Excellent performance of hybrid model manufactured via additive manufacturing process reinforced with GFRP for sport climbing equipment.

The figure eight model was successfully manufactured, analyzed, and characterized in the present study. The model was manufactured via 3D printing fused deposition modelling (FDM) and then reinforced with glass fiber-reinforced polymers (GFRP). There are three different designs in figure eight that are examined, and each design is made using 3D printing FDM and coated with GFRP, a hybrid material, as shown. Specimens that have been made from each design are then evaluated by tensile test, hardness test, surface roughness test, and density test. The results showed that the hybrid figure eight lamination with polylactic acid (PLA) and GFRP material could increase the tensile strength by more than two times higher. The highest tensile strength lies in design 1 with 4977, 3 N. Moreover, the highest hardness value occurred for design two at 75.1 Shore D, and the highest average density lies in design three at 1.2 g/mm3. The study also showed that the lowest cost occurred in hybrid design three at $ 1.2 per item. Based on the present study, the GFRP reinforcement can extend the model's performance with affordable cost and retain figure eight from the failure.

Side Effects after mRNA COVID-19 Vaccine as a Booster in Health Workers.

Background: In Indonesia, around 400 health workers died due to Covid-19 between June-July 2021, therefore the health workers need to be given further immunity. Health workers were among the first to get a booster shoot. However, they may experience side effects after vaccination. We aimed to describe side effects of Moderna vaccine as a booster in health workers. Methods: A cross sectional study was conducted on health workers who received mRNA Covid-19 vaccine booster (Moderna) at Sulianti Saroso Infectious Disease Hospital, Indonesia and had filled the questionnaire assessing side effects form. We associated the form of the questionnaire assessing side effects from the originating source of hospital immunization unit in September 2021. Results: A total of 101 health workers who received mRNA Covid-19 vaccine booster in Jul-Aug 2021 were included. Most of health worker experienced more than 3 side effects. The side effects were sore arm (100%); chills (72%); fatigue (57%); headache (53%) and fever (51%), other symptoms (28%). The side effects mostly happened a day of receiving a booster shot (61.4%). There was no association between age, gender, comorbid to amount of side effects (P>0.05). Conclusion: Since the public must fulfil the immunization program during pandemic, it is the responsibility of the healthcare provider to inform about the potential side effects and benefits of a new Covid-19 vaccine.

Antimicrobial Sensitivity Pattern from Hospitalized Pneumonia Patients in National Referral Infectious Disease Hospital in Indonesia.

Background: Pneumonia is still a major global problem with high morbidity and mortality. The increasing number of pneumonia cases caused by bacteria, especially multidrug-resistant pathogens, increasing age of the population, patients with chronic disease (comorbid), and inappropriate antimicrobial therapy at initial administration make the treatment become less effective. These issues finally contribute to higher morbidity and mortality in cases of hospitalized pneumonia patients. Therefore, it is crucial to know the microbial pattern and select the therapy according to local antimicrobial sensitivity patterns. Method: A cross-sectional study was conducted for hospitalized pneumonia patients between January 2015 and December 2016 in Indonesia National Referral Infectious Disease Hospital. Data were collected from medical records to show patient characteristics, antimicrobial treatment data, culture examination, and bacterial sensitivity. Results: A total of 99 pneumonia patients required hospitalization and underwent sputum culture examination. The patients were mostly above 65 years old (32.3%) and male (57.6%). The most common comorbidities were pulmonary tuberculosis (21%), and the others were heart failure, chronic obstructive pulmonary disease (COPD), and HIV/AIDS. Based on the sputum culture, fungi were identified in most specimens (56%), while the bacteria identified were Klebsiella pneumoniae (14%), Acinetobacter sp. (12%), and Pseudomonas sp. (8%). Third-generation cephalosporin, such as ceftriaxone (50%), was commonly used as an antibiotic for pneumonia treatment. Conclusion: Most common bacteria isolated from sputum culture were Klebsiella pneumoniae which were more sensitive to the beta-lactam and aminoglycoside groups. The higher risk factors were age above 65 years old, being male, and having tuberculosis.
