Small area variations in non-affective first-episode psychosis: the role of socioeconomic and environmental factors.

BACKGROUND: There is strong evidence supporting the association between environmental factors and increased risk of non-affective psychotic disorders. However, the use of sound statistical methods to account for spatial variations associated with environmental risk factors, such as urbanicity, migration, or deprivation, is scarce in the literature. METHODS: We studied the geographical distribution of non-affective first-episode psychosis (NA-FEP) in a northern region of Spain (Navarra) during a 54-month period considering area-level socioeconomic indicators as putative explanatory variables. We used several Bayesian hierarchical Poisson models to smooth the standardized incidence ratios (SIR). We included neighborhood-level variables in the spatial models as covariates. RESULTS: We identified 430 NA-FEP cases over a 54-month period for a population at risk of 365,213 inhabitants per year. NA-FEP incidence risks showed spatial patterning and a significant ecological association with the migrant population, unemployment, and consumption of anxiolytics and antidepressants. The high-risk areas corresponded mostly to peripheral urban regions; very few basic health sectors of rural areas emerged as high-risk areas in the spatial models with covariates. DISCUSSION: Increased rates of unemployment, the migrant population, and consumption of anxiolytics and antidepressants showed significant associations linked to the spatial-geographic incidence of NA-FEP. These results may allow targeting geographical areas to provide preventive interventions that potentially address modifiable environmental risk factors for NA-FEP. Further investigation is needed to understand the mechanisms underlying the associations between environmental risk factors and the incidence of NA-FEP.

Thoracic surgery in Spain.

In this manuscript, we briefly report on the Spanish health care system and the current situation of Thoracic Surgery in the country. Our surgical speciality is approached in terms of national spread of thoracic units, education, technological development, and other relevant aspects. Thoracic Surgery national workforce is also reviewed and compared to sister specialities. Prospects and authors' recommendations for development are included. Total cost of public health care expenditure in Spain represents 9% of the gross domestic product (GDP) and the National Health System is included in the top ten more efficient systems in the World. Thoracic Surgery in Spain is an independent medical speciality. The access to training in accredited hospitals is uniformly regulated all around the country and represents the official and only route to certified medical specialization. 0.5 certified specialists in Thoracic Surgery per 100,000 habitants are working in the country, half of them being female in the age subset of 30-39. Currently, more than half of all anatomical resection in the country are performed via VATS. Seven centres are currently accredited by the Ministry of Health for lung transplantation, and the current rate of lung transplants is 7.1 per million of population. To note is the success of the non-heart-beating donors program developed in recent years. Three national professional and scientific societies are gathering most Spanish thoracic surgeons and promoting cooperative multidisciplinary studies on lung cancer and surgical techniques such are video-assisted and robotic lung resection. Implementing a national database of thoracic surgical procedures would be advisable to promote continuous clinical quality improvements.

Differences between suicide attempts and other psychiatric hospital emergencies.

INTRODUCTION: In Spain, a comparative research study between those patients treated for suicide attempt and others treated by any other reason hasn't been found. The aim of this study is to describe the differences between both types of patients in relation to sociodemographic and clinic variables together with the adverse vital events and the suicidal ideation. METHODOLOGY: A descriptive, multicentric and case-controlled study carried out in psychiatric hospital emergencies where 207 patients had been evaluated for a suicidal attempt (cases) and 233 were also evaluated by any other reasons (checkings). RESULTS: The cases presented a larger percentage of previous suicide attempts (45.4% vs. 30.0%; p=0.001) and a lower rates of prior emergency care (55.6% vs. 65.7%; p=0.030) of a history of mental disorder (77.8% vs. 86.7%; p=0.014) and follow-up in mental health. The 31.8% (n=74) exhibited suicidal ideation at the time of care and the 61.4% (n=143) expressed their desire to die when questioned. CONCLUSIONS: Neither a specific sociodemographic nor clinic profile of those who try to commit suicide has been found. But a high percentage of patients with suicidal ideation were identified in people treated for other reasons. The results emphasize the need to consider and evaluate the ideation of death and the risk of suicide in all the patients treated in psychiatric hospital emergencies.

Are previous suicide attempts a risk factor for completed suicide?

BACKGROUND: A previous suicide attempt is a clinically relevant factor for completed suicide. In this paper people who committed suicide on their first attempt are compared with those who did so after previous attempts. METHOD: A review of the Computerised Clinical Histories in the Navarro Health Service-Osasunbidea (2010-2013) in Spain. RESULTS: Of the 166 cases, 31.9% (n = 53) presented at least one prior attempt. Of these 53, 65.3% modified the method of suicide. Women presented significantly more attempts (χ2 = 14.3; df = 3; p = .002). Three sub-samples were identified according to the attempts and diagnoses. The diagnoses of personality disorders (90.9%; n = 10) and women under 51 years of age with a diagnosis of affective, anxiety, or substance abuse disorders (82.4%; n = 14) presented the highest numbers of attempts. People without a psychiatric diagnosis and with psychotic or organic mental disorders presented the smallest proportion of attempts (13.2%; n = 10) together with people over 51 years of age diagnosed with affective, anxiety, or substance abuse disorders (22.5%; n = 9). CONCLUSIONS: Prior attempts are suicide risk factors only in specific clinical sub-samples. Prevention and intervention programs should consider these results.

Modulation of monocyte chemoattractant protein-1 expression by ischaemic preconditioning in a lung autotransplant model.

OBJECTIVES: Monocyte chemoattractant protein-1 (MCP-1) is believed to play a crucial role in lung ischaemia-reperfusion injury (LIRI). Ischaemic preconditioning (IP) has been shown to protect several organs from ischaemia-reperfusion (IR) injury, although less is known about IP's effect on MCP-1 modulation. The objective of this study was to investigate IP's effect on MCP-1 expression in lung tissue and its relationship with oxidative stress and proinflammatory cytokine production in an experimental LIRI model. METHODS: Two groups (IP and control groups) of seven large white pigs underwent a lung autotransplant (left pneumonectomy, ex situ superior lobectomy and lower lobe reimplantation). Before pneumonectomy was performed in the study group, IP was induced with two cycles of 5 min of left pulmonary artery occlusion with a 5 min interval of reperfusion between the two occlusions. Blood samples and lung biopsies were obtained at prepneumonectomy (PPn), at prereperfusion (PRp) and up to 30 min after reperfusion of the implanted lobe (Rp-10' and Rp-30'). Haemodynamic and blood-gas measurements, evaluation of oxidative stress in lung tissue and MCP-1, tumour necrosis factor-α (TNF-α) and IL-1 protein and mRNA measurements in lung tissue were performed. Nonparametric tests were used to compare differences between groups. Data are expressed as mean ± SEM. RESULTS: In control lungs, MCP-1 protein levels were found to be higher at PRp, Rp-10' and Rp-30' than at PPn (0.59 ± 0.1 vs. 0.21 ± 0.05, 0.47 ± 0.01 vs. 0.21 ± 0.05 and 0.56 ± 0.01 vs. 0.21 ± 0.05, respectively; P < 0.05). These differences were not evident in the IP group. MCP-1 levels at PRp, Rp-10' and Rp-30' were significantly higher in the control group than in the IP group (0.59 ± 0.1 vs. 0.15 ± 0.02, 0.47 ± 0.01 vs. 0.13 ± 0.01 and 0.56 ± 0.01 vs. 0.27 ± 0.01, respectively; P < 0.05). MCP-1, TNF-α and IL-1 mRNA expressions were lower at PRp, Rp-10' and Rp-30' (control vs. IP group, P < 0.05) when IP was carried out. Lipid peroxidation metabolites and myeloperoxidase activity increase in lung tissue were prevented by IP. CONCLUSIONS: In this model, LIRI induced the expression of MCP-1 and the proinflammatory proteins TNF-α and IL-1 in control lungs. IP significantly reduced the expression of these chemokines and cytokines. These features may explain the reduction of oxidative stress observed with IP.

The effects of anesthetic preconditioning with sevoflurane in an experimental lung autotransplant model in pigs.

BACKGROUND: Ischemia-reperfusion lung injury is doubly important in thoracic surgery because of the associated ventilation damage to 1 lung. In this study we evaluated the cytoprotective effects of sevoflurane in a pulmonary autotransplant model in pigs. METHODS: Twenty Large White pigs undergoing pneumonectomy plus lung autotransplant were divided into 2 10-member groups on the basis of the anesthetic received (propofol or sevoflurane). Proinflammatory mediators, oxidative stress, nitric oxide metabolism, and hemodynamic and blood variables were measured at 5 different time points. RESULTS: There was an increase of oxidative stress markers and proinflammatory mediators in the propofol group, whereas the hemodynamic variables were similar in both groups. CONCLUSIONS: We demonstrated that sevoflurane decreased the inflammatory response and oxidative stress in a live ischemia-reperfusion lung model.
