RESUMO

Soluble molecules of programmed death ligand 1 (sPD-L1) are known to modulate T-cell depletion, an important mechanism of hepatitis B virus (HBV) persistence and liver disease progression. In addition, PD-L1 polymorphisms in the 3'-UTR can influence PD-L1 expression and have been associated with cancer risk, although not definitively. The purpose of this study was to investigate the association of PD-L1 polymorphisms and circulating levels of sPD-L1 in HBV infection and live disease progression. In this study, five hundred fifty-one HBV infected patients of the three clinically well-defined subgroups chronic hepatitis B (CHB, n = 186), liver cirrhosis (LC, n = 142) and hepatocellular carcinoma (HCC, n = 223) and 240 healthy individuals (HC) were enrolled. PD-L1 polymorphisms (rs2297136 and rs4143815) were genotyped by in-house validated ARMS assays. Logistic regression models were applied in order to determine the association of PD-L1 polymorphisms with HBV infection as well as with progression of related liver diseases. Plasma sPD-L1 levels were quantified by ELISA assays. The PD-L1 rs2297136 AA genotype was associated with HBV infection susceptibility (HBV vs. HC: OR = 1.6; 95%CI = 1.1-2.3; p = 0.0087) and disease progression (LC vs. CHB: OR = 1.8; 95%CI = 1.1-2.9; p = 0.018). Whereas, the rs2297136 GG genotype was a protective factor for HCC development. Plasma sPD-L1 levels were significantly high in HBV patients (p < 0.0001) and higher in the LC followed by CHB and HCC groups. High sPD-L1 levels correlated with increased liver enzymes and with advanced liver disease progression (Child-pugh C > B > A, p < 0.0001) and BCLC classification (BCLC D > C > B > A, p = 0.031). We could, for the first time, conclude that PD-L1 rs2297136 polymorphism and plasma sPD-L1 protein levels associate with HBV infection and HBV-related liver disease progression.

RESUMO

Resumen La trombosis venosa cerebral (TVC) es una presentación clínica poco común del tromboembolismo venoso caracterizada por cefalea, crisis convulsivas, déficits neurológicos focales y papiledema. El diagnóstico es confirmado con Tomografía axial computarizada (TAC) de cráneo y Resonancia magnética nuclear (RMN) cerebral. La TVC tiene una relación importante con el virus de inmunodeficiencia humana (VIH), ya que los pacientes VIH positivos cursan con hiperviscosidad san guínea, alteraciones de factores anticoagulantes endógenos y riesgo de sobreinfección, entre otros; que predisponen a estados protrombóticos y lesión vascular como lo es la TVC. El tratamiento de la TVC es terapia anticoagulante, por lo general se utiliza heparina no fraccionada o heparina de bajo peso molecular para la fase aguda y anticoagulantes orales como la warfarina para el mantenimiento posterior. Reportamos el primer caso documentado de TVC en un paciente VIH positivo en Colombia.


Abstract Cerebral venous thrombosis (CVT) is a rare clinical presentation of venous thromboembolism characterized by headache, seizures, neurological deficits and papi lledema. The diagnosis is confirmed using computed tomography scan (CT scan) and magnetic resonance imaging (MRI) of the brain. CVT has an important relationship with the human immunodeficiency virus (HIV) given that HIV-positive patients may present with blood hyperviscosity, irregular levels of endogenous anticoagulation factors and risk of sepsis among others, that predispose to prothrombotic states and vascular injury such as CVT. The treatment of CVT is anticoagulant therapy, generally unfractionated heparin or low molecular weight heparin for the early phase and oral anticoagulants such as warfarin for the late phase. This case reports the first documented case of CVT in an HIV positive patient in Colombia.

Materiales y Métodos: Se realizó una cohorte retrospectiva, entre enero del 2014 y enero del 2018. Se utilizó una ficha de recolección de datos. Se obtuvieron los riesgos relativos (RR) crudos y ajustados, con intervalos de confianza al 95%. Resultados: Participaron 83 pacientes. El 41,2% de las mujeres presentaron infección en la cavidad postquistectomía y la mediana de edad de los pacientes infecta dos fue de 33 años. Los antecedentes patológicos que se relacionaron con la infección fueron obesidad o sobrepeso (62,5%), neoplasia previa (100%) y enferme dad inmunológica previa (31%). La infección en cavidad residual postquistectomía estuvo relacionada a la presencia de obesidad o sobrepeso, diabetes mellitus, neoplasia previa , cirugía previa y al uso de antibióticos posteriores a la cirugía. Conclusiones: La obesidad o sobrepeso, diabetes mellitus, haber padecido alguna neoplasia o cirugía previa y el uso de antibióticos luego de la cirugía; son factores de riesgo para la infección en cavidad residual postquistectomía hepática en los pacientes del Hospital Nacional Ramiro Prialé Prialé EsSalud de Huancayo, Perú.


Abstract Objective: To determine the risk factors with the infection in the residual cavity after hepatic cystectomy in the patients of the Ramiro Prialé Prialé hospital - EsSalud -Huancayo. Materials and Methods: A retrospective cohort was conducted, between January 2014 and January 2018. A data collection sheet was used. Crude and adjusted relative risks (RR) were obtained, with 95% confidence intervals. Results: 83 patients participated. 41.2% of women infected in the post-cystectomy cavity and the median age of infected patients was 33 years. The pathological antecedents that were related to the infection were obesity or overweight (62.5%), previous neoplasia (100%) and previous immune disease (31%). Post-cystectomy residual cavity infection was affected by the presence of obesity or overweight (aRR: 1.56; 95% CI: 1.15-2.13; p value = 0.005), diabetes mellitus (aRR: 2.67; 95% CI : 2.09-3.41; p value <0.001), previous neoplasia (aRR: 2.49; 95% CI: 1.94-3.20; p value <0.001), previous surgery (aRR: 1.49; 95% CI: 1.36-1.64; p value <0.001) and the use of post-surgery antibiotics (aRR: 2.14; 95% CI: 1.30-3.51; p value = 0.003) Conclusions: Obesity or overweight, diabetes mellitus, having suffered some neoplasia or previous surgery and the use of antibiotics after surgery; they are factors associated with infection in the residual post-cystectomy liver cavity in patients of the Ramiro Prialé Prialé EsSalud National Hospital in Huancayo, Peru.

RESUMO

Os ferimentos por arma de fogo (FAF) são um grande problema de saúde pública. Na face, a mandíbula é o local de maior incidência, sendo a região de corpo mandibular a mais atingida e as lesões aos tecidos moles frequentemente a ela associadas. Em alguns casos, tais ferimentos apresentam-se de difícil resolução, sobretudo, em casos de fraturas cominutivas e lesões de tecidos moles com alta complexidade. Isso torna o atendimento desses pacientes um desafio para cirurgiões buco-maxilo-faciais. Desta forma, o objetivo deste artigo é relatar um caso de FAF em terço inferior da face, com comprometimento de tecidos moles e mandíbula, pela equipe de Cirurgia e Traumatologia Bucomaxilofacial do Hospital Geral do Estado - Bahia. Paciente de 28 anos de idade, sexo feminino, vítima de FAF em terço inferior da face, por disparo acidental de espingarda. Ao exame clínico, pode-se observar ferimento perfuro-contuso em região de mandíbula e fratura cominutiva de corpo e ângulo mandibular à direita. A paciente foi submetida à cirurgia para remoção de fragmentos ósseos/corpos estranhos, fixação dos cotos com placa de reconstrução 2.4mm e sutura dos planos, em mesmo tempo cirúrgico, reestabelecendo a função da mandíbula. Portanto, devido à fisiopatologia variável dos FAF na mandíbula, não se indica um único padrão de tratamento para as fraturas cominutivas. Além disso, é indispensável o emprego de protocolos de limpeza cirúrgica imediata e antibioticoterapia nos casos com alto grau de cominuição, bem como, sugere-se realizar o tratamento definitivo o mais breve possível(AU)


Firearm injuries (FIs) are a major public health problem. On the face, the mandible is the place with the highest incidence of this trauma, with the mandibular body region being the most affected and the lesions to the soft tissues frequently associated with it. In some cases, such injuries are difficult to resolve, especially in cases of comminuted fractures and soft tissue injuries with high complexity. This makes the care of these patients a challenge for oral and maxillofacial surgeons. Thus, the objective of this article is to report a case of care for a FAF victim in the lower third of the face, with soft tissue and mandible involvement, by the Maxillofacial Surgery and Traumatology team at the Hospital Geral do Estado - Bahia. 28-year-old female patient, victim of FAF in the lower third of the face, due to acidental shotgun firing. On clinical examination, a perforated-blunt wound can be seen in the mandible region and comminuted fracture of the body and angle of the mandible on the right. The patient underwent surgery to remove bone fragments / foreign bodies, fix the stumps with a 2.4 mm reconstruction plate and suture the planes, at the same surgical time, reestablishing the function of the mandible. Therefore, due to the variable pathophysiology of FAF in the mandible, a single treatment pattern is not indicated for comminuted fractures. In addition, it is essential to use immediate surgical cleaning protocols and antibiotic therapy in cases with a high degree of comminution, as well as, it is suggested to carry out the definitive treatment as soon as possible(AU)

RESUMO

Resumen Objetivo: Describir la supervivencia a siete años y los principales factores asociados a esta, en las personas con VIH que fueron atendidas en el sistema de salud colombiano entre 2011 a 2018. Métodos: Análisis de supervivencia de una cohorte de 64 039 personas diagnosticadas con VIH en Colombia. Se aplicó el método de Kaplan-Meier para estimar la probabilidad de supervivencia a partir de la fecha del diagnóstico. Se ajustó un modelo de supervivencia paramétrico flexible de Royston Parmar. Resultados: La estimación de la supervivencia global a 7 años fue de 94,8% (IC 95%: 94,5-95,2). El mayor riesgo de muerte se presentó en los hombres (HR: 1,2; IC 95%: 1,1-1,4; p: 0,010); en personas ≥50 años de edad (HR: 3,1; IC 95%: 1,6-6,3; p: 0,002); en el régimen subsidiado (HR: 2,2; IC 95%: 1,9-2,5; p: <0,001); en la etapa sida (HR: 2,8; IC 95%: 2,1-3,7; p: <0,001); en quienes presentaron la última carga viral detectable (HR: 7,1; IC 95%: 6,0-8,3; p: <0,001); y en quienes mostraron conteo de linfocitos T CD4+ <350 células/μL (HR: 1,9; IC 95%: 1,4-2,4; p: <0,001). Conclusión: La probabilidad de la supervivencia de las personas que viven con VIH aumenta al ser diagnosticados en edades jóvenes, en quienes presenten un recuento de linfocitos T CD4+ ≥350 células/μL, una carga viral indetectable (< 50 copias/mL) y no se encuentren en etapa sida.


Summary Objective: to describe the seven-year survival and predictors of mortality among people with HIV who were treated in the Colombian health system between 2011 and 2018. Methods: 64 039 people diagnosed with HIV in Colombia were included. Kaplan-Meier analysis estimated the probability of survival from the date of diagnosis. A Royston Parmar flexible parametric survival model was fitted. Results: The overall survival at 7 years was 94.8% (95% CI: 94.5-95.2). Survival was related to sex (men, HR: 1.2; 95% CI: 1.1-1.4; p: 0.010); people ≥50 years of age (HR: 3.1; 95% CI: 1.6-6.3; p: 0.002); subsidized regime (HR: 2.2; 95% CI: 1.9-2.5; p: <0.001); AIDS stage (HR: 2.8; 95% CI: 2.1-3.7; p: <0.001); a detectable viral load (HR: 7.1; 95% CI: 6.0-8.3; p: <0.001); and a CD4+ Lymphocyte count <350 cells/μL (HR: 1.9; 95% CI: 1.4-2.4; p: <0.001). Conclusion: The probability of survival of people living with HIV increases when they are diagnosed at a young age, in those with a CD4+ T Lymphocyte count ≥350 cells/μL, an undetectable viral load (<50 copies/mL) and are not in the AIDS stage.

RESUMO

Resumen Objetivo: Comparar la expresión de mRNA y proteínas de SFRP1, PTPRN, CDO1, EDNRB, CDX2, EPB41L3 y HAND1 en pacientes con lesión intra-epitelial cervical de bajo y alto grado, con posterior progresión o regresión. Material y Método: Se realizó análisis de expresión de genes mediante RT-PCR y análisis de expresión de proteínas por inmunohistoquímica. El análisis estadís tico fue realizado con las pruebas: Wilcoxon, coeficiente de correlación de Spearman e índice de concordancia. Las muestras fueron pareadas en momento 1 y momento 2. Resultados: SFRP1 mostró tendencia de mayor expresión de mRNA en lesión intra-epitelial de bajo grado (momento 2) Vs. alto grado (momento 1). La expresión de proteínas por inmunohistoquímica de SFRP1 en casos de progresión (83,3 %) mostró disminución en su graduación (p = 0,0313*); los demás genes en estudio no tuvieron cambios estadísticamente significativos. Discusión: SFRP1 mostró comportamiento ajustado a resultados de estudios previos donde se encontró hipermetilado en lesiones intra-epiteliales de alto grado; su subexpresión por hipermetilación se reportó en otros canceres, proceso que colabora con su silenciamiento y transición epitelial-mesenquimatosa del cáncer de cuello uterino. Conclusiones. SFRP1 es potencial biomarcador en lesiones preneoplásicas del cuello uterino asociadas al virus de papiloma humano.


Abstract Objective. The aim of this work was to compare the expression of mRNA and proteins of SFRP1, PTPRN, CDO1, EDNRB, CDX2, EPB41L3 and HAND1 in patients with low and high grade cervical intraepithelial lesion, with subsequent progression or regression. Material and Methods: Gene expression analysis was conducted through RT-PCR and protein expression analysis was performed by immunohistochemistry. The statistics analysis were Wilcoxon test, Spearman's correlation coefficient and concordance index. The samples were paired during moment 1 (initial patient diag nosis) and moment 2 (follow-up histological diagnosis). Results: SFRP1 showed a trend of higher mRNA expression in low-grade intra-epithelial lesions (moment 2) Vs. high-grade (moment 1). The expression of proteins by immunohistochemistry of SFRP1 in progression cases (83.3%) showed a decrease in its graduation (p = 0.0313*); the other genes under study had no statistically significant. Discussion: SFRP1 showed a biological behavior adjusted to the results of previous studies where hypermethylation was found in high-grade intra-epithelial lesions; its subexpression by hypermethylation has been reported in other cancers, a process that collaborates with its silencing and epithelial-mesenchymal tran sition of cervical. Conclusions. SFRP1 is a potential biomarker in preneoplastic lesions of the cervix associated with human papillomavirus.

RESUMO

Resumen Objetivo: Describir la proporción, características clínicas, demográficas y programáticas de casos fatales de coinfección TB/VIH de Cali-Colombia, en 2017. Material y Método: Estudio de corte transversal, con información de las bases de datos del programa de tuberculosis, las historias clínicas y unidades de análisis de mortalidad disponibles. Resultados: Se depuraron 257 casos fatales por TB, el 24,5% (63/257) falleció con coinfección TB/VIH. La mediana de edad fue 43 años (Rango Intercuartílico: 30-52), 73% (46/63) eran hombres, 76,2% (48/63) no pertenecían al régimen contributivo, 28,6% eran habitantes de calle. 81,2% (39/48) eran casos nuevos de TB, 76,6% (37/47), inició tratamiento; al 74,6% (47/63) se les realizó unidad de análisis de mortalidad. La presentación pulmonar fue frecuente (75,9%-44/58), en 60% de los registros se observó desnutrición (Índice de Masa Corporal <20), en 39,7% (25/63) dependencia al alcohol, tabaco o farmacodependencia. Conclusiones: La mortalidad asociada a TB/VIH es prevenible, pero en 2017 representó la cuarta parte de la mortalidad por TB en Cali. Hombres adultos con condiciones de vulnerabilidad social, diagnosticados en estados avanzados de enfermedad, fueron blanco de fatalidad. Mejorar los sistemas de información e integrar los programas de TB/VIH, deben ser estrategias prioritarias para la salud pública en Colombia.


Abstract Objective: To describe the proportion, clinical, demographic and programmatic characteristics of fatal cases of TB/HIV coinfection from Cali-Colombia, in 2017. Material and Method: Cross-sectional study, with information from the TB program databases, clinical records and mortality analysis units available. Results: 257 TB fatal cases were cleared in Cali in 2017, 24.5% (63/257) of these died with TB/HIV coinfection. The median age was 43 years (Interquartile Range: 30-52), 73% (46/63) were men, 76.2% (48/63) did not belong to the contributory health regimen, 28.6% were homeless. 81.2% (39/48) were new TB cases, 76.6% (37/47) started treatment; 74.6% (47/63) had mortality analysis register. Pulmonary presentation was frequent (75.9% -44 / 58), in 60% of the registries malnutrition was observed (Body Mass Index <20), in 39.7% (25/63), dependence on alcohol, tobacco or drug dependence was registered. Conclusions: Mortality associated with TB/HIV is preventable, but in 2017 it represented a quarter of the TB mortality in Cali. Adult men with conditions of social vulnerability, diagnosed in advanced stages of disease, were fatally targeted. Improving information systems and integrating TB/HIV programs should be priority strategies for public health in Colombia.

Método: estudo qualitativo realizado em ambiente online, com a participação de 34 profissionais de saúde. Foram realizadas entrevistas semiestruturadas, interpretadas segundo análise temática. Resultados: duas categorias analíticas emergiram dos dados, indicando que os significados atribuídos à morte pelos participantes foram: como um processo inerente ao ciclo da vida humana, passagem para a outra vida, e fim do sofrimento tanto do paciente quanto dos profissionais de saúde. As dificuldades que apontaram em lidar com a morte se referem à falta de suporte psicológico, escassez de conhecimento sobre morte, cuidados paliativos e comunicação de más notícias. Conclusão: os profissionais construíram diferentes significados à morte de seus pacientes, tais como um processo natural da vida, vontade de um ser superior, passagem para uma nova existência e término do sofrimento dessas pessoas.


Objective: to understand the construction of meanings of death by healthcare professionals caring for people with cancer. Method: this qualitative study was carried out in an online environment through semi-structured interviews of 34 health professionals, which were interpreted using thematic analysis. Results: two analytical categories emerged from the data, indicating that the meanings attributed to death by the participants were: a process inherent in the human life cycle, a transition to the next life, and an end to the suffering of both patient and health professionals. The difficulties they pointed to in dealing with death related to lack of psychological support, lack of knowledge about death, palliative care, and communicating bad news. Conclusion: the professionals constructed different meanings to their patients' deaths: a natural process of life, the will of a higher being, a transition to a new existence, and an end to these people's suffering.

RESUMO

Objetivo: descrever a incidência de complicações em feridas operatórias de mastectomia e identificar fatores associados. Método: estudo retrospectivo desenvolvido em uma coorte hospitalar de 545 mulheres mastectomizadas por câncer de mama no ano 2018 em um centro de assistência de alta complexidade em oncologia da cidade do Rio de Janeiro, Brasil, após aprovação por Comitê de Ética em Pesquisa. Os dados foram coletados a partir dos prontuários, permitindo cálculos da taxa de incidência e da razão da taxa de incidência para cada complicação. Resultados: a complicação que apresentou maior taxa de incidência foi o sangramento (57,14/100 mastectomias-dia), tendo como fatores associados a raça/cor da pele não branca (Razão da Taxa de Incidência: 3,11) e a diabetes mellitus (Razão da Taxa de Incidência: 0,48). Conclusão: os fatores associados ao sangramento da ferida operatória apontam para a necessidade de novas práticas no cuidado ao pós-operatório de mulheres mastectomizadas.


Objective: to describe the incidence of complications in mastectomy surgical wounds and to identify associated factors. Method: this retrospective study was conducted in a hospital cohort of 545 women mastectomized for breast cancer in 2018 at a high-complexity cancer care center Rio de Janeiro City, Brazil, after approval by the research ethics committee. Data were collected from medical records, allowing incidence rate and incidence rate ratio to be calculated for each complication. Results: the complication with the highest incidence rate was bleeding (57.14/100 mastectomies-day), associated factors being non-white race/skin color (incidence rate ratio 3.11) and diabetes mellitus (incidence rate ratio 0.48). Conclusion: the factors associated with bleeding from the surgical wound point to the need for new practices in post-operative care for women with mastectomies.

RESUMO

Diversion colitis (DC) that was refractory to standard treatments was successfully treated with infliximab. A 24-year-old man with a transverse colostomy suffered from severe DC. Topical steroids, 5-aminosalicylic acid (5-ASA) enemas and synbiotics were initially effective, and the colostomy was successfully closed with a covering ileostomy to minimise the risk of anastomotic leakage owing to the damaged colon. DC subsequently relapsed in the entire colon and was refractory to the previous protocol and autologous faecal transplantation. Intravenous methylprednisolone and oral 5-ASA were discontinued owing to possible adverse effects. Infliximab with intravenous prednisolone was introduced, and the protocol was so effective in suppressing the acute colitis that total colectomy was avoided. The stoma was subsequently closed, and the patient is currently symptom-free. Infliximab is used for ulcerative colitis but could also be effective against severe DC.

RESUMO

We report a case involving intravenous sedation for third molar extractions in a 32-year-old man with citrullinemia type I (CTLN1), a genetic disorder that affects the urea cycle. The patient was diagnosed with CTLN1 after he exhibited seizures soon after birth and was intellectually disabled because of persistent hyperammonemia, although his recent serum ammonia levels were fairly well controlled. We planned to minimize his preoperative fasting, continue his routine oral medications, and monitor his serum ammonia levels at least twice. Sedation with midazolam and a propofol infusion was planned to suppress his gag reflex and reduce protein hypercatabolism due to stress. Epinephrine-containing local anesthetics, which enhance protein catabolism, were avoided, replaced by plain lidocaine for blocks and prilocaine with felypressin for infiltration anesthesia. No significant elevation in ammonia levels was observed. In patients with CTLN1, sedation can be useful for preventing hyperammonemia. Patients who develop symptomatic hyperammonemia may require urgent/emergent treatment involving other medical specialists. Therefore, preoperative endocrinology consultation, perioperative monitoring of serum ammonia levels, and preemptively coordinating for appropriate care in the event hyperammonemia occurs should all be considered.

RESUMO

Importance: Eosinophilic esophagitis (EoE) is a chronic immune-mediated inflammatory disease of the esophagus that affects an estimated 34.4/100 000 people in Europe and North America. EoE affects both children and adults, and causes dysphagia, food impaction of the esophagus, and esophageal strictures. Observations: EoE is defined by symptoms of esophageal dysfunction, such as vomiting, dysphagia, or feeding difficulties, in a patient with an esophageal biopsy demonstrating at least 15 eosinophils per high-power field in the absence of other conditions associated with esophageal eosinophilia such as gastroesophageal reflux disease or achalasia. Genetic factors and environmental factors, such as exposure to antibiotics early in life, are associated with EoE. Current therapies include proton pump inhibitors; topical steroid preparations, such as fluticasone and budesonide; dietary therapy with amino acid formula or empirical food elimination; and endoscopic dilation. In a systematic review of observational studies that included 1051 patients with EoE, proton pump inhibitor therapy was associated with a histologic response, defined as less than 15 eosinophils per high-power field on endoscopic biopsy, in 41.7% of patients, while placebo was associated with a 13.3% response rate. In a systematic review of 8 randomized trials of 437 patients with EoE, topical corticosteroid treatment was associated with histologic remission in 64.9% of patients compared with 13.3% for placebo. Patients with esophageal narrowing may require dilation. Objective assessment of therapeutic response typically requires endoscopy with biopsy. Conclusions and Relevance: EoE has a prevalence of approximately 34.4/100 000 worldwide. Treatments consist of proton pump inhibitors, topical steroids, elemental diet, and empirical food elimination, with esophageal dilation reserved for patients with symptomatic esophageal narrowing.

RESUMO

Importance: After decades of decline, the US cardiovascular disease mortality rate flattened after 2010, and racial and ethnic differences in cardiovascular disease mortality persisted. Objective: To examine 20-year trends in cardiovascular risk factors in the US population by race and ethnicity and by socioeconomic status. Design, Setting, and Participants: A total of 50 571 participants aged 20 years or older from the 1999-2018 National Health and Nutrition Examination Surveys, a series of cross-sectional surveys in nationally representative samples of the US population, were included. Exposures: Calendar year, race and ethnicity, education, and family income. Main Outcomes and Measures: Age- and sex-adjusted means or proportions of cardiovascular risk factors and estimated 10-year risk of atherosclerotic cardiovascular disease were calculated for each of 10 two-year cycles. Results: The mean age of participants ranged from 49.0 to 51.8 years and the proportion of women from 48.2% to 51.3% in the surveys. From 1999-2000 to 2017-2018, age- and sex-adjusted mean body mass index increased from 28.0 (95% CI, 27.5-28.5) to 29.8 (95% CI, 29.2-30.4); mean hemoglobin A1c increased from 5.4% (95% CI, 5.3%-5.5%) to 5.7% (95% CI, 5.6%-5.7%) (both P < .001 for linear trends). Mean serum total cholesterol decreased from 203.3 mg/dL (95% CI, 200.9-205.8 mg/dL) to 188.5 mg/dL (95% CI, 185.2-191.9 mg/dL); prevalence of smoking decreased from 24.8% (95% CI, 21.8%-27.7%) to 18.1% (95% CI, 15.4%-20.8%) (both P < .001 for linear trends). Mean systolic blood pressure decreased from 123.5 mm Hg (95% CI, 122.2-124.8 mm Hg) in 1999-2000 to 120.5 mm Hg (95% CI, 119.6-121.3 mm Hg) in 2009-2010, then increased to 122.8 mm Hg (95% CI, 121.7-123.8 mm Hg) in 2017-2018 (P < .001 for nonlinear trend). Age- and sex-adjusted 10-year atherosclerotic cardiovascular disease risk decreased from 7.6% (95% CI, 6.9%-8.2%) in 1999-2000 to 6.5% (95% CI, 6.1%-6.8%) in 2011-2012, then did not significantly change. Age- and sex-adjusted body mass index, systolic blood pressure, and hemoglobin A1c were consistently higher, while total cholesterol was lower in non-Hispanic Black participants compared with non-Hispanic White participants (all P < .001 for group differences). Individuals with college or higher education or high family income had consistently lower levels of cardiovascular risk factors. The mean age- and sex-adjusted 10-year risk of atherosclerotic cardiovascular disease was significantly higher in non-Hispanic Black participants compared with non-Hispanic White participants (difference, 1.4% [95% CI, 1.0%-1.7%] in 1999-2008 and 2.0% [95% CI, 1.7%-2.4%] in 2009-2018]). This difference was attenuated (-0.3% [95% CI, -0.6% to 0.1%] in 1999-2008 and 0.7% [95% CI, 0.3%-1.0%] in 2009-2018) after further adjusting for education, income, home ownership, employment, health insurance, and access to health care. Conclusions and Relevance: In this serial cross-sectional survey study that estimated US trends in cardiovascular risk factors from 1999 through 2018, differences in cardiovascular risk factors persisted between Black and White participants; the difference may have been moderated by social determinants of health.

RESUMO

A 23-year-old female-treated patient of osteomalacia and secondary hyperparathyroidism with hypophosphatemia presented with a 5-year history of bilateral groin pain and stiffness of both hips and difficulty in walking. Plain radiographs of the pelvis showed bilateral coxa vara deformity. She was managed surgically by a single-stage bilateral subtrochanteric corrective osteotomy with the internal fixation. After the osteotomy healing at 3 months, the patient was pain free and walked comfortably with an increased range of hip motion.

RESUMO

ABSTRACT: Transforaminal endoscopic lumbar discectomy (TELD) is useful for soft lumbar disc herniation (LDH). Although the transforaminal approach can reach the foraminal disc zone, the risk of exiting nerve root irritation along the path is considerable. Few studies have assessed the difficulties of TELD for foraminal LDH. The objective of this study is to compare the clinical results of TELD between foraminal or far-lateral LDH and paramedian LDH.Between June 2016 and July 2017, 135 consecutive patients with single-level LDH were treated with TELD for 2 years. Among them, 25 patients had foraminal or far-lateral LDH (foraminal group), and the remaining 110 patients had central or subarticular LDH (paramedian group). Perioperative data and clinical outcomes were evaluated using the visual analog pain scale, Oswestry Disability Index, and modified Macnab criteria.The foraminal group showed a higher rate of significant access pain (24.00% vs 8.19%, P < .05). The foraminal group also had a longer duration of surgery, length of hospital stay, and return to work (all P < .05). Pain scores and functional status were significantly improved in both groups. Although there were no differences in the outcomes at 2 years postoperatively, early pain and disability at 6 weeks were higher in the foraminal group.Ironically, the early clinical results of TELD for foraminal LDH may be less favorable than those for paramedian LDH. Therefore, great care should be taken during TELD for foraminal or far-lateral LDH.

RESUMO

ABSTRACT: No studies have examined the issue of intraabdominal port-site adhesion following single-port access (SPA) laparoscopic surgeries. The purpose of the present study was to investigate the clinical effects of temperature-sensitive adhesion barrier solution in preventing periumbilical adhesion in SPA laparoscopy. This was a prospective, single-arm study in which patients were given GUARDIX-SGTM after SPA laparoscopic surgery for benign gynecologic diseases. One gram of GUARDIX-SGTM was applied on the abdominal viscera just below the umbilical port site and adjacent abdominal wall prior to fascia closure. The primary endpoint was the incidence of postoperative adhesion evaluated by visceral sliding technique through transabdominal sonography after three months. Between June 2019 and March 2020, a total of 37 healthy patients without any history of previous abdominal surgery received SPA laparoscopic surgery by a single surgeon. No postoperative complications such as wound dehiscence or surgical site infection occurred during the follow-up period of three months. No postoperative adhesion around the umbilicus was noted in all 37 patients. The mean visceral movement measured by transabdominal sonography during maximal respiration was 4.9 cm (4.9 ±â€Š1.9 cm). Using an adhesion barrier around the port site prior to fascia closure prevents postoperative adhesion in benign SPA laparoscopic gynecologic surgery.

RESUMO

RATIONAL: Reconstruction of complex craniofacial defects in fronto-orbital region has been reported to be extremely few. In this study, we report 2 cases with fronto-orbital defects of different etiologies in one-stage surgical reconstruction with polyetheretherketone (PEEK) prosthesis using computer-assisted design and computer-assisted manufactured (CAD-CAM) techniques. PATIENT CONCERNS: One patient was a 49-year-old man, who admitted with a depressed and comminuted fracture in the left fronto-orbital region as a result of a motor vehicle collision. The other patient was a 45-year-old woman who was hospitalized with an unexpected diagnosis of a fronto-orbital bone tumor during a head CT examination in a minor traumatic brain injury. None of them had a significant past medical history. DIAGNOSES: The first patient's head computed tomography (CT) showed multiple depressed comminuted fractures in the right fronto-orbital region with localized frontal lobe contusion, and the diagnosis was clear when combined with the mechanism of traumatic head injuries. The second patient's head CT and magnetic resonance image suggested a right lateral orbital neoplastic lesion that distorted peripheral bone, the postoperative pathological examination demonstrated an osteoma with fibromatous hyperplasia, and thus the women's diagnosis was confirmed. INTERVENTIONS: A three-dimensional image of both patients' skull bone were collected from a high-resolution CT. A virtual surgical planning for lesion excision and defect remodeling based on CAD-CAM techniques was undertaken, and than the reconstruction surgery was performed in a single procedure using PEEK prosthesis. Antibacterial treatment was prescribed routinely. OUTCOMES: Postoperatively, both patients achieved excellent aesthetic restoration as well as functional recovery of the orbital cavity without neurological or infectious complications during an average 22 months follow-up. LESSONS: The CAD-CAM PEEK implants could be a preferred option for reconstruction of patients with various complex fronto-orbital defects.

RESUMO

INTRODUCTION: Although the traditional bilateral surgical approach to treat hiatal hernia (HH) with gastroesophageal reflux disease (GERD) can provide local protection of the vagus nerve, the integrity of the entire vagus nerve cannot be evaluated. Therefore, we developed and described the total left-side surgical approach (TLSA), which theoretically reduces injury to the vagus nerve, and described the detailed surgical procedure. METHODS: Initially, we performed a cadaver study to explore the characteristics of the vagus nerve. Then, we prospectively evaluated the TLSA in 5 patients with HH and GERD between June 2020 and September 2020. Demographic characteristics, surgical parameters, perioperative outcomes, and follow-up findings were analyzed. RESULTS: The TLSA was successfully used in five patients (40-64 years old), and no major complications were noted. The median total operative time was 114 min, median blood loss was 50 mL, and median postoperative hospital stay was 3.8 days. Gastrointestinal function recovered within 4 days of surgery in all the patients. The 6-month follow-up gastroscopy examination showed well-established gastroesophageal flap valves. Compared with the baseline results, the 6-month follow-up results showed lower values for the total GerdQ score (12.4 vs. 6.2) and the total esophageal acid exposure time (3.48% vs. 0.38%). Based on the European Organization for Research and Treatment of Cancer quality of life questionnaire-stomach module 52 results, the incidence of dysphagia and flatulence decreased over time after the TLSA. CONCLUSIONS: The TLSA provides a clear and broad surgical field, less trauma, and rapid recovery; moreover, it is technically simple. Although our results suggest that the TLSA provides safety and short-term efficacy and is feasible for patients with HH and GERD, long-term results from a larger clinical trial are needed to validate these findings. Trial registration ChiCTR2000034028, registration date is June 21, 2020. The study was registered prospectively.

RESUMO

OBJECTIVE: To analyze the disease types, clinical manifestations, efficacy and outcome of JAK2 V617F and BCR-ABL double-mutant myeloproliferative neoplasms (MPN), and provide a reference for the diagnosis, treatment and prognosis of MPN. METHODS: The clinical characteristics, diagnosis, therapeutic efficacy and outcome of JAK2 V617F and BCR-ABL double-mutant MPN were analyzed comprehensitively by combining a clinical case diagnosed and treated in our hospital with literature cases from CNKI and PubMed databases. RESULTS: A total of 38 related literatures were retrieved from the two databases by searching "JAK2 V617F" and "BCR-ABL" as key words from 1990 to 2019, and 59 cases were involved. Among all the 60 cases, 41 were males (68.3%) with a median age of 61 (32-77) years old, while 19 were females (31.7%) with a median age of 58 (21-82) years old. The BCR-ABL fusion gene and JAK2 V617F mutation were found simultaneously in 21 cases (35%), 19 cases (31.7%) with JAK2 V617F mutation were found during the treatment of Philadelphia chromosome (Ph)-positive chronic myelogenous leukemia (CML). Ph+CML was detectable in 20 cases (33.3%) during the treatment of JAK2 V617F mutation positive MPN. Polycythemia vera (PV) was the most common MPN coexisting with CML (30%), followed by essential thrombocythemia (ET) (26.7%) and primary myelofibrosis (PMF) (21.7%). In addition, there were 13 cases (21.7%) not classified in the literature. Among the 60 cases, 35 CML patients were clearly staged, including 31 in the chronic phase, 3 in the accelerated phase, and 1 in the blast crisis phase. As for the subtypes of BCR-ABL fusion gene, there were 30 cases with clear classification, including 28 cases of p210, 1 case of p190 and 1 case of p230. CONCLUSION: As cases of BCR-ABL and JAK2 V617F double-mutant MPN are reported, simultaneous detection of JAK2 V617F mutation and BCR-ABL fusion gene in MPN patients is necessary to avoid misdiagnosis and missed diagnosis.
