RESUMO

OBJECTIVE: This study aimed to investigate the data of adult patients admitted to the only tertiary care center in Somalia with the diagnosis of urolithiasis and to present the first report from this Sub-Saharan African country. PATIENTS AND METHODS: This study was designed as a retrospective single-center study conducted in Somalia Turkiye Training and Research Hospital. Adult patients who received the diagnosis of urolithiasis and who were admitted to the urology department constituted the target population. Reviewed data included demographic parameters, stone features, type of surgical procedure, intraoperative and early postoperative complications, and inpatient mortality. RESULTS: Overall, 3,680 patients were admitted during the study period. Among these, 620 (17%) patients were admitted due to urolithiasis. There was a significant male predominance with a male-to-female ratio of 3.4:1. Urinary bladder was the most common stone location (n=253, 40.8%), followed by the kidney (n=223, 35.9%). The mean stone diameter was 22.41 (5-64); most (39.4%) of the patients had a stone diameter between 20 and 30 mm, while 27.5% had stones with diameters between 10 and 20 mm. Minimally invasive procedures were the primary surgical modality in 52.6% (n=326) of our patients. However, 45.9% (n=285) of the patients underwent open surgery. CONCLUSIONS: The rate of adults with urolithiasis is relatively high in Somalia, as in many other African countries, with a significant male predominance. Although open surgery is rarely used for treating adult urolithiasis in industrialized countries, this approach is still commonly used in Somalia, similar to other parts of Africa.

RESUMO

OBJECTIVE: This study aimed to evaluate neutrophil-lymphocyte ratio, lymphocyte-monocyte, and monocyte high-density lipoprotein ratios in patients with fibromyalgia and determine their relationship with disease activity, pain, and depression levels. PATIENTS AND METHODS: This study was conducted with 40 healthy controls and 87 newly fibromyalgia (FM) diagnosed patients. Demographic characteristics, duration of pain, body mass index (BMI), and laboratory test results were recorded. The hematological indices and ratios were determined with a hemogram test. Disease activity was evaluated with a fibromyalgia impact questionnaire (FIQ). Depression status was evaluated with the beck depression inventory (BDI). RESULTS: A total of 127 participants, 40 in the control group and 87 in the patient group, were included in the study. BMI values of the patient group were statistically higher than the control group (p=0.025). The white blood cell count of the patient group was statistically higher than the control group (p=0.007). Monocyte values were statistically higher in the patient group (p<0.001). Monocyte to high-density lipoprotein-cholesterol ratio (MHR) values in the patient group were statistically higher than the control group (p<0.001). Lymphocyte-monocyte-ratio (LMR) values of the control group were statistically higher than the patient group (p<0.001). CONCLUSIONS: This study shows that in fibromyalgia patients, monocyte level and MHR were higher than in healthy subjects. Also, high-density lipoprotein-cholesterol (HDL-C) level was found lower, and the total cholesterol level was found higher in patients with FM. Increased LMR and HDL-C values were found as responsible for decreasing the risk of developing FM and increased glucose and total cholesterol values were responsible for increasing the risk of FM developing.

RESUMO

OBJECTIVE: Cardiovascular diseases are responsible for the majority of deaths on a global scale. Atherosclerosis is the main risk factor for cardiovascular disorders and represents a complex phenomenon associated with endothelial dysfunction and inflammation. Statins, especially atorvastatin (ATV) and pitavastatin (PTV), are common agents used to control ongoing atherosclerotic events in the body to minimize cardiovascular disease-based deaths. MATERIALS AND METHODS: The present study aimed at comparing the efficacy of ATV and PTV in a cell line model of inflammation. Human saphenous vein cells were treated with TNF-alpha to mimic atherosclerotic conditions, and the cells were divided into 7 groups, including control, DMSO, TNF-alpha (10 ng/mL-6 hours), ATV (50 µM/24 hours), PTV (2 µM/24 hours), ATV (50 µM/24 hours)+TNF-alpha (10 ng/mL-6 hours) and PTV (2 µM/24 hours)+TNF-alpha (10 ng/mL-6 hours). The expression levels of 20 proinflammatory cytokines and chemokines were investigated in these groups using a human atherosclerosis antibody array. RESULTS: Possible pathway interactions were determined by STRING and PANTHER analyses. Comparison with the effect of ATV indicated that PTV reduced the levels of 4 proinflammatory cytokines: CCL11, CSF2, CCL20, and TGFB1 (p<0.05). CONCLUSIONS: Pleiotropic effects of pitavastatin against cardiovascular diseases appeared to be better; however, additional studies are required to compare statins and to identify new drugs that maintain broader protection from the risks of cardiovascular diseases.

RESUMO

BACKGROUND: Cerebrospinal fluid (CSF) leakage is a frequent and challenging complication in neurosurgery, especially in the posterior fossa, with a prevalence of 8%. It is associated with substantial morbidity and increased healthcare costs. A novel dural sealant patch (LIQOSEAL) was developed for watertight dural closure. The objective of this study is to clinically assess the safety and effectiveness of LIQOSEAL as a means of reducing intra- as well as postoperative CSF leakage in patients undergoing elective posterior fossa intradural surgery with a dural closure procedure compared to the best currently available dural sealants. METHODS: We will conduct a two-arm, randomized controlled, multicenter study with a 90-day follow-up. A total of 228 patients will be enrolled in 19 sites, of which 114 will receive LIQOSEAL and 114 an FDA-approved PEG sealant. The composite primary endpoint is defined as intraoperative CSF leakage at PEEP 20 cm H2O, percutaneous CSF leakage within 90 days of, wound infection within 90 days of or pseudomeningocele of more than 20cc on MRI or requiring intervention. We hypothesize that the primary endpoint will not be reached by more than 10 patients (9%) in the investigational arm, which will demonstrate non-inferiority of LIQOSEAL compared to control. DISCUSSION: This trial will evaluate whether LIQOSEAL is non-inferior to control as a means of reducing CSF leakage and safety TRIAL REGISTRATION: ClinicalTrials.gov NCT04086550 .

RESUMO

OBJECTIVE: Insulin resistance is an important risk factor for developing metabolic syndromes that cause morbidity diseases such as diabetes and cardiovascular diseases. Interestingly, in chronic inflammatory diseases, some inflammatory mediators can play, either directly or indirectly, a pivot role in the development of insulin resistance. This can be considered as an additional factor causing increased mortality and morbidity in these patients. In this paper, we want to investigate and compare the insulin resistance status in patients with Inflammatory Bowel Disease (IBD) and healthy control, as well as different stages of patients with Ulcerative colitis (UC) and Crohn's Disease (CD). PATIENTS AND METHODS: A total of 180 patients were enrolled in this study; while 95 patients had inflammatory bowel disease [Crohn's Disease (n): 47, Ulcerative colitis (n): 48], 85 people were healthy controls. Insulin resistance status was evaluated with the HOMA-IR (hemostasis model of assessment of insulin resistance) index. p < 0.05 was accepted as significant. RESULTS: The mean HOMA-IR levels were found to be similar for both IBD and control, and Crohn's disease and control (p = 0.174, p = 0.96, respectively); but the mean HOMA-IR score in ulcerative colitis, one of the IBD subgroups, was significantly higher than the control group (p < 0.039). CONCLUSIONS: This study clearly showed that insulin resistance is increased in ulcerative colitis. Consequently, patients with ulcerative colitis should be followed and closely monitored for developing insulin resistance, metabolic syndromes, diabetes, and cardiovascular diseases. Consequently, all of them can cause an additional risk of morbidity and mortality in these patients.

RESUMO

OBJECTIVE: The aim of this study was to compare preoperative and postoperative findings of the sciatic nerve by using B-mode ultrasound, strain elastography (SE), and shear wave elastography (SWE) in patients with unilateral lumbar foraminal disc herniation. PATIENTS AND METHODS: In this prospective study group, patients with complaints of foraminal disc herniation due to one level (L4-5 or L5-S1) were included. Preoperative and postoperative (one month after surgery) B-mode ultrasound, SE, and SWE findings of the affected sciatic nerve in patients who underwent unilateral spinal decompression surgery were compared. Evaluations were performed on the axial plane from the gluteal region using a convex probe of 5-9L MHz. The reference method used to assess nerve root compression was 1.5-T Magnetic Resonance Imaging (MRI). RESULTS: A total of 20 patients (9 males, 11 females) with a mean age of 46.2±13.1 years were included. The cross-sectional area (CSA), diameter, SWE values of the sciatic nerve were significantly higher in the affected side compared to those of the non-affected side (all for p<0.05). Blue and blue-green were the most common color codes in the affected side while green and green-yellow-red were the most common color codes in the non-affected side. The CSA, diameter, and SWE values of the sciatic nerve decreased after the surgery in the affected side (all for p<0.05), nonetheless. those did not differ in the non-affected side (all for p>0.05). CONCLUSIONS: Lumbar decompression surgery decreases the sciatic nerve diameter, CSA, and stiffness of the sciatic nerve.

RESUMO

OBJECTIVE: In this study, we aimed to investigate the clinicopathological features and survival of CD, which is quite rare and has many unknowns. PATIENTS AND METHODS: This study was conducted by retrospectively evaluating patients diagnosed with CD in six different centers in Turkey. RESULTS: The median age of 33 patients included in the study was 49 and 51.5% (n = 17) of these patients were women. 18 (54.5%) patients were in the hyaline vascular subtype and most of the patients were UCD (n = 20, 60.6%). The most common involvement region was head and neck (n = 19, 57.5%). The UCD group was younger than the MCD group (p=0.027). Visceral lymph node involvement was higher in MCD than in UCD (p=0.001). Similarly, it was observed that there was more hepatomegaly (p=0.035) and splenomegaly (p=0.013) in the MCD group. During the median 19.5 months follow-up period, there were no patients who died. CONCLUSIONS: It was observed that UCD and MCD are different clinical entities. Promising survival times can be achieved with surgical and systemic treatments in both subtypes of this extremely rare disease. However, this result should be supported by well-designed prospective comprehensive studies.

RESUMO

OBJECTIVE: Primary epiploic appendagitis (PEA) is a rare cause of abdominal pain revealed by torsion of colonic structures called epiploic appendices. In this paper, we present our clinical data and experience regarding this rare condition that may be confused with many diseases, such as acute appendicitis, diverticulitis, salphingitis, renal colic that may require emergency surgery. MATERIALS AND METHODS: A total of 39 consecutive patients diagnosed as PEA confirmed by abdominal computed tomography with a clinical course. Basic demographic data, abdominal pain characteristics, physical examination findings, laboratory results, treatment methods, and clinical course of the patients were retrospectively evaluated. Statistical analysis was performed using SPSS (18.0; Chicago, IL, USA), using the χ2-test and Fisher's exact test. RESULTS: Of the 39 patients diagnosed with PEA, 35 were male and 4 were female; the mean age of the patients was 36.0 ± 10.3. The main complaints were 69.2% abdominal pain, 12.8% groin pain, 5.1% flank pain with nausea and vomiting (2.6%), and abdominal swelling and dysuria. The average time of symptom was 5.3 days (1-15 days). In the computed tomography scan images, PEA was located in the sigmoid colon (21, 53.8%), descending colon (10, 25.6%), ascending colon (5, 12.8%), cecum (2, 5.1%), and hepatic flexure (1, 2.6%). No patient underwent surgical treatment. However, 9 of 39 patients were hospitalized for medical treatments, such as antibiotics and analgesic drugs intravenously. All patients were followed-up for a period of 1-year and there were no recurrence symptoms. CONCLUSIONS: When patients with localized lower abdominal pain and tenderness do not have associated symptoms or laboratory abnormalities, a high index of suspicion for PEA and early radiologic examinations are required.

RESUMO

Asbestos causes malignant transformation of primary human mesothelial cells (HM), leading to mesothelioma. The mechanisms of asbestos carcinogenesis remain enigmatic, as exposure to asbestos induces HM death. However, some asbestos-exposed HM escape cell death, accumulate DNA damage, and may become transformed. We previously demonstrated that, upon asbestos exposure, HM and reactive macrophages releases the high mobility group box 1 (HMGB1) protein that becomes detectable in the tissues near asbestos deposits where HMGB1 triggers chronic inflammation. HMGB1 is also detectable in the sera of asbestos-exposed individuals and mice. Searching for additional biomarkers, we found higher levels of the autophagy marker ATG5 in sera from asbestos-exposed individuals compared to unexposed controls. As we investigated the mechanisms underlying this finding, we discovered that the release of HMGB1 upon asbestos exposure promoted autophagy, allowing a higher fraction of HM to survive asbestos exposure. HMGB1 silencing inhibited autophagy and increased asbestos-induced HM death, thereby decreasing asbestos-induced HM transformation. We demonstrate that autophagy was induced by the cytoplasmic and extracellular fractions of HMGB1 via the engagement of the RAGE receptor and Beclin 1 pathway, while nuclear HMGB1 did not participate in this process. We validated our findings in a novel unique mesothelial conditional HMGB1-knockout (HMGB1-cKO) mouse model. Compared to HMGB1 wild-type mice, mesothelial cells from HMGB1-cKO mice showed significantly reduced autophagy and increased cell death. Autophagy inhibitors chloroquine and desmethylclomipramine increased cell death and reduced asbestos-driven foci formation. In summary, HMGB1 released upon asbestos exposure induces autophagy, promoting HM survival and malignant transformation.

RESUMO

BACKGROUND AND PURPOSE: Glioblastoma-associated macrophages are a major constituent of the immune response to therapy and are known to engulf the iron-based MR imaging contrast agent, ferumoxytol. Current ferumoxytol MR imaging techniques for localizing macrophages are confounded by contaminating intravascular signal. The aim of this study was to assess the utility of a newly developed MR imaging technique, segregation and extravascular localization of ferumoxytol imaging, for differentiating extravascular-from-intravascular ferumoxytol contrast signal at a delayed 24-hour imaging time point. MATERIALS AND METHODS: Twenty-three patients with suspected post-chemoradiotherapy glioblastoma progression underwent ferumoxytol-enhanced SWI. Segregation and extravascular localization of ferumoxytol imaging maps were generated as the voxelwise difference of the delayed (24 hours) from the early (immediately after administration) time point SWI maps. Continuous segregation and extravascular localization of ferumoxytol imaging map values were separated into positive and negative components. Image-guided biologic correlation was performed. RESULTS: Negative segregation and extravascular localization of ferumoxytol imaging values correlated with early and delayed time point SWI values, demonstrating that intravascular signal detected in the early time point persists into the delayed time point. Positive segregation and extravascular localization of ferumoxytol imaging values correlated only with delayed time point SWI values, suggesting successful detection of the newly developed extravascular signal. CONCLUSIONS: Segregation and extravascular localization of ferumoxytol MR imaging improves on current techniques by eliminating intrinsic tissue and intravascular ferumoxytol signal and may inform glioblastoma outcomes by serving as a more specific metric of macrophage content compared with uncorrected T1 and SWI techniques.

RESUMO

INTRODUCTION: Vascular calcification (VC) in hemodialysis (HD) patients is a sign of severe cardiovascular disease and can predict cardiovascular outcomes. Fetuin-A and osteopontin (OPN) inhibit VC. Serum fetuin-A levels are lower in patients with end-stage kidney disease (ESKD) and in those who are on chronic HD therapy. However, there are limited data concerning OPN in patients who are on dialysis. The aim of our study was to determine VC in HD patients, the relationship between VC and 25-OH-vitamin D, fetuin-A, and OPN levels, and independent predictors of VC. MATERIALS AND METHODS: Ninety-three patients with ESKD on HD therapy were recruited. Among these patients, 44 were male and 49 were female. The patient group was compared with a group of 20 healthy controls of similar age and sex. A plain radiograph of the hand was taken using a mammography machine for the evaluation of VC. Serum fetuin-A, OPN, and 25-OH-vitamin D levels of both patients and controls were measured. RESULTS: VC was detected in 45 (48.4%) HD patients. When patients were compared with healthy controls, fetuin-A levels (p < 0.029) were significantly lower in patients, whereas OPN (p < 0.000) and VC (p < 0.002) were significantly higher in the patient group. Age [odds ratio (OR) 1.036], the presence of diabetes mellitus (DM) (OR 17.527), and high parathyroid hormone (PTH) levels (OR 1.002) were independent predictors of VC in a logistic regression model including the following factors: age, the presence of DM, HD duration, and serum albumin, phosphate, PTH, 25-OH-vitamin D, fetuin-A, OPN, and calcium levels. No significant correlation was found between patients with VC and patients without VC in terms of fetuin-A, OPN, and 25-OH-vitamin D levels. CONCLUSIONS: VC is a frequent sign in patients undergoing HD and is not related to serum fetuin-A and osteopontin levels. Age, the presence of DM, and high PTH levels were independent predictors of VC in patients undergoing HD. Further studies are warranted to understand the mechanism underlying and the factors contributing to VC.

RESUMO

Similar to asbestos fibers, nonregulated mineral fibers can cause malignant mesothelioma (MM). Recently, increased proportions of women and young individuals with MM were identified in southern Nevada, suggesting that environmental exposure to carcinogenic fibers was causing the development of MM. Palygorskite, a fibrous silicate mineral with a history of possible carcinogenicity, is abundant in southern Nevada. In this study, our aim was to determine whether palygorskite was contributing to the development of MM in southern Nevada. While palygorskite, in vitro, displayed some cytotoxicity toward primary human mesothelial (HM) cells and reduced their viability, the effects were roughly half of those observed when using similar amounts of crocidolite asbestos. No Balb/c (0/19) or MexTAg (0/18) mice injected with palygorskite developed MM, while 3/16 Balb/c and 13/14 MexTAg mice injected with crocidolite did. Lack of MM development was associated with a decreased acute inflammatory response, as injection of palygorskite resulted in lower percentages of macrophages (p = .006) and neutrophils (p = .02) in the peritoneal cavity 3 d after exposure compared to injection of crocidolite. Additionally, compared to mice injected with crocidolite, palygorskite-injected mice had lower percentages of M2 (tumor-promoting) macrophages (p = .008) in their peritoneal cavities when exposed to fiber for several weeks. Our study indicates that palygorskite found in the environment in southern Nevada does not cause MM in mice, seemingly because palygorskite, in vivo, fails to elicit inflammation that is associated with MM development. Therefore, palygorskite is not a likely contributor to the MM cases observed in southern Nevada.

RESUMO

STUDY QUESTION: What is the success rate in terms of ovarian activity (menstrual cycles) as well as pregnancy and delivery rates 1 year after orthotopic ovarian transplantations conducted in a three-country network? SUMMARY ANSWER: In 49 women with a follow-up >1 year after transplantation, the ovaries were active in 67% of cases and the pregnancy and delivery rates were 33 and 25%, respectively. WHAT IS KNOWN ALREADY: Cryopreservation of ovarian tissue in advance of cytotoxic therapies and later transplantation of the tissue is being performed increasingly often, and the total success rates in terms of pregnancy and delivery have been described in case series. However, published case series have not allowed either a more detailed analysis of patients with premature ovarian insufficiency (POI) or calculation of success rates based on the parameter 'tissue activity'. STUDY DESIGN, SIZE, DURATION: Retrospective analysis of 95 orthotopic transplantations in 74 patients who had been treated for cancer, performed in the FertiPROTEKT network from 2008 to June 2015. Of those 95 transplantations, a first subgroup (Subgroup 1) was defined for further analysis, including 49 women with a follow-up period >1 year after transplantation. Of those 49 women, a second subgroup (Subgroup 5) was further analysed, including 40 women who were transplanted for the first time and who were diagnosed with POI before transplantation. PARTICIPANTS/MATERIALS, SETTING, METHODS: Transplantation was performed in 16 centres and data were transferred to the FertiPROTEKT registry. The transplantations were carried out after oncological treatment had been completed and after a remission period of at least 2 years. Tissue was transplanted orthotopically, either into or onto the residual ovaries or into a pelvic peritoneal pocket. The success rates were defined as tissue activity (menstrual cycles) after 1 year (primary outcome) and as pregnancies and deliveries achieved. MAIN RESULTS AND THE ROLE OF CHANCE: The average age of all transplanted 74 women was 31 ± 5.9 years at the time of cryopreservation and 35 ± 5.2 at the time of transplantation. Twenty-one pregnancies and 17 deliveries were recorded. In Subgroup 1, tissue was cryopreserved at the age of 30 ± 5.6 and transplanted at 34 ± 4.9 years. Ovaries remained active 1 year after transplantation in 67% of cases (n = 33/49), the pregnancy rate was 33% (n = 16/49) and the delivery rate was 25% (n = 12/49). In Subgroup 5, tissue was cryopreserved at the age 30 ± 5.9 years and transplanted at 34 ± 5.2 years. Ovaries remained active 1 year after transplantation in 63% of cases (n = 25/40), the pregnancy rate was 28% (n = 11/40) and the delivery rate was 23% (n = 9/40). The success rates were age dependant with higher success in women who cryopreserved at a younger age. In Subgroup 5, tissue was exclusively transplanted into the ovary in 10% (n = 4/40) of women and into a peritoneal pocket in 75% (n = 30/40), resulting in spontaneous conceptions in 91% of patients (n = 10/11). LIMITATIONS, REASONS FOR CAUTION: The data were drawn from a retrospective analysis. The cryopreservation and transplantation techniques used have changed during the study period. The tissue was stored in many tissue banks and many surgeons were involved, leading to heterogeneity of the procedures. However, this does reflect the realistic situation in many countries. Although patients with POI were evaluated before transplantation to allow specific analysis of the transplanted tissue itself, the possibility cannot be excluded that residual ovarian tissue was also reactivated. WIDER IMPLICATIONS OF THE FINDINGS: This is the largest case series worldwide to date and it confirms that cryopreservation and transplantation of ovarian tissue can be a successful option for preserving fertility. Persistent tissue activity 12 months after transplantation suggests that the pregnancy and delivery rates may increase further in the future. As transplantation into the peritoneum results in a high success rate, this approach may be an alternative to transplantation into the ovary. However, in order to establish the best transplantation site, a randomized study is required. STUDY FUNDING/COMPETING INTEREST: This study was in part funded from the Deutsche Forschungsgemeinschaft (# DI 1525) and the Wilhelm Sander Foundation (2012.127.1) and did not receive any funding from a commercial company.

RESUMO

On November 9 and 10, 2015, the International Conference on Mesothelioma in Populations Exposed to Naturally Occurring Asbestiform Fibers was held at the University of Hawaii Cancer Center in Honolulu, Hawaii. The meeting was cosponsored by the International Association for the Study of Lung Cancer, and the agenda was designed with significant input from staff at the U.S. National Cancer Institute and National Institute of Environmental Health Sciences. A multidisciplinary group of participants presented updates reflecting a range of disciplinary perspectives, including mineralogy, geology, epidemiology, toxicology, biochemistry, molecular biology, genetics, public health, and clinical oncology. The group identified knowledge gaps that are barriers to preventing and treating malignant mesothelioma (MM) and the required next steps to address barriers. This manuscript reports the group's efforts and focus on strategies to limit risk to the population and reduce the incidence of MM. Four main topics were explored: genetic risk, environmental exposure, biomarkers, and clinical interventions. Genetics plays a critical role in MM when the disease occurs in carriers of germline BRCA1 associated protein 1 mutations. Moreover, it appears likely that, in addition to BRCA1 associated protein 1, other yet unknown genetic variants may also influence the individual risk for development of MM, especially after exposure to asbestos and related mineral fibers. MM is an almost entirely preventable malignancy as it is most often caused by exposure to commercial asbestos or mineral fibers with asbestos-like health effects, such as erionite. In the past in North America and in Europe, the most prominent source of exposure was related to occupation. Present regulations have reduced occupational exposure in these countries; however, some people continue to be exposed to previously installed asbestos in older construction and other settings. Moreover, an increasing number of people are being exposed in rural areas that contain noncommercial asbestos, erionite, and other mineral fibers in soil or rock (termed naturally occurring asbestos [NOA]) and are being developed. Public health authorities, scientists, residents, and other affected groups must work together in the areas where exposure to asbestos, including NOA, has been documented in the environment to mitigate or reduce this exposure. Although a blood biomarker validated to be effective for use in screening and identifying MM at an early stage in asbestos/NOA-exposed populations is not currently available, novel biomarkers presented at the meeting, such as high mobility group box 1 and fibulin-3, are promising. There was general agreement that current treatment for MM, which is based on surgery and standard chemotherapy, has a modest effect on the overall survival (OS), which remains dismal. Additionally, although much needed novel therapeutic approaches for MM are being developed and explored in clinical trials, there is a critical need to invest in prevention research, in which there is a great opportunity to reduce the incidence and mortality from MM.

RESUMO

Introduction: Intraabdominal adhesions that develop because of prior abdominal or pelvic surgery may cause problems during surgery. Complications can include difficult intraabdominal entry; injury to the urinary bladder, uterus or small intestine; longer operation times, and increased blood loss. The goal of the present study was to evaluate the association between abdominal striae gravidarum and intraabdominal adhesions in the preoperative period in pregnant women with a history of cesarean section. Materials and Methods: The study included 247 pregnant women at ≥ 37 weeks of gestation admitted to the labor unit for delivery; all had undergone at least one previous cesarean section. Abdominal striae were assessed preoperatively using the Davey scoring system; the severity and intensity of adhesions were subsequently evaluated intraoperatively according to the modified Nair scoring system. Results: No striae were seen in 104 pregnant women; 41 had mild striae and 102 had severe striae. Overall, 113 cases had no adhesions (grade 0), 106 had grade 1-2 adhesions, and 28 had grade 3-4 adhesions. Among patients with grade 0 adhesions, 34 (13.7 %) had no striae, while 79 (31.9 %) had mild-to-severe striae (p < 0.001; sensitivity 55 %; specificity 67 %; positive predictive value 69 %; negative predictive value 52 %). Among women with grade 1-2 adhesions, 48 (19.4 %) had no striae, while 58 (23.4 %) had mild-to-severe striae. Finally, among women with grade 3-4 adhesions, 22 (8.9 %) had no striae, while 6 (2.4 %) had mild-to-severe striae (p < 0.001). A p-value < 0.05 was taken to indicate statistical significance. Conclusions: The abdominal adhesion score dropped as the abdominal striae gravidarum score rose during the preoperative period. Addition of this useful, easy-to-apply, inexpensive, adjunctive, observational, abdominal scoring method to the obstetrical work-up can provide important clues about the intraabdominal adhesion status of pregnant women scheduled for cesarean delivery because of previous cesarean section.

RESUMO

OBJECTIVE: Obesity is an important preventable cause of death and is a major risk factor for cardiovascular diseases as well as skeletal system diseases and malignancies. In many studies, complete blood count (CBC) and ratios derived from its results - such as the neutrophil/lymphocyte ratio, platelet/lymphocyte ratio and systemic immune inflammatory index have been associated with some diseases and their surveys. In these studies, the body mass index (BMI) and state of obesity of patients and the possible effects of these factors on CBC have not been defined. In this study, our aim was to evaluate the effect of BMI and smoking on CBC and ratios derived from CBC. PATIENTS AND METHODS: In this cross-sectional, retrospective study; the data of male and female patients aged between 18-65 years who presented for a routine check-up or obesity was collected and subjects were grouped as normal weight, overweight, obese and morbidly obese accordingly BMI. Persons' smoking habits were calculated as pack/years. All complete blood count results were noted. Smoking status and BMI groups were compared to CBC findings and ratios derived from these findings. RESULTS: After exclusion, 223 participants' data (104 female and 119 male) was included in the study. BMI was found to have a statistically significant positive linear correlation with lymphocyte number, PDW, SII and RDW (p < 0.05), and an extremely significant positive linear correlation (p < 0.01) was found between BMI and WBC, neutrophil count, PCT and platelet count. When BMI was not considered and 135 smokers were compared to 88 non-smokers, leukocytes and neutrophil counts were found to be higher in smokers (p < 0.05). CONCLUSIONS: Our study has found that WBC, neutrophil count, lymphocyte count, platelet count, PCT, PDW and SII are significantly affected by BMI status. Future studies that use these parameters and indices must take the participants' BMI and smoking status into account.

RESUMO

The ameliorative potential and antioxidant capacity of an extract of Urtica dioica seeds (UDS) was investigated using histopathological changes in liver and kidney, measuring serum marker enzymes, antioxidant defence systems and lipid peroxidation (malondialdehyde (MDA)) content in various tissues of broilers exposed to aflatoxin (AF). A total of 32 broilers were divided randomly into 4 groups: control, UDS extract-treated, AF-treated and AF+UDS extract-treated. Broilers in control and UDS extract-treated groups were fed on a diet without AF. The AF-treated group and AF+UDS extract-treated groups were treated with an estimated 1 mg total AF/kg feed. The AF+UDS extract groups received in addition 30 ml UDS extract/kg diet for 21 d. The AF-treated group had significantly decreased body weight gain when compared to the other groups. Biochemical analysis showed a small increase in the concentrations of serum aspartate aminotransferase, alanine aminotransferase, gamma glutamyl transpeptidase and lactate dehydrogenase in the AF-treated group compared to that of the control group, whereas concentrations of these enzymes were decreased in the AF+UDS group compared to that of the AF-treated group. Administration of supplementary UDS extract helped restore the AF-induced increase in MDA and reduced the antioxidant system towards normality, particularly in the liver, brain, kidney and heart. Hepatorenal protection by UDS extracts was further supported by the almost normal histology in AF+UDS extract-treated group as compared to the degenerative changes in the AF-treated broilers. It was concluded that UDS extract has a protective hepatorenal effect in broilers affected by aflatoxicosis, probably acting by promoting the antioxidative defence systems.

RESUMO

Waldenström's macroglobulinemia (WM) is a B-cell non-Hodgkin's lymphoma (B-NHL) characterized by immunoglobulin M (IgM) monoclonal gammopathy and the medullary expansion of clonal lymphoplasmacytic cells. Neoplastic transformation has been partially attributed to hyperactive MYD88 signaling, secondary to the MYD88 L265P mutation, occurring in the majority of WM patients. Nevertheless, the presence of chronic active B-cell receptor (BCR) signaling, a feature of multiple IgM+ B-NHL, remains a subject of speculation in WM. Here, we interrogated the BCR signaling capacity of primary WM cells by utilizing multiparametric phosphoflow cytometry and found heightened basal phosphorylation of BCR-related signaling proteins, and augmented phosphoresponses on surface IgM (sIgM) crosslinking, compared with normal B cells. In support of those findings we observed high sIgM expression and loss of phosphatase activity in WM cells, which could both lead to signaling potentiation in clonal cells. Finally, led by the high-signaling heterogeneity among WM samples, we generated patient-specific phosphosignatures, which subclassified patients into a 'high' and a 'healthy-like' signaling group, with the second corresponding to patients with a more indolent clinical phenotype. These findings support the presence of chronic active BCR signaling in WM while providing a link between differential BCR signaling utilization and distinct clinical WM subgroups.

RESUMO

BACKGROUND: Wolcott-Rallison syndrome is an autosomal recessive, multisystem disorder with onset of diabetes in the neonatal period or early infancy. CASE REPORT: A 9-year-old girl with diabetes and growth failure from 2 months of age presented with ketoacidosis and multiple organ failure. Evaluation for short stature revealed epiphyseal dysplasia. A homozygous mutation in the EIF2AK3 gene confirmed the clinical diagnosis of Wolcott-Rallison syndrome. She was euthyroid. Biochemical evaluation for potential adrenal dysfunction because of persistently elevated serum potassium (range 5.9-6.3 meq/l) and low serum sodium levels (range 128-130 meq/l) 2 weeks after resolution of ketoacidosis yielded normal findings with respect to basal corticotropin (31 pg/ml) and cortisol (18.7 µg/dl) levels. Estimated GFR-Schwartz (36.9 ml/min/1.73 m(2) ) was consistent with stage 3 chronic renal failure. The transtubular potassium gradient was 1.39 (normal value in hyperkalemic states: > 4.1). The plasma aldosterone (upright: 241.3 pmol/l) was within normal ranges, and plasma renin [39 pg/ml (range 5.41-34.53 pg/ml)] was slightly elevated. The patient was diagnosed as having relative hypoaldosteronism and was started on a sodium-rich diet and low potassium. Failure to respond to the dietary intervention prompted a trial of oral fludrocortisone with subsequent normalization of electrolyte levels. CONCLUSIONS: This is the first case report of Wolcott-Rallison syndrome complicated with relative hypoaldosteronism. Further research is needed to probe the causal inference of relative hypoaldosteronism with chronic renal failure in patients with Wolcott-Rallison syndrome.

RESUMO

The objective of this study was to evaluate the clinicopathological characteristics, treatment and prognosis of advanced endometrial cancer (EC). Patients who underwent surgery for advanced EC between January 1995 and December 2012 were retrospectively reviewed. Patients with missing data, concurrent cancers or uterine sarcomas and those who did not undergo surgery were excluded. The effects of clinicopathological factors on progression-free survival (PFS) and overall survival (OS) were analyzed. A total of 104 patients were included. Most presented with endometrioid histology (74%) and stage-III disease (87.5%), and 76.9% underwent optimal cytoreduction. A multivariate analysis confirmed that lymphovascular space invasion (LVSI) is an independent poor prognostic factor for PFS [odds ratio (OR): 21.37, p = 0.005] and OS [OR: 8.09, p = 0.044]. Suboptimal cytoreduction is another independent poor prognostic factor for PFS [OR: 5.68, p < 0.001]. Our study demonstrated that LVSI and optimal cytoreduction are the most significant factors affecting the survival of advanced EC patients.
