Moment of induction and duration of experimental varicocele in rats: effects on semen quality.

PURPOSE: Varicocele is a condition known to cause damage to seminal parameters and sperm function. Furthermore, it has been hypothesized that the varicocele effect on fertility is time-dependent; however, little is known about the consequences of its establishment time on reproductive organs and/or sperm function. This study aimed to evaluate the effect of the duration of experimental varicocele on reproductive organs, sperm parameters, and sperm function. MATERIALS AND METHODS: Varicocele induction surgeries were performed in Wistar rats aged 40 or 100 days old. At 160-day-old, analyses were performed, including biometry of reproductive organs (prostate, seminal vesicles, epididymis, and testis), sperm parameters (vitality, morphology, and motility), and sperm function tests (nuclear DNA integrity, acrosome integrity, and mitochondrial activity). RESULTS: The analysis of the biometry of reproductive organs showed no differences between distinct ages in which varicocele was induced. The total abnormal sperm morphology was bigger in animals with varicocele induced to 100 days old than in animals with varicocele induced to 40 days old. Regarding nuclear DNA integrity, animals of varicocele induced to 100 days old showed worse results compared to animals of varicocele induced to 40 days old. Other parameters analyzed showed no differences between varicocele groups. CONCLUSION: In this study conducted on rats, we conclude that varicocele adversely affects sperm, particularly its function. However, we did not observe a negative progressive effect on sperm.

[Temporal trend in the prevalence of malnutrition in children under five assisted by the Brazilian Income Transfer Program (2008-2019)]. / Tendência temporal da prevalência de desnutrição em crianças menores de 5 anos assistidas pelo Programa Bolsa Família (2008-2019).

This study aimed to analyze the temporal trend of malnutrition in children aged under five years assisted by the Brazilian Income Transfer Program from 2008 to 2019, by exploring regional inequalities and seeking to determine the impact of the economic and political crises aggravated in 2014, and the government's adherence to fiscal austerity policies on the trend. The analyses were performed using aggregated data from infants (0-23 months) and preschoolers (24-59 months), extracted from the Brazilian Food and Nutritional Surveillance System (SISVAN) assisted by the Brazilian Income Transfer Program (n = 34,272,024). Trends were analyzed using generalized linear models with age-specific mixed effects (negative binomial distribution and log linkage function). The regional inequalities were analyzed based on the grouping of Federative Units according to the Social Vulnerability Index (SVI) and the influence of crises and austerity policies on the prevalence of malnutrition by the interaction between "year" and "crisis" (2008-2013 vs. 2014-2019). There was a reduction in the prevalence of child malnutrition until mid-2013, when the trends became stationary for preschoolers and upward for infants. There was also a higher risk of malnutrition in Federative Units with medium- and high-social vulnerability, when compared to those with low-social vulnerability. The inflection points in the trends corroborate the hypothesis that the political and economic crises, and the governmental responses to these crises, negatively impacted the nutritional status of children in poverty and extreme poverty in Brazil.

As desigualdades regionais foram analisadas a partir do agrupamento das Unidades Federativas segundo o Índice de Vulnerabilidade Social (IVS) e a influência das crises e das políticas de austeridade na prevalência de desnutrição por meio da interação entre "ano" e "crise" (2008-2013 vs. 2014-2019). Houve redução na prevalência de desnutrição infantil até meados de 2013, quando as tendências passaram a ser estacionárias para pré-escolares e ascendentes para lactentes. Observou-se, também, maior risco de desnutrição nos estados com média e alta vulnerabilidade social, quando comparadas àqueles com baixa vulnerabilidade social. Os pontos de inflexão nas tendências corroboram a hipótese de que as crises política e econômica, e as respostas governamentais a essas crises, provocaram impacto negativo sobre o estado nutricional de crianças em situação de pobreza e extrema pobreza no Brasil.

Excess Mortality in Kidney and Kidney-Pancreas Transplant Recipients in the COVID-19 Pandemic in Portugal-A Cohort Study.

The COVID-19 pandemic increased morbidity and mortality worldwide, particularly in the Kidney and Kidney-Pancreas Transplant Recipient (KTR/KPTR) population. Aiming at assessing the absolute and relative excess mortality (EM) in a Portuguese KTR/KPTR cohort, we conducted a retrospective observational study of two KTR/KPTRs cohorts: cohort 1 (P1; n = 2,179) between September/2012 and March/2020; cohort 2 (P2; n = 2067) between March/2020, and August/2022. A correlation between relative and absolute EM and age, sex, time from transplantation and cause of death was explored. A total of 145 and 84 deaths by all causes were observed in P1 and P2, respectively. The absolute EM in P2 versus P1 was 19.2 deaths (observed/expected mortality ratio 1.30, p = 0.006), and the relative EM was 1.47/1,000 person-months (95% CI 1.11-1.93, p = 0.006). Compared to the same period in the general population, the standardized mortality rate by age in P2 was 3.86 (95% CI 2.40-5.31), with a peak at 9.00 (95% CI 4.84-13.16) in P2C. The higher EM identified in this population was associated, mainly, with COVID-19 infection, with much higher values during the second seasonal COVID-19 peak when compared to the general population, despite generalized vaccination. These highlight the need for further preventive measures and improved therapies in these patients.

An Unexpected Catastrophe-Renal Artery Thrombosis in a Living Donor: A Case Report.

BACKGROUND: Renal artery thrombosis is a devastating complication if not detected early. Cardioembolic disease or surgical and technical complications are frequent causes of renal artery thrombosis. There are some reports of renal artery thrombosis in a renal allograft, but to our knowledge, this is the first case of renal artery thrombosis reported in a kidney donor.

Pregnancy After Kidney Donation: The Experience in a Cohort of Portuguese Living Donors.

BACKGROUND: Living kidney donation (LKD) is a preferred treatment option for end-stage chronic kidney disease, but it can also pose potential risks for the donor, including hypertension and end-stage renal disease. Many donors are women of reproductive age who may have concerns about the effects of donation on future pregnancies. The aim of this study was to determine fetal and maternal outcomes in a cohort of pregnancies after LKD and to compare them with pregnancies before LKD. METHODS: We conducted a retrospective analysis of living kidney donors of childbearing age (<46 years old) at the time of donation who got pregnant after LKD in our center between 1987 and 2020 (N = 13). Clinical data were collected, including demographic characteristics and maternal and fetal outcomes. RESULTS: We observed 16 pregnancies after LKD and 12 pregnancies before LKD in the same group of patients. The rate of gestational hypertension was 12.5% in pregnancies after LKD and 8.3% before LKD (P = .999). There were 13 successful pregnancies after LKD with a mean gestational age of 38.6 ± 1.7 weeks. There were no episodes of acute kidney injury or other complications. CONCLUSION: The present study suggests that LKD does not have a negative effect on maternal and fetal outcomes. However, caution should be taken due to the small sample size. We agree with the guidelines recommending close monitoring of post-donation pregnancies.

The Beauty and the Beast: Bariatric Surgery and a Case of Oxalate Nephropathy.

Oxalate nephropathy is a rare cause of kidney failure. Roux-en-Y gastric bypass surgery is a technique used for surgical treatment of obesity as well as for the treatment of gastric carcinoma. We report the case of a 46-year-old male who was admitted to the nephrology department due to kidney dysfunction eight months after bariatric surgery.

Understanding the impact of varicocele on sperm capacitation.

OBJECTIVE: To study the relationship between the seminal sample quality of men with varicocele and sperm capacitation. DESIGN: Cross-sectional observational study. SETTING: Academic hospital. PATIENT(S): Seventy-six men (19 control and 57 with varicocele) were analyzed. INTERVENTION(S): Semen samples were submitted to a discontinuous density gradient for sperm selection. Sperm capacitation was induced using a human tubal fluid medium supplemented with bovine serum albumin. MAIN OUTCOME MEASURE(S): After capacitation induction, the sperm were assessed by capacitation state, computer-assisted sperm motility, mitochondrial activity, membrane integrity, acrosome reaction, and intracellular oxidative stress. RESULT(S): The capacitation period increased sperm motility, showing an increase in the average path velocity and a decrease in the straightness compared with sperm before capacitation (paired analysis). After capacitation, the rate of capacitated sperm, motility, and mitochondrial activity showed differences between groups (control and varicocele). The varicocele group showed lower mitochondrial activity and capacitation than the control group. On the other hand, no significant differences were observed in the other variables evaluated. CONCLUSION(S): Varicocele men showed less viable sperm and mitochondrial activity than control men after capacitation sperm. The induction of capacitation altered motility by increasing path velocity and decreasing straightness in all of the studied groups, evidencing the occurrence of hyperactivation.

"It's not all about the disease": do treatment and socioeconomic status affect perceived impact and satisfaction of patients treated for cutaneous leishmaniasis?

BACKGROUND: This cross-sectional study compared the general impact of cutaneous leishmaniasis (CL) and patient satisfaction with treatment and health services as perceived by those undergoing different therapeutic regimens in an endemic region in South-Eastern Brazil. We also investigated the factors associated with both outcomes (general impact and satisfaction). METHODS: We included 84 patients with CL treated between 2018 and 2019 with intravenous meglumine antimoniate, liposomal amphotericin B, or intralesional meglumine antimoniate therapy. Data were collected through interviews that assessed sociodemographic characteristics, comorbidity status, access and use of health services for CL diagnosis and treatment, and the items of the Cutaneous Leishmaniasis Impact Questionnaire (CLIQ). The CLIQ is a psychometric questionnaire previously validated to assess the general impact of CL on patient satisfaction with treatment and health services. Multivariate logistic regression analysis was used to identify the factors associated with high CL impact and low patient satisfaction. RESULTS: The general impact of CL and patient satisfaction with treatment and health services were not significantly associated with the therapeutic regimen. High CL impact was associated with low family income (odds ratio [OR]:3.3; 95% confidence interval [CI]:1.0-10.3), occurrence of complications/adverse effects during treatment (OR:7.7; 95%CI:2.4-25.6), and additional costs during diagnosis and/or treatment (OR:12.1; 95% CI:2.8-52.4). Low satisfaction was associated with high disease impact (OR: 9.5; 95% CI:2.7-33.9), occurrence of complications/adverse effects (OR:4.2; 95% CI:1.3-13.0), and high family income (OR:7.1; 95%CI:1.7-28.2). CONCLUSIONS: Our data support public health policies aimed at reducing the impact of CL and its treatment as well as the use of therapy with fewer adverse effects.

Effect of chronic sleep deprivation on acrosomal integrity and functional parameters of murine sperm.

OBJECTIVE: To evaluate the effect of chronic sleep deprivation on sperm function quality in mice. DESIGN: Experimental study. SETTING: Not applicable. ANIMALS: Spermatozoa from twenty-four 10-week-old C57BL/6J male mice. INTERVENTION(S): The sleep deprivation group underwent gentle handling for 6 hours for 5 consecutive days. The mice in the sleep recovery group were allowed to sleep during the 24-hour period after the sleep deprivation protocol. MAIN OUTCOME MEASURE(S): After euthanasia, the spermatozoa were collected for analysis. Sperm motility was evaluated using computer-assisted sperm analyzer. Intracellular superoxide anion (O2-) activity, acrosome integrity, mitochondrial activity, and DNA fragmentation assays were conducted afterward. RESULT(S): Sleep deprivation and sleep recovery groups presented a lower percentage of spermatozoa with an intact acrosome, compared with the respective control groups. Regarding DNA fragmentation, a decreased proportion of spermatozoa with Comet I class intact DNA was observed in the sleep recovery group, compared with the recovery control group. Beat cross frequency was increased in the sleep recovery group. CONCLUSION(S): Sleep deprivation can reduce sperm quality, impairing acrosome integrity. Sleep recovery decreased DNA integrity and increased beat cross frequency.

Correr atrás do vento: o trabalho dos mototaxistas de Sobral, Ceará / Chasing the wind: the work of motorcycle taxi drivers from Sobral, Ceará / Perseguir el viento: el trabajo de los mototaxis de Sobral, Ceará

A pesquisa teve como objetivo geral analisar a atividade e o ofício dos mototaxistas de Sobral, Ceará. O objetivo específico foi compreender: a) a atividade exercida e o conceito de real da atividade; b) as prescrições; c) as regras informais; e d) as relações profissionais. A investigação adotou o referencial teórico da Clínica da Atividade, e participaram oito mototaxistas. Inspiradas no método da Instrução ao Sósia, foram realizadas e gravadas entrevistas semiestruturadas. Seu áudio foi transcrito e o conteúdo passou por análise construtivo-interpretativa. Os resultados mostraram que a atividade era regulamentada pela prefeitura e dependia da manutenção dos instrumentos utilizados. O expediente era organizado por uma regra do coletivo de trabalho relacionada ao horário de funcionamento de escolas e universidades. A busca por passageiros variava, sendo possível ficar em pontos fixos ou circular pela cidade. As condições ambientais demandavam cuidados como o uso de protetor solar e hidratação. A autonomia da profissão permitia organizar o próprio expediente e o ganho mensal. Entretanto, houve queixas relativas à falta de direitos previdenciários e ao fato de que a flexibilidade geraria uma sobrecarga de trabalho que poderia trazer prejuízos à saúde. Riscos foram identificados em acidentes de trânsito e violência urbana. Os relatos acerca das relações com os colegas mostraram um ambiente amistoso, e as relações com os passageiros eram definidas por cada situação, abrangendo desde interações objetivas até conversas pessoais.(AU)

The research had as general objective to analyze the activity and the work of motorcycle taxi drivers in Sobral, Ceará. Specific objectives were to understand: (a) the activity performed and the real of activity; (b) the prescriptions; (c) informal rules and (d) professional relationships. The investigation adopted the theoretical framework of the Clinic of Activity. Eight motorcycle taxi drivers participated in the investigation. Inspired by the instruction to the double method, semi-structured interviews were conducted. The audio of the interviews was transcribed and underwent constructive-interpretive analysis. The results showed that the activity was regulated by the city and depended on the maintenance of the instruments used. The working hours were organized by a collective labor rule related to the opening hours of schools and universities. The looking-for for passengers also varied: it was possible to stay at fixed points or move around the city. Environmental conditions required care such as the use of sunscreen and hydration. The profession's autonomy made it possible to organize its own hours and monthly earnings. However, there were complaints regarding the lack of social security rights and that flexibility would create an overload of work that could harm health. Risks have been identified in traffic accidents and urban violence. Reports about relationships with colleagues showed a friendly atmosphere. Relations with passengers were defined by each situation, ranging from objective interactions to personal conversations.(AU)

Time trend of the prevalence of malnutrition in children under five years of age assisted by the Bolsa Família Program (2008-2019) / Tendência temporal da prevalência de desnutrição em crianças menores de cinco anos assistidas pelo Programa Bolsa Família (2008-2019)

The objective of this study was to analyze the temporal trend of malnutrition in children under five years of age assisted by the Bolsa Família Program (PBF) between 2008 and 2019, exploring regional inequalities and seeking to determine the impact of the economic and political crises worsened in 2014 and of government adherence to fiscal austerity policies on the trend. Analyses were conducted using aggregate data from infants (0-23 months) and preschoolers (24-59 months) extracted from the Food and Nutrition Surveillance System (SISVAN) assisted by the PBF (n=34,272,024). Trends were analyzed using generalized linear models with age-specific mixed effects (negative binomial distribution and log-link function). Regional inequalities were analyzed by grouping the federative units according to the social vulnerability index (SVI) and the influence of crises and austerity policies on the prevalence of malnutrition by means of the interaction between "year" and "crisis" (2008-2013 vs. 2014-2019). There was a reduction in the prevalence of child malnutrition until mid-2013, when trends became stationary for preschoolers and upward for infants. Higher risk of malnutrition was also observed in states with medium and high social vulnerability compared to those with low social vulnerability. The turning point in the trends supports the hypothesis that the political and economic crises, and government responses to these crises, have negatively impacted the nutritional status of children in poverty and extreme poverty in Brazil.

Diagnostic approach in a patient with Creutzfeldt-Jakob disease / Abordagem diagnóstica em uma paciente com doença de Creutzfeldt-Jakob

ABSTRACT Prion diseases are an important cause of rapidly progressive dementias. Among them, the most common is sporadic Creutzfeldt-Jakob disease (CJD). It is a rare and incurable disease, with rapid progression to death. Objective: To describe the diagnostic approach of a patient with Creutzfeldt-Jakob disease. Methods: The diagnosis is established through the clinical picture associated with characteristic changes in the brain magnetic resonance imaging, the electroencephalogram, and analysis of specific changes in the cerebrospinal fluid. Results: The present report describes the case of a 53-year-old patient in the city of Fortaleza-CE. The diagnosis was made based on the clinical condition and through diagnostic tests, including 14-3-3 protein and RT QUIC analysis. Differential diagnosis was performed with other rapidly progressive causes, such as infectious and immune-mediated diseases. Conclusions: The diagnosis of probable sporadic CJD was established.

[Validity of an instrument for screening households at risk of food insecurity in different strata of the Brazilian population]. / Validade do instrumento para triagem de domicílios em risco de insegurança alimentar em diversos estratos da população brasileira.

The absence of risk screening tools for food insecurity compromises the ability to assess, monitor, and provide immediate assistance to those in hunger, especially during emergencies such as the COVID-19 crisis. Hence, this study sought to test the validity of an instrument for Screening Households at Risk of Food Insecurity (TRIA) in different strata of the Brazilian population TRIA uses questions 2 and 4 of the Brazilian Food Insecurity Scale (EBIA), originally validated using data from the Brazilian National Survey of Demography and Health of Children and Women (PNDS 2006). In this study, using data from the Brazilian National Household Sample Survey (PNAD 2013), its reproducibility was tested by repeating the original combinatorial procedures, examining whether the parameters of sensitivity, specificity, accuracy, and positive predictive values (PPV) and negative values (NPV) would result in the same arrangement of questions. Moreover, convergent validity was analyzed by comparing the strength of association between food insecurity and dietary variables using two binomial regression models (TRIA x EBIA). Results indicated that the combination of questions 2 and 4 performed best among the population strata studied, and presented optimal convergent validity. PPV and NPV adjusted for food insecurity prevalence in states ranged from 42.8% (Santa Catarina) to 87.6% (Amazonas) and 95.8% (Amazonas) to 99.5% (Santa Catarina), respectively. In conclusion, besides being reproducible, TRIA presented excellent validity parameters, especially among vulnerable groups. It can thus be used in care practice and as an instrument of food and nutritional surveillance in Brazil.

A ausência de instrumentos de triagem de risco para insegurança alimentar compromete a capacidade de avaliar, monitorar e ofertar assistência imediata a pessoas em situação de fome, especialmente durante emergências, como a crise da COVID-19. Assim, o objetivo deste estudo foi testar a validade do instrumento de Triagem para Risco de Insegurança Alimentar (TRIA), em diversos estratos da população brasileira. A TRIA é composta pelas questões 2 e 4 da Escala Brasileira de Insegurança Alimentar (EBIA), validada, originalmente, a partir de dados da Pesquisa Nacional de Demografia e Saúde da Criança e da Mulher (PNDS 2006). Neste estudo, utilizando dados da Pesquisa Nacional por Amostra de Domicílios (PNAD 2013), testou-se sua reprodutibilidade por meio da repetição dos procedimentos combinatórios originais, examinando se os parâmetros de sensibilidade, especificidade, acurácia e valores preditivos positivo (VPP) e negativo (VPN) resultariam no mesmo arranjo de questões. Ainda, analisou-se a validade convergente comparando a força de associação entre insegurança alimentar e variáveis alimentares por meio de dois modelos de regressão binomial (TRIA x EBIA). Os resultados indicaram que a combinação das questões 2 e 4 apresentou melhor desempenho entre os estratos populacionais estudados, além de ótima validade convergente. O VPP e VPN ajustado pela prevalência de insegurança alimentar nos estados variou de 42,8% (Santa Catarina) a 87,6% (Amazonas) e 95,8% (Amazonas) a 99,5% (Santa Catarina), respectivamente. Em conclusão, além de ser reprodutível, a TRIA apresentou excelentes parâmetros de validade, sobretudo em grupos vulnerabilizados. Assim, seu uso pode ser recomendado na prática assistencial e como instrumento de vigilância alimentar e nutricional no Brasil.

Interstitial nephritis secondary to treatment with pembrolizumab, a rare complication in two patients with lung adenocarcinoma.

Immune checkpoint inhibitors (ICPi) have become nowadays one of the most widely prescribed anticancer treatments. Pembrolizumab is a highly selective monoclonal immunoglobulin approved as a first-line monotherapy treatment in adult patients with untreated advanced non-small cell lung cancer (NSCLC) with programmed cell death 1 (PD-L1) expression greater than 50% and lack of mutations. ICPi can precipitate immune-related adverse events. Data on the incidence and characteristics of nephrotoxicity from ICPi are limited and caused largely from small case series and oncologic studies. Two patients with a diagnosis of pulmonary adenocarcinoma, undergoing treatment with pembrolizumab who manifested interstitial nephritis secondary to this treatment, are presented below. The growing use of immunotherapy in the treatment of cancer imposes the physician's attention to possible adverse effects.

Short communication: Feasibility of dengue vaccine to infect different human cell lines: An alternative potency test using HEK293T cells.

Dengue is caused by an arbovirus that belongs to the Flaviviridae family and there are four distinct, but close related, circulating serotypes. Dengue disease is of great importance for global public health, with vaccination being its main prophylactic measure. However, there is a paucity of biological models for evaluating tetravalent dengue vaccines. The aim of this study was to evaluate the susceptibility of human cell lines HEK293T and THP-1 to a commercial dengue vaccine and test the feasibility of this approach in the development of a potency assay with human cell lines, as a methodological alternative to the golden standard potency assay with VERO cells. In this context, we used a batch of the commercial vaccine Dengvaxia® (CYD-TDV) for the infection tests. We evaluated the presence of the vaccine virus in THP-1 cells, differentiated into macrophages (dTHP-1), and in HEK293T by confocal microscopy, using 4G2 pan-flavivirus antibody. Vaccine infectivity and potency were determined by immunocolorimetric assay using monoclonal antibodies specific for each serotype. The results indicated that the human strain HEK293T was responsive to the tetravalent vaccine, as shown by the presence of virus particles in the cell cytoplasm in a pattern similar to the one observed with VERO cells. Moreover, it was possible to determine the infectivity and potency values of each vaccine virus serotype in the HEK293T, with serotype 4 prevailing over the others. Thus, the human cell line HEK293T provides a potential candidate to be used in assays to determine potency and identity of tetravalent dengue vaccines.

Process mining for healthcare: Characteristics and challenges.

Process mining techniques can be used to analyse business processes using the data logged during their execution. These techniques are leveraged in a wide range of domains, including healthcare, where it focuses mainly on the analysis of diagnostic, treatment, and organisational processes. Despite the huge amount of data generated in hospitals by staff and machinery involved in healthcare processes, there is no evidence of a systematic uptake of process mining beyond targeted case studies in a research context. When developing and using process mining in healthcare, distinguishing characteristics of healthcare processes such as their variability and patient-centred focus require targeted attention. Against this background, the Process-Oriented Data Science in Healthcare Alliance has been established to propagate the research and application of techniques targeting the data-driven improvement of healthcare processes. This paper, an initiative of the alliance, presents the distinguishing characteristics of the healthcare domain that need to be considered to successfully use process mining, as well as open challenges that need to be addressed by the community in the future.

Diagnostic approach in a patient with Creutzfeldt-Jakob disease.

Prion diseases are an important cause of rapidly progressive dementias. Among them, the most common is sporadic Creutzfeldt-Jakob disease (CJD). It is a rare and incurable disease, with rapid progression to death. Objective: To describe the diagnostic approach of a patient with Creutzfeldt-Jakob disease. Methods: The diagnosis is established through the clinical picture associated with characteristic changes in the brain magnetic resonance imaging, the electroencephalogram, and analysis of specific changes in the cerebrospinal fluid. Results: The present report describes the case of a 53-year-old patient in the city of Fortaleza-CE. The diagnosis was made based on the clinical condition and through diagnostic tests, including 14-3-3 protein and RT QUIC analysis. Differential diagnosis was performed with other rapidly progressive causes, such as infectious and immune-mediated diseases. Conclusions: The diagnosis of probable sporadic CJD was established.

SARS-CoV-2 is not found in human semen during mild COVID-19 acute stage.

The aim of this study was to verify the presence of SARS-CoV-2 in the seminal sample of men during the acute phase of COVID-19. A prospective study was performed with inclusion of twenty-two men diagnosed with COVID-19 through RT-PCR from pharyngeal smear samples and who were in the acute phase of infection. These men were evaluated regarding medical history and physical examination. Furthermore, seminal samples of each men were collected 7, 14 and 21 days after the infection was confirmed. The sample were used for seminal analysis, as well as for the presence of SARS-CoV-2 using RT-PCR technique. In addition, cell culture was performed with subsequent repetition of the analysis of viral presence. None of the semen samples collected was positive for the detection of the virus that causes COVID-19. Most of the men evaluated had a mild condition and the loss of smell was the most frequent symptom. There were no significant changes in seminal parameters within the period of study. Based on our pilot data, patients with a mild form of COVID-19 in the acute stage of the disease are unlikely to have SARS-CoV-2 in semen.
