The physiological quality of Vigna unguiculata L. seeds shows tolerance to salinity.

Salinity reduces feijão-caupi production, and the search for tolerant varieties becomes important within the agricultural context, as, in addition to being used in the field, they can be used in genetic improvement. The objective was to for a identify variety that is tolerant to salinity considering the physiological quality of seeds and seedling growth. A 2 × 4 factorial scheme was used, referring to the varieties Pingo-de-ouro and Coruja, and four electrical conductivities of water (0; 3.3; 6.6 and 9.9 dS m-1). The physiological quality of seeds and the growth of seedlings were analyzed, in addition to the cumulative germination. The Pingo-de-ouro variety showed no germination, length of the shoot and root, dry mass of the shoot and root compromised up to electrical conductivity of 6 dS m-1 in relation to 0.0 dS m-1. On the other hand, the Coruja variety showed reduced germination, increased shoot and root length. The creole variety Pingo-de-ouro proved to be tolerant to salinity.

Radiographic evaluation of the bicipital groove morphology does not predict intraarticular changes in the long head of biceps tendon.

INTRODUCTION AND OBJECTIVES: This study aimed to examine the clinical utility of the radiographic evaluation of the bicipital groove in predicting long head of biceps tendon (LHBT) pathology. MATERIAL AND METHODS: A prospective study was conducted, and sixty consecutive patients proposed to shoulder arthroscopic surgery were selected. Before surgery, a radiographic evaluation was performed with a supine and a Fisk radiograph. Most supine radiographs (>75%) were non-interpretable and were excluded from the study. As some Fisk radiographs (26.7%) were also non-interpretable, that left 44 interpretable radiographs in the study. These were measured for medial opening angle, total opening angle, width and depth of the bicipital groove. The radiographic measurements and the presence of LHBT pathology, as assessed at arthroscopy, were correlated. RESULTS: Radiographic evaluation of the bicipital groove showed a mean medial opening angle of 53 ±â€¯15° (23-90), a mean total opening angle of 80 ±â€¯26° (30-135), a mean width of 10.3 ±â€¯2.5 mm (6-19) and a mean depth of 4.1 ±â€¯1.5 mm (1-8). Men had higher medial opening angle (60 vs 50°, p = 0.044) and wider grooves (11.9 vs 9.7 mm, p = 0.019). Twenty-five patients (56.8%) were found to have an abnormal LHBT. No correlation was found between the radiographic measurements and LHBT pathology. Only age was correlated with a LHBT lesion (61.8 vs 46.3 years, p < 0.001). CONCLUSIONS: Our results show that there is no correlation between radiographic morphologic evaluation of the bicipital groove and LHBT pathology.

Eficacia y seguridad de la ureteroscopia y la cirugía retrógrada intrarrenal sin fluoroscopia para el tratamiento de la urolitiasis: estudio comparativo / Efficacy and safety of fluoroless ureteroscopy and retrograde intrarenal surgery for the treatment of urolithiasis: A comparative study

Introducción Las técnicas convencionales de ureteroscopia (URS) y cirugía retrógrada intrarrenal (CRIR) requieren el uso de guía fluoroscópica, pero los riesgos derivados de la exposición a radiaciones ionizantes constituyen un motivo de preocupación entre pacientes y urólogos. El objetivo de este estudio fue evaluar la eficacia y la seguridad de la URS y la CRIR sin fluoroscopia y compararlas con los procedimientos convencionales guiados por fluoroscopia para el tratamiento de litiasis ureterales y renales. Material y métodos Los pacientes tratados con URS o CRIR para litiasis urinaria entre agosto de 2018 y diciembre de 2019 fueron evaluados retrospectivamente y agrupados según el uso de o la ausencia de fluoroscopia. Los datos se recopilaron de las historias individuales de los pacientes. Los criterios de valoración principales fueron la tasa libre de cálculos (TLC) y las complicaciones, comparadas entre los grupos con fluoroscopia y sin fluoroscopia. Se realizó un análisis de subgrupos por tipo de procedimiento (URS y CRIR) y un análisis multivariante para identificar los factores predictivos de litiasis residual. Resultados Un total de 231 pacientes cumplieron los criterios de inclusión: 120 (51,9%) en el grupo tratado con fluoroscopia convencional y 111 (48,1%) en el grupo tratado sin fluoroscopia. No se hallaron diferencias significativas entre los grupos en cuanto a la TLC (82,5% vs. 90,1%; p=0,127) o de complicaciones postoperatorias (35,0% vs. 31,5%; p=0,675). No se hallaron diferencias significativas entre estas variables en el análisis de subgrupos, independientemente del procedimiento considerado (AU)

Introduction Ureteroscopy (URS) and retrograde intrarenal surgery (RIRS) are traditionally guided by fluoroscopy, but the risks of exposure to ionizing radiation may present a matter of concern for patients and urologists. The aim of this study was to evaluate the efficacy and safety of fluoroless URS and RIRS compared with conventional fluoroscopy-guided procedures for the treatment of ureteral and renal stones. Material and methods Patients treated with URS or RIRS for urolithiasis between August 2018 and December 2019 were retrospectively evaluated and grouped according to the use of fluoroscopy. Data was collected from individual patient records. The main outcomes were stone-free rate (SFR) and complications, compared between the fluoroscopy and fluoroless groups. A subgroup analysis by type of procedure (URS and RIRS) and a multivariate analysis to identify predictors of residual stones were conducted. Results A total of 231 patients met the inclusion criteria: 120 (51.9%) in the conventional fluoroscopy group and 111 (48.1%) in the fluoroless group. No significant differences were found between groups regarding SFR (82.5% vs 90.1%; P=.127) or postoperative complication rate (35.0% vs 31.5%; P=.675). In the subgroup analysis these variables did not present significant differences, regardless of the procedure considered. In the multivariate analysis the fluoroless technique was not an independent predictor of residual lithiasis (OR: 0.991; 95%IC: 0.407-2.411; P=.983), when adjusted for procedure type, stone size and stone number. Conclusion URS and RIRS can be done without fluoroscopic guidance in selected cases, without affecting the efficacy or safety of the procedure (AU)

Metabarcoding Used for the First Time to Identify Prey of Wild Totoaba macdonaldi.

Totoaba macdonaldi is an endangered endemic fish of the Gulf of California. Overexploitation resulted in the Mexican government banning the fishing of this species in 1975, and it being listed as endangered. However, the species is still subject to illegal fishing. Despite its conservation status, little is known about totoaba biology. The present study aimed to implement, for the first time, a metabarcoding protocol to describe the totoaba diet. Four wild totoaba individuals, seized by Mexican law enforcement agents, were dissected, and their stomach contents were collected. Three representative amplicon libraries were generated for cephalopods, chordates, and eukaryotes. After sequencing, 18 different taxa were identified, of which 11 species were recognized as prey. The totoaba were found to have consumed Pacific anchovy (Cetengraulis mysticetus), flathead grey mullet (Mugil cephalus), bigeye croaker (Micropogonias megalops), northern anchovy (Engraulis mordax), ocean whitefish (Caulolatilus princeps), milkfish (Chanos chanos), and Pacific sardine (Sardinops sagax). Members of the Euphausiidae family (krill) were also identified. This study identified up to four times more species in much fewer samples than previous studies based on morphological recognition, thus confirming metabarcoding as an effective method for studying the feeding habits of this species and one providing the tools required for further analysis of the totoaba diet.

Age as a primary driver of the gut microbial composition and function in wild harbor seals.

Dietary changes are the major variation cause in the composition of the gut microbiota. The short lactation phase in phocids provides an exceptional opportunity to explore the microbiota's response to a quick transition from a milk-based to a solid diet. We investigated the effects of age and sex on the gut microbiota of harbor seals in Mexico using rectal and fecal samples from pups and adults. 16S gene sequencing revealed age explains most of the observed variations in microbial composition. Individuals with frequent contact (pups-female adults) have major microbial similarities than those with little or no contact (pups-male adults). Overall, adults and females (regardless of sex and age, respectively) have a greater microbial richness; as seals grow, the core microbiome shrinks, and microbial diversity increases. We found pathways related to milk and chitin digestion in pups' microbiomes, indicating pups were transitioning to a solid diet. An enrichment of routes related to dramatic weight loss and body mass indicated higher metabolic stress in pups in late breeding season, when they are weaned and start intermittent fasting. Our findings highlight the host-microbiome interaction in harbor seals during late breeding season in response to food shifts and metabolic stress.

Beneficial effects of whole-body vibration exercise for brain disorders in experimental studies with animal models: a systematic review.

Brain disorders have been a health challenge and is increasing over the years. Early diagnosis and interventions are considered essential strategies to treat patients at risk of brain disease. Physical exercise has shown to be beneficial for patients with brain diseases. A type of exercise intervention known as whole-body vibration (WBV) exercise gained increasing interest. During WBV, mechanical vibrations, produced by a vibrating platform are transmitted, to the body. The purpose of the current review was to summarize the effects of WBV exercise on brain function and behavior in experimental studies with animal models. Searches were performed in EMBASE, PubMed, Scopus and Web of Science including publications from 1960 to July 2021, using the keywords "whole body vibration" AND (animal or mice or mouse or rat or rodent). From 1284 hits, 20 papers were selected. Rats were the main animal model used (75%) followed by mice (20%) and porcine model (5%), 16 studies used males species and 4 females. The risk of bias, accessed with the SYRCLE Risk of Bias tool, indicated that none of the studies fulfilled all methodological criteria, resulting in possible bias. Despite heterogeneity, the results suggest beneficial effects of WBV exercise on brain functioning, mainly related to motor performance, coordination, behavioral control, neuronal plasticity and synapse function. In conclusion, the findings observed in animal studies justifies continued clinical research regarding the effectiveness and potential of WBV for the treatment of various types of brain disorders such as trauma, developmental disorders, neurogenetic diseases and other neurological diseases.

Human-edible protein contribution of tropical beef cattle production systems at different levels of intensification.

Sustainable intensification of tropical grasslands has been identified by researchers and stakeholders as a solution to decrease greenhouse gas emissions and deforestation. However, there are concerns about food security and the role of livestock in feed-food competition between animals and humans involving land and other resources. We aimed to determine the net protein contribution (NPC), a feed-food competitiveness index, of tropical beef cattle raised on extensive systems or finished in pastures or conventional feedlots, under different levels of intensification. We modelled five scenarios, from cow-calf to slaughter, based on common beef cattle practices in Brazil, whose main production system is grazing. Scenario 1 represented the lowest level of intensification and the most extensive system. Scenario 2 represented a moderately extensive system. Scenarios 3, 4, and 5 represented different degrees and practices of intensification, with animals in cow-calf and stocker phases raised solely on well-managed permanent pastures. In Scenario 3, the animals were finished in a feedlot. In Scenarios 4 and 5, all animals in the stocker phase received a protein-energy supplement, but in Scenario 4, animals were finished in a permanent pasture with high-concentrate intake. In Scenario 5, animals were finished in a feedlot. The human-edible protein (heP) conversion efficiency (hePCE) was calculated as the ratio of heP produced (meat) to heP consumed as feed, and the NPC was the product of hePCE using the protein quality ratio, accounting for the digestible indispensable amino acid score content. An hePCE > 1 indicated that meat production did not compete with humans for food, and an NPC > 1 indicated that it contributed positively to meet human requirements. Meat production and heP intake consistently increased with intensification. The greatest hePCE values were from Scenarios 1 (9.2), 2 (2.2), and 3 (1.2), which were essentially pasture-fed systems, compared to Scenarios 4 and 5 (average of 1.0). The NPC varied from 24.1 (Scenario 1) to 2.6 (Scenario 5). The area required to produce 1 kg of carcass decreased from 147 to 45 m2, and the slaughter age decreased from 36 to 21 months from the most extensive to intensive systems. Brazilian beef cattle production contributes positively to the protein requirements of humans without limiting human food supplies. The intensification of tropical grazing beef systems is a key strategy to save land and produce more meat without limiting food for humans, playing an important role in the food security agenda.

Transdiagnostic symptom dynamics during psychotherapy.

Psychotherapy is an effective treatment for many common mental health problems, but the mechanisms of action and processes of change are unclear, perhaps driven by the focus on a single diagnosis which does not reflect the heterogeneous symptom experiences of many patients. The objective of this study was to better understand therapeutic change, by illustrating how symptoms evolve and interact during psychotherapy. Data from 113,608 patients from psychological therapy services who completed depression and anxiety symptom measures across three to six therapy sessions were analysed. A panel graphical vector-autoregression model was estimated in a model development sample (N = 68,165) and generalizability was tested in a confirmatory model, fitted to a separate (hold-out) sample of patients (N = 45,443). The model displayed an excellent fit and replicated in the confirmatory holdout sample. First, we found that nearly all symptoms were statistically related to each other (i.e. dense connectivity), indicating that no one symptom or association drives change. Second, the structure of symptom interrelations which emerged did not change across sessions. These findings provide a dynamic view of the process of symptom change during psychotherapy and give rise to several causal hypotheses relating to structure, mechanism, and process.

An abrupt increase in foliage ABA levels on incipient leaf death occurs across vascular plants.

Forest mortality during drought has been attributed to hydraulic failure, which can be challenging to measure. A limited number of alternative proxies for incipient leaf death exist. Here we investigate whether a terminal increase in abscisic acid (ABA) levels in leaves occurs across vascular land plants and is an indicator of imminent leaf death. For different species across vascular plants, we monitored ABA levels during lethal drought as well as leaf embolism resistance, across the canopy as leaves die following senescence, or when leaves are exposed to a heavy, lethal frost late in the growing season. We observed a considerable increase in foliage ABA levels once leaves showed signs of incipient leaf death. This increase in ABA levels upon incipient leaf death, could be induced by embolism during drought, by freezing or as leaves age naturally, and was observed in species spanning the phylogeny of vascular land plants as well as in an ABA biosynthetic mutant plant. A considerable increase in foliage ABA levels may act as an indicator of impending leaf death.

Paper-Based Biosensors for COVID-19: A Review of Innovative Tools for Controlling the Pandemic.

The appearance and quick spread of the new severe acute respiratory syndrome coronavirus disease, COVID-19, brought major societal challenges. Importantly, suitable medical diagnosis procedures and smooth clinical management of the disease are an emergent need, which must be anchored on novel diagnostic methods and devices. Novel molecular diagnostic tools relying on nucleic acid amplification testing have emerged globally and are the current gold standard in COVID-19 diagnosis. However, the need for widespread testing methodologies for fast, effective testing in multiple epidemiological scenarios remains a crucial step in the fight against the COVID-19 pandemic. Biosensors have previously shown the potential for cost-effective and accessible diagnostics, finding applications in settings where conventional, laboratorial techniques may not be readily employed. Paper- and cellulose-based biosensors can be particularly relevant in pandemic times, for the renewability, possibility of mass production with sustainable methodologies, and safe environmental disposal. In this review, paper-based devices and platforms targeting SARS-CoV-2 are showcased and discussed, as a means to achieve quick and low-cost PoC diagnosis, including detection methodologies for viral genomic material, viral antigen detection, and serological antibody testing. Devices targeting inflammatory markers relevant for COVID-19 are also discussed, as fast, reliable bedside diagnostic tools for patient treatment and follow-up.

Relapsing polychondritis associated with heart block.

OBJECTIVE: The present article aims at describing a rare case of an RP patient who evolved with heart block and was successfully treated with corticoid pulse therapy, without the need for pacemaker insertion. PATIENTS AND METHODS: A systematic research on relapsing polychondritis (RP) and heart block (HB) published in PubMed/MEDLINE, Web of Sciences, LILACS, and Scielo from 1966 to August 2020 was performed. RESULTS: It was found 10 studies on RP associated with HB, and we added a case. Most were male (7/10) with ages 30 to 66 years old. RP disease duration was 1 week-6 years. In most cases (7/10), the RP was active when the HB occurred. A complete HB was observed in 4/7, followed by type II degree block in 3/7, and one patient had a sinus node dysfunction. Most patients received glucocorticoids. A pacemaker was inserted in 4/9 cases. Good outcome was observed in 3/9 patients and mortality in 2/10. CONCLUSIONS: We report the first case of an RP patient who had a heart block and was successfully treated with methylprednisolone pulse therapy. The authors suggest that in these RP cases, an attempt with a glucocorticoid pulse therapy may be offered to treat the heart block and prevent the insertion of a pacemaker.

Effects of supplementation with corn distillers' dried grains on animal performance, nitrogen balance, and enteric CH4 emissions of young Nellore bulls fed a high-tropical forage diet.

The inclusion of corn-dried distillers' grains (DDG) could be an alternative supplement to increase animal performance, nitrogen efficiency usage (NEU), and decrease enteric methane (CH4) emissions. Our goal was to determine whether DDG could replace a traditional supplement (cottonseed meal) without affecting animal performance, N balance, and CH4 emissions. The experiment was conducted during the forage growing season (December to April), with 15 d adaptation, and a 112 d experimental period. The experimental design was completely randomized with four treatments: a mineral supplement (MS), cottonseed meal supplement (CS), 50% replacement of CS by DDG (50DDG), and 100% replacement of CS by DDG (100DDG). Cottonseed meal and DDG were used as protein supplement. A total of 12 paddocks, 3 per treatment, were used to measure forage mass: morphological and chemical composition of forage, forage allowance, and animal performance. Six animals per treatment were used to evaluate DM intake, digestibility, CH4 emissions, microbial protein production (MCP), and NEU of each treatment. Eighty-one Young Nellore bulls (48 testers, 12 per treatments and 33 adjusters) with initial BW of 255 ±â€¯5 kg (10-12 months old) were supplemented with each supplement type at a level of 0.3% of BW. Pasture management was continuous stocking with a variable stocking rate (put-and-take). Enteric CH4 was measured using the gas tracer technique. The MCP was quantified using purine derivatives and the NEU mass balance. No differences were found in nutrient intake (P > 0.228). Individual animal performance and gain per area were higher in the treatments with concentrates compared with that of MS; however, there was no difference among treatments CS, 50DDG, and 100DDG. The ADG was 0.83 for MS and 1.08 kg/animal/d when supplemented (P < 0.05). Gain per hectare was 709 kg/ha for MS and 915 kg/ha when supplemented with concentrates (P < 0.05). There was no difference in CH4 production among treatments that average 180 g/animal/d; however, CH4 per kg of gain was reduced with CS. The CH4 conversion factor averaged 5.91%. There was no difference in the synthesis of MCP and NEU. Corn DDG can replace 100% of cottonseed meal as a protein source for supplementation of young Nellore bulls grazing in tropical pastures without affecting animal performance, NEU, MCP, and CH4 emissions.

Clinical, Imaging, and Lab Correlates of Severe COVID-19 Leukoencephalopathy.

BACKGROUND AND PURPOSE: Patients infected with the Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2) can develop a spectrum of neurological disorders, including a leukoencephalopathy of variable severity. Our aim was to characterize imaging, lab, and clinical correlates of severe coronavirus disease 2019 (COVID-19) leukoencephalopathy, which may provide insight into the SARS-CoV-2 pathophysiology. MATERIALS AND METHODS: Twenty-seven consecutive patients positive for SARS-CoV-2 who had brain MR imaging following intensive care unit admission were included. Seven (7/27, 26%) developed an unusual pattern of "leukoencephalopathy with reduced diffusivity" on diffusion-weighted MR imaging. The remaining patients did not exhibit this pattern. Clinical and laboratory indices, as well as neuroimaging findings, were compared between groups. RESULTS: The reduced-diffusivity group had a significantly higher body mass index (36 versus 28 kg/m2, P < .01). Patients with reduced diffusivity trended toward more frequent acute renal failure (7/7, 100% versus 9/20, 45%; P = .06) and lower estimated glomerular filtration rate values (49 versus 85 mL/min; P = .06) at the time of MRI. Patients with reduced diffusivity also showed lesser mean values of the lowest hemoglobin levels (8.1 versus 10.2 g/dL, P < .05) and higher serum sodium levels (147 versus 139 mmol/L, P = .04) within 24 hours before MR imaging. The reduced-diffusivity group showed a striking and highly reproducible distribution of confluent, predominantly symmetric, supratentorial, and middle cerebellar peduncular white matter lesions (P < .001). CONCLUSIONS: Our findings highlight notable correlations between severe COVID-19 leukoencephalopathy with reduced diffusivity and obesity, acute renal failure, mild hypernatremia, anemia, and an unusual brain MR imaging white matter lesion distribution pattern. Together, these observations may shed light on possible SARS-CoV-2 pathophysiologic mechanisms associated with leukoencephalopathy, including borderzone ischemic changes, electrolyte transport disturbances, and silent hypoxia in the setting of the known cytokine storm syndrome that accompanies severe COVID-19.

Radiographic evaluation of the bicipital groove morphology does not predict intraarticular changes in the long head of biceps tendon. / La evaluación radiográfica de la morfología del surco intertubercular no pronostica cambios intraarticulares en el tendón de la porción larga del bíceps.

INTRODUCTION AND OBJECTIVES: This study aimed to examine the clinical utility of the radiographic evaluation of the bicipital groove in predicting long head of biceps tendon (LHBT) pathology. MATERIAL AND METHODS: A prospective study was conducted, and sixty consecutive patients proposed to shoulder arthroscopic surgery were selected. Before surgery, a radiographic evaluation was performed with a supine and a Fisk radiograph. Most supine radiographs (>75%) were non-interpretable and were excluded from the study. As some Fisk radiographs (26.7%) were also non-interpretable, that left 44 interpretable radiographs in the study. These were measured for medial opening angle, total opening angle, width and depth of the bicipital groove. The radiographic measurements and the presence of LHBT pathology, as assessed at arthroscopy, were correlated. RESULTS: Radiographic evaluation of the bicipital groove showed a mean medial opening angle of 53±15o (23 - 90), a mean total opening angle of 80±26o (30 - 135), a mean width of 10.3±2.5mm (6 - 19) and a mean depth of 4.1±1.5mm (1 - 8). Men had higher medial opening angle (60 vs 50o, p=0.044) and wider grooves (11.9 vs 9.7mm, p=0.019). Twenty-five patients (56.8%) were found to have an abnormal LHBT. No correlation was found between the radiographic measurements and LHBT pathology. Only age was correlated with a LHBT lesion (61.8 vs 46.3 years, p <0.001). CONCLUSIONS: Our results show that there is no correlation between radiographic morphologic evaluation of the bicipital groove and LHBT pathology.

Oxígeno hiperbárico para la cistitis inducida por radioterapia: un seguimiento a largo plazo / Hyperbaric oxygen for radiation-induced cystitis: A long-term follow-up

INTRODUCCIÓN Y OBJETIVOS: Alrededor del 12% de los pacientes tratados con radioterapia pélvica desarrollan complicaciones en la vejiga. La terapia de oxígeno hiperbárico (TOHB) es una opción para el manejo de la cistitis hemorrágica inducida por radioterapia (CHIR). El objetivo de este estudio fue evaluar la eficacia de la TOHB para tratar la cistitis por radioterapia e identificar factores predictivos para un resultado exitoso. MATERIAL Y MÉTODOS: Revisamos retrospectivamente a 105 pacientes diagnosticados de CHIR que recibieron un tratamiento de TOHB entre 2007 y 2016 en nuestro centro. Los pacientes recibieron oxígeno al 100% en una cámara hiperbárica multiplaza a 2,4 ATA durante 80 min. Todos los pacientes cumplimentaron un cuestionario en el que se documentaba la gravedad de los síntomas previos a la TOHB y tras el período de seguimiento. RESULTADOS: Después de una media de 40 sesiones de TOHB, hubo una tasa de éxito del 92,4% en el control de la hematuria. Durante el período de seguimiento (mediana de 63 meses), el 24,7% de los pacientes presentaron recurrencia de la hematuria. La puntuación media de las variables evaluadas en el cuestionario -disuria, frecuencia urinaria y hematuria- fue significativamente menor después del período de seguimiento (p <0,05). Nuestros datos muestran que cuanto antes se administre la TOHB después del primer episodio de hematuria, se logran mejores tasas de respuesta y se registran menores recurrencias en relación con la hematuria (p <0,05). No se observaron complicaciones graves. CONCLUSIONES: Nuestros resultados apoyan la seguridad y los beneficios a largo plazo de la TOHB para la CHIR y otros síntomas molestos de la vejiga, lo que supondría una mejora en la calidad de vida de nuestros pacientes

INTRODUCTION AND OBJECTIVES: Bladder complications may be seen in up to 12% of patients treated with pelvic irradiation. Hyperbaric oxygen therapy (HBOT) is an option for the management of radiation-induced hemorrhagic cystitis (RIHC). The aim of this study was to evaluate the efficacy of HBOT in radiation cystitis and to identify the predictive factors for a successful outcome. MATERIAL AND METHODS: We retrospectively reviewed 105 patients diagnosed with RIHC which were treated with HBOT between 2007 and 2016 in our institution. Patients received 100% oxygen in a multiplace hyperbaric chamber at 2.4atm for 80minutes. All patients fulfilled a questionnaire documenting symptom severity pre-HBOT and at the end of the follow-up period. RESULTS: After a median of 40 HBOT sessions, there was success rate of 92,4% in the control of hematuria. During our follow-up period (median of 63 months) 24,7% patients presented with recurrence of hematuria. The mean score of the questionnaire-assessed variables: dysuria, urinary frequency and hematuria, was significantly lower after the follow-up period (P<.05). Our data shows that the sooner HBOT is delivered after the first episode of hematuria, better response rates are achieved and lower recurrences concerning hematuria were registered (P<.05). No serious complications were observed. CONCLUSIONS: Our results support the safety and long-term benefits of HBOT on RIHC and other distressful bladder symptoms, which represents an expected improvement of quality of life in our patients
