Published: September 2019

Manusia tidak suka akan kebisingan. Kebisingan didefinisikan sebagai suara yang tidak diinginkan. Teknik pengendalian kebisingan memainkan peranan penting untuk menciptakan suasana lingkungan akustik yang nyaman. Ini dapat tercapai ketika intensitas suara diturunkan ke level yang tidak mengganggu pendengaran manusia. Pencapaian lingkungan akustik yang nyaman ini dapat diperoleh dengan menggunakan beragam teknik. Salah satu teknik tersebut adalah dengan menyerap suara. Akan tetapi penggunaan bahan baku penyerap suara dapat dimodifikasi untuk mengurangi penggunaan bahan yang relatif mahal dan terbatas. Salah satu ciri dari aktivitas perancangan adalah bahwa selalu dimulai dari akhir dan berakhir di awal. Artinya fokus dari semua aktivitas perancangan adalah titik akhir (deskripsi produk). Salah satu karakteristik manusia adalah mereka selalu berusaha menciptakan sesuatu baik alat maupun benda lainnya untuk membantu kehidupan mereka. Untuk mewujudkan benda tersebut diperlukan suatu rancangan atau desain. Metode penelitian yang digunakan adalah metode eksperimental yang menguji kemampuan penyerapan bunyi yang dihasilkan dari bahan pelepah pisang dan benang wol dengan berbagai bentuk anyaman yang berbeda dan memilki kemampuan paling optimum dalam meredam bunyi. Penelitian ini nantinya akan menunjukkan bagaimana pengaruh penambahan benang wol dan limbah batang Pisang Kepok terhadap rancangan produk penyerap suara. Sehingga paduan kombinasi wol dan limbah batang Pisang Kepok ini dapat dijadikan sebagai material akustik untuk penanggulangan kebisingan. Hasil penilitian ini menunjukkan peningkatan nilai penyerapan suara dengan kombinasi. Nilai koefisien absorpsi paling baik pada paduan benang wol-limbah batang Pisang Kepok terjadi pada frekuensi menengah dan tinggi.

Authors: Siregar Kamal Basri
Published: September 2019

The responsiveness of neoadjuvant chemotherapy in Triple Negative Breast Cancer (TNBC) needs determination to prevent overtreatment with chemoresistance regimen. A total of 60 consented patients from Haji Adam Malik and Bunda Thamrin Hospital were included in this cohort prospectie study. Patients with heart, kidney, liver disease, history of surgery, chemotherapy, or hormonal therapy were excluded. Apoptotic indexes were taken from all subjects before and after neoadjuvant chemotherapy. After 3 cycles of neoadjuvant chemotherapy, 31 subjects (51.7%) did not show clinical response while 29 subjects (48.3%) had clinical response. There was no significant difference of apoptotic index before and after neoadjuvant chemotherapy (5.47+1.38 vs 5.52+1.08 pg/mL). There was also no significant relationship between apoptosis index and clinical response (p=0.993). This study showed that apoptotic index fails to be neoadjuvant chemotherapy response predictor in triple negative breast cancer. Further research with larger samples is needed to confirm this result

The aim of this study was to analyze the chronic effect various type of exercises to fasting blood glucose (FBG) and insulin resistance in DM type-2 model rats. It was an experimental study, twenty male Wistar rats, age 8 weeks, weight 150-180 gram as the object. Rats were given high fed diet for 4 weeks then injected streptozocin dose 30 mg/kgBB in citrate buffer pH 4.5 i.p, and 45 mg/kgBB  at the following week. Groups were divided into i.e moderate continous training (MCT), severe continous training (SCT), slow interval training (SIT), and fast interval training (FIT). All groups were treated with ran on the treadmill three times a week for 8 weeks. Fasting blood glucose and fasting insulin were checked before and after intervention. Insulin resistance was determined by calculating HOMA-IR. Data analized with paired t-test (p<0,05). The results shown that all group significantly decreased fasting blood glucose and insulin resistance (p <0,05) after eight weeks exercise except insulin resistance in MCT group.  Fasting blood glucose and insulin resistence post-test was found lowest in SIT groups in this study.  In conclucions chronic effect of aerobic continous and aerobic interval in various intensity can decrease fasting blood glucose and insulin resistance in DM type-2 rat model. Slow interval training was the best exercise model to decrease insulin resistance.

Blastocytosis hominis: Unboxing Its Clinical Significance
Authors: Rozi Muhammad Fakhrur , Darlan Dewi Masyithah
Published: September 2019

Abstract. Blastocystis hominisis a unicellular parasite classified as stramenopiles found in human and other mammals. The prevalence varies depending on the region, higher in developing country. The organism is transmitted via fecal-oral route by ingestion of oocyst contaminated food or water. Travelers also have high-risk of having blastocytstis infection. Based on recent studies, several proposed virulence factor are also identified but it remains elusive. The advanced technique has been used to describe its genetic variation and diversity that might be related to its clinical significance. There are 6 distinct morphological forms of Blastocystis including vacuolar, granular, ameboid, and cystic form. The cystic form is considered as an infective form of the organism. Exposure to animals is suggested as the other transmission route, consequently, the infection is also considered as zoonotic infection. It can produce broad clinical manifestation ranging from asymptomatic, self-limiting diarrhea until severe watery diarrhea, depends on host factors and the organism subtype. The organism can produce pruritus and urticaria, proved in literature. Since its pathogenicity remains unclear, conservative management is still suggested to all asymptomatic-symptomatic blastocytosis patients in accordance to patient’s immune status.

Published: September 2019

Background. Based on the Indonesian Renal Registry (IRR) data in 2015, the highest incidence of comorbidities in hemodialysis patients in Indonesia was hypertension (50%). Obstructive Sleep Apnea (OSA) is one of the causes of secondary hypertension, the characteristics of hypertension in OSA are more resistant to treatment. One of the causes of resistant hypertension is patient non-compliance with the consumption of antihypertensive drugs.

Aim. To determine the relationship of adherence of consumption of antihypertensive drugs with obstructive sleep apnea in regular HD patients.

Method. This cross-sectional study involved 89 outpatients in HD units at the Rasyida Kidney Hospital in 2018. Data was obtained through interview using the STOP-BANG questionnaire to assess the of risk of OSA and using Morisky Medication Adherence Scale (MMAS) questionnaire to measure the compliance of  drug consumption.

Results.The prevalence of OSA  in HD patients was (39.3%). There was no significant relationship between adherence with drug consumption and OSA risk, but in bivariate analysis, age (p = 0.0001), body mass index (BMI) (p = 0.001), and gender (p = 0.03) were significantly related to OSA. In multivariate, age and BMI were significantly associated with OSA (OR: 6.449, 95% CI 2.246 ± 18.520, p = 0.001; OR: 6.130, 95% CI 2.105 ± 17.849, p = 0.001).

Conclusion. OSA was not statistically related to adherence to antihypertensive drug consumption in HD patients but was significantly associated with age and BMI.

The article presents data on serological studies of 573 sera samples of cattle that were collected from the farms affected by leptospirosis in different regions of Ukraine in the period of 2014–2015. Samples were investigated by the microscopic agglutination test (MAT), which was conducted within eight serological groups of Leptospira and nine serovars: Sejroe (serovars polonica and hardjo), Hebdomadis (serovar kabura), Tarassovi (serovar tarassovi), Pomona (serovar pomona), Grippotyphosa (serovar grippotyphosa), Canicola (serovar canicola), Icterohaemorrhagiae (serovar copenhageni), and Australis (serovar bratislava). The circulation of L. interrogans serovar hardjo among cattle has been observed in all 11 regions of Ukraine investigated within 25.8–60.0% of the leptospirosis-positive serum samples in these regions. Antibodies in the cattle sera against serovar hardjo (serogroup Sejroe) were detected in 139 of the 370 cows reacting positively in MAT. Overall, they were detected in 24.3% animals out of the total of 573 cows investigated. These are the preliminary results, however, in our opinion, they should allow to include the serovar hardjo in a standard panel of strains for MAT in Ukraine.

The data on susceptibility to antifungals of new species within Candida glabrata complex are limited. Our study was to enrich a global knowledge of yeast epidemiology and drug resistance. The study was focused on the identification of species within clinical isolates of the C. glabrata complex and on the determination of their resistance to antifungals. Four hundred forty-five clinical C. glabrata sensu lato strains were isolated from different clinical samples at routine mycological exams at the Infant Jesus Teaching Hospital in Warsaw. The identification of the most of tested isolates to species complex level was performed using the ID 32 C system. The identification of C. nivariensis and C. bracarensis species within the C. glabrata complex was performed by DNA sequencing. The MICs of amphotericin B, fluconazole, itraconazole, posaconazole, voriconazole, caspofungin, anidulafungin, and micafungin were determined by E-test. Twenty-four isolates did not have an ITS-1 region, characteristic of C. glabrata sensu stricto and their D1/D2 regions of the 26S rRNA were 99% homologous to C. nivariensis 26S rRNA. No strains of C. bracarensis were recovered. C. nivariensis strains were very susceptible to amphotericin B, anidulafungin, micafungin, and caspofungin. Ninety-two percent of C. nivariensis were resistant to itraconazole. The halves of the strains was resistant to posaconazole. Eighty-three percent of C. nivariensis were susceptible to voriconazole. None of the tested strains were susceptible to fluconazole. In the present study, none of the C. nivariensis strains were simultaneously resistant to azoles and echinocandins. C. nivariensis should be recognized as an emerging pathogen, resistant to azoles.

Published: September 2019

Among the species belonging to the Aspergillus section Versicolores, Aspergillus creber has been poorly studied and still unexplored for its biological activities. The present study was undertaken to analyze A. creber extract and to evaluate its in vitro antimicrobial and anti-oxidant activities. UHPLC-MS/MS analysis of A. creber extract allowed the characterization of five known fungal metabolites including: asperlactone, emodin, sterigmatocystin, deoxybrevianamide E, and norsolorinic acid. The highest antimicrobial activity was displayed against Candida albicans, with a mean strongest inhibition zone of 20.6 ± 0.8 mm, followed by Gram-positive drug-resistant bacteria. The MIC values of A. creber extract varied from 0.325 mg/ml to 5 mg/ml. A. creber extract was shown a potent antioxidant activity and a high level of phenolic compounds by recording 89.28% scavenging effect for DPPH free radical, 92.93% in ABTS assay, and 85.76 mg gallic acid equivalents/g extract in Folin-Ciocalteu assay. To our knowledge, this is the first study concerning biological and chemical activities of A. creber species. Based on the obtained results, A. creber could be a promising source of natural antimicrobial and antioxidant compounds.

Published: September 2019

Mutations associated with the pol and the S gene can emerge as a consequence of the high replication capacity and proofreading deficiencies of hepatitis B virus during replication. The current study was constructed to evaluate primary, partial, compensatory and the escape mutations in chronic hepatitis B patients in Northern Cyprus. The samples of HBsAg positive treatment naïve 100 patients were involved in this study. HBV pol gene region was sequenced, amplified and HBV pol/S gene mutations were determined. The samples of thirty-two patients were excluded because of their low viral load (HBV < 1000 ıu/ml). Among the sequenced 68 samples, there was a partial mutation (1.5%) and 36.7% displayed a resistance profile to lamivudine, adevofir, and telbivudine. Immune response escape, vaccine escape, HBIg and diagnosis escape mutations were determined in 24%, 10%, 6%, and 4% samples of the patients, respectively. Additionally, there were six different combined mutations. These data underscored that there is no concern for primary mutations in Northern Cyprus, however, we have identified a compensatory mutation (rtV173M) that may have primary mutation characteristics by combining with other mutation patterns. Additionally, HBsAg escape mutants demonstrated that detection of the S gene together with the pol gene mutations might be beneficial and important to monitor the surveillance of S variants.

This study conducts a comparative phenotypic and genetic analysis of C. perfringens strains isolated from two patients hospitalized at the same time in 2017 in the surgical ward of the Provincial Specialist Hospital in Włocławek (Kujawsko-Pomorskie Province) who developed necrotizing soft tissue infections (NSTI). To explain the recurring cases of this infection, a comparative analysis was performed for these strains and the ones originating from infections recorded at the same hospital in three patients with gas gangrene in 2015. The two C. perfringens isolates studied in 2017 (8554/M/17 from patient No. 1 and 8567/M/17 from patient No. 2) had identical biochemical profiles. A comparison of research results using multiplex PCR from 2017 with a genetic analysis of strains from 2015 enabled us to demonstrate that the strains currently studied have the genes encoding the same toxins (α and β2) as the two strains analyzed in 2015: no. 7143 (patient No. 3) and no. 7149 (patient No. 2). A comparative analysis of the strain profiles obtained with pulsed-field gel electrophoresis (PFGE) in 2017 with the results from 2015 has found one identical and genetically unique restriction profile, corresponding to one clone of C. perfringens comprising of two strains: no. 8567/M/17 (patient No. 2 in 2017) and no. 7143 (patient No. 3 in 2015). The epidemiological data and detailed analysis of the course of both events suggest that this clone of C. perfringens possibly survived in adverse conditions of the external environment in the operating block of this hospital for many months.

Streptococcus iniae is a pathogenic and zoonotic bacteria that impacted high mortality to many fish species as well as capable of causing serious disease to humans. Alanine racemase (Alr, EC 5.1.1.1) is a pyridoxal-5’-phosphate (PLP)-containing homodimeric enzyme that catalyzes the racemization of L-alanine and D-alanine. In this study, we purified alanine racemase from S. iniae that was isolated from an infected Chinese sturgeon (Acipenser sinensis), as well as determined its biochemical characteristics and inhibitors. The alr gene has an open reading frame (ORF) of 1107 bp, encoding a protein of 369 amino acids, which has a molecular mass of 40 kDa. The enzyme has optimal activity at a temperature of 35°C and a pH of 9.5. It belongs to the PLP-dependent enzymes family and is highly specific to L-alanine. S. iniae Alr (SiAlr) could be inhibited by some metal ions, hydroxylamine and dithiothreitol (DTT). The kinetic parameters K

m
and V

max
of the enzyme were 33.11 mM, 2426 units/mg for L-alanine, and 14.36 mM, 963.6 units/mg for D-alanine. Finally, the 50% inhibitory concentrations (IC50) values and antibiotic activity of two alanine racemase inhibitors (homogentisic acid and hydroquinone), were determined and found to be effective against both Gram-positive and Gram-negative bacteria employed in this study.

Published: September 2019

The aim of the study was to analyze the reasons for removing implants after breast reconstruction in the course of treatment of breast cancer. The study involved 428 patients, who underwent a total of 648 breast reconstruction procedures using artificial implants. 47 out of 648 cases (7.3%) were identified in which the implant had to be removed. Of the 47 cases, 57.4% had undergone deferred reconstruction, and 42.6% immediate reconstruction; 27.7% had undergone pre-operative chemotherapy and radiotherapy, 27.7% pre-operative chemotherapy, and 2.1% pre-operative radiotherapy; 6.4% were diabetic, 4.3% active smokers, and more than 50.0% had BMI greater than 25 kg/m2. In 83.0% of the analyzed cases, the reason for removal of the implant was infection, in 8.5% it was local recurrence of breast cancer, in 4.3% it was damage (leakage) of the implant, and in 2.1% it was post-operative pain. About 87.0% of infections appeared within one year of implantation; however, less than a half developed within 90 days of the reconstructive surgery, and up to 30 days only about 13.0% had appeared. Among the etiological agents of infections were: coagulase-negative Staphylococcus (31.3%), Staphylococcus aureus (18.7%), Enterococcus faecalis (9.4%), Enterobacter cloacae (18.8%), Pseudomonas aeruginosa (12.5%), Acinetobacter lwoffii (3.1%), and other Gram-negative fermenting rods accounted for 6.2%. Infections were the most common reason for removing the implant after breast reconstruction. and occurred most often as late infections (>30 days after surgery). The time of observation for infectious complications should be at least 1 year.

Published: September 2019

Elderly people living in nursing homes are a high-risk population for Staphylococcus aureus infection. Multiple comorbidities, a weakened immune system, inadequate hygienic conditions, and crowding might increase the prevalence rates of this opportunistic pathogen. However, the epidemiological aspects, genetic diversity, and transmission of S. aureus in nursing homes are still poorly understood, especially in Poland. This study aimed to determine the genetic relatedness and prevalence of colonization of S. aureus isolated from the anterior nares and the throat of residents and staff in a nursing home located in Lublin, Poland. The study showed a high S. aureus prevalence rate among participants (46.1%), yet there was a low frequency of MRSA strains among residents (1.7%) and staff (0%). The multiple-locus variable-number tandem-repeat fingerprinting (MLVF) analysis demonstrated a high degree of genetic diversity of S. aureus strains colonizing the anterior nares and the throat of the participants. The occurrence of simultaneous colonization with more than one unique S. aureus strain in any one individual as well as the incidence of colonization with the same genetic variant of S. aureus in different individuals was observed. These findings suggest that inter-participant S. aureus transmission might contribute to the development of cross-infections.

The aim of this study was to assess the periodontal status of cystic fibrosis (CF) adult patients and to evaluate whether there is a correlation between the bacterial population of the subgingival biofilm and the health status of the periodontal tissues in this group of adults. The study involved 22 cystic fibrosis adult patients. The periodontal condition was assessed using Plaque Index (PLI), Gingival Index (GI), and Probing Pocket Depth (PPD). The gingival sulcus samples were analyzed by the Real-Time PCR assay (RT-PCR). Majority of patients showed moderate or severe bacterial dental plaque accumulation, but none of them had clinical symptoms of periodontal diseases. RT-PCR showed the presence of periopathogens in 50% of patients. Red complex microorganisms were detected in 9.09%, orange complex in 27.27%, and green complex in 31.82% of the samples analyzed. In cystic fibrosis patients colonized by periopathogens, the periodontal markers were significantly higher in comparison to not colonized by periopathogens patients. Despite the widespread presence of bacterial dental deposits in the cystic fibrosis adult patients examined, none of them has clinical symptoms of periodontal disease; however, the presence of periodontal pathogens in subgingival biofilm may represent a possible risk factor of this disease in the future. An unsatisfactory level of oral hygiene in any patient with cystic fibrosis indicates a need to focus on standards of dental care for such patients.

Antimicrobial peptides (AMPs) are cationic small peptide chains that have good antimicrobial activity against a variety of bacteria, fungi, and viruses. AMP-17 is a recombinant insect AMP obtained by a prokaryotic expression system. However, the full antifungal activity, physicochemical characteristics, and cytotoxicity of AMP-17 were previously unknown. AMP-17 was shown to have good antifungal activity against five pathogenic fungi, with minimum inhibitory concentrations (MIC) of 9.375–18.75 μg/ml, and minimum fungicidal concentrations (MFC) of 18.75–37.5 μg/ml. Notably, the antifungal activity of AMP-17 against Cryptococcus neoformans was superior to that of other Candida spp. In addition, the hemolytic rate of AMP-17 was only 1.47%, even at the high concentration of 16× MIC. AMP-17 was insensitive to temperature and high salt ion concentration, with temperatures of 98°C and –80°C, and NaCl and MgCl2 concentrations of 50–200 mmol/l, having no significant effect on antifungal activity. However, AMP-17 was sensitive to proteases, trypsin, pepsin, and proteinase K. The elucidation of antifungal activity, physicochemical properties and cytotoxicity of AMP-17 provided an experimental basis for its safety evaluation and application, as well as indicated that AMP-17 might be a promising drug.

Published: September 2019

AMIK Ibrahimy Sukorejo Situbondo secara berkala mengadakan evaluasi kinerja dosen setiap akhir perkuliahan seperti pada waktu Ujian Akhir Semester. Kegiatan ini dilakukan  untuk menilai kinerja dosen pada perkuliahan, dengan beberapa kriteria nilai yang telah ditentukan dari pihak AMIK Ibrahimy. Sistem evaluasi ini dilakukan dengan memberikan kuesioner kepada mahasiswa yang kemudian direkap sebagai laporan yang ditujukan kepada direktur. Dan hasil rekapan evaluasi kinerja dosen didistribusikan kepada masing-masing dosen, sehingga dapat mengetahui hasil evaluasi kinerja. Akan tetapi, dengan menggunakan prosedur tersebut membutuhkan waktu lama dalam proses penyebaran angket kuesioner kepada mahasiswa, hal ini terjadi karena tidak adanya petugas khusus dalam menangani kegiatan evaluasi kinerja dosen tersebut. Untuk membantu meminimalisir permasalahan tersebut, perlu dirancang Sistem Informasi Manajemen Evaluasi Kinerja Akademi dan Dosen AMIK Ibrahimy. Dengan adanya sistem ini diharapkan dapat membantu mempercepat pemrosesan penilaian yang selama ini cukup menyita waktu. Sistem ini dibuat menggunakan metode waterfall dengan beberapa tahapan yang dilakukan mulai dari Requirement sampai Maintenance. Dari hasil penelitian ini diharapkan dapat mengatasi masalah-masalah evaluasi kinerja yang selama ini terjadi. Hasil pengujian menjadi tolak ukur apakah sistem ini berjalan dengan baik atau tidak. Tingkat kesesuaian perancangan sistem manajemen evaluasi kinerja ini dapat membantu evaluasi terhadap pelayanan akademi dan kinerja dari dosen.

Published: September 2019

The development of information in a hospital is very fast-growing, where the hospital wants to provide services in the form of information about the hospital using Virtual Reality technology. Likewise with Jemursari Islamic Hospital, which is developing the VR-Patient Room application. For the development of VR-Patient Rooms, several assets are needed in the form of devices or equipment located in the hospital. In this study, assets were developed using the photo-realism method. Assets are built by following the criteria of photo-realism, following the scale of size and using 3D applications. Assets built include patient beds, furniture (tables, guest sofas, wall clocks), trash bins, and patient desks to the toilet and shower. After all assets are built, an experiment is conducted using survey methods to measure the realistic level of assets. From these experiments obtained a realistic level of the assets made have an average value above 3.7 from a scale of 5, which means that the 3D assets made are approaching objects with photo-realism characteristics.
