    The goal of this study was to compare heart function and arrhythmia in clinically asymptomatic patients with beta thalassemia intermedia and beta thalassemia major. In this cross-sectional study, 60 patients with beta thalassemia major and 60 patients with beta thalassemia intermedia who had clinically no symptoms of arrhythmia and clinically normal heart function were evaluated using 24-hour ambulatory electrocardiogram monitoring and echocardiography. For data analysis SPSS ver.20 software was used. A P-value of less than 0.05 was considered statistically significant. The mean age of the beta thalassemia intermedia patients was 24.18 ± 7.9 years and the mean age in beta thalassemia major was 24.38 ± 7.7 years (P>0.05). Premature atrial contractions (PACs) were observed in 14 (23.3%) patients with beta thalassemia intermedia and in 22 (36.6%) beta thalassemia major patients. Premature ventricular contractions (PVCs) were detected in 8 (13.3%) patients in the beta thalassemia intermediate group and 16 (26.6) patients in the beta thalassemia major group, respectively. The left ventricular diastolic dimension, end-diastolic volume, and stroke volume were significantly higher in beta thalassemia intermedia group (Pintermedia group. Both atrial and ventricular arrhythmias were more common in the beta thalassemia major group. Higher end-diastolic volume and stroke volume were detected in the beta thalassemia intermedia group. Pulmonary acceleration time was lower in the beta thalassemia intermedia group, which can be an indicator of higher pulmonary pressure.

    Objective: To describe and quantify the functional change of the lung in patients with beta-thalassemia major (TM) and determine the correlation between pulmonary function test (PFT) results with hemoglobin, ferritin and age changes. Methodology: Pulmonary function tests were performed on 60 transfusion-dependent patients with TM, ranging in age from 10 to 45 years. Percent-predicted values for forced expiratory volume in one second (FEV1), and forced expiratory flows (FEF) 25-75% were significantly reduced, whereas forced expiratory vital capacity (FVC) and FEV1/FVC were closed to normal limits, indicating a restrictive disease. All factors including; FVC, FEV1, and FEV1/FVC, FEF 25-75% were negatively correlated with age and ferritin levels. In contrast, all factors including; FVC, FEV1, and FEV1/FVC, FEF 25-75% were positively correlated with hemoglobin (Hb). We performed linear regression analysis to study the simultaneous influence of the presence of age, ferritin, and Hb on obstructive PFT indexes. Results: Pulmonary function test results were normal in only 32 (53.3%) of 60 patients and the rest 28 cases (46.7%) showed abnormal pulmonary function. FEV1 and FEF 25% - 75% have significant negative correlation with age (r = - 0.64 p(r) = 0.003 and r = - 0.58 p(r) = 0.02 respectively), also have significant positive correlation with Hb (r = 0.31 p(r) = 0.015 and r = 0.33 p(r) = 0.01 respectively), and only FEF 25% - 75% has significant negative correlation with ferritin (r -0.26 p(r) = 0.04). Conclusion: The present study has shown that restrictive disease and reduced lung diffusing capacity are the predominant abnormalities of pulmonary function patients with TM. The low hemoglobin concentration and a fall in the diffusing capacity of the alveola - capillary membrane, together with the dependence of the reduced pulmonary diffusing capacity on age and serum ferritin levels, as well as of the entity of restrictive disease on age, suggests that pulmonary

    Due to the tropism of human parvovirus B19 to erythroid progenitor cells, infection in patients with an underlying hemolytic disorder such as beta-thalassemia major leads to suppression of erythrocyte formation, referred to as transient aplasia crisis (TAC), which may be life-threatening. We investigated the prevalence of parvovirus B19 among patients with beta thalassemia major attending the Zafar Adult Thalassemia Clinic in Tehran, Iran. This cross-sectional study was performed to determine the presence of parvovirus B19 DNA in blood samples and parvovirus B19 genotypes in plasma samples of patients with thalassemia major. The population consisted of 150 patients with beta-thalassemia major who attended the Zafar clinic in Tehran. Specimens were studied using a real-time polymerase chain reaction assay. The prevalence of parvovirus B19 in our study population was 4%. Of 150 patients with thalassemia, six (4%) were positive for B19 DNA. There was no significant correlation between blood transfusion frequency and B19 DNA positivity. Finally, phylogenetic analysis of human parvovirus B19 revealed genotype I in these six patients. In this study, acute B19 infections were detected in patients with beta thalassemia major. Screening of such high-risk groups can considerably reduce the incidence and prevalence of B19 infection; thus, screening is required for epidemiologic surveillance and disease-prevention measures.

    Conclusion: Parvovirus B19 infection is detected in high rates among children with beta thalassemia major. Measures to avoid iatrogenic and nosocomial transmission have to be implemented including screening of donated blood for B19 especially blood given to patients with hematological disorders. Also data from this study support the need for introduction of an approved B19 vaccine that primarily protects children with thalassemia major against that infection.

    Objective to assess the neutrophil function in thalassemia major (TM)patients and compare it with the control group and to recognize its relevantfactors. This was a retrospective cohort study, which was carried out fromOctober 2007 to February 2008 in the Thalassemia research Center in Boo AliSina Hospital in Sari, Mazandaran, North of Iran. The study populationconsisted of TM patients in Boo Ali Sina Teaching Hospital. The method ofsampling in the case group was systematic and it was target based in thecontrol group. The sample size determined was based on previous studies.Thalassemia major was diagnosed based on hemoglobin electrophoresis (casegroup). The control group was their brothers and sisters, who had +-5 yearsof age difference and were of the same gender as the patients. Datacollection was based on interview, investigating demographic characteristicsand also obtaining medical information from medical records of the patients.The neutrophil function was by performing nitroblue tetrazolium (NBT)reduction test. The test was carried out on both groups and the data wereanalyzed by software using SPSS version 13.0. In this study, 39 patients and39 healthy controls were compared. The average age of the patients was21.6+-5.3 years and it was 22.4+-5.1 years in healthy controls (p=0.7). Therewas a significant correlation between the test's results and the patients age(p=0.008). The rate of impaired NBT results in the patients was 36%, while itwas 10% in controls, which were significantly different. The neutrophilactivity based on NBT test was 89.9+-11.6% in the case group and 93.7+-2.51%in the control group (p=0.025). This study indicates that neutrophil activityin thalassemia patients was significantly lower, compared to the normalcontrol group, especially in young patients. Based on the results, evaluationof neutrophil function and pyogenic infections in TM patients seemsnecessary. (author)

    To determine the frequency of hepatitis B and C virus infection among children with beta thalassemia major registered at Military Hospital Rawalpindi. Children attending Thalassemia Centre Military Hospital Rawalpindi for regular blood transfusion were registered. They belonged to different ethnic groups and came from different parts of the country. Their demographic data was recorded, detailed history taken and physical examination was carried out. Their serum samples were tested for hepatitis B surface antigen and anti HCV antibody assay with third generation commercial ELISA method. During the study; 141 patients of beta thalassemia major were screened. Out of them 50 patients (35.5% ,95% confidence interval 27.8-43.5)w ere found hepatitis C virus antibody positive and 1 patient (0.7 %) hepatitis B surface antigen positive. One patient (0.7%) had both hepatitis B and C virus infection. Mean age of hepatitis C infected patients was 10.4+3.85y ears (range 2-16 years). Mean age of uninfected patients was 6.1 + 3.59 years. (p value 0.000) In addition, the results indicate that higher prevalence of anti-HCV was significantly associated with longer duration of transfusion (p value <0.003). In spite of the fact that screened blood is used for transfusions, still a large number of patients have been found infected with hepatitis C. Therefore more accurate techniques are required for screening of blood to prevent transfusion associated transmission. (author)

    Background: Hypoparathyroidism is one of the most important endocrine complications of thalassemia major. This study was conducted to evaluate the prevalence of intracerebral calcifications in patients with thalassemia with and without hypoparathyroidism. Methods: 47 beta-thalassemia patients with hypoparathyroidism underwent a brain CT scan to investigate the presence and extent of intracerebral calcification. 30 age- and sex-matched beta-thalassemic patients with normal parathyroid function who had undergone brain CT for headache, or some other minor neurologic problems were also enrolled in the study serving as controls. The amount of intracerebral calcification, hematologic parameters, and some clinical findings were compared between both groups. Results: Intracerebral calcification was present in 54.2% of beta-thalassemia patients with hypoparathyroidism. The most frequent sites of calcification were basal ganglia, and frontoparietal areas of the brain. Thalami, internal capsule, cerebellum and posterior fossa were other less frequently calcified regions of the brain. In contrast, there was no evidence of intracerebral calcifications in the 30 thalassemic patients with normal parathyroid function. There was not a statistically significant difference between serum ferritin concentrations in thalassemia patient with hypoparathyroidism and those with normal parathyroid function (2781 vs. 2178, P > 0.05). Conclusion: Intracranial calcification is a common finding in thalassemia patients with hypoparathyroidism, it can be extensive and involves most regions of the brain.

    To evaluate bone metabolism in patients with beta-thalassemia major and to determine the factors associated with the development of osteoporosis. We studied 25 patients with thalassemia major with a mean age of 18.4 years (rang 5-31), age and gender matched 24 healthy controls who were attending the outpatient physical medicine and rehabilitation clinic of Akdeniz University Hospital between January 2004 and March 2004 in Turkey. Bone mineral density (BMD) of lumbar spine (L-1-L4) and proximal femur were determined using dual x-ray absorptiometry (DXA). Venous blood samples were obtained for determination of blood cell count and markers of bone formation and resorption. The BMD values, both at lumbar and femoral neck levels were significantly lower in patients compared to controls. Serum N-telopeptide level was slightly higher, whereas osteocalcin was slightly lower in patients, however, the values were not statistically significant. Plasma levels of insulin like growth factor-1 (IGF-I) and insulin like growth factor for binding protein-3 (IGFBP-3) were significantly lower in patients. Also, serum levels of estradiol and progesterone in females, luteinizing, hormone and follicle-stimulating hormone in both genders were significantly lower in patients. Serum levels of free testosterone and total testosterone were lower in patients, but not statistically significant. Patients also had significantly higher serum phosphorous levels and lower serum calcitonin levels compared to controls. The BMD is decreased in thalassemic patients. Growth retardation, growth hormone/IGF-I/IGFP-3 axis dysfunction, gonadal dysfunction and hypothalomo-pituitary-gonadal axis dysfunction may be responsible for the development of osteoporosis in the patients with beta-thalassemia major.

    We evaluated therapy complications in 19 beta-thalassemia major patients (mean age from 3 years/5 months and 1 years/6 months) who were followed at II Pediatric Department-University of Bari. 3 out of 19 patients underwent allogenic BMT from matched related donor; 2 out of 19 underwent splenectomy. All of them were receiving hypertransfusion therapy and continuous chelation with DFO. In all patients we performed physical examination, laboratory assays, cardiac and endocrinologic function tests, serum HBV-HCV-HIV antibodies, otoscopy and audiometric test, fundus oculi, skeletal x-ray. 1 out of 19 patients, who was under 15, had a slight dilatation of left ventricle and arythmia. All patients were HBsAb positive. 4/19 patients were HCV Ab positive (ELISA test) with an increase in ALT-AST serum levels since at least 6 months. In 3 of them we assessed RIBA test, always positive. 3 of them underwent liver biopsy (1 iron overload 2 chronic active hepatitis). All patients were HIV Ab negative. 4/15 patients revealed low GH levels after Arginina test. 13 pre-pubescent patients had normal results with GNRH test but lower results after FSH test. 1 pubescent patient had gonadotropic hypophyseal deficit. 4 patients had subclinic hypothiroidism. We couldn't find any sequelas in bone-eyes-ears. Hypertransfusion therapy, chelation, profilaxis of infections improved length and quality of life in thalassemic patients. Hypogonadotropic hypogonadism remains a serious sequela and we think it needs to be treated.

    The objective was to determine the survival of beta-thalassemia major patients with transfusion, and its related factors in Southeast of Iran. This cross-sectional study was performed in Zahedan, Iran in 2007. The sample included patients who were referred from all over the Zahedan Thalassemia Center from 1998 to 2006. The data were collected using the patient's records, which were recorded by the staff during transfusion. The data included demographic and medical information blood group, blood RH, the kind of transfused blood [KTB], annual number of transfusions [ANOT], accompanied disease [AD], Hemoglobin [Hb] and ferritin level. For data analysis, the Kaplan-Meyer method, and Long Rank test together with Cox Regression were used. Forty-six of 578 patients died and 99% survived for the first year. The ages survival proportions were 5 (97.9%), 10 (97%), 15 (92.1%), and 20 (81.2%) years. The survival time showed significant relationships with the ANOT p=0.0053, KTB p=0.003, Hb=0.002 and ferritin level p=0.0087, and AD p=0.00. Using regular transfusion, paying attention to screening of transfused blood, increasing the families knowledge on the disease to prevent the bearing of thalassemia fetus, are recommended; finally, the detection and treating of the AD, are of great importance to extend the lifetime of the patients.

    Full Text Available Beta-thalassemia is one of the most prevalent autosomal disorders, which affect more than 400,000 newborn per year worldwide. In India, the carrier rate of beta-thalassemia varies from 3-17%. The overall rate of alloimmunization in thalassemia patients has been reported to be 5-30% in the world, which is mostly contributed by the alloimmunization to minor blood group antigen. Among Asians, the incidence of red cell alloimmunization is 22%. The recommended treatment for beta-thalassemia major is regular blood transfusion every 3 to 4 weeks. The development of anti-red cell antibodies (alloantibodies and/or autoantibodies can significantly complicate transfusion therapy. Alloantibodies are commonly associated with red cell hemolysis. Red cell autoantibodies appear less frequently, but they can result in clinical hemolysis called autoimmune hemolytic anemia (AIHA, and in difficulty in cross-matching blood. Patients with autoantibodies may have a higher transfusion rate and often require immunosuppressive drugs or alternative treatments including intravenous immunoglobulin (IVIg and rituximab (anti-CD20 monoclonal antibody.

    Full Text Available Objectives: Chelating agents remain the mainstay in reducing the iron burden and extending patient survival in homozygous beta-thalassemia but adverse and toxic effects may increase with the institution and long term use of this essential therapy. This study aimed to estimate the incidence of deferasirox (DFX side effects in patients with thalassemia major or intermedia.Methods: A retrospective study of 72 patients (mean age: 20.3±0.9 yrs; 36 male, 36 female with thalassemia major or intermedia treated at Sultan Qaboos University Hospital, Oman, was performed to assess the incidence of side effects related to deferasirox over a mean of 16.7 month follow-up period.Results: Six patients experienced rashes and 6 had gastro-intestinal upset. DFX was discontinued in 18 patients for the following reasons: persistent progressive rise(s in serum creatinine (7 patients; 40% mean serum creatinine rise from baseline, feeling unwell (2, severe diarrhea (1, pregnancy (1, death unrelated to chelator (2 and rise in serum transaminases (2. Three patients were reverted to desferoxamine and deferiprone combination therapy as DFX was no longer biochemically effective after 18 months of therapy. There was no correlation between baseline serum ferritin and serum creatinine or a rise in serum creatinine. Cardiac MRI T2* did not change with DFX therapy. However, there was an improvement in liver MRI T2* (p=0.013.Conclusion: Renal side effects related to deferasirox appear to be higher than those reported in published clinical trials. Further larger studies are required to confirm these findings.

    Mental health and health related quality of life is commonly affected in patients with chronic problems and their caregivers. In the present study, it was aimed to assess depression and anxiety in patients with beta thalassemia major (BTM) and in their caregivers; and to evaluate effects of these disorders on quality of life. The study was carried out in a district Hereditary Hemoglobinopathy Center and included 88 patients with BTM and 63 of their caregivers. All subjects were assessed using Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI) and Short Form-36 (SF-36) by a trained psychiatry resident via face-to-face interview. The BDI scores were 17 or above in 20.5% of the patients with BTM and 28.6% of their caregivers (P = 0.248). Of the patients with BTM, there were mild anxiety symptoms in 19.3%, while moderate and severe anxiety symptoms in 14.8% and 4.5%, respectively. Anxiety levels were similar between the patients with BTM and their caregivers (P = 0.878). It was found that BDI and BAI scores were negatively correlated to scores of physical health and mental health components of SF-36 in patients with BTM and their caregivers. In linear regression analysis, it was seen that depression affected physical and mental health of the patients with BTM and their caregivers regardless from anxiety. BTM leads an increase in the frequency of depression and anxiety in both patients and their caregivers, and affects negatively physical and mental components of quality of life.

    Full Text Available CONTEXT AND OBJECTIVE Patients with beta-thalassemia major (β-TM experience physical, psychological and social problems that lead to decreased quality of life (QoL. The aim here was to measure health-related QoL and its determinants among patients with β-TM, using the Short Form-36 (SF-36 questionnaire. DESIGN AND SETTING Cross-sectional study at the Hematology Research Center of Shiraz University of Medical Sciences, in southern Iran. METHODS One hundred and one patients with β-TM were randomly selected. After the participants' demographics and disease characteristics had been recorded, they were asked to fill out the SF-36 questionnaire. The correlations of clinical and demographic factors with the QoL score were evaluated. RESULTS There were 44 men and 57 women of mean age 19.52 ± 4.3 years (range 12-38. On two scales, pain (P = 0.041 and emotional role (P = 0.009, the women showed significantly lower scores than the men. Lower income, poor compliance with iron-chelating therapy and presence of comorbidities were significantly correlated with lower SF-36 scores. These factors were also found to be determinants of worse SF-36 scores in multivariate analysis. CONCLUSIONS We showed that the presence of disease complications, poor compliance with iron-chelating therapy and poor economic status were predictors of worse QoL among patients with β-TM. Prevention and proper management of disease-related complications, increased knowledge among patients regarding the importance of managing comorbidities and greater compliance with iron-chelating therapy, along with psychosocial and financial support, could help these patients to cope better with this chronic disease state.

    In transfusion-dependent {beta}-thalassemia major, increased iron deposition in the pituitary gland has a cytotoxic effect leading mainly to hypogonadotropic hypogonadism. Our purpose was to assess in these patients the height of the pituitary gland and to evaluate whether it represents a marker of pituitary gland function. In 29 patients with {beta}-thalassemia major and 35 age- and gender-matched controls the pituitary gland height was evaluated in a midline sagittal scan using a spin echo T1-weighted (500/20 TR/TE) sequence. In all patients, an extensive endocrine evaluation was performed, including measurements of spontaneous and stimulated levels of gonadotropins, thyroid hormones, growth hormone, insulin-like growth factor, and adrenal hormones. The pituitary gland height was lower in thalassemic patients with hypogonadotropic hypogonadism (n=15) (mean 3.48; SD 0.46) than in the age- and gender-matched controls (mean 6.29; SD 0.77), (P<0.001). No statistically significant difference was found between thalassemic patients without hormone dysfunction (n=14) (mean 5.34; SD 1.52) and age- and gender-matched controls (mean 5.91; SD 1.06). We conclude that in thalassemic patients the pituitary gland height is an additional marker of pituitary gland function and might be useful in clinical management. (orig.)

    Beta Thalassemia (βT) patients present a unique facial appearance and specific craniofacial, jaw and dental patterns. Although this anomaly often requires orthodontic management, βT patients have received scant attention in the orthodontic and dental literature over the past 50 years. The aim of this article is to review the characteristic craniofacial and dental manifestation pattern of βT patients and to emphasize their preferred orthodontic management protocol by presenting a βT orthodontic treated patient. A 10 year old patient presented with a complaint of severe esthetic and functional disorders due to her diagnosis of βT. We initiated orthodontic treatment including a combined orthopedic and functional treatment modality to improve facial appearance. Maxillary restraint and increased mandibular size during treatment along with an increase in the vertical dimension were achieved. The patient presented with Angle class I molar relationship, with reduction of the excessive overjet and deep overbite. Orthodontic treatment comprised of maxillary orthopedic treatment directed especially toward premaxilla with light forces, and mandibular modification by functional appliance along with fixed orthodontic treatment is recommended in βT patients.

    In this article magnetic measurements were made on human erythrocytes at different hemoglobin states (normal and reduced hemoglobin). Different blood samples: normal, beta thalassemia major, and sickle were studied. Beta thalassemia major and sickle samples were taken from patients receiving lifelong blood transfusion treatment. All samples examined exhibited diamagnetic behavior. Beta thalassemia major and sickle samples showed higher diamagnetic susceptibilities than that for the normal, which was attributed to the increase of membrane to hemoglobin volume ratio of the abnormal cells. Magnetic measurements showed that the erythrocytes in the reduced state showed less diamagnetic response in comparison with erythrocytes in the normal state. Analysis of the paramagnetic component of magnetization curves gave an effective magnetic moment of μeff=7.6 μB per reduced hemoglobin molecule. The same procedure was applied to sickle and beta thalassemia major samples and values for μeff were found to be comparable to that of the normal erythrocytes.

    Objective: To determine the status of thyroid functions in patients of Beta Thalassemia Major, reporting to OPD of Military Hospital, Rawalpindi. Study Design: Descriptive cross sectional study. Place and Duration of Study: Paediatric Outpatients Department of Military Hospital, Rawalpindi from 1st Jan to 30th Jun 2012. Material and Methods: After taking informed consent from the parents of all the children fulfilling the inclusion criteria, detailed history was taken and blood samples were drawn by strict aseptic means. Samples taken from these patients included complete blood and thyroid profile (serum thyroxine T4, triiodothyronine T3 and thyroid stimulating hormone TSH). These blood samples were labeled and sent to Armed Forces Institute of Pathology (AFIP), Rawalpindi for analysis by enzyme-linked immunosorbent assay (ELISA). Primary hypothyroidism was defined by TSH levels >4IU/ml. Statistical analysis was done at the end of study using SPSS version 10. Significance for association was calculated using student t-test. Results: Sixty patients fulfilled the inclusion criteria out of these sixty four patients lost the follow up while 56 patients completed the study. Out of 56 patients, 21 (37.5 percent) had biochemical evidence of hypothyroidism. Mean Ferritin level was 3924 +- 1247ng/ml in hypothyroid and 3136 +- 1387ng/ml in euthyroid patients indicating a significant difference in mean serum ferritin levels between hypothyroid patients and others. Conclusion: The study demonstrates hypothyroidism in a significant number of hyper transfused Beta- thalassemic patients, emphasizing the importance of monitoring thyroid functions in thalassemic patients, particularly in those receiving suboptimal chelation.

    Full Text Available Beta-thalassemia is a group of frequent genetic disorders resulting in the synthesis of little or no β-globin chains. Novel approaches are being developed to correct the resulting α/β-globin chain imbalance, in an effort to move beyond the palliative management of this disease and the complications of its treatment (e.g. life-long red blood cell transfusion, iron chelation, splenectomy, which impose high costs on healthcare systems. Three approaches are envisaged: fetal globin gene reactivation by pharmacological compounds injected into patients throughout their lives, allogeneic hematopoietic stem cell transplantation (HSCT, and gene therapy. HSCT is currently the only treatment shown to provide an effective, definitive cure for β-thalassemia. However, this procedure remains risky and histocompatible donors are identified for only a small fraction of patients. New pharmacological compounds are being tested, but none has yet made it into common clinical practice for the treatment of beta-thalassemia major. Gene therapy is in the experimental phase. It is emerging as a powerful approach without the immunological complications of HSCT, but with other possible drawbacks. Rapid progress is being made in this field, and long-term efficacy and safety studies are underway.

    Full Text Available To evaluate the prevalence of renal tubular dysfunction in children with β-thalassemia (β-T major, we studied the glomerular and tubular function in 140 children with β-T major and compared them to a healthy control group at our center from May 2007 to April 2008. Fresh first morning samples were collected from each patient and analyzed for sodium, potassium, calcium (Ca, protein, uric acid (UA, creatinine (Cr, urine osmolality and urinary N-acetyl-β-D-glucosaminidase (UNAG activity. Blood samples were also collected for complete blood count, blood urea nitrogen (BUN, fasting blood sugar, serum creatinine (SCr, electrolytes, and ferritin before transfusion. Among the study patients, 72 were males, and the mean age was 11.5 (ranging 7-16 years. SCr levels were all within normal limits and all of them had normal glomerular filtration rate (GFR. The mean UNAG was 17.8 IU/L in the study patients (normal 0.15-11.5 IU/L and 3.2 IU/L in the control group (P 0.21 (P = 0.006. Nine (6.4% thalassemic patients with a mean age of 12 years had proteinuria (Upr/UCr > 0.2. Sixty-nine (49.3% out of the 140 patients and 45 (65.2% of the patients having UNAG had uricosuria also (UUA/UCr > 0.26. Ten (7% patients had microscopic hematuria and 10 (7% patients with a mean age of 13.5 years had glucosuria or diabetes mellitus. We conclude that tubular dysfunction is a relative common complication of the β-T major; UNAG and its index are the best to detect renal tubular dysfunction in these patients. Currently, periodic measurement of UCa/UCr and UUA/UCr ratios as well as urinalysis are recommended.

    2013-06-01

    Full Text Available Background: Thalassemia is a hereditary hemoglobinopathy whose most common complication is cardiac involvement which ends up in these patients’ death. Since troponin is a sensitive and specific marker for the detection of microinfarct, we studied the relationship between troponin and ferritin serum levels for early diagnosis of cardiac involvement in these patients. Materials and Methods: This case-control study was performed on 80 patients, including 40 patients with major thalassemia and normal echocardiography and 40 healthy volunteers ranging from 6 months to 16 years old. All the children were examined and the eligible children who were not infected with known heart disease, iron deficiency anemia, kidney disease, diabetes, fever, and systemic diseases were enrolled into the study after obtaining written informed consents from their parents. At 8:00 A.M. before breakfast, 5cc blood was drawn from these children. After collecting the samples, ferritin and troponin serum levels were evaluated using ELISA and electro- kymonolonsense methods, respectively. The gathered data were analyzed through the SPSS statistical software (v. 20 and T-test. Besides, P value<0.05 was considered as statistically significant. Results: The study results revealed a significant difference between the two groups regarding the mean of the serum levels of troponin (P=0.045 and ferritin (P=0.001. In this study, no significant correlation was observed between serum troponin and ferritin levels and age and BMI in the two groups. Also, no significant relationship was found between serum troponin level and sex (P=0.264. Conclusions: In microinfarct, troponin increases independent of ferritin; therefore, it can be used for early detection of cardiac involvement in thalassemia patients to determine the sub-clinical effects.

    Full Text Available Background: Diabetes mellitus is a major complication of iron overload in patients with beta thalassemia major. Design: This is a descriptive study conducted in a Tertiary Care Teaching Hospital to analyze beta cell function and insulin resistance, and their relation to iron overload status in beta thalassemia major. Fasting glucose, two-hour post load glucose, fasting insulin, alanine amino transaminase (ALT, and ferritin were used as outcome measures. The homeostatic model assessment (HOMA model was used to calculate the beta cell function and insulin resistance index. Results: Of the 30 cases, 20% had impaired fasting glucose, 3.3% had impaired glucose tolerance, and none had diabetes. Fasting glucose was not significant between the cases and controls (P = 0.113. Fasting insulin (P = 0.001, ferritin (P = 0.001, and ALT (P = 0.001 levels were significantly high in the cases. Insulin resistance index was significantly higher in the cases (P = 0.001 as also the beta cell function (P = 0.001. With increase in age and the number of units transfused there is a decline in beta cell function, fasting insulin, and insulin resistance after attaining the maximum level. This suggests that initial insulin resistance is followed by insulin depletion due to loss of beta cell function, leading to diabetes mellitus. Conclusion: Impaired glucose tolerance (IGT and insulin resistance precede the onset of insulin-dependent diabetes and adequate chelation therapy is essential for delaying the onset or for prevention of diabetes.

    Beta thalassemia major is a rare hereditary blood disease in which impaired synthesis of beta globin chains causes severe anemia. Medical treatment consists of chronic blood transfusions and iron chelation. We describe two cases of adolescents with beta thalassemia major with unplanned pregnancies and late onset of prenatal care. One had worsening of anemia with increased transfusional requirement, fetal growth restriction, and placental senescence. The other was also diagnosed with hypothyroidism and low maternal weight, and was admitted twice during pregnancy due to dengue shock syndrome and influenza H1N1-associated respiratory infection. She also developed fetal growth restriction and underwent vaginal delivery at term complicated by uterine hypotonia. Both patients required blood transfusions after birth and chose medroxyprogesterone as a contraceptive method afterwards. This report highlights the importance of medical advice on contraceptive methods for these women and the role of a specialized prenatal follow-up in association with a hematologist.

    Thalassemia is a hereditary anemia resulting from defect in hemoglobinproduction. Beta thalassemia is due to impaired production. Beta thalassemiais due to impaired production of beta globin chains, leading to a relativeexcess of alpha globin chains. The term beta thalassemia minor is used todescribe heterozygotes, who carry one normal beta globin and one betathalassemic allele. The vast majority of these patients are asymptomatic.However, a variety of renal tubular abnormalities including hypercaliuria,hypomagnesemia with renal magnesium wasting, decreased tubular absorption ofphosphorous, hypouricemia with renal uric acid wasting, renal glycosuria andtubular proteinuria have been described even in patients with betathalassemia minor. We here in report a 24-year old patient who was found tohave thalassemia minor and nephrocalcinosis with evidence of renal tubulardysfunction. Investigations revealed normal renal function, hypercalciuria,reduced tubular reabsorption of phosphorous, hypomagnesemia and renalmagnesium wasting. Screening for aminoaciduria was found to be negative. Anacid loading test revealed normal urinary acidification. Ultrasonogram of theabdomen revealed nephrocalcinosis and splenomegaly. Detailed work up foranemia showed normal white cell and platelet count while peripheral smearshowed microcytic hypochromic anemia with few target cells. Hemoglobinelectrophoresis revealed hemoglobin A of 92%, hemoglobin A2 of 6.2% andhemoglobin F of 1.8% consistent with beta thalassemia minor. Her parentalscreening was normal. A diagnosis of beta thalassemia minor with renaltubular dysfunction was made and the patient was started on thiazidediuretics to reduce hypercalciuria and advised regular follow-up. (author)

    Full Text Available Objectives: Organ-specific hemosiderosis and iron overload complications are more serious and more frequent in some patients with beta thalassemia major (BTM compared with others. We investigated whether coinheritance of HFE H63D or C282Y gene mutations in patients with BTM contributes to the phenotypic variation of iron overload complications and assessed the correlation of cardiac and hepatic hemosiderosis with plasma ferritin levels. Methods: We studied 60 patients with BTM with a mean age of 17.5±9.1 years from the Northwest of Iran. HFE gene mutations were analyzed using the polymerase chain reaction-restriction fragment length polymorphism method. Cardiac and hepatic hemosiderosis was assessed using T2*magnetic resonance imaging (MRI. Ferritin levels were measured using the enzyme immunoassay method. Results: Ferritin levels showed a strong inverse correlation with hepatic T2*MRI values (r = -0.631, p = 0.001 but a poor correlation with cardiac T2*MRI values (r = -0.297, p = 0.044. The correlation between cardiac T2*MRI values and hepatic T2*MRI values was poor and insignificant (r = 0.287, p = 0.058. Genotype and allele distribution of HFE H63D and C282Y mutation did not differ significantly between patients with and without hepatic or cardiac hemosiderosis (p > 0.050. However, carriers of HFE 63D allele had significantly higher ferritin levels compared with non-carriers (1 903±993 vs. 992±683, p < 0.001. Conclusions: Cardiac T2*MRI values showed a poor correlation with hepatic T2*MRI values and ferritin levels. Accurate assessment of cardiac iron overload in patients with BTM can only be done using the T2*MRI technique. Additionally, HFE H63D is a significant determinant factor for elevated ferritin levels in BTM patients.

    Iron overload is a major problem in patients with beta-thalassemia major, and it has many structural and metabolic consequences. The aim of this study was evaluation of endocrine disturbances in patients with beta-thalassemia major who were older than 10 years of age. In this cross-sectional study, investigator collected demographic data and medical histories, as well as menstrual history in females, from the medical records of 56 patients with beta-thalassemia major. Patients were examined to determine their pubertal status and the standard deviation score for height for evaluation of short stature. For evaluation of glucose tolerance, a fasting blood glucose and oral glucose tolerance tests were performed. Evidence for diabetes mellitus was based on American Diabetes Association and World Health Organization criteria. Serum levels of calcium, phosphorous, thyroid-stimulating hormone, free thyroxin, luteinizing hormone and follicular-stimulating hormone and estradiol in girls and testosterone in boys were measured. The mean and standard deviation for age in the 56 patients (36 males and 20 females) was 15.62+-4.44 years. Diabetes mellitus was present in 5 patients (8.9%), impaired fasting glucose was found in 16 patients (28.6%) and an impaired glucose tolerance test was found in 4 patients (7.1%). Short stature (standard deviation score <-2) was seen in 25 (70%) boys and 14 (73%) girls. Impaired puberty was found in 40 patients (71%). Hypocalcaemia and primary overt hyperthyroidism were present in 23 (41%) and 9 patients (16%), respectively. Only eight patients (14.3%) had no endocrine abnormalities. Despite therapy with deferoxamine to treat iron overload, the risk of secondary endocrine dysfunction remained high. Hypogonadism was one of the most frequent endocrine complications. Impaired glucose tolerance, short stature, hypocalcemia, subclinical and overt hypothyroidism are also frequent. (author)

    Full Text Available Background There is evidence indicating impaired cardiomyocytic contractility, delayed electrical conduction and increased electrophysiological heterogeneities due to iron toxicity in beta-thalassemia major patients. In the present study, we compared the electrocardiographic and echocardiographic features of beta-thalassemia major patients with a healthy control group. Materials and Methods The average annual serum ferritin levels of fifty beta-thalassemia major patients were assessed. For each patient, corrected QT (QTc intervals and QTc dispersions (QTcd were calculated and V1S and V5R were measured. All subjects underwent two-dimensional M-mode echocardiography and Doppler study and were compared with 50 healthy subjects as a control group. Results QTc interval and dispersion were significantly higher in beta-thalassemia major patients (P= 0.001. The mean V5R (20.04 ± 4.34 vs. 17.14 ± 2.55 mm and V1S (10.24 ± 2.62 vs. 7.83 ± 0.38 mm showed considerably higher mean values in patients in comparison with control group.Peak mitral inflow velocity at early diastole and early to late ratio in the case- group was markedly higher(P

    Diagnostic x-ray spectrometry, a method based on x-ray fluorescence analysis, was used for noninvasive determination of iron and zinc in two distinct skin areas, representing predominantly dermal and epidermal tissues, in 56 patients with beta-thalassemia major and intermedia. The mean iron levels in the skin of patients with beta-thalassemia major and intermedia were elevated by greater than 200% and greater than 50%, respectively, compared with control values. The zinc levels of both skin areas examined were within the normal range. The data indicate that the rate and number of blood transfusions, which correlated well with serum ferritin levels (r . 0.8), are not the only factors that determine the amount of iron deposition in the skin (r less than 0.6). Other sources of iron intake contribute to the total iron load in the tissues, particularly in patients who are not given multiple transfusions. The noninvasive quantitation of skin levels may reflect the extent of iron deposition in major parenchymal organs. Repeated DXS examinations of the skin could monitor the clearance of iron from the tissues of patients with iron overload in the course of therapy with chelating agents

    The study aims at describing the MR features of pancreas in beta-thalassemia major, investigating the relations between MR findings and glucose disturbances and between hepatic and pancreatic siderosis. Signal intensity ratios of the pancreas and liver to right paraspinous muscle (P/M, L/M) were retrospectively assessed on abdominal MR imaging studies of 31 transfusion-dependent patients with beta-thalassemia major undergoing quantification of hepatic siderosis and 10 healthy controls, using T1- (120/4/90), intermediate in and out of phase - (120/2.7, 4/20), and T2*-(120/15/20) weighted GRE sequences. Using the signal drop of the liver and pancreas on opposed phase images, we recorded serum ferritin and results of oral glucose tolerance test (OGTT). Decreased L/M and P/M on at least the T2* sequence were noticed in 31/31 and 30/31 patients, respectively, but no correlation between P/M and L/M was found. Patients with pathologic OGTT displayed a higher degree of hepatic siderosis (p < 0.04) and signal drop of pancreas on opposed phase imaging (p < 0.025), implying fatty replacement of pancreas. P/M was neither correlated with glucose disturbances nor serum ferritin. Iron deposition in the pancreas cannot be predicted by the degree of hepatic siderosis in beta-thalassemia major. Fatty replacement of the pancreas is common and may be associated with glucose disturbances. (orig.)

    Full Text Available OBJECTIVE: This study was planned in order to determine the effect of C282Y mutation in development of secondary hemochromatosis in beta-thalassemia patients and to determine the prevalence and allele frequency of this mutation in a healthy control group. METHODS: Eighty-seven children and young adults (46 males and 41 females; mean age: 15.6±6.1 years, range: 3-30 years with beta-thalassemia major (BTM and 13 beta-thalassemia intermedia (BTI patients (6 males and 7 females; mean age: 19.6±3.5 years, range: 13-26 years were included in the study. The control group comprised 100 healthy blood donors. RESULTS: Neither heterozygous nor homozygous HFE gene C282Y mutation was detected in patients with BTM or BTI, or in control group. CONCLUSION: The C282Y mutation, which is supposed to be responsible for the majority of hereditary hemochromatosis, was not found to have a role in the development of hemochromatosis in beta-thalassemia patients and was not detected in a healthy Turkish population. However, research on larger cohorts of individuals is required in order to determine the exact prevalence of the HFE gene mutation in Turkish populations from diverse ethnic origins and whether it would have an impact on iron loading in thalassemic populations.

    To investigate the effects of different doses of antithymocyte globubin-fresenius (ATG-F) for allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with beta-thalassemia Major. Sixty-four children with beta-thalassemia major undergoing allo-HSCT were divided into two equal groups to receive ATG-F pretreatments at high (30 mg/kg) or low (15 mg/kg) doses as part of the conditioning regimen including mainly cyclophosphamide, busulfan, fludarabine, and thiotepa. The outcomes of the patients were compared between the two groups. No obvious difference were noted in the time to leukocyte and platelet engraftment between the two groups. The incidence of grade II-IV acute graft-versus-host disease (aGVHD) appeared to be higher in the low-dose group than in the high-dose group (12.5% vs 9.4%). The incidence of grade III-IV aGVHD was also higher in the low dose group (12.5% vs 6.3%), but the difference was not statistically significant. Application of high-dose ATG-F was associated with a higher rate of probable and possible fungal infection (P<0.05). The two doses of ATG-F is feasible as a part of the conditioning regimen for allo-HSCT in children with beta-thalassemia major.

    Full Text Available BACKGROUND: Thalassemia is the most common hereditary disease in the world. Thalassemic erythrocytes are exposed to higher oxidative stress and lipid peroxidation. The aim of this study was to investigate the effects of beta-carotene and vitamin E on erythrocytes lipid peroxidation in beta-thalassemia patients.
    METHODS: A prospective double-blind, placebo-controlled study of the effect of beta-carotene and vitamin E on lipid peroxidation in erythrocytes membranes was performed on 120 beta-thalassemia major patients in four groups. The patients were supplemented for 4 weeks as follows: group 1 with beta-carotene (13 mg/day, group 2 with vitamin E (550 mg/day, group 3 with beta-carotene plus vitamin E and group 4 with placebo. We prepared all capsules for 4 roups in the same shape and color. Measurements of serum beta-carotene and vitamin E were performed by high performance
    liquid chromatography. After preparation of ghost cells from blood specimens, malondialdehyde (MDA was determined as index of lipid peroxidation in erythrocytes membranes before and after treatment. RESULTS: The levels of serum beta-carotene and vitamin E were significantly lower and MDA concentrations in erythrocytes membranes were significantly higher in beta-thalassemia patients compared to controls (P<0.001. In groups that treated with vitamin supplements for 4-weeks, lipid peroxidation rates were significantly reduced after treatment (P<0.001, but in placebo group there was not significant difference (P>0.05.
    CONCLUSIONS: Our findings provide evidence that an oral treatment with beta-carotene and vitamin E can significantly reduce lipid peroxidation of erythrocytes membranes and could be useful in management of beta-thalassemia major patients. KEYWORDS: Beta-thalassemia major, beta-carotene, vitamin E, malondialdehyde, lipid peroxidation.

    Full Text Available Background The chronic genetic blood disorder, thalassemia, affects Quality of life (QOL negatively. Regarding this, if adolescences with thalassemia are treated well, they will grow into an adult who will have a good potential for participating in society. Objectives: to determine the strongest predictor of QOL, compare QOL between the adolescents with beta-type major and their peers in Abadan city. Materials and Methods This was a cross-sectional study; the population consisted of 65 beta thalassemia major patients and 65  healthy peers with the same ages as the witness group. The data collection tools included SF-36 questionnaire and a questionnaire for demographic information. Data analysis was performed using independent t-test, correlation and linear regression by SPSS-16. Results The results of the study revealed that there is a significant difference (P < 0.05 in the average quality of life between the two groups of the study. On the other hand, the results showed that there was a meaningful relation between different aspects of life quality and family history of thalassemia            (P< 0.05. Also, there was a negative correlation between quality of life and the frequency of blood transfusion per year (P< 0.05. Conclusion Adolescences with beta thalassemia major do not have a desirable quality of life, therefore, this fact shows the necessity of serious reforming in various fields of health care, treatment, family, social and financial support, and rehabilitation that need more attention from health care policymakers.

    Objective: To assess the efficacy, prospects and future of conservative management of beta thalassemia major patients in a developing country. Design: Patients registered at IHBTS were studied over a period of three years. They consented to being managed on moderate transfusion regimen, aiming to maintain a pre-transfusion haemoglobin(Hgb) level of 9.0 plus minus 1.0 g per dL. We studied their transfusion requirements, status for transfusion transmitted infections (TTls), serum ferritin levels and complications developing as a result of iron overload. Subjects: Initially all registered patients were included in this study. Sporadic patients as well as dropouts occurring due to any reason, (patients concurrently seeking treatment at other centres as well, or complying poorly to advised chelation therapy) were excluded from the study. The data presented here conforms to a cohort of 60 regular patients who adhered best to our selection criteria. Main Outcome Measures: 1) The study highlights the deficiencies and problems of conservative management for beta thalassemia major. 2) The major impact of our study is the message that conservative management in a poor country, like ours, is a no-win situation. 3) There is an urgent need to immediately start a prevention programme. Results: In the younger patients, blood consumption even on the moderate transfusion regimen is 120ml/kg/year, however with ascending age the consumption increases to 240ml/kg/year. A substantive number of the patients are either Hep C (35%) or Hep B (1.7%) positive. There are no HIV positive patients. Serum ferritin levels vary widely and could not be controlled due to poor compliance to chelation. 50% of the patients developed one or other complications of iron overload. The cost of treatment depending on the quality of care, is tremendous and beyond the reach of the common man. Conclusions: Conservative management may be the best alternative and at times the only hope for patients in our country

    Thalassemia syndrome has diverse clinical presentations and a global spread that has far exceeded the classical Mediterranean basin where the mutations arose. The mutations that give rise to either alpha or beta thalassemia are numerous, resulting in a wide spectrum of clinical severity ranging from carrier state to life-threatening, inherited hemolytic anemia that requires regular blood transfusion. Beta thalassemia major constitutes a remarkable challenge to health care providers. The complications arising due to the anemia, transfusional iron overload, as well as other therapy-related complications add to the complexity of this condition. To produce this consensus opinion manuscript, a PubMed search was performed to gather evidence-based original articles, review articles, as well as published work reflecting the experience of physicians and scientists in the Arabian Gulf region in an effort to standardize the management protocol.

    Full Text Available Thalassemia is a common hereditary hemoglobinopathy disorder that affects many organs in the body. Estimation of kidney function is important, as it is the vital organ that plays the major role in the elimination of accumulated iron as well as the chelating drugs that have to be used as therapy. Sixty- three patients aged 1-29 years, with a mean ± SD of 14 ± 6.7 years, affected with beta- thalassemia major in Tabriz Children′s Hospital were evaluated for their renal function on the basis of their age, serum iron, serum ferritin and serum creatinine levels along with two methods of estimating glomerular filtration rate (GFR; by Schwartz method for those under 18 years old and using Modification of Diet in Renal Disease (MDRD formula for those who were 18 years and above. Elevation of serum creatinine denoting renal dysfunction was not seen in our patients, but hyperfiltration was a common finding. An increasing GFR was observed, which corresponded to age, but no relationships were seen between serum iron, serum ferritin, regular blood transfusion, chelating therapy to GFR.

    Full Text Available Background: There currently is a lack of knowledge about the long-term survival of patients with beta thalassemia (BT, particularly in regions with low incidence of the disease. The aim of the present study was to determine the survival rate of the patients with BT major and the factors associated with the survival time. Methods: This retrospective cohort study was performed in Hamadan province, located in the west of Iran. The study included patients that referred to the provincial hospitals during 16 year period from 1997 to 2013. The follow up of each subject was calculated from the date of birth to the date of death. Demographic and clinical data were extracted from patients’ medical records using a checklist. Statistical analysis included the Kaplan-Meier method to analyze survivals, log-rank to compare curves between groups, and Cox regression for multivariate prognostic analysis. Results: A total of 133 patients with BT major were enrolled, 54.9% of whom were male and 66.2% were urban. The 10-, 20- and 30-year survival rate for all patients were 98.3%, 88.4% and 80.5%, respectively. Based on hazard ratio (HR, we found that accompanied diseases (P=0.01, blood type (P=0.03 and residency status (P=0.01 were significant predictors for the survival time of patients. Conclusion: The survival rate of BT patients has improved. Future researches such as prospective designs are required for the estimation of survival rate and to find other prognostic factors, which have reliable sources of data.

    Children suffering from beta-thalassemia major are reported to have endocrine abnormalities and growth retardation. This study was carried out to study the cause of their growth retardation and determine the extent and rate of endocrine complications. Twenty beta-thalassemic major pubertal children, with mean baemoglobin and ferritin concentration of 8.8±0.6 and 3.597± 1.931, respectively, and twenty pubertal control children were used in the study. The anthropometric measurements that carried out revealed significant low growth rate in patient groups in comparison with control. Patients divided into two groups; I) D-thal with delayed growth and II) S-thal with stunted growth. Basal serum thyoid hormones (T 3 and T 4 ) and thyroid stimulating hormone (TSH) were measured in patient groups and control group. T 3 showed highly significant decrease (P 4 showed non-significant change and TSH showed highly significant increase (P<0.001). Serum growth hormone showed significant lower concentrations in patient groups with values of 2.163±0.9 ng/ml, (P<0.01) and 1.832±1.9ng/ml, (P<0.01) for delayed growth thalassemic group (D-thal) and stunted growth thalassemic group (S-thal), respectively. Serum concentration of insulin growth factor-1 (IGF-1) hormone was studied. D-thal and S-thal had significant lower basal IGF-1 concentrationsof-58.44% (P<0.001) for D-thal and -64.37%, (P<0.001) for S-thal

    Full Text Available Background and Objectives: The aim of this study was to examine the arch dimensions of beta thalassemia major patients in comparison with normal individuals. Materials and Methods: Dental arch dimensions were compared between thalassemic patients and normal individuals in the age group of 12–16 years in the maxillary and mandibular arch corresponding to each other regarding age, sex and Angle's molar relationship. A total number of sixty cases in each group were taken. Maxillary and mandibular impressions were made with alginate for all the sixty participants in each group and poured with die stone. Measurement of inter incisor, inter canine, inter premolar and intermolar arch width, arch depth, right anterior, right posterior, left anterior, and left posterior arch length was carried out from each cast using digital Vernier caliper.Results: Unpaired t-test was used for comparison between the two groups. Statistically, a significant difference was found between the case and control groups in the maxillary arch in intercanine width, inter premolar width, intermolar width, right anterior arch length, right posterior arch length, and left anterior arch length. However, no statistically significant difference was found between the groups in inter incisor width, left posterior arch length, and arch depth in the maxillary arch. In the mandibular arch, statistically significant difference was found between the case and control groups in inter canine width, inter premolar width, inter molar width, and left anterior arch length. However, no statistically significant difference was found between the case and control groups in the mandibular arch in interincisor width, right anterior arch length, right posterior arch length, and left posterior arch length. Conclusion: Dental arch widths and arch lengths were significantly reduced in thalassemic patients as compared to normal individuals for the maxillary and mandibular arches.

    The possibility of increasing Hb F in vivo using drugs like 5-azacytidine, hydroxyurea, and butyrate has been established. However, in many cases this does not entail an increase in total hemoglobin. We report on a patient with Hb Lepore/beta-thalassemia being treated with hydroxyurea (30 mg/Kg/day) because of the presence of erythroid extramedullary masses with severe neurological abnormalities. During therapy the patient showed a remarkable improvement in neurological signs due to the reduction in extra-medullary masses, a significant increase in both total hemoglobin (from 5.8 to 9.7 g/dl) and Hb F (from 4.9 g/dl to 9.1 g/dl). The marked improvement in hemoglobin level in our patient with Hb Lepore/beta-thalassemia suggests gamma-globin gene activation due to the DNA structure determined by the crossover event.

    The endocrinological complications in β-thalassemia major patients do affect the life quality to a large extend. In this study, the endocrinological complications of 47 β-thalassemia patients, who have been followed-up at our hospital's pediatric hematology department, were evaluated. Out of β-thalassemia major cases included to this study, the 55.3% was male and 44.7% was female. The patients' mean levels of ferritin, whose mean age was 10.0 ± 4.5 years (2-20 years), were 2497 ± 1469 ng/mL (472-8558 ng/mL). At least one endocrinological pathology in 27 out of 47 (57.4%) and more than one endocrinological pathology in 14 out of 47 (29.7%) thalassemia patients were observed. The most frequently observed complication in followed-up cases was vitamin D insufficiency and deficiency (78.2%). The other complications in decreasing order were pubertal failure (41.6%), growth retardation (25.5%), decreased bone-mineral density (22.2%), secondary hyperparathyroidism (11.5%), overt hypothyroidism (4.25%), subclinical hypothyroidism (2.12%), and impaired glucose tolerance (2.12%). There was no statistically significant difference between serum mean ferritin level and endocrin complications (P > .05). Four patients (8.5%) had decreased signal intensity in pituitary magnetic resonance imaging (MRI) but this finding was not associated with ferritin levels (P = .87). MRI parameters were similar between patients with and without gonadal dysfunction. Mean height of the pituitary gland was 4.98 ± 1.1 mm (3-9 mm) and this was similar to those normal values in the literature. Ferritin levels were not correlated with pituitary height (P > .05). Beta thalassemia major, having the potential of leading to multisystemic complications, is a chronic disease that should be treated and followed-up by a multidisciplinary approach. Due to frequently encountered endocrinological complications, beta thalassemic patients should be followed-up regularly by hematology and endocrinology

    Extramedullary hematopoiesis (EMH) occurs in patients with various hematologic disorders involving a chronic increase in the production of red blood cells, and is often associated polycythemia vera and sickle cell anaemia, but is less common with thalassemia especially with hemoglobin E-beta thalassemia. Spinal cord compression due to EMH is a extremely rare complication of thalassemia and may present with paraparesis or paraplegia with or without sensory impairment. Treatment options mostly include surgery and/or radiotherapy. Whereas cases presenting with paraplegia have been treated with either surgery or radiotherapy with equal frequency and efficacy, almost all reported cases with paraplegia have been treated with surgery with or without radiation therapy. We hereby report a case of hemoglobin E-beta thalassemia with paraplegia treated successfully with radiotherapy.

    This study aimed to detect the most common HFE gene mutations (C282Y, H63D, and S56C) in Egyptian beta thalassemia major patients and its relation to their iron status. The study included 50 beta thalassemia major patients and 30 age and sex matched healthy persons as a control group. Serum ferritin, serum iron and TIBC level were measured. Detection of the three HFE gene mutations (C282Y, H63D and S65C) was done by PCR-RFLP analysis. Confirmation of positive cases for the mutations was done by sequencing. Neither homozygote nor carrier status for the C282Y or S65C alleles was found. The H63D heterozygous state was detected in 5/50 (10%) thalassemic patients and in 1/30 (3.3%) controls with no statistically significant difference between patients and control groups (p = 0.22). Significantly higher levels of the serum ferritin and serum iron in patients with this mutation (p = 001). Our results suggest that there is an association between H63D mutation and the severity of iron overload in thalassemic patients.

    The new three-dimensional speckle tracking echocardiography (3DSTE) may enable comprehensive quantification of global left ventricular (LV) myocardial mechanics. Twenty-four patients aged 29.3 ± 5.2 years and 22 controls were studied. 3DSTE was performed to assess LV 3D global strain, twist and torsion, ejection fraction, and systolic dyssynchrony index (SDI). The LV SDI was calculated as % of SD of times-to-peak strain of 16 segments/RR interval. The global performance index (GPI) was calculated as (global 3D strain·torsion)/SDI. Area under the receiver operating characteristic curve (AUC) was calculated to determine the capability of 3DSTE parameters to discriminate between patients with (cardiac magnetic resonance T2* overload. Compared with controls, patients had significantly lower LV global 3D strain (P overload. The LV composite index of strain, torsion, and dyssynchrony derived from 3DSTE enables sensitive detection of myocardial iron overload in patients with thalassemia. © 2016, Wiley Periodicals, Inc.

    2003-01-01

    Our objective was to study, in thalassemic patients, if hepatic siderosis evaluated by MRI could predict the pituitary iron overload. In 36 thalassemic patients (age range 6-44 years, mean age 21.7 years) the liver/fat ratio (L/F), the pituitary/fat ratio (P/F), the liver and pituitary T2 relaxation times were evaluated, by using a multiecho spin-echo sequence. Serum ferritin levels were measured and an extensive endocrine evaluation was performed. The L/F, the P/F and pituitary T2 showed a good correlation with serum ferritin (r=-0.55, r=-0.55 and r=-0.53, respectively; p<0.01). Liver T2 did not show significant correlation with serum ferritin. The variability of L/F explained only the 10.8% of the variability of pituitary T2 and of the P/F. When ferritin was added to the model it predicted only the 26.85% and the 30.8% of the variability of pituitary T2 and of the P/F, respectively. The P/F and pituitary T2 were lower in patients with hypogonadotropic hypogonadism (group 1) compared with those without pituitary dysfunction (group 2). No significant differences of L/F were found between the two groups. Hepatic iron overload evaluated by MR is a poor predictor of pituitary siderosis. The MR studies of the pituitary gland might be necessary to evaluate the pituitary iron overload. (orig.)

    Full Text Available Thalassemia is a globin gene disorder that results in a diminished rate of synthesis of one or more of the globin chains. About 1.5% of the global population (80 to 90 million people are carriers of beta Thalassemia. More than 200 mutations are described in beta thalassemia. However not all mutations are common in different ethnic groups. The only effective way to reduce burden of thalassemia is to prevent birth of homozygotes. Diagnosis of beta thalassemia can be done by fetal DNA analysis for molecular defects of beta thalassemia or by fetal blood analysis. Hematopoietic stem cell transplantation is the only available curative approach for Thalassemia. Many patients with thalassemia in underdeveloped nations die in childhood or adolescence. Programs that provide acceptable care, including transfusion of safe blood and supportive therapy including chelation must be established.DOI: http://dx.doi.org/10.3126/jpn.v4i8.11609 Journal of Pathology of Nepal; Vol.4,No. 8 (2014 663-671

    Full Text Available Beta-thalassemia is a genetic, red blood cell disorder affecting the beta-globin chain of the adult hemoglobin gene. This results in excess accumulation of unpaired alpha-chain gene products leading to reduced red blood cell life span and the development of severe anemia. Current treatment of this disease involves regular blood transfusion and adjunct chelation therapy to lower blood transfusion–induced iron overload. Fetal hemoglobin switching agents have been proposed to treat genetic blood disorders, such as sickle cell anemia and beta-thalassemia, in an effort to compensate for the dysfunctional form of the beta-globin chain in adult hemoglobin. The rationale behind this approach is to pair the excess normal alpha-globin chain with the alternative fetal gamma-chain to promote red blood cell survival and ameliorate the anemia. Reprogramming of differentiation in intact, mature, adult white blood cells in response to inclusion of monoclonal antibody CR3/43 has been described. This form of retrograde development has been termed “retrodifferentiation”, with the ability to re-express a variety of stem cell markers in a heterogeneous population of white blood cells. This form of reprogramming, or reontogeny, to a more pluripotent stem cell state ought to recapitulate early hematopoiesis and facilitate expression of a fetal and/or adult program of hemoglobin synthesis or regeneration on infusion and subsequent redifferentiation. Herein, the outcome of infusion of autologous retrodifferentiated stem cells (RSC into 21 patients with beta-thalassemia is described. Over 6 months, Infusion of 3-h autologous RSC subjected to hematopoietic-conducive conditions into patients with beta-thalassemia reduced mean blood transfusion requirement, increased mean fetal hemoglobin synthesis, and significantly lowered mean serum ferritin. This was always accompanied by an increase in mean corpuscular volume (MCV, mean corpuscular hemoglobin (MCH, and mean

    This study aimed at describing the magnetic resonance (MR) imaging features of the adrenal glands in beta-thalassemic patients and at investigating the relation between adrenal and hepatic siderosis. Adrenal signal intensity (SI) was retrospectively assessed on abdominal MR studies of 35 patients with beta-thalassemia major undergoing quantification of hepatic siderosis and 12 healthy controls, using T1- (120/4/90), intermediate - (120/4/20), and T2*- (120/15/20) weighted GRE sequences. Adrenal SI was graded as grade 0 (normal SI on all sequences), grade 1 (hypointensity on T2* alone), or grade 2 (hypointensity on at least T2*). Adrenal size was measured in the thalassemic patients and compared with normative data. Liver-to-muscle (L/M) SI ratios, expressing hepatic siderosis, were estimated on each sequence. Serum ferritin levels were recorded. Adrenal hypointensity (grades 1 and 2) was noted in 24/35 (68.6%) patients. L/M ratios correlated significantly with adrenal SI in all sequences. Patients with grade 1 and grade 2 adrenal SI had significantly decreased L/M ratios compared with grade 0. Serum ferritin correlated significantly with L/M values but not with adrenal SI. Adrenal size was within normal limits. Diffuse hypointensity in normal-sized adrenals is a common MR finding in beta-thalassemic patients and correlates with the degree of hepatic siderosis. (orig.)

    Endocrine complications due to haemosiderosis are present in a significant number of patients with beta-thalassemia major (BTM) worldwide and often become barriers in their desire for parenthood. Thus, although spontaneous fertility can occur, the majority of females with BTM is infertile due to hypogonadotropic hypogonadism (HH) and need assisted reproductive techniques. Infertility in these women seems to be attributed to iron deposition and iron-induced oxidative stress (OS) in various endocrine organs, such as hypothalamus, pituitary, and female reproductive system, but also through the iron effect on other organs, such as liver and pancreas, contributing to the impaired metabolism of hormones and serum antioxidants. Nevertheless, the gonadal function of these patients is usually intact and fertility is usually retrievable. Meanwhile, a significant prooxidants/antioxidants imbalance with subsequent increased (OS) exists in patients with BTM, which is mainly caused by tissue injury due to overproduction of free radicals by secondary iron overload, but also due to alteration in serum trace elements and antioxidant enzymes. Not only using the appropriate antioxidants, essential trace elements, and minerals, but also regulating the advanced glycation end products, could probably reduce the extent of oxidative damage and related complications and retrieve BTM women's infertility.

    Full Text Available Abstract Beta-thalassemias are a group of hereditary blood disorders characterized by anomalies in the synthesis of the beta chains of hemoglobin resulting in variable phenotypes ranging from severe anemia to clinically asymptomatic individuals. The total annual incidence of symptomatic individuals is estimated at 1 in 100,000 throughout the world and 1 in 10,000 people in the European Union. Three main forms have been described: thalassemia major, thalassemia intermedia and thalassemia minor. Individuals with thalassemia major usually present within the first two years of life with severe anemia, requiring regular red blood cell (RBC transfusions. Findings in untreated or poorly transfused individuals with thalassemia major, as seen in some developing countries, are growth retardation, pallor, jaundice, poor musculature, hepatosplenomegaly, leg ulcers, development of masses from extramedullary hematopoiesis, and skeletal changes that result from expansion of the bone marrow. Regular transfusion therapy leads to iron overload-related complications including endocrine complication (growth retardation, failure of sexual maturation, diabetes mellitus, and insufficiency of the parathyroid, thyroid, pituitary, and less commonly, adrenal glands, dilated myocardiopathy, liver fibrosis and cirrhosis. Patients with thalassemia intermedia present later in life with moderate anemia and do not require regular transfusions. Main clinical features in these patients are hypertrophy of erythroid marrow with medullary and extramedullary hematopoiesis and its complications (osteoporosis, masses of erythropoietic tissue that primarily affect the spleen, liver, lymph nodes, chest and spine, and bone deformities and typical facial changes, gallstones, painful leg ulcers and increased predisposition to thrombosis. Thalassemia minor is clinically asymptomatic but some subjects may have moderate anemia. Beta-thalassemias are caused by point mutations or, more rarely

    2013-09-01

    Full Text Available Hepatic calcification is usually associated with infectious, vascular, or neoplastic processes in the liver. We report the first case of beta-thalassemia major with isolated diffuse hepatic calcification in a 23 year old woman, who had been transfusion-dependent since the age of 6 months. She was referred to our center with a chief complaint of abdominal pain. Computed tomography scan of the abdomen revealed diffuse hepatic calcification in the right, left, and caudate lobes of the liver. Her medical history disclosed hypoparathyroidism as well as chronic hepatitis C virus infection, which was successfully treated but led to early micronodular cirrhosis on liver biopsy. Other studies done to search for the cause of hepatic calcification failed to reveal any abnormalities. We suspect that hypoparathyroidism caused liver calcification, and should be, therefore, considered in the differential diagnosis of hepatic calcification if other causative factors have been ruled out.

    The purpose of this study is to describe the MR imaging features of bone marrow in beta-thalassemia major and investigate their relation to ferritin, liver and spleen siderosis. Spinal bone marrow was prospectively assessed on abdominal MR studies of 40 transfused beta-thalassemic patients and 15 controls using T1-w, Pd, T2*-w Gradient Echo (GRE) and T1-w turbo Spin Echo (TSE) sequences. Signal intensity (SI) ratios of liver, spleen and bone marrow to paraspinous muscles (L/M, S/M, B/M respectively) and the respective T2 relaxation rates (1/T2) were calculated. Serum ferritin levels were recorded. Bone marrow hypointensity in at least T2*-w GRE sequence was noted in 29/40 (72.5%) patients. Eleven/40 patients exhibited normal B/M on all MR sequences. Five/40 patients had normal B/M and low L/M. B/M correlated with L/M in T1-w TSE sequence only (r = 0.471, p = 0.05). B/M correlated with S/M and mean ferritin values in all sequences (r > 0.489, p - 0.496, p < 0.03 respectively). Marrow 1/T2 did not correlate with ferritin values or liver and spleen 1/T2. B/M in transfused beta-thalassemic patients is related to splenic siderosis and ferritin levels. Although marrow is usually hypointense, it may occasionally display normal SI coexisting with liver hypointensity, a pattern typical of primary hemochromatosis. (orig.)

    The purpose of this study is to describe the MR imaging features of bone marrow in beta-thalassemia major and investigate their relation to ferritin, liver and spleen siderosis. Spinal bone marrow was prospectively assessed on abdominal MR studies of 40 transfused beta-thalassemic patients and 15 controls using T1-w, Pd, T2*-w Gradient Echo (GRE) and T1-w turbo Spin Echo (TSE) sequences. Signal intensity (SI) ratios of liver, spleen and bone marrow to paraspinous muscles (L/M, S/M, B/M respectively) and the respective T2 relaxation rates (1/T2) were calculated. Serum ferritin levels were recorded. Bone marrow hypointensity in at least T2*-w GRE sequence was noted in 29/40 (72.5%) patients. Eleven/40 patients exhibited normal B/M on all MR sequences. Five/40 patients had normal B/M and low L/M. B/M correlated with L/M in T1-w TSE sequence only (r = 0.471, p = 0.05). B/M correlated with S/M and mean ferritin values in all sequences (r > 0.489, p < 0.01 and r > - 0.496, p < 0.03 respectively). Marrow 1/T2 did not correlate with ferritin values or liver and spleen 1/T2. B/M in transfused beta-thalassemic patients is related to splenic siderosis and ferritin levels. Although marrow is usually hypointense, it may occasionally display normal SI coexisting with liver hypointensity, a pattern typical of primary hemochromatosis. (orig.)

    Full Text Available 35 unrelated individuals were studied for characterization as either heterozygous or homozygous for beta-thalassemia. Molecular analysis was done by PCR/RFLP to detect the mutations most commonly associated with beta-thalassemia (β0IVS-I-1, β+IVS-I-6, and β039. In the patients who showed none of these mutations, the beta-globin genes were sequenced. Of the 31 heterozygous patients, 13 (41.9% had the β+IVS-I-6 mutation, 15 (48.4% the β0IVS-I-1 mutation, 2 (6.5% the β+IVS-I-110 mutation and 1 (3.2% the β+IVS-I-5 mutation. IVS-I-6 was detected in the four homozygotes. The mutation in codon 39, often found in previous studies in Brazil, was not detected in the present case. This is the first study aiming at identifying mutations that determine beta-thalassemia in the state of Rio Grande do Norte.

    Extramedullary hematopoiesis (EMH) is evidenced by erythropoietic masses, which occurs as a compensatory mechanism to overcome hypoxia during chronic anemia. EMH masses in spinal cord could lead to cord compression and neurological symptoms. Besides transfusion, radiotherapy, and surgery, hydroxyurea (HU) is also a treatment strategy in EMH. We described four cases of beta thalassemia with EMH who were treated with HU as a monotherapy. INTERVENTION (AND TECHNIQUE): HU therapy was done in all patients without any transfusion during therapy. HU is a good treatment option for patients with EMH and it could be a substitute for radiotherapy and invasive surgery or regular blood transfusion.

    Full Text Available Background: Thalassemia is a chronic disease that it leads to psychological and social problems for parents. Mothers are at markedly increased risk of suffering from psychological distress and depression because they usually take on a considerable part of extra care that their children need.This study was designed to determine prevalence and intensity of depression in mothers with a thalassemic child. Material and Methods: In this cross – sectional study, 65 mothers of children with thalassemia major (case group and 65 mothers of children without thalassemia major (control group were assessed using the Beck Depression Inventory (BDI. Data were analyzed by using SPSS (v 16.0 for windows. Results: Prevalence of depression was significantly higher in case group than that in control group (84.6%vs. 56.9%, p <0.05. Moderate depression had a highest prevalence in the both groups (33.4% in case group and 30.8% in control group. Prevalence of severe depression in case group was markedly higher than that in control group (29.2% vs. 3.1% p<0.05. There was a significant difference between intensity of depression in mothers of case group that had another child with beta-thalassemia major (p<0.05. Conclusion: Mothers of children with thalassemia major are vulnerable to depression. They need psychosocial support to promote their health.

    A health-promoting lifestyle (HPL) is a factor that affects the quality of life (QoL) in patients with beta-thalassemia (β-thalassemia). Due to the lack of studies of this issue, this study aimed to determine the association between HPL and QoL among adults with β-thalassemia. This cross-sectional (descriptive-analytic) study was conducted among 389 adult patients with β-thalassemia in Tehran, Iran. The research instrument included a questionnaire consisting of three parts: demographic items, the Short-Form Health Survey and the Health-Promoting Lifestyle Profile. The data were analyzed using SPSS version 23.0. The results were considered significant at the conventional pthalassemia; these four dimensions explained 37.9% of the variance in QoL. QoL and HPL were not at acceptable levels among patients with thalassemia. Therefore, educational interventions emphasizing spiritual growth, physical activity, and interpersonal relations are necessary for patients with thalassemia.

    To study the ethnic and geographic distribution of Beta-thalassemia amongst the patients included and to study the effect of consanguinity in promoting this disease. Also, to establish the safety of CVS when used as a pre-natal diagnostic tool in aiding the early diagnosis of Beta-thalassemia in selected patients. Study Design: Descriptive Study. Place and Duration of Study: PNS Shifa Karachi, from Jan 2008 to Dec 2008. Patients and Methods: A total of 223 women out of 240 that were referred from all over Sindh to PNS Shifa Hospital Karachi for susceptible gene mutations participated in the study. The standard procedure that was used in this study was trans-abdominal aspiration of chorionic villi through suction needle. The samples were then sent for further analysis to the Pathology Department at PNS Shifa Hospital Karachi. Results: In our study population Beta-thalassemia was most prevalent in Sindhi 107 (48%) followed by Punjabi 46 (21%), 27 (12%) Pathan, and 43 (19%) Balochi. Out of 223 women, 95 were of thalassemia trait, while 85 were of thalassemia major. Fifty five percent of thalassemia trait and 56% of thalassemia major fetus parents were first cousins. The rate of pregnancy loss after performing CVS was 2.0% with no complications reported. Conclusion: It is concluded that highest percentage of thalassemia is in first cousins and sindhi origin families are mostly affected. However CVS is a safe and effective tool for prenatal diagnosis and subsequent counselling in selected couples. (author)

    To determine the regional and ethnic distribution of beta thalassemia mutation and the effect of consanguinity in patients referred for prenatal diagnosis of beta b-thalassemia and to target the high risk population for screening. A total of 499 couples were referred to Gentec Lab., Lahore, from all over Pakistan for prenatal diagnosis of b-thalassemia. After counseling, chorionic villus sampling was done between 10-16 weeks of gestation. DNA analysis was done by Amplification Refractory Mutation System (ARMS) for type of mutation in the Armed Forces Institute of Pathology, Rawalpindi. Ethnicity, race and consanguineous relationship of parents was determined.b-thalassemia was prevalent in Punjabis (60.7%) followed by Saraikees (25.5%). Castewise it was most frequent in Rajputs followed by Jatts, Arain, Sheikhs and Pathans. 56.7% of the couples were first cousins and 19.8% were relatives. The commonest mutations were Frameshift 8-9 (Fr8-9) 33.5%, Intervening Sequence 1-5 (IVS 1-5) 17.2%, Fr4142 - 8%, IVS 1-1 - 5.2%, Deletion 619 (Del 619) 4.2% and Codon 5 (Cd 5) - 4.2%. In samples sent for analysis, 53.1% turned out to be carriers (trait), 25.3% were diseased (thalassemia major) and 21.6% were normal. P-value of all results was less than 0.001. In this series, the highest frequency was found in Punjabi Rajputs. The commonest mutation was Fr 8-9. Most parents were first cousins. Premarital thalassemia carrier testing can effectively reduce the disease. (author)

    Multiple risk factors contribute to cognitive impairment in children with β-thalassemia major. For a more refined understanding of this issue, we attempted to evaluate cognitive function in β-thalassemia major patients and identify the relationship between possible cognitive dysfunction and the following: demography, transfusion and chelation characteristics, iron overload, and disease complications. We studied 100 β-thalassemia major children and 100 healthy controls who matched well in terms of age, sex, and socioeconomic status. All participants underwent psychometric assessment using Wechsler Intelligence Scale for Children-Third Edition, Arabic version. The mean Full-Scale IQ and Performance IQ of patients were significantly lower than those of controls, whereas no significant difference was found for Verbal IQ. No significant relationship existed between IQ and any of the assessed parameters. We concluded that Performance IQ, not Verbal IQ, was significantly affected in β-thalassemia major patients, but there was no clear association between IQ and any of the parameters. © The Author(s) 2014.

    The haematologic disorder b-thalassemia major is common in Pakistan. We describe a patient with undiagnosed thalassemia presenting with hypertension and convulsions and found to have cerebral haemorrhage on neuro-imaging. He had been transfused 2 weeks before this illness. Our experience is similar to a few case reports described in literature that were found to have cerebral haemorrhages post-mortem after a similar clinical presentation. All patients had a blood transfusion within 2 weeks prior to the presentation so association with transfusion has been proposed. We have reviewed the several mechanisms presented and discussed the findings. (author)

    We describe a 16 year-old male with β thalassemia major and gait disturbances that had not been given blood transfusions due to a severe childhood transfusion reaction. Thoracic spine MRI demonstrated hematopoietic marrow throughout the spine and epidural masses causing cord compression consistent with extramedullary hematopoiesis (EMH). After treatment with steroids, radiotherapy and monitored blood transfusions, the patient demonstrated significant improvement of his paraspinal lesions and near complete resolution of his neurological symptoms. While EMH causing cord compression in adolescents is rare in the current era of bone marrow transplantation or chronic transfusions, it should be considered when thalassemia major patients present with neurological deficits. The well defined imaging features of EMH can play a central role in its diagnosis and management, especially because surgical and / or radiotherapeutic intervention are often considered in cases of failed medical treatment.

    Iron chelation therapy (ICT) with deferoxamine (DFO), the current standard for the treatment of iron overload in patients with transfusion-dependent disorders such as beta-thalassemia, requires regular subcutaneous or intravenous infusions. This can lead to reduced quality of life and poor adherence, resulting in increased morbidity and mortality in iron-overloaded patients with beta-thalassemia. Deferasirox is an orally administered iron chelator that has been approved for use in the United States, Switzerland, and other countries. This analysis was conducted to compare patient-reported outcomes (PROs) during receipt of DFO infusions or once-daily oral therapy with deferasirox (ICL670). PROs were prospectively evaluated as part of a randomized, Phase III study comparing the efficacy and safety profile of DFO 20 to 60 mg/kg per day with those of deferasirox 5 to 30 mg/kg per day in patients (age > or =2 years) with beta-thalassemia who were receiving regular transfusions and had a liver iron concentration of > or =2 mg/g dry weight. PRO questionnaires were completed by patients or a parent or legal guardian at baseline, week 4, week 24, and end of study (EOS). Patients assessed their level of satisfaction with study treatment (very satisfied, satisfied, neutral, dissatisfied, or very dissatisfied) and rated its convenience (very convenient, convenient, neutral, inconvenient, or very inconvenient). Time lost from normal activities due to ICT in the previous 4 weeks was recorded using a single global assessment. At week 4, patients who had previous experience with DFO were asked to indicate their preference for treatment (ICT received before the study, ICT received during the study, no preference, or no response) and the reason for that preference. At EOS, all patients were asked if they would be willing to continue using the ICT they had received during the study. All study analyses were performed in all patients who received at least 1 dose of study medication

    We ought to obtain data on the prevalence of the newly discovered tranfusion transmittable hepatitis G virus in polytransfused b- thalassemia major children. Each individual had received multiple blood transfusions, from 12 to 36 per year. No documentation of prior hepatic infection was available. Serum samples were collected prospectively from the randomly selected subjects and were analyzed for HGV RNA by polymerase chain reaction using primer specific for two different regions of the HGV genome. Among the 100 individuals examined 21 were positive for HGV RNA. Four patients had evidence of dual infection, both HGV RNA and HCV RNA were isolated from their sera. While in one sample presence of both HGV RNA and HBV DNA was established. Only one child was positive for hepatitis E antibodies. The sera of 10 children were reactive for hepatitis B surface antigen whereas 35 individuals were positive for hepatitis C virus antibody. The ALT levels were variable in HGV infected children. Four out of 16 (25%) showed peak ALT levels of 218 IU/I, 8/16 (50%) children demonstrated slightly elevated ALT levels whereas 25% individuals showed normal ALT levels. Alkaline Phosphatase levels were elevated in 90% of the children and 20% patients of this series also had higher GGT levels. The observed AP levels were not statistically different among HGV, HGV/HCV or HGV/HBV groups. Even though the ALT levels were deranged in the children with HGV alone but none of the children had demonstrated symptoms of liver disease, their direct and total bilirubin levels were normal and no complain of jaundice was recorded. In conclusion, our findings suggested that like other blood borne hepatic viruses, HGV is also prevalent in the high risk group of multiple transfused patients in Pakistan but our results support the absence of any causal relationship between HGV and hepatitis.

    Full Text Available Abstract Background The combination of transfusion and chelation therapy has dramatically extended the life expectancy of thalassemic patients. The main objective of this study is to determine the prevalence of prominent thalassemia complications. Methods Two hundred twenty patients entered the study. Physicians collected demographic and anthropometric data and the history of therapies as well as menstrual histories. Patients have been examined to determine their pubertal status. Serum levels of 25(OH D, calcium, phosphate, iPTH were measured. Thyroid function was assessed by T3, T4 and TSH. Zinc and copper in serum were determined by flame atomic absorption spectrophotometry. Bone mineral density (BMD measurements at lumbar and femoral regions have been done using dual x-ray absorptiometry. The dietary calcium, zinc and copper intakes were estimated by food-frequency questionnaires. Results Short stature was seen in 39.3% of our patients. Hypogonadism was seen in 22.9% of boys and 12.2% of girls. Hypoparathyroidism and primary hypothyroidism was present in 7.6% and 7.7% of the patients. About 13 % of patients had more than one endocrine complication with mean serum ferritin of 1678 ± 955 micrograms/lit. Prevalence of lumbar osteoporosis and osteopenia were 50.7% and 39.4%. Femoral osteoporosis and osteopenia were present in 10.8% and 36.9% of the patients. Lumbar BMD abnormalities were associated with duration of chelation therapy. Low serum zinc and copper was observed in 79.6% and 68% of the study population respectively. Serum zinc showed significant association with lumbar but not femoral BMD. In 37.2% of patients serum levels of 25(OH D below 23 nmol/l were detected. Conclusion High prevalence of complications among our thalassemics signifies the importance of more detailed studies along with therapeutic interventions.

    Objective: To share the preliminary data on stem cell transplantation in Pakistan. Results: Engraftment was achieved in all patients except one who required a second dose of bone marrow graft on day +21. Median time to achieve absolute neutrophil count of > 0.5 x 10/sup 9/ /l was 9.0 days (range 8 - 31 days) and platelet count of > 20 x 10/sup 9/ /l was 14 days (12 - 35 days). Acute GVHD was seen in 3 patients, one patient had grade IV gut GVHD; another patient had grade III gut GVHD while third patient had grade II skin GVHD. Median hospital stay was 29 days. Six patients were well and transfusion independent 3 to 36 months post transplant. One episode of primary graft failure required a second dose of bone marrow harvest. Another episode of graft rejection received two doses of donor lymphocytes infusion. There were 4 deaths due to grade IV gut GVHD because of uncontrolled systemic Candida infection and one due to hepatic veno-occlusive (VOD) disease. Conclusion: Allogeneic peripheral blood stem cell transplantation can be safely and economically carried out in Pakistan. Although there had been 4 deaths during 36 months follow-up, with increasing understanding and experience the outcome is expected to improve. (author)

    Full Text Available Background: Hereditary hemochromatosis is the most frequent cause of primary iron overload that is associated with HFE gene’s mutation especially the C282Y mutation. The interaction between hemoglobin chain synthesis’ disorders and the C282Y mutation may worsen the clinical picture of beta-thalassemia major (β-TM. Aim: To establish the prevalence of the C282Y mutations in Egyptian β-TM patients and to address its adverse effects. Methods: Two-hundred and five β-TM patients were recruited and divided into two groups based on their serum ferritin (SF; group I (N = 125 (SF ≤ 2500 ng/dl and group II (N = 80 (SF > 2500 ng/dl. All patients were subjected to clinical and laboratory assessment with special emphasis on iron overload complications. Genotyping was assessed by polymerase chain reaction for detection of C282Y mutation in HFE gene. Results: The C282Y mutation was not detected in the studied β-TM neither in homozygous nor heterozygous state. There were several iron overload complications including cardiac complication (9.1%, liver disease (36.6%, delayed puberty (56.6%, primary (35.71% and secondary amenorrhea (21.42%, short stature (27.3%, diabetes (3.4%, neutropenia (9.7%, arthralgia (10.2%, gastrointestinal (21.1%, depression (2.9% and others (12.05%. Group I showed a statistically significant lower rate of taking iron-rich diet when compared to group II. Group II showed significant longer mean duration of disease, higher total transfusion rate per life, lower mean HbF% level, higher mean HbA% level, and higher rate of elevated liver enzymes than patients with SF ≤ 2500 ng/dl. Conclusion: The C282Y mutation was not detected in the studied cohort of Egyptian β-TM patients neither in homozygous nor heterozygous state in spite of manifestations of iron overload complications.

    Patient-reported outcomes of once-daily oral deferasirox (Exjade) in iron-overloaded patients with beta-thalassemia not achieving successful chelation with prior deferoxamine and/or deferiprone were investigated in a prospective, open-label, 1-year, multicenter study in the Middle East (ESCALATOR). The initial dose of deferasirox was 20 mg/kg/day, with subsequent dose adjustments. At baseline and the end of study (EOS), patients (n = 237) completed a 5-point rating scale for treatment satisfaction and convenience, and recorded time lost to treatment. At EOS, 90.7% of patients were 'satisfied'/'very satisfied' with their iron chelation therapy (ICT) versus 23.2% at baseline. 92.8% (EOS) versus 21.5% (baseline) of patients considered their therapy to be 'convenient'/'very convenient'. Time lost to therapy for daily activities was substantially reduced (3.2 +/- 8.6 [mean +/- SD; EOS] vs. 30.1 +/- 44.2 [baseline] h/month). Patients reported greater satisfaction and convenience, and lower impact on daily activities, with deferasirox than with previous ICT. This may help improve adherence to lifelong ICT in iron-overloaded beta-thalassemia patients. 2010 S. Karger AG, Basel.

    Thalassemia is a heterogeneous disorder and several genetic factors influence the severity of thalassemia. An accurate and early diagnosis of a mild thalassemia genotype helps to avoid unnecessary transfusion and its complications. The aim of this study is to identify the association between XmnI polymorphism and disease severity in patients with ?-thalassemia from northern Pakistan. Methods: The cross sectional study was conducted at the Department of Haematology, Armed Forces Institute of Pathology (AFIP) Rawalpindi, from September 2006 to June 2009. A total of 90 subjects including 30 with thalassemia major, 30 with thalassemia intermedia and 30 normal individuals were studied. DNA from each subject was tested for 15 ?-thalassemia mutations and the presence of XmnI polymorphism using Amplification Refractory Mutation System and Restriction Fragment Length Polymorphism respectively. Results: One normal and one thalassemia major subject were found to be positive for homozygous and heterozygous XmnI polymorphism respectively. Among the thalassemia intermedia group, XmnI polymorphism was found in 12/30 patients, of whom 10 were homozygous and 2 were heterozygous for it. Conclusion: XmnI polymorphism is an important genotypic factor in Pakistani population for making a prospective diagnosis of thalassemia intermedia and predicting the severity of the disease.

    Full Text Available Previous studies have demonstrated impaired ventricular repolarization in patients with β-TM. However, the effect of iron overload with cardiac T2* magnetic resonance imaging (MRI on cardiac repolarization remains unclear yet. We aimed to examine relationship between repolarization parameters and iron loading using cardiac T2* MRI in asymptomatic β-TM patients. Twenty-two β-TM patients and 22 age- and gender-matched healthy controls were enrolled to the study. From the 12-lead surface electrocardiography, regional and transmyocardial repolarization parameters were evaluated manually by two experienced cardiologists. All patients were also undergone MRI for cardiac T2* evaluation. Cardiac T2* score <20 msec was considered as iron overload status. Of the QT parameters, QT duration, corrected QT interval, and QT peak duration were significantly longer in the β-TM group compared to the healthy controls. Tp−Te and Tp−Te dispersions were also significantly prolonged in β-TM group compared to healthy controls. (Tp-Te/QT was similar between groups. There was no correlation between repolarization parameters and cardiac T2* MRI values. In conclusion, although repolarization parameters were prolonged in asymptomatic β-TM patients compared with control, we could not find any relation between ECG findings and cardiac iron load.

    Inheritance of the gene for betaE-globin is associated with hypochromia and microcytosis, reminiscent of typical heterozygous beta-thalassemia. Patients with hemoglobin (Hb)E-beta-thalassemia exhibit clinical phenotypes of severe beta-thalassemia, a circumstance not encountered in other compound heterozygous states for structural beta-chain mutations and beta-thalassemia. We have analyzed the kinetics of globin synthesis and the levels of globin messenger (m) RNA accumulation in patients with...

    Introduction: Thalassemia is the most common hereditary blood disorder in the world. Iran is located on the thalassemic belt and there is a high prevalence of the hepatosplenomegaly in beta thalassemia minor patients which is reported to be very variable. The goal of this research was to study the frequency of these signs in the cases with beta thalassemia minor patients in Iran. Materials and methods: Two hundred and fifty-nine cases that referred to center for pre-marriage tests were divided into two groups according to their MCV, MCH, and HbA2 (beta thalassemia minor cases and control groups). Liver and spleen sizes were determined by ultrasonographic method and the two groups were compared with each other. Results: Average spleen volumes in case and control groups were 163.48 {+-} 133.97 and 126.29 {+-} 53.98 mm{sup 3}, respectively. Average spleen lengths in case and control groups were 10.71 {+-} 1.52 and 10.60 {+-} 5.4 cm, respectively. Conclusion: In the regions with high frequency of beta thalassemia, in case of finding large spleen size in the ultrasonography, a probable harmless differential diagnosis will be beta thalassemia minor that is not indicative of any serious disease. Volumetric measurement of spleen is more reliable for detection of splenomegaly in these patients.

    Moyamoya syndrome (MMS) is a progressive disorder. We report a 19-year-old boy with beta-thalassemia who presented with a left hemiparesis. Brain MRI showed old middle cerebral artery and left frontal subcortical white matter infarcts. Brain magnetic resonance angiography and digital subtraction angiography revealed occlusion of the bilateral internal carotid arteries with a rich network of basal collateral vessels. To our knowledge this is the third report of beta-thalassemia intermedia and MMS, and the first report of a patient in Turkey. It emphasizes the potential for cerebral infarct due to anemia, protein S and thrombocytosis.

    Full Text Available Background: Several studies have evaluated the oxidant and antioxidant status of thalassemia patients but most focused mainly on the severe and intermediate states of the disease. Moreover, the oxidative status has not been evaluated for the different beta-thalassemia mutations. Objective: To evaluate lipid peroxidation and Trolox equivalent antioxidant capacity in relation to serum iron and ferritin in beta thalassemia resulting from two different mutations (CD39 and IVS-I-110 compared to individuals without beta-thalassemia. Methods: One hundred and thirty subjects were studied, including 49 who were heterozygous for beta-thalassemia and 81 controls. Blood samples were subjected to screening tests for hemoglobin. Allele-specific polymerase chain reaction was used to confirm mutations for beta-thalassemia, an analysis of thiobarbituric acid reactive species was used to determine lipid peroxidation, and Trolox equivalent antioxidant capacity evaluations were performed. The heterozygous beta-thalassemia group was also evaluated for serum iron and ferritin status. Results: Thiobarbituric acid reactive species (486.24 ± 119.64 ng/mL and Trolox equivalent antioxidant capacity values (2.23 ± 0.11 mM/L were higher in beta-thalassemia heterozygotes compared to controls (260.86 ± 92.40 ng/mL and 2.12 ± 0.10 mM/L, respectively; p-value < 0.01. Increased thiobarbituric acid reactive species values were observed in subjects with the CD39 mutation compared with those with the IVS-I-110 mutation (529.94 ± 115.60 ng/mL and 453.39 ± 121.10 ng/mL, respectively; p-value = 0.04. However, average Trolox equivalent antioxidant capacity values were similar for both mutations (2.20 ± 0.08 mM/L and 2.23 ± 0.12 mM/L, respectively; p-value = 0.39. There was no influence of serum iron and ferritin levels on thiobarbituric acid reactive species and Trolox equivalent antioxidant capacity values. Conclusion: This study shows an increase of oxidative stress and

    Background Beta thalassemia is a preventable disease. Iran has about 20,000Patients who are homozygote for β-thalassaemia and 3,750,000 carriers. The aim of this study was to determine the prevalence of beta thalassemia minor among men who underwent premarital screening in Quchana city in Khorasan Razavi region of Iran Materials and Methods This research is a descriptive cross-sectional study. From 2010 to 2011, all participants (1000) under marriage coming to health center of Quchan underwent routine mandatory tests. Participants were considered to have beta-thalassemia minor on the condition that hey had a mean corpuscular volume (MCV) 3.5%. Venous blood was taken into an EDTA tube and the complete blood count and red blood cell indices were measured with a Coulter automated cell counter. Electrophoresis was performed on cellulose acetate. Results Mean and SD of hemoglobin, MCV and MCH were 16±2.9, 91±4 and 28.4±2, respectively. Hemoglobin A2 Higher than 3.5 percent was reported as 3.5%.The prevalence of beta-thassemia minor with high hemoglobin A2 and microcytic hypochromic anemia was 3.5% (P-value). Conclusion In countries with high prevalence of hemoglobinopathies, a premarital screening program is helpful for identification and prevention of high-risk marriages. Detecting carrier couples with premarital screening program is an effective way of controlling thalassemia major. PMID:24575266

    In this research, we sought to determine the association between beta-thalassemia trait and ischemic cerebrovascular accident (CVA). In acase-control study, 148 patients with thromboembolic cerebrovascular events were evaluated for the presence of hypertension, diabetes mellitus, hyperlipidemia, and beta-thalassemia trait. A total of 156 age- and sex-matched patients with no cardiac or cerebrovascular diseases, serving as the control group, were also investigated for the above-mentioned risk factors. We found that 6.1% of patients with ischemic CVA and 12.2% of the control group had beta-thalassemia trait (P = .066). In male patients, the negative association between ischemic CVA and presence of beta-thalassemia trait was significant (P = .008). In patients, the prevalence of hypertension was also significantly different between those with and without beta-thalassemia trait (P = .01); those with beta-thalassemia trait had a lower mean blood pressure than those without the trait. beta-Thalassemia trait may have a protective effect against ischemic CVA that might be caused by the lower arterial blood pressure observed in those with this trait.

    Red blood cell transfusion, main therapeutic modality of beta-thalassemia, leads to iron overload which may perturb several metabolic ways. The aim of this paper is to illustrate the uptake abnormalities observed on bone scan of thalassaemic patients and to discuss mechanisms of extraosseous accumulation of the radiopharmaceutical in this pathology. We report a 16-year-old child suffering from beta-thalassemia major undergoing transfusion therapy. A bone scan was indicated to look for osseous infection. This study revealed a little skeletal uptake and abnormal liver, splenic and renal accumulation. A repeat bone scan, performed three weeks later showed a better skeletal uptake which enabled the discovery of focal abnormalities and made the diagnostic easier. The effect of iron overload on radiopharmaceuticals uptake in bone scan is known since 1975. Dissociation of {sup 99m}Tc from the carrier ligand due to the presence of iron excess seems the most plausible hypothesis. Free {sup 99m}Tc can be bound to other tissular substrates which can explain extraosseous uptake. The normally available pool for bone is reduced and then the skeletal uptake decreased. This report limits considerably the sensitivity of the bone scan. A well-led iron chelation and eventually the use of diuretic drug may guarantee a better quality of bone scan images. (authors)

  15. Application of Single Strand Conformational Polymorphism (PCR-SSCP) in Identification of Some Beta-Globin Gene Mutations in A Group of Egyptian Beta-Thalassemia Patients and Carriers

    The present study investigated whether the single-strand conformational polymorphism (SSCP) method could be employed to identify (rather than simply detect) four of the most common beta-globin gene mutations in the Egyptian population: IVS-I-110, IVS-I-6, the IVS-I-1, and Codon 39. Using DNA from 90 beta-thalassemia patients and carriers, by PCR the appropriate 238-bp region of the human beta-globin gene was amplified, the reaction products (Single-stranded DNA) were analyzed by none denaturing polyacrylamide gel electrophoresis, and the bands visualized by silver staining. Single-stranded DNA (ssDNA) fragments showed reproducible pattern of bands that were characteristic of the mutations present. With the use of control samples containing six of the 10 possible combinations of the four beta-globin gene mutations under study, we were able to predict the mutations present in 23 out of 90 (26.4%) of the patients studied. These predictions were confirmed independently by the amplification refractory mutation system (ARMS) method. It is concluded that this non-radioactive PCR-SSCP method can be used to reliably identify mutations in beta-thalassemia patients, provided that suitable controls are available. However, usefulness of this method for determining the genotype of beta-thalassaemic individuals is obviously limited by the great number of controls required. Moreover, the ability to detect mutations by SSCP is in general lower compared to other methods, ARMS, DGGE or DHPLC, which are reported to detect 49.5% to 73% of the mutations present. The SSCP method is nevertheless much easier to employ than other methods and is especially successful for beta-thalassemia carriers. This method would thus be particularly useful for an initial screening of target groups (prenatal diagnosis)

    Full Text Available The rate of erythrocyte alloimmunization in tranfusion-dependent patients can reach 50%, although the frequency of clinically relevant antibodies in transfused patients is not fully known, it is estimated that about 1% of patients are sensitized to each unit of transfused RBCs. The aim of this study is to report the case of  an 11-year-old girl with ?-thalassemia major, chronically transfused, which was detected in pre-transfusion protocol, the presence of two rare anti-erythrocyte antibodies: anti-Colton b (anti-Cob and anti-Lutheran 14 (anti-Lu14. To survey the clinical and laboratory patient history, research records filed in the archives of the university hospital in which the patient is monitored system was performed. The phenotyping erythrocyte in multitransfused patients is essential to decrease the risk of complications due to alloimmunization and estimate the availability of compatible blood. Thus, the report of this case may contribute to increase knowledge about of the real frequency of uncommon anti-erythrocyte antibodies in thalassemic patients.

    Background: Extramedullary hematopoiesis (EMH) occurs in many disorders, including thalassemias and other hemoglobinopathies, and commonly presents in the spleen and liver. We present a case of spinal cord compression in a patient with beta-thalassemia intermedia, and review the literature and available treatment options. Patient and Methods: A 35-year-old black female with beta-thalassemia intermedia presented with a 3-week history of back pain and lower extremity weakness. Neurologic examination was consistent with spinal cord compression, and gadolinium enhanced magnetic resonance imaging (MRI) confirmed this diagnosis. She was given intravenous steroids and radiotherapy was begun in 200 cGy fractions to a total dose of 2000 cGy. Results: At the completion of radiotherapy the patient was ambulatory with mild residual weakness. MRI scans 16 months later showed smaller, but persistent masses, and she remains asymptomatic 5 years from her diagnosis. Conclusion: Recognition of spinal cord EMH requires prompt physical examination and MRI for accurate diagnosis. EMH can be managed with radiation, surgery, transfusions, or a combination of these therapies. Radiation in conservative doses of (750-3500 cGy) is non-invasive, avoids the surgical risks of potentially severe hemorrhage and incomplete resection, and has a high complete remission rate in the majority of patients. Relapse rates are moderate (37.5%), but retreatment provides excellent chance for second remission

    Full Text Available Thalassemia (thal is an autosomal recessive, hereditary, chronic hemolytic anemia due to a partial or complete deficiency in the synthesis of α-globin chains (α-thal or β-globin chains (β-thal that compose the major adult hemoglobin (α2β2. It is caused by one or more mutations in the corresponding genes. The unpaired globin chains are unstable; they precipitate intracellularly, resulting in hemolysis, premature destruction of red blood cell [RBC] precursors in the bone marrow, and a short life-span of mature RBCs in the circulation. The state of anemia is treated by frequent RBC transfusions. This therapy results in the accumulation of iron (iron overload, a condition that is exacerbated by the breakdown products of hemoglobin (heme and iron and the increased iron uptake for the chronic accelerated, but ineffective, RBC production. Iron catalyzes the generation of reactive oxygen species, which in excess are toxic, causing damage to vital organs such as the heart and liver and the endocrine system. Herein, we review recent findings regarding the pathophysiology underlying the major symptoms of β-thal and potential therapeutic modalities for the amelioration of its complications, as well as new modalities that may provide a cure for the disease.

    Full Text Available One of the growth indicators that can be used to assess a child’s developmental growth is through skeletal maturation. Skeletal maturity can be evaluated by using anatomical changes of the cervical vertebral bones observed on the lateral cephalometric radiographs. The purpose of this study was to determine the stage of cervical vertebrae maturation of Hb E β thalassemia patients by comparing the shape changes of the second to fourth cervical vertebrae bodies with a control group. The design of this study was cross sectional. The subjects were children with Hb E β thalassemia aged 9 – 14 years. The results showed that the retarded maturation of the cervical vertebrae in Hb E β thalassemia was not found in the subjects of pre-puberty age (9 – 11 years old, but in those of puberty age (12 – 14 years old.

    Full Text Available Background: Co-inheritance of hemoglobin gene defects is a rare important status that can lead to double heterozygote or homozygote with significant clinical manifestations. Such conditions can be observed in co-inheritance of alpha-thalassemia with beta-thalassemia or hemoglobinopathy. The aim of this study was to evaluate the prevalence of alpha-thalassemia with beta-thalassemia and hemoglobinopathy co-inheritance in a considerable number of Iranian.   Methods: This descriptive study was performed on patients with abnormal hematological findings in favor of alpha-thalassemia, beta-thalassemia or beta-hemoglobinopathies. Patients with low MCV and MCH levels and high HbA2 (>3.5 and those with low MCV and MCH and normal or low HbA2 were candidate for molecular analysis for beta and alpha thalassemia respectively. Abnormal Hb electrophoresis was diagnostic criteria for molecular analysis of beta-hemoglobinopathies.   Results: Study revealed that more than half of the patients with alpha-thalassemia affected simultaneously by beta-thalassemia and about thirty percent inherited beta-hemoglobinopathies. Among patients with beta-thalassemia, HbSCd6 (A-T was the most common mutation and in alpha-thalassemic patients α 3.7 was the commonest mutation.   Conclusion: Relatively high prevalence of co-inheritance of alfa-thalassemia with beta-thalassemia and hemoglobinopathies reflect the necessity of genetic consulting and molecular analysis in diagnosis of such conditions.

    Spinal cord compression due to extramedullary hematopoiesis is a well-described bu rare syndrome encountered in several hematologic disorders, including {beta}-thalassemia. We report a case of a patient with intermediate {beta}-thalassemia and crural paraparesis due to spinal cord compression by a paravertebral extramedullary mass. She was successfully treated with low-dose radiotherapy and transfusions. After splenectomy, she was regularly followed up for over four years without transfusion or recurrence of spinal cord compression. Extramedullary hematopoiesis should be investigated in patients with hematologic disorders and spinal cord symptoms. The rapid recognition and treatment with radiotherapy can dramatically alleviate symptoms. (author)

    Objective: To study the diagnostic strategy of β-thalassemia through retrospective analysis of 3 cases of β-thalassemia. Methods: Three patients were admitted to the Department of Pediatrics, Sun Yat-sen Memorial Hospital of Sun Yat-sen University from January 2014 to June 2015. The clinical manifestations, hemoglobin electrophoresis and gene detection of these patients and their parents were analyzed, diagnostic ideas and key points were discussed when beta thalassemia gene detection did not explain clinical manifestations or hemoglobin electrophoresis. Results: Case 1, boy, 5 years old, was diagnosed as compound heterozygotes of β41-42 and IVS-Ⅱ-654 with hereditary persistence of fetal hemoglobin(HPFH) according to the clinical manifestations of mild anemia, normal size of liver and spleen, 92.8% fetal hemoglobin (HbF) and gene analysis. Case 2, girl, 3 years old, was confirmed the diagnosis of thalassemia intermedia with β41-42 heterozygote compound and ααα anti3.7 heterozygote in accordance with the manifestations of severe anemia, hepatosplenomegaly, 8.6% HbF, 4.1% hemoglobin A 2 (HbA 2 ) and gene analysis. Case 3, girl, 3 years old, with severe anemia, hepatosplenomegaly, 51.2% HbF and 3.7% HbA 2 , was diagnosed as thalassemia major with compound heterozygotes of PolyA (T→C) and β17 by DNA sequencing. Conclusion: The diagnosis of β-thalassemia should be confirmed by clinical manifestations of hemolytic anemia, hemoglobin electrophoresis, gene diagnosis and family survey.

    X-ray scattering from lyophilized proteins or protein-rich samples is characterized by the presence of two characteristic broad peaks at scattering angles equivalent to momentum transfer values of 0.27 and 0.6 nm{sup -1}, respectively. These peaks arise from the interference of coherently scattered photons. Once the conformation of a protein is changed, these two peaks reflect such change with considerable sensitivity. The present work examines the possibility of characterizing the most common cause of hemolytic anaemia in Egypt and many Mediterranean countries; {beta}-thalassemia, from its X-ray scattering profile. This disease emerges from a genetic defect causing reduced rate in the synthesis of one of the globin chains that make up hemoglobin. As a result, structurally abnormal hemoglobin molecules are formed. In order to detect such molecular disorder, hemoglobin samples of {beta}-thalassemia patients are collected, lyophilized and measured using a conventional X-ray diffractometer. Results show significant differences in the X-ray scattering profiles of most of the diseased samples compared to control. The shape of the first scattering peak at 0.27 nm{sup -1}, in addition to the relative intensity of the first to the second scattering peaks, provides the most reliable signs of abnormality in diseased samples. The results are interpreted and confirmed with the aid of Fourier Transform Infrared (FTIR) spectroscopy of normal and thalassemia samples.

    Extramedullary hematopoiesis (EMH) represents tumor-like proliferation of hemopoietic tissue which complicates chronic hemoglobinopathy. Intracranial EMH is an extremely rare occurrence. Magnetic resonance imaging (MRI) offers a precise diagnosis. It is essential to distinguish EMH from other extradural central nervous system tumors, because treatment and prognosis are totally different. Herein, we report the imaging findings of beta-thalassemia in a 13-year-old boy complaining of weakness of left side of the body and gait disturbance; CT and MRI revealed an extradural mass in the right temporoparietal region.

    Beta-thalassemia is an inherited hemoglobin disorder caused by reduced or absent synthesis of the beta globin chains of hemoglobin. This results in variable outcomes ranging from clinically asymptomatic to severe anemia, which then typically requires regular blood transfusion. These regular blood transfusions can result in an iron overload condition. The iron overload condition can lead to iron accumulation in various organs, especially in the heart, leading to iron overload cardiomyopathy, which is the major cause of mortality in patients with thalassemia. In the past decades, there is no doubt that the use of β-thalassemic mice as a study model to investigate the pathophysiology of iron overload cardiomyopathy and the role of various pharmacological interventions, has shed some light in understanding this serious complication and in improving the associated cardiac dysfunction. In this review, the effects that iron overload has on the hearts of β-thalassemic mice under conditions of iron overload as well as the efficacy of pharmacological interventions to combat these adverse effects on the heart are reviewed and discussed. The in-depth understanding of biomolecular alterations in the heart of these iron overload thalassemic mice will help give guidance for more effective therapeutic approaches in the near future. Impact statement Iron overload cardiomyopathy is a major cause of morbidity and mortality in patients with thalassemia. Since investigation of iron overload cardiomyopathy in thalassemia patients has many limitations, a search for an animal model for this condition has been ongoing for decades.

    Heart disease is the main cause of mortality and morbidity in patients with beta thalassemia, rendering its early diagnosis vital. We studied and compared echocardiographic findings in patients with beta thalassemia major, patients with beta thalassemia intermedia, and a control group. Eighty asymptomatic patients with thalassemia major and 22 asymptomatic cases with thalassemia intermedia (8-25 years old) were selected from those referred to Ali Asghar Hospital (Zahedan-Iran) between June 2008 and June 2009. Additionally, 80 healthy individuals within the same age and sex groups were used as controls. All the individuals underwent echocardiography, the data of which were analyzed with the Student t-test. The mean value of the pre-ejection period/ejection time ratio of the left ventricle during systole, the diameter of the posterior wall of the left ventricle during diastole, the left and right isovolumic relaxation times, and the right myocardial performance index in the patients with beta thalassemia major and intermedia increased significantly compared to those of the controls, but the other parameters were similar between the two patient groups. The mean values of the left and right pre-ejection periods, left ventricular end systolic dimension, and left isovolumic contraction time in the patients with thalassemia intermedia increased significantly compared to those of the controls. In the left side, myocardial performance index, left ventricular mass index, isovolumic contraction time, and deceleration time exhibited significant changes between the patients with thalassemia major and those with thalassemia intermedia, whereas all the echocardiographic parameters of the right side were similar between these two groups. The results showed that the systolic and diastolic functions of the right and left sides of the heart would be impaired in patients with thalassemia major and thalassemia intermedia. Consequently, serial echocardiography is suggested in

    Beta-thalassemia is among the most common genetic disorders in the world and in Iran, with widespread occurrence. A cross-sectional study on 648 beta-thalassemia patients in Shiraz, Iran was carried out to determine the demography of beta-thalassemia major in Shiraz city, Fars province, Iran and also the rate of consanguinity and the significance of pre-marriage counseling in decreasing familial marriages and consequently preventing this autosomal recessive genetic disease. All interviewed patients had thalassemia major and their age, sex, and the consanguinity between parents were recorded. 40.6% of beta-thalassemia patients were outcomes of first-cousin marriages. Comparison of the percentages of familial marriages (consanguinity) between parents of beta-thalassemia patients and a sample of normal population, revealed a statistically significant difference (pmarriages among thalassemic families, however, more education and awareness of young women and men about the increased risk of beta-thalassemia after familial marriage through pre-marriage counseling is still necessary.

    Thalassemia intermedia is a type of anemia which has several treatments modalities. We aimed to study the cost effectiveness of two treatments, including blood transfusion and hydroxyurea, in patients with beta-thalassemia intermedia in south of Iran referred to a referral center affiliated to Iran, Shiraz University of Medical Sciences in 2015. This was a cost-effectiveness study which was conducted on 122 patients with beta-thalassemia intermedia. The indicator of effectiveness in this study was the reduction of growth disorder (normal BMI). Data analysis was done using SPSS 21, Excel 2010 and Treeage 2011. Finally, the one-way sensitivity analysis was performed to determine the robustness of the results. The average annual costs of blood transfusion and the use of hydroxyurea in 2015 were 20733.27 purchasing power parity (PPP)$ and 7040.29 PPP$, respectively. The effectiveness of blood transfusion was57.4% while in hydroxyurea group was 60.7%. The results showed that the cost effectiveness of using hydroxyurea was more than that of blood transfusion. Therefore, it is recommended that the use of hydroxyurea in the treatment of patients with beta-thalassemia intermedia would become the first priority, and more basic and supplementary insurance coverage for treating such patients using hydroxyurea should be considered.

    The soluble pool of alpha hemoglobin chains present in blood or bone marrow cells was measured with a new affinity method using a specific probe, beta A hemoglobin chain labeled with [ 3 H]N-ethylmaleimide. This pool of soluble alpha chains was 0.067 ± 0.017% of hemoglobin in blood of normal adult, 0.11 ± 0.03% in heterozygous beta thalassemia and ranged from 0.26 to 1.30% in homozygous beta thalassemia intermedia. This elevated pool of soluble alpha chains observed in human beta thalassemia intermedia decreased 33-fold from a value of 10% of total hemoglobin in bone marrow cells to 0.3% in the most dense red blood cells. The amount of insoluble alpha chains was measured by using the polyacrylamide gel electrophoresis in urea and Triton X-100. In beta thalassemia intermedia the amount of insoluble alpha chains was correlated with the decreased spectrin content of red cell membrane and was associated with a decrease in ankyrin and with other abnormalities of the electrophoretic pattern of membrane proteins. The loss and topology of the reactive thiol groups of membrane proteins was determined by using [ 3 H]N-ethylmaleimide added to membrane ghosts prior to urea and Triton X-100 electrophoresis. Spectrin and ankyrin were the major proteins with the most important decrease of thiol groups

    Beta-thalassemia is an inherited blood disorder. It results from the impaired production of β-globin chains, leading to a relative excess of alpha-globin chains. Clinical severity separates this disease into three main subtypes: β- thalassemia major, β-thalassemia intermedia and β-thalassemia minor, the former two being clinically more significant. Inflammatory processes may play an important role in some of the complications of thalassemia. Adipose tissue is one of the most important endocrine and secretory organs that release adipocytokines like adiponectin, resistin and visfatin. The aim of our study was to analyze adipocytokine concentrations (adiponectin, resistin and visfatin) in different types of β-thalassemia patients and determine any possible correlations with disease severity. We recruited 29 patients who were transfusion-dependent β-thalassemia-major patients, 17 patients with β-thalassemia intermedia, 30 β-thalassemia minor patients. The control group consisted of 30 healthy children. Anthropometric measurements, complete blood count, biochemical parameters, serum concentrations of adiponectin, resistin, visfatin were performed for all subjects. Resistin and visfatin concentrations were significantly higher in β-thalassemia minor patients than in controls. Adiponetin, resistin and visfatin concentrations were significantly higher in both β-thalassemia intermedia and major patients than in controls. The concentrations of adiponectin, resistin and visfatin were significantly higher in both β-thalassemia intermedia and major patients than in β-thalassemia minor patients. There was no significant difference between β-thalassemia intermedia and β-thalassemia major patients for adipocytokines concentrations. We speculate that these adipocytokines may play a role in the development of complications in β-thalassaemia.

    Full Text Available Thalassemia major is a genetic blood disorder that is detected by the symptoms of chronic and severe anemia, enlarged liver and spleen, failure to thrive and bone deformities in particular deformed face and bulging forehead. Due to changes in physical appearance, the disease can influence on other aspects of the patient's life, so the disease can have a strong impact on the mental health of these patients and their families. Previous studies showed that 80% of patients with thalassemia major have at least one psychiatric disorder. The aim of this paper was to review the mental health status of patients with Beta-thalassemia major in Iran.

    Thalassemia is the most common genetic disease worldwide; those with severe disease require lifelong blood transfusion and iron chelation therapy. The definitive cure for thalassemia is allogeneic hematopoietic stem cell transplantation, which is limited due to lack of HLA-matched donors and the risk of post-transplant complications. Induced pluripotent stem cell (iPSC) technology offers prospects for autologous cell-based therapy which could avoid the immunological problems. We now report genetic correction of the beta hemoglobin (HBB) gene in iPSCs derived from a patient with a double heterozygote for hemoglobin E and β-thalassemia (HbE/β-thalassemia), the most common thalassemia syndrome in Thailand and Southeast Asia. We used the CRISPR/Cas9 system to target the hemoglobin E mutation from one allele of the HBB gene by homology-directed repair with a single-stranded DNA oligonucleotide template. DNA sequences of the corrected iPSCs were validated by Sanger sequencing. The corrected clones were differentiated into hematopoietic progenitor and erythroid cells to confirm their multilineage differentiation potential and hemoglobin expression. The hemoglobin E mutation of HbE/β-thalassemia iPSCs was seamlessly corrected by the CRISPR/Cas9 system. The corrected clones were differentiated into hematopoietic progenitor cells under feeder-free and OP9 coculture systems. These progenitor cells were further expanded in erythroid liquid culture system and developed into erythroid cells that expressed mature HBB gene and HBB protein. Our study provides a strategy to correct hemoglobin E mutation in one step and these corrected iPSCs can be differentiated into hematopoietic stem cells to be used for autologous transplantation in patients with HbE/β-thalassemia in the future.

    Beta-thalassemia is one of the most common hereditary disorders in Iran. The prenatal diagnosis of beta-thalassemia is part of a control program in our country and it began 13 years ago. During the past 8 years the number of procedures has increased significantly as also the legal abortions. This is the first report made on the CVS program in Iran. One thousand six hundred and sixty-one cases of transabdominal Chorionic Villus Sampling (CVS) have been retrospectively evaluated. Among them 1381 cases had inclusion criteria. CVS results, complications and fetal loss rate were evaluated. The distributions of the population at risk were divided between eight regions that have been proposed for beta-thalassemia mapping previously. The mean age of the patients was 26.2 +/- 5.2 years with mean gestational age of 11.4 +/- 1.4 weeks. CVS was successful in all the patients (100%) although 1% required a second procedure. Post CVS fetal loss was 1.45%. Other minor complications were bleeding or spotting (1.81%), amniotic fluid leak (0.5%), small sub-chorionic hematoma (0.58%), severe abdominal pain (0.6%) and severe vasovagal reaction (0.14%). Late complications were seen in 0.21% (oligohydraminos). Approximately 2/3 of the patients were referred from three regions of the country, North (26.8%), South West (22.4%), Central (19.5%) and the remainder (31.3%) were from the other five regions. CVS is a safe and effective method for prenatal diagnosis of beta-thalassemia in countries with a high prevalence as in Iran. The overall complication rate is quite low and acceptable. Fortunately the recent acceptance of legal abortion with respect to Muslim rules has increased the effectiveness of the procedure and made great advances in its application in Iran. Correspondingly, social knowledge has also improved but still there is a gap between the population at risk and the required prenatal diagnosis laboratories and sampling centers. 2006 John Wiley & Sons, Ltd.

    Full Text Available Background: Both insulin deficiency and resistance are reported in patients with β-thalassemia major (BTM. The use of continuous blood glucose monitoring (CGM, among the different methods for early detection of glycemic abnormalities, has not been studied thoroughly in these adolescents. Materials and Methods: To assess the oralglucose tolerance (OGT and 72-h continuous glucose concentration by the continuous glucose monitoring system (CGMS and calculate homeostatic model assessment (HOMA, and the quantitative insulin sensitivity check index (QUICKI was conducted in 16 adolescents with BTM who were receiving regular blood transfusions every 2-4 weeks and iron-chelation therapy since early childhood. Results: Sixteen adolescents with BTM (age: 19.75 ± 3 years were investigated. Using OGTT, (25% had impaired fasting blood (plasma glucose concentration (BG (>5.6 mmol/L. 2-h after the glucose load, one of them had BG = 16.2 mmol/L (diabetic and two had impaired glucose tolerance (IGT (BG > 7.8 and 11.1 mmol/L and 9 with IGT (56%. HOMA and QUICKI revealed levels 0.33 (0.36 ± 0.03, respectively, ruling out significant insulin resistance in these adolescents. There was a significant negative correlation between the β-cell function (B% on one hand and the fasting and the 2-h BG (r=−0.6, and − 0.48, P < 0.01, respectively on the other hand.

    High-resolution melting (HRM) analysis is a rapid mutation analysis which assesses the pattern of reduction of fluorescence signal after subjecting the amplified PCR product with saturated fluorescence dye to an increasing temperature. We used HRM analysis for prenatal diagnosis of beta-thalassemia disease in northern Thailand. Five PCR-HRM protocols were used to detect point mutations in five different segments of the beta-globin gene, and one protocol to detect the 3.4 kb beta-globin deletion. We sought to characterize the mutations in carriers and to enable prenatal diagnosis in 126 couples at risk of having a fetus with beta-thalassemia disease. The protocols identified 18 common mutations causing beta-thalassemia, including the rare codon 132 (A-T) mutation. Each mutation showed a specific HRM pattern and all results were in concordance with those from direct DNA sequencing or gap-PCR methods. In cases of beta-thalassemia disease resulting from homozygosity for a mutation or compound heterozygosity for two mutations on the same amplified segment, the HRM patterns were different to those of a single mutation and were specific for each combination. HRM analysis is a simple and useful method for mutation identification in beta-thalassemia carriers and prenatal diagnosis of beta-thalassemia in northern Thailand.

    We describe hematological and molecular characterization of a Thai female who had Southeast Asian ovalocytosis (SAO) associated with beta+-thalassemia trait. The proband had mild microcytosis with Hb 12.9 g/dl, Hct 35.8%, MCV 74.4 fl, MCH 26.8 pg, MCHC 36.0 g/dl, and elevated Hb A2 (5.6%), characteristics of beta-thalassemia trait. Peripheral blood film examination revealed prominent ovalocytosis. However, a one-tube osmotic fragility (OF) test commonly used for thalassemia screening was negative and a normal OF curve was observed. Further polymerase chain reaction (PCR) analyses identified the beta(-28A-G) mutation in the beta-globin gene and a 27 bp deletion in erythrocyte band 3 protein gene, indicating a genetically compound heterozygote. Hematological data of the proband was comparatively presented with those of eight female and 15 male carriers of pure beta-thalassemia with the same mutation. The finding demonstrates that although the association of the SAO and beta-thalassemia does not produce a more severe clinical picture, this could lead to a mis-screening of beta-thalassemia using an OF test as a primary screening test. Additional blood film examination followed by PCR could help in the detection of this unusual genetic interaction in the region. (c) 2006 Wiley-Liss, Inc.

    Full Text Available Objective: Iron deficiency anemia (IDA and beta-thalassemia trait (ß-TT are the most common forms of microcytic anemia. This study was conducted to compare the validity of various discrimination indices in differentiating β-TT from IDA by calculating their sensitivity, specificity and Youden's index.Methods: Totally 323 subjects (173 children and 150 adults with microcytic anemia were involved in this study. We calculated 10 discrimination indices in all patients with IDA and β-TT. We divided the patients into two different groups as younger or older than 10 years. Results: None of the indices showed sensitivity and specificity of 100% in the patients older than 10 years, and in the patients younger than 10 years, only Shine & Lal index showed sensitivity close to 90% and specificity of 100%. The most accurate discriminative index for patients younger than 10 years was Shine & Lal and for those older than 10 years it was RDW index. According to Youden's index, Shine & Lal and RBC count showed the greatest diagnostic value in patients younger than 10 years and RDW and RBC count indices in those older than 10 years. Conclusion: None of the indices was completely sensitive and specific in differentiation between β-TT and IDA. Mean and median mean cell Hb density (MCHD were very close to normal values in both IDA and β-TT patients, but in the case of mean density of Hb/liter (MDHL, we found that the mean and median were significantly higher than normal values in β-TT and lower than normal values in IDA patients. In our study, Youden's index of RBC and Shine & Lal were the highest and most reliable indices in differentiating β-TT from IDA in the patients younger than 10 years. For patients older than 10 years, the most reliable discrimination indices were RBC and RDW.

    This study was planned to explore the self-concept, behavioral, and parental attitudes of the children with beta-thalassemia major, and the factors that affect them. The study was undertaken between January and June 2004 at the Hacettepe University Ihsan Doğramaci Children's Hospital, Pediatric Hematology Unit, Ankara and 43 voluntary children with beta-thalassemia major on regular blood transfusion and iron chelation treatment between the ages of 5.0 and 18.0 years were included into the study. Age, sex, birth order, school performance, hemoglobin value, serum ferritin levels, associated illness, splenectomy status, presence of thalassemic sibling or relatives, death of thalassemic relatives, place of residence, maternal and paternal education were recorded. Parental Attitude Research Instrument, Piers-Harris Self-Concept Scale, and Child Behavior Checklist were applied. Higher educated mothers have lower overprotection (P=0.009), parental discordance (P=0.044), and discipline scores (P=0.002) than lower educated mothers. In cases with death of thalassemic relatives, democratic/equality attitude scores were decreased (P=0.034). With stepwise multiple linear regression analysis, splenectomy, good school achievement, absence of death of thalassemic relatives, and serum ferritin levels were found to increase Piers-Harris Self-Concept Scale; however, total behavior problem score was found to decrease with increasing age, splenectomy and decreasing overprotection subscale of Parental Attitude Research Instrument scores. The self-esteem and behavior problems of children with thalassemia depended not only on the variables related exclusively to the child (age, school achievement) and the illness-associated conditions (splenectomy, serum ferritin levels) but also on the parental attitude (overprotection).

    The Al-Hassa area is one of the regions in Saudi Arabia where hemoglobinopathies are prevalent. The Saudi Ministry of Health designed a protocol for premarital testing after the royal decree in December 2003. The protocol was implemented in a February 2004 order. The aim of this study was to determine the prevalence of beta-thalassemia trait among subjects coming for premarital screening in the Al-Hassa area. From February 2004 to November 2004, healthy subjects coming to six marriages consultation centers in the Al-Hassa area underwent routine mandatory tests. Subjects were considered to have beta-thalassemia trait if they had a mean corpuscular volume (MCV), 80 fL and/or a mean corpuscular hemoglobin (MCH) 3.2%. Venous blood was taken into ETDA tube and the complete blood count and red blood cell indices were measured by a Coulter automated cell counter on the same day of hemoglobin collection. Electrophoresis was done on cellulose acetate. All Saudi participants (n=8918), including 4218 (47.3%) males and 4700 (52.7%) females were screened. The prevalence of beta-thalassemia trait with high hemoglobin A2 and microcytic hypochromic anemia was 3.4% (307/8918). In countries with a high prelevance of hemoglobinopathies, a premarital screening program is helpful for identification and prevention of high-risk marriages. With a 3.4% prevalence of beta-thalassemia trait in premarital couples, future comprehensive programs are needed to know the actual prevalence of beta-thalassemia in Al-Hassa. (author)

    Objective: To compare the validity of a new index (Hb X RDW X 100/ (RBC)/sup 2/ X MCHC) with twelve discriminating functions (DFs) to differentiate iron deficiency anemia (IDA) and beta-thalassemia trait (beta-TT). Methodology: A total of 823 patients (317 IDA and 506 beta-TT) aged 15 to 35 year old were enrolled in this study. The diagnostic sensitivity, specificity and other validity parameters were calculated to assess the diagnostic reliability of the novel index [Keikhaei index (KI)] vis-a-vis the other published DFs [Mentzer Index (MI), Green and King Index (G and KI), red cell distribution width index (RDWI), England and Fraser Index (E and FI), Bessman and Feinstein index (B and FI), Telmissani et al index (TI), Srivastava and Bevington index (S and BI), Shine and Lal index (S and LI), Ricerca et al index (RI), Ehsani et al index (EI), Sirdah et al index (SI), and Red Blood Cell Count(RBC)] were calculated in all patients. Results: All thirteen DFs did not have the sensitivity and specificity of 100%. The KI, RDWI, Gand KI and E and FI showed the most sensitivity and specificity for both IDA and TT; moreover, the lowest reliable indices belonged to B and FI, SandLI and RI. Conclusion: According to Youden's index (YI), DFs in the order of highest to lowest were KI > G and KI > RDWI > E and FI > RBC> M I> EI > TI > SI > S and BI > RI> SandLI >B and FI. (author)

    Full Text Available Abstract Background Beta thalassemia is the most frequent genetic disorder of haemoglobin synthesis in Pakistan. Recurrent transfusions lead to iron-overload manifested by increased serum Ferritin levels, for which chelation therapy is required. Findings The study was conducted in the Pediatric Emergency unit of Civil Hospital Karachi after ethical approval by the Institutional Review Board of Dow University of Health Sciences. Seventy nine cases of beta thalassemia major were included after a written consent. The care takers were interviewed for the socio-demographic variables and the use of Desferrioxamine therapy, after which a blood sample was drawn to assess the serum Ferritin level. SPSS 15.0 was employed for data entry and analysis. Of the seventy-nine patients included in the study, 46 (58.2% were males while 33 (41.8% were females. The mean age was 10.8 (± 4.5 years with the dominant age group (46.2% being 10 to 14 years. In 62 (78.8% cases, the care taker education was below the tenth grade. The mean serum Ferritin level in our study were 4236.5 ng/ml and showed a directly proportional relationship with age. Desferrioxamine was used by patients in 46 (58.2% cases with monthly house hold income significant factor to the use of therapy. Conclusions The mean serum Ferritin levels are approximately ten times higher than the normal recommended levels for normal individuals, with two-fifths of the patients not receiving iron chelation therapy at all. Use of iron chelation therapy and titrating the dose according to the need can significantly lower the iron load reducing the risk of iron-overload related complications leading to a better quality of life and improving survival in Pakistani beta thalassemia major patients.

    The objective of this study was to identify factors involved in the success of 2 well-established population-based carrier screening programs - Tay-Sachs disease (TSD) in Ashkenazi Jews and beta-thalassemia in Sardinia and Cyprus - and to assess the potential for success of a population-based cystic fibrosis (CF) carrier screening strategy using these factors. We performed a literature review and key informant interviews. Factors involved in the success of TSD and beta-thalassemia carrier screening programs include disease characteristics (well-defined population at risk, severe disease with predictable course, availability of effective treatment), test characteristics (high sensitivity, straightforward interpretation of results), and community characteristics (involvement of community, support of families and advocacy groups, consensus in favor of avoiding affected births). Current CF screening strategies include few of the factors listed above. Unlike TSD and beta-thalassemia, the purpose of current CF carrier screening strategies is informed reproductive decision-making, without an explicit goal of reducing disease incidence. When compared to TSD and beta-thalassemia, CF is a less favorable candidate for population-based carrier screening. Because of its different purpose, CF carrier screening will require different measures of success than those used for TSD and beta-thalassemia carrier screening, and a consensus on the value or success of CF carrier screening may be difficult to achieve.

  14. Double heterozygocity for hemoglobin C and beta thalassemia dominant: A rare case of thalassemia intermedia

    Alexandra Agapidou

    2018-01-01

    Full Text Available Beta thalassemia dominant results from mutations in the β globin chain gene resulting in the production of elongated, highly unstable beta globin chains. Several such mutations have been described and in a heterozygous state they may confer a phenotype more severe than that of β thalassemia trait and lead to a clinical syndrome of thalassemia intermedia and its associated complications such as extramedullary hemopoiesis, bone disease, endocrinopathies and iron overload even in the absence of transfusion. In this report we present a case of double heterozygocity for HbC and β thalassemia dominant leading to a series of complications that were treated successfully once the correct diagnosis was made.

    For beta thalassemia control program in pregnancy, mass screening of the carrier state by determination of the hemoglobin (Hb) A 2 and Hb E proportions and mutation analysis is a preferred method for making prenatal diagnoses. Q Sepharose micro-column chromatography, developed for the determination of Hb A 2 and Hb E for screening purposes, was compared with high performance liquid chromatography (HPLC) to ascertain its relative accuracy and reliability. Results using Q Sepharose micro-column chromatography in 350 blood specimens, including 50 samples genetically proven to be beta thalassemia heterozygotes, were compared to HPLC for validation. An additional study was conducted to test a clinical application on a large-scale survey for beta thalassemia in 1581 pregnant women and their spouses. The mean (±SD) Hb A 2 proportions in the normal and genetically proven beta thalassemia heterozygotes were 2.70±0.40% and 6.30±1.23%, respectively, as determined by Q-Sepharose micro-column chromatography, and 2.65±0.31% and 5.37±0.96%, respectively, as determined by HPLC. The mean Hb E proportions in the Hb E heterozygotes were 23.25±4.13% and 24.72±3.5% as determined by Q Sepharose micro-column chromatography and HPLC, respectively. In the large-scale survey for beta thalassemia, 23 at risk couples were detected. Seven affected fetuses were identified by prenatal diagnosis. Q Sepharose micro-column chromatography was found to be reliable, reproducible and well-suited for large-scale surveys. Additionally, by being reusable and convenient, this simple and economical chromatography method may be an alternative means to screen for beta thalassemia and Hb E carriers in the mass population.

    Full Text Available Anemia has an important role in exercise performance. However, the direct link between rapid changes of hemoglobin and exercise performance is still unknown.To find out more on this topic, we studied 18 beta-thalassemia major patients free of relevant cardiac dysfunction (age 33.5±7.2 years,males = 10. Patients performed a maximal cardiopulmolmonary exercise test (cycloergometer, personalized ramp protocol, breath-by-breath measurements of expired gases before and the day after blood transfusion (500 cc of red cell concentrates. After blood transfusion, hemoglobin increased from 10.5±0.8 g/dL to 12.1±1.2 (p<0.001, peak VO2 from 1408 to 1546mL/min (p<0.05, and VO2 at anaerobic threshold from 965 to 1024mL/min (p<0.05. No major changes were observed as regards heart and respiratory rates either at peak exercise or at anaerobic threshold. Similarly, no relevant changes were observed in ventilation efficiency, as evaluated by the ventilation vs. carbon dioxide production relationship, or in O2 delivery to the periphery as analyzed by the VO2 vs. workload relationship. The relationship between hemoglobin and VO2 changes showed, for each g/dL of hemoglobin increase, a VO2 increase = 82.5 mL/min and 35 mL/min, at peak exercise and at anaerobic threshold, respectively. In beta-thalassemia major patients, an acute albeit partial anemia correction by blood transfusion determinates a relevant increase of exercise performance, observed both at peak exercise and at anaerobic threshold.

    Isoelectric focusing of the hemolysate prepared from a two-year-old American black boy with microcytic hypochromia showed the presence of a high percentage (63.3%) of such Hb variant as Hb S, while the levels of Hb A, Hb F and Hb A2 were 20.0%, 12.7%, and 4.0%, respectively. The ratio of the non-alpha-chain to the alpha-chain of the biosynthesized globin chains was 0.49. The variant was identified as Hb S by amino acid analysis of the abnormal peptide (beta T-1) and digestion of DNA amplified by the polymerase chain reaction with enzyme Eco 81 I. This was further confirmed by DNA sequencing. DNA sequencing of a beta-gene without the beta s-mutation revealed a nucleotide change of T to C in the polyadenylation signal sequence AATAAA 3' to the beta-gene, resulting in beta(+)-thalassemia. These results are consistent with the existence of a beta s-gene and a beta(+)-thalassemia gene in trans.

    Full Text Available As the life expectancy of β-thalassemia patients has markedly improved over the last decade, several new complications are being recognized. The presence of a high incidence of thromboembolic events, mainly in thalassemia intermedia patients, has led to the identification of a hypercoagulable state in thalassemia. In this review, the molecular and cellular mechanisms leading to hypercoagulability in thalassemia are highlighted, and the current clinical experience is summarized. Recommendations for thrombosis prophylaxis are also discussed.

    Full Text Available Thalassemia intermedia is a genetically diverse group of diseases that is the result of an imbalance in the production of the alpha and beta chains with ensuing chronic hemolysis, ineffective erythropoiesis, and iron overload.Resulting complications include bone changes, hypercoagulability, and end-organ damage due to iron overload. This decade has witnessed major breakthroughs in the management of thalassemia. In this article, we examine these novelties in therapy including iron chelation therapy, stem cell transplant, and gene therapy.Iron chelation therapy has been revolutionized with the advent of deferasirox, a once-daily oral iron chelator, that has been shown to be safe and efficacious.Gene therapy was also at the core of this revolution with the discovery of novel gene elements and viral vectors allowing for better control and improved outcomes.

    The study aims at describing the MR features of pancreas in beta-thalassemia major, investigating the relations between MR findings and glucose disturbances and between hepatic and pancreatic siderosis. Signal intensity ratios of the pancreas and liver to right paraspinous muscle (P/M, L/M) were retrospectively assessed on abdominal MR imaging studies of 31 transfusion-dependent patients with beta-thalassemia major undergoing quantification of hepatic siderosis and 10 healthy controls, using T1- (120/4/90), intermediate in and out of phase - (120/2.7, 4/20), and T2*-(120/15/20) weighted GRE sequences. Using the signal drop of the liver and pancreas on opposed phase images, we recorded serum ferritin and results of oral glucose tolerance test (OGTT). Decreased L/M and P/M on at least the T2* sequence were noticed in 31/31 and 30/31 patients, respectively, but no correlation between P/M and L/M was found. Patients with pathologic OGTT displayed a higher degree of hepatic siderosis (p < 0.04) and signal drop of pancreas on opposed phase imaging (p < 0.025), implying fatty replacement of pancreas. P/M was neither correlated with glucose disturbances nor serum ferritin. Iron deposition in the pancreas cannot be predicted by the degree of hepatic siderosis in beta-thalassemia major. Fatty replacement of the pancreas is common and may be associated with glucose disturbances. (orig.)

    Full Text Available Background : Children suffering from beta-thalassemia major require repeated blood transfusions which may be associated with dangers like iron overload and contraction of infections such as HIV, HCV, and HBsAg which ultimately curtail their life span. On the other hand, inadequate transfusions lead to severe anemia and general fatigue and debility. Materials and Methods: Data were obtained from 142 beta-thalassemia major patients aged 3 years or more receiving regular blood transfusions at a transfusion centre in Western India from 1 April 2009 to 30 June 2009. The clinical data and laboratory results were subsequently analyzed. Results: Of the 142 patients, 76 (53.5% were undertransfused (mean Hb <10 gm%. 96 (67% of the patients were taking some form of chelation therapy but out of them only 2 (2% were adequately chelated (S. ferritin <1000 ng/ml. 5 (3.5% of the patients were known diabetics on insulin therapy. 103 (72% of the patients were retarded in terms of growth. The prevalence of transfusion-transmitted infections (TTIs such as HCV, HIV, and HBsAg was respectively 45%, 2%, and 2%, with the prevalence of HCV being significantly more than the general population. The HCV prevalence showed positive correlation with the age of the patients and with the total no of blood transfusions received. As many as 15% (6 out of 40 children who were born on or after 2002 were HCV positive despite the blood they received being subjected to screening for HCV. Conclusions: The study suggests the need to step up the transfusions to achieve hemoglobin goal of 10 gm% (as per the moderate transfusion regimen and also to institute urgent and effective chelation measures with the aim of keeping serum ferritin levels below 1000 ng/ml to avoid the systemic effects of iron overload. In addition, strict monitoring of the children for endocrinopathy and other systemic effects of iron overload should be done. Rigid implementation of quality control measures for the

    Full Text Available Beta-thalassemia major (TM is among prevalent hereditary disorders imposing high expenses on health-care system worldwide. The patient’s survival is dependent on lifetime blood transfusion which leads to iron overload and its toxicity on various organs including endocrine glands. This article provides an overview of  endocrine disorders in beta-TM patients. This single center investigation enrolled 28 beta-TM patients (16 males, 12 females  regularly transfused with packed red cell since early years of life. For each patient were determined: age, sex, number of transfusions received, history of splenectomy and anthropometric parameters. Evaluation for hormonal status including growth, gonadal, thyroid, adrenal cortex, and parathyroid glands was done for all patients. Dual energy X-ray absorptiometry was used to diagnose osteoporosis. Assessment of iron overload status was performed by measuring the serum ferritin concentration and the results of magnetic resonance imaging T2*. Growth retardation was found in 16 of the 28 studied patients (57 %.Thirteen among them had delayed puberty. Spontaneous puberty was achieved in 16 cases. Growth hormone (GH deficiency was found in 10 cases (35 %. Seventeen among the studied patients (60 % developed disorders of glucose homeostasis. Subclinical hypothyroidism was found in six patients (21 %. Intensive chelation therapy had allowed the reversibility of this complication in five cases. Adrenal Insufficiency was found in 9 cases (32%. Hypoparathyroidism has occurred in one case. Ten of the 28 studied patients had osteoporosis (35%. Twenty-three of the 28 studied patients (82% had at least one endocrine complication.

    Beta thalassaemia minor is a common genetic disorder without any characteristic symptoms except mild anemia. It is found to be associated with some cardiovascular risk factors such as insulin resistance and diabetes mellitus. The renal resistive index (RRI) is a measure of renal arterial resistance to blood flow. The aim of this study was to evaluate the renal resistive index in subjects with beta thalassaemia minor (BTM). A total of 253 subjects were included in this cross-sectional study. The study group consisted of 148 subjects with BTM and the control group consisted of 105 healthy subjects. Beta thalassaemia minor was diagnosed by complete blood count and hemoglobin electrophoresis. Blood pressure measurement and biochemical tests were performed. Renal resistive index of all subjects was measured using renal Doppler ultrasonography. Subjects with beta thalassemia minor had lower renal resistive indices compared to healthy subjects (0.58 ± 0.04 vs. 0.60 ± 0.06, p = 0.0016). Additionally, the RRI levels of subjects with BTM were correlated with systolic blood pressure (p = 0.017, r = 0.194). In this study, lower renal resistive index was found in subjects with BTM. This may be associated with decreased vascular resistance and blood viscosity in these subjects. ©2018The Author(s). Published by S. Karger AG, Basel.

    Full Text Available A hemoglobina C (Hb C é originária do oeste da África e é detectada por migração lenta na eletroforese alcalina em acetato de celulose. Consiste na mutação do gene da globina beta no códon 6 (GAG-AAG, resultando na substituição do sexto aminoácido da cadeia beta da hemoglobina humana, o ácido glutâmico, pelo aminoácido lisina. A cromatografia de alto desempenho (HPLC separa completamente as frações C e A2, permitindo caracterizar a presença da interação com talassemia beta. Esta entidade (Hb CC, em homozigoze é considerada benigna em relação à doença falciforme, já que a falcização não faz parte de sua fisiopatologia. A raridade do diagnóstico C homozigoto e C talassemia beta nos pacientes portadores de hemoglobinopatias nos alertou para a necessidade de se conhecer melhor e estudar aspectos clínicos e hematológicos dos casos dessa mutação em homozigose e na interação com a talassemia beta no ambulatório de anemias do Centro Regional de Hematologia e Hemoterapia de Ribeirão Preto, SP, Brasil.Hemoglobin C (Hb C originated in the west of Africa and is detected by alkaline electrophoresis by slow migration in cellulose acetate. It consists of a mutation of the beta globin gene in codon 6 (GAG-AAG, resulting in a substitution of glutamic acid, the sixth amino acid of the beta string of the human hemoglobin, for lysine. High performance chromatography (HPLC separates the C and A2 fractions completely, allowing the characterization of the presence of interactions with thalassemia beta. This entity (Hb CC is considered benign in respect to sickle cell disease, as sickle cells are not part of its physiopathology. The rarity of the diagnosis of homozygous C and beta thalassemia in patients with hemoglobinopathies showed the necessity of studying clinical and hematologic aspects of the cases of this mutation in homozygosis carriers and the interaction with beta thalassemia in the anemias clinic of the Regional Blood

    Hemoglobin Vicksburg was discovered in a 6-year-old Black boy who had been anemic since infancy. Examination of his hemolysate revealed 87.5% Hb F, 2.4% Hb A2, and 7.6% Hb Vicksburg, which had the electrophoretic and chromatographic properties of Hb A. Structural analysis of Hb Vicksburg demonstrated a deletion of leucine at beta 75(E19), a new variant. Hb Vicksburg was neither unstable nor subject to posttranslational degradation. The alpha/non-alpha biosynthetic ratio was 2.6. Because the proband appeared to be a mixed heterozygote for Hb Vicksburg and beta 0-thalassemia, Hb Vicksburg should have comprised the major portion of the hemolysate. Thus, Hb Vicksburg was synthesized at a rate considerably lower than would be expected on the basis of gene dosage. There was no reason to suspect abnormal translation of beta Vicksburg mRNA; in individuals with Hb St. Antoine (beta 74 and beta 75 deleted), the abnormal hemoglobin comprised 25% of the hemolysate in the simple heterozygote yet was unstable. Deletion of beta 75, therefore, would not in itself appear to lead to diminished synthesis. There was a profound deficit of beta Vicksburg mRNA when measured by liquid hybridization analysis with beta cDNA. The most plausible explanation for the low output of Hb Vicksburg is that a mutation for beta +-thalassemia is present in cis to the structural mutation.

    Paraoxonase-1 (PON1) deficiency is related to increased susceptibility to low density lipoprotein oxidation and development of atherosclerosis. The aim of this study was to investigate paraoxonase and arylesterase activities along with oxidative status parameters, and to find out if there is any increased susceptibility to atherogenesis, which might be reflected with increased oxidative stress and decreased serum PON1 activity in beta-thalassemia minor (BTM) subjects. Thirty-two subjects with BTM and 28 healthy subjects as control were enrolled in the study. Serum paraoxonase and arylesterase activities, lipid hydroperoxide (LOOH) levels, total antioxidant capacity (TAC), total oxidant status (TOS) and oxidative stress index (OSI) were determined. Serum TAC, paraoxonase and arylesterase activities were significantly lower in BTM subjects than controls (for all p<0.001), while TOS, LOOH levels and OSI were significantly higher (p<0.001, p<0.05 and p<0.001; respectively). In BTM subjects, OSI, TOS, LOOH levels and TAC were significantly correlated with serum paraoxonase (r=-0.245, p<0.05; r=-0.231, p<0.05; r=-0.264, p<0.05 and, r=0.342, p<0.05, respectively) and arylesterase activities (r=-0.332, p<0.05, r=-0.308, p<0.05; r=-0.320, p<0.05 and r=0.443, p<0.05). Additionally, hemoglobin level was also correlated with serum paraoxonase (r=0.501, p<0.001) and arylesterase activities (r=0.501, p<0.001), TAC (r=0.402, p<0.05), TOS (r=-0.274, p<0.05) and OSI (r=-0.352, p<0.05). Oxidative stress is increased, while serum PON1 activity is decreased in BTM subjects. Decrease in PON1 activity seems to be associated with both the degree of oxidative stress and anemia. BTM subjects may be more prone to development of atherogenesis due to low serum PON1 activity.

    To investigate the gene frequencies and mutation patterns of alpha thalassemia (alpha-thal) and beta thalassemia (beta-thal) in Liuzhou city of Guangxi Zhuang Autonomous Region. Cluster sampling was used. A total of 1 028 of umbilical blood samples were collected for a prevalence study of alpha-thal and a total of 1 312 healthy young people when receiving pre-marriage consultation were recruited for a beta-thal prevalence survey. Individuals live in city or town area of Liuzhou. A complete blood count as well as hemoglobin electrophoresis analysis were done in all of samples for phenotyping of alpha and beta-thals. Those with Hb Bart's for alpha-thal indicator and those with both microcytosis (MCV /=4.0%) for beta-thal were further studied by DNA analysis. PCR-based methodologies were used to characterize the mutation contributions of alpha and beta-thals. All the subjects were tested for the state of carrying beta-thala alleles for evaluating the situation of the compound heterozygotes of alpha-thal with beta-thal. Of 1 028 random samples of umbilical blood screened, 112 of subjects were defined to be the gene carriers of alpha-thal. The alpha-thal carrier rate was as high as 11.19% including 3 compound heterozygotes. Five well-known types of alpha-thal alleles were detected with gene contributions of 37.4% (--(SEA) deletion), 31.3% (-alpha(3.7) deletion), 17.4% (-alpha(4.2) deletion), 12.1% (alpha(CS)alpha mutation), and 0.9% (alpha(QS)alpha mutation), successively. Of the 1 312 adult specimens studied, 89 with beta-thal including 14 of the compound higher Hb F subjects were detected. All of the 89 phenotypic beta-thal carriers had the mutations in the beta-globin gene, making the overall prevalence 6.78%. The commonly seen three mutations, beta CD41 - 42 (-CTTT) frameshift, beta CD17 (T-A) nonsense mutation and beta-28 (A-G) promoter variation were accounted for 90% of the beta-thal alleles in Liuzhou. Of these beta-thal subjects, 16 (accounting for 18%) were

    Full Text Available Purpose: To study the ocular manifestations in multiple transfused beta-thalassemia major patients and assess the ocular side-effects of iron chelating agents. Materials and Methods: In this prospective observational study, 45 multiple transfused beta-thalassemia major children between six months and 21 years of age were enrolled and assigned groups according to the treatment regimens suggested. Group A received only blood transfusions, Group B blood transfusions with subcutaneous desferrioxamine, Group C blood transfusions with desferrioxamine and oral deferriprone and Group D blood transfusions with deferriprone. Ocular status at the time of enrolment was documented. Subjects were observed quarterly for one year for changes in ocular status arising due to the disease process and due to iron chelation therapy. Children with hemoglobinopathies other than beta-thalassemia major, congenital ocular anomalies and anemia due to other causes were excluded. Results: Ocular involvement was observed in 58% of patients. Lenticular opacities were the most common ocular finding (44%, followed by decreased visual acuity (33%. An increased occurrence of ocular changes was observed with increase of serum ferritin and serum iron levels as well as with higher number of blood transfusions received. Desferrioxamine seemed to have a protective influence on retinal pigment epithelium (RPE mottling. Occurrence of lenticular opacities and RPE degeneration correlated positively with use of desferrioxamine and deferriprone respectively. Follow-up of patients for one year did not reveal any change in ocular status. Conclusion: Regular ocular examinations can aid in preventing, delaying or ameliorating the ocular complications of thalassemia.

    Full Text Available Variations in the phenotypic expression of heterozygous beta thalassemia reflect the formation of different populations. To better understand the profile of heterozygous beta-thalassemia of the Brazilian population, we aimed at establishing parameters to direct the diagnosis of carriers and calculate the frequency from information stored in an electronic database. Using a Data Mining tool, we evaluated information on 10,960 blood samples deposited in a relational database. Over the years, improved diagnostic technology has facilitated the elucidation of suspected beta thalassemia heterozygote cases with an average frequency of 3.5% of referred cases. We also found that the Brazilian beta thalassemia trait has classic increases of Hb A2 and Hb F (60%, mainly caused by mutations in beta zero thalassemia, especially in the southeast of the country.

    The generation of beta-thalassemia (β-Thal) patient-specific induced pluripotent stem cells (iPSCs), subsequent homologous recombination-based gene correction of disease-causing mutations/deletions in the β-globin gene (HBB), and their derived hematopoietic stem cell (HSC) transplantation offers an ideal therapeutic solution for treating this disease. However, the hematopoietic differentiation efficiency of gene-corrected β-Thal iPSCs has not been well evaluated in the previous studies. In this study, we used the latest gene-editing tool, clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated 9 (Cas9), to correct β-Thal iPSCs; gene-corrected cells exhibit normal karyotypes and full pluripotency as human embryonic stem cells (hESCs) showed no off-targeting effects. Then, we evaluated the differentiation efficiency of the gene-corrected β-Thal iPSCs. We found that during hematopoietic differentiation, gene-corrected β-Thal iPSCs showed an increased embryoid body ratio and various hematopoietic progenitor cell percentages. More importantly, the gene-corrected β-Thal iPSC lines restored HBB expression and reduced reactive oxygen species production compared with the uncorrected group. Our study suggested that hematopoietic differentiation efficiency of β-Thal iPSCs was greatly improved once corrected by the CRISPR/Cas9 system, and the information gained from our study would greatly promote the clinical application of β-Thal iPSC-derived HSCs in transplantation.

    Beta-thalassemia is a genetic disorder that is caused by variations in the beta-hemoglobin (HBB) gene. Saudi Arabia is among the countries most affected by beta-thalassemia, and this is particularly problematic in the Eastern regions. This review article is an attempt to compile all the reported mutations to facilitate further national-level studies to prepare a Saudi repository of HBB gene variations. In Saudi Arabians, IVSI-5 (G>C) and Cd 39 (C>T) are the most prevalent HBB gene variations out of 42 variations. The coinheritance of HBB gene variations with ATRX, HBA1, HBA2, HBA12, AHSP, and KLF1 gene variations were observed to be common in the Saudi population. National surveys on the molecular nature of hemoglobinopathies should be set up through collaborations between research centers from various regions to create a well-documented molecular data bank. This data bank can be used to develop a premarital screening program and lead to the best treatment and prevention strategies for beta-thalassemia. PMID:29619482

    Background Myocardial iron overload is the most common cause of mortality in patients with thalassemia major (TM), also known as beta-thalassemia. T2* cardiovascular magnetic resonance imaging (MRI) is the best way of monitoring cardiac iron, and new echocardiographic techniques can be used to assess cardiac function. Objectives The aim of this study was to assess the systolic and diastolic right ventricular (RV) function of patients with TM using tissue Doppler imaging (TDI) and to determine whether this echocardiographic technique is an adequate diagnostic tool for the screening and detection of subclinical cardiac dysfunction. Patients and Methods Eighty-four patients with TM were evaluated by conventional echocardiography and pulse-wave TDI. The data of the TM group (Group 1) were compared with that of 85 age- and sex-matched healthy controls (Group 2). Cardiovascular T2* MRI examinations were performed in 49 of the 85 patients. Results The patients with TM had significantly lower values for weight, height, body mass index, systolic arterial pressure, deceleration time, E’/A’, and ejection time (ET) than the controls. Group 1 also had significantly higher values for peak early diastolic velocity (E) over peak late diastolic velocity (A), peak early diastolic velocity of TDI (E’), peak late diastolic velocity of TDI (A’), E/E’, isovolumetric relaxation time, isovolumetric contraction time, and RV magnetic perfusion imaging (MPI) than Group 2. Conclusions RV diastolic dysfunction occurs before systolic deterioration in patients with TM and cannot be screened with conventional echocardiographic techniques. In routine practice, TDI measurements, MPI (for global function) and the E/E’ parameter (for diastolic function) can be used to screen and detect early RV dysfunction. PMID:27617076

    We present in a brief summary the basic aspects of the most rational technologies used for new born screening (NBS) of the hemoglobinopathies and we report the preliminary results for the identification of beta-thalassemia carriers at birth by measuring the expression of the HbA fraction. Separation and measurement of the Hb fractions in 1.500 cord blood samples collected among the multi-ethnic Dutch population using different methods. By using a cut of thalassemia can be preselected at birth with a reasonable degree of sensitivity and be confirmed by parent analysis.

The first study on the relation of renal tubular dysfunction and β-thalassemia minor was performed in 2002 but those studies seem inadequate.The main goal of this study is through evaluation of renal tubular function in 100 patients with thalassemia minor. Materials & Methods: 100 patients with β- thalassemia which confirmed by hemoglobin electrophoresis and CBC as well as RBC indices were studied.14 out of 100 cases exit because of Urinary Tract Infection, diabetes mellitus or hypertension.Complete chemistry profile was performed on serum and urine of all reminder 86 patients (46 female and 40 male. Patients classified into two groups: β-thalassemia minor with anemia and without anemia. Another control group include 50 healthy individuals also considered.Then data analyzed by proper statistical methods. Results: 20 out of 86 reminder cases e.g. 24% showed at least one index of renal tubular dysfunction.58% of patients was been anemic and 42% non anemic. The most prominent tubular dysfunction was seen in a 29 years old lady with glucosuria and without anemia. conclusion: β-Thalassemia minor is common in Iran specially in Fars province. This study revealed significant renal tubular dysfunction in patient with β-thalassemia minor. So it is necessary to check out thalassemic patients for renal function tests periodically. Key words: β-thalassemia, minor,renal tubular dysfunction

It has also been proven that growth retardation is present in b-thalassemia major children despite regular transfusion and chelation. Our aim was to evaluate the level of IGF-1 in b-thalassemia minor subjects and compare it with that in healthy children. Material and Methods: Fifty children aged 6 months to 15 years with b-thalassemia minor (32 males, 18 females and 50 age- and sex-matched normal healthy children were selected. Medical history was taken and complete physical examination was done in each case; IGF-1 level was checked in all cases. This study was done in Shiraz, southern Iran, during 2005.Results: IGF-1 levels were significantly lower in b-thalassemia minor children than normal children (P = 0.015. This result demonstrates that some etiologies of growth failure in b-thalassemia major other than those described to date can exist, which may be shared with b-thalassemia minor in feature or may be transformed by genes that are either expressed or not.Conclusion: We conclude that in addition to that observed in b-thalassemia major, IGF-1 level is also decreased in b-thalassemia minor, and these two may have similar etiologies.

    Full Text Available Abstract Background Thalassemia is a common disorder worldwide with a predominant incidence in Mediterranean countries, North Africa, the Middle East, India, Central Asia, and Southeast Asia. Whilst substantial progress has been made towards the improvement of Health related quality of life (HRQoL in western countries, scarce evidence-based data exists on HRQol of thalassemia children and adolescents living in developing countries. Methods We studied 60 thalassemia children from Middle Eastern countries with a median age of 10 years (range 5 to 17 years. HRQoL was assessed with the Pediatric Quality of Life Inventory (PedsQL 4.0. The Questionnaire was completed at baseline by all patients and their parents. The agreement between child-self and parent-proxy HRQoL reports and the relationship between HRQoL profiles and socio-demographic and clinical factors were investigated. Results The scores of parents were generally lower than those of their children for Emotional Functioning (mean 75 vs 85; p = 0.002, Psychosocial Health Summary (mean 70.3 vs 79.1; p = 0.015 and the Total Summary Score (mean 74.3 vs 77.7 p = 0.047. HRQoL was not associated with ferritin levels, hepatomegaly or frequency of transfusions or iron chelation therapy. Multivariate analysis showed that a delayed start of iron chelation had a negative impact on total PedsQL scores of both children (p = 0.046 and their parents (p = 0.007. Conclusions The PedsQL 4.0 is a useful tool for the measurement of HRQoL in pediatric thalassemia patients. This study shows that delayed start of iron chelation has a negative impact on children’s HRQoL.

    Thalassemia is one of the most common genetic diseases in the world. It is a major health problem, brings much morbidity, early mortality and a great deal of misery for a family both financially and emotionally. The patients suffering from beta thalassemia major do not survive for more than 5 years without blood transfusion. Blood transfusion is usually administered every two to five weeks to maintain the pre-transfusion hemoglobin level of 9-10 gm/dL. This study carried out in the department of Transfusion Medicine of Mymensingh Medical College Hospital from January 2014 to June 2014. A total of 200 parents were interviewed. There was a slight preponderance of females which accounted for 57.5% of the parents. Ninety seven (45.5%) had an income less than Rs. 5000 per month. Nearly 50% were illiterate with only 24.5% with a higher education. Consanguinity was positive in 72.5% of the parents with extended family history of thalassemia positive in 40.8%. Only 29.5% were immunized against Hepatitis B. Around 27.5% did not know whether they should be immunized. Fifty five percent of parents knew children should receive Dysferol. Twelve percent were aware of consanguinity to be a risk factor for thalassaemia with only 5% having undergone antenatal diagnosis. Parental knowledge about thalassemia and its preventive measures is inadequate; this requires intervention in the form of public health education programs concentrating on high risk/targeted population.

    Skeletal changes among beta (β) thalassemia children are well documented, but without available data regarding sino-nasal passages alterations. The authors investigated the maxillary sinuses and sino-nasal passages changes in β-thalassemia children and correlated such changes with the amount of transfused red cells and the erythroid marrow activity. Clinical analyses including otorhinolaryngical examination (ORL) were obtained in twenty β-thalassemia children and 20 matched healthy controls. Hemoglobin (Hb), serum ferritin, soluble transferrin receptor (sTfR) levels and bone mineral density of the lumbar spine (BMD ls) were assayed. The two groups were analyzed for the CT image parameters: bone thickness, anterior and posterior choanae diameters, extramedullary hematopoiesis and chronic rhinosinusitis (CRS) RESULTS: Nasal congestion/obstruction was identified in 14 (70%) children. Eight patients (40%) had criteria of chronic rhinosinusitis. In comparison with the normal controls, the increase in the roof, floor, medial, anterior, lateral and posterior maxillary bony walls thickness was significantly higher (1.26, 2.46, 2.6, 2.9, 3.23 and 5.34-folds, respectively). The mean posterior choanae horizontal, vertical diameters and their surface area were significantly reduced in the patients compared to the controls. The mean anterior maxillary wall bone thickness directly correlated with sTfR (P=0.047) while that of the posterior wall correlated inversely with Hb level (P=0.013). The mean vertical posterior choanae diameter had positive correlation with the amount of transfused red cells (P=0.001) and negative correlation with sTfR (P=0.001). The Hounsfield unit of maxillary sinus wall had direct relation with BMDls (P=0.003) CONCLUSIONS: Thalassemia children are at risk of different folds increase of maxillary sinuses walls thicknesses utmost at posterior and lateral walls. Other sino-nasal morbidities include diminished posterior choanal diameter, nasal obstruction

    We describe the evaluation of the Bio-Rad BeTha Gene 1 kit (Bio-Rad Laboratories, Hercules, CA), a DNA-probe assay designed for the qualitative determination of the eight most common Mediterranean beta-thalassemia mutations. The kit utilizes the principle of allele-specific oligonucleotide (ASO) hybridization. Following sample preparation and in vitro DNA amplification by the polymerase chain reaction (PCR), an allele-specific detection of the amplified products by a nonradioactive enzymatic assay is performed. Genomic DNA is prepared from an individual's whole blood with a DNA purification matrix. In a second step, the beta-globin gene is amplified in a multiplex PCR reaction containing four 5' biotinylated oligonucleotide primers. In a final step, an aliquot of the PCR reaction is first chemically denatured and then captured in two eight-well strips of a 96-well enzyme-linked immunosorbent assay (ELISA) plate by hybridization to an immobilized ASO probe. Each DNA sequence at each of the eight mutation sites is represented by one normal and one mutant ASO. During this capture/hybridization step, which is performed at 37 degrees C, only perfectly matched PCR products will be captured by an ASO. Subsequently, the allele-specific captured biotin-labeled PCR products are detected by a colorimetric enzymatic reaction. The system permits the detection of 16 beta-thalassemia alleles using a high-throughput format that can be automated easily. A clinical feasibility study was performed to evaluate the functionality (method comparison study, assay validity using samples previously collected and stored at various temperatures for different periods of time, interference on kit performance, and assay validity for prenatal diagnosis) and the usability (ease of use, sample throughput) of the kit. The analysis of 110 samples previously studied with reference methods showed 100% clinical sensitivity and specificity. We demonstrate here that the procedure not only increases the

    Full Text Available OBJECTIVE: Sickle cell anemia and the interaction S/Beta thalassemia differ in hematological values due to microcytosis and hypochromia caused by the thalassemic mutation. The clinical benefit of long-term hydroxyurea treatment is undeniable in sickle cell disease with monitoring of the biological action of the drug being by the complete blood count. The objective of this work is to compare changes in some of the erythrocytic indexes between S/Beta thalassemia and sickle cell anemia patients on long-term hydroxyurea treatment. METHODS: The values of erythrocyte indexes (mean corpuscular volume and mean corpuscular hemoglobin were compared in a retrospective study of two groups of patients (Sickle cell anemia and S/Beta thalassemia on hydroxyurea treatment over a mean of six years. RESULTS: The quantitative values of the two parameters differed between the groups. Increases in mean corpuscular volume and reductions in mean corpuscular hemoglobin delay longer in S/Beta thalassemia patients (p-value = 0.018. CONCLUSION: Hematological changes are some of the beneficial effects of hydroxyurea in sickle cell disease as cellular hydration increases and the hemoglobin S concentration is reduced. The complete blood count is the best test to monitor changes, but the interpretation of the results in S/Beta thalassemia should be different.

    Analysis of fetal DNA in maternal plasma has recently been introduced for non-invasive prenatal diagnosis. We have now investigated the feasibility of polymerase chain reaction (PCR)/ligase detection reaction (LDR)/capillary electrophoresis for the detection of fetal point mutations, such as the beta-thalassemia mutation, IVS2 654(C --> T), in maternal plasma DNA. The sensitivity of LDR/capillary electrophoresis was examined by quantifying the mutant PCR products in the presence of a vast excess of non-mutant competitor template, a situation that mimics the detection of rare fetal mutations in the presence of excess maternal DNA. PCR/LDR/capillary electrophoresis was applied to detect the mutation, IVS2 654(C --> T), in an experimental model at different sensitivity levels and from 10 maternal plasma samples. Our results demonstrated that this approach to detect a low abundance IVS2 654(C --> T) mutation achieved a sensitivity of approximately 1:10,000. The approach was applied to maternal plasma DNA to detect the paternally inherited fetal IVS2 654(C --> T) mutation, and the results were equivalent to those obtained by PCR/reverse dot blot of amniotic fluid cell DNA. PCR/LDR/capillary electrophoresis has a very high sensitivity that can distinguish low abundance single nucleotide differences and can detect paternally inherited fetal point mutations in maternal plasma.

    Full Text Available Background: The prevalence of microcytosis in donors and Iron Deficiency Anemia (IDA and Beta-Thalassemia trait (BTT in microcytic and non-microcytic donors has not been studied in India. The present study aims at finding the same. Materials and Methods: Initially 925 donor samples were evaluated on cell-counter. Of these, 50 were found to be microcytic. These were subjected to Ferritin and HbA2 determination. Subsequently, an additional 51, age-and-sex matched non-microcytic donor samples were selected to serve as controls. These were subjected to the same tests. Results: The prevalence of microcytosis was 5.4% (50/925. Among the microcytic donors, 52% were IDA, 36% BTT, 8% both, and 4% none. In case of non-microcytic donors 29.4% were IDA, 3.9% BTT, and 66.7% none. Conclusions: The study revealed a high prevalence of IDA and BTT in blood donors and a higher probability of finding these in the microcytic samples. This prompted authors to suggest an algorithm for screening of blood donors for IDA and BTT. The algorithm recommends doing an hemogram on all donor samples, routinely. Ferritin could be done only in microcytic samples. At levels lower than15 ng/ml, it is diagnosed as IDA, and therefore, HPLC is performed only for non-IDA samples with Ferritin levels higher than 15 ng/ml. By employing this algorithm, a substantial number of IDA and BTT could be diagnosed while keeping the number of Ferritin tests small and the number of HPLC tests even smaller and thus making it cost efficient.

    Full Text Available Nonsense-mediated mRNA decay (NMD is a surveillance system to prevent the synthesis of non-functional proteins. In β-thalassemia, NMD may have a role in clinical outcome. An example of premature translation stop codons appearing for the first time is the β-globin cd39 mutation; when homozygous, this results in a severe phenotype. The aim of this study was to determine whether the homozygous nonsense cd39 may have a milder phenotype in comparison with IVS1,nt110/cd39 genotype. Genotypes have been identified from a cohort of 568 patients affected by β-thalassemia. These genotypes were compared with those found in 577 affected fetuses detected among 2292 prenatal diagnoses. The nine most common genotypes, each with an incidence rate of 1.5% or over, and together accounting for 80% of genotype frequencies, underwent statistical analysis. Genotype prevalence was calculated within the overall group. Results are expressed as proportions with 95% confidence intervals; P≤0.05 was considered statistically significant. A binomial distribution was assumed for each group; z-tests were used to compare genotype frequencies observed in the patient group with frequencies in the affected fetus group. In the absence of selecting factors, prevalence of these two genotypes was compared between a cohort of 568 β-thalassemia patients (PTS and 577 affected fetuses (FOET detected during the same period. IVS1,nt110/cd39 was significantly more prevalent in FOET than PTS (P<0.0001, while there was no significant difference in prevalence of cd39/cd39 in FOET compared with PTS (P=0.524. These results suggest a cd39 genotype NMD mechanism may be associated with improved clinical outcomes in thalassemia major. 无义介导的mRNA 降解(NMD) 是一种预防非功能性蛋白质合成的监控系统。在β地中海贫血中,NMD可能对临床结果有影响。第一次出现的过早终止密码子(PTC)为β珠蛋白cd39突变;若为纯合

    Full Text Available Beta (β thalassemia syndromes are a group of hereditary disorders characterized by a genetic deficiency in the synthesis of β-globin chains. In the homozygous state, β-thalassemia (i.e., thalassemia major causes severe transfusion-dependent anemia. Inherited β-thalassemia syndromes cause high degree of hemolytic anemia, recurrent fever, clinical jaundice, frequent infections, bossing of cheek bones, growth retardation, splenomegaly, etc. and are responsible for high infant morbidity, mortality and fetal wastage in India. The victims include the infants, growing children, adolescent girls, pregnant women and a large chunk of ignorant people. In view of heavy genetic load, frequent requirement of blood transfusions, high cost of treatment and management, physical trauma, and mental and psychological harassment to the patients and their families, it has been realized that preventive community health and genetics approach is the most suitable for India. After carrier detection, prenatal diagnosis, and genetic couselling are the important options for couples at high risk for β-thalassemia. A prerequisite for successful prevention and intervention approach in India is the health education, bringing public awareness, sensitization, and community screening for the identification of heterozygotes or carriers in the concerned community. Some suggestions for the prevention of β-thalassemia in the vulnerable communities of India have been over emphasized for amelioration.β地中海贫血综合症是一簇遗传性异常,其特点是β球蛋白链接合处基因缺失。β地贫(或重型地贫)在纯和状态下导致严重的输液依赖型贫血症。遗传性的β地贫综合症引起严重的溶血性贫血、回归热、显性黄疸、常见感染、疼痛危象、颊骨浮肿、生长迟缓、脾肿大等症状,这导致在印度出现婴儿高发病率、死亡率和胎儿夭折。其受害人群包括婴儿、发

    Traditional methods for thalassemia screening are time-consuming and easily affected by cell hemolysis or hemoglobin degradation in stored blood samples. Tandem mass spectrometry (MS/MS) proved to be an effective technology for sickle cell disorders (SCD) screening. Here, we developed a novel MS/MS method for β-thalassemia screening from dried blood spots (DBS). Stable isotopic-labeled peptides were used as internal standards for quantification and calculation of the α:β-globin ratios. We used the α:β-globin ratio cutoffs to differentiate between normal individuals and patients with thalassemia. About 781 patients and 300 normal individuals were analyzed. The α:β-globin ratios showed significant difference between normal and β-thalassemia patients (Pthalassemia mutation. In the parallel study, all cases screened for suspected thalassemia from six hundred DBS samples by using this MS/MS method were successfully confirmed by genotyping. The intra-assay and inter-assay CVs of the ratios ranged from 2.4% to 3.9% and 4.7% to 7.1%, and there was no significant sample carryover or matrix effect for this MS/MS method. Combined with SCD screening, this MS/MS method could be used as a first-line screening assay for both structural and expression abnormalities of human hemoglobin. Traditional methods for thalassemia screening were depending on the structural integrity of tetramers and could be affected by hemolysis and degradation of whole blood samples, especially when stored. We used proteospecific peptides produced by the tryptic digestion of each globin to evaluate the production ratio between α- and β-globin chains, which turned out to be quite stable even when stored for more than two months. Though most of the peptides were specific to α-globin or β-globin, we only chose four most informative peptides and its stable isotopic-labeled peptides as internal standards for analysis, which could obtain a high accuracy. Currently, we are the first to address the

    2002-11-01

    Full Text Available Abstract Background Beta thalassemia major requires regular blood transfusions and iron chelation to alleviate the harmful accumulation of iron. Evidence on the efficacy and safety of the available agents, desferrioxamine and deferiprone, is derived from small, non-comparative, heterogeneous observational studies. This evidence was reviewed to quantitatively compare the ability of these chelators to reduce hepatic iron. Methods The literature was searched using Medline and all reports addressing the effect of either chelator on hepatic iron were considered. Data were abstracted independently by two investigators. Analyses were performed using reported individual patient data. Hepatic iron concentrations at study end and changes over time were compared using ANCOVA, controlling for initial iron load. Differences in the proportions of patients improving were tested using χ2. Results Eight of 11 reports identified provided patient-level data relating to 30 desferrioxamine- and 68 deferiprone-treated patients. Desferrioxamine was more likely than optimal dose deferiprone to decrease hepatic iron over the average follow-up of 45 months (odds ratio, 19.0, 95% CI, 2.4 to 151.4. The degree of improvement was also larger with desferrioxamine. Conclusions This analysis suggests that desferrioxamine is more effective than deferiprone in lowering hepatic iron. This comparative analysis – despite its limitations – should prove beneficial to physicians faced with the challenge of selecting the optimal treatment for their patients.

    Thalassaemia major (TM) is a hereditary blood disease characterised by reduced or absent production of beta globin chains. Erythrocyte transfusions are given to raise the haemoglobin level in patients with thalassaemia major. However, transfusions have been related to increased risk of iron overload and tissue damage related to excess iron. Both elevated oxidative stress due to iron overload and increased hemolysis lead to over utilisation of minerals required for antioxidant enzymes activities. Iron chelators have been used to prevent iron overload in thalassaemia major patients, but these chelators have the possibility of removing minerals from the body. Thalassaemia patients are more at risk for mineral deficiency because of increased oxidative stress and iron chelation therapies. Growth and maturational delay, cardiomyopathy, endocrinopathies and osteoporosis are the complications of thalassaemia. Minerals may play a particular role to prevent these complications. In the current review, we provide an overview of minerals including zinc (Zn), copper (Cu), selenium (Se), magnesium (Mg) and calcium (Ca) in thalassaemia major patients. We, also, underline that some complications of thalassaemia can be caused by an increased need for minerals or lack of the minerals. Copyright © 2017 Elsevier GmbH. All rights reserved.

  5. Plasma fibronectin in patients undergoing major surgery

    Plasma fibronectin in patients undergoing major surgery had been determined before and after operation. The study was done on 15 patients and 15 normal healthy individuals. The study revealed that patients subjected to major operation, their fibronectin level was normal before operation followed by reduction one day post-operation. After one week, fibronectin level raised again nearly to the pre-operations levels. The probable mechanisms of fibronectin in healing processes were discussed. Fibronectin (FN) is a family of structurally and immunologically related high molecular weight glycoproteins that are present in many cell surfaces, in extracellular fluids, in connective tissues and in most membranes. Interaction with certain discrete extracellular substances, such as a glucosaminoglycans (e.g. heparin), fibrin and collagen and with cell surface structure seem to account for many of its biological activities, among which are regulation of adhesion, spreading and locomotion (Mosesson and amrani, 1980). The concentration of Fn in human plasma decreases after extensive destruction such as that occurs in major surgery, burns or other trauma. This decrease has been generally though to be due to increased consumption of soluble plasma Fn in opsonization of particulate and soluble debris from circulation by the reticuloendothelial (RE) system. Fn rapidly appears in injury areas, in experimentally induced blisters, wounded and epithelium tissues (Petersen et al., 1985). Fn accumulates at times of increased vascular permeability and it is produced by cell of blood vessels in response to injury

    Full Text Available Thalassemias are a heterogeneous group of inherited disorders characterized by a microcytic hypochromic anemia and an imbalance in the synthesis of the globin-chains. Hb C is the second most frequently variant of hemoglobin found in Brazil. The laboratory diagnosis of hemoglobinopathies, including thalassemias, is growing in importance, particularly because of an increasing requirement for neonatal diagnosis of abnormal hemoglobins. Screening tests were carried out using alkaline and acid electrophoresis, globin-chain analysis by cellulose acetate in alkaline pH, isoelectric focusing and HPLC. The molecular characterization was made by PCR-ASO for Hb C and beta thalassemia mutants. Large-scale screening and discriminative methodologies must provide information about the hemoglobin polymorphisms in Brazilian population. HPLC is a powerful tool in these cases. Molecular characterization is important to genetic counseling and clinical management, in particular for the Brazilian population that have an intense racial admixture, with great variability of hemoglobins. In this paper an association between Hb C and beta thalassemia (IVS-II-654 in a black family from Brazil was described.

    Full Text Available Xmn-1 polymorphism is a known factor, which increases fetal haemoglobin production. Among the inherited disorders of blood, thalassaemia and SCD constitutes a major bulk of genetic diseases in India.  Our aim was to verify the role of the Xmn I polymorphism as a modulating factor in sickle cell patients and frequency of the polymorphism in Indian sickle cell patients. Subjects were 60 sickles homozygous and 75 sickle beta thalassemia patients. 5 ml blood   samples collected from patients. Screening of sickle patients done by HPLC. An automated cell analyzer SYSMEX (K-4500 Model used to analyze the CBC of patients.Xmn1 polymorphism analysis done by PCR-RFLP and Statistical analysis was performed on GraphPad static’s software. t test applied to compare the means amongst group. Among the sickle homozygous 27 were   heterozygous (+/- and 19 were   homozygous (+/+ while 30 were heterozygous and 24 were homozygous in sickle β-thalassemia patients. Extremely significant differences (p-value <0.001 of hematological parameters seen among patient with xmn-1 carrier and without the xmn-1 carrier. In our cases the clinical symptom less frequent and higher HbF level with Xmn-1 carriers. Presence of Xmn-1 polymorphism in sickle patients with higher HbF that improve phenotypic presentation in the sickle cell patients. We conclude that the phenotype of Indian sickle cell patients influenced by Xmn-1 polymorphism.

    Contaxt: Every year in India 6000 to 8000 children are born with thalassaemia major. The birth of such a child produces considerable physical and economic strain on the affected child, its family and the community at large. Thus, the emphasis must shift from the treatment to the prevention of such births in the future. To find out the prevalence of the Beta Thalassaemia trait among the pregnant women who attended the antenatal clinics in a Primary Health Centre, by using the NESTROF test; to describe the socio-demographic characteristics of the study subjects, to find out the pregnancies which were 'at risk' of delivering babies with Thalassaemia major and to find out the 'awareness' of the pregnant women regarding Thalassaemia. This exploratory study was conducted in a PHC which was attached to the Department of Community Medicine of a medical college which was situated in Bangalore, India, for a period of 3 months. All the pregnant women who attended the antenatal clinic and the husbands of the NESTROF positive women were included in the study. The details regarding the sociodemographic characteristics of the women were collected on a structured proforma and the NESTROF test was performed. Out of the 210 pregnant women who were tested, 18 (8.5%) were thalassaemia carriers. 12 (66.6%) of them were between 20 - 25 years of age. 5 (27.7%) were born out of 2(nd) degree consanguineous marriages. 7 (38.8%) had a history of abortions, among which 6 (33.3%) were in the 1(st) trimesters of their pregnancies. Out of the 18 positive women, 9 (50%) had turned up with their husbands. All of the husbands were negative for the Thalassaemia carrier status. Thus, there was no pregnancy which was at a risk of delivering babies with thalassaemia major. None (100%) of the pregnant women were aware of the disease, thalassaemia. The prevalence of the Beta Thalassaemia trait among the pregnant women was 8.5%.

    Thalassemia can lead to severe transfusion-dependent anemia, and it is the most common genetic disorder in Malaysia. This paper aims to determine the prevalence of thalassemia in the Kadazandusuns, the largest indigenous group in Sabah, East Malaysia. α- and β-thalassemia were confirmed in 33.6% and 12.8%, of the individuals studied respectively. The high prevalence of α- and β-thalassemia in the Kadazandusuns indicates that thalassemia screening, genetic counseling, and prenatal diagnosis should be included as part of their healthcare system. This preliminary paper serves as a baseline for further investigations into the health and genetic defects of the major indigenous population in Sabah, East Malaysia.

    β-thalassemia is a common autosomal recessive disorder characterized by a deficiency in the synthesis of β-chains. Evidences show that increased HbF levels improve the symptoms in patients with β-thalassemia or sickle cell anemia. In this study, ZFN technology was applied to induce a mutation in the binding domain region of SOX6 to reactivate γ-globin expression. The sequences coding for ZFP arrays were designed and sub cloned in TDH plus as a transfer vector. The ZFN expression was confirmed using Western blot analysis. In the next step, using the site-directed mutagenesis strategy through the overlap PCR, a missense mutation (D64V) was induced in the catalytic domain of the integrase gene in the packaging plasmid and verified using DNA sequencing. Then, the integrase minus lentivirus containing ZFN cassette was packaged. Transduction of K562 cells with this virus was performed. Mutation detection assay was performed. The indel percentage of the cells transducted with lenti virus containing ZFN was 31%. After 5 days of erythroid differentiation with 15 μg/mL cisplatin, the levels of γ-globin mRNA were sixfold in the cells treated with ZFN compared to untreated cells. In the meantime, the measurement of HbF expression levels was carried out using hemoglobin electrophoresis and showed the same results. Integrase minus lentivirus can provide a useful tool for efficient transient gene expression and helps avoid disadvantages of gene targeting using the native virus. The ZFN strategy applied here to induce indel on SOX6 gene in adult erythroid progenitors may provide a method to activate fetal hemoglobin expression in individuals with β-thalassemia. © 2017 Wiley Periodicals, Inc.

    Extramedullary hematopoiesis (EH) is a compensatory phenomenon that results in the production of blood cell precursors outside the marrow in patients with chronic hemolytic anemia and ineffective erythropoiesis. EH usually involves the liver, spleen, and lymph nodes. It can also be found at paravertebral, intrathoracic, or pelvic locations. Intracranial EH is a rare entity and often asymptomatic but can sometimes lead to symptomatic tumor-like masses. Treatment options are controversial and include hypertransfusion, surgical excision, radiotherapy, and hydroxyurea (HU). Successful treatment of an intracranial EH mass with HU and blood transfusions in a beta-thalassemia major patient was discussed along with a review of the published literature on intracranial EH in thalassemia. In our patient, the extramedullary hematopoietic mass in the interhemispheric fissure showed a marked improvement after 6 months of HU and hypertransfusion therapy. In the English literature, there are a few cases with intracranial EH and thalassemia, which were treated with different treatment modalities, with different outcomes. There is no standard treatment approach in patients with symptomatic EH. HU with hypertransfusion regimen is a reasonable first-choice modality in treating intracranial EH masses. © 2012 American Association of Blood Banks.

    The beta-thalassemias (β- thalassemias) are among the most common autosomal recessive disorders. They have a remarkably high frequency in the Mediterranean region and represent one of the most common genetic diseases in Egypt. In this study, the spectrum of P- thalassemia mutations and genotype-to-phenotype correlations were defined in 32 β- thalassaemic patients (β- thalassemias major and intermedia) with varying disease severity in two cities of the Suez Canal region. Ten different mutations were identified and the most frequent ones were: Isi-6 (T-C) (37.5%), IVSI-110 (G-A) (34.4%) and both IVSI-1 (G-A), IVSII-745 (C-G) and -102 (C-G) (12.5% each). There was a wide spectrum of phenotypic severity in all patients. We studied the Xmnl polymorphism (C/T) in γ- globin gene position -158 of P- thalassemia as a modulating factor of the disease severity. Presence of the polymorphism was found in two patients and this was not sufficient to explain the diversity of the phenotype encountered. Co-inheritance of alpha thalassaemia as a modulating factor was not evident in our patients. In conclusion, we have been unable to find a molecular basis for the benign clinical course in all our patients. Other genetic or acquired factors must be hypothesized which ameliorate the clinical condition.

    Full Text Available Abstract Background Trials of iron chelator regimens have increased the treatment options for cardiac siderosis in beta-thalassemia major (TM patients. Treatment effects with improved left ventricular (LV ejection fraction (EF have been observed in patients without overt heart failure, but it is unclear whether these changes are clinically meaningful. Methods This retrospective study of a UK database of TM patients modelled the change in EF between serial scans measured by cardiovascular magnetic resonance (CMR to the relative risk (RR of future development of heart failure over 1 year. Patients were divided into 2 strata by baseline LVEF of 56-62% (below normal for TM and 63-70% (lower half of the normal range for TM. Results A total of 315 patients with 754 CMR scans were analyzed. A 1% absolute increase in EF from baseline was associated with a statistically significant reduction in the risk of future development of heart failure for both the lower EF stratum (EF 56-62%, RR 0.818, p Conclusion These data show that during treatment with iron chelators for cardiac siderosis, small increases in LVEF in TM patients are associated with a significantly reduced risk of the development of heart failure. Thus the iron chelator induced improvements in LVEF of 2.6% to 3.1% that have been observed in randomized controlled trials, are associated with risk reductions of 25.5% to 46.4% for the development of heart failure over 12 months, which is clinically meaningful. In cardiac iron overload, heart mitochondrial dysfunction and its relief by iron chelation may underlie the changes in LV function.

    Trauma is a leading cause of death and disability worldwide. Patients presenting with severe trauma and burns benefit from specifically trained multidisciplinary teams. Regional trauma systems have shown improved outcomes for trauma patients. The aim of this study is to determine whether the development of major trauma systems have improved the management of patients with major burns. A retrospective study was performed over a four-year period reviewing all major burns in adults and children received at a regional burns centre in the UK before and after the implementation of the regional trauma systems and major trauma centres (MTC). Comparisons were drawn between three areas: (1) Patients presenting before the introduction of MTC and after the introduction of MTC. (2) Patients referred from MTC and non-MTC within the region, following the introduction of MTC. (3) Patients referred using the urban trauma protocol and the rural trauma protocol. Following the introduction of regional trauma systems and major trauma centres (MTC), isolated burn patients seen at our regional burns centre did not show any significant improvement in transfer times, admission resuscitation parameters, organ dysfunction or survival when referred from a MTC compared to a non-MTC emergency department. There was also no significant difference in survival when comparing referrals from all hospitals pre and post establishment of the major trauma network. No significant outcome benefit was demonstrated for burns patients referred via MTCs compared to non-MTCs. We suggest further research is needed to ascertain whether burns patients benefit from prolonged transfer times to a MTC compared to those seen at their local hospitals prior to transfer to a regional burns unit for further specialist care.

    Major trauma causes unanticipated critical illness and patients have often made few arrangements for what are sudden and life-changing circumstances. This can lead to financial, housing, insurance, legal and employment issues for patients and their families.A UK law firm worked with the major trauma services to develop a free and comprehensive legal service for major trauma patients and their families at a major trauma centre (MTC) in the UK. In 2013, a legal service was established at North Bristol NHS Trust. Referrals are made by trauma nurse practitioners and it operates within a strict ethical framework. A retrospective analysis of the activity of this legal service between September 2013 and October 2015 was undertaken. 66 major trauma patients were seen by the legal teams at the MTC. 535 hours of free legal advice were provided on non-compensation issues-an average of 8 hours per patient. This initiative confirms a demand for the early availability of legal advice for major trauma patients to address a range of non-compensation issues as well as for identification of potential compensation claims. The availability of advice at the MTC is convenient for relatives who may be spending the majority of their time with injured relatives in hospital. More data are needed to establish the rehabilitation and health effects of receiving non-compensation advice after major injury; however, the utilisation of this service suggests that it should be considered at the UK MTCs. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Full Text Available β-thalassemia major is a disease caused by β polypeptide chain synthesis disorder which is inherited as an autosomal recessive from both parents which is marked by little or no β globin chain synthesis. Medication for β thalassemia major patients is by repeated blood transfusions, which causes hemochromatosis. Hemochromatosis can occur in various organs including the pancreas. The aim of the study was to assess the alteration of plasma glucose concentration and the hemochromatosis prevalence. Fasting plasma glucose concentration and serum ferritin examination were measured in 115 β thalassemia major patients with ages between 10-23 years who were out-patients in the Thalassemia Centre, Department of Child Health, Medical School, University of Indonesia / Dr. Cipto Mangunkusumo General Hospital, Jakarta. The plasma glucose concentration examination was conducted by the GDH enzymatic method, with American Diabetes Association (ADA criteria in the evaluation, while the serum ferritin examination was conducted with the microparticle enzyme immuno assay (MEIA method. All patients had hemochromatosis, 14.8% of the patients had impaired fasting glucose level and 2.6% of the patients showed indications of diabetes mellitus. β thalassemia major patients who receive frequent transfusions will develop hemochromatosis that will in turn impair the pancreatic function.

    In Brazil, there have been no previous studies of Toxoplasma gondii infection in sickle cell anemia patients and carriers of severe forms of beta-thalassemia. This study evaluated T. gondii infection in patients with beta-hemoglobinopathies. A total of 158 samples, 77 (48.7%) men and 81 (51.3%) women, were evaluated. Three groups were formed: G1 (85 patients with sickle cell disease); G2 (11 patients with homozygous beta-thalassemia; G3 (62 patients with heterozygous beta-thalassemia). ELISA was employed to identify anti-T. gondii IgM and IgG antibodies, and molecular analysis was performed to determine beta-hemoglobin mutations. Fisher's exact test was used to compare frequencies of anti-T. gondii IgM and IgG antibodies in respect to gender and age. Anti-T. gondii IgG antibodies were found in 43.5% of individuals in G1, 18.1% in G2 and 50% in G3. All samples from G1 and G2 were seronegative for anti-T. gondii IgM antibodies, but 3.2% from G3 were seropositive. Considering anti-T. gondii IgG antibodies, no statistical significant differences were found between these groups nor in seroprevalence between genders within each group. Despite this, comparisons of the mean ages between G1, G2 and G3 were statistically significant (G2 vs. G1: p value = 0.0001; G3 vs. G1: p-value <0.0001; G3 vs. G2: p-value = 0.0001). A comparison by age of patients with sickle cell anemia showed a trend of lower risk of infection among younger individuals. Therefore, this study demonstrates that T. gondii infection occurs in patients with beta-thalassemia and sickle cell anemia in Brazil as seen by the presence of anti-T. gondii IgM and IgG antibodies.

    Objective: The study was conducted to evaluate the effects of blood transfusion(s) on the haematological picture of beta-thalassaemia major. Results: Out of the 280 patients 109 (39%) had received one or more blood transfusions (cases). The remaining 171 patients who did not receive any transfusion served as controls. The mean MCV, MCH and Hb-F in cases were significantly higher than in the controls (p 4 transfusions (17%) (p=0.016). In the occasionally transfused patients Hb-F level was directly related to the time since last transfusion. In 44/109 (40%) transfused patients (Hb-F>30%) the diagnosis of thalassaemia was not difficult. In 54/109 (50%) patients (Hb-:5-30%) the diagnosis was aided by parent's study, while PCR for thalassaemia mutation was required in 11/109 (10%) patients (Hb-F <5%). Conclusion: In most transfused patients of thalassaemia major MCV and MCH were significantly higher while Hb-F was lower than in the un-transfused patients. There was a linear correlation between Hb-F level and time since last transfusion in the occasionally transfused patients. However, the reduction in Hb-F level was more marked and sustained in multipally transfused patients. Parent's study and PCR are useful aids in establishing the correct diagnosis in these patients.

    Full Text Available Objective. To assess body composition in adult male and female patients with thalassemia major by dual-energy X-ray absorptiometry (DXA and to compare the findings with a group of healthy age-matched controls. Methods. Our study group included sixty-two patients (27 males, mean age 36 years, and 35 females, mean age 36.4 years and fifteen age-matched healthy controls. All patients had an established diagnosis of thalassemia major and followed a regular blood transfusion scheme since childhood and chelation treatment. Fat, lean, and bone mineral density (BMD were assessed with dual-energy X-ray absorptiometry. Ferritin levels and body mass index of all patients and controls were also recorded. Student t-test and Wilcoxon test were performed and statistical significance was set at p<0.05. Results. BMD and whole body lean mass are lower in both male and female adult patients compared with controls (p<0.01 in both groups, whereas whole body fat mass was found to have no statistically significant difference compared to controls. Regional trunk fat around the abdomen was found to be lower in male patients compared to controls (p=0.02. Conclusion. Severe bone loss and diminished lean mass are expected in adult male and female patients with thalassemia major. Fat changes seem to affect mainly male patients.

    Full Text Available BACKGROUND Thalassemia major patients are dependent on frequent blood transfusion and consequently develop iron overload. HFE gene mutations (C282Y, H63D and S65C in hereditary haemochromatosis has been shown to be associated with iron overload. The study aims at finding the association of HFE gene mutations in β-thalassemia major patients. MATERIALS AND METHODS A descriptive observational pilot study was conducted including fifty diagnosed -thalassemia major cases. DNA analysis by PCR-RFLP method for HFE gene mutations was performed. RESULTS Only H63D mutation (out of three HFE gene mutations was detected in 8 out of 50 cases. Observed frequency of H63D mutation was 16%. While frequency of C282Y and S65C were 0% each. CONCLUSION The frequency of HFE mutation in -thalassemia major is not very common.

    Full Text Available Abstract Although thousands of studies have examined the genetics, epidemiology, etiology, biology, treatment and prevention of major depressive disorder, we still lack very basic knowledge about what patients with depressive disorders need. Despite the thousands of studies that have been conducted on major depression and the hundreds of randomized trials that have examined the effects of treatments, many patients still do not know how to cope with the daily problems caused by depressive disorders. In this Commentary the need for more research on the perspectives of patients is described. This research should guide treatment studies as well as basic research much more than it currently does. This perpective is especially important to understand and solve the undertreatment of depression, one of the major problems in this area. Up to 50% of depressed patients do not seek treatment, resulting in huge avoidable disease burden and economic costs. In order to solve this problem we need a better understanding of the problems patients encounter in daily life, and what factors contribute to the reasons for seeking treatment or not. Research from the patients' perspective is also necessary to meet the currently unmet information needs of patients, including information about the nature and causes of depression, stigma, medication, treatment and coping with the daily problems of having depression.

    Pregnant women with major mental disorders present obstetricians with a range of clinical challenges, which are magnified when a psychotic or agitated patient presents in labor and there is limited time for decision making. This article provides the obstetrician with an algorithm to guide professionally responsible decision making with these patients. We searched for articles related to the intrapartum management of pregnant patients with major mental disorders, using 3 main search components: pregnancy, chronic mental illness, and ethics. No articles were found that addressed the clinical ethical challenges of decision making during the intrapartum period with these patients. We therefore developed an ethical framework with 4 components: the concept of the fetus as a patient; the presumption of decision-making capacity; the concept of assent; and beneficence-based clinical judgment. On the basis of this framework we propose an algorithm to guide professionally responsible decision making that asks 5 questions: (1) Does the patient have the capacity to consent to treatment?; (2) Is there time to attempt restoration of capacity?; (3) Is there an opportunity for substituted judgment?; (4) Is the patient accepting treatment?; (5) Is there an opportunity for active assent?; and (6) coerced clinical management as the least worst alternative. The algorithm is designed to support a deliberative, clinically comprehensive, preventive-ethics approach to guide obstetricians in decision making with this challenging population of patients.

    Objective: To determine the frequency of short stature in children with - thalassemia major receiving multiple transfusions at Military Hospital Rawalpindi. Study Design: Descriptive cross sectional study. Place and Duration of Study: Study was conducted at Military Hospital from 1st January 2010 to 30th June 2010. Subjects and Methods: Total 100 multi-transfused cases of - thalassemia major were included in the study. The height of every child was measured in centimeters using the same free-standing standard stadiometer, and the same technique by a single pediatrician. Results: Out of 100 patients of - thalassemia major 57.0% (n=57) were male while 43% (n=43) were female. Mean age was 9.94 years (SD +- 2.93) with range of 6 to 14 years. Mean height was 115.77 cm (SD +- 13.79) with range of 72.00 to 148.00 cm. 57.0% (n=57) were found to be short statured while 43.0% (n=43) were with normal height. Mean age of short statured patients was 11.61 +- 2.34 years and mean age of patients with normal height was 7.73 +- 2.05 years. Conclusion: The frequency of short stature in our patients with - thalassemia major receiving multiple transfusions is high. There is need to monitor the height of thalassemic children regularly and to improve the quality of care being provided to them so as to improve their quality of life. (author)

  8. Pharmacological prevention of suicide in patients with major mood disorders.

    Rihmer, Zoltan; Gonda, Xenia

    2013-12-01

    The risk of self-destructive behavior in mood disorders is an inherent phenomenon and suicidal behavior in patients with unipolar or bipolar major mood disorders strongly relates to the presence and severity of depressive episodes. Consequently, early recognition, and successful acute and long-term treatment of depressive disorders is essential for suicide prevention in such patients. Large-scale, retrospective and prospective naturalistic long-term clinical studies, including severely ill, frequently suicidal depressives show that appropriate pharmacotherapy markedly reduces suicide morbidity and mortality even in this high-risk population. Supplementary psycho-social interventions further improve the effect. The slightly elevated (but in absolute sense quite low) risk of suicidal behavior among patients taking antidepressants compared to those taking placebo in randomized controlled antidepressant trials on unipolar major depression might be the consequence of the depression-worsening potential of antidepressant monotherapy in subthreshold and mixed bipolar depressed patients included in these trials and falsely diagnosed as suffering from unipolar major depression. Concurrent depression-focused psychotherapies increase the effectiveness of pharmacotherapy and this way contribute to suicide prevention for patients with mood disorders.

The laboratory plays an important role in the investigation of the thalassemias and hemoglobinopathies. Cellulose acetate electrophoresis at alkaline pH and diagnosis based mainly on visual impression of thickness of band may miss the thalassemic trait patients. The aim of this study was to find out different hemoglobinopathies and thalassemia presenting in our hospital and to compare electrophoresis results with HPLC.Materials and Methods: This study was performed in the hematopathology section of Department of Pathology of Tribhuvan University Teaching Hospital on cases sent for electrophoresis during 18 months period from October 2013 to March 2015 and included hemoglobinopathies and thalassemias identified by either electrophoresis or HPLC. 97 cases fulfilled the inclusion criteria and thus were included in the study. Electrophoresis at alkaline pH was done in all whereas HPLC was performed in 27 cases.Results: A sharp peak of hemoglobinopathies and thalassemias was seen in Tharu community though other communities are also affected. Thalassemia trait was the most common diagnosis (26.8% followed by sickle cell anemia (21.6%.  Electrophoresis was efficient in detecting some alpha thalassemia variants but missed many cases of beta thalassemia trait.Conclusion: Beta Thalassemia trait and sickle cell anemia both are common in Nepal , along with some other hemoglobinopathies  A sharp peak of hemoglobinopathies and thalassemias are seen in Tharu community. These abnormal hemoglobins and thalassemias are mainly seen in Terai region. Electrophoresis fails to quantify hemoglobin percentage and thus is not appropriate test in beta thalassemia screening.

    Fluid resuscitation is one of the critical treatments for the major burn patient in the early phases after injury. We evaluated the practice of fluid resuscitation for severely burned patients with the Third Military Medical University (TMMU) protocol, which is most widely used in many regions of China. Patients with major burns (>30% total body surface area (TBSA)) presenting to Southwest Hospital, Third Military Medical University, between January 2005 and October 2007, were included in this study. Fluid resuscitation was initiated by the TMMU protocol. A total of 71 patients were (46 adults and 25 children) included in this study. All patients survived the first 48 h after injury smoothly and none developed abdominal compartment syndrome or other recognised complications associated with fluid resuscitation. The average quantity of fluid infused was 3.3-61.33% more than that calculated based on the TMMU protocol in both adult and paediatric groups. The average urine output during the first 24h after injury was about 1.2 ml per kg body weight per hour in the two groups, but reached 1.2 ml and 1.7 ml during the second 24h in adult and pediatric groups, respectively. This study indicates that the TMMU protocol for fluid resuscitation is a feasible option for burn patients. Individualised resuscitation - guided by the physiological response to fluid administration - is still important as in other protocols.

    Abnormal decision-making processes have been observed in patients with major depressive disorder (MDD). However, it is unresolved whether MDD patients show abnormalities in decision making in a social interaction context, in which decisions have actual influences on both the self-interests of the decision makers per se and those of their partners. Using a well-studied ultimatum game (UG), which is frequently used to investigate social interaction behavior, we examined whether MDD can be associated with abnormalities in social decision-making behavior by comparing the acceptance rates of MDD patients (N = 14) with those of normal controls (N = 19). The acceptance rates of the patients were lower than those of the normal controls. Additionally, unfair proposals were accepted at similar rates from computer partners and human partners in the MDD patients, unlike the acceptance rates in the normal controls, who were able to discriminatively treat unfair proposals from computer partners and human partners. Depressed patients show abnormal decision-making behavior in a social interaction context. Several possible explanations, such as increased sensitivity to fairness, negative emotional state and disturbed affective cognition, have been proposed to account for the abnormal social decision-making behavior in patients with MDD. This aberrant social decision-making behavior may provide a new perspective in the search to find biomarkers for the diagnosis and prognosis of MDD.

They may worsen outcome and cause economic burden. The primary objective was to examine the prevalence of psychiatric comorbidities in MDD. The secondary objectives were to compare the presence of comorbidities between currently active and past MDD, and between patients with and without suicidal risk.Methods: This was a cross-sectional study. A total of 250 patients with lifetime MDD and age ≥18 years were enrolled. The Mini International Neuropsychiatric Interview (MINI, Thai version, was used to confirm MDD diagnosis and classify comorbidities. MDD diagnosis was confirmed in 190, and 60 patients were excluded due to diagnosis of bipolar disorder.Results: Of the 190 MDD patients, 25.8% had current MDD and 74.2% had past MDD. Eighty percent were women. The mean age at enrollment was 50 years, and at MDD onset was 41 years. Most patients were married (53.2%, employed (54.8%, and had ≥12 years of education (66.9%. There were 67 patients (35.3% with one or more psychiatric comorbidities. Comorbidities included dysthymia (19.5%, any anxiety disorders (21.1% (panic disorder [6.8%], agoraphobia [5.8%], social phobia [3.7%], obsessive–compulsive disorder [OCD] [4.7%], generalized anxiety disorder [5.3%], and post-traumatic stress disorder [4.2%], alcohol dependence (0.5%, psychotic disorder (1.6%, antisocial personality (1.1%, and eating disorders (0%. Compared with past MDD, the current MDD group had significantly higher OCD (P<0.001, psychotic disorder (P=0.048, past panic disorder (P=0.017, and suicidal risk (P<0.001. Suicidal risk was found in 32.1% of patients. Patients with suicidal risk had more comorbid anxiety disorder of any type (P=0.019 and

    In daily life, many decisions of minor and major importance have to be made. Thereby, intuitive judgments serve as useful guides and help us to adapt to our environment. People with major depressive disorder (MDD) often have difficulties to come to decisions. Is their intuition impaired? Since this question has not been addressed until now, the present study explored intuition in MDD. Depressed patients (n = 29) and healthy control participants (n = 27) completed the Judgment of Semantic Coherence Task, a well-established paradigm used in basic cognitive research to measure intuition. Furthermore, participants' severity of depressive symptoms (BDI-II), negative affect (PANAS), and rumination (RSQ) were assessed. All participants were interviewed with the SCID. Depressed patients showed impaired intuition compared to healthy control participants. In the depressed sample, negative affect accounts for the association between rumination and impaired intuition. Results further reveal that negative affect overall mediates the depression-intuition relationship. Patients with diminished ability to concentrate or indecisiveness had lower intuition indices compared to patients who did not fulfil this diagnostic criterion of MDD. The study introduces the phenomenon of intuition into depression research. Additionally, these results extent findings from basic research showing that induced negative mood as well difficulties to down-regulate negative affect impair intuitive coherence judgments. Current results indicate that the negative affectivity of patients is the crucial mediator in the association between depression and impaired intuition. Limitations of the study as well as the potential etiological role of intuition in MDD are discussed. The finding that intuition is impaired in depressed patients extends our knowledge as to the cognitive profile of patients with MDD. Patients who suffer from indecisiveness have lower intuition indices compared to patients who do not

    Full Text Available Heart disease is the leading cause of mortality and one of the main causes of morbidity in beta-thalassemia. Patients with homozygous thalassemia may have either a severe phenotype which is usually transfusion dependent or a milder form that is thalassemia intermedia.  The two main factors that determine cardiac disease in homozygous β thalassemia are the high output state that results from chronic tissue hypoxia, hypoxia-induced compensatory reactions and iron overload.  The high output state playing a major role in thalassaemia intermedia and the iron load being more significant in the major form. Arrhythmias, vascular involvement that leads to an increased pulmonary vascular resistance and an increased systemic vascular stiffness and valvular abnormalities also contribute to the cardiac dysfunction in varying degrees according to the severity of the phenotype.  Endocrine abnormalities, infections, renal function and medications can also play a role in the overall cardiac function.  For thalassaemia major, regular and adequate blood transfusions and iron chelation therapy are the mainstays of management. The approach to thalassaemia intermedia, today, is aimed at monitoring for complications and initiating, timely, regular transfusions and/or iron chelation therapy.  Once the patients are on transfusions, then they should be managed in the same way as the thalassaemia major patients.  If cardiac manifestations of dysfunction are present in either form of thalassaemia, high pre transfusion Hb levels need to be maintained in order to reduce cardiac output and appropriate intensive chelation therapy needs to be instituted.  In general recommendations on chelation, today, are usually made according to the Cardiac Magnetic Resonance findings, if available.  With the advances in the latter technology and the ability to tailor chelation therapy according to the MRI findings as well as the availability of three iron chelators, together with

    Full Text Available In this study, volatile urinary components were collected using three different types of samples from patients suffering from urinary incontinence (UI: (1 urine (A; (2 urine + non-used pad (B; and (3 urine + used pad (C. In addition, urine + non-used pad (D samples from non-patients were also collected as a reference. The collection of urinary volatiles was conducted with the aid of a glass impinger-based mini-chamber method. Each of the four sample types (A through D was placed in a glass impinger and incubated for 4 hours at 37 °C. Ultra pure air was then passed through the chamber, and volatile urine gas components were collected into Tedlar bags at the other end. These bag samples were then analyzed for a wide range of VOCs and major offensive odorants (e.g., reduced sulfur compounds (RSCs, carbonyls, trimethylamine (TMA, ammonia, etc.. Among the various odorants, sulfur compounds (methanethiol and hydrogen sulfide and aldehydes (acetaldehyde, butylaldehyde, and isovaleraldehyde were detected above odor threshold and predicted to contribute most effectively to odor intensity of urine incontinence.

    To investigate the correlation of major components of ocular astigmatism in myopic patients in an academic hospital. This cross-sectional study was conducted on 376 eyes of 188 patients who were referred to Farabi Eye Hospital for refractive surgery. Preoperative examinations including refraction and corneal topography were performed for all candidates to measure refractive and corneal astigmatism. Ocular residual astigmatism was calculated using vector analysis. Pearson's correlation and ANOVA analysis were used to evaluate the strength of the association between different types of astigmatism. Both eyes were defined as cluster and the Generalized Estimating Equations (GEE) analysis were performed. Mean age of 119 women (63.3%) and 69 men (36.7%) was 27.8 ± 5.7 years. Mean refractive error based on spherical equivalent was -3.59 ± 1.95D (range, -0.54 to -10.22D). Mean refractive and corneal astigmatism was 1.97 ± 1.3D and 1.85 ± 1.01D, respectively. Mean amount of ORA was 0.65 ± 0.36D.There was a significant correlation between ORA and refractive astigmatism(r=0.23, pcorrelation between ORA and corneal astigmatism (r=0.13, p=0.014). There was a significant correlation between J0 and J45 values of ORA and corneal astigmatism (pcorrelation between ORA and refractive astigmatism, refractive and corneal astigmatism and a weak correlation between ORA and corneal astigmatism in refractive surgery candidates. Identifying the type of astigmatism and preoperative measurement of ocular residual astigmatism is highly recommended prior to any refractive surgery, especially in cases with significant astigmatism.

    Research on how depression influences social decision making has been scarce. This study investigated how people with depression make decisions in an interpersonal trust-reciprocity game. Fifty female patients diagnosed with major depressive disorders (MDDs) and 49 healthy women participated in this study. The experiment was conducted on a one-to-one basis. Participants were asked to play the role of a trustee responsible for investing money given to them by an anonymous female investor playing on another computer station. In each trial, the investor would send to a participant (the trustee) a request for a certain percentage of the appreciated investment (repayment proportion). Since only the participant knew the exact amount of the appreciated investment, she could decide to pay more (altruistic act), the same, or less (deceptive act) than the requested amount. The participant's money acquired in the trial would be confiscated if her deceptive act was caught. The frequency of deceptive or altruistic decisions and relative monetary gain in each decision choice were examined. People with depression made fewer deceptive and fewer altruistic responses than healthy controls in all conditions. Moreover, the specific behavioral pattern presented by people with depression was modulated by the task factors, including the risk of deception detection and others' intentions (benevolence vs. malevolence). Findings of this study contribute to furthering our understanding of the specific pattern of social behavioral changes associated with depression.

    Thirty-seven patients with {beta}-thalassemia major, including 14 adolescents (15.2 {+-} 3.0 years) and 23 adults (26.4 {+-} 6.9 years), were studied. T2 relaxation time (T2) of the liver, bone marrow, pancreas and pituitary gland was measured in a 1.5-Tesla magnetic resonance (MR) imager, using a multiecho spin-echo sequence (TR/TE 2,000/20, 40, 60, 80, 100, 120, 140, 160 ms). Pituitary gland height was evaluated in a midline sagittal scan of a spin-echo sequence (TR/TE, 500/20 ms). The T2 of the pituitary gland was higher in adolescents (59.4 {+-} 15 ms) than in adults (45.3 {+-} 10.4 ms), P < 0.05. The T2 of the pancreas was lower in adolescents (43.6 {+-} 10.3 ms) than in adults (54.4 {+-} 10.4 ms). No difference among groups was found in the T2 of the liver and bone marrow. There was no significant correlation of the T2 among the liver, pancreas, pituitary gland and bone marrow. There was no significant correlation between serum ferritin and T2 of the liver, pancreas and bone marrow. Pituitary T2 showed a significant correlation with pituitary gland height (adolescents: R = 0.63, adults: R = 0.62, P < 0.05) and serum ferritin (adolescents: R = -0.60, adults: R = -0.50, P < 0.05). In conclusion, iron overload evaluated by T2 is organ specific. After adolescence, age-related T2 changes are predominantly associated with pituitary siderosis and fatty degeneration of the pancreas. Pituitary size decreases with progressing siderosis. (orig.)

    The study was carried out to evaluate endocrinal aspects of the pancreas in thalassemia children, ages 5 - 10 years maintained under either regular or irregular iron chelation therapy. A matched control on healthy children, was included for comparison. As regards laboratory findings, fasting and post prandial blood sugar was significantly elevated in thalassemia children than the control and serum insulin was significantly lower in the irregular iron chelation group than both in the regular one and in the control group. Most cases of diabetic thalassemia children clinically and biochemically were of irregular iron chelation and with older age. They were frequently higher transfused. There is significant rise of serum ferritin in diabetic group than in diabetic thalassemia children. In conclusion, pancreatic dysfunction can be detected in thalassemia children, but regular iron chelation can reduce its occurrence. 10 tabs.

    The aim of this study was to determine the molecular defects of heterozygous beta thalassaemia and to ascertain their distribution in Lanzarote. Molecular characterization was achieved by real time polymerase chain reaction (RT-PCR LightCycler, Roche), PCR-ARMS (PCR-amplification reaction mutations system) and DNA sequencing on an automated DNA sequencer. Two hundred forty-three heterozygous beta thalassaemia carriers were included between July 1991 and February 2007. RT-PCR detected the molecular defect in 81% of the beta thalassaemia chromosomes analyzed [113 codon CD 39 (C --> T); 41 IVS-1-nt-110 (G --> A), 25 IVS 1-nt-1 (G --> A) and 19 IVS 1-nt-6 (T --> C)]. The remaining 12 molecular defects included the deletion 619 bp (7.8%) and the mutations -28 (A --> G), IVS1-nt-2 (T --> G), CD 41/42 (-TTCT), CD 8/9 (+G), CD 51 (-C), CD 22 (G --> T) and CD 24 (T --> A), CD 67 (-TG) and the novel mutation CD 20/21-TGGA. The distribution of the mutations is similar to that found in the Mediterranean area. The increasing migratory flow received in the Canary Islands may explain the emergence of new mutations not reported before in our area.

    Cardiac complications are among the most serious problems of thalassemia intermedia patients. The current study was initiated to address the latter issue through the study of the echocardiographic findings and correlate it with clinical characteristics of thalassemia intermedia patients in Duhok, Kurdistan region, Iraq. An echocardiographic assessment of 61 beta-thalassemia intermedia cases was performed. It included 30 males and 31 females, with a mean age 19.6 ± 7.5 years. The standard echostudy of two-dimension and M-mode measurements of cardiac chambers were done. The continuous doppler regurgitant jet of tricuspid and pulmonary valves were recorded. Left ventricle diastolic function was assessed by pulsed doppler of mitral valve inflow. To correlate the clinical with echocardiographic findings, patients were divided, according to tricuspid regurgitant velocity, into three groups (intermedia patients. Therapeutic trails targeting these complications are indicated, and echocardiographic assessment is necessary to be offered early for thalassemia intermedia.

    Full Text Available Background: The development of anti-red blood cell antibodies (both allo-and autoantibodies remains a major problem in thalassemia major patients. We studied the frequency of red blood cell (RBC alloimmunization and autoimmunization among thalassemia patients who received regular transfusions at our center and analyzed the factors, which may be responsible for development of these antibodies. Materials and Methods: The study was carried out on 319 multiply transfused patients with β-thalassemia major registered with thalassemia clinic at our institute. Clinical and transfusion records of all the patients were examined for age of patients, age at initiation of transfusion therapy, total number of blood units transfused, transfusion interval, status of splenectomy or other interventions. Alloantibody screening and identification was done using three cell and 11 cell panel (Diapanel, Bio-rad, Switzerland respectively. To detect autoantibodies, autocontrol was carried out using polyspecific coombs (IgG + C3d gel cards. Results: Eighteen patients out of total 319 patients (5.64% developed alloantibodies and 90 (28.2% developed autoantibodies. Nine out of 18 patients with alloantibodies also had autoantibodies. Age at first transfusion was significantly higher in alloimmunized than non-immunized patients (P = 0.042. Out of 23 alloantibodies, 52.17% belonged to Rh blood group system (Anti-E = 17%, Anti D = 13%, Anti-C = 13%, Anti-C w = 9%, 35% belonged to Kell blood group system, 9% of Kidd and 4% of Xg blood group system. Conclusion: Alloimmunization was detected in 5.64% of multitransfused thalassemia patients. Rh and Kell blood group system antibodies accounted for more than 80% of alloantibodies. This study re-emphasizes the need for RBC antigen typing before first transfusion and issue of antigen matched blood (at least for Rh and Kell antigen. Early institution of transfusion therapy after diagnosis is another means of decreasing

    Full Text Available Determination of Rh, Kell, Duffy and Kidd phenotypes in addition to ABO is used to prevent the alloimmunization to red blood cells (RBCs antigens and as part of the antibody identification process in patients with beta Thalassemia. However, phenotyping in these patients can be time consuming and difficult to interpret. In these situations, it would be valuable to have an alternative to hemagglutination tests to determine the patient's antigen profile. We used PCR-RFLP to genotype such patients. DNA was prepared from 50 patients with beta Thalassemia who had been phenotyped by routine hemagglutination, and tested for Kell, Kidd, Duffy/GATA mutation by PCR-RFLP. RHD/non-D was analysed by PCR product size associated to RHD gene sequence in intron 4 and exon 10/3'UTR. The genotyping assays were performed without knowledge of phenotype results. For RHD/non-D, 47 were RhD+ and RHD+/RHCE+, and 3 were RhD- and RHD-/RHCE+. For Kell, 48 kk were K2K2 and 2 Kk were K1K2. For Duffy, of 44 samples that had normal GATA box, 8 Fy(a+b- were FYA/FYA, 15 Fy(a+b+ were FYB/FYB, and 19 Fy(a+b+ were FYA/FYB; of the other 4 samples 3 were FYA/FYB and heterozygous GATA mutation, and 1 Fy(a-b- was FYB/FYB, homozygous GATA mutation. Two samples phenotyped as Fy(a+b- that had normal GATA , presented the 265T/298A mutations and two samples phenotyped as Fy(a-b+ were genotyped was FYA/FYB.. For Kidd , 15 Jk(a+b were JKA/JKA, 12 Jk(a-b+ were JKB/JKB, and 20 Jk(a+b+ were JKA/JKB. Three samples phenotyped as JK(a+b+ were genotyped as JKB/JKB. Genotype is more accurate than phenotype for determination of blood groups in polytransfused patients with betaThalassemia. Genotyping in these patients can be helpful to select antigen-negative RBCs for transfusion.

    It is known that a blood transfusion is necessary for survival in patients with thalassemia, but it may cause myocardial dysfunction due to myocardial siderosis as in other organs. The aim of this study was to evaluate myocardial perfusion by means of stress thallium scanning (MPS) and left ventricular functions by rest radionuclide ventriculography (RNV). Twenty-one patients at ages 9-16 (mean 12.1±3.2) who have been diagnosed with thalassemia for 4-15 years mean 12.7±4.8) were included in the study. They had blood transfusion 78-318 times (mean 162.1±71). MPS and RNV was performed within two days after the any transfusion. MPS showed ischemia in 3 patients and normal perfusion in 18 patients. RNV revealed normal systolic parameters (wall motion, EF, PER, TPE) but diminished diastolic parameters (TPF, PFR) compared with normal values (p<0.05). We conclude that ischemia or fixed defects may be seen in stress MPS as results of cardiac involvement in patients with thalassemia. But, RNV is an important and preferable test for the early detection of subclinic cardiomyopathy. RNV may therefore show diastolic abnormalities before the systolic abnormalities show up. (author)

    It is known that a blood transfusion is necessary for survival in patients with thalassemia, but it may cause myocardial dysfunction due to myocardial siderosis as in other organs. The aim of this study was to evaluate myocardial perfusion by means of stress thallium scanning (MPS) and left ventricular functions by rest radionuclide ventriculography (RNV). Twenty-one patients at ages 9-16 (mean 12.1{+-}3.2) who have been diagnosed with thalassemia for 4-15 years mean 12.7{+-}4.8) were included in the study. They had blood transfusion 78-318 times (mean 162.1{+-}71). MPS and RNV was performed within two days after the any transfusion. MPS showed ischemia in 3 patients and normal perfusion in 18 patients. RNV revealed normal systolic parameters (wall motion, EF, PER, TPE) but diminished diastolic parameters (TPF, PFR) compared with normal values (p<0.05). We conclude that ischemia or fixed defects may be seen in stress MPS as results of cardiac involvement in patients with thalassemia. But, RNV is an important and preferable test for the early detection of subclinic cardiomyopathy. RNV may therefore show diastolic abnormalities before the systolic abnormalities show up. (author)

    The presumed safety of paracetamol in high-cardiovascular risk patients has been questioned. We determined whether paracetamol or ibuprofen use is associated with major cardiovascular events (MACE) or major bleeding in 19 120 patients with recent ischemic stroke or transient ischemic attack of mainly atherothrombotic origin included in the Prevention of cerebrovascular and cardiovascular events of ischemic origin with terutroban in patients with a history of ischemic stroke or transient ischemic attack (PERFORM) trial. We performed 2 nested case-control analysis (2153 cases with MACE during trial follow-up and 4306 controls matched on Essen stroke risk score; 809 cases with major bleeding matched with 1616 controls) and a separate time-varying analysis. 12.3% were prescribed paracetamol and 2.5% ibuprofen. Median duration of treatment was 14 (interquartile range 5-145) days for paracetamol and 9 (5-30) days for ibuprofen. Paracetamol, but not ibuprofen, was associated with increased risk of MACE (odds ratio 1.21, 95% confidence interval [CI] 1.04-1.42) or a major bleeding (odds ratio 1.60, 95% CI 1.26-2.03), with no impact of daily dose and duration of paracetamol treatment. Time-varying analysis found an increased risk of MACE with both paracetamol (hazard ratio 1.22, 95% CI 1.05-1.43) and ibuprofen (hazard ratio 1.47, 95% CI 1.06-2.03) and of major bleeding with paracetamol (hazard ratio 1.95, 95% CI 1.45-2.62). There was a weak and inconsistent signal for association between paracetamol or ibuprofen and MACE or major bleeding, which may be related to either a genuine but modest effect of these drugs or to residual confounding. http://www.isrctn.com.

    Elephantiasis nostras verrucosa is a rare condition characterised by papules, verrucous lesions, fibrosis and deformity of the affected area. It is caused by chronic lymphedema that could be congenital or produced by a non-associated infection (such as tuberculosis, mycotic infection, syphilis), surgery, radiotherapy, trauma, neoplastic obstruction, obesity, portal hypertension, or congestive heart failure. There is no standard treatment for this rare skin disorder. Depending on the cause and the severity, the treatment can be medical or surgical. We report the case of a man seen in our hospital with a major depression and elephantiasis nostras verrucosa skin lesions on both legs, who was successfully treated with surgical debridement and conservative measures.

    Beta thalassemia major (BTM) and its treatment by hematopoietic stem cell transplantation (HSCT) may have deleterious effects on the endocrine systems. We assessed endocrine complications of HSCT in pediatric patients for 3 months. In 20 (6 female) pediatric major thalassemic patients (mean age of 10.8 ± 3.9 years old), prolactin, luteinizing hormone (LH), follicle-stimulating hormone (FSH), T4, T3, thyroid-stimulating hormone (TSH), IGF-1, testosterone (in males) or estradiol (in females) were measured as a batch at the Endocrinology and Metabolism Research Center (EMRC) of Tehran University of Medical Sciences (TUMS) laboratories before HSCT and 1 and 3 months afterwards. The cosyntropin test for all and the clonidine test for short stature patients was conducted before HSCT. Before HSCT, delayed puberty and hypogonadotropic hypogonadism was found in 10% and 20% of patients, respectively. GH deficiency, low IGF1 and short stature was found in 25%, 55% and 40% of patients, respectively. Hypocortisolism, hypothyroidism and panhypopituitarism was found in 15%, 10% and 15% of patients, respectively. Prevalence of hypogonadotropic hypogonadism, low IGF1, hypothyroidism and panhypopituitarism was found in 20%, 40%, 10% and 10% of patients after 3 months, respectively (delayed puberty and short stature prevalence do not change after 3 months). HSCT caused lower T3 and estradiol and higher TSH. Corticosteroid users (15) had higher GH and lower T3 and testosterone or estradiol. Ferritin had a significant (negative) correlation with (before) prolactin and a significant correlation with T3 and T4 after HSCT. Age and acute graft-versus-host disease (GVHD) had no significant effect. Considering the small sample size and short duration of the study, it is difficult to reach any conclusion however it seems HSCT does not appear to have an overall positive or negative effect on prevalence of pituitary- hypothalamus axis disorders in pediatric thalassemic patients in 3 months.

    Abstract Major depressive disorder is an often chronic and recurring illness. Left untreated, major depressive disorder may result in progressive alterations in brain morphometry and circuit function. Recent findings, however, suggest that pharmacotherapy may halt and possibly reverse those effects. These findings, together with evidence that a delay in treatment is associated with poorer clinical outcomes, underscore the urgency of rapidly treating depression to full recovery. Early optimized treatment, using measurement-based care and customizing treatment to the individual patient, may afford the best possible outcomes for each patient. The aim of this article is to present recommendations for using a patient-centered approach to rapidly provide optimal pharmacological treatment to patients with major depressive disorder. Offering major depressive disorder treatment determined by individual patient characteristics (e.g., predominant symptoms, medical history, comorbidities), patient preferences and expectations, and, critically, their own definition of wellness provides the best opportunity for full functional recovery.

  16. Molecular characterization of hemoglobin D Punjab traits and clinical-hematological profile of the patients

    Directory of Open Access Journals (Sweden)

    Sanjay Pandey

    Full Text Available CONTEXT AND OBJECTIVE: Hemoglobin (Hb D hemoglobinopathies are widespread diseases in northwestern India and usually present with mild hemolytic anemia and mild to moderate splenomegaly. The heterozygous form of Hb D is clinically silent, but coinheritance of Hb D with Hb S or beta-thalassemia produces clinically significant conditions like thalassemia intermedia of moderate severity. Under heterozygous conditions with coinheritance of alpha and beta-thalassemia, patients show a degree of clinical variability. Thus, our aim was to molecularly characterize the Hb D trait among individuals who were clinically symptomatic because of co-inheritance of alpha deletions or any beta-globin gene mutations. DESIGN AND SETTING: This was a cross-sectional study conducted in an autonomous tertiary-care hospital. METHODS: Complete blood count and red cell indices were measured using an automated cell analyzer. Quantitative assessment of hemoglobin Hb F, Hb A, Hb A2 and Hb D was performed by means of high performance liquid chromatography (HPLC. DNA extraction was done using the phenol-chloroform method. Molecular analyses on common alpha deletions and common beta mutations were done using the Gap polymerase chain reaction and Amplification Refractory Mutation System, respectively. RESULTS: We evaluated 30 patients and found clinical variation in the behavior of Hb D traits. In six patients, the Hb D traits were clinically symptomatic and behaved like those of thalassemia intermedia. Molecular characterization showed that three out of these six were IVS-1-5 positive. CONCLUSIONS: HPLC may not be the gold standard for diagnosing symptomatic Hb D Punjab traits. Hence, standard confirmation should include molecular studies.

    Nonoperative management (NOM) of blunt splenic injuries has been widely accepted, and the application of splenic artery embolization (SAE) has become an effective adjunct to NOM. However, complications do occur after SAE. In this study, we assess the factors leading to the major complications associated with SAE. Focusing on the major complications after SAE, we retrospectively studied patients who received SAE and were admitted to 2 major referral trauma centers under the same established algorithm for management of blunt splenic injuries. The demographics, angiographic findings, and factors for major complications after SAE were examined. Major complications were considered to be direct adverse effects arising from SAE that were potentially fatal or were capable of causing disability. There were a total of 261 patients with blunt splenic injuries in this study. Of the 261 patients, 53 underwent SAE, 11 (21%) of whom were noted to have 12 major complications: 8 cases of postprocedural bleeding, 2 cases of total infarction, 1 case of splenic abscess, and 1 case of splenic atrophy. Patients older than 65 years were more susceptible to major complications after SAE. Splenic artery embolization is considered an effective adjunct to NOM in patients with blunt splenic injuries. However, risks of major complications do exist, and being elderly is, in part, associated with a higher major complication incidence. Copyright © 2011 Elsevier Inc. All rights reserved.

    To study the association between the epidermal growth factor (EGF) gene and intelligence in patients with major depression. Intelligence measurement using Wechsler Adult Intelligence Scale (WAIS) was performed on 120 unrelated patients with major depression and 46 control subjects. Blood was collected from all subjects for extraction of genomic DNA. Four single nucleotide polymorphisms (SNPs) in the EGF gene were genotyped using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI- TOF-MS). Mean scores of both score lang and score task, two subtests in WAIS, differed significantly between major depression patients and controls (Pintelligence in patients with major depression. Genetic variation in the EGF gene may increase the susceptibility of major depression.

    We sought to determine whether patient-provider gender concordance influences the detection and care of depression and comorbid anxiety and substance use in patients with major depression Cross-sectional analyses of baseline patient survey data linked with provider data were performed. Data based on routine primary care visits in clinics from a variety of health systems serving diverse patient populations across the United States. Participants all had major depression. Depression care was examined in the Quality Improvement for Depression (QID) Collaboration sample (n patients = 1,428, n providers = 389). In a subanalysis of data solely from 714 patients and 157 providers from Partners-In-Care, one of the projects participating in QID, we also examined detection of anxiety disorder and alcohol or drug problems. Rates of detection and care of mental health problems in primary care were low even among patients with major depression. Except for anxiety counseling in female patients, patient-provider gender concordance did not improve care as hypothesized. However, female providers were more likely to counsel on anxiety and less likely to counsel on alcohol or drug use than male providers. Female patients were less likely to be counseled on alcohol or drug use compared with male patients. Detection and care of mental health and substance use problems for patients with major depression is not influenced by patient-provider gender concordance. However, depressed female patients may have greater unmet needs for alcohol and drug use counseling than their male counterparts.

    Routine primary care data are increasingly being used for evaluation and research purposes but there are concerns about the completeness and accuracy of diagnoses and events captured in such databases. We evaluated how well patients with major cardiovascular disease (CVD) can be identified using primary care morbidity data and drug prescriptions. The study was conducted using data from 17,230 diabetes patients of the GIANTT database and Dutch Hospital Data register. To estimate the accuracy of the different measures, we analyzed the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) relative to hospitalizations and/or records with a diagnosis indicating major CVD, including ischaemic heart diseases and cerebrovascular events. Using primary care morbidity data, 43% of major CVD hospitalizations could be identified. Adding drug prescriptions to the search increased the sensitivity up to 94%. A proxy of at least one prescription of either a platelet aggregation inhibitor, vitamin k antagonist or nitrate could identify 85% of patients with a history of major CVD recorded in primary care, with an NPV of 97%. Using the same proxy, 57% of incident major CVD recorded in primary or hospital care could be identified, with an NPV of 99%. A substantial proportion of major CVD hospitalizations was not recorded in primary care morbidity data. Drug prescriptions can be used in addition to diagnosis codes to identify more patients with major CVD, and also to identify patients without a history of major CVD.

    This study explored the effect of a first aid model employing two nurses on the efficient rescue operation time and the efficient resuscitation time for major burn patients. A two-nurse model of first aid was designed for major burn patients. The model includes a division of labor between the first aid nurses and the re-organization of emergency carts. The clinical effectiveness of the process was examined in a retrospective chart review of 156 cases of major burn patients, experiencing shock and low blood volume, who were admitted to the intensive care unit of the department of burn surgery between November 2009 and June 2013. Of the 156 major burn cases, 87 patients who received first aid using the double personnel model were assigned to the test group and the 69 patients who received first aid using the standard first aid model were assigned to the control group. The efficient rescue operation time and the efficient resuscitation time for the patients were compared between the two groups. Student's t tests were used to the compare the mean difference between the groups. Statistically significant differences between the two groups were found on both measures (P's first aid model based on scientifically validated procedures and a reasonable division of labor can shorten the efficient rescue operation time and the efficient resuscitation time for major burn patients. Given these findings, the model appears to be worthy of clinical application.

    Objective: To study the MRI volume of the amygdala and hippocampus in patients with major depression. Methods: Quantitative MRI of the amygdala and hippocampus was studied in 22 patients with major depression and compared with 13 age-matched controls. Results: Both groups exhibited similar significant hippocampal asymmetry (left smaller than right). The volume of the bilateral hippocampus was significantly smaller in the patient group than that in the controls (left: t=9.96, P<0.01; right: t=11.88, P<0.01). The right amygdala was smaller in the patient group than that in the control group (t=5.50, P<0.01), No correlation was found between the hippocampal volume abnormalities and the course of disease. Conclusion: These findings support the hypothesis that the hippocampus and amygdala within limbic-cortical networks may play a crucial role in the pathogenesis of major depression. (authors)

    Major depressive disorder (MDD) is often associated with dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis by chronic stress. In comparison, psychosocial stress-induced activation of salivary α-amylase (sAA) functions as a marker of sympathoadrenal medullary system (SAM) activity. However, in contrast to salivary cortisol, sAA has been less extensively studied in MDD patients. The present study measured sAA and salivary cortisol levels in patients with MDD. The authors determined Profile of Mood State (POMS) and State-Trait anxiety Inventory (STAI) scores, Heart Rate Variability (HRV), and sAA and salivary cortisol levels in 88 patients with MDD and 41 healthy volunteers following the application of electrical stimulation stress. Patients with major depressive disorder were 8 points or more on Hamilton Depression Scale (HAM-D) scores. Tension-Anxiety, Depression-Dejection, Anger-Hostility, Fatigue, and Confusion scores in patients with major depressive disorder were significantly increased compared to healthy controls. In contrast, Vigor scores in patients with MDD were significantly decreased compared with healthy controls. There was no difference in heart rate variability measures between MDD patients and healthy controls. The threshold of electrical stimulation applied in MDD patients was lower than that in healthy controls. SAA levels in female MDD patients were significantly elevated relative to controls both before and after electrical stimulation. Finally, there were no differences in salivary cortisol levels between major depressive patients and controls. In the present study only three time points were explored. Furthermore, the increased secretion of sAA before and after stimulation could allude to an increased responsiveness of novel and uncontrollable situations in patients with MDD. These preliminary results suggest that sAA might be a useful biological marker of MDD. Copyright © 2011 Elsevier Inc. All rights reserved.

  11. The portfolio method as management support for patients with major depression.

    2014-06-01

    To describe how patients with major depression in psychiatric outpatient care use the portfolio method and whether the method helps the patients to understand their depression. Major depressive disorder is an increasing problem in society. Learning about one's depression has been demonstrated to be important for recovery. If the goal is better understanding and management of depression, learning must proceed on the patient's own terms, based on the patient's previous understanding of their depression. Learning must be aligned with patient needs if it is to result in meaningful and useful understanding. Each patient's portfolio consisted of a binder. Inside the binder, there was a register with predetermined flaps and questions. The patients were asked to work with the questions in the sections that built the content in the portfolio. Individual interviews with patients (n = 5) suffering from major depression according to Diagnostic and Statistical Manual of Mental Disorders - Fourth Edition (DSM-IV) (American Psychiatric Association 1994) were repeatedly conducted between April 2008 and August 2009 in two psychiatric outpatient clinics in western Sweden. Data were analysed using latent content analysis. The results showed that the portfolio was used by patients as a management strategy for processing and analysis of their situation and that a portfolio's structure affects its usability. The patients use the portfolio for reflection on and confirmation of their progress, to create structure in their situation, as a management strategy for remembering situations and providing reminders of upcoming activities. Using a clearly structured care portfolio can enable participation and patient learning and help patients understand their depression. The portfolio method could provide a tool in psychiatric nursing that may facilitate patient understanding and increase self-efficacy. © 2013 John Wiley & Sons Ltd.

    Full Text Available Abstract Background The fibromyalgia syndrome (FMS is suggested to be a manifestation of depression or affective spectrum disorder. We measured the cognitive style of patients with FMS to assess personality styles in 44 patients with fibromyalgia syndrome (FMS by comparing them with 43 patients with major depressive disorder (MDD and 41 healthy controls (HC. Methods Personality styles were measured by the Sociotropy and Autonomy Scale (SAS and the Dysfunctional Attitude Scale (DAS. The Structured Clinical interview for DSM Axis I was applied to Axis I disorders, while the Beck Depression Inventory was used to measure depression severity. Results Patients with FMS in general have a sociotropic personality style similar to patients with MDD, and different from HC, but FMS patients without a lifetime history of MDD had a cognitive personality style different from patients with MDD and similar to HC. Conclusion These findings suggest that a depressotypic personality style is related to depressive disorder, but not to FMS.

  14. Neural mechanisms of reinforcement learning in unmedicated patients with major depressive disorder.

    2017-04-01

    According to current concepts, major depressive disorder is strongly related to dysfunctional neural processing of motivational information, entailing impairments in reinforcement learning. While computational modelling can reveal the precise nature of neural learning signals, it has not been used to study learning-related neural dysfunctions in unmedicated patients with major depressive disorder so far. We thus aimed at comparing the neural coding of reward and punishment prediction errors, representing indicators of neural learning-related processes, between unmedicated patients with major depressive disorder and healthy participants. To this end, a group of unmedicated patients with major depressive disorder (n = 28) and a group of age- and sex-matched healthy control participants (n = 30) completed an instrumental learning task involving monetary gains and losses during functional magnetic resonance imaging. The two groups did not differ in their learning performance. Patients and control participants showed the same level of prediction error-related activity in the ventral striatum and the anterior insula. In contrast, neural coding of reward prediction errors in the medial orbitofrontal cortex was reduced in patients. Moreover, neural reward prediction error signals in the medial orbitofrontal cortex and ventral striatum showed negative correlations with anhedonia severity. Using a standard instrumental learning paradigm we found no evidence for an overall impairment of reinforcement learning in medication-free patients with major depressive disorder. Importantly, however, the attenuated neural coding of reward in the medial orbitofrontal cortex and the relation between anhedonia and reduced reward prediction error-signalling in the medial orbitofrontal cortex and ventral striatum likely reflect an impairment in experiencing pleasure from rewarding events as a key mechanism of anhedonia in major depressive disorder. © The Author (2017).

    Background Major depressive disorder is a serious psychiatric illness with a highly variable and heterogeneous clinical course. Due to the lack of consistent data from previous studies, the study of morphometric changes in major depressive disorder is still a major point of research requiring additional studies. The aim of the study presented here was to characterize and quantify regional gray matter abnormalities in a large sample of clinically well-characterized patients with major depressive disorder. Methods For this study one-hundred thirty two patients with major depressive disorder and 132 age- and gender-matched healthy control participants were included, 35 with their first episode and 97 with recurrent depression. To analyse gray matter abnormalities, voxel-based morphometry (VBM8) was employed on T1 weighted MRI data. We performed whole-brain analyses as well as a region-of-interest approach on the hippocampal formation, anterior cingulate cortex and amygdala, correlating the number of depressive episodes. Results Compared to healthy control persons, patients showed a strong gray-matter reduction in the right anterior insula. In addition, region-of-interest analyses revealed significant gray-matter reductions in the hippocampal formation. The observed alterations were more severe in patients with recurrent depressive episodes than in patients with a first episode. The number of depressive episodes was negatively correlated with gray-matter volume in the right hippocampus and right amygdala. Conclusions The anterior insula gray matter structure appears to be strongly affected in major depressive disorder and might play an important role in the neurobiology of depression. The hippocampal and amygdala volume loss cumulating with the number of episodes might be explained either by repeated neurotoxic stress or alternatively by higher relapse rates in patients showing hippocampal atrophy.

    The aim of this study was to identify the most-feared complications of diabetes mellitus (DM), comparing those with diabetic foot pathology with those without diabetic foot pathology. We determined the frequency of patients ranking major lower-extremity amputation (LEA) as their greatest fear in comparison to blindness, death, diabetic foot infection (DFI), or end-stage renal disease (ESRD) requiring dialysis. We further categorized the study group patients (N = 207) by their pathology such as diabetic foot ulcer (DFU), Charcot neuroarthropathy, foot infection, or acute neuropathic fractures and dislocations. The control group (N = 254) was comprised of patients with diabetes who presented with common non-diabetes-related foot pathology. A total of 461 patients were enrolled in this study and included 254 patients without diabetic foot complications and 207 patients with diabetic foot problems. When comparing patients with and without diabetic disease, no significant differences were observed with regard to their fear of blindness, DFI, or ESRD requiring dialysis. Patients with diabetic foot disease (61 of 207, 31.9%) were 136% more likely (odds ratio [OR] = 2.36; 95% CI = 1.51-3.70; P = .002] to rank major LEA as their greatest fear when compared with diabetic patients without foot disease (42 of 254, 16.5%) and were 49% less likely (OR = 0.51; 95% CI = 0.34-0.79; P = .002) to rank death as their greatest fear compared with patients without diabetic foot disease. Patients with diabetic foot pathology fear major LEA more than death, foot infection, or ESRD. Variables that were associated with ranking LEA as the greatest fear were the presence of a diabetic-related foot complication, duration of DM ≥10 years, insulin use, and the presence of peripheral neuropathy.

    Full Text Available Background and Objectives: Todays, evaluation of the relationship between thyroid function and some psychiatric diseases have been identified. However, studies on the relationship between thyroid function and suicide attempt are limited. The present study was carried out with the aim of evaluating thyroid function in patients attempting suicide. Methods: In this descriptive analytical study during the years 2011 and 2012, 88 patients with major depression and recent history of suicide attemp and 89 patients with major depression without history of recent suicide, who were hospitalized in the psychiatric ward of Hazrat Rasoul Akram Hospital in Tehran, were included in the study. The studied variables in this research included demographic variables, such as age, gender as well as clinical findings, such as thyroid function tests, including TSH, T3, T4. thyroid function tests were requested for patients when hospitalized with a diagnosis of major depression during the years 2011 and 2012, that these values were extracted from the patients’ medical records. Results: The two groups were matched in terms of age and gender. In patients with recent suicide attempt, 5 (5.6% cases of clinical hypothyroidism and 6 (6.8% cases of subclinical hypothyroidism, were reported. In the major depression patients without recent suicide attempt, there were 3 (3.3% cases of clinical hypothyroidism and 6 (6.7% cases of subclinical hypothyroidism, and the two groups had no significant difference in terms of the incidence of thyroid disease (p=0.75. Conclusion: According to the results of the present study, lower levels of T3 and T3 to T4 ratio can be one of the factors related to the recent history of suicide in patients with major depression.

    The objective of this study was to determine whether factors associated with depression differ between elderly residents of rural and urban areas. The research design was cross-sectional and observational. The study subjects consisted of 926 Medicare primary care patients (650 urban and 276 rural) who were age 65+ and cognitively intact and had enrolled in a randomized, controlled Medicare demonstration. Major depression was identified by the Mini International Neuropsychiatric Interview. A logistic regression model was estimated that included a rural-urban indicator variable, additional independent variables, and interaction terms between the rural-urban indicator and independent variables that were significant at p Reporting 0-1 close friends (odds ratio [OR]: 6.86; 95% confidence interval [CI]: 2.18-21.58), 2+ emergency room visits during the past 6 months (OR: 4.00; 95% CI: 1.19-13.43), and more financial strain (OR: 1.50; 95% CI: 1.01-2.23) were associated with significantly higher likelihood of major depression among rural as compared with urban patients. The SF-36 Physical Component Summary score had a curvilinear relationship with major depression and was higher for urban patients. The predicted probability for major depression is lower for the rural patients when financial strain is low, about the same for rural and urban patients when strain is intermediate, and higher for rural patients when strain is high. Clinicians in rural areas should be vigilant for major depression among patients with very few close friends, several recent emergency department visits, and financial strain.

    BACKGROUND: The manifestation of major depressive disorder (MDD) may include cognitive symptoms that can precede the onset of MDD and persist beyond the resolution of acute depressive episodes. However, little is known about how cognitive symptoms are experienced by MDD patients and the people...... symptoms in MDD appeared to negatively impact patients' social relationships and patients' ability to handle daily tasks at work and at home; (3) patients' cognitive symptoms also impacted relationships with family members and coworkers; (4) patients' cognitive symptoms increased stress and feelings...... of failure, which in turn seemed to worsen the cognitive symptoms, thereby creating a destructive cycle; and (5) although HCPs recommended that patients re-engage in everyday activities to help overcome their depression, cognitive symptoms seemed to impede such functional recovery. CONCLUSIONS: Taken...

    Full Text Available Background: Electroconvulsive therapy (ECT is utilized for treatment of a range of psychiatric disorders including major depressive disorder (MDD. One of the major complications in using ECT is cardiovascular problems i.e., bradycardia. The present study was designed to investigate the effect of atropine on the pulse rate (PR of the patients under treatment with ECT. Materials and Methods: In this randomized clinical trial, 30 patients with diagnosis of MDD who received atropine before ECT treatment (control group were compared with 30 patients with the same diagnosis without receiving atropine (experimental group under ECT treatment. Both groups received ECT under the same term and condition. The PR of the patients were recorded 7 times (twice before anesthesia and ECT and 5 fixed one min intervals immediately after receiving ECT; for 10 sessions of treatment with ECT (3 times a week. The results were analyzed using repeated measure analysis of variance. The PR under 50 was the cut off point for differentiating the patients suffering from bradycardia and those without it. Results: Slight increment in PRs for experimental group (patient who did not receive atropine in contrast to control group were observed, but it did not reach a statistically significant level. The gender (male/female did not have different PR. The age of the patients and initial PR (regarded as co-variances did not show significant effect on PR for total sample. Conclusion: There seems to be not necessary to use atropine treatment for depressed patients receiving ECT.

    The current study used a descriptive correlational design to examine the relationship between mindfulness and quality of life (QOL) among patients with schizophrenia (n = 160) and patients with major depressive disorder (MDD) (n = 161), controlling for demographic and clinical variables. Participants completed self-reported questionnaires regarding demographic variables, severity of depression, QOL, and mindfulness. Patients diagnosed with MDD had higher mindfulness scores than patients diagnosed with schizophrenia. Mindfulness scores were significantly associated with the severity of depression among participants. After controlling for the demographic variables and severity of depressive symptoms, mindfulness had a unique variance in QOL among patients with schizophrenia, but not among patients with MDD. The current study provides preliminary evidence regarding the role of mindfulness in improving depressive symptoms and the overall QOL among patients diagnosed with mental illness.

    Full Text Available In this retrospective of electroencephalograms were to identify a surrogate biomarker for the Dopamine D2 receptors in the brain by comparing patients diagnosed with Schizophrenia taking Atypical Antipsychotics to Depressive patients medicated with Selective Serotonin Reuptake Inhibitors. To achieve this, thirty-seconds of resting EEG were spectrally transformed in sLORETA. Three-dimensional statistical non-paramentric maps (SnPM for the sLORETA Global Field Power within each band were then computed. Our results illustrated that the Right Superior Frontal Gyrus (t=2.049, p=0.007, along the dopamine mesolimbic pathway, had higher neuronal oscillations in the delta frequency band in the 100 Schizophrenia patients as compared to the 32-depressive female patients. The comparisons with both the 48 depressive patient cohort or the sixteen male depressive patient cohort did not yield any statistically significant findings. We conclude that the Superior Frontal Gyrus should be investigated as a possible surrogate biomarker for preclinical and clinical drug discovery in neuropharmacology.

    Depression is frequently observed in patients with systemic lupus erythematosus (SLE). Neuropsychiatric SLE (NPSLE) patients often exhibit cerebral hypometabolism, but the association between cerebral metabolism and depression remains unclear. To elucidate the features of cerebral metabolism in SLE patients with depression, we performed brain 18F-fluoro-d-glucose positron emission tomography (FDG-PET) on SLE patients with and without major depressive disorder. We performed brain FDG-PET on 20 SLE subjects (5 male, 15 female). The subjects were divided into two groups: subjects with major depressive disorder (DSLE) and subjects without major depressive disorder (non-DSLE). Cerebral glucose metabolism was analyzed using the three-dimensional stereotactic surface projection (3D-SSP) program. Regional metabolism was evaluated by stereotactic extraction estimation (SEE), in which the whole brain was divided into segments. Every SLE subject exhibited cerebral hypometabolism, in contrast to the normal healthy subjects. Regional analysis revealed a significantly lower ER in the left medial frontal gyrus (p=0.0055) and the right medial frontal gyrus (p=0.0022) in the DSLE group than in the non-DSLE group. Hypometabolism in the medial frontal gyrus may be related to major depressive disorder in SLE. Larger studies are needed to clarify this relationship. Copyright © 2017 Elsevier B.V.

    to evaluate whether bacterial genus is a risk factor for major amputation in patients with diabetic foot and infected ulcer. we conducted a case-control, observational study of 189 patients with infected ulcers in diabetic feet admitted to the Vascular Surgery Service of the Risoleta Tolentino Neves Hospital, from January 2007 to December 2012. The bacteriological evaluation was performed in deep tissue cultures from the lesions and amputation was considered major when performed above the foot'smiddle tarsus. the patients'mean age was 61.9±12.7 years; 122 (64.6%) were men. The cultures were positive in 86.8%, being monomicrobial in 72% of the cases. In patients with major amputation, Acinetobacter spp. (24.4%), Morganella spp. (24.4%), Proteus spp. (23.1%) and Enterococcus spp. (19.2%) were the most frequent types of bacteria. The most commonly isolated species were Acinetobacter baumannii, Morganella morganii, Pseudomonas aeruginosa and Proteus mirabilis. As predictors of major amputation, we identified the isolation of the generaAcinetobacter spp. and Klebsiella spp., serum creatinine ≥1.3mg/dl and hemoglobin creatinina ≥1,3mg/dl e de hemoglobina <11g/dl. os gêneros bacterianos Acinetobacter spp. e Klebsiella spp. identificados nas úlceras infectadas dos pacientes com pé diabético associaram-se a maior incidência de amputação maior.

    Full Text Available Background: Stainless steel wiring remains the most popular technique for primary sternal closure. Recently, a multifilament cable wiring system (Pioneer Surgical Technology Inc., Marquette, MI, USA was introduced for sternal closure and has gained wide acceptance due to its superior resistance to tension. We aimed to compare conventional steel wiring to multifilament cable fixation for sternal closure in patients undergoing major cardiac surgery. Methods: Data were collected retrospectively on 1,354 patients who underwent sternal closure after major cardiac surgery, using either the multifilament cable wiring system or conventional steel wires between January 2009 and October 2010. The surgical outcomes of these two groups of patients were compared using propensity score matching based on 18 baseline patient characteristics. Results: Propensity score matching yielded 392 pairs of patients in the two groups whose baseline profiles showed no significant differences. No significant differences between the two groups were observed in the rates of early mortality (2.0% vs. 1.3%, p=0.578, major wound complications requiring reconstruction (1.3% vs. 1.3%, p>0.99, minor wound complications (3.6% vs. 2.0%, p=0.279, or mediastinitis (0.8% vs. 1.0%, p=1.00. Patients in the multifilament cable group had fewer sternal bleeding events than those in the conventional wire group, but this tendency was not statistically significant (4.3% vs. 7.4%, p=0.068. Conclusion: The surgical outcomes of sternal closure using multifilament cable wires were comparable to those observed when conventional steel wires were used. Therefore, the multifilament cable wiring system may be considered a viable option for sternal closure in patients undergoing major cardiac surgery.

    Propofol pharmacokinetics were examined in 17 adults with major burns during the hyperdynamic convalescent phase. Eighteen nonburned surgical patients served as controls. After a 2-mg/kg intravenous dose of propofol, blood samples were collected at multiple time points. Noncompartmental methods were used to calculate the pharmacokinetic parameters. The following indices were higher in burns than controls: propofol clearance (64+/-17 vs 29+/-4 mL/kg/min, Pclearance of propofol in burned patients may imply that these patients require higher doses or infusion rates of propofol to attain a target plasma concentration or pharmacodynamic effect.

Place and Duration of Study:PIMS and NORI Hospital between July to September 2016. Methodology:A sample of 100 cancer patients participated in the study. The patients fulfilling the inclusion criteria were given a written consent form. Event related Rumination Inventory and WHO Quality of Life-Bref scale was used for data collection. Results:There were 57 male and 43 female patients within the age range of 18 to 66 years (mean = 36.62 +13.77 years). A significant negative correlation was found between intrusive rumination and all domains of quality of life as physical (r = -0.28, p<0.01), psychological (r = -0.19, p<0.01), social (r = -0.20, p<0.01), environmental (r = -0.17, p<0.05), and global (r = -0.26, p<0.01) functioning. Furthermore, results on regression analysis showed the significant prediction of the intrusive rumination on all domains of quality of life. The effect of deliberate rumination was found to be non-significant. Conclusion:Intrusive rumination significantly negatively predicted all domains of quality of life, whereas, quality of life of cancer patients was not significantly predicated by deliberate rumination.

    To gain insight into nurses' knowledge and attitudes regarding major immobility complications (pressure ulcers, pneumonia, deep vein thrombosis and urinary tract infections) and explore the correlation of nurses' knowledge and attitudes with the incidence of these complications. Immobility complications have adverse consequences, and effective management requires appropriate knowledge, attitudes and skills. Evidence about nurses' knowledge and attitudes regarding immobility complications is lacking. Cross-sectional study. A total of 3,903 nurses and 21,333 bedridden patients from 25 hospitals in China were surveyed. Nurses' knowledge and attitudes regarding major immobility complications were assessed using researcher-developed questionnaires. The content validity, reliability and internal consistency of the questionnaires were validated through expert review and a pilot study. The incidence of major immobility complications among bedridden patients from selected wards was surveyed by trained investigators. Correlations between knowledge, attitudes and the incidence of major immobility complications were evaluated with multilevel regression models. Mean knowledge scores were 64.07% for pressure ulcers, 72.92% for deep vein thrombosis, 76.54% for pneumonia and 83.30% for urinary tract infections. Mean attitude scores for these complications were 86.25%, 84.31%, 85.00% and 84.53%, respectively. Knowledge and attitude scores were significantly higher among nurses with older age, longer employment duration, higher education level, previous training experience and those working in tertiary hospitals or critical care units. Nurses' knowledge about pressure ulcers was negatively related to the incidence of pressure ulcers, and attitude towards pneumonia was negatively correlated with the incidence of pneumonia. Clinical nurses have relatively positive attitudes but inadequate knowledge regarding major immobility complications. Improved knowledge and attitudes regarding

    Full Text Available Objective: Stable mixed chimerism (MC may result in cure for thalassemia major patients following hematopoietic stem cell transplantation (HSCT, but rejection can occur. Twenty-eight HSCTs for thalassemia major were reviewed retrospectively to evaluate the clinical course of MC with possible risk factors and predictors of outcome, with a median follow-up of 1669 days (811-3576 days. Materials and Methods: Chimerism was detected by fluorescence in situ hybridization (FISH or multiplex polymerase chain reaction depending on the sex match between the donor and the recipient. Results: Primary rejection, stable MC and full donor chimerism was detected in 3.6%, 17.8% and 78.6% of patients, respectively. Clinically, 4/5 patients with stable MC had thalassemia trait with donor chimerism as low as 14%. One patient was started on pRBC transfusions at 2.5 years postHSCT. Conclusion: Stable MC can result in cure for thalassemia major patients. The clinical picture remains as the best guide for intervention until a more reliable predictor is available.

    Full Text Available Background & Aim: Electroconvulsive therapy (ECT is a highly effective treatment for affective and schizophrenic disorders. The main objective of this study was to examine the cognitive effects of ECT in patients with major depressive, bipolar and schizophrenia disorders. Methods: In this study we administered a battery of cognitive tasks on 90 patients with major depressive, bipolar and schizophrenia disorders, one day before and after the termination of ECT. The effects were measured by a set of computerized cognitive tests including: auditory reaction time, visual reaction time, verbal memory, Benton visual memory, Wisconsin card sort and motor function. The collected data were analyzed using One-way ANOVA and dependent t-test. Results: The results showed that depressive patients had poorer verbal memory and motor function after the termination of ECT compared to pretest, but their executive function was improved (p<0.05. After the termination of ECT the verbal and visual memory and executive function was significantly improved in patients with bipolar and schizophrenia disorders but their motor function was significantly reduced (p<0.05. Conclusion: Results of this study showed improvement for most cognitive functions in patients after electroconvulsive therapy. Findings of this study may help patients and their families to overcome their fear of electroconvulsive therapy. The results also can aware patients regarding the cognitive effects of electroconvulsive therapy.

    Hypo/anechogenicity of the brainstem raphe (BR) structures has been suggested as a possible transcranial parenchymal sonography (TCS) marker associated with depression. The aim of this study was to analyze possible association of the abnormal BR echogenicity in patients with major depression when compared to healthy controls, and to evaluate its clinical and genetic correlates. TCS was performed in 53 patients diagnosed as major depressive disorder (MDD) without psychotic symptoms and in 54 healthy matched controls. The TCS detected BR abnormalities were significantly more frequent in MDD patients (35 out of 53; 66%) in comparison to matched controls (5 out of 56; 9%). The prevalence of short allele (s) homozygocity in the length polymorphism of the promoter region of the serotonin transporter gene (5-HTTLPR) was significantly higher in MDD patients relative to those with normal BR echogenicity. A stepwise statistical discriminant analysis revealed statistically significant separation between MDD patients with and without BR abnormalities groups based on the four predictors combined: the Hamilton Anxiety Rating Scale item 5 ("difficulty in concentration, poor memory"), presence of social phobia, s allele homozygocity of the 5-HTTLPR polymorphism, and presence of generalized anxiety disorder. Cross-sectional design and heterogenous treatment of depressed patients. Reduced BR echogenicity in at least a subgroup of MDD patients may reflect a particular phenotype, characterized by more prevalent comorbid anxiety disorders, associated with particular genetic polymorphisms and neurotransmitter(s) deficits, most probably altered serotonergic mechanisms.

    Affective disorders may affect patients' time perception. Several studies have described time as a function of the frontal lobe. The activating eff ects of vagus nerve stimulation on the frontal lobe might also modulate time perception in patients with major depressive disorder (MDD). Time perception was investigated in 30 patients with MDD and in 7 patients with therapy-resistant MDD. In these 7 patients, a VNS system was implanted and time perception was assessed before and during stimulation. A time estimation task in which patients were asked "How many seconds have passed?" tested time perception at 4 defined time points (34 s, 77 s, 192 s and 230 s). The differences between the estimated and actual durations were calculated and used for subsequent analysis. Patients with MDD and healthy controls estimated the set time points relatively accurately. A general linear model revealed a significant main eff ect of group but not of age or sex. The passing of time was perceived as significantly slower in patients undergoing VNS compared to patients with MDD at all time points (T34: t = − 4.2; df = 35; p differences in time perception with regard to age, sex or polarity of depression (uni- or bipolar). VNS is capable of changing the perception of time. This discovery furthers the basic research on circadian rhythms in patients with psychiatric disorders.

    Objective: To determine the immune abnormalities and occurrence of infections in transfusion-dependent -thalassemia major patients receiving oral iron chelator deferasirox (DFX). Study Design: An observational study. Place and Duration of Study: Hematology Clinics, King Khalid University Hospital, Riyadh, Saudi Arabia, from July to December 2010. Methodology: Seventeen patients with -thalassemia major (12 females, median age 26 years) receiving deferasirox (DFX) for a median duration of 27 months were observed for any infections and had their immune status determined. Immune parameters studied included serum immunoglobulins and IgG subclasses, serum complement (C3 and C4) and anti-nuclear antibody (ANA) level, total B and T-lymphocytes, CD4+ and CD8+ counts, CD4+/CD8+ ratio, and natural killer (NK) cells. Immunological parameters of the patients were compared with age, gender, serum ferritin level and splenectomy status. Lymphocyte subsets were also compared with age and gender matched normal controls. Results: A considerable reduction in serum ferritin was achieved by DFX from a median level of 2528 to 1875 mol/l. Serum IgG levels were increased in 7 patients. Low C4 levels were found in 9 patients. Total B and T-lymphocytes were increased in 14 patients each, while CD4+, CD8+ and NK cells were increased in 13, 12 and 11 patients respectively. Absolute counts for all lymphocyte subsets were significantly higher compared to the normal controls (p=0.05 for all parameters). Raised levels of IgG were associated with older age, female gender, splenectomized status and higher serum ferritin levels but this did not reach statistical significance except for the higher ferritin levels (p=0.044). Increased tendency to infections was not observed. Conclusion: Patients with -thalassemia major receiving DFX exhibited significant immune abnormalities. Changes observed have been described previously, but could be related to DFX. The immune abnormalities were not associated with

    Full Text Available OBJECTIVES: To study whether emergency department (ED visits by male patients wane simultaneously with the play of scheduled professional and college sports events.METHODS: Retrospective cohort analysis looked at ED male patient registration rates during a time block lasting from two hours before, during, and two hours after the play of professional football games (Monday night, Sundays, post-season play, major league baseball, and a Division I college football and basketball team, respectively. These registration rates were compared to rates at similar times on similar days of the week during the year devoid of a major sporting contest. Games were assumed to have a play time of three hours. Data was collected from April 2000 through March 2003 at an urban academic ED seeing 33,000 male patients above the age of 18 years annually.RESULTS: A total of 782 games were identified and used for purposes of the study. Professional football game dates had a mean of 17.9 males (95% confidence interval [CI] 17.4-18.4 registering vs. 26.8 males (95% CI 25.9-27.6 on non-game days. A registration rate for major league baseball was 18.4 patients (95% CI 17.6-18.4. The mean for registration on comparable non-game days was 23.9 patients (95% CI 22.8-24.3. For the regional Division I college football team, the mean number of patients registering on game days and non-game days was 21.7 (95% CI 20.9-22.4 and 23.4 (95% CI 22.9-23.7, respectively. Division I college basketball play for game and non-game days had mean rates of registration of 14.5 (95% CI 13.9-15.1 and 15.5 (95% CI 15.1-15.9 patients, respectively. For all sports dates collectively, a comparison of two means yielded a mean of 18.2 patients (95% CI 17.4-18.8 registering during the study hours on game days vs. 23.3 patients (95% CI 22.0-23.7 on non-game days. The mean difference was 5.1 patients (95% CI 3.7 to 7.0 with p < .000074.CONCLUSION: Male patient visits to the ED decline during major sporting

    Factor VII deficiency is the most common among the rare autosomal recessive coagulation disorders worldwide. In factor VII deficient patients, the severity and clinical manifestations cannot be reliably determined by factor VII levels. Severe bleeding tends to occur in individuals with factor VII activity levels of 2% or less of normal. Patients with 2-10% factor VII vary between asymptomatic to severe life threatening haemorrhages behaviour. Recombinant factor VIIa (rFVIIa) is the most common replacement therapy for congenital factor VII deficiency. However, unlike haemophilia patients for whom treatment protocols are straight forward, in asymptomatic factor VII deficiency patients it is still debatable. In this study, we demonstrate that a single and very low dose of recombinant factor VIIa enabled asymptomatic patients with factor VII deficiency to go through major surgery safely. This suggestion was also supported by thrombin generation, as well as by thromboelastometry.

    Depression and dementia are commonly concurrent and are both associated with increased mortality among older people. However, little is known about whether home-dwelling patients newly diagnosed with mild dementia coexisting with depressive symptoms have excess mortality. We conducted a post hoc...... analysis based on data from the Danish Alzheimer's Intervention Study of 330 individuals who were diagnosed with mild dementia within the past 12 months. Thirty-four patients were identified with major depressive symptoms (MD-S) at baseline. During the 3-year follow-up period, 56 patients died, and, among...... mortality as compared to the patients without or with only few depressive symptoms. Our result revealed that depression is possibly associated with increased mortality in patients with mild dementia. Given that depression is treatable, screening for depression and treatment of depression can be important...

    We examined serotonin transporter (SERT) binding affinity using single photon emission computed tomography (SPECT) in patients with major depressive disorder (MDD) and night eating syndrome (NES). There are similarities between MDD and NES in affective symptoms, appetite disturbance, nighttime awakenings, and, particularly, response to selective serotonin reuptake inhibitors (SSRIs). Six non-depressed patients with NES and seven patients with MDD underwent SPECT brain imaging with 123I-ADAM, a radiopharmaceutical agent selective for SERT sites. Uptake ratios of 123I-ADAM SERT binding were obtained for the midbrain, basal ganglia, and temporal lobe regions compared to the cerebellum reference region. Patients with NES had significantly greater SERT uptake ratios (effect size range 0.64-0.84) in the midbrain, right temporal lobe, and left temporal lobe regions than those with MDD whom we had previously studied. Pathophysiological differences in SERT uptake between patients with NES and MDD suggest these are distinct clinical syndromes.

    Obesity has been implicated in the pathophysiology of major depressive disorder (MDD), which prompted us to examine the possible association of obesity with cognitive function and brain structure in patients with MDD. Three hundred and seven patients with MDD and 294 healthy participants, matched for age, sex, ethnicity (Japanese), and handedness (right) were recruited for the study. Cognitive function was assessed using the Brief Assessment of Cognition in Schizophrenia (BACS). Gray and white matter structures were analyzed using voxel-based morphometry and diffusion tensor imaging in a subsample of patients (n = 114) whose magnetic resonance imaging (MRI) data were obtained using a 1.5 T MRI system. Verbal memory, working memory, motor speed, attention, executive function, and BACS composite scores were lower for the MDD patients than for the healthy participants (p function, and BACS composite scores were lower in obese patients (body mass index ≥ 30, n = 17) than in non-obese patients (n = 290, p left optic radiation were reduced in obese patients (n = 7) compared with non-obese patients (n = 107, p function, reduced gray matter volume, and impaired white matter integrity in cognition-related brain areas in patients with MDD.

    Depression is believed to be a common side effect in patients receiving beta-blocker therapy. However, diagnoses of depression defined by current diagnostic criteria may not be more common in patients receiving beta-blockers than in patients with the same medical disorder receiving other medications. Seventy-seven patients undergoing elective cardiac catheterization for evaluation of chest pain received a semi-structured diagnostic psychiatric interview. Twenty-one percent of the patients receiving beta-blockers and 33 percent of the patients receiving medications other than beta-blockers met the current American Psychiatric Association criteria for major depressive disorder (DSM-III) (p = NS). The mean heart rate and state anxiety scores for patients taking beta-blockers were significantly lower than those measured in patients taking medications other than beta-blockers. No other medical or demographic differences were observed between the two groups. Despite the methodologic limitations of the study, there does not appear to be a difference in the point prevalence of depression between patients receiving beta-blockers and those receiving other medications.

    In postoperative critically-ill patients who develop Acute Kidney Injury (AKI) it is important to focus on survival and quality of life beyond hospital discharge. The aim of the study was to evaluate outcome and quality of life in patients that develop AKI after major surgery. This retrospective study was carried out in a Post-Anaesthesia Care Unit with five intensive care beds during 2 years. Patients were followed for the development of AKI. Preoperative characteristics, intra-operative management and outcome were evaluated. Six months after discharge, these patients were contacted to complete a Short Form-36 questionnaire (SF-36) and to have their dependency in ADL evaluated. Chi-square or Fischer's exact test were used to compare proportions between groups. A "t test" and a paired "t test" for independent groups was used for comparisons. Of 1584 patients admitted to the PACU, 1200 patients met the inclusion criteria. One hundred-fourteen patients (9.6%) met AKI criteria. Patients with AKI were more severely ill, stayed longer at the PACU. Among 71 hospital survivors at 6 months follow-up, 50 completed the questionnaires. Fifty-two percent of patients reported that their general level of health was better on the day they answered the questionnaire than 12 months earlier. Patients that met AKI criteria after surgery had worse SF-36 scores for physical function, role physical and role emotional domains. Six months after PACU discharge, patients that met AKI criteria were more dependent in I-ADL but not in P-ADL. Patients that develop AKI improved self-perception of quality of life despite having high rate of dependency in ADL tasks. For physical function and role physical domains they had worse scores than PACU patients that did not develop AKI.

    Full Text Available Miranda Caroline Smith,1 Jeremy P Wrobel2 1Respiratory Medicine, Royal Perth Hospital, Perth, WA, Australia; 2Advanced Lung Disease Unit, Royal Perth Hospital, Perth, WA, Australia Abstract: Comorbidities are frequent in chronic obstructive pulmonary disease (COPD and significantly impact on patients' quality of life, exacerbation frequency, and survival. There is increasing evidence that certain diseases occur in greater frequency amongst patients with COPD than in the general population, and that these comorbidities significantly impact on patient outcomes. Although the mechanisms are yet to be defined, many comorbidities likely result from the chronic inflammatory state that is present in COPD. Common problems in the clinical management of COPD include recognizing new comorbidities, determining the impact of comorbidities on patient symptoms, the concurrent treatment of COPD and comorbidities, and accurate prognostication. The majority of comorbidities in COPD should be treated according to usual practice, and specific COPD management is infrequently altered by the presence of comorbidities. Unfortunately, comorbidities are often under-recognized and under-treated. This review focuses on the epidemiology of ten major comorbidities in patients with COPD. Further, we emphasize the clinical impact upon prognosis and management considerations. This review will highlight the importance of comorbidity identification and management in the practice of caring for patients with COPD.

    Full Text Available Foundation: the caregiver plays an important role in helping and supporting a patient with cancer, but at the same time has the emotional and work burden which this work presupposes. Objective: to determine the resilience modulating factors and the degree of burden in major caregivers of advanced cancer patients. Method: a descriptive study was developed at the Area III Policlinic Cienfuegos during the period from December 2012 to March 2013. The universe was constituted by 25 primary caregivers of patients in an advanced stage of the disease. The studied variables were: sex, age, scholarship, occupation, marital status, kinship, time to patient care, self-esteem, optimism, emotional intelligence, and burden. The techniques used were: questionnaire and test of emotional intelligence, Coopersmith self-esteem inventory, caregiver burden scale by Zarit. Results: ages between 51 and 72 years predominated 48 %, 88 % were female, 40 % had elementary school level and 48 % were married, 72 % were housewives, 44 % were patients spouses, 52 % less than a year of care giving. 60 % had an intense burden, 48 % low level of self-esteem and an intense burden. 58.3 % of caregivers with low emotional intelligence had an intense burden. Conclusion: resilience modulators, self-esteem and emotional intelligence determine the level of burden suffered by major caregivers of advanced cancer patients.

    Networked organised systems of care for patients with major trauma now exist in many countries, designed around the needs of the majority of patients (90% adults). Non-accidental injury is a significant cause of paediatric major trauma and has a different injury and age profile from accidental injury (AI). This paper compares the prehospital and inhospital phases of the patient pathway for children with suspected abuse, with those accidentally injured. The paediatric database of the national trauma registry of England and Wales, Trauma Audit and Research Network, was interrogated from April 2012 (the launch of the major trauma networks) to June 2015, comparing the patient pathway for cases of suspected child abuse (SCA) with AI. In the study population of 7825 children, 7344 (94%) were classified as AI and 481 (6%) as SCA. SCA cases were younger (median 0.4 years vs 7 years for AI), had a higher Injury Severity Score (median 16vs9 for AI), and had nearly three times higher mortality (5.7%vs2.2% for AI). Other differences included presentation to hospital evenly throughout the day and year, arrival by non-ambulance means to hospital (74%) and delayed presentation to hospital from the time of injury (median 8 hours vs 1.8 hours for AI). Despite more severe injuries, these infants were less likely to receive key interventions in a timely manner. Only 20% arrived to a designated paediatric-capable major trauma centre. Secondary transfer to specialist care, if needed, took a median of 21.6 hours from injury(vs 13.8 hours for AI). These data show that children with major trauma that is inflicted rather than accidental follow a different pathway through the trauma system. The current model of major trauma care is not a good fit for the way in which child victims of suspected abuse present to healthcare. To achieve better care, awareness of this patient profile needs to increase, and trauma networks should adjust their conventional responses. © Article author

    Full Text Available INTRODUCTION: Personality traits have been associated with primary depression. However, it is not known whether this association takes place in the case of depression comorbid with fibromyalgia. OBJECTIVE: The authors investigated the association between a current major depressive episode and temperament traits (e.g., harm avoidance. METHOD: A sample of 69 adult female patients with fibromyalgia was assessed with the Temperament and Character Inventory. Psychiatric diagnoses were assessed with the Mini-International Neuropsychiatric Interview severity of depressive symptomatology with the Beck Depression Inventory, and anxiety symptomatology with the IDATE-state and pain intensity with a visual analog scale. RESULTS: A current major depressive episode was diagnosed in 28 (40.5% of the patients. They presented higher levels of harm avoidance and lower levels of cooperativeness and self-directedness compared with non-depressed patients, which is consistent with the Temperament and Character Inventory profile of subjects with primary depression. However, in contrast to previous results in primary depression, no association between a major depressive episode and self-transcendence was found. CONCLUSIONS: The results highlight specific features of depression in fibromyalgia subjects and may prove important for enhancing the diagnosis and prognosis of depression in fibromyalgia patients.

    Cardiovascular complications in the postoperative period are associated with high mortality and morbidity. Few studies have assessed the degree of dependence in these patients and their perception of health. The objective of this study was to assess the mortality and the quality of life in patients who developed major cardiac events (MCE) in the postoperative period. Retrospective study carried out in a Surgical Intensive Care Unit (SICU), between March 2006 and March 2008. The patients were assessed regarding the occurrence of CE. Six months after the hospital discharge, the Short-Form-36 (SF-36) questionnaire was filled out and dependence was assessed in relation to activities of daily living (ADL). The comparisons between independent groups of patients were carried out using Student's t test. The comparison between each variable and the occurrence of CE was carried out by logistic regression and included all patients. Of the 1,280 patients that met the inclusion criteria, 26 (2%) developed MCE. The univariate analysis identified as independent determinants for the development of major cardiac events: ASA physical status, hypertension, ischemic heart disease, congestive heart disease and score of the Revised Cardiac Risk Index (RCRI). The six-month mortality after the SICU discharge was 35%. Of the 17 surviving patients, 13 completed the questionnaires. Thirty-one percent of them reported that their general health was better on the day they answered the questionnaire, when compared to 12 months before. Sixty-nine percent of the patients were dependent in instrumental ADL e 15% in personal ADL. The development of MCE has a significant impact on the duration of hospital stay and mortality rates. Six months after the discharge from the SICU, more than 50% of the patients were dependent in at least one instrumental ADL. Copyright 2010 Elsevier Editora Ltda. All rights reserved.

    Severely bleeding trauma patients are a small proportion of the major trauma population but account for 40% of all trauma deaths. Healthcare resource use and costs are likely to be substantial but have not been fully quantified. Knowledge of costs is essential for developing targeted cost reduction strategies, informing health policy, and ensuring the cost-effectiveness of interventions. In collaboration with the Trauma Audit Research Network (TARN) detailed patient-level data on in-hospital resource use, extended care at hospital discharge, and readmissions up to 12 months post-injury were collected on 441 consecutive adult major trauma patients with severe bleeding presenting at 22 hospitals (21 in England and one in Wales). Resource use data were costed using national unit costs and mean costs estimated for the cohort and for clinically relevant subgroups. Using nationally available data on trauma presentations in England, patient-level cost estimates were up-scaled to a national level. The mean (95% confidence interval) total cost of initial hospital inpatient care was £19,770 (£18,177 to £21,364) per patient, of which 62% was attributable to ventilation, intensive care, and ward stays, 16% to surgery, and 12% to blood component transfusion. Nursing home and rehabilitation unit care and re-admissions to hospital increased the cost to £20,591 (£18,924 to £22,257). Costs were significantly higher for more severely injured trauma patients (Injury Severity Score ≥15) and those with blunt injuries. Cost estimates for England were £148,300,000, with over a third of this cost attributable to patients aged 65 years and over. Severely bleeding major trauma patients are a high cost subgroup of all major trauma patients, and the cost burden is projected to rise further as a consequence of an aging population and as evidence continues to emerge on the benefits of early and simultaneous administration of blood products in pre-specified ratios.

    Our previous studies found that disturbances in gut microbiota might have a causative role in the onset of major depressive disorder (MDD). The aim of this study was to investigate whether there were sex differences in gut microbiota in patients with MDD. First-episode drug-naïve MDD patients and healthy controls were included. 16S rRNA gene sequences extracted from the fecal samples of the included subjects were analyzed. Principal-coordinate analysis and partial least squares-discriminant analysis were used to assess whether there were sex-specific gut microbiota. A random forest algorithm was used to identify the differential operational taxonomic units. Linear discriminant-analysis effect size was further used to identify the dominant sex-specific phylotypes responsible for the differences between MDD patients and healthy controls. In total, 57 and 74 differential operational taxonomic units responsible for separating female and male MDD patients from their healthy counterparts were identified. Compared with their healthy counterparts, increased Actinobacteria and decreased Bacteroidetes levels were found in female and male MDD patients, respectively. The most differentially abundant bacterial taxa in female and male MDD patients belonged to phyla Actinobacteria and Bacteroidia, respectively. Meanwhile, female and male MDD patients had different dominant phylotypes. These results demonstrated that there were sex differences in gut microbiota in patients with MDD. The suitability of Actinobacteria and Bacteroidia as the sex-specific biomarkers for diagnosing MDD should be further explored.

    Purpose Major depressive disorder is a frequent emotional mood disorder. To evaluate the changes of brain blood flow in patients with depressive disorder and the correlation between rCBF and clinical feature is very important to diagnosis and treatment of this decease. Methods: Regional cerebral perfusion was investigated using SPECT in 75 patients with depressive disorders. The mean ages of the patients were 41.9 (17-74) Years old. The course of disease was different from several days to over 20 years. Results: 97.3 per cent of patients (73/75) had relative hypoperfusions in some cerebral regions. The patients had a significant decrease of rCBF in the frontal lobesbilaterally, and temporal lobes, basal ganglia, thalamus and parietal lobe. The course of disease and age of the patients had a negative correlation with the changes of rCBF. Conclusion: According to the results of our study, patients with depressive disorders had profound dysfunction of the frontal lobes bilaterally. The temporal cortices and basal ganglia were involved in most patients too. It is coincident with the results of other studies. The function of frontal lobes and temporal lobes is close relation close with affective action, attention, memory, thinking, abstraction, and other brain cognitive function. The clinical symptom of depressive disorder may be relevant with hypoperfusions of frontal lobes and temporal lobes. (authors)

    Health practitioners often regard complaints about the quality of patient care in a negative light. However, complaints can indicate strategies to improve care. Therefore, an audit was undertaken of all formal complaints about patient care at a major Australian hospital over a 30-month period. The profile of complainants, the reasons for complaints, and the outcome were analysed. A total of 1308 complaints, concerning the care of 1267 patients, were received. The complaint rate was 1.12 per 1000 occasions of service. In all, 57% of complaints were lodged by advocates and 71% of complaints related to poor communication or to the treatment provided. In 97% of occasions, an explanation and/or an apology resulted. To date, no complaint has proceeded to litigation. Complaints are potentially useful quality assurance tools and can identify remediable system flaws. Health professionals and employers should understand why patients complain and be able to respond appropriately.

    A large number of studies have demonstrated that depression patients have cognitive dysfunction. With recently developed brain functional imaging, studies have focused on changes in brain function to investigate cognitive changes. However, there is still controversy regarding abnormalities in brain functions or correlation between cognitive impairment and brain function changes. Thus, it is important to design an emotion-related task for research into brain function changes. We selected positive, neutral, and negative pictures from the International Affective Picture System. Patients with major depressive disorder were asked to judge emotion pictures. In addition, functional MRI was performed to synchronously record behavior data and imaging data. Results showed that the total correct rate for recognizing pictures was lower in patients compared with normal controls. Moreover, the consistency for recognizing pictures for depressed patients was worse than normal controls, and they frequently recognized positive pictures as negative pictures. The consistency for recognizing pictures was negatively correlated with the Hamilton Depression Rating Scale. Functional MRI suggested that the activation of some areas in the frontal lobe, temporal lobe, parietal lobe, limbic lobe, and cerebellum was enhanced, but that the activation of some areas in the frontal lobe, parietal lobe and occipital lobe was weakened while the patients were watching positive and neutral pictures compared with normal controls. The activation of some areas in the frontal lobe, temporal lobe, parietal lobe, and limbic lobe was enhanced, but the activation of some areas in the occipital lobe were weakened while the patients were watching the negative pictures compared with normal controls. These findings indicate that patients with major depressive disorder have negative cognitive disorder and extensive brain dysfunction. Thus, reduced activation of the occipital lobe may be an initiating factor for

Hydroxyurea (HU has been shown to enhance HbF levels in patients with sickle cell disease and may be useful in β-thalassemias. We administered HU to 13 patients with β-thalassemia intermedia or major, including 6 splenectomized patients. The patients received escalating doses (10 to 25 mg/kg/d of HU for around 2 years (median: 21 months, range: 8 - 55 months. Eleven patients responded with an increase in the pre-transfusion HbF levels, from a base line median of 8.0% (2.5 - 61.3% to 28.0% (6.6 - 49.2% and 40.7% (4.8 - 72.3% at 3 months and 18 months post-HU, respectively. A concomitant increment in median hemoglobin levels was noted at 1, 3 and 18 months of HU therapy. Six of 7 transfusion-dependent patients who had an increment of HbF (one with β-thalassemia major also had reduced transfusion requirement over the 2-year period of HU therapy. Response to HU was also shown by a reduction in spleen size. Apart from oral ulcers that resolved upon dose reduction of HU, no significant toxicity was noted. We conclude that increased HbF production in β-thalassemia patients, with an improvement in erythropoiesis, can be achieved using HU with minimal toxicity.

    Full Text Available Background. Malnutrition has serious implications for recovery after surgery. Early detection of malnutrition with nutritional support minimizes postoperative complications. Nutritional assessment tools need to be simple and suitable for use in everyday practice. In our study we wanted to determine, how many patients might benefit from nutritional support.Methods. From April to August 1999 fifty consecutively admitted patients predicted to major abdominal surgery have been examined. We used Mini nutritional assessment (MNA, Buzby’s nutrition risk index (NRI, blood albumin level and weight loss in the last 3 months period prior to the examination, to assess nutritional status.Results. We examined 50 patients (27 males and 23 females, age 76.5 ± 16.5 and confirmed malnutrition in 40% of patients with MNA and serum albumin level. The increased risk for nutrition-associated complications was confirmed by NRI and weight loss in 44%.Conclusions. A confident diagnosis of malnutrition and increased risk for nutrition-associated complications can be established by using a combination of simple methods like MNA, NRI, weight loss and serum albumin level. Almost half of the patients admitted for major abdominal surgery in General hospital Celje suffer from malnutrition and they may benefit with early nutritional intervention.

    Depression has become a severe global health problem, and sleeping difficulties are typically associated with depression. The purpose of this study was to investigate the relationships among subjective sleep quality, objective sleep quality, and the sleep hygiene practices of hospitalized patients with major depressive disorder. Daily sleep logs and actigraphy were used to obtain subjective and objective sleep data. Thirty patients were recruited from a regional teaching hospital in Taipei and completed the Hamilton Rating Scale for Depression and the Sleep Hygiene Practice Scale. Significant differences were found between subjective and objective sleep data in patients with major depressive disorder (MDD). For patients with more severe depression, subjective measurements obtained using sleep logs, such as total sleep time and sleep efficiency, were significantly lower than those obtained using actigraphy by controlling for demographics. The results regarding the differences between subjective and objective sleep data can be a reference for care providers when comforting depression patients who complain of sleep disturbance.

    2014-01-01

    Comorbidities are frequent in chronic obstructive pulmonary disease (COPD) and significantly impact on patients’ quality of life, exacerbation frequency, and survival. There is increasing evidence that certain diseases occur in greater frequency amongst patients with COPD than in the general population, and that these comorbidities significantly impact on patient outcomes. Although the mechanisms are yet to be defined, many comorbidities likely result from the chronic inflammatory state that is present in COPD. Common problems in the clinical management of COPD include recognizing new comorbidities, determining the impact of comorbidities on patient symptoms, the concurrent treatment of COPD and comorbidities, and accurate prognostication. The majority of comorbidities in COPD should be treated according to usual practice, and specific COPD management is infrequently altered by the presence of comorbidities. Unfortunately, comorbidities are often under-recognized and under-treated. This review focuses on the epidemiology of ten major comorbidities in patients with COPD. Further, we emphasize the clinical impact upon prognosis and management considerations. This review will highlight the importance of comorbidity identification and management in the practice of caring for patients with COPD. PMID:25210449

    The purpose of the present study was to compare the quality of life of hematological malignancy patients with major depressive disorder or subsyndromal depression. Sample consisted of 93 hematological malignancy patients recruited from oncology ward of Valieasr hospital for Imam Khomeini complex hospital at Tehran through purposeful sampling. Participants were divided into three groups through diagnostic interview based on DSM-IV-TR criteria and the Beck Depression Inventory-2 (BDI-II): Major depressive disorder (MDD) (n = 41; 44.1%); subsyndromal depression (SSD) (n = 23; 24.7%), and without depression (WD) (n = 29; 31.2%). Participants completed the short-form health survey (SF-36) as a measure of the quality of life. We carried out an analysis of covariance to examine the collected data. Findings showed that there was not a significant difference between patients with MDD and SSD based on measure of quality of life. But patients with MDD and SSD showed significantly worse quality of life than patients with WD. This finding highlights the clinical importance of subsyndromal depressive symptoms and casts doubt on the clinical utility of separation between MDD and subsyndromal depression in terms of important clinical outcomes.

    We describe an unusual case of osteosarcoma in a Jehovah's Witness patient who underwent chemotherapy and major surgery without the need for blood transfusion. This 16-year-old girl presented with osteosarcoma of the right proximal tibia requiring proximal tibia resection, followed by endoprosthesis replacement. She was successfully treated with neoadjuvant chemotherapy and surgery with the support of haematinics, granulocyte colony-stimulating factor, recombinant erythropoietin and intraoperative normovolaemic haemodilution. This case illustrates the importance of maintaining effective, open communication and exploring acceptable therapeutic alternative in the management of these patients, whilst still respecting their beliefs.

    Full Text Available Morbidly obese patients with clinical features of obstructive sleep apnoea can present a myriad of challenges to the anaesthesiologists which must be addressed to minimise the perioperative risks. Initiation of continuous positive airway pressure (CPAP therapy early in the pre- and post-operative period along with appropriate anaesthetic planning is of paramount importance in such patients. This case report emphasises the usefulness of CPAP therapy, even for a short duration, to minimise morbidity, improve recovery and hasten early discharge from the hospital after major surgery.

    Quantitative abnormalities of brain structure in patients with major depressive disorder have been reported at a group level for decades. However, these structural differences appear subtle in comparison with conventional radiologically defined abnormalities, with considerable inter-subject variability. Consequently, it has not been possible to readily identify scans from patients with major depressive disorder at an individual level. Recently, machine learning techniques such as relevance vector machines and support vector machines have been applied to predictive classification of individual scans with variable success. Here we describe a novel hybrid method, which combines machine learning with feature selection and characterization, with the latter aimed at maximizing the accuracy of machine learning prediction. The method was tested using a multi-centre dataset of T(1)-weighted 'structural' scans. A total of 62 patients with major depressive disorder and matched controls were recruited from referred secondary care clinical populations in Aberdeen and Edinburgh, UK. The generalization ability and predictive accuracy of the classifiers was tested using data left out of the training process. High prediction accuracy was achieved (~90%). While feature selection was important for maximizing high predictive accuracy with machine learning, feature characterization contributed only a modest improvement to relevance vector machine-based prediction (~5%). Notably, while the only information provided for training the classifiers was T(1)-weighted scans plus a categorical label (major depressive disorder versus controls), both relevance vector machine and support vector machine 'weighting factors' (used for making predictions) correlated strongly with subjective ratings of illness severity. These results indicate that machine learning techniques have the potential to inform clinical practice and research, as they can make accurate predictions about brain scan data from

  3. Nitric Oxide-Related Biological Pathways in Patients with Major Depression.

    Full Text Available Major depression is a well-known risk factor for cardiovascular diseases and increased mortality following myocardial infarction. However, biomarkers of depression and increased cardiovascular risk are still missing. The aim of this prospective study was to evaluate, whether nitric-oxide (NO related factors for endothelial dysfunction, such as global arginine bioavailability, arginase activity, L-arginine/ADMA ratio and the arginine metabolites asymmetric dimethylarginine (ADMA and symmetric dimethylarginine (SDMA might be biomarkers for depression-induced cardiovascular risk.In 71 in-patients with major depression and 48 healthy controls the Global Arginine Bioavailability Ratio (GABR, arginase activity (arginine/ornithine ratio, the L-arginine/ADMA ratio, ADMA, and SDMA were determined by high-pressure liquid chromatography. Psychiatric and laboratory assessments were obtained at baseline at the time of in-patient admittance and at the time of hospital discharge.The ADMA concentrations in patients with major depression were significantly elevated and the SDMA concentrations were significantly decreased in comparison with the healthy controls. Even after a first improvement of depression, ADMA and SDMA levels remained nearly unchanged. In addition, after a first improvement of depression at the time of hospital discharge, a significant decrease in arginase activity, an increased L-arginine/ADMA ratio and a trend for increased global arginine bioavailability were observed.Our study results are evidence that in patients with major depression ADMA and SDMA might be biomarkers to indicate an increased cardiovascular threat due to depression-triggered NO reduction. GABR, the L-arginine/ADMA ratio and arginase activity might be indicators of therapy success and increased NO production after remission.

    Major depressive disorder (MDD) is one the most common mental disorders; it affects about 5-10% of the world population. This study explores the experiences of people with major depressive disorder in Zanjan, Iran. In order to identify recurring themes and patterns in individuals' experiences of major depressive disorder, semi-structured interviews with 18 patients were recorded and transcribed verbatim. The transcripts were then analyzed based on conventional qualitative content analysis. Five main categories emerged. The first category was called emotional paralysis and included the subcategories feeling severely depressed; feeling anxious; feeling impatient and irritable; and having dyshedonia. The second category was disturbance of thinking and was comprised of the subcategories of preoccupation, instable spiritual beliefs, and guilt. Cognitive decline was the third identified category and was further divided into subcategories of frustration, unawareness of the disorder, negative evaluation, indecisiveness, and loss of focus and loss of memory. Another major category was physical illnesses with the subcategories of physical discomfort, sleep problems, appetite disturbance, facial changes, sexual dysfunction, and medical conditions. The final category was failure in life, which had failure in personal affairs, jeopardized interpersonal relations, and unstable work life as subcategories. These findings provide a base for further research in this area. They also have clinical relevance for health care providers working with patients with MDD. Related cultural issues also are discussed.

    We measured the cross-sectional area (CSA) of the psoas major muscles of 48 male patients under 50 years of age with unilateral sciatica caused by a single-level lumbar disc herniation. Patients who had multi-level disc lesions, lumbar canal stenosis, spondylolisthesis, scoliosis>5deg, or a history of lumbar surgery or hip joint disease were excluded. Mean age at surgery was 33 years old. Two orthopedic surgeons measured the CSA independently and blindly on magnetic resonance images in which the spinal canal had been blacked out. The CSA ratio (pain-positive side/pain-negative side) was 0.99 at L3/4, 0.98 at L4/5, and 1.00 at L5/S. There was a statistically significant difference between the CSA of the psoas major muscle on the painful side and the unaffected side at L4/5 (p=0.02). There was no correlation between the CSA ratio and the angle in the straight leg raising test, the duration of symptoms, or the size of the disc herniation. The atrophy of the psoas major muscle observed on the pain-positive side in lumbar disc herniation patients may be attributable to disuse of the affected leg. (author)

    To describe plain radiographic and thin-section CT findings of hematogenous candida pneumonia in major burn patients. We reviewed nine cases of hematogenous candida pneumonia in major burn patients who had positive blood culture for candida and findings of pneumonia on plain chest radiograph. On five of nine cases, thin-section CT was done. We evaluated retrospectively nine cases for onset, the pattern, distribution, and size of lesions on plain chest radiograph and thin-section CT. On plain chest radiograph, randomly distributed 2-10 mm nodules were seen in six cases(66%) and randomly distributed 10-15 mm consolidations in remaining three cases(33%). Lesion occurred in 11th to 75th post-burn day(average, 34th post-burn day). Other findings were cardiomegaly in three cases, atelectasis in three cases, and pulmonary edema in one case. Thin-section CT showed variable shaped subpleural nodules in all five cases. The size of nodules were 1-5 mm in two cases(40%) and 5-10 mm(60%) in three cases. Feeding vessel signs were seen in two cases. Other findings were atelectasis in three cases, cardiomegaly in three cases, ground-glass opacity and interlobular septal thickenings by pulmonary edema in two cases. Plain chest radiographic findings of hematogenous candida pneumonia in major burn patients are randomly distributed nodules or consolidations of variable size. Thin-section CT findings are variable shaped subpleural nodules less than 1 cm

    Overgeneral autobiographical memory has been identified as a risk factor for the onset and maintenance of depression. However, little is known about the underlying mechanisms that might explain overgeneral autobiographical memory phenomenon in depression. The purpose of this study was to test the mediation effects of rumination on the relationship between overgeneral autobiographical memory and depressive symptoms. Specifically, the mediation effects of brooding and reflection subtypes of rumination were examined in patients with major depressive disorder. Eighty-seven patients with major depressive disorder completed the 17-item Hamilton Depression Rating Scale, Ruminative Response Scale, and Autobiographical Memory Test. Bootstrap mediation analysis for simple and multiple mediation models through the PROCESS macro was applied. Simple mediation analysis showed that rumination significantly mediated the relationship between overgeneral autobiographical memory and depression symptoms. Multiple mediation analyses showed that brooding, but not reflection, significantly mediated the relationship between overgeneral autobiographical memory and depression symptoms. Our results indicate that global rumination partly mediates the relationship between overgeneral autobiographical memory and depressive symptoms in patients with major depressive disorder. Furthermore, the present results suggest that the mediating role of rumination in the relationship between overgeneral autobiographical memory and depression is mainly due to the maladaptive brooding subtype of rumination.

    Vitamin D deficiency has been associated with an increased risk of depression and schizophrenia. The aim was to compare serum levels of vitamin D, calcium, phosphorus and parathyroid hormone in schizophrenics, depressed patients and healthy subjects in an Iranian population. In a cross-sectional study, 100 patients with schizophrenia and 100 with major depression were enrolled. A questionnaire was filled by using medical records of patients. After that a serum sample was taken and levels of vitamin D, calcium, phosphorus and parathyroid hormone were assessed and then compared between the three groups. Post-hoc analysis of Tukey showed that vitamin D level in healthy participants was significantly higher than depressed patients and schizophrenics while there was no significant difference between vitamin D level in depressed and schizophrenic patients. The findings suggest that vitamin D affects the brain independent of hormonal pathways which regulate serum level of calcium. Non-significant difference in the serum level of vitamin D between the schizophrenics and the depressed patients suggests that the independent effect of vitamin D in brain is a general effect and is not specialized to a specific region or pathway in the brain; however, differences between psychiatric and non-psychiatric patients might be resulted from differences in psychosocial backgrounds.

    The aim of the current study was to determine whether the serum prolidase levels are associated with the etiopathogenesis of depression. This study included 29 patients with major depressive disorder (MDD), who were consecutively recruited from the psychiatric outpatient clinic, and 30 healthy individuals recruited from the general community. Each patient underwent a detailed diagnostic evaluation by two psychiatrists using the Structured Clinical Interview for DSM-IV (SCID-I). Serum prolidase activity and oxidative parameters were measured in the patient and control groups. The severity of depressive symptoms was assessed using the Hamilton Depression Rating Scale. Serum prolidase level was significantly higher in patients with MDD compared to healthy subjects (pStress Index (OSI) were also significantly higher in patients with MDD (pstress in patients with MDD. Increased serum prolidase levels in patients with MDD may be interpreted as the interaction of prolidase activity, glutamate transmission and oxidative stress. It is suggested that prolidase activity is involved in the etiopathogenesis of depressive disorder.

    Background East Asian countries have high suicide rates. However, little is known about clinical and sociodemographic factors associated with suicidality in Asian populations. The aim of this study was to evaluate the factors associated with suicidality in patients with major depressive disorder (MDD) from six Asian countries. Methods The study cohort consisted of 547 outpatients with MDD. Patients presented to study sites in China (n = 114), South Korea (n = 101), Malaysia (n = 90), Singapore (n = 40), Thailand (n = 103), and Taiwan (n = 99). All patients completed the Mini-International Neuropsychiatric Interview (MINI), the Montgomery–Asberg Depression Rating Scale (MADRS), the Global Severity Index(SCL-90R), the Fatigue Severity Scale, the 36-item short-form health survey, the Sheehan Disability Scale, and the Multidimensional Scale of Perceived Social Support (MSPSS). Patients were classified as showing high suicidality if they scored ≥6 on the MINI suicidality module. Multivariate logistic regression analysis was used to examine sociodemographic and clinical factors related to high suicidality. Results One hundred and twenty-five patients were classed as high suicidality. Unemployed status (adjusted odds ratio [OR] 2.43, p suicidality. Hindu (adjusted OR 0.09, p suicidality. Conclusions A variety of sociodemographic and clinical factors were associated with high suicidality in Asian patients with MDD. These factors may facilitate the identification of MDD patients at risk of suicide. PMID:24524225

    To identify regional vasodilatory capacity and its sequential change, we evaluated prospectively a total of 78 acetazolamide tests in 51 patients with occlusion or greater than 75% stenosis of the carotid or middle cerebral arteries. The relative distribution of cerebral blood flow was determined by single photon emission computed tomography using N-isopropyl-p-({sup 123}I)-iodoamphetamine before and after intravenous injection of acetazolamide. Reduced vasodilatory capacity was demonstrated in 20 patients (38%), including 5 patients with hemodynamic transient ischemic attacks or infarction. Follow-up acetazolamide tests revealed asymptomatic progression of the arterial lesion (from stenosis to occlusion) in 1 patient and almost complete improvement of vasodilatory capacity in 5 patients, including 3 without surgical intervention. During an average follow-up period of 18.5 months, 4 patients died from cardiac causes or neoplasm; no neurovascular events occurred. Much larger numbers of patients with longer observation periods will be necessary to clarify the contribution of chronic hemodynamic failure to subsequent stroke. However, the present data indicate that the acetazolamide test is useful for assessing the course of high grade stenosis or occlusion of major cerebral arteries. (orig.).

    The purpose of this study was to report the prevalence of thrombus within a retrievable vena cava filter inserted prophylactically in major trauma patients referred for filter extraction. Between November 2002 and August 2005, 80 retrievable inferior vena cava filters (68 Optease and 12 Gunther-Tulip) were inserted into critically injured trauma patients (mean injury severity score 33.5). The filters were inserted within 1 to 6 (mean 2) days of injury. Thirty-seven patients were referred for filter removal (32 with Optease and 5 with Gunther-Tulip). The indwelling time was 7 to 22 (mean 13) days. All patients underwent inferior vena cavography prior to filter removal. There were no insertion-related complications and all filters were successfully deployed. Forty-three (54%) of the 80 patients were not referred for filter removal, as these patients continued to have contraindications to anticoagulation. Thirty-seven patients (46%) were referred for filter removal. In eight of them (22%) a large thrombus was seen within the filters and they were left in place, all with the Optease device. The other 29 filters (36%) were removed uneventfully.We conclude that the relatively high prevalence of intrafilter thrombi with the Optease filter may be explained by either spontaneous thrombus formation or captured emboli.

    Full Text Available Introduction: This study was conducted to assess the nutritional status in Iranian major depres-sive disorder patients. We also determined the relationship between nutrients intake with depres-sion severity.Methods: Seventy major depressive patients were selected randomly from outpatient depressive subjects, referred to Razi Psychiatry Hospital in Tabriz, Iran in 2007. Dietary intakes were rec-orded and compared with dietary reference intakes (DRIs. Definition of the disease and its se-verity were according to DSM-IV-TR and Hamilton Depression Rating Scale, respectively. Nu-tritionist III program, Chi-square, correlation and t-test were used for data analyses. Demo-graphic, clinical and laboratory data were analyzed using SPSS software for windows (ver-sion13.0.Results: According to dietary analysis, 11.4% and 55% of patients had dietary protein and energy deficiency, respectively. 97.1% and 95.7% of patients had less folate and B12 intakes than recom-mended dietary allowances. The mean (Mean ± SD for plasma folate and B12 was 5.18±6.11 ng/ml and 389.05±346.9 pg/ml, respectively. Low plasma folate and B12 was observed in 51.4% and 50.0 % of patients, respectively. There was no significant relationship between blood folate and B12 levels with depression severity. Similarly, nutrients intake had no effect on depression se-verity.Conclusions: Low plasma concentrations and low dietary intakes of folate and B12 are common among Tabrizian depressive patients. It seems that nutritional intervention for increasing folate and vitamin B12 intake must be considered as health promotive and preventative program for pa-tients suffering from depression disorders.

Adjusting for age, gender, ISS, GCS, injury mechanism and comorbid status, Hong Kong patients demonstrated comparable mean PCS-12 scores at 6-months (adjusted mean difference: 1.2, 95% CI: −1.2, 3.6) and 12-months (adjusted mean difference: −0.4, 95% CI: −3.2, 2.4) compared to Victorian patients. Keeping age, gender, ISS, GCS, injury mechanism and comorbid status, there was no difference in the MCS-12 scores of Hong Kong patients compared to Victorian patients at 6-months (adjusted mean difference: 0.4, 95% CI: −2.1, 2.8) or 12-months (adjusted mean difference: 1.8, 95% CI: −0.8, 4.5). Conclusion The unadjusted analyses showed better outcomes for Victorian cases compared to Hong Kong but after adjusting for key confounders, there was no difference in 6-month or 12-month functional outcomes between the jurisdictions.

    Objective: In this post hoc analysis, improvement in functional impairment in patients with major depressive disorder (MDD) treated with levomilnacipran extended release (ER) was evaluated by assessing shifts from more severe to less severe functional impairment categories on individual Sheehan Disability Scale (SDS) subscales. Method: SDS data were pooled from 5 phase II/III studies conducted between December 2006 and March 2012 of levomilnacipran ER versus placebo in adult patients with MDD (DSM-IV-TR criteria). Proportions of patients shifting from moderate-extreme baseline impairment (score ≥ 4) to mild-no impairment (score ≤ 3) at end of treatment were assessed for each SDS subscale. Proportions of patients shifting from marked-extreme (score ≥ 7) baseline impairment to moderate-no (score ≤ 6) or mild-no impairment (score ≤ 3) at end of treatment, and shifts in which patients worsened from moderate-no to marked-extreme impairment, were also evaluated. Results: A significantly higher proportion of patients treated with levomilnacipran ER than placebo-treated patients improved from more severe categories of functional impairment at baseline to less severe impairment categories across all SDS subscales: work/school, social life, and family life/home responsibilities (P impairment at baseline improved to mild or no impairment, compared with no more than 40% of placebo patients on any subscale. Almost half (42%–47%) of levomilnacipran ER–treated patients versus only about one-third (29%–34%) of placebo patients improved from marked-extreme to mild or no impairment across functional domains. Conclusions: These results suggest that functional improvement was observed across the SDS functional domains. To our knowledge, this is the first such categorical analysis of functional improvement, as measured by the SDS, for an antidepressant.

    To investigate the outcome of subjects with major depressive disorder after serious suicide attempt and to examine the effect of psychotic symptoms on their outcome. The study population included all individuals aged 16 years or older in Finland who were hospitalized with ICD-10 diagnoses of major depressive disorder and attempted suicide from 1996 to 2003 (N = 1,820). The main outcome measures were completed suicides, overall mortality, and repeated suicide attempts during drug treatment versus no treatment. During the 4-year follow-up period, 13% of patients died, 6% completed suicide, and 31% made a repeat suicide attempt. Subjects with major depression with psychotic features completed suicide more often than subjects without psychotic features during the follow-up (hazard ratio [HR] 3.32; 95% CI, 1.95 - 5.67). Antidepressant treatment reduced all-cause mortality by 24% (HR 0.74; 95% CI, 0.56 - 0.97) but did not reduce suicide mortality (HR 1.06; 95% CI, 0.71 - 1.58). Psychotic symptoms during major depressive episode increase the risk of completed suicide after serious suicide attempt. The quality of treatment for major depression with psychotic features after attempted suicide should be improved to prevent suicide. Copyright 2009 Physicians Postgraduate Press, Inc.

    Previous research has focussed extensively on the distinction of HPA-axis functioning between patient groups and healthy volunteers, with relatively little emphasis on a direct comparison of patient groups. The current study's aim was to analyse differences in the cortisol stress response as a function of primary diagnosis of panic disorder (PD), post-traumatic stress disorder (PTSD), and major depressive disorder (MDD). A total of n=30 PD (mean age±SD: 36.07±12.56), n=23 PTSD (41.22±10.17), n=18 MDD patients (39.00±14.93) and n=47 healthy control (HC) individuals (35.51±13.15) participated in this study. All the study participants were female. The Trier Social Stress Test (TSST) was used for reliable laboratory stress induction. Blood sampling accompanied the TSST for cortisol and ACTH assessment. Panic-related, PTSD-specific questionnaires and the Beck Depression Inventory II were handed out for the characterisation of the study groups. Repeated measure ANCOVAs were conducted to test for main effects of time or group and for interaction effects. Regression analyses were conducted to take comorbid depression into account. 26.7% of the PD patients, 43.5% of the PTSD patients, 72.2% of the MDD patients and 80.6% of the HC participants showed a cortisol stress response upon the TSST. ANCOVA revealed a cortisol hypo-responsiveness both in PD and PTSD patients, while no significant group differences were seen in the ACTH concentrations. Additional analyses showed no impact of comorbid depressiveness on the cortisol stress response. MDD patients did not differ in the hormonal stress response neither compared to the HC participants nor to the PD and PTSD patients. Our main findings provide evidence of a dissociation between the cortisol and ACTH concentrations in response to the TSST in PTSD and in PD patients, independent of comorbid depression. Our results further support overall research findings of a cortisol hypo-responsiveness in PD patients. A hypo

The population under study was comprised of people from six primary care facilities, who had a MD episode between January 2003 and March 2007. A specialist in psychiatry assessed a random sample of patient histories and determined whether a certain patient was in remission according to clinical criteria (ICPC-2). Regarding the databases, patients were considered in remission when they did not need further prescriptions of AD for at least 6 months after completing treatment for a new episode. Validity indicators (sensitivity [S], specificity [Sp]) and clinical utility (positive and negative probability ratio [PPR] and [NPR]) were calculated. The concordance index was established using Cohen's kappa coefficient. Significance level was p Reliability analysis: Cronbach's alpha: 90.6% (CI was 95%: 85.6 - 95.6%). Results show an acceptable level of concordance between remission obtained from the computerized databases and clinical criteria. The major discrepancies were found in diagnostic accuracy.

    There is an increased evidence of an association between inflammatory mediators, particularly serum IL-6, depression and cognitive impairment in the elderly. This study aims at exploring the relation of peripheral IL-6 to cognitive functions in elderly patients with major depressive disorder (MDD). (1) Assessment of serum IL-6 levels and cognitive functions in elderly patients suffering from major depression and comparing them to healthy age-matched control subjects; (2) correlation between serum IL-6 levels and clinical characteristics of depression and cognitive functions in these patients. The study is an observational, case-control study. It consisted of 80 subjects, 40 with the diagnosis of MDD according to the Diagnostic and Statistical Manual of Mental Disorders (DSM IV-TR) with early onset (first episode before the age of 60) and 40 community-dwelling subjects. They were subjected to the Structured Clinical Interview according to DSM-IV, Montreal Cognitive Assessment, Montgomery Asberg Depression Rating Scale, and serum IL-6 assay using ELISA. In the depression group, subjects had lower scores in cognitive testing, than the control group (p = 0.001). Serum IL-6 was found to have a negative correlation with cognitive testing in these patients even after controlling for the severity of depressive status and Body Mass Index (BMI) (p = 0.025). MDD in elderly subjects is associated with decline in cognitive functions that may be related to peripheral IL-6 levels.

    Thalassaemia represent one of the most common single gene disorder causing a major public health problem in Pakistan. Nearly 100,000 people are born worldwide with this severe blood disorder every year. Over the last 3 decades, the development of regular transfusion therapy and iron chelation has dramatically improved the quality of life and transformed thalassaemia from a rapidly fatal disease to a chronic disease compatible with prolonged survival. Objective of this observational cross sectional study was to determine the effects of chronic anaemia and transfusional iron overload on the left ventricular function using Doppler echocardiography. This study was conducted in the Department of Paediatric Cardiology, The Children's Hospital and Institute of Child Health, Lahore, Pakistan from first April 2006 to September 30, 2007. The study comprised of 50 consecutive cases of beta-Thalassaemia major and 30 controls with normal haemoglobin and electrophoresis pattern. beta- Thalassaemia major patients were diagnosed on the basis of haemoglobin electrophoresis. Patients with any congenital or acquired heart disease, concurrent infective disorder and with history of cardiac surgery were excluded from the study. 2-D, M-mode and Doppler echocardiography was performed in all the study cases and controls. Statistical comparison of study cases and controls was conducted by using unpaired t-test. The age of the patients ranged from 2 years to 25 years with mean age of 9.65 years. Males were 34 (68%) and females were 16 (32%). None of the study cases was on regular chelation programme while 31 (62%) patients were on irregular chelation with single dose of intravenous desferrioxamine only at the time of blood transfusion. 19 (38%) of the patients had LV dysfunction in the form of isolated systolic dysfunction in 2 (4%), isolated diastolic dysfunction in 15 (30%) while global dysfunction in 2 (4%) of the patients. Left ventricular dimensions, stroke volume and E/A ratio were

    Full Text Available BACKGROUND Haemochromatosis is a genetic form of iron overload due to a defective HFE gene. Secondary iron overload is the main complication in transfusion-dependent thalassaemia major patients. This study aims at evaluating the degree of iron overload in β-thalassaemia major patients with and without HFE mutations (C282Y, H63D and S65C. MATERIALS AND METHODS A descriptive observational study was conducted including fifty diagnosed -thalassaemia major cases. Detailed clinical history and iron profile was estimated. DNA analysis by PCR-RFLP method for HFE gene mutations was performed. RESULTS After DNA analysis of all the thalassaemia major cases, two groups were identified, one with HFE gene mutation and other without HFE gene mutation. Iron profile of both the groups (with and without HFE gene mutation was estimated and compared. Only H63D mutation (out of three HFE gene mutations was detected in 16% cases (8 out of 50 cases, which comprised the group with mutation. Comparison of iron parameters between two groups (with and without HFE gene mutation showed significant difference in percent transferrin saturation (p=0.02, while other iron parameters (serum iron and serum ferritin did not show significant difference. CONCLUSION No significant difference between serum ferritin values (a marker of iron overload of groups with and without mutation (mean ferritin level 4641±2166 ng/mL and 4170±2461 ng/mL, respectively was found (p=0.61, in a patient population in whom transfusion protocol and proper chelation regimen was followed.

    Background Exercise test (ET) is the preferred initial noninvasive test for the diagnosis and risk stratification of coronary artery disease (CAD), however, its lower sensitivity may fail to identify patients at greater risk of adverse events. Objective To assess the value of stress echocardiography (SE) for predicting all-cause mortality and major cardiac events (MACE) in patients with intermediate pretest probability of CAD and a normal ET. Methods 397 patients with intermediate CAD pretest probability, estimated by the Morise score, and normal ET who underwent SE were studied. The patients were divided into two groups according to the absence (G1) or presence (G2) of myocardial ischemia on SE .End points evaluated were all-cause mortality and MACE, defined as cardiac death and nonfatal acute myocardial infarction (AMI). Results G1 group was comprised of 329 (82.8%) patients. The mean age of the patients was 57.37 ± 11 years and 44.1% were male. During a mean follow-up of 75.94 ± 17.24 months, 13 patients died, three of them due to cardiac causes, and 13 patients suffered nonfatal AMI. Myocardial ischemia remained an independent predictor of MACE (HR 2.49; [CI] 95% 1.74-3.58). The independent predictors for all-cause mortality were male gender (HR 9.83; [CI] 95% 2.15-44.97) and age over 60 years (HR 4.57; [CI] 95% 1.39-15.23). Conclusion Positive SE for myocardial ischemia is a predictor of MACE in the studied sample, which helps to identify a subgroup of patients at higher risk of events despite having normal ET.

    Olfactory deficits, in detection, recognition and identification of odorants have been documented in ageing and in several neurodegenerative and psychiatric conditions. However, olfactory abilities in Major Depressive Disorder (MDD) have been less investigated, and available studies have provided inconsistent results. The present study assessed odour recognition memory and odour identification in two groups of 12 mild MDD patients (M age 41.3, range 25-57) and 12 severe MDD patients (M age, 41.9, range 23-58) diagnosed according to DSM-IV criteria and matched for age and gender to 12 healthy normal controls. The suitability of olfactory identification and recognition memory tasks as predictors of the progression of MDD was also addressed. Data analyses revealed that Severe MDD patients performed significantly worse than Mild MDD patients and Normal controls on both tasks, with these last groups not differing significantly from one another. The present outcomes are consistent with previous studies in other domains which have shown reliable, although not conclusive, impairments in cognitive function, including memory, in patients with MDD, and highlight the role of olfactory identification and recognition tasks as an important additional tool to discriminate between patients characterised by different levels of severity of MDD.

    Previous studies have identified the significant role of stressful life events in the onset of depressive episodes. However, there is a paucity of cross-national studies on stressful life events that precede depression. We aimed to compare types of stressful life events associated with the onset of depressive episodes in patients with major depressive disorder (MDD) in five Asian countries. A total of 507 outpatients with MDD were recruited in China (n = 114), South Korea (n = 101), Malaysia (n = 90), Thailand (n = 103) and Taiwan (n = 99). All patients were assessed with the Mini-International Neuropsychiatric Interview and the List of Threatening Experiences. The prevalence of each type of stressful life events was calculated and compared between each country. The type of stressful life event that preceded the onset of a depressive episode differed between patients in China and Taiwan and those in South Korea, Malaysia and Thailand. Patients in China and Taiwan were less likely to report interpersonal relationship problems and occupational/financial problems than patients in South Korea, Malaysia and Thailand. Understanding the nature and basis of culturally determined susceptibilities to specific stressful life events is critical for establishing a policy of depression prevention and providing effective counseling services for depressed patients. © The Author(s) 2015.

    Suicide is a common reason for psychiatric emergency and morbidity, with few effective treatments. Anxiety symptoms have emerged as potential modifiable risk factors in the time before a suicide attempt, but few studies have been conducted using laboratory measures of fear and anxiety. We operationally defined fear and anxiety as increased startle reactivity during anticipation of predictable (fear-potentiated startle) and unpredictable (anxiety-potentiated startle) shock. We hypothesized that a lifetime history of suicide attempt (as compared to history of no suicide attempt) would be associated with increased fear-potentiated startle. A post-hoc analysis of fear- and anxiety-potentiated startle was conducted in 28 medication-free patients with Major Depressive Disorder (MDD) divided according to suicide attempt history. The magnitude of fear-potentiated startle was increased in depressed patients with lifetime suicide attempts compared to those without a lifetime history of suicide attempt (F(1,26)=5.629, p=.025). There was no difference in anxiety-potentiated startle by suicide attempt history. This is a post-hoc analysis of previously analyzed patient data from a study of depressed inpatients. Further replication of the finding with a larger patient sample is indicated. Increased fear-potentiated startle in suicide attempters suggests the role of amygdala in depressed patients with a suicide attempt history. Findings highlight the importance of anxiety symptoms in the treatment of patients at increased suicide risk. Published by Elsevier B.V.

    Postoperative hematomas are one of the most frequent complications following aesthetic surgery. Identifying risk factors for hematoma has been limited by underpowered studies from single institution experiences. To examine the incidence and identify independent risk factors for postoperative hematomas following cosmetic surgery utilizing a prospective, multicenter database. A prospectively enrolled cohort of patients who underwent aesthetic surgery between 2008 and 2013 was identified from the CosmetAssure database. Primary outcome was occurrence of major hematomas requiring emergency room visit, hospital admission, or reoperation within 30 days of the index operation. Univariate and multivariate analysis was used to identify potential risk factors for hematomas including age, gender, body mass index (BMI), smoking, diabetes, type of surgical facility, procedure by body region, and combined procedures. Of 129,007 patients, 1180 (0.91%) had a major hematoma. Mean age (42.0 ± 13.0 years vs 40.9 ± 13.9 years, P hematomas. Males suffered more hematomas than females (1.4% vs 0.9%, P Hematoma rates were higher in patients undergoing combined procedures compared to single procedures (1.1% vs 0.8%, P hematoma included age (Relative Risk [RR] 1.01), male gender (RR 1.98), the procedure being performed in a hospital setting rather than an office-based setting (RR 1.68), combined procedures (RR 1.35), and breast procedures rather than the body/extremity and face procedures (RR 1.81). Major hematoma is the most common complication following aesthetic surgery. Male patients and those undergoing breast or combined procedures have a significantly higher risk of developing hematomas. 2. © 2017 The American Society for Aesthetic Plastic Surgery, Inc.

However, whether sleep-dependent procedural memory consolidation occurs in patients medicated for major depressive disorder remains unclear, as are the pharmacological and physiological mechanisms that underlie this process.Methods: Healthy control participants (n=17 and patients medicated for major depressive disorder (n=11 were recruited and subjected to a finger-tapping motor sequence test (MST; nondominant hand paradigm to compare the averaged scores of different learning phases (presleep, postsleep, and overnight improvement. Participants' brain activity was recorded during sleep with 16 electroencephalography channels (between MSTs. Sleep scoring and frequency analyses were performed on the electroencephalography data. Additionally, we evaluated sleep spindle activity, which divided the spindles into fast-frequency spindle activity (12.5–16 Hz and slow-frequency spindle activity (10.5–12.5 Hz.Result: Sleep-dependent motor memory consolidation in patients with depression was impaired in comparison with that in control participants. In patients with depression, age correlated negatively with overnight improvement. The duration of slow-wave sleep correlated with the magnitude of motor memory consolidation in patients with depression, but not in healthy controls. Slow-frequency spindle activity was associated with reduction in the magnitude of motor memory consolidation in both groups.Conclusion: Because the changes in slow

    Full Text Available Electroconvulsive therapy (ECT is considered an effective treatment for major depression with melancholic features. However, neurocognitive side-effects such as anterograde amnesia still regularly occur. The present study aims to evaluate the severity and course of anterograde amnesia in severely depressed patients undergoing ECT. In a prospective naturalistic study, anterograde memory function was assessed among inpatients who underwent ECT (n = 11. Subjects met DSM-IV criteria for major depressive disorder. Recruitment took place between March 2010-March 2011 and March 2012-March 2013. Controls treated with antidepressants (n = 9 were matched for age, gender and depression severity. Primary outcome measure was immediate recall; secondary outcome measures were delayed recall, recognition, and visual association. Differences were tested using repeated measures ANOVA and paired t-tests. Correlations with hypothesized covariates were calculated. In patients with major depressive disorder, ECT had a significant effect on delayed memory function (p<0.01 with large effect sizes. Findings on immediate recall were less consistent. Four weeks after treatment discontinuation, these memory functions had recovered. Age was identified as a very important covariate. The main limitations of our study are its naturalistic design, possibly compromising internal validity, and its small sample size. However, if these findings can be reproduced in a more comprehensive study group, then the possible induction of anterograde amnesia is not a justifiable reason for clinicians to disregard ECT as a treatment option.

    The co-morbidity of major depressive disorder (MDD ) with personality disorders (PDs) in patients with long-standing work disability at a psychiatry clinic was investigated. The purpose of our study was to evaluate personality for contributing to disability in patients with MDD and to investigate the relationship with these two psychometric characters in patients with MDD. Seventy-two patients with a MDD and 72 healthy controls were assessed by means of both clinician and self-rating scales for depression, anxiety, disability, and the SCID-II personality inventory. There was no difference between the personality parameters of the groups regarding schizotypal and antisocial PDs. Avoidant personality was found to be less common in the patient group (p=0.030). Dependent (p less than 0.001), obsessive (p=0.003), passive-aggressive (p=0.025), self-defeating (p less than 0.001), paranoid (p less than 0.001), schizoid (p=0.012), histrionic (p=0.001), narcissistic (p less than 0.001), and borderline (p less than 0.001) PDs in patients were more common than in controls. On the disability sub-scales, physical role limitation, vitality, social functioning, emotional role limitation, and mental health were significantly lower in patient group than normal control group. While Cluster A was not related to any disability subscale, Cluster B had a positive correlation with vitality and mental health, whereas Cluster C and Cluster NOS had a negative correlation with emotional role limitation. Only the emotional role limitation predicts the presence of depression, whereas only self-defeating, obsessive, paranoid, and passive aggressive personality predict the emotional role limitation. Patients with MDD have personality and disability problems. PDs in depression contribute to disability. Our results demonstrated that the emotional role limitation is the unique sub-scale that predicts the MDD group.

    Full Text Available Background: Posttraumatic stress disorder (PTSD and major depressive disorder (MDD frequently co-occur after traumatic experiences and share neurocognitive disturbances in verbal memory and executive functioning. However, few attempts have been made to systematically assess the role of a comorbid MDD diagnosis in neuropsychological studies in PTSD. Objective: The purpose of the current study is to investigate neurocognitive deficits in PTSD patients with and without MDD. We hypothesized that PTSD patients with comorbid MDD (PTSD+MDD would have significantly lower performance on measures of verbal memory and executive functioning than PTSD patients without MDD (PTSD–MDD. Method: Participants included in this study were 140 treatment-seeking outpatients who had a diagnosis of PTSD after various single traumatic events and participated in a randomized controlled trial comparing different treatment types. Baseline neuropsychological data were compared between patients with PTSD+MDD (n=84 and patients with PTSD–MDD (n=56. Results: The PTSD+MDD patients had more severe verbal memory deficits in learning and retrieving words than patients with PTSD alone. There were no differences between the groups in recall of a coherent paragraph, recognition, shifting of attention, and cognitive interference. Conclusions: The results of this study suggest that a more impaired neurocognitive profile may be associated with the presence of comorbid MDD, with medium-sized group differences for verbal memory but not for executive functioning. From a clinical standpoint, being aware that certain verbal memory functions are more restricted in patients with comorbid PTSD and MDD may be relevant for treatment outcome of trauma-focused psychotherapy.

    It is known that the onset, progression, and prognosis of major depressive disorder are affected by interactions between a number of factors. This study investigated how childhood abuse, personality, and stress of life events were associated with symptoms of depression in depressed people. Patients with major depressive disorder (N = 113, 58 women and 55 men) completed the Beck Depression Inventory-II (BDI-II), the Neuroticism Extroversion Openness Five Factor Inventory (NEO-FFI), the Child Abuse and Trauma Scale (CATS), and the Life Experiences Survey (LES), which are self-report scales. Results were analyzed with correlation analysis and structural equation modeling (SEM), by using SPSS AMOS 21.0. Childhood abuse directly predicted the severity of depression and indirectly predicted the severity of depression through the mediation of personality. Negative life change score of the LES was affected by childhood abuse, however it did not predict the severity of depression. This study is the first to report a relationship between childhood abuse, personality, adulthood life stresses and the severity of depression in depressed patients. Childhood abuse directly and indirectly predicted the severity of depression. These results suggest the need for clinicians to be receptive to the possibility of childhood abuse in patients suffering from depression. SEM is a procedure used for hypothesis modeling and not for causal modeling. Therefore, the possibility of developing more appropriate models that include other variables cannot be excluded.

    Objective was to study the effect of splenectomy in patients with thalassemia major on the cardiovascular system through echocardiographic study. A prospective, cross-sectional study was carried out from December 2006 to December 2007. Patients from the Thalassemia Center in the Maternity and Children's Hospital, Madina, Kingdom of Saudi Arabia, were screened by means of history, physical examination, laboratory studies and echocardiography. Fifty-seven patients were studied: 36 were non-splenectomized, while 21 were surgically splenectomized. The 2 study groups were well matched for age, gender, height and weight. The total amount of blood given previous year (6577+-206.9 ml versus 5390.5+-220.2 ml, p=0.0005) and the annual transfusion index (200.9+-11.3 ml versus 134.1+-7.3, p=0.0001) were significantly lower in the splenectomized group. There was no significant difference between 2 groups regarding laboratory studies. Left ventricular systolic function shows no difference regarding fraction shortening between the 2 groups. The mitral valve E/A ratio was significantly higher in the splenectomized group (1.6+-0.2 versus1.4+-0.2, p=0.02). The pulmonary artery pressure was higher in the splenectomized group (34.2+-9.1 versus 20.8+-9.2 mm Hg, p=0.0001). There was a significantly higher number of patients with pulmonary hypertension in the splenectomized group (14[66.7%] versus 6[1.7%], p=0.0004). Splenectomized patients with thalassemia major are at high risk of having impaired diastolic left ventricular function and pulmonary hypertension. (author)

    The Prospective Epidemiological Research on Functioning Outcomes Related to Major depressive disorder (PERFORM) study describes the course of depressive symptoms, perceived cognitive symptoms, and functional impairment over 2 years in outpatients with major depressive disorder (MDD) and investigates the patient-related factors associated with functional impairment. This was a 2-year observational study in 1,159 outpatients with MDD aged 18-65 years who were either initiating antidepressant monotherapy or undergoing their first switch of antidepressant. Functional impairment was assessed by the Sheehan Disability Scale and the Work Productivity and Activity Impairment questionnaire. Patients assessed depression severity using the nine-item Patient Health Questionnaire and severity of perceived cognitive symptoms using the five-item Perceived Deficit Questionnaire. To investigate which patient-related factors were associated with functional impairment, univariate analyses of variance were performed to identify relevant factors that were then included in multivariate analyses of covariance at baseline, month 2, months 6 and 12 combined, and months 18 and 24 combined. The greatest improvement in depressive symptoms, perceived cognitive symptoms, and functional impairment was seen immediately (within 2 months) following initiation or switch of antidepressant therapy, followed by more gradual improvement and long-term stabilization. Improvement in perceived cognitive symptoms was less marked than improvement in depressive symptoms during the acute treatment phase. Functional impairment in patients with MDD was not only associated with severity of depressive symptoms but also independently associated with severity of perceived cognitive symptoms when adjusted for depression severity throughout the 2 years of follow-up. These findings highlight the burden of functional impairment in MDD and the importance of recognizing and managing cognitive symptoms in daily practice.

    Automatic thoughts are measurable cognitive markers of the psychopathology and coping styles of individuals. This study measured and compared the automatic thoughts of patients with generalized anxiety disorder (GAD), major depressive disorder (MDD), and generalized social phobia (GSP). Fifty-two patients with GAD, 53 with MDD, and 50 with GSP and 52 healthy controls completed the validated Automatic Thoughts Questionnaire (ATQ) and a structured psychiatric interview. Patients with GAD, MDD, and GSP also completed the validated Generalized Anxiety Disorder-7 questionnaire, the Beck Depression Inventory (BDI), and the Liebowitz Social Anxiety Scale (LSAS) to determine the severity of their illnesses. All scales were completed before treatment and after diagnosis. The ATQ scores of all pairs of groups were compared. The ATQ scores of the GAD, MDD, and GSP groups were significantly higher than were those of the control group. We also found significant correlations among scores on the GAD-7, BDI, and LSAS. The mean age of patients with GSP was lower than was that of the other groups (30.90 ± 8.35). The significantly higher ATQ scores of the MDD, GAD, and GSP groups, compared with the control group, underscore the common cognitive psychopathology characterizing these three disorders. This finding confirms that similar cognitive therapy approaches should be effective for these patients. This study is the first to compare GAD, MDD, and GSP from a cognitive perspective.

    Full Text Available BackgroundAlterations of coagulation profile have been reported in patients with β-thalassaemia major (β-TM.MethodTo investigate this in the paediatric population, we studied haemostatic parameters in pre-transfusion blood samples from 50 non-splenectomised transfusion-dependent children with β-TM (mean age 6±2.5 years and in blood from 25 healthy controls.ResultsLaboratory evaluation showed thrombocytopenia in 40%, prolongation of prothrombin time (PT in 12% and prolongation of activated partial thromboplastin time (APTT in 6% of the patients. Mean values for PT, APTT and platelet count (PC were all raised in the patient population compared with the controls. The alteration of coagulation status was significant for PT (p value 0.05. No significant liner correlation could be identified between PT, APTT, PC of the patients and interval between transfusions (in days or days since last transfusion.ConclusionThe findings from this study suggest that a subclinical haemorrhagic tendency exists in patients with β-TM at a very early age. The intrinsic pathway appears to be more affected than the extrinsic pathway.

    The purpose of this study was to explore whether patients with Inflammatory Arthritis (IA) (Rheumatoid Arthritis (RA), Psoriatic Arthritis (PsA) or Ankylosing Spondylitis (AS)) would remain in remission following a reduction in biologic dosing frequency and to calculate the cost savings associated with dose reduction. This prospective non-blinded non-randomised study commenced in 2010. Patients with Inflammatory Arthritis being treated with a biologic agent were screened for disease activity. A cohort of those in remission according to standardized disease activity indices (DAS28 < 2.6, BASDAI < 4) was offered a reduction in dosing frequency of two commonly used biologic therapies (etanercept 50 mg once per fortnight instead of weekly, adalimumab 40 mg once per month instead of fortnightly). Patients were assessed for disease activity at 3, 6, 12, 18 and 24 months following reduction in dosing frequency. Cost saving was calculated. 79 patients with inflammatory arthritis in remission were recruited. 57% had rheumatoid arthritis (n = 45), 13% psoriatic arthritis (n = 10) and 30% ankylosing spondylitis (n = 24). 57% (n = 45) were taking etanercept and 43% (n = 34) adalimumab. The percentage of patients in remission at 24 months was 56% (n = 44). This resulted in an actual saving to the state of approximately 600,000 euro over two years. This study demonstrates the reduction in biologic dosing frequency is feasible in Inflammatory Arthritis. There was a considerable cost saving at two years. The potential for major cost savings in biologic usage should be pursued further.

    Prior studies show significant gaps in the informed decision-making process, a central goal of surgical care. These studies have been limited by their focus on low-risk decisions, single visits rather than entire consultations, or both. Our objectives were, first, to rate informed decision-making for major elective vascular surgery based on audiotapes of actual physician-patient conversations and, second, to compare ratings of informed decision-making for first visits to ratings for multiple visits by the same patient over time. We prospectively enrolled patients for whom vascular surgical treatment was a potential option at a tertiary care outpatient vascular surgery clinic. We audio-taped all surgeon-patient conversations, including multiple visits when necessary, until a decision was made. Using an existing method, we evaluated the transcripts for elements of decision-making, including basic elements (e.g., an explanation of the clinical condition), intermediate elements (e.g., risks and benefits) and complex elements (e.g., uncertainty around the decision). We analyzed 145 surgeon-patient consultations. Overall, 45% of consultations contained complex elements, whereas 23% did not contain the basic elements of decision-making. For the 67 consultations that involved multiple visits, ratings were significantly higher when evaluating all visits (50% complex elements) compared with evaluating only the first visit (33% complex elements, p decision-making over multiple visits yielded different results than analyzing decision-making for single visits.

    Depression is an important target of psychological assessment in patients with end-stage renal disease because it predicts their morbidity, mortality, and quality of life. We assessed the effectiveness of cognitive-behavioral therapy in chronic hemodialysis patients diagnosed with major depression by the Mini International Neuropsychiatric Interview (MINI). In a randomized trial conducted in Brazil, an intervention group of 41 patients was given 12 weekly sessions of cognitive-behavioral group therapy led by a trained psychologist over 3 months while a control group of 44 patients received the usual treatment offered in the dialysis unit. In both groups, the Beck Depression Inventory, the MINI, and the Kidney Disease and Quality of Life-Short Form questionnaires were administered at baseline, after 3 months of intervention or usual treatment, and after 9 months of follow-up. The intervention group had significant improvements, compared to the control group, in the average scores of the Beck Depression Inventory overall scale, MINI scores, and in quality-of-life dimensions that included the burden of renal disease, sleep, quality of social interaction, overall health, and the mental component summary. We conclude that cognitive-behavioral group therapy is an effective treatment of depression in chronic hemodialysis patients.

    Not all individuals treated for major depressive disorder (MDD) achieve recovery. This observational study examined the recovery rates in MDD patients and the patient characteristics associated with achieving recovery in a naturalistic clinical setting. Recovery was defined as having both clinical and functional remission. Data for this post hoc analysis were taken from a 24-week prospective, observational study that involved 1,549 MDD patients. Clinical remission was assessed using the 16-item Quick Inventory of Depressive Symptomatology Self-Report and functional remission through the Sheehan Disability Scale and no days of reduced productivity in the previous week. Generalized estimating equation regression models were used to examine the baseline factors associated with recovery during follow-up. Clinical and functional remission was achieved in 70.6% and 56.1% of the MDD patients, respectively. MDD patients who achieved recovery (52.1%) were significantly less likely to have impaired levels of functioning, concurrent medical or psychiatric conditions, low levels of education, or nonadherence to therapy at follow-up. The level of functioning during the index episode seems to be a better predictor of recovery than symptom severity. Therefore, the level of functioning should be considered while determining recovery from depression.

    Full Text Available Background: Survival after major trauma is considered to be time dependent. Efficient prehospital care with rapid transport is the norm in developed countries, which is not available in many lower middle and low-income countries. The aim of this study was to assess the effect of prehospital time and primary treatment given on survival of major trauma patients in a setting without prehospital care. Materials and Methods: This prospective observational study was carried out in a university hospital in Mumbai, from January to December 2014. The hospital has a trauma service but no organized prehospital care or defined interhospital transfer protocols. All patients with life- and/or limb-threatening injuries were included in the study. Injury time and arrival time were noted and the interval was defined as “prehospital time” for the directly arriving patients and as “time to tertiary care” for those transferred. Primary outcome measure was in-hospital death (or discharge. Results: Of 1181 patients, 352 were admitted directly from the trauma scene and 829 were transferred from other hospitals. In-hospital mortality was associated with age, mechanism and mode of injury, shock, Glasgow Coma Score <9, Injury Severity Score ≥16, need for intubation, and ventilatory support on arrival; but neither with prehospital time nor with time to tertiary care. Transferred patients had a significantly higher mortality (odds ratio = 1.869, 95% confidence interval = 1.233–2.561, P = 0.005 despite fewer patients with severe injury. Two hundred and ninety-four (35% of these needed airway intervention while 108 (13% needed chest tube insertion on arrival to the trauma unit suggesting inadequate care at primary facility. Conclusion: Mortality is not associated with prehospital time but with transfers from primary care; probably due to deficient care. To improve survival after major trauma, enhancement of resources for resuscitation and capacity building of on

    Decisions under risk and with outcomes that are delayed in time are ubiquitous in real life and can have a significant impact on the health and wealth of the decision-maker. Despite its potential relevance for real-world choices, the degree of aberrant risky and intertemporal decision-making in patients suffering from major depressive disorder (MDD) and posttraumatic stress disorder (PTSD) has received little attention to date. We used a case-control design to compare decision-making in healthy control subjects (N=16) versus untreated depressed subjects in a current major depressive episode (N=20). In order to examine how major depressive disorder (MDD) may impact decision-making, subjects made decisions over (1) risky outcomes and (2) delayed outcomes in the domain of gains and losses using choice paradigms from neuroeconomics. In a pre-planned analysis, depressed subjects were subdivided into those with primary PTSD along with comorbid MDD (MDD+PTSD) versus those with primary MDD without PTSD (MDD-only). Choice behavior was modeled via a standard econometric model of intertemporal choice, a quasi-hyperbolic temporal discounting function, which was estimated for each subject group separately. Under conditions of potential gain, depressed subjects demonstrated greater discounting for gains across all time frames compared to controls. In the realm of losses, both subgroups of depressed subjects discounted more steeply than controls for short time frames. However, for delayed losses ranging from >1-10 years, MDD+PTSD subjects showed shallower discounting rates relative to MDD-only subjects, who continued to discount future losses steeply. Risk attitudes did not contribute to differences in intertemporal choice. Depressed patients make choices that minimize current pain and maximize current reward, despite severe later consequences or lost opportunities. Anxiety associated with PTSD may serve as a partially protective factor in decision-making about long

    Major depressive disorder (MDD) is an important and highly prevalent mental disorder characterized by anhedonia and a lack of interest in everyday activities. Additionally, patients with MDD appear to have deficits in various cognitive abilities. Although a number of studies investigating the central auditory processing of low-level sound features in patients with MDD have demonstrated that this population exhibits impairments in automatic processing, the influence of emotional voice processing has yet to be addressed. To explore the automatic processing of emotional prosodies in patients with MDD, we analyzed the ability to detect automatic changes using event-related potentials (ERPs). This study included 18 patients with MDD and 22 age- and sex-matched healthy controls. Subjects were instructed to watch a silent movie but to ignore the afferent acoustic emotional prosodies presented to both ears while continuous electroencephalographic activity was synchronously recorded. Prosodies included meaningless syllables, such as "dada" spoken with happy, angry, sad, or neutral tones. The mean amplitudes of the ERPs elicited by emotional stimuli and the peak latency of the emotional differential waveforms were analyzed. The sad MMN was absent in patients with MDD, whereas the happy and angry MMN components were similar across groups. The abnormal sad emotional MMN component was not significantly correlated with the HRSD-17 and HAMA scores, respectively. The data indicate that patients with MDD are impaired in their ability to automatically process sad prosody, whereas their ability to process happy and angry prosodies remains normal. The dysfunctional sad emotion-related MMN in patients with MDD were not correlated with depression symptoms. The blunted MMN of sad prosodies could be considered a trait of MDD.

    Although patients with major depressive disorder (MDD) have dysfunctions in cognitive behaviors and the regulation of emotions, the underlying brain dynamics of the pathophysiology are unclear. Therefore, nonlinear techniques can be used to understand the dynamic behavior of the EEG signals of MDD patients. To investigate and clarify the dynamics of MDD patients׳ brains during different emotional states, EEG recordings were analyzed using nonlinear techniques. The purpose of the present study was to assess whether there are different EEG complexities that discriminate between MDD patients and healthy controls during emotional processing. Therefore, nonlinear parameters, such as Katz fractal dimension (KFD), Higuchi fractal dimension (HFD), Shannon entropy (ShEn), Lempel-Ziv complexity (LZC) and Kolmogorov complexity (KC), were computed from the EEG signals of two groups under different experimental states: noise (negative emotional content) and music (positive emotional content) periods. First, higher complexity values were generated by MDD patients relative to controls. Significant differences were obtained in the frontal and parietal scalp locations using KFD (pemotional bias was demonstrated by their higher brain complexities during the noise period than the music stimulus. Additionally, we found that the KFD, HFD and LZC values were more sensitive in discriminating between patients and controls than the ShEn and KC measures, according to the results of ANOVA and ROC calculations. It can be concluded that the nonlinear analysis may be a useful and discriminative tool in investigating the neuro-dynamic properties of the brain in patients with MDD during emotional stimulation.

    Testosterone may have a role distinct from cortisol in the pathophysiology of depression. The hypothalamus-pituitary-adrenal (HPA) axis affects the functions of sex steroid hormones through interaction with corticotropin-releasing hormone (CRH) and gonadotropin-releasing hormone (GnRH). The objective of this study was to investigate differences in serum levels of testosterone and cortisol in male and female patients with major depressive disorder (MDD). Participants included 87 inpatients with MDD at Juntendo University Koshigaya Hospital. Serum levels of testosterone and cortisol were assessed at admission. Matched controls included 128 healthy individuals. Data from MDD patients and controls were compared separately for men and women. Correlations between serum hormone levels and scores on the Hamilton Rating Scale for Depression (HAM-D) of patients were assessed by sex. Effects of various factors on testosterone and cortisol were analyzed using multiple regression analysis. In male patients with MDD, a significant negative correlation was seen between testosterone levels and the "retardation" score of HAM-D. However, serum testosterone levels were not significantly different in either male or female MDD patients compared with controls. Serum testosterone was negatively associated with the number of depressive episodes in male patients with MDD. Serum cortisol levels in female patients were significantly increased compared with female controls with no significant correlations between cortisol levels and HAM-D scores. The negative correlation between the sub-score of the HAM-D and testosterone may be associated with the biological pathophysiology of male depression. Findings of serum cortisol levels in women may suggest distinct characteristics of these hormones in men and women with MDD.

    East Asian countries have high suicide rates. However, little is known about clinical and sociodemographic factors associated with suicidality in Asian populations. The aim of this study was to evaluate the factors associated with suicidality in patients with major depressive disorder (MDD) from six Asian countries. The study cohort consisted of 547 outpatients with MDD. Patients presented to study sites in China (n = 114), South Korea (n = 101), Malaysia (n = 90), Singapore (n = 40), Thailand (n = 103), and Taiwan (n = 99). All patients completed the Mini-International Neuropsychiatric Interview (MINI), the Montgomery-Asberg Depression Rating Scale (MADRS), the Global Severity Index(SCL-90R), the Fatigue Severity Scale, the 36-item short-form health survey, the Sheehan Disability Scale, and the Multidimensional Scale of Perceived Social Support (MSPSS). Patients were classified as showing high suicidality if they scored ≥ 6 on the MINI suicidality module. Multivariate logistic regression analysis was used to examine sociodemographic and clinical factors related to high suicidality. One hundred and twenty-five patients were classed as high suicidality. Unemployed status (adjusted odds ratio [OR] 2.43, p < 0.01), MADRS score (adjusted OR 1.08), p < 0.001, and GSI (SCL-90R) score (adjusted OR 1.06, p < 0.01) were positively related to high suicidality. Hindu (adjusted OR 0.09, p < 0.05) or Muslim (adjusted OR 0.21, p < 0.001) religion and MSPSS score (adjusted OR 0.82, p < 0.05) were protective against high suicidality. A variety of sociodemographic and clinical factors were associated with high suicidality in Asian patients with MDD. These factors may facilitate the identification of MDD patients at risk of suicide.

Legumes are important food allergens but their prevalence may vary among different populations. The present study identifies sensitization to common legumes among Indian population, characterizes allergens of kidney bean and establishes its cross reactivity with other legumes. METHODOLOGY: Patients (n = 355 with history of legume allergy were skin prick tested (SPT with 10 legumes. Specific IgE (sIgE and total IgE were estimated in sera by enzyme-linked immunosorbent assay. Characterization of kidney bean allergens and their cross reactivity was investigated by immunobiochemical methods. Identification of major allergens of kidney bean was carried out by mass spectrometry. PRINCIPAL FINDINGS: Kidney bean exhibited sensitization in 78 (22.0% patients followed by chickpea 65 (18.0% and peanut 53 (15%. SPT positive patients depicted significantly elevated sIgE levels against different legumes (r = 0.85, p<0.0001. Sera from 30 kidney bean sensitive individuals exhibited basophil histamine release (16-54% which significantly correlated with their SPT (r = 0.83, p<0.0001 and sIgE (r = 0.99, p<0.0001. Kidney bean showed eight major allergens of 58, 50, 45, 42, 40, 37, 34 and 18 kDa on immunoblot and required 67.3±2.51 ng of homologous protein for 50% IgE inhibition. Inhibition assays revealed extensive cross reactivity among kidney bean, peanut, black gram and pigeon pea. nLC-MS/MS analysis identified four allergens of kidney bean showing significant matches with known proteins namely lectin (phytohemagglutinin, phaseolin, alpha-amylase inhibitor precursor and group 3 late embryogenesis abundant protein. CONCLUSION/SIGNIFICANCE: Among legumes, kidney bean followed by chick pea and peanut are the major allergic triggers in asthma and rhinitis patients in India

    This study aims to assess the correlates of stigma toward mental illness among patients diagnosed with major depressive disorder (MDD). One hundred and sixty one Jordanian outpatients suffering from MDD completed the study. Participants completed the demographic questionnaire, the Center for Epidemiological Studies for the intensity of depression, and the Devaluation-Discrimination Scale to assess stigma. Participants reported a moderate level of perceived stigma toward mental illness. Age, perceived pain, the number of relapses, and severity of depressive symptoms were significantly correlated with stigma toward mental illness among the study sample. The severity of depressive symptoms was the strongest correlate of stigma toward mental illness. Factors associated with stigma toward mental illness should be carefully considered when implementing anti-stigma programs for patients. © 2017 Wiley Periodicals, Inc.

    Major depressive disorder (MDD) and smoking are major public health problems and epidemiologically strongly associated. However, the relationship between smoking and depression and whether this is influenced by common confounding factors remain unclear, in part due to limited longitudinal data on covariation. In the Vantaa Depression Study, psychiatric out- and inpatients with DSM-IV MDD and aged 20-59 years at were followed from baseline to 6 months, 18 months, and 5 years. We investigated course of depression, smoking, and comorbid alcohol-use disorders among the 214 patients (79.6% of 269) participating at least three time points; differences between smoking versus nonsmoking patients, and covariation of MDD, smoking, and alcohol-use disorders. Overall, 31.3% of the patients smoked regularly, 41.1% intermittently, and 27.6% never. Smokers were younger, had more alcohol-use disorders and Cluster B and C personality disorder symptoms, a higher frequency of lifetime suicide attempts, higher neuroticism, smaller social networks, and lower perceived social support than never smokers. Smoking and depression had limited longitudinal covariation. Depression, smoking, and alcohol-use disorders all exhibited strong autoregressive tendencies. Among adult psychiatric MDD patients, smoking is strongly associated with substance-use and personality disorders, which may confound research on the impact of smoking. Rather than depression or smoking covarying or predicting each other, depression, smoking, and alcohol-use disorders each have strong autoregressive tendencies. These findings are more consistent with common factors causing their association than either of the conditions strongly predisposing to the other. © 2013 Wiley Periodicals, Inc.

    Patients suffering from major depressive disorder (MDD) have been reported to have substantial long-lasting limitations in multiple domains of health-related quality of life (HRQoL). The thoughtful assessment of HRQoL and the impact of treatment response on HRQoL are emerging as important issues in the care of patients with major depressive disorder. One hundred and three patients meeting Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) criteria for MDD took fluoxetine (20 mg/d) for 6 weeks and were assessed by the Short Form 36 Health Survey (SF-36), the 17-item Hamilton Depression Rating (HAMD-17) and the Clinical Global Impression (CGI) scales. Relationships between SF-36 scores and depressive symptom severity and early change of these symptoms were tested. SF-36 component scores at week 6 were higher than those at baseline (all P ≤ 0.0058). Scores for general health were significantly higher in responders than non-responders (P = 0.0009). The overall HAMD-17 and CGI scores at 2- and 6-week follow-up were significantly lower than those at baseline (P ≤ 0.0001). Higher scores for anxiety/somatization were significantly associated with poorer SF-36 scores at baseline (P = 0.0001); role-physical scores at week 6 were positively correlated with reduction rate of anxiety/somatization in 2-week follow-up (P = 0.0002). Depressive symptom severity was associated with HRQoL in patients with MDD. HRQoL may vary with severity of depression and/or anxiety-somatization at baseline.

    The prevailing view of outcome of major depressive disorder (MDD), based on mostly inpatient cohorts sampled from tertiary centers, emphasizes chronicity and frequent recurrences. We investigated the long-term outcome of a regionally representative psychiatric MDD cohort comprising mainly outpatients. The Vantaa Depression Study included 163 patients with DSM-IV MDD (71.5% of those eligible) diagnosed using structured and semistructured interviews and followed up at 6 months, 18 months, and 5 years with a life chart between February 1, 1997, and April 30, 2004. The effects of comorbid disorders and other predictors on outcome were comprehensively investigated. Over the 5-year follow-up, 98.8% of patients achieved a symptom state below major depressive episode (MDE) criteria, and 88.4% reached full remission, with the median time to full remission being 11.0 months. Nearly one third (29.3%) had no recurrences, whereas 30.0% experienced 1, 12.9% experienced 2, and 27.9% experienced 3 or more recurrences. Preceding dysthymic disorder (p = .028), cluster C personality disorder (p = .041), and longer MDE duration prior to entry (p = .011) were the most significant predictors of longer time in achieving full remission. Severity of MDD and comorbidity, especially social phobia, predicted probability of, shorter time to, and number of recurrences. Previous literature on mostly inpatient MDD may have, by generalizing from patients with the most severe psychopathology, overemphasized chronicity of MDD. The long-term outcome of MDD in psychiatric care is variable, with about one tenth of patients having poor, one third having intermediate, and one half having favorable outcomes. In addition to known predictors, cluster C personality disorders and social phobia warrant further attention as predictors of MDD outcome among outpatients.

    In a previous study (unpublished), Emotiv headset was validated for capturing event-related potentials (ERPs) from normal subjects. In the present follow-up study, the signal quality of Emotiv headset was tested by the accuracy rate of discriminating Major Depressive Disorder (MDD) patients from the normal subjects. ERPs of 22 MDD patients and 15 normal subjects were induced by an auditory oddball task and the amplitude of N1, N2 and P3 of ERP components were specifically analyzed. The features of ERPs were statistically investigated. It is found that Emotiv headset is capable of discriminating the abnormal N1, N2 and P3 components in MDD patients. Relief-F algorithm was applied to all features for feature selection. The selected features were then input to a linear discriminant analysis (LDA) classifier with leave-one-out cross-validation to characterize the ERP features of MDD. 127 possible combinations out of the selected 7 ERP features were classified using LDA. The best classification accuracy was achieved to be 89.66%. These results suggest that MDD patients are identifiable from normal subjects by ERPs measured by Emotiv headset.

    Suicide rates are higher in East-Asians than other populations, and especially high in Koreans. However, little is known about suicidality risk and melancholic features in Asian patients with major depressive disorder (MDD). Drug-free MDD outpatients were included from 13 centers across five ethnicities consisting of Chinese (n=290), Korean (n=101), Thai (n=102), Indian (n=27), and Malay (n=27). All were interviewed using the Mini-International Neuropsychiatric Interview (M.I.N.I.), the Montgomery-Åsberg Depression Rating Scale (MADRS), and the Symptoms Checklist 90-Revised (SCL-90-R). Of 547 subjects, 177 MDD patients showed melancholic features (32.4%). These melancholic MDD patients revealed significantly higher suicidality risk (pdepression (pdifference in higher hostility. Adjusted odds ratios of melancholic features and hostility for moderate to high suicidality risk were 1.79 (95% CI=1.15-2.79) and 2.45 (95% CI=1.37-4.38), after adjusting for age, sex, education years, and depression severity. Post-hoc analyses showed that suicidality risk was higher in Korean and Chinese than that of Thai, Indian and Malay in MDD subjects with melancholic features, although depression severity showed no significant differences among the ethnicities. Suicidality risk is associated with both melancholic features and hostility and it shows cross-ethnic differences in Asian MDD patients, independent of depression severity.

    Cognitive deficits in major depressive disorder (MDD) patients have been described in numerous studies. However, few reports have aimed to describe cognitive deficits in the remitted state of MDD and the mediational effect of cognitive deficits on occupational outcome. The aim of the current review is to synthesize the literature on the mediating and moderating effects of specific domains of cognition on occupational impairment among people with remitted MDD. In addition, predictors of cognitive deficits found to be vocationally important will be examined. Upon examination of the extant literature, attention, executive function and verbal memory are areas of consistent impairment in remitted MDD patients. Cognitive domains shown to have considerable impact on vocational functioning include deficits in memory, attention, learning and executive function. Factors that adversely affect cognitive function related to occupational accommodation include higher age, late age at onset, residual depressive symptoms, history of melancholic/psychotic depression, and physical/psychiatric comorbidity, whereas higher levels of education showed a protective effect against cognitive deficit. Cognitive deficits are a principal mediator of occupational impairment in remitted MDD patients. Therapeutic interventions specifically targeting cognitive deficits in MDD are needed, even in the remitted state, to improve functional recovery, especially in patients who have a higher risk of cognitive deficit.

    Full Text Available Major depressive disorder (MDD is associated with changes in autonomic nervous system (ANS and cognitive impairment. Heart rate variability (HRV and Pulse pressure (PP parameters reflect influences of the sympathetic and parasympathetic nervous system. Cortisol exerts its greatest effect on the hippocampus, a brain area closely related to cognitive function. This study aims to examine the effect of HRV, PPG, salivary cortisol levels, and cognitive function in MDD patients by using noninvasive techniques. We have recruited MDD patients, diagnosed based on DSM-V-TR criteria compared with healthy control subjects. Their HRV and PP were measured by electrocardiogram (ECG and photoplethysmography (PPG. Salivary cortisol levels were collected and measured on the same day. MDD patients exhibited elevated values of mean HR, standard deviation of HR (SDHR, low frequency (LF power, low frequency/high frequency (LF/HF ratio, mean PP, standard deviation of pulse pressure (SDPP, and salivary cortisol levels. Simultaneously, they displayed lower values of mean of R-R intervals (mean NN, standard deviation of R-R intervals (SDNN, high frequency (HF power, and WCST scores. Results have shown that the ANS of MDD patients were dominated by the sympathetic activity and that they have cognitive deficits especially in the domain of executive functioning.

    Similar rates of remission from Major Depressive Disorder (MDD) have been documented between ethnic groups in response to antidepressant treatment. However, ethnic differences in functional outcomes, including patient-reported quality of life (QOL) and functioning, have not been well-characterized. We compared symptomatic and functional outcomes of antidepressant treatment in Hispanic and non-Hispanic patients with MDD. We analyzed 2280 nonpsychotic treatment-seeking adults with MDD who received citalopram monotherapy in Level 1 of the Sequenced Treatment Alternatives to Relieve Depression study. All subjects (239 Hispanic, 2041 non-Hispanic) completed QOL, functioning, and depressive symptom severity measures at entry and exit. Hispanic participants had significantly worse QOL scores at entry and exit (p depressive symptom severity or functioning. Both groups had significant improvements in depressive symptom severity, QOL, and functioning from entry to exit (all p values depressive symptom severity, greater QOL, and better functioning at exit compared to patients without private insurance. This study was a retrospective data analysis, and the Hispanic group was relatively small compared to the non-Hispanic group. Hispanic and non-Hispanic participants with MDD had similar responses to antidepressant treatment as measured by depressive symptom severity scores, quality of life, and functioning. Nevertheless, Hispanic patients reported significantly worse quality of life at entry. Copyright © 2017 Elsevier B.V. All rights reserved.

    To compare the effects of electrical stimulation of different acupoint combinations among postoperative bedridden elderly patients on hemorheology and deep venous blood flow velocity and investigate the.role of electrical stimulation against deep vein thrombosis (DVT). From November 2010 to October 2011, a total of 160 elderly bedridden patients after major surgery were divided into the conventional care group, invigorating and promoting Qi group, blood-activating and damp-eliminating group, and acupoint-combination stimulation group. Whole blood viscosity, plasma viscosity, D-dimer levels, lower limb skin temperature, lower limb circumference, and flow velocities of the external iliac vein, femoral vein, popliteal vein, and deep calf veins in all patients were documented and compared among the four groups. Whole blood viscosity, plasma viscosity, D-dimer levels, and lower limb circumference were significantly reduced in the blood-activating and damp-eliminating group compared with the conventional care group (P 0.05). Lower limb venous flow velocities were accelerated in the invigorating and promoting Qi group compared with the other groups, excluding the acupoint-combination stimulation group (P bedridden elderly patients were improved after combined electrical stimulation at Yinlingquan (SP 9) and Sanyinjiao (SP 6). Combined electrical stimulation at Zusanli (ST 36) and Taichong (LR 3), on the other hand, accelerated lower limb venous flow.

    Our study addressed distinct aspects of social problem solving in 28 hospitalized patients with Major Depressive Disorder (MDD) and 28 matched healthy controls. Three scenario-based tests assessed the ability to infer the mental states of story characters in difficult interpersonal situations, the capacity to freely generate good strategies for dealing with such situations and the ability to identify the best solutions among less optimal alternatives. Also, standard tests assessing attention, memory, executive function and trait empathy were administered. Compared to controls, MDD patients showed impaired interpretation of other peoples' sarcastic remarks but not of the mental states underlying other peoples' actions. Furthermore, MDD patients generated fewer strategies that were socially sensitive and practically effective at the same time or at least only socially sensitive. Overall, while the free generation of adequate strategies for difficult social situations was impaired, recognition of optimal solutions among alternatives was spared in MDD patients. Higher generation scores were associated with higher trait empathy and cognitive flexibility scores. We suggest that this specific pattern of impairments ought to be considered in the development of therapies addressing impaired social skills in MDD. Copyright © 2015 Elsevier Ireland Ltd.

    Previous literature established a link between major depressive disorder (MDD) and altered reward processing as well as between empathy and (observational) reward learning. The aim of the present study was to assess the effects of MDD on the electrophysiological correlates - the feedback-related negativity (FRN) and the P300 - of active and observational reward processing and to relate them to trait cognitive and affective empathy. Eighteen patients with MDD and 16 healthy controls performed an active and an observational probabilistic reward-learning task while event- related potentials were recorded. Also, participants were assessed with regard to self-reported cognitive and affective trait empathy. Relative to healthy controls, patients with MDD showed overall impaired learning and attenuated FRN amplitudes, irrespective of feedback valence and learning type (active vs. observational), but comparable P300 amplitudes. In the patient group, but not in controls, higher trait perspective taking scores were significantly correlated with reduced FRN amplitudes. The pattern of results suggests impaired prediction error processing and a negative effect of higher trait empathy on feedback-based learning in patients with MDD. Copyright © 2015 Elsevier B.V.

    Psychological variables, such as depression and anxiety, are known as independent risk factors for coronary artery disease (CAD), suggesting the interaction of psychological and physiological factors in the development of CAD. In the present study, we analyzed the possible association between depressive and anxiety symptoms and major atherosclerotic risk factors in patients with chest pain warranting coronary angiography. The patients without CAD (n=159) and those with CAD (n=155) were evaluated for the severity of depression and anxiety by the symptom scales; high scores indicate severe symptoms. Age, male/female ratio, prevalence of diabetes mellitus (DM), and depression level were significantly higher in the CAD group. Among a total of 314 patients with chest pain, the mean depression score was higher in patients with DM (16.01±8.12 vs 13.01±9.6, p=0.01) and those with hypercholesterolemia (15.43±9.61 vs 12.53±9.61, p=0.02). The mean anxiety score was also higher in patients with DM (20.81±12.85 vs 16.51±12.09, p=0.008), hypercholesterolemia (20.67±13.11 vs 15.29±11.36, p=0.002), or hypertension (20.74±12.94 vs 14.1±10.8, p=0.001). Thus, DM and hypercholesterolemia are associated with depression and anxiety, while hypertension is only related to anxiety. In contrast, smoking and family history of atherosclerosis are not related to depression and anxiety scores. These results suggest depression and anxiety symptoms may contribute to the development and progression of CAD, especially in patients with DM or hypercholesterolemia. (author)

    To describe radiologic findings of burn-associated persistent candidemia of the thorax. This study included 42 patients with major burns in whom blood culture had shown the presence for more than 24 hours of persistent candidemia. The duration of positive culture for candidiasis ranged from two to 67 days(mean, 15 days). Radiographic(n=42) and thin-section CT findings(n=13) were retrospectively analyzed. The onset, pattern, size, distribution and persistence of parenchymal abnormalities as well as the presence or absence of pleural effusions, mediastinal lymphadenopathy and cardiomegaly were assessed. On chest radiographs, positive findings were noticed in 61.9%(26/42) and on thin-section CT, in 76.9%(10/13). The most frequent radiographic finding was pulmonary nodule(s), observed in 14 patients(33.3%); in 13, these were bilateral. Bronchovascular bundle thickening(n=6, 14.3%), consolidation(n=4, 9.5%), cardiomegaly(n=6, 14.3%) and pleural effusion(n=4, 9.5%) were also observed. Those lesions appeared eight to 129 days(mean, 33 days) after the burn. Radiographic abnormalities persisted for seven to 115(mean, 35) days, regardless of the treatment. Thin-section CT showed parenchymal abnormalities in 10/13 patients(76.9%) and subpleural nodules of less than 1cm in diameter and without halo in all patients. Cardiomegaly, pleural effusion and mediastinal adenopathy were observed on CT in 5(38.5%), 4(30.8%) and 2(15.4%) of the 13 patients, respectively. In a high proportion of patients with burn-associated candidemia, chest radiograph and thin-section CT findings were positive. The most frequent radiographic parenchymal abnormality was multiple bilateral nodules.

    Early identification of patients with major depressive disorder (MDD) that cannot be managed by secondary mental health services and who require highly specialized mental healthcare could enhance need-based patient stratification. This, in turn, may reduce the number of treatment steps needed to achieve and sustain an adequate treatment response. The development of a valid tool to identify patients with MDD in need of highly specialized care is hampered by the lack of a comprehensive understanding of indicators that distinguish patients with and without a need for highly specialized MDD care. The aim of this study, therefore, was to systematically review studies on indicators of patients with MDD likely in need of highly specialized care. A structured literature search was performed on the PubMed and PsycINFO databases following PRISMA guidelines. Two reviewers independently assessed study eligibility and determined the quality of the identified studies. Three reviewers independently executed data extraction by using a pre-piloted, standardized extraction form. The resulting indicators were grouped by topical similarity, creating a concise summary of the findings. The systematic search of all databases yielded a total of 7,360 references, of which sixteen were eligible for inclusion. The sixteen papers yielded a total of 48 unique indicators. Overall, a more pronounced depression severity, a younger age of onset, a history of prior poor treatment response, psychiatric comorbidity, somatic comorbidity, childhood trauma, psychosocial impairment, older age, and a socioeconomically disadvantaged status were found to be associated with proxies of need for highly specialized MDD care. Several indicators are associated with the need for highly specialized MDD care. These indicators provide easily measurable factors that may serve as a starting point for the development of a valid tool to identify patients with MDD in need of highly specialized care.

    OBJECTIVE Health care education resources are increasingly available on the Internet. A majority of people reference these resources at one point or another. A threshold literacy level is needed to comprehend the information presented within these materials. A key component of health literacy is the readability of educational resources. The National Institutes of Health (NIH) and the American Medical Association have recommended that patient education materials be written between a 4th- and a 6th-grade education level. The authors assessed the readability of online patient education materials about brain aneurysms that have been published by several academic institutions across the US. METHODS Online patient education materials about brain aneurysms were downloaded from the websites of 20 academic institutions. The materials were assessed via 8 readability scales using Readability Studio software (Oleander Software Solutions), and then were statistically analyzed. RESULTS None of the patient education materials were written at or below the NIH's recommended 6th-grade reading level. The average educational level required to comprehend the texts across all institutions, as assessed by 7 of the readability scales, was 12.4 ± 2.5 (mean ± SD). The Flesch Reading Ease Scale classified the materials as "difficult" to understand, correlating with a college-level education or higher. An ANOVA test found that there were no significant differences in readability among the materials from the institutions (p = 0.215). CONCLUSIONS Brain aneurysms affect 3.2% of adults 50 years or older across the world and can cause significant patient anxiety and uncertainty. Current patient education materials are not written at or below the NIH's recommended 4th- to 6th-grade education level.

    Previous neuroimaging studies have revealed frontal and temporal functional abnormalities in patients with major depressive disorder (MDD) and a history of suicidal behavior. However, it is unknown whether multi-channel near-infrared spectroscopy (NIRS) signal changes among individuals with MDD are associated with a history of suicide attempts and a diathesis for suicidal behavior (impulsivity, hopelessness, and aggression). Therefore, we aimed to explore frontotemporal hemodynamic responses in depressed patients with a history of suicide attempts using 52-channel NIRS. We recruited 30 patients with MDD and a history of suicidal behavior (suicide attempters; SAs), 38 patient controls without suicidal behavior (non-attempters; NAs), and 40 healthy controls (HCs) matched by age, gender ratio, and estimated IQ. Regional hemodynamic responses during a verbal fluency task (VFT) were monitored using NIRS. Our results showed that severities of depression, impulsivity, aggression, and hopelessness were similar between SAs and NAs. Both patient groups had significantly reduced activation compared with HCs in the bilateral frontotemporal regions. Post hoc analyses revealed that SAs exhibited a smaller hemodynamic response in the left precentral gyrus than NAs and HCs. Furthermore, the reduced response in the left inferior frontal gyrus was negatively correlated with impulsivity level and hemodynamic responses in the right middle frontal gyrus were negatively associated with hopelessness and aggression in SAs but not in NAs and HCs. Our findings suggest that MDD patients with a history of suicide attempts demonstrate patterns of VFT-induced NIRS signal changes different from those demonstrated by individuals without a history of suicidal behaviors, even in cases where clinical symptoms are similar. NIRS has a relatively high time resolution, which may help visually differentiate SAs from NAs.

    Full Text Available Background Doppler echocardiographic studies of left ventricle (LV systolic and diastolic function in patients with β-Thalassemia Major (β-TM had shown different patterns of systolic and diastolic dysfunction. Aim This cross-sectional study was designed to study the LV systolic and diastolic function in patients with β-TM using Pulsed Doppler (PD and Tissue Doppler (TD echocardiography. Methods All patients were evaluated clinically and by echocardiography, The study included patients with β-TM (n = 38, age 15.7 ± 8.9 years compared with an age-matched control group (n = 38, age 15.9 ± 8.9 years. The pulse Doppler indices were normalized for age and heart rate. Results Compared with control patients, M-Mode showed that patients with β-TM have thicker LV septal wall index (0.659 ± 0.23 vs. 0.446 ± 0.219 cm, P ≤ 0.001, posterior wall index (0.659 ± 0.235 vs. 0.437 ± 0.214 cm, P ≤ 0.01, and larger LVEDD index is (3.99 ± 0.48 vs. 2.170 ± 0.57 mm. P = 0.035. Pulsed Doppler showed high LV trans-mitral E wave velocity (70.818 ± 10.139 vs. 57.532 ± 10.139, p = 0.027 and E/A ratio (1.54 vs. 1.23, P ≤ 0.01. The duration of Deceleration time (DT and isovolumic relaxation time (IVRT were significantly shorter in patients with β-TM (150.234 ± 20.0.23 vs. 167.123 ± 19.143 msec, P ≤ 0.01 and (60.647 ± 6.77 vs. 75.474 ± 5.83 msec, P ≤ 0.001, respectively. The ratio of transmitral E wave velocity to the tissue Doppler E wave at the basal septal mitral annulus E/Em – was significantly higher in β-TM group (14.024 ± 2.29 vs. 12.132 ± 1.82, P ≤ 0.01. The Tissue Doppler systolic velocity (Sm and the early diastolic velocity (Em were significantly lower in β-TM group compared to control (4.31 ± 1.2 cm/s vs. 6.95 ± 2.1, P ≤ 0.01 and 4.31 ± 2.7 cm/s vs. 5.82 ± 2.5, P ≤ 0.01 respectively. The tricuspid valve velocity was significantly higher than controls (2.993 ± 0.569 vs. 1.93 ± 0.471 m/sec, respectively, P ≤ 0

    Full Text Available Abstract Aim We aimed to define reference ranges for right ventricular (RV volumes, ejection fraction (EF in thalassemia major patients (TM without myocardial iron overload. Methods and results RV volumes, EF and mass were measured in 80 TM patients who had no myocardial iron overload (myocardial T2* > 20 ms by cardiovascular magnetic resonance. All patients were receiving deferoxamine chelation and none had evidence of pulmonary hypertension or other cardiovascular comorbidity. Forty age and sex matched healthy non-anemic volunteers acted as controls. The mean RV EF was higher in TM patients than controls (males 66.2 ± 4.1% vs 61.6 ± 6%, p = 0.0009; females 66.3 ± 5.1% vs 62.6 ± 6.4%, p = 0.017, which yielded a raised lower threshold of normality for RV EF in TM patients (males 58.0% vs 50.0% and females 56.4% vs 50.1%. RV end-diastolic volume index was higher in male TM patients (mean 98.1 ± 17.3 mL vs 88.4 ± 11.2 mL/m2, p = 0.027, with a higher upper limit (132 vs 110 mL/m2 but this difference was of borderline significance for females (mean 86.5 ± 13.6 mL vs 80.3 ± 12.8 mL/m2, p = 0.09, with upper limit of 113 vs 105 mL/m2. The cardiac index was raised in TM patients (males 4.8 ± 1.0 L/min vs 3.4 ± 0.7 L/min, p Conclusion The normal ranges for functional RV parameters in TM patients with no evidence of myocardial iron overload differ from healthy non-anemic controls. The new reference RV ranges are important for determining the functional effects of myocardial iron overload in TM patients.

    Full Text Available Mood disorders consist of two etiologically related, but distinctly treated illnesses, major depressive disorder (MDD and bipolar disorder (BPD. These disorders share similarities in their clinical presentation, and thus show high rates of misdiagnosis. Recent research has revealed significant transcriptional differences within the inflammatory cytokine pathway between MDD patients and controls, and between BPD patients and controls, suggesting this pathway may possess important biomarker properties. This exploratory study attempts to identify disorder-specific transcriptional biomarkers within the inflammatory cytokine pathway, which can distinguish between control subjects, MDD patients and BPD patients. This is achieved using RNA extracted from subject blood and applying synthesized complementary DNA to quantitative PCR arrays containing primers for 87 inflammation-related genes. Initially, we use ANOVA to test for transcriptional differences in a 'discovery cohort' (total n = 90 and then we use t-tests to assess the reliability of any identified transcriptional differences in a 'validation cohort' (total n = 35. The two most robust and reliable biomarkers identified across both the discovery and validation cohort were Chemokine (C-C motif ligand 24 (CCL24 which was consistently transcribed higher amongst MDD patients relative to controls and BPD patients, and C-C chemokine receptor type 6 (CCR6 which was consistently more lowly transcribed amongst MDD patients relative to controls. Results detailed here provide preliminary evidence that transcriptional measures within inflammation-related genes might be useful in aiding clinical diagnostic decision-making processes. Future research should aim to replicate findings detailed in this exploratory study in a larger medication-free sample and examine whether identified biomarkers could be used prospectively to aid clinical diagnosis.

    The purpose of this study was to evaluate the effect of neurofeedback on depressive symptoms and electrophysiological disturbances in patients with major depressive disorder. We recruited participants suffering from depression to evaluate efficacy of left prefrontal beta with alpha/theta training. An 8-week, prospective, open-label study was undertaken. Twenty participants were recruited. The treatment protocol was twice or three times a week training of beta at F3 with alpha/theta at Pz for 8 weeks. When every visit, patients were received beta training for 30 min, and then alpha/theta training for 30 min. Baseline, 4 and 8 week scores of; the Hamilton rating scale for Depression (HAM-D), the Hamilton rating scale for Anxiety (HAM-A), the Beck Depression Inventory (BDI)-II, the Beck Anxiety Inventory (BAI), Clinical global impression-severity (CGI-S), and pre- and post-treatment resting state EEGs were compared. Interhemispheric alpha power asymmetry (A score) was computed for homologous sites F3-F4. Pre- and post-training clinical assessments revealed significant improvements in HAM-D, HAM-A, BDI, and CGI-S scores. Cumulative response rates by HAM-D were 35.0 and 75.0 % at 4 and 8 weeks, respectively, corresponding cumulative remission rates by HAM-D were 15.0 and 55.0 %, respectively. No significant differences were found between pre- and post-treatment A score. Neurofeedback treatment could improve depressive symptoms significantly. In addition, anxiety symptoms and clinical illness severity decreased significantly after neurofeedback treatment. Despite its several limitations, such as, small sample size and lack of a control group, this study suggested neurofeedback has significant effects in patients with major depressive disorder.

Mean age was 42 years, 68% were female. There were 113 (9% current smokers and 326 (25% ex-smokers. Seven percent of the staff were current smokers compared with 19% of the patients. The Fagerstrom test showed that 47% of patients who smoked were moderately nicotine dependent compared with 21% of staff. A third of the staff who smoked did not anticipate health problems related to smoking. Most patients (79% who smoked disagreed that their current health problems were related to smoking. Although more than half of the current smokers preferred pharmacotherapy, one in two of them did not prefer behavior counseling; with consistent results among staff and patients. Multivariate analyses showed that patients were three times more likely (odds ratio 3.0, 95% confidence interval 1.9–4.7 to smoke than staff.Conclusion: This study reports lower prevalence of smoking among hospital staff compared with national data.

    Full Text Available One barrier to interpreting past studies of cognition and Major Depressive Disorder (MDD has been the failure in many studies to adequately dissociate the effects of MDD from the potential cognitive side effects of Selective Serotonin Reuptake Inhibitors (SSRI use. To better understand how remediation of depressive symptoms affects cognitive function in MDD, we evaluated three groups of subjects: medication-naïve patients with MDD, medicated patients with MDD receiving the SSRI paroxetine and healthy control subjects. All were administered a category-learning task that allows for dissociation between learning from positive feedback (reward versus learning from negative feedback (punishment. Healthy subjects learned significantly better from positive feedback than medication-naïve and medicated MDD groups, whose learning accuracy did not differ significantly. In contrast, medicated patients with MDD learned significantly less from negative feedback than medication-naïve patients with MDD and healthy subjects, whose learning accuracy was comparable. A comparison of subject’s relative sensitivity to positive versus negative feedback showed that both the medicated MDD and healthy control groups conform to Kahneman and Tversky’s (1979 Prospect Theory, which expects losses (negative feedback to loom psychologically slightly larger than gains (positive feedback. However, medicated MDD and HC profiles are not similar, which indicates that the state of medicated MDD is not ‘normal’ when compared to HC, but rather balanced with less learning from both positive and negative feedback. On the other hand, medication-naïve patients with MDD violate Prospect Theory by having significantly exaggerated learning from negative feedback. This suggests that SSRI antidepressants impair learning from negative feedback, while having negligible effect on learning from positive feedback. Overall, these findings shed light on the importance of dissociating the

    Detection of IgE to recombinant Hymenoptera venom allergens has been suggested to improve the diagnostic precision in Hymenoptera venom allergy. However, the frequency of sensitization to the only available recombinant honeybee venom (HBV) allergen, rApi m 1, in patients with HBV allergy is limited, suggesting that additional HBV allergens might be of relevance. We performed an analysis of sensitization profiles of patients with HBV allergy to a panel of HBV allergens. Diagnosis of HBV allergy (n = 144) was based on history, skin test results, and allergen-specific IgE levels to HBV. IgE reactivity to 6 HBV allergens devoid of cross-reactive carbohydrate determinants (CCD) was analyzed by ImmunoCAP. IgE reactivity to rApi m 1, rApi m 2, rApi m 3, nApi m 4, rApi m 5, and rApi m 10 was detected in 72.2%, 47.9%, 50.0%, 22.9%, 58.3%, and 61.8% of the patients with HBV allergy, respectively. Positive results to at least 1 HBV allergen were detected in 94.4%. IgE reactivity to Api m 3, Api m 10, or both was detected in 68.0% and represented the only HBV allergen-specific IgE in 5% of the patients. Limited inhibition of IgE binding by therapeutic HBV and limited induction of Api m 3- and Api m 10-specific IgG4 in patients obtaining immunotherapy supports recent reports on the underrepresentation of these allergens in therapeutic HBV preparations. Analysis of a panel of CCD-free HBV allergens improved diagnostic sensitivity compared with use of rApi m 1 alone, identified additional major allergens, and revealed sensitizations to allergens that have been reported to be absent or underrepresented in therapeutic HBV preparations.

This observational study examined the recovery rates in MDD patients and the patient characteristics associated with achieving recovery in a naturalistic clinical setting. Recovery was defined as having both clinical and functional remission. Data for this post hoc analysis were taken from a 24-week prospective, observational study that involved 1,549 MDD patients. Clinical remission was assessed using the 16-item Quick Inventory of Depressive Symptomatology Self-Report and functional remission through the Sheehan Disability Scale and no days of reduced productivity in the previous week. Generalized estimating equation regression models were used to examine the baseline factors associated with recovery during follow-up. Clinical and functional remission was achieved in 70.6% and 56.1% of the MDD patients, respectively. MDD patients who achieved recovery (52.1% were significantly less likely to have impaired levels of functioning, concurrent medical or psychiatric conditions, low levels of education, or nonadherence to therapy at follow-up. The level of functioning during the index episode seems to be a better predictor of recovery than symptom severity. Therefore, the level of functioning should be considered while determining recovery from depression.

    Objective: To determine the problems faced by thalassemic patients in their personal, psychological and social life. Study Design: A cross-sectional multi-centre survey. Place and Duration of Study: Karachi, Lahore and Quetta Centres of Fatimid Foundation, from October 2009 to October 2010. Methodology: An indigenously developed Qualifty of Life (QoL) questionnaire modified from SF-36 questionnaire was administered to 101 transfusion dependent subjects suffering from thalassemia major. Variables were analyzed using SPSS version 15 for descriptive statistics. Results: The mean age of the subjects was 10.5 years ranging from 6 - 21 years. Less than one third of the patients felt that their health was slightly worse as compared to last year. Forty five (44%) of the patients felt loneliness due to their disease. Parents of 36 (35.6%) of the children at times did not allow their children to play because of their disease. Twenty eight (27.7%) stated difficulty in mingling with children of their age. Seventy one (70.3%) of the patients reported that at some or all times they were worried about their future life and career while 70 (69.3%) admitted being taken extra care of by their friends and 56 (55.4%) by their teachers. Conclusion: The quality of life of surveyed thalassemic patients was immensely affected. Having physical impairments, social stresses, financial burdens and problems with their education and career make them very much vulnerable to psychological trauma very early in their life. All of this creates a hindrance in their way of developing into autonomous functioning adults. (author)

Diabetes did not influence fracture risk, nor did rheumatic disorders. The risk was lower...... and associations may not be causal, it may be prudent to include dementia, ulcer disease, and Parkinson's disease to capture the risk of fractures on treatment. Lower risk in patients treated with glucocorticoids and in men probably reflects a lower treatment threshold related to guidelines.......Antiresorptive treatment reduces the risk of fractures, but most patients remain at elevated risk. We used health registers to identify predictors of new major osteoporotic fractures in patients adhering to alendronate. Risk factors showed a different pattern than in the general population...

    To identify brain cortical regions relevant to HIV-associated neurocognitive disorder (HAND) in HIV patients. HIV patients with HAND (n = 10), those with intact cognition (HIV-IC; n = 12), and age-matched, seronegative controls (n = 11) were recruited. All participants were male and underwent 3-dimensional T1-weighted imaging. Both vertex-wise and region of interest (ROI) analyses were performed to analyse cortical thickness. Compared to controls, both HIV-IC and HAND showed decreased cortical thickness mainly in the bilateral primary sensorimotor areas, extending to the prefrontal and parietal cortices. When directly comparing HIV-IC and HAND, HAND showed cortical thinning in the left retrosplenial cortex, left dorsolateral prefrontal cortex, left inferior parietal lobule, bilateral superior medial prefrontal cortices, right temporoparietal junction and left hippocampus, and cortical thickening in the left middle occipital cortex. Left retrosplenial cortical thinning showed significant correlation with slower information processing, declined verbal memory and executive function, and impaired fine motor skills. This study supports previous research suggesting the selective vulnerability of the primary sensorimotor cortices and associations between cortical thinning in the prefrontal and parietal cortices and cognitive impairment in HIV-infected patients. Furthermore, for the first time, we propose retrosplenial cortical thinning as a possible major contributor to HIV-associated cognitive impairment. (orig.)

    Cardiac tamponade is a medical emergency condition. Rapid diagnosis and determination of the etiology with epidemiologic consideration may lead to earlier treatment and improved survival. Occasionally, the etiology may be clearly related to a recognized underlying disease, but the possibility of unrelated etiologies should be considered. Pericarditis tuberculosis, a rare manifestation of extrapulmonary tuberculosis in a non-HIV patient, has to be deliberate as one of the etiology, especially in the endemic area. Here, we report a case of 28 years old male with β thalassemia major presented with excessive exertion breathlessness progressing to orthopnea. Sign of cardiac tamponade was identified from echocardiography which showed large pericardial effusion with swinging heart and right atrial systolic collapse. Pericardiocentesis was performed immediately, drained 870 ml of hemorrhagic fluid from inserted pigtail. The patient was treated with the anti-tuberculosis regimen and oral corticosteroid after real-time polymerase chain reaction of Mycobacterium tuberculosis positivity in pericardial fluid. MRI T2 confirmed no haemosiderosis in patient’s heart. After treatment, the patient responded well and showed clinical improvement.

    Patients with cervical spine injuries are a high-risk group, with the highest reported early mortality rate in spinal trauma. This cohort study investigated predictors for cervical spine injury in adult (≥ 16 years) major trauma patients using prospectively collected data of the Trauma Audit and Research Network from 1988 to 2009. Univariate and multivariate logistic regression analyses were used to determine predictors for cervical fractures/dislocations or cord injury. A total of 250,584 patients were analyzed. Median age was 47.2 years (interquartile range, 29.8-66.0) and Injury Severity Score 9 (interquartile range, 4-11); 60.2% were male. Six thousand eight hundred two patients (2.3%) sustained cervical fractures/dislocations alone. Two thousand sixty-nine (0.8%) sustained cervical cord injury with/without fractures/dislocations; 39.9% of fracture/dislocation and 25.8% of cord injury patients suffered injuries to other body regions. Age ≥ 65 years (odds ratio [OR], 1.45-1.92), males (females OR, 0.91; 95% CI, 0.86-0.96), Glasgow Coma Scale (GCS) score sports injuries (OR, 3.51; 95% CI, 2.87-4.31), road traffic collisions (OR, 3.24; 95% CI, 3.01-3.49), and falls >2 m (OR, 2.74; 95% CI, 2.53-2.97) were predictive for fractures/dislocations. Age sports injuries (OR, 4.42; 95% CI, 3.28-5.95), road traffic collisions (OR, 2.58; 95% CI, 2.26-2.94), and falls >2 m (OR, 2.24; 95% CI, 1.94-2.58) were predictors for cord injury. 3.5% of patients suffered cervical spine injury. Patients with a lowered GCS or systolic blood pressure, severe facial fractures, dangerous injury mechanism, male gender, and/or age ≥ 35 years are at increased risk. Contrary to common belief, head injury was not predictive for cervical spine involvement.

    Only one-third of patients with major depressive disorder (MDD) achieve remission with initial treatment. Consequently, current clinical practice relies on a "trial-and-error" approach to identify an effective treatment for each patient. The purpose of this report was to determine whether we could identify a set of clinical and biological parameters with potential clinical utility for prescription of exercise for treatment of MDD in a secondary analysis of the Treatment with Exercise Augmentation in Depression (TREAD) trial. Participants with nonremitted MDD were randomized to one of two exercise doses for 12 weeks. Participants were categorized as "remitters" (≤12 on the IDS-C), nonresponders (drop in IDS-C), or neither. The least absolute shrinkage and selection operator (LASSO) and random forests were used to evaluate 30 variables as predictors of both remission and nonresponse. Predictors were used to model treatment outcomes using logistic regression. Of the 122 participants, 36 were categorized as remitters (29.5%), 56 as nonresponders (45.9%), and 30 as neither (24.6%). Predictors of remission were higher levels of brain-derived neurotrophic factor (BDNF) and IL-1B, greater depressive symptom severity, and higher postexercise positive affect. Predictors of treatment nonresponse were low cardiorespiratory fitness, lower levels of IL-6 and BDNF, and lower postexercise positive affect. Models including these predictors resulted in predictive values greater than 70% (true predicted remitters/all predicted remitters) with specificities greater than 25% (true predicted remitters/all remitters). Results indicate feasibility in identifying patients who will either remit or not respond to exercise as a treatment for MDD utilizing a clinical decision model that incorporates multiple patient characteristics. © 2017 Wiley Periodicals, Inc.

    Full Text Available While a link between inflammation and the development of neuropsychiatric disorders, including major depressive disorder (MDD is supported by a growing body of evidence, little is known about the contribution of aberrant adaptive immunity in this context. Here, we conducted in-depth characterization of T cell phenotype and T cell receptor (TCR repertoire in MDD. For this cross-sectional case–control study, we recruited antidepressant-free patients with MDD without any somatic or psychiatric comorbidities (n = 20, who were individually matched for sex, age, body mass index, and smoking status to a non-depressed control subject (n = 20. T cell phenotype and repertoire were interrogated using a combination of flow cytometry, gene expression analysis, and next generation sequencing. T cells from MDD patients showed significantly lower surface expression of the chemokine receptors CXCR3 and CCR6, which are known to be central to T cell differentiation and trafficking. In addition, we observed a shift within the CD4+ T cell compartment characterized by a higher frequency of CD4+CD25highCD127low/− cells and higher FOXP3 mRNA expression in purified CD4+ T cells obtained from patients with MDD. Finally, flow cytometry-based TCR Vβ repertoire analysis indicated a less diverse CD4+ T cell repertoire in MDD, which was corroborated by next generation sequencing of the TCR β chain CDR3 region. Overall, these results suggest that T cell phenotype and TCR utilization are skewed on several levels in patients with MDD. Our study identifies putative cellular and molecular signatures of dysregulated adaptive immunity and reinforces the notion that T cells are a pathophysiologically relevant cell population in this disorder.

    Sleep disturbance is a common complaint in major depressive disorder (MDD) including impairment of both subjective and objective parameters. All antidepressants affect sleep architecture and quality. This trial was designed to compare the effects of short-term use of citalopram with fluoxetine on sleep quality (SQ) of patients with MDD based on Diagnostic and Statistical Manual for Mental Disorders - Text Revision 4th edition (DSM-IV-TR) criteria. Patients who met the study criteria entered this open-label study. Sleep quality and depression severity were evaluated by using Pittsburgh Sleep Quality Index (PSQI) and Beck Depression Inventory-II (BDI-II), respectively. Patients could not have received any antidepressant for at least one month prior entering the study. Subjects were assigned to receive either fluoxetine or citalopram for 8 weeks. The relationships between SQ and severity of depression were also studied at weeks 4 and 8. Data was analyzed by using SPSS 11.5 version. Nineteen patients received fluoxetine 20-40 mg/day and 21 received citalopram 20-40 mg/day. After 4 and 8 weeks treatment with both fluoxetine and citalopram, significant improvements in SQ were noted in both groups. However, no significant difference between the two groups was observed. Additionally, a significant and positive correlation between improvements in SQ and depression was noted after 8 weeks treatment with citalopram but not with fluoxetine. This study noted that both citalopram and fluoxetine improved SQ in outpatients with MDD after 8 weeks without any significant difference between the 2 groups.

    In this study, we explored the presentation of clinical depression in Java, Indonesia. Interviews were conducted with 20 Javanese patients (male and female) with major depressive disorder from both lower and higher socioeconomic levels. The recruited participants came from provincial and private mental health hospitals in the cities of Solo, Yogykarta (Jogja), Jakarta, and Malang on the island of Java, Indonesia. Concept mapping methodology using multidimensional scaling and hierarchical cluster analysis was used to identify underlying themes in the expression of depressive phenomena in this Indonesian population. The results identified themes that grouped into six clusters: interpersonal relationships, hopelessness, physical/somatic, poverty of thought, discourage, and defeat. Findings give support to the view that culture influences the expression of Indonesian depressive phenomenology, which nevertheless has some common roots with Western clinical pictures of the disorder. Cultural influences may mask symptoms of the disorder to clinicians. Diagnostic and assessment tools must be carefully selected to ensure they address culturally specific expressions of depression.

    The definition of major bleeding varies between studies on surgical patients, particularly regarding the criteria for surgical wound-related bleeding. This diversity contributes to the difficulties in comparing data between trials. The Scientific and Standardization Committee (SSC), through its subcommittee on Control of Anticoagulation, of the International Society on Thrombosis and Haemostasis has previously published a recommendation for a harmonized definition of major bleeding in non-surgical studies. That definition has been adopted by the European Medicines Agency and is currently used in several non-surgical trials. A preliminary proposal for a parallel definition for surgical studies was presented at the 54(th) Annual Meeting of the SSC in Vienna, July 2008. Based on those discussions and further consultations with European and North American surgeons with experience from clinical trials a definition has been developed that should be applicable to all agents that interfere with hemostasis. The definition and the text that follows have been reviewed and approved by relevant co-chairs of the subcommittee and by the Executive Committee of the SSC. The intention is to seek approval of this definition from the regulatory authorities to enhance its incorporation into future clinical trial protocols.

    To estimate the frequency of mixed states in patients diagnosed with major depressive episode (MDE) according to conceptually different definitions and to compare their clinical validity. This multicenter, multinational cross-sectional Bipolar Disorders: Improving Diagnosis, Guidance and Education (BRIDGE)-II-MIX study enrolled 2,811 adult patients experiencing an MDE. Data were collected per protocol on sociodemographic variables, current and past psychiatric symptoms, and clinical variables that are risk factors for bipolar disorder. The frequency of mixed features was determined by applying both DSM-5 criteria and a priori described Research-Based Diagnostic Criteria (RBDC). Clinical variables associated with mixed features were assessed using logistic regression. Overall, 212 patients (7.5%) fulfilled DSM-5 criteria for MDE with mixed features (DSM-5-MXS), and 818 patients (29.1%) fulfilled diagnostic criteria for a predefined RBDC depressive mixed state (RBDC-MXS). The most frequent manic/hypomanic symptoms were irritable mood (32.6%), emotional/mood lability (29.8%), distractibility (24.4%), psychomotor agitation (16.1%), impulsivity (14.5%), aggression (14.2%), racing thoughts (11.8%), and pressure to keep talking (11.4%). Euphoria (4.6%), grandiosity (3.7%), and hypersexuality (2.6%) were less represented. In multivariate logistic regression analysis, RBDC-MXS was associated with the largest number of variables including diagnosis of bipolar disorder, family history of mania, lifetime suicide attempts, duration of the current episode > 1 month, atypical features, early onset, history of antidepressant-induced mania/hypomania, and lifetime comorbidity with anxiety, alcohol and substance use disorders, attention-deficit/hyperactivity disorder, and borderline personality disorder. Depressive mixed state, defined as the presence of 3 or more manic/hypomanic features, was present in around one-third of patients experiencing an MDE. The valid symptom, illness

    AIM: To determine predictors of clinical outcome following percutaneous transluminal angioplasty (PTA) in elderly patients with below knee atherosclerotic lesions causing intermittent claudication (IC) or critical limb ischaemia (CLI). MATERIALS AND METHODS: Over 7.5 years, 76 patients (CLI 72%, n = 55) underwent below knee PTA. The composite end-point of interest was major adverse clinical outcome (MACO) of the treated limb at follow-up which was defined as clinical failure, need for subsequent endovascular or surgical revascularization or amputation. Actuarial freedom from MACO was assessed using Kaplan-Meier curves and multivariable Cox proportional hazards regression. RESULTS: IC was improved in 95% at mean 3.4 years (range 0.5-108 months). Successful limb salvage and ulcer healing were seen in 73% with CLI. Most failures were in the CLI group (27% CLI vs. 5% IC), with an amputation rate of 16% for CLI vs. 5% for IC and persistent ulceration in 24% of CLI. Significant independent predictors of MACO were ulceration (hazard ratio 4.02, 95% CI = 1.55-10.38) and family history of atherosclerosis (hazard ratio 2.53, 95% CI = 1.1-5.92). CONCLUSION: Primary below knee PTA is a feasible therapeutic option in this elderly population. Limb ulceration and family history of atherosclerosis may be independent predictors of adverse outcome.

    Full Text Available Objective: To correlate neurotrophic factors – brain-derived neurotrophic factor (BDNF, glial cell line-derived neurotrophic factor (GDNF, and beta-nerve growth factor (beta-NGF – and severity of depressive symptoms in patients diagnosed with major depressive disorder (MDD undergoing cognitive-behavioral therapy (CBT. Methods: In this quasi-experimental study, participants were selected by convenience and received 16 sessions of CBT. The outcomes of interest were severity of depressive symptoms and changes in neurotrophic factor levels after CBT. The differences between variables before and after treatment (deltas were analyzed. Results: Patients had significant changes in symptom severity after treatment. No significant associations were found between Beck Depression Inventory II (BDI-II scores and any independent variable. No correlations were observed between BDNF or GDNF levels and BDI scores before or after treatment, although there was a trend toward significant differences in beta-NGF levels. Conclusion: BDNF, beta-NGF, and GDNF were not influenced by the effects of CBT on depressive symptoms.

    Thyroid disfunction affects negatively emotional stability and worsens the clinical course of bipolar affective disorder. The main stabilizer used in this illness, lithium carbonate has numerous effects on the physiology of the thyroid, with the most significant being the inhibition of thyroid hormone release that may occur at therapeutic levels. These dysfunctions have also been reported most frequently in bipolar patients not undergoing treatment with lithium, and was not completely explained by the effects of this drug. Apart from the numerous medical complications and mood disturbances, the cognitive or perceptual system may also be affected. In fact, the presence of thyroid disease increases the rates of obsessive compulsive disorder, phobias, panic disorder, major depressive disorder, cyclothymia, or bipolar disorder. In severe cases of hypothyroidism, the clinical symptoms and signs can be similar to a melancholic depression or dementia. It is therefore important to know well all these possible complications in daily clinical practice. This review will cover the main thyroid dysfunctions present in bipolar patients, whether ot not produced by treatment with lithium carbonate, and will provide a series of recommendations for clinical management.

    Depression is associated with low serum Brain Derived Neurotrophic Factor (BDNF) and elevated levels of serum cortisol. Yoga practices have been associated with antidepressant effects, increase in serum BDNF, and reduction in serum cortisol. This study examined the association between serum BDNF and cortisol levels in drug-naïve patients with depression treated with antidepressants, yoga therapy, and both. Fifty-four drug-naïve consenting adult outpatients with Major Depression (32 males) received antidepressants only (n = 16), yoga therapy only (n = 19), or yoga with antidepressants (n = 19). Serum BDNF andcortisol levels were obtained before and after 3 months using a sandwich ELISA method. One-way ANOVA, Chi-square test, and Pearson's correlation tests were used for analysis. The groups were comparable at baseline on most parameters. Significant improvement in depression scores and serum BDNF levels, and reduction in serum cortisol in the yoga groups, have been described in previous reports. A significant negative correlation was observed between change in BDNF (pre-post) and cortisol (pre-post) levels in the yoga-only group (r = -0.59, p = 0.008). In conclusion, yoga may facilitate neuroplasticity through stress reduction in depressed patients. Further studies are needed to confirm the findings and delineate the pathways for these effects.

    As one of the problematic behaviors in patients with major depressive disorder (MDD), excessive online game play (EOP) has been reported in a number of recent studies. Bupropion has been evaluated as a potential treatment for MDD and substance dependence. We hypothesized that bupropion treatment would reduce the severity of EOP as well as depressive symptoms. Fifty male subjects with comorbid EOP and MDD were randomly assigned to bupropion + education for internet use (EDU) or placebo + EDU groups. The current study consisted in a 12-week, prospective, randomized, double-blind clinical trial, including an eight-week active treatment phase and a four-week post treatment follow-up period. During the active treatment period, Young Internet Addiction Scale (YIAS) scores and the mean time of online game playing in the bupropion group were greatly reduced compared with those of the placebo group. The Beck Depression Inventory (BDI) scores in the bupropion group were also greatly reduced compared with those of the placebo group. During the four-week post-treatment follow-up period, bupropion-associated reductions in online game play persisted, while depressive symptoms recurred. Conclusively, bupropion may improve depressive mood as well as reduce the severity of EOP in patients with comorbid MDD and online game addiction.

The purpose is to study the morphological features of the major duodenal papilla in patients with cholelithiasis. Material and methods. During autopsies, selection of fragments of major duodenal papilla from 30 dead was performed. The main group consisted of autopsy specimens (n = 15 from the dead, which had stones in the gallbladder in the absence of signs of inflammation of the walls of the gallbladder and bile ducts. Biomaterial samples (n = 15 from the dead, which had no stones and signs of inflammation of the biliary system, were included in the control group. To study the severity of the stromal component, the Mason’s trichrome and the Van Gieson’s stains were used. Light microscopy was carried out using a light microscope Axioplan 2 (Carl Zeiss - Germany using x10, x20, x40, x100 lenses and x10 eyepiece. For a quantitative assessment of the severity of sclerotic changes, we conducted a morphometric study of preparations stained with picrofuchsin accordimg to Van Gieson. The area of the stromal component was calculated in the resulted images in 5 fields of view under magnification of x200 using the medical software for analysis and processing of digital images ImageJ, initiated by W.

    Various otolaryngology associations provide Internet-based patient education material (IPEM) to the general public. However, this information may be written above the fourth- to sixth-grade reading level recommended by the American Medical Association (AMA) and National Institutes of Health (NIH). The purpose of this study was to assess the readability of otolaryngology-related IPEMs on various otolaryngology association websites and to determine whether they are above the recommended reading level for patient education materials. Analysis of patient education materials from 9 major otolaryngology association websites. The readability of 262 otolaryngology-related IPEMs was assessed with 8 numerical and 2 graphical readability tools. Averages were evaluated against national recommendations and between each source using analysis of variance (ANOVA) with post hoc Tukey's honestly significant difference (HSD) analysis. Mean readability scores for each otolaryngology association website were compared. Mean website readability scores using Flesch Reading Ease test, Flesch-Kincaid Grade Level, Coleman-Liau Index, SMOG grading, Gunning Fog Index, New Dale-Chall Readability Formula, FORCAST Formula, New Fog Count Test, Raygor Readability Estimate, and the Fry Readability Graph ranged from 20.0 to 57.8, 9.7 to 17.1, 10.7 to 15.9, 11.6 to 18.2, 10.9 to 15.0, 8.6 to 16.0, 10.4 to 12.1, 8.5 to 11.8, 10.5 to 17.0, and 10.0 to 17.0, respectively. ANOVA results indicate a significant difference (P < .05) between the websites for each individual assessment. The IPEMs found on all otolaryngology association websites exceed the recommended fourth- to sixth-grade reading level.

    Depression and pain frequently occur together. The objective of this study was to investigate the effects of depression and pain on the impairment of daily functioning and quality of life (QOL) of depressed patients. We enrolled 131 acutely ill inpatients with major depressive disorder. Depression, pain, and daily functioning were assessed using the 17-item Hamilton Depression Rating Scale, the Short-Form 36 (SF-36) Body Pain Index, and the Work and Social Adjustment Scale. Health-related QOL was assessed using three primary domains of the SF-36: social functioning, vitality, and general health perceptions. Pearson׳s correlation and structural equation modeling were used to examine relationships among the study variables. Five models were proposed. In all, 129 patients completed all the measures. Model 5, both depression and pain impaired daily functioning and QOL, was the most fitted structural equation model (χ(2)=9.2, df=8, p=0.33, GFI=0.98, AGFI=0.94, TLI=0.99, CFI=0.99, RMSEA=0.03). The correlation between pain and depression was weak (r=-0.27, z=-2.95, p=0.003). This was a cross-sectional study with a small sample size. Depression and pain exert a direct influence on the impairment of daily functioning and QOL of depressed patients; this impairment could be expected regardless of increased pain, depression, or both pain and depression. Pain had a somewhat separate entity from depression. Copyright © 2014. Published by Elsevier B.V.

    Major depressive disorder (MDD) is associated with alterations in brain function that might be useful for therapy evaluation. The current study aimed to identify predictors for therapy improvement and to track functional brain changes during therapy. Twenty-one drug-free patients with MDD underwent functional MRI twice during performance of an emotional perception task: once before and once after 4 weeks of antidepressant treatment (mirtazapine or venlafaxine). Twelve healthy controls were investigated once with the same methods. A significant difference between groups was a relative greater activation of the right dorsolateral prefrontal cortex (dlPFC) in the patients vs. controls. Before treatment, patients responding better to pharmacological treatment showed greater activation in the dorsomedial PFC (dmPFC), posterior cingulate cortex (pCC) and superior frontal gyrus (SFG) when viewing of negative emotional pictures was compared with the resting condition. Activations in the caudate nucleus and insula contrasted for emotional compared to neutral stimuli were also associated with successful treatment. Responders had also significantly higher levels of activation, compared to non-responders, in a range of other brain regions. Brain activation related to treatment success might be related to altered self-referential processes and a differential response to external emotional stimuli, suggesting differences in the processing of emotionally salient stimuli between those who are likely to respond to pharmacological treatment and those who will not. The present investigation suggests the pCC, dmPFC, SFG, caudate nucleus and insula may have a key role as a biological marker for treatment response and predictor for therapeutic success.

    Full Text Available We describe a case of Hb D/Beta thalassemia associated with chronic anemia. Hematological analyses performed in a patient with chronic anemia demonstrating microcytosis and hypochromic in his erythrocytes. Specific laboratory diagnosis performed by alkaline and acid electrophoresis, and fetal determination by alkali resistance, indicated it to be Hb D associated with beta thalassemia. Analyses carried out on his family (father, mother and brother confirmed the suspected diagnosis. Hb D/Beta thalassemia is a very rare interaction in the Brazilian population, and its determination required specific laboratorial techniques and hematological analyses.

    The diagnosis of haemoglobinopathies is of growing importance in Norway because of increasing immigration from countries where haemoglobinopathies are prevalent conditions. The aim of this study was to investigate the relationship between mean corpuscular volume (MCV) and the various haemoglobinopathies diagnosed in Norway. For a period of three years, all samples with MCV lower than 70 fl were also examined for beta-thalassaemia and haemoglobin variants HbS, HbC, HbE and HbD. A total of 263 samples with low MCV were analysed by high-pressure liquid chromatography. In 18% of the samples, a variant of haemoglobinopathy was found, mainly beta-thalassemia minor. 119 of the samples were from persons with an ethnic background from a country in which these diseases are common; all observed haemoglobinopathies were found in this group. 35% of persons with low MCV and a mainly African or Asian ethnic origin had a heterozygous haeomglobinopathy. Low MCV in patients with a foreign ethnic origin is a useful first step in the diagnosis of haemoglobinopathies.

    In patients with SCD, the spleen commonly enlarges during the first two decades of life but then undergoes autosplenectomy due to repeated attacks of vaso-occlusion and infarction. This, however, is not the case in Saudi patients with SCD (340 SCD and 23-sickle beta-thalassemia). A total of 363 patients were evaluated. There ages ranged from 1-60 years (mean 60 years). Only 24 (6.6%) of our patients had autosplenectomy. The splenic index increased with age until about 40 years of age and then gradually decreased indicating persistence of splenomegaly in our patients into an older age group. Forty-three patients (11.8%) had marked-massive splenomegaly (splenic index >120cm) and these had higher HbF levels (mean HbF=22.2%) when compared with those who had autosplenectomy (mean HbF=14.6). This is significant (P-value=0.0169) and confirms the effect of HbF on persistence of splenomegaly in SCD patients. Ultrasonography is a simple, safe and accurate method of assessing splenic size in patients with sickle cell disease. Patients with persistent splenomegaly should be followed closely for development of complications which may necessitate splenectomy. (author)

    Blood transfusion is associated with well-known risks. We investigated the difference between a restrictive versus a liberal transfusion strategy on the immune response, as expressed by the production of inflammatory mediators, in patients subjected to major abdominal surgery procedures. Fifty-eight patients undergoing major abdominal surgery were randomized preoperatively to either a restrictive transfusion protocol or a liberal transfusion protocol (with transfusion if hemoglobin dropped be...

    The death of a person is a stressful event. Such stress affects the physical and psychological well-being of the bereaved. As an associated mental disorder, major depressive disorder (MDD) is common. Some dream of the deceased, and these dreams are called bereavement dreams. Some MDD patients also experience dreams. These two types of dreams are sometimes difficult to differentiate. The dream of the bereaved might be only a bereavement-related dream, yet it might be a symptom of MDD. Herein, we report one patient who had distressing dreams after the death of her mother. A 63-year-old woman was referred for psychiatric consultation because of generalized fatigue and insomnia. Questioning her about recent events, she said that her mother had died of colonic carcinoma 5 months previously. Two months after the death, she suddenly started dreaming of her mother, getting angry with her almost every night. Generalized fatigue, insomnia, and distressing dreams appeared simultaneously. The dream caused much distress, making her afraid to fall asleep. Her psychiatric features fulfilled the DSM-IV-TR criteria for MDD, single episode. The death of her mother was considered to be one of the causes of MDD. She was administered 25 mg/day of sertraline hydrochloride. After that, her symptoms gradually disappeared, and the frequency of distressing dreams was reduced. Five months later, physical and psychiatric symptoms of MDD were completely resolved. Subsequently, she has not suffered from any distressing dreams of her mother. This case indicates that dreams experienced after the death of a loved one should not be regarded simply as bereavement dreams. Some of the dreams may be symptoms of MDD. If the dreams are the symptoms of MDD, antidepressant treatment as well as psychotherapy may be useful. Therefore, we should avoid regarding symptoms of MDD as reactions to bereavement.

    The purpose of this study was to investigate the degree of correlation between sexual dysfunction and depression, anxiety, and somatic symptoms among patients with major depressive disorder (MDD) and to identify the dimension most predictive of sexual dysfunction. One-hundred and thirty-five outpatients with MDD were enrolled and were treated with open-label venlafaxine 75 mg daily for one month. The Arizona Sexual Experience Scale-Chinese Version (ASEX-CV), Depression and Somatic Symptoms Scale (DSSS), Hamilton Depression Rating Scale, and Hospital Anxiety and Depression Scale (HADS) were administered at baseline and at one-month follow-up and the improvement percentage (IP) of each scale posttreatment was calculated. Multiple linear regression was used to determine the dimension most predictive of the total ASEX-CV score. Seventy subjects (20 men, 50 women) completed the one-month pharmacotherapy and the four scales. The depression subscale of the HADS was most strongly correlated with the ASEX-CV scale and was the only subscale to independently predict the total ASEX-CV score at the two points. However, the somatic subscale of the DSSS was not correlated with any ASEX-CV item. At the endpoint, depression, anxiety, and somatic symptoms were significantly improved (IP 48.5% to 26.0%); however, very little improvement was observed in the total ASEX-CV score (IP -1.6%). The severity of sexual dysfunction among patients with MDD was most correlated with the severity of the depressive dimension, but not the severity of the somatic dimension. Further studies are indicated to explore the relationships between sexual dysfunction, depression, anxiety, and somatic symptoms.

    Full Text Available Antecedents: Major depressive disorder (MDD is a psychiatric dysfunction that appears with relative frequency in the women with breast cancer diagnosis or which they are in treatment forthe same one. Nevertheless, specific data don’t exist in Colombia about the prevalence of depression in the patients with cancer who suffer from subjected to modified radical mastectomy without reconstruction. Objective: To determine the prevalence of MDD in resident patients in the metropolitan area of Bucaramanga with modified radical mastectomy without reconstruction. Method: It is a descriptive transversal study; it included women older than 18 years. We applied the SCID I. A semi structured interview for MDD based on approaches of the DSM-IV. Results: 80 women were evaluated with ages among the 30-85 years, with a 58.1 year-old average, SD13.79; the prevalence was of 42.5%, (95%CI 31.68 – 53.30 for MDD. The MDD was lower than in those women who had social support in 41.2% (PR 2.41; 95%CI 1.56-3.73 and was higher than in women who had problems due to the surgery in 88.2% (PR 3.41;95%CI 1.35- 8.64, we didn’t find association with age, the grade ofstudy, the marital status, the socioeconomic level, pain scale, the occupation and the time of the surgery. Conclusion: In this study TDM prevalence was higher than similar ones with general population; TDM was related directly with the problems derived from surgery and inversely with the social support.

    Effects of depression treatment are obscured by heterogeneity among patients. Personality types could be one source of heterogeneity that explains variability in treatment response. Clinically meaningful variations in personality patterns could be captured with data-driven subgroups. The aim of this study was to identify such personality types and to explore their predictive value for treatment efficacy. Participants (N = 146) in the current exploratory study came from a randomized controlled trial in primary care depressed patients, conducted between January 1998 and June 2003, comparing different treatments. All participants were diagnosed with a major depressive disorder (MDD) according to the DSM-IV. Primary (care as usual [CAU] or CAU plus a psychoeducational prevention program [PEP]) and specialized (CAU + PEP + psychiatric consultation or cognitive-behavioral therapy) treatment were compared. Personality was assessed with the Neuroticism-Extraversion-Openness Five-Factor Inventory (NEO-FFI). Personality classes were identified with latent profile analysis (LPA). During 1 year, weekly depression ratings were obtained by trimonthly assessment with the Composite International Diagnostic Interview. Mixed models were used to analyze the effects of personality on treatment efficacy. A 2-class LPA solution fit best to the NEO-FFI data: Class 1 (vulnerable, n = 94) was characterized by high neuroticism, low extraversion, and low conscientiousness, and Class 2 (resilient, n = 52) by medium neuroticism and extraversion and higher agreeableness and conscientiousness. Recovery was quicker in the resilient class (class × time: P Personality profile may predict whether specialized clinical efforts have added value, showing potential implications for planning of treatments. © Copyright 2014 Physicians Postgraduate Press, Inc.

    The current study aimed at investigating the latent dimensional structure of sleep quality as indexed by the seven components of the Pittsburgh Sleep Quality Index (PSQI), as well as latent covariance structure between sleep quality, circadian preferences and depressive symptoms. Two hundred twenty-five patients with major depressive disorder (MDD), with an average age of 29.92 ± 10.49 years (aged between 17 and 63), participated in the study. The PSQI, Morningness-Eveningness Questionnaire (MEQ) and Beck Depression Inventory (BDI) were administered to participants. Four sets of latent class analyses were subsequently run to obtain optimal number of latent classes best fit to the data. Mixture models revealed that sleep quality is multifaceted in MDD. The data best fit to four-latent-class model: Poor Habitual Sleep Quality (PHSQ), Poor Subjective Sleep Quality (PSSQ), Intermediate Sleep Quality (ISQ), and Good Sleep Quality (GSQ). MDD patients classified into GSQ latent class (23.6%) reported the lowest depressive symptoms and were more prone to morningness diurnal preferences compared to other three homogenous sub-groups. Finally, the significant association between eveningness diurnal preferences and depressive symptomatology was significantly mediated by poor sleep quality. The cross-sectional nature of the study and the lack of an objective measurement of sleep such as polysomnography recordings was the most striking limitation of the study. We concluded sleep quality in relation to circadian preferences and depressive symptoms has a heterogeneous nature in MDD. Copyright © 2018. Published by Elsevier B.V.

    Major depressive disorder (MDD) is associated with suicide. Although several studies have reported its association with low serum lipid, few studies have investigated relationships between current suicidality and lipid profiles, comparing with other blood measures in MDD patients. The study population consisted of 555 subjects with MDD who were ≥ 18 years old, evaluated by the Mini International Neuropsychiatric Interview (MINI) with the suicidality module. At the evaluation visit, we measured serum lipid profiles including total cholesterol, triglycerides (TG), low-density lipoprotein (LDL), high-density lipoprotein (HDL), and very low-density lipoprotein (VLDL), and blood measures such as fasting glucose, total protein, albumin, blood urea nitrogen, creatinine, thyroid hormones, red and white blood cells, platelet count, hemoglobin, and hematocrit. Recent attempters who had attempted suicide within the past month showed significantly lower TG and higher HDL levels than lifetime and never attempters, using Tukey's post-hoc analysis. Recent attempters exhibited lower TG and higher HDL than those with recent suicide ideation and wish to self-harm and those without previous attempt. Linear regression analysis revealed that TG was negatively associated with current suicidality scores (β = -0.187, p = 0.039), whereas VLDL was positively associated with the recent suicide status (β = 0.198, p = 0.032) after controlling for age and sex. There were no significant differences between the groups in terms of other serum lipid profiles and blood measures. Low serum TG, high HDL and VLDL levels are associated with recent suicide attempt or recent suicide status in patients with MDD. Copyright © 2014 Elsevier Inc. All rights reserved.

    Transcranial direct current stimulation (tDCS) is a promising treatment for major depressive disorder (MDD). Standard tDCS treatment involves numerous sessions running over a few weeks. However, not all participants respond to this type of treatment. This study aims to investigate the feasibility of identifying MDD patients that respond to tDCS treatment based on resting-state electroencephalography (EEG) recorded prior to treatment commencing. We used machine learning to predict improvement in mood and cognition during tDCS treatment from baseline EEG power spectra. Ten participants with a current diagnosis of MDD were included. Power spectral density was assessed in five frequency bands: delta (0.5-4Hz), theta (4-8Hz), alpha (8-12Hz), beta (13-30Hz) and gamma (30-100Hz). Improvements in mood and cognition were assessed using the Montgomery-Åsberg Depression Rating Scale and Symbol Digit Modalities Test, respectively. We trained the classifiers using three algorithms (support vector machine, extreme learning machine and linear discriminant analysis) and a leave-one-out cross-validation approach. Mood labels were accurately predicted in 8 out of 10 participants using EEG channels FC4-AF8 (accuracy=76%, p=0.034). Cognition labels were accurately predicted in 10 out of 10 participants using channels pair CPz-CP2 (accuracy=92%, p=0.004). Due to the limited number of participants (n=10), the presented results mainly aim to serve as a proof of concept. These finding demonstrate the feasibility of using machine learning to identify patients that will respond to tDCS treatment. These promising results warrant a larger study to determine the clinical utility of this approach. Copyright © 2016 Elsevier B.V. All rights reserved.

    Full Text Available Acute sickle hepatic crisis (ASHC has been observed in approximately 10% of patients with sickle cell disease. It occurs predominantly in patients with homozygous (Hb SS sickle cell anemia and to a lesser degree in patients with Hb SC disease, sickle cell trait, and Hb S beta thalassemia. Patients commonly present with jaundice, right upper quadrant pain, nausea, low-grade fever, tender hepatomegaly, and mild to moderate elevations in serum AST, ALT, and bilirubin. We describe the case of a patient with a history of hemoglobin SC disease and cirrhosis caused by hepatitis C presenting approximately 1 year after liver transplantation with an ASHC. The diagnosis was confirmed by liver biopsy. Our patient was treated with RBC exchange transfusions, IV hydration, and analgesia and made a complete recovery. Only a limited number of patients with sickle cell disease have received liver transplants, and, to our knowledge, this is the first case of ASHC after transplantation in a patient with Hb SC disease.

    The extent to which a family history of mood disorders and suicide could impact on clinical features of patients suffering from major depression (MD) and bipolar disorder (BD) has received relatively little attention so far. The aim of the present work is, therefore, to assess the clinical implications of the presence of at least one first- and/or second-degree relative with a history of MD, BD and suicide in a large sample of patients with MD or BD. One thousand one hundred and fifty-seven subjects with MD and 686 subjects with BD were recruited within the context of two large projects. The impact of a family history of MD, BD, and suicide-considered both separately and together-on clinical and socio-demographic variables was investigated. A family history of MD, BD, and suicide was more common in BD patients than in MD patients. A positive family history of mood disorders and/or suicide as well as a positive family history of MD and BD separately considered, but not a positive history of suicide alone, were significantly associated with a comorbidity with several anxiety disorders and inversely associated with age of onset. The clinical implications as well as the limitations of our findings are discussed.

    Robust cost estimates of cardiovascular (CV) events are required for assessing health care interventions aimed at reducing the economic burden of major adverse CV events. This review synthesizes international cost estimates of CV events. MEDLINE database was searched electronically for English language studies published during 2007-2012, with cost estimates for CV events of interest - unstable angina, myocardial infarction, heart failure, stroke, and CV revascularization. Included studies provided at least one estimate of patient-level direct costs in adults for any identified country. Information on study characteristics and cost estimates were collected. All costs were adjusted for inflation to 2013 values. Across the 114 studies included, the average cost was US $6,466 for unstable angina, $11,664 for acute myocardial infarction, $11,686 for acute heart failure, $11,635 for acute ischemic stroke, $37,611 for coronary artery bypass graft, and $13,501 for percutaneous coronary intervention. The ranges for cost estimates varied widely across countries with US cost estimate being at least twice as high as European Union costs for some conditions. Few studies were found on populations outside the US and European Union. This review showed wide variation in the cost of CV events within and across countries, while showcasing the continuing economic burden of CV disease. The variability in costs was primarily attributable to differences in study population, costing methodologies, and reporting differences. Reliable cost estimates for assessing economic value of interventions in CV disease are needed.

    This study was conducted to determine the protective effect of influenza vaccine against primary major adverse cardiovascular events (MACEs) in elderly patients, especially those with influenza-like illness (ILI). This retrospective, population-based case-control study of an elderly population (age≥65 years) was conducted using Taiwan's National Health Insurance Research Database (2000-2013). One control was selected for each MACE case (n=80,363 each), matched according to age, year of study entry, and predisposing factors for MACEs. ILI and MACEs (myocardial infarction [MI] and ischemic stroke) were defined according to the International Classification of Diseases, Ninth Revision, Clinical Modification. Odds ratios (ORs) were calculated for the association between MACEs and vaccination. Influenza vaccination received in the previous year was associated with reduced risks of primary MACEs overall (adjusted OR [aOR] 0.80, 95% CI 0.78-0.82, Prisks of MACEs (aOR 1.24, 95% CI 1.18-1.29, PVaccination attenuated the heightened risks associated with ILI (MACEs: aOR 0.99, 95% CI 0.92-1.07, P=.834; MI: aOR 1.05, 95% CI 0.92-1.21, P=.440; ischemic stroke: aOR 0.96, 95% CI 0.89-1.05, P=.398). Results of this study suggest that influenza vaccination is associated with reduced primary MACE risks in the elderly population, including those with ILI. Copyright © 2017 Elsevier Inc.

    Full Text Available Burn-related injuries are a significant burden in children, particularly in low- and middle-income countries (LMICs, where more than 90% of burn-related pediatric deaths occur. Lack of adult supervision of children is a major risk for pediatric burn injuries. The goal of this paper was to examine the general characteristics of burns and identify burn injury outcomes among adult-supervised children compared to those who were not supervised. The study examined burn injury and clinical characteristics among all burn patients admitted to two trauma hospitals in The Gambia, West Africa. At intake in the emergency room, the treating physician or nurse determined the need for admission based on body surface area burned (BSAB, depth of burn, and other clinical considerations such as co-occurring injuries and co-morbidities. During the study period of 1 April 2014 through 31 October 2016, 105 burn patients were admitted and data were collected by the treating physician for all of them. Information about supervision was only asked for children aged five years or less. More than half (51% of the burn patients were children under 18 years, and 22% were under 5 years. Among children under five, most (86.4% were supervised by an adult at the time of burn event. Of the 19 supervised children, 16 (84.2% had body area surface burned (BSAB of less than 20%. Two of the three children without adult supervision at the time of burn event had BSAB ≥ 20%. Overall, 59% of the patients had 20% + BSAB. Females (aOR = 1.25; 95% CI = 0.43–3.62, those burned in rural towns and villages (aOR = 2.29; 95% CI = 0.69–7.57, or burned by fire or flames (aOR = 1.47; 95% CI = 0.51–4.23 had increased odds of having a BSAB ≥ 20%, although these differences were not statistically significant. Children 0–5 years or 5–18 years (aOR = 0.04, 95% CI = 0.01–0.17; aOR = 0.07, 95% CI = 0.02–0.23, respectively were less likely to have BSAB ≥ 20% than adults. Those burned in a

    Some clinical studies have reported reduced peripheral glial cell line-derived neurotrophic factor (GDNF) level in elderly patients with major depressive disorder (MDD). We verified whether a reduction in plasma GDNF level was associated with MDD. Plasma GDNF level was measured in 23 healthy control subjects and 23 MDD patients before and after 6 weeks of treatment. Plasma GDNF level in MDD patients at baseline did not differ from that in healthy controls. Plasma GDNF in MDD patients did not differ significantly from baseline to the end of treatment. GDNF level was significantly lower in recurrent-episode MDD patients than in first-episode patients before and after treatment. Our findings revealed significantly lower plasma GDNF level in recurrent-episode MDD patients, although plasma GDNF levels in MDD patients and healthy controls did not differ significantly. The discrepancy between our study and previous studies might arise from differences in the recurrence of depression or the ages of the MDD patients.

    Major depressive disorder (MDD) is a widespread psychiatric disorder with incapacitating symptoms. Oxidative stress has been identified to play a role in the pathophysiology of MDD. To evaluate the therapeutic effectiveness of a chemically defined and antioxidant-rich Chlorella vulgaris extract (CVE) as adjunct to standard treatment in patients suffering from MDD. Subjects with MDD diagnosis according to DSM-IV criteria who were receiving standard antidepressant therapy were assigned to add-on therapy with CVE (1800 mg/day; n=42), or continued standard antidepressant therapy alone (n=50) for a period of 6 weeks. Changes in the frequency of depressive symptoms were assessed using the Hospital Anxiety and Depression Scale (HADS) and Beck Depression Inventory II (BDI-II) scale. There were significant reductions in total and subscale BDI-II and HADS scores in both CVE and control groups by the end of trial. The magnitude of reductions in total BDI-II score [-4.14 (-5.30 to -2.97)] as well as physical [-2.34 (-2.84 to -1.84)] and cognitive [-1.12 (-1.62 to -0.61)] subscales were significantly greater in the CVE versus control group, however, reduction of the affective symptoms was greater in the control compared with the CVE group [0.95 (0.18-0.72)]. Total HADS [-3.71 (-4.44 to -2.98)] as well as individual subscales of depression [-1.46 (-2.02 to -0.90)] and anxiety [-2.25 (-2.74 to -1.76)] were reduced to a greater degree in the CVE group. CVE was well tolerated and no serious adverse event was reported. This pilot exploratory trial provides the first clinical evidence on the efficacy and safety of adjunctive therapy with CVE in improving physical and cognitive symptoms of depression as well as anxiety symptoms in patients who are receiving standard antidepressant therapy.

    Anderson-Fabry Disease (AFD) is an X linked lysosomal storage disorder caused by mutations in the α-galactosidase A gene. Some mutations are associated with prominent and, in many cases, exclusive cardiac involvement. The primary aims of this study were to determine the incidence of major cardiac events in AFD and to identify clinical and genetic predictors of adverse outcomes. We studied 207 patients with AFD (47% male, mean age 44 years, mean follow-up 7.1 years). Fifty-eight (28%) individuals carried mutations that have been previously associated with a cardiac predominant phenotype. Twenty-one (10%) developed severe heart failure (New York Heart Association functional class (NYHA) ≥3), 13 (6%) developed atrial fibrillation (AF), 13 (6%) received devices for the treatment of bradycardia; there were a total of 7 (3%) cardiac deaths. The incidence of the primary endpoint (a composite of new onset AF, NYHA ≥ 3 symptoms, device insertion for bradycardia and cardiac death) was 2.64 per 100 person-years (CI 1.78 to 3.77). Age (HR 1.04, CI 1.01 to 1.08, p=0.004), Mainz Severity Score Index score (HR 1.05, CI 1.01 to 1.09, p=0.012) and QRS duration (HR 1.03, CI 1.00 to 1.05, p=0.020) were significant independent predictors of the primary endpoint. The presence of a cardiac genetic variant did not predict the primary end point. AFD is associated with a high burden of cardiac morbidity and mortality. Adverse cardiac outcomes are associated with age, global disease severity and advanced cardiac disease but not the presence of cardiac genetic variants. Published by the BMJ Publishing Group Limited.

This review synthesizes international cost estimates of CV events.Methods: MEDLINE database was searched electronically for English language studies published during 2007-2012, with cost estimates for CV events of interest – unstable angina, myocardial infarction, heart failure, stroke, and CV revascularization. Included studies provided at least one estimate of patient-level direct costs in adults for any identified country. Information on study characteristics and cost estimates were collected. All costs were adjusted for inflation to 2013 values.Results: Across the 114 studies included, the average cost was US $6,466 for unstable angina, $11,664 for acute myocardial infarction, $11,686 for acute heart failure, $11,635 for acute ischemic stroke, $37,611 for coronary artery bypass graft, and $13,501 for percutaneous coronary intervention. The ranges for cost estimates varied widely across countries with US cost estimate being at least twice as high as European Union costs for some conditions. Few studies were found on populations outside the US and European Union.Conclusion: This review showed wide variation in the cost of CV events within and across countries, while showcasing the continuing economic burden of CV disease. The variability in costs was primarily attributable to differences in study population, costing methodologies, and reporting differences. Reliable cost estimates for assessing economic value of interventions in CV disease are needed. Keywords: cardiovascular diseases, health care costs, hospitalization economics, follow-up studies

    Subsyndromal symptomatic depression (SSD) is a subtype of subthreshold depressive and can lead to significant psychosocial functional impairment. Although the pathogenesis of major depressive disorder (MDD) and SSD still remains poorly understood, a set of studies have found that many same genetic factors play important roles in the etiology of these two disorders. Nowadays, the differential gene expression between MDD and SSD is still unknown. In our previous study, we compared the expression profile and made the classification with the leukocytes by using whole-genome cRNA microarrays among drug-free first-episode subjects with SSD, MDD and matched healthy controls (8 subjects in each group), and finally determined 48 gene expression signatures. Based on these findings, we further clarify whether these genes mRNA was different expressed in peripheral blood in patients with SSD, MDD and healthy controls (60 subjects respectively). With the help of the quantitative real-time reverse transcription-polymerase chain reaction (RT-qPCR), we gained gene relative expression levels among the three groups. We found that there are three of the forty eight co-regulated genes had differential expression in peripheral blood among the three groups, which are CD84, STRN, CTNS gene (F = 3.528, p = 0.034; F = 3.382, p = 0.039; F = 3.801, p = 0.026, respectively) while there were no significant differences for other genes. CD84, STRN, CTNS gene may have significant value for performing diagnostic functions and classifying SSD, MDD and healthy controls.

    Previous studies suggest the presence of attentional bias towards suicide-relevant information in suicidal individuals. However, the findings are limited by their reliance on behavioral measures. This study investigates the role of difficulty in disengaging attention from suicide-relevant stimuli using the P300 component of event-related potentials (ERPs). Forty-four adults with Major Depressive Disorder (MDD) were administered the spatial cueing task using suicide-relevant and negatively-valenced words as cue stimuli. Disengagement difficulty was measured using reaction time and P300 during invalid trials. P300 amplitudes at Pz were higher in suicide-relevant compared to negatively-valenced word condition on invalid trials for participants with low rates of suicidal behavior. However, no such difference was found among participants with high rates of suicidal behavior. P300 amplitudes for suicide-relevant word condition were negatively correlated with "lifetime suicide ideation and attempt" at Pz. No significant results were found for the reaction time data, indicating that the ERP may be more sensitive in capturing the attentional disengagement effect. The groups were divided according to Suicidal Behaviors Questionnaire-Revised (SBQ-R) total score. Neutral stimulus was not included as cue stimuli. Most participants were under medication during the experiment. Our results indicate that patients with MDD and low rates of suicidal behavior show difficulty in disengaging attention from suicide-relevant stimuli. We suggest that suicide-specific disengagement difficulties may be related to recentness of suicide attempt and that acquired capability for suicide may contribute to reduced disengagement difficulties.

    Full Text Available Introduction. Whole body CT is being used increasingly in the primary survey of major trauma patients. We evaluated whether omitting plain films of the chest and pelvis in the primary survey was safe. We compared the probability of survival of patients and time to CT who had plain X-rays to those who did not. Method. We performed a database study on major trauma patients admitted between 2008 and 2010 using data from Trauma, Audit and Research Network (TARN and our PACS system. We included adult major trauma patients who has an ISS of greater than 15 and underwent whole body CT. Results. 245 patients were included in the study. 44 (17.9% did not undergo plain films. The median time to whole body CT from the time of admission was longer (47 minutes in patients having plain films, than those who did not have plain films performed (30 minutes, P<0.005. Mortality was increased in the group who received plain films, 9.5% compared to 4.5%, but this was not statistically significant (P=0.77. Conclusion. We conclude that plain films may be safely omitted during the primary survey of selected major trauma patients.

    Previous research on serum total cholesterol and suicidality has yielded conflicting results. Several studies have reported a link between low serum total cholesterol and suicidality, whereas others have failed to replicate these findings, particularly in patients with major affective disorders. These discordant findings may reflect the fact that studies often do not distinguish between patients with bipolar and unipolar depression; moreover, definitions and classification schemes for suicide attempts in the literature vary widely. Subjects were patients with one of the three major psychiatric disorders commonly associated with suicide: schizophrenia, bipolar affective disorder, and major depressive disorder (MDD). We compared serum lipid levels in patients who died by suicide (82 schizophrenia, 23 bipolar affective disorder, and 67 MDD) and non-suicide controls (200 schizophrenia, 49 bipolar affective disorder, and 175 MDD). Serum lipid profiles did not differ between patients who died by suicide and control patients in any diagnostic group. Our results do not support the use of biological indicators such as serum total cholesterol to predict suicide risk among patients with a major psychiatric disorder.

    Objective: To evaluate the clinical outcomes of patients complicated with major bleeding after primary coronary intervention (PCI) for acute ST-segment elevation myocardial infarction (STEMI). Methods: During the period of January 2004-January 2008, primary PCI was performed in 412 consecutive patients with acute STEMI at Shanghai Ruijin Hospital. The clinical data were retrospectively analyzed. Major adverse cardiac events (MACE), including death, reoccurrence of myocardial infarction and target vessel revascularization, in patients with major bleeding were compared with that in patients without major bleeding. Results: Compared to patients without bleeding, the patients with bleeding were older (70.0 ± 8.9 years vs 64.9 ± 12.7 years, P=0.04), mainly the females (51.9% vs 23.1%, P=0.001) and treated more often with glycoprotein (GP) IIb / IIIa receptor inhibitor (88.9% vs 69.4%, P=0.03) or intra-aortic balloon pump (7.4% vs 1.3%, P=0.02). In-hospital and one-year MACE rate in the patients with bleeding was 18.5% and 37.0% respectively,which were significantly higher than that in the patients without bleeding (5.7% and 14.3%, with P=0.008 and P=0.002, respectively). Multivariate analysis indicated that patient aged over 70 years, feminine gender and use of GP IIb/IIIa receptor inhibitor were independent predictors for the occurrence of major bleeding. The occurrence of major bleeding after primary PCI was significantly correlated with MACE occurred within one year after the procedure (OR 2.79, 95% CI: 2.21-5.90, P<0.001). Conclusion: In patients with acute STEMI, the occurrence of major bleeding after primary PCI is closely linked to the increased MACE rate within one year after the treatment.Feminine gender, aged patient and use of GPIIb/IIIa receptor inhibitor are independent predictors to increase the danger of major bleeding.

    Purpose: To assess the correlation between MRI findings of the pancreas with those of the heart and liver in patients with beta thalassemia; to compare the pancreas T2* MRI results with glucose and ferritin levels and labile plasma iron (LPI). Materials and methods: We retrospectively evaluated chronically transfused patients, testing glucose with enzymatic tests, serum ferritin with chemiluminescence, LPI with cellular fluorescence, and T2* MRI to assess iron content in the heart, liver, and pancreas. MRI results were compared with one another and with serum glucose, ferritin, and LPI. Liver iron concentration (LIC) was determined in 11 patients’ liver biopsies by atomic absorption spectrometry. Results: 289 MRI studies were available from 115 patients during the period studied. 9.4% of patients had overt diabetes and an additional 16% of patients had impaired fasting glucose. Both pancreatic and cardiac R2* had predictive power (p 2 = 0.20, p 2 = 0.09, p 2 = 0.14, p 2 = 0.03, p 2 of 0.91. Conclusions: Pancreatic iron overload can be assessed by MRI, but siderosis in other organs did not correlate significantly with pancreatic hemosiderosis.

    There are limited data on the outcome of patients with thalassemia receiving HSCT from non-sibling matched family donors. Of the 341 patients with thalassemia major that underwent donor search at our center from January 2003 to December 2011, 236 (69.2%) had fully matched family donor of which 28 patients (8.2%) had non-sibling matched family donors identified. We report on seven patients with a median age of eight yr (4-21) who underwent myeloablative (n = 4) or RIC (n = 3) HSCT. The median age of the donors was 33 yr (4-47), three were parents, two first cousins, one paternal uncle, and one paternal aunt. All patients achieved primary neutrophil and platelet engraftment at a median of 18 (13-20) and 16 days (11-20), respectively. One patient developed grade II acute GVHD, and two patients developed limited chronic GVHD. One patient experienced secondary GF requiring a second transplant. At a median follow-up of 69 months (7-110), all patients are alive and thalassemia free. Our data emphasize the need for extended family HLA typing for patients with thalassemia major in regions where there is high rate of consanguinity. Transplant from non-sibling matched family donor can result in excellent outcome. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Both major depression and bipolar disorder are associated with an increased risk of developing dementia. However, the differential risk of dementia between major depression and bipolar disorder is rarely investigated. Using the Taiwan National Health Insurance Research Database, a total of 2291 patients aged ≥ 55 years (major depression: 1946 and bipolar disorder: 345) and 2291 age-and sex-matched controls were enrolled between 1998 and 2008, and followed to the end of 2011. Participants who developed dementia during the follow-up were identified. Both patients with bipolar disorder [hazard ratio (HR) 5.58, 95% confidence interval (CI) 4.26-7.32] and those with major depression (HR 3.02, 95% CI 2.46-3.70) had an increased risk of developing dementia in later life, after adjusting for demographic data and medical comorbidities. The sensitivity tests after excluding the 1-year (bipolar disorder: HR 4.73, 95% CI 3.50-6.35; major depression: HR 2.62, 95% CI 2.11-3.25) and 3-year (HR 3.92, 95% CI 2.78-5.54; HR 2.21, 95% CI 1.73-2.83, respectively) follow-up duration also revealed consistent findings. Furthermore, patients with bipolar disorder were associated with an 87% increased risk (HR 1.87, 95% CI 1.48-2.37) of subsequent dementia compared with patients with major depression. Midlife individuals with bipolar disorder or major depression were associated with an elevated risk of developing dementia in later life. Further studies may be required to clarify the underlying mechanisms among major depression, bipolar disorder, and dementia, and to investigate whether prompt intervention may decrease this risk.

    This report shows that the DNA-binding drug, mithramycin, can be efficiently encapsulated in polymeric micelles (PM-MTH), based on Pluronic® block copolymers, by a new microfluidic approach. The effect of different production parameters has been investigated for their effect on PM-MTH characteristics. The compared analysis of PM-MTH produced by microfluidic and conventional bulk mixing procedures revealed that microfluidics provides a useful platform for the production of PM-MTH with improved controllability, reproducibility, smaller size, and polydispersity. Finally, an investigation of the effects of PM-MTH, produced by microfluidic and conventional bulk mixing procedures, on the erythroid differentiation of both human erythroleukemia and human erythroid precursor cells is reported. It is demonstrated that PM-MTH exhibited a slightly lower toxicity and more pronounced differentiative activity when compared to the free drug. In addition, PM-MTH were able to upregulate preferentially γ-globin messenger ribonucleic acid production and to increase fetal hemoglobin (HbF) accumulation, the percentage of HbF-containing cells, and their HbF content without stimulating α-globin gene expression, which is responsible for the clinical symptoms of β-thalassemia. These results represent an important first step toward a potential clinical application, since an increase in HbF could alleviate the symptoms underlying β-thalassemia and sickle cell anemia. In conclusion, this report suggests that PM-MTH produced by microfluidic approach warrants further evaluation as a potential therapeutic protocol for β-thalassemia. PMID:22287841

    Beta (β)-thalassemia is one of the most common monogenic diseases worldwide. Affected pregnancies can be avoided through preimplantation genetic diagnosis (PGD), which commonly involves customized assays to detect the different combinations of β-globin (HBB) gene mutations present in couples, in conjunction with linkage analysis of flanking microsatellite markers. Currently, the limited number of reported closely linked markers hampers their utility in indirect linkage-based PGD for this disorder. To increase the available markers closely flanking the HBB gene, an in silico search was performed to identify all markers within 1 Mb flanking the HBB gene. Fifteen markers with potentially high polymorphism information content (PIC) and heterozygosity values were selected and optimized into a single-tube pentadecaplex PCR panel. Allele frequencies and polymorphism and heterozygosity indices of each marker were assessed in five populations. A total of 238 alleles were observed from the 15 markers. PIC was >0.
