Metabolic Information

This work will review the metabolic information that various studies have obtained in recent years on bladder cancer, with particular attention to discovering biomarkers in urine for the diagnosis and prognosis of this disease. In principle, they would be capable of complementing cystoscopy, an invasive but nowadays irreplaceable technique or, in the best case, of replacing it. We will evaluate the degree of reproducibility that the different experiments have shown in the indication of biomarkers, and a synthesis will be attempted to obtain a consensus list that is more likely to become a guideline for clinical practice. In further analysis, we will inquire into the origin of these dysregulated metabolites in patients with bladder cancer. For this purpose, it will be helpful to compare the imbalances measured in urine with those known inside tumor cells or tissues. Although the urine analysis is sometimes considered a liquid biopsy because of its direct contact with the tumor in the bladder wall, it contains metabolites from all organs and tissues of the body, and the tumor is separated from urine by the most impermeable barrier found in mammals. The distinction between the specific and systemic responses can help understand the disease and its consequences in more depth.

461 Background: Effective intravesical therapies remain lacking for non-muscle invasive bladder cancer (NMIBC) when Bacillus Calmette-Guerin fails. OncoTherad is a nanostructured inorganic phosphate complex associated with glycosidic protein, developed by the University of Campinas/Brazil, which triggers immunomodulatory and antitumor activities. Previous studies have shown that Platelet Rich Plasma (PRP) acts on immune activation and exerts antitumor effects. This study characterized the effects of the OncoTherad associated with PRP in the treatment of NMIBC chemically induced in mice and the modulation promoted in the Toll-like receptors (TLRs) signaling pathway. Methods: Forty-two C57BL/6J mice were divided into groups: Control; Cancer (N-ethyl-N-nitrosourea carcinogen, 50 mg/ml); PRP (0.1 ml); OncoTherad (20 mg/ml); OncoTherad+PRP 10 mg/ml and OncoTherad+PRP 20 mg/ml. The intravesical doses (0.1 ml) were instilled once a week for 6 weeks after induction. Results: The NMIBC induction decreases (p<0.05) body weight, although after treatments the body weight was recovered similarly to the healthy mice. The treatments did not significantly alter the biochemical patterns of the urine and food and water consumption. There was no acute toxicity or kidney damage, and the presence of hydroureter was variable. The urinary bladders of mice treated with Oncotherad associated or not with PRP showed hyperemia associated with the inflammatory condition. The thickening of the urinary bladder wall in the Cancer group was more evident than in the treated groups, in which there were bladders without thickening or macroscopic lesions. Flat carcinoma in situ (pTis) was present in 100% of the mice in the Cancer group and the intensity of immunoreactivities for TLR2, IL-6, TLR4, and IRF-3 was significantly weaker in comparison with the Control, indicating suppression of the immune system in the tumor microenvironment. When treated intravesically with PRP only, mice showed 28.6% of tumor progression inhibition rate; with OncoTherad 85.7% and with OncoTherad+PRP 10 mg/ml or 20 mg/ml 71.4%. Intravesical treatments led to distinct activation of TLRs 2 and 4-mediated innate immune system in the interleukins (MyD88-dependent) and interferons (TRIF-dependent) signaling pathways. The combined treatment of OncoTherad+PRP increased (p<0.05) the percentage of positive TLR4 urothelial cells and the intensity of immunoreaction for TLR4 compared to the isolated treatments and the immunoreactivities of NF-kB, IL-6, TLR4, IRF-3, and IFN-γ in comparison to the Cancer. Conclusions: Intravesical treatment with OncoTherad plus PRP promoted significant inhibition of tumor progression, possibly due to immunomodulatory activity involving the TLR pathway. This association can constitute a therapeutic strategy for refractory NMIBC patients.

Background: Bladder cancer is one of the most frequent type of urinary cancer which has been ever increasing. For the better treatment, the early discovery and definite diagnosis of this disease played an important role. Objective: To describe some clinical symptoms and ultrasound features of tumorlike lesions of the bladder. To diagnose and classify the histopathology of tumorlike lesions of the bladder. Materials, method: cross - sectional study on 64 cases in Hue University Hospital and Hue central hospital from April, 2016 to February, 2017. Results: Hematuria was the most common reason that patients went to hospital (79.7%). Lower abdominal pain and irritation during urination accounting for 9.4% and 6.2% respectively. Only 3 patients with bladder cancer were accidentally discovered through periodic health examination (4.7%). The characteristics of hematuria in bladder tumor was flesh red urine (62.5%) and total hematuria (60.7%). With ultrasonography, the results of 64 patients were divided in 3 groups as follow: bladder tumor, which was the highest rate 87.5%, bladder polyp was 3.1% and focal bladder wall thickening was 9.4%. Of which, the vast majority of these ultrasound images was tumor - like lesions protruding in the lumen of the bladder (75%), the rest was wall thickening lesions (25%). Tumors were different in size, the biggest tumor was 7cm in diameter and the smallest was 0.6cm. Those with the diameter 3cm or bigger accounting for 42.2%, the smaller was 57.8%. Most cases have only one lesion (62.5%) and at lateral wall (46.6%). Histopathologically, cancer was 59/64 case (92.2%): urothelial carcinoma was 98.3 %, squamous cell carcinomawas 1.7% and 5 cases (7.8%) were benign. Most cancerous cases were poorly differentiated, grade II (50.9%) and grade III (32.2%). The stage T1NxMx was 20.3% and worse than T2MxNx was 79.7%. Conclusion: hematuria was the most popular symptom, suggesting bladder cancer. Clinical diagnosing bladder cancer was not high sensitive (61.01%). Ultrasound could detect bladder tumor with high sensitive (89.8%). These patients also needed histopathology classification to diagnose and finally choose the best method for the appropriate treatment.

Markers Of Inflammation

Background: The increased prevalence of obesity among children determined the rising number of its comorbidities in children and adults, too. This study aimed to evaluate certain markers of inflammation and insulin resistance in obese pediatric patients, identifying those who are more likely to develop further complications. Methods: We included 115 obese pediatric patients: 85 overweight and obese patients in the study group and 30 normal-weight patients in the control group. We calculated the body mass index (BMI) and we evaluated markers (biological, inflammatory) and the hormones profile. Results: Low-threshold inflammation was assessed by measuring interleukin 6 IL-6 and Intercellular Adhesion Molecules (ICAM). The analysis showed that IL-6 is significantly correlated with glucose (p = 0.001) and BMI value (p = 0.031). ICAM correlates significantly with triglycerides (p = 0.001), glucose (p = 0.044) and BMI percentile (p = 0.037). For pediatric obese patients, endotoxemia has been significantly correlated only with BMI percentile (p = 0.001). Plasma cortisol did not show significant correlations with total cholesterol, triglycerides, glucose or BMI percentile. The results indicated a significant predictive power of BMI percentile on inflammatory markers: IL-6 (AUC = 0.803, p < 0.001), ICAM (AUC = 0.806, p < 0.001) and endotoxemia (AUC = 0.762, p = 0.019). Additionally, BMI percentile has a significant predictive power for metabolic markers of insulin resistance (insulin value: AUC = 0.72, p < 0.001 and HOMA index: AUC = 0.68, p = 0.003). Conclusions: The study highlighted the importance of early markers of cardiovascular risk in obese pediatric patients represented by IL-6, ICAM, endotoxemia and their correlation with metabolic markers of insulin resistance represented by insulinemia, HOMA index and plasma cortisol. It can clearly be considered that the BMI percentile has significant predictive power for metabolic markers of insulin resistance.

Abstract Background Urothelial bladder carcinoma accounts for around 3.9% cases of all the male cancers in India. Non-muscle-invasive bladder carcinoma (NMIBC) is predominant group which constitute approximately three fourth of the urothelial bladder cancer. Intravesical BCG immunotherapy is the corner stone of today’s NMIBC management. However, as with any other therapy it has its own complications and its interruption due to these adverse effects is a major cause of suboptimal efficacy. The aim of this study was to assess the complications of intravesical BCG therapy and their management in NMIBC patients. Methods This was a retrospective descriptive study conducted between October 2016 and November 2019; a backward review of 149 patients with diagnosis of NMIBC that undergone intravesicle BCG therapy was performed. Patient’s demographical, clinical, diagnostic and procedural data regarding bladder tumour, BCG therapy, its complications and management were collected and analysed. Results Total 149 patients were analysed, comprising 116 males and 33 females. The mean age was of 57.2 ± 6.7 years. Total 85.23% were primary and 14.76% were recurrent tumours. Total 96 patients (64.42%) completed the planned course, while 53 (35.57%) interrupted. The reasons for BCG interruption includes adverse effects (15.4%), progression of disease (6.7%), disease refractory to BCG (4.6%) and disease recurrence during BCG (3.3%). Most of the adverse events occurred in first 6 months and most interruptions occurred after the induction period. Cystitis was the most common observed adverse effect seen in 39.6% patients. Frequency, urgency, haematuria were common presentation. Radical cystectomy was the most common (16.10%) further treatment with patients whose treatment was interrupted. Conclusion BCG is an indispensable therapy available for NMIBC, but it is associated with array of adverse effects and complications, which are the main reasons for poor compliance to BCG therapy. Although BCG-related complications can affect any organ in the body, potentially life-threatening systemic BCG-related infections are encountered in only < 5% of patients. There are some difficulties in diagnosis of the BCG complications because acid-fast staining, culture and PCR test are not always positive; tissue biopsies should be indicated sometimes to evaluate histopathology and presence of M. bovis. A persistently monitored multidisciplinary approach with high index of suspicion and prompt anti-TB therapy can help to derive the maximum benefits while keeping the complications at check.

BACKGROUND: Bladder cancer is the ninth most common cancer in men. 70% of these tumors are classified as non-muscle invasive bladder cancer and those patients receive 6 intravesical instillations with Mycobacterium bovis BCG after transurethral resection. However, 30% of patients show recurrences after treatment and experience severe side effects that often lead to therapy discontinuation. Recently, another vaccine strain, Salmonella enterica typhi Ty21a, demonstrated promising antitumor activity in vivo. Here we focus on increasing bacterial retention in the bladder in order to reduce the number of instillations required and improve antitumor activity. OBJECTIVE: To increase the binding of Ty21a to the bladder wall by surface labeling of the bacteria with adhesion protein FimH and to study its effect in a bladder cancer mouse model. METHODS: Binding of Ty21a with surface-labeled FimH to the bladder wall was analyzed in vitro and in vivo. The antitumor effect of a single instillation of Ty21a+FimH in treatment was determined in a survival experiment. RESULTS: FimH-labeled Ty21a showed significant (p <  0.0001) improved binding to mouse and human cell lines in vitro. Furthermore, FimH labeled bacteria showed ∼5x more binding to the bladder than controls in vivo. Enhanced binding to the bladder via FimH labeling induced a modest improvement in median but not in overall mice survival. CONCLUSIONS: FimH labeling of Ty21a significantly improved binding to bladder tumor cells in vitro and the bladder wall in vivo. The improved binding leads to a modest increase in median survival in a single bladder cancer mouse study.

Three forms of pediculosis affect the human host, each with a predilection for certain parts of the body. Pediculosis capitis. or head lice, is the most common type and is seen primarily in preschool and school-age children, especially girls. Transmission occurs by coming into direct contact with lice or by sharing infested brushes, combs, and hats. Adult lice and their eggs (nits) are found principally in the occipital region and behind the ears. Symptoms include severe itching, often resulting in excoriation and secondary bacterial infection. Pediculosis pubis is seen most commonly in sexually active adolescents and young adults, although occasionally it may be found on the eyelashes of small children who come in contact with infected individuals.

Background&amp;Aim: High grade non-muscle invasive bladder cancer (NMIBC) is common in urological practice. Most of these cancers are or become refractory to intravesical immunotherapy and chemotherapy. Here we evaluated the efficacy of combined local bladder hyperthermia and intravesical mitomycin-C (MMC) instillation in patients with high-risk recurrent NMIBC. Materials and methods: Between February 2014 and December 2015, 18 patients with high risk NMIBC were enrolled. Patients were treated in an outpatient basis with 6 weekly induction sessions followed by monthly maintenance sessions with intravesical MMC in local hyperthermia with bladder wall thermo-chemotherapy (BWT) system (PelvixTT system, Elmedical Ltd., Hod Hasharon, Israel). The follow-up regimen included cystoscopy after the induction cycle and thereafter with regular intervals. Time to disease recurrence was defined as time from the first intravesical treatment to endoscopic or histological documentation of a new bladder tumour. Adverse events were recorded according to CTC 4.0 (Common Toxicity Criteria) score system. Results: Mean age was 72 (32-87) years. 10 patients had multifocal disease, 9 had CIS, 6 had recurrent disease and 2 had highly recurrent disease (&gt; 3 recurrences in a 24 months period). 6 patients underwent previous intravesical chemotherapy with MMC. The average number of maintenance sessions per patient was 7.6. After a mean follow-up of 433 days, 15 patients (83.3%) were recurrence-free. 3 patients had tumour recurrence after a mean period of 248 days without progression. Side effects were limited to grade 1 in 2 patients and grade 2 in 1 patient. Conclusions: BWT seems to be feasible and safe in high grade NMIBC. More studies are needed to identify the subgroup of patients who may benefit more from this treatment.

In African traditional religion, priding oneself in the beliefs and practices of one’s culture is intensely essential. The driving force for this is mainly the need to satisfy the will of a higher power. Cultural practices, being a channel between the living, the dead and the spirits is one of the ways in which a group of people satisfy the will of these higher beings. Body marking, among the Dangme, forms a great deal of aspects of cultural practices which connotes spirituality. This study discusses the concept of spirituality as enshrined in the body marks of the Dangme people of Ghana. To obtain the relevant information needed, the qualitative approach to research has been adopted using interviews and observation as the main data collection tools. These give a rich and in-depth understanding of the body marks that are practiced for spiritual purposes among the Dangme. This paper is a collation of findings from studies conducted between February, 2012 and February, 2019. It is evident from the research that, marks for spiritual purposes seemed to be practiced irrespective of the clan individuals hail from. These marks are seen as methods (or modes) of maintaining direct contact and proving allegiance to the spirits that protect them as a people.

In Ayurveda, the term Tvak, Twacha and Charma are frequently used to denote the skin. Tvak is described as the organ which covers the external surface of the entire body. Tvak and its related diseases have great importance because these are easily noticeable. It is the first part of the body that is in direct contact with any harmful sub- stances or infective microorganisms. It protects the internal structures of the body from injury or infections and regulates the temperature of the body. Skin is also the beauty of a human being. Therefore, it should be protected from any abnormal conditions. Ayurveda Acharyas have described Tvak many years ago. They explained each layer of Tvak in meaningful sequences, its related diseases and measurement of each layer. They also explained that it maintains the normal colour of individuals and conveys the sensation of touch. Some topics of Ayurveda are easy to understand, and some topics become easy if we study along with modern science. So, for a proper un- derstanding of the concept of Tvak, it is very essential to correlate it with modern science and elaborate according to the modern era.

Background: Scabies is a skin disease caused by Sarcoptes scabiei. Scabies is transmitted through direct contact with animals affected by scabies or contact with the source of scabies mite in area of cat lives. Purpose: This study aims to determine the management of scabies at Q-One PetKlinik Surabaya. Method: Handling domestic cats affected by S.scabiei began with an interview with the  owner and examinated with the physical condition of cats, and observed the body that was infected with S.scabiei. Scrabbing on scabs was conducted in the cat’s body which was located in the facial area, and followed by microscopic examination to observe the S.scabiei mite. Results: During April 2021, there were 13 domestic cats affected by scabies. Treatment for scabies was by administrated drugs containing 5% Permethrin. Cats were also given supportive therapy by grooming with antiectoparasite shampoo after two weeks from being given drugs. Conclusion: Handling cases of scabies in domestic cats at Q-One PetKlinik Surabaya is performed by cleaning the scab, applying an ointment containing 5% permethrin, and giving anti-histamine and anti-parasitic as well as providing supportive therapy in the form of grooming using shampoo containing anti-ectoparasites.
