Clinical presentation and in-hospital prognosis of lung cancer patients presenting with suspected and confirmed COVID-19

We sought to compare the clinical presentation and prognosis of patients with lung cancer and confirmed COVID-19 infection to those with negative RT-PCR SARS-CoV-2 results. We included patients with confirmed lung cancer and suspected COVID-19 who presented to the emergency department. The primary outcome was in-hospital mortality and secondary outcomes included admission to intensive care unit (ICU) or mechanical ventilation. We analyzed the characteristics according to RT-PCR results and primary outcome. We constructed a logistic regression for each RT-PCR result group to find potential predictors of the primary outcome. Among 110 individuals with confirmed lung cancer (65±9 years, 51% male), 38 patients had positive RT-PCR and 72 patients had negative RT-PCR. There was no difference between groups for any clinical characteristic or comorbidities though individuals with confirmed COVID-19 had higher functionality in the ECOG scale. Leucocytes and lymphocytes were lower in individuals with positive tests. The primary outcome occurred in 58 (53%) individuals, 37 (34%) were admitted to the ICU, and 29 (26%) required mechanical ventilation. Although mortality was similar between the two groups, individuals with confirmed COVID-19 were significantly more likely to be admitted to the ICU or receive mechanical ventilation. Only lower lymphocytes and higher CRP were significantly associated with higher mortality. The clinical presentation of COVID-19 in lung cancer is not sufficient to identify higher or lower probability groups among symptomatic individuals, the overall mortality is high irrespective of RT-PCR results, and lymphopenia on admission was associated with the diagnosis and prognosis for COVID-19.

Anticorpos contra vírus do grupo da língua azul em caprinos e ovinos do sertão de Pernambuco e inferências sobre sua epidemiologia em regiões semiáridas / Antibodies against bluetongue-virus group in goats and sheep from Pernambuco state and inferences on bluetongue epidemiology under tropical conditions

The prevalence of antibodies against bluetongue virus was investigated in 41 dairy goats and 40 sheep herds in the semi-arid region of Pernambuco state and the conditions for insect Culicoides maintenance, considering climate dynamics and vector competence, were evaluated. The percents of seropositive herds in agar gel immunodiffusion test for bluetongue virus group were 24 for goats and 27.5 for sheep. The estimated prevalences of seropositive animals were 3.9 percent for goats (n = 410) and 4.3 percent for sheep (n = 400). The prevalences of seropositive animals were low in the mesoregion of Sertão Pernambucano (4.8 percent for goats and 4.1 percent for sheep) and São Francisco Pernambucano (1.0 percent for goats and 4.5 percent for sheep). There were no significant differences between species and regions. Considering the social and economic importance of goats and sheep raising in the semi-arid region, it is essential to establish preventive measures to control imports of ruminants from these areas.

Influence of a 60 Hz, 3 µT, electromagnetic field on the somatic maturation of wistar rat offspring fed a regional basic diet during pregnancy / Influência do campo eletromagnético de 60 Hz, 3 µT, na maturação somática de filhotes de ratos wistar alimentados pela dieta básica regional durante a prenhez

The aim of the present study was to observe how the exposition of pregnant rats to an electromagnetic field (EMF), with frequency of 60 Hz, and a magnetic field of 3 µT for 2 hours per day and/or using the so-called Regional Basic Diet (RBD), influenced the somatic maturation in their offspring. Four groups were formed: Group A (casein), B (casein and EMF), C (RBD) and D (RBD and EMF). The diet manipulation occurred during pregnancy. The somatic maturation indexes - assessed daily between 12:00 AM and 2:00 PM - were: Eye Opening (EO), Auricle Opening (AO), Auditory Canal Opening (ACO), Low Incisor Eruption (LIE), and Upper Incisor Eruption (UIE). The association between EMF and deficient diet caused a delay in all Somatic Maturation Indexes (SMI) and the RBD caused delay only in the AO. Furthermore, the EMF caused delay in AO, ACO, LIE. In relation to the body weight, the EMF associated with the deficient diet caused change in the twenty-first day of life. The RBD, during pregnancy, caused lower body weight in the offspring in the first and third day of life. The body weight of the offspring whose mothers were fed casein and exposed to the EMF during pregnancy was lower in the third and sixth day of life. In conclusion, the EMF associated with under-nutrition caused delay in all SMI. In relation to the body weight, the EMF associated with under-nutrition caused a decrease in the body weight at the sixth day of life.

O objetivo deste estudo foi observar a influência do campo eletromagnético (CEM), com freqüência de 60Hz, campo magnético de 3 µT, durante 2 horas por dia, associado ou não à dieta básica regional (DBR) no desenvolvimento somático da prole. Quatro grupos foram formados: Grupo A (caseína), B (caseína e CEM), C (DBR) e D (DBR e CEM). A manipulação dietética ocorreu durante a prenhez. Os índices de maturação somática - Abertura dos Olhos (AO), Abertura do Pavilhão Auditivo (APA), Abertura do Conduto Auditivo (ACA), Erupção do Incisivo Inferior (EII), e Erupção do Incisivo Superior (EIS) - foram avaliados diariamente entre 12 e 14 horas. A associação entre o CEM e a dieta deficiente causou retardo em todos os índices de maturação somática (IMS) e a DBR causou retardo somente na APA. O CEM causou retardo na APA, ACA, EII. Em relação ao peso corporal, o CEM associado à dieta deficiente causou mudanças no 21º dia de vida. A DBR, durante a prenhez, causou diminuição do peso corporal dos filhotes no 1º e no 3º dia de vida. O peso corporal dos filhotes, cujas mães foram alimentadas pela caseína e expostas ao CEM, durante a prenhez, apresentaram uma diminuição no 3º e 6º dia de vida. Conclusão: o CEM, associado com a desnutrição, causou retardo em todos os IMS. Em relação ao peso corporal, o CEM, associado à desnutrição, causou uma diminuição no peso corporal no 6º dia de vida.

Efeitos de três programas de fisioterapia respiratória (PFR) em portadores de DPOC / Effects of three respiratory physical therapy programs on patients with COPD

OBJETIVO: Avaliar os efeitos de três programas de fisioterapia respiratória constituídos por treinamento físico (TF) em esteira e/ou treinamento muscular respiratório (TMR) em pacientes com DPOC. MÉTODOS: Participaram deste estudo 25 pacientes com DPOC moderada-grave, de ambos os sexos, que foram divididos aleatoriamente em 3 grupos, sendo o primeiro grupo (G1) submetido a TMR com 30 por cento da pressão inspiratória máxima obtida a cada semana, o segundo grupo (G2) submetido a TF com 70 por cento da freqüência cardíaca atingida no teste de exercício cardiorrespiratório (TECR) sintoma-limitado e o terceiro grupo (G3) associava TMR ao TF com as mesmas intensidades citadas anteriormente. Todos os programas constituíram-se de 3 sessões semanais por 6 semanas consecutivas. RESULTADOS: Após tratamento, foram observados aumentos significativos da força muscular respiratória (FMR) no G1; aumentos significativos da distância percorrida no TECR, redução da freqüência cardíaca e do volume minuto expirado isovelocidade e melhora do domínio da capacidade funcional do questionário de qualidade de vida no G2; aumento significativo da FMR, da distância percorrida no TECR, redução da pressão arterial sistólica e concentração sangüínea de lactato isovelocidade e melhora da qualidade de vida no G3. CONCLUSÃO: Os resultados sugerem que o TF associado ao TMR foi a melhor alternativa terapêutica dentre as investigadas no presente estudo; pois, além de proporcionar uma evidente melhora na tolerância ao esforço e na qualidade de vida dos pacientes, promoveu um efeito adicional nas adaptações fisiológicas ao exercício, com uma maior eficácia na remoção e/ou menor produção de lactato sangüíneo durante o esforço.

OBJECTIVE: To evaluate the effects of three respiratory physical therapy programs consisting of physical training on a treadmill and/or respiratory muscle training (RMT), on patients with COPD. METHODS: Twenty-five patients of both sexes with moderate-to-severe COPD were randomized into three groups: the first group (G1) underwent RMT at 30 percent of the maximal inspiratory pressure obtained each week; the second group (G2) underwent physical training at 70 percent of the heart rate achieved in the symptom-limited cardiorespiratory exercise test (CRET); and the third group (G3) underwent RMT together with physical training, at the same intensities mentioned above. All of the programs consisted of three sessions per week for six consecutive weeks. RESULTS: Following treatment, significantly increased respiratory muscle strength was observed in G1. In G2, there was significantly increased walking distance and decreased heart rate and expiratory minute ventilation in CRET at the same velocity (isovelocity), and improvement in the functional capacity domain of the quality of life (QOL) questionnaire. In G3, there was significantly increased respiratory muscle strength, increased walking distance, decreased systolic arterial pressure and decreased blood lactate in CRET at the same velocity, and improvement in QOL. CONCLUSION: These findings suggest that physical training together with RMT was the best therapeutic alternative among the programs investigated in the present study. As well as providing an evident improvement in effort tolerance and QOL in the patients, it provided an additional effect regarding physiological adaptations to exercise with greater efficacy in clearance and/or lower production of blood lactate during effort.

Is avoidant disorder part of the social phobia spectrum in a referred sample of Brazilian children and adolescents?

The diagnosis of avoidant disorder was deleted from the Diagnostic and Statistical Manual of Mental disorders - fourth edition (DSM-IV) based on a `committee decision' suggesting that avoidant disorder is part of the social phobia spectrum. The objective of the present study was to examine the nature of this clinical association in a referred sample of Brazilian children and adolescents. We assessed a referred sample of 375 youths using semi-structured diagnostic interview methodology. Demographic (age at admission to the study and sex) and clinical (level of impairment, age at onset of symptoms and pattern of comorbidity) data were assessed in subsamples of children with avoidant disorder (N = 7), social phobia (N = 26), and comorbidity between both disorders (N = 24). Although a significant difference in the male/female ratio was detected among groups (P = 0.03), none of the other clinical variables differed significantly among subjects that presented each condition separately or in combination. Most of the children with avoidant disorder fulfilled criteria for social phobia. Thus, our findings support the validity of the conceptualization of avoidant disorder as part of the social phobia spectrum in a clinical sample.
