Abstract

BACKGROUND: Surfactant replacement therapy is a recognized treatment for respiratory distress syndrome (RDS) in the newborns. Over the past 30 years, human and animal trials have been performed regarding administration of aerosolized surfactant to the injured lung, however the result has been unsatisfactory when compared with instilled surfactant delivery via endotracheal tube (ETT). This review aims to investigate the current issues, challenges and future recommendation of aerosolized surfactant therapy.CONTENT: Five randomized clinical trials in humans and 13 animal trials met the inclusion criteria and were reviewed. Most animal trials agree that this method of treatment is feasible. However, human trials presented conflicting results, and generally showed it to be ineffective. When compared with surfactant delivery via ETT, aerosolized surfactant is less effective in improving respiratory function.SUMMARY: The current data from human trials does not support the implementation of aerosolized surfactant therapy to treat newborns with RDS. Further research is necessary to improve nebulization, delivery, distribution and deposition in the lung, to investigate aerosolized surfactant delivery via ETT and to determine the appropriate dose.KEYWORDS: surfactant, aerosol, prematurity, respiratory distress syndrome

Abstract

BACKGROUND: Low-HDL cholesterol is a risk factor of CAD. Although levels of HDLC are within normal limit in some patients, they suffer CAD. These normal HDL-C levels might become pro-inflammatoric. This study is to measure the correlations between myeloperoxidase (MPO), serum amyloid-A (SAA) protein, and secretoryphospholipase-A2 (sPLA2) with inflammatory status of HDL-C.METHODS: This was a cross-sectional study recruited 49 subjects with high HDL-C (> 40 mg/dL) and 31 subjects with low HDL-C (< 40 mg/dL). HDL-C was determined into antiinflammatory and proinflammatory based on levels of Apo A-1 and hs-CRP. Concentrations of MPO, SAA and s-PLA2 were measured by ELISA method. Levels of Apo A-1 was determined by immunoturbidimetric method. Multiple logistic regression analysis was done using inflammatory status of HDL-C as dependent variables and levels of MPO, SAA, sPLA2, ages, total cholesterol and triglycerides as independent variables.RESULTS: Patient’s age was 43.4 + 8.3 year, HDL-C was 43.1 + 9.5 mg/dL, Apo A-1 was 128.3 + 21.5 mg/dL, hs-CRP was 1.92 + 3.0 mg/dL. Concentrations of MPO, SAA and sPLA2 successively were 63.2 + 16.9 ng/mL, 7015.6 + 5021.1 ng/mL and 1340.2 + 406.3 pg/mL. Multiple logistic regression analysis showed that SAA is an independent predictor of pro-inflammatory status of HDL-C in high HDL-C group with prevalence ratio of 11.74 (95% CI : 2.51 – 54.84; P = 0.002). In contrast, MPO and sPLA2 were not independent predictor with PR of 1.26 (95% CI : 0.30 – 5.23; P = 0.75) and of 0.94 (95% CI : 0.23 – 3.91; P = 0.93).CONCLUSIONS: SAA is an independent predictor of pro-inflammatory HDL-C even in subjects with high HDL-C.KEYWORDS: Atherosclerosis, Apo A-I, serum amyloid A protein, secretory phospholipase A2, myeloperoxidase

Abstract

BACKGROUND: Obesity has a central role in the metabolic syndrome, which raises the risk for atherosclerotic cardiovascular disease (ASVCD). Apo B-48 and Apo B-100 are the necessary structural proteins required for the assembly and secretion of chylomicron and VLDL which have role in atherogenesis. The key initiating process in atherogenesis is the subendothelial retention of apolipoprotein B-containing lipoproteins. Oxidation of LDL is a hallmark of atherosclerosis development. The aim of this study was to asses the association between Apo B-48 and Apo B-100 with Oxidized-LDL as marker of atherosclerosis risk in central obesity. We hope that the result of this study can help to make a new strategy for the prevention and treatment of vascular disease.RESULTS: There were 68 patients aged 39.6±7.3 years, Apo B-48 concentration was 7.47±5.36 μg/mL, Apo B-100 was 117.26±25.74 mg/dL, and ox-LDL was 137.05±18.88 U/L. This study showed a significant correlation between Apo B-100 and ox-LDL (r=0.608, p<0.05) and correlation between Apo B-48 and ox-LDL (r=0.171, p<0.05). The levels of Apo B-100 were significantly different between obese with Mets and obese without Mets individuals (p<0.05).CONCLUSIONS: This study suggested that Apo B-100 concentration increase in obese in Mets as compared with obese without Mets. Apo B-48 and Apo B-100 were correlated with Oxidized LDL, but correlation between Apo B-100 and ox-LDL more significant that Apo B-48and ox-LDL.KEYWORDS: obesity, atherogenesis, Apo B-48, Apo B-100, ox-LDL

Abstract

BACKGROUND: Central obesity is the accumulation of visceral (intra-abdominal) fat and is strongly known to be associated with insulin resistance and type 2 diabetes mellitus (T2DM). Obesity can cause adipocyte hypertrophy that results in dysregulation of adipokine expression. The abnormal function of adipocytes may play an important role in the development of a chronic low-grade proinflammatory state associated with obesity. Adiponectin, retinol binding protein (RBP)-4 and fetuin-A play a role in the pathophysiology of insulin resistance. Expression of fetuin-A is increased due to fat accumulation in the liver. Elevated concentration of fetuin-A in the circulation can impair insulin signaling in muscle and liver as well as suppress adiponectin secretion, although its molecular mechanism is still unclear. The aim of this study was to identify the relationship of fetuin-A, adiponectin, RBP-4 and hsCRP with insulin resistance in obese non diabetic men.METHODS: This was an observational study with a cross-sectional design. The study subjects were 64 men with non diabetic abdominal obesity, characterized by waist circumference of 98.47 ± 5.88 cm and fasting blood glucose of 85.75±8.36 mg/dL.RESULTS: This study showed that fetuin-A was positively correlated with HOMA-IR in obese non diabetic men with insulin resistance (r = 0.128; p = 0.570), although not significant. Fetuin-A was found to be correlated with adiponectin, RBP-4 and hsCRP (r=0.150; p=0.233; r=0.050; p=0.711; r=-0.04; p=0.445), although not significant.CONCLUSIONS: The concentration of fetuin-A showed a tendency to be positively correlated with HOMA-IR and with RBP-4 in obese non diabetic men, although statistically not significant. The concentration of fetuin-A showed a tendency to be negatively correlated with adiponectin and hsCRP although statistically not significant. There was no interrelationship between fetuin-A, adiponectin, RBP-4, hsCRP and HOMA-IR. Elevated concentrations of fetuin-A were noted in obese subjects, which in turn might impair insulin signaling. This finding might suggest that fetuin-A may represent a new target for the prevention of insulin resistance. Further studies might be needed on obese population with fatty liver.KEYWORDS: fetuin-A, adiponectin, RBP-4, hsCRP, insulin resistance

Abstract

BACKGROUND: Obesity is associated with insulin resistance, hypertension, and cardiovascular disease, but the mechanisms underlying these associations are incompletely understood. Microvascular dysfunction may play an important role in the pathogenesis of both insulin resistance and hypertension in obesity.CONTENT: Perivascular adipose tissue (PVAT) is a local deposit of adipose tissue surrounding the vasculature. PVAT is present throughout the body and has been shown to have a local effect on blood vessels. The influence of PVAT on the vasculature changes with increasing adiposity. PVAT similarly to other fat depots, is metabolically active, secreting a wide array of bioactive substances, termed ‘adipokines’. Adipokines include cytokines, chemokines and hormones that can act in a paracrine, autocrine or endocrine fashion. Many of the proinflammatory adipokines upregulated in obesity are known to influence vascular function, including endothelial function, oxidative stress, vascular stiffness and smooth muscle migration. Adipokines also stimulate immune cell migration into the vascular wall, potentially contributing to the inflammation found in atherosclerosis. Finally, adipokines modulate the effect of insulin on the vasculature, thereby decreasing insulin-mediated muscle glucose uptake. This leads to alterations in nitric oxide signaling, insulin resistance and potentially atherogenesis.SUMMARY: PVAT surrounds blood vessels. PVAT and the adventitial layer of blood vessels are in direct contact with each other. Healthy PVAT secretes adipokines and regulates vascular function. Obesity is associated with changes in adipokine secretion and the resultant inflammation of PVAT. The dysregulation of adipokines changes the effect of PVAT on the vasculature. Changes in perivascular adipokines secretion in obesity appear to contribute to the development of obesity-mediated vascular disease.KEYWORDS: obesity, perivascular adipose tissue, PVAT, cardiometabolic disease, adipokine

Abstract

BACKGROUND: Cancer is a disease of genomic instability, evasion of immune cells, and adaptation of the tumor cells to the changing environment. Genetic heterogeneity caused by tumors and tumor microenvironmental factors forms the basis of aggressive behavior of some cancer cell populations.CONTENT: Cancers arise in self-renewing cell populations and that the resulting cancers, like their normal organ counterparts, are composed of hierarchically organized cell populations. Self – renewing “cancer stem cells” (CSC) maintain tumor growth and generate the diverse populations constituting the tumor bulk. CSCs in multiple tumor types have been demonstrated to be relatively resistant to radiation and chemotherapy. The clinical relevance of these studies has been supported by neoadjuvant breast cancer trials that demonstrated increases in the proportions of CSCs after therapy. The CSC hypothesis has tremendously important clinical implications.SUMMARY: In summary, a large and accumulating body of evidence supports the CSC hypothesis, which has important implications for cancer prevention and therapy. The ultimate test of this hypothesis will require clinical trials demonstrating that targeting of these pathways reduces cancer incidence and improves outcomes for patients with cancer.KEYWORDS: Somatic mutation, tumor heterogeneity, metastasis, epithelial-mesenchymal transition, CSC niche

Abstract

BACKGROUND: Age-related muscle loss leads to lack of muscle strength, resulting in reduced posture and mobility and an increased risk of falls, all of which contribute to a decrease in quality of life. Skeletal muscle regeneration is a complex process, which is not yet completely understood.CONTENT: Skeletal muscle undergoes a progressive age-related loss in mass and function. Preservation of muscle mass depends in part on satellite cells, the resident stem cells of skeletal muscle. Reduced satellite cell function may contribute to the age-associated decrease in muscle mass. Recent studies have delineated that the aging process in organ stem cells is largely caused by age-specific changes in the differentiated niches, and that regenerative outcomes often depend on the age of the niche, rather than on stem cell age. It is likely that epigenetic states will be better define such key satellite cell features as prolonged quiescence and lineage fidelity. It is also likely that DNA and histone modifications will underlie many of the changes in aged satellite cells that account for age-related declines in functionality and rejuvenation through exposure to the systemic environment.SUMMARY: Skeletal muscle aging results in a gradual loss of skeletal muscle mass, skeletal muscle function and regenerative capacity, which can lead to sarcopenia and increased mortality. Although the mechanisms underlying sarcopenia remain unclear, the skeletal muscle stem cell, or satellite cell, is required for muscle regeneration. Decreased muscle stem cell function in aging has long been shown to depend on altered environmental cues, whereas the contribution of intrinsic mechanisms remained less clear. Signals in the aged niche were shown to cause permanent defects in the ability of satellite cells to return to quiescence, ultimately also impairing the maintenance of self-renewing satellite cells. Therefore, only anti-aging strategies taking both factors, the stem cell niche and the stem cells per se, into consideration may ultimately be successful.KEYWORDS: satellite cell, muscle, aging, niche, regenerations

Abstract

BACKGROUND: Biogenesis of HDL involves factors that regulate the synthesis, intravascular remodeling, and catabolism of HDL. Disturbance of these factors can lead to low concentration of HDL-C. Metabolic syndrome (MetS) is characterized by low concentration of high-density lipoprotein cholesterol (HDL-C). In MetS occur several pathological conditions including oxidative stress and impaired fibrinolysis, which contribute to the risk of atherosclerosis process. The correlation between oxidative stress and impaired fibrinolysis with HDL biogenesis dysfunction and its correlation with low concentration of HDL-C has not been well understood and therefore needs to be further investigated.METHODS: This study was an observational study with crosssectional design, involving 163 adult men, aged 25-60 years with metabolic syndrome. Concentration of apoA-1, prebeta-1 HDL, CETP, F2-isoprostan, PAI-1, and HDL-C were measured. The apo A1/HDL ratio indicated HDL maturation, whereas the CETP/HDL-C and CETP/TG ratios indicated HDL catabolism.RESULTS: The study showed that there were a positive correlation between PAI-1 with apoA1/HDL-C ratios (r=0.226, p=0.005) and a negative correlation with the CETP/TG ratios (r=-0.215, p=0.007), whereas F2-isoprostan did not have correlation with HDL biogenesis factors.CONCLUSIONS: We concluded that there was correlation between impaired fibrinolysis with decreased HDL maturation and there was increased HDL catabolism leading to low HDL-C concentration in men with metabolic syndrome.KEYWORDS: F2-isoprostan, PAI-1, apoA-1, prebeta-1 HDL, CETP, metabolic syndrome

Abstract

BACKGROUND: The prevalence of obesity and related disorders such as metabolic syndrome and diabetes has vastly increased throughout the world. Recent insights have generated an entirely new perspective suggesting that our microbiota might be involved in the development of these disorders. This represents an area of scientific need, opportunity and challenge. The insights gleaned should help to address several pressing global health problems.CONTENT: Our bowels have two major roles: the digestion and absorption of nutrients and the maintenance of a barrier against the external environment. They fulfill these functions in the context of, and with the help from, tens of trillions of resident microbes, known as the gut microbiota. Studies have demonstrated that obesity and metabolic syndrome may be associated with profound microbiotal changes, and the induction of a metabolic syndrome phenotype through fecal transplants corroborates the important role of the microbiota in this disease. Dietary composition and caloric intake appear to swiftly regulate intestinal microbial composition and function.SUMMARY: The interaction of the intestinal microbial world with its host, and its mutual regulation, will become one of the important topics of biomedical research and will provide us with further insights at the interface of microbiota, metabolism, metabolic syndrome, and obesity. A better understanding of the interaction between certain diets and the human gut microbiome should help to develop new guidelines for feeding humans at various time points in their life, help to improve global human health, and establish ways to prevent or treat various food-related diseases.KEYWORDS: gut microbiota, obesity, metabolic syndrome, type 2 diabetes

Abstract

BACKGROUND: Conventional autopsy in Indonesia is not well accepted as it is contrary to religion and culture. New radiological imaging method such as multislice computed tomography (MSCT) scan has potential to be a diagnostic tool in forensic pathology. The purpose of this study is to determine the ability of MSCT scan in finding abnormalities in close blunt head injury compared with autopsy.METHODS: This study used descriptive qualitative method. Postmortem cases in Department of Forensic Medicine and Radiology of Dr. Cipto Mangunkusumo Hospital were selected based on inclusion criteria. Then MSCT scan and autopsy were conducted. MSCT scan and autopsy results were compared and analyzed.RESULTS: There were 491 postmortem cases of blunt head injury. However, only 10 cases fulfilled inclusion criteria. Subarachnoid haemorrhages were identified 100% with MSCT scan and 80% with autopsy. Cerebral oedemas were identified 100% either with MSCT scan and autopsy. Subdural haemorrhages were identified 100% with MSCT scan, while 50% with autopsy. Multiple fractures were identified 80% with MSCT scan, while 40% with auto.CONCLUSION: MSCT scan showed a sensitive detection in finding abnormalities in close blunt head injury. Therefore it could be as an alternative choice of examination in close blunt head injury cases.KEYWORDS: multislice computed tomography scan, postmortem, blunt head injury, autopsy
