Neuroimaging of depression in Parkinson's disease: a review.

BACKGROUND: Depression is the most common psychiatric manifestation in patients with Parkinson's disease (PD). In addition, depressive symptoms may be considered to be a prodromal manifestation of PD. In recent years, the association between PD and depression has been the focus of neuroimaging studies using functional and structural techniques. METHODS: The aim of this study was to review the main neuroimaging studies assessing the comorbidity between depression and PD. Literature searches were conducted to find the major neuroimaging studies that consider primarily the comorbidity between depression and PD using the indices Web of Science and Lilacs. RESULTS: In total, 296 papers were identified, and 18 of these studies were selected for the current review. The principal neuroimaging technique used was SPECT. The structural neuroimaging studies that have evaluated the impact of current or previous bouts of depression on the neurodegenerative process of PD are scarce and inclusive. The instruments that were used to evaluate depression differed among the studies. Several brain regions appear to be involved in depression, particularly the limbic system and the basal ganglia. In addition, the serotonergic, dopaminergic, and noradrenergic systems also appear to be associated with depressive symptoms in PD. CONCLUSION: Several brain regions and neurotransmitter systems are involved in depression in PD; however, the variety of criteria used to evaluate depressive symptoms precludes more specific conclusions.

The Impact of Violence on the Anxiety Levels of Healthcare Personnel During the COVID-19 Pandemic.

Introduction: The COVID-19 pandemic stressed the importance of healthcare personnel. However, there is evidence of an increase in violence against them, which brings consequences, such as anxiety. The aim of this study was to analyze the anxiety levels of health professionals who have or not suffered violence during the COVID-19 pandemic, and verify the variables associated with the risk of starting to take medication for anxiety. Methods: We assessed the anxiety profile of health professionals in Brazil through an online questionnaire, using the Generalized Anxiety Disorder 7-item Scale (GAD-7), in relation to groups of participants who have or not suffered violence during the COVID-19 pandemic. We used Cronbach's alpha reliability coefficient to check the consistency of the responses, and the effect size using the r coefficient. Principal Component Analysis was used to verify the differences in anxiety scores between the two groups. Logistic regression analysis was also used to verify the variables associated with the risk of starting medication for anxiety and considered statistically significant when p < 0.05. Results: A total of 1,166 health professionals participated in the study, in which 34.13% had a normal anxiety profile, 40.14% mild, 15.78% moderate, and 9.95% severe. The mean score of the sum of the GAD-7 was 7.03 (SD 5.20). The group that suffered violence had a higher mean (8.40; SD 5.42) compared to the group that did not (5.70; SD 4.60). In addition, the median between both groups was significantly different (7.0 vs. 5.0; p < 0.01). Approximately 18.70% of the participants reported having started taking medication to treat anxiety during the pandemic. The factors that increased the chances of these professionals starting medication for anxiety p < 0.05 were having suffered violence during the pandemic (OR 1.97; 95% CI 1.42-2.77), being nurses (OR 1.61; 95% CI 1.04-2.47) or other types of health professionals (OR 1.58; 95% CI 1.04-2.38), and having a mild (OR 2.11; 95% CI 1.37-3.34), moderate (OR 4.05; 95% CI 2.48-6.71) or severe (OR 9.08; 95% CI 5.39-15.6) anxiety level. Conclusion: Brazilian healthcare professionals who have suffered violence during the pandemic have higher anxiety scores and higher risk to start taking anxiety medication.

Gravidez após cirurgia bariátrica / Pregnancy following bariatric surgery

A obesidade é uma condição crônica que tem se tornado prevalente ao redor do mundo. Os tratamentos clínicos incluem dieta, exercícios, alteração comportamental e uso de medicações. A cirurgia deve ser reservada para os pacientes obesos mórbidos que não respondem às terapias não invasivas para perda de peso. Durante as últimas décadas, a cirurgia bariátrica se expandiu rapidamente e cada vez mais mulheres jovens estão procurando esta forma de tratamento, o que pode causar um aumento no número de gestações após a perda de peso. A gravidez após a cirurgia bariátrica nos traz uma série de questionamentos e preocupações a respeito da gestante e de seu feto. A suplementação nutricional e a monitorização intensiva antes, durante e após a gravidez podem ajudar a evitar complicações relacionadas à nutrição e melhorar a saúde materno-fetal, e os obstetras devem estar preparados para lidar com esse tipo de paciente, que será cada vez mais freqüente na prática diária em um futuro próximo.
