RESUMO

Objectives. The prevalence of patients with prior stroke is increasing globally. Accordingly, there is a need for up-to-date evidence of patient-related prognostic factors for stroke recurrence, post stroke myocardial infarction (MI) and death based on long-term follow-up of stroke survivors. For this purpose, the RIALTO study was established in 2004. Design. A prospective cohort study in which patients diagnosed with ischemic stroke (IS) or transient ischemic attack (TIA) in three Copenhagen hospitals were included. Data were collected from medical records and by structured interview. Data on first stroke recurrence, first MI and all-cause death were extracted from the Danish National Patient Registry and the Danish Civil Registration System. Results. We included 1215 patients discharged after IS or TIA who were followed up by register data from April 2004 to end of 2018 giving a median follow-up of 3.5-6.9 years depending on the outcome. At the end of follow-up 406 (33%) patients had been admitted with a recurrent stroke, 100 (8%) had a MI and 822 (68%) had died. Long-term prognostic predictors included body mass index, diabetes, antihypertensive and lipid lowering treatment, smoking, a sedentary lifestyle as well as poor self-rated health and psychosocial problems. Conclusions. Long-term risk of recurrent stroke and MI remain high in patients discharged with IS or TIA despite substantial improvements in tertiary preventive care in recent decades. Continued attention to the patient risk profile among patients surviving the early phase of stroke, including comorbidities, lifestyle, and psychosocial challenges, is warranted.

RESUMO

OBJECTIVES: Electrocardiogram (ECG) and measurement of plasma brain natriuretic peptides (BNP) are established markers of right ventricular dysfunction (RVD) in the setting of acute pulmonary embolism (PE) but their value at long-term follow-up is largely unknown. The purpose of this prospective study was to determine the prevalence of ECG abnormalities, describe levels of N-terminal proBNP (NT-proBNP), and establish their association with dyspnea at long-term follow-up after PE. DESIGN: All Swedish patients diagnosed with acute PE in 2005 (n = 5793) were identified through the Swedish National Patient Registry. Surviving patients in 2007 (n = 3510) were invited to participate. Of these, 2105 subjects responded to a questionnaire about dyspnea and comorbidities. Subjects with dyspnea or risk factors for development of chronic thromboembolic pulmonary hypertension were included in the study in a secondary step, which involved collection of blood samples and ECG registration. RESULTS: Altogether 49.3% had a completely normal ECG. The remaining participants had a variety of abnormalities, 7.2% had atrial fibrillation/flutter (AF). ECG with any sign of RVD was found in 7.2% of subjects. Right bundle branch block was the most common RVD sign with a prevalence of 6.4%. An abnormal ECG was associated with dyspnea. AF was associated with dyspnea, whereas ECG signs of RVD were not. 61.2% of subjects had NT-proBNP levels above clinical cut-off (>125 ng/L). The degree of dyspnea did not associate independently with NT-proBNP levels. CONCLUSIONS: We conclude that the value of ECG and NT-proBNP in long term follow-up after PE lies mostly in differential diagnostics.

RESUMO

Background: Exacerbations of chronic obstructive pulmonary disease (COPD) were reported less frequently during the COVID-19 pandemic. We report real-world data on COPD exacerbation rates before and during this pandemic. Methods: Exacerbation patterns were analysed using electronic medical records or claims data of patients with COPD before (2017-2019) and during the COVID-19 pandemic (2020 through early 2022) in France, Germany, Italy, the United Kingdom and the United States. Data from each country were analysed separately. The proportions of patients with COPD receiving maintenance treatment were also estimated. Results: The proportion of patients with exacerbations fell 45-78% across five countries in 2020 versus 2019. Exacerbation rates in most countries were reduced by >50% in 2020 compared with 2019. The proportions of patients with an exacerbation increased in most countries in 2021. Across each country, seasonal exacerbation increases seen during autumn and winter in pre-pandemic years were absent during the first year of the pandemic. The percentage of patients filling COPD prescriptions across each country increased by 4.53-22.13% in 2019 to 9.94-34.17% in 2021. Conclusion: Early, steep declines in exacerbation rates occurred in 2020 versus 2019 across all five countries and were accompanied by a loss of the seasonal pattern of exacerbation.

RESUMO

Purpose: Chronic obstructive pulmonary disease (COPD) and metabolic syndrome (MetS) are among the most prevalent conditions that might predispose individuals to life-threatening events. We aimed to examine their associations with cardiovascular (CV) events and mortality using a large-scale population dataset from the National Health Information Database in Korea. Patients and Methods: This population-based cohort study enrolled adults aged ≥40 years who had undergone more than two health examinations between 2009 and 2011. They were divided into four groups based on the presence of COPD and MetS. Analysis of the outcomes and CV events or deaths was performed from 2014 to 2019. We compared CV event incidence and mortality rates using a multivariate Cox proportional hazards model and Kaplan-Meier curves. Results: Totally, 5,101,810 individuals were included, among whom 3,738,458 (73.3%) had neither COPD nor MetS, 1,193,014 (23.4%) had only MetS, 125,976 (2.5%) had only COPD, and 44,362 (0.9%) had both. The risk of CV events was significantly higher in individuals with both COPD and MetS than in those with either COPD or MetS alone (HRs: 2.4 vs 1.6 and 1.8, respectively; all P <0.001). Similarly, among those with both COPD and MetS, all-cause and CV mortality risks were also elevated (HRs, 2.9 and 3.0, respectively) compared to the risks in those with either COPD (HRs, 2.6 and 2.1, respectively) or MetS (HRs, 1.7 and 2.1, respectively; all P <0.001). Conclusion: The comorbidity of MetS in patients with COPD increases the incidence of CV events and all-cause and cardiovascular mortality rates.

RESUMO

Purpose: Vitamin D deficiency (VDD, 25-hydroxyvitamin D < 20 ng/mL) has been reported associated with exacerbation of chronic obstructive pulmonary disease (COPD) but sometimes controversial. Research on severe vitamin D deficiency (SVDD, 25-hydroxyvitamin D < 10 ng/mL) in exacerbation of COPD is limited. Patients and Methods: We performed a retrospective observational study in 134 hospitalized exacerbated COPD patients. 25-hydroxyvitamin D was modeled as a continuous or dichotomized (cutoff value: 10 or 20 ng/mL) variable to evaluate the association of SVDD with hospitalization in the previous year. Receiver operator characteristic (ROC) analysis was performed to find the optimal cut-off value of 25-hydroxyvitamin D. Results: In total 23% of the patients had SVDD. SVDD was more prevalent in women, and SVDD group tended to have lower blood eosinophils counts. 25-hydroxyvitamin D level was significantly lower in patients who were hospitalized in the previous year (13.6 vs 16.7 ng/mL, P = 0.044), and the prevalence of SVDD was higher (38.0% vs 14.3%, P = 0.002). SVDD was independently associated with hospitalization in the previous year [odds ratio (OR) 4.34, 95% CI 1.61-11.72, P = 0.004] in hospitalized exacerbated COPD patients, whereas continuous 25-hydroxyvitamin D and VDD were not (P = 0.1, P = 0.9, separately). The ROC curve yielded an area under the curve of 0.60 (95% CI 0.50-0.71) with an optimal 25-hydroxyvitamin D cutoff of 10.4 ng/mL. Conclusion: SVDD probably showed a more stable association with hospitalization in the previous year in hospitalized exacerbated COPD patients. Reasons for lower eosinophil counts in SVDD group needed further exploration.

RESUMO

Objective: Given the established impact of exercise in reducing arterial stiffness and the potential for intermittent hypoxia to induce its elevation, this study aims to understand how oxygen desaturation during exercise affects arterial stiffness in individuals with COPD. Methods: We enrolled patients with stable COPD from China-Japan Friendship Hospital from November 2022 to June 2023. The 6-minute walk test (6-MWT) was performed with continuous blood oxygen saturation (SpO2) monitoring in these patients. The patients were classified into three groups: non-exercise induced desaturation (EID), mild-EID and severe-EID, according to the changes in SpO2 during the 6-MWT. The Cardio-Ankle Vascular Index (CAVI) and the change in CAVI (ΔCAVI, calculated as CAVI before 6MWT minus CAVI after the 6MWT) were measured before and immediately after the 6MWT to assess the acute effects of exercise on arterial stiffness. GOLD Stage, pulmonary function, and other functional outcomes were also measured in this study. Results: A total of 37 patients with stable COPD underwent evaluation for changes in CAVI (ΔCAVI) before and after the 6-MWT. Stratification based on revealed three subgroups: non-EID (n=12), mild-EID (n=15), and severe-EID (n=10). The ΔCAVI values was -0.53 (-0.95 to -0.31) in non-EID group, -0.20 (-1.45 to 0.50) in mild-EID group, 0.6 (0.08 to 0.73) in severe-EID group. Parametric tests indicated significant differences in ΔCAVI among EID groups (p = 0.005). Pairwise comparisons demonstrated significant distinctions between mild-EID and severe-EID groups, as well as between non-EID and severe-EID groups (p = 0.048 and p = 0.003, respectively). Multivariable analysis, adjusting for age, sex, GOLD stage, diffusion capacity, and blood pressure, identified severe-EID as an independent factor associated with ΔCAVI (B = 1.118, p = 0.038). Conclusion: Patients with COPD and severe-EID may experience worsening arterial stiffness even during short periods of exercise.

RESUMO

The Food and Drug Administration's (FDA's) breakthrough therapy designation (BTD) program was created to increase patient access to safe and effective therapies by supporting the efficient clinical development of qualifying, clinically meaningful therapies. Using a new data set of key development milestones for drugs approved between 2006 and 2020, including both BTD drugs and a set of comparator drugs identified by FDA experts, we estimated the BTD program's impact on time spent in late-stage clinical development, measured as the elapsed time between a drug's end-of-Phase-II meeting with regulators and its approval for marketing. Our analysis suggests that the BTD program lowers late-stage clinical development time by 30 percent. Our findings provide insight into future regulatory and innovation policies aimed at driving efficiency in medical product development to ensure timely patient access to the most clinically meaningful therapies.

RESUMO

INTRODUCTION: The quality and promptness of prehospital care for major trauma patients are vital in order to lower their high mortality rate. However, the effectiveness of this response in Portugal is unknown. The objective of this study was to analyze response times and interventions for major trauma patients in the central region of Portugal. METHODS: This was a retrospective, descriptive study, using the 2022 clinical records of the National Institute of Medical Emergency's differentiated resources. Cases of death prior to arrival at the hospital and other non-transport situations were excluded. Five-time intervals were determined, among which are the response time (T1, between activation and arrival at the scene), on-scene time (T2), and transportation time (T5; between the decision to transport and arrival at the emergency service). For each ambulance type, averages and dispersion times were calculated, as well as the proportion of cases in which the nationally and internationally recommended times were met. The frequency of recording six key interventions was also assessed. RESULTS: Of the 3366 records, 602 were eliminated (384 due to death), resulting in 2764 cases: nurse-technician ambulance (SIV) = 36.0%, physician- nurse ambulance (VMER) = 62.2% and physician-nurse helicopter = 1.8%. In a very large number of records, it was not possible to determine prehospital care times: for example, transport time (T5) could be determined in only 29%, 13% and 8% of cases, respectively for SIV, VMER and helicopter. The recommended time for stabilization (T2 ≤ 20 min) was met in 19.8% (SIV), 36.5% (VMER) and 18.2% (helicopter). Time to hospital (T5 ≤ 45 min) was achieved in 80.0% (SIV), 93.1% (VMER) and 75.0% (helicopter) of the records. The administration of analgesia (42% in SIV) and measures to prevent hypothermia (23.5% in SIV) were the most recorded interventions. CONCLUSION: There was substantial missing data on statuses and a lack of information in the records, especially in the VMER and helicopter. According to the records, the time taken to stabilize the victim on-scene often exceeded the recommendations, while the time taken to transport them to the hospital tended to be within the recommendations.


Introdução: A qualidade e rapidez do socorro pré-hospitalar à pessoa vítima de trauma major é vital para diminuir a sua elevada mortalidade. Contudo, desconhece-se a efetividade desta resposta em Portugal. O objetivo deste estudo foi analisar os tempos de resposta e as intervenções realizadas às vítimas de trauma major na região centro de Portugal. Métodos: Estudo retrospetivo, descritivo, utilizando os registos clínicos de 2022 dos meios diferenciados do Instituto Nacional de Emergência Médica. Casos de óbito pré-chegada ao hospital e outras situações de não transporte foram excluídos. Determinaram-se cinco tempos, entre os quais o tempo de resposta (T1, decorrente entre acionamento e chegada ao local), o tempo no local (T2) e o tempo de transporte (T5, intervalo entre a decisão de transporte e a chegada ao serviço de urgência). Foram calculadas médias e medidas de dispersão para cada meio, bem como a proporção de casos em que foram cumpridos os tempos recomendados nacional e internacionalmente. Avaliou-se também a frequência de registo de seis intervenções chave. Resultados: Dos 3366 registos, eliminaram-se 602 (384 por óbito), resultando em 2764 casos [suporte imediato de vida (SIV) = 36,0%, viaturas médicas de emergência e reanimação (VMER) = 62,2%, helicóptero de emergência médica (HEM) = 1,8%]. Num elevado número de registos não foi possível determinar tempos de socorro: por exemplo, o tempo de transporte (T5) foi determinável em apenas 29%, 13%, e 8% dos casos, respetivamente para SIV, VMER e HEM. O tempo recomendado para a estabilização (T2 ≤ 20 min), foi cumprido em 19,8% (SIV), 36,5% (VMER), e 18,2% (HEM) dos regis- tos. Já o tempo de transporte (T5 ≤ 45 min) foi cumprido em 80,0% (SIV), 93,1% (VMER) e 75,0% (HEM) dos registos (avaliáveis). A administração de analgesia (42% na SIV) e as medidas de prevenção de hipotermia (23,5% na SIV) foram as intervenções mais registadas. Conclusão: Observaram-se muitos status omissos e falta de informação nos registos, sobretudo na VMER e HEM. De acordo com os registos, o tempo no local superou frequentemente as recomendações, enquanto o tempo de transporte tende a estar dentro das normas.

RESUMO

INTRODUCTION: Minimally invasive surgery has been increasingly accepted and used in colorectal surgery. Several studies report that robotic surgery may provide advantages over 'conventional' laparoscopy, namely in rectal surgery. This paper provides an account of the first three years of experience with robotic surgery in the Unidade de Patologia Colorretal of the Unidade Local de Saúde S. José. METHODS: Variables were defined to develop a prospective database containing the data of consecutive patients operated by three internationally certified colorectal surgeons using the Da Vinci Xi® system between November 2019 and October 2022. The database was converted into an anonymized version that was used for this study. The analysis was performed on the data of all the patients operated during this period. RESULTS: Eighty patients were included, 47 male, median age 70 years, and median BMI 26 kg/m2 . ASA score was II in 53.7% and III in 41.3% of pa- tients. Of the total, 97.6% had malignant or potentially malignant disease. Operative procedures consisted of 34 colectomies proximal to the splenic flexure, 20 distal colectomies and 26 anterior resections. There were two synchronous resections of liver metastases. Early perioperative outcomes and histopathological results were analyzed: median operative time: 300 minutes; median estimated blood loss: 50 mL; conversion rate: 2.5%; median days until first bowel movement: three days; median length of hospital stay: six days; complication rate: 20%, of which 5% were Clavien III and 0% Clavien IV/V; anastomotic leak rate: 2.5%; 30-day readmission rate: 1.3%; median lymph nodes resected: 20; R0 resection rate: 100%; mesorectal integrity rate: 95,8% complete/near complete. CONCLUSION: Our results show that the adoption of robotic colorectal surgery in our center was safe and resulted in similar or improved short-term clinical outcomes and histopathological results when compared to those described in the literature.


Introdução: A utilização da cirurgia minimamente invasiva no tratamento da patologia colorretal é hoje cientificamente aceite e o seu uso na prática clí- nica diária tem vindo a aumentar de forma sustentada. Diversos estudos indicam que a abordagem robótica pode trazer vantagens sobre a laparoscopia 'convencional', especialmente na cirurgia do reto. Este trabalho descreve e analisa os resultados dos primeiros três anos de cirurgia robótica na Unidade de Patologia Colorretal da Unidade Local de Saúde S. José. Métodos: Foram definidas as variáveis a analisar e construída uma base de dados prospetiva com os dados referentes aos doentes operados conse- cutivamente por três cirurgiões colorretais, acreditados internacionalmente na utilização do sistema Da Vinci Xi®, entre novembro de 2019 e outubro de 2022. A base de dados foi convertida numa versão anonimizada e foi sobre essa mesma que se procedeu à análise de dados. Foram analisados os dados de todos doentes operados nesse período. Resultados: Foram incluídos 80 doentes, 47 homens, mediana de idade de 70 anos e de IMC de 26 kg/m2 . O score ASA era II em 53,7% e III em 41,3% dos doentes. Do total, 97,6% apresentavam doença maligna ou potencialmente maligna. Realizaram-se 34 colectomias proximais ao ângulo esplénico, 20 distais e 26 ressecções anteriores do reto. Houve ressecção síncrona de metástases hepáticas em dois casos. Foram analisados os resultados peri-operatórios a curto prazo e histopatológicos: duração (mediana): 300 minutos; perda hemática estimada (mediana): 50 mL; taxa de conversão: 2,5%; dias até retomar trânsito intestinal (mediana): três dias; dias de internamento (mediana): seis dias; taxa de complicações pós-operatórias: 20%, das quais 5% Clavien III e 0% Clavien IV/V; taxa de deiscência anastomótica: 2,5%; taxa de reintervenção: 2,5%; taxa de readmissão pós-alta: 1,3%; gânglios linfáticos ressecados (mediana): 20; taxa de ressecção R0: 100%; taxa de integridade mesorretal: 95,8% completo/quase completo. Conclusão: Os nossos resultados mostram que a introdução da cirurgia colorretal robótica no nosso centro foi segura e garantiu resultados clínicos a curto prazo e histopatológicos semelhantes ou favoráveis face aos descritos na literatura.

RESUMO

Objective: To determine if short-duration peripherally inserted central catheters (PICCs) cause a hypercoagulable state in healthy dogs, based on point-of-care viscoelastic coagulation monitor (VCM). Animals: Ten beagle dogs were randomly and equally allocated into control and PICC groups. Procedure: Control dogs had VCM analysis on whole blood following direct venipuncture before sedation (T0) and 2 h after sedation (T2). In the experimental group, a PICC was placed (medial saphenous or femoral vein) under sedation and removed after 4 h, with measurements before placement (T0) and 2 and 6 h after placement (T2 and T6, respectively). Parametric data were analyzed using 1-way ANOVA with Holm-Sídák test for multiple comparisons and paired or unpaired Student's t-test. Nonparametric data were analyzed using Friedman test with Dunn multiple comparison test for Wilcoxon matched-pairs signed-rank test, and Mann-Whitney U test for PICC group, control group, and to compare PICC versus control groups, respectively. Results: Clot formation time was longer at T2 versus T6 (P = 0.0342, but not clinically relevant) in the PICC group, with no significant differences between the PICC and control groups. Conclusion and clinical relevance: Short-term placement of a PICC line did not alter viscoelastic endpoints in healthy beagles.


L'utilisation de courte durée d'un cathéter central inséré par voie périphérique n'affecte pas les paramètres viscoélastiques chez les chiens sains. Objectif: Déterminer si les cathéters centraux insérés par voie périphérique (CCIP) pour une courte durée provoque un état d'hypercoagulabilité chez des chiens en bonne santé sur la base des mesures du Viscoelastic Coagulation Monitor (VCM) au point de soins. Animaux: Dix chiens sains de race beagle ont été choisis et répartis de façon égale et aléatoire dans un groupe témoin et un groupe de CCIP. Procédure: Les chiens témoins ont eu une prise de sang et analyse par VCM avant sédation (T0) et 2 heures après la sédation (T2). Dans le groupe expérimental, un CCIP a été mis en place (veines saphènes ou fémorales médiales) sous sédation et retiré après 4 heures. Les mesures viscoélastiques sur le sang frais ont été effectuées avant la pose du CCIP (T0), 2 heures après la pose (T2) et 2 heures après le retrait/6 heures après la pose du cathéter (T6). L'analyse statistique des données paramétriques a été faite par le test ANOVA à un facteur avec un test de comparaisons multiples de Holm-Sídák pour le groupe CCIP, un test t de Student apparié pour le groupe témoin, et un test t de Student non apparié pour comparer les groupes CCIP et témoin. Les données non paramétriques ont été analysées à l'aide du test de Friedman avec un test de comparaison multiple de Dunn pour le groupe CCIP, du test de rang signé de Wilcoxon pour le groupe témoin et du test de Mann-Whitney U pour comparer les groupes CCIP et témoin. Résultats: Pour le groupe CCIP, le temps de formation du caillot à T2 était plus long mais non cliniquement pertinent. comparativement à T6 (P = 0,0342) et il n'y avait aucune différence significative entre les groupes CCIP et témoin. Conclusion et pertinence clinique: La pose d'un CCIP pour une courte durée n'a pas modifié les variables viscoélastiques chez les chiens beagle en bonne santé.(Traduit par les auteurs).

RESUMO

ABSTRACT: This cross-sectional observational study examined associations among symptom burden, lifetime duration of estrogen exposure, and serum antimüllerian hormone (AMH) levels among women living with HIV (n = 98) using bivariate bias-corrected Pearson correlations and multiple correspondence analyses. The mostly Black (85.6%) sample of women, with a mean age of 50 years (SD 12.6 years), exhibited no significant reproductive history factors and symptom burden interrelationships or significant associations between lifetime duration of estrogen exposure and symptoms. Predictably, serum AMH levels were lower among older women; however, less predictable were its significant relationships with months living with HIV (r = -0.362), months on ART (r = -0.270), and CD4+ T-cell nadir (r = 0.347). Symptom-symptom relationships support a fatigue, pain, sleep, anxiety, and depression symptom cluster. The hypotheses were not supported by cross-sectional observation. Further studies should explore variation in relationships between HIV, estrogen exposure, ovarian reserve, and AMH levels over time.

RESUMO

Determining short-lived intermediate structures in chemical reactions is challenging. Although ultrafast spectroscopic methods can detect the formation of transient intermediates, real-space structures cannot be determined directly from such studies. Time-resolved serial femtosecond crystallography (TR-SFX) has recently proven to be a powerful method for capturing molecular changes in proteins on femtosecond timescales. However, the methodology has been mostly applied to natural proteins/enzymes and limited to reactions promoted by synthetic molecules due to structure determination challenges. This work demonstrates the applicability of TR-SFX for investigations of chemical reaction mechanisms of synthetic metal complexes. We fix a light-induced CO-releasing Mn(CO)3 reaction center in porous hen egg white lysozyme (HEWL) microcrystals. By controlling light exposure and time, we capture the real-time formation of Mn-carbonyl intermediates during the CO release reaction. The asymmetric protein environment is found to influence the order of CO release. The experimentally-observed reaction path agrees with quantum mechanical calculations. Therefore, our demonstration offers a new approach to visualize atomic-level reactions of small molecules using TR-SFX with real-space structure determination. This advance holds the potential to facilitate design of artificial metalloenzymes with precise mechanisms, empowering design, control and development of innovative reactions.

RESUMO

Objective: To compare cervical ripening time with the use of vaginal Misoprostol plus Hyoscine-N-Butylbromide, with vaginal Misoprostol alone. Design: A double-blind randomized controlled trial with Pan-African Clinical Trials Registry (PACTR) approval number PACTR202112821475292. Setting: Federal Medical Centre, Asaba, Nigeria. Participants: A total of 126 eligible antenatal patients for cervical ripening were enrolled. Interventions: Participants in Group A had 25µg of vaginal misoprostol with 1ml of intramuscular placebo, and those in Group B had 25µg of vaginal misoprostol with 20mg of Intramuscular Hyoscine (1 ml). Oxytocin infusion was used when indicated, and the labour was supervised as per departmental protocol. Main outcome measure: Cervical ripening time. Results: The mean cervical ripening time was statistically significantly shorter in the hyoscine group (8.48±4.36 hours) than in the placebo group (11.40±7.33 hours); p-value 0.02, 95% CI 0.80-5.05. There was no statistically significant difference in the mean induction-delivery interval in Group A (7.38±5.28 hours) compared to Group B (7.75±5.04 hours), with a value of 0.54. The mode of delivery was comparable. However, women in Group B (53, 84.1%) achieved more vaginal deliveries than women in Group A (50, 79.4%); p-value 0.49. Thirteen women in Group A (20.6%) had a caesarean section, while ten women (15.9%) in Group B had a caesarean section (p-value 0.49, RR 0.94, CI 0.80-1.11). Adverse maternal and neonatal outcomes were not statistically significant between the two groups. Conclusion: Intramuscular hyoscine was effective in reducing cervical ripening time when used as an adjunct to vaginal Misoprostol, with no significant adverse maternal or neonatal outcome. Funding: None declared.

RESUMO

Current scientific literature is deficient in detailing the optimal timing for conducting bariatric surgery in relation to kidney transplantation. In this study, we performed a retrospective evaluation of kidney transplant recipients with BMI >35 kg/m2. It aimed to provide data on those who received both sleeve gastrectomy (SG) and kidney transplantation (KT) simultaneously, as well as on patients who underwent SG and KT at different times, either before or after. In addition, the acceptance levels of the bariatric surgery among different scenarios were assessed. Our findings demonstrated that combined KT and SG led to successful weight loss, in contrast to undergoing kidney transplant alone, while maintaining comparable rates of graft and patient survival. Weight loss was similar between recipients who had a combined operation and those who underwent SG following the transplant. Additionally, over a median time frame of 1.7 years, patients who underwent SG before KT exhibited a statistically significant reduction in BMI at the time of the transplant. Notably, our study highlights that patients offered the combined procedure were significantly more likely to undergo SG compared to those for whom SG was presented at a different operative time than the transplant.

RESUMO

BACKGROUND: Burns are classified according to their mechanism of injury, depth, affected body area, affected region or part of the body, and extent of the lesions. Topical insulin modulates the healing process. However, studies evaluating the effects of topical insulin treatment on burns in human patients are lacking. PURPOSE: The purpose of this study was to investigate the effects of topical insulin on healing time of second-degree burns. METHODS: In this nonrandomized clinical trial, patients with second-degree burns were allocated to a control group (CG) or an intervention group (IG) in which wounds were treated with 1% silver sulfadiazine and topical insulin, respectively. RESULTS: Healing time was significantly shorter in the IG relative to the CG (9.1 ± 1.9 days and 12.7 ± 3.3 days, respectively; P < .05). The estimated burn area was similar in both groups (CG 1.44 ± 1.0%; IG 1.42 ± 0.53%). CONCLUSION: In this study, topical insulin reduced healing time in second-degree burns. Further investigation is warranted to support wider use in clinical practice.

RESUMO

BACKGROUND: To investigate the long-term effectiveness and safety of XEN45 implant, either alone or in combination with phacoemulsification, in eyes with open-angle glaucoma (OAG). METHODS: Retrospective and single center study conducted on consecutive OAG patients who underwent a XEN45 implant between February-2017 and December-2021. The primary endpoint was the mean intraocular pressure (IOP) lowering from preoperative values. Surgical success was defined as an IOP-lowering from preoperative values ≥ 20% and an IOP absolute value between 6 and 13 mm Hg, without (Complete-success) or with (Qualified-success) antiglaucoma medications. RESULTS: A total of 158 eyes (34 (21.5%) eyes XEN-solo and 124 (78.5%) XEN + Phaco) were included. The median follow-up time was 28.5 months. In the overall study population, the mean preoperative IOP was significantly lowered from 19.4 ± 6.5 mm Hg to 12.4 ± 5.0 mm Hg. The mean preoperative (95% confidence interval) IOP was significantly lowered from 21.3 (19.3-23.2) mm Hg and 18.8 (17.7-20.0) mm Hg to 12.0 (10.4-13.6) mm Hg and 12.5 (11.6-13.5) mm Hg in the XEN-Solo and XEN + Phaco groups, respectively (p < 0.0001 each, respectively). The mean number of ocular-hypotensive medications was significantly reduced in the overall study sample (from 3.4 ± 0.9 to 0.9 ± 1.3, p < 0.0001), XEN-Solo (from 3.5 ± 1.1 to 0.6 ± 1.0, p < 0.0001, and XEN + Phaco (from 3.4 ± 1.1 to 0.9 ± 1.3, p < 0.0001) groups. Eighty-four (53.2%) eyes were categorized as success, with 49 (58.3%) classified as complete success. Eighty-one (51.3%) eyes underwent needling and 15 (9.5%) eyes required an additional surgical procedure. One (0.6%) eye had endophthalmitis. CONCLUSION: XEN implant, either alone or in combination with phacoemulsification significantly lowered IOP and reduced the need of ocular-hypotensive medication, while maintaining a good safety profile.

RESUMO

Objectives. Temporary mechanical circulatory support (TMCS) has become a component in the therapeutic strategy for treatment of cardiogenic shock as a bridge-to-decision. TMCS can facilitate recovery of cardiopulmonary function, end-organ function, and potentially reduce the surgical risk of left ventricular assist device (LVAD) implantation. Despite the improvements of hemodynamics and end-organ function, post-LVAD operative morbidity might be increased in these high-risk patients. The aim of the study was to compare outcomes after Heartmate 3 (HM3) implantation in patients with and without TMCS prior to HM3 implant. Methods. In this retrospective cohort study of all HM3 patients in the period between November 2015 and October 2021, patients with and without prior TMCS were compared. Patients' demographics, baseline clinical characteristics, laboratory tests, intraoperative variables, postoperative outcomes, and adverse events were collected from patient records. Results. The TMCS group showed an improvement in hemodynamics prior to LVAD implantation. Median TMCS duration was 19.5 (14-26) days. However, the TMCS group were more coagulopathic, had more wound infections, neurological complications, and more patients were on dialysis compared with patient without TMCS prior to HM3 implantation. Survival four years after HM3 implantation was 80 and 82% in the TMCS (N = 22) and non-TMCS group (N = 41), respectively. Conclusion. Patients on TMCS had an acceptable short and long-term survival and comparable to patients receiving HM3 without prior TMCS. However, they had a more complicated postoperative course.
