RESUMO

BACKGROUND: Women frequently complain of lower urinary tract symptoms (LUTS) during pregnancy due to multiple physiological and potentially pathological changes. Still, there is limited data on the characteristics of LUTS for pregnant women in Palestine. Therefore, this study was designed to assess LUTS among pregnant women in Palestine, in addition to identifying factors that exacerbate LUTS during pregnancy. METHODS: We devised a cross-sectional, questionnaire-based study that used the Urinary Distress Inventory (UDI) and the Incontinence Impact Questionnaire (IIQ) tools to assess LUTS during pregnancy in an antenatal care clinic setting. Multiple linear regressions were conducted to determine variables that significantly related to LUTS (UDI-6 and IIQ-7 scores as dependent variables). RESULTS: The study recruited 306 pregnant women. Regarding LUTS findings, the participants scored a mean of 31.9 ± 24.9 out of 100 points (6.7 ± 5.2 out of 21) for the IIQ-7 scale and a mean of 31.2 ± 19.2 out of 100 points (5.6 ± 3.4 out of 18) for the UDI-6 scale. Regression analysis showed that older women (p = 0.031), women with a higher body mass index (p < 0.001), and women in the third trimester of pregnancy (p = 0.023), were independently associated with high UDI score. Multiple linear regression analysis showed that obese and overweight patients (p = 0.006) and multiparity (p = 0.026) were independently associated with high IIQ score. CONCLUSIONS: High body mass index is independently associated with both UDI and IIQ scores for LUTS. Several strategies should be arranged to raise the awareness of females of childbearing age in Palestine regarding LUTS during pregnancy and factors which may exacerbate LUTS, such as obesity and multiparity. Thus, preventive measures should be implemented, such as serial assessment of LUTS during antenatal care to respond timely to this frequent problem.

RESUMO

BACKGROUND: Lower urinary tract symptoms (LUTS) are prevalent among pregnant women. Several articles show the impact of LUTS on pregnant women's quality of life (QoL). This study was designed to examine the impact of non-pathological LUTS on QoL among pregnant Palestinian women. METHODS: A cross-sectional, hospital-based study was conducted on women who were pregnant and receiving regular antenatal care at the obstetrics and gynecology clinic in Rafidia Hospital, Palestine. This self-administered questionnaire included the Urinary Distress Inventory - short-form (UDI-6), the Incontinence Impact Questionnaire - short-form (IIQ-7), the European Quality of Life scale - 5 dimensions (EQ-5D), and the European Quality of Life - visual analogue scale (EQ-VAS). A convenience sampling method was used. In addition to this, multiple linear regression analyses were performed aiming to identify variables that have a significant relationship with QoL (i.e. socio-demographic variables, UDI-6 score, and IIQ-7 score). RESULTS: This study included a total of 306 pregnant women. Participants had a mean age of 26.9 years (SD, 3.6). The subjects scored an average of 31.2 ± 19.2 out of 100 points for the UDI-6 scale and an average of 31.9 ± 24.9 out of 100 points for the IIQ-7 scale. On the other hand, the subjects' average EQ-5D and EQ-VAS scores were 0.76 ± 0.17 and 67.96 ± 19.28 respectively. The subjects' responses on UDI-6 significantly correlated with their responses on both the EQ-5D and EQ-VAS scales (r = - 0.338, p < 0.001 and r = - 0.206, p < 0.001, respectively). Likewise, their responses on IIQ-7 also significantly correlated with their responses on both the EQ-5D and EQ-VAS scales (r = - 0.389, p < 0.001 and r = - 0.329, p < 0.001, respectively). Regression analysis found that the UDI-6 score (p = 0.001) and IIQ-7 score (p < 0.001), were significantly and negatively associated with EQ-5D index scores. CONCLUSIONS: Our study shows a remarkable correlation between LUTS and QoL among pregnant women. Further longitudinal studies are required to assess the status of LUTS in the pre-pregnancy stage to ascertain a more accurate assessment of LUTS or LUTS related intervention and its impact on QoL during pregnancy.

RESUMO

We report the case of a 55-year-old-male with a large cell metastatic pancreatic neuroendocrine carcinoma treated for 14 months with lanreotide autogel having a stable disease (SD) and not responding to chemotherapy. The somatostatin analogues (SSA) were introduced after an episode of diarrhea and controlled the disease. Progression-free survival (PFS) as determined by Computerized Tomography (CT) scans was obtained for 14 months. After more than a year, the patient's health state deteriorated along with progressive disease. The capecitabine-temozolomide regimen was challenged, but after three cycles, a rapid clinical decline was noted. CONCLUSION: This unexpected event (diarrhea) in the course of the disease could represent the beginning of carcinoid syndrome. While the lanreotide autogel helped the episode of diarrhea pass, it also helped gain control over the disease itself.

RESUMO

CONTEXT: Pancreatic neuroendocrine tumours (PanNETs) are rare pancreatic neoplasms. PanNETs can be treated by multimodal approach including surgery, locoregional and systemic therapy. OBJECTIVE: The aim of the present study is to evaluate predictive factors of overall survival in patients with PanNETs surgically treated at a single center. SUBJECTS AND METHODS: The study group consisted of 120 patients with PanNETs who had undergone surgery at the Center of Digestive Diseases and Liver Transplantation of Fundeni Clinical Institute, Bucharest, Romania. Surgical resection of the primary tumor was performed in 110 patients. RESULTS: Tumor size > 2 cm (p=0.048) (90% CI) lymph node involvement (p=0.048), ENET grade (p<0.001), distant metastases (p<0.001), Ki 67 index (<2%, 2-5%, 5-10%, 10-20%, >20%) (p<0.001) were identified as significant prognostic factors for OS on univariate analysis. Using multivariate Cox proportional regression model we found that distant metastases and Ki 67 index were independent risk factors for the survival outcome. CONCLUSIONS: Surgery with curative intent should be considered in all cases if clinically appropriate and technically feasible. High grade (Ki67 index ≥10%) tumours were associated with a 2- fold increase in risk of death as compared to those with a Ki67 <10%.

RESUMO

There is no agreement on the involvement of angiotensin II type 1 receptor (AT1R) gene A(1166)C variant and essential hypertension. The purpose of this study was to investigate the association between angiotensin II type 1 receptor (AT1R) gene A(1166)C variants with essential hypertension and some related parameters in a sample of Jordanian hypertensive patients. DNA samples from 108 hypertensive individuals and 102 age- and gender-matched non-hypertensive controls of the Jordanian population were analyzed by polymerase chain reaction followed by restriction fragment length polymorphism assay (PCR-RFLP) methods to determine the frequency of A(1166)C variants alleles. No statistically significant differences were found in the distribution of alleles and genotypes between hypertensive and non-hypertensive individuals, not even after gender segregation. The frequency of the variant allele (C(1166)) was significantly higher in the early-onset compared to the late-onset group of hypertensive males, in subjects with positive family history of hypertension, and in subjects with high waist circumference. In conclusion, the A(1166)C polymorphism is not associated with essential hypertension in Jordanian hypertensive individuals. However, it was associated with an early onset of hypertension in males, with positive family history of hypertension, and with high waist circumference irrespective of blood pressure status.

RESUMO

The pancreas procurement from brain-dead donors used for pancreatic islet isolation and transplantation, was analyzed between 2007-2012. The pancreas was transported to the Fundeni Clinical Institute and the islet isolation process was performed in the Cell Therapy Laboratory. There were 20 en bloc pancreas-duodenum-spleen procurement during multiorgan harvesting. Eighteen pancreata were used for islet isolation and two were used for whole pancreas transplantation.One pancreas was used for whole pancreas transplant alone and the other one was used for simultaneous pancreas and kidney transplantation. Donor age ranged between 12 and 61 years, with a median age of 35 years old. The donors were 9 females and 11 males. The causes of death were in 8 cases ­brain injury, in 7 cases ­ aneurism rupture, and in 5 cases stroke. The donors' blood group was A(II) in 11 cases, O(I) in7 cases, and B(III) in 2 cases. The calculated BMI of the donors ranged between 15.6 and 27.8, with a median value of 24.1. The median calculated Vinkers score for our study group was 11. Cold ischemia time ranged between 1.5 and 8 hours,with a median value of 5 hours.

RESUMO

BACKGROUND: Tobacco use remains the leading cause of preventable disease, disability, and death in the world. Lebanon has an exceptionally high tobacco use burden. The World Health Organization endorses smoking cessation advice integrated into primary care settings as well as easily accessible and free phone-based counseling and low-cost pharmacotherapy as standard of practice for population-level tobacco dependence treatment. Although these interventions can increase access to tobacco treatment and are highly cost-effective compared with other interventions, their evidence base comes primarily from high-income countries, and they have rarely been evaluated in low- and middle-income countries. Recommended interventions are not integrated as a routine part of primary care in Lebanon, as in other low-resource settings. Addressing this evidence-to-practice gap requires research on multi-level interventions and contextual factors for implementing integrated, scalable, and sustainable cessation treatment within low-resource settings. METHODS: The objective of this study is to evaluate the comparative effectiveness of promising multi-component interventions for implementing evidence-based tobacco treatment in primary healthcare centers within the Lebanese National Primary Healthcare Network. We will adapt and tailor an existing in-person smoking cessation program to deliver phone-based counseling to smokers in Lebanon. We will then conduct a three-arm group-randomized trial of 1500 patients across 24 clinics comparing (1) ask about tobacco use; advise to quit; assist with brief counseling (AAA) as standard care; (2) ask; advise; connect to phone-based counseling (AAC); and (3) AAC + nicotine replacement therapy (NRT). We will also evaluate the implementation process to measure factors that influence implementation. Our central hypothesis is that connecting patients to phone-based counseling with NRT is the most effective alternative. This study will be guided by the Exploration, Preparation, Implementation, Sustainment (EPIS) framework, supported by Proctor's framework for implementation outcomes. DISCUSSION: The project addresses the evidence-to-practice gap in the provision of tobacco dependence treatment within low-resource settings by developing and testing contextually tailored multi-level interventions while optimizing implementation success and sustainability. This research is significant for its potential to guide the large-scale adoption of cost-effective strategies for implementing tobacco dependence treatment in low-resource settings, thereby reducing tobacco-related morbidity and mortality.

RESUMO

INTRODUCTION: Novel prevention programs are developed to address the increase in e-cigarette use (vaping) among children. However, it remains paramount to test their feasibility in rural settings. This pilot study implemented and evaluated the feasibility and outcomes of two innovative programs, CATCH My Breath and smokeSCREEN, among youth in rural settings in Florida. METHODS: We conducted four focus groups with youth aged 11-17 recruited from 4-H rural clubs in Florida. In a subsequent randomized trial, we recruited 82 youth participants and assigned them to one of three arms: CATCH My Breath, smokeSCREEN, or control. CATCH My Breath and smokeSCREEN participants attended online group intervention sessions while the control group received educational material. Pre- and post-surveys were administered to all participants to assess knowledge, susceptibility, perceived positive outcomes and risk perceptions related to tobacco and e-cigarette use. Other feasibility parameters were also assessed. RESULTS: Focus group discussions provided insights about feasibility and informed the implementation of both interventions in terms of delivery format, scheduling of sessions and incentives. After the intervention, CATCH My Breath participants significantly improved their general tobacco-related knowledge (post-pre = 16.21-12.92 = 3.3, p <.01) and risk perceptions towards other flavored tobacco products (post-pre = 19.29-17.71 = 1.6, p <.05). smokeSCREEN participants significantly improved their general tobacco knowledge (post-pre = 18.77-13.77 = 5.0, p <.01), knowledge about e-cigarettes (post-pre = 9.08-6.31 = 2.8, p <.01) and risk perception towards e-cigarettes (post-pre = 24.69-21.92 = 2.8, p <.05). CONCLUSIONS: This study demonstrated feasibility of delivering the interventions via participant engagement, participants' willingness to be randomized, assessment of outcome measures, and exploration of different recruitment methods. Despite the potential positive influence of CATCH My Breath and smokeSCREEN on youth participants, further evaluation with larger samples is needed.

RESUMO

The study aimed to evaluate the antimicrobial activity of 0.5 or 1% (w/w) chitosan and 1% (w/w) garlic against Salmonella spp., Escherichia coli O157:H7 and Listeria monocytogenes in hummus dip stored at 4, 10, or 25°C for 28, 21, or 7 days, respectively. In hummus without garlic, at all storage temperatures and storage periods, 0.5% chitosan decreased Salmonella spp., E. coli O157:H7, and L. monocytogenes by 0.9-2.3, 0.6-2.3, and 0.9-1.3 log CFU/g, respectively. In comparison, 1% chitosan decreased the numbers by 1.6-2.9, 1.4-2.7, and 1.3-1.8 log CFU/g, respectively. In hummus with 1% garlic, 0.5% chitosan decreased Salmonella spp., E. coli O157:H7, and L. monocytogenes by 0.7-2.5, 0.6-2.2, and 1.0-1.5 log CFU/g, respectively. Furthermore, 1% chitosan decreased the numbers by 1.6-2.8, 1.2-2.7, and 1.5-1.6 log CFU/g, respectively. With few exceptions, adding 1% garlic to hummus did not result in any significant reduction (at p < 0.05) in microbial numbers. The greatest decreases of Salmonella spp., E. coli O157:H7, and L. monocytogenes were 3.1, 3.6, and 2.9 log CFU/g with 1% chitosan held at 4°C for 28 days. The highest overall acceptability was for hummus with 0.5% chitosan + 1% garlic. Commercial use of chitosan is expected to help producers improve hummus safety. PRACTICAL APPLICATION: Hummus is consumed worldwide as a dip due to its taste and health benefits. Microbial safety of hummus can be enhanced by incorporating chitosan, derived from the natural polymer chitin, into the formulation. This enhanced recipe would be a bonus for producers and consumers alike.

RESUMO

Neuroendocrine tumors, known as carcinoid tumors constitute a heterogeneous group of neoplasms that present many clinical challenges. They secrete peptides and neuroamines that cause specific clinical syndromes. Assessment of specific or general tumors markers offers high sensitivity in establishing the diagnosis and they also have prognostic significance. Management strategies include curative surgery, whenever possible-that can be rarely achieved, palliative surgery, chemotherapy, radiologic therapy, such as radiofrequency ablation and chemoembolisations and somatostatin analogues therapy in order to control the symptoms. The aim of this paper is to review recent publications in this field and to give recommendations that take into account current advances in order to facilitate improvement in management and outcome.

RESUMO

An important objective in nowadays research is the discovery of new biomarkers that can detect colon tumours in early stages and indicate with accuracy the status of the disease. The aim of our study was to identify potential biomarkers for colon cancer onset and progression. We assessed gene expression profiles of a list of 10 candidate genes (MMP-1, MMP-3, MMP-7, DEFA 1, DEFA-5, DEFA-6, IL-8, CXCL-1, SPP-1, CTHRC-1) by quantitative real time PCR in triplets of colonic mucosa (normal, adenoma, tumoral tissue) collected from the same patient during surgery for a group of 20 patients. Additionally we performed immunohistochemistry for DEFA1-3 and SPP1. We remarked that DEFA5 and DEFA6 are key factors in adenoma formation (p<0.05). MMP7 is important in the transition from a benign to a malignant status (p <0.01) and further in metastasis being a prognostic indicator for tumor transformation and for the metastatic potential of cancer cells. IL8, irrespective of tumor stage, has a high mRNA level in adenocarcinoma (p< 0.05). The level of expression for SPP1 is correlated with tumor level. We suggest that high levels of DEFAS, DEFA6 (key elements in adenoma formation), MMP7 (marker of colon cancer onset and progression to metastasis), SPP1 (marker of progression) and IL8 could be used to diagnose an early stage colon cancer and to evaluate the prognostic of progression for colon tumors. Further, if DEFA5 and DEFA6 level of expression are low but MMP7, SPP1 and IL8 level are high we could point out that the transition from adenoma to adenocarcinoma had already occurred. Thus, DEFA5, DEFA6, MMP7, IL8 and SPP1 consist in a valuable panel of biomarkers, whose detection can be used in early detection and progressive disease and also in prognostic of colon cancer.

RESUMO

BACKGROUND: Operative treatment of chronic pancreatitis is indicated for patients with intractable pain after failed medical and endoscopic treatment, or in the presence of complications of the disease. AIMS: This study evaluates a single-center experience with operative management of chronic pancreatitis over a period of time of 14 years, regarding indication, surgical technique, early and late results. PATIENTS AND METHODS: The records of 265 consecutive patients who underwent surgery for chronic pancreatitis between 1995 and 2008 were retrospectively reviewed and analyzed. Long-term outcomes were assessed by patient survey, with a median follow-up of 40 months. RESULTS: 265 patients underwent 275 operations for chronic pancreatitis with the main indication abdominal pain (46.8%), followed by suspected malignancy in 24.8% and recurrent episodes of acute pancreatitis in 18.6%. Resection procedures 54.5% (150), drainage procedures 1.09% (3), bypass and denervation procedures 44.36% (122) and exploratory laparotomy 3.27% (9) were performed with an overall morbidity of 22% and an in-hospital mortality rate of 2.64%. After a median follow-up of 40 months survival information was available for 137 patients (51.69%) with a 5-and actuarial survival rate of 74.7% and quality of life improvement in most patients, especially in the resected group. CONCLUSION: Our results suggest that in chronic pancreatitis the type of surgery has to be individualized in each patient (resection VS drainage) and organ preserving operations are safe and effective in providing long-term pain relief and in treating CP-related complications

RESUMO

This study describes an experimental model of accessory renal allotransplantation in the big laboratory animal (pig). A total of 24 common-breed pigs were used. All allografts were transplanted in an accessory manner and revascularized at the level of the infrarenal abdominal aorta and inferior vena cava. The urinary drainage was performed either through a nexternal uretheroneostomy at the ipsilateral lumbar region (Group A--n=8) or by internal uretheroneocystostomy (Group B--n=8). All transplants were monitored for 8 days postoperatively using translumbar ultrasound-guided biopsies at 1, 4, 7 days. A total of 16 transplants were performed. 1 ectopic donor kidney was found and transplanted in the same fashion. Mean operative time was 125 minutes, immediate postoperative survival was 100% and at 72 hours, 87.5%. The onset of acute rejection was at day 4, by massive lymphocyte infiltration and was directly correlated with the abrupt decrease of the allograft diuresis in Group A, at day 3. At day 7, the rejection was complete. Both methods of urinary drainage are functional and can be employed. This experimental model is a useful tool for training of the transplant surgeons or for transplantation research. The surgical technique for accessory renal allotransplantation in pig is easy to learn and offers the possibility for allograft monitoring until complete rejection without influencing the receptor health condition.

RESUMO

Subtotal pancreatectomy is an exceptional solution for the pain in chronic pancreatitis affecting the whole pancreas, which evolves with non-dilated Wirsung duct or in cases in which drainage procedures fail to achieve improvement of symptoms. If it is possible to avoid splenectomy, this type of surgical procedure enters in the modern concept of treatment of chronic pancreatitis named "organ sparing", basically being a Beger procedure combined with a distal pancreatectomy with spleen preservation. The case reported here is of a young male (29 years old) with idiopathic chronic pancreatitis progressively affecting the whole pancreas which had the main symptom the resistant pain to medical and non-resectional surgical treatment (left thoracoscopic splanchnicectomy at 4 years after diagnosis); at 8 years after diagnosis the pain becomes almost permanent, a cystic tumor is evolving in the body of pancreas and CA 19-9 tumor marker reaches values over 100 U/mL. In this context it was decided to perform a spleen-preserving subtotal pancreatectomy 95% (near total pancreatectomy) as the last therapeutic resource. The postoperative course was complicated with a biliary leak treated conservative and the patient was discharged in the 54th postoperative day. After 12 months the results are good regarding pain control, serum glucose levels and quality of life.

RESUMO

Stem cells therapies represent a new field of biomedical science which could provide in the future the cure for diseases until now incurable. The present paper reviews current knowledge on key biological properties of stem cells with focus on hepatic and gastrointestinal stem cells and current applications of stem cells therapies in gastrointestinal and liver diseases. Potential clinical applications for stem cells therapies have been suggested from animal model trials in acute liver failure, inherited metabolic liver disease and endstage liver disease (cirrhosis). Hematopoietic autologous stem cells transplantation has already been successfully performed in patients with severe inflammatory bowel disease or patients with refractory celiac disease with aberrant T cells. Future stem cells therapies for gastrointestinal postoperative or Crohn's disease fistulas are currently under investigation. More research is needed for perfecting stem cells harvesting protocols from different sources, in vitro expansion and differentiation protocols which can be used in phase II and III clinical trials.

RESUMO

Liver hydatid disease still represents a frequent condition in Romania, especially among population of Dobrogea County, which may lead to life-threatening complications. To assess the role of intraoperative ultrasound (IOUS) in the diagnosis and treatment algorithms of liver hydatid disease. We could not find any similar studies in the literature in order to compare the results. The paper represents a retrospective study of IOUS performed for liver hydatid disease on a group of 43 patients admitted in the 2nd Clinic of Surgery - Clinical Emergency Hospital of Constanta. IOUS was intraabdominal (36 cases), transdiaphragmatic (7 cases) and was able to diagnose infected liver HC (7 cases), locate bilio-cystic fistulas (6 cases), hydatic cysts (18 cases) or relation with important anatomic elements (12). Ultrasound-guided frenotomy was performed in 5 cases and ultrasound-guided puncture in 9 cases. In 26 out of 43 patients (60.47%), IOUS influenced decision making during surgery. These data recommends IOUS in managing hydatid disease, allowing a complete diagnosis and optimal treatment, thus reducing postoperative morbidity.

RESUMO

Rabbit and mouse IgG treated with glutaraldehyde (GA) were immunogenic in homologous species. Glutaraldehyde treatment induced in the IgG molecule two types of antigenic determinants. One of them was found on the monomeric fraction of GA-treated rabbit IgG (haptenic determinant) and the other on the polymeric fraction (structural determinant). The haptenic determinants were found also on monoaldehyde-treated rabbit IgG and GA-treated Fab and Fc fragments. It was demonstrated that rabbit and mouse antibodies are specific for GA-treated IgG and have species specificity. While GA treatment did not alter the antigen binding capacity of rabbit IgG antibody, its effector functions (except protein A binding) were much affected. Thus it was found that GA treatment enhances IgG ability to react with rheumatoid factor, reduces drastically its capacity to activate the complement system, abolishes the cytophilic properties of IgG and accelerates its catabolic rate. The possible blocking effect of GA on the amino acid residues (mainly Lys) situated in or very close to the effector sites of the IgG molecule is suggested.
