Cold-Pressed Okra Seed Oil Byproduct as an Ingredient for Muffins to Decrease Glycemic Index, Maillard Reaction, and Oxidation.

This study aimed to investigate the effects of adding cold-pressed okra seed oil byproduct (OSB) to the muffin formulation, as a partial substitute for wheat flour, on the nutritional, physicochemical, rheological, textural, and sensory properties of muffins. The carbohydrate, protein, oil, moisture, and ash contents of OSB were 44.96, 32.34, 10.21, 7.51, and, 4.98%, respectively, indicating that OSB was rich in protein and carbohydrate. All muffin samples showed a shear thinning behavior, indicating that the viscosity of all samples decreased with increasing shear rate. The frequency sweep test showed that all samples showed viscoelastic solid-like structure [G' (storage modulus)> G″ (loss modulus)]. The K' values (between 66.45 and 139.14) were higher than the K″ values (between 36.62 and 80.42) for all samples. The result was another indication of the viscoelastic solid characteristic of the samples. In our study, it was found that the fluorescence of advanced Maillard products and soluble tryptophan index decreased with increasing amount of OSB, indicating that OSB addition led to a decrease in the amount of fluorescent Maillard reaction (MR) products. The fortified muffins with more than 10% OSB had a reduced estimated glycemic index (GI) significantly in comparison with control muffin samples (p < 0.05). The induction period (IP) values of the muffin samples containing OSB (between 11:57 and 15:15 h/min) were higher than the IP value of the control sample (10:50 h/min), indicating that OSB improved the oxidative stability of the muffin samples. The addition of OSB has shown no negative effect on sensory attributes considering texture, mouth fell, odor, and taste. This study suggested that the addition of OSB in muffins could improve rheological properties and oxidative stability and decrease GI and the amount of MR products without negative impact on sensory properties.

Immunohistochemical Profile of Tumor Pathways and Prognostic Significance in Colon Adenocarcinomas.

The current study examined the immunohistochemical expression levels of molecules on carcinogenesis pathway and evaluated their clinicopathologic significance in colorectal adenocarcinoma (CRA). A total of 189 CRA and 20 colonic mucosal tissue samples were evaluated by immunohistochemical staining using 38 antibodies targeting the known molecules that play roles in developmental pathways of various tumors. The immunoexpression data of the patients were compared to clinicopathologic parameters. Expression loss of MLH1, MSH2, MSH6, PMS2, PTEN, Smad4 and E-cadherin, and overexpression of ALDH1, CD44, CAIX, P504S (AMACR), TGFΒ, and ZEB1 were statistically significant in CRA compared to normal colon mucosa. Long-term clinical follow-up findings in our cases suggested that AMACR, CAIX, ALDH1, TGFΒ, ZEB1 overexpression, and cyclinD1, p53, E-cadherin, and PTEN inactivity might be useful markers of a poor prognosis in CRA. In survival analyses, the expression of CAIX and AMACR were significantly associated with overall survival in both the univariate and multivariate analyses (log-rank test; p < 0.01 and p < 0.05, respectively).

Gastric Adenocarcinoma Biomarker Expression Profiles and their Prognostic Value.

Expression levels of several molecules implicated in carcinogenesis were examined by immunohistochemical staining, and the prognostic significance of their expression levels in gastric adenocarcinoma (GA) was evaluated. A total of 115 GA and 20 control gastric tissue samples were evaluated by immunohistochemistry using 33 antibodies targeting molecules known to play a part in the development of various tumors. Overexpression of carbonic anhydrase IX (CAIX) and loss of AT-rich interactive domain-containing protein 1A (ARID1A), aldehyde dehydrogenase 1 (ALDH1), and CD44 expression in GA patients were significantly correlated with lymph node (LN) metastasis, advanced tumor stage, and poor prognosis. The results demonstrated that ALDH1A and ARID1A may be strong independent prognostic factors associated with overall survival and recurrence-free survival (p < 0.01 and p < 0.05, respectively). Our results demonstrated that ALDH1, CD44, ARID1A, and CAIX in immunoreactive GA tumor cells exhibit different expression profiles compared with control cells and that these differences are associated with patient survival. The molecules with differential expression profiles were associated with some common functions, including hypoxia, epithelial-to-mesenchymal transition, and SW1/SNF-mediated chromatin remodeling. In addition, the loss of ALDH1, ARID1A, and CD44 and the overexpression of CAIX are important for tumor invasion and metastasis; therefore, they may serve as useful prognostic indicators of long-term survival in patients with GA. In conclusion, our study found that abnormal expression of some of the proteins evaluated in GA tumor cells might have an important role in carcinogenesis and tumor progression and thus may influence the prognosis of patients with GA.

Effect of gabapentin pretreatment on myoclonus after etomidate: a randomized, double-blind, placebo-controlled study / Efeito do pré-tratamento com gabapentina sobre a mioclonia após etomidato: um estudo randômico, duplo-cego e controlado por placebo

Abstract Aim: To evaluate the effects of three different doses of gabapentin pretreatment on the incidence and severity of myoclonic movements linked to etomidate injection. Method: One hundered patients, between 18 and 60 years of age and risk category American Society of Anesthesiologists I-II, with planned elective surgery under general anesthetic were included in the study. The patients were randomly divided into four groups and 2 h before the operation were given oral capsules of placebo (Group P, n = 25), 400 mg gabapentin (Group G400, n = 25), 800 mg gabapentin (Group G800, n = 25) or 1200 mg gabapentin (Group G1200, n = 25). Side effects before the operation were recorded. After preoxygenation for anesthesia induction 0.3 mg kg−1 etomidate was administered for 10 s. A single anesthetist with no knowledge of the study medication evaluated sedation and myoclonic movements on a scale between 0 and 3. Two minutes after induction, 2 µg kg−1 fentanyl and 0.8 mg kg−1 rocuronium were administered for tracheal intubation. Results: Demographic data were similar. Incidence and severity of myoclonus in Group G1200 and Group G800 were significantly lower than in Group P; sedation incidence and level were appreciably higher compared to Group P and Group G400. While there was no difference in the incidence of myoclonus between Group P and Group G400, the severity of myoclonus in Group G400 was lower than in the placebo group. In the two-hour period before induction other than sedation none of the side effects related to gabapentin were observed in any patient. Conclusion: Pretreatment with 800 mg and 1200 mg gabapentin 2 h before the operation increased the level of sedation and reduced the incidence and severity of myoclonic movements due to etomidate.

Resumo Objetivo: Avaliar os efeitos de três doses diferentes de gabapentina como pré-tratamento sobre a incidência e a gravidade dos movimentos mioclônicos associados à injeção de etomidato. Método: Cem pacientes, entre 18-60 anos, estado físico ASA I-II, programados para cirurgia eletiva sob anestesia geral, foram incluídos no estudo. Os pacientes foram randomicamente divididos em quatro grupos e duas horas antes da operação receberam cápsulas orais de placebo (Grupo P, n = 25), 400 mg de gabapentina (Grupo G400, n = 25), 800 mg de gabapentina (Grupo G800, n = 25) e 1.200 mg de gabapentina (Grupo G1.200, n = 25). Os efeitos colaterais antes da cirurgia foram registados. Após pré-oxigenação para a indução da anestesia, etomidate (0,3 mg.kg−1) foi administrado por 10 segundos. Um único anestesista, cego para a medicação do estudo, avaliou a sedação e os movimentos mioclônicos com uma escala de 0 a 3. Dois minutos após a indução, fentanil (2 µgr.kg−1) e rocurônio (0,8 mg.kg−1) foram administrados para a intubação traqueal. Resultados: Os dados demográficos foram semelhantes. A incidência e a gravidade da mioclonia nos grupos G1.200 e G800 foram significativamente menores do que no Grupo P; a incidência e o nível de sedação foram consideravelmente maiores comparados com o Grupo P e o Grupo G400. Enquanto não houve diferença na incidência de mioclonia entre os grupos P e G400, a gravidade da mioclonia no Grupo G400 foi menor do que no grupo placebo. No período de duas horas antes da indução, nenhum dos efeitos colaterais relacionados à gabapentina, exceto sedação, foi observado em qualquer paciente. Conclusão: O pré-tratamento com 800 mg e 1.200 mg de gabapentina duas horas antes da operação aumentou o nível de sedação e reduziu a incidência e a gravidade dos movimentos mioclônicos associados ao etomidato.

The diagnostic value of frozen section for borderline ovarian tumours.

Borderline ovarian tumours (BOTs) are characterised histologically by a low degree of cellular proliferation and nuclear atypia in the absence of infiltrative growth or stromal invasion. Surgical treatment has been a crucial component of BOT therapy. Surgical decisions are established intraoperatively via the frozen section. We evaluated the accuracy of frozen section diagnosis. The rate of correct diagnosis, underdiagnosis and overdiagnosis of BOTs with frozen sections was 78%, 17% and 5%, respectively. The sensitivity and positive predictive values for the diagnosis of BOTs with frozen sections were 82.3% and 93.3%, respectively. The positive likelihood ratio was 0.82 (95% CI: 0.85-0.96). The histological classification of BOTs had a significant effect on the accuracy of diagnosis (p = 0.001). Frozen section diagnosis is not suitable to be considered as the gold standard for a definitive diagnosis. Clinicians should be aware that using frozen sections is insufficient for the accurate staging of BOTs.

Risk factors for cisplatin-induced long-term nephrotoxicity in pediatric cancer survivors.

BACKGROUND: The aim of this study was to compare the nephrotoxicity risk of cisplatin (CPL) and ifosfamide (IFO) combination treatment (CT) with that of CPL alone and to evaluate the prevalence of CPL-induced long-term nephrotoxicity in pediatric cancer survivors (CS). METHODS: A total of 33 patients with pediatric solid tumors who have been cured of their disease were included in the study. They were divided into two groups based on the type of chemotherapeutics, either CPL (n = 21) or CT (n = 12), given during cancer treatment and were evaluated for glomerular and tubular function using the Skinner grading system. RESULTS: Nephrotoxicity was found in 15 CS (45.4%): seven (21.3%) of those had moderate, six (18.2%) had mild, and two (6.1%) had severe nephrotoxicity. Neither the rates of overall nephrotoxicity, glomerular toxicity and tubular toxicity, nor the mean overall, glomerular and tubular toxicity scores differed significantly among the CPL and CT groups (P > 0.05 for all parameters). Cumulative IFO dose and age at treatment were found to be independent risk factors for both development and severity of CPL-induced nephrotoxicity (P = 0.025 and P = 0.036 for development of nephrotoxicity; P = 0.004 and P = 0.050 for severity of nephrotoxicity, respectively). CONCLUSIONS: Although CPL-induced long-term nephrotoxicity was found in half of the pediatric CS of solid tumors, clinically significant nephrotoxicity was detected only in a minority of them. Both higher cumulative IFO dose and younger age at treatment were found to be independent risk factors for both development and severity of CPL-induced nephrotoxicity.

[The effect of different doses of esmolol on hemodynamic, bispectral index and movement response during orotracheal intubation: prospective, randomized, double-blind study]. / Efeito de diferentes doses de esmolol sobre a resposta hemodinâmica, BIS e resposta de movimento durante a intubação orotraqueal: estudo prospectivo, randômico e duplo-cego.

OBJECTIVE: A prospective, randomized and double-blind study was planned to identify the optimum dose of esmolol infusion to suppress the increase in bispectral index values and the movement and hemodynamic responses to tracheal intubation. MATERIALS AND METHODS: 120 patients were randomly allocated to one of three groups in a double-blind fashion. 2.5mgkg(-1) propofol was administered for anesthesia induction. After loss of consciousness, and before administration of 0.6mgkg(-1) rocuronium, a tourniquet was applied to one arm and inflated to 50mmHg greater than systolic pressure. The patients were divided into 3 groups; 1mgkg(-1)h(-1) esmolol was given as the loading dose and in Group Es50 50µgkg(-1)min(-1), in Group Es150 150µgkg(-1)min(-1), and in Group Es250 250µgkg(-1)min(-1) esmolol infusion was started. Five minutes after the esmolol has been begun, the trachea was intubated; gross movement within the first minute after orotracheal intubation was recorded. RESULTS: Incidence of movement response and the ΔBIS max values were comparable in Group Es250 and Group Es150, but these values were significantly higher in Group Es50 than in the other two groups. In all three groups in the 1st minute after tracheal intubation heart rate and mean arterial pressure were significantly higher compared to values from before intubation (p<0.05). In the study period there was no significant difference between the groups in terms of heart rate and mean arterial pressure. CONCLUSION: In clinical practise we believe that after 1mgkg(-1) loading dose, 150µgkg(-1)min(-1) iv esmolol dose is sufficient to suppress responses to tracheal intubation without increasing side effects.

Syndrome of inappropriate antidiuretic hormone secretion related to Guillain-Barré syndrome after laparoscopic cholecystectomy.

BACKGROUND AND OBJECTIVES: Guillain-Barré Syndrome is one of the most common causes of acute polyneuropathy in adults. Recently, the occurrence of Guillain-Barré Syndrome after major and minor surgical operations has been increasingly debated. In Guillain-Barré syndrome, syndrome of inappropriate antidiuretic hormone secretion and dysautonomy are generally observed after maximal motor deficit. CASE REPORT: A 44-year-old male patient underwent a laparoscopic cholecystectomy for acute cholecystitis. After the development of a severe headache, nausea, diplopia, and attacks of hypertension in the early postoperative period, a computer tomography of the brain was normal. Laboratory tests revealed hyponatremia linked to syndrome of inappropriate antidiuretic hormone secretion, the patient's fluids were restricted, and furosemide and 3% NaCl treatment was initiated. On the second day postoperative, the patient developed numbness moving upward from the hands and feet, loss of strength, difficulty swallowing and respiratory distress. Guillain-Barré syndrome was suspected, and the patient was moved to intensive care. Cerebrospinal fluid examination showed 320 mg/dL protein, and acute motor-sensorial axonal neuropathy was identified by electromyelography. Guillain-Barré syndrome was diagnosed, and intravenous immune globulin treatment (0.4 g/kg/day, 5 days) was initiated. After 10 days in the intensive care unit, at which the respiratory, hemodynamic, neurologic and laboratory results returned to normal, the patient was transferred to the neurology service. CONCLUSIONS: Our case report indicates that although syndrome of inappropriate antidiuretic hormone secretion and autonomic dysfunction are rarely the initial characteristics of Guillain-Barré syndrome, the possibility of postoperative syndrome of inappropriate antidiuretic hormone secretion should be kept in mind. The presence of secondary hyponatremia in this type of clinical presentation may delay diagnosis.

Duodenal perforation and bilateral tension pneumothorax following endoscopic sphincterotomy.

Endoscopic sphincterotomy is commonly used for retained bile stones. We report a 24-year-old woman who showed bilateral tension pneumothorax and duodenal perforation following endoscopic sphincterotomy performed under sedation. These complications are rare in the literature have significant mortality and morbidity.
