HPV 18 variants in women with cervical cancer in Northeast Brazil.

BACKGROUND: Human Papillomavirus (HPV) is the main etiological factor for the development of cervical cancer. HPV 18 is the second most frequent type, accounting for up to 65% of all cases. HPV intratypic variation may influence the potential for progression to invasive cancer. The aim of this study was to evaluate the prevalence of human papillomavirus 18 intratypic variants in cervical cancer samples from women in the state of Maranhão, Brazil. METHODS: The study included 118 women over 18 years of age with a diagnosis of cervical cancer. Tumor fragments were collected and subjected to DNA extraction and Polymerase Chain Reaction (PCR) for HPV detection using the PGMY09/11 and GP+5/6 primers. Positive samples were submitted to automated sequencing for viral genotyping. To determine the HPV 18 lineages, positive samples were submitted to PCR, using specific primers to amplify the LCR and E6 regions of HPV 18 virus. RESULTS: HPV was present in 88 women (73.3%). Of those, 48 (54%) were HPV 16, the most prevalent, followed by 12 (13.6%) HPV 18. Histologically, squamous cell carcinoma was predominant (79.1%). Among the HPV 18 variants identified, 10 (80%) belonged to lineage A, and sublineages A1, A2, A3, and A4. Two (29%) HPV 18 B variant was also detected, with the sublineages B1 and B2. In this study, the C variant was not found. There was no statistically significant association between the HPV 18 lineages found and sociodemographic and lifestyle variables (p > 0.05). CONCLUSIONS: A higher frequency of HPV 16 and 18 were found in women with cervical cancer in the state of Maranhão, Brazil, with a high prevalence of the lineage A among women with HPV 18.

Assessment of trends, variability and impacts of droughts across Brazil over the period 1980-2019.

Drought indices are a numerical representation of drought conditions aimed to provide quantitative assessments of the magnitude, spatial extent, timing, and duration of drought events. Since the adverse effects of droughts vary according to the characteristics of the event, the socioeconomic vulnerabilities, exposed communities or environments, there is a profusion of drought indicators to assess drought impacts in different sectors. In this study, we evaluated the performance of two drought indices, the Standardized Precipitation Index-SPI and Standardized Precipitation Evapotranspiration Index-SPEI over Brazil derived from gridded meteorological information over the period 1980-2019. Firstly, we compared the gridded derived indices against the same indices derived from weather station data and available from a global dataset for time scales of 3, 6, 12, 24 months. Then we analyzed the spatio-temporal trends in SPI and SPEI time-series, which revealed statistically significant trends toward drier conditions across central Brazil for all time scales, though with more intensity for time scales of 12 months and larger. Trends were more significant in magnitude for SPEI than SPI, indicating an important role in the increase in evaporation, driven by increasingly higher temperatures. Finally, we demonstrated that climate signals are already having a disruptive effect on the country's energy security.

Investigation of antioxidant activity of ethanolic extract of the bark of Caesalpinia ferrea in Swiss mice exposed to paracetamol / Investigação da atividade antioxidante do extrato etanólico da casca de Caesalpinia ferrea em camundongos Swiss expostos ao paracetamol

Aims: it was evaluated the antioxidant effect of the ethanolic extract of Caesal-pinia ferrea bark in a model of oxidative stress induced by paracetamol (PCM). Methods: male Swiss mice were subdivided into four groups (control; PCM; PCM+extract; extract; n=8) in which a dose of paracetamol (250 mg.kg-1) was administered and after 3 hours the treatment with the extract (100 mg.kg-1/day) was administered for seven days, via gavage. Oxidative stress biomarkers were determined, such as catalase, glutathione-S-transferase, reduced gluta-thione, ascorbic acid, thiobarbituric acid reactive substances and carbonylated proteins of liver, kidneys and brain and plasma parameters through the dosage of glucose, cholesterol, triglycerides, aspartate aminotransferase and alanine aminotransferase. Results: the Caesalpinia ferrea extract was able to reverse the lipid and protein damage caused by the drug in the liver tissue and caused the same effect in the renal and brain tissues in the carbonylated proteins. The extract alone decreased liver glutathione-S-transferase and increased catalase and brain glutathione-S-transferase activity, in addition to lowering glucose and cholesterol, but without altering the triglycerides. Conclusions: it was possible to conclude that the ethanolic extract of the bark of Caesalpinia ferrea has a good antioxidant activity, probably due to dose of paracetamol in the samples investigated. However, more studies are needed for a better understanding of the effects of this extract compared to the effects found in this research

Objetivos: foi avaliado o efeito antioxidante do extrato etanólico da casca de Caesalpinia ferrea em modelo de estresse oxidativo induzido por paracetamol (acetaminofeno, PCM). Métodos: camundongos Swiss machos foram subdivididos em quatro grupos (controle; PCM; PCM+extrato; extrato; n=8) nos quais foi administrada uma dose de paracetamol (250 mg.kg-1) e após três horas foi administrado o tratamento com o extrato (100 mg.kg-1/ dia) por sete dias, via gavagem. Foram determinados biomarcadores de estresse oxidativo, como catalase, glutationa-S-transferase, glutationa reduzida, ácido ascórbico, substâncias reativas ao ácido tiobarbitúrico e proteínas carboniladas do fígado, rins e cérebro, além de parâmetros plasmáticos através da dosagem de glicose, colesterol, triglicerídeos, aspartato aminotransferase e alanina aminotransferase. Resultados: o extrato de Caesalpinia ferrea foi capaz de reverter os danos lipídicos e proteicos causados pela droga no tecido hepático, e também causou o mesmo efeito nos tecidos renal e cerebral nas proteínas carboniladas. O extrato sozinho diminuiu a atividade da glutationa-S-transferase hepática e aumentou a da catalase e glutationa-S-transferase cerebral, além de diminuir a glicose e o colesterol, mas sem alterar os triglicerídeos. Conclusões: foi possível concluir que o extrato etanólico da casca de Caesalpinia ferrea apresenta uma boa atividade antioxidante, provavelmente devido à presença de taninos, tendo em vista os danos causados pela alta dose de paracetamol nas amostras investigadas. Entretanto, mais estudos são necessários para um melhor entendimento dos efeitos deste extrato frente aos efeitos encontrados nesta pesquisa

In vivo mutagenic effects and oxidative stress parameters evaluation of cypermethrin and benzoate of emamectin and their mixtures in female mice.

We evaluated the biological effects of ingestion by gavage, for 28 days, of the pesticides cypermethrin (CP) and emamectin benzoate (EB) and their mixtures in female Swiss mice. The groups were Control (water); CP; EB and three distinct concentrations of CP and EB mixture expressed in mg/kg/day. The biological effects were analyzed in the complete blood count and plasma (alkaline phosphatase (ALP), alanine aminotransferase (ALT) and creatinine); the biochemical parameters of oxidative stress (substances reactive to thiobarbituric acid (TBARS); reduced glutathione (GSH); catalase (CAT), superoxide dismutase (SOD) and glutathione-S-transferase (GST)), and bone marrow cells obtained from the femur for the micronucleus (MN) test. In the heart, there was a reduction in GSH in the groups (0.5 + 0.67 and 2.5 + 3.37), although in the brain this effect appeared for the other groups, except EB. Brain TBARS increased in CP and in the group (2.5 + 3.37) and platelets increased in the group (12.5 + 16.87). Genotoxic/mutagenic effects, showing a consistent increase dose-dependent effect on micronucleus counting for in the female mice. After 28 days of treatment, we can observe that the pesticide mixtures promoted genotoxic damage and oxidative brain damage in female mice, which can damage the health of these animals and possibly their future offspring.

Increased climate pressure on the agricultural frontier in the Eastern Amazonia-Cerrado transition zone.

Several large-scale drivers of both anthropogenic and natural environmental changes are interacting nonlinearly in the transition zone between eastern Amazonia and the adjacent Cerrado, considered to be another Brazilian agricultural frontier. Land-use change for agrobusiness expansion together with climate change in the transition zone between eastern Amazonia and the adjacent Cerrado may have induced a worsening of severe drought conditions over the last decade. Here we show that the largest warming and drying trends over tropical South America during the last four decades are observed to be precisely in the eastern Amazonia-Cerrado transition region, where they induce delayed wet-season and worsen severe drought conditions over the last decade. Our results evidence an increase in temperature, vapor pressure deficit, subsidence, dry-day frequency, and a decrease in precipitation, humidity, and evaporation, plus a delay in the onset of the wet season, inducing a higher risk of fire during the dry-to-wet transition season. These findings provide observational evidence of the increasing climatic pressure in this area, which is sensitive for global food security, and the need to reconcile agricultural expansion and protection of natural tropical biomes.

Recurrent respiratory papillomatosis: clinical characteristics and viral genotyping in a Brazilian population.

This study presents 25 cases of recurrent respiratory papillomatosis (RRP) that occurred in Sao Luis, Maranhao State, Northeast region, Brazil, between January 2007 and December 2018. Sociodemographic and clinical profile of patients as well as human papillomavirus (HPV) infection status were evaluated. Clinical and histopathological data were collected from the patients' medical records. For the HPV infection analysis, DNA was extracted and subjected to amplification by a nested polymerase chain reaction. Viral genotyping was performed by automated sequencing. The median age of patients was 12.40 ± 12.6. years, and the juvenile form of the disease (68%) was the predominant form of disease. Female participants were predominant (60%), and they were from cities located in the interior of the State (60%). The most common clinical manifestation was dysphonia; recurrence was observed in most cases (56%), and tracheostomy was necessary in seven patients (26.9%). When comparing the RRP forms, patients in the juvenile-RRP group had higher recurrence rates and need of tracheostomy than those in the adult-RRP group. The viral genotyping analysis revealed that 47.8% of patients had low-risk HPVs, whereas 13.1% had high-risk HPVs, and in 39.1% of patients the viral genotype was not obtained. HPV-6 was the most prevalent type and Juvenile-RRP was more prevalent in our population. HPV was present at a high rate, and HPV-6 was the predominant genotype. This study serves as the basis for further studies to be conducted in the Brazilian population. Our findings aid the better understanding of RRP, possibly suggesting some prognostic factors associated with the disease aggressiveness.

Sentinel lymph node biopsy using single-agent mapping tracer (blue dye) after neoadjuvant chemotherapy in a Brazilian cohort of breast cancer patients. Real world evidence.

PURPOSE: To reduce false-negative rates (FNR) in sentinel lymph node biopsy (SLNB) of clinically positive (cN+) axilla in patients undergoing neoadjuvant chemotherapy (NAC). The removal of three or more lymph nodes with dual-tracer mapping including a radioisotope was used. However, in the Brazilian Unified Health System, the radioisotope tracer is not feasible in some hospitals. We conducted a cross-sectional study to evaluate the detection rate of sentinel lymph node (SLN) in patients who converted from cN+ to ycN0 after NAC using blue dye as a single-agent mapping tracer. METHODS: During the period of March 2018 to September 2019, 34 patients who underwent NAC with cN+ who converted to ycN0 were enrolled in the study. The SLNB was performed using blue dye as a single-agent mapping followed by axillary lymph node dissection (ALND). RESULTS: The detection rate of sentinel lymph node was of 85.3%, being SLNB not possible for five patients (14.7%), due to fibrosis. The mean number of removed SLN was 2.5. CONCLUSIONS: The use of blue dye as a single-agent mapping tracer demonstrated an acceptable detection rate of 85.3%. Although the FNR was possible to be determined, the small sample size might overestimate this rate. The removal of three or more lymph nodes with single-agent mapping tracer might be indicated for breast cancer patients who converted to ycN0 after NAC in the Brazilian health public services, in which radioisotope tracer is not suitable.

Trichomonas vaginalis as a risk factor for human papillomavirus: a study with women undergoing cervical cancer screening in a northeast region of Brazil.

BACKGROUND: Human papillomavirus (HPV) and Trichomonas vaginalis (TV) infections are the most common sexually transmitted infections (STIs) globally. The latter has contributed to a variety of adverse outcomes for both sexes. Moreover, in Brazil, epidemiological studies on patients with STIs are limited. Therefore, this study aimed to determine the prevalence of TV and its association with HPV in women undergoing cervical cancer screening. METHODS: Women with a normal cervix were recruited from a community-based cervical cancer screening program. Gynecological examinations were conducted, and questionnaires were provided. Vaginal canal and uterine cervix samples were collected for cytological examinations (reported using the 2001 Bethesda System) and tested for the presence of TV and HPV DNA. RESULTS: In total, 562 women who attended public primary healthcare were included in the study. The T. vaginalis was present in 19.0% (107) and HPV DNA was present in 46.8% (263) of women. Among the women of TV 73.8% (79) had a co-infection with HPV (p = 0.001). CONCLUSIONS: We concluded that a TV infection is associated with an HPV infection of the cervix as well as with the cervical cytological abnormalities. Further studies could reveal the mechanisms by which these two organisms interact at the cellular level, with control for shared behavioral risk factors.

Physiotherapy in nursing homes. A qualitative study of physiotherapists' views and experiences.

BACKGROUND: There are distinct differences in the implementation of physiotherapeutic care in nursing homes. Both nationally and internationally staffing levels of physiotherapy differ significantly between and within nursing homes. Since legislation or guidelines that specify the parameters of physiotherapy required in nursing homes are lacking, it is unknown how physiotherapists currently estimate the usefulness and necessity of physiotherapy in individual situations in long-term care. The purpose of this study was to describe how physiotherapists actually work, and how they want to work, in daily practice in Dutch nursing homes. METHODS: We performed a qualitative study with an online questionnaire. We asked 72 physiotherapists working in Dutch nursing homes to describe as accurately as possible usual care in nine different cases in long-term care. Furthermore we asked them to describe their role in the prevention and treatment of a number of indicators that measure the quality of care in nursing homes. Two reviewers thematically analysed the answers to the questionnaires. RESULTS: Forty-six physiotherapists returned the questionnaire. Physiotherapy services include active exercise therapy aimed to improve mobility and movement dysfunctions, advising on prevention and management of falls, pressure ulcers, incontinence, malnutrition and sarcopenia, overweight, physical restraints, intertrigo, chronic wounds, behavioural and psychological symptoms in dementia, and physical inactivity, and ergonomic and behavioural training. The way and extent in which physiotherapists are involved in the various care- and functional problems differs and depends on organisational and personal factors such as, organisation's policy, type of ward, time pressure, staffing level, collaboration with other members of the multidisciplinary team, or lack of knowledge. CONCLUSION: Physiotherapists in nursing homes are involved in the prevention and management of different care situations and functional problems. The way in which they are involved differs between physiotherapist. Aiming for more uniformity seems necessary. A shared vision can help physiotherapists to work more consistently and will strengthen their position in nursing homes.

Investigation of the possible protective effect of Smilax fluminensis steud. leaf in mice subjected to oxidative stress by paracetamol

Paracetamol (PCM) is a drug widely used by the population as an antipyretic and analgesic. If administered in high doses it can cause liver damage, leading to hepatoxicity. The genus Smilax, found in temperate and tropical regions, is traditionally used by the population through the extract of leaves and roots for several conditions, such as in the treatment of syphilis, diabetes, asthma and as a diuretic action. Through this, Smilax fluminensis leaf extracts were used to evaluate the protective effect against oxidative stress induced by a high dose of PCM in mice that received the drug and after receiving treatment with crude extract and fractions. Plasma analysis was performed using as partate aminotransferase (AST), alanine aminotransferase (ALT), glucose, triglycerides and cholesterol, in addition to biochemical techniques such as catalase (CAT), glutathione-S-transferase (GST), reduced glutathione (GSH), ascorbic acid (ASA), substances reactive to thiobarbituric acid (TBARS) and carbonylated proteins (CARBONYL) of liver, brain and kidneys. Fraction 1 of the extract was the most promising, decreasing the plasma levels of AST and ALT, the levels of CAT and GST of the liver, together with GSH and in the renal and brain tissue there was a decrease in carbonylated proteins (PCM + F1 versus PCM ). Besides, fraction 1 proved to be hypoglycemic and hypocholesterolemic. It is concluded that fraction 1 of Smilax fluminensis leaves has good antioxidant activity in the face of the damage caused by the high dose of paracetamol.

Asymptomatic COVID-19 in hospital visitors: The underestimated potential of viral shedding.

In a single day, six of 150 (4%) asymptomatic visitors were diagnosed with COVID-19 at a hospital with a universal masking policy. Two inpatients (contacts) subsequently developed symptoms. More rigorous protective measures during visitation periods may need to be included in infection control practices to reduce nosocomial transmissions.
