HELLP syndrome and COVID-19: A minor revision of a possible new "COVID-19-linked HELLP-like syndrome".

To report the characteristics described in the literature on a possible new "COVID-19-linked HELLP-like syndrome" in pregnant women with COVID-19: its association with the severity; prevalence; clinical; laboratory; pathophysiological and therapeutic management differences from the classic HELLP syndrome and their impact on outcomes. Observational, cohort, case-control, case-series and case-report studies were included. Data were extracted independently by the authors of the study, to ensure accuracy, consistency and performed the quality assessment. The database search resulted in 77 references, of which two satisfied the eligibility criteria. In these 2 studies we found a possible "COVID-19-linked HELLP-like syndrome", associated with severe COVID-19. There is a high possibility of the existence of "COVID-19-linked HELLP-like syndrome" and its association with severe COVID-19 in pregnant women, with a prevalence of 28,6%. Some characteristics of "COVID-19-linked HELLP-like syndrome" and the classic HELLP syndrome are similar. Differential diagnosis indicated two different types of therapeutic management: conservative for "COVID-19-linked HELLP-like syndrome" and delivery for the HELLP syndrome. HELLP clinical management is mandatory for both.

COCONUT OIL EFFECT IN THE COMPLICATIONS OF HEPACTIC DISEASE / EFEITO DO ÓLEO DE COCO NAS COMPLICAÇÕES DA DOENÇA HEPÁTICA

Background: Prevention of the progression of cirrhosis with dietary supplementation has been in focus Coconut oil has been suggested. Objective: To evaluate the effect of coconut oil supplementation in cirrhotic rats. Method: Forty Wistars were divided: control (CO), control + coconut oil (CO + OC), thioacetamide (TAA) and thioacetamide + coconut oil (TAA + OC). TAA was added to water for 13 weeks and coconut oil was administered by gavage. Blood, liver, muscle and nervous tissue samples were obtained for laboratory and histopathological analyses. Results: AST, ALT, total cholesterol, HDL, LDL, triglycerides were not statistically significant. In histology, even without differences, there was a tendency towards significance regarding the proliferation of bile ducts, fibrotic septa and muscle fiber atrophy between the TAA and TAA + OC groups. Conclusion: No significant protective effect of coconut oil on liver disease was found.

Racional: A prevenção da evolução da cirrose com suplementação dietética tem estado em foco óleo de coco tem sido sugerido. Objetivo: Avaliar o efeito da suplementação de óleo de coco em ratos cirróticos. Método: Quarenta Wistar foram divididos: controle (CO); controle + óleo de coco (CO+OC); tioacetamida (TAA) e tioacetamida + óleo de coco (TAA + OC). O TAA foi adicionado à água por 13 semanas e o óleo de coco administrado por gavagem. Amostras de sangue, fígado, tecido muscular e nervoso foram obtidas para análises laboratorial e histopatológica. Resultados: AST, ALT, colesterol total, HDL, LDL, triglicérides não foram estatisticamente significantes. Na histologia, mesmo sem diferenças, houve tendência na significância quanto a proliferação de ductos biliares, septos fibróticos e atrofia da fibra muscular entre os grupos TAA e TAA + OC. Conclusão: Não foi encontrado efeito protetor significativo do óleo de coco na doença hepática.

The Effect of Stool Transplantation on Weight Control in Obese Rats / O efeito do transplante de fezes no controle de peso em ratos obesos

Abstract Introduction Obesity is defined as a multifactorial metabolic syndrome in which there is an excessive number of fat cells within the tissues. It is discussed that intestinal microbiota might have a relevant relation with obesity, since it is relevantly altered in obese patients. Objectives To assess the effect of stool transplantation (ST) in the condition of obesity and its outcomes in an experimental model of cafeteria diet by analyzing histology and weight gain. Methods Forty male Wistar rats were randomly assigned to 5 groups: control (CO), control with antibiotics (CO+ATB), obesity (CAF+ATB), stool transplantation (ATB+ ST) and obesity with stool transplantation (CAF+ATB+ST). During the experiment, obesity induction groups received cafeteria diet, whereas the remaining groups had normal diet ad libitum. After 3 months, daily ST was carried out for 8 weeks by gavage procedure. The animals were euthanized, and the small intestine was harvested for further analysis. Results It was observed that before starting the ST, the cafeteria and normal diet groups had significant weight difference (p<0,0001). In the comparison between CAF+ATB and CAF+ATB+ST during the gavage period, the CAF+ATB+ST group presented lower weight gain (p=0.0017). The histopathological evaluation show that the ATB+ST group did not present intestinal crypt distortion. Conclusion Cafeteria diet resulted in an expected weight gain. In relation to the ST, it has been shown that the procedure is effective in reducing weekly weight gain. Apparently, there was no induction of disabsortive syndrome in nonobese animals that received ST.

Resumo Introdução A obesidade é definida como uma síndrome metabólica multifatorial, na qual existe um número excessivo de células de gordura nos tecidos. Discute-se que a microbiota intestinal pode estar relacionada com a obesidade, uma vez que ela é alterada de forma relevante em pacientes obesos. Objetivos Avaliar o efeito do transplante de fezes (TF) na obesidade induzida por um modelo experimental de dieta de cafeteria. Métodos Quarenta ratos Wistar foram distribuídos aleatoriamente em 5 grupos: controle (CO), controle com antibióticos (CO+ATB), obesidade (CAF+ATB), transplante de fezes (ATB+TF) e obesidade com transplante de fezes (CAF+ATB+TF). Durante o experimento, os grupos de indução de obesidade receberam dieta de cafeteria, enquanto os demais grupos tiveram dieta ad libitum normal. Após 3 meses, o TF diário foi realizado por 8 semanas por meio de gavagem intragástrica. Os animais foram sacrificados e o intestino delgado foi colhido para análise posterior. Resultados Observou-se que antes de iniciar o TF, os grupos de dieta de cafeteria e dieta normocalórica apresentavam diferença significativa de peso (p<0,0001). Ao comparar os grupos CAF+ATB e CAF+ATB+TF durante o período de gavagem, o grupo CAF+ATB+TF apresentou menor ganho de peso (p=0,0017). A avaliação histopatológica mostra que nenhum dos animais do grupo TF+ATB apresentou distorções nas criptas intestinais. Conclusão A dieta da cafeteria resultou em um ganho de peso esperado. Em relação ao TF, demonstrou-se que o procedimento é eficaz na redução do ganho de peso semanal. Aparentemente, não houve indução da síndrome disabsortiva em animais não obesos que receberam TF.

Profile of Laryngeal Microsurgeries in Patients Over 60 Years Old

Abstract Introduction The increase in life expectancy is an incentive to the development of researches with the elderly population aiming at actions that may ensure healthy and active aging. Objective To analyze the profile of laryngeal microsurgery performed in patients > 60 years old. Methods A retrospective observational study, with a cross-sectional design. A retrospective analysis of the medical records of elderly patients submitted to laryngeal microsurgery was performed at a private hospital in Curitiba, state of Paraná, Brazil, between January 2004 and December 2016. Were included all of the patients > 60 years old that underwent laryngeal microsurgery during this period. Results During the studied period, 213 laryngeal microsurgeries were performed in 181 patients > 60 years old. There was a preponderance of male patients. The mean age was 67.6 years old. Squamous cell carcinoma (SCC) was the most prevalent disorder (26%), followed by Reinke edema (20%), papillomatosis (14%), polyps (11%), leukoplakia (8%), minor structural alterations (8%), associated lesions (9%), and others (4%). Men presented a higher probability of SCC diagnosis, regardless of the age group, while Reinke edema was more frequently observed in women. A directly proportional relation between the frequency of laryngeal cancer and age increase was also observed. No significant differences were observed in professional voice users. Conclusion Further researches are required to properly comprehend the factors associ- ated with laryngeal lesions and determine prevention and treatment approaches.
