars in presence of a novel damping mechanism related to particle number changing processes. The change in the number densities of the various species leads to new dissipative terms in the equations which are responsible of the {\it rocket effect}. We employ a two-fluid model, with one fluid consisting of the charged components, while the second fluid consists of superfluid neutrons. We consider two different kind of r-mode oscillations, one associated with comoving displacements, and the second one associated with countermoving, out of phase, displacements.Comment: 10 page

Constraining hypernuclear density functional with Λ\Lambda-hypernuclei and compact stars

We present a simultaneous calculation of heavy single-$\Lambda$ hypernuclei and compact stars containing hypernuclear core within a relativistic density functional theory based on a Lagrangian which includes the hyperon octet and lightest isoscalar-isovector mesons which couple to baryons with density-dependent couplings. The corresponding density functional allows for SU(6) symmetry breaking and mixing in the isoscalar sector, whereby the departures in the $\sigma$-$\Lambda$ and $\sigma$-$\Sigma$ couplings away from their values implied by the SU(3) symmetric model are used to adjust the theory to the laboratory and astronomical data. We fix $\sigma$-$\Lambda$ coupling using the data on the single-$\Lambda$ hypernuclei and derive an upper bound on the $\sigma$-$\Sigma$ from the requirement that the lower bound on the maximum mass of a compact star is $2 M_{\odot}$.Comment: 10 pages, 4 figures, to appear in Phys.

Emotional expression and coping style in female breast cancer.

Background: The study of the relationship of emotional status and tumor etiology has been investigated in order to elaborate a multifactorial model able to provide an answer integrating the different disciplines on cancer. The aim of this work is to investigate the knowledge on the alexithymia construct, exploring the presence of such trait in women affected by mammary carcinoma and analyzing the used coping strategies. The study has also examined personal thoughts related to event control (locus of control). Method: The Toronto Alexithymia Scale, Coping Orientation to Problems Experienced, and Locus of Control questionnaires were administered to a group of 86 women aged 31\u201355 years (mean = 43.7; SD 6.57)\u2014experimental group (N = 44): women with breast cancer diagnosed in the last 6 months; control group (N = 42): women without oncologic pathology, referred at the aforementioned institutions to undergo a breast check-up. Results: According to our hypothesis and literature data, a significant presence of alexithymic subjects (36.4% versus 2.4%; v2 = 20.9; P < 0.0001) and a tendency to adopt coping strategies not focused on the problem were reported among women with mammary carcinoma. This causes incapability to act in order to actively contrast pathology-linked stress or to lower the effects. Conclusion: Our results indicate that the tendency to repress one\u2019s emotions is associated to some general schemes of reaction to stress which, when used in a dysfunctional manner (such as the attempt to ignore how threatening an event is), are maladaptive in the end

Evidence that cells from experimental tumours can activate coagulation factor X.

The procoagulant activity of cells from some experimental tumours isolated in culture or in single-cell suspensions from ascitic fluid was investigated. Cells from Lewis lung carcinoma (primary and metastasis), Ehrlich carcinoma ascites and JW sarcoma ascites were able to shorten markedly the recalcification time of normal, Factor VIII- and Factor VII-deficient but not of Factor X-deficient human plasma. The same cells generated thrombin when mixed with a source of prothrombin and Factor X, absorbed bovine serum (as a source of Factor V), phospholipid and calcium chloride. Thrombin formation was not influenced by the presence of Factor VII. Cells from Sarcoma 180 ascites were completely inactive in both test systems. It is concluded that cells from some experimental tumours have the capacity to activate Coagulation Factor X directly. These findings suggest the existence of an alternative "cellular" pathway in the initiation of blood clotting distinct from both the intrinsic and extrinsic mechanisms

Digital light processing 3D printing of polymerizable ionic liquids towards carbon capture applications

This study presents new 3D printable materials based on ad -hoc synthesized photocurable imidazolium ionic liquids (ILs) with bis(trifluoromethanesulfonyl)imide (NTf 2 ) - as counterion and two different alkyl chain 's structures at the cation, with enhanced CO 2 capture properties. The molecular structure of the synthesized ILs was confirmed through NMR technique and a polymerization study was carried out, by means of photorheological tests and FT-IR analyses, on formulations containing a crosslinking monomer (PEGDA). The study confirmed the good reactivity of the formulations that makes them suitable for digital light processing (DLP) 3D printing technique. Simple membranes were then tested through high pressure CO 2 uptake analysis to estimate their capture efficiency, comparing the results with the standard room temperature ionic liquid (RTIL) counterpart, and evidencing an increase of CO 2 absorption regardless the pressure applied. At last, complex gyroidlike structures incorporating the synthesized ILs were successfully 3D printed, showing the remarkable ability of these materials to be processed with 3D printing technology while maintaining the great CO 2 capture performances of ionic liquids. This preliminary work paves the way for the implementation of "ad -hoc " designs to create filters or devices to enhance the CO 2 capture

Therapeutic strategies against COVID-19

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel coronavirus that mainly affects the upper and lower respiratory tract and is responsible for extremely different degrees of disease, ranging from flu-like symptoms to atypical pneumonia that may evolve to acute respiratory distress syndrome and, ultimately, death. No specific therapy for SARS-CoV-2 has yet been identified, but since the beginning of the outbreak, several pre-existing therapeutics have been reconsidered for the treatment of infected patients. The aim of this article is to discuss current therapeutics against SARS-CoV-2. A literature review was performed using PubMed, collecting data from English-language articles published until June 20th, 2020. Literature analysis showed that with the acquisition of more in-depth knowledge on the characteristics of SARS-CoV-2 and the pathogenesis of the different clinical manifestations, a more rationale use of available drugs has become possible. However, the road to defining which drugs are effective and which schedules of administration must be used to maximize efficacy and minimize adverse events is still very long. To date, it is only clear that no drug can alone cope with all the problems posed by SARS-CoV-2 infection and effective antivirals and inflammatory drugs must be given together to reduce COVID-19 clinical manifestations. Moreover, choice of therapy must always be tailored on clinical manifestations and, when they occur, drugs able to fight coagulopathy and venous thromboembolism that may contribute to respiratory deterioration must be prescribed.
