ABSTRACT

To date, there have been no new drugs or adjuvants able to decrease both morbidity and mortality in the context of sepsis and septic shock. Our objective was to evaluate the use of thiosulfinate-enriched Allium sativum and black garlic extracts as adjuvants in the management of sepsis. An experimental in vivo study was carried out with male Sprague-Dawley® rats. Animals were randomized in four treatment groups: antibiotic (ceftriaxone) treatment (group I), ceftriaxone plus thiosulfinate-enriched extract (TASE, group II), ceftriaxone plus thiosulfinate-enriched extract and black garlic extracts (TASE + BGE, group III), and ceftriaxone plus black garlic extract (BGE, group IV). All animals were housed and inoculated with 1 × 1010 CFU/15 mL of intraperitoneal Escherichia coli ATCC 25922. Subsequently, they received a daily treatment according to each group for 7 days. Clinical, analytical, microbiological, and histopathological parameters were evaluated. Statistically significant clinical improvement was observed in rats receiving garlic extracts in weight (groups II and III), ocular secretions, and piloerection (group IV). Moreover, less liver edema, vacuolization, and inflammation were observed in groups receiving adjuvant support (groups II, III, and IV). When comparing interleukins 24 h after bacteria inoculum, we found statistically significant differences in TNF-alpha levels in groups receiving BGE (groups III and IV, p ≤ 0.05). Blood and peritoneal liquid cultures were also analyzed, and we detected a certain level of Enterococcus faecalis in peritoneal cultures from all treatment groups and less bacteria presence in blood cultures in rats receiving garlic extracts (groups II, III, and IV). In conclusion, TASE and BGE could be promising nutraceutical or medicinal agents as coadjuvants in the treatment of sepsis because of its effects in modulating the inflammatory response.

ABSTRACT

OBJETIVO: Desarrollar un modelo de sepsis abdominal en animal de experimentación. MATERIAL Y MÉTODOS: Se utilizan ratas Sprague-Dawley(R), machos de 5 semanas con pesos entre 270-280 g en el momento de la inoculación (N=39). Inicialmente se realiza un estudio piloto (N=9), distribuyéndolas en 3 grupos (3/3/3) con inóculo de 1cc de Escherichia coli ATCC 25922 intraperitoneal en concentraciones de 10E8, 10E9 y 10E10 UFC. En un segundo estudio (N=6) con distribución en dos grupos (3/3) se utilizan 1cc una concentración de E. coli 10E10 UFC que se diluyen en 10 y 15 ml de agua destilada para su inoculación. Por último se inicia un ensayo experimental con aleatorización de 24 ratas en tres grupos de tratamiento tras la infección intraperitoneal: Grupo I con suero fisiológico (N=6), Grupo II con antibiótico (ceftriaxona) (N=9), Grupo III con antibiótico más adyuvante (ceftriaxona más alicina) (N=9). Se realizan muestras microbiológicas de sangre y líquido peritoneal, así como estudio histopatológico de órganos intraperitoneales (hígado, diafragma y peritoneo). RESULTADOS: Se observa muerte en el 100% de las ratas infectadas con la concentración de E. coli 10E10 UFC con la dilución de 15 ml de agua destilada y sin antibiótico. El hemocultivo y cultivo de líquido peritoneal es positivo a la misma cepa en todas ellas. Se observa la formación de abscesos en la superficie del hígado e infiltración por polimorfonucleares en los tejidos. CONCLUSIÓN: Se establece que la dosis letal de E. coli es 10E10 UFC diluida en 15 ml agua destilada en inyección intraperitoneal


OBJECTIVE: The aim of the study was to develop a model of abdominal sepsis in the experimental animal. MATERIAL AND METHODS: Sprague-Dawley male rats of 5 weeks (N=39) were used. Initially, a pilot study (N = 9) was performed and distributed in 3 groups with 1cc inoculum of Escherichia coli ATCC 25922 intraperitoneally at concentrations of 10E8, 10E9 and 10E10 CFU. Subsequently, concentrations of 10E10 CFU are used in two groups of 3 rats with dilutions of 10 cc and 15 cc of distilled water respectively. Finally, a randomized trial of 24 rats was started in three treatment groups after intraperitoneal infection: Group I with physiological serum (N = 6), Group II with ceftriaxone (N = 9), Group III with ceftriaxone plus allicin (N = 9). Microbiological samples of blood and peritoneal fluid were made, as well as histopathological study of intraperitoneal organs (liver, diaphragm and peritoneum). RESULTS: Death of 100% of the rats infected with 10E10 E. coli UFC concentration with the dilution of 15 ml of distilled water and without antibiotic was oberved. The blood culture and peritoneal fluid culture was positive for the same strain in all of them. The formation of abscesses on the liver surface and polymorphonuclear infiltration in tissues were observed. CONCLUSION: The lethal dose of E. coli is 10E10 CFU diluted in 15 cc distilled water by intraperitoneal injection

ABSTRACT

BACKGROUND: Closed hyperthermic intraperitoneal chemotherapy (HIPEC) may increase abdominal pressure and effects of hemodynamic changes due to maintenance hyperthermia. Our aim was to analyze the safety and effectiveness of our closed technique with CO2 circulation in management fluid status and hemodynamic parameters by means of cardiac preload control measured by Global End Diastolic Values (GEDV) and a gas exchanger. MATERIAL AND METHODS: A Pilot Clinical Study that included 18 advanced ovarian cancer patients undergoing citoreductive surgery and HIPEC. We used a closed-perfusion system (PRS Combat®) that includes CO2 circulation and a gas exchanger. Transpulmonary thermodilutions and hemodynamic measurements (PiCCO2®) were performed after citoreductive surgery (Pre-HIPEC); At half time of the HIPEC (Intra-HIPEC); After HIPEC (Post-HIPEC). RESULTS: No significant hemodynamic measurements changes in the three thermodilutions values of Cardiac Index (CI) (p = 0.227), Global End Diastolic Values (GEVD) (p = 0.966), Stroke Volume Variation (SVV) (p = 0,884) and Systemic Vascular Resistance Index (SVRI) (p = 0.082). No correlation between central venous pressure (CVP) and GEDV (Pre-HIPEC: r = 0.164, p = 0.211; Intra-HIPEC: r = 0.015, p = 0.900; Post-HIPEC: r = 0.018, p = 0.890). There was better correlation between GEDV and CI (Pre-HIPEC: r = 0.432, p = 0.071; Intra-HIPEC: r = 0.418, p = 0.074; Post-HIPEC: r = 0.411, p = 0.080). CONCLUSIONS: Closed intrabdominal chemotherapy with CO2 circulation model may be a safe model for HIPEC by means of a gas exchanger. GEDV and its changes significantly correlated to CI, and not observed for CVP. GEDV values may be more appropriate for monitoring cardiac preload, blood loss limitation and to predict changes in intravascular volume status during intraperitoneal chemotherapy.

ABSTRACT

BACKGROUND: Central venous pressure often fails to identify the true value of cardiac preload. Our purpose is to investigate whether Global End-Diastolic Volume (GEDV) values can control hemodynamic parameters for the measurement of fluid volume, cardiac preload and blood loss during liver transection. METHODS: This was a prospective clinical study that included patients undergoing liver resection. All patients were monitored by means of PiCCO technology and 222 hemodynamic measurements were performed in 74 patients. Fluid restriction was used. Transpulmonary thermodilutions were performed at different times of surgery, namely: 1. at the beginning of surgery; 2. before hepatectomy and after selective vascular exclusion (Time 1); 3. approximately half way through the liver transection (Time 2); and 4. after liver resection (Time 3). RESULTS: One hundred and twenty-nine of the 222 GEDV values were decreased (prevalence of hypovolemia of 58.1%). However, twenty two of the 222 CVP values were decreased (prevalence of 10.8%). Sensitivity of CVP with regard to volume depletion (GEDV > 650 mL m-2) on the times (1, 2 and 3) were 16.28 (4.08-28.48, 95% CI), 18.18 (5.65-30.75, 95% CI) and 21.43 (7.83-35.03, 95% CI), respectively. There was no correlation between CVP and GEDV. CONCLUSIONS: GEDV values may be more appropriate for monitoring cardiac preload during liver transection.

ABSTRACT

As dislipidemias são, dentro dos transtornos endócrinos metabólicos, um dos principais problemas de saúde hoje em dia e representam um fator de risco importante para o desenvolvimento de doenças crônicas tanto metabólicas como vasculares. O município de Piedade dos Gerais possui uma elevada incidência e prevalência desta doença, relacionada fundamentalmente com padrões de alimentação inadequados como, consumo de carne de porco e de boi gordurosas, consumo de leite sem processo de pasteurização e queijos elaborados nas próprias casas, alto índice de consumo de álcool e padrões de vida sedentários. Este trabalho tem como objetivo propor um plano de intervenção para diminuir a incidência das dislipidemias na área de abrangência da Equipe de Saúde da Família dois de Piedade dos Gerais. Foi realizada uma revisão de literatura com a finalidade de buscar as evidências já existentes sobre as abordagens de ações de controle e diminuição dos fatores de risco das dislipidemias que subsidiou a elaboração do plano de ação com atividades propostas a serem aplicadas pelos diferentes atores governamentais, religiosos, líderes das comunidades e a equipe. Espera-se que esta proposta contribua para a redução da incidência das dislipidemias na área de abrangência da equipe de saúde
