title: The variability of the subantarctic front and the Southern Hemisphere atmospheric jet

description: Abstract The latitudinal variations of the Subantarctic Front (SAF) and Southern Hemisphere atmospheric jet were investigated for the period of 1993-2016. Zonal wind velocity, sea surface height and temperature data were used to identify these features over the South Atlantic, South Pacific and Indian Oceans individually. During this period, the atmospheric jet migrated poleward 0.34°S decade-1 in the Atlantic, 0.28°S decade-1 in the Pacific and 0.14°S decade-1 in the Indian oceans. Previous works have shown that the poleward trend is due to the expansion of the tropical belt as a consequence of greenhouse gas increase and cooling of polar stratosphere due to ozone depletion. In addition the atmospheric jet strengthen in all three basins. The SAF represents the Antarctic Circumpolar Current northern boundary and was observed in average at 46.3°S (±0.5°) in the Atlantic, 54.3°S (±0.3°) in the Pacific and 46.6°S (±0.5°) in Indian Oceans. The SAF shows a poleward migration of 0.46°S decade-1 in the Atlantic, 0.20°S decade-1 in the Pacific and 0.27°S decade-1 in the Indian Oceans, which is attributed to the sea level increasing in the Southern Hemisphere due to thermal expansion. The SAF poleward trend is consistent with the positive trend of the Southern Annular Mode during the studied period. Moreover, the jet position is statistically significant correlated to the SAF position in each ocean basin. However, the coefficients are weak: +0.22 for the Atlantic, +0.17 for the Pacific and +0.21 for the Indian oceans. The latitudinal displacement of the SAF in the Pacific is inversely proportional to the El Niño-Southern Oscillations (ENSO). During El Niño years the SAF tend to be more poleward and during La Niña years more equatorward, with maximum correlation of 0.56, with ENSO leading by three months.

title: Considering the impact of observation error correlation in ensemble square-root Kalman filter

description: Abstract Data assimilation has been developed into an effective technology that can utilize a large number of multi-source unconventional data. It cannot only provide the initial field for the ocean numerical prediction model, but also construct the ocean reanalysis datasets and provide the design basis for the ocean observation plan. In data assimilation, the estimation of the observation error is of paramount importance, because the quality of the analysis depends on it. In general, the observation error covariance matrix is diagonal or assumed to be diagonal, which means that the observation errors are independent from one another. However, there are indeed correlations in the observation errors. A diagnostic method has been developed, which can estimate a correlated and more accurate observation error covariance matrix. The proposed method combines an ensemble square-root Kalman filter with the diagnostic method, providing an estimation of the observation error covariance matrix. In order to test the performance of the method, the numerical experiments are performed with the Lorenz 96 model and a Shallow water model. The more accurate observation error covariance matrix can be obtained to use in ensemble square-root Kalman filter by using the new method. We could find using the estimated correlated observation error in the data assimilation improves the analysis.

title: The north Brazil undercurrent and the wind driven hydrodynamics in Japaratuba submarine canyon, Brazil

description: Abstract The circulation induced by the wind and the North Brazil Undercurrent (NBU) in and surrounding the Japaratuba submarine canyon on the continental shelf of the basin of Sergipe and Alagoas is described using numerical modeling. The numerical simulations were implemented to determine the canyon influence in the local hydrodynamics and in the volume flow normal to the coast, considering several different scenarios, including a homogeneous and stratified fields of temperature and salinity. Northeast and East winds favor an upward flow in the canyon, while Southeast and South winds privilege subsidence. Winds parallel to the coast cause greater volume flow in the canyon section: 40° winds (relative to true the North, parallel to the coast) caused the highest upward flow, while winds from 215° to 220° caused the highest subsidence. On the other hand, the NBU favors subsidence motion and seems to predominate over the wind forcing.

title: Prevalence of pain and associated factors in venous ulcer patients

description: BACKGROUND AND OBJECTIVES: Pain is a very frequent symptom in venous ulcer patients and may be persistent and/or exacerbated during dressing change. Pain affects quality of life and may negatively impact wound healing. This study aimed at identifying the prevalence of pain and at evaluating major painassociated factors in venous ulcer patients.METHODS: This is a transversal study carried out in a Teaching Hospital of Natal, RN. Convenience sample was made up of 100 venous ulcer patients seen by the angiology ambulatory of this hospital. A structured interview form with socio-demographic and health characteristics, and assistance and injury characteristics was used, in addition to two questions about pain from the Medical Outcome Study Short Form 36 (SF-36). Mann-Whitney test was used to compare categorical variables. Significance level was p&lt;0.05.RESULTS: Pain was referred by 86% of evaluated patients. Patients with profession/occupation, low income and who did not smoke/drank, using compressive therapy, who were oriented about using compressive therapy and leg lifting, with minor injuries, in epithelialization stage, with no odor and without signs of infection had lower pain intensity and lower impact of pain on daily life activities.CONCLUSION: Socio-demographic factors and aspects regarding assistance and injury have influenced venous ulcer-related pain. Interventions aiming at influencing such factors might help controlling these patients' pain.

title: Pain characterization in patients with Parkinson's disease

description: BACKGROUND AND OBJECTIVES:Pain in Parkinson's disease is a very frequent complaint and may precede the diagnoses of the disease. This study aimed at evaluating pain in a group of Parkinson's disease patients from a specialized treatment center.METHODS:This is a observational study of pain in Parkinson's disease patients from the Clinicas Hospital, Federal University of Pernambuco. The convenience sample, obtained between July and August 2011, was made up of 24 individuals, being 17 males and 7 females, aged between 42 and 50 (mean=64.3) years, and 48 and 66 (mean=58.7) years, respectively. Section III of the Unified Parkinson's Disease Rating Scale, Hoehn and Yahr (HY) scale according to the stage of the disease, McGill pain questionnaire and Mini Mental State Examination were used.RESULTS:Specific body region with most frequent pain was lumbar spine (50%). Categorized regions with highest complaint percentages were: trunk (66.7%) and limbs (37.5% upper; 37.5% lower). Most patients have referred pain in a single body region, regardless of analyzing specific or categorized regions (37.5%). There has been no significant difference in proportional scores obtained by each McGill questionnaire score component. Patients with rigid-akinetic Parkinson's disease had higher number of painful body regions. The comparison among McGill indices, according to predominant symptom and according to Parkinson's disease stage (HY) scores has not shown significant differences.CONCLUSION:In our study, all Parkinson's disease patients have referred pain. Although pain is one of the most frequent non-motor symptoms, many aspects regarding Parkinson's disease-related pain need further investigation, such as which would be the best pain categorization and which methodology could better distinguish different mechanisms of different types of pain.

title: Recommendations for the use of opioids in Brazil: Part III. Use in special situations (postoperative pain, musculoskeletal pain, neuropathic pain, gestation and lactation)

description: BACKGROUND AND OBJECTIVES: The use of opioids as first and second line agents to adequately treat pain requires systematization in different clinical syndromes which course with acute pain. This study aimed at discussing recommendations for the use of opioids in acute postoperative pain, neuropathic pain, musculoskeletal pain and pain during gestation and lactation.CONTENTS: This review has addressed the use of opioids in frequent chronic and acute painful syndromes, in gestation and lactation, discussing indications, drugs used, doses, risks, complications and recommendations.CONCLUSION: Opioids for acute postoperative pain have been broadly studied and are established for minor medium and major surgeries. Recommendations for the use of opioids in neuropathic and musculoskeletal pain are restricted to second line treatment and require further discussions. Few studies have investigated the interaction of opioids with physiologic changes typical of gestation and the repercussions of the use of such agents to treat acute and chronic pain in the short and long term.
