Ketika warga negara berada dalam bahaya, negara harus turun tangan untuk memastikan keselamatan mereka di dalam dan luar negeri. Sudah bukan berita yang mengejutkan lagi bahwa Indonesia memiliki populasi pekerja asing yang cukup besar dari Indonesia, sehingga saat ini perlindungan terhadap mereka masih perlu dioptimalisasikan terkait pelaksanaannya. Kehadiran instrumen-instrumen hukum belum diimplementasikan sebagaimana yang tertulis. Perbedaan nilai-nilai antara negara Indonesia dengan yang lain bisa menjadi hambatan dalam penanganan konflik yang dihadapi pekerja migran Indonesia. Dalam mengatasi konflik antarnegara, maka diperlukan untuk berpedoman pada sumber-sumber hukum internasional dan tidak hanya berpedoman pada salah satu hukum nasional suatu negara yang berkonflik. Penyelesaian konflik internasional umumnya dilakukan oleh perwakilan diplomatik yang ditugaskan ke suatu negara. Kajian mengenai perwakilan diplomatik ada dalam Hukum Diplomatik yang juga termasuk ke dalam kajian Hukum Internasional.

Cajanus cajan: a promissory high-nitrogen fixing cover crop for Uruguay
Authors: Berriel Verónica , Perdomo Carlos H. 
Published: June 2023

Cover crops can increase agricultural sustainability by protecting soil from erosion, increasing biodiversity, and symbiotically incorporating fixed nitrogen (N) into the soil. Nowadays, however, in Uruguay mostly grasses are planted in autumn to protect the soil from erosion. Another option is to study tropical legumes’ performance as cover crops, which can fix substantial amounts of nitrogen in short growing periods, thereby bridging the knowledge gap in Uruguayan agriculture. The main objective was to evaluate and compare the performance of six tropical legumes (Crotalaria juncea, Crotalaria spectabilis, Crotalaria ochroleuca, Cajanus cajan, Dolichos lablab, Mucuna pruriens) and the temperate legume Glycine max. The evaluation focused on aboveground biomass and the N mass derived from fixation (NmdFix), as well as other attributes; three field experiments were conducted on a southern Uruguay farm during the summers of 2017, 2018, and 2019. The growing cycle lengths for the cover crops in 2017, 2018, and 2019 were 117, 130, and 90 days, respectively. The results showed that when planting was done at late December (2017 and 2018 growing cycles), the species with the highest mean biomass yield were Crotalaria juncea (two year average 12.0 Mg ha-1) and Cajanus cajan (11.0 Mg ha-1), but Cajanus cajan (149 kg ha-1) more than doubled the NmdFix mass of Crotalaria juncea (57 kg ha-1). In 2018 biomass yields were much higher than in 2017, with Glycine max (20.0 Mg ha-1) yielding at a similar level to Crotalaria juncea and Cajanus cajan (20.5 and 18.7 Mg ha-1, respectively). Amounts of NmdFix, however, were much higher in Glycine max and Cajanus cajan (263 and 253 kg N ha-1, respectively), than in Crotalaria juncea (91 kg N ha-1). In 2019 planting had to be delayed until early February and only Glycine max maintained acceptable biomass and NmdFix levels. In conclusion, based on its fixing N potential, for late December sowings Cajanus cajan and Glycine max would be the most promising species for cover crop use, while for late January or early February sowings, only Glycine max would an option because the tropical species seriously impaired their productivity when grew longer into the cooler autumn temperatures.

Introduction: Plenty of biomaterials have been studied for their application in skin tissue engineering. Currently, gelatin-hydrogel is used to support three-dimensional (3D) skin in vitro models. However, mimicking the human body conditions and properties remains a challenge and gelatin-hydrogels have low mechanical properties and undergo rapid degradation rendering them not suitable for 3D in vitro cell culture. Nevertheless, changing the concentration of hydrogels could overcome this issue. Thus, we aim to investigate the potential of gelatin hydrogel with different concentrations crosslinked with genipin to promote human epidermal keratinocytes and human dermal fibroblasts culture to develop a 3D-in vitro skin model replacing animal models.Methods: Briefly, the composite gelatin hydrogels were fabricated using different concentrations as follows 3%, 5%, 8%, and 10% crosslinked with 0.1% genipin or non-crosslinked. Both physical and chemical properties were evaluated.Results and discussion: The crosslinked scaffolds showed better properties, including porosity and hydrophilicity, and genipin was found to enhance the physical properties. Furthermore, no alteration was prominent in both formulations of CL_GEL 5% and CL_GEL8% after genipin modification. The biocompatibility assays showed that all groups promoted cell attachment, cell viability, and cell migration except for the CL_GEL10% group. The CL_GEL5% and CL_GEL8% groups were selected to develop a bi-layer 3D-in vitro skin model. The immunohistochemistry (IHC) and hematoxylin and eosin staining (H&amp;E) were performed on day 7, 14, and 21 to evaluate the reepithelization of the skin constructs. However, despite satisfactory biocompatibility properties, neither of the selected formulations, CL_GEL 5% and CL_GEL 8%, proved adequate for creating a bi-layer 3D in-vitro skin model. While this study provides valuable insights into the potential of gelatin hydrogels, further research is needed to address the challenges associated with their use in developing 3D skin models for testing and biomedical applications.

BackgroundThe pathophysiology of atherosclerotic plaque formation and its vulnerability seem to differ between genders due to contrasting risk profiles and sex hormones, however this process is still insufficiently understood. The aim of the study was to compare the differences between sexes regarding the optical coherence tomography (OCT), intravascular ultrasound (IVUS) and fractional flow reserve (FFR)-derived coronary plaque indices.MethodsIn this single-center multimodality imaging study patients with intermediate grade coronary stenoses identified in coronary angiogram (CAG) were evaluated using OCT, IVUS and FFR. Stenoses were considered significant when the FFR value was ≤0.8. Minimal lumen area (MLA), was analyzed by OCT in addition to plaque stratification into fibrotic, calcific, lipidic and thin-cap fibroatheroma (TCFA). IVUS was used for evaluation of lumen-, plaque- and vessel volume, as well as plaque burden.ResultsA total of 112 patients (88 men and 24 women) with chronic coronary syndromes (CCS), who underwent CAG were enrolled. No significant differences in baseline characteristics were present between the study groups. The mean FFR was 0.76 (0.73–0.86) in women and 0.78 ± 0.12 in men (p = 0.695). OCT evaluation showed a higher prevalence of calcific plaques among women than men p = 0.002 whereas lipid plaques were more frequent in men (p = 0.04). No significant differences regarding minimal lumen diameter and minimal lumen area were found between the sexes. In IVUS analysis women presented with significantly smaller vessel area, plaque area, plaque volume, vessel volume (11.1 ± 3.3 mm2 vs. 15.0 ± 4.6 mm2p = 0.001, 6.04 ± 1.7 mm2 vs. 9.24 ± 2.89 mm2p &lt; 0.001, 59.8 ± 35.2 mm3 vs. 96.3 (52.5–159.1) mm3p = 0.005, 106.9 ± 59.8 mm3 vs. 153.3 (103–253.4) mm3p = 0.015 respectively). At MLA site plaque burden was significantly greater for men than women (61.50 ± 7.7% vs. 55.5 ± 8.0% p = 0.005). Survival did not differ significantly between women and men (94.6 ± 41.9 months and 103.51 ± 36.7 months respectively; p = 0.187).ConclusionThe presented study did not demonstrate significant differences in FFR values between women and men, yet a higher prevalence of calcific plaques by OCT and lower plaque burden at the MLA site by IVUS was found in women vs. men.

AimsDiagnosis of myocardial fibrosis is commonly performed with late gadolinium contrast-enhanced (CE) cardiac magnetic resonance (CMR), which might be contraindicated or unavailable. Coronary computed tomography (CCT) is emerging as an alternative to CMR. We sought to evaluate whether a deep learning (DL) model could allow identification of myocardial fibrosis from routine early CE-CCT images.Methods and resultsFifty consecutive patients with known left ventricular (LV) dysfunction (LVD) underwent both CE-CMR and (early and late) CE-CCT. According to the CE-CMR patterns, patients were classified as ischemic (n = 15, 30%) or non-ischemic (n = 35, 70%) LVD. Delayed enhancement regions were manually traced on late CE-CCT using CE-CMR as reference. On early CE-CCT images, the myocardial sectors were extracted according to AHA 16-segment model and labeled as with scar or not, based on the late CE-CCT manual tracing. A DL model was developed to classify each segment. A total of 44,187 LV segments were analyzed, resulting in accuracy of 71% and area under the ROC curve of 76% (95% CI: 72%−81%), while, with the bull’s eye segmental comparison of CE-CMR and respective early CE-CCT findings, an 89% agreement was achieved.ConclusionsDL on early CE-CCT acquisition may allow detection of LV sectors affected with myocardial fibrosis, thus without additional contrast-agent administration or radiational dose. Such tool might reduce the user interaction and visual inspection with benefit in both efforts and time.

IntroductionRecently published studies suggest that percutaneous coronary intervention (PCI) has no significant impact on outcomes in patients with heart failure and stable coronary artery disease. The use of percutaneous mechanical circulatory support is growing, but its value is still uncertain. If large areas of viable myocardium are ischemic, the benefit from revascularization should be evident. In such instances, we should strive for complete revascularization. The use of mechanical circulatory support in such cases is vital because it provides hemodynamic stability throughout the complex procedure.Case reportWe present a case of a 53-year-old male heart transplant candidate with type 1 diabetes mellitus, initially considered unsuitable for revascularization and qualified for heart transplantation, transferred to our center due to acute decompensated heart failure. At this time, the patient had temporary contraindications for heart transplantation. As the patient was considered no-option, we have decided to reassess the possibility of revascularization. The heart team opted for a high-risk mechanically supported PCI with the aim of complete revascularization. A complex multivessel PCI was performed with optimal effect. The patient was weaned off dobutamine on the second day post-PCI. Four months post-discharge, he remains stable, is in NYHA II class, and has no chest pain. Control echocardiography showed improved ejection fraction. The patient is not a heart transplant candidate anymore.ConclusionsThis case report shows that we must strive for revascularization in select heart failure cases. The outcome of this patient suggests that heart transplant candidates with potentially viable myocardium should be considered for revascularization, especially as the shortage of donors persists. In the most complex coronary anatomy and severe heart failure, mechanical support in the procedure might be essential.

IntroductionCentral to public health practice is mindfulness and intentionality toward achieving social justice and health equity. However, there is limited literature published on how educators are integrating these concepts into their curricular, pedagogical and instructional efforts. The goal of this study was to leverage the pluralistic views, social identities, and demographics within the classroom to explore the effects of introducing a Global Health Book Club (GHBC) assignment focused on identity of culture, equity, and power. We also sought to explore the use of first-account narratives illustrating the human experience as an instructional strategy to cultivate an empathic understanding of global health threats, while fostering critical consciousness toward one’s positionality within macro-level contexts. Finally, students were encouraged to reflect on their lived cultural experiences and engage in open and authentic dialogue with their peers.MethodsWe implemented a four-week GHBC assignment within an undergraduate global public health course. At the conclusion of the GHBC, students engaged in a reflective Individual Analysis Paper, which captured students’ perspectives on their cultural values and traditions, how these views shaped their understanding of their book, and evaluate whether their global perspective had changed as a result of the assignment. Thirty-one students consented to have their Individual Analysis Paper downloaded and de-identified for analysis. Student responses were analyzed using inductive thematic analysis procedures.ResultsThrough our analysis, six themes, with several coinciding categories, were identified as salient. The themes include Demonstrated Empathy, Personal Reflection and Growth, Personally Inspired, Immersive Learning Experience, Broadened Perspective, and Provoked Emotion.DiscussionOur findings support that a GHBC assignment is a viable and effective mechanism for engaging students in critical reflection, critical motivation and critical action. In cultivating a learning environment that promotes student-centered learning and active participation, students exemplified agency in their own learning. This work can serve as an exemplary model for other public health educators to engage students in reflective-based assignments regarding their positionality and critical consciousness. By utilizing frameworks conceived out of antiracism, diversity, equity, and inclusion, our work presents an innovative activity in engaging students in decolonization efforts within global public health practice.

IntroductionStrengthening the self-confidence of future professionals can help them achieve professional goals with a likelihood of being able to achieve them in the future. The objective was to determine whether self-esteem, depression, and life satisfaction influence the future expectations of Peruvian university students.MethodsA total of 708 university students participated (64.8% were female, mean age = 21.49; SD = 4.83). The Rosenberg Self-Esteem Scale, the Patient Health Questionnaire-2, the Life Satisfaction Scale, and the Adolescent Future Expectations Scale were used. Structural equation modeling was employed to test the impact of selfesteem, depression, and life satisfaction on future expectations.ResultsThe model relating the study variables demonstrated an adequate fit (p &lt; 0.001, CFI = 0.940, RMSEA = 0.073), confirming the relationship between self-esteem (β = 0.33, p &lt; 0.001), life satisfaction (β = 0.28, p &lt; 0.001), and depression (β =  −0.14, p &lt; 0.010.) with future expectations. This model explained 36% of future expectations.DiscussionIn conclusion, future expectations may be affected by low levels of self-esteem and life satisfaction and high levels of depression.
