Clozapine use decreases the number of hospitalizations per year in patients with treatment-resistant schizophrenia.

For years, the management of schizophrenia has represented a challenge for clinicians, with antipsychotic treatments usually resulting in relapses and new hospitalizations. Clozapine has been shown to be an effective medication for treatment-resistant schizophrenia (TRS), but is currently underused due to its potential side effects. Nevertheless, research has suggested that clozapine reduces future hospitalizations in patients with TRS. This study aims to verify the rates of hospitalizations in patients with TRS under long-term use of clozapine. We retrospectively analyzed clinical data from 52 individuals with TRS before and after the use of clozapine. The mean duration of treatment with and without clozapine was 6.6 (± 3.9) and 8.5 years (± 6.6), respectively. Patients had a median of 0.5 (0.74) hospitalizations per year before the use of clozapine and 0 (0.74) hospitalizations after it (p = 0.001). Therefore, the use of clozapine resulted in an expected reduction in the number of hospitalizations per year in individuals with TRS

Lung Cancer and the COVID-19 pandemic: Recommendations from the Brazilian Thoracic Oncology Group

New cases of the novel coronavirus disease 2019 (COVID-19), also known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), continue to rise worldwide following the declaration of a pandemic by the World Health Organization (WHO). The current pandemic has completely altered the workflow of health services worldwide. However, even during this critical period, patients with other diseases, like cancer, need to be properly treated. A few reports have shown that mortality due to SARS-CoV-2 is higher in elderly patients and those with other active comorbidities, including cancer. Patients with lung cancer are at risk of pulmonary complications from COVID-19, and as such, the risk/benefit ratio of local and systemic anticancer treatment has to be considered. For each patient, several factors, including age, comorbidities, and immunosuppression, as well as the number of hospital visits for treatment, can influence this risk. The number of cases is rising exponentially in Brazil, and it is important to consider the local characteristics when approaching the pandemic. In this regard, the Brazilian Thoracic Oncology Group has developed recommendations to guide decisions in lung cancer treatment during the SARS-CoV-2 pandemic. Due to the scarcity of relevant data, discussions based on disease stage, evaluation of surgical treatment, radiotherapy techniques, systemic therapy, follow-up, and supportive care were carried out, and specific suggestions issued. All recommendations seek to reduce contagion risk by decreasing the number of medical visits and hospitalization, and in the case of immunosuppression, by adapting treatment schemes when possible. This statement should be adjusted according to the reality of each service, and can be revised as new data become available

Long-term treatment with clozapine and verbal memory performance in schizophrenia

Clozapine is more efficacious than first-generation antipsychotics for positive and negative symptoms, although it is related with serious adverse effects. Because of this profile, it could also have an impact on cognition. Therefore, we evaluated learning ability of 31 treatment-resistant individuals with SZ using clozapine uninterruptedly for 18.23 ± 4.71 years and 26 non-treatment-resistant using other antipsychotics that never used clozapine. Long-term treatment with clozapine did not improve verbal learning ability better than other antipsychotics. Although clozapine has a unique profile for reducing clinical symptoms, it may not have an additional benefit for cognition when started later on the course of schizophrenia

Hepatitis E, Schistosomiasis and Echinococcosis : prevalence in a cohort of pregnant migrants in Germany and their influence on fetal growth restriction

Background: Infections, as well as adverse birth outcomes, may be more frequent in migrant women. Schistosomiasis, echinococcosis, and hepatitis E virus (HEV) seropositivity are associated with the adverse pregnancy outcomes of fetal growth restriction and premature delivery. Methods: A cohort study of 82 pregnant women with a history of migration and corresponding delivery of newborns in Germany was conducted. Results: Overall, 9% of sera tested positive for anti-HEV IgG. None of the patients tested positive for anti-HEV IgM, schistosomiasis, or echinococcus serology. Birth weights were below the 10th percentile for gestational age in 8.5% of the neonates. No association between HEV serology and fetal growth restriction (FGR) frequency was found. Conclusions: In comparison to German baseline data, no increased risk for HEV exposure or serological signs of exposure against schistosomiasis or echinococcosis could be observed in pregnant migrants. An influence of the anti-HEV serology status on fetal growth restriction could not be found.Publikationsfonds ML

Implementando testes de mutação somática em ambiente clínico: recomendações de um painel de especialistas

There has been a rapid increase in the volume of genomic data gathered from different cancers, this has helped to develop new tumor classifications as well as to select better tailored therapies for the patients. Some of the genomic markers identified are also prognostic and predictive factors. Additionally, many technologies have been used to investigate these alterations, each with different benefits and caveats. The Genomics Committee from the Sociedade Brasileira de Oncologia Clínica (SBOC) put together a group of specialists, from different regions of Brazil that work both in the private and public scenario, to gather and organize the information regarding the utility of somatic mutation testing in solid tumors. This special article summarizes their recommendations on how to better incorporate this information into clinical practice
