    Freezing point depressions (FPD) in phase change solvents containing 2-(diethylamino)ethanol (DEEA) and 3-(methylamino)propylamine (MAPA) were measured using a modified Beckmann apparatus. The measurements were performed for the binary aqueous DEEA and MAPA solutions, respectively......, in the concentration ranges of (0 to 55) mass percent and (0 to 32.5) mass percent of amine. For the ternary aqueous DEEA–MAPA solutions, freezing points were measured for 5:1, 3:1, 1:1, 1:3, and 1:5 molar ratios of DEEA/MAPA. The FPD method was extended for easy and accurate measurement of freezing points in the CO2......, 20, and 27) mass percent MAPA solutions at different CO2 loadings. The apparatus and the experimental method used showed good repeatability and accuracy. The measured freezing point data were compared with monoethanolamine (MEA) and methyl diethanolamine (MDEA) found in the literature...

    For survival in adverse environments where there is drought, high salt concentration or low temperature, some plants seem to be able to synthesize biochemical compounds, including proteins, in response to changes in water activity or osmotic pressure. Measurement of the water activity or osmotic pressure of simple aqueous solutions has been based on freezing point depression or vapor pressure deficit. Measurement of the osmotic pressure of plants under water stress has been mainly based on vapor pressure deficit. However, differences have been noted for osmotic pressure values of aqueous polyethylene glycol (PEG) solutions measured by freezing point depression and vapor pressure deficit. For this paper, the physicochemical basis of freezing point depression and vapor pressure deficit were first examined theoretically and then, the osmotic pressure of aqueous ethylene glycol and of PEG solutions were measured by both freezing point depression and vapor pressure deficit in comparison with other aqueous solutions such as NaCl, KCl, CaCl(2), glucose, sucrose, raffinose, and bovine serum albumin (BSA) solutions. The results showed that: (1) freezing point depression and vapor pressure deficit share theoretically the same physicochemical basis; (2) theoretically, they are proportional to the molal concentration of the aqueous solutions to be measured; (3) in practice, the osmotic pressure levels of aqueous NaCl, KCl, CaCl(2), glucose, sucrose, and raffinose solutions increase in proportion to their molal concentrations and there is little inconsistency between those measured by freezing point depression and vapor pressure deficit; (4) the osmotic pressure levels of aqueous ethylene glycol and PEG solutions measured by freezing point depression differed from the values measured by vapor pressure deficit; (5) the osmotic pressure of aqueous BSA solution measured by freezing point depression differed slightly from that measured by vapor pressure deficit.

    Crystallisation of liquid solutions is of uttermost importance in a wide variety of processes in materials, atmospheric and food science. Depending on the type and concentration of solutes the freezing point shifts, thus allowing control on the thermodynamics of complex fluids. Here we investigate the basic principles of solute-induced freezing point depression by computing the melting temperature of a Lennard-Jones fluid with low concentrations of solutes, by means of equilibrium molecular dynamics simulations. The effect of solvophilic and weakly solvophobic solutes at low concentrations is analysed, scanning systematically the size and the concentration. We identify the range of parameters that produce deviations from the linear dependence of the freezing point on the molal concentration of solutes, expected for ideal solutions. Our simulations allow us also to link the shifts in coexistence temperature to the microscopic structure of the solutions.

    Freezing point depression of selected food solutions were measured at various concentrations in order to reveal the characteristics of solid-liquid phase equilibrium. The measurement were carried out on a hand made apparatus that was calibrated before the measurement by some of selected reagents (acid and sugar) with known thermal properties. The results revealed that the freezing point depression of selected food solutions deviated from the behavior of the ideal solution with increasing solute concentration, so the water activity for non-ideal solution were introduced to the freezing point depression equation. Further, assuming that the heat of fusion was a equation of temperature, thus the following new equation was led, ln {(1-Xs)/(l-Xs+α·Xs + β·Xs2)} = A(1/To - 1/Tf) - Bln(To/Tf) The goodness of fit of the equation showed the best results. Futhermore, by using the parameters a formula of freezing ratio and the relative water activities, which showed deviation from the ideal solution, were derived.

  6. Free Energy Perturbation Monte Carlo Simulations of Salt Influences on Aqueous Freezing Point Depression

    Science.gov (United States)

    Dick, Thomas J.; Wierzbicki, Andrzej; Madura, Jeffry D.

    Free energy perturbation Monte Carlo (FEP/MC) simulations are performed for both the liquid and solid phases of water to determine the melting temperature of several popular three and four-site water models. Gibbs free energy vs. temperature plots are constructed from the simulations to determine the melting temperature. For the liquid phase, standard FEP/MC simulations are used to calculate the free energy relative to the gas phase at multiple temperatures. The free energy of the solid phase relative to the gas phase is calculated at multiple temperatures using the lattice-coupling method. The intersection of the free energy regression lines determines the estimate of the melting temperature. Additionally, simulations were carried out for simple salt solutions to determine the freezing point depressions (FPD). The simulations reproduce the FPD as a function of salt concentration for solutions of NaCl, KCl, CaCl2, and MgCl2.

    2012-01-01

    Aircraft and pavement deicing formulations and other potential freezing point depressants were tested for biochemical oxygen demand (BOD) and chemical oxygen demand (COD). Propylene glycol-based aircraft deicers exhibited greater BOD5 than ethylene glycol-based aircraft deicers, and ethylene glycol-based products had lower degradation rates than propylene glycol-based products. Sodium formate pavement deicers had lower COD than acetate-based pavement deicers. The BOD and COD results for acetate-based pavement deicers (PDMs) were consistently lower than those for aircraft deicers, but degradation rates were greater in the acetate-based PDM than in aircraft deicers. In a 40-day testing of aircraft and pavement deicers, BOD results at 20°C (standard) were consistently greater than the results from 5°C (low) tests. The degree of difference between standard and low temperature BOD results varied among tested products. Freshwater BOD test results were not substantially different from marine water tests at 20°C, but glycols degraded slower in marine water than in fresh water for low temperature tests. Acetate-based products had greater percentage degradation than glycols at both temperatures. An additive component of the sodium formate pavement deicer exhibited toxicity to the microorganisms, so BOD testing did not work properly for this formulation. BOD testing of alternative freezing point depressants worked well for some, there was little response for some, and for others there was a lag in response while microorganisms acclimated to the freezing point depressant as a food source. Where the traditional BOD5 test performed adequately, values ranged from 251 to 1,580 g/kg. Where the modified test performed adequately, values of BOD28 ranged from 242 to 1,540 g/kg.

    1982-01-01

    Methods for identification of the more promising concepts for the development of a portable instrument to rapidly determine the freezing point of aviation fuels are described. The evaluation process consisted of: (1) collection of information on techniques previously used for the determination of the freezing point, (2) screening and selection of these techniques for further evaluation of their suitability in a portable unit for rapid measurement, and (3) an extensive experimental evaluation of the selected techniques and a final selection of the most promising technique. Test apparatuses employing differential thermal analysis and the change in optical transparency during phase change were evaluated and tested. A technique similar to differential thermal analysis using no reference fuel was investigated. In this method, the freezing point was obtained by digitizing the data and locating the point of inflection. Results obtained using this technique compare well with those obtained elsewhere using different techniques. A conceptual design of a portable instrument incorporating this technique is presented.

    Full Text Available Two analytical methods were used for determination of the freezing point on identical test raw milk samples. The aim of this research was to investigate possibility of usage infrared spectrometry method, with MilcoScan FT 6000 milk analyzer for determination of milk freezing point, comparing to results obtained by using a reference thermistor cryoscopy method with Cryoscope 4C3 analyzer. During period of four months, total of 320 milk samples were analyzed. Once a week milk samples were sampled at collection reservoirs from twenty milk producers. Milk freezing point was analyzed with each of investigated methods in three consecutive testing respectively repetition. The results of freezing point were recorded as higher by reference in comparison to infrared spectroscopy method. Mean difference from 1.31 to 5.28 m°C respectively 3.43 m°C was determined between results obtained with infrared spectroscopy and reference method. Mean repeatability results for both investigated methods showed slight difference, sr%=0.194 for the reference method and sr%=0.193 for the infrared spectrometry method. Statistically significant difference between the means of the obtained results with two different investigated methods (P>0.05; P>0,01 was not determined. The results indicate the conclusion that infrared spectroscopy method can be used for detecting adulteration of milk with water addition as screening method. Based upon the obtained results usage of infrared spectrometry method in determination of raw milk freezing point is recommended because it is faster and can be carried out with current analyzers used for determination of other milk quality parameters, for example analyzer MilkoScan FT 6000.

    In order to reduce limitations of solubility, the cryoscopic method developed for benzene solutions of polyphenyl mixtures has been extended to diphenyl-ether solutions by introducing some modifications imposed by the physico-chemical properties of this solvent. The Nernsto theory of Beckman's method has been revised, taking into account the heat-transfer characteristics of the system, and the results of that analysis have been used to fix upon the design parameters of a cryoscopic apparatus for measurements on diphenyl-ether solutions.

    2010-05-25

    Contrary to current widely held beliefs, many concentrated aqueous solutions of electrolytes and nonelectrolytes behave ideally. For both, the same simple equation yields mole fractions of water that are equal to the theoretical activities of water. No empirical activity coefficients or ad hoc parameters are needed. Thermodynamic hydration numbers and the number of particles produced per mole of solute are found by searching freezing-point depression measurements, as if asking the water, "How much available water solvent is left and how many solute particles are there?" The results answer questions currently under debate: Do solutes alter the nature of water outside their immediate surroundings? What is the number of ion pairs formed by various electrolytes and what affects extents of their formation? What are some factors that cause precipitation of proteins, latexes, and so forth from aqueous solutions upon addition of other solutes (Hofmeister series)? Which nonelectrolytes form aggregates in water and what are the implications? Why do different solutes affect viscosity differently? How do ion-selective channels in cell membranes function at the molecular level?

  15. Preliminary report on fluid inclusions from halites in the Castile and lower Salado formations of the Delaware Basin, southeastern New Mexico. [Freezing-point depression

    1985-09-01

    A suite of samples composed primarily of halite from the upper Castile and lower Salado Formations of the Permian Basin was selected from Waste Isolation Pilot Plant (WIPP) core for a reconnaissance study of fluid inclusions. Volume percent of these trapped fluids averaged 0.7% to 1%. Freezing-point depressions varied widely and appeared to be unrelated to fluid-inclusion type, to sedimentary facies, or to stratigraphic depth. However, because very low freezing points were usually associated with anhydrite, a relation may exist between freezing-point data and lithology. Dissolved sulfate values were constant through the Castile, then decreased markedly with lesser depth in the lower Salado. This trend correlates very well with observed mineralogy and is consistent with an interpretation of the occurrence of secondary polyhalite as a result of gypsum or anhydrite alteration with simultaneous consumption of dissolved sulfate from the coexisting fluids. Together with the abundance and distribution of fluid inclusions in primary or ''hopper'' crystal structures, this evidence suggests that inclusions seen in these halites did not migrate any significant geographical distance since their formation. 28 refs., 17 figs., 2 tabs.

    Full Text Available The aim of this study was to evaluate the basic freezing point of buffalo milk. Bulk milk samples were collected from buffalo and cattle farms in Caserta area from 2008 to 2014. The analysis involved a total of 1886 buffalo milk samples and 1711 bovine milk samples. These were also tested for fat, protein and lactose contents by means of infrared spectrometry. The freezing point was determined by means of a thermistor cryoscope. Data underwent statistical analysis. Our research showed an average freezing point of -0.528°C for buffalo milk and - 0.522°C for bovine milk. Given the lack of data on the freezing point of buffalo milk, our study provides the first indication of a basic freezing point of the milk of this species in Italy.

    Full Text Available The study involved determination of the freezing point of cow milk by a reference (thermistor cryoscopy and an instrumental (infrared spectrometry method. The aim of the study was to evaluate the possibility of milk freezing point determination in milk samples preserved with azidiol by using a reference and an instrumental method of analysis. Five hundred cow milk samples were analysed during three research periods. Samples were taken at milk collection points in north-western Croatia. Samples preserved with azidiol (0.3 mL azidiol/40 mL; 0.011 g sodium azide/40 mL and without preservatives (control samples were analysed. The freezing point of milk was determined in duplicate. Average freezing point results of azidiol preserved samples were lower compared to control samples. A statistically significant difference between the means of the results obtained for azidiol preserved and control samples was determined (P<0.05; P<0.01 in all research periods. The results revealed a significant influence of the preservative azidiol on milk freezing point determination regardless of the method of analysis applied, which could lead to wrong interpretation of the results.

    1984-12-01

    This is a report of a rapid and precise screening procedure, developed for the determination of ethanol in serum using osmolality measurements. The osmolality of the patient is determined by freezing point method (freezing point osmometry) and dew point (water vapor pressure osmometry) method. The difference between freezing point osmolality and vapor pressure osmolality (delta osm) is due to the presence of volatiles in the serum, because the volatiles are not measured by vapor pressure osmometry. The amount of ethanol (mg/dL) in serum is estimated by multiplying delta osm by a factor of 4.2. As a comparison method, ethanol also is measured by a spectrophotometric alcohol dehydrogenase method. In addition, a significant difference between an osmometric alcohol assayed value and enzymatic spectrophotometric measurement indicates the presence of volatiles, other than ethanol. In addition to ethanol there is a linear relationship between osmolality and isopropanol or methanol when added in vitro to serum.

  20. Experimental Study of the Freezing Point of γ-Al2O3/Water Nanofluid

    2012-01-01

    Full Text Available Nanofluids are colloidal suspensions made of nanometer-sized particles dispersed in a conventional fluid. Their unusual thermal properties explain intensive investigations for several thermal and industrial applications. In this work, an experimental investigation was performed to measure the freezing point and to study the supercooling point made of alumina γ-Al2O3 nanoparticles with 30 nm diameter size and deionized water. Particles' volume fraction used in this work is ranging from 1% to 4%. The T-historic method based on the measurement of the point of inflexion was performed to measure the thermal properties such as the freezing point and the latent heat of solidification of the nanofluids for different concentrations. The results show that the supercooling degree decreases for the high particles volume concentrations and that the agglomeration does not influence the temperature of the freezing point. However, it makes the freezing process longer.

  2. High-freezing-point fuels used for aviation turbine engines

    Friedman, R.

    1979-01-01

    Broadened-specification aviation fuels could be produced from a greater fraction of crude source material with improvements in fuel supply and price. These fuels, particularly those with increased final boiling temperatures, would have higher freezing temperatures than current aviation turbine fuels. The higher-freezing-point fuels can be substituted in the majority of present commercial flights, since temperature data indicate that in-flight fuel temperatures are relatively mild. For the small but significant fraction of commercial flights where low fuel temperatures make higher freezing-point fuel use unacceptable, adaptations to the fuel or fuel system may be made to accommodate this fuel. Several techniques are discussed. Fuel heating is the most promising concept. One simple system design uses existing heat rejection from the fuel-lubricating oil cooler, another uses an engine-driven generator for electrical heating. Both systems offer advantages that outweigh the obvious penalties.

    Full Text Available Factors affecting the freezing point of milk in a herd of 200 Black and White cows with the average milk yield of 8 386 kg in the lactation and 8 328 kg in the standard lactation were examinated. Over the period of one year (2002 and based upon 1 773 individual monthly collected milk samples with the average contents of 3.91% fat, 3.26% protein, 4.54% lactose, 33.4 mg/100 ml urea and 331000 somatic cells per ml in milk were determined. The average freezing point of milk (n = 1 680 was estimated to be –0.527 ºC, with a range from -0.562 ºC to -0.423 ºC. In 210 (12.5% samples was higher than -0.515 ºC. The lowest freezing point (-0.532 ºC was found in the samples collected in the first month after calving and highest (-0.522 ºC in the samples of 12th month of lactation. The differences between the freezing point of milk after the first and the second calving (-0.530 ºC; P < 0.05 and those after the fifth calving (-0.523 ºC; P < 0.05 were also significant. The samples collected in month from January to April (-0.538 ºC to -0.532 ºC were significantly lower in comparison to samples collected in May and June (-0.517 ºC and -0.519 ºC. The following statistically significant correlation coefficients between cows' properties, milk composition and the freezing point of milk were found: month of lactation r = 0.233 (P < 0.001; lactation number r = 0.196 (P < 0.001; age of cows (years r = 0.231 (P < 0.001; month of the year r = 0.0253 (P < 0.001; milk yield per milking day r = -0.106 (P < 0.001; fat corrected milk content (FCM per milking day r = -0.234 (P < 0.001; lactose % r = -0.530 (P < 0.001; fat % r = -0.351 (P < 0.001; protein % r = 0.058 (P < 0.05; urea mg/100 mL r = 0.091 (P < 0.001 and somatic cell count r = 0.154 (P < 0.001. The sum of effects (month of the year, lactation lenght and fat, protein and lactose content of milk was found to account for about 70% variability of the total depression of milk freezing point (R2 = 0.698.

  7. Freezing point osmometry of milk to determine the additional water content – an issue in general quality control and German food regulation

    Directory of Open Access Journals (Sweden)

    Holz Birger

    2008-03-01

    Full Text Available Abstract Background The determination of the osmolality of aqueous samples using a freezing point osmometer is a well-established, routine laboratory method. In addition to their use in clinical and pharmaceutical laboratories, freezing point osmometers are also employed in food testing laboratories. One application is the determination of the osmolality of milk. Although cow's milk is a natural product whose water content is approximately 87%, the osmolality of milk is a significant value when the milk is collected from a larger population of animals. This value is used in milk processing to control the water content, based on the German Food Control Regulations for Milk. Results Measurement of the freezing point and osmolality of milk samples was performed with a Knauer Semi-Micro Freezing Point Osmometer. Osmolality was measured for the untreated milk samples and following their dilution (by volume with 10% and 50% water. The measurements were made after 1, 4 and 7 days to evaluate changes over time. All measurement values for the undiluted milk were spread over a small interval with an average of 271 mOsmol/kg. After mixing the milk samples with 10% water, the average decreased to 242 mOsmol/kg, while mixing with 50% water resulted in an average osmolality of 129 mOsmol/kg. There was no significant change for the osmolality within the 7 days (measurements from days 1, 4 and 7. Conclusion The results observed demonstrate clearly that the additional water content of milk can be determined easily using a freezing point osmometer. Milk samples that contain additional water have a significantly decreased osmolality, corresponding to an increased freezing point. The effect on osmolality of ageing the milk samples could not be determined in this study's time-dependent measurements.

    Three freezing-point regulators (glycine, sodium chloride and D-sorbitol) were employed to optimize thermophysical properties of Pacific white shrimp (Litopenaeus vannamei) using response surface methodology (RSM). The independent variables were glycine content (0.250-1.250 %), sodium chloride content (0.500-2.500 %) and D-sorbitol content (0.125-0.625 %) and analysis of variance showed that the effects of glycine, sodium chloride and D-sorbitol on the thermophysical properties were statistically significant (P < 0.05). The coefficient of determination, R (2) values for initial freezing point (T i ), unfreezable water mass fraction (W u ), apparent specific heat (C app ) and Enthalpy (H) were 0.896 ~ 0.999. The combined effects of these independent variables on T i , W u , C app and H were investigated. The results indicated that T i , C app and H varied curvilinearly with increasing of glycine, sodium chloride and D-sorbitol content whereas W u increased nearly linearly. Based on response plots and desirability functions, the optimum combination of process variables for Pacific white shrimp previously treated with freezing-point regulators were 0.876 % for glycine content, 2.298 % for sodium chloride content and 0.589 % for D-sorbitol content, correspondently the optimized thermophysical properties were T i , - 5.086 °C; W u , 17.222 %; C app , 41.038 J/g °C and H, 155.942 J/g, respectively. Briefly, the application of freezing-point regulators depressed T i and obtained the optimum W u , C app and H, which would be obviously beneficial for the exploitation of various thermal processing and food storage.

    In this work, the freezing point of tin (Sn FP) was realized by inside nucleation where the supercooling of tin and the reheating of the sample after the nucleation were achieved without extracting the cell from an isothermal apparatus. To this end, a novel hydraulic temperature control technique, which was based on the thermo-hydraulic characteristics of a pressure-controlled loop heat pipe (LHP), was employed to provide a slow cooling of the sample for deep supercooling and fast reheating after nucleation to minimize the amount of initial freeze of the sample. The required temperature controls were achieved by the active pressure control of a control gas inside the compensation chamber of the pressure-controlled LHP, and slow cooling at  -0.05 K min-1 for the deep supercooling of tin and fast heating at 2 K min-1 for reheating the sample after nucleation was attained. Based on this hydraulic temperature control technique, the nucleation of tin was realized at supercooling of around 19 K, and a satisfactorily fast reheating of the sample to the plateau-producing temperature (i.e. 0.5 K below the Sn FP) was achieved without any temperature overshoots of the isothermal region. The inside-nucleated Sn FP showed many desirable features compared to the Sn FP realized by the conventional outside nucleation method. The longer freezing plateaus and the better immersion characteristics of the Sn FP were obtained by inside nucleation, and the measured freezing temperature of the inside-nucleated Sn FP was as much as 0.37 mK higher than the outside-nucleated Sn FP with an expanded uncertainty of 0.19 mK. Details on the experiment are provided and explanations for the observed differences are discussed.

    Soil freezing point is the highest temperature at which ice can be presented in the system and soil can be referred to as frozen. The freezing temperature of soil is an important parameter for solving many practical problems in civil engineering, such as evaluation of soil freezing depth, prediction of soil heaving, force of soil suction, etc. However, as the freezing temperature is always affected by many factors like soil particle size, mineral composition, water content and the external pressure endured by soils, to measure soil freezing point is a rather difficult task until now, not to mention the soil suffering higher pressure. But recently, with the artificial freezing technology widely used in the excavation of deep underground space, the frozen wall thickness is a key factor to impact the security and stability of deep frozen wall. To determine the freeze wall thickness, the location of the freezing front must be determined firstly, which will deal with the determination of the soil freezing temperature. So how to measure the freezing temperature of soil suffering higher pressure is an important problem to be solved. This paper will introduce an equipment which was developed lately by State Key Laboratory of Frozen Soil Engineering to measure the freezing-point of soils under higher pressure. The equipment is consisted of cooling and keeping temperature system, temperature sensor and data collection system. By cooling and keeping temperature system, not only can we make the higher pressure soil sample's temperature drop to a discretionary minus temperature, but also keep it and reduce the heat exchange of soil sample with the outside. The temperature sensor is the key part to our measurement, which is featured by high precision and high sensitivity, what is more important is that the temperature sensor can work in a higher pressure condition. Moreover, the major benefit of this equipment is that the soil specimen's loads can be loaded by any microcomputer

  18. Study on Supercooling Point and Freezing Point in Floral Organs of Apricot

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Under the environment of an artificial climate chamber, supercooling point (SCP) and freezing point (FP) in flower and young fruit at different development stages and freezing injuries of floral organs were studied. The apricot cultivars tested were Kety, Golden Sun and Honghebao. With the development of flower buds, SCP and FP increased, which indicated that their cold resistance decreased. SCP and FP varied with different floral organs. For different apricot cultivars, it was found that, the lower SCP or FP in floral organs was, the more resistant capacity the cultivar had, and the larger the temperature interval from SCP to FP was. SCP was not a constant value, but a range. Frequency distribution of SCP in petals was more dispersing than that in stamens and pistils. Floral organs could maintain a supercooling state to avoid ice formation, but they were sensitive to freezing. Once floral organs froze, they turned brown after thawing.

    Deicers from renewable resources are needed to overcome the disadvantages of using traditional deicers. Salts made from levulinic acid produced using grain sorghum as raw material were tested as road deicing agents. Freezing points of these salts viz., sodium levulinate, magnesium levulinate and calcium levulinate along with rock salt (sodium chloride) were determined according to American Society for Testing and Materials (ASTM) D 1177-94 standard at concentrations of 10, 20, 30 and 40 % w/w. There were significant differences among the freezing points of the salts. Freezing points for rock salt, sodium levulinate, calcium levulinate and magnesium levulinate, for different concentrations, were in the ranges of -6.6 to -20.5, -2.9 to -15.0, -2.1 to -7.8 and -1.5 to -6.5 degrees C, respectively. Deicing effectiveness of the salts of levulinic acid were investigated by conducting small-scale deicing tests with aqueous solutions of various salt concentrations (2%, 5% and 10%) in a laboratory freezer and by spraying the deicer on a graveled surface covered by ice and snow with the average temperature during the testing at -2.7 degrees C. Deicing capabilities of the three salts of levulinic acid differed. At -2.7 degrees C, all three salts caused melting of the ice. Among the different levulinates studied sodium levulinate was the most effective deicing agent. These salts of levulinates could be a viable replacement for traditional deicers and could help in reducing the disadvantages of traditional deicers.

    2016-07-01

    The paper presents the technique of computing flow and heat transfer of water in a pipeline whose initial temperature is lower than the freezing point of water. A feature of the method is the possibility of calculating the process from the moment of pouring water into a pipe on the inner surface of whose wall a layer of ice is being formed. The system of equations describing the process involves nonstationary energy equations for the water flow, ice layer, and for the pipe wall. It is solved for each section of the pipeline passed by water in a small time interval in the process of filling the pipe and further flow. The Beginning computer program has been created and implemented in the Visual Basic language for numerical analysis of the process. The calculations made with the aid of this program allow one to estimate the possibility of appearance of an ice plug in the pipeline at the given temperature, water flow rate, pipeline diameter, and conditions of external heat transfer of water flow in the pipeline.

    Full Text Available Changes in milk quality after the introduction of automatic milking systems (AM-systems on dairy farms in TheNetherlands, Germany and Denmark were examined and the data were compared with milk quality results of farms withconventional milking technology. After introduction, a small, but significant increase in total bacterial count, somatic cellcount, freezing point and free fatty acids was observed. The highest levels for total plate count and cell count are foundin the first six months after introduction. After this period the milk quality slightly improves to a more stable level.Risk factors related with milk quality concern general farm characteristics, animal health, AM-system, cleaning and cooling,housing, management skills of the farmer and the hygiene on the farm. Total plate count was significantly relatedto milk yield of the herd, cleaning of the area around the AM-system and the overall hygiene on the farm. Bulk milksomatic cell count appeared to be significantly related to milk yield of the herd and the number of milkings before replacementof the liners. An increased milking frequency is not the only explanation of increased free fatty acid levels. Technicalfactors related to free fatty acids mainly concerned the air inlet in the teat cups, bubbling (excessive air inlet and a toolong post run time of the milk pump. However, several questions regarding the causes of increased free fatty acid levelsremained unclear.

    Full Text Available Postpartum Depression is the most common complicationof the delivery and affects approximately 10%-15% ofwomen who had just gave birth. During a period in whichwomen believe that they should be happy, the depressivemood experienced by most women leads to feelings ofguilt, hiding the symptoms, and postpartum depressionto be overlooked. Although the incidence of serious psychiatricdisorders during pregnancy is low, it is reportedthat the incidence shows a dramatic increase during thepostpartum period and this risky period may continue upto six months, one year or even two years.As the onset of postpartum depression is insidious it caneasily be overlooked if the patient’s seeking help is notsupported, especially when the severity of postpartum depressionis mild or moderate. In these cases, postpartumdepression may persist for a long time and at last it can beso severe that hospitalization would be needed. Therefore,early diagnose is very important and primary carephysicians and other health care workers should be alert.Postpartum Depression should be diagnosed using reliabledescriptive methods in puerperant women. Thescales such as Postnatal Depression Screening Scale,Beck Depression Inventory, Edinburgh Postnatal DepressionScale and State-Trait Anxiety Inventory, all of whichwere tested for validity and reliability in our country can beused during follow-up of pregnant and puerperal women.Key words: Postpartum depression, screening methods,primary health care professionals

    Depressive disorders are among the more common mental illnesses around the world, about 1- 3% of prepubertal children and 6% of postpubertal children and adolescents are affected. They markedly impair psychosocial development and are associated with higher rate of morbidity and mortality throughout life. Many physicians are unsure about which treatment approaches are effective and how the treatment should be planned. A systematic literature search was carried out in electronic databases and study registries and as a manual search. More than 450 studies (mostly randomized controlled trials = RCTs) were identified and summarized in evidence tables. The ensuing recommendations were agreed upon in a consensus conference. The review summarizes the evidence of complementary treatment methods. The evidence for complementary treatment methods (art and music therapy, sleep deprivation, exercise, electroconvulsive therapy, massage, transcranial magnetic stimulation, relaxation, bibliotherapy, computer based therapy, light therapy, omega-3 treatment) is low or there is no evidence due to missing studies or studies of poor quality. For some methods, i. e. light therapy, relaxation and stress reduction and sleep deprivation there is limited indication for effectiveness without sufficient evidence for a practical guidance. There is an urgent need for adequately informative comparative studies on treatment of depression in children and adolescents considering also complementary methods.

    Seed oils have proved recalcitrant to modification for the production of industrially useful lipids. Here, we demonstrate the successful metabolic engineering and subsequent field production of an oilseed crop with the highest accumulation of unusual oil achieved so far in transgenic plants. Previously, expression of the Euonymus alatus diacylglycerol acetyltransferase (EaDAcT) gene in wild-type Arabidopsis seeds resulted in the accumulation of 45 mol% of unusual 3-acetyl-1,2-diacyl-sn-glycerols (acetyl-TAGs) in the seed oil (Durrett et al., 2010 PNAS 107:9464). Expression of EaDAcT in dgat1 mutants compromised in their ability to synthesize regular triacylglycerols increased acetyl-TAGs to 65 mol%. Camelina and soybean transformed with the EaDAcT gene accumulate acetyl-triacylglycerols (acetyl-TAGs) at up to 70 mol% of seed oil. A similar strategy of coexpression of EaDAcT together with RNAi suppression of DGAT1 increased acetyl-TAG levels to up to 85 mol% in field-grown transgenic Camelina. Additionally, total moles of triacylglycerol (TAG) per seed increased 20%. Analysis of the acetyl-TAG fraction revealed a twofold reduction in very long chain fatty acids (VLCFA), consistent with their displacement from the sn-3 position by acetate. Seed germination remained high, and seedlings were able to metabolize the stored acetyl-TAGs as rapidly as regular triacylglycerols. Viscosity, freezing point and caloric content of the Camelina acetyl-TAG oils were reduced, enabling use of this oil in several nonfood and food applications.

    There is ample evidence that depression is000  a common comorbid health issue in people with type 1 or type 2 diabetes. Reviews have also concluded that depression in diabetes is associated with higher HbA1c levels, less optimal self-care behaviours, lower quality of life, incident vascular...... complications and higher mortality rates. However, longitudinal studies into the course of depression in people with type 1 diabetes remain scarce. In this issue of Diabetologia, Kampling and colleagues (doi: 10.1007/s00125-016-4123-0 ) report the 5 year trajectories of depression in adults with newly diagnosed...... type 1 diabetes (mean age, 28 years).

    Depression is a disease that can dramatically lower quality of life. Symptoms of depression can range from temporary sadness to suicide. Embarrassment, shyness, and the stigma of depression are some of the factors preventing people from getting help for their problems. Contemporary social media technologies like Internet forums or micro-blogs give people the opportunity to talk about their feelings in a confidential anonymous environment. However, many participants in such networks may not recognize the severity of their depression and their need for professional help. Our approach is to develop a method that detects symptoms of depression in free text, such as posts in Internet forums, chat rooms and the like. This could help people appreciate the significance of their depression and realize they need to seek help. In this work Natural Language Processing methods are used to break the textual information into its grammatical units. Further analysis involves detection of depression symptoms and their frequency with the help of words known as indicators of depression and their synonyms. Finally, similar to common paper-based depression scales, e.g., the CES-D, that information is incorporated into a single depression score. In this evaluation study, our depressive mood detection system, DepreSD (Depression Symptom Detection), had an average precision of 0.84 (range 0.72-1.0 depending on the specific measure) and an average F measure of 0.79 (range 0.72-0.9).

  12. Objective Methods for Reliable Detection of Concealed Depression

    2015-04-01

    Full Text Available Recent research has shown that it is possible to automatically detect clinical depression from audio-visual recordings. Before considering integration in a clinical pathway, a key question that must be asked is whether such systems can be easily fooled. This work explores the potential of acoustic features to detect clinical depression in adults both when acting normally and when asked to conceal their depression. Nine adults diagnosed with mild to moderate depression as per the Beck Depression Inventory (BDI-II and Patient Health Questionnaire (PHQ-9 were asked a series of questions and to read a excerpt from a novel aloud under two different experimental conditions. In one, participants were asked to act naturally and in the other, to suppress anything that they felt would be indicative of their depression. Acoustic features were then extracted from this data and analysed using paired t-tests to determine any statistically significant differences between healthy and depressed participants. Most features that were found to be significantly different during normal behaviour remained so during concealed behaviour. In leave-one-subject-out automatic classification studies of the 9 depressed subjects and 8 matched healthy controls, an 88% classification accuracy and 89% sensitivity was achieved. Results remained relatively robust during concealed behaviour, with classifiers trained on only non-concealed data achieving 81% detection accuracy and 75% sensitivity when tested on concealed data. These results indicate there is good potential to build deception-proof automatic depression monitoring systems.

    To compare depressive symptoms among medical students taught using problem-based learning (PBL) and the traditional method. Beck's Depression Inventory was applied to 215 medical students. The prevalence of depression was calculated as the number of individuals with depression divided by the total number in the sample from each course, with 95% confidence intervals. The statistical significance level used was 5% (p ≤ .05). Among the 215 students, 52.1% were male and 47.9% were female; and 51.6% were being taught using PBL methodology and 48.4% using traditional methods. The prevalence of depression was 29.73% with PBL and 22.12% with traditional methods. There was higher prevalence among females: 32.8% with PBL and 23.1% with traditional methods. The prevalence of depression with PBL among students up to 21 years of age was 29.4% and among those over 21 years, 32.1%. With traditional methods among students up to 21 years of age, it was 16.7%%, and among those over 21 years, 30.1%. The prevalence of depression with PBL was highest among students in the second semester and with traditional methods, in the eighth. Depressive symptoms were highly prevalent among students taught both with PBL and with traditional methods.

Super cooling points and freezing points were assayed to understand the cold hardiness of these two parasitoids. The results indicated that Asecodes hispinarum and Tetrastichus brontispae had considerable high cold-resistance. They could survive in the areas where B. Longissima are distributing. Both super cooling points and freezing points were different between A. Hispinarum and T. Brontispae. Either super cooling points or freezing points were the highest in pupae stage of these two parasitoids. However, there were no differences in super cooling points and freezing points between female and male insects. Asecodes hispinarum and Tetrastichus brontispae could be applied in the distribution areas of coconut leaf beetles in China.

    A variety of methods have been developed to process digital elevation models (DEMs) in order to extract morphological properties of land surfaces. Almost all rely on depression filling to facilitate drainage analysis. This study proposes an intuitive and relatively simple depression-filling algorithm, which is readily applicable to raster and irregular datasets. In this study, topographic data of two watershed areas were provided to test the capability of this new algorithm. The results show that the proposed algorithm can accurately identify the locations of depressions and efficiently assign pseudo flow directions across the filled depressions.

    To analyze the effect of the 'Exercise Without Movement' (E.W.M) yoga method on mindfulness and on the improvement of anxiety and depression symptoms. A quasi-experimental study examined the effect of one month E.W.M. intervention among 38 participants who were enrolled voluntarily to both groups, study (n = 16) and control (n = 22). Five participants dropped out during the study. The State Mindfulness Scale (SMS) was used to measure mindfulness. The Anxiety Inventory Beck (BAI) and the Beck Depression Inventory (BDI-II) were used to measure the anxiety and depression symptoms, respectively, before and after the intervention. Study group showed both a statistically significant increase in mindfulness and decrease in anxiety and depression symptoms, compared with the control group. The E.W.M. has been useful in the development of mindfulness and in the treatment of anxiety and depression symptoms and may represent a new method in the mindfulness-based therapeutic application.

    Full Text Available Abstract Background Obesity is often comorbid with depression and individuals with this comorbidity fare worse in behavioral weight loss treatment. Treating depression directly prior to behavioral weight loss treatment might bolster weight loss outcomes in this population, but this has not yet been tested in a randomized clinical trial. Methods and design This randomized clinical trial will examine whether behavior therapy for depression administered prior to standard weight loss treatment produces greater weight loss than standard weight loss treatment alone. Obese women with major depressive disorder (N = 174 will be recruited from primary care clinics and the community and randomly assigned to one of the two treatment conditions. Treatment will last 2 years, and will include a 6-month intensive treatment phase followed by an 18-month maintenance phase. Follow-up assessment will occur at 6-months and 1- and 2 years following randomization. The primary outcome is weight loss. The study was designed to provide 90% power for detecting a weight change difference between conditions of 3.1 kg (standard deviation of 5.5 kg at 1-year assuming a 25% rate of loss to follow-up. Secondary outcomes include depression, physical activity, dietary intake, psychosocial variables and cardiovascular risk factors. Potential mediators (e.g., adherence, depression, physical activity and caloric intake of the intervention effect on weight change will also be examined. Discussion Treating depression before administering intensive health behavior interventions could potentially boost the impact on both mental and physical health outcomes.

    Full Text Available Abstract Background A medication information intervention was delivered to patients with a major depressive episode prior to psychiatric hospital discharge. Methods The objective of this study was to explore how patients evolved after hospital discharge and to identify factors influencing this evolution. Using a quasi-experimental longitudinal design, the quantitative analysis measured clinical (using the Hospital Anxiety and Depression Scale, the somatic dimension of the Symptom Checklist 90 and recording the number of readmissions and humanistic (using the Quality of Life Enjoyment and Satisfaction Questionnaire outcomes of patients via telephone contacts up to one year following discharge. The qualitative analysis was based on the researcher diary, consisting of reports on the telephone outcome assessment of patients with major depression (n = 99. All reports were analyzed using the thematic framework approach. Results The change in the participants' health status was as diverse as it was at hospital discharge. Participants reported on remissions; changes in mood; relapses; and re-admissions (one third of patients. Quantitative data on group level showed low anxiety, depression and somatic scores over time. Three groups of contributing factors were identified: process, individual and environmental factors. Process factors included self caring process, medical care after discharge, resumption of work and managing daily life. Individual factors were symptom control, medication and personality. Environmental factors were material and social environment. Each of them could ameliorate, deteriorate or be neutral to the patient's health state.

    Full Text Available A limited number of biomarkers in the central and peripheral systems which are known may be useful for diagnosing major depressive disorders and predicting the effectiveness of antidepressant treatments. Since 60% of depressed patients do not respond adequately to medication or are resistant to antidepressants, it is imperative to delineate more accurate biomarkers. Recent clinical studies suggest that β-arrestin 1 levels in human mononuclear leukocytes may be an efficient biomarker. If potential biomarkers such as β-arrestin 1 could be assessed from a source such as peripheral blood cells, then they could be easily monitored and used to predict therapeutic responses. However, no previous studies have measured β-arrestin 1 levels in peripheral blood mononuclear cells (PBMCs in anxious-depressive rodents.This study aimed to develop a method to detect β-arrestin protein levels through immunoblot analyses of mouse PBMCs isolated from whole blood. In order to validate the approach, β-arrestin levels were then compared in naïve, anxious/depressed mice, and anxious/depressed mice treated treated with a selective serotonin reuptake inhibitor (SSRI; fluoxetine, 18 mg/kg/day in the drinking water. The results demonstrated that mouse whole blood collected by submandibular bleeding permitted isolation of enough PBMCs to assess circulating proteins such as β-arrestin 1. β-arrestin 1 levels were successfully measured in healthy human subject and naïve mouse PBMCs. Interestingly, PBMCs from anxious/depressed mice showed significantly reduced β-arrestin 1 levels. These decreased β-arrestin 1 expression levels were restored to normal levels with chronic fluoxetine treatment. The results suggest that isolation of PBMCs from mice by submandibular bleeding is a useful technique to screen putative biomarkers of the pathophysiology of mood disorders and the response to antidepressants. In addition, these results confirm that β-arrestin 1 is a potential

    Full Text Available Introduction. Repetitive transcranial magnetic stimulation (rTMS is a method of brain stimulation which is increasingly used in both clinical practice and research. Up-to-date studies have pointed out a potential antidepressive effect of rTMS, but definitive superiority over placebo has not yet been confirmed. Objective. The aim of the study was to examine the effect of rTMS as an adjuvant treatment with antidepressants during 18 weeks of evaluation starting from the initial application of the protocol. Methods. Four patients with the diagnosis of moderate/severe major depression were included in the study. The protocol involved 2000 stimuli per day (rTMS frequency of 10 Hz, intensity of 120% motor threshold administered over the left dorsolateral prefrontal cortex (DLPFC for 15 days. Subjective and objective depressive symptoms were measured before the initiation of rTMS and repeatedly evaluated at week 3, 6, 12 and 18 from the beginning of the stimulation. Results. After completion of rTMS protocol two patients demonstrated a reduction of depressive symptoms that was sustained throughout the 15-week follow-up period. One patient showed a tendency of remission during the first 12 weeks of the study, but relapsed in week 18. One patient showed no significant symptom reduction at any point of follow-up. Conclusion. Preliminary findings suggest that rTMS has a good tolerability and can be efficient in accelerating the effect of antidepressants, particularly in individuals with shorter duration of depressive episodes and moderate symptom severity.

    Despite extensive research, the link between etiological factors and depression remains poorly understood. This may in part be due to a focus on strictly linear definitions of causality, derived at the group level. However, etiological relations in depression are likely to be dynamical, nonlinear and potentially unquantifiable with traditional statistics. Therefore the aim of this study was to evaluate the use of the convergent cross-mapping (CCM) method in investigating possible nonlinear relationships between supposed etiological factors and depressive symptomatology. Time series data from six healthy individuals were used to model the relationship between 24-h urinary free cortisol and negative affect using CCM and dewdrop embeddings. CCM is a nonlinear measure of causality, based on state space reconstruction with lagged coordinate embeddings. The results showed that nonlinear dynamical relationships between cortisol and negative affect may be present within participants, as demonstrated by a positive cross-map convergence from negative affect to cortisol. However, analyses also showed that noise and influential points had considerable impact on the results. Convergent crossmapping can be used to reveal possible nonlinear dynamical relationships between etiological factors and psychopathology that may remain undetected with traditional linear causality measures.

  11. A simple method to account for natural selection when predicting inbreeding depression.

    It has been widely appreciated that natural selection opposes the progress of inbreeding in small populations, thus limiting the actual inbreeding depression for fitness traits. However, no method to account for the consequences of this process has been given so far. I give a simple and intuitive method to predict inbreeding depression, taking into account the increase in selection efficiency against recessive alleles during inbreeding. It is based on the use of a "purged inbreeding coefficient" g(t) that accounts for the reduction of the probability of the deleterious homozygotes caused by the excess d of detrimental effect for deleterious alleles in the homozygous condition over its additive expectation. It is shown that the effect of purging can be important even for relatively small populations. For between-loci variable deleterious effects, accurate predictions can be obtained using the effective homozygous deleterious excess d(e), which can be estimated experimentally and is robust against variation of the ancestral effective population size. The method can be extended to any trait and it is used to predict the evolution of the mean viability or fecundity in a conservation program with equal or random family contributions.

    Rainfall partition on paved urban surfaces is governed to a great extent by depression storage. This is especially the case for small rainfall events, which are often ignored in urban hydrology. If storage, infiltration and evaporation (important for urban heat island mitigation), rather than storm water run-off, are of interest, high-resolution simulations with exact values for depression storage capacities are required. Terrestrial laser scanners deliver fast, high-resolution surveys of pavement surface morphology. The depression storage capacity can be quantified from 3D points by generating digital elevation models and applying cut-and-fill algorithms in a geographic information system. The method was validated using a test model. It was possible to quantify depressions with a depth of at least 1.4 × 10(-3) m and a surface of at least 15 × 10(-6) m(2) with an uncertainty below 30%. Applying this method, the depression storage capacities for 11 ideal, typical pavement designs were found to vary from 0.07 to 1.4 mm. Realistic urban pavements must also be surveyed, as cracks and puddles from their use history can have a major impact on the depression storage capacities and thus on infiltration, evaporation and, finally, the annual run-off.

    Full Text Available Abstract Background Missing data present a challenge to many research projects. The problem is often pronounced in studies utilizing self-report scales, and literature addressing different strategies for dealing with missing data in such circumstances is scarce. The objective of this study was to compare six different imputation techniques for dealing with missing data in the Zung Self-reported Depression scale (SDS. Methods 1580 participants from a surgical outcomes study completed the SDS. The SDS is a 20 question scale that respondents complete by circling a value of 1 to 4 for each question. The sum of the responses is calculated and respondents are classified as exhibiting depressive symptoms when their total score is over 40. Missing values were simulated by randomly selecting questions whose values were then deleted (a missing completely at random simulation. Additionally, a missing at random and missing not at random simulation were completed. Six imputation methods were then considered; 1 multiple imputation, 2 single regression, 3 individual mean, 4 overall mean, 5 participant's preceding response, and 6 random selection of a value from 1 to 4. For each method, the imputed mean SDS score and standard deviation were compared to the population statistics. The Spearman correlation coefficient, percent misclassified and the Kappa statistic were also calculated. Results When 10% of values are missing, all the imputation methods except random selection produce Kappa statistics greater than 0.80 indicating 'near perfect' agreement. MI produces the most valid imputed values with a high Kappa statistic (0.89, although both single regression and individual mean imputation also produced favorable results. As the percent of missing information increased to 30%, or when unbalanced missing data were introduced, MI maintained a high Kappa statistic. The individual mean and single regression method produced Kappas in the 'substantial agreement' range

    The multichannel analysis of surface-wave method (MASW) is a newly development method. The method has been employed in various applications in environmental and engineering geophysics overseas. However, It can only be found a few case studies in China. Most importantly, there is no application of the MASW in desert area in China or abroad. We present a case study of investigating the low-depression velocity in Temple of North Taba Area in Erdos Basin. The MASW method successfully defined the low-depression velocity layer in the desert area. Comparing results obtained by the MASW method with results by refraction seismic method, we discussed efficiency and simplicity of applying the MASW method in the desert area. It is proved that the maximum investigation depth can reach 60m in the study area when the acquisition and procession parameters are carefully chosen. The MASW method can remedy the incompetence of the refraction method and the micro-seismograph log method in low-depression velocity layer's investigation. The MASW method is also a powerful tool in investigation of near-surface complicated materials and possesses many unique advantages.

    In depression, the ability to experience daily life positive affect predicts recovery and reduces relapse rates. Interventions based on the experience sampling method (ESM-I) are ideally suited to provide insight in personal, contextualized patterns of positive affect. The aim of this study was to examine whether add-on ESM-derived feedback on personalized patterns of positive affect is feasible and useful to patients, and results in a reduction of depressive symptomatology. Depressed outpatients (n=102) receiving pharmacological treatment participated in a randomized controlled trial with three arms: an experimental group receiving add-on ESM-derived feedback, a pseudo-experimental group participating in ESM but receiving no feedback, and a control group. The experimental group participated in an ESM procedure (three days per week over a 6-week period) using a palmtop. This group received weekly standardized feedback on personalized patterns of positive affect. Hamilton Depression Rating Scale – 17 (HDRS) and Inventory of Depressive Symptoms (IDS) scores were obtained before and after the intervention. During a 6-month follow-up period, five HDRS and IDS assessments were completed. Add-on ESM-derived feedback resulted in a significant and clinically relevant stronger decrease in HDRS score relative to the control group (p<0.01; −5.5 point reduction in HDRS at 6 months). Compared to the pseudo-experimental group, a clinically relevant decrease in HDRS score was apparent at 6 months (B=−3.6, p=0.053). Self-reported depressive complaints (IDS) yielded the same pattern over time. The use of ESM-I was deemed acceptable and the provided feedback easy to understand. Patients attempted to apply suggestions from ESM-derived feedback to daily life. These data suggest that the efficacy of traditional passive pharmacological approach to treatment of major depression can be enhanced by using person-tailored daily life information regarding positive affect.

    To develop and psychometrically assess a short instrument that can be easily used in clinical practice to measure knowledge-seeking behavior in patients suffering from depression. We developed the knowledge seeking instrument (KSI), a self-report scale of three items to assess the number of hours spent in knowledge seeking behavior such as reading written materials, surfing the internet, or watching audio-visual tools. Experts in mood disorders (n=12) participated in the formal validity assessment of the instrument, and the developed instrument was administered to outpatients who were attending psychiatry clinic (n=63). All patients also completed a multiple choice question instrument to measure knowledge of depression, a Likert self report questionnaire to assess attitudes towards depression and its treatment, and an adherence to antidepressants scale. In addition to the empirical evidence for validity, there was 68% agreement among experts that the items were highly relevant in measuring behavior of knowledge seeking, providing evidence for content validity. There were significant correlations (pknowledge of psychological and biological treatments of depression and knowledge seeking reading scores. The internal consistency reliability (Cronbach's alpha) was 0.67 for the instrument. The KSI takes 2 min to complete. There is evidence for reliability, content, and criterion based concurrent validities. The KSI can be utilized to assess knowledge seeking behavior in patients with depression.

HIV-infected pregnant Thai women (n = 40) were randomly assigned to either the control or the intervention group. A registered nurse provided telephone support to the intervention group. Depressive symptoms were measured at three points in both groups. In-depth interviews were conducted at Time 2 and Time 3. Results show that depressive symptoms in the intervention group decreased over time. Qualitative results describe how telephone support can work, but also reveal that telephone support did not work for everyone. We recommend that a larger mixed methods study be conducted to examine the effects of telephone support on depressive symptoms among HIV-infected women, including the costs and benefits of such support.

    Full Text Available Background. Due to an increasing number of elderly people suffering from major depression and potential side effects of the prescribed drugs, the introduction of new therapeutic approaches is needed. Currently, in Germany, auricular acupuncture is no part of clinical care for gerontopsychiatric patients. Based on promising clinical experiences and existing evidence for treating addiction and trauma, a benefit of auricular acupuncture integrated in existing treatment programs in elderly patients may be hypothesized. Within this project auricular acupuncture according to the National Acupuncture Detoxification Association (NADA will be integrated in the multimodal treatment regime for elderly patients with major depression in a daytime ward setting. Methods/Design. To evaluate the feasibility and acceptance a mixed method approach is used. In a day clinic, a sample of 20 psychogeriatric patients with the diagnosis of major depression will be enrolled. The patients will receive a total of nine auricular acupuncture treatments according to the standardized NADA protocol in a group setting. The therapeutic process, its organization, the experience, and the willingness of patients to participate will be evaluated by interviews with patients and the therapeutic team. Data will be analyzed qualitatively using content analysis. Additionally, quantitative outcome parameters will be measured by standardized questionnaires.

    Full Text Available Background: Symptoms of depression are often reported among patients with a cancer diagnosis. Strong sense of coherence (SOC is shown to be associated with less depression in the general older population and among nursing homes (NH residents in particular. Knowledge about mixed-methods perspectives that examine symptoms of depression and SOC among cognitively intact NH residents with cancer is scarce. Aim: To investigate symptoms of depression and SOC among NH residents who are cognitively intact and have cancer. Methods: We used a quantitatively driven mixed-methods design with sequential supplementary qualitative components. We facilitated the collection of quantitative survey data of 60 NH residents (≥ 65 years with cancer using the Geriatric Depression Scale (GDS and SOC scale. The supplementary psychosocial component comprised qualitative research interviews about experiences related to depression with nine respondents from the same cohort. Results: In fully adjusted multiple regression analysis of the sociodemographic variables, the GDS was significantly correlated with SOC (P < 0.001. The experience of sadness was identified by the following theme: sadness. Coping with the experience of symptoms of depression was dominated by coping with sadness. Conclusion: More than half the NH residents reported symptoms of depression, and the SOC was associated with reduced symptoms. A mixed-methods design contributed to nuanced and detailed information about the meaning of depression, and the supplementary component informs and supports the core component. To improve the situation of NH residents with cancer, more attention should be paid to the residents’ experience of symptoms of depression and their SOC.

  13. Goethe's anxieties, depressive episodes and (self-)therapeutic strategies: a contribution to method integration in psychotherapy.

    In psychiatry and psychotherapy, abstract scientific principles need to be exemplified by narrative case reports to gain practical precision. Goethe was one of the most creative writers, productive scientists, and effective statesmen that ever lived. His descriptions of feelings, emotions, and mental states related to anxieties, depressive episodes, dysthymia, and creativity are unique in their phenomenological precision and richness. His life and work can thus serve as an excellent example enhancing our understanding of the relationship between anxiety, depression and creativity. Furthermore, he described (self-)therapeutic strategies that reinforce and refine modern views. Goethe's self-assessments in his works and letters, and the descriptions by others are analyzed under the perspective of current psychiatric classification. His therapeutic techniques and recommendations are compared with cognitive-behavioral, psychodynamic, and existential psychotherapy to amplify modern concepts of psychotherapy. From a scientific perspective, several distinctive depressive episodes can be diagnosed in Goethe's life. They were characterized by extended depressive moods, lack of drive, and loss of interest and self-esteem combined with social retreat. Goethe displayed diffuse and phobic anxieties as well as dysthymia. His (self-)therapeutic strategies were: (a) the systematic use of helping alliances, (b) behavioral techniques, (c) cognitive reflection on meanings and beliefs, (d) psychodynamic and psychoanalytic remembering, repeating, and working through, and (e) existential striving for self-actualization, social commitment, meaning, and creativity. In Goethe's life, creative incubation, illumination, and elaboration appear to have been associated with psychic instability and dysthymia, sometimes with depressive episodes in a clinical sense. On the one hand, his creative work was triggered by anxieties, dysthymia, and depressive moods. On the other hand, his creativity

    Depression is a worldwide public health problem that requires the attention of qualified health professionals. The training of skilled nurses is a challenge for nursing instructors due to the complexity of this pathology. The aim was to analyse the declarative and argumentative knowledge acquired about depression by students receiving traditional expository instruction versus students receiving problem-based learning instruction. Quasi-experimental study with pre-test and post-test design in experimental and control group to measure differences in the improvement of declarative and argumentative knowledge. Non parametric tests were used to compare the scores between the experimental group and the control group, and between the pre-test and post-test in each group. 114 students participated in the study. Implementation of the study took place during the 2014-2015 academic year in the third year of the Nursing undergraduate degree courses in the University of the Basque Country (UPV/EHU) as part of the Mental Health Nursing subject. The data indicated that there were no statistically significant differences between the two methodologies in regard to declarative knowledge in the care of patients with depression. Nevertheless, the argumentative capacity of the experimental group improved significantly with the problem-based learning methodology (p=0.000). The results of the implementation indicated that problem-based learning was a satisfactory tool for the acquisition of argumentative capacity in depression nursing care. Still, working examples of teaching sequences that bridge the gap between general clinical practice and classroom practice remain an important goal for continuing research in nursing education.

    To provide an overview of methods to identify postnatal depression (PND) in primary care and to assess their validity, acceptability, clinical effectiveness and cost-effectiveness, to model estimates of cost, to assess whether any method meets UK National Screening Committee (NSC) criteria and to identify areas for future research. Searches of 20 electronic databases (including MEDLINE, CINAHL, PsycINFO, EMBASE, CENTRAL, DARE and CDSR), forward citation searching, personal communication with authors and searching of reference lists. A generalised linear mixed model approach to the bivariate meta-analysis was undertaken for the validation review with quality assessment using QUADAS. Within the acceptability review, a textual narrative approach was employed to synthesise qualitative and quantitative research evidence. For the clinical and cost-effectiveness reviews methods outlined by the Centre for Reviews and Dissemination and the Cochrane Collaboration were followed. Probabilistic models were developed to estimate the costs associated with different identification strategies. The Edinburgh Postnatal Depression Scale (EPDS) was the most frequently explored instrument across all of the reviews. In terms of test performance, postnatally the EPDS performed reasonably well: sensitivity ranged from 0.60 (specificity 0.97) to 0.96 (specificity 0.45) for major depression only; from 0.31 (specificity 0.99) to 0.91 (specificity 0.67) for major or minor depression; and from 0.38 (specificity 0.99) to 0.86 (specificity 0.87) for any psychiatric disorder. Evidence from the acceptability review indicated that, in the majority of studies, the EPDS was acceptable to women and health-care professionals when women were forewarned of the process, when the EPDS was administered in the home, with due attention to training, with empathetic skills of the health visitor and due consideration to positive responses to question 10 about self-harm.

    of this work was to compare reference methodologies to Fourier transform infrared spectroscopy for analysis of pH and freezing point (FP under different storage conditions on samples of raw bovine milk. Milk samples were collected from bulk tank milk on 57 farms. Each sample was subdivided into 45 vials (40 mL which were distributed according to storage temperature (-20ºC, 7ºC and 25ºC, age of the sample (0, 3, 6 and 9 days and levels of water addition (0, 2, 4 and 6%. Bronopol was added into 44 flasks and one was maintained without addition of preservative for control. Frozen point and pH were determined by the standard methods (thermistor cryoscope and potentiometer, respectively and by the alternative methodology by using MilkoScanTM FT+. The results from each method, at different conditions of conservation of the samples, were evaluated by analysis of variance and comparison of means. The linear regression analysis was performed to evaluate the methodologies (reference and alternative for results of the frozen point in function of the age of the sample. Bronopol did not alter pH means, but it reduced frozen point. Correction factors were calculated to eliminate this effect on the results of the frozen point. Means of pH in three-day samples, kept at -20ºC and 25ºC were lower than the samples at 7ºC. The age of the samples affected the results of pH when they were submitted to 25ºC. The increase of storage temperature to 25ºC reduced means of frozen point in samples without addition of water and at nine days of storage. The increase in age of sample at -20ºC and 7ºC does not affect means of frozen point. There is a strong correlation among methodologies in function of age of the sample for frozen point.

    A growing body of research has demonstrated links between sleep problems and symptoms of depression and anxiety in community and clinical samples of adolescents and young adults. Scant longitudinal research, however, has examined reciprocal associations over socio-contextual shifts such as the transition to college. Using multiple methods of assessment (e.g., actigraphy, subjective report), the current study assessed whether sleep quantity, quality or variability changed over the transition to college and investigated the potential cross-lagged relationships between adolescents' sleep and symptoms of anxiety and depression. The participants (N = 82; 24% male) were studied at three time points over approximately 1 year: spring of their senior year of high school (T1), fall of their first year of college (T2), and spring of their first year of college (T3). Sleep minutes, sleep efficiency, wake time variability and anxiety increased over the transition to college. Subjective reports of sleep problems decreased. Cross-lagged panel models indicated significant relationships between subjective sleep quality and anxiety symptoms over time where subjective sleep problems at T1 were associated with anxiety at T2, and anxiety at T2 was associated with subjective sleep problems at T3. In contrast, greater depressive symptoms at T1 preceded increases in subjective sleep problems, sleep latency and sleep start time variability at T2. Importantly, there were concurrent associations between symptoms of anxiety or depression at T2 and sleep efficiency, sleep start time variability, and subjective sleep problems. These findings suggest that, overall, sleep quantity and quality improved over the transition to college, although the overall amounts of sleep were still below developmental recommendations. However, for some youth, the first semester of college may be a sensitive period for both sleep problems and symptoms of anxiety. In contrast, depressive symptoms were stable across

    Psychosocial stress can cause mental conditions such as depression in humans. To develop drug therapies for the treatment of depression, it is necessary to use animal models of depression to screen drug candidates that exhibit anti-depressive effects. Unfortunately, the present methods of drug screening for antidepressants, the forced-swim test and tail-suspension test, are limiting factors in drug discovery because they are not based on the constructive validity of objective phenotypes in depression. Previously, we discovered that the onset of nest building is severely delayed in mice exposed to subchronic mild social defeat stress (sCSDS). Therefore, a novel paradigm combining acute social defeat stress (ASDS) and the nest-building test (SNB) were established for the efficient screening of drugs for depressive-like symptoms. Since ASDS severely delayed the nest-building process as shown in chronically social defeated mice, we sought to rescue the delayed nest-building behavior in ASDS mice. Injecting a specific serotonin 2a receptor antagonist (SR-46349B), the nest-building deficit exhibited by ASDS mice was partially rescued. On the other hand, a selective serotonin reuptake inhibitor (fluoxetine) did not rescue the nest-building deficit in ASDS mice. Therefore, we conclude that the SNB paradigm is an another potential behavioral method for screening drugs for depressive-like symptoms including attention deficit, anxiety, low locomotion, and decreased motivation.

    2005-01-01

    In order to observe the therapeutic effects of the brain-resuscitation acupuncture method for post wind-stroke mental depression, 90 such cases were randomly divided into two groups, each consisting of 45 cases. For the treatment group, the brain-resuscitation acupuncture method was adopted, with Neiguan (PC 6), Renzhong (GV 26), Sanyinjiao (SP 6), Baihui (GV 20), and Shenmen (HT 7) selected as the main points. For the control group, oral medication of Fluoxetine was prescribed. Therapeutic effects and changes in the HAMD integrals of the two groups were observed. The total effective rate in the treatment group was 77.7%, and that in the control group was 75.1%, showing no significant difference between the two groups (P>0.05). The average effect starting time of the treatment group was 11.58±4.89 days, while that of the control group was 15.96±6.50 days, showing a significant difference between the two groups (P<0.05). It can be concluded that for the post wind-stroke mental depression, the brain-resuscitation acupuncturemethod may show a good and quicker therapeutic effect with no side effects as compared with pharmacotherapy.

    The authors compared various strategies for recruiting elderly subjects with bereavement-related depression into a randomized clinical trial. Over 5 years, they empaneled 65 patients from a total of 441 subjects screened (14.7%). Response to media advertisements was the single most effective strategy (54% of subjects). Another effective, but labor-intensive, strategy was using letters to bereaved spouses found through newspaper obituaries (14%); another 14% were referred by friends who had seen study advertisements. Information letters to healthcare providers yielded no study participants. Pathways to study participation did not differ as a function of race or gender and did not influence study retention or remission rates. Our experience suggests that successful intake depends on a personal mode of recruitment.

    BACKGROUND: The comorbidity of type 2 diabetes mellitus (T2DM) and depression is associated with poor glycemic control. Exercise has been shown to improve mood and glycemic control, but individuals with comorbid T2DM and depression are disproportionately sedentary compared to the general population and report more difficulty with exercise. Behavioral activation, an evidence-based depression psychotherapy, was designed to help people with depression make gradual behavior changes, and may be helpful to build exercise adherence in sedentary populations. This pilot randomized clinical trial will test the feasibility of a group exercise program enhanced with behavioral activation strategies among women with comorbid T2DM and depression. METHODS/DESIGN: Sedentary women with inadequately controlled T2DM and depression (N=60) will be randomly assigned to one of two conditions: exercise or usual care. Participants randomized to the exercise condition will attend 38 behavioral activation-enhanced group exercise classes over 24 weeks in addition to usual care. Participants randomized to the usual care condition will receive depression treatment referrals and print information on diabetes management via diet and physical activity. Assessments will occur at baseline and 3-, 6-, and 9-months following randomization. The goals of this pilot study are to demonstrate feasibility and intervention acceptability, estimate the resources and costs required to deliver the intervention and to estimate the standard deviation of continuous outcomes (e.g., depressive symptoms and glycosylated hemoglobin) in preparation for a fully-powered randomized clinical trial. DISCUSSION: A novel intervention that combines exercise and behavioral activation strategies could potentially improve glycemic control and mood in women with comorbid type 2 diabetes and depression. TRIAL REGISTRATION: NCT01024790.

    In the United Kingdom, ethnic minority group's particularly British South Asian women have higher rates of depression than their white counterparts. Despite this they remain under represented in mental health trials. Whilst the US legislation mandates the inclusion of ethnic minorities into research, there are no similar initiatives in the UK. Barriers in recruiting these hard to reach ethnic groups are cited as major reasons behind this under representation. Once these barriers are encountered it becomes a challenge for the researchers to overcome them. As there is paucity of research in this specific area through this paper we want to share our strategies in recruiting British South Asians thus encouraging other researchers to consider ethnic minority inclusion into research. Our published systematic review on the barriers to recruitment of ethnic minority participants into mental health research developed a typology of thirty three ethnic recruitment barriers described under five themes. We aimed to find strategies to overcome these barriers from five depression trials for British South Asians conducted by our research group. Firstly we extracted data on recruitment strategies from the published papers. Later researchers involved in these five trials formed a working group to add to these extracted strategies. Finally these strategies were matched to the individual barriers described in the typology. Multiple recruitment strategies were described by the researchers. These strategies were matched to all but two recruitment barriers related to psychopathology/substance misuse by the participants and paucity of healthcare related resources. Multiple strategies were found to be effective against each barrier and appropriate ones could be selected by the researchers after considering available resources at hand. Findings from this paper have implications for the design of recruitment strategies for hard to recruit ethnic minority groups to health care research. There

    We have measured the difference in electronic structure factors between liquid H(2)O and D(2)O at temperatures of 268 and 273 K with high energy x-ray diffraction. These are compared to our previously published data measured from 279 to 318 K. We find that the total structural isotope effect increases by a factor of 3.5 over the entire range, as the temperature is decreased. Structural isochoric temperature differential and isothermal density differential functions have been used to compare these data to a thermodynamic model based upon a simple offset in the state function. The model works well in describing the magnitude of the structural differences above approximately 310 K, but fails at lower temperatures. The experimental results are discussed in light of several quantum molecular dynamics simulations and are in good qualitative agreement with recent temperature dependent, rotationally quantized rigid molecule simulations.

    Full Text Available Abstract Background Mindfulness Based Cognitive Therapy (MBCT is an 8-week course developed for patients with relapsing depression that integrates mindfulness meditation practices and cognitive theory. Previous studies have demonstrated that non-depressed participants with a history of relapsing depression are protected from relapse by participating in the course. This exploratory study examined the acceptability and effectiveness of MBCT for patients in primary care with active symptoms of depression and anxiety Methods 13 patients with recurrent depression or recurrent depression and anxiety were recruited to take part in the study. Semi-structured qualitative interviews were conducted three months after completing the MBCT programme. A framework approach was used to analyse the data. Beck depression inventories (BDI-II and Beck anxiety inventories (BAI provided quantitative data and were administered before and three months after the intervention. Results The qualitative data indicated that mindfulness training was both acceptable and beneficial to the majority of patients. For many of the participants, being in a group was an important normalising and validating experience. However most of the group believed the course was too short and thought that some form of follow up was essential. More than half the patients continued to apply mindfulness techniques three months after the course had ended. A minority of patients continued to experience significant levels of psychological distress, particularly anxiety. Statistically significant reductions in mean depression and anxiety scores were observed; the mean pre-course depression score was 35.7 and post-course score was 17.8 (p = 0.001. A similar reduction was noted for anxiety with a mean pre-course anxiety score of 32.0 and mean post course score of 20.5 (p = 0.039. Overall 8/11 (72% patients showed improvements in BDI and 7/11 (63% patients showed improvements in BAI. In general the results

    Forty percent of residents living in care homes in the United Kingdom have significant depressive symptoms. Care homes can appear to be depressing places, but whether the physical environment of homes directly affects depression in care home residents is unknown. This study explores the relationship between the physical environment and depressive symptoms of older people living in care homes. In a prospective cohort study the physical environment of 50 care homes were measured using the Sheffield Care Environment Assessment Matrix (SCEAM) and depressive symptoms of 510 residents measured using the Geriatric Depression Scale (GDS-15). The study was supplemented with semi-structured interviews with residents living in the care homes. Quantitative data were analyzed using multi-level modeling, and qualitative data analyzed using a thematic framework approach. The overall physical environment of care homes (overall SCEAM score) did not predict depressive symptoms. Controlling for dependency, social engagement, and home type, having access to outdoor space was the only environmental variable to significantly predict depressive symptoms. Residents interviewed reported that access to outdoor space was restricted in many ways: locked doors, uneven foot paths, steep steps, and needing permission or assistance to go outside. We provide new evidence to suggest that access to outdoor space predicts depressive symptoms in older people living in care home. Interventions aimed at increasing access to outdoor spaces could positively affect depressive symptoms in older people.

    Major depressive disorder (MDD) is a common, debilitating chronic condition in the United States and worldwide. Particularly in women, depressive symptoms are often accompanied by high levels of stress and ruminations, or repetitive self-critical negative thinking. There is a research and clinical imperative to evaluate complementary therapies that are acceptable and feasible for women with depression and that target specific aspects of depression in women, such as ruminations. To begin to address this need, we conducted a randomized, controlled, mixed-methods community-based study comparing an 8-week yoga intervention with an attention-control activity in 27 women with MDD. After controlling for baseline stress, there was a decrease in depression over time in both the yoga group and the attention-control group, with the yoga group having a unique trend in decreased ruminations. Participants in the yoga group reported experiencing increased connectedness and gaining a coping strategy through yoga. The findings provide support for future large scale research to explore the effects of yoga for depressed women and the unique role of yoga in decreasing rumination.

    Chronic stress as well as major depressive disorders is associated with cortisol metabolism. Two enzymes modulate cortisol (F) and cortisone (E) interconversion: 11β-hydroxysteroid dehydrogenase type 1 and type 2 (11β-HSD1 and 11β-HSD2). Furthermore, F and E were inactivated by 5α and 5β reductases to their tetrahydro-metabolites: tetrahydrocortisol (THF), allo-tetrahydrocortisol (5α-THF) and tetrahydrocortisone (THE). To better understand depression a LC-MS/MS method for simultaneous determination of F, E THF, 5α-THF and THE in human urine has been developed and validated. The quantification range was 0.1-160 ng mL(-1) for F and E, and 0.2-160 ng mL(-1) for the tetrahydro-metabolites, with >86.1% recovery for all analytes. The nocturnal urine concentrations of F, E and tetrahydro-metabolites in 12 apparently healthy male adult volunteers and 12 drug-free male patients (age range, 20-50 years) with a diagnosis of depression were analyzed. A series of significant changes in glucocorticoid metabolism can be detected: F/E ratios and (THF+5α-THF)/THE ratios as well as F and THF concentrations were significantly higher in depression patients than in healthy subjects (p<0.05); 5α-THF/F ratios, 5α-THF/THF ratios as well as 5α-THF concentrations were significantly lower in depression patients (p<0.05). The results pointed to the decreased 11β-HSD2 activity and a dysfunction in the 5α-reductase pathway in depressed patients. This method allows the assessment of 11β-HSD1/2 and 5α/β-reductase activities in a single analytical run providing an innovative tool to explain the potential etiology of depression.

    Full Text Available Introduction: Myocardial infarction (MI is the damage to the heart muscle, or myocardium, resulting from the lack of blood flow to the heart. MI patients experience mental and emotional problems such as depression and anxiety. These complications could cause delay in resuming work, decreased quality of life and increased risk of death. The role of education in facilitating adaptation is very important in these patients. The purpose of this study was to determine the effect of written material and verbal method education on anxiety and depression in patients with myocardial infarction in Urmia hospital in 2009. Methods: This study was a quasi-experimental study, comparing the effect of education on anxiety and depression in patients with myocardial infarction in hospitals affiliated to Urmia University of Medical Science. 124 patients were selected randomly and divided into two groups. The experimental group was educated through face to face training and an educational booklet (Written Material and Verbal Method. The control group did not receive any intervention. The level of anxiety and depression was evaluated, using HADS questionnaire at 3 intervals: after 48 hours of admission, the discharge day and 2 months after discharge. Results: The findings suggested that MI patients were worried about their social role, interpersonal relations and personal health. Such problems can aggravate symptoms and complicate the future care. There was no significant difference between the control and experimental groups before the intervention, but after the intervention, anxiety and depression in the experimental group was significantly less than that in the control group (p<0.05. Conclusion: Considering the beneficial results obtained from written materials and verbal method education on reducing anxiety and depression in cases with myocardial infarction, this may be one of the health care goals. More research on more patients is required to achieve more

    Strategies of personal resilience enable successful adaptation in adversity. Among patients experiencing depression symptoms, we explored which personal resilience strategies they find most helpful and tested the hypothesis that use of these strategies improves depression recovery. We used interview and survey data from the Diagnosis, Management and Outcomes of Depression in Primary Care 2005 cohort of patients experiencing depression symptoms in Victoria, Australia. A total of 564 participants answered a computer-assisted telephone interview question at 12 months follow-up, about what they found most helpful for their depression, stress or worries. Depressive disorder and severity were measured at annual follow-up using the Composite International Diagnostic Interview and the Patient Health Questionnaire self-rating questionnaire. Using interview responses, we categorised participants as users or not of strategies of personal resilience, specifically, drawing primarily on expanding their own inner resources or pre-existing relationships: 316 (56%) were categorised as primarily users of personal resilience strategies. Of these, 193 (61%) reported expanding inner resources, 79 (25%) drawing on relationships and 44 (14%) reported both. There was no association between drawing on relationships and depression outcome. There was evidence supporting an association between expanding inner resources and depression outcome: 25 per cent of users having major depressive disorder 1 year later compared to 38 per cent of non-users (adjusted odds ratio: 0.59, confidence interval: 0.36-0.97). This is the first study to show improved outcome for depression for those who identify as most helpful the use of personal resilience strategies. The difference in outcome is important as expanding inner resources includes a range of low intensity, yet commonly available strategies. © The Author(s) 2014.

    The aim of the present study was to examine the possibility of screening apprehensive pregnant women and mothers at risk for post-partum depression from an analysis of the textual data in the Mother and Child Handbook by using the text-mining method. Uncomplicated pregnant women (n = 58) were divided into two groups according to State-Trait Anxiety Inventory grade (high trait [group I, n = 21] and low trait [group II, n = 37]) or Edinburgh Postnatal Depression Scale score (high score [group III, n = 15] and low score [group IV, n = 43]). An exploratory analysis of the textual data from the Maternal and Child Handbook was conducted using the text-mining method with the Word Miner software program. A comparison of the 'structure elements' was made between the two groups. The number of structure elements extracted by separated words from text data was 20 004 and the number of structure elements with a threshold of 2 or more as an initial value was 1168. Fifteen key words related to maternal anxiety, and six key words related to post-partum depression were extracted. The text-mining method is useful for the exploratory analysis of textual data obtained from pregnant woman, and this screening method has been suggested to be useful for apprehensive pregnant women and mothers at risk for post-partum depression. © 2016 Japan Society of Obstetrics and Gynecology.

    Despite increased depression in adolescents with Autism Spectrum Disorder (ASD), effective prevention approaches for this population are limited. A mixed methods pilot randomised controlled trial (N = 29) of the evidence-based Resourceful Adolescent Program-Autism Spectrum Disorder (RAP-A-ASD) designed to prevent depression was conducted in schools with adolescents with ASD in years 6 and 7. Quantitative results showed significant intervention effects on parent reports of adolescent coping self-efficacy (maintained at 6 month follow-up) but no effect on depressive symptoms or mental health. Qualitative outcomes reflected perceived improvements from the intervention for adolescents' coping self-efficacy, self-confidence, social skills, and affect regulation. Converging results remain encouraging given this population's difficulties coping with adversity, managing emotions and interacting socially which strongly influence developmental outcomes.

    Universal screening for depression during pregnancy and postpartum is recommended, yet mental health treatment and follow-up rates among screen-positive women in rural settings are low. We studied the feasibility, acceptability and effectiveness of perinatal depression treatment integrated into a rural obstetric setting. We conducted an open treatment study of a screening and intervention program modified from the Depression Attention for Women Now (DAWN) Collaborative Care model in a rural obstetric clinic. Depression screen-positive pregnant and postpartum women received problem-solving therapy (PST) with or without antidepressants. A care manager coordinated communication between patient, obstetrician and psychiatric consultant. We measured change in the Patient Health Questionnaire 9 (PHQ-9) score. We used surveys and focus groups to measure patient and provider satisfaction and analyzed focus groups using qualitative analysis. The intervention was well accepted by providers and patients, based on survey and focus group data. Feasibility was also evidenced by recruitment (87.1%) and retention (92.6%) rates and depression outcomes (64% with >50% improvement in PHQ 9) which were comparable to clinical trials in similar urban populations. Conclusions for practice: DAWN Collaborative Care modified for treatment of perinatal depression in a rural obstetric setting is feasible and acceptable. Behavioral health services integrated into rural obstetric settings could improve care for perinatal depression.

    The current editorial study focuses on the idea of using advanced imaging methods in order to better classify and treat patients with depression and other psychiatric illnesses. The editorial is based on the review of Heymann and Bonne, published in this issue of the journal, showing differences between bi-polar and uni-polar depression using functional neuroimaging methods. This example, although not applicable yet in clinical practice, is the basis for future advances in psychiatric classification, together with clinical subtyping, and more biological markers, including genetic profiling.

    Full Text Available This paper (1 reviews the physical and religious barriers to CBT that disabled medically ill-depressed patients face, (2 discusses research on the relationship between religion and depression-induced physiological changes, (3 describes an ongoing randomized clinical trial of religious versus secular CBT in chronically ill patients with mild-to-moderate major depression designed to (a overcome physical and religious barriers to CBT and (b compare the efficacy of religious versus secular CBT in relieving depression and improving immune and endocrine functions, and (4 presents preliminary results that illustrate the technical difficulties that have been encountered in implementing this trial. CBT is being delivered remotely via instant messaging, telephone, or Skype, and Christian, Jewish, Muslim, Buddhist, and Hindu versions of religious CBT are being developed. The preliminary results described here are particular to the technologies employed in this study and are not results from the CBT clinical trial whose findings will be published in the future after the study ends and data are analyzed. The ultimate goal is to determine if a psychotherapy delivered remotely that integrates patients’ religious resources improves depression more quickly than a therapy that ignores them, and whether religious CBT is more effective than conventional CBT in reversing depression-induced physiological changes.

  6. [Recited depression].

    Several subjects who tell their depression and play a part of it in front of the doctor without being really depressed are reported. Some of them try to hide the symptoms (irritability or erethism, ceremonials of obsessive neurosis, shunning of phobia) which, in their opinion, might be detrimental to their reputation. Others neglect to describe some of the symptoms of their polymorphous clinical picture only underlining the depressive signs. Some others play a part of depression because they have believed to recognize themselves in persons presented by mass media, because it seems to them a duty to show an adequate depression in case of mournful event, or because they "convert" their problem into a depression. Some others use depression as a blackmail, or to obtain an advantage from doctor's conviction about their illness. The reason for the high frequency of similar cases in the present time are examined: the scientific divulgation and the acceptance of depression by the modern society are among the most important ones. The peculiar semantic vicissitudes of the word depression are also reviewed. A widening of the boundaries of depression has contributed to an increase in the number of the cases. Finally, in addition to patients who are depressed without being aware of it, the authors focus the inverse possibility: patients who believed or try to make their doctor believe (playing the part of depression in front of them) that they are depressed.

    A recent criticism of social epidemiological studies, and multi-level studies in particular has been a paucity of theory. We will present here the protocol for a study that aims to build a theory of the social epidemiology of maternal depression. We use a critical realist approach which is trans-disciplinary, encompassing both quantitative and qualitative traditions, and that assumes both ontological and hierarchical stratification of reality. We describe a critical realist Explanatory Theory Building Method comprising of an: 1) emergent phase, 2) construction phase, and 3) confirmatory phase. A concurrent triangulated mixed method multilevel cross-sectional study design is described. The Emergent Phase uses: interviews, focus groups, exploratory data analysis, exploratory factor analysis, regression, and multilevel Bayesian spatial data analysis to detect and describe phenomena. Abductive and retroductive reasoning will be applied to: categorical principal component analysis, exploratory factor analysis, regression, coding of concepts and categories, constant comparative analysis, drawing of conceptual networks, and situational analysis to generate theoretical concepts. The Theory Construction Phase will include: 1) defining stratified levels; 2) analytic resolution; 3) abductive reasoning; 4) comparative analysis (triangulation); 5) retroduction; 6) postulate and proposition development; 7) comparison and assessment of theories; and 8) conceptual frameworks and model development. The strength of the critical realist methodology described is the extent to which this paradigm is able to support the epistemological, ontological, axiological, methodological and rhetorical positions of both quantitative and qualitative research in the field of social epidemiology. The extensive multilevel Bayesian studies, intensive qualitative studies, latent variable theory, abductive triangulation, and Inference to Best Explanation provide a strong foundation for Theory

    To validate the usefulness of the packages available for automated hippocampal volumetry, we measured hippocampal volumes using one manual and two recently developed automated volumetric methods. The study included T1-weighted magnetic resonance imaging (MRI) of 21 patients with chronic major depressive disorder (MDD) and 20 normal controls. Using coronal turbo field echo (TFE) MRI with a slice thickness of 1.3 mm, the hippocampal volumes were measured using three methods: manual volumetry, surface-based parcellation using FreeSurfer, and individual atlas-based volumetry using IBASPM. In addition, the intracranial cavity volume (ICV) was measured manually. The absolute left hippocampal volume of the patients with MDD measured using all three methods was significantly smaller than the left hippocampal volume of the normal controls (manual P=0.029, FreeSurfer P=0.035, IBASPM P=0.018). After controlling for the ICV, except for the right hippocampal volume measured using FreeSurfer, both measured hippocampal volumes of the patients with MDD were significantly smaller than the measured hippocampal volumes of the normal controls (right manual P=0.019, IBASPM P=0.012; left manual P=0.003, FreeSurfer P=0.010, IBASPM P=0.002). In the intrarater reliability test, the intraclass correlation coefficients (ICCs) were all excellent (manual right 0.947, left 0.934; FreeSurfer right 1.000, left 1.000; IBASPM right 1.000, left 1.000). In the test of agreement between the volumetric methods, the ICCs were right 0.846 and left 0.848 (manual and FreeSurfer), and right 0.654 and left 0.717 (manual and IBASPM). The automated hippocampal volumetric methods showed good agreement with manual hippocampal volumetry, but the volume measured using FreeSurfer was 35% larger and the agreement was questionable with IBASPM. Although the automated methods could detect hippocampal atrophy in the patients with MDD, the results indicate that manual hippocampal volumetry is still the gold standard

    Intervention studies have found that psychotherapeutic interventions that explicitly integrate clients’ spiritual and religious beliefs in therapy are as effective, if not more so, in reducing depression than those that do not for religious clients. However, few empirical studies have examined the effectiveness of religiously (vs. spiritually) integrated psychotherapy, and no manualized mental health intervention had been developed for the medically ill with religious beliefs. To address this gap, we developed and implemented a novel religiously integrated adaptation of cognitive–behavioral therapy (CBT) for the treatment of depression in individuals with chronic medical illness. This article describes the development and implementation of the intervention. First, we provide a brief overview of CBT. Next, we describe how religious beliefs and behaviors can be integrated into a CBT framework. Finally, we describe Religiously Integrated Cognitive Behavioral Therapy (RCBT), a manualized therapeutic approach designed to assist depressed individuals to develop depression-reducing thoughts and behaviors informed by their own religious beliefs, practices, and resources. This treatment approach has been developed for 5 major world religions (Christianity, Judaism, Islam, Buddhism, and Hinduism), increasing its potential to aid the depressed medically ill from a variety of religious backgrounds.

    Problems with lowering of water table are common all over the world. Intensive pumping of water from aquifers for consumption, irrigation, industrial or mining purposes often causes groundwater depletion and results in the formation of cone of depression. This can severely decrease water pressure, even over vast areas, and can create severe problems such as degradation of agriculture or natural environment sometimes depriving people and animals of water supply. In this paper, the authors present a method for determining the area of influence of a groundwater depression cone resulting from prolonged drainage, by means of satellite images in optical, near infrared and thermal infrared bands from TM sensor (Thematic Mapper) and ETM+ sensor (Enhanced Thematic Mapper +) placed on Landsat 5 and Landsat 7 satellites. The research area was Szczercowska Valley (Pol. Kotlina Szczercowska), Central Poland, located within a range of influence of a groundwater drainage system of the lignite coal mine in Belchatow. It is the biggest lignite coal mine in Poland and one of the largest in Europe exerting an enormous impact on the environment. The main method of satellite data analysis for determining soil moisture, was the so-called triangle method. This method, based on TVDI (Temperature Vegetation Dryness Index) was supported by additional spatial analysis including ordinary kriging used in order to combine fragmentary information obtained from areas covered by meadows. The results obtained are encouraging and confirm the usefulness of the triangle method not only for soil moisture determination but also for assessment of the temporal and spatial changes in the area influenced by the groundwater depression cone. The range of impact of the groundwater depression cone determined by means of above-described remote sensing analysis shows good agreement with that determined by ground measurements. The developed satellite method is much faster and cheaper than in-situ measurements

    Full Text Available Abstract Background Depression in later life is a common mental disorder with a prevalence rate of between 3% and 35% for minor depression and approximately 2% for Major Depressive Disorder (MDD. The most common treatment modalities for MDD are antidepressant medication and psychological interventions. Recently, Behavioral Activation (BA has gained renewed attention as an effective treatment modality in MDD. Although BA is considered an easy accessible intervention for both patients and health care workers (such as nurses, there is no research on the effectiveness of the intervention in inpatient depressed elderly. The aim of study, described in the present proposal, is to examine the effects of BA when executed by nurses in an inpatient population of elderly persons with MDD. Methods/design The study is designed as a multi-center cluster randomized controlled trial. BA, described as The Systematic Activation Method (SAM will be compared with Treatment as Usual (TAU. We aim to include ten mental health care units in the Netherlands that will each participate as a control unit or an experimental unit. The patients will meet the following criteria: (1 a primary diagnosis of Major Depressive Disorder (MDD according to the DSM-IV criteria; (2 60 years or older; (3 able to read and write in Dutch; (4 have consented to participate via the informed consent procedure. Based on an effect size d = 0.7, we intend to include 51 participants per condition (n = 102. The SAM will be implemented within the experimental units as an adjunctive therapy to Treatment As Usual (TAU. All patients will be assessed at baseline, after eight weeks, and after six months. The primary outcome will be the level of depression measured by means of the Beck Depression Inventory (Dutch version. Other assessments will be activity level, mastery, costs, anxiety and quality of life. Discussion To our knowledge this is the first study to test the effect of Behavioral

    The logging evaluation of tuffaceous sandstone reservoirs is always a difficult problem. Experiments show that the tuff and shale have different logging responses. Since the tuff content exerts an influence on the computation of shale content and the parameters of the reservoir, and the accuracy of saturation evaluation is reduced. Therefore, the effect of tuff on the calculation of saturation cannot be ignored. This study takes the tuffaceous sandstone reservoirs in the X depression of Hailar-Tamtsag basin as an example to analyze. And the electric conduction model of tuffaceous sandstone reservoirs is established. The method which combines bacterial foraging algorithm and particle swarm optimization algorithm is used to calculate the content of reservoir components in well logging for the first time, and the calculated content of tuff and shale corresponds to the results analysis of thin sections. The experiment on cation exchange capacity (CEC) proves that tuff has conductivity, and the conversion relationship between CEC and resistivity proposed by Toshinobu Iton has been improved. According to the rock electric experiment under simulated reservoir conditions, the rock-electro parameters (a, b, m and n) are determined. The improved relationship between CEC and resistivity and the rock-electro parameters are used in the calculation of saturation. Formula (1) shows the saturation equation of the tuffaceous reservoirs:According to the comparative analysis between irreducible water saturation and the calculated saturation, we find that the saturation equation used CEC data and rock-electro parameters has a better application effect at oil layer than Archie's formulas.

    Objective Depression affects one in four adults with type 2 diabetes (T2DM) and is associated with worsened diabetes complications, increased health care costs and early mortality. Rural and low-income urban areas, including the Appalachian region, represent an epicenter of the T2DM epidemic. Program ACTIVE II is a comparative effectiveness treatment trial designed to test whether a combination of cognitive behavioral therapy (CBT) and community-based exercise (EXER) will offer greater improvements in diabetes and depression outcomes compared to individual treatment approaches and usual care (UC). The secondary aims are to assess changes in cardiovascular risk factors across groups and to conduct a cost-effectiveness analysis of predicted incidence of cardiovascular complications across groups. Methods The study is a 2-by-2 factorial randomized controlled trial consisting of 4 treatment groups: CBT alone, EXER alone, combination of CBT and EXER, and UC. Adults with T2DM for > 1 year and who meet DSM-IVTR criteria for Major Depressive Disorder (MDD) are eligible to participate at two rural Appalachian sites (southeastern Ohio and West Virginia) and one urban site (Indianapolis). This type II behavioral translation study uses a community-engaged research (CEnR) approach by incorporating community fitness centers and mental health practices as interventionists. Conclusions This is the first study to evaluate the comparative effectiveness of combined CBT and exercise in the treatment of depression using community-based intervention delivery. This approach may serve as a national model for expanding depression treatment for patients with T2DM. PMID:27500279

    Full Text Available : BACKGROUND: The presence of depression in schizophrenia has been recognized since the time of Kraepelin and Bleuler. Depressive symptoms associated with schizophrenia have received considerable attention in recent years. It has been suggested that patient may manifest depressive symptoms during the onset of psychotic symptoms, during course of chronic schizophrenia or after the psychotic symptoms has been abated. AIMS & OBJECTIVES: 1. To study the prevalence of depression in schizophrenia. 2. To study the correlation between depression and subtype of schizophrenia. MATERALS & METHODS: 50 consecutive patients suffering from schizophrenia according to DSM-IV criteria, who were brought to psychiatric OPD were selected for this study. Patients between 15-55years age were included in this study. HDRS (Hamilton depression rating scale was administered to all patients to assess severity of depression. RESULTS: Out of 50 patients suffering from schizophrenia, 44% of patients suffering from schizophrenia were depressed. In this study the most common symptoms of depression were depressed mood, loss of interest on pleasure, sleep disturbance, loss of energy/fatigue, psychomotor disturbance, suicidal thought or death wish, feeling of hopelessness. CONCLUSION: Depression is common in patients suffering from schizophrenia. The severity of depression was mild to moderate, no one had severe depression. It is more common in patients who are living in nuclear family, who are divorced, who have paranoid type of schizophrenia, who were not on antipsychotic medicine.

    The authors present arguments in favour of the necessity to reveal and treat the co-morbid conditions with special reference to depressive disorders in the patients during the early rehabilitation period following preceding ischemic stroke. They demonstrate the importance of the application of non-medicamentous therapy in combination with the standard medicamental treatment. Special emphasis is placed on the analysis of the data obtained during evaluation of the effectiveness of combined therapy with the use of the enhanced external counterpulsation method in the early post-stroke period. It is concluded that the early diagnostics and timely correction of anxio-depressive conditions promotes the efficiency of rehabilitative measures and improves the quality of life of the patients with such disorders.

    Full Text Available Abstract Background Given that the prevalence of antenatal and postnatal depression is high, with estimates around 13%, and the consequences serious, efforts have been made to identify risk factors to assist in prevention, identification and treatment. Most risk factors associated with postnatal depression have been well researched, whereas predictors of antenatal depression have been less researched. Risk factors associated with early parenting stress have not been widely researched, despite the strong link with depression. The aim of this study was to further elucidate which of some previously identified risk factors are most predictive of three outcome measures: antenatal depression, postnatal depression and parenting stress and to examine the relationship between them. Methods Primipara and multiparae women were recruited antenatally from two major hoitals as part of the beyondblue National Postnatal Depression Program 1. In this subsidiary study, 367 women completed an additional large battery of validated questionnaires to identify risk factors in the antenatal period at 26–32 weeks gestation. A subsample of these women (N = 161 also completed questionnaires at 10–12 weeks postnatally. Depression level was measured by the Beck Depression Inventory (BDI. Results Regression analyses identified significant risk factors for the three outcome measures. (1. Significant predictors for antenatal depression: low self-esteem, antenatal anxiety, low social support, negative cognitive style, major life events, low income and history of abuse. (2. Significant predictors for postnatal depression: antenatal depression and a history of depression while also controlling for concurrent parenting stress, which was a significant variable. Antenatal depression was identified as a mediator between seven of the risk factors and postnatal depression. (3. Postnatal depression was the only significant predictor for parenting stress and also acted as a mediator

    The number of elderly patients with depression has steadily increased in recent years; therefore, new treatment options and therapy approaches are urgently needed to improve treatment in this patient group. The aim of this project was to evaluate the additional application of auricular acupuncture according to the NADA protocol in patients treated in a daytime ward in terms of acceptability and feasibility. A total of 20 psychogeriatric patients from a daytime clinic suffering from major depression (ICD-10: F32-F33) received auricular acupuncture in addition to the standard treatment three times per week over a treatment course of 3 weeks. Semi-structured interviews were conducted with the participants and the therapeutic team and qualitative content analyses were carried out. Depression, cognition, quality of sleep and quality of life were assessed using validated quantitative instruments. There was a 95 % utilization of the therapy. The qualitative analysis showed a high acceptance by all participants. The dominant perception by the patients was a positive expectation and conviction that acupuncture was an effective form of therapy without side effects, which could contribute to recovery. The majority of patients also felt that there was an improvement in the symptoms. The quantitative analysis revealed significant improvements in the target parameters. The acceptance of the intervention by the patients and the willingness of the interdisciplinary team underlines the feasibility of this implementation within a fixed therapeutic concept. The significant pre-post improvements indicated a potential benefit and should be verified in further efficacy studies.

    2012-03-01

    Full Text Available Abstract Background People with mental illness are more likely to suffer physical health problems than comparable populations who do not have mental illness. There is evidence to suggest that exercise, as well has having obvious physical benefits, also has positive effects on mental health. There is a distinct paucity of research testing its effects on young people seeking help for mental health issues. Additionally, it is generally found that compliance with prescribed exercise programmes is low. As such, encouraging young people to exercise at levels recommended by national guidelines may be unrealistic considering their struggle with mental health difficulties. It is proposed that an exercise intervention tailored to young people's preferred intensity may improve mental health outcomes, overall quality of life, and reduce exercise attrition rates. Methods/Design A sequential mixed methods design will be utilised to assess the effectiveness of an individually tailored exercise programme on the mental health outcomes of young people with depression. The mixed methods design incorporates a Randomised Controlled Trial (RCT, focus groups and interviews and an economic evaluation. Participants: 158 young people (14-17 years recruited from primary care and voluntary services randomly allocated to either the intervention group or control group. Intervention group: Participants will undertake a 12 week exercise programme of 12 × 60 minutes of preferred intensity aerobic exercise receiving motivational coaching and support throughout. Participants will also be invited to attend focus groups and 1-1 interviews following completion of the exercise programme to illicit potential barriers facilitators to participation. Control group: Participants will receive treatment as usual. Primary Outcome measure: Depression using the Children's Depression Inventory 2 (CDI-2. Secondary Outcome measures: Quality of Life (EQ-5D, physical fitness (Borg RPE scale, heart

    2016-11-01

    Full Text Available Background and Objectives: Heart rate variability (HRV has been intensively studied as a promising biological marker of major depressive disorder (MDD. Our previous study confirmed that autonomic activity and reactivity in depression revealed by HRV during rest and mental task (MT conditions can be used as diagnostic measures and in clinical evaluation. In this study, logistic regression analysis (LRA was utilized for the classification and prediction of MDD based on HRV data obtained in an MT paradigm.Methods: Power spectral analysis of HRV on R-R intervals before, during, and after an MT (random number generation was performed in 44 drug-naïve patients with MDD and 47 healthy control subjects at Department of Psychiatry in Shizuoka Saiseikai General Hospital. Logit scores of LRA determined by HRV indices and heart rates discriminated patients with MDD from healthy subjects. The high frequency (HF component of HRV and the ratio of the low frequency (LF component to the HF component (LF/HF correspond to parasympathetic and sympathovagal balance, respectively.Results: The LRA achieved a sensitivity and specificity of 80.0% and 79.0%, respectively, at an optimum cutoff logit score (0.28. Misclassifications occurred only when the logit score was close to the cutoff score. Logit scores also correlated significantly with subjective self-rating depression scale scores (p < 0.05.Conclusion: HRV indices recorded during a mental task may be an objective tool for screening patients with MDD in psychiatric practice. The proposed method appears promising for not only objective and rapid MDD screening, but also evaluation of its severity.

    Objective. Arguing that additional symptoms should be added to the criteria for atypical depression. Method. Published research articles on atypical depression are reviewed. Results. (1) The original studies upon which the criteria for atypical depression were based cited fatigue, insomnia, pain, and loss of weight as characteristic symptoms. (2) Several studies of DSM depressive criteria found patients with atypical depression to exhibit high levels of insomnia, fatigue, and loss of appetite/weight. (3) Several studies have found atypical depression to be comorbid with headaches, bulimia, and body image issues. (4) Most probands who report atypical depression meet criteria for "somatic depression," defined as depression associated with several of disordered eating, poor body image, headaches, fatigue, and insomnia. The gender difference in prevalence of atypical depression results from its overlap with somatic depression. Somatic depression is associated with psychosocial measures related to gender, linking it with the descriptions of atypical depression as "reactive" appearing in the studies upon which the original criteria for atypical depression were based. Conclusion. Insomnia, disordered eating, poor body image, and aches/pains should be added as criteria for atypical depression matching criteria for somatic depression defining a reactive depressive disorder possibly distinct from endogenous melancholic depression.

    During the last decade online interventions have emerged as a promising approach for patients with mild/moderate depressive symptoms, reaching at large populations and representing cost-effective alternatives. The main objective of this double-blind, randomized controlled trial is to examine the efficacy of an internet-based self-management tool (iFightDepression) for mild to moderate depression as an add-on to treatment as usual (TAU) versus internet-based psychoeducation plus TAU. A total of 310 participants with major depression disorder (MDD) will be recruited at four different mental-health facilities in Spain. Participants will be randomly allocated to one of two study arms: iFightDepression (iFD) tool + TAU vs. internet-based psychoeducation + TAU. Both interventions last for 8 weeks and there is a 12 weeks follow up. The primary outcome measure is changes in depressive symptoms assessed with the Hamilton Depression Rating Scale. Additionally, pre-post interventions assessments will include socio-demographic data, a brief medical and clinical history and self-reported measures of depressive symptoms, quality of life, functional impairments and satisfaction with the iFD tool. iFightDepression is an easy-prescribed tool that could increase the efficacy of conventional treatment and potentially reach untreated patients, shortening waiting lists to receive psychological treatment. Confirming the efficacy of the iFD internet-based self-management tool as an add-on treatment for individuals with mild to moderate depression will be clinically-relevant.

    Background: In three academic articles, this PhD thesis investigates maternal postpartum depression (PPD) as a risk factor for the infant-mother attachment and infant development. Previous studies have been contradictory with respect to the question of whether PPD can have long term effects...... on offspring. This may be due to not differing between when PPD is only occurring in the postpartum period and when effects are also due to ongoing or recurrent depression. However, it may also be due to viewing maternal depression as a unitary construct, and not considering underlying maternal psychological...... difficulties which may moderate potential adverse effects. The present thesis investigates two potential maternal moderators of risk:. Comorbid personality disorder and adult attachment insecurity. Moreover, the question of early environmental effects of PPD versus effects of later or ongoing depression...

    Purpose Despite its clinical importance, adolescent subthreshold depression remains a largely neglected topic. The aims of this study were to accurately identify the natural course of depressive symptoms and the risk for developing major depressive episode (MDE) in late adolescents with subthreshold depression over 1 year. Patients and methods One hundred and seventy-two participants <20 years of age (mean age: 18.32 years, standard deviation: 0.50), who did not meet the full criteria for an MDE, were selected from 2,494 screened freshmen based on the Beck Depression Inventory, 2nd edition (BDI-II). We conducted a cohort study of three groups (low-, middle-, and high-symptom groups) divided based on BDI-II scores, over a 1 year period with the use of bimonthly assessments. Temporal changes of depressive symptoms were analyzed using linear mixed modeling and growth mixture modeling. Results First, we found that late adolescents with subthreshold depression (high depressive symptoms) were split between the increasing and decreasing depressive symptoms groups, whereas the majority of the less-symptoms group remained stable during 1 year. Second, in comparison with late adolescents with less depressive symptoms, those with subthreshold depression had an elevated risk of later depression. Conclusion Some late adolescents with subthreshold depression had increased depressive symptoms and developed an MDE during 1 year. Therefore, it is necessary for us to rigorously assess the changes in subthreshold depressive symptoms over time in late adolescents. PMID:28053534

    2015-06-01

    Full Text Available Background and Objectives: Apathy is a behavioral syndrome that often co-occurs with depression. Nonetheless, the etiology of apathy and depression may be different. We hypothesized that apathy occurs more often in depressed compared to non-depressed older persons; and that independent correlates for apathy will be different in depressed and non-depressed older persons. Methods: In this cross-sectional study of Netherlands Study of Depression in Older Persons (NESDO, a total of 350 depressed older persons according to the Composite International Diagnostic Interview (CIDI and 126 non-depressed older persons, aged at least 60 years were recruited in several Medical Centres and general practices. In both depressed and non-depressed older persons, those with and without apathy as assessed with the Apathy Scale (score ≥ 14 were compared with regard to socio-demographic, clinical, and biological characteristics. Results: Apathy was present in 75% of the depressed and 25% of the non- depressed older persons. Independent correlates of apathy in both depressed and non-depressed older persons were male gender and less education. Furthermore, in depressed older persons, higher scores on the Inventory of Depressive Symptomatology (IDS and, in non-depressed older persons, a higher C-reactive protein (CRP level correlated independently with apathy. Conclusions: Apathy occurred frequently among both depressed and non-depressed older persons. Among depressed older persons, apathy appeared to be a symptom of more serious depression, whereas among non-depressed persons apathy was associated with increased CRP being a marker for immune activation, suggesting a different aetiology for apathy in its own right.

    2015-01-01

    Full Text Available Multiple models of human neuropsychiatric pathologies have been generated during the last decades which frequently use chronic dosing. Unfortunately, some drug administration methods may result in undesirable effects creating analysis confounds hampering model validity and preclinical assay outcomes. Here, automated analysis of floating behaviour, a sign of a depressive-like state, revealed that mice, subjected to a three-week intraperitoneal injection regimen, had increased floating. In order to probe an alternative dosing design that would preclude this effect, we studied the efficacy of a low dose of the antidepressant imipramine (7 mg/kg/day delivered via food pellets. Antidepressant action for this treatment was found while no other behavioural effects were observed. We further investigated the potential efficacy of chronic dosing via food pellets by testing the antidepressant activity of new drug candidates, celecoxib (30 mg/kg/day and dicholine succinate (50 mg/kg/day, against standard antidepressants, imipramine (7 mg/kg/day and citalopram (15 mg/kg/day, utilizing the forced swim and tail suspension tests. Antidepressant effects of these compounds were found in both assays. Thus, chronic dosing via food pellets is efficacious in small rodents, even with a low drug dose design, and can prevail against potential confounds in translational research within depression models applicable to adverse chronic invasive pharmacotherapies.

    The geology and hydrogeology of the Liptovská Kotlina Depression were studied by means of new geophysical methods. Controlled source audio-frequency magnetotellurics enabled us to delineate the relief of the pre-Cainozoic basement in the western part of the Liptovská Kotlina Depression into two segments with different lithostratigraphic units. Our complex findings disprove the interconnection between the Bešeňová and Lúčky water bearing structures located in the study area. The results were interpreted in the form of a resistivity cross section and resistivity model. The geological interpretation of the obtained results, taking into account the other geophysical and geological constrains showed that the pre-Cainozoic basement has a tectonically disrupted, broken relief. The Bešeňová and Lúčky structures appear to be isolated by the Palaeogene sediments (sandstone, claystone) and in the deeper part also by marly carbonates and marlstones of the Jurassic age belonging to the Fatricum. It was confirmed that the structural connectivity of geothermal aquifers in the area between the Bešeňová and Lúčky-Kaľameny should not exist. The assumption of different circulation depth was also confirmed by geothermometry and existing radiocarbon analyses applied on groundwater in both areas.

    The thesis aims to answer the questions about the profile of mental ability in endogenous depression and to decide whether self-estimation of depressive symptoms influences the results achieved by patients in memory tests. Fifty six patients suffering from endogenous depression have been examined. The following methods have been applied: Mini Mental State Examination, Benton Visual Retention Test, Beck Depression Inventory, hold tests: Vocabulary, Information, Comprehension and Digit Span of Wechsler Adult Intelligence Scale (WAIS), Rey-Osterrieth Complex Figure, Auditory Verbal Learning Test, DCS Weidlich. General status of cognitive functions correlates with the profile of specific kinds of memory results, particularly with delayed memory. Self-estimation of depressive symptoms intensity is mostly influenced by memory capacity, visuomotorial factor, functions of perception and lingual factor. High correlation between verbal and non verbal learning shows uniform influence of depression on the process of learning.

    Antiretroviral therapy (ART) is known for its side effects. In this paper, we describe ART side effects as experienced by Chinese HIV+ individuals. This study presents two stages of a research project, combining qualitative in-depth interviews (29 HIV+ participants) with quantitative statistical data analysis (N = 120). All data was collected between July 2005 to March 2008 at Beijing's Ditan Hospital. Consent was obtained from each participant for the qualitative interview and again for the quantitative survey. During in-depth interviews, Chinese HIV+ patients reported experiencing digestive discomfort, skin rashes, numbness, memory loss, nightmares, and dizziness, which not only brought them physical discomfort, but also interrupted different dimensions of their social lives. Furthermore, multiple regression analyses revealed that those who reported more severe side effects also experienced greater depressive mood after controlling for other clinical and psychosocial factors. ART side effects are one of the primary reasons causing HIV+ individuals to delay or stop taking life-saving medication; therefore, clinical interventions are critically needed to assist HIV+ individuals in managing ART side effects. ART side effects reinforced existing negative attitudes toward ART and lead to lower ART adherence. Future research should focus on developing culturally sensitive interventions to enhance HIV+ self-management, to alleviate physical and psychological burden from ART and HIV.

    The efficiency of the therapy of psychiatric diseases is estimated using the fluorescence measurements of the conformational changes of human serum albumin in the course of medical treatment. The fluorescence decay curves of the CAPIDAN probe (N-carboxyphenylimide of the dimethylaminonaphthalic acid) in the blood serum are measured. The probe is specifically bound to the albumin drug binding sites and exhibits fluorescence as a reporter ligand. A variation in the conformation of the albumin molecule substantially affects the CAPIDAN fluorescence decay curve on the subnanosecond time scale. A subnanosecond pulsed laser or a Pico-Quant LED excitation source and a fast photon detector with a time resolution of about 50 ps are used for the kinetic measurements. The blood sera of ten patients suffering from depression and treated at the Institute of Psychiatry were preliminary clinically tested. Blood for analysis was taken from each patient prior to the treatment and on the third week of treatment. For ten patients, the analysis of the fluorescence decay curves of the probe in the blood serum using the three-exponential fitting shows that the difference between the amplitudes of the decay function corresponding to the long-lived (9 ns) fluorescence of the probe prior to and after the therapeutic procedure reliably differs from zero at a significance level of 1% ( p < 0.01).

    The field of psychoneuroimmunology (PNI) aims to uncover the processes and consequences of nervous, immune, and endocrine system relationships. Behavior is a consequence of such interactions and manifests from a complex interweave of factors including immune-to-neural and neural-to-immune communication. Often the signaling molecules involved during a particular episode of neuroimmune activation are not known but behavioral response provides evidence that bioactives such as neurotransmitters and cytokines are perturbed. Immunobehavioral phenotyping is a first-line approach when examining the neuroimmune system and its reaction to immune stimulation or suppression. Behavioral response is significantly more sensitive than direct measurement of a single specific bioactive and can quickly and efficiently rule in or out relevance of a particular immune challenge or therapeutic to neuroimmunity. Classically, immunobehavioral research was focused on sickness symptoms related to bacterial infection but neuroimmune activation is now a recognized complication of diseases and disorders ranging from cancer to diabesity. Immunobehaviors include lethargy, loss of appetite, and disinterest in social activity and the surrounding environment. In addition, neuroimmune activation can precipitate feelings of depression and anxiety while negatively impacting cognitive function and physical activity. Provided is a detailed overview of behavioral tests frequently used to examine neuroimmune activation in mice with a special emphasis on preexperimental conditions that can confound or prevent successful immunobehavioral experimentation.

    In this study, an attempt has been made to develop a simple multiple regression model to forecast the total number of depressions and cyclones (TNDC) over Bay of Bengal during summer monsoon (June-September) season using the data for the period, 1995-2016. Four potential predictors (zonal wind speed at 850 hPa in May and April SST in the North Australia-Indonesia region, 05°S-15°S; 120°E-160°E; March NINO 3.4 SST and geopotential height at 200 hPa in the region, 0°N-10°N; 80°E-100°E) have been identified to forecast TNDC. A remarkably high multiple correlation coefficient of 0.92 has been observed with the TNDC which explains 85% variability. The methodology has been tested for the recent 5 years (2012-2016) and found a good agreement between the observed and forecast values of TNDC except in 2015 in which the observed and predicted TNDC were 2 and 0, respectively. It is interesting to see high and significant correlations between the above predictors and the genesis potential parameter (GPP) during summer monsoon season. This GPP depends on the relative vorticity at 850 hPa, mid troposphere relative humidity, thermal instability between 850 and 500 hPa, and vertical wind shear between 200 and 850 hPa. It is inferred that the above predictors are influencing the environmental conditions over Bay of Bengal which, in turn, influencing the genesis of cyclones during summer monsoon season. The impact of ENSO (El-Nino-Southern Oscillation) and La-Nina in TNDC is examined and found that the vertical wind shear and relative vorticity are high and the GPP was almost double in ENSO compared with that in La-Nina which favoured high (low) TNDC under ENSO (La-Nina).

    We study the appearance, development and depression of the alpha-rhythm in human EEG data during a psychophysiological experiment by stimulating cognitive activity with the perception of ambiguous object. The new method based on continuous wavelet transform allows to estimate the energy contribution of various components, including the alpha rhythm, in the general dynamics of the electrical activity of the projections of various areas of the brain. The decision-making process by observe ambiguous images is characterized by specific oscillatory alfa-rhytm patterns in the multi-channel EEG data. We have shown the repeatability of detected principles of the alpha-rhythm evolution in a data of group of 12 healthy male volunteers.

  17. Metacognition and depressive realism: evidence for the level-of-depression account.

    Soderstrom, Nicholas C; Davalos, Deana B; Vázquez, Susana M

    2011-09-01

    Introduction. The present study examined the relationship between metacognition (i.e., "thinking about thinking") and depression. More specifically, the depressive realism hypothesis (Alloy & Abramson, 1979), which posits that depressed people have a more accurate view of reality than nondepressed people, was tested. Methods. Nondepressed, mildly depressed, and moderately depressed individuals predicted their memory performance by making judgements of learning after each studied item. These predictions were then compared with actual performance on a free recall task to assess calibration, an index of metacognitive accuracy. Results and conclusions. Consistent with the depressive realism hypothesis, mild depression was associated with better calibration than nondepression. However, this "sadder but wiser" phenomenon appears to only exist to point, as moderate depression and nondepression showed no calibration differences. Thus, the level-of-depression account of depressive realism is supported.

    The impact of living with metastatic breast cancer (MBC) is considerable and psychosocial support can be beneficial. Mindfulness-based stress reduction (MBSR) can help self-management of anxiety, depression, quality of life (QoL), and fatigue and has been evaluated in early-stage breast cancer but not MBC. This study investigated the acceptability and feasibility of providing MBSR for women with MBC and of introducing MBSR into a National Health Service (NHS) setting. A mixed methods convergent design was used. Eligible women with MBC, an Eastern Cooperative Oncology Group (ECOG) score of 0 to 2, stable disease, and life expectancy of at least 6 months were invited to attend (by their oncologist) an 8-week MBSR course. Qualitative interviews with patients, a focus group, and interview with NHS staff were held to explore acceptability and feasibility of MBSR. Questionnaires at baseline, during (weeks 4, 8), and after (weeks 16, 24) the course measured fatigue, anxiety and depression, mindfulness, disease-specific QoL, and generic preference based QoL. Of 100 women approached, 20 joined the study. One woman dropped out prior to the intervention due to illness progression. Nineteen women took part in 3 MBSR courses. Recruitment to 2 of the 3 courses was slow. Commitment to 8 weeks was a reason for non-participation, and proved challenging to participants during the course. Participants found the course acceptable and reported many cumulative and ongoing benefits. These included feeling less reactive to emotional distress and more accepting of the disruption to life that occurs with living with MBC. There was high attendance, completion of course sessions, adherence to home practice, excellent follow-up rates, and high questionnaire return rates. MBSR was acceptable to MBC patients, who perceived benefits such as improved anxiety and QoL; but the MBSR course requires a considerable time commitment. There is scope to tailor the intervention so that it is less intensive.

Methods: Two hundred and thirty one cases of PSD were randomly divided into two groups, acupuncture and control groups. In acupuncture group, Baihui (百会 GV 20), Dazhui (大椎 GV 14), Neiguan (内关 PC 6), Taichong (太冲 LR 3) and Shenmen (神门 HT 7) were selected as the main points to invigorate flow of qi in the Du Meridian and clear the mind. Patients in the control group received Fluoxetine orally, 20 rng once per-day. In addition, the same routine treatments were given to both groups, strengthened with rehabilitation exercises as early as possible; 8 weeks constituted one therapeutic course. HAMD and severity of neuro-functional defect of each case were evaluated before and 8-week after the treatment. Results: The total effective rate of acupuncture group was 92.37%, the control group, 72.88%. According to x2 test, the difference between the two groups was remarkably significant (P<0.05). Conclusion: Acupuncture therapy of activating the Du Meridian and clearing the mind in the treatment of PSD was safe and effective.

    Cultural variations in the perception of depression make it difficult to recognize the disorder resulting in older Hispanics not being diagnosed and not receiving appropriate treatment. This study used a mixed-method design to explore older Hispanics' explanatory model of depression. Depression was recognized as the result of life stressors and personal weaknesses. Terms used for depressed people included "crazy, worry, bored, and nerves." These culturally coded terms may confound diagnosis among many Hispanics who find depression a shameful condition. Findings can be used to inform the adaptation of culturally relevant approaches to better serve the Hispanic community in this country.

    Full Text Available OBJECTIVE: To evaluate the comorbidity of depressive disorders in patients with refractory temporal lobe epilepsy (TLE. METHOD: We evaluated 25 consecutive patients with refractory TLE (16 women and 9 men, using semi-structured psychiatric interviews, according to the International Classification of Diseases (ICD-10, and the Beck Depression Inventory. RESULTS: Seventeen of 25 patients (68% had depressive disorder: 6 with dysthymia, three with major depressive episodes and 8 with recurrent depressive disorders. Two (8% were diagnosed with mixed anxiety and depression. Only 5 of 17 patients (29.4% were previously diagnosed with depressive disorder and received prior antidepressant treatment. Duration of epilepsy was significantly higher in patients with depressive disorder (p=0.016, but there was no relationship between depression and seizure frequency. CONCLUSION: This study confirmed that depressive disorders are common and underdiagnosed in patients with TLE refractory to AEDs. Patients with longer duration of epilepsy are at higher risk of having depression.

The acids concentration in the fruit juice is reflected both in the equivalent molecular weight (by lowering it) and in the interaction coefficients b and C. Using the data for the molecular weight and the characteristic coefficients, prediction curves for the samples investigated can be used in practice. Freezing point depression can also be used as an indicator of the degree of spoilage of fruit juices.

    Adjunctive treatment with medication of liver-soothing-oriented method (MLSM) is one of the most commonly used approaches for subjects with depression after cerebrovascular accident (DCVA) in China. The purpose of this meta-analysis was to evaluate the outcome of MLSM treatment in subjects with DCVA using relevant published literature. The PubMed, Cochrane Library, Embase, Chinese databases of China National Knowledge Infrastructure, WanFang, Sinomed, and VIP were used to collect all publications until March 2016. Randomized controlled trials comparing treatments with and without MLSM for subjects with DCVA were included. The quality of each publication was assessed based on the recent Handbook (5.1 version) for Cochrane Reviewers. Cochrane Collaboration's software RevMan 5.3 software was applied for data analysis. Thirty studies, including 2599 cases, were identified and collected. Adjunctive treatment with MLSM noticeably enhanced total effective rates (odds ratio 3.76; 95% confidence interval [CI] 2.92-4.85, I = 0%, P = 0.96) in comparison to non-MLSM conventional pharmacotherapy. Compared to non-MLSM treatment, the changes of Hamilton Depression Scale in adjunctive treatment with MLSM, respectively, decreased and showed beneficial effects after 3 weeks (weighted mean difference [WMD] -4.83; 95% CI -6.82 to -2.83; I = 86%, P < 0.001), 4 weeks (WMD -4.20; 95% CI -5.06 to -3.33; I = 78%, P < 0.001), 6 weeks (WMD -3.36; 95% CI -4.05 to -2.68; I = 54%, P = 0.02), 8 weeks (WMD -4.83; 95% CI -5.62 to -4.04; I = 73%, P < 0.001), and 12 weeks (WMD -2.88; 95% CI -4.09 to -1.67; I = 58%, P = 0.09). As for changes in inflammatory cytokine levels, adjunctive treatment with MLSM was associated with a significant decrease in tumor necrosis factor-α, IL-6, and interleukin-1β levels in comparison to non-MLSM treatment. Moreover, there were positive effects on score changes for National Institute of Health Stroke Scale

    2006-01-01

    Objective: This study is aimed at exploring the relationship between hemodynamic changes and depressive and anxious symptom in depression patients. Methods: The cardiac function indices including the left stroke index (LSI), ejection fraction (EF), heart rate (HR), diastolic pressure mean (DPM), systolic pressure mean (SPM), left ventricle end-diastolic volume (LVDV), effective circulating volume (ECV), resistance total mean (RTM) and blood flow smooth degree (BFSD) were determined in 65 patients with major depressive disorders and 31 healthy normal controls. The clinical symptoms were assessed with Hamilton depression scale (HAMD) and Hamilton anxiety scale (HAMA). Results: In patients with depression without anxiety,LSI, EF, LVDV, DPM, SPM, ECV, BFSD were significantly lower than those in controls, while RTM was higher than that in controls. Patients with comorbidity of depression and anxiety showed decreased LVDV, ECV, BFSD, and increased HR in comparison with the controls. The anxiety/somatization factor score positively correlated with LSI, EF, LVDV, but negatively correlated with RTM. There was negative correlation between retardation factor score and DPM, SPM, LVDV. Conclusion: The study indicated that there are noticeable changes in left ventricle preload and afterload, blood pressure, peripheral resistance, and microcirculation in depressive patients, and that the accompanying anxiety makes the changes more complicated.

    2008-04-01

    Perinatal depression, which may occur from pregnancy to one year after childbirth, is recognized by the World Health Organization as a significant health issue affecting women. Depression during the perinatal period can have enormous consequences, not only affecting the health of the woman herself but also influencing her interaction with her children and other family members. This article introduces several depression screening tools and evidence-based nonpharmacological managements of perinatal depression. There are some fairly valid and feasible screening methods, among which routinely screening perinatal women with EPDS (Edinburgh Perinatal Depression Scale) or BDI (Beck Depression Inventory) in the primary care setting is practicable. A survey of the limited literature available reveals that interpersonal psychotherapy, cognitive behavior therapy and listening to music provide quantifiable depression amelioration effects for perinatal women. More scientific research moderated by women's life experiences and preferences should be conducted, however, and applied to improve women's health.

    2010-01-01

    Objective: To investigate the co-occurrence of migraine and depression and assess whether shared genetic factors may underlie both diseases. Methods: Subjects were 2,652 participants of the Erasmus Rucphen Family genetic isolate study. Migraine was diagnosed using a validated 3-stage screening method that included a telephone interview. Symptoms of depression were assessed using the Center for Epidemiologic Studies Depression scale and the depression subscale of the Hospital Anxiety and Depression Scale (HADS-D). The contribution of shared genetic factors in migraine and depression was investigated by comparing heritability estimates for migraine with and without adjustment for symptoms of depression, and by comparing the heritability scores of depression between migraineurs and controls. Results: We identified 360 migraine cases: 209 had migraine without aura (MO) and 151 had migraine with aura (MA). Odds ratios for depression in patients with migraine were 1.29 (95% confidence interval [CI] 0.98–1.70) for MO and 1.70 (95% CI 1.28–2.24) for MA. Heritability estimates were significant for all migraine (0.56), MO (0.77), and MA (0.96), and decreased after adjustment for symptoms of depression or use of antidepressant medication, in particular for MA. Comparison of the heritability scores for depression between patients with migraine and controls showed a genetic correlation between HADS-D score and MA. Conclusions: There is a bidirectional association between depression and migraine, in particular migraine with aura, which can be explained, at least partly, by shared genetic factors. GLOSSARY CES-D = Center for Epidemiologic Studies Depression Scale; CI = confidence interval; ERF = Erasmus Rucphen Family; HADS-D = Hospital Anxiety and Depression Scale; IHS = International Headache Society; MA = migraine with aura; MO = migraine without aura; OR = odds ratio.

    Ganellen, R J; Blaney, P H

    1984-12-01

    Previous research has found mixed support for the possibility that locus of control moderates the effects of life stress on depression. Two methodological choices may have influenced previous findings: the use of a unidimensional rather than a multidimensional locus of control scale, and reliance on linear statistical methods using median splits. We attempted to correct these choices by using the Levenson IPC scale (1974) and multiple regression analyses in a female undergraduate population (N = 158). The results supported use of a multidimensional scale, since Stress, Internality, and Powerful Others were found to have main effects on depression whereas Chance interacted with life stress. The question of whether locus of control refers to responsibility for causing an event, i.e., self-blame, or belief in control over future events, i.e., coping behavior, was discussed.

    Full Text Available Abstract Background High prevalence of depression has been reported in otorhinolaryngologic patients (ORL. However, studies using a semi-structured interview to determine the prevalence of depression in ORL are lacking. Therefore the present study sought to determine the depression prevalence in ORL applying a semi-structured diagnostic interview and to further characterize the pathopsychological and demographic characteristics of depression in these patients. Methods One-hundred inpatients of the otorhinolaryngologic department of a German university hospital participated voluntarily (age M = 38.8 years, SD = 13.9; 38.0% female. Depression was assessed using a clinical interview in which the International Diagnostic Checklist for depression (IDCL was applied. Patients completed the Brief Symptom Inventory (BSI which constitutes three composite scores and nine symptom scales and the Beck Depression Inventory (BDI. Multivariate analyses of variance, correlations and effect sizes were conducted. Results A prevalence of depression of 21.0% was determined, 38.0% of the depressed patients were female. Depressed patients showed higher scores on the BSI-scales "interpersonal sensitivity", "depression", "anxiety", "phobic anxiety" and "psychoticism" with medium effect sizes. Conclusions High prevalence of depression was found which is in accordance with results of prior studies. Depressed patients showed higher psychological distress as compared to non-depressed patients. The results call for carrying on in engaging in depression research and routine depression screening in ORL.

    Full Text Available Abstract Background Preeclampsia involves endothelial dysfunction, platelet dysfunction/activation and sympathetic over-activity similar to cardiovascular disorders (CVD. Depression, an independent risk factor for progression of CVD, was found to be associated with an increased risk of preeclampsia among Finnish women. We examined the relation between depression/depressive symptoms and preeclampsia risk among Peruvian women. Methods The study included 339 preeclamptic cases and 337 normotensive controls. Depression and depressive symptoms during pregnancy were assessed using the Patient Health Questionnaire (PHQ-9. Odds ratios (OR and 95% confidence intervals (CI were estimated from logistic regression models. Results The prevalence of moderate depression was 11.5% among cases and 5.3% among controls. The corresponding figures for moderate-severe depression were 3.5% for cases and 2.1% for controls. Compared with non-depressed women, those with moderate depression had a 2.3-fold increased risk of preeclampsia (95% CI: 1.2–4.4, while moderate-severe depression was associated with a 3.2-fold (95% CI: 1.1–9.6 increased risk of preeclampsia. Associations of each of the 9-items of the PHQ-9 depression screening module with preeclampsia risk were also observed. Conclusion Our findings are consistent with the only other published report on this topic. Collectively, available data support recent calls for expanded efforts to study and address depression among pregnant women.

    2011-01-01

    This paper describes four nosological categories of depressive disorder according to the fundamental or prime cause: endogen depression, situative depression, psychogen depression and somatogen (also pharmacogen or addictive) depression. Recent advances in neurobiology provide the commun pathogenic mechanism distribuited in neurochemical, neuroendocrine and neuroinmune factors, with at the end a cellular and molecular sequence beyond the synapse. There is an increased risk of depression multiplied by three or four in the elderly, obese, unemployed and inmigrant and it is very frequent in terminally ill patients with a pervasive desire for death. Finally, eight personalized preventive guidelines enable to decrease the individual risk of depression in more than a fifty per cent.

  15. Therapieresistente Depression

    Directory of Open Access Journals (Sweden)

    Holsboer-Trachsler E

    2006-01-01

    Full Text Available In der Behandlung einer Depression wird ein Nichtansprechen auf zwei adäquate Antidepressivatherapien während je 6–8 Wochen als Therapieresistenz bezeichnet. Da häufig zu geringe Dosierungen oder eine zu kurze Behandlungsdauer die Ursache für ein Nichtansprechen sind, sollte in einem ersten Schritt die medikamentöse Therapie hinsichtlich Dauer und Dosierung, eventuell unter Einbezug von Plasmaspiegelbestimmungen, überprüft und optimiert werden. Als pharmakologische Maßnahmen werden zunächst ein Wechsel des Antidepressivums und danach eine Kombination von verschiedenen Antidepressiva mit unterschiedlichem biochemischem Wirkungsansatz empfohlen. Zeigen beide nicht den gewünschten Erfolg, so sollte zusätzlich zur bestehenden Antidepressivabehandlung eine Augmentationstherapie, primär mit Lithium und/oder dem Schilddrüsenhormon T3, durchgeführt werden. Ein neuer, vielversprechender Behandlungsansatz ist eine Augmentationstherapie mit atypischen Neuroleptika. Als akut wirkende nichtpharmakologische Zusatzmaßnahme hat sich der partielle Schlafentzug bewährt. Weitere nichtpharmakologische Strategien umfassen Psychotherapie, Elektrokrampftherapie und Vagusnervstimulationsbehandlung.

  16. [Depressive realism: happiness or objectivity].

    Science.gov (United States)

    Birinci, Fatih; Dirik, Gülay

    2010-01-01

    Realism is described as objective evaluations and judgments about the world; however, some research indicates that judgments made by "normal" people include a self-favored, positive bias in the perception of reality. Additionally, some studies report that compared to normal people, such cognitive distortions are less likely among depressive people. These findings gave rise to the depressive realism hypothesis. While results of several studies verify the notion that depressive people evaluate reality more objectively, other studies fail to support this hypothesis. Several causes for these inconsistent findings have been proposed, which can be characterized under 3 headings. One proposed explanation suggests that what is accepted as "realistic" in these studies is not quite objective and is in fact ambiguous. According to another perspective, the term "depressive" used in these studies is inconsistent with the criteria of scientific diagnostic methods. Another suggests that the research results can only be obtained under the specific experimental conditions. General negativity and limited processing are popular approaches used for explaining the depressive realism hypothesis. Nowadays, the debate over this hypothesis continues. The present review focuses on frequently cited research related to depressive realism and discusses the findings.

    Full Text Available BACKGROUND The elderly experience changes and problems of biologic, psychologic and social dimensions that affect each other. When they are not able to cope with all of these changes there are many emotional disorders that occur in the elderly. One of the most frequently seen disorder is major depression. This study was conducted for the purpose of determining the symptoms of depression in elderly and determining the relationship between sign of depression and sociodemographic factors. METHOD A survey was used in a face-to-face interview method with a group of elderly who were 65 years and older. The questionnaire contained questions about their sociodemographic characteristics. The Beck Depression Inventory was used to evaluate for signs of depression. FINDINGS 53.2% of the elderly had general symptoms of depression and 10.3% severe level of depression. The mean depressive scores of female were higher than those of male. CONCLUSION By calculating the score for signs of depression in the elderly, depression risks can be determined and health care can be provided at an early stage and it will be effective in helping them achieve a higher quality of life. Those who provide primary care and home care services can use this approach to evaluate the elderly for depression. [TAF Prev Med Bull 2008; 7(5.000: 399-404

    Full Text Available Stress related affective disorders have been identified as a core health problem of the 21st century. In the endeavor to identify vulnerability factors, personality has been discussed as a major factor explaining and predicting disorders like depression or burnout. An unsolved question is whether there are specific personality factors allowing differentiation of burnout from depression. The present study tested the relation between one of the most prominent, biological personality theories, Cloninger’s Temperament and Character Inventory (TCI, and common measures of burnout (Maslach Burnout Inventory General and depression (Beck Depression Inventory 2 in a sample of German employees (N=944 and a sample of inpatients (N = 425. Although the same personality traits (harm avoidance and self-directedness were predominantly associated with burnout and depression, there was a much stronger association to depression than to burnout in both samples. Besides, we observed specific associations between personality traits and subcomponents of burnout. Our results underline differences in the association of burnout vs. depression to personality, which may mirror differences in scope: While symptoms of depression affect all aspects of life, burnout is supposed to be specifically related to the workplace and its requirements. The much stronger association of personality to depression can be important to select appropriate therapy methods and to develop a more specified treatment for burnout in comparison to depression.

    Depression is a complex phenomenon thought to be due to the interaction of biological, psychological and social factors. Currently depression assessment uses self-reported depressive symptoms but this is limited in the degree to which it can characterise the different expressions of depression emerging from the complex causal pathways that are thought to underlie depression. In this study, we aimed to represent the different patterns of depression with pattern values unique to each individual, where each value combines all the available information about an individual’s depression. We considered the depressed individual as a subsystem of an open complex system, proposed Generalized Information Entropy (GIE) to represent the general characteristics of information entropy of the system, and then implemented Maximum Entropy Estimates to derive equations for depression patterns. We also introduced a numerical simulation method to process the depression related data obtained by the Diamond Cohort Study which has been underway in Australia since 2005 involving 789 people. Unlike traditional assessment, we obtained a unique value for each depressed individual which gives an overall assessment of the depression pattern. Our work provides a novel way to visualise and quantitatively measure the depression pattern of the depressed individual which could be used for pattern categorisation. This may have potential for tailoring health interventions to depressed individuals to maximize health benefit.

METHODS: 146 patients from a previous study in general practice with the CID were investigated. The item response theory model established by Rasch was used to investigate the scalability (a scale......׳s psychometric adequacy) of the subscales, and principal component analysis was used to identify subsyndromes with the symptoms of major depression according to DSM-5 or ICD-10. RESULTS: Whereas the HAM-D17 was found not to have an acceptable scalability, the three brief CID subscales for depression (six items......), anxiety (five items), and apathy (five items) all had an acceptable scalability. Within the major depressive symptoms, principal component analysis identified the CID items of hypersomnia, increased appetite or weight gain as defining the subsyndrome of atypical depression.

    Full Text Available Objective: To classify families of elderly with depressive symptoms regarding their functioning and to ascertain the presence of an association between these symptoms, family functioning and the characteristics of the elderly. Method: This was an observational, analytical, cross-sectional study performed with 33 teams of the Family Health Strategy in Dourados, MS. The sample consisted of 374 elderly divided into two groups (with and without depressive symptoms. The instruments for data collection were a sociodemographic instrument, the GeriatricDepression Scale (15 items and the Family Apgar. Results: An association was observed between depressive symptoms and family dysfunction, female gender, four or more people living together, and physical inactivity. Conclusion: The functional family may represent effective support for the elderly with depressive symptoms, because it offers a comfortable environment that ensures the well-being of its members. The dysfunctional family can barely provide necessary care for the elderly, which can exacerbate depressive symptoms.

    Among various research strategies for depression, the cross-cultural approach is a useful tool to investigate depressive disorders. The Hamilton Rating Scale for Depression was applied to 130 depressed inpatients in France and Brazil. Items were factorized by principal component analysis with Varimax rotation using the Kaiser or simulation method for factor sorting. Three factors were obtained in France, and four in Brazil. The first factor includes the core symptoms of depression in both samples. Qualitative and quantitative differences appeared in the anxiety factor between Brazilian and French samples. Insomnia items appeared as another factor for both groups. A limitation of this study is that it was conducted with small inpatient samples. Principal component analysis of the Hamilton Rating Scale for Depression for depressive inpatients in these two countries showed a similar structure. Differences observed were in the way anxiety items were distributed.

    Full Text Available Abstract Background Depression is one of the most common mental disorders in Western countries and is related to increased morbidity and mortality from medical conditions and decreased quality of life. The sociodemographic factors of age, gender, marital status, education, immigrant status, and income have consistently been identified as important factors in explaining the variability in depression prevalence rates. This study evaluates the relationship between depression and these sociodemographic factors in the province of Ontario in Canada using the Canadian Community Health Survey, Cycle 1.2 (CCHS-1.2 dataset. Methods The CCHS-1.2 survey classified depression into lifetime depression and 12-month depression. The data were collected based on unequal sampling probabilities to ensure adequate representation of young persons (15 to 24 and seniors (65 and over. The sampling weights were used to estimate the prevalence of depression in each subgroup of the population. The multiple logistic regression technique was used to estimate the odds ratio of depression for each sociodemographic factor. Results The odds ratio of depression for men compared with women is about 0.60. The lowest and highest rates of depression are seen among people living with their married partners and divorced individuals, respectively. Prevalence of depression among people who live with common-law partners is similar to rates of depression among separated and divorced individuals. The lowest and highest rates of depression based on the level of education is seen among individuals with less than secondary school and those with "other post-secondary" education, respectively. Prevalence of 12-month and lifetime depression among individuals who were born in Canada is higher compared to Canadian residents who immigrated to Canada irrespective of gender. There is an inverse relation between income and the prevalence of depression (p Conclusion The patterns uncovered in this

    Full Text Available Abstract Background Depression is a global health challenge. Although there are effective psychological and pharmaceutical interventions, our best treatments achieve remission rates less than 1/3 and limited sustained recovery. Underpinning this efficacy gap is limited understanding of how complex psychological interventions for depression work. Recent reviews have argued that the active ingredients of therapy need to be identified so that therapy can be made briefer, more potent, and to improve scalability. This in turn requires the use of rigorous study designs that test the presence or absence of individual therapeutic elements, rather than standard comparative randomised controlled trials. One such approach is the Multiphase Optimization Strategy, which uses efficient experimentation such as factorial designs to identify active factors in complex interventions. This approach has been successfully applied to behavioural health but not yet to mental health interventions. Methods/Design A Phase III randomised, single-blind balanced fractional factorial trial, based in England and conducted on the internet, randomized at the level of the patient, will investigate the active ingredients of internet cognitive-behavioural therapy (CBT for depression. Adults with depression (operationalized as PHQ-9 score ≥ 10, recruited directly from the internet and from an UK National Health Service Improving Access to Psychological Therapies service, will be randomized across seven experimental factors, each reflecting the presence versus absence of specific treatment components (activity scheduling, functional analysis, thought challenging, relaxation, concreteness training, absorption, self-compassion training using a 32-condition balanced fractional factorial design (2IV 7-2.

    Depressive symptoms are frequent during schizophrenia. Depression occurs in the course of a schizo affective psychose or in the course of a schizophrenia (either with acute psychotic symptoms, either without acute psychotic symptoms). Differentiating depression from negative symptoms of schizophrenia or from antipsychotic drug induced side effects can be difficult. The question to know whether depression is intrinsic to the disease process itself whether it is secondary to the schizophrenic process is still a matter of inquiry. Efficacy of antidepressive drugs during depression in schizophrenia remains a matter of controversy. Depression increases the risk for pejorative evolution and for suicide in schizophrenia.

Screening for Depression in Hospitalized Pediatric Patients. Iran J Child Neurol. 2014 Winter; 8(1:47-51. Objective In chronically ill children who are hospitalized, many mood changes occur. For example, in children with cancer or renal failure, prolonged hospitalization and chemotherapy can lead to depression. With the improved survival of childhood malignancies, the effect of treatment on child’s psychosocial well-being becomes increasingly relevant. In this study, we examined the prevalence of depression in hospitalized children with chronic and acute conditions in Dr Sheikh Pediatrics Hospital in Mashhad. Materials & Methods After receiving the approval from the Ethics Committee of Mashhad University of Medical Sciences, we did this cross-sectional descriptive study, from April to June 2012 in Dr Sheikh Pediatric Hospital in Mashhad. Ninety children, aged between 8 to 16 years, were screened for depression. The sampling method was census. Children with a history of depressive or other mental disorders were excluded. Three groups of children (children with chronic renal disease, malignancy, and acute disease were evaluated for depression using standard Children Depression Inventory Questionnaire (CDI. Two specifically trained nurses with the supervision of a psychiatrist filled out the questionnaires at patients’ bedside. Depression scores were then analyzed by SPSS software. Results Of 90 children, 43(47.7% were male and 47(52.2% were female. The Children’s mean age was 11±2.3 years, and the mean length of hospitalization was 8±5.3 days.

    Full Text Available Background. Irritable bowel syndrome (IBS is associated with depression and depression with impaired cognitive functions. The primary aim was to study associations between depression and cognitive functions in patients with IBS. Methods. IBS (according to the Rome III criteria, cognitive functions (evaluated with a set of neuropsychological tests, and depression (measured with Beck Depression Inventory II and Montgomery-Åsberg Depression Scale were analysed in patients with idiopathic depression and in patients with unspecified neurological symptoms. Results. 18 and 48 patients with a mean age of 47 and 45 years were included in the “Depression” and “Neurological” group, respectively. In the “Depression” group, the degree of depression was significantly higher in patients with IBS than in those without. Depression was associated with impaired cognitive function in 6 out of 17 neuropsychological tests indicating reduced set shifting, verbal fluency, attention, and psychomotor speed. IBS was statistically significantly associated with depression but not with any of the tests for cognitive functions. Conclusions. IBS was associated with depression but not with impaired cognitive functions. Since the idiopathic depression was associated with cognitive deficits, the findings could indicate that the depression in patients with IBS differs from an idiopathic depression.

METHODS: A prospective cohort study of 57 patients of both sexes undergoing coronary artery bypass grafting between June 2010 and June 2011. We used the SF-36 to assess quality of life, and the Beck Depression Inventory to detect depressive symptoms, applied preoperatively and six months. RESULTS: The prevalence of patients aged 60-69 years was 22 patients (38.60%, 39 men (68.42%, 26 described themselves as mixed race (45.61%, 16 literate (28.07 % and 30 married (52.63%. The beck depression inventory score demonstrated increased after revascularization: 15 patients mild (26.32% at time zero to 17 (29.82% after. And with moderate, seven patients (12.28% before and 10 (17.54% after. In the categories of individuals with decreased minimum degree of 32 (56.14% to 28 (49.12%, and severe of three (5.26% for two (3.51% patients. Association was observed between beck depression inventory, gender, age, lifestyle, comorbidities and quality of life. CONCLUSION: There was a high prevalence of elevated beck depression inventory scores, lowest scores of depressive symptoms among men and association between the improvement of quality of life scores and beck depression inventory.

    2012-12-01

    In this review, we present an overview of clinical studies that addressed the relationship between depression and dementia or cognitive decline. Cross-sectional studies and meta-analyses have repeatedly shown an association between late-life depression (LLD) and dementia, particularly Alzheimer's disease (AD) and vascular dementia; however, the findings of cohort studies have been inconsistent. Furthermore, studies on the association between depression with a younger age of onset and dementia have yielded inconsistent results. Regarding cognitive decline associated with LLD, several studies have reported an association between LLD and mild cognitive impairment, suggesting that depression itself can cause persistent cognitive impairment. Other studies have compared the cognitive profile between LLD and depression with a younger age of onset, but their results have been inconclusive, especially regarding the association between memory impairment and the age of onset of depression. LLD is associated with vascular change and white matter degeneration of the brain, as shown by magnetic resonance imaging (MRI). Recently, several studies reported an association between gray matter change and LLD. Studies currently in progress employ functional brain imaging methods such as single-photon emission computed tomography, functional MRI, and positron emission tomography. Clinically, it is important to understand how subtypes of depression can be defined in terms of risk of developing dementia, and to devise effective treatments. One paper explored the possibility of detecting depression associated with AD by measuring the blood Aβ40/Aβ42 levels, and other studies have suggested that symptoms of apathy and loss of interest are associated with conversion of depression to AD. Unfortunately, current antidepressants may have limited efficacy on depression with dementia; therefore, further investigation for devising methods of predicting conversion of depression to dementia and

    Postpartum depression is a prevalent disorder affecting many women of reproductive age. Despite increasing public awareness, it is frequently underdiagnosed and undertreated leading to significant maternal morbidity and adverse child outcomes. When identified, postpartum depression is usually treated as major depressive disorder. Many studies have identified the postpartum as a period of high risk for first presentations and relapses of bipolar disorder. Areas covered: This article reviews the acute and prophylactic treatment of postpartum major depressive disorder, bipolar depression and major depressive disorder with mixed features. The safety of antidepressant and mood stabilizing medications in pregnancy and breastfeeding will also be reviewed. Expert commentary: Differentiating postpartum major depressive disorder and postpartum bipolar depression can be difficult given their clinical similarities but accurate identification is vital for initiating proper treatment. Antidepressants are the mainstay of drug treatment for postpartum major depressive disorder, yet randomized controlled trials have shown conflicting results. A paucity of evidence exists for the effectiveness of antidepressant prophylaxis in the prevention of recurrences of major depressive disorder. Mood stabilizing medications reduce the risk of postpartum bipolar depression relapse but no randomized controlled trials have examined their use in the acute or prophylactic treatment of postpartum bipolar depression.

    Full Text Available Introduction: Childbearing years in the women’s life are associated with the highest risk of depression. Despite the results of some studies that suggested, depression during pregnancy has been associated with poor prenatal care, substance abuse, low birth weight, and preterm delivery and introduced antenatal depression and anxiety as predictors of postnatal depression, researches during past 25 years have focused mostly on postpartum depression so depression during pregnancy is relatively neglected. Materials and methods: We studied depression during third trimester of pregnancy and after delivery, using prospectively gathered data from a cohort of 1898 women. We compared depressive symptom score and the proportion of mothers above a threshold, to indicate probable depressive disorder at each stage. Results: Point prevalence of depressed pregnant women (clinical depression based on BDI score greater than 20 in last trimester of pregnancy, was 22.8% and postnatal rate of depression based on EPD score greater than 12 between 6 to 8 weeks after delivery, was 26.3%. Incidence of PPD in 6 to 8 weeks after delivery in those who were not clinically depressed during pregnancy was, 20.1%. Discussion: We found that history of depression, unplanned pregnancy; being housewife and having 3 or more children were variables with significant relation to ante partum depression. Two main risk factors for post partum depression in this cohort study, were previous history of depression and depression during current pregnancy that highlight the importance of these two variables assessment during pregnancy in order to facilitate timely identification of women at risk.

    Full Text Available Background Every woman during different stages of her growth faces various crises, and one of these crises, menopause, may create different problems. In modern societies, psychological disorders and particularly depression is one of the problems of menopausal women. Objectives This study aimed to evaluate the prevalence of depression in postmenopausal women referred to selected health centers of Ahvaz in 2014. Patients and Methods This study was cross-sectional study. In this study, 1280 postmenopausal women aged between 40 and 65 years old who were referred to selected health centers of Ahvaz in 2014 were randomly enrolled. Hamilton depression scale and demographic questionnaire were used for gathering information. Data were analyzed using SPSS software. To analyze the data, descriptive statistics and analytical statistics (Independent t test, ANOVA, Pearson correlation and logistic regression were carried out (CI 95%. Results The mean ± SD score of depression for the subjects was 9.37 ± 4.62. The results showed that 59.8% of the 1280 samples were depressed; in particular, 39.8% had mild depression, 16% moderate depression, and 4% severe depression. There is a significant and inverse relation between variables of age, exposure to cigarette smoking, and the relationship with their spouses and the level of their depression, so higher age, more exposure to smoking, and better relation with their husbands, lead to the less depression. The results showed that the level of education is associated with depression. The highest rate of depression was in illiterate women; the finding also showed that there is a relationship between income and the severity of depression (Regression Log. T test showed that the mean depression level of employed postmenopausal women is higher than housewives postmenopausal women, and this difference is statistically significant (P < 0.001. Conclusions A significant percentage of women in their menopause experience

    2012-12-11

    A method is presented for producing and isolating an isotopically enriched compound of a desired isotope from a parent radionuclide. The method includes forming, or placing, a precipitate containing a parent radionuclide of the desired daughter isotope in a first reaction zone and allowing sufficient time for the parent to decay into the desired gaseous daughter radioisotope. The method further contemplates collecting the desired daughter isotope as a solid in a second reaction zone through the application of temperatures below the freezing point of the desired isotope to a second reaction zone that is connected to the first reaction zone. Specifically, a method is presented for producing isotopically enriched compounds of xenon, including the radioactive isotope Xe-131m and the stable isotope Xe-131.

    Full Text Available Background: Neurotransmitters, such as dopamine and serotonin, play an undeniable role in the incidence of mental illnesses. Almost all humans will experience depression. Furthermore, most humans lack the ability to control and reduce depression, the disorder can lead to physical damage. The main goal of this study was to determine the association between distribution of depression and the climatic conditions in the Iran country. Methods: Spatial distribution maps of depression were plotted by using data recorded during 2010 year in the Iran health center registry. The geographical mapping of depression and climatic conditions were then incorporated into a geographic information system to create a spatial distribution model and in this study we used neural network to model the trend of depression and climatic conditions. Results: The spatial distributions of depression diseases in the country, followed by were scattered based on climatic conditions. In fact, common depression was more prevalent in the parts of the country where cold and rainy weather was more abundant. Conclusions: The findings of this study can be useful for psychologists and controlling of this disease, because lack the ability to control and reduce depression, the disorder can lead to physical damage. Data are also important to establish further effects modeling for depression. Moreover, psychologists and health professionals should consider the impact of environmental factors on their patients′ health.

    Full Text Available Background: The present study compared people with depressive symp¬toms and people without depressive symptoms with reference to their coping styles, level of aggression and interpersonal conflicts.Methods: A purposive sample of 128 people (64 depressed and 64 normal controls was selected from four different teaching hospitals of Lahore. Both the groups were matched on four demographic levels i.e. age, gender, education and monthly income. Symptom Checklist-R was used to screen out depressed and non-depressed people. The Brief COPE, the Aggres¬sion Questionnaire and the Bergen Social Relationship Scale were used to assess coping styles, aggression and interpersonal conflicts respectively. The Independent t-test was used to compare the groups. Binary logistic Regression was also carried out to predict the role of research variables in causing depression.Results: The results showed that level of aggression and interpersonal conflict was significantly more in people with depressive symptoms as compared to control group. On the other hand control group was using more adaptive coping styles than people with depressive symptoms but no difference was found in the use of maladaptive coping styles. Conclusion: The present findings revealed that coping styles, aggression and interpersonal conflicts play important role in depression. Therefore, these dimen-sions must be considered while dealing with the depressive patients. Implications for preventive work are also discussed in the light of previous researches.

    2014-01-01

    Full Text Available Background: Maternal prenatal mental health has been shown to be associated with adverse consequences for the mother and the child. However, studies considering the effect of prenatal depressive symptoms are lacking. The aim of this study was to examine the influence of antenatal depressive symptoms on obstetric outcomes and to determine associations between antenatal and postpartum depressions. Materials and Methods: This was a prospective cohort study. The Edinburgh postnatal depression scale (EPDS questionnaire was completed by pregnant women receiving obstetrical care at Seoul St. Mary′s hospital in the third trimester of gestation. The electronic medical records were reviewed after delivery and perinatal outcomes were evaluated. The association between antenatal and postpartum depression was analyzed using the EPDS questionnaire, which was completed by the same women within 2 months of delivery. Results: Of the 467 participants, 26.34% (n = 123 had antenatal depressive symptoms, with EPDS scores of ≥10. There were no significant perinatal outcomes associated with antenatal depressive symptoms. During the postpartum period, 192 of the women in the initial study cohort were given the EPDS again as a follow-up. Of the 192 participants, 56 (29.17% scored >10. Spearman correlation coefficient between the antenatal and postpartum EPDS scores was 0.604, which was statistically significant (P < 0.001. Conclusion: Antenatal depression does not lead to unfavorable perinatal outcomes. However, screening for antenatal depression may be helpful to identify women at risk of postpartum depression.

    Major depressive disorder in children is a severe and a chronically disabling disorder. This population appears to be a special group in terms of consequences of poor psychosocial and academic outcome and increased risk of substance abuse, and suicide. Studies have revealed several major findings in genetic, familial, psychological, and biological aspects of such depression, some of which have explored into the issue of its relationship with adult depression. Considerable advances have been made now in the area of childhood depression providing a better understanding of its nature. We review literature available on historical aspect, epidemiology, clinical characteristics, and aetiology of childhood depression.

  9. Fractalkine depresses cardiomyocyte contractility.

    Directory of Open Access Journals (Sweden)

    David Taube

    Full Text Available BACKGROUND: Our laboratory reported that male mice with cardiomyocyte-selective knockout of the prostaglandin E2 EP4 receptor sub-type (EP4 KO exhibit reduced cardiac function. Gene array on left ventricles (LV showed increased fractalkine, a chemokine implicated in heart failure. We therefore hypothesized that fractalkine is regulated by PGE2 and contributes to depressed contractility via alterations in intracellular calcium. METHODS: Fractalkine was measured in LV of 28-32 week old male EP4 KO and wild type controls (WT by ELISA and the effect of PGE2 on fractalkine secretion was measured in cultured neonatal cardiomyocytes and fibroblasts. The effect of fractalkine on contractility and intracellular calcium was determined in Fura-2 AM-loaded, electrical field-paced cardiomyocytes. Cardiomyocytes (AVM from male C57Bl/6 mice were treated with fractalkine and responses measured under basal conditions and after isoproterenol (Iso stimulation. RESULTS: LV fractalkine was increased in EP4 KO mice but surprisingly, PGE2 regulated fractalkine secretion only in fibroblasts. Fractalkine treatment of AVM decreased both the speed of contraction and relaxation under basal conditions and after Iso stimulation. Despite reducing contractility after Iso stimulation, fractalkine increased the Ca(2+ transient amplitude but decreased phosphorylation of cardiac troponin I, suggesting direct effects on the contractile machinery.

    While the most serious of depressive illnesses in the elderly is major depressive disorder, patients' quality of life can be significantly impacted by dysthmic disorder, sub-threshold depression (minor depression), or a depressive disorder due to a general medical condition, all of which have been shown to be more prevalent than major depression in the community dwelling population of older adults. Older adults are also more likely to develop grief reaction and frequently deal with issues of bereavement. This review will discuss the diagnoses of all relevant depressive diagnoses that primary care physicians are likely to encounter. Among the many different assessment tools that screen for depression the briefest instruments are a two-question screening tool recommended by the U.S. Preventive Services Task Force and, specifically developed for older adults, the Geriatric Depression Scale (GDS) that is available in a short 15- Yes/No-question version. Many medical illnesses are associated with depressive symptoms. The focus in this review is on dementing illnesses/cerebrovascular disease, dementia of the Alzheimer's type, and Parkinson disease. First-line pharmacological therapy of depression includes selective serotonin inhibitors (SSRIs), and serotonin-norepinephrine reuptake inhibitors (SNRIs). Side effects of particular drugs can often be geared towards achieving additional benefits, e.g. weight gain associated with the use of some SSRISs may be helpful for patients with dementia.

This study was a subanalysis of the Neurological Disorders in Central Spain (NEDICES study. Past and present depression, VFs, dementia status, and dementia due to AD were documented at study inception. Dementia status was also documented after three years. Four groups were created according to baseline data: never depression (nD, past depression (pD, present depression (prD, and present and past depression (prpD. Logistic regression was used. Results. Data of 1,807 subjects were investigated at baseline (mean age 74.3, 59.3% women, and 1,376 (81.6% subjects were evaluated after three years. The prevalence of dementia at baseline was 6.7%, and dementia incidence was 6.3%. An effect of depression was observed on dementia prevalence (OR [CI 95%] 1.84 [1.01–3.35] for prD and 2.73 [1.08–6.87] for prpD, and on dementia due to AD (OR 1.98 [0.98–3.99] for prD and OR 3.98 [1.48–10.71] for prpD (fully adjusted models, nD as reference. Depression did not influence dementia incidence. Conclusions. Present depression and, particularly, present and past depression are associated with dementia at old age. Multiple mechanisms, including toxic effect of depression on hippocampal neurons, plausibly explain these associations.

    Full Text Available Background & Objectives: Diabetes and depression are highly prevalent conditions and have significant impact on health outcomes. The combination of depression with type 2 diabetes is a public health problem. Therefore, we aimed to assess some socio-demographic characteristics of type 2 diabetes and to investigate the relationship between type 2 diabetes and depression among patients aged from 40 to 60 years old. Methods: 125 patients diagnosed with type 2 diabetes attending diabetes clinics in the Al-Zahraa hospital were invited to participate in this cross-sectional study. Patients were interviewed using structured questionnaires to gather data on socio-demographics, clinical, self care compliance, medication usage, and diabetes complications. The MADRS was administered as a screening tool for depression level evaluation. Binary logistic regression model was used to examine association between predictor variables and risk of depression among diagnosed type 2 diabetes at 95% C.I. and P < 0.05. Results: One hundred and twenty five participants completed the interview. More than half of participants were females (58.4% and the mean age was 48 (sd = 5.9, 47.2% hypertensive, and 59.2% on insulin. More than two third (74.4% of patients were depressed; (24.8% mild, 37.6% moderate and 12% severely depressed. Almost four out of five patients (88.8% had diabetes complications, Depression was strongly associated with neuropathy, age, retinopathy, sex and cardiac complications. However, the likelihood of depression was not associated with nephropathy, hypertension and sexual dysfunction. Conclusion: The current study demonstrates a strong correlation between depression and diabetes particularly complications. In particular, patients who are depressed tended to have poorer self-care, more severe physical symptoms and were less likely to adhere to prescribed care regimens. These findings raise the possibility that improving the mental health as part of a

    Unipolar depressive disorder in adolescence is common worldwide but often unrecognised. The incidence, notably in girls, rises sharply after puberty and, by the end of adolescence, the 1 year prevalence rate exceeds 4%. The burden is highest in low-income and middle-income countries. Depression is associated with sub stantial present and future morbidity, and heightens suicide risk. The strongest risk factors for depression in adolescents are a family history of depression and exposure to psychosocial stress. Inherited risks, developmental factors, sex hormones, and psychosocial adversity interact to increase risk through hormonal factors and associated perturbed neural pathways. Although many similarities between depression in adolescence and depression in adulthood exist, in adolescents the use of antidepressants is of concern and opinions about clinical management are divided. Effective treatments are available, but choices are dependent on depression severity and available resources. Prevention strategies targeted at high-risk groups are promising. PMID:22305766

    In many neurological diseases a depressive syndrome is a characteristic sign of the primary disease or is an important comorbidity. Post-stroke depression, for example, is a common and relevant complication following ischemic brain infarction. Approximately 4 out of every 10 stroke patients develop depressive disorders in the course of the disease which have a disadvantageous effect on the course and the prognosis. On the other hand depression is also a risk factor for certain neurological diseases as was recently demonstrated in a meta-analysis of prospective cohort studies which revealed a much higher stroke risk for depressive patients. Furthermore, depression plays an important role in other neurological diseases with respect to the course and quality of life, such as Parkinson's disease, multiple sclerosis and epilepsy. This article gives a review of the most important epidemiological, pathophysiological and therapeutic aspects of depressive disorders as a comorbidity of neurological diseases and as a risk factor for neurological diseases.

    Depression is the most common mental health problem in palliative care, yet it's widely misunderstood, underdiagnosed, undertreated and considered a complex medical task. Psychological distress is a major cause of suffering among patients and families and it's highly correlated with reduced quality of life and amplification of pain. Terminally-ill individuals who suffer from depression are also at high risk of suicide and desire for a hastened death. Every patient receiving palliative care should receive a complete personal and familial psychiatric history, with risk factors, as well as the typical signs and symptoms in the terminal disease. There are two different approaches to assess depression in palliative care: Categorial vs Dimensional The Hospital Anxiety and Depression Scale (HADS) is the most used assessment method for depression in advanced disease and it's validated to the Portuguese population. HADS overcomes the biggest problem when evaluating depression in the terminally-ill: the influence of somatic symptoms due to the underlying disease on the results of the depression scales. In this article we revise other approaches for the assessment of depression in advanced disease: single question vs two-item question; structured clinical interview and diagnostic criteria. Clinicians who care for terminally-ill patients must develop competences on the psychological area, developing state-of-the-art clinical skills that provide quality of life and comfort to patients and their families.

    Full Text Available Introduction The role of attribution in psychopathology has been investigated most systematically within the depression context. The presumption which makes people depressive consists, to an excessive degree, of internal, stable and global attributions to negative occurrences. Negative attributions for unpleasant events are associated with the loss of self-respect which follows. Objective Establishing the characteristics of attribution style of depressive patients. Methods The investigation included 62 subjects. The first group consisted of 32 patients with endogenous depression in remission. The second group included 30 healthy subjects. The characteristics of attribution style, in both groups, were tested by the Attribution Style Questionnaire (ASQ. Results The group of depressive patients, in comparison with healthy subjects, exhibited a significantly more marked internal attribution for negative events (t(60=-3.700; p<0.01 and global internal negative attributions (t(60=-4.023; p<0.01. There was no significant difference between the groups in the stability of these negative attributions (t(60=-1.937; p>0.05, and also the composite score which represents the measure of hopelessness did not make a significant difference between depressive and healthy subjects (t(60=-1.810; p>0.05. Conclusion Depressive patients exhibit an inclination towards internal and global attribution for negative events. These negative attributions do not have stable character, i.e. these attributions vary in time. Characteristics of attribution judgments of depressive people do not represent a permanent pattern within their cognitive style.

    Full Text Available Introduction: Biological, physical and phsycosocial changes in stroke patient could be a stressor that induced a depression state. There would be an emotional disturbance in stroke patient and stroke attack would be recurrent, if it was not treated. One of the alternative techniques to reduce depression is musical therapy especially memory songs. Method: This study was used a quasy experimental pre-post test purposive sampling design. The population was stroke patients who treated in Neurological Ward A and Stroke Unit Dr Soetomo Hospital Surabaya. There were 12 respondents divided into 6 respondents for treatment group and 6 respondents for control group. The independent variable was music (memory song and dependent variable was depression. Data were collected by using questionnaire which adapted from Hamilton Depression Rating Scale and Geriatric Depression Rating Scale, then analyzed by using Wilcoxon Signed Rank Test and Mann Whitney U Test with significance level α≤0.05. Result: The result showed that there was a difference between pre test and post test in depression (p=0.0196 and there was a difference in the depression between treatment group and control group (p=0.002. Discussion: It can be concluded that music (memory songs has an effect to the depression of stroke patient. Further studies are needed to concerning other factors that may affect the relaxation technique especially in listening music.

    Full Text Available Abstract Background Information on clinical acceptability is needed when making cost-utility decisions about health screening implementation. Despite being in use for two decades, most data on the clinical acceptability of the Edinburgh Postnatal Depression Scale (EPDS come from qualitative reports, or include relatively small samples of depressed women. This study aimed to measure acceptability in a survey of a relatively large, community sample with a high representation of clinically depressed women. Methods Using mail, telephone and face-to-face interview, 920 postnatal women were approached to take part in a survey on the acceptability of the EPDS, including 601 women who had screened positive for depression and 245 who had received DSM-IV diagnoses of depression. Acceptability was measured on a 5-point Likert scale of comfort ranging from "Not Comfortable", through "Comfortable" to "Very Comfortable". Results The response rate was just over half for postal surveys (52% and was 100% for telephone and face-to-face surveys (432, 21 and 26 respondents for postal, telephone and face-to-face surveys respectively making 479 respondents in total. Of these, 81.2% indicated that screening with the EPDS had been in the range of "Comfortable" to "Very Comfortable". The other 18.8 % rated screening below the "Comfortable" point, including a small fraction (4.3% who rated answering questions on the EPDS as "Not Comfortable" at the extreme end of the scale. Comfort was inversely related to EPDS score, but the absolute size of this effect was small. Almost all respondents (97% felt that screening was desirable. Conclusion The EPDS had good acceptability in this study for depressed and non-depressed women. Women's views on the desirability of postnatal depression screening appear to be largely independent of personal level of comfort with screening. These results should be useful to policy-makers and are broadly supportive of the Edinburgh Postnatal

    Depression is common and an important consequence of stroke but there is limited information on the longer-term relationship between these conditions. To identify the prevalence, incidence and predictors of depression in a secondary-care-based cohort of stroke survivors aged over 75 years, from 3 months to up to 10 years post-stroke. Depression was assessed annually by three methods: major depression by DSM-IV criteria, the self-rated Geriatric Depression Scale (GDS) and the observer-rated Cornell scale. We found the highest rates, 31.7% baseline prevalence, of depressive symptoms with the GDS compared with 9.7% using the Cornell scale and 1.2% using DSM-IV criteria. Incidence rates were 36.9, 5.90 and 4.18 episodes per 100 person years respectively. Baseline GDS score was the most consistent predictor of depressive symptoms at all time points in both univariate and multivariate analyses. Other predictors included cognitive impairment, impaired activities of daily living and in the early period, vascular risk factor burden and dementia. Our results emphasise the importance of psychiatric follow-up for those with early-onset post-stroke depression and long-term monitoring of mood in people who have had a stroke and remain at high risk of depression.

A subset of schemas called Early Maladaptive Schemas (EMS which are hyphotised to arise from early traumatic and adverse life events are also claimed to be related with not only personality disorders but also mood disorders. In this study we aimed to investigate the relationship between early maladaptive schemas and depression and relationship between schema scores and depression severity in depressed women and compare it with non-depressed controls.Methods: 40 women attending to an outpatient psychiatry clinic and 30 healthy controls participated. All participants were assessed with SCID-1. Data were obtained by using a Sociodemographic Questionnaires, Young Schema Questionnaire-Short Form 3 (YSQ and Beck Depression Inventory (BDI.Results: All except one (enmeshment/undeveloped self maladaptive schema scores of depressed women were higher than controls. BDI was correlated to some schema and schema domain scores in both depressed and control groups but the correlations were stronger in control group. Mean emotional deprivation, negativism, abandonment and instability, failure EMS scores showed the highest difference between two groups. The schema domains most related to depression symptom severity were disconnection and rejection, impaired autonomy and performance.Conclusions: Almost all early maladaptive schemas are related to depression, and some schemas are related to depression symptom severity but these correlations are weaker in control group. This may mean that EMS are stable and mood independent structures. Although other schemas are related to depression, mostly related EMS in women might be emotional deprivation schema. These schemas may also overlap with Beck’s unlovability core belief or sociotropy dimension

    Full Text Available Introduction & Objective: Despite the high prevalence of depression and hypertension, the relationship between these disorders has received little attention. Some prospective studies indicate that depression poses a risk factor for hypertension. Depression has been found to be associated with an increased risk of developing cardiovascular diseases. The present study was conducted to examine the prevalence of depression in hypertensive patients' refering to medical and health centers in Hamadan city.Materials & Methods: In a descriptive cross-sectional study 525 hypertensive patients who referred to the medical and health centers of Hamadan city in 2008 were studied. Depression status was evaluated by Beck depression inventory. Obtaining a score higher than 18 indicated depression. The data were analyzed with SPSS software(version 10 , chi-square and parson regression coefficient tests Results: Depression prevalence in the hypertensive patients was 48.6%. Positive correlation was detected between age and score of depression(r=0.56 P.V=0.000. The rate of depression was significantly higher in the females than the males (2=34 P.V=<0.5. Depression prevalence in the lower socioeconomic classes and the widows were higher than in the married and high class patients (P.V<0.05.Conclusion: Hypertensive patients are prone to depression. The lifetime co- morbidity of two diseases is significantly higher in females than males. The presence of a positive correlation between hypertension and depression indicates that hypertension is a risk factor for developing depression .High prevalence of depression suggests the need for depression screening and neurological consultation in hypertensive patients.

    Full Text Available Depressive disorders are the most frequent psychiatric comorbidity in epilepsy but very often remain unrecognized and untreated. We examined 103 epileptic patients, aged 18-60 years, 40 males and 63 females, for the presence of interictal depressive disorder. All subjects underwent clinical psychiatric examination, including evaluation on Hamilton Depression Rating Scale (HAM-D-17. A questionnaire for demographic and seizure-related variables was also completed. Concurrent depressive disorder (clinically presented according to ICD-10 diagnostic criteria affected 28.3% of all evaluated patients. Based on HAM-D-17 scores depression was defined as mild - 80% of all depressed patients, moderate - 17% and severe - 3%. Atypical presentation of interictal depressive disorder was frequent. Depression has a tremendous effect on one’s family, social and psychological functioning, even more than the actual seizure frequency and severity. Diagnostic difficulties come through the atypical mode of presentation of depressive disorders in epilepsy. Proper neuropsychiatric evaluation is essential for improving treatment and quality of life for patients with epilepsy.

  1. Depression after myocardial infarction.

    2001-01-01

    Depression is an independent risk factor for increased postmyocardial infarction morbidity and mortality, even after controlling for the extent of coronary artery disease, infarct size, and the severity of left ventricular dysfunction. This risk factor takes on added significance when one considers that almost half of patients recovering from a myocardial infarction have major or minor depression and that major depression alone occurs in about one in five of these individuals. Despite the well-documented risk of depression, questions remain about the mechanism of the relationship between mood disturbance and adverse outcome. The link may be explained by an association with lower levels of social support, poor adherence to recommended medical therapy and lifestyle changes intended to reduce the risk of subsequent cardiac events, disturbances in autonomic tone, enhanced platelet activation and aggregation, and systemic immune activation. Unfortunately, questions about the pathophysiologic mechanism of depression in this setting are paralleled by uncertainties about the optimal treatment of depression for patients recovering from a myocardial infarction and by a lack of knowledge about whether treating depression lowers the associated increased mortality risk. Ongoing research studies will help to determine the benefits of psychosocial interventions and of antidepressant therapy for patients soon after myocardial infarction. Although the identification of depression as a risk factor may by itself be a reason to incorporate a comprehensive psychological evaluation into the routine care of patients with myocardial infarction, this practice should certainly become standard if studies show that treating depression reduces the increased mortality risk of these patients.

    Migration fractionation diagnosis is complicated in rifted basins where migration distance is generally short and lateral migration in sandy beds and vertical migration along faults are co-existed. Quantitative data from GC-MS analysis makes it possible to distinguish lateral and vertical migration effects. Oils discovered from the Jiaolige oilfield, eastern Lujiapu Depression are derived from single source rock with similar maturity, which is an ideal case to study the migration fractionation effects. Compositional differences among oils are largely caused by the migration fractionation either laterally in sand beds or vertically along the faults. Subtle maturity differences are assessed by the classic saturated hydrocarbon parameters which have certain influence on nitrogen compounds. In a certain maturity range, the ratios of shield and semi-shield isomers to the exposed isomers of alkylcarbazoles change with maturity in an opposite direction with migration fractionation, which may conceal the migration influence. However, migration and maturation have the same effects on absolute concentrations of aikylated carbazoles and benzocarhazole [a]/([a]+[c]) ratios, which provides an ideal tool for migration direction assessment. Continuous variations among different samples reflect increased migration distance in sandy beds, while abrupt changes may indicate the change of migration conduit systems. Integrated both geochemical interpretation and geological constrains, not only migration direction can be determined, but also the conduit systems through the sandy beds or the. faults can be recognized.

    Hopelessness, depression and impulsivity all contribute to the development of suicidal ideation in patients with major depressive disorder, but the pathway of these factors to suicidal ideation is not clear. This study examined the meditating effect of depression severity on the relationship between hopelessness and suicidal ideation and explored how this mediating effect was moderated by impulsivity. A total of 162 patients with major depressive disorder (MDD) completed a structured clinical diagnostic interview and a battery of scales assessing depression severity, hopelessness, suicidal ideation, and impulsivity. Regression analyses with bootstrapping methods were used to examine the mediating and moderating effects of various risk factors. Mediation analysis revealed a significant indirect effect of hopelessness on suicidal ideation, and the effect was fully mediated through depression severity. On moderation analysis, the moderating effects of the relationship between depression severity and suicidal ideation were significant in both the medium and high impulsivity groups. The present study was limited by the assessment of trait impulsivity and observer-rated depression severity, which might not fully reflect momentary impulsivity and feeling of depression when suicidal ideation occurs. Depression severity plays a mediator role in the relationship between hopelessness and suicidal ideation and this mechanism is contingent on the levels of impulsivity. MDD patients with higher impulsivity appear to be more likely to have suicidal ideations even when they are less depressed. These findings highlight the importance of impulsivity assessment and alleviation of depressive symptoms to prevent suicidality in patients with MDD. Copyright © 2015 Elsevier B.V.

    Full Text Available Several nutrition, food and dietary compounds have been suggested to be involved in the onset and maintenance of depressive disorders and in the severity of depressive symptoms. Nutritional compounds might modulate depression associated biomarkers and parallel the development of depression, obesity and diabetes. In this context, recent studies revealed new mediators of both energy homeostasis and mood changes (i.e. IGF-1, NPY, BDNF, ghrelin, leptin, CCK, GLP-1, AGE, glucose metabolism and microbiota acting in gut brain circuits. In this context several healthy foods such as olive oil, fish, fruits, vegetables, nuts, legumes, poultry, dairy and unprocessed meat have been inversely associated with depression risk and even have been postulated to improve depressive symptoms. In contrast, unhealthy western dietary patterns including the consumption of sweetened beverage, refined food, fried food, processed meat, refined grain, and high fat diary, biscuits, snacking and pastries have been shown to be associated with an increased risk of depression in longitudinal studies. However, it is always difficult to conclude a real prospective causal relationship from these mostly retrospective studies as depressed individuals might also change their eating habits secondarily to their depression. Additionally specific selected nutritional compounds, e.g. calcium, chromium, folate, PUFAs, vitamin D, B12, zinc, magnesium and D-serine have been postulated to be used as ad-on strategies in antidepressant treatment. In this context, dietary and lifestyle interventions may be a desirable, effective, pragmatical and non-stigmatizing prevention and treatment strategy for depression. At last, several medications (pioglitazone, metformin, exenatide, atorvastatin, gram-negative antibiotics, which have traditionally been used to treat metabolic disorders showed a certain potential to treat depression in first randomized controlled clinical trials.

    Background While ‘personalized medicine’ commonly refers to genetic markers or profiles associated with pharmacological treatment response, tailoring treatments to patient preferences and values is equally important. Objective To describe and demonstrate a method to develop ‘values markers,’ or profiles based on the relative importance of attributes of depression treatment. Study Design Discrete choice analysis was used to assess individuals’ relative preferences for features of depression treatment. Preference profiles were developed using latent profile analysis. Patients or Other Participants Eighty-six adults participating in an internet-based discrete choice questionnaire. Main Outcome Measure Participants were presented with two depression scenarios representing mild and severe depression. For each scenario, they were asked to compare 18 choice sets based on the type of medication side effect (nausea, dizziness, and sexual dysfunction) and severity (mild, moderate, and severe); and for counseling frequency (once per week or every other week) and provider setting (the office of a mental health professional, primary care doctor, or spiritual counselor). Results Three profiles were identified: profile 1 was associated with a preference for counseling and an avoidance of medication side effects; profile 2 with an avoidance of strong medication side effects and for receiving counseling in medical settings; and profile 3 with a preference for medication over counseling. When presented with a severe depression scenario, there was a higher prevalence for profile 1 and patients were more likely to prefer mental health over primary care and spiritual settings. Conclusions Values markers may provide a foundation for personalized medicine, and reflect current initiatives emphasizing patient-centered care. Next steps should assess whether values markers are predictive of treatment initiation and adherence. PMID:23420133

    The hopelessness theory of depression [Abramson, L. Y., Metalsky, G. I. & Alloy, L. B. (1989). Hopelessness depression: a theory-based subtype of depression. Psychological Review, 96, 358-372.] postulates that a negative attributional style represents a risk factor for a particular constellation of depressive symptoms, termed 'hopelessness depression'. Four studies tested the relation of negative attributional style to hopelessness depression symptoms versus endogenous depression symptoms. Despite the considerable overlap of hopelessness and endogenous depression symptoms, negative attributional style was more related to the former than the latter, consistent with hopelessness theory.

    Full Text Available Background: Motor imagery is a potential tool to investigate action representation, as it can provide insights into the processes of action planning and preparation. Recent studies suggest that depressed patients present specific impairment in mental rotation. The present study was designed to investigate the influence of unipolar depression on motor imagery ability.Methods: Fourteen right-handed patients meeting DSM-IV criteria for unipolar depression were compared to fourteen matched healthy controls. Imagery ability was accessed by the timing correspondence between executed and imagined movements during a pointing task, involving strong spatiotemporal constraints (speed/accuracy trade off paradigm.Results: Compared to controls, depressed patients showed marked motor slowing on both actual and imagined movements. Furthermore, we observed greater temporal discrepancies between actual and mental movements in depressed patients than in healthy controls. Lastly, depressed patients modulated, to some extent, mental movement durations according to the difficulty of the task, but this modulation was not as strong as that of healthy subjects.Conclusion: These results suggest that unipolar depression significantly affects the higher stages of action planning and point out a selective decline of motor prediction.

    Full Text Available Introduction: Aging is a natural process in individuals. Most of the elderly have problems in dealing with this natural process. Lost of occupation, friends and loneliness may result in depression in this age group. Cognitive therapy changes pessimistic idea, unrealistic hopes and excessive self evaluation may result and justify depression. Cognitive therapy may help elderly to recognize the problem in life, to develop positive objective of life and to create more positive personality. The aimed of this study was to analyze the effect of cognitive therapy to reduce the level of depression. Method: This study was used a pre experimental pre post test design. Sample were 10 elderly people who met to the inclusion criteria. The independent variable was cognitive therapy and dependent variable was the level of depression in elderly. Data were collected by using Geriatric Depression Scale (GDS 15, then analyzed by using Wilcoxon Signed Rank Test with significance levelα≤0.05. Result: The result showed that cognitive therapy has an effect on reducing depression with significance level p=0.005. Discussion: It can be concluded that cognitive therapy was effective in reducing depression level in elderly. Further studies are recommended to analyze the effect of cognitive therapy on decreasing anxiety in elderly by measuring cathecolamin.

    Full Text Available OBJECTIVE To estimate the prevalence of depressive symptoms among institutionalized elderly individuals and to analyze factors associated with this condition. METHODS This was a cross-sectional study involving 462 individuals aged 60 or older, residents in long stay institutions in four Brazilian municipalities. The dependent variable was assessed using the 15-item Geriatric Depression Scale. Poisson’s regression was used to evaluate associations with co-variables. We investigated which variables were most relevant in terms of presence of depressive symptoms within the studied context through factor analysis. RESULTS Prevalence of depressive symptoms was 48.7%. The variables associated with depressive symptoms were: regular/bad/very bad self-rated health; comorbidities; hospitalizations; and lack of friends in the institution. Five components accounted for 49.2% of total variance of the sample: functioning, social support, sensory deficiency, institutionalization and health conditions. In the factor analysis, functionality and social support were the components which explained a large part of observed variance. CONCLUSIONS A high prevalence of depressive symptoms, with significant variation in distribution, was observed. Such results emphasize the importance of health conditions and functioning for institutionalized older individuals developing depression. They also point to the importance of providing opportunities for interaction among institutionalized individuals.

    Objective: To investigate the depression status of patients with sexually transmitted diseases (STDs).Methods: The depression status of fifty-one hospitalized STD patients was evaluated in a randomized control study using Zung's Quantitative Table. 18 healthy control patients with similar demographic backgrounds were randomly chosen as controls. Patients with scores above or equal to 40 were considered to be suffering from depression.Results: The prevalence rate of depression in the patient group was obviously higher than that of in the control (X2=16.456,P<0.01). Prevalence of depression was found to be significantly related to occupation (P<0.05). Though the prevalence was not found to differ significantly between those with a treatment course less than 2 months and those with one longer or equal to 2 months (X2=0.041, P>0.05), the mean depression scores of the former group were significantly higher than those of the latter (P<0.01). No significant differences were found between new versus relapsing disease, married versus non-married, male versus female, or differing educational backgrounds.Conclusion: STD patients showed significant prevalence of depression.

  1. Testosterone and Depression

    2010-12-01

    Full Text Available Androgens have various effects on human body and mood. Testosterone, a hormone mainly secreted from testes and adrenals, is one of the most potent androgens. Multiple studies have found that testosterone plays a role in regulating sexual activity, libido, social behaviors, aggression, cognitive functions, sleep control and well-being in men and women. Testosterone deficiency in hypogonadic or elderly men leads to neuropsychiatric problems, such as fatigue, loss of libido, irritability, insomnia and depressive mood. Testosterone replacement therapy consistently reverses these sequel in men. On the other hand, hyperandrogenic states in women are related to aggression and antisocial behavior, which might lead to depressive mood. Low testosterone levels may also result in depression among oophorectomized women. Because of such effects, a relationship between testosterone and depression has long been an issue of speculation, but yet very few studies have addressed this relation. Along with clinical studies, experimental and epidemiological studies show that testosterone is related to depression in men and women. But studies of testosterone concentrations in depression have yielded inconsistent results reporting low as well as high testosterone levels associated with depression. In this article, the physiological and psychological effects of testosterone and evidence regarding its relationship to depressive disorders and possible gender differences have been reviewed.

  2. Depression in older adults.

    2009-01-01

    Depression is less prevalent among older adults than among younger adults, but it can have serious consequences. More than half of cases represent a first onset in later life. Although suicide rates in the elderly are declining, they are still higher than in younger adults and are more closely associated with depression. Depressed older adults are less likely to endorse affective symptoms and more likely to display cognitive changes, somatic symptoms, and loss of interest than are depressed younger adults. Risk factors leading to the development of late-life depression likely comprise complex interactions among genetic vulnerabilities, cognitive diathesis, age-associated neurobiological changes, and stressful events. Insomnia is an often overlooked risk factor for late-life depression. We suggest that a common pathway to depression in older adults, regardless of which predisposing risks are most prominent, may be curtailment of daily activities. Accompanying self-critical thinking may exacerbate and maintain a depressed state. Offsetting the increasing prevalence of certain risk factors in late life are age-related increases in psychological resilience. Other protective factors include higher education and socioeconomic status, engagement in valued activities, and religious or spiritual involvement. Treatments including behavioral therapy, cognitive-behavioral therapy, cognitive bibliotherapy, problem-solving therapy, brief psychodynamic therapy, and life review/reminiscence therapy are effective but are too infrequently used with older adults. Preventive interventions including education for individuals with chronic illness, behavioral activation, cognitive restructuring, problem-solving skills training, group support, and life review have also received support.

    The objective of this at issue paper is the analysis of published data in correlation with the results of own research on the potential role of ionizing radiation in the genesis of depressive disorders. Depression is one of the most significant and long-term effect of the atomic bombings, nuclear testing and radiation emergences. The participants of the accident at the Chornobyl nuclear power plant increased prevalence of depression (18.0% and 13.1% in controls) and suicide rates. Depression is mainly observed in the structure of an organic mental disorder against cerebrovascular disease. The clinical pattern is dominated by asthenoadynamic and asthenoapathetic depression. Depressive disorders in radiation emergencies are multifactorial, that is the result of exposure to the complex psychogenic and radiological accident's factors, impact of traditional risk factors, somatic and neurological diseases, genetic predisposition, predisposition, etc. At the same time, exposure to ionizing radiation is a factor in the genesis of depression. This impact can be direct (to the Central Nervous System), and indirectly through the somatic and neurological abnormalities (multiorgan dysfunction) as well as by a variety of pathogenic mechanisms of ionizing radiation on the brain that have been discovered recently. It is strongly necessary analytical clinical and epidemiological studies with verification of depression and evidence-based establishment of the role of radiation and non-radiation risk factors.

    Deficits in pro-social cooperation are common in many individuals with mental illnesses such as depression. For decades, researchers have used economic game paradigms to compare cross-cultural cooperative behavior. However, research using economic games to assess cooperative behavior in clinical populations is in the early stages. We hypothesized that individuals with greater depressive symptoms would struggle to maintain reciprocity in iterative games, but not in single-iteration games measuring personal values. Participants (n=41) played four computer-based economic games (prisoner's dilemma, the public goods game, the ultimatum game, and the trust game) measuring different aspects of cooperation. Participants completed the Depression Anxiety and Stress Scale (DASS) and other measures of personality and demographics. Analyses assessed the relationships between game performance and psychological distress as measured by the DASS. Significant correlations were found between game performance and depressive symptoms, but not symptoms of anxiety or stress. Performance in the prisoner's dilemma and public goods game was significantly related to depression in a linear regression even when known associations with depressive affect such as age, gender, race, education, marital status, and neuroticism were controlled for. Depressive symptoms were associated with an inability to sustain reciprocal cooperation. Participants showed the predicted deficits in cooperation in these economic games. Economic games show the potential for assessing the social deficits associated with depressive symptoms. © 2013 Elsevier B.V. All rights reserved.

  12. SWAT Modeling for Depression-Dominated Areas: How Do Depressions Manipulate Hydrologic Modeling?

    Full Text Available Modeling hydrologic processes for depression-dominated areas such as the North American Prairie Pothole Region is complex and reliant on a clear understanding of dynamic filling-spilling-merging-splitting processes of numerous depressions over the surface. Puddles are spatially distributed over a watershed and their sizes, storages, and interactions vary over time. However, most hydrologic models fail to account for these dynamic processes. Like other traditional methods, depressions are filled as a required preprocessing step in the Soil and Water Assessment Tool (SWAT. The objective of this study was to facilitate hydrologic modeling for depression-dominated areas by coupling SWAT with a Puddle Delineation (PD algorithm. In the coupled PD-SWAT model, the PD algorithm was utilized to quantify topographic details, including the characteristics, distribution, and hierarchical relationships of depressions, which were incorporated into SWAT at the hydrologic response unit (HRU scale. The new PD-SWAT model was tested for a large watershed in North Dakota under real precipitation events. In addition, hydrologic modeling of a small watershed was conducted under two extreme high and low synthetic precipitation conditions. In particular, the PD-SWAT was compared against the regular SWAT based on depressionless DEMs. The impact of depressions on the hydrologic modeling of the large and small watersheds was evaluated. The simulation results for the large watershed indicated that SWAT systematically overestimated the outlet discharge, which can be attributed to the failure to account for the hydrologic effects of depressions. It was found from the PD-SWAT modeling results that at the HRU scale surface runoff initiation was significantly delayed due to the threshold control of depressions. Under the high precipitation scenario, depressions increased the surface runoff peak. However, the low precipitation scenario could not fully fill depressions to reach

    Concerns about the adequate assessment and treatment of adolescent depression have been in the forefront of pediatric mental health literature in the recent past. While quantitative studies have provided valuable information, the voice of the adolescent has been lacking in the development of theory and treatment of this prevalent disorder. Using approach, a metasynthesis of six qualitative studies was conducted. This process revealed six themes that outline the course of adolescents who struggle with depression: (a) beyond the blues, (b) spiraling down and within, (c) breaking points, (d) seeing and being seen, (e) seeking solutions, and (f) taking control. Knowledge of the experience of adolescent depression will aid practitioners in recognition and early intervention for the increasing number of adolescents suffering with depression, as well as guide educational initiatives to provide needed information on the symptoms of depression and available resources for getting help.

    Suicide is a major public health problem and the number of suicide victims has exceeded 30,000 a year since 1998 in Japan. The rates of depression are extremely high in suicide victims. Social and environmental factors, such as the slow recovery of Japanese economy, could have a strong effect on depression and suicide, especially in middle-aged men. To reduce the number of suicide victims, we need to use both population-based and high-risk approaches, targeting individuals with high psychological and socioeconomic risks of suicide, especially depressed patients. On the other hand, the role of antidepressants in suicide prevention is a major question given the high prevalence of both depression and depression-related suicidality. Because treatment and prevention of suicide are complex and encompass many factors, success will need multi-sector collaboration.

    Myocardial infarction (MI) is a severe life event that is accompanied by an increased risk of depression. Mounting evidence suggests that post-MI depression is associated with adverse outcomes, but the underlying mechanisms of this association remain unclear, and no previous studies have examined...... whether the mental burden of MI is so heavy that it increases the risk of suicide. Although post-MI depression is common and burdensome, the condition remains under-recognised and under-treated. The development of new strategies to improve the quality of care for people with post-MI depression requires...... thorough understanding of the mechanisms that influence the prognosis as well as knowledge of the present care provided. The purpose of this PhD thesis is accordingly subdivided into four specific aims: 1. To estimate the prevalence of depression in people with MI after three months, and to estimate...

    In this paper, I propose that depression is a political phenomenon insofar as it has political sources and consequences. I then investigate one aspect of this argument—whether depression reduces participation. I hypothesize that individuals with depression lack the motivation and physical capacity to vote and engage in other forms of political participation due to somatic problems and feelings of hopelessness and apathy. Moreover, I examine how depression in adolescence can have downstream consequences for participation in young adulthood. The analyses, using both cross-sectional and longitudinal data, show that voter turnout and other forms of participation decrease as the severity of depressed mood increases. These findings are discussed in light of disability rights and potential efforts to boost participation among this group. PMID:26924857

    The indication for psychoanalysis in severe depression is not clear. And yet, demands for this type of intervention are increasing, despite the absence of any form of consensus on the subject. Freud considered depression as a failure of analytical efforts and, based on this observation, revised his theory, in particular to include the notions of narcissism and the death drive. Many analysts have been reluctant to follow his teachings on this last point and provide depressed patients with analytical-type therapies aimed at restoring narcissism. Melanie Klein pushed Freud's ideas about depression even further and brought such therapies back to the heart of analytical practice. Jacques Lacan took the debate to another level by proposing an overhaul of the principles on which analysis has been based. Today, while following certain precautionary rules, true psychoanalyses can be proposed to patients with severe depression, whether of the bipolar, recurring or even neurotic type that can reach this level of severity.

    Full Text Available Objectives: Epidemiologic data suggests an association between obesity and depression. However, a limited number of studies have investigated the prevalence of psychiatric symptoms among obese patients without a psychiatric diagnosis. The objective of this study was to determine psychiatric diagnosis in patients with obesity who applied to the endocrinology department and to determine the pattern of the depression and anxiety symptom levels in obese patients without a psychiatric diagnosis.Materials and Methods: 62 patients with obesity (obesity group and 27 control subjects (control group attending the endocrinology outpatient clinic were included in the study. Body mass index was calculated and diagnostic psychiatric assessment carried out for all patients. All participants were evaluated using the Hamilton Depression Rating Scale [HAM-D] and Hamilton Anxiety Rating Scale [HAM-A].Results: Total scores obtained both from HAM-D and HAM-A were significantly greater in the obesity group than in the control group. The most common psychiatric diagnose among obese patients was depression. Nearly more than half of the obese patients without any psychiatric diagnosis marked one of the HAM-D items which describes depressed mood, guilt feeling, somatic anxiety, work and activity loss and general somatic symptoms as well as the items within the HAM-A scale which describes anxious mood, tension, cognitive difficulties, insomnia, depressed mood, somatic anxiety, cardiovascular, respiratory, gastrointestinal and autonomic symptoms.Conclusion: Most common psychiatric diagnosis in patients with obesity was major depressive disorder. Obese patients who have not been diagnosed with any psychiatric disorder also show certain anxiety and depressive symptoms. The presence of anxiety and depressive symptoms in patients having any psychiatric disorder may be due to the psychosocial effects of obesity and these symptoms should be followed up in obese patients so that

    Full Text Available Background: Aging has become greatest challenge globally. In developing countries including India elderly population (persons aged 60 years and above is projected to outpace the rich world resulting in 50-80 percent of them expected to be staying in resource constraint countries. By 2050 of the total population more than 20 percent will be elderly. Depressive illness associated with dementia is one of the important problems in elderly. With increase in longevity there will be sharp rise in old age dependency ratio which can drain the resources in any country due to expenditure on health, social security and education. Aim & Objectives: The present study was carried out to assess the extent of degree of depression in elderly and study the associated factors like economic dependency. Material and Methods: Randomly selected subjects were administered the questionnaire of Geriatric Depression Scale (GDS, in the Geriatric Clinic of a tertiary care hospital, to categorize them based on the scores, into mild, moderate and severe. Some of the factors were studied and analysed to nd out their association with depression like working status, socioeconomic status and economic dependency. Results: Proportion of elderly having depression was 52.4% with females outnumbering males. Depression seems to be more in those elderly who were not working, were from low socioeconomic status and not having pension as 38.6% who had no pension were depressed. Moderate to severe depression was more in economically dependent (20% as compared to those who were independent nancially. Conclusion: Economic dependency seems to be important associated factor responsible for depression in elderly along with other factors like socioeconomic status, pension status etc. Implementation of adequate health services and social security system is needed to prevent the marginalization of elderly.

    Full Text Available Abstract Background Research suggests that depressive disorders exist on a continuum, with subthreshold symptoms causing considerable population burden and increasing individual risk of developing major depressive disorder. An alternative strategy to professional treatment of subthreshold depression is population promotion of effective self-help interventions that can be easily applied by an individual without professional guidance. The evidence for self-help interventions for depressive symptoms is reviewed in the present work, with the aim of identifying promising interventions that could inform future health promotion campaigns or stimulate further research. Methods A literature search for randomised controlled trials investigating self-help interventions for depressive disorders or depressive symptoms was performed using PubMed, PsycINFO and the Cochrane Database of Systematic Reviews. Reference lists and citations of included studies were also checked. Studies were grouped into those involving participants with depressive disorders or a high level of depressive symptoms, or non-clinically depressed participants not selected for depression. A number of exclusion criteria were applied, including trials with small sample sizes and where the intervention was adjunctive to antidepressants or psychotherapy. Results The majority of interventions searched had no relevant evidence to review. Of the 38 interventions reviewed, the ones with the best evidence of efficacy in depressive disorders were S-adenosylmethionine, St John's wort, bibliotherapy, computerised interventions, distraction, relaxation training, exercise, pleasant activities, sleep deprivation, and light therapy. A number of other interventions showed promise but had received less research attention. Research in non-clinical samples indicated immediate beneficial effects on depressed mood for distraction, exercise, humour, music, negative air ionisation, and singing; while potential

    Full Text Available Background: India is in the process of rapid demographic progression of increased life expectancy and aging with geriatric population of 7.2 percent which is estimated to rise to 20 percent in 2050. With increasing geriatric population elderly with dementia and associated depressive illness are expected to rise in number to almost an epidemic. Among the morbidity encountered in elderly, depressive disorders are common. Aim & Objectives: The present study was conducted with the objective to assess the extent and degree of depression in elderly, and study some correlates associated with depression in them. Material & Methods: The study was carried out at geriatric clinic of Dr. D. Y. Patil Medical College, Pune under the guidance of department of community medicine. Methodology:The randomly selected elderly above the age of 60 years attending the clinic and willing to participate in study were administered the questionnaire of Geriatric Depression Scale (GDS, scores were given, based on which the subjects were categorized as mild, moderate and severe. Those with score >5 were considered as suggestive of depression and some factors studied were analysed to find out their association with depression. Results: It was revealed that the proportion of elderly having depression was 52.4% with 84.6% of depressed in age group of 76-80 years. Moderate to severe type was more commonly seen in illiterate; however some degree of depression was present in all elderly irrespective of literacy status. Moderate to severe type was seen more commonly in elderly living in nuclear families (23.8%, and living alone (33.3%. Thus more than half of elderly studied were having depression, and it was observed that as the age advanced the degree of depression significantly increased. Some of the factors studied like low education status, poor economic status, nuclear family status, single status, loneliness, were associated with depression. The GDS Scale can be considered as

    Full Text Available Background. Depression is one of the most common mental disorders worldwide and is the second leading cause of disability and major contributor to suicide. Methods. Community based cross-sectional study was conducted among 779 adults residing in Northwest Ethiopia. Multistage cluster sampling technique was used to select study participants. Depression was measured by Patient Health Questionnaire (PHQ-9. Bivariate as well as multivariate logistic regressions were used to identify associated factors. p value of < 0.05 was considered statistically significant. Result. The prevalence of depression was 17.5%, where 10.7% of patients were with mild depression, 4.2% were with moderate depression, 1.9% were with moderately severe depression, and 0.6% had severe depression. Being female, age of 55 years and above, poor social support, having a comorbidity medical illness, current tobacco smoking, and living alone were significantly associated with depression. Conclusion and Recommendation. The prevalence of depression in Ethiopia is as common as the other lower and middle income countries. Female gender, being currently not married, poor social support, low wealth index, tobacco smoking, older age, having comorbid illness, and living alone were significantly associated with depression. So, depression is a significant public health problem that requires a great emphasis and some factors like smoking habit are modifiable.

    Full Text Available Background The most common symptom in early menopausal women is depression. Depression is a type of chronic disease that impacts on postmenopausal women’s life. Social support plays a protective role for women and enables them to solve their life problems and thus, feel less depressed. Objectives We assessed depression as a chronic disease and evaluated the association between perceived social support and depression in postmenopausal women. Patients and Methods This correlation-analytic study was conducted on 321 postmenopausal women using 2-stage cluster sampling in Ahvaz in 2014. Data collecting instruments were comprised of a demographic questionnaire, a depression scale (Beck Depression Inventory-II, and a social support questionnaire (PRQ 85-Part 2. Data analysis was done using SPSS, version 20. The Spearman correlation coefficient was used to evaluate the relationship between perceived social support and depression, and the χ2 test was employed to assess the relationship between perceived social support and demographic characteristics. Results The Spearman correlation test revealed a significant reverse relationship between perceived social support and depression (r = -0.468; P = 0.001. There were significant relationships between perceived social support and some personal variables such as marital status, education level, and job status (P 0.05. Conclusions We found a reverse relationship between perceived social support and depression in postmenopausal women. Raising awareness in society apropos the relationship between social support and depression in postmenopausal women can enhance their quality of life.

    Adolescence is an important period for initiation of smoking and manifestation of depression, which are often comorbid. Researchers have examined associations between depressive symptoms and smoking to elucidate whether those with increased depressive symptoms smoke more to self-medicate, whether those who smoke experience increased subsequent depressive symptoms, or both. Collectively, there have been mixed findings; however, studies have been limited by (1) cross-sectional or short-term longitudinal data or (2) the use of methods that test associations, or only one direction in the associations, rather than a fully-reciprocal model to examine directionality. This study examined the associations between smoking and depressive symptoms in a sample of adolescent girls using latent dual change scores to model (1) the effect of smoking on change in depressive symptoms, and simultaneously (2) the effect of depressive symptoms on change in smoking across ages 11-20. Data were from a cohort-sequential prospective longitudinal study (N = 262). Girls were enrolled by age cohort (11, 13, 15, and 17 years) and were primarily White (61 %) or African American (31 %). Data were restructured by age. Every 6 months, girls reported depressive symptoms and cigarette use. Results indicated that controlling for sociodemographic characteristics, higher levels of smoking predicted a greater increase in depressive symptoms across adolescence. These findings suggest that a higher level of cigarette smoking does contribute to more depressive symptoms, which has implications for prevention of depression and for intervention and future research.

    Full Text Available Objectives. Adolescence is associated with increased depressive symptoms and decreased aerobic exercise, yet the relationship between exercise and clinical depression among adolescents requires further examination. This study assessed the feasibility of a 12-week intervention designed to increase exercise for adolescents with depressive disorders: Will a teenager with depression exercise? Methods. Participants were 13 adolescents with depression reporting low levels of aerobic exercise. They completed a 12-week intervention (15 supervised exercise sessions and 21 independent sessions. Exercise was measured through the aerobic exercise Questionnaire, actigraphy, and heart-rate monitoring. Depression was measured with the Children’s Depression Rating Scale, Revised, and Quick Inventory of Depressive Symptomatology, Self-Report. Results. All participants who started the intervention completed the protocol, attending all supervised exercise sessions. Actigraphy verified 81% adherence to the protocol’s independent sessions. Analysis of secondary outcomes showed a significant increase in exercise levels and a significant decrease in depression severity. Initially, ten participants were overweight or obese, and three were healthy weight. After 12 weeks of exercise, the number of participants in the healthy-weight category doubled. Conclusions. Adolescents suffering from depression can complete a rigorous protocol requiring structured increases in aerobic exercise. Participants showed significant increases in exercise, and significant decreases in depressive symptoms.

    Perez, S; Junod, A

    1998-01-01

    We now have a better knowledge of the specific features of depression in sub-Saharan Africa. Anthropologically speaking, the Western model is irrelevant. Depression in sub-Saharan Africa involves the relationship of the subject to himself or others in a mode specific to African cultures. Ignoring this fact can lead to simplistic ethnocentrism. From a clinical standpoint, depressive illness characterized by somatic manifestations, delusions of persecution, and anxiety are increasingly uncommon. As African societies modernize, these traditional forms are being gradually supplanted by states with symptoms and prognoses more like those observed in industrialized countries. Hybrid depressive syndromes are now the most widespread. Epidemiologically the notion widely held only a few decades ago that depression is a rare occurrence in Africa has now been dispelled. Many studies have been conducted to determine the exact incidence, age distribution, and sex ratio but more precise data is still needed. This investigation will require improvement in screening and diagnostic methods which must be not only suitable for clinical use but also adaptable to local conditions. This is also true with regard to management which has the same goals as anywhere else in the world. Treatment facilities are different in urban and rural areas but care is often dispensed in unconventional settings and may be combined with traditional methods. Drug availability is limited by problems involving supply and cost. This explains why electro-convulsive therapy which was introduced into sub-Saharan Africa long ago still plays a major role in the treatment of depression.

    Full Text Available Patients with bipolar disorder spend more time in a depressed than manic state, even with individualized treatment. To date, bipolar depression is often misdiagnosed and ineffectively managed both for acute episodes and residual symptoms. This review attempts to summarize the current status of available treatment strategies in the treatment of bipolar depression. For acute and prophylactic treatment, a substantial body of evidence supports the antidepressive efficacy of lithium for bipolar disorders and its antisuicidal effects. Among numerous anticonvulsants with mood-stabilizing properties, valproate and lamotrigine could be first-line options for bipolar depression. Due to receptor profile, mood-stabilizing properties of second-generation antipsychotics have been explored, and up to date, quetiapine and olanzapine appear to be a reasonable option for bipolar depression. The usefulness of antidepressants in bipolar depression is still controversial. Current guidelines generally recommend the cautious antidepressant use in combination with mood stabilizers to reduce the risk of mood elevation or cycle acceleration. Results from clinical trials on psychosocial intervention are promising, especially when integrated with pharmacotherapy. Most patients with bipolar depression need individualized and combined treatment, although the published evidence on this type of treatment strategy is limited. Future studies on the utility of currently available agents and modalities including psychosocial intervention are required.

    2007-11-01

    Depression and erectile dysfunction (ED) clearly are associated. Although urologists and psychiatrists have long recognized that antidepressant medications affect erectile function negatively, the interplay between the two conditions remains underappreciated. Psychiatrists may be reluctant to question a patient in detail about ED, and urologists seldom perform a formal assessment of the presence of depression in patients who have ED. This article gives a quick overview of the relationship between these two conditions and provides the clinician with the knowledge required to effectively manage ED with comorbid depression.

    Full Text Available Abstract Background In schizophrenia and major depressive disorder, anhedonia (a loss of capacity to feel pleasure had differently been considered as a premorbid personological trait or as a main symptom of their clinical picture. The aims of this study were to examine the pathological features of anhedonia in schizophrenic and depressed patients, and to investigate its clinical relations with general psychopathology (negative, positive, and depressive dimensions. Methods A total of 145 patients (80 schizophrenics and 65 depressed subjects were assessed using the Physical Anhedonia Scale and the Social Anhedonia Scale (PAS and SAS, respectively, the Scales for the Assessment of Positive and Negative Symptoms (SAPS and SANS, respectively, the Calgary Depression Scale for Schizophrenics (CDSS, and the Hamilton Depression Rating Scale (HDRS. The statistical analysis was performed in two steps. First, the schizophrenic and depressed samples were dichotomised into 'anhedonic' and 'normal hedonic' subgroups (according to the 'double (PAS/SAS cut-off' and were compared on the general psychopathology scores using the Mann-Whitney Z test. Subsequently, for the total schizophrenic and depressed samples, Spearman correlations were calculated to examine the relation between anhedonia ratings and the other psychopathological parameters. Results In the schizophrenic sample, anhedonia reached high significant levels only in 45% of patients (n = 36. This 'anhedonic' subgroup was distinguished by high scores in the disorganisation and negative dimensions. Positive correlations of anhedonia with disorganised and negative symptoms were also been detected. In the depressed sample, anhedonia reached high significant levels in only 36.9% of subjects (n = 24. This 'anhedonic' subgroup as distinguished by high scores in the depression severity and negative dimensions. Positive correlations of anhedonia with depressive and negative symptoms were also been detected

    Objective Transactional models have been used to explain the relationship between maternal depression and child behavioral problems; however, few studies have examined transactional models for maternal depression and adolescent depression and anxiety. Method Using an autoregressive cross-lagged analysis, we examined the longitudinal association between maternal and adolescent depression to determine the extent to which maternal depression influences adolescent depression and anxiety, and vice versa, over the course of a four-year period. Participants were a community sample of 277 mother-adolescent dyads with offspring aged 10–14 at the first year used in the analyses (43.7% female; 35% African American, 2.9% Hispanic/Latino). Depressive symptoms were assessed using maternal self-report (Center for Epidemiological Studies-Depression Scale [CESD]; Radloff, 1977), and adolescent depression and anxiety were assessed by self-report (Revised Child Anxiety and Depression Scale [RCADS]; Chorpita, Yim, Moffitt, Umemoto, & Francis, 2000). Results The final model, χ2 (14) = 23.74, p= .05; TLI= .97; CFI= .98; RMSEA= .05, indicated that maternal depression was significantly associated with adolescent depression two years later. Interestingly, adolescent depression did not significantly predict maternal depression, and the association between maternal and adolescent depression was not moderated by gender, age, or ethnicity. The association between maternal depression and adolescent anxiety was weaker than that observed for adolescent depression. Conclusions Results suggest that the transaction model of maternal depression may not extend to adolescent depression and anxiety. Furthermore, maternal depression can have an enduring effect on adolescent depression and continued research and clinical monitoring over extended periods of time is warranted. PMID:24702257

    Full Text Available BackgroundThe degree by which depressive symptoms and clinical depression reflect each other may vary across populations. The present study compared Blacks and Whites for the magnitude of the cross-sectional associations between various domains of depressive symptoms and endorsement of clinical disorders of depression. MethodsData came from the National Survey of American Life (NSAL, 2001–2003. We included 3,570 Black (African Americans, and 891 Non-Hispanic Whites. Predictors were positive affect, negative affect, and interpersonal problems measured using the 12-item Center for Epidemiologic Studies Depression Scale (CES-D. Outcomes were lifetime MDD, lifetime MDE, 12 month MDE, 30 days MDE, and 30 days MDDH based on the Composite International Diagnostic Interview (CIDI. Logistic regression models were applied in the pooled sample, as well as Blacks and Whites.ResultsRegarding CES-D, Blacks had lower total scores, positive affect, negative affect, and interpersonal problems compared to Whites (p < 0.05 for all comparisons. Blacks also had lower odds of meeting criteria for lifetime MDD and MDE, 12 month MDE, and 30 days MDE and MDDH (p < 0.05 for all comparisons. For most depressive diagnoses, ethnicity showed a positive and significant interaction with the negative affect and interpersonal domains, suggesting stronger associations for Blacks compared to Whites. CES-D total and CES-D positive affect did not interact with ethnicity on CIDI based diagnoses.ConclusionStronger associations between multiple domains of depressive symptoms and clinical MDD may be due to higher severity of depression among Blacks, when they endorse the disorder. This finding may explain some of previously observed ethnic differences in social, psychological, and medical correlates of depressive symptoms and clinical depression in the general population as well as clinical settings.

    Full Text Available Background: Depression has been found to be associated with cardiovascular diseases in various studies done in different parts of the world. Whether depression really develops after an attack of acute myocardial infarction (AMI in hospitalised patients was not evaluated in this region of our country prior to the current work. Aim: To evaluate the prevalence of depression and impact of depression in AMI patients during the period of hospitalisation. Materials and method: Patients were recruited for the study after fulfilling the selection criteria and who had documented AMI within four to five days of hospitalisation. Informed consent of the patient and ethical committee clearance was obtained. To collect data semi-structured interview schedule was used. Assamese versions of 21 self-report items Beck Depression Inventory (BDI and observer-rated 17 items Hamilton Rating Scale for Depression (HAM-D were administered to 50 AMI patients. Data were analysed with chi-square test, Pearson coefficient of correlation, and student t test wherever applicable. p-value<0.05 was considered test of significance in this study. Result: Fifty cases of AMI were evaluated from August 2007 to July 2008. Thirty six per cent of AMI patients and 34% of AMI patients were found to have depression as per BDI and HAM-D scales respectively. Depression has an impact on duration of hospital stay significantly (p<0.019 but not on gender difference (p=0.089. Correlation of mean scores of both HAM-D and BDI scales was done by Pearson coefficient of correlation and was found to be significant at .01 level. Conclusion: Depression was found to be high in AMI patients during the period of hospitalisation in both the depression rating scales and it has an impact on prognosis of the patients.

    Several works show an association between depression and the occurence of a first myocardial infarction. Depression after myocardial infarction seems to be a marker of poorer outcome, regardless of other risk factors or severity of the myocardial infarction. Dysautonomia and alteration of platelet activation are a few physiopathological changes shared by both affections, through which they might be related. Treatment of depression is not associated with better cardiovascular outcome, but selective serotonin reuptake inhibitors have been shown safe and efficient among patients with coronary heart disease. Cognitivo-comportemental approach and cardiovascular rehabilitation program after myocardial infarction also play a role in improving quality of life of the depressed patient with coronary heart disease.

    2009-04-01

    Chronic stress, by initiating changes in the hypothalamic-pituitary-adrenal (HPA) axis and the immune system, acts as a trigger for anxiety and depression. There is experimental and clinical evidence that the rise in the concentration of pro-inflammatory cytokines and glucocorticoids, which occurs in a chronically stressful situation and also in depression, contribute to the behavioural changes associated with depression. A defect in serotonergic function is associated with these hormonal and immune changes. Neurodegenerative changes in the hippocampus, prefrontal cortex and amygdalae are the frequent outcome of the changes in the HPA axis and the immune system. Such changes may provide evidence for the link between chronic depression and dementia in later life.

  10. RAPID TEST METHOD FOR EVALUATION OF ANTIFREEZE ADDITIVE EFFICIENCY

    2015-01-01

    Full Text Available Usage of chemical additives while executing concrete works at negative temperatures is considered as a convenient and economical method. Range of the used antifreeze additives is rather wide. A great number of new additives are advertised but their characteristics have not been practically studied. Evaluation of the antifreeze additive efficiency is unfortunately rather long process and it does not provide comprehensive data on concrete structure formation processes. Due to this development of rapid and comprehensive methodology for construction companies is urgently required.Freezing processes of antifreeze additive aqueous solutions and hardening of cement paste with them have been investigated in the paper. The paper proposes a methodology for determination of freezing point for aqueous solutions of chemical additives of various applications. Identity of  freezing point for a chemical additive aqueous solution and cement paste with an equal concentration of the additive in the paste pore fluid has been determined while taking  calcium nitrate and sodium formate additives as an example. The paper demonstrates the possibility to evaluate efficiency of antifreeze additive action on the basis of kinetics in temperature changes of the cement paste with additives by its consecutive freezing and defrosting.  A methodology for operational evaluation in the field of chemical additive application for concreting items at negative temperatures has been offered in the paper.  The methodology does not require  deficient and expensive test-equipment. It can be applied at ordinary construction companies and it is comprehensible for personnel of low-qualification.  The paper shows the possibility to develop an original methodology for designing concrete structure which is based on operating efficiency determinations  for single and integrated antifreeze additives.

    Seven million American women are depressed, and 40 million Americans, primarily women, have been labeled as codependent. This study aimed to identify the prevalence of codependency in women undergoing treatment for depression, examine the relationship between codependency and depression, and determine which of the symptoms of codependency are most highly predictive of depression scores. Depression and codependency were measured in a sample of 105 depressed women by using the Beck Depression Inventory and the Codependency Assessment Tool. Descriptive statistics, Pearson's Product Moment Correlation, and multiple regression were used for analysis. Of these depressed women, 36% were moderately to severely codependent. Depression and codependency were strongly related, with the significant gamma = .92 (P codependency subscales, Low Self-Worth and Hiding Self correlate most strongly with depression; Other Focus/Self-Neglect added the least-independent--explanatory power. Thus, future research should be directed toward the relationship of codependency to power, alienation of self, and personality disorders.

    2014-07-01

    Full Text Available Introduction: Depression has been found to increase the risk of mortality in patients with coronary artery disease through a mechanism of changing cardiac autonomic tone which is reflected by alteration of heart rate variability indices. This study investigated whether such mechanism existed in firefighters who were at high risk of depression and sudden cardiac death. Methods and results: In total, 107 firefighters were recruited. All completed Beck Depression Inventory and underwent 24-h ambulatory electrocardiographic monitoring. The root-mean-square of successive differences, standard deviation of all normal-to-normal intervals index, and the percentage of differences between adjacent normal-to-normal intervals >50 ms were significantly lower in depressed than in non-depressed firefighters after controlling for hypertension, age, and body mass index (40.1 ± 18.8 vs 62.5 ± 77.4, p < 0.01; 63.0 ± 19.2 vs 72.1 ± 34.8, p < 0.01; 8.4 ± 7.2 vs 12.7 ± 10.9, p < 0.01, respectively. Conclusion: Decreased vagal tone is a possible mechanism linking depression and sudden cardiac death in firefighters.

    Full Text Available OBJECTIVE To analyze the association between unintended pregnancy and postpartum depression. METHODS This is a prospective cohort study conducted with 1,121 pregnant aged 18 to 49 years, who attended the prenatal program devised by the Brazilian Family Health Strategy, Recife, PE, Northeastern Brazil, between July 2005 and December 2006. We interviewed 1,121 women during pregnancy and 1,057 after childbirth. Unintended pregnancy was evaluated during the first interview and postpartum depression symptoms were assessed using the Edinburgh Postnatal Depression Screening Scale. The crude and adjusted odds ratios for the studied association were estimated using logistic regression analysis. RESULTS The frequency for unintended pregnancy was 60.2%; 25.9% presented postpartum depression symptoms. Those who had unintended pregnancies had a higher likelihood of presenting this symptoms, even after adjusting for confounding variables (OR = 1.48; 95%CI 1.09;2.01. When the Self Reporting Questionnaire (SRQ-20 variable was included, the association decreased, however, remained statistically significant (OR = 1.42; 95%CI 1.03;1.97. CONCLUSIONS Unintended pregnancy showed association with subsequent postpartum depressive symptoms. This suggests that high values in Edinburgh Postnatal Depression Screening Scale may result from unintended pregnancy.

    Full Text Available BACKGROUND: Depression is prevalent among women and associated with reduced quality of life, and therefore it is important to determine its incidence in adult women, especially in those with breast cancer. OBJECTIVE: To determine the occurrence of depression in women who underwent conservative surgery for breast cancer with or without breast reconstruction. METHODS: Seventy-five women aged between 18 and 65 years were enrolled. Patients had undergone conservative surgery for breast cancer with immediate breast reconstruction (n = 25 or without breast reconstruction (n = 25 at least one year before the study. The control group consisted of 25 women without cancer, but of similar age and educational level distribution as the other two groups. The Beck Depression Inventory was used to measure depression. The collected data were assessed using analysis of variance and the χ2 test. RESULTS: There were no significant differences between groups in age (p = 0.72 or educational level (p = 0.20. A smaller number of patients had undergone the menopause (p = 0.02 in the control group than in other groups. There were no significant differences in occurrence of depression between groups (χ2=9.97; p = 0.126. CONCLUSÍON: Conservative surgery for breast cancer did not affect the occurrence of depression in women, regardless of whether breast reconstruction was performed.

    Earlier research has investigated the association between parental separation and long-term health outcomes among offspring, but few studies have assessed the potentially moderating role of mental health status in adolescence. The aim of this study was to analyze whether parental separation in childhood predicts depression in adulthood and whether the pattern differs between individuals with and without earlier depression. A community-based sample of individuals with adolescent depression in 1991-93 and matched non-depressed peers were followed up using a structured diagnostic interview after 15 years. The participation rate was 65% (depressed n = 227; non-depressed controls n = 155). Information on parental separation and conditions in childhood and adolescence was collected at baseline. The outcome was depression between the ages 19-31 years; information on depression was collected at the follow-up diagnostic interview. The statistical method used was binary logistic regression. Our analyses showed that depressed adolescents with separated parents had an excess risk of recurrence of depression in adulthood, compared with depressed adolescents with non-separated parents. In addition, among adolescents with depression, parental separation was associated with an increased risk of a switch to bipolar disorder in adulthood. Among the matched non-depressed peers, no associations between parental separation and adult depression or bipolar disorder were found. Parental separation may have long-lasting health consequences for vulnerable individuals who suffer from mental illness already in adolescence.

    Full Text Available Background: Schizophrenia is one of the severe forms of mental illness which demands enormous personal and economical costs. Recent years have attracted considerable interest in the dual problem of depression in schizophrenia and its relation to insight. Most clinicians believe that poor insight in patients with schizophrenia, though problematic for treatment adherence, may be protective with respect to suicide. The assumption is that patients who do not believe that they are ill are less likely to be suicidal. Alternatively, those patients with schizophrenia who recognize and acknowledge the illness will be more of a suicidal nature. Aim of the Study: The aim of the study is to find out the correlation between insight and depression in schizophrenic population. Materials and Methods: This study is a cross-sectional, single-centred, correlation study done in a total of 60 subjects. Inclusion Criteria - Subjects between 20-60 years, who were diagnosed to have schizophrenia as per International clasification of diseases-10 and who have given written consent to participate in the study. Exclusion Criteria - Subjects who have other diagnosis such as mood disorder, schizoaffective disorder, mental retardation, epilepsy or detectable organic disease and co morbid substance abuse are excluded from the study. Schizophrenics who have acute exacerbation are also excluded. Instruments - For insight assessment, schedule for assessment of insight, a three item rating scale, is used. For depressive symptoms assessment a nine item rating scale, Calgary depression rating scale, is administrated. Results: Insight and depression are strongly correlated in schizophrenic population with a Pearson correlation coefficient of 0.758. The correlation between insight and depression is high in subjects with less duration of illness. Conclusion: Better insight was significantly correlated with lower mood. In addition, it suggests that poor insight may protect against

    Abstract Background: Premature ejaculation (PE) is the most prevalent male sexual dysfunction. Epidemiologic findings are inconsistent concerning the risk for depression associated with PE. Objective: The aim of this study was to investigate the potential association between between depression and risk of PE. Data sources: We conducted a literature search of PubMed, Embase, and the Cochrane Library from these databases’ inception through June 2014 for observational epidemiological studies examining the association between depression on risk of PE. Study eligibility criteria: Studies were selected if they reported the risk estimates for PE associated with depression. Participants: patients>18 years of age suffering from PE. Interventions: a history of depressive disorder. Study appraisal and synthesis methods: These odds ratios (ORs) were pooled using a random or fixed effects model and were tested for heterogeneity. Subgroup analysis was employed to explore heterogeneity. Results: Eight trials involving 18,035 patients were included in the meta-analysis. Depression were statistically significantly associated with the risk of PE (OR = 1.63, 95% CI:1.42–1.87). There was no evidence of between-study heterogeneity (P = 0.623, I2 = 0.0%). The association was similar when stratified by mean age, geographical area, study design, sample size, publication year, and controlling key confounders. Limitations: The severity of depression and PE could not be identified due to unavailable data of trials. No evidence of publication bias was observed. Conclusions: These findings provide evidence that depression is associated with a significantly increased risk of PE. In addition, more prospective studies are necessary to evaluate the association and identify the ideal treatment. Systematic review registration number: CRD42016041272 PMID:27583879

Eighty-five outpatients with depressive disorders were interviewed using the Mini International Neuropsychiatric Inventory to assess for depression, in accordance with the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision and using the Thai version of the Structured Clinical Interview for PDs to assess for PD.Results: Seventy-seven percent of the patients had at least one PD, 40% had one PD and 60% had two or more PDs (mixed cluster. The most common PDs found were borderline PD (20% and obsessive–compulsive PD (10.6%, while the occurrence of avoidant PD was low when compared to the findings of previous, related studies. Among the mixed cluster, cluster A combined with cluster C was the common mix. Both dysthymic disorder and double depression were found to have a higher proportion of PDs than major depressive disorder (85.7% versus 76.1%. Dependent PD was found to be less common in this study than in previous studies, including those carried out in Asia.Conclusion: The prevalence of PDs among those with depressive disorder varied, and only borderline PD seems to be consistently high within and across cultures. Mixed cluster plays a prominent role in depression, so more attention should be paid to patients in this category.

    Full Text Available Introduction: Major depressive disorder is one of the most prevalent psychiatric disorders and is associated with a severe impact on the personal functioning, thus with incurring significant direct and indirect costs. The presence of depression in patients with medical comorbidities increases the risks of myocardial infarction and decreases diabetes control, and adherence to treatment. The mechanism through which these effects are produced is still uncertain. Objectives of this study were to evaluate the metabolic alterations in female Wistar rats with induced depression, with and without administration of Agomelatine. The methods included two experiments. All data were analyzed by comparison with group I (control, and with each other. In the first experiment we induced depression by: exposure to chronic mild stress-group II; olfactory bulbectomy-group III; and exposure to chronic mild stress and hyperlipidic/ hyper caloric dietgroup IV. The second experiment was similar with the first but the rats received Agomelatine (0.16mg/ animal: group V (depression induced through exposure to chronic mild stress, VI (depression induced through olfactory bulbectomy and VII (depression induced through exposure to chronic mild stressing hyperlipidic/ hypercaloric diet. Weight, cholesterol, triglycerides and glycaemia were measured at day 0 and 28, and leptin value was measured at day 28. The results in the 1st experiment revealed significant differences (p<0.01 for weight and cholesterol in Group IV, for triglycerides in groups III and IV (p<0.001, and for glycaemia in group II. The 2nd experiment revealed significant differences (p<0.001 in group VII for weight and triglycerides, and in groups V and VI for triglycerides (p<0.01. In conclusion, significant correlations were found between high level of triglycerides and depression induced by chronic stress and olfactory bulbectomy. Agomelatine groups had a lower increase of triglycerides levels.

  9. [Depression in the workplace].

    Depression is the object of a dense literature, and synthesizing it is more of a utopian ideal rather than a concrete possibility. Several specific risk factors for mental health are found in the workplace: work overloads, defective communications, role conflicts, competitive climate, and tolerance of violence. At the same time, few preventive measures have been implemented against mental disorders at work, nor are many protective factors present. One worker in ten suffers from depression, anxiety, stress, or overwork. To be distinguished from "burnout", depressive symptoms must induce clinically significant suffering with substantial deterioration in functioning at work. For depression to be recognized as a workplace accident, the employee must show that it was triggered by an unforeseen and sudden event (or at least one certainly) due to or at work. The causal link between an event at work and the depression must be shown (in particular by expert medical testimony about stress factors and indicators of vulnerability to depression). Its recognition as an occupational disease can be based on the presence of psychosocial factors described by models of workplace stress and on its description by the occupational physician.

    Full Text Available Aim of the study. Study aims were to compare neuropsychological functioning of depressed bipolar patients and healthy controls and to estimate relationship between severity of depressive symptoms and cognitive functioning. Method. Cognitive functions were examined in 30 depressed bipolar patients aged 18-68 (M=45,6, SD=12,6; 18 women and 12 men who fulfilled ICD-10 criteria for depressive episode (Hamilton Depression Rating Scale score ≥11. The comparison group consisted of 30 healthy subjects aged 23-71 (M=46, 20 women and 10 men matched in age, years of education and gender to bipolar group. A neuropsychological battery assessed executive functions and working memory. Results. The bipolar patients in depression revealed neuropsychological deficits in working memory and some aspects of executive functions in comparison to healthy group. Only in WCST test both groups received similar results. Neuropsychological functioning seems to be independent of the severity of depressive symptoms. Discussion. Different aspects of working memory and executive functions are impaired in depression period of bipolar disorder and they seem independent of the severity of depressive symptoms. These results are consistent with previous reports. Conclusions. In patients with bipolar depression cognitive assessment should be taken into account in the diagnosis and the disturbances in executive functions and working memory should be treated with neuropsychological rehabilitation and / or pharmacotherapy.

    Full Text Available Abstract Background Little is known about seasonality of specific depressive symptoms and anxiety symptoms in different patient populations. This study aims to assess seasonal variation of depressive and anxiety symptoms in a primary care population and across participants who were classified in diagnostic groups 1 healthy controls 2 patients with a major depressive disorder, 3 patients with any anxiety disorder and 4 patients with a major depression and any anxiety disorder. Methods Data were used from the Netherlands Study of Depression and Anxiety (NESDA. First, in 5549 patients from the NESDA primary care recruitment population the Kessler-10 screening questionnaire was used and data were analyzed across season in a multilevel linear model. Second, in 1090 subjects classified into four groups according to psychiatric status according to the Composite International Diagnostic Interview, overall depressive symptoms and atypical versus melancholic features were assessed with the Inventory of Depressive Symptoms. Anxiety and fear were assessed with the Beck Anxiety Inventory and the Fear questionnaire. Symptom levels across season were analyzed in a linear regression model. Results In the primary care population the severity of depressive and anxiety symptoms did not show a seasonal pattern. In the diagnostic groups healthy controls and patients with any anxiety disorder, but not patients with a major depressive disorder, showed a small rise in depressive symptoms in winter. Atypical and melancholic symptoms were both elevated in winter. No seasonal pattern for anxiety symptoms was found. There was a small gender related seasonal effect for fear symptoms. Conclusions Seasonal differences in severity or type of depressive and anxiety symptoms, as measured with a general screening instrument and symptom questionnaires, were absent or small in effect size in a primary care population and in patient populations with a major depressive disorder and

    2012-08-01

    This review evaluates research addressing the association between parent-child emotional interactions and the development and maintenance of depression in adolescence, with a focus on studies using observational research methods that assess parental responses to children and adolescents' emotional displays. We argue that parental socialization behaviors in response to different emotions expressed by youths may have distinct associations with depressive outcomes. In particular, parental behaviors that reinforce depressive behavior, reciprocate aggression, and fail to positively reinforce positive behavior have each been associated with youth depression. This review identifies a need for more observational research, including prospective, longitudinal studies, to better understand these behaviors, elucidate the directionality of influence between parental socialization behaviors and youth depression, and more clearly identify protective parental socialization behaviors. However, the use of existing findings to inform family-based interventions may improve prevention and treatment efforts directed at youth depression.

    Full Text Available Many of breast-cancer patients experience distress and most of them experience depression which may lead to amplification of physical symptoms, increased functional impairment, and poor treatment adherence. We did a review on available literature from PubMed about prevalence, distress magnitudes, coping styles, and treatment methods of major depression in women with breast cancer from 1978 to 2010. Diagnosis and treatment of depressive episodes in women with breast cancer is challenging because of overlapping symptoms and co-morbid conditions. Major depression is often under-recognized and undertreated among breast cancer patients. This review highlighted the issues on identifying and managing depression in breast cancer patients in clinical settings.

    2008-09-01

    Under-diagnosis and under-treatment of depression are major problems in nursing home residents. The purpose of this study was to determine antidepressant use among nursing home residents who were diagnosed with depression using three different methods: (1) the Geriatric Depression Scale, (2) Minimum Data Set, and (3) primary care provider assessments. As one would expect, the odds of being treated with an antidepressant were about eight times higher for those diagnosed as depressed by the primary care provider compared to the Geriatric Depression Scale or the Minimum Data Set. Men were less likely to be diagnosed and treated with antidepressants by their primary care provider than women. Depression detected by nurses through the Minimum Data Set was treated at a lower rate with antidepressants, which generates issues related to interprofessional communication, nursing staff communication, and the need for geropsychiatric role models in nursing homes.

    Objectives Studies suggest early onset depression (EOD) is associated with a more severe course of the depressive disorder, while late onset depression (LOD) is associated with more cognitive and neuroimaging changes. This study examined if older adults with EOD, compared with those with LOD, would exhibit more severe symptoms of depression and, consistent with the glucocorticoid cascade hypothesis, have more hippocampal volume loss. A second goal was to determine if LOD, compared with EOD, would demonstrate more cognitive and neuroimaging changes. Method At regular intervals over a four year period non-demented, older, depressed adults were assessed on the Mini Mental Status Examination (MMSE) and the Montgomery-Asberg Depression Rating Scale (MADRS). They were also assessed on Magnetic Resonance Imaging (MRI). Results Compared with LOD, EOD had more depressive symptoms, more suicidal thoughts, and less social support. Growth curve analyses indicated that EOD demonstrated higher levels of residual depressive symptoms over time. The LOD group exhibited a greater decrement in cognitive scores. Contrary to the glucocorticoid cascade hypothesis, participants with EOD lost right hippocampal volume at a slower rate than did participants with LOD. Right cerebrum gray matter was initially smaller among participants with LOD. Conclusions EOD is associated with greater severity of depressive illness. LOD is associated with more severe cognitive and neurological changes. These differences are relevant to understanding cognitive impairment in geriatric depression. PMID:22934752

    Full Text Available OBJECTIVES: To examine the association of life events and social support in the broadly defined category of depression in late life. INTRODUCTION: Negative life events and lack of social support are associated with depression in the elderly. Currently, there are limited studies examining the association between life events, social support and late-life depression in Brazil. METHODS: We estimated the frequency of late-life depression within a household community sample of 367 subjects aged 60 years or greater with associated factors. ''Old age symptomatic depression'' was defined using the Composite International Diagnostic Interview 1.1 tool. This diagnostic category included only late-life symptoms and consisted of the diagnoses of depression and dysthymia as well as a subsyndromal definition of depression, termed ''late subthreshold depression''. Social support and life events were assessed using the Comprehensive Assessment and Referral Evaluation (SHORT-CARE inventory. RESULTS: ''Old age symptomatic depression'' occurred in 18.8% of the patients in the tested sample. In univariate analyses, this condition was associated with female gender, lifetime anxiety disorder and living alone. In multivariate models, ''old age symptomatic depression'' was associated with a perceived lack of social support in men and life events in women. DISCUSSION: Social support and life events were determined to be associated with late-life depression, but it is important to keep in mind the differences between genders. Also, further exploration of the role of lifetime anxiety disorder in late-life depression may be of future importance. CONCLUSIONS: We believe that this study helps to provide insight into the role of psychosocial factors in late-life depression.

    Seth A Berkowitz

    Full Text Available PURPOSE: Depression is common in primary care but often under-treated. Personal experiences with depression can affect adherence to therapy, but the effect of vicarious experience is unstudied. We sought to evaluate the association between a patient's vicarious experiences with depression (those of friends or family and treatment preferences for depressive symptoms. METHODS: We sampled 1054 English and/or Spanish speaking adult subjects from July through December 2008, randomly selected from the 2008 California Behavioral Risk Factor Survey System, regarding depressive symptoms and treatment preferences. We then constructed a unidimensional scale using item analysis that reflects attitudes about antidepressant pharmacotherapy. This became the dependent variable in linear regression analyses to examine the association between vicarious experiences and treatment preferences for depressive symptoms. RESULTS: Our sample was 68% female, 91% white, and 13% Hispanic. Age ranged from 18-94 years. Mean PHQ-9 score was 4.3; 14.5% of respondents had a PHQ-9 score >9.0, consistent with active depressive symptoms. Analyses controlling for current depression symptoms and socio-demographic factors found that in patients both with (coefficient 1.08, p = 0.03 and without (coefficient 0.77, p = 0.03 a personal history of depression, having a vicarious experience (family and friend, respectively with depression is associated with a more favorable attitude towards antidepressant medications. CONCLUSIONS: Patients with vicarious experiences of depression express more acceptance of pharmacotherapy. Conversely, patients lacking vicarious experiences of depression have more negative attitudes towards antidepressants. When discussing treatment with patients, clinicians should inquire about vicarious experiences of depression. This information may identify patients at greater risk for non-adherence and lead to more tailored patient-specific education about

  5. The role of Melancholia in prostate cancer patients' depression

    2011-12-01

    Full Text Available Abstract Background Although it is well established that prostate cancer (PCa patients are more likely to experience clinical depression than their age-matched non-prostate cancer peers, and that such depression can have negative effects upon survival, little is known about the underlying nature of the depressive symptomatology that these men experience. In particular, the incidence of melancholic symptoms of depression, which are signs of increased risk of suicide and resistance to treatment, has not previously been reported in PCa patients. The present study aimed to measure the incidence and nature of Melancholia in PCa depression. Method A sample of 507 PCa patients in Queensland, Australia, completed anonymous and confidential questionnaires about their background, treatment status, and depression. Data were analysed to select depressive symptoms that were part of the definition of Melancholia vs those which were not. Regression was used to determine the links between Melancholia and overall depressive status, and factor analysis revealed the underlying components of Melancholia, which were mapped over time since diagnosis for 3 years. Results Psychometric data were satisfactory. Melancholia significantly predicted depressive status for the most depressed subset of patients, but not for the total sample. Melancholia was factored into its components of Anhedonia and Agitation, and the first of these was more powerful in predicting Melancholia. Variability over the 3 years following diagnosis was noted for each of these two components of Melancholia. Conclusions The strong presence of Melancholia in the depressive symptomatology of this sample of PCa patients suggests that some forms of treatment for depression may be more likely to succeed than others. The dominance of Anhedonia and Agitation over other symptoms of Melancholia also holds implications for treatment options when assisting these men to cope with their depression.

    Objectives To describe the duration of bipolar I major and minor depressive episodes and factors associated with time to recovery. Method 219 participants with bipolar I disorder based on Research Diagnostic Criteria analogs to DSM-IV-TR criteria were recruited from 1978–1981 and followed for up to 25 years. Psychopathology was assessed with the Longitudinal Interval Follow-up Evaluation. The probability of recovery over time from multiple successive depressive episodes was examined with survival analytic techniques, including mixed-effects grouped-time survival models. Results The median duration of major depressive episodes was 14 weeks, and over 70% recovered within 12 months of onset of the episode. The median duration of minor depressive episodes was 8 weeks, and approximately 90% recovered within 6 months of onset of the episode. Aggregated data demonstrated similar durations of the first three major depressive episodes. However, for each participant with multiple episodes of major depression or minor depression, the duration of each episode was not consistent (intraclass correlation coefficient=0.07 and 0.25 for major and minor depression, respectively). The total number of years in episode over follow-up with major plus minor depression prior to onset of a major depressive episode was significantly associated with a decreased probability of recovery from that episode; with each additional year, the likelihood of recovery was reduced by 7% (hazard ratio: 0.93, 95% CI: 0.89–0.98, p=0.002). Conclusions Bipolar I major depression generally lasts longer than minor depression, and the duration of multiple episodes within an individual varies. However, the probability of recovery over time from an episode of major depression appears to decline with each successive episode. PMID:23561241

    IMPORTANCE Medical students are at high risk for depression and suicidal ideation. However, the prevalence estimates of these disorders vary between studies. OBJECTIVE To estimate the prevalence of depression, depressive symptoms, and suicidal ideation in medical students. DATA SOURCES AND STUDY SELECTION Systematic search of EMBASE, ERIC, MEDLINE, psycARTICLES, and psycINFO without language restriction for studies on the prevalence of depression, depressive symptoms, or suicidal ideation in medical students published before September 17, 2016. Studies that were published in the peer-reviewed literature and used validated assessment methods were included. DATA EXTRACTION AND SYNTHESIS Information on study characteristics; prevalence of depression or depressive symptoms and suicidal ideation; and whether students who screened positive for depression sought treatment was extracted independently by 3 investigators. Estimates were pooled using random-effects meta-analysis. Differences by study-level characteristics were estimated using stratified meta-analysis and meta-regression. MAIN OUTCOMES AND MEASURES Point or period prevalence of depression, depressive symptoms, or suicidal ideation as assessed by validated questionnaire or structured interview. RESULTS Depression or depressive symptom prevalence data were extracted from 167 cross-sectional studies (n = 116 628) and 16 longitudinal studies (n = 5728) from 43 countries. All but 1 study used self-report instruments. The overall pooled crude prevalence of depression or depressive symptoms was 27.2% (37 933/122 356 individuals; 95% CI, 24.7% to 29.9%, I2 = 98.9%). Summary prevalence estimates ranged across assessment modalities from 9.3% to 55.9%. Depressive symptom prevalence remained relatively constant over the period studied (baseline survey year range of 1982–2015; slope, 0.2% increase per year [95% CI, −0.2% to 0.7%]). In the 9 longitudinal studies that assessed depressive symptoms before and during

    The prevalence of depression appears to have increased over the past three decades. While this may be an artefact of diagnostic practices, it is likely that there are factors about modernity that are contributing to this rise. There is now compelling evidence that a range of lifestyle factors are involved in the pathogenesis of depression. Many of these factors can potentially be modified, yet they receive little consideration in the contemporary treatment of depression, where medication and psychological intervention remain the first line treatments. "Lifestyle Medicine" provides a nexus between public health promotion and clinical treatments, involving the application of environmental, behavioural, and psychological principles to enhance physical and mental wellbeing. This may also provide opportunities for general health promotion and potential prevention of depression. In this paper we provide a narrative discussion of the major components of Lifestyle Medicine, consisting of the evidence-based adoption of physical activity or exercise, dietary modification, adequate relaxation/sleep and social interaction, use of mindfulness-based meditation techniques, and the reduction of recreational substances such as nicotine, drugs, and alcohol. We also discuss other potential lifestyle factors that have a more nascent evidence base, such as environmental issues (e.g. urbanisation, and exposure to air, water, noise, and chemical pollution), and the increasing human interface with technology. Clinical considerations are also outlined. While data supports that some of these individual elements are modifiers of overall mental health, and in many cases depression, rigorous research needs to address the long-term application of Lifestyle Medicine for depression prevention and management. Critically, studies exploring lifestyle modification involving multiple lifestyle elements are needed. While the judicious use of medication and psychological techniques are still advocated

    Full Text Available The diagnosis of depression. Depressive disorder is nowadays diagnosed by the two widely used diagnostic systems - International Classification of Diseases of the World Health Organization, 10th revision and the Diagnostic and Statistical Manual Criteria of the American Psychiatric Organisation, 4th edition. The criteria for depressive disorder used in these two systems are almost identical. Poststroke depression. The diagnosis of depression may be difficult to establish in stroke patients, especially in patients with aphasia/dysphasia, anosognosia and other cognitive dysfunction. Major vs. minor poststroke depression, specificity and sensitivity of depressive symptoms: The phenomenology of major poststroke depression has been found to be similar to that of primary depression, and it appears that minor and major are not stages of the same continuum, but rather separate entities. Contrary to common opinion, non specific somatic symptoms do not hinder the diagnosis of poststroke depression and can be highly discriminative and crucial in the evaluation of poststroke depression. Validity of the poststroke depression diagnosis Studies have shown that a valid diagnosis of poststroke depression may be established successfully using structured or semi-structured neuropsychiatric interviews, according to the current Diagnostic and Statistical Manual Criteria. Conclusion. It appears that no new diagnostic tools specific for major depression in stroke patients are necessary. The existing diagnostic procedures will fail to diagnose or misdiagnose depression only in few stroke patients.

    Full Text Available Orientation: Work engagement, burnout and stress-related ill health levels of individuals,suffering from depression, who are unsure whether or not they suffer from depression, or whodo not suffer from depression, have not been investigated in South Africa.Research purpose: The main objectives of this study were to investigate the prevalence ofdepression amongst employees in South African organisations and the relationship ofdepression with specific well-being constructs.Motivation for the study: Organisations should know about the prevalence of depression andthe effects this could have on specific well-being constructs.Research design, approach and method: A cross-sectional design was followed. Theavailability sample (n = 15 664 included participants from diverse demographics. The SouthAfrican Employee Health and Wellness Survey was followed to measure constructs.Main findings: The results showed that 18.3% of the population currently receive treatment fordepression, 16.7% are unsure whether or not they suffer from depression and 65% do not sufferfrom depression. Depression significantly affects the levels of work engagement, burnout andthe occurrence of stress-related ill health symptoms.Practical/managerial implications: This study makes organisations aware of the relationshipbetween depression and employee work-related well-being. Proactive measures to promote thework-related well-being of employees, and to support employees suffering from depression,should be considered.Contribution/value-add: This study provides insight into the prevalence of depression andwell-being differences that exist between individuals, suffering from depression, who areunsure whether or not they suffer from depression, and who do not suffer from depression.

    Full Text Available Background. Obese individuals who suffer from major depressive disorder are routinely screened out of weight loss trials. Treatments targeting obesity and depression concurrently have not been tested. Purpose. To test the short-term efficacy of a treatment that combined behavioral weight management and cognitive behavioral therapy (CBT for obese adults with depression. Methods. Twelve obese females diagnosed with major depressive disorder received weekly group behavioral weight management, combined with CBT for depression, for 16 weeks. Weight, symptoms of depression, and cardiovascular disease (CVD risk factors were measured at baseline and week 16. Results. Participants lost 11.4% of initial weight and achieved significant improvements in symptoms of depression and CVD risk factors. Conclusions. Obese individuals suffering from major depressive disorder can lose weight and achieve improvements in symptoms of depression and CVD risk factors with 16 weeks of combined treatment. A larger randomized controlled trial is needed to establish the efficacy of this treatment.

    Full Text Available Abstract Objective To validate the ICD-10 diagnosis of a single depressive episode as used in daily clinical psychiatric practice and as recorded in the Danish Psychiatric Central Research Register. Methods Patients discharged with a diagnosis of a single depressive episode were consecutively sampled from the register and diagnosed according to an interview using the Schedules for Clinical Assessment in Neuropsychiatry (SCAN. Results A total of 75.4% of 399 patients with a register diagnosis of a single depressive episode also got this diagnosis according to the SCAN interview (82.8% for severe type of a single depression, 76.0% for moderate type of a single depression and 65.2% for mild type of a single depression. Conclusion The ICD-10 diagnosis of a single depressive episode can be used in daily clinical practice with sufficient precision. The validity of the diagnosis is highest for severe and moderate type of depression and decreases for mild depression.

    2015-01-01

    Introduction Persistent depressive disorder (PDD) introduced in the Diagnostic and Statistical Manual of Mental Disorders (DSM) 5 as a novel diagnostic category represents a consolidation of two separate DSM-IV categories, chronic major depressive disorder (MDD) and dysthymic disorder. The present study aims to investigate the frequency and clinical as well as socio-demographic correlates of PDD in comparison with those of episodic MDD among patients seeking treatment for depressive symptoms. Methods Participants were 140 depressive out-and in-patients under treatment at the psychiatry clinic of the Adnan Menderes University Research Hospital. Each patient was assessed by means of a structured clinical interview (SCID-I) and relevant psychometric instruments including the Hamilton Depression Inventory and Eskin Suicidal Behavior Inventory. Results Among the depressive patients, 61% fulfilled the criteria for PDD and 39% for episodic MDD. As compared with patients with episodic MDD, the PDD patients were older (d=.54), lower in educational attainment (d=.55), more likely to have comorbid generalized anxiety disorder (OR=3.7), and more prone to report symptoms of anxiety, hopelessness, pessimism, and somatic complaints. Nevertheless, the PDD patients displayed heterogeneous characteristics with respect to clinical severity and suicidal behavior. Conclusion Our findings suggest that majority of depressive patients, including those fulfilling the criteria for MDD, have been suffering from a persistent ailment rather than an episodic disorder. Clinicians with a cross-sectional perspective are more likely to diagnose MDD, whereas those with a longitudinal perspective are more likely to identify PDD in the majority of depressive patients. The incorporation of both of these perspectives into DSM-5 in a complementary manner will possibly enhance our insight into depressive disorders and improve our treatment results. PMID:28360740

    Many empirical studies have indicated that various psychosocial and psychiatric variables are correlated with levels of self-stigma. Treatment methods for reducing self-stigma have been investigated in recent years, especially those examining the relationship between negative cognitive schemata and self-stigma. This study examined the relationship of self-stigma with cognitive schemata, depression, and self-esteem in depressive patients. Furthermore, structural equation modeling (SEM) was conducted to evaluate three hypothetical models. Study participants were 110 patients with depression (54 men, 56 women; mean age=45.65years, SD=12.68; 83 diagnosed with mood disorders; 22 with neurotic, stress-related, or somatoform disorders; and 5 with other disorders) attending a psychiatric service. Outcomes were measured using the Japanese versions of the Devaluation-Discrimination Scale, Dysfunctional Attitude Scale, Center for Epidemiologic Studies Depression Scale, and Rosenberg's Self Esteem Scale. The analysis indicated a better fit of the model that assumed self-stigma as mediator, suggesting that cognitive schemata influence self-stigma, while self-stigma affects depression and self-esteem. The tested models using SEM indicated that (1) self-stigma has the potential to mediate the relationship between cognitive schemata and depression, and (2) depression and self-stigma have a similar influence on self-esteem. Although low self-esteem is considered one of the symptoms of depression, when we aim to recover self-esteem, we do not only observe improvement in depressive symptoms; thus, approaches that focus on the reduction of self-stigma are probably valid.

    This study focuses on the relationships of workaholism to job burnout and depression of university teachers. The direct and indirect (via job burnout) effects of workaholism on depression were investigated in 412 Chinese university teachers. Structural equation modeling and bootstrap method were used. Results revealed that workaholism, job burnout, and depression significantly correlated with each other. Structural equation modeling and bootstrap test indicated the partial mediation role of job burnout on the relationship between workaholism and depression. The findings shed some light on how workaholism influenced depression and provided valuable evidence for prevention of depression in work.

    Late-life depression is common among nursing home residents, but often is not addressed by nurses. Using a self-directed CD-based depression training program, this pilot study used mixed methods to assess feasibility issues, determine nurse perceptions of training, and evaluate depression-related outcomes among residents in usual care and training conditions. Of 58 nurses enrolled, 24 completed the training and gave it high ratings. Outcomes for 50 residents include statistically significant reductions in depression severity over time (p Depression training is an important vehicle to improve depression recognition and daily nursing care, but diverse factors must be addressed to assure optimal outcomes.

    Full Text Available Postpartum blues which is seen during the postpartum period is a transient psychological state. Most of the mothers experience maternity blues in postpartum period. It remains usually unrecognized by the others. Some sensitive families can misattribute these feelings as depression. In this article, we tried to review the characteristics of maternity blues and its differences from depression. We defined depression and presented the incidence and diagnostic criteria, of major depression as well as the risk factors and clinic findings of postpartum depression. Thus, especially at primary care we aimed to prevent misdiagnosis of both maternity blues and depression

    McKendree-Smith, N; Scogin, F

    2000-12-01

    This study examined the theory of depressive realism, which posits that depressed people often are more accurate in perceptions and judgments than nondepressed people. Two possible qualifications to this theory were examined: (1) severity of depression moderates the effect, and (2) length of processing time will impact the presence of bias in depressed people, that is, negative bias will develop over time. College students were presented with a bogus personality profile that actually consisted of items previously rated as neutral in desirability. Participants rated these profiles for desirability initially and then again three days later. Results indicated a significant effect of depression severity on desirability rating. Nondepressed and mildly depressed students found their profiles to be more positive than the moderately/severely depressed students, with both groups having scores in the positive range. However, those participants who were moderately/severely depressed showed a negative bias in their ratings. No support was found for the effect of different times of interpretation.

Perfectionistic dysfunctional attitudes are beliefs and attitudes about achievement and excessive fear of failure, while dependent dysfunctional attitudes are beliefs and attitudes about dependency on, and approval from, others. Subthreshold depression refers to a depressive state that does not meet the diagnostic criteria for a major depressive episode. This study examined whether the difference in perfectionistic dysfunctional attitudes between college students with subthreshold depression and those with no depression would be greater than that of dependent dysfunctional attitudes.Methods: Participants were defined as having subthreshold depression if they scored 16 or higher on the Japanese version of the Center for Epidemiologic Studies Depression Scale but did not meet the diagnostic criteria for a major depressive episode, as assessed by the major depressive episode module of the Mini-International Neuropsychiatric Interview. The participants included 21 male and 87 female college students, with a mean age of 20.3 years. Dysfunctional attitudes were evaluated with the Japanese version of the 24-item Dysfunctional Attitude Scale.Results: Of the 108 students, 34 had subthreshold depression while 74 had no depression. The magnitudes of the differences in perfectionistic and dependent dysfunctional attitudes between the students with
