RESUMO
In the Mexican Caribbean, environmental changes, hydrometeorological events, and anthropogenic activities promote dynamism in the coastal vegetation cover associated with the dune; however, their pace and magnitude remain uncertain. Using Landsat 7 imagery, spatial and temporal changes in coastal dune vegetation were estimated for the 2011-2020 period in the Sian Ka'an Biosphere Reserve. The SAVI index revealed cover changes at different magnitudes and paces at the biannual, seasonal, and monthly timeframes. Climatic seasons had a significant influence on vegetation cover, with increases in cover during northerlies (SAVI: p = 0.000), while the topographic profile of the dune was relevant for structure. Distance-based multiple regressions and redundancy analysis showed that temperature had a significant effect (p < 0.05) on SAVI patterns, whereas precipitation showed little influence (p > 0.05). The Mann-Kendall tendency test indicated high dynamism in vegetation loss and recovery with no defined patterns, mostly associated with anthropogenic disturbance. High-density vegetation such as mangroves, palm trees, and shrubs was the most drastically affected, although a reduction in bare soil was also recorded. This study demonstrated that hydrometeorological events and climate variability in the long term have little influence on vegetation dynamism. Lastly, it was observed that anthropogenic activities promoted vegetation loss and transitions; however, the latter were also linked to recoveries in areas with pristine environments, relevant for tourism.
RESUMO
Cytomegalovirus (CMV) infection is a relevant cause of morbimortality in patients receiving allogeneic stem cell transplantation (allo-HCT). Foscarnet (FCN) is an effective drug against CMV administered intravenously and usually on an inpatient basis. The Home Care Unit (HCU) for hematologic patients at our hospital designed an at-home FCN administration model to avoid the hospitalization of patients requiring FCN treatment. This study analyzes whether the at-home administration of FCN is as safe and effective as its hospital administration. We collected and compared demographic, clinical, analytical, and economic data of patients with CMV infection post-allo-HCT who received FCN in the hospital (n = 16, 17 episodes) vs. at-home (n = 67, 88 episodes). The proportions of patients with cured CMV infections were comparable between the two groups (65.9% vs. 76.5%, p = 0.395). The median duration of FCN treatment was 15 (interquartile range [IQR] 9-23) and 14 (IQR 11-19) days in the HCU and inpatient cohorts, respectively (p = 0.692). There were no significant differences in the FCN toxicities between groups except for hypocalcemia (26.1% vs. 58.8%, p = 0.007), which was more prevalent in the inpatient cohort. A significant cost-effectiveness was found in the HCU cohort, with a median savings per episode of EUR 5270. It may be concluded that home administration of FCN is a safe, effective, and cost-efficient therapeutic option for patients with CMV infection and disease.
RESUMO
OBJECTIVE: Lung Cancer (LC) in Puerto Rico (PR) is the fifth most common malignancy (5.2%), the third most common among men (5.9%) and the fifth among women (4.6%), with a mortality of 11.3%. Despite current data demonstrating the importance and clinical value for lung cancer screening LDCT Screening among high risk patients remains low regardless of the potential to prevent thousands of lung cancer deaths per year. Due to significant disparities in health care in PR it is believed that LDCT use for lung cancer screening in PR is not been enforced in the private sector. METHODS: A self-administered anonymous survey was provided to a group of pulmonologists at the annual meeting of the PR Pneumology Society. The survey contained questions regarding characteristics of their practice and implementation of lung cancer screening. Provided information was tabulated in percentages. RESULTS: A total of 31 pulmonologists participated in the administration of the survey. Most participants had their medical practice in the metropolitan area (52%), which is the most populated area with best access to physicians and health care services. The sample from the north area comprised 19% of the subjects. All respondents were affiliated to health care institutions. As most of them served 1-3 health care centers (96%) with access to specialized equipment such as Chest CT. Most of the physicians (99%) had availability of chest CT scan within 1 hour from their practices and 97% were aware of the U.S. Preventive Services Task Force lung cancer screening recommendations. Their age range was 41 and over (55%). Despite the above there were discrepancies when asked about lung cancer screening implementation. Sixteen (16) percent did not perform lung cancer screening at all, and 77% that performed screening, reported limitations to it. CONCLUSION: This data suggests that although lung cancer screening has shown to reduce mortality and is recommended by the USPTF, it is not been conducted appropriately in PR. The main limitation identified was what the health insurance had to offer rather than lack of health insurance. Other factor to take in consideration is the lack of a comprehensive screening program for Lung Cancer anywhere in the island. In addition, costs associated with staff and implementation were noted as a significant barrier among the surveyed pulmonologists.

Background: To evaluate whether EQD2(α/ß = 3Gy) at 2 cm3 of the most exposed area of the vagina is related to late vaginal toxicity in postoperative endometrial cancer (PEC) patients (p) treated with exclusive brachytherapy (BT). Methods: From 2014 to 2017, 43p were included in this study. BT was administered: 3-fractions of 6Gy in 37p and 2-fractions of 7.5Gy in 6p. The dose was prescribed at a depth of 5 mm from the applicator surface with dose-point optimization based on distance. The active treatment length was 2.5 cm. CTV-D90 and the dose to the most exposed 2 cm3 of the vagina was calculated for each patient. Late toxicity of the bladder and rectum was assessed using Radiation Therapy Oncology Group (RTOG) criteria, and vaginal toxicity by objective Late Effects Normal Tissue Task Force (LENT)-Subjective, Objective, Management, Analytic (SOMA) (LENT-SOMA) criteria. Statistics: frequency tables, mean, median, range, standard deviation, and box plot. Results: The median follow-up was 51 months (12-68). 20 p (46.5%) and 2 p (4.7%) developed G1 and G2 vaginal complications, respectively. Only 1/2 p-G2 receiving EQD2(α/ß = 3Gy) at 2 cm3 >68Gy presented vaginal shortening and 18/20 p-G1 received doses < 68Gy. Conclusions: PECp receiving exclusive brachytherapy with doses < 68Gy EQD2(α/ß = 3Gy) at 2 cm2 of the vagina presented only G0-G1 vaginal toxicity, except for one with bleeding telangiectasias. Larger prospective studies are necessary to confirm the present results.
RESUMO
Purpose: Dental hygiene graduates often experience significant psychological stress while transitioning from the educational setting to clinical practice environments. The purpose of this study was to characterize the duration of dental hygiene activities and tasks and explore efficiency within appointments, by students in educational programs.Methods: Right-handed female dental hygiene students were recruited from two dental hygiene education programs. Each participant was video recorded while providing patient care during 3 sessions, once per term, over 3 consecutive terms. Activities, tasks, and student postures and positions were coded across the patient visit. Descriptive analyses were conducted to characterize overall durations and distributions across each category. Time spent on non-dental hygiene related activities was compared to other durations, as well as across the education/training time points and by patient type.Results: Fifty-three videos were analyzed from nineteen participants. The average patient visit length was 155.06 ± 35.63 minutes; approximately half the visit was dedicated to instrumentation activities. Nearly 20% of the visit was categorized as activities or tasks unrelated to education or patient care. Although most participants completed the patient visit more quickly by the third time point, the percentage of non-dental hygiene activities did not decrease, and there were no associations between patient category type and the duration of the patient visit.Conclusion: Patient visits were roughly three times the length of the typical dental hygiene care appointment, indicating a disconnect between training and practice. In addition to spending more time on hand scaling tasks, participants spent a lot of time on equipment setup and interacting with or waiting for faculty members. These findings have implications for improving efficiency in educational settings, particularly to facilitate a successful transition to clinical practice.

AIM: To analyse the possible relationship between the EQD2(α/ß=3Gy) at 2 cm3 of the vagina and late toxicity in vaginal-cuff-brachytherapy (VBT) after external-beam-irradiation (EBRT) for postoperative endometrial carcinoma (EC). MATERIALS AND METHODS: From 2014 to 2016, 62 postoperative EC patients were treated with EBRT + VBT. The median EBRT dose was 45 Gy (44 Gy-50.4 Gy). VBT involved a single 7 Gy dose. Toxicity was prospectively evaluated using the RTOG score for the rectum and bladder and the objective LENT-SOMA criteria for the vagina. EQD2(α/ß = 3Gy) at 2 cm3 of the most exposed part of the vagina was calculated by the sum of the EBRT + VBT dose. Statistics: Boxplot, Student's t and Chi-square tests and ROC curves. RESULTS: Mean follow-up: 39.2 months (15-68). Late toxicity: bladder:0 patient; rectum:2 patients-G1; Vagina: 26 patients-17G1, 9G2; median EQD2(α/ß=3Gy) at 2 cm3 in G0-G1 patients was 70.4 Gy(SD2.36), being 72.5 Gy(SD2.94) for G2p. The boxplot suggested a cut-point identifying the absence of G2: 100 % of G2p received >68 Gy, ROC curves showed an area under the curve of 0.72 (sensitivity of 1 and specificity of 0.15). CONCLUSIONS: Doses >68 Gy EQD2(α/ß=3Gy) at 2 cm3 to the most exposed area of the vagina were associated with late G2 vaginal toxicity in postoperative EC patients treated with EBRT + VBT suggesting a very good dose limit to eliminate the risk of G2 late toxicity. The specificity obtained indicates the need for prospective analyses.
RESUMO
In 2015, we implemented an at-home allogeneic haematopoietic cell transplant (allo-HCT) program. Between 2015 and 2018, 252 patients underwent allo-HCT; 41 patients underwent allo-HCT in the at-home program (46% myeloablative; 63% unrelated donor; 32% posttransplant cyclophosphamide), and these patients were compared with 39 in-patients; safety, capacity to release beds for other programs, and economic efficiency cost were evaluated. We observed a lower incidence of febrile neutropenia in the at-home group compared with that in the in-patient group (32% versus 90%; p < 0.0001), whereas the incidence of aspergillosis was similar among groups (at-home 1% versus in-patient 3%; p = 0.5). The at-home patients showed a lower incidence of 1-year severe graft-versus-host disease (GVHD; 10% versus 29%; p = 0.03). There were no differences in 1-year transplant-related mortality, relapse, or overall survival among groups. The re-admission rate in the at-home group was 7%. The at-home setting was less expensive (9087 /transplant), and its implementation increased capacity by 10.5 allo-HCTs/year. Moreover, a chimeric antigen receptor T-cell program could be established without increasing beds. Thus, our at-home allo-HCT program may be a safe modality to reduce febrile neutropenia and acute GVHD, resulting in lower re-admission rates.

PURPOSE: The purpose of this study was to analyze the direct economic impact of two vaginal cuff brachytherapy (VBT) schedules in postoperative endometrial carcinoma (PEC) with similar vaginal control and toxicity results. MATERIALS AND METHODS: From 2006 to 2015, 397 PEC patients (p) were treated with VBT: mean 40p/year, 67.5% received external beam radiotherapy (EBRT)+VBT and 32.5% exclusive VBT. Schedule 1: 3 fractions (Fr) after EBRT and 6Fr (4-6 Gy/Fr) in exclusive VBT. Schedule 2: 7Gy × 1Fr + EBRT and 6Gy × 3Fr in exclusive VBT. Differential cost analysis of the two schedules was retrospectively performed. The direct costs in each schedule were (1) Personnel: radiotherapy technicians, nurses, radiation oncologists, medical physicists, administrative personnel, orderlies; time dedicated by each professional during CT planning acquisitions and delineation of vagina/organs at risk, dosimetric study and evaluation, autoradiography, procedure reporting time during/after treatment, removal of bladder/rectal tubes and applicators, material cleaning and transportation for sterilization; (2) Health care material (gels, gauzes, gloves, etc); (3) Equipment (time equipment used). The differential between the two schedules was estimated. Indirect costs and evaluation of quality of life-adjusted costs were not considered. RESULTS: The overall reduction in the number of Fr per year in Schedule 2 was 93. Cost savings included treatment time per year: 4,185 min (70 h); personnel: 221 ($246)/p in EBRT + VBT and 331 ($368)/p in exclusive VBT; and health care material and equipment: 40 ($44.5)/p in EBRT + VBT and 90 ($100.2)/p in exclusive VBT. The overall savings per patient was 261 ($295) in combined treatment and 421 ($475.7) in exclusive VBT. The total savings per year with Schedule 2 in 40p was 12,503 ($13,915.8). CONCLUSIONS: A 41% reduction in the fractions number in VBT for PEC allowed economic savings of 261 ($290.5)/p in combined treatment and 421 ($475.7)/p in exclusive VBT. Other benefits include patient comfort and fewer treatment visits.

The gold-standard periodontal probe is an aging tool that can detect periodontitis and monitor gingival health but is highly error-prone, does not fully characterize the periodontal pocket, and causes pain. Photoacoustic imaging is a noninvasive technique that can address these limitations. Here, a range of ultrasound frequencies between 16-40 MHz were used to image the periodontium and a contrast medium based on cuttlefish ink was used to label the pockets. A 40 MHz ultrasound frequency could spatially resolve the periodontal anatomy, including tooth, gum, gingival margin, and gingival thickness of tooth numbers 7-10 and 22-27. The photoacoustic-ultrasound measurements were more precise (0.01 mm) than those taken with physical probes by a dental hygienist. Furthermore, the full geometry of the pockets could be visualized with relative standard deviations of 10% (n = 5). This study shows the potential for non-invasive monitoring of periodontal health with photoacoustic-ultrasound imaging in the dental clinic.
RESUMO
PURPOSE: To evaluate if the dose equivalent to 2 Gy per fraction (EQD2)(α/ß=3Gy) at 0.1 cm3, 1 cm3, and 2 cm3 of vagina in vaginal-cuff-brachytherapy (VBT) (high-dose-rate [HDR] 192Ir-source) ± external-beam-irradiation (EBRT) is associated with toxicity in post-operative endometrial carcinoma (P-EC). MATERIAL AND METHODS: From June 2014 till November 2015, 67 consecutive P-EC patients underwent VBT ± EBRT; 44 patients received EBRT (median, 45 Gy; range, 44-50.4) + VBT (7 Gy), and 23 exclusive-VBT (6 Gy x 3 fractions). The upper 2.5 cm of vagina was delineated on computed tomography (CT). The active-length source was 2.5 cm, and the brachytherapy dose was prescribed at 5 mm from the applicator. D90, V100, and EQD2(α/ß=3Gy) at 0.1 cm3, 1 cm3, and 2 cm3 of the most exposed part of the vagina were calculated. Vaginal toxicity assessment was completed with a LENT-SOMA-objective-criteria. Statistics were done with the use of χ2 and Student's-t test. RESULTS: The mean follow-up was 23.2 months (7.6-46.8). Median D90 was 7.8 Gy(α/ß=3Gy). Late toxicity: 8 G1 and 9 G2. Median EQD2(α/ß=3Gy) in vagina was 88.6 Gy (62.8-177.6) for 0.1 cm3, 72.4 Gy (57.1-130.4) for 1 cm3, and 69 Gy (53-113.4) for 2 cm3. Exclusive VBT vs. EBRT+VBT showed no differences in vaginal toxicity. There was no relationship between EQD2(α/ß=3Gy) at 0.1 cm3 and 1 cm3 of vagina with G1-G2 toxicity (p = 0.62 and p = 0.58, respectively). G2 toxicity was related to EQD2(α/ß=3Gy) at 2 cm3 (p = 0.03). EQD2(α/ß=3Gy) > 68 Gy caused G2 late toxicity in 20.5% patients. All patients presenting G2 toxicity received > 68 Gy EQD2(α/ß=3Gy). CONCLUSIONS: More than 68 Gy EQD2(α/ß=3Gy) at 2 cm3 was related to G2 toxicity in P-EC-VBT. Further studies including larger number of patients are needed to confirm these results. Patients receiving these doses should be informed of the risk of toxicity, with individualized treatment planning and follow-up to reduce G2 toxicity.
RESUMO
Although purulent pericarditis is rare, it is essential to recognize its clinical features due to the high mortality rate in patients with a missed diagnosis.
RESUMO
PURPOSE: To compare vaginal control and treatment toxicity of three different high-dose-rate brachytherapy schedules as exclusive treatment in postoperative endometrial carcinoma. METHODS AND MATERIALS: From 2003 to 2015, three different schedules were used as postoperative treatment for 146 patients (p) with intermediate-risk endometrial carcinoma. Group 1 (41 p): six fractions of 4-6 Gy, 3-4 fractions per week; Group 2 (59 p): four fractions of 5-6 Gy administered daily; Group 3 (46 p): 6 Gy × 3 fractions in three consecutive days. The dose was prescribed at 5 mm of applicator surface using an active treatment length of 2.5 cm. Toxicity scores were evaluated using the Radiation Therapy Oncology Group scores for bladder and rectum and the objective criteria of late effects of normal tissues-subjective, objective, management, analytic for vagina. Statistics used were group descriptions calculating their means, medians, and ranges. Bivariate analysis was evaluated using variance models and χ2 tests. RESULTS: The mean followup was as follows: Group 1: 88 months, Group 2: 75 months, and 41 months in Group 3. No vaginal relapses were found. Late toxicity ≥ G2: rectum: 0 p in the three groups (0%). Bladder: Group 1: 1 p (2.4%), Group 2: 0%, and Group 3: 0%. Vagina: Group 1: 4 p (9.5%); Group 2: 9 p (15.3%); and Group 3:10 p (21.8%). There were no differences in late toxicity among the three groups of patients for rectum (p = 0.83), bladder (p = 0.58), and vagina (p = 0.67); the expected global risk of complications for rectum, bladder, and vagina is 0.8%, 0.8%, and 28.8%, respectively. CONCLUSIONS: Similar results in vaginal control and complications were achieved with the three schedules. The use of three fractions of 6 Gy administered daily is the best option for patient comfort and convenience and use of resources. Nonetheless, specific studies are needed to demonstrate the best cost-efficacy regime.

PURPOSE: To evaluate the preliminary results of vaginal-cuff relapses (VCR) and complications of a short brachytherapy (BT) schedule in postoperative endometrial carcinoma. METHODS AND MATERIALS: From September 2011 to December 2014, 102 patients were treated with postoperative BT for endometrial carcinoma. Seventy-four patients received a single 7 Gy dose after external beam irradiation (Group 1), and 28 intermediate-risk patients received three daily fractions of 6 Gy (Group 2). The dose was prescribed at 5 mm from the applicator surface. Toxicity was prospectively evaluated after the objective late effects of normal tissues-subjective, objective, management, analytic scores for vagina and RTOG scores for rectum and bladder. STATISTICS: χ2 and Student's t tests. RESULTS: The mean followup was 28.85 months (9.6-58.5) in Group 1 and 31.19 months (7.7-62.3) in Group 2. No VCR was found during followup. Late toxicity: vagina toxicity was developed in 24.32% of the patients in Group 1 (G1-G2) and in 21.4% in Group 2 (G1-G2 but 1 G3). Rectal toxicity appeared in only 2.7% of patients in Group 1 (G1). Neither Group 1 nor Group 2 presented late bladder toxicity. No differences were found in late toxicity between Groups 1 and 2. CONCLUSIONS: The present short BT schedule was safe in relation to VCR and late toxicity for the followup period studied. These results are similar to those of two larger previous schedules performed in our center in relation to the same point of followup.

Within the context of anthropogenic climate change, but also considering the Earth's natural climate variability, this paper explores the speculative possibility of large-scale active control of the Earth's radiative forcing. In particular, the paper revisits the concept of deploying a large sunshade or occulting disk at a static position near the Sun-Earth L1 Lagrange equilibrium point. Among the solar radiation management methods that have been proposed thus far, space-based concepts are generally seen as the least timely, albeit also as one of the most efficient. Large occulting structures could potentially offset all of the global mean temperature increase due to greenhouse gas emissions. This paper investigates optimal configurations of orbiting occulting disks that not only offset a global temperature increase, but also mitigate regional differences such as latitudinal and seasonal difference of monthly mean temperature. A globally resolved energy balance model is used to provide insights into the coupling between the motion of the occulting disks and the Earth's climate. This allows us to revise previous studies, but also, for the first time, to search for families of orbits that improve the efficiency of occulting disks at offsetting climate change on both global and regional scales. Although natural orbits exist near the L1 equilibrium point, their period does not match that required for geoengineering purposes, thus forced orbits were designed that require small changes to the disk attitude in order to control its motion. Finally, configurations of two occulting disks are presented which provide the same shading area as previously published studies, but achieve reductions of residual latitudinal and seasonal temperature changes.

Migration is a channel through which Chagas disease is imported, and vertical transmission is a channel through which the disease is spread in non-endemic countries. This study presents the economic evaluation of Chagas disease screening in pregnant women from Latin America and in their newborns in a non endemic area such as Spain. The economic impact of Chagas disease screening is tested through two decision models, one for the newborn and one for the mother, against the alternative hypothesis of no screening for either the newborn or the mother. Results show that the option "no test" is dominated by the option "test". The cost effectiveness ratio in the "newborn model" was 22/QALYs gained in the case of screening and 125/QALYs gained in the case of no screening. The cost effectiveness ratio in the "mother model" was 96/QALYs gained in the case of screening and 1675/QALYs gained in the case of no screening. Probabilistic sensitivity analysis highlighted the reduction of uncertainty in the screening option. Threshold analysis assessed that even with a drop in Chagas prevalence from 3.4% to 0.9%, a drop in the probability of vertical transmission from 7.3% to 2.24% and with an increase of screening costs up to 37.5, "test" option would still be preferred to "no test". The current study proved Chagas screening of all Latin American women giving birth in Spain and of their infants to be the best strategy compared to the non-screening option and provides useful information for health policy makers in their decision making process.

En la práctica odontológica, existen numerosas intervenciones en las que se producen lesiones óseas cavitarias, bien sea como complicación de enfermedades, bien de forma y atrogénica (legrados,cirugía implantaria, etc.). Ante estas situaciones, puede ser muy útil recurrir al empleo de biomateriales, que contribuyan a una más rápida recuperación de los tejidos dañados. Con la finalidad de contribuir a sentar las bases para esta terapéutica médico-quirúrgica, se revisa el concepto de los factores de crecimiento, su utilidad en la regeneración ósea y la forma de obtenerlos (AU)
In dentistry, several surgical treatments produce some bone cavitations, sometimes as a complication and sometimes as iatrogenic lesions(after scraping, implant surgery, etc.). In front of these situations, the use of biomaterials can be helpful, in order to regenerate more rapidly the affected tissues. In this work, the concept, benefit and obtaining of growth factors is reviewed, with the aim of establishing a base line for this kind of medical-surgical treatment (AU)

Objetivo: Analizar la relación entre el grado de inflamación gingival de un grupo de pacientes trasplantados de médula ósea y el tipo de mucositis que presentan. Diseño: Se estudian 58 pacientes con enfermedad hematológica que son trasplantados de médula ósea. La población se clasifica en tres grupos: grupo A (pacientes vistos antes y después de la infusión), grupo B (pacientes explorados sólo después de la infusión) y grupo C (todos los pacientes vistos después de la infusión). Se realiza un protocolo de exploración antes, durante y después del tratamiento. Los resultados se procesan mediante el paquete estadístico SPSS+ Windows, realizándose un análisis descriptivo. Resultados: El CAOd registrado es de 10,7. El índice de sangrado antes de la infusión es del 10 por ciento, pasando al 15 por ciento post-infusión (22 por ciento si se considera el grupo C). El índice gingival pre-tratamiento es de 1,6 (grupo A), pasando a 1,3 post-trasplante y siendo de 1,9 para él grupo B. El índice de placa pasa de 1,8 a 1,4 en el grupo A y es de 2,1 en el grupo B. El 82 por ciento de los pacientes presentan mucositis de gradó II, III ó IV. La correlación entre índice gingival mayor o menor de 1,5 y grado de mucositis presentado es estadísticamente significativa, con una p<0,000.Conclusiones: La visita previa al paciente que será transplantado implica un mejor índice gingival post-trasplante. El mayor grado de inflamación gingival conlleva un mayor grado de mucositis. Es importante controlar la inflamación gingival como medida para prevenir la mucositis (AU)
