Highlights: This article presents an understudied topic of nursing workloads in a hemodialysis unit and concludes that directly and indirectly productive activities occupied the majority of the nurses' working time. An analysis using the Workload Indicators of Staffing Need produced a general report that may prompt re-evaluation of nursing staff requirements and policy-making for workload distribution. Abstract The number of hemodialysis patients continues to increase almost every month, while the number of nurses in the Hemodialysis Unit at Rasyida Renal Specialist Hospital, Medan, Indonesia, remains constant. This situation has increased the nurses' workload and responsibilities. Therefore, it is necessary to examine the balance between the workload and the number of required nursing staff in the Hemodialysis Unit at Rasyida Renal Specialist Hospital. This study aimed to identify the optimal number of nursing staff required in the Hemodialysis Unit at the hospital in 2022. This study used a mixed-methods approach using the Workload Indicators of Staffing Need (WISN) method. This study included 44 nurses working in the Hemodialysis Unit at Rasyida Renal Specialist Hospital. Primary data included questionnaires, observations, and interviews during working hours, while secondary data included document reviews and staffing data. WISN calculations showed that the Hemodialysis Unit required a total of 65 nursing staff. In other words, an addition of 21 nursing staff was needed to meet the current workload. In conclusion, the current human resources available are not sufficient, and the workload is beyond the capacity of the nursing staff at the hospital.

Red dragon fruit (Hylocereus polyrhizus) is a tropical fruit that is currently cultivated in all tropical parts of the world. It is popular to consume its fruit flesh, while the peel is often thrown away. This red dragon fruit peel (RDFPE) is known to possess lots of phytochemical compounds with multitudes of usage, amongst them as an analgesic and antipyretic. Therefore, the active compounds of RDFPE play an important role in the natural product. This study aims to observe and analyze the analgetic and antipyretic activity possessed by red dragon fruit peel. This study is an in-vivo experiment on 25 white male rats divided into five groups, in which each group receive Na CMC, acetaminophen, and the other three groups will receive three different doses of RDFPE (500 mg/kg, 750 mg/kg, and 1000 mg/kg), respectively. Acetic acid writhing and tail immersion methods were performed to induce inflammation and Brewer’s yeast injection performed induced pyrexia. In the investigation of the acetic acid writhing test, the intervention was administered before induction, and for the tail immersion test, induction was given before and after the intervention was administered. Meanwhile, in brewer’s yeast-induced pyrexia, the rectal temperature was measured before induction, 24 hours after induction, and each hour for five four after the intervention; intervention was administered 24 hours after induction. This study found that RDFPE at the dose of 750 mg/kg and 1000 mg/kg are effective as an analgesic by reducing the average writhing and delaying the tail retraction of the experiment subject and also effective as an antipyretic by reducing the elevated temperature of the experiment subject (p

Background: The excessive use of chemotherapy drugs such as doxorubicin might induce cardiovascular diseases.

Type 2 Diabetes Mellitus (Type 2 DM) is a metabolic disorder group with mechanisms that include hyperglycemia, insulin resistance and hyperinsulinemia. Type 2 DM has a close association with IGF-1, where the active form of the IGF-1 becomes elevated by reason of the fact that hyperinsulinemia inhibits the production of IGF-binding proteins (IGFBP) 1/IGFBP 2. The active form of IGF-1 has the ability to promote cell proliferation and inhibit apoptosis, hence becomes one of the risk factors for cancer cell growth. This was an analytical study conducted in August at the Harapan Bunda Clinic, Medan, Indonesia to determine the difference between the IGF-1 level and blood glucose level in type 2 DM patients in different age groups. Twenty subjects with Type 2 DM participated in this study and were divided based on their age into 35-50 years old or Group 1 and 51-65 year old group or Group 2. The IGF-1 levels in both groups were compared and analyzed using the T-test dependent method. Results showed that the IGF-1 and blood glucose levels were higher in Group 1 (35-50 years old) when compared to Group 2 and the difference was significant. The change in the IGF-1 level in diabetic patients cannot be determined only by the blood sugar level.

Cirrhosis is a serious hepatic disease that occurs worldwide and is caused by progressive fibrosis in the liver. Free radicals are the major cause of reactive oxygen species (ROS) generation, which affects the balance of the liver metabolism. Piper crocatum, commonly called red betel, is widely used in ethnomedicine because it has biological capabilities, including antioxidant and anti-inflammatory properties. The present study was undertaken to examine the possibility of hepaprotective activity of red betel extract on acetaminophen (APAP)-induced HepG2 cells as the cirrhosis in vitro model. Assessment of red betel extract (RBE) was performed using the colorimetric method for the quantification of LDH, AST, and ALT. As preliminary study, a cytotoxicity assay was performed at various RBE concentrations (100.00; 50.00; 25.00; 12.50; 6.25; 3.13 μg/ml) using an MTS assay to decide the safe concentration based on cell viability. The RBE treatment did not affect cell viability, even at a high concentration (100 µg/ml, p > 0.05). RBE at concentrations 25 and 100 µg/ml successfully reduced LDH, AST, and ALT activities in the hepatotoxic model in a dose-dependent manner. In the APAP-induced hepatotoxicity model, RBE positively indicated a hepatoprotective effect and cell amelioration by a decrease in hepatotoxic markers.

Acetaminophen (APAP) is a widely used analgesic, but it may cause liver injury (hepatotoxicity) via oxidative stress that induced by N-acetyl-p-benzoquinone imine (NAPQI) in long term usage or overdose. Multiple inflammatory mediators were also found to contribute for this effect. Many medicinal plants was known for its antioxidant and anti-inflammatory activities and one of them is Red betel (Piper crocatum Ruiz and Pav) from Indonesia. In this study, the red betel leaves extract (RBLE) protective effect against APAP-induced HepG2 cells was determined. APAP-induced HepG2 as hepatotoxicity cell model was treated with RBLE at 25 and 100 μg/mL. Protective effects of RBLE toward hepatotoxicity were evaluated by several parameters: tumor necrosis factor-α (TNF-α) concentration, reactive oxygen species (ROS) level, live cells percentage, apoptotic cells percentage, necrotic cells percentage, death cells percentage, CYP2E1 and GPX gene expression. The RBLE treatments (both 25 and 100 μg/mL) increased CYP2E1 and GPX gene expression also live cells percentage, while decreased ROS level, TNF-α concentration, also the percentage of death and necrotic cells. Red Betel leaves ethanol extract has hepatoprotective effect via anti-inflammatory, anti-necrotic, and antioxidant potency in liver injury model.

Cardiotoxicity is a condition where damages caused by toxic chemical exposure are observed in heart and blood vessels. Doxorubicin is the most common chemotherapy agents for various types of cancer therapy. However, doxorubicin is converted into doxorubicinol known to trigger cardiac disfunctions and release of several cardiac biomarkers, such as CK-MB and LDH. Turmeric is known to be an alternative medical treatment that has the effect of neutralizing oxidative stress. This study aimed to evaluate CK-MB and LDH levels in doxorubicin-induced rats (20 mg/kgBW) that received turmeric ethanolic extract from curcuma. This was an experimental study conducted in February 2020 in the Faculty of Pharmacy Universitas Sumatera Utara. The rats were divided into six group and each group consisted of wistar albino male rats. The groups were normal (CMC-Na), positive control (Vitamin E 1%+Dox 20 mg/kgBW), negative control (Dox 20 mg/kgBW), treatment I (EEC 100 mg/kgBW+Dox 20 mg/kgBW), treatment II (EEC 300 mg/kgBW+Dox 20 mg/kgBW), and treatment III (EEC 500 mg/kgBW+Dox 15 mg/kgBW). Doxorubicin was given 5 mg/kgBW once a week for four weeks. Results showed that the groups that received 100 mg/kg BW, 300 mg/kgBW, and 500 mg/kgBW of turmeric ethanol extract demonstrated a reducing effect on the biomarkers of cardiac damage, i.e. CK-MB and LDH. Statistically, serum CK-MB and LDH levels at dose 500 mg/kgBW showed no significant differences (p>0.05) with the normal and positive treatment group. In conclusion, turmeric has a cardioprotective effect.

Breast cancer (BC) is the number one cause of deaths from cancer in women. Metastasis in BC is caused by immunosurveillance deficiency, including impairment of Natural Killer (NK) cell maturation, low NK activity, and decreasing cytotoxicity. This study was performed to improve activating receptors and cytotoxicity of NK cells using interleukin 15 (IL15) against BC cells. Human recombinant IL15 was used to induce NK cells. To evaluate the potential of IL15 in inducing NK cells, we measured the activating and inhibiting receptors (NKG2D, NKG2A), apoptotic potency of NK cells on BC cells (MCF7) using transwell assay. The IL15 inducer on the NK cell were measured NKG2D, NKG2A gene expression with quantitative polymerase chain reaction (qPCR), (GzmB) secretion using ELISA, apoptotic gene expression of MCF7 using qPCR. IL15 increased NKG2D expression 4.01-9.13%, but IL15 could not affect toward NKG2A expression on NK cells. IL15-activated NK cells, inhibited BC cells proliferation, induced apoptotic BC cells 25.89-32.19%, induced apoptotic genes of BC cells bax, p53. IL15 increase NK activating receptor (NKG2D), inhibit BC cells proliferation, induce apoptotic percentage and induce apoptotic gene expression.

Background: Rosa damascena L. is the most notable species of the Rosaceae family in the world, and has been used in food, cosmetics, and the pharmaceutical industry. Bioactive compounds in this flower are known to have several activities, such as antioxidant, antimicrobial, and anti-inflammatory. In this study, the antioxidant and collagenase inhibitory activities of R. damascena L. petal and receptacle extracts were evaluated. Methods: Ethanolic extraction of R. damascena L. petals (EERP) and R. damascena L. receptacles (EERR) were obtained, and bioactive compounds (flavonoids, phenolics, alkaloids, steroids, tannins, terpenoids, and triterpenoids) were classified by phytochemical screening. Antioxidant activities were analyzed by Ferric Reducing Antioxidant Power (FRAP) assay, while anti-collagenase analysis was examined through the inhibition of collagenase. Results: Phytochemical test revealed the presence of flavonoids, phenolics, alkaloids, steroids, triterpenoids, triterpenes, and tannin. EERP showed higher FRAP activity (164.23 ± 1.34 μM Fe(II)) than EERR (12.85 ± 6.19 μM Fe(II)). EERP also had higher inhibitory activity of collagenase (IC 50 = 115.48±1.78 µM/mL) compared to EERR (IC 50 = 141.96±6.13 µM/mL). Conclusions: R. damascena L. petal and receptacle ethanol extracts contain several components, such as phenolics, flavonoids, alkaloids, tannins, terpenes, triterpenoids, and steroids. These extracts exhibit antioxidant activity and collagenase inhibition. R. damascena L. petal extract showed higher antioxidant activity through FRAP assay and inhibitory activity of collagenase than R. damascena L. receptacle extract.

Liver injury occurs due to continuous exposure to chemical or biological hazards. Eugenol (EUG), a phenolic compound derived from red betel (Piper crocatum) leaves, has multivalent effects, primarily on antioxidant and antibacterial applications. The conducted research sought to investigate the safeguarding activities of EUG on hydrogen peroxide (H2O2)-induced toxicity of human liver HepG2 cells by examining homeostasis, interleukin 10 (IL-10), malondialdehyde (MDA) levels, reactive oxygen species (ROS) level and cytochrome P450 family 1 subfamily B member 1 (CYP1B1) gene expression. The H2O2-induced hepatotoxic cells, which served as a positive control, were treated with EUG. The measurements for IL-10 and MDA levels were made using enzyme-linked immunosorbent assay (ELISA), flow cytometry was employed for ROS level, and reverse transcription-quantitative real-time PCR (RT-qPCR) was used for CYP1B1 gene expression assay. EUG 6.25; 25 µg/mL increased IL-10 levels at 55.33 and 47.52 pg/mL compared to the positive control at 21.66 pg/mL. EUG 6.25; 25 µg/mL lowered MDA levels at 679.07 and 651.60 ng/mL compared to the positive control at 845.33 µg/mL. EUG 6.25; 25 µg/mL suppressed ROS level at 15.83 and 19.40% compared to the positive control at 24.10%. EUG 6.25; 25 µg/mL also up-regulated CYP1B1 gene expression. In conclusion, EUG exhibited excellent hepatoprotective effects in hepatotoxic cells model by maintaining ROS homeostasis, increasing IL-10, decreasing MDA levels, and upregulating CYP1B1 gene expression.
