Frequency of same-day contraceptive initiation, recent unprotected intercourse, and pregnancy risk: a prospective cohort study of multiple contraceptive methods.

BACKGROUND: Same-day start removes barriers to contraceptive initiation and may reduce the risk of unintended pregnancy. It may be appropriate for all contraceptive methods, but we lack data comparing methods. OBJECTIVE: This study aimed to assess the frequency of same-day start with 6 contraceptive methods among new contraceptive users and describe the efficacy of same-day start in terms of first-cycle pregnancy risk overall and by each method. STUDY DESIGN: Using prospective data from the HER Salt Lake Contraceptive Initiative, we identified and assessed outcomes for participants initiating a new method of contraception beyond the first 7 days of their menstrual cycle (same-day start). Enrolled participants at 4 family planning clinics in Salt Lake County, Utah between September 2015 and March 2017 received their method of choice regardless of their cycle day or recent unprotected intercourse. All participants self-reported last menstrual period data and unprotected intercourse events in the previous 2 weeks. We excluded participants who received care immediately after or within 2 weeks of abortion care. Clinical electronic health records provided information on contraceptive method initiation and use of oral emergency contraception. Participants reported pregnancy outcomes in 1-, 3-, and 6-month follow-up surveys with clinic verification to identify any pregnancy resulting from same-day initiation. The primary outcomes report the frequency of same-day start use and first-cycle pregnancy risk among same-day start users of all contraceptive methods. The secondary outcomes include frequency of and pregnancy risk in the first cycle of use among same-day start contraception users by method. We also report the frequency of unprotected intercourse within 5 days and 6 to 14 days of contraception initiation, frequency of concomitant receipt of oral emergency contraception with initiation of ongoing contraception, and pregnancy risk with these exposures. We analyzed pregnancy risk for each contraceptive method initiated on the same day and assessed the simultaneous use of oral emergency contraception. RESULTS: Of the 3568 individuals enrolled, we identified most as same-day start users (n=2575/3568; 72.2%), with 1 in 8 of those reporting unprotected intercourse in the previous 5 days (n=322/2575; 12.5%) and 1 in 10 reporting unprotected intercourse 6 to 14 days before contraceptive method initiation (n=254/2575; 9.9%). We identified 11 pregnancies among same-day start users (0.4%; 95% confidence interval, 0.2-0.7), as opposed to 1 (0.1%; 95% confidence interval, 0.002-0.6) among those who initiated contraception within 7 days from the last menstrual period. Users of oral hormonal contraception and vaginal hormonal methods reported the highest first-cycle pregnancy rates (1.0-1.2). Among same-day start users, 174 (6.8%) received oral emergency contraception at enrollment in conjunction with another method. Among the same-day start users who received emergency contraception at initiation, 4 (2.3%) pregnancies were reported. CONCLUSION: Same-day start is common and associated with a low pregnancy risk. Using the "any method, any-time" approach better meets contraceptive clients' needs and maintains a low risk of pregnancy.

Comprehensive NGS profiling to enable detection of ALK gene rearrangements and MET amplifications in non-small cell lung cancer.

Introduction: Next-generation sequencing (NGS) is currently widely used for biomarker studies and molecular profiling to identify concurrent alterations that can lead to the better characterization of a tumor's molecular landscape. However, further evaluation of technical aspects related to the detection of gene rearrangements and copy number alterations is warranted. Methods: There were 12 ALK rearrangement-positive tumor specimens from patients with non-small cell lung cancer (NSCLC) previously detected via fluorescence in situ hybridization (FISH), immunohistochemistry (IHC), and an RNA-based NGS assay, and 26 MET high gene copy number (GCN) cases detected by FISH, selected for this retrospective study. All 38 pre-characterized cases were reassessed utilizing the PGDx™ elio™ tissue complete assay, a 505 gene targeted NGS panel, to evaluate concordance with these conventional diagnostic techniques. Results: The detection of ALK rearrangements using the DNA-based NGS assay demonstrated excellent sensitivity with the added benefit of characterizing gene fusion partners and genomic breakpoints. MET copy number alterations were also detected; however, some discordances were observed likely attributed to differences in algorithm, reporting thresholds and gene copy number state. TMB was also assessed by the assay and correlated to the presence of NSCLC driver alterations and was found to be significantly lower in cases with NGS-confirmed canonical driver mutations compared with those without (p=0.0019). Discussion: Overall, this study validates NGS as an accurate approach for detecting structural variants while also highlighting the need for further optimization to enable harmonization across methodologies for amplifications.

Socket shield technique: Stress distribution analysis.

Background: To analyze through finite element analysis the stress distribution in peri-implant bone tissues, implants, and prosthetic components induced by the socket shield (SS) technique in comparison to other techniques used to treat tooth loss. Materials and Methods: A three-dimensional model of a superior central incisor crown supported by implant was modeled and three different placement conditions were simulated: SS - 2.0-mm-thick root dentin fragment positioned between the alveolar buccal wall and implant; heterologous bone graft (HBG) - bovine bone graft positioned the alveolar buccal wall and implant; and control (C) - implant fully placed in bone tissue of a healed alveolus. The model was restricted at the lateral surfaces of the bone tissue and the following loads were simulated: Both oblique (45°) loads of 100 N on the lingual surface of the crown (maximal habitual intercuspation) and 25.5 N on the incisal edge of the crown (tooth contact during mandibular protrusion) were simultaneously applied. Tensile stress, shear stress, compression, and displacement were analyzed in the cortical bone, trabecular bone, dentin root fragment, and bone graft; while equivalent von Mises stresses were quantified in the implant and prosthetic components. Results: Stress values of SS and HBG in the bone tissues were higher than C, while slight differences within models were observed for dentin root fragment, bone graft, implant, and prosthetic components. Conclusions: The SS technique presented the highest stress concentration in the peri-implant tissues.

Clinical characterization of human bocavirus 1 infection in infants hospitalized in an intensive care unit for severe acute respiratory tract disease.

Acute respiratory infections represent the leading cause of morbimortality in children and viruses are the main etiological agents. Here we describe the clinical characteristics and evolution of infants admitted to intensive care unit with severe acute respiratory infection (SARI) due to Human Bocavirus 1 mono-infection in patients without previous comorbidity. We also compared them with respiratory syncytial virus (RSV) cases. Of 141 cases included (age 5.43 ± 4.54 months, 52% male), 80% had at least 1 virus detected. RSV was the most frequent in the series (71.6%) followed by HBoV1 (28%). Five cases of HBoV1 mono-detection were identified. Pediatric acute respiratory distress syndrome was present in both groups, HBoV1 and RSV. The clinical presentation and evolution of HBoV1 single infection was similar to RSV. HBoV1 should be included among the agents investigated in cases of SARI in infants.

The effect of the die material used in the indirect technique on the fracture resistance of a restored molar.

The aim of this study was to evaluate the effect of different die materials used in the indirect resin composite restorative technique on the fracture resistance and failure mode of restored molars and compare it with the direct resin composite restorative technique. Two flexible die silicone materials for dental models (Die Silicone - Voco and Scan die - Yller) and a type IV dental stone material (Fujirock EP - GC) were evaluated. Sixty third molars were selected and divided into four groups: indirect resin composite restoration - Die silicone (IRCR-DS); indirect resin composite restoration - Scan die (IRCR-SD); indirect resin composite restoration - Fujirock EP (IRCR-FR), and direct resin composite restoration (DRCR). Class II MOD cavities were prepared with 5 mm of buccolingual width and depth. The specimens were restored and subjected to an axial compression load until fracture, and the data were analyzed by one-way ANOVA and Tukey's HSD test (α=.05). The fracture mode was classified into restorable and unrestorable fractures. Fracture resistance values were influenced by the die material used for the IRCR fabrication and by the restorative technique (p<.001). Fracture resistance mean values and standard deviation were: IRCR-DS: 1835.5 ± 324.0 A; IRCR-SD: 1732.5 ± 384.1 AB; IRCR-FR: 1419.3 ± 318.8 BC; and DRCR: 1100.6 ± 224.9 C. Restorable fracture was more prevalent. IRCR with flexible die casts promoted higher fracture resistance and lower prevalence of unrestorable fractures.

Evaluation of the host immune response assay SeptiCyte RAPID for potential triage of COVID-19 patients.

Tools for the evaluation of COVID-19 severity would help clinicians with triage decisions, especially the decision whether to admit to ICU. The aim of this study was to evaluate SeptiCyte RAPID, a host immune response assay (Immunexpress, Seattle USA) as a triaging tool for COVID-19 patients requiring hospitalization and potentially ICU care. SeptiCyte RAPID employs a host gene expression signature consisting of the ratio of expression levels of two immune related mRNAs, PLA2G7 and PLAC8, measured from whole blood samples. Blood samples from 146 adult SARS-CoV-2 (+) patients were collected within 48 h of hospital admission in PAXgene blood RNA tubes at Hospital del Mar, Barcelona, Spain, between July 28th and December 1st, 2020. Data on demographics, vital signs, clinical chemistry parameters, radiology, interventions, and SeptiCyte RAPID were collected and analyzed with bioinformatics methods. The performance of SeptiCyte RAPID for COVID-19 severity assessment and ICU admission was evaluated, relative to the comparator of retrospective clinical assessment by the Hospital del Mar clinical care team. In conclusion, SeptiCyte RAPID was able to stratify COVID-19 cases according to clinical severity: critical vs. mild (AUC = 0.93, p < 0.0001), critical vs. moderate (AUC = 0.77, p = 0.002), severe vs. mild (AUC = 0.85, p = 0.0003), severe vs. moderate (AUC = 0.63, p = 0.05). This discrimination was significantly better (by AUC or p-value) than could be achieved by CRP, lactate, creatine, IL-6, or D-dimer. Some of the critical or severe cases had "early" blood draws (before ICU admission; n = 33). For these cases, when compared to moderate and mild cases not in ICU (n = 37), SeptiCyte RAPID had AUC = 0.78 (p = 0.00012). In conclusion, SeptiCyte RAPID was able to stratify COVID-19 cases according to clinical severity as defined by the WHO COVID-19 Clinical Management Living Guidance of January 25th, 2021. Measurements taken early (before a patient is considered for ICU admission) suggest that high SeptiScores could aid in predicting the need for later ICU admission.

The parental psychological distress caused by separation from their critically ill child during the COVID-19 pandemic: A tale of two cities.

Introduction: A child's critical illness is a stressful event for the entire family, causing significant emotional distress among parents and changes to family functioning. The Severe Acute Respiratory Syndrome-Related Coronavirus 2 (SARS-CoV-2) pandemic has abruptly caused modifications in visitation policies of Pediatric Intensive Care Units (PICUs) in many countries. We hypothesized that caregivers with no or severely restricted access to PICUs would demonstrate increased psychological distress as compared to those who had limitless access (LA) to PICUs. Methods: Sociodemographic variables, levels of psychological distress, ratings of family functioning, and ability to cope with stressful events were collected with an online survey in a group of caregivers after their child's hospitalization. Ratings of psychological distress were compared between caregivers with no/severely restricted (NA) and with LA to PICUs. Results: Measures of depression, anxiety, and global severity index (GSI) of psychological distress were significantly higher in NA caregivers as compared to LA. Among demographic characteristics of the sample, only gender influenced the severity of psychological symptoms: women showed an increased score on levels of somatization, depression, anxiety, and GSI. Avoidant coping style positively correlated with measures of depression. Univariate General Linear Model (GLM) analyses of the effects of sex, age, visitation policies of PICUs, and score of avoidant coping strategies on measures of psychological distress confirmed a significant univariate effect of no access to PICUs on parents' psychopathological scores. Conclusion: Restrictions imposed on visitation policies in PICU during the pandemic negatively impacted families' psychological wellbeing. A balance between the safety of patients, families, and health care professionals and meeting the needs of families is of utmost importance.

Outpatient Opioid and Naloxone Prescribing Practices at an Academic Medical Center during the COVID-19 Pandemic.

While improving opioid safety has been a national priority, the coronavirus disease 2019 (COVID-19) pandemic has been associated with increased rates of opioid overdose. The present study characterized outpatient opioid and naloxone prescribing patterns during the COVID-19 pandemic. A retrospective chart review was conducted of adult patients receiving opioid therapy between August 2020 through October 2020 from outpatient clinics within a Texas health system. The primary outcome was naloxone co-prescription during the study period or within the year prior. During the study period, 1,368 patients received an opioid prescription, most of which were prescribed for chronic pain treatment (63.0%). Most opioid prescriptions (91.5%) were written for < 50 MME/day. For prescriptions written for acute pain, 78% were written for ≤ 10 days supply. While 31.1% of patients received gabapentinoid prescriptions, few (7.9%) received benzodiazepine or Z-hypnotic prescriptions. Twenty-two (1.6%) patients were co-prescribed naloxone. In this study, naloxone was rarely prescribed for outpatients receiving opioid prescriptions during the COVID-19 pandemic. Health systems should continue to prioritize adherence to evidence-based clinical guidelines and increase access to naloxone.

Efficacy of two low-level laser therapy protocols following lower third molar surgery - a randomized, double-blind, controlled clinical trial.

The aim of this study was to test two low-level laser therapy protocols by evaluating pain control, swelling and trismus in the postoperative period of lower third molar surgeries. This was a randomized, double-blind, placebo-controlled, crossover trial. Patients presenting two symmetrically impacted mandibular third molars were included. One side was randomly assigned for LLLT applied immediately after surgery (T1) and then after 24 (T2) and 48 hours (T3) (Protocol A). The other side received LLLT applied immediately after surgery and placebo after 24 and 48 hours (Protocol B). LLLT was given by intraoral application (660nm, 5 J/cm2, 10 s, 20 mW, 4 points) followed by extraoral application (789 nm, 30 J/cm2, 20 s, 60 mW, 8 points). The placebo application was similar to that of the experimental side but with laser simulation. The primary outcomes were pain control, swelling and trismus intensity at T1, T2, T3 and 7 days after surgery (T4). Data were analyzedbyANOVArepeated measures and Wilcoxon test (p<.05). The final sample consisted of 21 patients (42 teeth). There were no statistical differences for pain level between protocols A and B over time (p= .909), although the amount of analgesic medication was lower with protocol A at T2 (p=.022). There were no differences in swelling (p=.958) or trismus (p=.837) between the protocols used over time. Both protocols performed similarly for pain control, swelling and trismus. Therefore, for practical reasons, a single laser application in the immediate postoperative period could be indicated for the management of postoperative discomfort in lower third molar surgery.

O objetivo deste estudo foi testar dois protocolos de terapia com laser de baixa intensidade (LBI) para controle da dor, edema e trismo no período pós-operatório de cirurgias de terceiro molar inferior. Neste estudo randomizado, duplo-cego, controlado, de boca dividida foram incluídos pacientes que apresentavam os terceiros molares inferiores simetricamente. Um lado foi aleatoriamente designado para receber LBI aplicada imediatamente após a cirurgia (T1) e após 24 (T2) e 48 (T3) horas (Protocolo A). O lado oposto recebeu LBI imediatamente após a cirurgia e placebo após 24 e 48 horas (Protocolo B). A aplicação de LBI foi realizada intraoralmente (660nm, 5 J/cm2, 10 s, 20 mW, 4 pontos), seguida pela aplicação extraoral (789 nm, 30 J/cm2, 20 s, 60 mW, 8 pontos). O efeito do placebo foi similar ao experimental. Os desfechos primários eram dor, edema e intensidade do trismo nos tempos T1, T2, T3 e 7 após a cirurgia (T4). Os dados foram analisadosporANOVA e teste deWilcoxon (p<.05). A amostra final consistiu de 21 pacientes (43 dentes). Não houve diferença estatística para o nível de dor entre os protocolos A e B ao longo do tempo (p=.909), embora a quantidade de medicação analgésica tenha sido menor com o protocolo A em T2 (p= .022). Não houve diferença para edema (p=.958) ou trismo (p=.837) entre os protocolos ao longo do tempo. Em conclusão, a aplicação de LBI imediatamente após a cirurgia e após 24 e 48 horas (Protocolo A) apresenta melhor resultado para controle da dor. Ambos os protocolos foram similares para dor, edema e trismo. Portanto, por razões de praticidade, uma aplicação única de laser imediatamente após a cirurgia pode estar indicada para o manejo do desconforto pós-operatório em cirurgias de terceiros molares inferiores.

Implementation and Monitoring of the Family Planning Elevated Contraceptive Access Program, Utah, 2018‒2019.

Family Planning Elevated (FPE) is a contraceptive access initiative in Utah. FPE designed and utilized a comprehensive monitoring system to identify and respond to challenges implementing our initiative as they arose. Here, we describe the components of our monitoring system, and highlight how FPE's monitoring system successfully identified that Utah's Medicaid expansion was not widely adopted by eligible individuals. We then describe how FPE adapted to this challenge. (Am J Public Health. 2022;112(S5):S528-S531. https://doi.org/10.2105/AJPH.2022.306935).

Attitudes of dentists toward maintaining, repairing, or replacing direct composite resin restorations.

This study aimed to report the reasons for replacement of direct composite resin restorations in dental practices in Brazil. The study used a convenience sample of 213 dentists. A questionnaire was developed from previously validated instruments and sent electronically to prospective participants. The questions pertained to professional characteristics; criteria most frequently used in determining whether a direct composite resin restoration warranted replacement; and respondents' choice of treatment options (maintain, repair, or replace the restoration) in various clinical scenarios based on FDI World Dental Federation evaluation criteria, which are categorized into 3 groups: esthetic, functional, and biological properties. The descriptive statistical analysis was conducted using percentage frequencies, and associations between variables were tested using chi-square tests (α = 0.05). According to 47.9% of respondents, staining was the esthetic property that most often warranted replacement. For the functional property, 53.8% of respondents reported that fracture of material and retention was the most important factor indicating the need for replacement. For the clinical scenarios, 41.7% of respondents chose restoration replacement when evaluating esthetic properties, 59.8% when evaluating functional properties, and 64.4% when evaluating biological properties. Replacement, rather than maintenance or repair, was the most frequently reported clinical decision, and the dentists' professional profiles influenced treatment recommendations, with specialists exhibiting a slightly lower frequency of recommendations for replacement of direct composite resin restorations.

Is Zirconia Better Than Titanium Abutments for Soft Tissue Color? A Systematic Review and Meta-analysis of Spectrophotometric Evaluation.

PURPOSE: The aim of this systematic review was to evaluate the influence of zirconia and titanium as abutment materials on peri-implant soft tissue color. MATERIALS AND METHODS: The searched electronic databases included MEDLINE/PubMed, LILACS, Web of Science, Scopus, and LIVIVO. Two types of studies were included: randomized clinical trials (RCTs) and controlled clinical trials (CCTs) that compared zirconia (Zr) and titanium (Ti) abutments. The outcomes measured were as follows: implant crown esthetic index, visual analog scale, esthetic index, gingiva discoloration index-spectrophotometry, papilla index, recession index, and pink esthetic score. Two reviewers selected the records, assessed quality, and extracted data of included studies independently. RESULTS: A total of 323 patients enrolled in 13 studies were included in this analysis with 11 RCTs and 2 CCTs. Due to the wide variety of methodologies used, meta-analysis was only possible for RCTs that performed spectrophotometric analysis. The use of zirconia or titanium for implant abutments does not seem to be the principal factor for influencing peri-implant soft tissue color. The meta-analysis showed no difference between zirconia and titanium abutments. CONCLUSION: This study does not support any better advantage of the use of zirconia in comparison to the use of titanium related to peri-implant tissue color.

Travel to Mexico and uropathogen-antibiotic susceptibility mismatch in the emergency department.

INTRODUCTION: International travel results in an increased risk of colonization and infection with multidrug-resistant organisms. This study aimed to determine if recent travel to Mexico affects the rate of uropathogen-antibiotic susceptibility mismatch (UASM) in outpatients treated for urinary tract infection (UTI) in a South Texas emergency department (ED). METHODS: A retrospective cohort of adult patients presenting to the ED and treated outpatient for UTI from October 1, 2014, to February 25, 2020, was conducted at a community hospital located within approximately 15 miles of the United States-Mexico border. Rates of UASM were compared between patients with a history of recent travel to Mexico and those who have not recently traveled. RESULTS: A total of 192 patients were included, with 64 in the travel to Mexico group and 128 in the no travel group. UASM was significantly higher in the recent travel to Mexico group when compared to the no travel group (RR 1.49, 95% CI 1.03-2.13). Antibiotics most commonly associated with UASM included fluoroquinolones, cephalexin, and sulfamethoxazole-trimethoprim. There was no significant difference between the rates of resistance to first-line agents for the treatment of UTI among the two groups. CONCLUSION: In addition to known antibiotic resistance risk factors, recent travel to Mexico may increase the risk of UASM for ED patients with UTI. Considering the potential consequences of UTI treatment failure, antimicrobial stewardship services in the ED should include screening for antibiotic resistance risk factors and urine culture follow-up to ensure appropriate outpatient antibiotic therapy, especially among patients with recent international travel.

Facial profile changes due to bone cement graft to manage the hyperactive muscles of the gingival smile.

OBJECTIVE: To evaluate facial profile changes promoted by polymethyl methacrylate (PMMA) cement graft to reduce excessive gingival display due to hyperactivity of the elevator muscles of the upper lip during smiling. METHODS: Eleven patients (all females, age range: 20 to 43 years) presenting gingival smile that were treated with PMMA cement grafts in a private clinic were selected for this retrospective study. Three angular and ten linear cephalometric facial profile measurements were performed preoperatively (baseline, T1) and at least 6 months postoperatively (T2). Differences between T1 and T2 were verified by Wilcoxon test, and the correlation between the thickness of the graft and facial profile changes was statistically evaluated by Spearman's Coefficient test. The significance level was set at p< 0.05. RESULTS: The nasolabial angle (p= 0.03) and the labial component of the nasolabial angle showed statistically significant differences (p= 0.04), with higher values in T2. No correlations were found between the graft thickness and the statistically significant facial profile changes (p> 0.05). CONCLUSIONS: The PMMA bone cement graft projected the upper lip forward, thereby increasing the nasolabial angle without affecting the nasal component. No correlations between the graft thickness and the facial profile changes were detected.

[ECMO in Neonates with Congenital Diaphragmatic Hernia: The Experience of a Portuguese ECMO Referral Center]. / ECMO em Recém-nascidos com Hérnia Diafragmática Congénita: A Experiência de um Centro de Referência de ECMO em Portugal.

INTRODUCTION: The use of extracorporeal membrane oxygenation (ECMO) is considered by many authors as one of the most important technological advances in the care of newborns with congenital diaphragmatic hernia. The main objective of this study was to report the experience of a Portuguese ECMO center in the treatment of congenital diaphragmatic hernia. MATERIAL AND METHODS: Descriptive retrospective study of newborns with congenital diaphragmatic hernia requiring ECMO support in a Pediatric Intensive Care Unit from January 2012 to December 2019. Data collection using the Extracorporeal Life Support Organization registration and unit data base. RESULTS: Fourteen newborns were included, all with left congenital diaphragmatic hernia, in a total of 15 venoarterial ECMO cycles. The median gestational age was 38 weeks and the median birth weight was 2.950 kg. Surgical repair was performed before entry into ECMO in six, during in seven and after in one newborn. The average age at placement was 3.3 days and the median cycle duration was 16 days. Prior to ECMO, all newborns had severe hypoxemia and acidosis despite optimized ventilatory support, with nitric oxide and inotropic therapy. After 24 hours on ECMO, there was correction of acidosis, improvement of oxygenation and hemodynamic stability. All cycles presented mechanical complications, the most frequent being the presence of clots in the circuit. The most frequent physiological complications were hemorrhagic and embolic (three newborns suffered an ischemic stroke during the cycle). Five newborns (35.7%) died, all associated with complications (two strokes, two massive bleedings and one accidental decannulation). Chronic lung disease, poor weight gain and psychomotor developmental delay were the most frequent long-term morbidities. DISCUSSION: Despite technological advances in respiratory care and improved safety of the ECMO technique, the management of these newborns is complex and there are still several open questions, including the appropriate selection of patients, the best approach and time for surgical correction, and the treatment of pulmonary hypertension in the presence of persistent fetal shunts. CONCLUSION: Survival rate was higher than reported in 2017 Extracorporeal Life Support Organization report (64% versus 50%). Mechanical and hemorrhagic complications were very frequent.

Introdução: A utilização de oxigenação por membrana extracorporal (ECMO) é considerada por muitos autores como um dos maisimportantes avanços tecnológicos nos cuidados de recém-nascidos com hérnia diafragmática congénita. O principal objetivo deste estudo foi reportar a experiência de um centro de oxigenação por membrana extracorporal português no tratamento de hérnia diafragmática congénita.Material e Métodos: Estudo retrospetivo descritivo dos recém-nascidos com hérnia diafragmática congénita com necessidade de suporte de ECMO, numa unidade de Cuidados Intensivos Pediátricos de janeiro de 2012 a dezembro de 2019. Colheita de dados com recurso ao registo da Extracorporeal Life Support Organization e registo da unidade.Resultados: Incluídos 14 recém-nascidos, todos com hérnia diafragmática congénita esquerda, num total de 15 ciclos de ECMO veno-arterial. Mediana de idade gestacional de 38 semanas e de peso ao nascer de 2,950 kg. A correção cirúrgica foi realizada antes da entrada em ECMO em seis, durante em sete e após ciclo em um caso. A mediana de idade de colocação foi de 3,3 dias e a média de duração do ciclo foi de 16 dias. Previamente à ECMO, todos os recém-nascidos apresentavam hipoxemia e acidose grave apesar de suporte ventilatório otimizado, com terapêutica com oxido nítrico e inotrópicos. Após 24 horas em ECMO, verificou-se correção de acidose, melhoria de oxigenação e estado hemodinâmico. Todos os ciclos apresentaram complicações mecânicas, sendo a mais frequente a presença de coágulos no circuito. As complicações fisiológicas mais frequentes foram as hemorrágicas e embólicas (três recém-nascidos sofreram acidente vascular cerebral isquémico durante o ciclo). Cinco crianças (35,7%) morreram, estando todos os casos associados a complicações (duas com acidente vascular cerebral, duas com hemorragia maciça e uma descanulação acidental). A doença pulmonar crónica, má progressão ponderal e atraso do desenvolvimento psicomotor foram as morbilidades a longo prazo mais frequentes.Discussão: Apesar dos avanços tecnológicos nos cuidados respiratórios e melhoria da segurança da técnica ECMO, o manuseamento destes recém-nascidos é complexo e existem ainda várias questões em aberto, incluindo a selecção apropriada dos doentes, amelhor abordagem e tempo de correcção cirúrgica, e o tratamento da hipertensão pulmonar na presença de shunts fetais persistentes.Conclusão: A taxa de sobrevivência foi superior à reportada no relatório da Extracorporeal Life Support Organization de 2017 (64% vs 50%). As complicações mecânicas e hemorrágicas foram muito prevalentes.

Do denture teeth dimensions match natural anterior teeth? / As dimensões dos dentes artificiais correspondem aos dentes anteriores naturais?

ABSTRACT Objective To compare dimensions of natural maxillary anterior teeth and several denture teeth molds and also address differences between genders. Methods A single examiner with a digital caliper measured dental casts of 41 males and 55 females in order to determine CIW (central incisor width), CIL (central incisor length) and WS (width of anterior teeth on a straight line). In addition, WC (width of anterior teeth on a curve) was measured with a flexible ruler. These parameters were also observed on three denture teeth mold charts: Premium Pala, Vivodent and Trilux. The comparison between genders was analyzed using Student's t-test (?=.05), while absolute frequencies within several ranges were used to compare natural and denture teeth. Results CIW, CIL, WS and WC obtained from males were significantly higher than those found for females (p<0.05). CIW of nearly half of natural and denture teeth were within 8.0-8.5 mm. Almost half of natural teeth presented CIL values within 10.6-11 mm, while the highest frequency of denture teeth was observed within 9.6-10 mm. The majority of natural and denture teeth presented WS values within 42 to 49 mm. Only one denture teeth chart described WC values, which were mainly observed within 44-51 mm, while the majority of WC values obtained from natural teeth ranged from 48 to 55 mm. Conclusion Some commercially available denture teeth present dimensions not observed in natural teeth. Teeth dimensions in function of gender differences must be considered when selecting denture teeth.

RESUMO Objetivo Comparar as dimensões dos dentes anteriores superiores naturais e de diversos dentes artificiais para próteses e também abordar as diferenças entre os gêneros. Métodos Um único examinador mediu com um paquímetro digital dentes naturais de 41 homens e 55 mulheres para determinar CIW (largura do incisivo central), CIL (comprimento do incisivo central) e WS (largura dos dentes anteriores superiores em linha reta). Adicionalmente, CC (largura dos dentes anteriores em uma curva) foi aferida com uma régua flexível. Esses parâmetros também foram observados em três cartas moldes de dentes artificiais para prótese: Premium Pala, Vivodent e Trilux. A comparação entre os sexos foi analisada pelo teste t de Student (?=0,05), enquanto frequências absolutas foram usadas para comparar medidas dos dentes naturais e artificiais. Resultados CIW, CIL, WS e WC obtidos de homens foram significativamente maiores do que aqueles encontrados para mulheres (p<0,05). CIW de quase metade de dentes naturais e artificiais estavam entre 8,0-8,5 mm. Quase metade dos dentes naturais apresentaram valores CIL entre 10,6-11 mm, enquanto a maior frequência de dentes artificiais foi observada entre 9,6-10 mm. A maioria dos dentes naturais e artificiais apresentaram valores WS entre 42-49 mm. Apenas uma carta molde de dentes artificiais descreveu os valores de WC, que foram observados principalmente entre 44-51 mm, enquanto a maioria dos valores de WC obtidos em dentes naturais variaram de 48 a 55 mm. Conclusão Alguns dentes artificiais para próteses disponíveis comercialmente apresentam dimensões não observadas nos dentes naturais. As dimensões dos dentes em função das diferenças de gênero devem ser consideradas na seleção dos dentes artificiais.

Influence of different application protocols of universal adhesive system on the clinical behavior of Class I and II restorations of composite resin - a randomized and double-blind controlled clinical trial.

BACKGROUND: Multimode adhesives incorporate the versatility of adapting to various clinical situations by its capacity to be used in different protocols. This study aimed to evaluate the clinical behavior of composite resin direct restorations (Class I and II) performed with different universal dentin adhesive application protocols comparing adapted FDI and adapted USPHS criteria. METHODS: The current study is a randomized, double-blind, split-mouth, and convenience sample controlled clinical trial. The participants (age ≥ 18 years) had restorative need of Class I and/or II due to the presence of carious lesions and/or unsatisfactory restorations in at least three dental elements. Each participant received three application protocols for Scotchbond Universal adhesive (3M ESPE), one in each tooth to be restored: ER = etch-and-rinse + adhesive (n = 50); SEE = selective enamel etch + adhesive (n = 50) and SE = self-etch adhesive (n = 50). All teeth were restored in a similar way using Filtek™ Supreme composite resin (3M ESPE). Restorations were evaluated using the adapted FDI and adapted USPHS criteria, at baseline after 7 to 21 (12.02 ± 5.68) days (T1; n = 50 per group) and after 12 to 20 (15.8 ± 2.7) months (T2; n = 46 per group) by two previously calibrated evaluators (Kappa > 0.80). The statistical tests were performed between groups (Friedman), intragroup (Wilcoxon), and between the criteria considering acceptable and not acceptable restorations (McNemar), α = 0.05. RESULTS: A statistically significant difference was observed only for the property "superficial staining", between groups at T2 (p = 0.01) for ER (n = 13 with score 2 or more) and SEE (n = 3 with score 2 or more) and intragroup for ER (T1, n = 1 with score 2 or more; T2, n = 13 with score 2 or more, p = 0.001) and SE (T1, n = 0 with score 2 or more; T2, n = 8 with score 2 or more p = 0.007). For the other comparisons between groups, intragroup, and between the adapted FDI and adapted USPHS criteria, there were no statistically significant differences (p ≥ 0.05). CONCLUSIONS: It can be concluded that the different application protocols of the universal adhesive resulted in clinically "acceptable" restorations after 15.8 ± 2.7 months of follow-up. Adapted FDI and adapted USPHS criteria provided similar results to each other. TRIAL REGISTRATION: Number in Brazilian Registry of Clinical Trials (ReBEC): RBR-9p3hdp. Registered 24 May 2015.

Comparison of Dimensions of the Nasopharynx and Oropharynx Using Different Anatomical References: Is There Equivalence?

PURPOSE: To evaluate the equivalence of the volumes obtained using different anatomic references to measure the nasopharynx and oropharynx on cone-beam computed tomography (CBCT) scans. We hypothesized that no variations would be found in the nasopharynx and oropharynx dimensions when measured using different measurement methods. MATERIALS AND METHODS: A total of 40 CBCT scans of patients with skeletal Class I (age range, 20 to 50 years) were measured independently by 2 of us. The nasopharynx and oropharynx subregions were volumetrically measured using the adopted limits of 5 different measurement methods (3 for the nasopharynx and 2 for the oropharynx) and InVivoDental software, version 5.4 (Anatomage, San Jose, CA). The minimum area and the minimum area of localization were also evaluated. The intra- and interexaminer concordance for the measurements from the different methods were verified using the interclass correlation coefficient (ICC). The analysis of variance for repeated measures was used to compare the measurements from the 3 nasopharynx methods. The paired t test was used to compare the measurements from the 2 oropharynx methods. The statistical tests were performed at the 5% significance level using SPSS software, version 22.0 (IBM Corp, Armonk, NY). RESULTS: The intra- and interexaminer ICC values were greater than 0.8. We found a statistically significant difference in the volume measurements among the 3 nasopharynx methods (P = .001). However, no differences were found in the minimum area or minimum area of localization comparisons. Statistically significant differences were also observed for the volume, minimum area, and minimum area of localization between the 2 oropharynx methods (P = .001). CONCLUSIONS: Studies that have used different methods of measurement should not be directly compared. The different measurement methods used for nasopharynx and oropharynx evaluations should not be compared.
