Nursing regimens: Effects on body condition, return to postpartum ovarian cyclicity in Santa Ines ewes, and performance of lambs

The effects of nursing regimens on the body condition, onset of ovarian cyclicity postpartum and weaning weight of lambs were assessed in Santa Ines ewes. Thirty-two ewes were blocked according to parity, number of lambs, and body weight at lambing and within each block randomly allocated to treatments: continuous nursing (CN), controlled nursing (CN2) with two daily feedings for an hour after the 10th day postpartum, or early weaning (EW) with total separation from the lambs after the 10th day. The animals were evaluated from the 12th day postpartum until the first estrus or until 60th day. The dry matter and nutrients intake did not differ among treatments ( P>. 0.05) but did differ over time ( P<. 0.01). The weight, body condition score, serum concentrations of non-esterified fatty acids and prolactin, the percentages of ewes in estrus, of ewes that ovulated within 60th day and had ovulation silent, the period from lambing to estrus, ovulation and follicle with a diameter ≥5. mm and the maximum follicular diameter did not differ ( P>. 0.05) among the treatments. The percentage of ovulation until 30th day was greater ( P<. 0.05) in the EW group. The percentage of short luteal phases was higher in the CN2 and EW groups ( P=0.07) and normal luteal phases were higher in the CN group ( P=0.01). Lamb weight weaning was lower in the EW group ( P<. 0.05). It is possible to use CN to obtain lambing periods less than eight months in Santa Ines ewes, with the advantages of simpler management and higher lamb weaning weights. © 2013 Elsevier B.V.

Maternal flow-mediated dilation and nitrite concentration during third trimester of pregnancy and postpartum period

Objectives. To compare maternal flow-mediated dilation (FMD) of the brachial artery and nitrite concentration between third trimester of pregnancy (3rdT) and postpartum (PP) period. Additionally, we will evaluate whether FMD correlates with nitrite concentration in both periods. Methods. Eligibility criteria was healthy women with singleton pregnancy, gestational age >28 weeks, nonsmokers, and no personal or family history of vascular disease. Each women was examined during 3rdT and between 8 and 12 weeks PP to evaluate FMD and nitrite concentration in whole blood. Women not examined in both periods were excluded. Values between both periods were compared using paired t tests. Correlation between FMD and nitrite was examined by Pearson correlation coefficient. Significance level set as p<0.05. Results. We invited 42 pregnant women. Among them, 35 were eligible and 7 of them were excluded for not attending the PP evaluation resulting in 28 participants analyzed. We found no significant change in FMD (10.39±5.57% vs. 8.42±4.21%; p=0.11; 3rdT vs. PP, respectively) and no significant change in nitrite concentration (257.41±122.95nmol/L vs. 237.16±90.01nmol/L; p=0.28). Baseline brachial artery diameter had a significant reduction (3.11±0.30 to 2.75±0.34mm; p<0.01). No significant correlation between FMD and nitrite during 3rdT (r=-0.13; p=0.50) or PP (r=0.14; p=0.48) was found. Conclusions. We did not observe significant changes in both FMD and nitrite concentration between third trimester and the PP period. FMD did not correlate with nitrite in both periods. More studies are needed to confirm our findings. © Informa Healthcare USA, Inc.

Health-related quality of life and depression in patients with dentofacial deformity

Introduction: Patients with dentofacial deformities present difficulties at work and in social adaptation. At the same time, they often appear depressed, and as a consequence, the psychosocial aspects of surgery play an important role. The aim of this study was to investigate the effects that depression causes in the quality of life of patients with dentofacial deformity. Material and methods: Filthy patients were recruited 1 year before undergoing orthognathic surgery and correlated oral and general health with the presence and absence of depression. In order to accomplish this, these patients received an adapted questionnaires of quality of life and Beck Depression Inventory to fill out. Fisher's test was applied, with a significance level of 5 %. Intercooled Stata version 9.0 was used to analyze data. Results: Among the eight domains of quality of life, there were three associated with depression status: vitality (p < 0.001), social aspects (p = 0.011), and mental health (p = 0.008). Discussion: There is growing interest in the impact of dentofacial deformity conditions on patients' quality of life. The scientific literature has discussed the social aspects of these deformities and showed that untreated patients had low self-esteem and suffered social restrictions before making the orthodontic and surgical treatments. This study concluded that the depression interferes significantly in vitality, social aspects of the individual, and mental health and, at the same time, emphasizes that the orthognathic surgery aims to not only restore esthetics and function to the patient but also improve the quality of life. © 2012 Springer-Verlag.

Belize: Macro socio-economic assessment of the damage and losses caused by tropical depression 16

Tropical Depression 16 (TD16) crept up on disparate populations in Belize over a period 8-16 October 2008. TD16 struck less than five months after the first named tropical storm of the 2008 Atlantic season, Arthur. The storm had been forecasted to dump up to 10 inches of rain over Belize and up to 15 inches in isolated areas. Arthur had devastating effects on Belize, particularly the southern regions where bridges collapsed and lives were lost. It was in the aftermath of such devastation that Belize faced TD16. The consequence of TD16 is what falls under the purview of this assessment.

Argentina’s quarter century experiment with neoliberalism: from dictatorship to depression

Em 2002, a Argentina atingiu um novo marco histórico, ao experimentar o maior default da dívida externa, não somente pela sua própria história, mas também do mundo. Para compreender como a Argentina deixou de ser um país mais desenvolvido de terceiro mundo até experimentar a crise de 2001, entrando depois numa depressão em 2002, com mais da metade da população abaixo da linha de pobreza, precisamos fazer uma avaliação das políticas econômicas durante o último quarto de século na Argentina. A virada ao neoliberalismo começou durante a ditadura no ano 1976, tendo se aprofundado no governo Menem e sempre apoiada pelo FMI. Este trabalho tentará identificar porque a crise ocorreu naquele momento, e também, compreender as mudanças subjacentes na economia política durante duas décadas na Argentina, as quais que desencadearam duas ondas de desindustrialização, uma explosão da dívida externa e uma deterioração bem marcante no padrão de vida para a maioria dos argentinos.

Hydromorphic Soil, Topographic Depression and Vegetation Development History by Using 13c and 14c In Rondônia State (sw Brazilian Amazon)

13C e 14C obtidos da matéria orgânica do solo foram usados para diferenciar fases de flutuação da vegetação em transição floresta-savana. A região apresenta baixos platôs com depressões topográficas imperfeitamente drenadas na superfície. Na topossequência estudada foram analisados solos de cinco perfis localizados sob floresta (F), transição floresta-savana (S1), borda da depressão sob savana (S2) e centro da depressão sob savana (S3). Os valores de 13C e idades evidenciam que a ~ 200cm de profundidade, com idades entre ~ 12.000 e 10.000 A.P., valores de -27‰ a -27,7‰ indicam vegetação de floresta (C3) em todos os perfis. Na profundidade de 100 cm, com idades entre ~ 6.000 e 5.000 A.P., houve enriquecimento de – 20,2‰ a -22,3‰, indicando regressão da floresta e expansão da savana. Valores entre -15,9 e -18,7‰ a 50-60 cm, estimado entre ~ 4.700 a 3.800 A.P., sugere máxima expansão da vegetação C4 em resposta às condições climáticas mais secas, exceto no perfil S3 com valores mais empobrecidos (-20,9‰), sugerindo que na depressão, o desenvolvimento da hidromorfia possibilitou a presença de espécies de gramíneas C3 e C4 da savana em resposta as mudanças das condições ambientais.

Painful temporomandibular disorders, self reported tinnitus, and depression are highly associated

Objetivo Investigar a associação entre disfunção temporomandibular (DTM) dolorosa, auto-relato de zumbido e níveis de depressão. Método A amostra foi composta por 224 indivíduos com idades de 18 a 76 anos. O Research Diagnostic Criteria for Temporomandibular Disorders , eixo I, foi usado para classificar a DTM e o eixo II para obtenção do auto-relato de zumbido e dos níveis de depressão. Para a análise dos dados, foi aplicado o teste odds ratio (OR) com intervalo de confiança (IC) de 95%. Resultado Somente a presença de DTM dolorosa estava significativamente associada aos níveis de depressão moderado/severo (OR=9,3, 95%; IC: 3,44-25,11). A presença concomitante de DTM dolorosa e auto-relato de zumbido aumentaram a magnitude da associação com os níveis de depressão moderado/severo (OR=16,3; 95% IC: 6,58-40,51). Conclusão Disfunção temporomandibular dolorosa, altos níveis de depressão e auto-relato de zumbido estão fortemente associados. Entretanto, o desenho do estudo não permite estabelecer uma relação causal entre essas três entidades.

Cardiovascular risk and mortality in end-stage renal disease patients undergoing dialysis: sleep study, pulmonary function, respiratory mechanics, upper airway collapsibility, autonomic nervous activity, depression, anxiety, stress and quality of life: a prospective, double blind, randomized controlled clinical trial

Background: Chronic kidney disease (CKD) is one of the most serious public health problems. The increasing prevalence of CKD in developed and developing countries has led to a global epidemic. The hypothesis proposed is that patients undergoing dialysis would experience a marked negative influence on physiological variables of sleep and autonomic nervous system activity, compromising quality of life.Methods/Design: A prospective, consecutive, double blind, randomized controlled clinical trial is proposed to address the effect of dialysis on sleep, pulmonary function, respiratory mechanics, upper airway collapsibility, autonomic nervous activity, depression, anxiety, stress and quality of life in patients with CKD. The measurement protocol will include body weight (kg); height (cm); body mass index calculated as weight/height(2); circumferences (cm) of the neck, waist, and hip; heart and respiratory rates; blood pressures; Mallampati index; tonsil index; heart rate variability; maximum ventilatory pressures; negative expiratory pressure test, and polysomnography (sleep study), as well as the administration of specific questionnaires addressing sleep apnea, excessive daytime sleepiness, depression, anxiety, stress, and quality of life.Discussion: CKD is a major public health problem worldwide, and its incidence has increased in part by the increased life expectancy and increasing number of cases of diabetes mellitus and hypertension. Sleep disorders are common in patients with renal insufficiency. Our hypothesis is that the weather weight gain due to volume overload observed during interdialytic period will influence the degree of collapsibility of the upper airway due to narrowing and predispose to upper airway occlusion during sleep, and to investigate the negative influences of haemodialysis in the physiological variables of sleep, and autonomic nervous system, and respiratory mechanics and thereby compromise the quality of life of patients.

Inducing ovulation early postpartum influences uterine health and fertility in dairy cows

The objective of the current study was to evaluate the effect of GnRH early postpartum on induction of ovulation, uterine health, and fertility in dairy cows. Holstein cows without a corpus luteum (CL) at 17 +/- 3 DIM were assigned randomly to receive i.m. GnRH (n = 245) at 17 +/- 3 and 20 +/- 3 DIM or remain as controls (n = 245). Ovaries were scanned by ultrasonography twice weekly totaling 4 examinations. Ovulation was characterized by the appearance of a CL >= 20 mm at any ultrasound or CL <20 mm in 2 consecutive examinations. Clinical and cytological endometritis were diagnosed at 35 DIM. Compared with control, GnRH increased ovulation up to 3.5 d after the last treatment (78.7 vs. 45.0%) and did not affect the prevalence of clinical endometritis (23.9 vs. 18.6%) or cytological endometritis (30.9 vs. 32.8%). Prevalence of clinical endometritis increased in cows that had calving problems (32.6 vs. 15.9%) and metritis (40.6 vs. 15.8%). Metritis increased prevalence of cytological endometritis (50.7 vs. 23.5%). Treatment with GnRH did not affect pregnancy per artificial insemination at 32 (37.6 vs. 38.6%) or 74 d after artificial insemination (35.0 vs. 31.5%), but reduced pregnancy loss (6.8 vs. 18.1%). No overall effect of GnRH treatment on hazard of pregnancy was observed; however, an interaction between GnRH treatment and ovulation showed that GnRH-treated cows that ovulated had increased hazard of pregnancy by 300 DIM compared with GnRH-treated and control cows that did not ovulate (hazard ratio = 2.0 and 1.3, respectively), but similar to control cows that ovulated (hazard ratio = 1.1). Gonadotropin-releasing hormone early postpartiim induced ovulation without affecting uterine health, but failed to improve pregnancy per artificial insemination or time to pregnancy, although it reduced pregnancy loss.

Depression and Cognitive Decline: Factors Related to Demographics and Psycho Pharmacotherapy on Elderly in Nursing Homes

Objectives: To identify the prevalence of neuropsychiatric disorders, especially DP and CD, on a sample of nursing home residents, relating this prevalence with some aspects of the demographics and psycho pharmacotherapy. Methods: 48 elders from two different nursing homes were selected. The collection of demographic and pharmacological data was made utilizing medical records. The medication was classified according to the Anatomical Therapeutic Chemical Code (ATC) criteria. The Geriatric Depression Scale (GDS 30) and the Mini Mental State Examination (MMSE) tests were utilized to determine the prevalence of DP and CD. Results: It was observed in the sample a high incidence of DP and CD among the researched elders. More schooling individuals tend to present less CD. Individuals with less CD indicatives present less symptomatology for DP. Of all the researched elders, 54,2% are submitted to psycho pharmacotherapy. Of all the consumed medicine, 16,5% belonged to the class of neuropsychiatric medicine. The medicated elders present, in average, a larger symptomatology for DP (12 points/average/GDS) than the non-medicated elders (9,9 points/average/GDS). The inverse occurs in relation to the CD indicatives. The use of psychotropics, especially in association, can have negative effects related to depression and cognition. Discussion: The pharmacotherapy, characterized for the polymedication and chronicity, especially of neuropsychiatric medicines, deserves special attention among elders, because the data suggest a significant relation between the utilization of medicines, singly or in association, and the increase of CD and DP. In addition, the data suggest that DP is a risk factor for CD and DM.

Nicotine dependence and levels of depression and anxiety in smokers in the process of smoking cessation

Background: Depression and anxiety are psychiatric disorders that are related to tobacco use and associated with dependence, the process of cessation, lapses and relapses after quitting smoking. Objective: To analyze the association of nicotine dependence with the level of anxiety and depression in patients who are in the process of smoking cessation. Methods: Cross-sectional study conducted with patients who sought the smoking cessation program in Cuiabá/MT. All the smokers enrolled from May to August 2012, participated in this study. Four instruments were applied: Socio-demographic Questionnaire, Fagerstrom test, Beck Anxiety Inventory and Beck Depression Inventory. Following bivariate analysis, using the crude prevalence ratio, with level of significance lower than 5% (p < 0.05), having as variable outcome the nicotine dependence >= 5 (Fagerstrom). The associations with p < 0.20 were selected for robust Multiple Poisson Regression (RPa). Results: Associations of Fagerstrom >= 5 with the male sex (RP = 1.15 CI 95% 1.03-1.28); number of cigarettes/day (RP = 1,33; CI 95% 1.19-1.48); and moderate/severe level of depression (RP = 1.15; CI 95% 1.04-1.28) were found. In the final model (RPa), the following variables remained associated: male gender (RPa 1.12; CI 95% 1.01-1.24), number of cigarettes/day (RPa 1.28; CI 95% 1.15-1.43) and high level of depression (RPa 1.12; CI 95% 1.01-1.23). Discussion: High level of nicotine dependence was associated significantly with the level of depression, emphasizing the association between smoking and psychiatric comorbidities.
