"Non-metastatic, Castration-resistant Prostate Cancer: Diagnostic and Treatment Recommendations by an Expert Panel from Brazil".

INTRODUCTION: Non-metastatic, castration-resistant prostate cancer (nmCRPC) is an important clinical stage of prostate cancer, prior to morbidity and mortality from clinical metastases. In particular, the introduction of novel androgen-receptor signaling inhibitors (ARSi) has changed the therapeutic landscape in nmCRPC. Given recent developments in this field, we update our recommendations for the management of nmCRPC. METHODS: A panel of 51 invited medical oncologists and urologists convened in May of 2021 with the aim of discussing and providing recommendations regarding the most relevant issues concerning staging methods, antineoplastic therapy, osteoclast-targeted therapy, and patient follow-up in nmCRPC. Panel members considered the available evidence and their practical experience to address the 73 multiple-choice questions presented. RESULTS: Key recommendations and findings include the reliance on prostate-specific antigen doubling time for treatment decisions, the absence of a clear preference between conventional and novel (i.e., positron-emission tomography-based) imaging techniques, the increasing role of ARSis in various settings, the general view that ARSis have similar efficacy. Panelists highlighted the slight preference for darolutamide, when safety is of greater concern, and a continued need to develop high-level evidence to guide the intensity of follow-up in this subset of prostate cancer. DISCUSSION: Despite the limitations associated with a consensus panel, the topics addressed are relevant in current practice, and the recommendations can help practicing clinicians to provide state-of-the-art treatment to patients with nmCRPC in Brazil and other countries with similar healthcare settings.

Asthma control, social jetlag, and sleep impairment in high school adolescents.

INTRODUCTION: Social jetlag is associated with several negative health outcomes, but its impact on asthma control has not been previously investigated. Although impaired sleep is common in asthma, studies on the relationship between sleep quality, social jetlag and asthma control in adolescents are scarce. OBJECTIVE: To investigate the relationship between asthma control and sleep quality, sleep-wake pattern and excessive daytime sleepiness in adolescents. METHODS: This was a cross-sectional study of 1457 Brazilian high-school adolescents. Asthma was identified using the International Study of Asthma and Allergies in Childhood questionnaire, and disease control was measured by the Asthma Control Test. Sleep-wake pattern and social jetlag were assessed by the Munich Chrono-Type Questionnaire; sleep quality, by the Pittsburgh Sleep Quality Index; and daytime sleepiness, by the Epworth Sleepiness Scale. RESULTS: Asthma was present in 250 (17.2%) participants and was classified as uncontrolled in 120 (47.9%). Both uncontrolled and controlled asthma groups, compared with non-asthmatics, had worse sleep quality (81.7% vs 77.4% vs 56.5%; p < 0.001) and excessive daytime sleepiness (EDS: 56.2% vs 56.5% vs 39.2%; p < 0.001). On average, adolescents with uncontrolled asthma, compared to non-asthmatics, showed later sleep onset (mean ± SD: 23:54pm ± 1 h:45min vs 23:20pm ± 1 h:27min; p = 0.002) and shorter sleep duration (5.7 h ± 1.8 h vs 6.3 h ± 1.4 h; p = 0.002) on school days. No significant difference in social jetlag was found among the three groups. CONCLUSIONS: Asthma is associated with EDS and poor-quality sleep in adolescents. Social jetlag is common in these subjects and is not related to the presence and control of asthma.

Impactos da COVID-19 nos pacientes oncológicos: uma revisão sistemática / Impacts of COVID-19 on cancer patients: a systematic review

Introdução: Com a pandemia de coronavírus os pacientes oncológicos, que estão em tratamentos, nos quais a maioria são imunossupressores, se tornaram um grupo muito suscetível a formas graves da infecção. Logo, como forma de proteção e prevenção, a realização de exames de rastreio no ambiente hospitalar foi restringida, atrasando diversos diagnósticos e comprometendo a eficácia de tratamentos. Objetivos: Analisar a produção científica acerca do tema câncer e COVID-19, a fim de contribuir com informações sobre o assunto. Métodos: Revisão sistemática da literatura nas bases de dados SciELO, LILACS e PubMed. Os descritores utilizados foram "câncer" AND "COVID-19" de acordo com o Medical Subject Headings (MeSH) e seus equivalentes para a língua portuguesa, conforme os descritores de Ciências da Saúde (DeCS). Foram incluídos artigos originais em inglês e português, sem delimitação temporal. Resultados: Foram encontrados 1.606 artigos e, após utilizar os critérios de inclusão e exclusão, nove foram incluídos para análise na revisão. Dentre os temas centrais abordados pelos estudos selecionados estão o impacto da pandemia em algumas áreas de acompanhamento do paciente oncológico, como: tratamento, telemedicina, diminuição de funcionários no atendimento ao paciente com câncer, diminuição dos ensaios clínicos, redução dos recursos financeiros e apoio psicológico a essa população. Conclusão: A pandemia afetou diretamente o modo de vida desse grupo, que sofreu com uma redução no atendimento médico e nos recursos dispostos a eles. Portanto, nota-se a necessidade de prestar um cuidado mais específico a esses pacientes em situação tão delicada durante a pandemia.

Introduction: During the coronavirus pandemic, oncological patients, who are undergoing treatments in which the majority are immunosuppressant, have become a group very susceptible to severe forms of the infection. Therefore, as a form of protection, their going to hospital environments were restricted, delaying diagnosis and compromising the effectiveness of treatments. Objectives: This study aims to analyze the scientific about the production of the theme cancer and COVID-19 in order to contribute with informations on the subject. Methods: Systematic review of literature using the SciELO, LILACS and PubMed. The following keywords were used: "cancer" AND "COVID-19" according to the Medical Subject Headings (MeSH) and their translation to the Portuguese. Studies in English and Portuguese from inception were included. Results: 1,606 studies were screened and 9 were included in the systematic review after using the inclusion and exclusion criterias. Among the central themes addressed by the selected studies are the pandemic impacts in areas of monitoring oncological patients, such as: treatment, telemedicine, reduction of employees in the care of cancer patients, reduction of clinical trials, reduction of financial resources, and psychological support to that population. Conclusion: The pandemic directly affected the way of life of this group, which suffered from a reduction in medical care and the resources available to them. Therefore, there is a need to provide more specific care to these patients in such a delicate situation during the pandemic.

Consensus for Treatment of Metastatic Castration-Sensitive Prostate Cancer: Report From the First Global Prostate Cancer Consensus Conference for Developing Countries (PCCCDC).

PURPOSE: International guideline recommendations may not always be extrapolated to developing countries where access to resources is limited. In metastatic castration-sensitive prostate cancer (mCSPC), there have been successful drug and imaging advancements that were addressed in the Prostate Cancer Consensus Conference for Developing Countries for best-practice and limited-resource scenarios. METHODS: A total of 24 out of 300 questions addressed staging, treatment, and follow-up for patients with mCSPC both in best-practice settings and resource-limited settings. Responses were compiled and presented in percentage of clinicians supporting each response. Questions had 4-8 options for response. RESULTS: Recommendations for staging in mCSPC were split but there was consensus that chest x-ray, abdominal and pelvic computed tomography, and bone scan should be used where resources are limited. In both de novo and relapsed low-volume mCSPC, orchiectomy alone in limited resources was favored and in relapsed high-volume disease, androgen deprivation therapy plus docetaxel in limited resources and androgen deprivation therapy plus abiraterone in high-resource settings were consensus. A 3-weekly regimen of docetaxel was consensus among voters. When using abiraterone, a regimen of 1,000 mg plus prednisone 5 mg/d is optimal, but in limited-resource settings, half the panel agreed that abiraterone 250 mg with fatty foods plus prednisone 5 mg/d is acceptable. The panel recommended against the use of osteoclast-targeted therapy to prevent osseous complications. There was consensus that monitoring of patients undergoing systemic treatment should only be conducted in case of prostate-specific antigen elevation or progression-suggestive symptoms. CONCLUSION: The treatment recommendations for most topics addressed differed between the best-practice setting and resource-limited setting, accentuating the need for high-quality evidence that contemplates the effect of limited resources on the management of mCSPC.

Advanced renal cell carcinoma (RCC) management: an expert panel recommendation from the Latin American Cooperative Oncology Group (LACOG) and the Latin American Renal Cancer Group (LARCG).

PURPOSE: The outcome of RCC has improved considerably in the last few years, and the treatment options have increased. LACOG-GU and LARCG held a consensus meeting to develop guidelines to support the clinical decisions of physicians and other health professionals involved in the care of RCC patients. METHODS: Eighty questions addressing relevant advanced RCC treatments were previously formulated by a panel of experts. The voting panel comprised 26 specialists from the LACOG-GU/LARCG. Consensus was determined as 75% agreement. For questions with less than 75% agreement, a new discussion was held, and consensus was determined by the majority of votes after the second voting session. RESULTS: The recommendations were based on the highest level of scientific evidence or by the opinion of the RCC experts when no relevant research data were available. CONCLUSION: This manuscript provides guidance for advanced RCC treatment according to the LACOG-GU/LARCG expert recommendations.

Renal cell cancer treatment: an expert panel recommendation from the Latin American cooperative group-genitourinary and the Latin American renal cancer group: focus on surgery.

BACKGROUND: Renal cell cancer (RCC) is one of the 10 most common cancers in the world, and its incidence is increasing, whereas mortality is declining only in developed countries. Therefore, two collaborative groups, The Latin American Oncology Cooperative Group-Genitourinary Section (LACOG-GU) and the Latin American Renal Cancer Group (LARCG), held a consensus meeting to develop this guideline. METHODS: Issues (134) related to the treatment of RCC were previously formulated by a panel of experts. The voting panel comprised 26 specialists (urologists and medical oncologists) from the LACOG-GU/LARCG. A consensus was reached if 75% agreement was achieved. If there was less concordance, a new discussion was undertaken, and a consensus was determined by the most votes after a second voting session. RESULTS: The expert meeting provided recommendations that were in line with the global literature; 75.0% of the recommendations made by the panel of experts were evidence-based level A, 22.5% of the recommendations were level B, and 2.5% of the recommendations were level D. CONCLUSIONS: This review suggests recommendations for the surgical treatment of RCC according to the LACOG-GU/LARCG experts.

Relationship of Helicobacter pylori seroprevalence with the occurrence and severity of psoriasis.

BACKGROUND:: Psoriasis is a chronic inflammatory disease that affects the skin and joints and has a multifactorial etiology. Recently, it has been suggested that Helicobacter pylori infection may contribute as a trigger for the development of the disease. OBJECTIVES:: To determine the prevalence of H. pylori seropositivity in patients with psoriasis and to evaluate the relation between disease severity and H. pylori infection. METHODS:: H. pylori infection was assessed in psoriatic patients and controls by using H. pylori IgG quantitative enzyme immunoassay (ELISA test). The patients were classified according to the severity of the disease (PASI score). RESULTS:: One hundred and twenty six patients with psoriasis (73 females and 53 males); mean age 50.48 years; 65 patients (51.59%) had severe psoriasis, 40 (31.75%) moderate psoriasis and 21 (16.67%) mild psoriasis. Twenty one healthy volunteers included as a control group, mean age of 41.05 years, 13 females and 8 males. One hundred and eleven patients with psoriasis tested serologically, 80 (72.07%) were seropositive compared with 7 positive volunteers (33.33%; P=0.002). Forty-nine (75.38%) patients with severe psoriasis were positive, 25 (62.50%) with moderate psoriasis were positive and 6 (28.57%) with mild psoriasis were positive (P=0.045). Study limitations: none. CONCLUSIONS:: H. pylori infection influences the development of psoriasis and severity of the disease.
