The aim of this retrospective study was to investigatethe prevalence of A.baumannii from routine clinical specimens sent to clinical microbiologylaboratory RSUP HAM Medan and its susceptibility pattern to various antibiotics. Identificationand susceptibility testing of A. baumannii was performed by Vitek 2 with Advanced ExpertSystem (AES). A total of 644/3693 (17.44%) A.baumannii isolates were identified from variousclinical specimens. From those isolates, there were 147 (23%) isolates of carbapenemresistentA.baumannii (imipenem and meropenem). A.baumannii mainly isolated from sputumspecimens, and most isolates were highly sensitive to colistin, amikacin and tigecycline.Low prevalence of A.baumannii was found in this study. However, the isolates showed highresistence level to antibiotics, particularly penicillin, cephalosporin and fluoroquinolones.

Abstract

COVID-19 hits Indonesia with massive social restrictions in many aspects of life. In some Indonesian rural areas, information related to the pandemic through online platforms and social media is accessible. However, most of the information is inaccurate. Improving individual knowledge is crucial to support the government’s campaign for COVID-19 prevention. This cross-sectional, pretest-posttest study aims to evaluate the knowledge and attitude of health personnel toward COVID-19 prevention in a primary healthcare facility in a rural area of North Sumatra. All twenty-two health personnel who worked in the hospital during the study were asked to fill in a two-sectioned questionnaire. The first section contained questions related to knowledge, and the second section was related to attitude toward COVID-19. Following the educational activity, each health personnel filled in the same questionnaire again. We analyzed the data statistically using two-way ANOVA (p<0.05, 95% CI). There were increases in knowledge (p < 0.001) and attitude (p = 0.0002) of the health personnel after the educational activity. Educational activity improves health personnel’s knowledge and attitude regarding COVID-19 prevention.

Abstract

Leptospirosis is an infectious disease caused by spirochete from the genus Leptospira, namely Leptospira interrogans which is pathogenic for both humans and animals. L. interrogans infection is often associated with flooding, where L. interrogans is carried from soil contaminated with animal urine reservoirs and settles in water. Leptospirosis is estimated to cause 1030000 cases and 58900 deaths annually worldwide. Until now, Leptospirosis is still a threat to public health because it causes Extraordinary Events (KLB) in several regions in Indonesia. Leptospirosis outbreaks are related to the presence of risk factors, namely the high population of rats as reservoirs of Leptospira spp., poor environmental sanitation, and the increasing number of flood areas in Indonesia. The purpose of this study was to determine the relationship between knowledge and attitude with the behavior of preventing Leptospirosis in healthcare workers at the Sub-District Health Center, Binjai Timur, Binjai City, against Leptospirosis. This research is an analytic study with a cross sectional design. The research was conducted using a questionnaire instrument of knowledge level about Leptospirosis, attitudes towards Leptospirosis, and preventive behavior towards Leptospirosis.

Abstract

Systemic lupus erythematosus (SLE) is a prevalent autoimmune disease affecting multiple organ systems. Disease progression is inevitable as part of its natural course, necessitating aggressive therapeutic strategies, particularly with the use of immunosuppressants. Long-term use of steroids and other immunosuppressants is associated with significant adverse effects. Mesenchymal stem cells (MSCs) have been shown to modulate the immune response, leading to immunosuppressive effects against self-antigens. MSCs have demonstrated the ability to modulate several immune cell populations, contributing to favorable outcomes in controlling immune and inflammatory conditions. Recent evidence has shown an increase in Treg and Breg cell subsets following MSC administration, along with modulation of other immune cells, including dendritic cells, B cells, and T cells. However, the balance between MSC pro-inflammatory and anti-inflammatory phenotypic activation remains a critical factor in determining therapeutic outcomes. Various covariates also influence the efficacy of MSC therapy. The aim of this study was to provide a comprehensive overview of the utilization of mesenchymal stem cells (MSCs) in SLE treatment, leveraging their immunomodulatory and immunosuppressive capabilities. Understanding the fundamental preclinical effects of MSCs and recent findings from clinical studies may enhance the potential of MSC therapy in the management of SLE patients.

Abstract

Background: Durio zibethinus (durian) contains secondary metabolites with antibacterial potency, such as alkaloids, flavonoids, saponins, tannins, and glycosides. Indonesia is one of the world’s largest producing countries of durian, yet the thorny part of the fruit rind often ends up as waste. Investigations of durian rind for its antimicrobial activity will maximize the benefits and prevent waste accumulation. Objective: In this experimental study, we analyzed the antimicrobial activity of ethanolic extract of durian rind against extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli and K. pneumoniae in vitro. Methods: This study used a one-group posttest-only design. The disc diffusion method for antimicrobial susceptibility test was used to test the ethanolic extract of durian rind against ESBL-producing E. coli and K. pneumoniae, each with six experimental repetitions to observe the inhibition zone produced around discs containing the extracts at various concentrations (12.5%, 25%, 50%, 75%, 80%, and 100%). Results: Ethanolic extract of durian rind showed an inhibition zone against ESBL-producing E. coli at the extract concentration of 50%, with an average inhibition zone of 3.57 mm. The inhibition zone was also observed against ESBL-producing K. pneumoniae at the extract concentration of 75%, with an average inhibition zone of 3.73 mm. Conclusions: The ethanolic extract of durian rind showed inhibition zones against ESBL-producing E. coli and K. pneumoniae, showing its potential antimicrobial activity in vitro.

Abstract

This study compares the direct PCR method with standard PCR to detect Escherichia coli. Escherichia coli is the most widely used organism in biology. Detection of E. coli in water and food is routinely performed, utilizing methods like PCR. The initial stage of PCR preparation involves DNA extraction, which requires a commercial kit. Consequently, this extraction process incurs additional expenses, time, and labor. Therefore, an alternative method is needed, such as direct PCR, which can circumvent the need for DNA extraction. The PCR process facilitates lysis of the bacterial cell wall, releasing nucleic acids, which can then be amplified by Taq polymerase. For the PCR procedure, two groups were formed, each comprising three replicates of the reaction with different DNA templates. The first group utilized a direct culture of Escherichia coli, while the second group incorporated the extracted DNA of Escherichia coli. Our study successfully amplified the metH gene of Escherichia coli without DNA extraction. Electrophoresis analysis revealed that the direct PCR product, sized at 300 bp, appeared more pronounced than the standard PCR product. The findings of this research demonstrated direct PCR as an alternative for detecting Escherichia coli, which would lead to reductions in costs, time, and labor.

Abstract

Maternal Mortality (MMR) is still a global health problem that needs serious attention. In 2022, Deli Serdang Regency was recorded to have the highest AKI in North Sumatra Province, which was 16 per 42,363 live births. One of the efforts that can be made to reduce this number is by using the Maternal and Child Health Book (KIA). This study aims to analyze the relationship between the level of knowledge of pregnant women and the use of KIA books at the Tanjung Rejo Health Center, Deli Serdang Regency. This study uses an analytical observational design with a cross-sectional approach. A total of 100 pregnant women became respondents to the study. Data was collected through questionnaires, then analyzed using the Spearman statistical test. The use of KIA books is assessed through indicators of readability, comprehension, and application of information, while mother's knowledge is measured through the level of mastery of the content of KIA books. The results showed that the majority of pregnant women were at healthy reproductive age (55%), poorly educated (72%), unemployed (89%), and had high parity (56%). Most respondents (73%) fall into the category of poor utilization of KIA books, while 79% have a low level of knowledge. Statistical analysis showed a significant relationship between the level of knowledge of pregnant women and the use of KIA books (p = 0.001). The use of KIA books in pregnant women is significantly influenced by the level of knowledge.

Abstract

Urinary tract infections (UTIs) continue to increase in the number of cases and death rates every year. This increase in the number of deaths is due to an increasing trend in UTI cases in elderly patients. In Indonesia, UTI is generally caused by the uropathogenic Escherichia coli (UPEC) strain. The existence of resistant bacterial infections also triggers increased mortality in UTI patients. Several types of herbs, such as cranberries, are often used traditionally to treat UTI symptoms. Another herb that is also known to have antibacterial effects is lime. This experimental study examined the in vitro antimicrobial effects of ethanol extract of cranberry (Vaccinium macrocarpon) and ethanol extract of lime (Citrus aurantifolia L.) against UPEC by the Kirby-Bauer disc diffusion method. This study used a clinical sample obtained from an outpatient diagnosed with UTI in the Prof. dr. Chairuddin P. Lubis Universitas Sumatera Utara Hospital in March 2023. The UPEC strain was isolated and identified using the Vitek 2 Compact automated system at a local university hospital. The antimicrobial susceptibility test results indicated that the ethanol extract of cranberry did not produce an inhibition zone at concentrations of 12.5%, 25%, 50%, 60%, 70%, and 96%. The ethanol extract of lime demonstrated inhibitory zones against UPEC, with a mean diameter of 12.01 mm at a concentration of 12.5% and a mean diameter of 15.62 mm at 96%. The cranberry extract did not demonstrate an inhibitory zone against UPEC in vitro, whereas the lime extract did.

Abstract

Introduction: Physical activity contributes to mental well-being by stimulating neurotransmitters associated with pleasure and positive mood. Understanding this relationship within specific populations is important for promoting community health. Objective: This study aimed to evaluate the correlation between physical activity and happiness among residents of Medan, Indonesia. Methods: This cross-sectional study was conducted in Medan from May to November 2021 and involved 260 participants. Physical activity was assessed using the International Physical Activity Questionnaire, while happiness and affect were measured using the Oxford Happiness Questionnaire and the Positive and Negative Affect Scale. Data were analyzed using Spearman’s rank correlation test. Results: Overall physical activity was positively correlated with happiness (r = 0.132; p = 0.034) and positive affect (r = 0.214; p = 0.001). Vigorous physical activity showed positive correlations with happiness (r = 0.185; p = 0.003) and positive affect (r = 0.244; p = 0.001). Walking was also positively correlated with happiness (r = 0.132; p = 0.034) and positive affect (r = 0.214; p = 0.001). Moderate physical activity was not correlated with happiness (r = –0.017; p > 0.05) or positive affect (r = 0.065; p > 0.05). No correlation was found between physical activity and negative affect. Conclusions: Physical activity is positively correlated with happiness among residents of Medan.
