ABSTRACT

BACKGROUND: The deep inferior epigastric perforator flap (DIEP) is a widely known reliable option for autologous breast reconstruction. One common complication of DIEP procedures is fat necrosis. Consequences of fat necrosis include wound healing complications, pain, infection, and the psychological distress of possible cancerous recurrence. Clinical judgment alone is an imperfect method to detect at-risk segments of adipose tissue. Objective methods to assess perfusion may improve fat necrosis complication rates, reducing additional surgeries to exclude cancer and improve cosmesis for patients.

METHODS: The authors performed a retrospective review of patients who underwent analysis of DIEP flap vascularity with or without intraoperative indocyanine green angiography (ICGA). Flap perfusion was assessed using intravenous ICGA and was quantified with both relative and absolute value units of fluorescence. Tissue with observed values less than 25% to 30% relative value units was resected. Postoperative outcomes and fat necrosis incidence were collected.

RESULTS: Three hundred fifty-five DIEP flaps were included in the study, 187 (52.7%) of which were assessed intraoperatively with ICGA. Thirty-nine patients (10.9%) experienced operable fat necrosis. No statistically significant difference in incidence of postoperative fat necrosis was found between the 2 groups (P = 0.732). However, a statistically significant relationship was found between fat necrosis incidence and body mass index as both a continuum (P = 0.001) and when categorized as greater than 35 (P = 0.038).

CONCLUSIONS: Although ICGA is useful for a variety of plastic surgery procedures, our retrospective review did not show a reduction in operable fat necrosis when using this technology.

ABSTRACT

BACKGROUND: Cardiac iron toxicity is a major cause of mortality in transfusion-dependent beta-thalassemia major patients. The main modality for detecting cardiac iron toxicity is MRI T2* with limited availability. This study aims to obtain iron toxicity profiles in transfusion-dependent beta-thalassemia patients; to see a correlation between iron toxicity and cardiac function.

METHODS: We conducted a cross-sectional study at the Adult Thalassemia Polyclinic of Cipto Mangunkusumo Hospital, Indonesia from December 2017 to March 2018. We performed the statistical analysis using Pearson/Spearman Test comparing MRI T2* values with ejection fraction and E/A ratio.

RESULTS: The median of 4-months mean of ferritin levels was 5130 ng/mL. The mean for cardiac T2* was 24.96 ms. Severe cardiac hemosiderosis (mean cardiac MRI T2* < 10 ms) occurred in 11.3% of the subjects. There was weak correlation between serum ferritin with cardiac iron toxicity (r=-0.272, p=0.032) and ejection fraction (r=-0.281, p=0.013). But, there was no correlation between cardiac iron toxicity with ejection fraction and E/A ratio.

CONCLUSION: Serum ferritin correlated weakly with cardiac iron toxicity and cardiac systolic function. Meanwhile, there was no correlation between cardiac iron toxicity with cardiac systolic and diastolic function.

ABSTRACT

BACKGROUND: Autologous platelet-rich fibrin (A-PRF) is an adjunctive method for diabetic foot ulcer (DFU) in addition to glycaemic control and debridement. This study aimed to evaluate the role of A-PRF + hyaluronic acid (HA), A-PRF and sodium chloride 0.9% (control) in DFU wound healing. Nowaday, the use of PRF autologous consider as adjuvant therapy in DFU treatment.

METHODS: This open-label randomized controlled trial was conducted at Koja District Hospital and Gatot Soebroto Hospital from July 2019 to April 2020. DFU patients with wound duration of three months, Wagner-2, and ulcer size < 40 cm2 were recruited and randomly assigned into A-PRF + AH, A-PRF and control group. On day-0, day-3 and day -7, samples and photographs were taken. Samples were analysed with ELISA and photographs were analysed with ImageJ to calculate granulation index (GI). Statistical analysis was performed using SPSS version 20.

RESULTS: Topical therapy with A-PRF + AH was associated with a significant increase in VEGF from day 0 (232.8 pg/mg) vs day 7 (544.5 pg/mg) compared to A-PRF on day 0 (185.7 pg/mg) vs day 7 (272.8 pg/mg), and the controls on day 0 (183.7 pg/mg) vs day 7 (167.4 pg/mg). On evaluation of VEGF swab, there is increasing significantly in A-PRF+HA group compare others group in day -3 ( p=0.022) and day -7 (p= 0.001).In the A-PRF + AH group, there was a significant decrease in IL-6 from day 0 (106.4 pg/mg) vs day 7 (88.7 pg/mg) compared with PRF on day 0 (91.9 pg/mg) vs day 7 (48,8 pg/mg). IL-6 was increased in the control group from day 0 (125.3 pg/mg) vs day 7 (167.9 pg/mg). On evaluation of IL-6 swab, there is decreasing significantly in A-PRF+HA group compare others group in day -7 (p= 0.041).

CONCLUSION: The PRF + HA combination increased angiogenesis and reduced inflammation in DFUs and may represent a new DFU therapy.

ABSTRACT

BACKGROUND: The MacNew heart disease health related quality of life tool is used widely in the cardiac populations to evaluate the impact of disease and intervention including rehabilitation. In addition to the English version, it is also available for several other languages except the Indonesian language. Therefore, the purpose of this study were 1) to translate the MacNew questionnaire from the English version to the Indonesian language and 2) to estimate the preliminary validity and reliability of the Indonesian MacNew for patients with coronary artery disease.

METHODS: Forward and backward translation procedure was used to develop the Indonesian MacNew. The Indonesian MacNew was administered to 24 patients after one week of revascularization surgery. Reliability was assessed by internal consistency and test-retest reliability. To evaluate concurrent validity, the correlation of the compatible domain of the Indonesian MacNew and SF-36 was assessed.

RESULTS: Internal consistency reliability of the Indonesian MacNew was confirmed with Cronbach’s α of the global scale and all three subscales exceeding 0.95. Test- retest reliability was acceptable with intraclass correlation coefficient of 0.66 for the global score. Furthermore, an acceptable concurrent validity was established with statistically significant correlation between Indonesian MacNew and SF-36 (pearson correlation ranging from 0.47 to 0.71).

CONCLUSION: The first results of the Indonesian MacNew indicate acceptable validity and reliability as a measurement tool to assess health related quality of life of Indonesian patients with coronary artery disease.

ABSTRACT

This study investigated the effects of 6 mg/day of astaxanthin supplementation on markers of oxidative stress and substrate metabolism during a graded exercise test in active young men. A double-blind, randomized, counterbalanced, cross-over design was used. Fourteen men (age = 23 ± 2 years) supplemented with 6 mg/day of astaxanthin and a placebo for 4 weeks, with a 1 week washout period between treatments. Following each supplementation period, a fasting blood sample was obtained to measure markers of oxidative stress: glutathione, hydrogen peroxide, advanced oxidation protein products, and malondialdehyde. Participants also completed a graded exercise test after each treatment to determine substrate utilization during exercise at increasing levels of intensity. Glutathione was ∼7% higher following astaxanthin compared with placebo (1,233 ± 133 vs. 1,156 ± 185 μM, respectively; p = .02, d = 0.48). Plasma hydrogen peroxide and malondialdehyde were not different between treatments (p > .05). Although not statistically significant (p = .45), advanced oxidation protein products were reduced by ∼28%. During the graded exercise test, mean fat oxidation rates were not different between treatments (p > .05); however, fat oxidation decreased from 50 to 120 W (p < .001) and from 85 to 120 W (p = .004) in both conditions. Astaxanthin supplementation of 6 mg/day for 4 weeks increased whole blood levels of the antioxidant glutathione in active young men but did not affect oxidative stress markers or substrate utilization during exercise. Astaxanthin appears to be an effective agent to increase endogenous antioxidant status.

ABSTRACT

BACKGROUND: Systemic sclerosis (SSc) is a systemic autoimmune disease involving a multisystem. Modified Rodnan’s Skin Score (MRSS) is a gold standard for measuring skin fibrosis in SSc. In SSc, lung fibrosis disorders, especially interstitial lung disease (ILD), are the leading cause of mortality and often late in diagnosis. High-Resolution Computed Tomography (HRCT) Chest scan is a gold standard for evaluating ILD morphology, but its availability is limited. The degree of skin fibrosis based on MRSS in SSc can predict the presence of ILD in several studies but has not been widely studied in Indonesia. This study aimed to determine the relationship of the ILD morphology based on thoracic HRCT scan with the degree of skin fibrosis based on MRSS in SSc.

METHODS: This study is a retrospective analytic observational study with a cross-sectional design. The subjects of this study are SSc patients who had data of MRSS and HRCT chest scan from July 2019 to March 2020. Statistical analysis uses Spearman’s correlation test.

RESULTS: There were 42 study subjects, consisting of 41 women (97.6%) and one man (2.4%) with an average age of 39.50 years old (age range of 19 years to 60 years old). Correlation test results based on Spearman’s show a moderate correlation between the morphological score of ILD with MRSS with R = 0.429, which is significant (p = 0.005).

CONCLUSION: There is a significant moderate correlation between the morphological scores of ILD based on HRCT chest and the degree of skin fibrosis based on MRSS in SSc.

ABSTRACT

PURPOSE OF THE STUDY: Hypertension is one of the most common comorbidities in COVID-19 pneumonia. However, whether it is an independent factor on the severity and mortality of COVID-19 has not been studied.

STUDY DESIGN: In this study, 736 patients with a PCR-confirmed diagnosis of COVID-19 were included from 12 January 2020 to 25 March 2020. All patients were divided into two groups according to whether or not they were hypertensive. After propensity score matching (PSM) to remove the interference of mismatches in the baseline data, the clinical characteristics and outcomes of angiotensin II receptor blocker (ARB)/ACE inhibitors application were analysed.

RESULTS: A total of 220 (29.9%) patients were hypertensive, and 516 (70.1%) patients were not hypertensive. PSM eliminated demographic and comorbidity differences between the two groups. Of all participants, 32 patients died (4.3% mortality), including 17 out of 220 in the hypertension group (7.7%) and 15 out of 516 in the non-hypertension group (2.9%). The incidence of intensive care unit (ICU) stay in the hypertension group (12.8%) was higher than in the non-hypertension group (5.3%) (p<0.05). Logistic regression analysis showed that hypertension was an independent risk factor for death, not other comorbidities. Kaplan-Meier analysis showed that mortality was higher in the hypertension group than in the non-hypertension group before and after PSM (p<0.05). There was no statistically significant difference in ICU therapy, mortality and hospitalisation time between hypertensive patients with or without ARBs/ACE inhibitors (p>0.05).

CONCLUSION: Hypertension was an independent risk factor for the severity and mortality of patients with COVID-19. ARBs/ACE inhibitors should not be discontinued in hypertensive patients with COVID-19.

ABSTRACT

PURPOSE: Many aspects of the management of neutropenic sepsis remain controversial. These include the choice of empiric antibiotic, the duration of antibiotic therapy and the possibility that very low-risk cases may be managed safely with oral rather than intravenous therapy.

STUDY DESIGN: Retrospective cohort study conducted in a district general hospital serving a population of 148 000 in south west Scotland.

RESULTS: Fifty one patients with cancer, whose neutrophil count was less than 1.0×10⁹/L within 21 days of their last chemotherapy, were admitted as a medical emergency in 2019. All received antibiotic because of presumed neutropenic sepsis. A total of 4 patients had positive blood cultures (group 1), 12 patients had a clinical focus of infection but no clear pathogen (group 2), while 35 patients had neither (group 3). Group 3 patients were more likely to have a solid tumour, less likely to be febrile, had shorter time to neutrophil recovery and higher Multinational Association of Supportive Care in Cancer scores, though not all of these comparisons achieved statistical significance. Median intravenous plus oral antibiotic duration in group 3 patients was 9 days with median hospital stay of 7 days, raising the possibility of overtreatment. Retrospectively, 23 (66%) group 3 patients had MASSC Risk Index greater than 21 suggesting they were at low risk of complications.

CONCLUSIONS: It seems likely that many low-risk neutropenic cancer patients with solid tumours could be managed as effectively and as safely with shorter courses of antibiotic, with oral rather than intravenous antibiotic, as outpatients rather than inpatients and with an overall positive impact on antimicrobial stewardship.

ABSTRACT

The aim of this study was to develop an interventional optical imaging (OI) technique for intraprocedural guidance of complete tumor ablation. Our study employed four strategies: 1) optimizing experimental protocol of various indocyanine green (ICG) concentrations/detection time windows for ICG-based OI of tumor cells (ICG cells); 2) using the optimized OI to evaluate ablation-heat effect on ICG cells; 3) building the interventional OI system and investigating its sensitivity for differentiating residual viable tumors from nonviable tumors; and 4) preclinically validating its technical feasibility for intraprocedural monitoring of radiofrequency ablations (RFAs) using animal models with orthotopic hepatic tumors. OI signal-to-background ratios (SBRs) among preablation tumors, residual, and ablated tumors were statistically compared and confirmed by subsequent pathology. The optimal dose and detection time window for ICG-based OI were 100 μg/mL at 24 h. Interventional OI displayed significantly higher fluorescence signals of viable ICG cells compared with nonviable ICG cells (189.3 ± 7.6 versus 63.7 ± 5.7 au, P < 0.001). The interventional OI could differentiate three definitive zones of tumor, tumor margin, and normal surrounding liver, demonstrating significantly higher average SBR of residual viable tumors compared to ablated nonviable tumors (2.54 ± 0.31 versus 0.57 ± 0.05, P < 0.001). The innovative interventional OI technique permitted operators to instantly detect residual tumors and thereby guide repeated RFAs, ensuring complete tumor eradication, which was confirmed by ex vivo OI and pathology. In conclusion, we present an interventional oncologic technique, which should revolutionize the current ablation technology, leading to a significant advancement in complete treatment of larger or irregular malignancies.

ABSTRACT

BACKGROUND AND PURPOSE: White matter lesions (WMLs) are thought to cause damage to the blood-brain barrier, thereby aggravating bleeding after intravenous thrombolysis. However, the risk factors for symptomatic cerebral haemorrhage after thrombolysis are still unclear. This study explored the risk factors for bleeding in patients with severe WMLs after intravenous thrombolysis to prevent bleeding as soon as possible.

METHODS: A large single-centre observational study conducted a retrospective analysis of intravenous thrombolysis in patients with severe WMLs from January 2018 to March 2021. According to whether symptomatic cerebral haemorrhage occurred, the patients were divided into two groups, and then statistical analysis was performed.

RESULTS: After a retrospective analysis of the data of nearly 1000 patients with intravenous thrombolysis and excluding invalid information, 146 patients were included, of which 23 (15.8%) patients had symptomatic cerebral haemorrhage. Univariate analysis showed that a history of hypertension (20% vs 4.9%, p=0.024), hyperlipidaemia (38.7% vs 9.6%, p<0.001), the National Institutes of Health Stroke Scale (NIHSS) score before thrombolysis (median 17 vs 6, p<0.001), low-density lipoprotein levels (median 2.98 vs 2.44, p=0.011), cholesterol levels (mean 4.74 vs 4.22, p=0.033), platelet count (median 161 vs 191, p=0.031), platelet distribution width (median 15.2 vs 12.1, p=0.001) and sodium ion levels (median 139.81 vs 138.67, p=0.043) were significantly associated with symptomatic cerebral haemorrhage. Further multivariate logistic regression analysis showed that hyperlipidaemia (OR=9.069; 95% CI 2.57 to 32.07; p=0.001) and the NIHSS score before thrombolysis (OR=1.33; 95% CI 1.16 to 1.52; p<0.001) were comprehensive risk factors for symptomatic cerebral haemorrhage.

CONCLUSION: Hyperlipidaemia and the NIHSS score before thrombolysis are independent risk factors for bleeding after intravenous thrombolysis in patients with severe WMLs. Delaying the onset of white matter and preventing risk factors for bleeding will help improve the prognosis of cerebral infarction and reduce mortality. These risk factors need to be further evaluated in future studies.
