Environmental sustainability criteria in the multi-oriented shipbuilding industry in Indonesia Azhar, Ali; Harahab, Nuddin; Putra, Fadillah; Kurniawan, Andi Preliminary studies have highlighted the potential of Indonesia’s geographical, suprastructural, and infrastructural conditions to develop a strong shipbuilding industry, which is crucial for the success of the world maritime axis program and sea toll. However, despite high expectations, the industry faces challenges that threaten business sustainability, leading to bankruptcies. To assess business sustainability, it is essential to establish criteria and sub-criteria, which previous studies have overlooked, focusing only on technical and economic factors. Therefore, this research generally aims to develop and analyze environmentally friendly sustainable criteria in the multi-oriented shipyard industry so that it develops in accordance with the vision, mission, goals and strategies. The criteria development process involves identifying and reviewing relevant articles, classifying and refining the criteria, conducting expert validity testing, Pearson Product Moment validity testing, and reliability testing using the Alpha (Cronbach) method. The expert validity testing indicates that ‘people’ received the highest average score of 4.67 among the criteria, and ‘infrastructure’ scored the highest in the sub-criteria, with a score of 4.75. The validity testing with the Pearson Product Moment method demonstrates that the criteria and sub-criteria are valid and the reliability of 32 sub-criteria indicating their influence on promoting multi-oriented and environmentally sustainable shipbuilding industries

Lev el of c reactive protein (CRP) among cardiovascular disease patients with chronic periodontitis in Cardiovascular Department of Dr. Soetomo National Hospital Surabaya Wedarti, Yoifah Rizka Background: Periodontitis is a local inflammatory process mediating destruction of periodontal tissues triggered by bacterial insult. However, this disease is also characterized by systemic inflammatory host responses that may contribute, in part, to the recently reported higher risk for cardiovascular disease (CVD) among patients with periodontitis. Moderate elevation of C-reactive protein (CRP) has been found to be a predictor of increased risk for CVD. Elevated CRP levels in periodontal patients have been reported by several groups. In this study, we examined whether CRP plasma levels are increased in periodontitis and if there is a relation to severity of periodontal disease. Methods: CRP serum levels were assessed using reagen Immulite C-Reactive Protein ® / Immulite ® 1000 high-sensitivity CRP as a solid-phase, chemiluminescent immunometric assay in 100 subjects which diagnosed cardiovascular disease with chronic periodontitis. Periodontal Disease Index (PDI) were measured by clinical attachment loss, probing depths, and gingiva recession at six selection teeth : 16, 21, 24, 36, 41,44 known as Ramfjord teeth. Results: The measurement of Periodontal Disease Index (PDI) in 100 subjects with Cardiovascular Disease are Mild periodontitis (6,1%), Moderate periodontitis (70,4%), Severe periodontitis (23,5%) and only 2% with normal periodontal tissue. Increases in CRP levels were observed in these subjects. Subjects with high levels of clinical attachment loss (Severe periodontitis) had significantly higher mean of CRP levels (7,522 ± 0,3580 mg/L), moderate periodontitis are (5,284 ± 0,3138 mg/L) CRP levels and (2,017 ± 0,3656 mg/L) CRP levels for mild periodontitis Conclusions: The positive correlation between CRP and periodontal disease might be a possible underlying pathway in the association between periodontal disease which a chronic inflammation as one of risk factor for Cardiovascular Disease in these patients.

Access to Maternal Healthcare Services during the Pandemic in Specialized Hospitals for Mother and Child

2021-11-22T07:49:10Z

Access to Maternal Healthcare Services during the Pandemic in Specialized Hospitals for Mother and Child Pagatiku, Abigael S.; Vitariani, Tentia; Shihata, Ibrahim; Ariyanto, Bambang This research aims to see how is access to maternal services in the pandemic era. Maternal patients with COVID-19 without symptoms (co-incidence) can only access a limited number of health facilities and make it more challenging to access healthcare services. Whereas previously, with the integrated referral system, it was easier for patients to access healthcare services. All childbirth during the pandemic takes place in a Healthcare Facility. Pregnant women with suspected, probable, and confirmed COVID-19 would have childbirth at a COVID-19 referral hospital. Based on our study results, as the conclusion, patients with an integrated referral system will be easy to get access to healthcare services. Maternal patients with confirmed COVID-19 without any symptoms have limited access to the health facilities, making access to healthcare services is not easy as before. Easy access to healthcare services is a patient’s right, including a pregnant women’s right with confirmed COVID-19. Therefore, the government needs to increase the number of COVID-19 Referral Hospital. To provide healthcare services, the Specialized Hospital for Mother and Child can handle the normal childbirth of COVID-19 patients. It is necessary to make regulations on the childbirth of COVID-19 patients at the Specialized Hospital for Mother and Child.

2021-10-01T11:52:35Z

Dengue Lurks During Coronavirus Disease-19 Pandemic in Indonesia: A Narrative Review Diarsvitri, Wienta; Budiarti, Retno; Nugraheni, Pramita Anindya; Ilmawan, M. Fathi; Biutifasari, Verna BACKGROUND: Most attention and healthcare resources in Indonesia have been geared toward battling the coronavirus (CoV) disease (COVID)-19 pandemic, and less overture has been given to the looming risks of dengue that has been endemic in many areas of Indonesia. Despite related constraints, the Primary Health Cares (PHC) in Indonesia plays an important role in the face of emergency situations. AIM: This study aimed to review the dengue and COVID-19 infection, clinical manifestations in children and adults, clinical pathology findings, as well as the prevention strategies that could be applied in PHC. METHODS: This study is a narrative review based on the research articles and reports that were published between 2010 and 2020. A total of 70 articles and reports were obtained and after careful consideration, 58 articles and reports were used as references of this study. RESULTS: Both dengue virus (DENV) and severe acute respiratory syndrome-CoV (SARS-CoV-2) share the similarity of antigenic structure, common symptoms, and laboratory findings. The immune response in SARS-CoV-2 may cause a cytokine storm, which can increase vascular permeability and organ damage. Secondary infection of DENV with different strains may allow the occurrence of antibody-dependent enhancement. The cross-reactions between SARS-CoV-2 antibodies and DENV antigens may cause false positive on rapid dengue infection serological tests. CONCLUSION: PHC as the front line of health services has a fundamental role in the crisis situation. The prevention and control of DENV and SARS-CoV-2 infections are based on the mode of transmission and need compliance to the related health protocols

2021-09-11T01:19:56Z

The Astaxanthin Effect On The Differential Count Of Inflamatory Cell In Nickel Allergy Balb/c Mice Model Andriani, Dwi Nickel is a material that commonly used in dentistry, but in some individuals, it can cause type IV delayed-type hypersensitivity (DTH) reaction. In this case, DTH reaction pathway involves T cell helper 1 (Th1) activation that stimulates macrophages to release pro-inflammatory cytokine. Meanwhile, astaxanthin (AST) is carotenoid from red algae that has an anti-inflammatory effect by inhibiting inflammatory mediators. Hematology evaluation is one of the evaluation methods for allergies. This investigation aimed to determine the effect of astaxanthin supplementation on the differential count of inflammatory cells in nickel allergy of mice model. Sixteen Balb/C mice were randomly divided into 4 groups: normal group (N), without therapy group (NA), Astaxanthin 12 mg treatment group (Ast12) and Astaxanthin 6 mg treatment group (Ast6). All groups were given an injection of Nickel(II) chloride (NiCl2 ), Complete Freud’s Adjuvant (CFA), and Incomplete Freud’s Adjuvant (IFA) to obtain the nickel allergy model. Analysis of differential count in an inflammatory cell (neutrophil, lymphocyte, monocyte and eosinophil) performed by utilizing flow cytometry, then, the data were analyzed using Univariate Analysis (p<0.05). As the result, there were no any significant differences between groups for neutrophil and lymphocyte showed by One-Way ANOVA test. Kruskal-Wallis test for eosinophil and monocyte also exhibited no significant difference. In sum, astaxanthin supplementation did not have any effect on the differential count of inflammatory cells (neutrophil, lymphocyte, monocyte and eosinophil) in nickel allergy mice model compared to the normal and without therapy ones
