Applying enhanced recovery principles to emergency laparotomy in penetrating abdominal trauma: a case-matched study.

PURPOSE: The implementation of enhanced recovery after surgery programs (ERPs) has significantly improved outcomes within various surgical specialties. However, the suitability of ERPs in trauma surgery remains unclear. This study aimed to (1) design and implement an ERP for trauma laparotomy patients; (2) assess its safety, feasibility, and efficacy; and (3) compare the outcomes of the proposed ERP with conventional practices. METHODS: This case-matched study prospectively enrolled hemodynamically stable patients undergoing emergency laparotomy after penetrating trauma. Patients receiving the proposed ERP were compared to historical controls who had received conventional treatment from two to eight years prior to protocol implementation. Cases were matched for age, sex, injury mechanism, extra-abdominal injuries, and trauma scores. Assessment of intervention effects were modelled using regression analysis for outcome measures, including length of hospital stay (LOS), postoperative complications, and functional recovery parameters. RESULTS: Thirty-six consecutive patients were enrolled in the proposed ERP and matched to their 36 historical counterparts, totaling 72 participants. A statistically significant decrease in LOS, representing a 39% improvement in average LOS was observed. There was no difference in the incidence of postoperative complications. Opioid consumption was considerably lower in the ERP group (p < 0.010). Time to resumption of oral liquid and solid intake, as well as to the removal of nasogastric tubes, urinary catheters, and abdominal drains was significantly earlier among ERP patients (p < 0.001). CONCLUSION: The implementation of a standardized ERP for the perioperative care of penetrating abdominal trauma patients yielded a significant reduction in LOS without increasing postoperative complications. These findings demonstrate that ERPs principles can be safely applied to selected trauma patients.

Niobic acid as a support for microheterogeneous nanocatalysis of sodium borohydride hydrolysis under mild conditions.

This study explores the stabilization by niobic acid, of Pt, Ni, Pd, and Au nanoparticles (NPs) for the efficient microheterogeneous catalysis of NaBH4 hydrolysis for hydrogen production. Niobic acid is the most widely studied Nb2O5 polymorph, and it is employed here for the first time for this key reaction relevant to green energy. Structural insights from XRD, Raman, and FTIR spectroscopies, combined with hydrogen production data, reveal the role of niobic acid's Brønsted acidity in its catalytic activity. The supported NPs showed significantly higher efficiency than the non-supported counterparts regarding turnover frequency, average hydrogen production rate, and cost. Among the tested NPs, PtNPs and NiNPs demonstrate the most favorable results. The data imply mechanism changes during the reaction, and the kinetic isotope assay indicates a primary isotope effect. Reusability assays demonstrate consistent yields over five cycles for PtNPs, although catalytic efficiency decreases, likely due to the formation of reaction byproducts.

Development and mechanical-functional validation of 3D-printed laparoscopic forceps.

INTRODUCTION: 3-dimensional printing has enabled the development of unique and affordable additive manufacturing, including the prototyping and production of surgical forceps. Objective: demonstrate the development, 3D printing and mechanical-functional validation of a laparoscopic grasping forceps. METHODS: the clamp was designed using a computer program and printed in 3 dimensions with polylactic acid (PLA) filament and added 5 screws for better leverage. Size and weight measurements were carried out, as well as mechanicalfunctional grip and rotation tests in the laboratory with a validated simulator. RESULTS: Called "Easylap", the clamp weighed 48 grams, measured 43cm and was printed in 8 pieces, taking an average of 12 hours to produce. It allowed the simulation of the functional characteristics of laparoscopic pressure forceps, in addition to the rotation and rack locking mechanism. However, its strength is reduced due to the material used. CONCLUSION: It is possible to develop plastic laparoscopic grasping forceps through 3-dimensional printing.

Special Considerations for Brazilian Transgender Patients in the United States: A Commentary.

Despite facing many social and structural challenges inside and outside of health systems, transgender and gender diverse (TGD) Brazilian immigrants in the U.S. are understudied, and their barriers to care are largely unnamed. In this commentary, we build on existing literature and our experiences at a safety-net community health system that sees a high volume of Brazilian patients to discuss challenges facing TGD Brazilian immigrant populations. We highlight that while Brazilian TGD populations face discrimination in Brazil, major challenges persist upon immigrating to the U.S., and include: difficulty updating identity documents and changing immigration status, barriers seeking general and specialized health care (including finding bilingual and bicultural providers), challenges navigating complex health and insurance systems, and a lack of community supports. We end by recommending more coordinated efforts between health care and community organizations to help ensure the health and wellness of TGD Brazilian immigrants in the United States.

Evaluation of long-term immune response in cattle to botulism using a recombinant E. coli bacterin formulated with Montanide™ ISA 50 and aluminum hydroxide adjuvants.

Botulism is a severe disease caused by potent botulinum neurotoxins (BoNTs) produced by Clostridium botulinum. This disease is associated with high-lethality outbreaks in cattle, which have been linked to the ingestion of preformed BoNT serotypes C and D, emphasizing the need for effective vaccines. The potency of current commercial toxoids (formaldehyde-inactivated BoNTs) is assured through tests in guinea pigs according to government regulatory guidelines, but their short-term immunity raises concerns. Recombinant vaccines containing the receptor-binding domain have demonstrated potential for eliciting robust protective immunity. Previous studies have demonstrated the safety and effectiveness of recombinant E. coli bacterin, eliciting high titers of neutralizing antibodies against C. botulinum and C. perfringens in target animal species. In this study, neutralizing antibody titers in cattle and the long-term immune response against BoNT/C and D were used to assess the efficacy of the oil-based adjuvant compared with that of the aluminum hydroxide adjuvant in cattle. The vaccine formulation containing Montanide™ ISA 50 yielded significantly higher titers of neutralizing antibody against BoNT/C and D (8.64 IU/mL and 9.6 IU/mL, respectively) and induced an immune response that lasted longer than the response induced by aluminum, extending between 30 and 60 days. This approach represents a straightforward, cost-effective strategy for recombinant E. coli bacterin, enhancing both the magnitude and duration of the immune response to botulism.

Social and individual vulnerability factors associated with syphilis among populations living on islands in the Brazilian Amazon.

BACKGROUND: The repercussions of the syphilis epidemic differ according to populations. Identifying and acknowledging the differences and specificities of populations is fundamental in the design and implementation of policies aimed at assisting the groups most vulnerable to syphilis. OBJECTIVE: To estimate the prevalence of antibodies against Treponema pallidum and associated vulnerability factors among riverside populations of a capital city in the Brazilian Amazon. METHODS: Cross-sectional study was conducted among residents of the periurban islands in Belém, northern Brazil, from August 2020 to January 2021. The inclusion criterion was being a resident of the riverside communities of the Combú Environmental Protection Area, aged 18 years or over. The participants responded to questionnaire and were tested for syphilis using rapid test. Data were analyzed using multiple logistic regression by Minitab version 20® software. RESULTS: Overall, a total of 325 riverine were included. Age varied from 18 to 91 years (average 40 years). Prevalence of markers for syphilis was 5.9% (95% CI: 3.3%-8.4%). The multiple regression showed that as age increases, the chances of having syphilis also increase (p = 0.001; aOR: 1.04) and riverside dwellers with more than one sexual partner in the last 6 months had more than four chances of having syphilis compared to people who had only one sexual partner (p = 0.007; aOR: 4.20). CONCLUSION: Syphilis circulates among traditional populations in the Amazon and is associated with factors of social and individual vulnerability.

Development of a low-cost simulator for training in hemorrhoidal ligation

Introduction: Rubber band ligation is a minimally invasive outpatient hemorrhoid treatment with low cost, low complication rates, and rapid realization. It is performed with the aid of an anoscope and uses a rubber ring that surrounds the hemorrhoidal nipple, causing compression of the vascular structures of the tissue, leading to necrosis and remission of the hemorrhoid. No device for training this essential procedure for treating this pathology has been identified in the literature. Therefore, we aim to develop a low-cost simulator for training hemorrhoidal rubber ligation. Methods: The model was constructed using PVC pipe wrapped in neoprene fabric. Hemorrhoidal nipples and the pectineal line were also simulated using fabric and sewing threads. The procedure is performed with conventional anoscope and ligature forceps. Conclusion: The device in question is a low-cost simulation model designed to train the skills required to perform a rubber band ligation and review the basic anatomy of the anal canal during anoscopy. Given these qualities, the model can be used for academic training due to its low cost and simplicity of application. (AU)

Leprosy and tuberculosis control scenario of the national program for the improvement of access and quality of primary care in Brazil.

BACKGROUND: In Brazil, despite advances in public health policies aimed at eliminating and controlling infectious and parasitic diseases, the incidence of neglected diseases is still high. The epidemiological scenario in Brazil of diseases such as tuberculosis and leprosy evidences a public policy agenda that has not been resolute in terms of control, nor in terms of elimination. OBJECTIVE: To analyze the actions of diagnosis and treatment of leprosy and tuberculosis in the context of primary health care. METHODS: In this ecological study, data from the third cycle of the Program for the Improvement of Access and Quality of Primary Care were extracted from electronic address of the Primary Health Care Secretariat of Brazil in the area of Actions, Programs and Strategies. A total of 37,350 primary health care teams were that answered the questionnaire were eligible, with variables extracted from leprosy and tuberculosis control actions. The municipalities were grouped according to the characteristic of the Brazilian municipality. The partition chi-square and the Residuals Test were used to assess whether there was a difference in the proportion of tuberculosis and leprosy actions between types of municipalities. Statistics were carried out using Minitab 20 and Bioestat 5.3. RESULTS: Regarding the leprosy treatment location, there is a higher proportion of people referred to be treated at the reference in adjacent rural (p = 0.0097) and urban (p < 0.0001) municipalities; monitoring of people with leprosy referred to the service network (p. = 0.0057) in remote rural areas. Lower proportion of teams requesting bacilloscopy in remote rural areas (p = 0.0019). Rural areas have a higher proportion of teams that diagnose new cases (p = 0.0004). Regarding the actions of diagnosis and treatment of tuberculosis. There is a higher proportion of teams that carry out consultations at the unit itself in rural areas when compared to adjacent intermediaries (p = 0.0099) and urban (p < 0.0001); who requested sputum smear microscopy in adjacent intermediaries (p = 0.0021); X-ray in adjacent intermediaries (p < 0.0001) and urban (p < 0.0001); collection of the first sputum sample in urban (p < 0.0001) and adjacent rural areas (p < 0.0001); directly observed treatment (p < 0.0001) in adjacent rural municipalities. CONCLUSION: There are inequalities in the diagnosis and treatment of leprosy and tuberculosis among the types of municipalities.

Trauma surgery workforce in the state of Rio Grande do Sul, Brazil.

OBJECTIVE: to describe the current scope of certified trauma surgeons trained in the state of Rio Grande do Sul, including demographic data, geographic distribution, remuneration, and perspectives related to this specialty. METHOD: cross-sectional survey based on information collected through an electronic questionnaire sent to potential participants. RESULTS: the response rate was 64% (n=75). There was a predominance of males (72%) with a mean age of 43 years. Most surgeons graduated from the Hospital de Pronto Socorro de Porto Alegre, and work in referral centers for trauma surgery in the capital and metropolitan region. More than 60% did not have any other training in a surgical subspecialty, though only a third stated that trauma surgery is their main source of income. CONCLUSION: trauma centers are poorly distributed and most surgeons work in referral hospitals in the metropolitan region of Porto Alegre. Due to the lack of recognition, limited financial income and shift work patterns, the career in trauma surgery care is unattractive, with only one third of surgeons performing most of their activities in this specialty.

Burnout Syndrome in Selectable Athletes for the Brazilian Handball Team-Children Category.

To investigate the presence of burnout syndrome in child athlete tryouts for the Brazilian Handball Team, before and after the National Development and Technical Improvement Camp is of great interest. A correlational study, with longitudinal design of the before-and-after type, carried out with 64 male athletes in the children's category, immersed in the National Camp for Development and Improvement of Handball Technique, in the municipality of São Bernardo do Campo, São Paulo, Brazil, in December 2018. To evaluate burnout syndrome, we used the Athlete Burnout Questionnaire (ABQ). There was a statistically significant increase of the mean scores for burnout and dimensions (Physical and Emotional Exhaustion = 1.5 to 1.6; p-value < 0.001; Reduced Sense of Accomplishment = 2.7 to 2.9; p-value < 0.001; Sports Devaluation = 1.4 to 1.6; p-value < 0.001; and General Burnout = 1.9 to 2.0; p-value < 0.001). The athletes selected for the national team had lower mean scores for general burnout and dimensions (Physical and Emotional Exhaustion = 1.5; Reduced Sense of Accomplishment = 2.7; Sports Devaluation = 1.5; General Burnout = 1.9). The National Camp for Development and Technical Improvement can have a negative impact on the mental health of athletes. This event is important to select the competitors with greater ability to face the pressure and adversities present in the sport environment.

Abstract This article aimed to analyze the types of work bond of nurses from Primary Health Care in Brazil. This was a cross-sectional study of a quantitative and descriptive approach. Secondary microdata related to the breakdown of the external evaluation research of the Access Improvement Program and the Quality of Basic Care were used. As for the type of bond, except for the Northern Region (33.70%), all other regions presented as the main respondent for statutory public servants: South (66.20%), Central-West (56.50%), Northeast (40.33%), Southeast (36.69%). Nurses with temporary contracts for public administration and temporary service contracts had important participation in the Northeast (29.51% and 19.33%) and Central-West (16.03% and 17.86%). Contract and employee through Consolidation of Labor Laws had more expression in the Southeast (23.54% and 8.27%) and in the South (5.93% and 19.31%). In the Southeast, the participation of workers employed by social health organizations was expressive. The growing presence of precarious labor links was noted, to the detriment of stable bonds. The new forms of flexible organization of work relationships bring significant impact to the work process, overload nurses in inadequate working conditions, and compromise the quality of care, reducing the resolubility of Primary Care.

Seroprevalence of Chlamydia trachomatis and Associated Factors among Vulnerable Riverine in the Brazilian Amazon.

Due to social and individual conditions and access to health services, Amazonian riverside populations are highly vulnerable to sexually transmitted infections, including Chlamydia trachomatis. The aim is to estimate the seroprevalence of Chlamydia trachomatis and analyze the associated factors among riverside dwellers in a capital city in the Brazilian Amazon. A cross-sectional study was carried out with residents of the Combu Island, Belém. The study sample was calculated using the population survey technique in the EPI INFO. Only people aged 18 and over were included. ELISA serology was performed to detect antibodies against Chlamydia trachomatis. For data collection, a form containing vulnerability factor questions was applied. Binary regression analysis was performed using the Minitab 20 program. The study sample consisted of 325 participants. The prevalence of IgG/IgM antibodies against Chlamydia trachomatis was 22.2% and 5.5%, respectively. In the multiple regression, only participants with a broken condom were more likely to have antibodies against the bacteria (OR: 1.90; 95% CI: 1.01; 3.37; p = 0.046). Seroprevalence was associated with condom breakage. This factor demonstrates that despite having an attitude towards condom use, probably, they may have inadequate knowledge about the correct practice of introduction.

Predictive factors of mortality in damage control surgery for abdominal trauma.

INTRODUCTION: damage control surgery (DCS) is well recognized as a surgical strategy for patients sustaining severe abdominal trauma. Literature suggests the indications, operative times, therapeutic procedures, laboratory parameters and intraoperative findings have a direct bearing on the outcomes. OBJECTIVE: to analyze the clinical profile of patients undergoing DCS and determine predictors of morbidity and mortality. METHODS: a retrospective cohort study was conducted on all patients undergoing DCS following abdominal trauma from November 2015 and December 2021. Data on subjects' demographics, baseline presentation, mechanism of injury, associated injuries, injury severity scores, laboratory parameters, operative details, postoperative complications, length of stay and mortality were assessed. A binary logistic regression analysis was performed to determine potential risk factors for mortality. RESULTS: During the study period, 696 patients underwent trauma laparotomy. Of these, 8.9% (n=62) were DCS, with more than 80% due to penetrating mechanisms. Overall mortality was 59.6%. In the logistic regression stratified by survival, several variables were significantly associated with mortality, including hypotension, and altered mental status at admission, intraoperative cardiorespiratory arrest, need for resuscitative thoracotomy, metabolic acidosis, hyperlactatemia, coagulopathy, fibrinolysis, and severity of the trauma injury scores. CONCLUSION: DCS may be appropriate in critically injured patients; however, it remains associated with significant morbidity and high mortality, even at specialized trauma care centers. From pre and postoperative clinical and laboratory parameters, it was possible to predict the risk of death in the studied sample.
