RESUMO

We generated 238 Zika virus (ZIKV) genomes from 135 persons in Brazil who had samples collected over 1 year to evaluate virus persistence. Phylogenetic inference clustered the genomes together with previously reported ZIKV strains from northern Brazil, showing that ZIKV has been remained relatively stable over time. Temporal phylogenetic analysis revealed limited within-host diversity among most ZIKV-persistent infected associated samples. However, we detected unusual virus temporal diversity from >5 persons, uncovering the existence of divergent genomes within the same patient. All those patients showed an increase in neutralizing antibody levels, followed by a decline at the convalescent phase of ZIKV infection. Of interest, in 3 of those patients, titers of neutralizing antibodies increased again after 6 months of ZIKV infection, concomitantly with real-time reverse transcription PCR re-positivity, supporting ZIKV reinfection events. Altogether, our findings provide evidence for the existence of ZIKV reinfection events.

RESUMO

PURPOSE: We evaluated the prevalence of immune-related adverse events and anti-tumor efficacy in advanced/metastatic urothelial carcinoma following immune-checkpoint inhibitors (ICIs) treatment. METHODS: We conducted a multicenter retrospective study of patients with advanced/metastatic urothelial carcinoma treated with ICIs in four Spanish institutions. irAEs were classified using Common Terminology Criteria for Adverse Event (CTCAE) v.5.0 guidelines. The primary endpoint was overall survival (OS). Other endpoints were overall response rate (ORR) and progression-free survival (PFS). irAEs were evaluated as a time-dependent covariate to avoid immortal time bias. RESULTS: A total of 114 patients were treated with ICIs between May 2013 and May 2019, 105 (92%) of whom received ICIs as monotherapy. irAEs of any grade were experienced in 56 (49%) patients and 21 (18%) patients had grade ≥ 3 toxicity. The most frequent irAEs were gastrointestinal and dermatological toxicities, reported in 25 (22%) and 20 (17%) patients, respectively. Patients with grade 1-2 irAEs had significantly longer OS compared to those without grade 1-2 irAEs (median 18.2 vs. 8.7 months, HR = 0.61 [95% CI 0.39-0.95], p = 0.03). No association with efficacy was observed for patients with grade ≥ 3 irAEs. No difference in PFS was observed after adjusting for the immortal time bias. ORR was higher in patients who developed irAEs (48% vs 17%, p < 0.001). CONCLUSIONS: Our findings suggest that development of irAEs was associated with higher ORR, and patients who developed grade 1-2 irAEs had longer OS. Prospective studies are necessary to confirm our findings.

RESUMO

Most muscle-invasive bladder cancer (BC) are urothelial carcinomas (UC) of transitional origin, although histological variants of UC have been recognized. Smoking is the most important risk factor in developed countries, and the basis for prevention. UC harbors high number of genomic aberrations that make possible targeted therapies. Based on molecular features, a consensus classification identified six different MIBC subtypes. Hematuria and irritative bladder symptoms, CT scan, cystoscopy and transurethral resection are the basis for diagnosis. Radical cystectomy with pelvic lymphadenectomy is the standard approach for muscle-invasive BC, although bladder preservation is an option for selected patients who wish to avoid or cannot tolerate surgery. Perioperative cisplatin-based neoadjuvant chemotherapy is recommended for cT2-4aN0M0 tumors, or as adjuvant in patients with pT3/4 and or pN + after radical cystectomy. Follow-up is particularly important after the availability of new salvage therapies. It should be individualized and adapted to the risk of recurrence. Cisplatin-gemcitabine is considered the standard first line for metastatic tumors. Carboplatin should replace cisplatin in cisplatin-ineligible patients. According to the EMA label, pembrolizumab or atezolizumab could be an option in cisplatin-ineligible patients with high PD-L1 expression. For patients whose disease respond or did not progress after first-line platinum chemotherapy, maintenance with avelumab prolongs survival with respect to the best supportive care. Pembrolizumab also increases survival versus vinflunine or taxanes in patients with progression after chemotherapy who have not received avelumab, as well as enfortumab vedotin in those progressing to first-line chemotherapy followed by an antiPDL1/PD1. Erdafitinib may be considered in this setting in patients with FGFR alterations. An early onset of supportive and palliative care is always strongly recommended.

RESUMO

Pediatric Intensive Care Units (PICUs) provide multidisciplinary care to critically ill children and their families. Grief is present throughout the trajectory of illness and can peak around the time of death or non-death losses. The objective of this study was to assess how PICUs around the world implement grief and bereavement care (GBC) as part of an integrated model of care. This is a multicenter cross-sectional, prospective survey study. Questionnaires with multiple-choice and open-ended questions focusing on unit infrastructure, personnel, policies, limited patient data, and practices related to GBC for families and health care professionals (HCPs) were completed by on-site researchers, who were HCPs on the direct care of patients. PICU fulfillment of GBC goals was evaluated using a custom scoring based on indicators developed by the Initiative for Pediatric Palliative Care (IPPC). We compared average total and individual items fulfillment scores according to the respective country's World Bank income. Patient characteristics and details of unit infrastructure were also evaluated as potential predictors of total GBC fulfillment scores. Statistical analysis included multilevel generalized linear models (GLM) with a Gaussian distribution adjusted by child age/gender and clustering by center, using high income countries (HICs) as the comparative reference. Additionally, we applied principals of content analysis to analyze and summarize open-ended answers to contextualize qualitative data. The study included 34 PICUs from 18 countries: high-income countries (HICs): 32.4%, upper middle-income countries (UMICs): 44.1%, low middle-income and low-income countries (LMI/LICs): 23.5%. All groups reported some compliance with GBC goals; no group reported perfect fulfillment. We found statistically significant differences in GBC fulfillment scores between HICs and UMICs (specifically, HCP grief support), and between HICs and LMICs (specifically, family grief support and HCP grief support). PICUs world-wide provide some GBC, independent of income, but barriers include lack of financial support, time, and training, overall unit culture, presence of a palliative care consultation service, and varying cultural perceptions of child death. Disparities in GBC for families and HCPs exist and were related to the native countries' income level. Identifying barriers to support families and HCPs, can lead to opportunities of improving GBC in PICUs world-wide.

RESUMO

Four formulations of an investigational tetravalent dengue purified inactivated vaccine, administered as two doses one month (M) apart, were previously shown to be immunogenic and well-tolerated up to M13 of the phase I study NCT01702857. Here, we report results of the follow-up from M14 to year (Y) 3. One hundred healthy Puerto Rican adults, predominantly dengue virus (DENV)-primed, were randomized 1:1:1:1:1 to receive placebo or vaccine formulations: 1 µg/serotype/dose adjuvanted with aluminum, AS01E or AS03B, or aluminum-adjuvanted 4 µg/serotype/dose. No serious adverse events occurred. Two medically-attended potential immune-mediated disease cases, vaccination unrelated, were reported (groups 1 µg+Alum and 1 µg+AS03B). Of 14 instances of suspected dengue, none were laboratory confirmed. Geometric mean neutralizing antibody titers against DENV 1-4 waned from M14, but remained above pre-vaccination levels for DENV 1-3, with the highest values for group 1 µg+AS03B: 1220.1, 920.5, 819.4, and 940.5 (Y2), and 1329.3, 1169.2, 1219.8, and 718.9 (Y3). All formulations appeared to be safe and immunogenic during the 3-year follow-up.

RESUMO

The safety and immunogenicity of four adjuvanted formulations of an investigational tetravalent dengue purified inactivated vaccine (DPIV) were evaluated in a predominantly dengue-primed population in Puerto Rico. In this placebo-controlled, randomized, observer-blind, phase I trial, 100 healthy adults were randomized 1:1:1:1:1 to receive DPIV at Day (D)0 and D28 (1 µg per dengue virus [DENV] type 1-4 adjuvanted with either alum, AS01E or AS03B, or 4 µg per DENV type adjuvanted with alum) or saline placebo. Functional antibody responses were assessed using a microneutralization assay at D56, Month (M)7, and M13. All DPIV formulations were well tolerated and no safety signals were identified through M13. The M13 according-to-protocol (ATP) immunogenicity cohort included 83 participants. The ATP analysis of immunogenicity was performed only on the 78 subjects seropositive for ≥ 1 DENV type at baseline: 69 tetravalent, three trivalent, two bivalent, and four monovalent. In all DPIV groups, geometric mean antibody titers (GMTs) increased from D0 to D56 and waned modestly through M13, while remaining well above prevaccination levels. The 4 µg + alum and the AS01E- and AS03B-adjuvanted formulations were highly immunogenic, with M13-neutralizing antibody GMTs against all four DENV types above 1,000. M13/D0 GMT ratios were highest in the 1 µg + AS03B group (ranging 3.2-3.7 depending on the DENV type). These results encourage continued clinical development of DPIV (ClinicalTrials.gov: NCT01702857).

RESUMO

AbstractDengue virus infections have adversely impacted U.S. military operations since the Spanish-American War. The erosion of mission capabilities and lost duty days are underestimated. Appreciating the incidence and prevalence of dengue infections in U.S. military personnel is important to inform disease prevention strategies. Banked pre- and post-deployment serum samples from 1,000 U.S. military personnel with a single deployment to a dengue-endemic region were tested using a screening microneutralization assay to detect anti-dengue-virus-neutralizing antibodies. A total of 76 (7.6%) post-deployment samples were positive and 15 of the pre-deployment samples were negative. These figures represent an infection incidence of 1.5% and total of 17.6 seroconversions per 10,000 deployment months. These data represent a deploying military population with a relatively high background rate of dengue seropositivity, a low level of infection during deployment compared with background infection rates in the local populations, and the potential for worsening clinical attack rates with increased frequency of deployment. Additional studies are required to more clearly elucidate the dengue infection and disease risk in U.S. military personnel.

RESUMO

Zika virus (ZIKV) is responsible for a major ongoing epidemic in the Americas and has been causally associated with fetal microcephaly. The development of a safe and effective ZIKV vaccine is therefore an urgent global health priority. Here we demonstrate that three different vaccine platforms protect against ZIKV challenge in rhesus monkeys. A purified inactivated virus vaccine induced ZIKV-specific neutralizing antibodies and completely protected monkeys against ZIKV strains from both Brazil and Puerto Rico. Purified immunoglobulin from vaccinated monkeys also conferred passive protection in adoptive transfer studies. A plasmid DNA vaccine and a single-shot recombinant rhesus adenovirus serotype 52 vector vaccine, both expressing ZIKV premembrane and envelope, also elicited neutralizing antibodies and completely protected monkeys against ZIKV challenge. These data support the rapid clinical development of ZIKV vaccines for humans.

RESUMO

Zika virus (ZIKV) is a flavivirus that is responsible for the current epidemic in Brazil and the Americas. ZIKV has been causally associated with fetal microcephaly, intrauterine growth restriction, and other birth defects in both humans and mice. The rapid development of a safe and effective ZIKV vaccine is a global health priority, but very little is currently known about ZIKV immunology and mechanisms of immune protection. Here we show that a single immunization with a plasmid DNA vaccine or a purified inactivated virus vaccine provides complete protection in susceptible mice against challenge with a strain of ZIKV involved in the outbreak in northeast Brazil. This ZIKV strain has recently been shown to cross the placenta and to induce fetal microcephaly and other congenital malformations in mice. We produced DNA vaccines expressing ZIKV pre-membrane and envelope (prM-Env), as well as a series of deletion mutants. The prM-Env DNA vaccine, but not the deletion mutants, afforded complete protection against ZIKV, as measured by absence of detectable viraemia following challenge, and protective efficacy correlated with Env-specific antibody titers. Adoptive transfer of purified IgG from vaccinated mice conferred passive protection, and depletion of CD4 and CD8 T lymphocytes in vaccinated mice did not abrogate this protection. These data demonstrate that protection against ZIKV challenge can be achieved by single-shot subunit and inactivated virus vaccines in mice and that Env-specific antibody titers represent key immunologic correlates of protection. Our findings suggest that the development of a ZIKV vaccine for humans is likely to be achievable.

RESUMO

This was a double-blind, randomized, controlled, phase II clinical trial, two dose study of re-derived, live-attenuated, tetravalent dengue virus (TDEN) vaccine (two formulations) or placebo in subjects 1-50 years of age. Among the 636 subjects enrolled, 331 (52%) were primed, that is, baseline seropositive to at least one dengue virus (DENV) type. Baseline seropositivity prevalence increased with age (10% [< 2 years], 26% [2-4 years], 60% [5-20 years], and 93% [21-50 years]). Safety profiles of TDEN vaccines were similar to placebo regardless of priming status. No vaccine-related serious adverse events (SAEs) were reported. Among unprimed subjects, immunogenicity (geometric mean antibody titers [GMT] and seropositivity rates) for each DENV increased substantially in both TDEN vaccine groups with at least 74.6% seropositive for four DENV types. The TDEN vaccine candidate showed an acceptable safety and immunogenicity profile in children and adults ranging from 1 to 50 years of age, regardless of priming status. ClinicalTrials.gov: NCT00468858.

RESUMO

The aim of this study was to determine the accuracy of ultrasonographic measurement of canine kidneys. A method agreement analysis comparing pairs of measurements (ultrasonographic kidney dimensions and direct kidney dimensions) was performed. Nineteen dogs aging from one to thirteen years were used. The ultrasonographic and anatomic linear parameters obtained from the kidneys were the following: width, length and height; the kidney volume was estimated from these measures using the formula of an ellipsoid. The statistical method performed (method agreement) demonstrated a satisfactory agreement. It can be concluded that ultrasound measurement is sufficiently accurate for clinical use, assuming a careful scanning technique.


El objetivo de este trabajo fue determinar la fiabilidad de las medidas ecográficas de los riñones del perro. Se llevó a cabo un análisis de concordancia entre métodos (medidas ecográficas del riñón y medidas anatómicas directas). Se utilizaron perros cuyas edades iban de uno a trece años. Las medidas ecográficas y anatómicas lineales que se obtuvieron de los riñones fueron las siguientes: anchura, longitud y altura. El volumen renal se estimó aplicando estas medidas en la fórmula de un elipsoide. A través de un análisis de concordancia estadística se observó un nivel de acuerdo satisfactorio. Se puede concluir que las medidas ecográficas son suficientemente fiables para su uso en clínica, si se lleva a cabo una cuidadosa técnica ecográfica.

RESUMO

BACKGROUND: Despite broad advances in multimodal treatment of locally advanced breast cancer (LABC), 30 to 40% of patients develop loco-regional relapse. The aim of this study was to analyze in a retrospective manner the effectiveness of concurrent chemo-radiotherapy (CCRTh) after neoadjuvant chemotherapy (NCT) in patients with LABC. METHODS: One hundred twelve patients with LABC (stage IIB-IIIB) were treated with NCT (5-fluorouracil 500 mg/m2, doxorubicin 50 mg/m2, and cyclophosphamide 500 mg/m2 (FAC), or doxorubicin 50 mg/m2 and cyclophosphamide 500 mg/m2 (AC) IV in four 21-day courses) followed by CCRTh (60 Gy breast irradiation and weekly mitomycin 5 mg/m2, 5-fluorouracil 500 mg/m2, and dexamethasone 16 mg, or cisplatin 30 mg/m2, gemcitabine 100 mg/m2 and dexamethasone 16 mg), and 6-8 weeks later, surgery and two additional courses of FAC, AC, or paclitaxel 90 mg/m2 weekly for 12 weeks, and in case of estrogen-receptor positive patients, hormonal therapy. RESULTS: Stages IIB, IIIA and -B were 21.4, 42.9, and 35.7%, respectively. Pathological complete response (pCR) in the breast was 42% (95% CI, 33.2-50.5%) and, 29.5% (95% CI, 21.4-37.5%) if including both the breast and the axillary nodes. Multivariate analysis showed that the main determinant of pCR was negative estrogen-receptor status (HR=3.8; 95% CI, 1.5-9; p=0.016). The 5-year disease-free survival (DFS) was 76.9% (95% CI, 68.2-84.7%). No relationship between pCR and DFS was found. Multivariate analysis demonstrated that the main DFS determinant was clinical stage (IIB and IIIA vs. IIIB, HR=3.1; 95% CI, 1.02-9.74; p=0.04). Only one patient had local recurrence. Five-year overall survival was 84.2% (95% CI, 75-93.2%). The toxicity profile was acceptable. CONCLUSION: This non-conventional multimodal treatment has good loco-regional control for LABC. Randomized clinical trials of preoperative CCRTh following chemotherapy, in patients with LABC are warranted.

RESUMO

BACKGROUND: Despite recent efforts to improve medical treatment for injured bullfighters, including the foundation of a scientific society for bullfight injuries, serious injuries, in particular in villages and smaller arenas, still do occur. We are not aware of any series in the English literature that aimed to study the specific mechanisms, types, and outcomes of these injuries. METHODS: A review of the trauma registry of injured bullfighters who suffered any type of trauma during bullfighting and received emergency therapy by the Surgical Trauma Services between 1994 and 2004 at the Plaza de Toros Nuevo Progreso, Guadalajara, Mexico. RESULTS: In all, 68 out of 750 bullfighters (9.06%) required emergency assistance during bullfighting. Trauma to the upper and lower extremity was most common (66%), followed by injuries to the inguinal (8%) and perineal area (7%). Extremity injuries included penetrating wounds requiring operative debridement in 64% of cases, articular dislocations in 4%, closed fractures in 4%, and open fractures in 1% of cases. Major vascular injuries occurred in 5% of the cases. Penetrating inguinal and penetrating perineal injuries were associated with major vascular injuries to the femoral vessels, necessitating operative repair in 33% of the cases. CONCLUSION: A considerable risk of serious, life-threatening injuries is inherent to bullfighting. Penetrating inguinal and perineal trauma with injury to the femoral vessels represents a specific, potentially fatal injury. A low threshold for exploration of these penetrating injuries in injured bullfighters is associated with a favorable outcome. Appreciation of the unique mechanisms and types of injuries related to bullfighting should lead to target intervention and help the evolvement of improved emergency treatment in organized bullfighting.

RESUMO

Antecedentes: las obstrucciones de la vía biliar en general son provocadas por cálculos y neoplasias. Existen otras alteraciones mucho menos frecuentes que pueden provocar obstrucción, entre ellas se encuentran los hamartomas de la vía biliar. Se presenta el caso de una paciente de 34 años diabética, que inicia su padecimiento con dolor abdominal e ictericia. El estudio inicia con ultrasonido de vesícula y vías biliares, que reporta colelitiasis y dilatación de vías biliares. Se realiza CPRE y se descubre una lesión ocupativa del árbol biliar. Se somete a colecistectomía y exploración de la vía biliar. La evolución de la paciente fue satisfactoria. La revisión de patología reporta un hamartoma de la vía biliar extrahepática. Los hamartomas de la vía biliar son neoplasias benignas poco frecuentes, sin embargo, debemos de tenerlas en mente como parte del diagnóstico diferencial.
