Abstract

BackgroundContrast media administration during diagnostic and invasive procedures in high risk patients for nephrotoxicity is a common problem in clinical practice. Radiological procedures using intravascular iodinated contrast injection media have been widely used for therapeutic purposes. Contrast-induced nephropathy (CIN) is a serious complication of angiographic procedures and results from administration of contrast media (CM), which increases morbidity and mortality rates. Case Description                                                                                                                                                                                                               We present these 10 cases with high risk of CIN and diverse characteristics. A new generation iso-osmolar CM (iodixanol) was administered in these cases. Three of the cases experienced CIN events, where one patient experienced an improvement in his condition, but two other patients experienced complications and eventually died due to the underlying disease. The other 6 cases did not experience CIN after receiving CM, which was due to better preparation beforehand. One patient with a history of regular hemodialysis, underwent immediate post-operative dialysis with CM, and no evaluation of the incidence of CIN was required. Conclusion Of the 10 cases observed, 3 of them experienced CIN which was caused by the severity of the patient’s condition and lack of preparation time before the CM procedure. Management of CIN is complex, starting from the pre-treatment evaluation until 72 hours or more after the CM procedure. This case series suggests that even new generation CM (including iodixanol) may be severely nephrotoxic, when administered to high risk patients. The amount of CM given must be below the maximum limit and adjusted to the patient’s condition. Additionally, we review the complex mechanisms involved in management of CM nephrotoxicity.

Abstract

BACKGROUNDMalaria remains one of the major causes of death worldwide. Holothuria scabra has a high nutritional content and many biological effects. The development of alternative anti-malarial drugs is necessary, considering that resistance to the newest anti-malarial drugs has been reported. This research study aimed to determine the anti-malarial effects of Holothuria scabra in mice infected with Plasmodium berghei. METHODSThis was a post-test only control group study conducted on 24 Balb/c mice. Peter’s four-day suppressive test was employed to ascertain the claimed anti-plasmodial effect of the simplicia. Following inoculation with P. berghei, all 24 mice were infected and randomized into 4 groups, namely 3 treatment groups and 1 control group. The control group was given carboxymethyl cellulose, two of the treatment groups were given doses of 10 and 100 mg/kg BW Holothuria scabra, respectively, using Peter’s four-day suppressive test, while the remaining treatment group received a dose of 100 mg/kgBW using the prophylactic method. Data were analyzed using One way ANOVA. RESULTSThe results showed by using both the four-day suppressive test and the prophylactic method, that Holothuria scabra has antimalarial activity. Holothuria scabra at a dose of 100 mg/kg BW was significantly effective in decreasing the percentage of parasitemia (p=0.000) and tended to inhibit the growth of Plasmodium berghei in mice (p=0.054). CONCLUSIONThis study demonstrated that Holothuria scabra possesses anti-plasmodial activity in mice. Hence, the sea cucumber could serve as a potential source of a newer antimalarial agent.

Abstract

BACKGROUNDAnopheles (An.) sp. transmits Plasmodium parasites that cause malaria. In its life cycle in the mosquito’s body, Plasmodium passes through 2 mosquito organs, namely the salivary glands and midgut. The bacterial community (symbiont bacteria) in these organs has been known to influence and/or inhibit the development of the Plasmodium life cycle by producing specific proteases. This research aims to isolate and characterize symbiotic bacteria with proteolytic activity from 2 important malaria vectors in Indonesia: An. sundaicus and An. vagus. METHODSA total of 183 bacterial originating from the salivary glands and midgut were successfully isolated. Initial screening was carried out based on morphological differences, followed by purification of the selected isolates to obtain single colonies. The selected isolates were then subjected to an initial proteolytic ability test using skim milk agar media. Only isolates with proteolytic activity were further characterized with the 16SrDNA molecular marker. The isolates were pabs5 from the salivary glands and pabs3 from the midgut of An. vagus, while pdbs3 and ecbs4 were isolates from the salivary glands and midgut of An. sundaicus. RESULTSMorphological and molecular characterization showed that both pabs5 and pabs3 isolates were Pseudomonas(Ps.) aeruginosa, while ecbs4 was Enterobacter cloacae and pdbs3 was Pantoea dispersa. These species werefirst discovered in Anopheles vagus and Anopheles sundaicus. CONCLUSIONThe ability of Ps. aeruginosa and Pantoea dispersa to produce proteases indicated their potential role in the exploration of new strategies to control mosquito vectors that transmit pathogens.

Abstract

BackgroundMelasma is a highly prevalent chronic pigmentary disorder. The pathogenesis is unknown but melasma often occurs in photo-exposed areas, e.g., cheeks, upper lip, chin, and forehead. Tranexamic acid (TA), a plasmin inhibitor, aids in the inhibition of UV-induced plasmin activity and melanogenesis, making it a favorable therapeutic option for melasma. Tranexamic acid may be administered through various routes, e.g., topical. This study aimed to compare the efficacy of topical 10% versus 5% TA in women with melasma. MethodsThis double-blind randomized controlled trial included 16 females with epidermal type melasma who were randomized into two groups to receive either topical 10% TA (n = 8) or 5% TA (n = 8) applied twice daily for eight weeks. Prior to intervention and at 8 weeks after intervention, the intensity and extension of melasma were assessed based on melasma area and severity index (MASI) score and pigmentation score. ResultsMean MASI and pigmentation scores in both treatment groups were similar at base-line (p>0.05). The reduction in MASI and pigmentation scores in the topical 10% TA and 5% TA groups was similar and statistically not significant after 4 and 8 weeks of treatment (p>0.05). There were no drug-related adverse reactions or complications. ConclusionThis study demonstrated that topical 10% TA and 5% TA were effective in treating women with melasma. The utilization of topical 5% TA for melasma is a promising alternative therapeutic option without the need to increase the concentration of the formulation.

Abstract

BackgroundThe recurrence of antibacterial infections after antibiotic treatment necessitates the investigation of alternative therapies against uropathogens. Cissampelos pareira is an Ethiopian medicinal plant that has been used for centuries by traditional healers to treat various diseases. The plant is selected on the basis of its traditional use in treating urinary tract infections by the local community. The objective of this study was to determine traditionally used anti-uropathogenic properties of C. pareira root extracts. Methods C. pareira plant roots collected from Pawe Woreda were shade-dried, powdered, and extracted using chloroform, hexane, acetone, methanol, and ethanol, respectively. The antibacterial activities with different concentrations of the crude extracts were determined using the disc diffusion assay. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of the crude extracts were determined using a two-fold broth dilution method. ResultsThe antibacterial activities of the root extracts against tested organisms as shown by inhibition zone diameters ranged from 7.0±0.1 to 20.8±1.0 mm. The highest inhibition was recorded from the ethanol extract while the lowest was from the chloroform extract.  The MIC and MBC values ranged from 12.5 to 50 µg/mL and 25 to 100 µg/mL, respectively. Ethanolic and methanolic C. pareira root extracts showed the presence of antibacterial compounds (alkaloids, flavonoids, tannins, terpenoids and steroids). ConclusionThis study showed that C. pareira root serves as a potential source for developing new antibacterial drugs against bacteriuria. However, nontoxicity evaluation is recommended for the use of herbals as therapeutic agents in pharmacy.

Abstract

Background Diabetic retinopathy (DR) constitutes a primary cause of blindness across all age groups. Ophthalmologists examine fundus images (FI) to detect and classify stages of DR. Development of deep learning can help clinicians to attain a larger volume in screening and diagnosing diabetic retinopathy, thereby decreasing the burden of visual impairment caused by DR. This study aimed to classify DR using ensemble convolutional neural networks (CNN) architectures. Methods We used data from the Indian Diabetic Retinopathy Image Dataset which consist of typical diabetic retinopathy lesions at pixel level. The dataset contains typical diabetic retinopathy structures as well as normal retinal structures and is divided into three parts: segmentation, classification, and location. There are 516 original color fundus images in the classification used as training set (413 images) and testing set (103 images). We used ensemble CNN architectures to classify diabetic retinopathy as no DR, mild non-proliferative DR (NPDR), moderate NPDR, severe NPDR and proliferative DR (PDR) based on fundus image. Results In this study we successfully created a model with ensemble CNNs to detect DR based on fundus images with area-under-the-curve, sensitivity, and specificity of 0.88, 0.89, and 0.90, respectively, which is on par with the most modern methods. Conclusion Based on the results, this model performs quite well in early detection of diabetic retinopathy and can be used to develop a more accurate model for detecting and classifying diabetic retinopathy. This model can also be used in assisting mass screening at lower cost without reducing diagnostic effectiveness.

Abstract

BACKGROUNDNicotine induces oxidative stress in human gingival fibroblasts (HGF) and stimulates the production of cytokines that trigger inflammation. Abrus precatorius L. (AP) leaves contain antioxidants with anti-inflammatory properties that can prevent the formation of free radicals and reduce tissue damage due to inflammation. This study aimed to determine the effect of ethanolic extract of AP leaves (EAP) on interleukin (IL-6) levels and cyclooxygenase-2 (COX-2) gene expression in gingival fibroblasts exposed to nicotine. METHODSCells were randomized into six treatment groups and clustered into the non-treatment control group (NTC), solvent control (SC), nicotine control (NC), and groups treated with nicotine and EAP at doses of 9.375 µg/mL, 18.75 µg/mL, and 37.5 µg/mL, respectively, for 24 hours. IL-6 levels were examined using the Elisa method, while COX-2 gene expression was assessed using PCR. Data were analyzed using Oneway ANOVA and the Kruskal Wallis test. RESULTSIL-6 levels and COX-2 expression were considerably higher in the nicotine control group. Conversely, the cell groups treated with nicotine and EAP had substantially decreased levels of both inflammatory markers IL-6 and COX-2 (p=0.029) across all EAP dose levels compared to the nicotine control group. The highest reduction in response was observed at the dose of 9.375 ìg/mL EAP. CONCLUSIONThese results highlight the potential of Abrus precatorius L. in relieving nicotine-induced inflammation in smokers. By suppressing the production of inflammatory mediators IL-6 and COX-2 in HGF, EAP presents a promising avenue for further in vitro research.

Abstract

BackgroundStretching includes movements that provide joint range of motion, increase the flexibility of muscles, joints, ligaments, and the speed of musculoskeletal communication, which are applied to increase performance in the main part of the training. Anaerobic properties are among the most important determinants of performance in athletes. Therefore, the objective of this study was to investigate the effects of five different stretching exercises on anaerobic performance (speed and agility parameters) in recreationally active women. MethodsA study of within-subject experimental design was conducted involving 30 recreationally active females aged 23.76 ± 1.50 years. Five different protocols (NS: no stretching; SS: static stretching; DS: dynamic stretching; SDS: static + dynamic stretching; DSS: dynamic + static stretching) were used to measure performance parameters after stretching exercises. After each stretching exercise, the 10 and 20 m sprint, Illinois agility test, and reactive agility test were used to determine anaerobic performance. Repeated measures analysis of variance (ANOVA) was employed for the analysis. ResultsA notable difference was observed in the 10 m and 20 m performance of recreationally active women after five different stretching protocols (p<0.05). When looking at the agility test values, it was found that a significant difference existed (p<0.05). DS showed the best performance in all tests. ConclusionAccording to these results, in recreationally active women, only SS should be avoided before high or explosive exercises, or the warm-up period should include only DS, or if a combined application is to be made, DS should be applied after SS.

Abstract

BackgroundAcute lymphoblastic leukemia (ALL) is the most common childhood hematologic malignancy. Treatment failure in ALL can be caused by severe and life-threatening complications, including tumor lysis syndrome (TLS). Delay in identifying risk factors and establishing the diagnosis of TLS by clinicians can be fatal. This study aimed to determine the risk factors for TLS in children with ALL. MethodsThis was a retrospective cross-sectional study on 81 children aged 0 to 18 years with ALL. Tumor lysis syndrome comes in two forms: laboratory and clinical. Laboratory TLS occurs if uric acid levels >normal values, potassium >6mEq/L, phosphate >6.5mg/dl, and calcium <7mg/dl. Clinical TLS includes an increase in serum creatinine, the presence of heart attacks, sudden death, and seizures. Risk factors for TLS include age, nutritional status, leukocyte count, presence of organ infiltration, presence of mediastinal mass, uric acid level, renal function, and type of chemotherapy regimen. Risk factors were analyzed using simple and multiple logistic regression analyses. A value of p<0.05 indicates a significant risk factor. ResultsTwenty seven patients (33.3%) experienced TLS. Adjusted OR analysis showed that the presence of organ infiltration (aOR 5.42; 95% CI 1.45-20.27; p=0.012), leukocyte count (aOR 8.70; 95% CI 1.67-45.13; p=0.010), and decreased kidney function (aOR 12.21; 95% CI 1.09-136.89; p=0.042) were significant risk factors for TLS. ConclusionDecreased renal function, leukocyte count, and organ infiltration were significant risk factors for TLS. We suggest more vigilant assessment and monitoring to recognize and treat those patients who are at risk of TLS.
