Quality of Life in Patients with Renal Failure Undergoing Hemodialysis.

A good quality of life is one of the many indicators that determine the success of hemodialysis (HD) therapy. Factors that significantly affect the quality of life of patients with renal failure who undergo HD include sociodemographic condition, mental state (depression), severity of kidney disease, accompanying disorders, HD duration, non-adherence towards prescribed medication and nutritional problems. Among said factors, the metabolic and nutritional disorder commonly known as protein energy wasting (PEW), plays an important role in the clinical course of renal failure patients. The aim of nutrition management in patients with renal failure is to slow down the progression of kidney disease, improve quality of life, and reduce cardiovascular morbidity and mortality.

The Association Between Parents History of Type 2 Diabetes with Metabolic Syndrome Component and Insulin Resistance in Non-Diabetic Young Adult Male.

BACKGROUND: the familial nature of type 2 diabetes is manifested by the presence of insulin resistance in non-diabetic first degree relatives. Most of these studies have been performed in middle-aged and there is only few published studies in young age individuals and adolescents. This study aimed to determine the relationship between parents history of type-2 diabetes with metabolic syndrome component and insulin resistance in adolescent non-diabetic subjects. METHODS: this was a cross sectional study comparing the metabolic profile, risk of metabolic syndrome and insulin resistance in non-diabetic male adolescents (17-24 years old) whose one or both parents were with type-2 diabetes. We performed anamnesis, physical examination, fasting plasma glucose, lipid profile, fasting insulin level and insulin resistance based on HOMA-IR. RESULTS: metabolic abnormalities were more prevalent in subjects whose parents were with history of type-2 diabetes, especially their waist circumference, fasting plasma glucose, triglyceride, fasting insulin and HOMA-IR (p=0.000). There was increased risk of developing central obesity in adolescents with parental history of 19.3 fold (95%CI 2.46-151.07) and insulin resistance of 10.3 fold (95%CI 3.89-27.23). Parental history of type-2 diabetes together with metabolic syndrome component ie. waist circumference >90 cm and triglyceride ≥150 mg/dl were strong determinat factors for insulin resistance (R2=50.7%). CONCLUSION: the early multiple metabolic defect can be detected in non-diabetes adolescents with parental history of type-2 diabetes. Cluster of metabolic syndrome component in these subject become  a powerful determinat factor for insulin resistance.

Intra-uterine Growth Retardation and Development of Hypertension.

Low birth weight (LBW) is defined as a birth weight of a liveborn infant of <2,500 gram. In developed countries, LBW is commonly caused by preterm birth; while in developing countries, it is mostly due to intrauterine growth retardation. The concept of developmental origins of adult diseases, particularly on late-onset diseases such as hypertension and kidney disease, implies that there is a correlation between intrauterine milieu, intrauterine growth retardation, premature birth and infant feeding. The 'fetal origin hypothesis' suggests that metabolic diseases are directly related to poor nutritional status in early life.There is an inverse association between LBW and later risk of hypertension. The pathomechanism that links LBW and hypertension is multifactorial including delayed nephrogenesis, genetic factors, sympathetic hyperactivity, endothel dysfunction, elastin deficiencies, insulin resistance and activation of renin-angiotension system.

Cytotoxicity and Apoptosis Studies of Brucein D against T24 Bladder Cancer Cells.

OBJECTIVE: Brucein D (BrD), a quassinoid isolated from Brucea javanica fruit, reportedly demonstrates anti-cancer activity. This study's objective is to evaluate the cytotoxicity of Brucein D and its ability to induce apoptosis in T24 bladder cancer cells. METHODS: We investigated the cytotoxic activity of BrD against the T24 cell through the induction of apoptosis in vitro. This cytotoxic activity was evaluated with ΜΤΤ assay and followed by Calcein-AM/PI viability staining. Apoptotic activity was determined with Hoechst 33342 nuclear staining and DNA fragmentation. Doxorubicin and docetaxel were used as a positive control. Evaluation of apoptotic-related gene expression, Bax, Bak, Bcl2, and p53 was also performed using semi-quantitative PCR analysis. Statistical analysis was conducted using One-way ANOVA followed by post hoc test Turkey's HSD (Honestly Significance Difference). RESULTS: Results show that BrD had high toxicity against T24 bladder cancer cells with an IC50 value of 7.65 ± 1.2 µg/mL but relatively less toxic to 1BR3 normal skin fibroblast cells compared to the doxorubicin and docetaxel treated cells. The viability assay shows that BrD significantly increases the percentage of dead cells relative to control in a dose-dependent manner. Furthermore, the percentage of cells with apoptotic appearance was significantly higher in group treated with BrD IC50 (56.04±3.09%) compared to control (9.42±2.88). The result was similar to doxorubicin IC50 (58.97±12.31) but lower than docetaxel IC50 (74.42±9.79). DNA fragmentation in gel electrophoresis was also observed in T24 cells treated with BrD. Apoptosis was also verified by an alteration in the expression of apoptosis-related genes, upregulation of Bax, Bak, and p53, and downregulation of Bcl-2. CONCLUSION: BrD has shown a cytotoxic effect against T24 bladder cancer cells. Hence, it is a promising natural compound for the management of bladder cancer by induction of apoptosis through activation of the intrinsic pathway, with low toxicity to normal cells.

Evaluation of Blended Learning in Terms of the Perceptions of Medical Students: A Mixed Method Study.

Introduction: The ongoing 4.0 industrial evolution, characterized by the rise of digital technology, has had a massive impact on human lifestyles worldwide. Faculty members in medical school are expected to respond to this industrial revolution by implementing teaching strategies, one of which is Blended learning as a suitable solution to overcome the limitations of space and time in the teaching process. For effective utilization of blended learning, it is important to conduct extensive studies on its implementation. The aim of this study was to assess the effectiveness and efficiency of implementing blended learning in the faculty of medicine in Hasanuddin University from the students' perspective. Methods: This study used a sequential explanatory mixed method approach, combining quantitative and qualitative methods. The quantitative part involved 782 undergraduate medical students from the first, second, and third years. Data were collected through a questionnaire survey distributed among the students. The qualitative part of the research was conducted through focus group discussions involving 13 students based on the questionnaire scores, representing both high and low scores. The results of the quantitative and qualitative research were collected and integrated. Results: Based on the results, the majority of students agreed that blended learning provided many advantages to their learning (Mean±SD: 3.79±0.78). Also, they reported e-learning platform significantly contributed to their learning process (Mean±SD: 3.88±0.67). The workload of blended learning method was still considered quite heavy by students, and good time management was highly needed (Mean±SD: 3.45±0.84). As for qualitative part, some positive results were obtained; they reported that it increased motivation for learning, enhanced the efficiency of learning and gaining adaptability, while the negative opinions were the network error in e-learning, erratic e-learning display, and video quality problem. Conclusion: Most of the students expressed positive opinions about the advantages of blended learning; according to them, learning was more efficient and effective, it enhanced learning motivation, and it provided comprehensive accessible learning materials.

The Effects of High Fat Diet on the Incidence of Obesity and Monocyte Chemoattractant Protein-1 Levels on Histological Changes in Prostate Wistar Rats.

Introduction: Benign prostatic hyperplasia (BPH) is a histopathological diagnosis characterized by the increase in stromal cells and epithelial cells of the prostate gland in the transitional zone surrounding the urethra. Obesity is the risk factor of BPH. The most frequent cause of obesity is a high-fat diet (HFD). Obesity and HFD lead to pro-inflammatory conditions. One of the pathomechanisms for the occurrence of BPH is a low-degree inflammatory factor, one of which is the level of monocyte chemoattractant protein-1/MCP-1. This study aims to determine the influence of HFD on the incidence of obesity and inflammatory factors (monocyte chemoattractant protein-1/MCP-1 levels) on the histopathological picture of the prostate. Methods: Experimental research was performed on male Wistar rats with each of the 6 rats given normal fat (ND) and HFD intake and terminated at 8 weeks and 6 rats given each ND and HFD were terminated at 16 weeks. The determination of obesity was determined based on Lee's criteria which were categorized as obese if the Lee index >0.3 and non-obese if ≤0.3. Examination of circulating MCP-1 was carried out by the ELISA method and determination of prostatic hyperplasia was done by calculating the percentage of prostate glands that had a large per-field cystic dilatation on light microscopy examination. All data are analyzed statistically with the Fisher Exact Test and Spearman Correlation Test. Results: Of the 12 rats that were given ND, none of them became obese according to Lee's criteria, on the other hand, of the 12 rats that were given HFD 8 became obese (66.7%, p = 0.001). Serum MCP-1 levels and the percentage of prostate glands that had cystic dilatation were significantly higher in mice receiving HFD than ND; both at week-8 (MCP-1; 18.87 vs 15.66) and (prostate gland experiencing cystic dilatation; 63.46% vs 47.24%) and week-16 (MCP-1; 21.27 vs 21.27) and (prostate gland experiencing cystic dilatation; 67.79% vs 56.39%). Spearman correlation analysis showed that only circulating MCP-1 levels were significantly correlated (p < 0.05) to the percentage of the prostate gland that had cystic dilatation; especially in week 16 (r = 0.713 and p < 0.001). At 8 weeks, it was not statistically significant (r = 0.406 and p = 0.095). Conclusion: High fat intake has been shown to increase the risk of obesity, but obesity does not increase inflammatory status and the incidence of prostate glands with cystic dilatation. On the other hand, high-fat intake increases inflammatory status which in turn causes prostate glands to develop cystic dilatation.

Association between angiotensin-converting enzyme (ACE) gene I/D polymorphism with the risk of knee OA: A systematic review, meta-analysis, and meta-regression.

Background: Previous studies have linked genetics to knee osteoarthritis. Angiotensin-converting enzyme (ACE) gene I/D polymorphism may cause OA. However, evidence remains inconsistent. This study examines knee OA risk and ACE gene I/D polymorphism. Methods: We explored Europe PMC, Medline, Scopus, and Cochrane Library using keywords. Three assessment bias factors were assessed using the Newcastle-Ottawa Scale (NOS). Criteria for inclusion: (1) Split the study population into knee OA patients and healthy controls; (2) Analysed the ACE gene I/D polymorphism; (3) Case-control or cross-sectional surveys. Studies with non-knee OA, incomplete data, and no full-text were excluded. The odds ratio (OR) and 95% confidence intervals (95% CI) were calculated using random-effect models. Results: A total of 6 case-control studies consist of 1,226 patients with knee OA and 1,145 healthy subjects as controls were included. Our pooled analysis revealed that a significant association between ACE gene I/D polymorphism and risk of knee OA was only seen in the dominant (DD + ID vs. II) [OR 1.69 (95% CI 1.14 - 2.50), p = 0.009, I2 = 72%], and ID vs. II [OR 1.37 (95% CI 1.01- 1.86), p = 0.04, I2 = 43%] genotype models. Other genotype models, including recessive (DD vs. ID + II), alleles (D vs. I), DD vs. ID, and DD vs. II models did not show a significant association with knee OA risk. Further regression analysis revealed that ethnicity and sex may influence those relationships in several genotype models. Conclusions: Dominant and ID vs. II ACE gene I/D polymorphism models increased knee OA risk significantly. More research with larger samples and different ethnic groups is needed to confirm our findings. After ethnicity subgroup analysis, some genetic models in our study showed significant heterogeneities, and most studies are from Asian countries with Asian populations, with little evidence on Arabs.

Virgin Coconut Oil: A Dietary Intervention for Dyslipidaemia in Patients with Diabetes Mellitus.

Hyperlipidaemia is causally related to coronary artery diseases (CAD) and peripheral artery diseases (PAD) in people with Diabetes Mellitus (DM). An in vivo study confirmed that virgin coconut oil (VCO) could maintain levels of lipids in the blood as effectively as conventional therapy. Therefore, this study aimed to determine the effect of VCO on the lipid profiles and ankle-brachial index (ABI) of patients with DM. In this experimental study with pre- and post-test design and a control group, the participants were selected purposively. The ABI was evaluated on the first visit. Baseline lipid profile readings were taken. Each participant took 1.2 mL/kgBW of VCO daily and divided it into three doses. After 30 days of taking VCO, laboratory examinations and ABI were repeated, and adverse events were evaluated. The dependent t-test and Wilcoxon sign rank test with a significance level of α ≤ 0.05 showed a significant decrease in low-density lipoprotein (LDL) (p = 0.002), a significant increase in high-density lipoprotein (HDL) levels (p = 0.031), a significant decrease in energy intake (p = 0.046) and cholesterol intake (p = 0.023) at the endpoint in the VCO group. In conclusion, this therapy is beneficial for maintaining lipid profile when combined with dietary therapy. Future studies should investigate the duration and dosage of VCO on patients to maintain lipid-linked protein.

Factors Influencing the Implementation of Interprofessional Collaborative Practice in Teaching Hospital Setting: A Mixed-Method Study.

Introduction: Health service in the current global era requires health workers to provide qualified service, this also applies to teaching hospitals. Collaboration between several professions involved (doctors, nurses, and pharmacists) in an interprofessional collaboration system is needed in providing such service. Factors influencing interprofessional collaboration is unique to each health care center. The purpose of this study was to determine the factors that influence the implementation of interprofessional collaborative practice among health workers in Dr. Wahidin Sudirohusodo General Hospital. Methods: This is a mixed-method explanatory sequential design study, utilizing quantitative and qualitative data. Quantitative data were obtained from the Indonesian-validated Collaborative Practice Assessment Tool (CPAT) questionnaire. CPAT in Indonesian language has been validated in previous research by Findyartini, et al. in 2019 in Indonesian population. The questionnaire was internally validated with the study population with Cronbach alpha of 0.812. All health care professionals meeting the selection criteria were enrolled for the quantitative study. The questionnaire was given to 152 health professionals enrolled as research subjects, including nutritionists, nurses, doctors, pharmacists, and medical rehabilitation specialists serving in Dr. Wahidin Sudirohusodo Hospital for >3 years. Five participants with highest and lowest CPAT score from each profession were invited for FGD entitled "Exploring factors involved in interprofessional collaboration in Wahidin Sudirohusodo General Hospital" and divided into 2 groups according to the CPAT score. The score from each subscale in the questionnaire is obtained for each research subjects and the median is compared among each profession group using Kruskall-Wallis test significant to a p value of <0.05. Qualitative data as recording transcript is acquired from FGD; the transcript was then coded into several general themes by 2 of the authors and was discussed using thematic analysis using MaxQDA. Results: Research subjects were predominantly women (121 respondents (79.6%)), 32.9% were nurses, and most of the healthcare professional (81 subjects (55.1%)) have been working for >10 years. Among profession groups (Doctors, Pharmacists, Medical Rehabilitation Specialists, Nutritionists, and Nurses), difference in score distribution (p<0.05) was found in relationships among team members (40 vs 39 vs 39.5 vs 36 vs 42, p<0.001), barriers to team collaboration (10 vs 18.5 vs 14 vs 18 vs 10, p<0.001), and leadership (20 vs 20 vs 23 vs 20 vs 20, p 0.045). From the FGD, factors influencing interpersonal collaborative practice are leadership factors, system/rule factors, and personal factors. Conclusion: This research showed that personal, system/organizational and leadership factors influence the implementation of interprofessional collaboration. In this study, there is a different perception regarding relationships among team members, barriers to team collaboration, and leadership among profession group.

Geospatial analysis of type 2 diabetes mellitus and hypertension in South Sulawesi, Indonesia.

The spatial variation of type 2 diabetes mellitus (T2DM) and hypertension and their potential linkage were explored in South Sulawesi Province, Indonesia. The Global Moran's I and regression analysis were utilized to identify the characteristics involved. The methods were performed based on T2DM and hypertension data from 2017 and 2018 acquired from Social Health Insurance Administration in Indonesia. The spatial variation of T2DM and hypertension showed that the prevalence rate of T2DM and hypertension tends to occur randomly (p = 0.678, p = 0.711, respectively). By utilizing Generalized Poisson Regression Analysis, our study showed a significant relationship between T2DM and hypertension (p ≤ 0.001). This research could help policy makers to plan and support projects with the aim of overcoming the risk of T2DM and hypertension.

Colorectal cancer patients' outcome in correlation with dietary and nutritional status: a systematic review.

Colorectal cancer (CRC) is one of the most common cancers worldwide and it involves various biomolecular and cellular levels. CRC has possibly happened due to aging, urbanization, and diet. Different foods have varying effects on the gastrointestinal cells, that's why additional research is necessary to create effective medical interventions. This review aimed to evaluate the correlation between dietary and nutritional status on the outcome of CRC patients. Study results showed that a healthy diet such as fruit and vegetables is the best diet for improving colorectal cancer outcomes. Moreover, nutritional status affected CRC patients' outcomes, where high BMI increases the risk of having CRC. However, low BMI was associated with CRC progression and poor quality of life.

Green algae Caulerpa racemosa compounds as antiviral candidates for SARS-CoV-2: In silico study.

Green algae (Caulerpa racemosa) are known to contain bioactive compounds which are hypothesized to have antiviral activities against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of coronavirus disease 2019 (COVID-19) pandemic. The aim of this study was to analyze the anti-SARS-CoV-2 potential of compounds extracted from the green alga Caulerpa racemosa using in silico analysis. The extract was obtained through maceration with 96% ethanol and the compounds present in the extract were identified through gas chromatography-mass spectroscopy (GC-MS). The binding affinities were analyzed in silico using the PyRx application and visualized in the PyMOL software. GC-MS analysis of Caulerpa racemosa extract showed 92 spectral peaks, each of which was assigned to a bioactive compound. Of the six compounds with a strong binding affinity, n-[1-(1-adamantan-1-yl-propyl)-2,5-dioxo-4-trifluoromethyl-imidazo lidin-4-yl] 4-methoxy-benzamide had the lowest score (-8.1 kcal/mol) against the SARS-CoV-2 3C-like protease binding site, similar with that of remdesivir. The molecular dynamics calculations demonstrated that root means square deviation values of the selected inhibitors remained stable throughout a 15-nanosecond simulation. In conclusion, the in silico analysis suggests that Caulerpa racemosa extract is a potential antiviral candidate against SARS-CoV-2.

Angiotensin-converting enzyme gene polymorphisms, blood pressure and pulse pressure in subjects with essential hypertension in a South Sulawesi Indonesian population.

AIM: to investigate the potential association between the ACE gene polymorphism, essential hypertension and pulse pressure. METHODS: the study included 99 non-hypertensive and 104 hypertensive subjects. Hypertension is defined as systolic blood pressure 140 mmHg and/or diastolic blood pressure 90 mmHg. Pulse pressure refers to the differences between the systolic blood pressure and diastolic blood pressure. DNA amplication to examine ACE I/D polymorphism was conducted by Rigat-modification PCR method. RESULTS: this study showed no significant difference in genotype distribution and allele frequency between two groups. We found PP >60 mmHg is different between ACE gene genotype. Genotype DD has a risk of 1.8 times of having PP >60 mmHg than ID genotype while DD genotype has a risk of 4.4 times of having PP >60mg than II genotype. CONCLUSION: this study does not support that the I/D polymorphism at ACE gene locus associated with hypertension in Makassar, South-Sulawesi, Indonesia. However, there were a significant correlation with pulse pressure independent from blood pressure.

Analysis of mRNA and protein kidney injury Molecule-1 (KIM-1) expression in a kidney model during the initiation phase of ischemia reperfusion injury.

BACKGROUND: Kidney injury molecule-1 (KIM-1) is a transmembrane glycoprotein expressed predominantly on the proximal tubular epithelium. OBJECTIVE: We wanted to see if there was a critical time for increased tubular damage and its related biomarker, KIM-1 mRNA, and protein expressions during the first 24 h of ischemia-reperfusion injury. METHOD: An Experimental research used five male Rattus Norvegicus rats in each group. Bulldog clamp was used to clamp renal arteries and veins to create renal ischemia. Immunohistochemistry was used for the analysis of KIM-1 protein expression. While Tubular Injury Score was examined by Histopathology. RT-PCR was used for KIM-1 mRNA expression. RESULTS: Tubular Injury Score (TIS) was significantly higher in ischemia than control. TIS remained similar after IR 30 min, peaked at IR 2 h, and decreased to the level of IR 30 min at IR 24 h.The KIM-1 mRNA expression was also higher in ischemia than in control. Similarly, KIM-1 mRNA expression increased more after IR 30 min, IR 2 h, and IR 24 h.The KIM-1 protein expression was higher in ischemia than in control. KIM-1 protein increased more after IR 30 min, IR for 2 h, and remained similar at IR for 24 h.KIM-1 mRNA and protein expressions at IR 2 h were significantly different compared to ischemia but not significantly different compared to that in IR 24 h. CONCLUSIONS: KIM-1 mRNA and protein expressions increased within 24 h IR with the critical time was in the 2 h IR.

Review: Correlation between bladder obstruction with bladder function and erectile dysfunction in mice.

Bladder obstruction, including due to benign prostate enlargement (BPH), will trigger its anatomy and physiological function changes. Men with BPH have a 6 times higher risk of erectile dysfunction than those without BPH. Morphological and functional changes in subjects with partial bladder outlet obstruction (pBOO) occur differently depending on the duration of pBOO that has been experienced. The underlying pathophysiology of BPH is closely related to erectile dysfunction. Anatomically, functionally, and psychologically changes due to BPH will also have an impact on sexual function. Chronic pBOO causes lower urinary tract symptoms (LUTS) through a complex pathophysiological pathway. LUTS and bladder obstruction can lead to erectile dysfunction. The severity of LUTS and sexual dysfunction is inversely related to the quality of life. The treatment of LUTS symptoms will also enhance sexual function.

Point-of-Care Saliva Osmolarity Testing for the Screening of Hydration in Older Adults With Hypertension.

OBJECTIVES: Older adults have an elevated risk of dehydration, a state with proven detrimental cognitive and physical effects. Furthermore, the use of diuretics by hypertensive patients further compounds this risk. This prospective study investigated the diagnostic accuracy of point-of-care (POC) salivary osmolarity (SOSM) measurement for the detection of dehydration in hypertensive adults with and without diuretic pharmacotherapy. DESIGN: Prospective diagnostic accuracy study. SETTING: Home visits to patients recruited from 4 community health centers in West Sulawesi, Indonesia. PARTICIPANTS: A total of 148 hypertensive older adults (57 men, 91 women). The mean ages of male and female patients were 69.4 ± 11.4 and 68.1 ± 7.8 years, respectively. METHODS: Hypertensive adults were divided into 2 groups based on the presence of diuretics in their pharmacotherapeutic regimen. First-morning mid-stream urine samples were used to perform urine specific gravity (USG) testing. Same-day SOSM measurements were obtained using a POC saliva testing system. RESULTS: Both USG (P = .0002) and SOSM (P < .0001) were significantly elevated in hypertensive patients with diuretic pharmacotherapy. At a USG threshold of ≥1.030, 86% of diuretic users were classified as dehydrated compared with 55% of non-using participants. A strong correlation was observed between USG and SOSM measurements (r = 0.78, P < .0001). Using a USG threshold of ≥1.030 as a hydration classifier, an SOSM threshold of ≥93 mOsm had a sensitivity of 78.6% and a specificity of 91.1% for detecting dehydration. CONCLUSIONS AND IMPLICATIONS: Hypertensive patients on diuretics have significantly higher first-morning USG and SOSM values, indicating a higher likelihood of dehydration relative to those on other classes of antihypertensive medication. POC SOSM assessment correlates strongly with first-morning USG assessment, and represents a rapid and noninvasive alternative to urinary hydration assessment that may be applicable for routine use in populations with elevated risk of dehydration.

Benefits and challenges in the implementation of virtual laboratory simulations (vLABs) for medical biochemistry in Indonesia.

The pandemic caused major shifts in the delivery of education worldwide. In the teaching of medical biochemistry, the greatest impact was towards the delivery of traditional laboratory simulations. In this study, we highlight the benefits and barriers encountered in the use of virtual laboratories (vLABs) to substitute traditional laboratory practicals. The subjects were a class of 271 medical students at the Faculty of Medicine, Hasanuddin University, all freshman undergoing the Biomedicine Block. The study assessed the use of a commercial vLAB on antibodies and blood typing procedures, which were implemented using our four-step model of vLAB implementation. Collected data include the lecturer-assigned pre- and post-test result, built-in vLAB assessment result of the student first and best attempts, a student perception questionnaire based on a 5-point Likert scale, and an open ended questionnaire regarding student perceptions of the advantages and disadvantages of the vLAB. We observed a remarkable increase of lecturer assigned pre- and post-test scores and built-in first and best attempt scores (p < 0.0001, Wilcoxon signed rank test). A majority of students reported increased motivation when using the vLABs, and favored the ability of mastery through repetition. However, technical and language barriers were highlighted by students during the vLAB implementation. We demonstrate a successful implementation of commercial vLABs in a cohort of non-native English speakers using our four-step approach. Implementation requires strong support from faculty to address technical and language barriers that arise during use of vLABs.

High-fat diet increases the level of circulating Monocyte Chemoattractant Protein-1 in Wistar rats, independent of obesity.

INTRODUCTION: Low-grade chronic inflammation has emerged as a key pathogenic link between high-fat diet (HFD)-induced obesity and the increased risk of chronic diseases. Evidence has shown that HFDs may induce inflammation in the central nervous system and peripheral tissues. Monocyte Chemoattractant Protein-1 (MCP-1) is a product of various cells that is known to be an inflammatory marker. This study investigated whether a HFD could induce obesity and increase the level of MCP-1 in Wistar rats. METHODS: The Wistar rats were randomized into two groups: normal diet (ND) and HFD (n = 12 per group). Both groups were fed for 8 and 16 weeks, thus dividing the rats into 4 arms: ND8, ND16, HFD8, and HFD16 (n = 6 per sub-group). Obesity in rats was measured using the Lee index. Blood samples were taken to measure the level of MCP-1. RESULTS: Our results showed that obesity did not occur in the group with a normal diet (ND8 and ND16). However, in the HFD group (HFD8 and HFD16), 4 of the 6 rats became obese. However, MCP-1 was significantly higher among non-obese rats in the HFD group compared with the ND group (p < 0.001). CONCLUSION: HFDs have been shown to increase the risk of obesity. In addition, increases in circulating MCP-1 were significantly different between Wistar rats given a HFD compared with the ND group.

Impact of age to ferritin and neutrophil-lymphocyte ratio as biomarkers for intensive care requirement and mortality risk in COVID-19 patients in Makassar, Indonesia.

Inflammation plays a substantial role in COVID-19 pathophysiology. Ferritin and neutrophil-lymphocyte ratio (NLR) are significant prognostic biomarkers used in COVID-19 patients, although they are affected by other factors such as comorbidities and age. Aging changes the immune system through immunosenescence and inflammaging; however, there are limited number of studies evaluating its effect on ferritin and NLR as part of the complete assessment for intensive care requirement and mortality risk. A single-center retrospective cohort study of 295 COVID-19 patients was performed at the Siloam Hospitals Makassar, South Sulawesi, Indonesia from April to August 2020. After admission, all patients were followed up for clinical outcomes. Patients were grouped into strata based on age (<50 years vs. ≥50 years) and risk groups (low-risk ferritin vs. high-risk ferritin; low-risk NLR vs. high-risk NLR). The endpoints of the study were the intensive care requirements and mortality. Among the 295 COVID-19 patients, 264 survived and 31 deceased. Ferritin and NLR had higher area under curve (AUC) values than other inflammatory parameters and had significantly different outcomes in both mortality and intensive care requirement groups. The combination of ferritin and NLR showed higher AUC values for intensive care requirement and mortality (AUC, 0.783; 95% confidence interval, 0.703-0.864). Multivariate analysis showed that both endpoints were strongly affected by age, ferritin level, and NLR. Age significantly multiplied clinical endpoints in low-risk group patients but not in high-risk group patients. The combination of ferritin and NLR had a better predictive value for intensive care requirement and mortality risk. However, age strongly affects clinical outcome in low-risk groups of both ferritin and NLR groups; hence, it should be considered as an early predictive factor of COVID-19 disease progression.
