Published: April 2021

Context: A surgical intervention generally causes physical and psychological strain, which leads to excessive anxiety. The provision of knowledge and patient education during the preoperative period helps to reduce anxiety levels among surgical patients.
Aim: This review conducted to investigate the effect of preoperative education on anxiety levels among patients undergoing surgery or invasive procedure irrespective of general or local anesthesia.
Methods: Searching for related articles performed in four databases (MEDLINE, CINHALE, Trip, and Pub Med) between 2014 to 2018. Out of all searched literature, nine studies retrieved (5 randomized controlled trials, three quasi-experimental studies, and one descriptive study) to be included with a total of 1670 patients. The articles involved in the given review (verbal education, telephone, booklet, and PowerPoint presentation) used different types of educational media.
Results: All the studies where included in this literature review revealed that the most planned and structured preoperative education could reduce anxiety among patients scheduled for surgery or invasive procedure irrespective of general or local anesthesia.
Conclusions: Most of the articles demonstrate the positive effect of planned and structured preoperative educations on anxiety levels, regardless of the types of the media in delivering education to patients.

Abstract
Hypereosinophilic syndrome encompasses a heterogenous group of non-hematologic and hematologic disorders defined as peripheral blood eosinophilia >1500/mm3 persisting more than 6 months and eosinophilic end organ complications1,2. Löeffler endocarditis (LE) is the most common cardiac manifestation of the hypereosinophilic syndrome (HES) and represents an acute form of primary restrictive cardiomyopathy3. We report the case of a 74 years-old woman with symptoms related to congestive heart failure and weight loss. At admission the patient had tachycardia and a grade 2/6 systolic mitral murmur. Laboratory findings revealed eosinophilia, hepatocytolysis syndrome and dyslipidemia. The electrocardiogram (ECG) showed non-specific ST-segment and T wave abnormalities. The echocardiography revealed left ventricular apical thrombus and entrapment of chordae tendineae with restricted motion of mitral leaflets leading to mitral regurgitation. The diagnosis of myocarditis was confirmed by the cardiac magnetic resonance imaging which showed the presence of a left ventricular mass with low signal on steady-state free precession imaging and diffuse circumferential subendocardial late gadolinium enhancement (LGE). When discussing the etiology of the HES the following were taken into consideration: hematologic, reactive or secondary disorders. This case is distinguished by diagnosis in an elderly woman and good response to corticosteroid therapy.

Abstract. In the frame of the EMEP/ACTRIS/COLOSSAL campaign in Milan during winter 2018, equivalent black carbon measurements using the Aethalometer 31 (AE31), the Aethalometer 33 (AE33), and a Multi-Angle Absorption Photometer (MAAP) were carried out together with levoglucosan analyses on 12 h resolved PM2.5 samples collected in parallel. From AE31 and AE33 data, the loading-corrected aerosol attenuation coefficients (bATN) were calculated at seven wavelengths (λ, where λ values are 370, 470, 520, 590, 660, 880, and 950 nm). The aerosol absorption coefficient at 637 nm (babs_MAAP) was determined by MAAP measurements. Furthermore, babs was also measured at four wavelengths (405, 532, 635, 780 nm) on the 12 h resolved PM2.5 samples by a polar photometer (PP_UniMI). After comparing PP_UniMI and MAAP results, we exploited PP_UniMI data to evaluate the filter multiple-scattering enhancement parameter at different wavelengths for AE31 and AE33. We obtained instrument- and wavelength-dependent multiple-scattering enhancement parameters by linear regression of the Aethalometer bATN against the babs measured by PP_UniMI. We found significant dependence of the multiple-scattering enhancement parameter on filter material, hence on the instrument, with a difference of up to 30 % between the AE31 and the AE33 tapes. The wavelength dependence and day–night variations were small – the difference between the smallest and largest value was up to 6 %. Data from the different instruments were used as input to the so-called “Aethalometer model” for optical source apportionment, and instrument dependence of the results was investigated. Inconsistencies among the source apportionment were found fixing the AE31 and AE33 multiple-scattering enhancement parameters to their usual values. In contrast, optimised multiple-scattering enhancement parameters led to a 5 % agreement among the approaches. Also, the component apportionment “MWAA model” (Multi-Wavelength Absorption Analyzer model) was applied to the dataset. It was less sensitive to the instrument and the number of wavelengths, whereas significant differences in the determination of the absorption Ångström exponent for brown carbon were found (up to 22 %).

Published: April 2021

Cara penularan terbanyak adalah melalui heteroseks (66,95%), hal ini dapat berdampak terjadinya penularan pada perempuan sehingga perempuan menjadi kelompok yang paling rentan tertular HIV dari pasangan atau suaminya. Kerentanan tertularnya perempuan oleh HIV ini diakibatkan oleh adanya ketimpangan gender, faktor biologis, ekonomi dan sosial budaya. Terjadinya penularan pada perempuan yang berdampak juga penularan pada anak yang disebut MTCT (mother to child transmission), transmisi ini dapat terjadi selama kehamilan, persalinan dan menyusui. Kejadian HIV pada anak semakin meningkat seiring dengan peningkatan kejadian HIV pada ibu, berdasarkan laporan Kemenkes triwulan pertama tahun 2011, kejadian AIDS pada anak dengan rentang usia kurang dari satu tahun adalah 2,85 %, anak usia balita sebanyak 1,17 %, anak usia 5 sampai 14 tahun sebanyak 1,42% dan anak usia 15 sampai 19 tahun sebanyak 3,13 % sehingga total kejadian AIDS pada anak sebesar 8,56 % atau peringkat kedua setelah usia dewasa (Kemenkes RI, 2011).
Masalah kesehatan pada anak dengan HIV/AIDS adalah dapat kegagalan tumbuh kembang anak, pada kasus tertentu sangat mungkin anak menjadi yatim piatu lebih dini atau terjadi peningkatan biaya pemeliharaan kesehatan yang lebih besar daripada anak normal. Anak yang terinfeksi HIV harus menghadapi berbagai tantangan dalam hidupnya, seperti menghadapi kehilangan atau kematian orangtua, penyesuaian terus menerus dengan penyakitnya, masalah kesehatan dan psikologis orangtua mereka, dan masalah psikologis mereka sendiri. Anak-anak yang terinfeksi HIV rentan terhadap masalah fisik dan psikososial yang kompleks. Hal ini menimbulkan permasalahan atau stressor pada perempuan dalam merawat anak dengan HIV/AIDS. Perempuan dengan HIV/AIDS memiliki peran ganda dalam merawat anak yang mengalami HIV da diri sendiri yang mengalami HIV/AIDS juga. Penelitian ini dilakukan di LSM HIV/AIDS di kota Bandung dan Cimahi. Diharapkan penelitian ini dapat memberikan masukan untuk peningkatan kemampuan mengenal dan mengatasi stressor pada perempuan dengan HIV?AIDS dalam merawat anak dengan HIV/AIDS.

Published: April 2021

In this study, hexadecanol-myristic acid (HD-MA) binary eutectic mixtures were adsorbed into activated carbon (AC) to prepare the composite phase transition materials(CPCMs). In the hexadecanol-myristic acid/activated carbon (HD-MA/AC) composites, the mixture of HD–MA acted as the phase change energy storage material and the AC was used as the matrix supporting material. Activated carbon is a kind of inorganic supporting material, which has developed pore structure, strong adsorption, high mechanical strength, corrosion resistance and good thermal stability. As the supporting material, activated carbon was helpful to prevent the eutectics from leakage. The chemical structure and crystal phase structure of HD-MA/AC composites were tested by FT-IR and XRD. The microstructure of the composites was observed through field emission scanning electron microscopy (FE-SEM). It was found that the organic binary eutectics were adsorbed on the surface and inside by activated carbon. Thermal properties of the composites were measured by differential scanning calorimetry (DSC). The results of performance test demonstrated that the satisfactory sample CPCM1 melted at 42.38 °C with latent heat of 76.24 J/g and solidified at 38.32 °C with latent heat of 67.08 J/g. The test results of TGA indicated that the prepared composites of hexadecanol-myristic acid/activated carbon possessed great thermal stability and high reliability. It is predicted that the shape-stabilized HD-MA/AC composites have great potential for thermal energy storage.

In this study, the influence of different cyclic treatment and reuse process on the performance of the conversion film was systematically studied by electrochemical test, surface characterization and determination of cobalt ions in the conversion solution, and new technology of chemical conversion of cobalt salts in aluminum alloys were determined. Mode A indicated the practice of cyclical processing of the test object in the original conversion solution, in which components of the circulation liquid were consumed continuously. After the first cycle, the Ecorr and Rp were – 691.8 V and 63.5 kΩ. In the later time, Rp was just about 13.0 kΩ, and the corrosion resistance of conversion film degraded progressively. Mode B represented the practice of adding to the original solution before cyclical processing of the test object, so that volume of the solution remains unchanged, and components of the circulation liquid kept increasing. RP increased from 9.3 kΩ to the 69.9 kΩ at the beginning of the cycle, followed by a slow descent, and content of cobalt in the film was stable, also higher than that under model A. This demonstrates that mode A has high utilization of the cobalt in the conversion solution in the early recycling, whereas mode B can prolong the cyclic service life of the conversion solution in circulation. After adding oxidants, as NaClO3, NaBrO3, H2O2, NaClO, and KMnO4, to the circulation liquid before recycling, the reuse and recycle ratio of cobalt reaches up to 41.3 %, and Rp can be promoted to123.2 kΩ at most. The life of the recycling was prolonged, while the costs of chemical conversion of cobalt were reduced.

ABSTRACT
Introduction: To evaluate whether the presence of bone metastasis in hospitalized patients with prostate cancer (PCa) is associated with a longer length of stay (LOS) when compared to LOS estimated by diagnosis-related groups (DRG). Methods: We performed a retrospective analysis of 86 admissions of patients with PCa at our facility in 2018-2019. Admissions were divided into two groups based on actual LOS and LOS estimated by DRG: group 1 (actual LOS=DRG-LOS) and group 2 (actual LOS<DRG-LOS). The association of bone metastasis and other variables with increased LOS was evaluated by logistic regression with univariable and multivariable analysis, controlling baseline patient characteristics. Results: Longer LOS was not associated with baseline characteristics (age, body mass index, and presence of comorbidities), but was significantly associated with type of admission and ICU (intensive care unit) admission during hospitalization (p<0.05). Bone metastasis was observed in 28 (68.3%) of group 2 admissions and was independently associated with increased LOS (group 2) on univariable and multivariable analysis (OR=4.76, 95% CI=1.91-11.8, p=0.001; OR=3.48, 95% CI=1.08-11.2, p=0.03, respectively). Conclusion: Among clinical or surgical admissions of patients with PCa over a 1-year period, presence of bone metastasis was independently associated with increased LOS when compared to LOS estimated by DRG. The presence of bone metastasis may be used to identify possible outliers not recognized by the DRG system.
Design and Implementation of Bridge Simulator Systems for High Speed Ships
Authors: Miller Eugene , Gladhill Jeff , Fox Brett 
Published: April 2021

This paper provides an introduction to the requirements, design and implementation of bridge simulator systems to support the training of operators and bridge teams for fast ships. Consistent with the practice for conventional ships, there is a trend to use bridge simulator systems to support the training of individual operators and bridge teams of fast ships. This also applies to a lesser degree to support the training of operators of high speed boats. Although they share much in common with bridge simulators for conventional ships, bridge simulator systems for fast ships have to support additional or different emphasis on training requirements. These training requirements arise due to the inherent nature of fast ships (operation at high speeds) and the design features typically implemented in fast ships. In the context of this paper, fast implies the capability to operate for sustained periods at speeds in excess of 30 kts.
The following sections provides some background information, discuss the training requirements that are specific to fast ships, the translation of these training requirements into requirements for fast ship bridge simulator and then some examples related to the implementation of these simulator requirements in existing systems.
