Cadmium toxicity symptoms and uptake mechanism in plants: a review / Sintomas de toxicidade de cádmio e mecanismo de absorção em plantas: uma revisão

Cadmium (Cd) is one of non-essential heavy metals which is released into environment naturally or anthropogenically. It is highly persistent toxic metals that are exceptionally distressing industrial and agriculture activities by contaminating soil, water and food. Its long-duration endurance in soil and water results in accumulation and uptake into plants, leading to the food chain. This becomes a serious global problem threatening humans and animals as food chain components. Living organisms, especially humans, are exposed to Cd through plants as one of the main vegetative food sources. This review paper is concentrated on the symptoms of the plants affected by Cd toxicity. The absorption of Cd triggers several seen and unseen symptoms by polluted plants such as stunted growth, chlorosis, necrosis and wilting. Apart from that, factors that affect the uptake and translocation of Cd in plants are elaborated to understand the mechanism that contributes to its accumulation. By insight of Cd accumulation, this review also discussed the phytoremediation techniques-phytoextraction, phytostimulation, phytostabilization, phytovolatization and rhizofiltration in bioremediating the Cd.

O cádmio (Cd) é um dos metais pesados ​​não essenciais que é liberado no meio ambiente de forma natural ou antropogênica. São metais tóxicos altamente persistentes que prejudicam excepcionalmente as atividades industriais e agrícolas, contaminando o solo, a água e os alimentos. Sua resistência de longa duração no solo e na água resulta em acúmulo e absorção pelas plantas, levando à cadeia alimentar. Isso se torna um sério problema global que ameaça humanos e animais como componentes da cadeia alimentar. Os organismos vivos, principalmente os humanos, são expostos ao Cd através das plantas como uma das principais fontes de alimento vegetativo. Este artigo de revisão concentra-se nos sintomas das plantas afetadas pela toxicidade do Cd. A absorção de Cd desencadeia vários sintomas visíveis e invisíveis por plantas poluídas, como crescimento atrofiado, clorose, necrose e murcha. Além disso, são elaborados fatores que afetam a absorção e translocação de Cd nas plantas para entender o mecanismo que contribui para o seu acúmulo. A partir do conhecimento do acúmulo de Cd, esta revisão também discutiu as técnicas de fitorremediação - fitoextração, fitoestimulação, fitoestabilização, fitovolatização e rizofiltração na biorremediação do Cd.

Molecular characterization and incidence of new tospovirus: Soybean Vein Necrosis Virus (SVNV) in Egypt

Abstract Field survey study was conducted season (2017). Soybeans and weeds were weekly sampled randomly. Thrips adults were identified and counted. Detection of the virus isolate and the natural incidence was determined using; Mechanical transmission, host range, DAS-ELISA, RT-PCR. The natural incidence thrips individuals was detected depending on the SVNV% in thrips individuals and weeds hosts. Ten thrips species were associated with soybean plants in the field. The most abundant species was T. tabaci, average 256.5 average no.of individuals, followed by F. occidentalis (142.5 average no. of individuals), then N. variabilis (86.6/ average no. of individuals). Fourteen thrips species occurred on 5 legumes field crops and 41 weed plant species within soybean field. The highest average number 40.6.of individuals were recorded on Ammi majus. While the lowest one 3.3 average no. of individuals were on Urtica urens. Only 21diagnostic plant species were susceptible to infection with SVNV. G. max and Vigna radiate, were the highest percentage of infection 80% followed by V. unguilata & N. benthamiana, 75%. Egyptian isolate of Soybean vein necrosis virus (SVNV) in this study showed a high degree of similarity and it is closely related to TSWV from Egypt (DQ479968) and TCSV from USA (KY820965) with nucleotide sequence identity of 78%. Four thrips species transmitted SVNV (F. fusca 4.0%, F. schultzei 4.3%, F. tritici 3.3% and N. variabilis 68.0% transmission). Both C. phaseoli and M. sjostedti can acquire the virus but unable to transmit it. The following species; T. tabaci, F. occidentalis, S. dorsallis and T. palmi cannot acquire or transmit SVNV. The incidence of SVNV in the field started by the end of July then increased gradualy from 12.7 to 71.3% by the end of the season. In conclusion, few thrips individuals invaded soybean crops are enough to transmit high rate of SVNV within the crop. Furthermore, several vector species are also abundant on weeds, which are the major sources of soybean viruses transmitted to the crops. This information might be important for control and reduce the incidence of SVNV infection.

Resumo O estudo de pesquisa de campo foi realizado na temporada (2017). A soja e as ervas daninhas foram amostradas semanalmente de forma aleatória. Tripes adultos foram identificados e contados. A detecção do vírus isolado e a incidência natural foram determinadas usando transmissão mecânica, gama de hospedeiros, DAS-ELISA, RT-PCR. A incidência natural de tripes em indivíduos foi detectada dependendo da % de SVNV em tripes e hospedeiros infestantes. Dez espécies de tripes foram associadas a plantas de soja no campo. A espécie mais abundante foi T. tabaci, com média de 256,5 número médio de indivíduos, seguida por F. occidentalis (142,5) e N. variabilis (86,6 / número médio de indivíduos). Catorze espécies de tripes ocorreram em 5 culturas de leguminosas e 41 espécies de plantas daninhas dentro de campos de soja. O maior número médio de 40,6 indivíduos foi registrado em Ammi majus. Enquanto o mais baixo, 3,3 número médio de indivíduos, foi no Urtica urens. Apenas 21 espécies de plantas diagnosticadas foram suscetíveis à infecção com SVNV. G. max e Vigna radiate foram os maiores percentuais de infecção, 80%, seguidos por V. unguilata e N. benthamiana, 75%. O isolado egípcio neste estudo mostrou um alto grau de similaridade e está intimamente relacionado ao TSWV do Egito (DQ479968) e ao TCSV dos EUA (KY820965), com identidade de sequência de nucleotídeos de 78%. Quatro espécies de tripes transmitiram SVNV (F. fusca 4,0%, F. schultzei 4,3%, F. tritici 3,3% e N. variabilis 68,0% de transmissão). Tanto C. phaseoli quanto M. sjostedti podem adquirir o vírus, mas não podem transmiti-lo. As seguintes espécies, T. tabaci, F. occidentalis, S. dorsallis e T. palmi não podem adquirir ou transmitir SVNV. A incidência de SVNV no campo, iniciada no final de julho, aumentou gradativamente de 12,7 para 71,3% no final da temporada. Em conclusão, poucos indivíduos de tripes invadiram a cultura da soja e são suficientes para transmitir alta taxa de SVNV dentro da cultura. Além disso, várias espécies de vetores também abundam em ervas daninhas, que são as principais fontes dos vírus da soja transmitidos às lavouras. Essas informações podem ser importantes para controlar e reduzir a incidência de infecção por SVNV.

Objetivo: avaliar a eficácia da Ivermectina e do Atazanavir em comparação com placebo no tempo de resolução dos sintomas e no tempo de duração da doença por COVID-19. Método: estudo observacional, de coorte prospectivo, longitudinal, descritivo e analítico com pacientes sintomáticos ambulatoriais, acompanhados por 06 meses em duas Unidades Básicas de Saúde para atendimento de COVID-19 em Teresina- Piauí, Brasil, no período de novembro a abril de 2021 identificados por amostragem aleatória 1:1:1. Foram realizados exames Reverse transcription polymerase chain reaction (RT-PCR) para confirmação laboratorial da suspeita de infecção pelo novo coronavírus e avaliação sociodemográfica e clínica. Resultados: dos 87 pacientes randomizados, 62,1% (n=54) eram do sexo masculino, com média de idade de 35,1 anos, possuíam companheira (53,9%), baixa renda (50,6%), eutróficos (40,7%) e sem comorbidades de saúde (78,2%). Não houve diferença entre o tempo médio para resolução dos sintomas, que foi de 21 dias (IQR, 8-30) no grupo atazanavir, 30 dias (IQR, 5-90) no grupo ivermectina em comparação com 14 dias (IQR, 9-21) no grupo controle. No dia 180, houve resolução dos sintomas em 100% no grupo placebo, 93,9% no grupo atazanavir e 95% no grupo ivermectina. A duração mediana da doença foi de 08 dias em todos os braços do estudo. Conclusão: o tratamento com atazanavir (6 dias) e ivermectina (3 dias) não reduziu o tempo de resolução dos sintomas e nem o tempo de duração da doença entre os pacientes ambulatoriais com COVID-19 leve em comparação com o grupo placebo. Os resultados não suportam o uso de ivermectina e atazanavir para tratamento de COVID-19 leve a moderado.

Objective: to evaluate the effectiveness of Ivermectin and Atazanavir compared to placebo in the time to resolution of symptoms and duration of illness due to COVID-19. Method: observational, prospective, longitudinal, descriptive and analytical cohort study with symptomatic outpatients, followed for 06 months in two Basic Health Units for COVID-19 care in Teresina-Piauí, Brazil, from November to April 2021 identified by 1:1:1 random sampling. Reverse transcription polymerase chain reaction (RT-PCR) tests were performed for laboratory confirmation of suspected infection with the new coronavirus and sociodemographic and clinical evaluation. Results: of the 87 randomized patients, 62.1% (n=54) were male, with a mean age of 35.1 years, had a partner (53.9%), low income (50.6%), eutrophic (40.7%) and without health comorbidities (78.2%). There was no difference between the median time to resolution of symptoms, which was 21 days (IQR, 8-30) in the atazanavir group, 30 days (IQR, 5- 90) in the ivermectin group compared with 14 days (IQR, 9- 21) in the control group. At day 180, there was resolution of symptoms in 100% in the placebo group, 93.9% in the atazanavir group, and 95% in the ivermectin group. The median duration of illness was 8 days in all study arms. Conclusion: Treatment with atazanavir (6 days) and ivermectin (3 days) did not reduce the time to symptom resolution or the duration of illness among outpatients with mild COVID-19 compared to the placebo group. The results do not support the use of ivermectin and atazanavir for the treatment of mild to moderate COVID-19.

Impacto de la cardiomiotomía laparoscópica de Heller en la función del esfínter esofágico inferior y el diámetro del esófago / Impact of laparoscopic Heller cardiomyotomy on lower esophageal sphincter function and esophageal diameter

Introducción. La acalasia es un trastorno motor del esófago caracterizado por la ausencia de peristalsis y la alteración en la relajación del esfínter esofágico inferior. La cardiomiotomía laparoscópica de Heller más funduplicatura parcial es el tratamiento estándar. La mejoría sintomática ha sido bien documentada, pero no hay suficiente información objetiva respecto a los cambios fisiológicos y radiográficos luego del procedimiento. Métodos. Estudio de cohorte bidireccional de pacientes llevados a cardiomiotomía laparoscópica de Heller, entre los años 2018 y 2021, en el Hospital Universitario San Vicente Fundación de Medellín, Colombia. Se describen variables demográficas y clínicas. Se realizaron puntaje sintomático de Eckardt, manometría esofágica y radiografía de esófago en el pre y postoperatorio. Se hizo comparación de síntomas, presión basal del esfínter esofágico inferior, presión de relajación integrada y diámetro del esófago antes y después de la intervención. Resultados. Se incluyeron 24 pacientes. El 63 % fueron mujeres y la edad promedio fue de 44 años. Los valores promedio preoperatorios vs postoperatorios fueron: puntaje de Eckardt 10,6 vs 1,4 puntos (p<0,001), presión basal de 41,4 vs 18,1 mmHg (p=0,004) y presión de relajación integrada de 28,6 vs 12,5 mmHg (p=0,001). El diámetro del esófago no presentó cambios. No hubo correlación de síntomas con los cambios de presión del esfínter esofágico inferior. El tiempo de seguimiento fue de 20 meses. Conclusiones. La cardiomiotomía de Heller es un procedimiento altamente efectivo para el tratamiento definitivo de la acalasia, logrando una mejoría subjetiva y objetiva basada en síntomas y en parámetros de manometría, respectivamente

Introduction. Achalasia is a motor disorder of the esophagus characterized by the absence of peristalsis and impaired relaxation of the lower esophageal sphincter. Laparoscopic Heller ́s cardiomyotomy plus partial fundoplication is the standard treatment. Symptomatic improvement has been well documented, but there is insufficient objective information regarding physiologic and radiographic changes after the procedure. Methods. Bidirectional cohort study of patients underwent laparoscopic Heller ́s cardiomyotomy between 2018 and 2021 at the San Vicente Fundación University Hospital in Medellín, Colombia. Demographic and clinical variables are described. Eckardt symptom score, esophageal manometry, and esophageal radiography were performed pre and postoperatively. A comparison of symptoms, baseline lower esophageal sphincter pressure, integrated relaxation pressure, and esophageal diameter before and after intervention were performed.Results. 24 patients were included. 63% were women and the average age was 44 years. The preoperative vs. postoperative mean values were: Eckardt score 10.6 vs. 1.4 points (p<0.001), basal pressure of 41.4 vs. 18.1 mmHg (p=0.004) and integrated relaxation pressure of 28.6 vs. 12.5 mmHg (p=0.001). The diameter of the esophagus did not present changes. There was no correlation of symptoms with lower esophageal sphincter pressure changes. The follow-up time was 20 months. Conclusions. Heller cardiomyotomy is a highly effective procedure for the definitive treatment of achalasia, achieving subjective and objective improvements, based on symptoms and manometry parameters, respectively

Social-emotional issues among children with strabismus higher than among non-strabismus children in Western India

Purpose: Data on social?emotional aspects among children with strabismus in India are scanty. We compared the emotional symptoms (ES), loneliness and social dissatisfaction (LSD), and self?esteem (SE) and their associated risk factors among children with and without strabismus in India. Methods: A cross?sectional case–control study design was used to recruit 101 children with strabismus aged 8 to 18 years and a control group of 101 children that were age? and gender?matched. Interviews were performed using standardized scales to assess ES, LSD, and SE. Variations in the intensity of ES, LSD, and SE were assessed using multiple classification analysis (MCA). Results: A total of 202 children participated in the study. The mean ES, LSD, and SE scores were 3.4 (standard deviation [SD] 1.9), 48.4 (SD 3.2), and 22.1 (SD 3.8) for the strabismus group and 1.8 (SD 1.5), 33.3 (SD 3), and 31.3 (SD 2) for the non?strabismus group, respectively. Among the strabismus group, the highest levels of mean ES, LSD, and SE scores were observed among children facing problems in performing daily tasks. Amongst the non?strabismus group, children studying at the primary level and those facing neglect had the highest mean scores. In MCA, being affected with strabismus had the highest effect on the intensity of ES, LSD, and SE with a beta (?) value of 0.223 (P = 0.016), 0.922 (P < 0.001), and 0.853 (P < 0.001). Conclusion: A significantly high proportion of children with strabismus deal with elevated levels of ES, LSD problems, and low SE as compared with non?strabismus children, highlighting the need to address the poor social?emotional health of children

Inter-relações entre insatisfação com o trabalho docente e sintomas depressivos: modelagem com equações estruturais / Interrelationships between dissatisfaction with teaching work and depressive symptoms: Structural equation modelling

Resumo O objetivo deste artigo é avaliar inter-relações de fatores associados a sintomas depressivos (SD) em professores, considerando a insatisfação com o trabalho docente como possível mediador. Estudo transversal utilizando dados de 700 professores da rede pública de ensino de um município brasileiro. O desfecho de interesse foi SD aferido pelo Inventário de Depressão de Beck (BDI). Foram testadas inter-relações diretas e indiretas entre o desfecho e insatisfação com o trabalho, idade, renda, estilo de vida e adiposidade. Essas variáveis compuseram modelo operacional testado por meio de modelagem de equações estruturais. A maior idade (β=0,12) e a maior insatisfação com o trabalho (β=0,12) associaram-se diretamente aos SD. Já o estilo de vida mais favorável (β=-0,60) e a adiposidade (β=-0,10), associaram-se a menor ocorrência de SD. As variáveis estilo de vida (β=-0,06) e adiposidade (β=-0,02) também apresentaram efeitos indiretos negativos nos SD, mediados pela insatisfação com o trabalho. O modelo de equação estrutural testado identificou inter-relações que influenciaram os SD. A insatisfação com o trabalho docente associou-se aos SD e mediou a relação de outros fatores sobre tais sintomas.

Abstract The objective of this article is to evaluate the interrelationships of factors associated with depressive symptoms (DS) in teachers, considering dissatisfaction with the teaching job as a possible mediator. This was a cross-sectional study using data from 700 teachers from the public school system of a Brazilian municipality. The outcome of interest was DS, as assessed using the Beck Depression Inventory (BDI). Direct and indirect interrelationships between the outcome and dissatisfaction with work, age, income, lifestyle and adiposity were tested. These variables composed the operational model tested by structural equation modelling. Older age (β=0.12) and greater dissatisfaction with work (β=0.12) were directly associated with DS. A more favourable lifestyle (β=-0.60) and adiposity (β=-0.10) were associated with a lower occurrence of DS. The variables lifestyle (β=-0.06) and adiposity (β=-0.02) also had negative indirect effects on DS, mediated by job dissatisfaction. The structural equation model tested identified interrelationships that influenced DS. Dissatisfaction with teaching work was associated with DS and mediated the relationship of other factors with such symptoms.

Associação entre ansiedade e depressão em brasileiros durante o isolamento social da pandemia de covid-19 / Association between anxiety and depression in brazilians during the social isolation of the COVID-19 pandemic / Asociación entre ansiedad y depresión en brasileños durante el aislamiento social por la pandemia del COVID-19

O objetivo deste estudo é analisar a associação entre ansiedade e depressão durante o isolamento social da pandemia de covid-19 no Brasil. Dados de 1.053 adultos brasileiros entre 18 e 59 anos foram coletados por meio de questionário online, entre abril e maio de 2020, para este estudo transversal. Foi utilizada a Escala Hospitalar de Ansiedade e Depressão, e foram analisados fatores sociodemográficos e econômicos. Houve 37% e 20% de risco moderado e alto de ansiedade, respectivamente. Foi observada uma relação direta entre ansiedade e ser do sexo feminino (OR: 1,55; IC95%: 1,02-2,34), ser mais jovem (OR: 4,78; IC95%: 2,71-8,42, para pessoas entre 18-28 anos) e ter rendimentos mais baixos (OR: 1,51; IC95%: 1,69-1,96). Os resultados foram na mesma direção para a depressão, e, adicionalmente, foi demonstrada associação entre isolamento social (parcial ou total) e depressão (OR: 1,42; IC95%: 1,01-2,01). Este estudo encontrou uma associação entre mulheres, populações mais jovens e indivíduos de menor renda e o risco de sofrer ansiedade e depressão durante o confinamento decretado devido à pandemia de covid-19. Além disso, o isolamento social foi associado ao risco de depressão.

The aim of this study is to analyze the association between anxiety and depression during the social isolation for COVID-19 in Brazil. Data of 1,053 Brazilian adults between 18 and 59 years old were gathered by an online questionnaire, between April and May 2020, for this cross-sectional study. The Hospital Anxiety and Depression Scale was used and sociodemographic and economic factors were analyzed. There was a 37% and 20% of moderate and high risk of anxiety, respectively. A direct relationship was observed between anxiety and being female (OR: 1.55; 95%CI: 1.02-2.34), younger (OR: 4.78; 95% CI: 2.71-8.42, for people between 18-28 years old), and having lower incomes (OR: 1.51, 95%CI: 1.69-1.96). Results were in the same vein for depression and, additionally, an association between social isolation (partial or total) and depression was shown (OR: 1.42; 95%CI: 1.01-2.01). This study reported an association between women, younger populations, and subjects with lower incomes and the risk of suffering anxiety and depression during the confinement due to the COVID-19 pandemic. In addition, social isolation was associated with risk of depression.

Se recolectaron datos de 1.053 adultos brasileños, de entre 18 y 59 años de edad, mediante un cuestionario en línea, entre abril y mayo de 2020, para este estudio transversal. Se utilizó la Escala de Ansiedad y Depresión Hospitalaria, y se analizaron factores sociodemográficos y económicos. Hubo el 37% de riesgo moderado de ansiedad y el 20% de riesgo alto. Se observó una relación directa entre la ansiedad y ser mujer (OR: 1,55; IC 95%: 1,02-2,34), ser más joven (OR: 4,78; IC 95%: 2,71-8,42 para personas de entre 18 y 28 años) y tener menores ingresos (OR: 1,51; IC 95%: 1,69-1,96). Los resultados fueron los mismos para la depresión y, además, se demostró una asociación entre el aislamiento social (parcial o total) y la depresión (OR: 1,42; IC 95%: 1,01-2,01). Este estudio encontró una asociación entre ser mujer, poblaciones más jóvenes y personas de bajos ingresos con el riesgo de experimentar ansiedad y depresión durante el confinamiento por la pandemia del COVID-19. Además, el aislamiento social se asoció con el riesgo de depresión.

Características clínico-epidemiológicas de pacientes post-COVID-19 en Baracoa, Guantánamo

Fundamento un elevado porcentaje de personas que han padecido COVID-19, refieren tras la recuperación de la fase aguda, manifestaciones que se prolongan por más de tres semanas, e incluso, durante tres meses después del cuadro clínico original. Objetivo caracterizar desde el punto clínico y epidemiológico a pacientes confirmados al SARS-CoV-2 en la etapa post-COVID-19. Métodos se realizó un estudio descriptivo transversal, en pacientes confirmados al SARS-CoV-2 en etapa post-COVID-19, pertenecientes al Policlínico Hermanos Martínez Tamayo, en el periodo octubre-noviembre de 2021. Se estudiaron todos los pacientes (N=400) atendidos en consulta post-COVID-19 en el periodo declarado. La información se obtuvo mediante encuestas epidemiológicas realizadas. Resultados predominaron los pacientes con edades entre 50 y 59 años, del sexo femenino. Las manifestaciones clínicas más frecuente fueron tos, pérdida del gusto y del olfato. El esquema de vacunación incompleto fue el más frecuente. El lugar de ingreso más utilizado fueron los centros de aislamiento, así como el uso del Nasalferon como tratamiento. Las complicaciones predominaron en pacientes no vacunados, y con edad de 60 años y más. Conclusiones un elevado porcentaje de pacientes presentó manifestaciones clínicas tras el periodo agudo de la enfermedad. La COVID-19, a mediano plazo, tuvo mayores implicaciones en el sistema respiratorio, nervioso y osteomioarticular. Las campañas de vacunación ayudan a prevenir los síntomas graves del virus y a contrarrestar las complicaciones.

Background a high percentage of people who have suffered from COVID-19 report, after recovery from the acute phase, manifestations that last for more than three weeks, and even for three months after the original clinical picture. Objective to characterize, from the clinical and epidemiological point of view, patients confirmed to SARS-CoV-2 in the post-COVID-19 stage. Methods a descriptive cross-sectional study was carried out in patients confirmed to SARS-CoV-2 in the post-COVID-19 stage, belonging to the Hermanos Martínez Tamayo Polyclinic, from October to November 2021. All patients were studied (N= 400) attended in post-COVID-19 consultation in the declared period. The information was obtained through epidemiological surveys carried out. Results there was a predominance of patients aged between 50 and 59 years old, female. The most frequent clinical manifestations were cough, loss of taste and smell. The incomplete vaccination scheme was the most frequent. The most used place of admission were isolation centers, as well as the use of Nasalferon as a treatment. Complications predominated in unvaccinated patients, and aged 60 years and over. Conclusions a high percentage of patients presented clinical manifestations after the acute period of the disease. COVID-19, in the medium term, had greater implications in the respiratory, nervous and osteomyoarticular systems. Vaccination campaigns help prevent serious symptoms of the virus and counteract complications.

Follow-up of infants with congenital syphilis during the penicillin shortage period

Abstract Objective To analyze the follow-up, in specialized outpatient clinics, of infants reported with congenital syphilis during the penicillin shortage. Method A cross-sectional study was carried out in ten public maternity hospitals affiliated with the Brazilian Unified Health System in the city of Fortaleza, state of Ceará. Clinical records of infants reported with congenital syphilis who were born alive in 2015 were used to describe correlates of attendance at recommended clinical follow-up appointments. Results A total of 469 infants reported with CS from January 1/2015 to December 31/2015 were included in the analysis. The results show that most infants did not attend the follow-up visits (368/469, 78.5%) and the main associated factors are that the follow-up clinic is located in a different hospital from that where the infant was born (OR: 3.7; CI: 2.20-6.22; p< 0.001) and the use of illicit drugs by the mother (OR: 3.2; CI: 1.57-6.87; p= 0.002). Only 33.7% (34/101) were followed until discharge. Conclusion The majority of infants with reported congenital syphilis during this period did not attend the follow-up visits. Public health efforts aimed at reaching the parents of infants with CS should be a priority to ensure appropriate clinical identification and management of the associated outcomes of this vertically transmitted infection.

Sintomas vocais, ansiedade e depressão pré e pós-tireoidectomia / Vocal symptoms, anxiety and depression pre and post thyroidectomy / Síntomas vocales, ansiedad y depresión pre y post tiroidectomía

Introdução: Alterações na tireoide e a tireoidectomia podem levar à sintomatologia vocal e emocional.Objetivo: Correlacionar sintomas vocais e traços de ansiedade e depressão pré e pós-tireoidectomia. Métodos: Estudo observacional, longitudinal. Participaram 20 pacientes submetidos à tireoidectomia, ao exame visual laríngeo e à Escala de Sintomas Vocais (ESV) e Escala Hospitalar de Ansiedade e Depressão (HADS) no pré-operatório, pós 1 semana e pós 3 meses, com média de idade de 54,5 anos, maior prevalência do sexo feminino (85%) e tireoidectomia parcial (70%). Resultados: Os pacientes autorreferiram sintomas vocais em todos os momentos, com maior frequência após uma semana e diferença significativa entre o domínio físico pré e pós 1 semana. Na HADS, observou-se maior escore total no pré-operatório e diferença significante nos três momentos, em todos os domínios, com maior diferença entre pré e pós 1 semana. Houve correlação positiva fraca entre os domínios limitação, emocional e escore total da ESV com a subescala de ansiedade pós 1 semana, entre o escore total da ESV e o escore total da HADS e correlação positiva moderada entre os domínios limitação e emocional da ESV com o escore total da HADS após uma semana. Conclusão: Pacientes submetidos à tireoidectomia autopercebem sintomas vocais e traços de grau leve de ansiedade tanto no pré quanto pós 1 semana e após 3 meses de cirurgia com pior autorreferência após uma semana. Quanto maior a autorreferência de sintomas vocais, mais traços de ansiedade o paciente pode apresentar. (AU)

Introduction: Thyroid alterations and thyroidectomy can lead to vocal and emotional symptoms.Purpose: To correlate vocal symptoms and anxiety and depression traits pre and post-thyroidectomy. Methods: Observational, longitudinal study. Participants were 20 patients who underwent thyroidectomy, laryngeal visual examination and the Voice Symptom Scale (VoiSS) and Hospital Anxiety and Depression Scale (HADS) preoperatively, 1 week and 3 months after, with a mean age of 54.5 years, higher prevalence of female gender (85%) and partial thyroidectomy (70%). Results: The patients self-reported vocal symptoms at all times, more frequently after one week and a significant difference between the physical domain pre and post 1 week. In HADS, there was a higher total score in the preoperative period and a significant difference in the three moments, in all domains, with a greater difference between pre and post 1 week. There was a weak positive correlation between the limitation, emotional and total score of the ESV domains with the anxiety subscale after 1 week, between the total score of the ESV and the total score of the HADS, and a moderate positive correlation between the limitation and emotional domains of the ESV with the HADS total score after one week. Conclusion: Patients undergoing thyroidectomy self-perceived vocal symptoms and mild anxiety traits both before and after 1 week and after 3 months of surgery with worse self-report after one week. The greater the self-report of vocal symptoms, the more traces of anxiety the patient may present. (AU)

Introducción: Cambios en la tiroides y tiroidectomía pueden provocar síntomas vocales y emocionales. Objetivo: Correlacionar síntomas vocales y rasgos de ansiedad y depresión antes y después de tiroidectomía. Metodos: Estudio observacional/longitudinal. Participaron 20 pacientes que se les realizó tiroidectomía, examen visual laríngeo, Escala de Síntomas Vocales (ESV) y Escala Hospitalaria de Ansiedad y Depresión (HADS) en preoperatorio, 1 semana y 3 meses después, con edad media de 54,5 años, prevalencia del género femenino (85%) y tiroidectomía parcial (70%).

Conclusión: Los pacientes sometidos a tiroidectomía autopercibieron síntomas vocales y rasgos de ansiedad leve tanto antes como después de 1 semana y después de 3 meses de la cirugía con peor autoinforme después de una semana. Cuanto mayor es el autoinforme de síntomas vocales, más rastros de ansiedad puede presentar el paciente. (AU)

Suporte Familiar, Traço/Estado Depressivo e Motivos para Viver em Usuários da Atenção Primária/Secundária / Family Support, Depressive Traits/Conditions and Reasons For Living in Primary/Secondary Care Users / Lo Apoyo Familiar, Rasgos/Condiciones Depresivos y Razones Para Vivir en Usuarios de la Atención Primaria/Secundaria

A depressão pode ser desenvolvida, agravada e/ou prevenida em função de alguns fatores como suporte familiar e motivos para viver, além da possibilidade de ser concebida como traço e estado depressivo. O objetivo principal desta pesquisa foi testar um modelo teórico preditivo (path analysis) do suporte familiar sobre traço/estado depressivo e sobre os motivos para viver, em uma amostra de 123 participantes, composta por dois grupos: pacientes do CAPS-AD e da ESF e, posteriormente, verificar as diferenças desses aspectos na amostra estudada. Foram aplicados uma ficha sociodemográfica, a Escala Baptista de Depressão - Adulto (EBADEP-A), Inventário de Percepção de Suporte Familiar (IPSF), Escala de Traço e Estado Depressivo (ETED) e Escala Brasileira de Motivos para Viver (BEMVIVER). O resultado da path analysis indicou que os motivos para viver são explicados pelo estado e traço depressivo e pelo suporte familiar. Os pacientes do CAPS-AD, tinham maiores níveis de sintomatologia depressiva e estado depressivo do que o grupo do ESF. Pacientes do ESF apresentaram médias maiores de suporte familiar e motivos para viver. Conclui-se que investir em estratégias que potencializem os motivos para viver e o suporte familiar podem reduzir os riscos de sintomatologia depressiva.

Depression can be developed, worsened and/or prevented depending on some factors such as: family support and reasons for living, in addition to the possibility of being conceived with a depressive trait and state. The main objective of this research was to test a predictive theoretical model (path analysis) of family support on the depressive trait/state and reasons for living, in a sample of 123 participants, composed of two groups: patients from the Psychosocial Care Center- Alcohol and Drugs (CAPS-AD) and the Family Health Strategy (ESF) and verify the differences of these aspects in the studied sample. A sociodemographic form, the Baptista Depression Scale -Adult (EBADEP-A), the Perceived Family Support Inventory (IPSF), Trait and Depressive State Scale (DTS) and the Brazilian Scale of Reasons to Live (BEMVIVER) were applied. The result of the path analysis indicated that the reasons for living are explained by the depressive state and trait and family support. CAPS-AD patients had higher levels of depressive symptoms and depressive state than the ESF group. ESF patients presented higher means of family support and reasons to live. It is concluded that investing in strategies that enhance the reasons to live and family support can reduce the risks of depressive symptoms.

La Depresión puede desarrollarse, agravarse y prevenirse dependiendo de factores como: apoyo familiar y razones para vivir, además puede de ser concebido con un rasgo y estado depresivo. El objetivo de esta investigación fue probar un modelo teórico predictivo del apoyo familiar sobre el rasgo/estado depresivo y las razones de vivir y verificar las diferencias de esos aspectos en la muestra estudiada, de 123 participantes compuesta por dos grupos: pacientes del Centro de Atención Psicosocial - Alcohol y Drogas (CAPS-AD) y la Estrategia de Salud de la Familia (ESF). Se aplicó un formulario sociodemográfico, Escala de Depresión de Baptista - Adulto (EBADEP-A), Inventario de Apoyo Familiar Percibido (IPSF), Escala de Rasgo y Estado Depresivo (DTS), Escala Brasileña de Razones para Vivir (BEMVIVER). El resultado del análisis indicó que las razones para vivir a ser explicadas por el estado y rasgo depresivo y por el apoyo familiar. Los pacientes CAPS-AD tenían niveles más altos de síntomas y estado depresivo que el grupo ESF. Los pacientes ESF presentaron mayores medios de apoyo familiar y razones para vivir. Se concluye que invertir en estrategias que potencien estas razones y apoyo familiar puede en la reducción de los riesgos de síntomas depresivos.

Menstrual Abnormalities Among Adolescent Females Attending a Tertiary Care Hospital in North India

Background: To study the menstrual abnormalities among adolescent females attending a gynaecolocial outpatient department (OPD) in a tertiary care hospital. Material & Methods: It was a cross sectional study which was carried at outpatient department (OPD) of obstetrics and gynaecology, Government medical college Srinagar over a period of 6 months.

Clinical Profile and Quality of Life of Incident Hemodialysis Patients

Hemodialysis is the most commonly used treatment modality for end stage renal disease. A 6 months observational study was conducted in the Dialysis unit of Kasturba Hospital, Manipal to study the clinical profile, quality of life with the help of KDQoL SF 36 questionnaire and factors affecting quality of life of hemodialysis patients. A total of 45 participants were included who initiated dialysis in the year 2018 and 2019 and were receiving dialysis in our hospital. Out of 45 participant 77.8% were males and 22.2% were females, the mean age was 55.29 (11.29) years. 23 patient-initiated dialysis in the year 2018 22 patients-initiated dialysis in the year 2019. The prevalence of hypertension, diabetes mellitus and cardiovascular diseases in this population were found to be 95.2%, 35.6% and 8.9% respectively. The mean scores of the sub scales were analyzed with the help of scoring manual and descriptive statistics. In the result it was found the hemoglobin, intradialytic weight gain were found to be positively correlated with the Physical component summary (PCS) and Mental component summary (MCS). Effects of kidney disease was found to be very strongly and positively correlated with dialysis vintage. In the result of the study due to its smaller population we cannot determine more factors which were affecting the Quality of life scores.

El impacto del TDAH sobre la lectura / The impact of ADHD on reading

Resumen Más allá de la frecuente coexistencia del trastorno por déficit de atención con hiperactividad (TDAH) y el trastorno específico del aprendizaje de la lectura, la presente revisión pretende examinar la evidencia empírica disponible sobre cómo el TDAH impacta negativamente sobre el aprendizaje de la lectura. Los datos existentes apuntan a que la presencia del trastorno (especialmente los síntomas de falta de atención), puede afectar a i) la correcta adquisición de lectura, ya sea de manera directa o a través de su influencia sobre los precursores de la lectura; ii) las propias habilidades de decodificación (precisión y fluidez lectora), tanto de manera directa como indirecta a través de su influencia sobre procesos cognitivos como la distracción o las funciones ejecutivas; y ii) la comprensión lectora, probablemente de manera indirecta por las dificultades eje cutivas y en la memoria de trabajo verbal características del TDAH. Estas conclusiones presentan importantes implicaciones para caracterizar e intervenir mejor sobre las dificultades lectoras en el TDAH, ya sean clínicas o subclínicas.

Abstract Beyond the frequent coexistence of attention deficit hyperactivity disorder (ADHD) and reading dis order (dyslexia), the present review aims to examine the available empirical evidence on how ADHD negatively impacts on learning to read. Existing data suggest that the presence of the disorder (especially inattention symp toms), may affect i) the correct acquisition of reading, either directly or through its influence on the precursors to reading; ii) decoding skills themselves (reading accuracy and fluency), both directly and indirectly through its influence on cognitive processes such as distractibility or executive functions; and iii) reading comprehension, probably indirectly through the executive and verbal memory difficulties characteristic of ADHD. These findings have important implications for better characterizing and intervening on reading difficulties in ADHD, whether clinical or subclinical.

Heart rate variability in patients presenting with anginal symptoms in absence of cardiac and other diseases

Objectives: Angina is a symptom of coronary artery disease (CAD). Modulation of cardiac autonomic tone as assessed by heart rate (HR) variability (HRV) is found reduced in patients with CAD; myocardial ischemia, myocardial infarction and some other cardiovascular diseases. Reduced HRV has been found associated with sudden cardiac death in these CAD patients. Several patients present with anginal symptoms clinically in absence of CAD or other diseases. The status of HRV is not much clear in these patients. Thus, we aimed to assess HRV in patients with angina with and without myocardial ischemia and compare it with HRV of healthy subjects of similar age groups and follow-up patients for 1 year for cardiac/health events. Materials and Methods: The study included 61 consecutive male patients clinically presenting with angina and 30 healthy subjects. Based on Thallium-201 myocardial perfusion Single-photon emission computerized tomography (SPECT) imaging, patients were divided into two groups; patients with myocardial perfusion defects (MPD), (n = 33, age 54.91 ± 7.43 years) and patients with no MPD (NMPD), NMPD (n = 28, age 53.04 ± 8.50 years). Short-term HRV was assessed in all patients and subjects in resting supine position following standard protocol. All MPD and 25 NMPD patients could be followed up for 1 year for cardiac/health events. Results: Surprisingly, the NMPD patients showed significantly reduced HRV, Standard deviation of the N-N intervals, The square root of the mean squared differences of successive N-N intervals, Percentage of the number of interval differences of successive N-N intervals greater than >50 ms divided by total number of R-R intervals, low frequency (LF) power, High Frequency (HF) power and total power as compared to both MPD patients and healthy subjects. (Total power [NMPD vs. MPD]: 610.1 [379.9–1072.8] vs. 1508.0 [748.4–2339.4] millisecond squares (ms2 ), P = 0.001), healthy subjects (Total power: 1414.6 [1104.6-2141.5] ms2 , P = 0.001). The markers of sympathetic tone; LF (normalised unit) and LF/HF ratio were higher in NMPD patients as compared to MPD patients resulting in an altered sympathovagal balance. During a 1-year follow-up, sudden death was seen in one MPD patient (3.1%) and two NMPD patients (8%). Conclusion: The NMPD patients showed significantly reduced HRV as compared to both MPD patients and Healthy subjects with an altered sympathovagal balance. Sudden death was also seen in NMPD patients as MPD patients.

Clinico-etiological Characteristics of Cystic Lung Disease: A Retrospective Study

Introduction: Diffuse cystic lung diseases (CLDs) are a heterogeneous group of uncommon disorders with characteristic imaging appearance. Cystic lung disease is a significant cause of mortality and morbidity with a wide spectrum of radiological presentations and etiological differentials. Though the literature is widely available on radiological approaches to CLD, a knowledge gap exists on the etiological spectrum, especially in the Indian scenario, as it is an orphan group of lung disorders. The interest and experience among pulmonologists regarding CLD are growing with the widespread use of CT scans. Clinical, radiographic, and histological findings are often essential for proper diagnosis, and multidisciplinary approach is required for optimal management of such cases. In our study, through real-world cases, we have highlighted the clinical manifestations and diverse etiological spectrum of CLD. Since these disorders are rare, incurable, and have variable disease progression, the authors have tried to address the holistic approach of this relatively less-understood group of disorders. Aims and objectives: The aim of the study was to identify clinical characteristics and etiological spectrum of patients manifesting with diffuse cystic lung disease radiologically. Materials and methods: In this retrospective analysis, the hospital electronic database was screened with Boolean operations and keywords for cysts OR pneumothorax. Among a total of 4,479 patients admitted to the respiratory ward /ICU during the period of January 2020–September 2022 at a tertiary care center in northern India, 14 patients with radiological diagnosis of CLD matched the relevant search. All relevant data of these patients were retrieved from the records. Results: Our patients presented predominantly with symptoms of cough and breathlessness. About 4 patients had pneumothorax as the first presentation. The mean age of presentation was 42.14 (standard deviation 12.6, age range 16–62 years). About 64% (n = 9/15) patients were females. The various etiologies identified were lymphangioleiomyomatosis (LAM), lymphocytic interstitial pneumonia, Birt–Hogg–Dube syndrome, hypersensitivity pneumonitis, Pneumocystis jirovecii pneumonia, and cystic metastasis, and in one patient, no definite cause was found despite detailed evaluation. Conclusion: Cystic lung disorders are a less commonly diagnosed entity with rare etiologies. In our study, we found a female preponderance and LAM as the commonest CLD. Pneumothorax is a sentinel event and commonly the presenting complaint in CLD. Identification of the etiology can help in institution of definite therapy when available. In view of unpredictable disease progression and outcome, these diseases warrant follow-up and imaging surveillance.

Infecção materna por SARS-CoV-2: descrição das notificações em gestantes / Maternal infection by SARS-CoV-2: description of notifications in pregnant women

Objetivo: Caracterizar as notificações de infecção por SARS-CoV-2 em gestantes em um município do sul de Santa Catarina. Métodos: Estudo transversal que avaliou as notificações de casos suspeitos de infecção por SARS-CoV-2 em gestantes no município de Tubarão, Santa Catarina, de março de 2020 a outubro de 2021. Coletaram-se os dados das fichas de notificação de infecção por SARS-CoV-2 da Fundação Municipal de Saúde e no Prontuário Eletrônico do Cidadão (PEC) das gestantes notificadas. A comparação da prevalência de confirmação segundo sintomas apresentados e características maternas foi realizada pela razão de prevalência (RP), com intervalo de confiança (IC) de 95%. Resultados: Foram registradas 555 notificações de gestantes suspeitas para a COVID-19, correspondentes a 487 mulheres. A prevalência de confirmação para a doença foi de 27,3%. O sintoma mais frequente no momento da notificação foi cefaleia (53,0%), entretanto o mais associado à confirmação foi a anosmia (RP: 2,28; IC 95%: 1,68-3,09). Das notificações registradas, 35,0% foram realizadas por gestantes que tiveram contato com casos suspeitos ou confirmados de COVID-19. O contato prévio foi mais relatado por gestantes assintomáticas, em comparação às gestantes que apresentaram sintomas (RP: 1,46; IC 95%: 1,12-1,91). Mulheres que relataram contato prévio com suspeitos ou confirmados para a COVID-19 apresentaram maior frequência de doença confirmada, quando comparadas às gestantes não expostas (RP: 1,80; IC 95%: 1,35-2,39). Conclusão: As gestantes, por terem maior susceptibilidade a surtos de doenças e gravidade do quadro, podem ter adotado com mais atenção medidas como a realização de testes diagnósticos quando em contato prévio com casos de COVID-19, mesmo assintomáticas.

Objective: To characterize the notifications of SARS-CoV-2 infection in pregnant women in a city in the South of Santa Catarina. Methods: Cross-sectional study that evaluated notifications of suspected cases of SARS-CoV-2 infection in pregnant women in the municipality of Tubarão, Santa Catarina, from March 2020 to October 2021. Data were collected from the SARS-CoV-2 infection notification forms from the Municipal Health Foundation, and from the Citizen's Electronic Health Record of the notified pregnant women. The comparison of the prevalence of confirmation according to symptoms and maternal characteristics was performed using the Prevalence Ratio (PR), with a confidence interval (CI) of 95%. Results: 555 notifications of suspected pregnant women for COVID-19 were registered, corresponding to 487 women. The prevalence of confirmation for the disease was 27.3%. The most frequent symptom at the time of notification was headache (53.0%), however, the most associated with confirmation was anosmia (PR: 2.28; 95% CI: 1.68-3.09). Of the notifications registered, 35.0% were made by pregnant women who had contact with suspected or confirmed cases of COVID-19. The previous contact was more frequently reported by asymptomatic pregnant women compared to pregnant women who had symptoms (PR: 1.46; 95% CI: 1.12-1.91). Women who reported previous contact with suspected or confirmed COVID-19 had a higher frequency of confirmed disease when compared to unexposed pregnant women (PR: 1.80; 95% CI: 1.35-2.39). Conclusion: Pregnant women, due to their greater susceptibility to disease outbreaks and disease severity, may have adopted more attentive measures such as diagnostic testing in the face of previous contact with cases of COVID-19, even if asymptomatic.
