Relations Between Depression Level and Conflict Resolution Styles,Marital Adjustments of Patients With Major Depression and Their Spouses

The objective of this study was to determine to relations between the depression level and the conflict resolution styles, marital adjustments of the depressed patients and to analyze the conflict resolution styles, marital adjustments of both the patients and their spouses as the possible predictors of depression levels. The research comprised 113 patients with major depression and their spouses. While there was a negative correlation between depression scores and positive and subordination conflict resolution styles subscales of the patients, there was a positive correlation between the depression scores and negative conflict resolution style subscale. Negative correlation was observed between the depression and marital adjustment scores of patients (p < 0.05). The conflict resolution styles and marital adjustment of depressed patients and their spouses are predictors of depression in patients.     

The effectiveness of Pilates for partial anterior cruciate ligament injury

Purpose

This study explored the effects of Pilates on the muscle strength, function, and instability of patients with partial anterior cruciate ligament (ACL) injuries in situations in which a non-surgical treatment option is preferred.

Methods

Fifty participants 20–45 years of age who were diagnosed with isolated ACL injuries were included in the study. The participants were randomly assigned to either the Pilates exercise group (n = 24) or the control group (n = 26). The subjects in the Pilates exercise group performed basic mat exercises that focused on the muscle strength and flexibility of the lower limbs and core muscles during each class session, which met three times per week for 12 weeks. The control group did not receive any treatment or home exercise programme. All patients were evaluated using the Lysholm Knee Scale, the Cincinnati Knee Rating System, and isokinetic quadriceps and hamstring strength. Patient satisfaction regarding improvement in knee stability was assessed using the Global Rating of Change scale.

Results

The Pilates group experienced significant improvement over the control group as measured by the difference in quadriceps strength at 12 weeks (p = 0.03). Both groups showed some clinical change over time, but the Pilates group improved for all outcome measurements at the 12-week follow-up, and the control group only improved for functional outcomes. Patient satisfaction with the level of knee stability based on the Global Rating of Change scale was higher in the Pilates group than in the control group.

Conclusion

Although both groups exhibited improvements in knee strength and functional outcomes, the results suggest that Pilates is a superior management approach over a control treatment for increasing quadriceps strength in participants with partial ACL injury. Pilates may provide clinicians a novel option when choosing a treatment for a partial ACL injury. Further study is needed to determine whether certain subgroups of individuals might achieve an added benefit with this approach.

High-performance liquid chromatographic method for the determination of di(2-ethylhexyl) phthalate in total parenteral nutrition and in plasma

A simple, rapid and sensitive reversed-phase high-performance liquid chromatographic method with UV detection was developed for the quantification of di(2-ethylhexyl) phthalate (DEHP) in parenteral nutrition admixtures containing fat emulsion and in plasma samples of children daily treated by total parenteral nutrition. The analyte and the internal standard, di-n-heptyl phthalate, were extracted twice using hexane and the organic layer separated and dried under nitrogen. The residues were reconstituted with acetonitrile and 20 microl was injected into a Waters Spherisorb C18 column, the UV detector was set at 202 nm. The mobile phase was acetonitrile-aqueous buffer (triethylamine 0.08% adjusted to pH 2.8 with 1 M phosphoric acid) mixture (88:12, v/v) and it was pumped at 1 ml/min. Average recoveries were 97% or greater. This method was successfully used to investigate the amounts of DEHP which can leach from bags and tubing into fat emulsion and which could contaminate children under long-term parenteral nutrition. On the other hand, the circulating DEHP concentrations were estimated in four children under regular long-term parenteral nutrition.     

Is late adolescence a real risk factor for an adverse outcome of pregnancy?

Objective: To compare the obstetrical and neonatal outcomes of late adolescent (LA) and adult pregnancies.

Methods: Between January 2012 and December 2012, a total of 313 late adolescent pregnant aged between 16 and 19 years and 418 adult pregnant women aged between 20 and 35 years having given birth in our maternity service were enrolled into this case–control study. The demographic and clinical data were reviewed from hospital database and patients’ medical records.

Results: The incidence of preterm birth (PB) in the LA group was significantly higher than in the adult group (p?=?0.001), while the incidence of gestational diabetes mellitus was significantly lower (p?=?0.001). The mean birth weight and the rate of delivered macrosomic fetuses in the study group were lower than in the control group (p?=?0.03). The LA group had significantly higher rate of vaginal delivery when compared to the adult group (p?=?0.001). Both the rate of pregnancy induced hypertensive disorders and postpartum hemorrhage were not statistically different between the two groups (p?=?0.31; p?=?0.38, respectively). The LA group had lower rate of stillbirth when compared to the adult group; however, the difference was statistically insignificant (0.3% versus 1.2%) (p?=?0.24).

Conclusions: The LA pregnancy should be closely followed up during their antenatal care period due to the significantly higher rate of PB.     

Vancomycin-resistant enterococci colonization in a neonatal intensive care unit: who will be infected?

Objective: To determine the incidence of vancomycin-resistant enterococcus (VRE) colonization in our neonatal intensive care unit (NICU) over five-year period, rate of progression to VRE infection and associated risk factors.

Methods: A retrospective analysis of a prospective surveillance for VRE colonization and health care-associated infections was made. Contact precautions were taken against colonization, although the application varied over the years due to repairs in the unit.

Results: VRE rectal colonization was detected in 200/1671 neonates (12%) admitted to NICU. It showed great interannual variability from 1.9% to 30.3%. Sytemic VRE infection developed in 6/200 VRE-colonized patients (3%) within a median of 9 days (range: 3–58 days). The risk factors for VRE infection development identified in the univariate analysis were long hospital stay (≥30 days), necrotizing enterocolitis, surgical procedure, extraventricular drainage, receipt of amphotericin B and receipt of glycopeptides after detection of VRE colonization. Crude in-hospital mortality was higher in neonates who developed a systemic VRE infection (p?<?0.001).

Conclusion: Maintaining physical conditions in the unit favorable for infection control and rational use of antibiotics are essential in the control of VRE colonization and resultant infections. Special attention should be directed to VRE-colonized babies carrying the risk factors.     

The innate immune system and HIV pathogenesis

Innate immunity represents the first line of defense against microbial infections. The innate immune system is activated by conserved structures present on most pathogens and profoundly regulates subsequent adaptive immune responses. HIV is notorious for evading and disrupting the immune system. Although HIV directly targets and gradually destroys the adaptive immunity, it has become clear that the virus also perturbs the components of the innate immune system. In this paper, we review the role of two innate lymphocyte subsets, natural killer and natural killer T cells, that are disrupted during HIV infection.     

A mixture of experts network structure for modelling Doppler ultrasound blood flow signals

Mixture of experts (ME) is a modular neural network architecture for supervised learning. This paper illustrates the use of ME network structure to guide modelling Doppler ultrasound blood flow signals. Expectation-Maximization (EM) algorithm was used for training the ME so that the learning process is decoupled in a manner that fits well with the modular structure. The ophthalmic and internal carotid arterial Doppler signals were decomposed into time-frequency representations using discrete wavelet transform and statistical features were calculated to depict their distribution. The ME network structures were implemented for diagnosis of ophthalmic and internal carotid arterial disorders using the statistical features as inputs. To improve diagnostic accuracy, the outputs of expert networks were combined by a gating network simultaneously trained in order to stochastically select the expert that is performing the best at solving the problem. The ME network structure achieved accuracy rates which were higher than that of the stand-alone neural network models.     

Relationship between Pollen Counts and Weather Variables in East-Mediterranean Coast of Turkey

BACKGROUND: Aeroallergen sampling provides information regarding the onset, duration and severity of the pollen season that clinicians use to guide allergen selection for skin testing and treatment. OBJECTIVES: This atmospheric survey reports (1) airborne pollen contributions in Adana in one-year period (2) pollen onset, duration and peak level (3) the relationship between airborne pollen and selected meteorological variables and; (4) effects on symptoms in pollen allergic children. METHODS: Pollen sampling was performed with a volumetric Burkard Spore Trap. Meteorological data were measured daily from April 2001 to April 2002. Asthma symptom scores were investigated in 186 pollen allergic children that were on follow up in pediatric allergy outpatient clinics during same period. RESULTS: Average measurements included 82.5% tree pollen, 7.7% grass pollen and 9.8% herb pollen 54 taxa were identified during one year. The most prominent tree pollens were Cupressaceae, Eucalyptus and Pinus. The most common herb was Chenopodiaceae pollen family. When airborne pollen levels were examined in relation to single meteorological conditions; daily variations in total pollen counts were not significantly correlated with any variable studied (humidity, rainfall, temperature and wind) (p > 0.05). On the other hand, statistically significant relationship between pollen concentration and symptom scores were found (p > 0.05). Positive correlations were seen between both Gramineae and Herb pollen, and humidity and rainfall from March to July. However, positive correlations were detected between tree pollen counts and temperature and humidity in May and June. CONCLUSION: This survey is the first volumetric airborne pollen analysis conducted in the survey area in Adana. This study suggested that the effects of weather on pollen count and symptom scores in this population could not be clearly identified with the evaluation of one-year data. However, pollen counts had effect on allergic symptoms in pollen allergic children. Examination of the complex interaction of multiple whether parameters would perhaps more fully elucidate the relationship between meteorology and aerobiology and provide the clinician with information necessary to forecast pollen prevalence. An awareness of the ever chancing, local aeroallergen patterns requires regular monitoring. Such awareness serves as a useful guide in the effective testing and treatment of atopic patients.
