Educational and Psychological Support Combined with Minimally Invasive Surgical Technique Reduces Perioperative Depression and Anxiety in Patients with Bladder Cancer Undergoing Radical Cystectomy.

Radical cystectomy (RC) for muscle-invasive bladder cancer (MIBC) is an extensive and morbid operation, often associated with permanent alteration of body image and disability. Combined with the aggressive malignant potential of MIBC and considerable risk of complications, it poses a serious threat to the psychological well-being of patients. Educational deficiencies causing uncertainty and confusion aggravate surgery-related anxiety and may lead to depression along with further social disability. We conceived a preoperative supportive program named "Cystocare" held by urologists, psychologists, stoma therapists and cancer survivors to facilitate patients' adaptation and coping. We aimed to evaluate whether participation in Cystocare meetings would alleviate emotional distress in patients undergoing RC. We included 95 consecutive patients who filled Hospital Anxiety and Depression Score questionnaires before RC and on discharge. The intervention arm (A) comprised 32 Cystocare participants. The remaining 63 patients who received standard preparation constituted the control arm (B). Whilst there were no differences in median anxiety and depression scores preoperatively, in postoperative measurement, the intervention arm showed a lower median depression score than controls: 3 vs. 8 points, p = 0.015. On multivariate analysis we confirmed lower risk of postoperative depression in Cystocare participants: OR = 0.215 (95%CI: 0.066-0.699), p = 0.011, along with lower odds of preoperative anxiety in patients undergoing laparoscopic RC: OR = 0.365 (95%CI: 0.136-0.978), p = 0.045, and higher risk of prolonged hospital stay in patients experiencing postoperative anxiety OR = 17.114 (95%CI: 1.283-228.234) p = 0.032. Preoperative educational and supportive intervention complements laparoscopic RC in the alleviation of surgery-related anxiety and depression. The support group meetings provide an attractive and cost-effective opportunity to moderate emotional response in patients undergoing RC, and as such, deserve widespread adoption.

Hair as a matrix in monitoring drug epilepsy therapy.

Hair is considered an efficient tool to investigate drug-related histories; thus, the selection of the method of sample preparation is important to obtain a reliable result. The aim of this study was to compare two methods of hair preparation (cutting and pulverizing) to analyse levetiracetam concentration in hair. An additional aim was to evaluate the potential usefulness of the levetiracetam concentration measured as an index of a dosing schedule. Four groups of 12 rats were included in the experiment. Depending on the group, the rats received 10 mg/kg of levetiracetam intraperitoneally every 24, 48 and 72 hours for 30 days. The control group was not treated. At the end of the drug administration, the rats' hair was shaved, cut or pulverized and analysed by the LC/MS-MS method to determine the concentration of levetiracetam. A stronger correlation between the mean hair levetiracetam concentration in hair and the number of drug doses was found in pulverized hair than in cut hair. A smaller standard deviation between the results was obtained in the case of pulverized hair. The results indicate that pulverization gives a more reliable result of drug concentration in hair than cutting and that drug concentration in hair can reflect the scheme of levetiracetam administration.

Intergenerational implications of alcohol intake: metabolic disorders in alcohol-naïve rat offspring.

Alcohol drinking may be associated with an increased risk of various metabolic diseases. Rat lines selectively bred for alcohol preference and alcohol avoidance constitute an interesting model to study inherited factors related to alcohol drinking and metabolic disorders. The aim of the present study was to compare the levels of selected laboratory biomarkers of metabolic disorders in blood samples from naïve offspring of Warsaw alcohol high-preferring (WHP), Warsaw alcohol low-preferring (WLP), and wild Wistar rats. Blood samples were collected from 3-month old (300-350 g) alcohol-naïve, male offspring of WHP (n = 8) and WLP rats (n = 8), as well as alcohol-naïve, male, wild Wistar rats. Markers of metabolic, hepatic, and pancreatic disorders were analysed (levels of homocysteine, glucose, total cholesterol, triglycerides and γ-glutamyl transferase (GGT), aspartate (AST), alanine aminotransferase (ALT), and amylase serum activities). Alcohol-naïve offspring of WHP, WLP, and wild Wistar rats differed significantly in the levels of triglycerides, total cholesterol, homocysteine, as well as in the activity of GGT, ALT, AST, and amylase enzymes. Most markers in the alcohol-naïve offspring of WHP rats were altered even thought they were never exposed to alcohol pre- or postnatally. This may suggest that parental alcohol abuse can have a detrimental influence on offspring vulnerability to metabolic disorders.

Levetiracetam concentration in hair is associated with the time schedule of administration: Study on rats.

Measurement of hair drug content may be a reliable biomarker of the history of drug exposure, allowing to assess patient long-term compliance. Studies on correlations between antiepileptic drugs intake and their hair contents are limited. The aim of the study was to determine the association between the history of levetiracetam administration and its content in rat hair in controlled laboratory conditions. Additionally, the effects of levetiracetam on hair growth rate and body-weights were examined. Three groups of 12 rats each were exposed to different schedules of levetiracetam administration (10 mg/kg i.p.: every 24, 48 and 72 hours) for 30 days. The control group received daily saline injection. Levetiracetam concentrations in hair were assessed by validated LC-MS/MS method. The mean hair concentrations were as follows: 300 (±100), 170 (±60) and 130 (±80) ng/mg for rats receiving levetiracetam every 24, 48 and 72 hours, respectively. The levetiracetam accumulation in the hair was correlated with the total number of doses received (r = .699, P < .001). Levetiracetam did not affect the hair growth rate and rat body-weight. The concentration of levetiracetam measured in rat hair represents a reliable marker. It may reflect the adherence to levetiracetam treatment; however, further studies on human beings are needed.

Comparison of plasma, saliva, and hair lamotrigine concentrations.

BACKGROUND: In some clinical situations (pregnancy, aging, drug resistance, toxicity), measurements of lamotrigine plasma levels may be reliable. Limited studies indicate that saliva and hair could be alternative sources for monitoring lamotrigine therapy. The drug content in hair can also be used to assess the history of drug therapy and to ascertain long-term patient compliance. The aims of this study were to 1) determine the correlations among plasma, saliva, and hair lamotrigine concentrations, 2) evaluate saliva as an alternative matrix for monitoring drug levels and 3) evaluate hair as a source of information on adherence to antiepileptic treatment and on the correlation of hair concentrations with clinical outcomes in patients with epilepsy. METHODS: Plasma, saliva, and hair lamotrigine concentrations were measured by liquid chromatography-tandem mass spectrometry in positive ionization mode. The study group (n = 85) was recruited among the epileptic patients at the Institute of Psychiatry and Neurology, Warsaw, Poland. RESULTS: Plasma concentrations were not influenced by sex, age, or the concomitant use of other antiepileptic drugs. Lamotrigine saliva and plasma concentrations were strongly correlated (r = 0.82, p < 0.001). Lamotrigine hair concentrations were correlated with the plasma concentrations (r = 0.53, p < 0.001) and daily dose in mg/kg (r = 0.23, p = 0.024). The analysis revealed no significant correlation between lamotrigine hair levels and the number of seizures in the previous 3 months (r = -0.1, p > 0.05). CONCLUSIONS: The lamotrigine saliva concentration is strongly correlated with its plasma level, and saliva can be used as an alternative matrix to plasma for monitoring. Lamotrigine can also be successfully measured in hair, and the drug levels in hair tend to be correlated with the levels in plasma. However, lamotrigine levels in hair may not correspond to clinical outcomes (i.e., seizure episodes).

Post-Operative Infections among Patients Undergoing Radical Cystectomy at a Tertiary Center.

BACKGROUND: Post-operative infection after radical cystectomy is a common complication. It is essential to identify modifiable risk factors that can predict post-operative infection to reduce the incidence of infection after radical cystectomy. We investigated the incidence of post-operative infection, associated pathogens, and risk factors for post-operative infection after radical cystectomy. PATIENTS AND METHODS: Patients who underwent radical cystectomy for bladder cancer in a single urologic department from 2014 to 2016 were included. Age, gender, length of stay, body mass index (BMI), diabetes mellitus, hypertension, pre-operative estimated glomerular filtration rate, hydronephrosis, smoking status, neoadjuvant chemotherapy, pathologic tumor stage, pathologic nodal stage, types of urinary diversion, laparoscopic approach, operative time, and receipt of peri-operative blood transfusion were assessed to determine the association of these factors with the risk of infection within 30 days of radical cystectomy. Risk factors were assessed for correlation with any kind of infection and separately for urinary tract infection (UTI), blood infection/septic shock (BI), and surgical site infection (SSI). Pathogens were identified in all cases of infection. RESULTS: A total of 134 patients were included in the analysis. Post-operative infection was diagnosed in 10.45%. Urinary tract infection, BI, and SSI were diagnosed in 3.73%, 4.48%, and 7.46%, respectively. Co-infections and mixed infection were diagnosed in 50% of patients with infection. Enterococcus was the most common pathogen. On multivariable analysis, age, BMI ≥30 kg/m2, and laparoscopic approach were associated with the risk of infection; odds ratios (ORs) were 1.27 (95% confidence interval [CI] 1.01-1.59), 13.07 (1.39-122.88), and 0.07 (0.01-0.78), respectively. CONCLUSION: One-tenth of patients undergoing radical cystectomy developed an infection within 30 days of surgery. Fifty percent of patients had co-infection with UTI, SSI, and/or BI and 50% of infections were polymicrobial. Increased BMI is the strongest factor associated independently with all types of infection. Therefore, obese patients should be encouraged to lose weight pre-operatively.
