ABSTRACT
Background: many doubts about the infection of SARS-CoV-2 were raised, such as sexual transmission, sterility, and changes in fertility procedures; however, information is not clearly stated and organized. Purpose: to review and summarize scientific evidence on detection of SARS-CoV-2 in semen samples of Covid-19 patients. Methods:literature search in PubMed, Web of Science, Scopus, Medline and Embase databases, and followed Scoping Review protocol defined by Joanna Briggs Institute (JBI) after the guiding question "Is it possible to detect SARS-CoV-2 in the semen of adult patients with a confirmed diagnosis of Covid-19?" Results: 287 studies were identified, and, after discerning analysis, 9 studies published in the English language were selected. Three researchers analyzed the studies for SARS-CoV-2 presence in the seminal fluid, patients' severity, days since the onset of disease, diagnosis confirmation, semen collection method, viral analysis method, and sample numbers. Conclusions: it was not possible to find strong evidence to confirm the presence or absence of Covid-19 in the semen of adult patients. New studies on the subject should be better designed, taking into account the possible anatomical and functional conditions and changes of the male reproductive system during and after the infection by SARS-CoV-2 (AU)
Objetivo: Revisar e resumir as evidências científicas em pesquisas realizadas para detectar a presença de SARS-CoV-2 em amostras de sêmen de pacientes com COVID-19. Métodos: A pesquisa de literatura foi conduzida nas bases de dados PubMed, Web of Science, Scopus, Medline e Embase. Seguiu o protocolo de revisão de escopo definido por Joanna Briggs Institute (JBI) e baseou-se na pergunta norteadora "É possível detectar SARS-CoV-2 no sêmen de pacientes adultos com diagnóstico confirmado de Covid-19?". Resultados: 287 estudos foram identificados, 9 estudos publicados em língua inglesa foram selecionados após análise minuciosa. Três pesquisadores analisaram os estudos em busca de presença de SARS-CoV-2 no fluído seminal, gravidade do paciente, dias desde o início da doença, confirmação diagnóstica, método de coleta de sêmen, método de análise viral e número de amostras. Conclusões: Não foi possível identificar fortes evidências para confirmar a presença ou ausência de COVID-19 no sêmen de pacientes adultos. Novos estudos sobre o tema devem ser melhor projetados, levando-se em conta as possíveis condições anatômicas e funcionais e mudanças no sistema reprodutor masculino durante e após a infecção por SARS-CoV-2 (AU)

PURPOSE: To evaluate the influence of combined clinical therapy and nutritional guidance on the recurrence of urolithiasis. METHODS: From our registry of patients with recurrent urolithiasis we selected 57 who had at least 5-years of follow-up. We collected 24h urine samples in order to analyze Ca, Na, uric acid, citrate, oxalate, and Mg concentrations and to assess urine volume. Patients filled out a clinical questionnaire before treatment, and abdominal radiographs and/or ultrasound were performed both before treatment and during the follow-up period. During follow-up, specific and individualized dietary advice was given based on the individual's metabolic disorders. Patients also received specific pharmacological treatment for their metabolic alterations. Outcome measures were metabolites in urine and the urolith recurrence rate. Pre- and post- intervention values were compared using tests as appropriate. RESULTS: Fifty six of the patients were male and the majority of patients were overweight. The mean BMI was 27 kg/m2. Urinary excretion of calcium, uric acid and sodium decreased significantly over the five year follow-up period. The number of uroliths that formed during the 5-year follow-up also decreased significantly compared to pre-treatment values. CONCLUSION: Individualized dietary advice combined with pharmacological treatment significantly reduces long-term urolithiasis recurrence. .
