Risk of dysphagia in a population of infants born preterm: characteristic risk factors in a tertiary NICU

Abstract Objective: To examine the prevalence and characteristics of dysphagia and suck-swallow-breath incoordination as phenotypes of oral feeding difficulties. Method: A cross-sectional study with secondary data collected consecutively over 2 years from October 2020 to October 2022 to measure the prevalence of swallowing and oral feeding difficulty in preterm infants using Flexible endoscopic evaluation of swallowing examination at the tertiary Integrated Dysphagia Clinic. Results: The prevalence of swallowing disorders was 25 % and the prevalence of suck-swallow-breath incoordination was 62.5 %. The significant risk factor that may show a possible correlation with oral feeding difficulty was mature post-menstrual age (p = 0.006) and longer length of stay (p = 0.004). The dominant percentage of upper airway abnormality and disorder were retropalatal collapse (40 %), laryngomalacia (42.5 %), paradoxical vocal cord movement (12.5 %), and gastroesophageal reflux disease (60 %). The dominant characteristic of oral motor examination and flexible endoscopic evaluation of swallowing examination was inadequate non-nutritive sucking (45 %), inadequate postural tone (35 %), and inadequate nutritive sucking (65 %). Conclusion: Dysphagia in preterm infants is mostly observed in those with mature post-menstrual age, longer length of stay, and the presence of gastroesophageal reflux disease with inadequate non-nutritive sucking and nutritive sucking abilities. Suck-swallow-breath incoordination is primarily observed in those with immature post-menstrual age, a higher prevalence of cardiopulmonary comorbidity, and a higher prevalence of upper airway pathologies (laryngomalacia, paradoxical vocal cord movement) with inadequate nutritive sucking ability.

The relationship between high ratios of CD4/FOXP3 and CD8/CD163 and the improved survivability of metastatic triple-negative breast cancer patients: a multicenter cohort study.

BACKGROUND: Triple-negative breast cancer (TNBC) has been documented as the most aggressive subtype of breast cancer. This study aimed to analyze antitumor and protumor immune activities, and their ratios as significant prognostic biomarkers in metastatic TNBC (mTNBC). METHODS: A multicenter cohort study was conducted among 103 de novo mTNBC patients. The expression of CD8 and CD163 was evaluated using immunohistochemistry staining, CD4 and FOXP3 using double-staining immunohistochemistry, and PD-L1 using immunohistochemistry and RT-PCR. RESULTS: Multivariate analysis revealed that high CD4/FOXP3 (HR 1.857; 95% CI 1.049-3.288; p = 0.034) and the CD8/CD163 ratio (HR 2.089; 95% CI 1.174-3.717; p = 0.012) yield significantly improved 1 year overall survival (OS). Kaplan-Meier analysis showed that high levels of CD4 (p = 0.023), CD8 (p = 0.043), CD4/FOXP3 (p = 0.016), CD8/FOXP3 (p = 0.005), CD8/CD163 (p = 0.005) ratios were significantly associated with higher rate of 1 year OS. Furthermore, 1 year OS was directly correlated with antitumor CD4 (R = 0.233; p = 0.018) and CD8 (R = 0.219; p = 0.026) and was indirectly correlated with protumor CD163 and FOXP3 through CD4/FOXP3 (R = 0.282; p = 0.006), CD4/CD163 (R = 0.239; p = 0.015), CD8/FOXP3 (R = 0.260; p = 0.008), and CD8/CD163 (R = 0.258; p = 0.009). CONCLUSION: This is the first study to demonstrate that high levels of CD4/FOXP3 and CD8/CD163 significantly improved the 1 year OS in de novo mTNBC patients. Thus, we recommend the application of these markers as prognosis determination and individual treatment decision.

Risk factors of prolonged diarrhea in children under 2 years old.

BACKGROUND: Prolonged diarrhea, defined as diarrhea lasting longer than 7 days, is known to negatively impact children's growth and development. However, studies of the risk factors of prolonged diarrhea remain limited. PURPOSE: This study aimed to analyze the risk factors for prolonged diarrhea in children under 2 years of age with acute diarrhea. METHODS: This 1-year nested case-control study was conducted at Fatmawati General Hospital in 2021-2022. Participants were selected using a consecutive sampling method from among children under 2 years of age with acute diarrhea within the previous 2-4 days. Children with diarrhea that lasted 7 days were considered positive for prolonged diarrhea, whereas those with acute diarrhea were considered negative. Children with comorbidities such as malnutrition were excluded. Clinical information including age, breastfeeding history, antibiotic exposure history, and nutritional status was recorded. Complete blood count, blood zinc levels, Rotavirus, adenovirus, and norovirus serology, alpha-1 antitrypsin (AAT) levels, and stool analysis were acquired as laboratory data. RESULTS: There were 62 subjects in the study and control groups. Overall, the median age was 12 months (6-24 months); most patients were boys. A history of antibiotic use (odds ratio [OR], 15.860; 95% confidence interval [CI], 5.286-47.591; P<0.001), zinc deficiency (OR, 4.758; 95% CI, 1.711-13.229; P=0.003), and elevated fecal AAT levels (OR, 2.677; 95% CI, 1.046-6.850; P=0.040) were the main risk factors for prolonged diarrhea in children under 2 years of age with acute diarrhea. CONCLUSION: A history of antibiotic use, zinc deficiency, and elevated fecal AAT levels were the main risk factors for prolonged diarrhea in children under 2 years of age with acute diarrhea. Thorough testing and appropriate antibiotic use are required to prevent prolonged diarrhea in children under 2 years of age.

Diagnostic accuracy of diffusion weighted imaging compared to magnetic resonance spectroscopy in differentiation of benign and malignant breast lesions: A systematic review and meta-analysis.

OBJECTIVE: To compare the sensitivity and specificity of diffusion weighted imaging (DWI) and magnetic resonance spectroscopy (MRS) in the differentiation of benign and malignant breast lesions. METHODS: Scopus, PubMed, and other registries were searched up to April 2023. We included diagnostic studies with DWI and MRS as index tests and histopathologic examination as the reference standard for differentiating benign and malignant breast lesions in adult females. We excluded studies involving healthy women, only breast cancer patients, and non-comparative diagnostic accuracy studies on either index test. The sensitivity and specificity of DWI and MRS were investigated and pooled using random-effect bivariate meta-analysis. Risk of bias was assessed using QUADAS-2. Evidence quality was summarized using GRADE. RESULTS: Eight eligible studies involving 632 females and 687 breast lesions were identified. The pooled sensitivity and specificity of DWI were 92% (CI 85-96%) and 88% (CI 75-94%), respectively. The pooled sensitivity and specificity of MRS were 85% (CI 66-94%) and 85% (CI 77-91%), respectively. No significant difference was noted in the sensitivity (7%, CI -8-22%) and specificity (3%, CI -9-14%) between DWI and MRS. CONCLUSIONS: In low to moderate quality evidence, DWI and MRS show comparable sensitivity and specificity in differentiating benign and malignant breast lesions.

The association of apolipoprotein in the risk of ST-elevation myocardial infarction in patients with documented coronary artery disease.

Introduction: Cardiovascular disease (CVD) is the number one cause of death worldwide, in this case, acute coronary syndrome (ACS) or acute myocardial infarction (AMI) that developed from coronary artery disease (CAD). Several risk factors contribute to AMI. Non-modifiable risk factors are age, sex, race, and family history. Modifiable risk factors include dyslipidemia, hypertension, smoking, diabetes mellitus, as well as recent factors that are considered more specific such as homocysteine, lipoprotein a [Lp(a)], high sensitivity C- reactive protein (hs-CRP), and apolipoprotein. This study aimed to determine the role of apolipoprotein as a risk factor for STEMI. Methods: This study combines three epidemiological designs: a descriptive and cross-sectional correlative study with 62 STEMI patients at the National Cardiovascular Center Harapan Kita and a comparative study of 62 STEMI patients and 20 non-ACS CAD patients at the Universitas Indonesia Hospital. Results and conclusion: The descriptive study showed the level of apoB 80.71 ± 28.3, apoA1 104.93 ± 27.8, apoB/apoA1 ratio 0.78 ± 0.22, and Lp(a) 6.85 (1.0-48.1). ApoB moderately correlates with LDLc (p < 0.001; r = 0.571). ApoA1 weakly correlates with HDLc (p = 0.005; r = 0.379). In comparative study, there were significant differences between the STEMI and non-ACS CAD groups on apoA1 (104.93 ± 27.8 vs. 137.48 ± 26.46), apoB/apoA1 ratio (0.78 ± 0.22 vs. 0.59 ± 0.15), and hs-CRP (2.88 [0.4-215] vs. 0.73 [0.15-8.9]). Multivariate analysis showed that the most significant risk factors for STEMI in this study were hypertension for modifiable factors and apoA1 for apolipoprotein. The apoA1 and apoB/apoA1 ratio examination can be suggested for people who have experienced plaque formation and are at risk for myocardial infarction.

Effect of Roselle Flower Extract (Hibiscus sabdariffa Linn.) on Reducing Steatosis and Steatohepatitis in Vitamin B12 Deficiency Rat Model.

Background and Objectives: Non-alcoholic Fatty Liver Disease (NAFLD) can occur as a result of micronutrient deficiencies. Hibiscus sabdarifa, a plant used in traditional medicine, contains ingredients that can help prevent this process. This study looked at the potency of Hibiscus sabdariffa Ethanol Extract (HSE) to prevent homocysteine-induced liver damage in animals that were deficient in vitamin B12. Materials and Methods: A comparative study of the effects of roselle extract is presented in an experimental design. Thirty Sprague-Dawley rats were divided into six groups using randomization. To demonstrate the absence of liver damage in the experimental animals under normal conditions, a control group was fed a normal diet without HSE. For the induction of liver damage in the experimental animals, the vitamin B12-restricted group was administered a vitamin B12-restricted diet. To test the effect of HSE on liver damage, the treatment group was given HSE along with a vitamin B12-restricted diet. Each group was given two treatment periods of eight and sixteen weeks. These results were compared with the results of the parameter examination between the vitamin B12 restriction group, with and without HSE, using an ANOVA statistic. The data were analyzed with licensed SPSS 20.0 software. Results: HSE significantly increased the blood levels of vitamin B12 while lowering homocysteine levels. The administration of HSE reduced liver damage based on the activity of liver function enzymes in the plasma due to a limitation of vitamin B12. HSE decreased Sterol Regulatory Element-Binding Protein-1c (SREBP1c) and Nuclear Factor Kappa B (NFkB) protein expressions in the liver tissue, but did not decrease Glucose-Regulated Protein 78 (GRP78) protein expression. Significantly, the levels of Tumor Necrosis Factor alpha (TNF-a) and IL-6 in the liver tissue were lower, while the levels of IL-10 and Nuclear factor-erythroid-2 Related Factor 2 (NRF2) were higher with HSE administration. HSE produced a better histopathological profile of the Hematoxylin and Eosin (H&E)-Masson tricrome for inflammation, fat and fibrosis in the liver. Conclusions: In this study, HSE was found to slow the development of liver damage in experimental animals that were given a vitamin B12-deficient diet.

The Association of Immune Cell Infiltration with Metastasis Location in De Novo Metastatic Triple Negative Breast Cancer: A Multicenter Cross-Sectional Study in Indonesia.

BACKGROUND: Triple-negative breast cancer (TNBC) is an aggressive cancer subtype, with limited treatments and a high metastasis risk. The varying location of metastasis in TNBC patients often leads to in prognosis in breast cancer. Therefore, this study aimed to investigate the potential association between immune cells profiles in the tumor microenvironment and metastatic patterns. METHODS: We conducted a multicenter cross-sectional study in 2022 to examine formalin-fixed paraffin-embedded (FFPE) and medical record data from 2015 to 2020 in de novo metastatic TNBC patients. The medical records provided crucial information about the sites of metastasis. Immunohistochemistry (IHC) analysis was carried out on primary breast tumor tissues to evaluate the expressions of cluster of differentiation (CD)4 T-cells, CD8 T-cells, CD163, FOXP3 Tregs, and programmed death-ligand 1 (PD-L1), along with immune cells ratios showing antitumor-to-protumor activity (CD4/FOXP3, CD8/FOXP3, CD4/CD163, CD8/CD163). Metastatic locations were grouped into bone-only, visceral, lung, liver, and brain metastasis.  Results: A total of 120 metastatic TNBC patients were documented for their metastatic location and IHC report. The clinical and histopathological characteristics showed that the majority of the patients were within the 40-65 years old group, and 34.2% had standard body mass index (BMI). Furthermore, the majority (89.22%) of the patients showed No Special Type (NST), (56.7%) had histopathology grade III, high Ki-67 ≥20% (85.8%), and positive PD-L1 expression (30.8%), with visceral metastasis indicating the highest proportion of 75.8%. Patients with a high CD8/FOXP3 and CD4/FOXP3 ratio were significantly prone to have bone-only metastasis compared to visceral metastasis (p= 0.028 and p=0.024, respectively).  Conclusion: The ratio of antitumor to protumor T-lymphocytes had a significant relevance in the metastatic location patterns in TNBC.

Dynamic contrast-enhanced magnetic resonance imaging parameter changes as an early biomarker of tumor responses following radiation therapy in patients with spinal metastases: a systematic review.

PURPOSE: This systematic review aims to assess and summarize the clinical values of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) parameter changes as early biomarkers of tumor responses following radiation therapy (RT) in patients with spinal metastases. MATERIALS AND METHODS: A systematic search was conducted on five electronic databases: PubMed, Scopus, Science Direct, Cochrane, and Embase. Studies were included if they mentioned DCE-MRI parameter changes before and after RT in patients with spinal metastases with a correlation to tumor responses based on clinical and imaging criteria. The Quality Assessment of Diagnostic Accuracy Studies 2 was used to assess study quality. RESULTS: This systematic review included seven studies involving 107 patients. All seven studies evaluated the transfer constant (Ktrans), six studies evaluated the plasma volume fraction (Vp), three studies evaluated the extravascular extracellular space volume fraction, and two studies evaluated the rate constant. There were variations in the type of primary cancer, RT techniques used, post-treatment scan time, and median follow-up time. Despite the variations, however, the collected evidence generally suggested that significant differences could be detected in DCE-MRI parameters between before and after RT, which might reflect treatment success or failures in long-term follow-up. Responders showed higher reduction and lower values of Ktrans and Vp after RT. DCE-MRI parameters showed changes and detectable recurrences significantly earlier (up to 6 months) than conventional MRI with favorable diagnostic values. CONCLUSION: The results of this systematic review suggested that DCE-MRI parameter changes in patients with spinal metastases could be a promising tool for treatment-response assessment following RT. Lower values and higher reduction of Ktrans and Vp after treatment demonstrated good prediction of local control. Compared to conventional MRI, DCE-MRI showed more rapid changes and earlier prediction of treatment failure.

Mesh-Tissue Integration of Platelet-Rich Plasma-Decellularized Amnion Scaffold-Polypropylene Mesh Sandwiches Implanted in the Vesicovaginal Spaces of Hypoestrogenic Rabbit Models: Protocol for a Randomized Controlled Trial.

BACKGROUND: Mesh-augmented surgery with polypropylene meshes (PPMs) is often used in urogynecology and pelvic reconstructive surgery. However, the various complications that arise from its integration process have resulted in a decrease in the number of mesh-augmented surgeries performed worldwide. An approach to improving mesh-tissue integration is coating PPMs with anti-inflammatory and wound-healing molecules, such as platelet-rich plasma (PRP), which is a component of biotechnologies that are capable of accelerating wound healing. Estrogen is also known to have a beneficial effect on wound remodeling; therefore, a hypoestrogenic status may have negative implications for wound healing. The mechanism of how PRP plays a role in wound remodeling, especially among individuals in a hypoestrogenic state, has not been fully described until now. OBJECTIVE: Our aim is to investigate the impact of applying PRP to PPMs in hypoestrogenic rabbit models. METHODS: Our study will be a randomized controlled trial involving hypoestrogenic rabbit models. Samples were categorized into either the PRP group or the PPM group (1:1 ratio), with a minimum sample size of 16 in each arm, via simple random sampling. All samples were put into a hypoestrogenic state via bilateral oophorectomy. After confirming a decrease in estradiol level, the meshes were implanted in the vesicovaginal space. The samples were euthanized on the 14th, 28th, or 90th day of the surgery. The mesh-tissue integration process will be analyzed based on inflammatory parameters (inflammatory infiltrate, interleukin-17, and interleukin-1B expression); angiogenesis (CD31 expression); and collagen deposition, which will be assessed by using Masson trichrome staining. RESULTS: Our study is in the protocol development stage. A preliminary study regarding its feasibility, including the feasibility of the preparation of hypoestrogenic rabbit models, mesh implantation in the rabbits' vesicovaginal spaces, the PRP and amnion scaffold, started in February 2022. The results of our study are expected to be available by the end of 2022. CONCLUSIONS: Our randomized controlled trial is designed to provide high-quality evidence on the effect of applying a PRP-decellularized amnion scaffold to PPMs in the vesicovaginal spaces of hypoestrogenic rabbit models.

The Role of Pretherapeutic Diffusion-Weighted MR Imaging Derived Apparent Diffusion Coefficient in Predicting Clinical Outcomes in Immunocompetent Patients with Primary CNS Lymphoma: A Systematic Review and Meta-Analysis.

OBJECTIVE: This systematic review and meta-analysis aimed to confirm the role of Apparent Diffusion Coefficient (ADC) values in predicting the prognosis of PCNSL patients based on previous studies. METHODS: A systematic review with meta-analysis was conducted on related articles PubMed, Scopus, Sciencedirect, Cochrane, DOAJ, and Embase databases with last updated search on November 30, 2021. This systematic review and meta-analysis included a total of four studies. RESULT: All studies that examined the association between pretherapeutic ADC values and OS and PFS discovered that lower ADC values were associated with significantly shorter OS and PFS. The analysis revealed that patients with low ADC values had a higher risk of death than those with high ADC values, with a pooled HR of 0.24 (95% CI: 0.10-0.56; Z = 3.26; p = 0.001). A meta-analysis of five data from three studies examining the association between ADC values and PFS was also conducted using a fixed-effects model due to the low heterogeneity values (I2 = 4%; p = 0.38). The data analysis revealed that the pooled HR was 0.25 (95% confidence interval [CI]: 0.14-0.44, Z = 4.18; p 0.00001). CONCLUSION: Patients with low ADC values had significantly shorter overall survival and progression-free survival than those with high ADC values, so ADC values assessment prior to initial therapy administration can provide clinicians with valuable information about the prognosis of PCNSL.

Serious fungal disease incidence and prevalence in Indonesia.

BACKGROUND: Indonesia is a tropical country, warm and humid, with numerous environmental fungi. Data on fungal disease burden help policymakers and clinicians. OBJECTIVES: We have estimated the incidence and prevalence of serious fungal diseases. METHODS: We found all published and unpublished data and estimated the incidence and prevalence of fungal diseases based on populations at risk. HIV data were derived from UNAIDS (2017), pulmonary tuberculosis (PTB) data from 2013-2019, data on chronic pulmonary aspergillosis (CPA) were used to estimate CPA prevalence and likely deaths, COPD data from Hammond (2020), lung cancer incidence was from Globocan 2018, and fungal rhinosinusitis was estimated using community data from India. RESULTS: Overall ~7.7 million Indonesians (2.89%) have a serious fungal infection each year. The annual incidence of cryptococcosis in AIDS was 7,540. Pneumocystis pneumonia incidence was estimated at 15,400 in HIV and an equal number in non-HIV patients. An estimated 1% and 0.2% of new AIDS patients have disseminated histoplasmosis or Talaromyces marneffei infection. The incidence of candidaemia is 26,710. The annual incidence of invasive aspergillosis was estimated at 49,500 and the prevalence of CPA is at 378,700 cases. Allergic bronchopulmonary aspergillosis prevalence in adults is estimated at 336,200, severe asthma with fungal sensitisation at 443,800, and fungal rhinosinusitis at 294,000. Recurrent vulvovaginal candidiasis is estimated at 5 million/year (15-50 years old). The incidence of fungal keratitis around 40,050. Tinea capitis prevalence in schoolchildren about 729,000. CONCLUSIONS: Indonesia has a high burden of fungal infections.

Minimal apparent diffusion coefficient value of the solid component to differentiate borderline and malignant ovarian epithelial tumours: a preliminary report.

PURPOSE: Ovarian tumours are the second most common cause of death from gynaecological cancer. There are three types of ovarian cancer based on histopathological examination: benign, borderline, and malignant. However, it is difficult to distinguish the borderline and malignant tumours. Several studies used the apparent diffusion coefficient value to distinguish the ovarian tumour types, with various results. This preliminary report focused more on the use of the minimal ADC (mADC) value on the solid component, to differentiate borderline and malignant ovarian tumours. MATERIAL AND METHODS: In 21 cases of borderline ovarian tumours, of which 11 were regarded as malignant and 10 were regarded as borderline following histopathological examination, the mADC value was measured by two different radiologists by using free-hand technique. The intraclass correlation coefficient (ICC) was used to measure the reliability and agreement between the two radiologists. Receiver-operating characteristic (ROC) curves were then calculated to determine the optimum cut-off point. RESULTS: There were statistically significant (p = 0.001) of the mADC value between the borderline and malignant tumours. The intraclass correlation coefficient value showed excellent reliability and agreement between the examiners. The ROC curve showed the optimum cut-off point at 0.628 × 10-3 mm2/s (p = 0.001), which yielded 100% sensitivity and 80% specificity. CONCLUSIONS: The use of free-hand technique to measure the mADC value on the solid component can be valuable in differentiating borderline and malignant ovarian epithelial tumours. This result may assist clinicians in considering further treatment approaches.

Patterns of Care and Outcome Analysis of Nasopharyngeal Carcinoma: An Indonesian Single Institution Study.

BACKGROUND: Nasopharyngeal cancer is endemic to Southeast Asia. However, there is limited clinical evidence of nasopharyngeal cancer in Indonesia, which has the largest population in Southeast Asia. METHODS: Patterns of care and treatment outcomes in 428 patients with newly-diagnosed and pathologically-confirmed nasopharyngeal cancer were retrospectively analyzed. RESULTS: Concurrent chemo-radiotherapy (CCRT) was the first-line treatment for stages I-IVB diseases. The 2-year overall survival (OS) of all patients were 100.0%, 100.0%, 93.8%, 86.2%, 82.9%, and 62.4% for stages I, II, III, IVA, IVB, and IVC, respectively. The 2-year OS of CCRT-treated patients were 100.0%, 100.0%, 92.6%, 82.4%, and 78.3% for stages I, II, III, IVA, and IVB, respectively. CONCLUSION: The patterns of care and treatment outcomes were potentially consistent with world standards, needing future validation. This is the largest study of newly diagnosed nasopharyngeal cancer in Indonesia, a huge disease burden, providing an important basis for the clinical management of this disease.

The Role of Serum Expression Levels of Microrna-21 on Bone Mineral Density in Hypostrogenic Postmenopausal Women with Osteoporosis: Study on Level of RANKL, OPG, TGFß-1, Sclerostin, RANKL/OPG Ratio, and Physical Activity.

BACKGROUND: MiR-21 is known to play a role in osteoclast proliferation and differentiation, but the role of serum miR-21 expression in osteoporosis remains unclear. Previous research found that serum miR-21 expression was positively correlated with bone mineral density in postmenopausal osteoporosis patients, but other factors involved in postmenopausal osteoporosis still unknown. This study aimed to determine the role of serum miR-21 expression, concentration of RANKL, OPG, TGF-ß1, sclerostin and serum calcium, RANKL/OPG ratio, and physical activity on bone mineral density of spine in hypoestrogenic postmenopausal women with osteoporosis (PMOP) compared with no osteoporosis (PMNOP), with point of interest on the expression of serum miR-21. METHODS: this study was conducted by comparative cross-sectional design. The subjects were divided into 2 groups of PMOP and PMNOP. We used an absolute quantification real-time PCR method to determine serum miR-21 expressions level. RESULTS: Median of serum miR-21 expression at the PMOP group was significantly higher compared to PMNOP group (p = 0.001). Serum miR-21 expression, RANKL, RANKL/OPG ratio, and physical activity were significantly correlated with BMD values in the PMOP group. Moderate physical activity was significantly negatively correlated with serum miR-21 expression. We also obtained a linear regression equation BMD = 1.373-0.085*Ln.miR-21-0.176*Log10.RANKL (R2 = 52.5%). CONCLUSION: serum miR-21 expression in PMOP was higher compared with PMNOP. Serum miR-21 expression proved to have a negative effect on spinal BMD values in hypoestrogenic postmenopausal women with osteoporosis of 8.5%. Obtained equation of BMD = 1.373-0.085*Ln.miR-21-0.176*Log10.RANKL can explain the value of spinal BMD by 52.5%.

A novel diagnosis scoring model to predict invasive pulmonary aspergillosis in the intensive care unit.

OBJECTIVES: To improve the quality of invasive pulmonary aspergillosis (IPA) management for intensive care unit (ICU) patients using a practical diagnostic scoring model. METHODS: This nested case-control study aimed to determine the incidence of IPA in 405 ICU patients, between July 2012 and June 2014, at 6 hospitals in Jakarta, Indonesia. Phenotypic identifications and galactomannan (GM) tests of sera and lung excreta were performed in mycology laboratory, Parasitology Department, Faculty of Medicine, Universitas Indonesia in Jakarta, Indonesia. RESULTS: The incidence of IPA in the ICUs was 7.7% (31 of 405 patients). A scoring model used for IPA diagnosis showed 4 variables as the most potential risk factors: lung excreta GM index (score 2), solid organ malignancy (score 2), pulmonary tuberculosis (score 2), and systemic corticosteroids (score 1). Patients were included in a high-risk group if their score was greater than 2, and in a low-risk group if their score was less than 2. CONCLUSION: This study provides a novel diagnosis scoring model to predict IPA in ICU patients. Using this model, a more rapid diagnosis and treatment of IPA may be possible. The application of the diagnosis scoring should be preceded by specified pre-requisites.

The Role of Cytotoxic T-lymphocyte-associated Protein 4 (CTLA-4) Gene, Thyroid Stimulating Hormone Receptor (TSHR) Gene and Regulatory T-cells as Risk Factors for Relapse in Patients with Graves Disease.

BACKGROUND: graves' disease (GD) is the most common condition of thyrotoxicosis. The management of GD is initiated with the administration of antithyroid drugs; however, it requires a long time to achieve remission. In reality more than 50% of patients who had remission may be at risk for relapse after the drug is stopped. This study aimed to evaluate the role of clinical factors such as smoking habit, degree of ophtalmopathy, degree of thyroid enlargement; genetic factors such as CTLA-4 gene on nucleotide 49 at codon 17 of exon 1, CTLA-4 gene of promotor -318, TSHR gene polymorphism rs2268458 of intron 1; and immunological factors such as regulatory T cells (Treg) and thyroid receptor antibody (TRAb); that affecting the relapse of patients with Graves' disease in Indonesia. METHODS: this was a case-control study, that compared 72 subjects who had relapse and 72 subjects without relapse at 12 months after cessation of antithyroid treatment, who met the inclusion criteria. Genetic polymorphism examination was performed using PCR-RFLP. The number of regulatory T cells was counted using flow cytometry analysis and ELISA was used to measure TRAb. The logistic regression was used since the dependent variables were categorical variables. RESULTS: the analysis of this study demonstrated that there was a correlation between relapse of disease and family factors (p=0.008), age at diagnosis (p=0.021), 2nd degree of Graves' ophthalmopathy (p=0.001), enlarged thyroid gland, which exceeded the lateral edge of the sternocleidomastoid muscles (p=0.040), duration of remission period (p=0.029), GG genotype of CTLA-4 gene on the nucleotide 49 at codon 17 of exon 1 (p=0.016), CC genotype of TSHR gene on the rs2268458 of intron 1 (p=0.003), the number of regulatory T cells (p=0.001) and TRAb levels (p=0.002). CONCLUSION: genetic polymorphisms of CTLA-4 gene on the nucleotide 49 at codon 17 of exon 1, TSHR gene SNP rs2268458 of intron 1, number of regulatory T cells and TRAb levels play a role as risk factors for relapse in patients with Graves' disease.
