Coastal Impacts Around Guadiaro River Mouth (Spain)

The “Port of Sotogrande” Beach (San Roque, Cadiz, Spain) has suffered significant erosion and changes since the construction of the marina and port of Sotogrande (San Roque, Cadiz, Spain). This paper reviews the dynamical processes on Guadiaro front and establishes relationship between them. It sets from a comparative evolution of the Alboran Sea Coast outlets and bays since the Little Ice Age, which shows that the Guadiaro estuary has remained functional while all other Alboran fluvial estuaries silted to son. The study shows the evidences of the coastal impacts around the mouth, even further than mouth littoral barriers, of the port infrastructures; and it provides new elements to understand the dynamical processes on the mouth and surroundings as well. That should be fundamental for shore protection along the whole coastal stretch

Genetic and pharmacological disruption of neurokinin 1 receptor function decreases anxiety-related behaviors and increases serotonergic function

Alterations in serotonin (5-hydroxytriptamine, 5-HT), norepinephrine, and γ-aminobutyric acid have been linked to the pathophysiology of anxiety and depression, and medications that modulate these neurotransmitters are widely used to treat mood disorders. Recently, the neuropeptide substance P (SP) and its receptor, the neurokinin 1 receptor (NK1R), have been proposed as possible targets for new antidepressant and anxiolytic therapies. However, animal and human studies have so far failed to provide a clear consensus on the role of SP in the modulation of emotional states. Here we show that both genetic disruption and acute pharmacological blockade of the NK1R in mice result in a marked reduction of anxiety and stress-related responses. These behavioral changes are paralleled by an increase in the firing rate of 5-HT neurons in the dorsal raphe nucleus, a major source of serotonergic input to the forebrain. NK1R disruption also results in a selective desensitization of 5-HT1A inhibitory autoreceptors, which resembles the effect of sustained antidepressant treatment. Together these results indicate that the SP system powerfully modulates anxiety and suggest that this effect is at least in part mediated by changes in the 5-HT system.

Expressão dos genes codificadores de canais de sódio Nav 1.7, Nav 1.8 e Nav 1.9 em portadores da Síndrome de Ardência Bucal

A síndrome de ardência bucal (SAB) é uma condição caracterizada pelo sintoma de ardência na mucosa oral, na ausência de qualquer sinal clínico. Sua etiologia é desconhecida e, até o momento, não dispõe de tratamento efetivo. Há entretanto características de doença neuropática que justificam investigações nesse sentido. O objetivo desse estudo foi mensurar a expressão gênica dos receptores de canais de sódio, Nav 1.7, Nav 1.8 e Nav 1.9, nos pacientes portadores de SAB. A casuística foi composta por dois grupos sendo o grupo de estudo composto por 12 pacientes portadores de SAB, selecionados através do critério estabelecido pela International Headache Society, em 2013 e o grupo controle composto por 4 pacientes não portadores de SAB. As amostras analisadas foram coletadas do dorso lingual, por meio de biópsia realizada com punch de 3 mm e profundidade de 3 mm, estas foram submetidas ao método de análise RT-PCR em tempo real. A expressividade dos genes de canais de sódio foi avaliada nos indivíduos portadores de SAB em relação aos do grupo controle, sendo esta calculada a partir da normalização dos dados da quantificação destes com os da expressão do gene constitutivo (GAPDH), pelo método de Cicle Threshold comparativo e analisados estatisticamente por meio do teste estatístico Mann-Whitnney. Observou-se o aumento da expressão gênica do Nav 1.7 (fold-change = 38.70) e diminuição da expressão gênica do Nav 1.9 (fold-change = 0.89), porém sem diferenças estatisticamente significativas entre os grupos analisados. O gene Nav 1.8 não foi expresso em nenhuma das amostras analisadas. O Nav 1.7 expressa-se tanto em neurônios nociceptivos quanto no sistema nervoso autônomo e mutações no Nav 1.9 tem sido associada a perda de percepção dolorosa. Os resultados obtidos embora não estatisticamente significativos são compatíveis com as características da doença, justificando a extensão dos estudos na linha expressão de genes codificadores dos canais de sódio em pacientes com SAB.

How can an invasive grass affect fire behavior in a tropical savanna? A community and individual plant level approach

Some invasive grasses have been reported to change fire behavior in invaded plant communities. Urochloa brizantha is an aggressive invasive grass in the Brazilian Cerrado, an ecosystem where fire is a common disturbance. We investigated the effects of U. brizantha on fire behavior in an open Cerrado physiognomy in Central Brazil. Using experimental burnings we compared fire behavior at both the community and the individual plant level in invaded (UJ) and non-invaded (NJ) areas burned in July. We also assessed the effect of fire season in invaded areas by comparing July (UJ) and October (UO) burnings. We evaluated the following variables: fuel load, fuel moisture, combustion efficiency, maximum fire temperature, flame height, and fire intensity. Additionally, we evaluated the temperatures reached under invasive and native grass tussocks in both seasons. Fuel load, combustion efficiency, and fire intensity were higher in NJ than in UJ, whilst flame height showed the opposite trend. Fuel amount and fire intensity were higher in October than in July. At the individual plant level, U. brizantha moisture was higher than that of native species, however, temperatures reaching ≥600 °C at ground level were more frequent under U. brizantha tussocks than under native grasses. At the community level, the invasive grass modified fire behavior towards lower intensity, lower burning efficiency, and higher flame height. These results provide essential information for the planning of prescribed burnings in invaded Cerrado areas.

Receipt book of Francis Kittredge, 1780

Contains instructions for preparing and administering medicine for adults and children, and generalized uses for certain ingredients, written by Dr. Francis Kittredge. Preparations include ointment for scurvy, bone ointment, nerve ointments, procedures to soothe a sore mouth and to stop excessive bleeding, and treatment to kill worms. The materials used to prepare bone ointment include fresh butter, hog fat, chamomile, garlic, and night shade, among other ingredients. The recipe for “simple nerve ointment” instructs the preparer to simmer half a pint of neet foot oil, a pint of rum, and one jell of oil of turpentine over a “gentle fire.” Kittredge writes that oil of St. John’s Wort is effective in treating swelling of the legs, for cold and aches, and for burning and scalds, while oil of Elderflower is indicated for belly aches. The manuscript is housed in a binding created by the Harvard Medical School library. Tipped into the binding is one letter from Frederick O. West, M.D., Harvard Medical School, Boston, Massachusetts, that accompanied his donation of the Kittredge receipt book to the library in 1919. There is also one letter of unknown provenance enclosed with the receipt book, which contains an inventory of the estate of Antipas Brigham, of Grafton, Massachusetts, signed by Worcester County Judge Joseph Wilder on 7 November 1749. It is unclear if this letter has any connection to Frederick O. West or Francis Kittredge.

Cognitive change processes in a group cognitive behavior therapy of depression

The present study attempted to examine the causal relationships among changes in automatic thoughts, dysfunctional attitudes, and depressive symptoms in a 12-week group cognitive behavior therapy (GCBT) program for depression. In all, 35 depressed patients attending the GCBT program were monitored with the Automatic Thoughts Questionnaire, Dysfunctional Attitudes Scale, and Beck Depression Inventory at the pre-treatment, 4th and 8th sessions, and post-treatment. The results were as follows: (1) GCBT reduces negative cognitions; (2) changes in automatic thoughts and dysfunctional attitudes lead to change in depressive symptoms; and (3) automatic thoughts play a mediating role between dysfunctional attitudes and depression. The findings taken as a whole support the Causal Cognition Model of depression. (C) 2003 Elsevier Science Ltd. All rights reserved.

Improving the physical status and quality of life of women treated for breast cancer: A pilot study of a structured exercise intervention

Background and Objectives: This pilot project assessed the acceptability of a mixed-type, moderate-intensity exercise programme following breast cancer treatment, and the impact on presence of lymphoedema, fitness, body composition, fatigue, mood and quality of life. Methods: Ten women completed the programme and measures of fitness (submaximal ergometer test), body composition (bio-electrical impedance), lympoedema (bio-electrical impedance and arm circumferences), fatigue (revised Piper Fatigue Scale), mood (Hospital Anxiety and Depression Scale), quality of life (FACT-B) and general well-being, at baseline, completion of the programme, and 6-week and 3-month follow-up. Results: Participation in the programme caused no adverse effect on the presence of lymphoedema. There was a trend towards reduction in fatigue and improved quality of life across the testing phases. Women rated the programme extremely favourably, citing benefits of the support of other women, trained guidance, and the opportunity to experience different types of exercise. Conclusions: A mixed-type, moderate-intensity exercise program in a group format is acceptable to women following breast cancer treatment, with the potential to reduce fatigue and improve quality of life, without exacerbating or precipitating lymphoedema. This pilot work needs to be confirmed in larger randomised studies. (C) 2004 Wiley-Liss, Inc.

How does mental health status relate to accessibility and remoteness?

Objective: To determine whether mental illness is associated with accessibility and remoteness. Design: A cross-sectional, population-based, computer-assisted telephone interview survey, stratified by Accessibility and Remoteness Index of Australia (ARIA) categories. Setting: Secondary analysis of data collected from 2545 South Australian adults in October and November 2000. Outcome measures: Psychological distress and depression as determined by the Kessler 10 Psychological Distress Scale, the SF-12 measure of health status, and self-reported mental illness diagnosed by a doctor in the previous 12 months. Results: Overall, mental illness prevalence estimates were similar using the three measures of psychological distress (10.5%), clinical depression (12.9%) and self-reported mental health problem (12.7%). For each measure, there was no statistically significant variation in prevalence across ARIA categories, except for a lower than expected prevalence of depression (7.7%) in the accessible category. There was no trend suggesting higher levels of mental illness among residents of rural and remote regions. Conclusions: The prevalence rates of psychological distress, depression and self-reported mental illness are high. However, we found no evidence that the prevalence of these conditions varies substantially across ARIA categories in South Australia. This finding may challenge existing stereotypes about higher levels of mental illness outside metropolitan Australia.

How to recognize and manage psychological distress in cancer patients

Psychological distress is common in cancer patients, however, it is often unrecognized and untreated. We aimed to identify barriers to cancer patients expressing their psychological concerns, and to recommend strategies to assist oncologists to elicit, recognize, and manage psychological distress in their patients. Medline, Psychlit, and the Cochrane databases were searched for articles relating to the detection of emotional distress in patients. Patients can provide verbal and non-verbal information about their emotional state. However, many patients may not reveal emotional issues as they believe it is not a doctor's role to help with their emotional concerns. Moreover, patients may normalize or somatize their feelings. Anxiety and depression can mimic physical symptoms of cancer or treatments, and consequently emotional distress may not be detected. Techniques such as active listening, using open questions and emotional words, responding appropriately to patients' emotional cues, and a patient-centred consulting style can assist in detection. Screening tools for psychological distress and patient question prompt sheets administered prior to the consultation can also be useful. In conclusion, the application of basic communication techniques enhances detection of patients' emotional concerns. Training oncologists in these techniques should improve the psychosocial care of cancer patients.

Study of the integrated cognitive model of depression among Latin-Americans

Objective: The objective of the present study is to test the validity of the integrated cognitive model (ICM) of depression proposed by Kwon and Oei with a Latin-American sample. The ICM of depression postulates that the interaction between negative life events with dysfunctional attitudes increases the frequency of negative automatic thoughts, which in turns affects the depressive symptomatology of a person. This model was developed for Western Europeans such as Americans and Australians and the validity of this model has not been tested on Latin-Americans. Method: Participants were 101 Latin-American migrants living permanently in Brisbane, including people from Chile, El Salvador, Nicaragua, Argentina and Guatemala. Participants completed the Beck Depression Inventory, the Dysfunctional Attitudes Scale, the Automatic Thoughts Questionnaire and the Life Events Inventory. Alternative or competing models of depression were examined, including the alternative aetiologies model, the linear mediational model and the symptom model. Results: Six models were tested and the results of the structural equation modelling analysis indicated that the symptom model only fits the Latin-American data. Conclusions: Results show that in the Latin-American sample depression symptoms can have an impact on negative cognitions. This finding adds to growing evidence in the literature that the relationship between cognitions and depression is bidirectional, rather than unidirectional from cognitions to symptoms.

Factor structure of the Mood and Anxiety Symptom Questionnaire does not generalize to an anxious/depressed sample

Objective: The tripartite model of anxiety and depression has been proposed as a representation of the structure of anxiety and depression symptoms. The Mood and Anxiety Symptom Questionnaire (MASQ) has been put forwards as a valid measure of the tripartite model of anxiety and depression symptoms. This research set out to examine the factor structure of anxiety and depression symptoms in a clinical sample to assess the MASQ's validity for use in this population. MethodsThe present study uses confirmatory factor analytic methods to examine the psychometric properties of the MASQ in 470 outpatients with anxiety and mood disorder. Results: The results showed that none of the previously reported two-factor, three-factor or five-factor models adequately fit the data, irrespective of whether items or subscales were used as the unit of analysis. Conclusions: It was concluded that the factor structure of the MASQ in a mixed anxiety/depression clinical sample does not support a structure consistent with the tripartite model. This suggests that researchers using the MASQ with anxious/depressed individuals should be mindful of the instrument's psychometric limitations.
