Does Age at Onset of First Major Depressive Episode Indicate the Subtype of Major Depressive Disorder?: The Clinical Research Center for Depression Study

Purpose

The purpose of this study was to evaluate the effects of age at onset of the first major depressive episode on the clinical features of individuals with major depressive disorder (MDD) in a large cohort of Korean depressed patients.

Materials and Methods

We recruited 419 MDD patients of age over 18 years from the Clinical Research Center for Depression study in South Korea. At the start of the study, the onset age of the first major depressive episode was self-reported by the subjects. The subjects were divided into four age-at-onset subgroups: childhood and adolescent onset (ages <18), early adult onset (ages 18-44), middle adult onset (ages 45-59), and late onset (ages 60+). Using analysis of covariance (ANCOVA) and ordinal logistic regression analysis with adjusting the effect of age, the relationships between clinical features and age at onset of MDD were evaluated.

Results

There was an apparent, but inconsistent correlation between clinical features and age at onset. Earlier onset MDD was significantly associated with higher proportion of female gender [adjusted odds ratio (AOR)=0.570, p=0.022], more previous suicide attempts (AOR=0.635, p=0.038), greater number of previous depressive episodes (F=3.475, p=0.016) and higher scores on the brief psychiatric rating scale (F=3.254, p=0.022), its negative symptom subscale (F=6.082, p<0.0001), and the alcohol use disorder identification test (F=7.061, p<0.0001).

Conclusion

Early age at onset may increase the likelihood of distinguishable MDD subtype, and age at onset of the first major depressive episode is a promising clinical indicator for the clinical presentation, course, and outcome of MDD.     

Children at risk of medicinal and non-medicinal poisoning: a population-based case-control study in general practice

Background

Preschool children have a high risk of poisoning. While medicines prescribed by primary care are potential poisoning agents, the risk factors for poisoning from medication are not well described.

Aim

To identify risk factors for medicinal and non-medicinal poisoning in preschool children.

Design and setting

Population-based nested case-control study using The Health Improvement Network primary care database 1988–2004.

Method

Conditional logistic regression was used to identify child, maternal, and social risk factors for medicinal (1316 cases) and non-medicinal poisoning (503 cases), using 17 709 controls matched on general practice.

Results

Poisoning by medicines was independently associated with deprivation (test for trend P<0.001), maternal age (P<0.001), birth order (P<0.001), maternal alcohol misuse (odds ratio [OR] = 5.44, 95% confidence interval [CI] = 1.99 to 14.91), and perinatal depression (OR = 1.54, 95% CI = 1.26 to 1.88). Living in a household with two or more adults lowered the odds of injury compared to single-parent households (OR = 0.85, 95% CI = 0.74 to 0.96) and the odds varied by age, being highest in 2 year olds (OR = 9.61, 95% CI = 7.73 to 11.95). Non-medicinal poisoning was associated with deprivation (P = 0.001), maternal age (P<0.001), and birth order (P<0.001). The odds were raised in 1 year olds (OR = 5.44, 95% CI = 4.07 to 7.26) and 2 year olds (OR = 5.07, 95% CI = 3.73 to 6.90) compared to those aged <1 year.

Conclusion

Primary care data can be used to target interventions to children at risk of poisoning. This is pertinent when prescribing for children/family members, as prescribed medications may become poisoning agents. Prompt identification of maternal depression and alcohol misuse, and delivery of poisoning-prevention interventions at this stage may help prevent poisonings.     

Agreements between indirect calorimetry and prediction equations of resting energy expenditure in end-stage renal disease patients on continuous ambulatory peritoneal dialysis

Purpose

Equations are frequently used to estimate resting energy expenditure (REE) in a clinical setting. However, few studies have examined their accuracy in end-stage renal disease (ESRD) patients.

Materials and Methods

To investigate agreement between indirect calorimetry and several REE estimating equations in 38 ESRD patients on peritoneal dialysis, we performed indirect calorimetry and compared the results with REEs estimated using 5 equations [Harris-Benedict (HBE), Mifflin, WHO, Schofield, and Cunningham].

Results

Measured REE was 1393.2 ± 238.7 kcal/day. There were no significant differences between measured and estimated REEs except Mifflin (1264.9 ± 224.8 kcal/day). Root mean square errors were smallest for HBE, followed by Schofield, Cunningham, and WHO, and largest for Mifflin (171.3, 171.9, 174.6, 175.3, and 224.6, respectively). In Bland-Altman plot, correlation coefficients between mean values and differences were significant for HBE (r = 0.412, p = 0.012) and tended to be significant for Cunningham (r = 0.283, p = 0.086). In DM patients and patients with overhydration, HBE showed significant underestimation when REE increased.

Conclusion

In ESRD patients on continuous ambulatory peritoneal dialysis (CAPD), REE-estimating equations have no significant differences from indirect calorimetry, except Mifflin. However, HBE showed greater bias than others when REE was high.     

CtBP2 overexpression is associated with tumorigenesis and poor clinical outcome of prostate cancer

Introduction

The aim of the study was to evaluate the expression of CtBP2 in prostate cancer and to determine its relationship with clinicopathologic parameters.

Material and methods

The expression of CtBP2 in 119 prostate cancer tissues and 41 normal tissues was examined by qPCR and Western blot analysis, and the results were correlated with clinicopathologic parameters.

Results

CtBP2 expression in prostate cancer tissues was higher than that in normal samples. CtBP2 overexpression was closely correlated with serum prostatic specific antigen (PSA) (p = 0.018), advanced tumor stage (T3) (p = 0.025), higher Gleason scores (p = 0.019), positive extraprostatic extension (p = 0.012), positive vascular invasion (p = 0.011) and perineural invasion (p = 0.035). However, no significant association was found between CtBP2 abnormal expression and other parameters, including age (p = 0.776), positive lymph node (p = 0.872) and positive surgical margin (p = 0.37). Moreover, CtBP2 overexpression was significantly associated with poor clinical outcome of prostate cancer (p = 0.0168).

Conclusions

CtBP2 is overexpressed in prostate cancer, and its increased expression is closely associated with tumor progression and the outcome of prostate cancer.     

Pattern and outcome of acute poisoning cases in a tertiary care hospital in Karnataka, India

Background and Objective:

Acute poisoning is a medical emergency. It is important to know the nature, severity and outcome of acute poisoning cases in order to take up appropriate planning, prevention and management techniques. This study aimed to assess the pattern and outcome of acute poisoning cases in a tertiary care hospital in Karnataka.

Materials and Methods:

This is a retrospective hospital record-based study conducted in a tertiary care hospital attached to a medical institution in Karnataka. The study included 136 cases and data regarding age, sex, time elapsed after intake; circumstances of poisoning, name of the poisonous substance, chemical type, duration of hospitalization, severity and outcome were collected in the prestructured proforma.

Results:

Incidence was more common among males (75.4%) compared to females (24.3). Most cases of acute poisoning presented among 20- to 29-year age group (31.2%) followed by 12- to 19-year age group (30.2%). A majority of poisoning cases (36.0%) were due to organophosphorus compound (OPC). Total mortality was found to be 15.4%. Mortality rate due to corrosives was significantly high compared with OPC poisoning (χ² = 4.12, P = 0.04). Of the 56 patients of OPC and carbamate poisoning, 13 patients (23.2%) had respiratory arrest and required respiratory support. Time lapse had a significant role on the mortality in cases of acute poisoning (χ² = 10.9, P = 0.01).

Conclusion:

Poisoning is more common in young males. The overall mortality is substantially high, mainly contributed by self-poisoning with insecticides and corrosives. Early care in a tertiary care center may help to reduce mortality in India.     

Evaluation of the quality of life and risk of suicide

OBJECTIVE:

To identify the socio-demographic profiles, suicidal ideation, the presence of mental disorders and the quality of life of patients using mental health services in Arapiraca, Alagoas, Brazil.

METHOD:

Interviews were conducted in family health units and the Psychosocial Attention Center. The sample included 202 mental disorder patients with a risk of suicide attempts, 207 mental disorder patients without a risk of suicide attempts and 196 controls. This study used an identification questionnaire, the abbreviated World Health Organization Quality of Life questionnaire, Beck‘s Suicidal Ideation Scale and the Mini International Neuropsychiatric Interview.

RESULTS:

Patients who had a mental disorder and a risk of suicide attempts tended to be single, had less education and lower family income, were not working and showed lower scores in quality of life domains; 73 of these patients had suicidal ideation in the previous week. Depressive disorders, manic episodes, hypomanic episodes, social phobias, obsessive compulsive disorder, post-traumatic stress disorder, psychotic syndromes and generalized anxiety disorder were more frequent and statistically significant for patients at risk for suicide attempts.

CONCLUSION:

The management of patients with a risk of suicide attempts must focus on individual patients because this risk is directly linked to changes in quality of life and the improvement of these patients'' prognosis.     

Examining the Relationship Between Past Orientation and US Suicide Rates: An Analysis Using Big Data-Driven Google Search Queries

Background

Internet search query data reflect the attitudes of the users, using which we can measure the past orientation to commit suicide. Examinations of past orientation often highlight certain predispositions of attitude, many of which can be suicide risk factors.

Objective

To investigate the relationship between past orientation and suicide rate by examining Google search queries.

Methods

We measured the past orientation using Google search query data by comparing the search volumes of the past year and those of the future year, across the 50 US states and the District of Columbia during the period from 2004 to 2012. We constructed a panel dataset with independent variables as control variables; we then undertook an analysis using multiple ordinary least squares regression and methods that leverage the Akaike information criterion and the Bayesian information criterion.

Results

It was found that past orientation had a positive relationship with the suicide rate (P≤.001) and that it improves the goodness-of-fit of the model regarding the suicide rate. Unemployment rate (P≤.001 in Models 3 and 4), Gini coefficient (P≤.001), and population growth rate (P≤.001) had a positive relationship with the suicide rate, whereas the gross state product (P≤.001) showed a negative relationship with the suicide rate.

Conclusions

We empirically identified the positive relationship between the suicide rate and past orientation, which was measured by big data-driven Google search query.     

Factors associated with suicidal behaviour among depressed patients in Penang,Malaysia

Introduction

This study aims to highlight the factors associated with suicidal behavior among patients with depressive disorders.

Material and methods

A retrospective (Jan 2002 – Dec 2007) evaluation of medical records was done at the psychiatric clinic at the Penang (Malaysia) Public Hospital. Data was analyzed using Statistical Package for Social Science SPSS version 13^®. Chi-square (χ²) test was used to assess the association among variables. Odds ratios were calculated. Multiple logistic regression was applied to identify the predictors for suicidal behavior.

Results

Of 298 patients, 99 patients reported having thoughts of suicide. Overall, female respondents, particularly Chinese, constituted the majority reporting suicidal thoughts (p = 0.01). Cigarette (p < 0.01) and alcohol use (p < 0.01) were found to be associated with suicidal ideation. Among patients with medical comorbidities, diabetics were at a high risk for suicidal thoughts (odds ratio – OR = 1.05, 95% confidence interval – CI 0.45-2.46). In terms of social problems, marital and relationship difficulties were the main risk factors (OR = 2.03, 95% CI: 1.16-3.58). The significant predictors for suicidal behavior were found to be smoking and alcohol use (adjusted R² = 0.39, F change = 75.55, p < 0.01).

Conclusions

Chinese females were found at higher risk of suicidal ideation, as were smokers and alcohol users. The elderly aged 50 and over were also at a higher risk, followed by adolescents and youths aged 15-24 years. Comorbid medical complications and social problems were other factors that may contribute to suicidal ideation among the patients with depressive disorders.     

The prevalence of suicidal ideation and attempts among individuals attending an adult psychiatry out-patient clinic in Gondar, Ethiopia

Background

Suicide is a common problem worldwide and the magnitude is high especially in countries where mental illnesses are prevalent and psychiatric services are poor.

Objective

To determine the prevalence of suicidal ideation and attempts among patients who attended the Psychiatry clinic of Gondar University Hospital.

Methods

A cross sectional study was conducted from March–December 2006 involving a total of 474 patients. Data was collected using a pre tested structured questionnaire containing basic socio-demographic variables, psychiatric diagnosis, suicidal ideation, suicidal attempt, the methods of suicide attempt and ways of survival from the attempted suicide. It was administered by psychiatry nurses working in the clinic. The data was analyzed anonymously using SPSS software.

Results

The commonest mental illness was Major Depressive Disorder (51.3%) followed by Psychosis (38%). Ninety one (19.2 %) patients attempted suicide at least once after the onset of the current mental illness and 307(64.8%) have suicidal ideation. The common method of suicidal attempt was hanging (45.1%) and 69.2% were at home. An association was found between suicidal ideation and attempt (OR=33.7; CI=8.2–138.8, p-value <0.01).

Conclusion

Suicidal ideation was common in psychiatric patients. It was also associated with suicidal attempt.     

Remifentanil patient-controlled analgesia for labor – monitoring of newborn heart rate,blood pressure and oxygen saturation during the first 24 hours after delivery

Introduction

There is no available information about the effects of remifentanil labor analgesia on newborns’ vital signs in the first hours after delivery. The aim of the study was to assess changes in the heart rate, blood pressure and oxygen saturation during the first 24 h of neonatal life after using remifentanil patient-controlled analgesia (PCA) for labor analgesia.

Material and methods

Forty-four full-term neonates, 23 from intravenous PCA remifentanil labor anesthesia 0.2 µg/kg, repeated not more frequently than every 2 min, and 21 born to mothers without any pharmacological forms of analgesia, were studied. Heart rate, oxygen saturation, and systolic (SBP) and diastolic blood pressure (DBP) were monitored using a Nellcor Oxi Max monitor N5500 (Tyco Healthcare), and recorded at 1 h, 6 h, 12 h and 24 h.

Results

No significant differences in heart rate (p = 0.54; p = 0.26; p = 0.60; p = 0.83), oxygen saturation (p = 0.21; p = 0.27; p = 0.61; p = 0.9) and DBP (p = 0.98; p = 0.31; p = 0.83; p = 0.58) between the groups at 1 h, 6 h, 12 h and 24 h. Newborns from the remifentanil group had lower SBP at 1 h of life (59 mm Hg vs. 68.5 mm Hg) but the difference was just on the borderline of statistical significance (p > 0.06). There were no significant differences in SBP between the groups at 6 h (p = 0.65), 12 h (p = 0.11), and 24 h (p = 0.89) of life.

Conclusions

Remifentanil PCA analgesia during labor does not significantly modify the oxygen saturation, heart rate and blood pressure in infants during the first day of their life. Therefore, further studies are needed to explain the observed trend for arterial hypotension in the first hour of life in infants born to mothers treated with remifentanil.     

Serum p-cresyl sulfate predicts cardiovascular disease and mortality in elderly hemodialysis patients

Introduction

Previous studies have shown that serum p-cresyl sulfate (PCS) and indoxyl sulfate (IS) were significantly related to clinical outcomes in patients on hemodialysis (HD). However, evidence for the relationship in elderly HD patients remains scarce. We explore whether the two toxins can predict clinical outcomes in elderly HD patients.

Material and methods

Fifty stable HD patients more than 65 years old were enrolled from a single medical center. Serum total and free PCS, IS levels and biochemistry were measured concurrently. The clinical outcomes including cardiovascular events and all-cause mortality were analyzed after 38-month follow-up.

Results

Univariate Cox proportional hazard ratio analysis revealed that cardiovascular events were associated with gender (p = 0.02), diabetes (p < 0.01), calcium (p = 0.01), total PCS (p < 0.01), free PCS (p < 0.01) and total IS (p = 0.05). Multivariate analysis showed that diabetes (p = 0.01), total PCS (p = 0.01) and free PCS (p = 0.04) were related to cardiovascular events. For all-cause mortality, only total PCS (p = 0.01) reached significance after adjusting other confounding factors. However, Kaplan-Meier analysis indicated that free PCS (p = 0.02) and total PCS (p < 0.01) were significantly associated with cardiovascular events and total PCS (p = 0.048) was related to all-cause mortality during 38-month follow-up.

Conclusions

Our results indicate that total PCS is a valuable marker in predicting cardiovascular event and all-cause mortality in elderly HD patients.     

Oxidative stress determined through the levels of antioxidant enzymes and the effect of N-acetylcysteine in aluminum phosphide poisoning

Introduction:

The primary objective of this study was to determine the serum level of antioxidant enzymes and to correlate them with outcome in patients of aluminum phosphide (ALP) poisoning and, secondly, to evaluate the effect of N-acetylcysteine (NAC) given along with supportive treatment of ALP poisoning.

Design:

We conducted a cohort study in patients of ALP poisoning hospitalized at a tertiary care center of North India. The treatment group and control group were enrolled during the study period of 1 year from May 2011 to April 2012.

Interventions:

Oxidative stress was evaluated in each subject by estimating the serum levels of the enzymes, viz. catalase, superoxide dismutase (SOD) and glutathione reductase (GR). The treatment group comprised of patients who were given NAC in addition to supportive treatment (magnesium sulfate and vasopressors, if required), while in the control group, only supportive treatment was instituted. The primary endpoint of the study was the survival of the patients.

Measurements and Results:

The baseline catalase (P = 0.008) and SOD (P < 0.01) levels were higher among survivors than non-survivors. Of the total patients in the study, 31 (67.4%) expired and 15 (32.6%) survived. Among those who expired, the mean duration of survival was 2.92 ± 0.40 days in the test group and 1.82 ± 0.33 days in the control group (P = 0.043).

Conclusions:

This study suggests that the baseline level of catalase and SOD have reduced in ALP poisoning, but baseline GR level has not suppressed but is rather increasing with due time, and more so in the treatment group. NAC along with supportive treatment may have improved survival in ALP poisoning.     

Preoperative Radiologic and Postoperative Pathologic Risk Factors for Early Intra-Hepatic Recurrence in Hepatocellular Carcinoma Patients Who Underwent Curative Resection

Purpose

The risk of hepatocellular carcinoma (HCC) recurrence must be considered ahead of surgery. This study was undertaken to identify pre-operative risk factors for early intrahepatic recurrence of HCC after curative resection in a large-scale.

Materials and Methods

We retrospectively reviewed the preoperative three-phase multi-detector CT (MDCT) and laboratory data for 240 HCC patients who underwent curative resection; tumor size, number, gross shape, capsule integrity, distinctiveness of tumor margin, portal vein thrombosis (PVT), alpha-fetoprotein level (AFP), and protein induced by vitamin K absence-II (PIVKA-II) levels were assessed. Surgical pathology was reviewed; tumor differentiation, capsule, necrosis, and micro-vessel invasion were recorded.

Results

HCC recurred in 61 patients within six months (early recurrence group), but not in 179 patients (control group). In univariate analysis, large tumor size (p = 0.018), shape (p = 0.028), poor capsule integrity (p = 0.046), elevated AFP (p = 0.015), and PIVKA-II (p = 0.008) were significant preoperative risk factors. Among the pathologic features, PVT (p = 0.023), Glisson''s capsule penetration (p = 0.033), microvascular invasion (p < 0.001), and poor differentiation (p = 0.001) showed statistical significance. In multivariate analysis, only the histopathologic parameters of microvascular invasion and poor differentiation achieved statistical significance.

Conclusion

Preoperative CT and laboratory parameters showed limited value, while the presence of microscopic vascular tumor invasion and poorly differentiated HCC correlated with higher risk of early recurrence after curative resection.     

Biomarker to distinguish hepatocellular carcinoma from cholangiocarcinoma by serum a disintegrin and metalloprotease 12

Introduction

The “a distintegrin and metalloprotease” (ADAM) family contributes to regulation of the cell-cell and cell-matrix interaction that are critical determinants of malignancy. It also plays important roles in the degradation of the basement membrane during tumor invasion. To evaluate a distinguishing biomarker for hepatocellular carcinoma from cholangiocarcinoma, a disintegrin and metalloprotease 12 (ADAM12) level was determined.

Material and methods

The indirect ELISA and Western blot analysis for quantification of ADAM12 level in serum was developed. The subjects were 218 histologically confirmed cases, 128 with intrahepatic cholangiocarcinoma, 30 with hepatocellular carcinoma and 60 healthy people.

Results

The ability of test was verified using an analysis of Receiver Operating Characteristic (ROC) curve. The mean value of serum ADAM 12 in hepatocellular carcinoma was significantly higher than cholangiocarcinoma and healthy people (p = 0.001). The AUC for control vs. HCC was 0.826 while for controls vs. CC was 0.679. The results showed that a disintegrin and metalloprotease 12 for hepatocellular carcinoma had better specificity (77.4%) than for cholangiocarcinoma (64.5%). The serum a disintegrin and metalloprotease 12 level was also found to inversely correlate with overall survival (p = 0.02).

Conclusions

A disintegrin and metalloprotease 12 would be most useful as an adjunct biomarker for distinguishing hepatocellular carcinoma from cholangiocarcinoma.     

Myocardial performance index after surgical correction of ventricular septal defects

Introduction

The myocardial performance index (MPI) has been described as a non-invasive Doppler measurement of ventricular function. The aim of this study was to assess MPI following surgical correction of ventricular septal defect (VSD) and to evaluate its impact on postoperative recovery.

Material and methods

This is a prospective study involving 30 children (16 girls and 14 boys) operated on for VSD (group I). The control group (group II) consisted of 30 healthy children (age and sex matched).

Results

We found that both the right and left ventricular (RV and LV) MPI correlated significantly with the ejection fraction (EF) (r = –0.49, p = 0.006, r = –0.51, p = 0.004, respectively). The LV EF and the LV FS were negatively correlated, while the left and right ventricular MPI was positively correlated with the: LVEDD (p = 0.000), the VSD size (p = 0.000), and the postoperative course of the patients in terms of the duration of ventilation (p = 0.000), the duration of use of inotropics (p = 0.000) and the duration of staying in the ICU (p = 0.000). By linear regression, the factors that correlated with the postoperative course of VSD surgery were the RV MPI pre-surgery, MPI 2 days after surgery and the ejection fraction (p = 0.000).

Conclusions

Myocardial performance index is a useful index for measurement of the left and right ventricular function. It correlates significantly with the ejection fraction, fractional shortening, VSD size, and the left ventricular size. It also significantly predicts the outcome of VSD surgery.     

Hemodynamic findings in patients with brain stroke

Introduction

Standard procedures carried out at a stroke department in patients after a cerebral event may prove insufficient for monitoring hemodynamic indices. Impedance cardiography enables hemodynamic changes to be monitored non-invasively. The aim of the work was to describe hemodynamic parameters in patients with acute phase of ischemic and hemorrhagic stroke and to analyse the correlation between the type of hemodynamic response and long-term prognosis.

Material and methods

The 45 consecutive subjects with ischemic stroke and 16 with a hemorrhagic stroke were examined additionally with impedance cardiography during the first day of hospitalization. The heart contractility, pump performance, afterload and preload indices were recorded and calculated automatically and the data analyzed in terms of 6-month mortality.

Results

We found a significant association between the systemic vascular resistance index, Heather index, stroke index, heart rate, systolic and diastolic and mean arterial blood pressure and mortality in patients with ischemic stroke (p = 0.002, p = 0.008, p = 0.012, p = 0.005, p = 0.007, p = 0.009, p = 0.002 respectively). Logistic regression analysis identified the thoracic fluid content as the most significant variable correlating with the non-survival of the patients with ischemic stroke and in the whole group (ischemic and hemorrhagic stroke). The significant parameters were also mean arterial pressure and stroke index in ischemic stroke (the correct answer ratio was 86.67%) and heart rate in the whole group (the correct answer ratio was 80.33%). There were no significant associations in hemorrhagic stroke.

Conclusions

The hemodynamic parameters correlate with long term prognosis in patients with ischemic brain stroke.     

Dyslipidaemia in hypertensive obese type 2 diabetic patients in Jamaica

Introduction

Hypertension and obesity are common problems among diabetic patients accelerating progression of vascular diabetic complications.

Materials and methods

A two-stage stratified random sampling design was used, and individuals aged 15 years and over were interviewed. This cross-sectional study evaluated lipid abnormalities of 117 obese type 2 diabetic patients (28 males and 89 females), and 56 hypertensive obese type 2 diabetic patients (22 males and 34 females). Total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), very-low-density lipoprotein cholesterol (VLDL-C) and high-density lipoprotein cholesterol (HDL-C) concentrations were assayed using standard biochemical methods.

Results

Hypertensive obese type 2 diabetic females had significantly higher mean serum concentrations of TC (p = 0.043), TG (p = 0.046), LDL-C (p= 0.040), TC/HDL-C ratio (p = 0.001) and LDL-C/HDL-C ratio (p = 0.003) compared with hypertensive obese non-diabetic females. Similar results were found in hypertensive obese type 2 diabetic males compared with hypertensive obese non-diabetic males. Hypertensive obese type 2 diabetic females had significantly higher serum TC, TG and TC/HDL-C ratio (p < 0.05) than hypertensive obese type 2 diabetic males. Hypertensive obese type 2 diabetic females had significantly higher mean serum concentrations of TG (p = 0.03) and TC (p = 0.01) than obese type 2 diabetic females. There was a significant association between blood glucose and LDL-C concentrations in type 2 diabetic subjects (r = 0.36; p< 0.05).

Conclusion

Obese hypertensive type 2 diabetic females are exposed more profoundly to risk factors including atherogenic dyslipidaemia compared with males.     

Bone mineral density,bone turnover markers,lean mass,and fat mass in Egyptian children with congenital adrenal hyperplasia

Introduction

Aim of this paper is to assess bone mineral density (BMD) and body composition, by dual energy X-ray absorptiometry (DXA), and various markers of bone growth, in a group of children with congenital adrenal hyperplasia (CAH) on long-term glucocorticoid therapy.

Material and methods

A case-control study included thirty patients with CAH with different states of metabolic control. Their mean age was 7.5 ±4.2 years. All patients are subjected to BMD using DXA at the neck of the femur and lumbar spine. A blood sample was taken for assessment of osteocalcin, osteoprotegerin, and procollagen type 1, as markers of bone formation, as well as RANKL and urinary deoxypyridinoline (DPD), as markers of bone resorption.

Results

We found no difference in BMD in patients and control subjects; however, patients showed significantly lower serum osteocalcin (p = 0.008) and osteoprotegerin (p = 0.0001) and significantly higher serum RANKL levels (p = 0.0001). Our results show that patients had significantly lower lean body mass (p = 0.005) and fat/lean ratio (p = 0.008) compared to matched controls. The duration of treatment showed a significant negative correlation with procollagen type 1 (r = –0.49, p = 0.02) and lean mass % (r = –0.43, p = 0.04); however, it showed a significant positive correlation with total fat mass % (r = 0.6, p = 0.0006), and fat/lean ratio (r = 0.43, p = 0.04). Dose of steroid had a significant positive correlation with BMI SDS (r = 0.4, p = 0.02).

Conclusions

Bone mineral density is normal but bone turnover is low in patients with CAH. There is an increase in fat/lean mass in patients with CAH.     

Laparoscopically assisted colorectal surgery provides better short-term clinical and inflammatory outcomes compared to open colorectal surgery

Introduction

Changes in immune function after surgery may influence overall outcome, length of hospital stay, susceptibility to infection and perioperative tumour dissemination in cancer patients. Our aim was to elaborate on postoperative differences in the immune status and the intensity of the systemic inflammatory response between two groups of prospectively enrolled patients with colorectal cancer, namely patients undergoing laparoscopically assisted or open colorectal surgery.

Material and methods

Blood samples from 77 patients were taken before surgery and then 3 h, 24 h and 4 days after surgery. The inflammatory response was determined by leukocyte counts, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and procalcitonin levels (PCT). Immune status was determined by phenotypic analysis of lymphocyte populations and the activation of mononuclear cells. CD64 expression and cytokine expression were also determined.

Results

Patients undergoing laparoscopically assisted surgery had less intraoperative blood loss (p = 0.002), earlier resumption of diet (p = 0.002) and shorter hospital stay (p = 0.02). Numbers of total leukocytes (p = 0.12), CRP (p = 0.002) and PCT (p = 0.23) were remarkably higher 4 days after surgery in patients who underwent an open colorectal procedure. There was an important decrease in monocyte HLA-DR expression 3 h after surgery in patients undergoing laparoscopically assisted surgery (p = 0.03).

Conclusions

Our study suggests that minimally invasive surgery provides better short-term clinical outcomes for patients with resectable colorectal cancer. The acute inflammatory response is less pronounced. Post-surgical immunological disturbance in both groups is similar, but we observed a divergent effect of different surgical approaches on the expression of HLA-DR on monocytes. However, our results corroborate the results of previous studies.     

Perfusion assessed by real-time contrast echocardiography correlates with clinical and echocardiographic parameters in patients with first STEMI treated with PCI – 6-month follow-up

Introduction

Angiographic flow in an epicardial artery does not define perfusion at a microvascular level in patients with acute myocardial infarction (AMI). The aim of the study was assessing microvascular reperfusion by myocardial contrast echocardiography (MCE) and left ventricular (LV) functional recovery by echocardiographic methods in patients treated with primary PTCA.

Material and methods

100 consecutive patients with first ST-elevation AMI with single vessel disease treated successfully with primary PCI were enrolled. Regional contrast score index (RCSI), ejection fraction (EF), wall motion score index (WMSI), and end-systolic and end-diastolic volume (ESV, EDV) were evaluated during hospitalization and at 6-month follow-up. The patients were divided into 2 groups according to the absence (Group 1) or presence (Group 2) of perfusion defects on MCE.

Results

Group 1 had lower WMSI (p = 0.0009), higher EF than Group 2 (44.7 and 55.9% respectively, p = 0.000067), and lower ESV (66.0 and 52.6 ml respectively, p = 0.003185). In Group 1 LVEF increased significantly on 6-month follow-up (p = 0.026), while in Group 2 it decreased (p = 0.0175). Both EDV and ESV were significantly lower in Group 1 (p = 0.0106 and p = 0.002882, respectively). There was a correlation between the presence of perfusion defects in the initial contrast echo and unfavourable change in ejection fraction during the follow-up (ANOVA for repeated measures, F[1.91] = 5.85, p = 0.0175). The combined clinical end-point (death and reinfarction) was significantly lower in patients without perfusion defect (p = 0.039).

Conclusions

Myocardial contrast echocardiography results correlated with clinical outcome and recovery of systolic left ventricular function at 6-month follow-up.
